Claims.

This invention relates to articles of furniture, such as lounges, cots, chairs and the like, which have a section or part which is adapted to be swung or adjusted to different positions with respect to an adjacent section of the article, and a device for holding the movable section in adjusted position. In this application, the holding device is disclosed as applied in a lounge for holding the hinged back of the lounge in different desired positions, but it will be understood that the device is adapted for use in other articles of furniture for holding an adjustable section in desired adjustments.

One object of the invention is to provide a desirable, practical device of novel constructionl for holding the adjustable section in a desired position, and which is operated to hold and release the section simply by movement or manipulation of the section itself without the necessity for separately operating the holding device.

Other objects of the invention are to provide a holding device of the type mentioned, which is simple and inexpensive but strong, and durable and reliable in action; which enables the ready assembly of the parts by an unskilled person, but the parts of which, when assembled, are prevented from unintentional disarrangement.

Further objects and advantages of the invention will appear from the following specication of the preferred embodiment of the invention, shown in the accompanying drawings, and the novel features of the invention are set forth in the appended claims.

In said drawings:

Fig. 1 is a side elevation of a cot or lounge embodying the invention, showing the back section in extended horizontal position.

Fig. 2 is a fragmentary plan View, partly in section, thereof.

Fig. 3 is a side elevation thereof showing the back section held in a raised position.

Fig. 4 is an enlarged side elevation of the holding device for the back section, showing the same position of the parts as Fig. 3.

Figs. 5 and 6 are similar views showing different positions of the parts assumed in the releasing action of the device.

Fig. 7 is a sectional elevation of the device on line '1 -1, Fig. 4.

Fig. 8 is a sectional elevation on line 8-8, Fig. 4, showing the brace in position for removing it from the guide.

As illustrated in the drawings, the holding device is applied to a cot, comprising a seat or bottom section I0 and a back ysection II, which is suitably hinged to the seat section to adapt the back to occupy a horizontal position in line with the seat section, so that a person can lie at full length on the cot, or to be swung upwardly and supported in a more or less standing position, so as to provide a back support for a person in a more or less sitting or reclining position on the cot. As shown, the seat section has a U-shaped angle bar frame I2 which supports a bottom fabric I3 of link or other suitable construction, and the back section is of similar construction, having a U-shaped angle bar frame I4 to which the bottom fabric is attached. The side bars of the back section are hinged or pivoted in any suitable manner at I5 to the adjacent ends of the side bars of the seat section. As shown, the cot is provided with supporting members comprising a U-shaped leg I6 rigidly secured to the seat section, near its head end, and equipped with ground wheels I'I on which the cot can be wheeled about; a U-shaped leg I8 hinged to the foot end of the seat section and a U-shaped leg I9 hinged to the outer end portion of the back section. The leg I9 on the back section is connected by a link 20 to the stationary leg I6 so that when the back is raised, its leg I9 will be folded in toward the back, and when the back section is lowered to a horizontal position, its leg will be swung out and held in position for supporting the back section. The hinged leg I8 at the foot end of the cot is also adapted to be folded from its supporting position up under the seat section, and is adapted to be held in its supporting position by bearing Aagainst stationary abutmentsl 2i on the seat frame. The cot or article could be of other construction having a hinged or adjustable section.

Braces or arms 22 are preferably provided at opposite sides ofthe cot, each suitably pivoted at 23 at one end to the adjacent side bar of the back section and having its opposite or front end arranged to cooperate with a holding device on the seat section, whereby the brace is held for supporting the back section in a standing or rearwardly inclined position, or is released to permit the back section to swing down to its horizontal position. The braces are Shown as made of metal tubing and having downwardly curved, front end portions, and when the braces are in posi* tion for holding the back in its standing position, they form arm rests. The brace and its holding device are duplicated at opposite sides of the cot to hold the back more rmly, but a single brace and holding device only could be used, and

since the two devices are alike, only one is hereinafter described in detail.

The front end of the brace extends and is adapted to slide or move between the adjacent side bar of the frame I2 and a guide bar or member which, as shown, has offset end portions stationarily secured, as by rivets, to the frame side bar so as to space the body portion of the guide member away from the frame bar, thus providing the necessary space or slot between these parts for the reception and movement of the end brace.

A stud or projection 21 fixed or formed on the front end portion of the brace, projects laterally therefrom over and is adapted to slide on the upper edge of the guide member 25, which edge is provided with one or more notches into which the stud is adapted to drop and engage one end of the notch for holding the back section in araised position. Two notches 28 and 29 are f shown in the guide member and, by engaging.` the stud in one notch, the back section is heldin oneV position, while by engaging the stud in the second notch, the back section is heldin a different adjustment. As shown, each notch isprovided with an abrupt rear end or shoulder 36 which is preferably undercut or of hook form to prevent unintentional disengagement of ther stud from the notch with consequent unintentional falling of the back from its raised position. The front edge 3i of the first or rear notch slopes upwardly and forwardly soA as to permit the brace stud to ride on this edge upwardly out of the notch onto the upper edge of the guide, by a forward movement of the brace. back sect-ion in raised position, it isvvonly necessary to lift it, which causes the study on the brace to slide forwardly on the guide runtil it reaches the first notch 2B, when it will drop into this notch, and by engaging'the end 3G, hold the back sectionrup. If it is desiredto adjust the back section further forwardly, it is onlynecessary'to move it forwardly and the brace stud willride up out of the nrst notch and drop into the next notch and thus hold the back' section' in the second adjustment, shown in Fig. '3'. I

For releasing the brace to permit the lowering of the baci: section rearwardly from its raised positiomthe foremost notch 29 is lengthened or extended. forwardly and a movable releasing member 32 is provided, which is preferably pivoted atV 33 onrthe guide member to swing forwardly and rearwardly. This releasing member, as shown, is provided with alateral lug 34' on its lower end adapted to engage'the lower edge of the-guide for retaining the releasing member in either a forwardly or rearwardly inclined: position, shown in Figs. .5y and 6, and.7 the releasing member is shaped to provide a lug 35- at its'upper, rear end portion and an edge 355,. which curves or slopes downwardly and forwardly from this lug.

When the back is in. its foremost, raisedadn justment, the brace stud will be engaged inthe foremost notch 29 back of the releasing. member 32, which then occupies the upwardly andforwardly inclined position shown in- Figs. Sand 4. Then, when. it is desired toy release and lower the back section, it is only necessary to move the back section further forwardly and the brace stud will ride up on the inclinedrear edge ofthe releasingy member and drop downY into thefn-otch in front of the lug 35 on the upper en'dfofthe releasing member. Then, by pullingfthe 'back section rearwardly,'the brace stud will engage To secure the the lug 35 and swing the releasing member rearwardly and, in so doing, will ride on the curved edge 36 of the releasing member up out of the front notch. In its rearwardly inclined position, the upper end of the releasing member, as shown in Fig. 6, will substantially bridge the open, upper end of the first or rear notch 28, so that in the continued rearward or lowering movement of the back, the brace stud will ride over the' rear notch on the releasing member and pass on to the upper edge of the guide in rear of the rear notch. When the back section is again lifted and supported in a raised position, the brace stud 2l in its forward movement on the upper edge of the guide will engage the upper end of the releasing member, which then inclines rearwardly, and will shove the releasing member forwardly to permit the 'stud to enter the rear notch. If, in this movement of the brace stud to enter the rear notch, it does not shove the releasing device forwardly far enough to drop into its forwardly inclined position, further` forward movement of the stud for releasing'it to permit the lowering of the back will shove the releasing member forward to its .forwardly inclined position.

Thus, the back` can be raised and secured in either of two standing or raised positions, simply bylifting and moving the back to the desired raised adjustment,and` then the back can be released and lowered fromv either adjustment, simply' by -rst a forward and then a rearward movement of the backL section, and without first or separately manipulating the holding device to release the braceand permit the lowering of the back.v section. When only a single raised adjustment of the backA is required, it will be understoodA that only the single, `long notch 29 with the releasing member is necessary.

Asv shown in thegdrawings, the front end of eachA brace is bent inwardly, or provided with an inwardly extending projection i6 which is adapt edI to extend under the lower edge of the adjacent side bar of the seat frame l2 to' prevent unintentional disengagement of the end of the brace from its guide slot between the guide mem.. ber and the frame-bar. Inv order to permit the insertion of the front end' of the brace into the guide slot between the guidefbar and the frame bar, in assembling the parts of the cot, the guide bar, 2-5 is provided with arear end portion 4| which offset outwardly from` the `frame bar, far enough to permit the 'laterally extending end of the,- brace to pass through they passage 42 thus formed between the guide bar and frame bar, as

illustrated in Fig. 8. In the normal operation of the device, afterthev assembly `of therpa'rts, the frontend oftheY brace does not move rearwardly far enough to lbecome: disengaged through the wide passage 42.
