4 Claims. (Cl. 45-139) This invention relates to an attachable adjustable elevating and supporting device.
One of the objects of this invention is to provide an attachment which may be detachably secured to the legs of an article such as a chair, bed, table or the like for supporting same in any desired elevated position.
Another object of this invention is to provide an attachable device "of the foregoing character which is also provided with self-leveling means to maintain the supporting article in a level position.
Another object of this invention is to provide a device of the foregoing characteristics which is inexpensive to manufacture, which may be readily attached to the legs of an article for supporting same in anydesired elevated position, which is readily detachable therefrom, which is adjustable with respect to the leg for varying the elevation of the article,'and which is so constructed that it may accommodate and be attached to legs of different diameters.
Other objects will become apparent as this description progresses.
In the drawings:
Figure 1 is a perspective view showing the device of this invention attached to a chair for supporting same in an elevated position. 1
Figure 2 is an enlarged side elevational view showing the device attached to the leg of an article.
Figure 3 is a rear elevational view of Figure 2.
Figure 4 is 'an exploded perspective view of the parts of this device.
Figure 5 is a view partly in cross-section taken on lines 5-5 of Figure 2, and V Figure 6 is a cross-sectional view taken on lines 66 of Figure 2.
The attachment includes a supporting member which is formed principally of two sections or plates generally indicated at 12 and 14. The sections 12 and 14 are made preferably of steel or the like and are shaped as shown. two sections and is generally of concave shape or generally semi-circular in cross-section throughout the major portion of its length. At the bottom it is bent inwardly at its opposite sides and shaped to form a split annular portion 16 to which the self-leveler generally indicated at 18 is secured.
The self-leveler 18, best shown in detail in Figure 6, includes an annular base member 20 having an upstanding annular portion 22. A member 24, made of fiber,
1 rubber or the like is secured within the base member 20 and said member has a neck 24' which extends above the upstanding annular portion 22. The neck 24' terminates in an inwardly extending lip 26.
A short tubular member 28, provided with a raised generally concave shaped bottom 30 fits over the neck portion 24 of member 24. A stud 32, having its head 34 loosely secured within the central bore 36-of member 24-passes through a central opening in the bottom 30 of the tubular member 28. The head 34 of the stud 32 Section or plate 12 is the longer of the 'ice is retained within the neck 24 by the inwardly extending lip 26. A U-shaped metal member 42 is secured to the stud 32. v p
The se1f-leveler 18 is secured to the split annular portion 16 at the bot-tom of section 12 so that the tubular member 28 of the leveler engages and surrounds the annular portion 16 and the U-shaped member 42 extends into the annular portion 16 to lock same thereto. The base member 20 is thus pivotally movable with respect to tubular member 28, as well as section 12, to permit the leveler to compensate for an unevenness of the floor. The tubular member 28 of the leveling device is permanently secured to the split annular portion 16 of section 12 by crimping or other means, with the U-shaped member 42 extending inwardly thereof.
The upper portion of section 12 is interiorly lined with a padding or felt material 44 to prevent marring of the leg of the article supported. Section 12 is provided with a plurality of spaced openings 46 along the longitudinal center line of section 12.
The section 14 is likewise lined with a padding 58 and is provided with an enlarged opening 60 adjacent the top of the extension 48 to accommodate an internally threaded sleeve 62 having a hexagonally shaped head 64.
When sections 12 and 14 are coupled around the leg L of the chair or other object to be supported, as best shown in Figures 2 and 3, the upper portions of sections 12 and 14 will embrace the leg and marring thereof will be prevented by the padding. The sleeve 62 extends inwardly into section 12 and is. engaged by a threaded bolt 66 passing through one of the openings 46 in section 12. This couples sections 12 and 14 about the leg L. The bottom of the leg L rests on and is additionally supported by the sleeve 62. The enlarged opening 60 in section 14 is slightly larger than the outside diameter of the sleeve 62 to allow for a slight free play or tilting of section 14 with respect to section 12. The threaded bolt 56 is adjusted with respect to section 12 to position tions 12 and 14 immovably with respect to each other. The bolt 56 engages the inner wall of section 12.
The supporting height of the device may be selectively adjusted dependent on the number of openings 46 provided in section 12. Three openings 'are shown for purpose of illustration .although the number may be varied. As shown in Figures 2 and 3, the threaded bolt 66 issecured in the uppermost opening in section 12 and with the section 12 and 14 thus coupled about the leg L, this device supports the leg in its most elevated position. To lower the height, the bolt 66 is inserted in any of the lower positioned openings 46 and section 14 is coupled to section 12 as previously explained. By so doing, the elevation of section 14 with respect to section 12 will be lower than that shown in Figures 2 and 3,, nevertheless, the coupling will be as previously described and will be firmly positioned around the leg. The bottom of the leg will also rest on the coupling sleeve 62, as heretofore described. The leveling means 18 will compensate for any floor unevenness.
This device may be quickly and easily attached to the legs of any object to support same in any desired elevated position and may readily be detached therefrom. Also, due to the complementally shaped sections 12 and 6 14, this, device may be attached to legs of varied diameters.
It will be understood that various changes and modifications may be made from the foregoing without departing rfromjhe spirit, and scope of, the appended .claims.
1. In a device of the character described comprising a pair. of; sections, each of said sections. being generally semi-circular incross section, one of said sectionshaving a plurality. of, spaced. openings, transverse means selectively. positioned in anyof saidopenings and engaging the other sectionfor securing said sections around the leg of anarticle to surround same and engage and support the leg inany selectedelevatedposition, said transverse means being positioned below the leg so that. the leg rests on same.
2 In a; device of the character. described comprising a pair of sections. withone of said sections being longer than the other section,,each of said. sections being generally serni circular in cross-section, means extending transversely between said sections for securing said sections aroundthe leg-ofan article tov surround same and engage and. support the leg in: an-e'levated position, said transversely extending means being positioned below the leg so that the leg rests on same.
