Hospital bed with pivoting side rail

Abstract

The hospital bed with pivoting side rail includes a bed frame having a headboard, a footboard and a platform mounted thereon. The side rail has an upper end, a lower end, and first and second longitudinally opposed sides. The lower end of the side rail is pivotally attached to the bed frame, and the upper end of the side rail is releasably attached to the headboard and the footboard. In order to safely and easily deploy and collapse the side rail, first and second adjustable struts are provided, the struts having opposed first and second ends, such that the first ends of the first and second adjustable struts are pivotally attached to the first and second sides of the side rail, and the second ends of the first and second adjustable struts are pivotally secured to the headboard and footboard, respectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(4) The hospital bed with pivoting side rail, designated generally as 10 in the drawings, is a hospital bed or other patient bed suitable for a health care facility having a side rail 18 that can be selectively pivoted from a fully upright position (as shown in FIG. 1) into a position which is substantially parallel to the bed frame, as shown in FIG. 2. In the fully deployed position of FIG. 2, side rail 18 forms a shelf or table-like extension for moving a patient in the bed 10 during a change of the bed's sheets. As best seen in FIG. 2, the bed frame includes a rectangular frame and has a headboard 12 and a footboard 14 mounted at opposite ends of the rectangular frame, and a platform 16 mounted on the rectangular frame. It should be understood that the headboard 12, the footboard 14, the platform 16 and the side rail 18 are shown for exemplary purposes only, and may have any suitable overall shape, style and relative dimensions. It will be further understood that the hospital bed 10 shown in the drawings is mounted on hydraulic lift cylinders hidden below the platform (see, e.g., FIG. 2 of International Patent Application PCT/JP2017/019707, published as WO 2018/003367, which is hereby incorporated by reference in its entirety) that may raise the bed frame to a desired height, but the frame of the hospital bed 10 may be mounted on any desired legs or posts at any desired height. Further, although only the pivoting of side rail 18 is described below, it should be understood that side rail 20 may also be operated in an identical manner or, alternatively, side rail 20 may be a conventional side rail.

(5) Side rail 18 has an upper end 22, a lower end 24, and first and second longitudinally opposed sides 26, 28, respectively. The lower end 24 of the side rail 18 is pivotally attached to a perimeter rail of the bed frame by hinges 30 or the like. It should be understood that hinges 30 are shown for exemplary purposes only, and that any suitable form of pivotal attachment may be used. The upper end 22 of the side rail 18 is releasably attached to the headboard 12 and the footboard 14, respectively. It should be understood that the upper end 22 of the side rail 18 may be releasably attached to the headboard 12 and the footboard 14 using any suitable type or number of locking mechanisms or other releasable attachments. In FIGS. 1 and 2, locking mechanisms 44, 46 are shown including brackets extending from the headboard 12 and footboard 14, respectively, each having a slot 48, 50, respectively, for receiving a corresponding hook 52, 54, respectively, attached to the upper end 22 of side rail 18. The locking mechanisms 44, 46 and the corresponding hooks 52, 54 provide a releasable lock similar to that found in car trunks, for example, although, as noted above, it should be understood that the upper end 22 of the side rail 18 may be releasably attached to the headboard 12 and footboard 14, respectively, using any suitable type or number of locking mechanisms or other releasable attachments.

(6) In order to safely and easily deploy and collapse the side rail 18, first and second adjustable struts 32, 34, respectively, are provided, which may be in the form of telescopic tubes, gas struts (also commonly referred to as gas springs), hydraulic dampers or the like. First ends 36, 40 of the first and second adjustable struts 32, 34, respectively, are pivotally attached to the first and second sides 26, 28, respectively, of the side rail 18. Second ends 38, 42 of the first and second adjustable struts 32, 34, are pivotally attached to the headboard 12 and footboard 14, respectively.

(7) When the side rail 18 is fully deployed, as shown in FIG. 2, each of the first and second adjustable struts 32, 34 is extended to a maximum length, which corresponds to the side rail 18 being oriented parallel to the platform 16 mounted on the bed frame 11. Thus, the first and second adjustable struts 32, 34 prevent the side rail 18 from being angled downward from the horizontal plane, preventing the patient from accidentally falling out of the bed 10. The first and second adjustable struts 32, 34 also ease and regulate the collapse and deployment of the side rail 18 so that it is not performed in a manner that would startle or potentially injure the patient.

(8) It is to be understood that the hospital bed with pivoting side rail is not limited to the specific embodiments described above, but encompasses any and all embodiments within the scope of the generic language of the following claims enabled by the embodiments described herein, or otherwise shown in the drawings or described above in terms sufficient to enable one of ordinary skill in the art to make and use the claimed subject matter.
