Application October 4, 1954, Serial No. 460,029
7 Claims. (Cl. 5-331) This invention relates to a guard gate for beds and has as its primary object the provision of a gate which may be detachably applied to the side rail of a bed frame and when applied be readily disposed in either an upwardly extending operative position or in a downwardly extending out of use position.
Another object is to provide an adjustable bed gate together with a mounting therefor in which the mounting is adapted to be detachably secured to either or both of the side rails of a bed frame, and which will not damage the frame to which it is attached.
A further object is to provide a construction whereby the guard gate may be easily and rapidly attached to and removed from its mounting.
With the foregoing objects in view together with such other objects and advantages as may subsequently appear, the invention resides in the parts and in the combination, construction and arrangement of parts hereinafter described and claimed, and illustrated by way of example in the accompanying drawings, in which:

Referring to the drawings more specifically AA indicate the parallel side rails of a bed-frame here shown as formed of angle iron comprising a vertical web portion a and a horizontal webportion b extending inwardly 2,817,854 Patented Dec. 31, 1957 from the upper margin of the web a. The side rails AA afford a mounting for a bed-spring assemblage and are supported in the manner common in bed construction.
In carrying out the invention either one or both of the rails AA is fitted with an outwardly opening horizontally extending socket member 14 which in the construction shown in Figs. 1 to 8 inclusive comprises a cylindrical tube the outer open end of which extends through and is afiixed to a supporting plate 15 having an inturned flange 16 on its upper margin. The plate 15 when mounted is positioned against the outer face of the web a of a rail A with the flange 16 seating on the web b as shown in Fig. 2. g
The socket supporting plate 15 is designed to be removably clamped on the rail A at any suitable point along the length thereof, which is accomplished by a clamping plate 17 positioned against the inner face of the web a with the lower marginal portion thereof projecting below the lower margin of the web a and connected to the plate 15 by a pair of bolts 1818 which are passed through the plate 17 from the inner side thereof and screwed into engagement with internally threaded holes 1919 in the plate 15 so as to tightly clamp the plates 1517 against the opposite sides of the web a. When the plates 15-17 are thus positioned the socket member 14 on the plate 15 will extend beneath the side rail A transversely thereof.
As a means for facilitating the mounting of a pair of the socket members 14 on a pair of the rails AA so as to be positioned in axial alignment on opposite sides of a bed, the socket members are afiixed at their inner end portions to tubes 20-20 in overlying relation thereto which tubes are telescoped with a sliding fit, as shown in Fig. 4- and are slidable relative to each other, the tubes 20-20 being thus interconnected to permit of their longitudinal adjustment to enable mounting of the socket member and tube assemblage on bed frames of various widths.
As shown in Figs. 1 to 4 the tubular socket member 14 serves as a mounting for a gate B here shown as comprising a rigid frame structure formed of metallic tubing embodying a top rail 0, a bottom rail d, end rails e and f,
and a series of spaced intermediate vertically extending rails g connected at their upper and lower end to the top and bottom rail c-d.
Mounted on the frame member B and attached to the bottom rail d and to a pair of rails g is a flat abutment plate 21 extending parallel with the inner side of the gated From the lower portion of the plate 21 fixedly' projects a cylindrical trunnion 22 which is adapted to be inserted in the open outer end of the socket member 14 in slidable contact therewith to afford a pivotal mounting for the gate B on which the latter may be turned to an upwardly extending position relative to the bed frame A, as shown in Figs. 1 and 4, or be disposed in a dependent position as indicated in dotted lines in Fig. 4.
When the gate B is thus mounted the plate 21 thereon slidably abuts the outer face of the plate 15'. As a means for releasably retaining the trunnion 22 in the socket 14 the latter is equipped with a spring pressed detent C which embodies a tubular housing h mounted on the socket member 14 perpendicular thereto, in which housing is mounted a reciprocal stem i the inner end of which is fitted with a domed latch j which normally projects interiorly of the socket 14 under the urge of a spring k which bears between the latch j and an abutment l in the form of a screw mounted in the wall of the housing h. The latch j is engageable with a circumferential channel m formed on the trunnion 22 at a point on the latter where it will align with the latch i when the trunnion 3 i is in its innermost position in the socket 14. The outer end of the stem i is fitted with a head 23 constituting a finger hold adapted to be grasped and pulled to elfect retraction of the latch j outof engagement with the channel m when it is desired to withdraw the trunnion 22 out of engagement with the socket 14.
As a means for retaining the gate B in its upwardly projecting operative position the gate is equipped with a spring pressed detent D corresponding to the detent C and which requires no further description since the parts of the detents C and D are identical. The housing of the detent D is mounted on the bottom rail d of the gate with the inner end of the housing opening through the guide plate 21 so that the latch i will normally be positioned for engagement with an opening or recess 24 formed in the plate 15 at such point that when engaged with the latch of the detent D the gate B will be held against movement in an upwardly extending position. When it is desired to dispose the gate B in its dependent inoperative position, the latch of the detent D is retracted out of engagement with the recess or opening '24 whereupon the gate may be swung on its trunnion to a dependentjposition thereon.
Manifestly a gate B may be mounted on either or both side rails of a bed frame and when a gate isjprovided on each side rail, that is on each of the opposite sides of a bed, either of the gates may be operated and removed and replaced independently of the other.
In the form of the invention shown in Figs. 9 to 12 inclusive, a gate E fashioned in a manner similar to the previously described gate 13 is mounted for vertical reciprocal movement on the bed rail so that it may be disposed in an upwardly projecting position relative to the rail or in a downwardly extending or dependent position relative thereto. In this instance a pair of clamping plates 24 and i 25 are clamped on opposite sides of dependent web a of the bed rail A by means of bolts 26 which connect the plates 24 and 25 beneath the web a, as particularly shown in Fig. 10. A flange 27 on the upper end of the plate 24 seats on the web b of the bed rail to support the clamping plates against downward displacement. In this instance the plate 24 is fitted with a socket member 28 of rectangular cross section which opens at one end through the plate 24 and projects from the inner side thereof. The rectangular socket 28 is designed slidably to receive in telescopic engagement therewith a stud 29 of rectangular cross section fixedly mounted on a guide plate 30 adapted to be seated against the outer face of the plate 24. The stud 29 when positioned in the socket member 28 is detachably engaged by the latch l of a spring pressed detent F which latch is arranged to engage a hole or recess q in the stud 29, the detent F corresponding to the detents C and D.
Mounted on the outer face of the plate 30 are laterally spaced pairs of vertically spaced grooved rollers rs and tu of which the rollers of each pair are laterally offset relative to each other. The upper rollers r--t of the pairs of rollers abut the opposite sides of a pair of parallel vertically extending rails gg' of the gate E while the lower and innermost rollers s-u abut the adjacent sides of said rails thus forming a rolling guideway in which the rails. g-g' are supported for vertical movement.
A spring pressed detent G is mounted on the lower rail of d of the gate E, the latch l of which is detachably engageable with an opening or recess. 31 in the plate 30 arranged to receive the latch when thegate E is in its elevated position whereby the gate will be held in such position- On retracting the latch I out of engagement with the plate 30 the gate may be lowered on its roller guideway to. its dependent positionindicated in dotted lines in Fig. 12..
The invention is particularly designed for use on hospital' beds where it is desired to equip the bed with a guard gate extending along only a portion of the length of the bed such as its upper half, and where it is necessary to mount the gate so that it may be readily disposed in either its upwardly extended operative position or its dependent out of the way position, as well as being subject to removal from the bed by detaching the gate from its mounting without removing the latter which removal of the gate is sometimes necessary in order to permit passing the bed through a doorway.
