Application filed September 10, 192. Serial No. 218,620.

This invention relates to beds, and particularly to beds of the type having enclosed sides.

The invention aims to improve the frame construction of such beds in order to render them more sturdy and rigid while preserving an economical constructionf T he invention includes an arrangement whereby one of the sides of the bed may be errn peditiously lowered on sliding rails, and embraces also a foot operated latch for maintaining the sliding section in raised position. While a preferred embodiment has been disclosed for purposes of illustration, it should be understood that various changes may be made in the structure without departing from the spirit and scope of the invention as hereinafter set forth and claimed.

In the drawings; 29 1 is a side elevation of a bed embodying the invention.

Fig. 2 is an end elevation of the bed.

3 is a side elevation of the rear part of the bed.

1 is an enlarged sectional detail. Fig. 5 is a view-similar to Fig. 4 but showing the parts in a different position.

Fig. 6 is a section on line 66 of Fig. 2. Fig. 7 is an enlarged perspective of a part so of the latch.

g. 8 is an enlarged perspective of part of the latch-operating mechanism.

Fig. 9 is a plan of the hook-carrying end piece. v 5 Referring to the drawings morespecifically,

the bed comprises a spring ed by a head section 11 and a foot'section 12. The spring frame is formed of side rails 13 of angle iron, which are joined at their ends by rails 1 1.

The side rails carry at each extremity a cast hook-piece 15 of the shape illustrated in Fig. 9. Each of these hook-pieces is formed with a hook 16 which is adapted to project beyond the end of the spring frame and engage over one of the transverse rods 17 carried by the head and foot sections. The hook piecesare also provided with transverse lugs 18 at their upper and lower edges, these alga being to engage corner posts frame 10 support- 19 of the'head and foot sections to brace these sections a ainst lateral movement.

When the bed is to be used as a crib it is provided with a vertically movable front section 20 as shown in Fig. 1. The top and bottom rails of this front section have their ends formed with cars 21 which slide over guide rods 22 attached to the corner posts 19. A latch mechanism is provided for holding the front section in raised position, and the latch is connected with a foot lever 23' in such a manner that operation of the foot lever will permit the front section to be lowered.

The latch mechanism will now be described. Referring to Fig. 9 it will be noticed that each end piece 15 is formed with an inverted T slot 2 1 near its loweredge, leaving a round bar 25 below the slot. The latch bar 26, which is of the shape shown in Fig. 7, has its lower end 27 curved to fit around the bar 25 and carries a lug 28 adapted to extend through the stem of the T slot 2 1. A concave groove 29, formed in the forward face of the latch bar, fits around the guide rod 22 when the parts are in the latched position of Fig. 1. One of the cars 21 then fits over the top of the latch bar and due to the shape and angular position of the latch bar, the front section is held against downward movement. A coiled spring 80 fits over the lug 28 and has one end pressing against the hook-piece 15 while its other end is anchored in a hole 31 formed in lug 28. Due to this mounting the spring normally tends to press the latch bar away from guide rod 22 to the unlatched position of Fig. 5.

The latch bars 26 are moved to latching position by the following mechanism: The operating members 32, shown in Fig. 8, comprise cruciform shanks 33 which merge into fiat portions 34ccarrying end segments 35. These operating members are pivoted to the end rails by bolts 36 passing through apertures 37 in segments 35, and their shanks are connected by a square tube 38 to cause them to rotate in unison. A tension spring 39 has one ent hooked in a hole 1O formed near the upper edge of flat portion 34, the opposite end of the springbeing suitably attached to the end rail 14. 1 spring normally tends to turn the 1 member in a mastersleek vise d1-=' rection so that the lower part of the portion 34 engages the lug 28 to press latch bar 26 to ward the rod 22 as in Fig. 4.

The upper end of foot lever 23 is pivoted to the segment 35 at 41, so that downward pressure on the foot lever will rock the operating members in a Clockwise direction to the position of Fig. 5, permitting spring 30 to move the latch bar away from the guide rod when the front section has been raised to disengage ear 21 from the upper end of the latch bar.

The rear side of the bed is closed by a section 42 which may be removed when desired, but is not adapted to be lowered in a manner similar to the front section. The top rail 43 of this rear section carries at each end a depending forked wedge lug it. which fits over a pin l5 mounted on the end frame. The end ,uprights 46 of the rear section project through holes formed in the upper surface of hook piece 15, thereby preventing lateral movement of the rear section.

The movable front section is normally in the raised position shown in 1, and is held in that position by the latch bars 26 in the manner indicated in Fig. 4:. When it is desired to lower the front section it is first slightly raised to disengage ears 21 from the upper ends of the latch bars, and the foot lever 23isthen depressed to rock the operating members to the position of 5 and permit the spring 30 to move the latch bar to the unlatched position. The front section may now be lowered, and springs l7 coiled about the lower ends of guide rods 22 will softly cushion its descent.

It will be clear from the above disclosure that applicants device provides a perfected safety latch for the movable section since it is impossible for the occupant of the bed to lower the movable section, and it is also impossible to lower the front by accidental tripping of the foot lever. To accomplish this action it is necessary to first raise the front section and hold it elevated wh le the foot lever is depressed to release the latch.

I claim: v

1. A bed comprising frame members, end sections, vertical guide rails carried by the end sections, a front section having ears riding along the guide rails, a latch bar pivotally mounted on one of the frame members and adapted to contact with a guide rail under one of the aforesaid ears to maintain the front section in elevated position, a spring normally biasing the latch bar away from the guide rail, and a foot-controlled operating member adapted to control movements of the latch bar.

2. A bed comprising frame members, end sections, vertical guide rails carried by the end sections, a front section having ears riding along the guide rails, a latch bar pivotally mounted on one of the frame members and adapted to contact with a guide rod and to extend into one of the aforesaid ears to maintain the front section in elevated position, a spring normally biasing the latch bar away from the guide rail, a pivoted operating member for moving the latch bar toward the guide rail, a spring normally biasing the end sections, a front section having ears riding along the guide rails, a latch engaging an ear of the front section for mamtamg sald section in elevated position. a lever for operating the latch, the engaged front section ear normally fitting over the latch to prevcn" 'nlatching until after the front section has been raised. 7
