UNITED STATES FREDERICK L. ACKERMAN, OF PUEBLO, COLORADO.

FOLDING TENT FRAIYIE.

Application filed March 27 1926. Serial No. 98,015.

My invention relates to folding tent frames, and particularly to a frame adapted foruse with a tent of the beachor umbrella type.

An object of my invention is to provide a collapsible supporting frame which eliminates the objectionable center poles or other supporting or bracing members in the middle of the tent, thus afiording space of the full size of the tent entirely unobstructed by a center post or other support.

A'further objectis to so construct the supporting frame that all units, while collapsible to permit compact folding of the various parts, are permanently connected so that no member can be lost.

Another object is to provide a folding frame which can be erected and taken down with facility, and which is rigid when set up for use in a tent, thus eliminating the necessity of guying from either the top or hips of the tent to prevent the tent from falling down or collapsing accidentally.

A still further object lies in so constructing the tent supporting portions that posi tive adjustment of the parts can be made totighten the roof of the tent regardless of how much the canvas may shrink or stretch. WVith the above and other objects in iew, which will be apparent to those skilled in the art, my invention includes certain novel features of construction and combination of parts which will be set forth in connection with the drawings.

In the drawings 1 Figure 1 is a view in perspective of the tent-with the frame shown indotted lines. Fig. 2 is a similar perspective view, with the tent fabric eliminated, to better show the construction of the frame. Fig. 3 is a top plan-view of the frame illustrating the stretching members in use. Fig. 4 is a fragmentary view showing the mounting of the tent peak supporting pole. Fig. 5 is a detail view illustrating the hinge oint in One of the frame uprights.

Fig. 6 is a fragmentary view illustrating the connection ofone of the frame uprights with the cross bar. I Fig. 7 is a view similar to Fig. 5 showing the connection of the remaining upright with the cross bar.-

The canvas or other fabric l is made up to be of the usual type and form necessary for a tent of the character shown, and popularly known as the umbrella, beach, or pal- 7 positions. lVith metto type of tent. This covering can be provided with any type and number of door and window openings, flaps or the like, and may be made up with or without a sod cloth. At its peak the fabric has a pin opening 2, the pin openings are provided at 3 at each of the corners, these openings being preferably finished with grommets or eyes. The usual loops 4 will be preferably provided at the lower edge of the cover 1 to receive pegs 5 or other fasteners by which the tent is anchored.

The main supporting frame consists of supporting

uprights

6 and 7 connected hingedly at their upper ends to the cross bar 8, and peak pole 9 foldably mounted in the middle of the cross bar. This supporting frame is made of such form and size that the

uprights

6 and 7 will extend parallel with the-fabric 1, on the inner side, along two sides, and the cross bar 8 will extend between the sides at a height corresponding substantially to the hip between the roof and side walls of the tent fabric. The peak pole 9 is made of suflicient length to properly elevate or raise the peak of the roof, and a pin 10 is provided on this peak pole 9 to fit through the opening 2.

Roof spreader members 11 and 12 are pivotally connected with a slide member 13 fitted on the cross bar 8 on one side of the peak pole 9, and these spreader members are provided with

pins

14 and 15 which fit through the openings 3 at adjacent corners of the tent fabric. A similar slide member 16 is fitted on the cross bar on the opposite side of the peak pole 9, and spreader members 17 and 18 pivotally connected with this slide member 16 have

pins

19 and 20 at their ends to fit through the openings 3 at the remaining corners of the roof .hip of the fabric. The cross bar 8 has a plurality of openings 21 formed therethrough on opposite sides of the peak pole 9, and

pins

22 and 23 are fittedthrough these openings to hold the

slides

13 and 16 in adjusted this construction and mounting of the hip or roof spreader frame, the

slides

13 and 16 can be adjusted for the purpose of stretching and tightening the roof of the tent, a positive adjustment and tightening being accomplished regardless of how much the canvas or fabric may shrink or stretch.

As tents of this type are commonly used by campers, automobile tourists, and others who must transport the tent and frame from place to place, it is essential that provision be made to col'apse the frame to be folded into the smallest bundle or space possible.

With this in mind I hingedly connect the

uprights

6 and 7, and the peak pole 9 with the cross bar 8, and provide for the folding of the spreader members when the frame is collapsed. As shown in Figure at, the peak pole 9 has iearing plates 2 f at its lower end pivotally connected at on the cross bar 9. These plates 24 are provided with extensions 26 which fit the cross bar on opposite sides when the peak pole is swung up, alined openings being provided through the extensions to receive pin 27 by which the pole is locked in the upright position. The folded position of the peak hole is indicated by dotted lines.

.In Figure 5 I have shown the folding hinge of one of the upright members. The hinge plates 28 on the lower section of the upright member are provided with ei-ztensions 29 to receive the upper section of the upright member, which is hingedly connected with the lower member at 30. The ring 31 is slidably fitted on the upper member to be moved down to embrace the extensions 29 and hold the upper and lower sections in alinement when the frame is erected. The folded position of the upper member is indicated by dotted lines.

In Figures 6 and 7 the hinged connection between the

uprights

6 and 7 and the cross bar 8 is illustrated in detail. The hinge members 32 are connected on opposite sides at the upper end of upright 7 and are extended to offset the pivot or hinge pin 33 by which the upright is hingedly' connected with cross bar 8 so that this upright can be folded or collapsed against the underside of the cross bar, and the hinge members 84 secured on opposite sides at the upper end of upright 6 have their hinge or pivot pin 35 so located that the upright can be folded or collapsed to the position indicated in the dotted lines in which position it will rest upon the collapsed upright 7. With this construction and mounting, the main supporting frame structure can be readily folded or collapsed, and at the same time this frame structure will fold and set up to make a strong and rigid supporting frame.

While the

slides

13 and 16 can be moved inwardly upon the cross bar 9 when the sup porting frame iscollapsed it is perhaps desirabl e that the spreader members be more compactly folded, and with this in mind I make each of the

spreader members

11, 12, 17 and 18 in two parts and provide a hinge joint at 36 between these parts. This hinge joint is preferably made of the buggy brace type so that the spreader memberswill be secure and rigid when in use.

From the foregoing it will be seen that I that changes and variations can be made without departing from the spirit and scope of my invention.

I claim:
