Description:
The invention relates to and comprises a bathtub safety device for use while entering and leaving a conventional bathtub. In particular, it relates to a device that is equipped with means that facilitate attachment of the inventive apparatus and device to an existing and installed tub structure with a minimum of expense and difficulty.
In the prior art many supporting devices, safety grips, towel bars, folding seat arrangements and other bathroom fixtures have been utilized without solving the existing problems that many people encounter. Many elderly persons, particularly those with physical disability or impairment, have a great need for the use of supporting devices or aids to assist them in getting into and out of an ordinary bathtub.
These needs have not been met by the prior art devices available on the market for a number of reasons. In the prior art U.S. Pat. to Dunn No. 2,243,794 certain support structure is disclosed. In one embodiment of this invention the support structure actually fastens across the interior of the bathtub, causing a loss of use of a part of the tub, which is not desirable. In another embodiment as shown in FIG. 2 of this patent, a wall adjacent to the back of the tub is used to mount the supporting device. This is impractical in many settings for a number of reasons. In the first instance, it requires considerable skill to install. Secondly, in many situations the wall without the installation of additional supporting structure is really not strong enough to support a person, when the full weight is applied to the supporting device. Thirdly, the device as mounted in FIG. 2 is in an area where many persons would be unable to grasp the supporting structure and therefore would not be positioned properly for widespread use.
In another prior art device, U.S. Pat. No. 2,045,815 to Wiesjahn, discloses a combined bathtub safety grip and towel rack. In this device the combined grip and towel rack is fastened entirely to the sidewall of the tub by means of saddle brackets that straddle the sidewall of the tub and are fastened thereto by bolt members that can by means of screw threads put pressure on the sidewall of the tub. This mounting arrangement is not adequate as it does not transmit any of the user's weight to the floor.
In this invention applicant's device, which has advantages over all the prior art bathtub safety structures known to the invention, combines two complementary features. In this invention means are utilized to fasten the bathtub safety structure directly to the sidewall of the tub and to the floor adjacent to the tub. Each fastening means is used to facilitate a proper distribution of weight and resistance to turning moment to obtain advantages not shown in the prior art.
It is therefore one object of this invention to provide a simple, relatively inexpensive bathtub safety appliance that is superior to those in the prior art and/or on the market at the present time.
It is a further object to provide a simple inexpensive bathtub safety appliance that is easy to install.
It is one additional object of this invention to provide a bathtub safety appliance that can be attached to both the floor and one sidewall of the tub with a minimum of difficulty and expense.
It is also one additional object of the present invention to provide a relatively simple and inexpensive device that can be used by elderly and/or handicapped persons to assist themselves into and out of a tub in a safe manner.
It is another object of the instant invention to provide a bathtub safety device that is substantially secured both to the tub wall and the floor in order to utilize maximum support means and to prevent and suitably resist all turning moments so as to create a feeling of security in the user.
It is a further object of the invention to provide an improved bathtub support device that can be used by children and adults alike.
FIG. 1 of the drawings illustrates an assembly of one embodiment of the inventor's bathtub safety appliance. In this figure a rod or tube 10, that may preferably be made of steel tubing or solid steel rod, is designed to be secured to the tub and to the floor in a substantially vertical plane adjacent the sidewall of tub to be entered. A baseplate 11 is suitably secured to the base or bottom of rod 10 and one or more handle members 12 may be suitably affixed to or rigidly placed through rod 10 at or near its upper end. The opposite ends of each handle member 12 may be covered with a rubber or plastic cover 13 that is used to cover the opposite ends of each handle member. These covers 13 facilitate a secure grip by the user and are preferably used in one embodiment of the invention to prevent falls. A cylindrical sleeve or collar 14 is provided and fits about the midsection portion of the vertically disposed rod 10, the said sleeve having a substantially horizontal extension 15. The sleeve member 14 is designed to slide vertically along the rod 10 so that extension 15 will be located directly on top of or adjacent to the top of the sidewall of the tub. A screw or other projecting means 16 may be directed through the wall of the sleeve 14, for example, by a threaded member 17 located adjacent to or in the wall of the sleeve 14, in order to secure the sleeve and extension in the desired position on rod 10. A fastening member 18 having a substantially vertical depending member 19 may be secured to extension 15 to rigidly affix rod member 10 to the sidewall of the tub. Depending member 19 may be inclined at an angle to allow it to fit the sidewall of the tub. In one preferred embodiment of this invention fastening element 18 may be comprised of a cylindrical or square tube that slides on and telescopes over extension 15. A bolt 20 may be threaded or placed through an aperture 21 in the end of fastening member 18 so as to firmly affix the fastening member to extension 15 by means of a conventional bolt 20. The lateral opening in extension member 15 may be threaded to accept the threads on bolt 20. Other equivalent means of fastening may be used. In the assembly of the inventive safety device as shown in FIG. 1, the cylindrical sleeve or collar 14 may be adjusted for height so that the lower edge of extension 15 rests directly on top of or near the top of the sidewall of the tub to which the device is to be fastened and a screw 16 (which may be an Allen screw) may be directed through the wall of the sleeve through a threaded aperture 17, so as to make a contact with or to go through the wall of the tube or rod 10. The fastening member 18 is then positioned about the extension 15 and the machine bolt 20 placed through aperture 21 and threaded into a horizontally disposed aperture extending horizontally through extension member 15. As the bolt 20 is progressed through the screw threads of the threaded aperture extending horizontally into extension 15 the inside wall 22 of the substantially vertically positioned member 19 comes into contact with from interior sidewall of the tub 22A. The wall 22 may be coated if desired with rubber, plastic or other abrasive or adhesive materials cushioned to prevent tub damage that will give an especially strong and secure bond to the tub wall as the screw or bolt 20 is brought to its final secured position. The upper end of rod 10 may be covered with a soft plastic or rubber tip 23 to protect the user from falling on or coming into contact with the upper end of rod 10. The baseplate 11 illustrated in FIG. 1 may be equipped with a number of apertures 11A through which screws or bolts may be placed in order to secure the base member or element 11 to the floor. Baseplate 11 may be welded or securely connected to vertical rod 10 by any conventional means.
FIG. 2 of the drawings illustrates a modified sleeve and extension for securing the midsection of the vertical rod or support member to the sidewall of the tub. The modified sleeve illustrated in FIG. 2 comprises a tubular sleeve member 23 having a horizontal extension 24 which may, in one preferred embodiment, be comprised of tubing of a smaller diameter than that making up the sleeve member 23. The fastening member 25 may be made of a larger piece of tubing so as to telescope over the horizontal extension 24. The horizontal fastening member 25 may be extended at essentially a right angle, or slightly greater than a right angle, to form a tub-engaging element 26. Element 26 may be flattened or take any desired shape so that it may make firm contact with the interior wall of the tub. As previously disclosed, element 26 may be coated with any adhesive material, or plastic, rubber, or other material that will give firm contact and also protect the tub from damage. A screw or bolt 27 may be placed through aperture 28 in one exterior wall of fastening element 25 so that the screw or bolt can be threaded into a threaded aperture in horizontal extension 24. The lower portion of the sleeve may be covered with a rubber or plastic cushion 29 in order to protect the outside wall of the tub.
FIG. 3 illustrates an alternate means for attaching base member 11 to the floor. It should be understood that screws, bolts or other elements may be used to attach base member 11 to the floor or in conjunction with a clip or flange to fasten base member 11 in FIG. 1 to the floor. In FIG. 3 either one or a plurality of suction cups 30 may be used on either end of the base member 11 to secure baseplate or member 11 to the floor. As illustrated in the drawings the suction cups 30 may be off center with the larger area away from the tub or in the alternative these suction cups may be centered beneath support member 10.
As illustrated in FIG. 3 an alternate means may be used to fasten baseplate 11 to vertical support rod 10. For example, in this embodiment, a piece of tubing or other similar material may be welded as at 31 to the base 11 to a section of tubing 32 and be allowed to telescope with a larger single piece of tubing 10. In such a case the larger tubing 10 will telescope around the inside tubing that is welded to the base. A screw or other fastening means may be used to fasten the adjacent walls of vertical rod 10 to the welded projection on base member 11.
Another alternative structure that comes within the broad scope of this invention includes a vertical support member 10 as illustrated in FIG. 1 made with a unitary sleeve and horizontal extension member that is not free to slide at any time along the midsection of rod 10. In such a case the horizontal extension 15 as illustrated in FIG. 1 may be made a desired height from the floor, knowing the exact height the wall of the tub is in such a case. Such a structural arrangement is not as advantageous as with a movable sleeve as shown in FIG. 1 but should be considered to come within the broad scope of the inventive concept disclosed by the inventor.
In such a case the horizontal extension element and a depending fastening member may be secured to rod 10 by a bolt or screw 27 as illustrated in FIG. 2.
