Description:
BACKGROUND
The interior of a closet is one of the most poorly illuminated places in a house. One reason for this is the presence in most building codes of inhibitions on the presence of lights within the closet. Typically such lights must be located at least 18 inches from the nearest shelf. This is true even when the light is actuated by the closet door so that it is normally turned off when the closet is closed. It is, therefore, desirable to provide a closet illumination that can be used in small closets where it is infeasible to place a light 18 inches from the shelf. It is desirable that such a closet illuminator be actuated in response to opening the closet door. It is desirable that the illuminator provide multiple uses such as decorative lighting, night lights and the like. It is desirable that the illuminator be adaptable to other locations, such as over window openings or the like.
BRIEF SUMMARY OF THE INVENTION
There is, therefore, provided in practice of this invention according to a presently preferred embodiment an illuminated header comprising an elongated channel having a sufficient length for spanning a closet doorway and at least a pair of electrical conductors extending along the length of the channel. Preferably a plurality of lamp sockets including means for contacting the electrical conductors are retained ar arbitrary locations along the length of the channel by elastic detents. A switch is connected to the channel in a similar manner at one or both ends for actuation in response to the closet door position.

These and other features and advantages of the present invention will be appreciated as the same becomes better understood by reference to the following detailed description of presently preferred embodiments when considered in connection with the accompanying drawings wherein:
FIG. 1 illustrates in fragmentary perspective an illuminated header constructed according to principles of this invention;
FIG. 2 illustrates in exploded perspective many of the details of the illuminated header;
FIG. 3 is a transverse cross-section through the header of FIG. 1;
FIG. 4 is an enlarged detail of a connector channel in the header;
FIG. 5 is a bottom view of the header and a typical lamp socket;
FIG. 6 is an electrical schematic for the header for a closet with two doors; and
FIG. 7 is a transverse cross section of a modified header suitable for folding rather than sliding closet doors.
DESCRIPTION
FIG. 1 illustrates in fragmentary perspective a portion of a wall 11 in which there is a doorway 12 to a closet. The doorway is closed by an inner door 13 and outer door 14 which are suspended in overhead tracks 17 (FIG. 3) by conventional hangers 18. Wheels 19 run along the length of the steel tracks 17 so that the two doors 13 and 14 are each free to slide away from the respective door jamb for opening the closet. Such sliding door closet openings have been conventional for a number of years.
An illuminated header 21 spans the top of the door frame and extends a short distance into the room outside the closet. As better seen in FIGS. 2 and 3, the header comprises a roll formed sheet steel plate 22 having a uniform cross-section along its length. The plate has a plurality of screw holes 23 along its length so that it can be secured to the door frame 24 along the top. A stiffening bead 26 is provided along the inner edge of the plate. A J-shaped flange 27 is provided along the outer or exposed edge of the plate for stiffening and for receiving and retaining a decorative fascia 28. It will be apparent that if desired the fascia 28 may be made integral with the plate 22 or that the tracks and header be made integral for further economy in manufacture and installation. In the illustrated arrangement the fascia is made imperforate, however, if desired decorative piercework can be provided in the fascia and translucent sheeting provided behind the perforations.
A pair of opposing generally V-shaped beads 29 extend along the length of the plate for retaining a generally U-shaped plastic channel or connector strip 31 in firm engagement. The base of the channel has lateral protrusions 32 (FIG. 4) which are engaged by the beads 29 continuously along the length of the header. If desired in some embodiments the continuous beads 29 can be omitted and intermittent tabs punched and bent from the plate can be used for engaging the lateral edges 32 of the channel. If desired the plate and channel can be made integrally in a single plastic extrusion.
The channel 31 which comprises an extrusion having uniform cross-section along its length is illustrated in enlarged cross-section in FIG. 4. The plastic is one having substantial rigidity to provide a secure structural member and also having sufficient ability to elastically deform that it will accommodate electrical conductors and connectors as hereinafter described. The base of the channel (which is at the top when installed) has four raised members 33 and 34 which collectively define three generally circular secondary channels for accommodating an electrical conductor. The conductor comprises a circular insulating sheath 36 of resiliently deformable plastic and a multiple strand metallic wire 37 within the sheath. The center channel has a pair of grooves 38 which permit the raised members 33 to deform laterally for receiving the center conductor sheath 36 which is preferably pressed in place after the channel has been extruded. This is preferred since the mechanical properties of the insulating sheath 36 are different from the desired properties of the channel 31. Otherwise the channel 31 could be extruded with electrical conductors imbedded in plastic. The channels for accommodating the two outer sheaths 36 also have relief grooves 39 which permit deflection of the outer raised members 34 for insertion of the respective conductive sheath.
The channel 31 has a pair of depending flanges 41 each of which has a stop 42 on the inside. The stops 42 and the edges of the raised members 22 and 34 serve to limit the extent of insertion of elements into the channel. Each channel includes a detent groove 43 near the outer edge of the flange. Flaring lips 44 beyond the detent grooves 43 help during insertion of electrical elements into the channel.
Referring again to FIGS. 2 and 3 and the parttial bottom view of FIG. 5, the illuminated header is provided witha plurality of lamp sockets 46 which may be inserted into the channel 31 at any desired location. An ordinary 71/2 watt incandescent light bulb 47 of the type commonly used in night lights and the like is mounted in each lamp socket. Since the lamp sockets can be inserted at any arbitrary location along the length of the channel, any desired number and spacing of lamps can be used. Thus, for example in a 4-foot closet opening, from four to six bulbs evenly spaced may be used for adequately illuminating the closet interior. If a householder desires additional lighting it is only necessary to add additional lamp sockets with additional bulbs. The lamp sockets can be freely rearranged to maintain uniform spacing or any other desired arrangement. The use of a plurality of small lamps gives great adaptability to the header and the small lamps give a soft lighting that is quite decorative as well as useful.
Each of the lamp sockets 46 has a body in the general form of a rectangular parallelepiped. On the bottom face of the socket is a receptacle 48 in which the bulb is threaded for making electrical contact. Each socket has a pair of parallel side faces 49, each of which has a detent ridge 51 extending along its length in a direction parallel to the bottom face of the socket. The two ridges 51 are complementary to the detent grooves 43 (FIG. 4) in the channel 31. Thus when the socket is inserted into the channel, the detent ridges 51 elastically force the flanges 41 apart until they snap into the detent grooves 43. These cooperating detent moieties serve to retain the socket in place in the channel. Clearly many variations can be made in the detents for inhibiting withdrawal of the sockets from the channel. The simplest is mere reversal of the detent moieties.
A sufficient force on the socket can be applied for overcoming the detents and removing it from the channel as desired. For this purpose a pair of ears 52 are formed at each end of the socket to permit it to be grasped by the fingers for pulling it from the channel.
On the top face 53 of the socket there is a pair of metal points 54 which are sufficiently long to perforate the plastic sheath 36 and engage the wire 37 in each of the two outer conductors in the channel. The two outer conductors and the points 54 are symmetrically located so that the lamp socket can be inserted into the channel without regard to orientation. Thus, when electricity is applied to the outer conductors contact is made by the perforating tips 54 for illuminating the lamp in the socket.
Typically the lamp sockets are factory installed. If it is desired to rearrange the sockets, they are pulled out and pushed in in a new location. The electrical insulation around the wires is sufficiently resilient to close on the holes pierced by the points on the sockets. The sockets should not be slid along the channel since the perforating points and conductor sheaths may be damaged. Sliding of the sockets can be inhibited by serrating the inside of the channel and sides of the sockets. This requires forming after extrusion and is preferably avoided. Slight flaring of the ends of the side faces 49 on the sockets also gives resistance to sliding and is easily implemented.
Electrical power is applied to the conductors by way of one or two switch modules 56. Each switch module has a pair of detent ridges 57 on its side faces for engaging the detent grooves 43 in the channel 31 in the same manner that the detent ridges 51 on the sockets engage the channel. Thus a switch module can be placed at either or both ends of the channel for use in an illuminated header used as a closet illuminator. Although the illustrated switch modules are used at both ends of the header for actuation by the sliding doors, it will be apparent that other switch modules can be used for actuation by folding doors or, if desired, connector modules without switching can be used so that remote switches actuate the lights.
Each switch module 56 has three metal points 58 on the top face for making electrical contact with the three conductors embedded in the channel in the same manner that the points 54 on the lamp sockets make engagement. Three screw terminals 59 are provided on the end of the switch module for connection to an external electical circuit. Electrical connection is made to the screw terminals 59 in a conventional manner from a terminal box (not shown) in the wall adjacent the closet.
One of the screw terminals 59 is provided for a ground wire if desired. As better seen in the electrical schematic of FIG. 6 one of the screw terminals 59 is connected directly to one of the outer perforating tips 58, and another of the screw terminals is connected to the center perforating point 58 and also to one side of a switch 61. The other side of the switch is connected to the third (outer) perforating point 58. When two such switches are used in an illuminated header, they are connected in a similar manner at both end, however, the connection to an external source of electricity is made at only one end. When so connected one of the outer conductors and the center conductor in the channel are "hot" at all times. When either of the switches 61 is closed the other outer conductor is connected to the center conductor snd current applied to the lamps 47 which are in electrical contact with only the two outer conductors.
Each switch module also includes a pivot pin 62 on which a forked switching member 63 is mounted. The two arms of the fork straddle a bidirectional switch actuator 64 on the switch 61. An arm 66 is connected to the opposite end of the fork 63 and extends towards the closet so as to fit between the edge of the door and the door jamb. The switch 61 is normally ON in its center position and is OFF when pressed towards either the right or left. This is a momentary OFF position and the switch is spring biased to return to the central ON position.
When the closet doors are closed against the jamb the two arms 66 on the respective switch modules 56 are pressed laterally. This pivots the fork 63 and hence the switch actuator 64 so that both switches 61 are off. If either door is opened the respective switch 61 closes due to the spring bias of the switch, thereby lighting the lights in the header. Typically the switch modules are inserted into the channel in a position where the arm 66 is one-half inch or so from the door jamb. Thus, as soon as either door is opened about one-half inch the respective switch is turned on and illumination provided. When the door is completely open, illumination is provided within the closet. If it is desired to employ the illuminated header as a night light, one merely leaves the closet door slightly ajar. It turns out that the illumination provided on the normally closed closet doors from the illuminated header is quite attractive and one of the doors may be left slightly ajar for the decorative effect.
Some safety hazard could be encountered if the switch module to which electrical connection is made became dislodged from the illuminated header. This could occur since the three perforating tips 58 to which electricity is applied would be exposed. Means are therefore provided for inhibiting removal of the switch module after it is inserted into the channel. For this purpose a rigid U-shaped clip 67 is slipped over the end of the channel 31 after the switch module has been snapped into place. The arms of the clip straddle the depending flanges 41 of the channel and prevent them from being displaced laterally. This effectively prevents the detent ridges 57 from coming out of engagement with the detent grooves 43 and locks the switch module in place. The clip 67 can serve the additional function of shielding and insulating the ends of the conductors imbedded in the channel. An insulating tab on the switch module or other arrangement can also be used.
To install an illuminated header as hereinabove described, the plate 22 is fastened to the door frame 24 by a number of screws 68. A switch module 56 is pressed into the channel 31 at each end so that the arm 66 extends into the door opening for actuation by the doors. The U-shaped clip 67 is installed at each end to prevent spreading of the channel flanges 41. Electrical connection is then made to the screw terminals on one of the switch modules. The desired number of lamp sockets 46 are snapped into place in the channel 31 at the desired spacing. The decorative fascia 28 is then snapped into engagement with the flange 27 to conceal the switches and bulbs from the room without inhibiting illumination of the door fronts or the interior of the closet. A decorative end cap 69 is snapped on at either end to complete the illuminated header. The sockets and switch modules may be factory installed if desired since most closet openings are of standard size.
The illuminated header hereinabove described and illustrated is particularly adapted for use with sliding doors. Many closets are provided with double hung folding doors, a portion of which swings out into the room when the doors are opened. The above-described header must be modified for such installation so that the doors do not strike the switches, bulbs or decorative fascia. This can be accomplished by a specially formed plate that connects to the door frame which displaces the entire channel in which the sockets are placed up the wall outside the door frame. If desired connection can be made to the wall rather than the inside of the door frame. Another technique is illustrated in FIG. 7 wherein the channel is aligned so as to open horizontally instead of vertically.
As illustrated in this arrangement a conventional track 71 is connected along the top of the door frame for hanging and guiding a folding door 73 in a conventional manner. The hangers and guides between the door and track are conventional and have been omitted from FIG. 7. A generally L-shaped roll formed plate 74 is fastened to the door frame 72 by screws 76. The sheet 74 is formed so that it tightly grips a conductor channel 77 identical to that illustrated in FIG. 4. Lamp sockets 78 with bulbs 79 are snapped into the channel in the same manner hereinabove described. Similarly one or two switch modules (not shown) can be inserted in the channel so that actuation is provided by the closet doors. A decorative fascia 81 can be snapped over the plate 74 to complete the illuminated header. Clearly, if desired, the decorative fascia can be omitted and made integral with the sheet that supports the channel 77. Considerable variation can be provided in the mounting arrangements so long as the entire ensemble is high enough that the door clears it when it is open. Thus, for example, instead of having the channel orthogonal to the wall it can be tilted upwardly so that the outer end is higher and the bulbs point partially downwardly.
In folding and swinging door installations and the like, only a single switch may be used instead of one at each end of the header. In such an arrangement three conductors are not needed and two conductors are sufficient. Preferably these two conductors are spaced similarly to the three wire embodiment so that only one type of lamp socket is made. In the three wire arrangement a right hand and a left hand switch module are used. In a two wire arrangement the switch can be made for use at any location on the header.
Many modifications and variations in the present embodiments will be apparent to one skilled in the art. Thus, for example, the illuminated header can be combined with the hardware for drapes, venetian blinds, jalousies and the like. This provides an opportunity for illuminating a window opening and dramatic decorative effects can be obtained. Since electricity is provided in the illuminated header additional functions may be accommodated such as, for example, motorized operation of drapes, blinds, and the like. It will also be noted that the entire arrangement can be inverted from what is illustrated so that illumination is directed upwardly for very subdued indirect lighting. Many other modifications and variations will be apparent to one skilled in the art and it is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
The interior of a closet is one of the most poorly illuminated places in a house. One reason for this is the presence in most building codes of inhibitions on the presence of lights within the closet. Typically such lights must be located at least 18 inches from the nearest shelf. This is true even when the light is actuated by the closet door so that it is normally turned off when the closet is closed. It is, therefore, desirable to provide a closet illumination that can be used in small closets where it is infeasible to place a light 18 inches from the shelf. It is desirable that such a closet illuminator be actuated in response to opening the closet door. It is desirable that the illuminator provide multiple uses such as decorative lighting, night lights and the like. It is desirable that the illuminator be adaptable to other locations, such as over window openings or the like.

The clip 67 can serve the additional function of shielding and insulating the ends of the conductors imbedded in the channel. An insulating tab on the switch module or other arrangement can also be used.
To install an illuminated header as hereinabove described, the plate 22 is fastened to the door frame 24 by a number of screws 68. A switch module 56 is pressed into the channel 31 at each end so that the arm 66 extends into the door opening for actuation by the doors. The U-shaped clip 67 is installed at each end to prevent spreading of the channel flanges 41. Electrical connection is then made to the screw terminals on one of the switch modules. The desired number of lamp sockets 46 are snapped into place in the channel 31 at the desired spacing. The decorative fascia 28 is then snapped into engagement with the flange 27 to conceal the switches and bulbs from the room without inhibiting illumination of the door fronts or the interior of the closet. A decorative end cap 69 is snapped on at either end to complete the illuminated header. The sockets and switch modules may be factory installed if desired since most closet openings are of standard size.
The illuminated header hereinabove described and illustrated is particularly adapted for use with sliding doors. Many closets are provided with double hung folding doors, a portion of which swings out into the room when the doors are opened. The above-described header must be modified for such installation so that the doors do not strike the switches, bulbs or decorative fascia. This can be accomplished by a specially formed plate that connects to the door frame which displaces the entire channel in which the sockets are placed up the wall outside the door frame. If desired connection can be made to the wall rather than the inside of the door frame. Another technique is illustrated in FIG. 7 wherein the channel is aligned so as to open horizontally instead of vertically.
As illustrated in this arrangement a conventional track 71 is connected along the top of the door frame for hanging and guiding a folding door 73 in a conventional manner. The hangers and guides between the door and track are conventional and have been omitted from FIG. 7. A generally L-shaped roll formed plate 74 is fastened to the door frame 72 by screws 76. The sheet 74 is formed so that it tightly grips a conductor channel 77 identical to that illustrated in FIG. 4. Lamp sockets 78 with bulbs 79 are snapped into the channel in the same manner hereinabove described. Similarly one or two switch modules (not shown) can be inserted in the channel so that actuation is provided by the closet doors. A decorative fascia 81 can be snapped over the plate 74 to complete the illuminated header. Clearly, if desired, the decorative fascia can be omitted and made integral with the sheet that supports the channel 77. Considerable variation can be provided in the mounting arrangements so long as the entire ensemble is high enough that the door clears it when it is open. Thus, for example, instead of having the channel orthogonal to the wall it can be tilted upwardly so that the outer end is higher and the bulbs point partially downwardly.
In folding and swinging door installations and the like, only a single switch may be used instead of one at each end of the header. In such an arrangement three conductors are not needed and two conductors are sufficient. Preferably these two conductors are spaced similarly to the three wire embodiment so that only one type of lamp socket is made. In the three wire arrangement a right hand and a left hand switch module are used. In a two wire arrangement the switch can be made for use at any location on the header.
Many modifications and variations in the present embodiments will be apparent to one skilled in the art. Thus, for example, the illuminated header can be combined with the hardware for drapes, venetian blinds, jalousies and the like. This provides an opportunity for illuminating a window opening and dramatic decorative effects can be obtained. Since electricity is provided in the illuminated header additional functions may be accommodated such as, for example, motorized operation of drapes, blinds, and the like. It will also be noted that the entire arrangement can be inverted from what is illustrated so that illumination is directed upwardly for very subdued indirect lighting. Many other modifications and variations will be apparent to one skilled in the art and it is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
