PORTABLE TQILEI R CONVE}1\TIE1}I(},`I 1l Application led February 15, l1927. Serial No. 168,429.

This invention rela-tes to portable strucare pointed so that they may be forced into tures consisting of a vframe and a canvas or the ground. One of these posts which is 55 other fabric cover and the general object identified by the exponent a applied to the of the .invention is to provide a tent-like numeral 10A constitutes theright side door` structure which may constitute a touristl `post for the front of the structure.

Each pair 0f posts is connected by links or Another object is to provide a structure of braces l1 and 12 pivotcd to the correspondthis character rectangular in plan and which ing post at 13, and pivoted to eachother is formed of a collapsible frame which may at their adjacent ends. Preferably one of be`readily folded upto be carried and which these bracing links` as, for instance, the link may as readily be unfolded and set up. l1 is formed with an elongated Groove 13 A further objectI is to provide a collapsiblel whlle the other link is formed witzh an elonframe of this character which will support gated projection or lug 14 adapted to fit in the tent structure so as to provide the roof the groove 13a. A pivot pin 15 in the form of thereof wi-th the proper pitch to permit rain a small bolt passes through the overlapped to run off. ends of the links and through the aperture in A still further object is to provide a structhe recess 13a and in the lug 14 and a coiled ture of this character having corner posts compression spring 16 fits around this bolt,

which may be forced into the ground. bearing at one end againsta stop 17 and at Other objects will appear in the course of the other end bearing against the inner link'.l

This spring, therefore, acts to force the lug My invention is illustrated in the accom- 1.4 into therecess or slot 13* when the two 7o panying drawings wherein zlinks are disposed in alignment with each Fig-ure 1 is a. perspective .view of a portother and thus lock the two links in this able structure constructed in accordance'with alignment. Preferably one of the links, as my invention; the link 11, has a laterally projecting lug Fig. 2 is a fragmentary end elevation of 18 which extends beneath the other link 12 7 the tent supporting structure; so that the links cannotbreak upward.

Fig. 3 is a fragmentary side elevation of From each post and the bracing link 11 3o the Same; which is pivoted thereto,.ex'tend the braces Fig. f1 is a like view to Figure 2 but showformed of the linksl `19 and 20. These linksV ing the structure partially collapsed; are pivoted at their extremities to the post so Fig. 5 is a fragmentary face view lof the and link 11 respectively and pivotally conend of one of the main braces; nected to each other in the same manner Fig. 6 is alike view to Figure 5 but of as are the links 11, that is, the conthe complementary brace; joined ends of the links 19 and 20 are Fig. 7 is a horizontal section through the provided one with a recess and the other 85 conjoined ends of the main braces; with a lug and a spring urges the lug into Fig. 8 is a vertical section through the the recess so as to lock the links in aligned conjoined ends of the main braces. relation. These links are also adapted to Referring to these drawings it will be break downwardly and vwhen they are in seen that the frame consists of four main aligned relation act to support` the main corner posts designated 10. These posts are links 11 or braces against downward thrust. arranged aboutl 3 apart though any other In order to hold the top or roof of the cansuitable dimensions may be used.

Each of the corner posts is providedat its upper and lower ends with outwardly projecting buttons 26 whereby the canvas cover may be attached to the posts .and-

the post 10'sl is not only provided with these buttons 26 but with inwardly projecting buttons 27 at the lower end ot the post and at the middle thereof and an outwardly projecting button 28 at the middle ot the post.

The canvas cover 29 may be formed of separate panels buttoned to the buttons 26 or may be sewed around three sides and at Y the inside to the buttons 27.


the top, so as to provide three walls and a root portion. The front wall 29e ot the canvas. cover is intended to be buttoned at its upper end and free edge to the upper button 26 on the post l()a and is provided with button holes 30 on its tree edge whereby it may either be buttoned to the lower button 26 and the button 28 or buttoned on Thus this door may be opened and closed either from the outside or inside. Preferably one of' the posts is provided with a paper rack or holder 3l.

It will be seen that the structure described may be made of very light material and that when it is folded it will be in compact form for easy transportation and that it may be readily set up at any place desired and that when so set up the corner posts are strongly braced not only to support the weight of the canvas cover but to support the structure as a whole against the action ot wind. I do Vnot wish to be limited to the details of construction and arrangement ot' parts illustra-ted as itis obvious that many changes may be made therein without departing from the spirit of the invention as deiined in the appended claims.
