COLLAPSIBLE BED STRUCTURE. A

Specification of Letters Patent. Patented Apr. 12, 1921.

Application filed J'nly 21, 19.19. Serial No. 313,103.

and useful Improvements in Collapsible Bed Structures and the like, of which the following is a specification.

rlhis invention relates to beds'and the main object is to provide a collapsible bed of a character capable of being readily transported in compact form in an automobile or other vehicle and supported for use either on or apart from the vehicle, together with means for supporting a tent or covering of suit able and ample dimensions over the bed.

An object is to provide a structure which has sectional side and end rails, and legs which are adapted to be quickly and easily assembled together for use and when so assembled may be held sufficiently rigid to insure the comfort and safety of the occuant.

p A further object is to provide a bed of the character referred to in which the bed proper, or springs, may be adjustably supported for increasing or decreasing the tension thereof according to the weight of the occupants, thus providing resiliency in the springs in desired degrees and rigidity in the supporting frame.

A further object is to provide a bed structure which by the duplication of some of the main parts may be utilized for forming a multiple bed tent capable of use for housing and serving an entire family, the entire structure being readilyv assembled and disassembled as in the case of a single bed and carried in compact form on a vehicle. Other objects may appear as the description progresses.

I accomplish the above objects by means of the structure illustrated in the accompanying drawings, forming a part of this application, in which similar characters of reference are employed for indicating the same or like parts. In said drawings:

Figure 1 is a perspective view of a single bed in which my improvements are shown.

Fig. 2 is an enlarged section of the same,

taken longitudinally of the bed.

Figs. 3 and 3a are perspective views of different forms of corner connectors for holding the members of the bed together.

Fig. 4 is a perspective view of a combined bed and tent in which the' structure shown 1n Fig. 1 is employed'.

Fig. 5 is a plan of a multiple bed arrangement in which the parts of Fig. 1, are duplicate and slightly rearranged for providing four beds symmetrically arranged about a common point.

Fig. 6 is a perspective view of a combined bed and tent of the form and character shown in Fig. 5.

In the consideration of this invention, reference 1s had to my former application Y for bed structures, Vliled April 18, 1919, Serial Number 292,490.

For campingpurposes especially, a bed structure should be collapsible and composed of as few parts as will be consistent with comfort, safety and convenience, and'to this end I have provided a structure which has the features mentioned and at the Sametime l is as comfortable as a permanent bed and may be transported on an automobile running board in a compact package and vvery quickly assembled and disassembled. y

Such a structure is shown clearly in Fig. 1, and `includes side rails S, S, each comprising a pair of tubular members 1,1, the adjacent and abutting ends of which are vslidable in a telescoping tube 2, and the` outer ends of said members 1, 1, are fitted over stems 3, 3, of a special form of corner connector, or

fitting, C. rFhe end rails E, E, are prefer-v ably- 4of angle irons 1, 4, and one side of each of said angle irons at each end "is bent to form a socket 5 to receive the right angle stems 6, 6, of the corner fittings C.

Legs L,`L, etc., of suitable length, also of tubular formation areprovided for attachment to the corner fittings C, C, and the upper ends of said legs are fitted over the depending stems 7, 7 of said fittings. The

legs at one end' of the bed maybe shorter than the. legs at the other end so that the one end may be supported on the running board of an automobile while the opposite end restsy upon the ground. It will be observed that in Fig. 3, the lower stem 7 of the corner fitting C, is pointed so that the same may be driven into the ground and one of these fittings may be placed at the` lower ends of the legs L, with the vertical stems 8 thereof inserted in the legs, thus preventing the movement Vo f the legs and insuring rigidity 0f the structure. When the bed is partially held on the Vehicle running board, as stated, the stems 7, of the j fittings C, may be inserted in suitable holes in the running board so as to hold the bed thereon. 'Y Y The fittings C, may have two, three, four, five or siX of the stems thereon, as necessary, and the central portion 9 thereof is cubical in form and the sides ofthe cube serve as abutments against which the tubular frame members are held.

A spring mattress M, composed of linked wires l() and coil springs 1l is suspended between thel end rail E, of the head ofthe bed and an intermediate rail I, which eX- tends transversely of the structurenear the foot of the bed, rail l, being connected with the foot rail E, by means of a .pair of bolts B, the heads l2 of which rest against'the web of the angle iron rail I, and the bolts eX- tendingthrough the end rail E, and having nuts ldthereon with handles lll, by means of which the nuts may be turned on the bolts for increasing or decreasing the tension of the mattress M. `Said mattress thus serves to hold the structure together for use when lheld in tension as described.

The head and foot of the bed have vertical tubular members 15, extending'substantially above the level of the mattress M and their lower ends telescope the vertical stems 8 of the fittings C. while their upper ends are open to vreceive the bentends 17 of transverse head and foot rails ll and F. Y

A tent, or suitable cover, t, as shown in Fig. l may be supported on the head and foot rails H and F, by means of oppositely inclined tubular rafter rails 18 held in Ts 19 on the railsH and and connected at their adjacent ends by means of the conneet-ors 20, each set of rafter tubes l8-l8, being connected transversely of the Vstructure by means of ridge tubes 2l, thus forming a'slreleton frame for the tent, the ridge of which is in the center of the bed. In such a tent, the ends and sides ofV the tent t, may be extended only to the level of the end and side rails, as shown in el., or to the ground, if de'sira "le, and the lower edges of the tent tied to the frame at suitable points` ln thev form of structure shown in Figs. 5 and 6, the members i8 and 2l, are eliminated and one corner of the head of the bed is built up or extended for a center pole for the tent t, the four beds being symmetrically Y arranged around the center pole with the end and side members arranged as shown and connected by means of the fittings C, Cords 22, may be extended from; the top of Vthe centervpole 23 to one of the foot corners Vof each of the beds, as indicated 1n broken lines in Fig. G, and from thence extended to the ground and stalred in the usual manner, as shown. -Partition curtains 24C, may also be .suspended from the top of the tent and attached to the bed structure so as to divide the interior of the tent'into separateV bed compartments, and each of the-compartments may have a separate entrance opening as shown for one of the compartments in Fig. 6. Y

lt will be understood that the same struce is employed for the structure shown in lugs. l and 6, but that a multiplicity of parts is required for the latter, while only a relatively few parts are necessary for the former structure. ln other words, a complete equipment may include all the parts necessary for the multiple bed tent shown in Fig. 6, and one or more of the single bed tents may be formed of the same elements ,sed in the larger structure. f

WhenY collapsed, the various parts are grouped and placed in parallel positions, the spring mattress liti is folded into compact form, and all of the parts may thenbe rolled into a relatively small package with the tent used as a wrapper for the parts, though a bag maybe provided for inclosing` and holding all of the parts' if desirable.

.The form of iittingshown in llig. 3 is especially adaptable for a multiple bed structure as extra legs and connections may be provided at intervals for reinforcing the bed structure where the joints are made,and where a tent is not used, as for instance on a screen perch, two or more beds may beA grouped into parallel positions and con nected together, thus reducing the num-ber of parts required.A for assembling an equal number of separate beds.

`W hat l claim is:

l. A canopy bed structure including-end rails of ln-shaped cross section, siderails for spacing said endv rails, connectors at the corners for holding said sine rails together, said end rails having sockets formed in the vincluded angle between the sides, and said other arms projecting transversely into thev sockets of said end rails, other arms projecting downwarcly therefrom, legs having sockets the upper ends thereof, telescopically fitting said arms, other arms project# ingr upwardly therefrom, and head and foot members having soclrets engaging said last mentioned arms.

lcrligned at Los Angeles, Los YAngeles county, California, this 26th day of June,
