Description
Background of the Invention
This invention relates to a collapsible beach chair and more particularly to a collapsible beach chair which when folded up for being carried makes a smaller and more convenient package than heretofore has been possible.
There are a large number and variety of collapsible beach chairs available for use by the public. Unfortunately, even when folded these chairs remain very bulky and difficult to carry or store and often are too heavy to call truly portable. Those chairs which are made less bulky are not comfortable for use or otherwise suffer a variety of drawbacks including buy not limited to lack of leg support.
A number of U.S. Patents are pertinent to but do not teach or suggest the present invention. These are: U.S. Pat. Nos. 3,285,654, 3,475,050, 3,947,903, 4,577,901 and U.S. Pat. No. 4,614,377.
Summary of the Invention
The present invention is for a beach chair capable of being collapsed to a small and compact package which is convenient to assemble and transport.
In a preferred embodiment of this invention, there is provided a beach chair with arm rests, and most importantly is capable of being reduced to a svelte, slim lightweight package which can be conveniently carried as, for example, using a slim zippered bag with a shoulder strap/sling.
It is thus a principal object of this invention to provide a beach chair capable of being collapsed to a convenient package for being carried or transported.
Other objects and advantages of this invention will hereinafter become obvious from the following detailed description of a preferred embodiment of this invention.

Detailed Description of the Preferred Embodiment
Referring to FIGS. 1 and 2, beach chair 10 incorporating the principles of this invention consists of a pivoted back 12, a seat 14, and a pair of arm rest assemblies 16 and 18.
Back 12 is made of a pair of elongated tubular members 22 and 24 spanned by a webbing 26 for supporting the back of the person sitting in chair 10. A removable end member 28 joins the ends of members 22 and 24 to hold the latter apart as shown in the figures when the chair 10 is in use. Member 28 has crimped ends for insertion in the open ends of tubular members 22 and 24 as illustrated.
The bottom ends of tubular members 22 and 24 are pivoted on pins 32 and 34 mounted in brackets 36 and 38 to permit members 22 and 24 to pivot in a manner to be described below.
Seat 14 is made from a pair of parallel tubular elements 42 and 44 spanned by a webbing 46 to support the person sitting in chair 10. The rear ends of elements 42 and 44 support brackets 36 and 38 as illustrated where riveted connections are provided so that brackets 36 and 38 remain integrally attached to elements 42 and 44, respectively.
As seen also in FIG. 2 more clearly, the rear ends of elements 42 and 44 terminate in a pair of transition sections 48 and 52 into which the ends of a removable rear foot support 54 are inserted as illustrated.
The front ends of tubular elements 42 and 44 are curved downwardly into which is inserted the ends of a removable front foot support 56. Removable end member 28 and rear and front foot supports 54 and 56 are identical and therefore interchangeable for ease of removal and replacement when the chair is to be reassembled for use. All of their ends are slightly crimped so as to be easily inserted into the tubular members 22, 24 and 42, 44 in the manner shown.
In order to be able to collapse chair 10 transversely when member 28 and supports 54 and 56 are removed, there is provided, as also seen in FIG. 3, a transverse collapsible assembly 58 consisting of a pair of arms 62 and 64 pivoted on members 42 and 44 with pins 68 and 70 in brackets 42a and 44a respectively, as illustrated and terminating in a U-shaped member 66 on which is mounted a pair of pins 72 and 74 on which the ends of arms 62 and 64 are pivotally joined. To collapse chair 10, members 28, 54, and 56 are removed and member 66 is moved forward as shown by the arrow in FIG. 3 thereby folding arms 62 and 64 flat against each other.
Arm rest assemblies 16 and 18 are identical but mirror images of each other. The following description of arm rest assembly 16 would thus equally apply to arm rest assembly 18.
As also seen in FIGS. 4 and 5, arm rest assembly 16 consists of an arm rest 76 mounted on one side of an angle 78 which may be held in place by screws (not shown) and/or adhesive. The rear end of arm rest 76 is joined in convenient fashion to tubular upright tubular member 22 by a pin 88, to permit pivoting in a manner to be described.
Angle 78 is supported by a strut 92 pivotally attached at its upper end by a pin 94 to angle 78 and through a pin 96 at its lower end to member 42. A pair of stops 102 and 104 limit the travel of strut 92 when it is in the raised position as seen in FIGS. 1 and 2. Arm rest 76 may be made of wood, plastic, or other suitable material.
To collapse chair 10 shown in FIG. 1 in order to transport it conveniently, member 28 and foot supports 54 and 56 are removed, transverse support assembly 58 is folded as seen in FIG. 3 to collapse chair 10 transversely as shown by the arrow in FIG. 3, and back 12 is folded forwardly as shown by arrow B in FIG. 2 causing arm rest assemblies 16 and 18 to pivot forwardly, with the result that chair 10 is collapsed into a compact unit as seen in FIG. 6. The collapsed chair 10 with member 28 and supports 54 and 56 then can be placed into the compact bag 110 shown in FIG. 7 with a zipper 112 and a shoulder strap 114 for convenient carrying of the collapsed and disassembled chair 10, as seen in FIG. 8.
To assemble chair 10, the procedure described above is reversed.
It is thus seen that this invention provides a most unique beach chair which is comfortable when used, convenient when transported, and effortless to disassemble and re-assemble. The construction is likewise inexpensive and, while unadorned, is singularly effective at providing an application clearly capable of wide acceptance.
While only a certain preferred embodiment of this invention has been described it is understood that many variations of this invention are possible without departing from the principles of this invention as defined in the claims which follow.
