ADJUSTABLE COMBINED ELEVATING AND SUPPORTING DEVICE Filed May' 20, 1936 Patented Mar. 2, 1937 PATENT OFFICE ADJUSTABLE COMBINEDVELEVAT'ING AND sorroa'rmqnnvion I Lena Baer, Topeka, Kans.
Application May 20, 1936, Serial No. 80,900
This invention relatesto an adjustable combined elevating and supporting device for a bed and has for its object to provide, in a manner as hereinafter set forth a device of such class that when employed in a set of four arranged in relation to the legs of an ordinary bed, it will convert the latter into a bed of hospital type.
A further object of the invention is to provide, in a manner as hereinafter set forth, a combined bed elevating and supporting means offering a great help to doctors and nurses in caring for patients in the home where the conveniences of the hospital are lacking, as it has been the habit of physcians and nurses in caring for patients in the home to increase the height of the bed by various makeshift methods, The adjustable combined bed elevating and supporting means in accordance with this invention not only overcomes the very troublesome problem of low beds that besets the physcian every time he is forced to care for a patient in the home, but further acts as a back-saver for anyone engaged in caring for the sick, more especially in home confinement cases.
Further objects of the invention are to provide, in a manner as hereinafter set forth, a device of the class referred to which is simple in its construction and arrangement, strong, durable, compact, readily installed with respect to the leg of a bed, conveniently adjusted, thoroughly eficient in the use intended therefor, and comparatively inexpensive to manufacture.
With the foregoing and other objects which may hereinafter appear, the invention consists of the novel construction, combination and arrangement of parts as will be more specifically described and are as illustrated in the accompanying drawing wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications may be resorted to which fall within the scope of the invention as claimed.
In the drawing: Figure l is a perspective view of a bed illustrating it as being supported in an elevated position by a set of adjustable combined elevating and supporting devices in accordance with this invention,
Figure 2 is a perspective view of the device 5 illustrating it in osition for supporting a leg of the bed. The lower portion of the leg is shown and the castor on the lower end of the leg is illustrated in dotted lines housed within the upper portion of the device,
Figure 3 is a top plan view of the device, and
Figure 4 is a side elevation partly in section.
With reference to the drawing, a bed is designated at 5 and its legs at 6. The lower end of each leg carries a castor wheel I as indicated in dotted lines Figure 2. 5
An adjustable combined bed elevating and supporting device in accordance with this invention includes a base 8 which may be hollow or solid and is illustrated by way of example as hollow and open at its bottom. The base 8 may be of 10 any suitable contour, preferably, it will be circular and is so shown. The body of base 8 at its top is formed with an axially arranged threaded opening 9 and an upstanding interiorly threaded collar I!) having its inner face forming a threaded l5 continuation of the threaded wall of opening 9.
The device includes a tubular pedestal ll of the desired height formed with an elongated slot 12 disposed lengthwise and intermediate the The body of pedestal II is also 20 provided with superposed circumferentially extending bayonet-shaped slots l3 which open at one end into one side of slot l2 adjacent the ends of the latter. The number of slots I3 may be as desired and by way of example only two 25 are shown. The pedestal H at its lower terminal portion is formed on its outer periphery with a group of threads It for engagement with the threads of the wall of opening 9 and the threads of the collar I 0 whereby base 8 and pedestal I I 30 are anchored together.
The device includes an upstanding vertically adjustable supporting element I5 which is disposed in telescopic relation with respect to the pedestal H. The element I5 is formed of a solid 35 shank I6 of the desired length provided adjacent its lower end with a laterally disposed stud I! for coaction with a selected slot l3 for the purpose of coupling the element IS, in its adjusted position to pedestal H, as well as for supporting and latching element l5 in such position. The slot l2 provides a clearance for stud I 7 when shifting shank l6 lengthwise of pedestal ll. Formed integral with the upper end or head part l8 of the shank I6 is a hollow extension IQ of segmental 45 contour which provides a segmental shaped socket 20 of less width than that of the head part IS. The extension [9 extends laterally in opposite directions with respect to head part IS. The mouth of socket 20 is of rectangular contour in plan. Integral with the upper end of and extended laterally in all directions, with respect to extension I9 is an annular cup 2| having a rectangular slot 22 in and diametrically of its bottom. The marginal portion of the bottom of 55 cup 2| is rounded. The cup 2i is of greater heighth than extension IS. The walls of slot 22 are flush with the walls of the socket 20 whereby communication is established between the cup and socket. The cup and socket are to receive the castor fitting 23 at the lower end of a leg of the bed. The socket 20 is to receive the castor wheel I when the device is in bed elevating and supporting position.
The manner of constructing the device provides for positioning a bed at different heights. Owing to the manner in which the pedestal, base and shank are connected together when the device is set up, the latter may be conveniently disassembled when occasion requires.
Although the device is designed primarily for use in elevating and supporting beds, it is to be understood that it is for employment in any connection for which it is found applicable.
What I claim is:
In an adjustable combined elevating and supporting means for a bed of the post type, an upstanding unit for receiving and supporting each post, said unit consisting of a base, a vertically adjustable standard anchored to the base, an open top combined castor wheel structure receiver, support and retarder element of segmental contour carried by the upper end of the standard, and an annular cup having its bottom formed with a diametrically disposed rectangular opening, said element being integral with the bottom of the cup and having its inner face registering with the edges of said opening.
