This invention relates to a portable sun shelter and more particularly to one comprising connected frame members and a canopy which may be used on lawns or beaches.

It is the general object of this invention to provide a light compact sun shelter that is easy to erect and which is stable and secure in use.

A more specific object of the invention resides in the provision of a collapsible frame structure having relatively few separate parts.

A further and specific object of this invention is to provide a generally rectangular framework having pivotally interconnected side frames adapted to pivot in a common plane into a compact bundle and articulated members that are interengageable with the side frames to produce a rigid rectangular structure.

In its more specific aspect, this invention includes a shelter frame structure having novel interlocked joints with associated latching means for maintaining the joints in locked condition.

These and other features contributing to ease of assembly, stability in use and economy of manufacture will be more fully understood from the following detailed description of a preferred embodiment taken in connection with the accompanying drawings in which:

In general, the sun shelter of this invention comprises a pair of side frame assemblies having front and back frame members of rod-like formation adapted to form a generally rectangular framework, the top of which inclines rearwardly, and a canopy connected b detachable fastening means to the framework thus provided in order to cover the top and a lateral side.

Referring to Figs. 1, 2, 3 and 4, the reference numeral designates the complete sun shelter, the principal Components of which are opposite side frame assemblies 22 and 2- a front frame member 26 connecting the upper ends of the side assemblies, and a back frame member it connecting the rearward ends thereof. In the preferred embodiment, these assemblies and members are made of lightweight, tubular metal, although it will be understood that wood strips either square or round may be used. A canopy 3%, preferably of awning material, extends over the frame members 26 and 28 and the upper ends of the frame assemblies 22 and 24 to provide a roof covering with downwardly hanging marginal portions. The canopy 39 can also be extended to close the rear side of the shelter as may be necessary when the sun is low or protection against the Wind is desirable.

A pair of auxiliary cross members 32 and 34 may be connected to the upper portions of the side frame assemblies 22 and 24 in a parallel spaced relation so as to provide an article support, e. g., a baby hammock, an odds and ends trough, or the like.

As the side frame assemblies are identical, only assembly 22 will be described in detail. Fig. 4 shows the manner in which the side frame assemblies are fabricated with a continuous diagonal support member 36 having a pivot pin connection 3'! with a pair of elongated S-shaped brackets 38, riveted, welded or otherwise secured to opposite sides of parallel and oifset upper and lower diagonal support members 40- and 42 respectively, with the member extending between the braokets. At the upper end of the support member Ml, a pair of generally triangular bracket plates id and 35 are secured in outwardly extended relation by means of rivets or the like. A topside frame member Ali-extending 3 in acute angle relation to diagonal member is also secured between the bracket or plates 44 and 45 by means of a pivot pin 48.

Another pivot pin secures the rear end portion of the side member 46 in between an opposed pair of triangular brackets 52 spanning an obtuse angle intersection of the end assembly and having extended corner portions between which are fixedly secured the upper end of a back supporting member 56. The member 56 is vertical and has an inclined upper end complementally engaging the projecting portion of the side member 46, as shown in Fig. 9.

It should also be noted at this point that the continuous diagonal supporting member. 36 has its upper end complementally inclined for engagement with the underside of the member 46, and that it also abuts the vertical supporting member 56 within a pocket 58 formed by brackets 52. The hinge connection of top frame member 45 to vertical supporting member 56 afforded by bracket plates 52, 52 and pivot pin 50 inwardly of said member prevents outward movement of member 56 beyond the vertical position shown.

Referring again to Fig. l, the vertical supporting member 56 has an opposed pair of right angled brackets in the form of plates 69 secured to the opposite sides of its end portion in order to define with the supporting surface a pocket'receiving the lower and correspondingly inclined end of the diagonal supporting member 42 to anchor the same.

In order to afford additional stability when strong winds are present, each of the side frame assemblies 22 and 24 may be provided with a lateral brace member 64 connected by a hinge 66 to the pivot pin 3'! joining the diagonal member 36 to the brackets 3! as shown in Fig. 12. This mounting permits the brace 6-4 to be adjusted for engagement with rolling ground and to be swung upwardly and pivoted for face-toface engagement with the rest of the respective side frame assembly.

A rear brace member 68, best illustrated in Figs. 1 and i, is likewise connected to the lower end portion of each back supporting member 56 by means of a pair of opposed V-shaped brackets 10, riveted or otherwise fixedly secured to the inner and outer sides of member 56, and carrying a pivot pin connection 12 for the upper end of l the rear brace 58. The connection of the rear brace 68 is such that it may be swung upwardly into engagement with the supporting member 56 when the framework is to be collapsed for ready carrying.

One of the particular features of this invention is the construction of the separable rigid joint between the side frame diagonal member 49, the top sideframe member 46 and the front frame member 25, which joint is best shown in Figs. 6, '7 and 8. Near the outer end of its uppermost edge as seen in Fig. '7, the inner bracket 45 is formed with a square notch IA-corresponding to the external diameter of the tubular frame member 26. In assembled relation, the tubular member 26 lies within the notch '14 and has a squared end abutting the inside of the outer bracket 44 as shown in Fig. 8; A metal clip 16 is secured by riveting or welding to the upper side of the member 25 and has a downturned end 1'! which extends in spaced parallel relation to the end of member 26 so as snugly to receive the thickness of the outer bracket 44. The rigid joint thus; formed is maintained against accidental separation by means'of a catch or latch l8 pivotally connected by a pin to the upper surface of the top side frame member 46 for swinging into position such that its outer end portion engages and clamps the extended part of the clip 16. While the latch 78 may be readily moved to an unlatched position, the friction of its connection will ordinarily be sufficient to prevent unassisted movement.

A generally similar but somewhat different locked joint is formedbetween the overhanging rear end portions of the top side frame member 46 and the corresponding end of the back frame member 28, the details of this latter connection being shown best in Figs. 9, 10 and 11. A clip 82 is riveted, welded or otherwise fixedly secured to the inner side face of the frame member 48 and is formed with a right angle end 84 extending in spaced parallel relation to the end of the member 46, the space corresponding to the diameter of the back frame member 28 which has its end positioned therein. The back frame member 28 in turn has a similar clip 86. riveted, welded or otherwise fixedly secured to its top surface and formed with a right angle end 88. spaced a distance from the squared end of the member 28 sufficient to provide a slot space which snugly receives the thickness of the clip 82 when the joint is interlocked in the manner shown in Fig. 10. By means of a catch or latch 99 connected to the upper side of the side frame member 46 by a pivot pin 92, this interlocked joint may be held against separation by pivoting of the latch into the appropriate overlapping relation shown in full lines in Fig. 10 and previously describedfor latch 78.

The means for mounting the auxiliary and op-- tional cross members 32 and 34 between the side frames 22 and 24 is illustrated in Fig. 13. This figure shows only the mounting of the cross member' 32 on the diagonal support 35; but it will be understood that the spaced mounting of the cross member 34 on the upper part of back support 55 is identical in every respect and need not be described. A right angle strip 94 is fixedly secured as by rivets to one side of an end'portion of cross member 32 so as to provide a continuation of the end surface of said member and rest against the adjacent surface of the diagonal member 38. This continuation part of the angle strip 94 is formed with an opening 96 for receiving a locking pin 98 which also passes through aligned openings 99 in the diagonal member 36. Preferably. a chain connection Hi0 will be provided. between the cross member 32 and the lockin and supporting pin 98 so that the latter will not become lost.

Fig. 14 shows an anchoring stake illl in the form of a heavy, U-shaped wire having its ends pointed. One of these anchoring stakes 50. can be used to anchor the lower ends of the diagonal supporting members 36 and the ground engaging ends of the side and back braces 64 and S3 to the ground, one leg of the pin passing through a suitable opening provided in the respective members and braces. The stabilizing advantages of this additional anchoring will be apparent from a consideration, of Figs. 1, 2 and 4. It'has been found that the sun shelter 2!! as thus assembled and anchored can withstand winds of considerable velocity without being upset or moved.

The upper surfaces of the frame members 23. 28 and 46 are provided with spaced snap fasteners I02, the complemental parts of which are secured in appropriate spaced relation to the canopy 30 so that the latter may be readily and securely fastened to the framework in the manner shown. If'desired, aback drop piece I04 of the canopy may be detachably secured to the upper portion by a plurality of spaced snap fasteners I06 of conventional construction as indicated in Fig. 4. The rearwardly inclined roof structure of the canopy 3e and the relatively low height thereof provides a very convenient and conspicuous locatiton for a panel A which may be marked with decorative, identifying or advertising material.

While it is believed that the operations necessary to the assembly, disassembly and use of the portable sun shelter of this invention will be largely obvious from the preceding detailed description, a short summary will be given. The auxiliary cross members 32 and 34 which strengthen the framework and provide support for an article container may be first separated by removal of the locking pins 98 which remain connected tothe respective cross members. As previously pointed out, the shelter 2!] can be used without these auxiliary cross members. After the canopy so has been detached from the top side frame members 46 and the front frame member 26, the latter will be unlatched and separated from the two side frame assemblies 22 and 24. The canopy 3D will be left connected to the back frame member 28 which will then be unlatched and removed. Upon unanchoring of the lateral and rear braces 64 and 68, if stakes llll have been used, each of the side frame assemblies 22 and 24 may be laid down and collapsed or folded together in a substantially common plane. To do this, the sub-assembly comprising top frame member 46 and the vertical back support 56 will be swung upwardly as a unit about the pivot pin 48 as will be understood from a consideration of Fig. 4. This upward swinging movement will free the upper end of the continuous diagonal support 36 from the pocket 58 betwen the spaced brackets 52, and the lower end of the diagonal support 42 from its secured position between the opposed bracket plates Ell. Either before or after doing this, the back brace 68 will have to be turned around the pivot pin 12 until it lies in approximately parallel engagement with the back support 56 with its free end adjacent the hinge connection at pivot pin 50. The continuous diagonal supporting member 36 may now be rotated counterclockwise until it lies parallel to the diagonal supporting member Alb-42. frame member l6 and the back support 56 have been swung together by relative movement with respect to the pivot pin 5t, these members and the diagonal supporting members 36 and 40- 12 may be moved together into a compact bundle which will be completed when the lateral brace 64, which is hinged for movement in a plane perpendicular to that of the other end frame members, has been collapsed into engagement and alignment with the remainder of the bundle.

Recollecting that the canopy 3!! has been left connected with the back frame member 28, it will now be necessary only to place the two completely folded and collapsed side frame assemblies 22 and 2 3 on the canopy adjacent the back frame member and to add the front frame member 26 and the auxiliary cross members 32 and 34 to the bundle. The canopy $9 and the shelter frame members may finally be rolled into a neat compact package within the canopy 30 as illustrated in Fig. 15. The bundle may be tied by cords as indicated and the back frame member 28 gripped with the awning material of the canopy as a handle.

For a beach shelter of ordinary size, the bundle After the top thus formed will weigh approximately 15 pounds and may be carried or stored very easily.

There has thus been provided a portable sun shelter having a fully braced framework of four basic components which may be collapsed into a very compact bundle. This has been accomplished without objectionable increase in weight or cost of manufacture.

While a preferred embodiment of the invention has been described in detail, such embodiment is merely for the purpose of illustration as it will be understood by those skilled in this art that various changes can be made in the details of construction and the arrangement of parts without departing from the spirit of the invention and the scope of the appended claims.
