Description

Patented Nov. 7, 1950 UNITED STATES PATENT OFFICE HANDRAIL ATTACHMENT FOR. BEDS Wilmer L. Moyer and John C. Deck, Findlay, Ohio; L. Shirl Hatfield, administrator of said John C. Deck, deceased, assignor to said Moyer Application August 24, 1948, Serial No. 45,938 7 Claims. (01. -331) This invention relates to an improved assembly of hand rail for attachment to the upright posts of a bedstead, as for instance in the case of a hospital bed.

One object of our present invention is to devise a rail assembly that can be readily attached to or removed from a bedstead and is adapted to providegreater convenience and comfort for the occupant of the bed in changing his position or in exercising upon the bed or to provide increased safety and other advantages to be hereinafter more fully expained.

More specifically, the object of our invention is to provide an assembly which includes duplicate rails for attachment to the opposite sides of a bedstead so as to afford the above-noted advantages to an increased degree and so as to afford means of supporting a transversely extending means of supoprt for various appliances that may be of use to the occupant of the bed.

A further object is to devise a particular form of device for attaching the side rails to the bedstead in a comparatively simple and expeditious and yet most effective manner so as to increase the dependability of the device.

A still further object is to devise such an assembly that possesses an attractive appearance insofar as the rail-attaching means is concerned.

Other objects will appear from the following description and claims when considered together with the accompanying drawing.

- Fig. 1 is a perspective view illustrating. our device applied to a bedstead;

Fig. 2 is an enlarged partial view of a clamping member in side elevation; Fig. 3 is another view of a clamping member in elevation at ninety degrees to Fig. 2; Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 3;

Fig. 5 is an enlarged sectional View of the cross bar, with the inverted U-shaped attaching means therefor shown in side elevation; and Fig. 6 is another enlarged view of the structure shown in Fig. 5 but at ninety degrees thereto.

It is to be understood that the present form of disclosure is merely for the purpose of illustration and that there might be devised various modifications thereof without departing from the spirit of our invention as herein set forth and claimed. g

V In the present form of illustration, asshown in the accompanying drawing, the duplicate side rails I and 2 are adapted to extend along the two sides of the bedstead and are of somewhat greater length than the distance between the posts 2 of the bedstead so as to ensure effective engagemerit of the ends of the rails with their supporting means in cases of different lengths of beds.

All of the rail-supporting means, four being here shown, are of duplicate form and each of them comprises a housing of vertically extended substantially channel form with opposite parallel side walls 3 and 4.' The post-clamping lever arms 5 and 6, in each instance, are rockably mounted upon and between the ends of the two parallel cross bars 7 within the housing and have their outer end portions extending out from beneath the notched edges of the side walls 3 and 4 for engagement with opposite sides of the upright post of the bedstead. The notches 3a and do will permit engagement of the edges of the walls 3 and 4 with the post of the bedstead. The outer portions of the lever arms 5 and B are 'of curved form corresponding to the curvature of the surface of the bed post and may have their inner curved surfaces faced with rubber 5a and 6a or other suitable material for increasing the frictional engagement with the post of the bedstead. The inner end portions of the lever arms 5 and 6 extend substantially parallel with the side walls 3 and 4 of thehousing and have their rear end portions bent inwardly, as indicated at 52) and 6b. The arms 5 and 6 at their rear end portions are sufficiently spaced to accommodate the lesser dimension of the oblong wedge-like member 8 which has its longer sides beveled for non-rotatable engagement with the portions 5?) and 6b and is thus adapted for Wedge-like action thereupon and therebetween so as to rockthe lever arms 5 and 6 upon their pivots in effecting operative engagement of the same with the post of the bedstead. The oblong wedge-like member 8 is in the form of a screw-threaded nut and is mounted upon the screw member 9 which, in 1 .turn, is extended freely through the rear wall of the housing so as to be rotatable therein; and. the member 8 is longer than the distance between the rear end portions of the members 3 and 4 so as to prevent turning of the member 8 with the ment of the member 8 between the ends of thev arms 5 and 6 so as to thereby rock the same about their pivots and effect clamping engagement of thecurved outer portions thereof with the opposite surface portions of the bed post. At the same time, the engagement of the head of the member 9 with the rear wall of the housing, will also serve as a means of effecting engagement of the free edge portions ofthe side walls 3 and 4 with the post of the bedstead so as to thereby still further afford frictional engagement of the device with the post. Thus there will be imposed opposite forces upon the portions 5b and 6b and'the rear wall of the housing, that is outwardly by the wedge-like member 8 and inwardly by the head of the member 9, respectively. By turning the screw member 9 in the opposite direction, the lever arms 5 and 6 may be released from engagement with the post of the bedstead and the device may then be either raised or lowered to another position upon the post and then secured in such new position or the entire device may be removed.

The side rails I and 2 have their ends extending through holes in the upper end portions of the side walls 3 and 4 of their respective clamping members and are secured insuch position by means of the set screws I0. By having our particular form of clamping member with its Opposite parallel sides, the rail in each instance is afforded effective bearing or supporting engagement as the rail, in each instance, extends through registering holes in the side Walls 3 and 4. Also, thisdevice may be employed upon beds of different lengths by virtue of the adjustment allowed by the set screws I0.

By having the clamping member of such upright extent, as herein indicated, and with the clamping'means per se located at the lower end thereof, it may be set at an extreme position at the upper part of the post of a bedstead while still being able to clamp in an effective and dependable manner. That is to say, our attaching means may have effective clamping engagement at the lower part thereof while the side rail is attached to the upper part thereof; and, as a result, the side rail may be positioned at a point corresponding at least with the very top of the bedstead.

We have provided also a transversely extending rail I I' which is adapted to be attached to the side rails I and 2 in any position therealong. For this purpose, the inverted U shaped members I2 and I3 of duplicate form, each has registering holes in the lower parts of the parallel sides thereof so that the same may be placed upon the" side rails the transverse rail II into such binding engage ment. This rail II may serve various purposes; as for instance it may support a tray'by means of the suspension rods with hooks at the upper ends thereof for engagement over the rail I I or, without the tray, this transverse rail may be used by the occupant of the bed as a means of exercise or for raising himself in the bed.

Other advantages will suggest themselves to those who are. familiar with the art to whichthis invention relates.
