ADJUSTABLE SHELVES AND SUPPORT THEREFOR
United States Patent 3705654
Especially suitable for use in confined areas such as the inside of a panel truck end support units fabricated from plated steel wire each includes vertical posts or standards drilled at spaced intervals with the holes in front post being substantially in alignment horizontally with the holes in the back post. Shelves fabricated from plated steel wire are easily located and removably attached to both of the end panels in the holes of the post thereof from one side of the assembly which may be the aisle of a panel truck. Each shelf is held in place by rearward projecting and horizontally disposed pins on each end of the shelf and each pin being inserted in their respective aligned hole in the back post of the assembly and rearwardly depending ends on each end of the front of a respective shelf which likewise is positioned in the corresponding hole in each of the front post. Shelves are positioned and placed for use by aligning the respective pins at the front and the back of the shelf with the respective openings in the vertical posts and then pushing the shelf rearwardly into position. The shelf is removed by pulling same forward. Optionally a spring member made from a piece of bent and looped wire is pressed out of the way for insertion of the shelf and permitted to spring into position behind the post once the shelf is seated in the respective holes thereby preventing accidental dislodgement of the shelf. The spring member is displaced manually by pressure from one finger while holding on to another part of the shelf.

Description:
BACKGROUND OF THE INVENTION
1. Field of the Invention -- Classification
Generally supports and racks and more particularly supports having adjustable shelving thereon where the shelves are engaged in spaced locations on the supports.
2. Description of the Prior Art
The prior art includes U.S. Pat. Nos. 2,315,595; 2,447,704; 2,600,191; 2,761,568; 3,007,708; 3,101,148; 3,343,506. The use of wire shelves with ends which attach to columns or other types of vertical support means is old in the art. These shelves employ some type of engagement between the shelves and the supports which must be manipulated and disengaged and again manipulated to replace the shelves. The prior art shelves disclosed in the above noted patents are not entirely suited for use in confined spaces such as the inside of a panel truck which has only a small aisle space in the middle and shelves on both sides from which the personnel must remove merchandise or equipment as for example in repair trucks such as telephone and other similar types. While the prior art shelves can be removed and replaced in different positions the operation sometimes requires the removal of screws or other similar fasteners and the replacement thereof. This is extremely time consuming and tedious and annoying to repairmen who are mainly interested in getting the necessary repair parts onto the truck in proper place and in getting the shelves adjusted readily to receive the particular size merchandise placed thereon.
SUMMARY OF THE INVENTION
By having the vertical supports both front and rear provided with holes which face towards the front which would be the aisle of a truck and having the shelves with horizontal projecting shelf retainer members which insert by alignment into respective openings and then are readily seated by slightly pushing the shelf toward the rear the problem of manipulation has been simplified and the use of removable fasteners and brackets has been eliminated altogether. Through the use of the optional spring latching member on the shelf the problem of accidental dislodgement or disengagement of the shelf has been practically eliminated.

FIG. 6 is a side elevation view illustrating a variation of the installation of the shelf.
DESCRIPTION OF THE PREFERRED EMBODIMENT
It should be understood from the outset that while there is illustrated only one or two shelves in the present disclosure this is not a significant number by any means since the number of shelves is variable depending upon the installation and may be increased or decreased as desired.
The entire assembly is designated by reference numeral 10 and comprises four spaced vertical posts or standards 12,14,16 and 18 which for the sake of description only are referred to as the rear posts 12, 14, and the front posts 16, 18. Actually, rear post 12, and the front post 16 are part of an integral end panel constructed from welded wire as are rear posts 14 and front post 18. Each of the end panels are designated in assembly by reference numeral 20 and each comprises the respective front and rear posts 12, 16 and 14, 18 connected together transversely by welded wire members 22 which for the sake of appearance and durability are plated with chrome or other material and which are connected together vertically and longitudinally by spaced wires 24 altogether forming the rigid wire panel assembly 20. Each of the posts 12, 14, 16 and 18 have been drilled at spaced intervals to provide openings or holes 26 which when the two panels 20 are assembled in spaced relationship in the manner shown in FIGS. 1 and 2 provide the openings 26 in spaced alignment horizontally and vertically so that a set of holes 26 on posts 12 has a corresponding hole horizontally therefrom on post 16 as does post 14 and 18. By means of these openings or holes 26 a shelf designated generally by reference numeral 30 may be positioned in a set of holes 26 in horizontal arrangement.
Posts 12, 14, 16 and 18 may be hollow, plated tubing or conduit in which as shown in FIG. 2 may be inserted bottom support brackets which are bracket 34 having a foot 35 with an upstanding cylindrical collar 36 thereon with a threaded stud 37 inserted inside the post 12 nd screwed in place into the floor 38 of a panel truck 40. The front posts 16, 18 may be provided with an adjustable foot 42 having a bottom disc floor engaging member 44 thereon to which is attached a threaded stud 46 adjustably threaded into a threaded bushing 48 inside the bottom end of the posts 16, 18. With this arrangement the posts 12, 14, 16 and 18 may be installed with the respective panels 20 in spaced relationship on the floor 38 of a typical van or panel truck 40 which could be a telephone truck or similar repair truck. The entire assembly 10 may extend from the floor all the way to engage the ceiling 48 of the truck or closely thereto.
Each shelf assembly 30 comprises a longitudinal front bar 50 and a corresponding longitudinal rear or back bar 52 which may be chrome plated metal strips. The front bar 50 and the back bar 52 are connected into a rigid shelf assembly 30 by means of transverse plated wire members 54 welded wherever there is an intersection such as 60 with member 50 and 62 with member 52 and to the transverse wire members 54 there is welded a plurality of longitudinal wire members 66 arranged in spaced relationship from one end of the shelf 30 to the other end. Additional transverse strengthening means is provided by transverse wire members 70 at spaced locations longitudinally across the shelf which are welded at points of intersection such as 72 with the respective longitudinal wire members 66. This provides a rigid shelf assembly 30.
One of the longitudinal wire members at the front of the shelf assembly 30 designated by reference numeral 76 projects beyond the end of the shelf assembly 30 represented generally by the members 54 and has a 90° bend in it providing a projecting member 78 on each end of the member 76 which is a pin insertable in a respective opening 26. Another one of the longitudinal members designated by reference numeral 80 is similarly constructed to member 76 with projecting pins 82 on each end thereof which are arranged in length and dimension with respect to the distance between the end panels 20 to fit exactly into a matching and respective and corresponding opening 26. Ordinarily a typical set of openings such as those designated for purposes of illustration as 26a,b,c and d in FIG. 1 would be in horizontal alignment to receive a shelf 30 as would be all of the other respective openings 26 above and below same. Therefore a shelf 30 and in fact any other shelves 30 may be installed in any one of the sets of holes 26 at any elevation and any other shelf 30 may be installed at the immediate next set of holes. A shelf 30 may be placed as close to another shelf above or below same as the distance between one hole 26 and the next lowermost or uppermost hole 26. This makes it possible to provide short shelf space where coils of wire or other things are being used which do not require a great deal of head room between shelves.
Optionally, to hold the shelf securely in place and practically eliminate any chance of dislodgement thereof, a latching means designated generally by reference numeral 90 is provided on each end of the shelf 30 and it comprises a spring latching rod member 92 which is constructed by bending another one of the longitudinal shelf members 94 at each end thereof into the rod member 92 and thence into a loop 94 which is looped about the transverse member 54 of shelf 30. The face of the loop 94 is spaced such in the construction and design as to be approximately the distance from the end of the respective member 76 discounting the length of portion 78 so that after the shelf 30 has been inserted and seated in place the latch member is behind the respective post 16 or 18 since normally these are used only on the front posts and are not necessary on the rear posts whereby the latch member may be released and will spring behind the posts 16 or 18. This prevents the shelf 30 from being pulled forward either accidentally or intentionally until the fingers of the hand are used to depress the member 92 into almost co-extensive engagement with the member 54 so that the shelf will clear the posts 16 and 18.
In FIG. 6 it is illustrated how a shelf 30 may be misaligned in a set of openings 26 so that the rear of the shelf at member 52 is higher than the front shelf at member 50 and obviously to one skilled in the art the shelf could be mis-aligned in the other direction so that it tilts backwards instead of forward and vice versa. This may be advantageous when storing certain types of merchandise where it is desired that the merchandise be dispensed from the front.
The posts 12,14,16, 18 can be a free standing structure rather than installed in a truck with brackets 34 and foot 42. Posts 12, etc. can be connected in any manner to make them free standing whether or not in a truck, on the ground, a floor, etc.
While I have shown and described a particular embodiment of my invention together with a suggested mode of operation thereof and a particular desirable type of installation this is by way of illustration only and does not constitute any sort of limitation on the scope of the invention since various alterations, changes, deviations, substitutions, eliminations, additions, integrations, subtractions, removals, combinings and other departures may be made in the embodiment shown and described without departing from the scope of the invention as defined by a proper interpretation of the appended claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT
It should be understood from the outset that while there is illustrated only one or two shelves in the present disclosure this is not a significant number by any means since the number of shelves is variable depending upon the installation and may be increased or decreased as desired.
The entire assembly is designated by reference numeral 10 and comprises four spaced vertical posts or standards 12,14,16 and 18 which for the sake of description only are referred to as the rear posts 12, 14, and the front posts 16, 18. Actually, rear post 12, and the front post 16 are part of an integral end panel constructed from welded wire as are rear posts 14 and front post 18. Each of the end panels are designated in assembly by reference numeral 20 and each comprises the respective front and rear posts 12, 16 and 14, 18 connected together transversely by welded wire members 22 which for the sake of appearance and durability are plated with chrome or other material and which are connected together vertically and longitudinally by spaced wires 24 altogether forming the rigid wire panel assembly 20. Each of the posts 12, 14, 16 and 18 have been drilled at spaced intervals to provide openings or holes 26 which when the two panels 20 are assembled in spaced relationship in the manner shown in FIGS. 1 and 2 provide the openings 26 in spaced alignment horizontally and vertically so that a set of holes 26 on posts 12 has a corresponding hole horizontally therefrom on post 16 as does post 14 and 18. By means of these openings or holes 26 a shelf designated generally by reference numeral 30 may be positioned in a set of holes 26 in horizontal arrangement.
Posts 12, 14, 16 and 18 may be hollow, plated tubing or conduit in which as shown in FIG. 2 may be inserted bottom support brackets which are bracket 34 having a foot 35 with an upstanding cylindrical collar 36 thereon with a threaded stud 37 inserted inside the post 12 nd screwed in place into the floor 38 of a panel truck 40. The front posts 16, 18 may be provided with an adjustable foot 42 having a bottom disc floor engaging member 44 thereon to which is attached a threaded stud 46 adjustably threaded into a threaded bushing 48 inside the bottom end of the posts 16, 18. With this arrangement the posts 12, 14, 16 and 18 may be installed with the respective panels 20 in spaced relationship on the floor 38 of a typical van or panel truck 40 which could be a telephone truck or similar repair truck. The entire assembly 10 may extend from the floor all the way to engage the ceiling 48 of the truck or closely thereto.
Each shelf assembly 30 comprises a longitudinal front bar 50 and a corresponding longitudinal rear or back bar 52 which may be chrome plated metal strips. The front bar 50 and the back bar 52 are connected into a rigid shelf assembly 30 by means of transverse plated wire members 54 welded wherever there is an intersection such as 60 with member 50 and 62 with member 52 and to the transverse wire members 54 there is welded a plurality of longitudinal wire members 66 arranged in spaced relationship from one end of the shelf 30 to the other end. Additional transverse strengthening means is provided by transverse wire members 70 at spaced locations longitudinally across the shelf which are welded at points of intersection such as 72 with the respective longitudinal wire members 66. This provides a rigid shelf assembly 30.
One of the longitudinal wire members at the front of the shelf assembly 30 designated by reference numeral 76 projects beyond the end of the shelf assembly 30 represented generally by the members 54 and has a 90° bend in it providing a projecting member 78 on each end of the member 76 which is a pin insertable in a respective opening 26. Another one of the longitudinal members designated by reference numeral 80 is similarly constructed to member 76 with projecting pins 82 on each end thereof which are arranged in length and dimension with respect to the distance between the end panels 20 to fit exactly into a matching and respective and corresponding opening 26. Ordinarily a typical set of openings such as those designated for purposes of illustration as 26a,b,c and d in FIG. 1 would be in horizontal alignment to receive a shelf 30 as would be all of the other respective openings 26 above and below same. Therefore a shelf 30 and in fact any other shelves 30 may be installed in any one of the sets of holes 26 at any elevation and any other shelf 30 may be installed at the immediate next set of holes. A shelf 30 may be placed as close to another shelf above or below same as the distance between one hole 26 and the next lowermost or uppermost hole 26. This makes it possible to provide short shelf space where coils of wire or other things are being used which do not require a great deal of head room between shelves.
Optionally, to hold the shelf securely in place and practically eliminate any chance of dislodgement thereof, a latching means designated generally by reference numeral 90 is provided on each end of the shelf 30 and it comprises a spring latching rod member 92 which is constructed by bending another one of the longitudinal shelf members 94 at each end thereof into the rod member 92 and thence into a loop 94 which is looped about the transverse member 54 of shelf 30. The face of the loop 94 is spaced such in the construction and design as to be approximately the distance from the end of the respective member 76 discounting the length of portion 78 so that after the shelf 30 has been inserted and seated in place the latch member is behind the respective post 16 or 18 since normally these are used only on the front posts and are not necessary on the rear posts whereby the latch member may be released and will spring behind the posts 16 or 18. This prevents the shelf 30 from being pulled forward either accidentally or intentionally until the fingers of the hand are used to depress the member 92 into almost co-extensive engagement with the member 54 so that the shelf will clear the posts 16 and 18.
In FIG. 6 it is illustrated how a shelf 30 may be misaligned in a set of openings 26 so that the rear of the shelf at member 52 is higher than the front shelf at member 50 and obviously to one skilled in the art the shelf could be mis-aligned in the other direction so that it tilts backwards instead of forward and vice versa. This may be advantageous when storing certain types of merchandise where it is desired that the merchandise be dispensed from the front.
The posts 12,14,16, 18 can be a free standing structure rather than installed in a truck with brackets 34 and foot 42. Posts 12, etc. can be connected in any manner to make them free standing whether or not in a truck, on the ground, a floor, etc.
While I have shown and described a particular embodiment of my invention together with a suggested mode of operation thereof and a particular desirable type of installation this is by way of illustration only and does not constitute any sort of limitation on the scope of the invention since various alterations, changes, deviations, substitutions, eliminations, additions, integrations, subtractions, removals, combinings and other departures may be made in the embodiment shown and described without departing from the scope of the invention as defined by a proper interpretation of the appended claims.
