[ 57] ABSTRACT A pair of leg frames are pivoted between the ends to present an X formation when open and support a table top. A bench is erected upon each side of the table and includes horizontal tension arms, substantially vertical compression legs and a bench seat. As the horizontal arms are moved from the folded position to the horizontal position, the vertical legs are unfolded and support the bench surface which moves to the horizontal position. The benches are first folded down and then the cross frames are folded together with the table top lying substantially vertically against the folded structure, when the assembly is in the folded or stored position.

1 FOLDABLE TABLE AND BENCH ASSEMBLY BACKGROUND OF THE INVENTION So-called picnic tables usually consist of a table top and a fixed bench, one upon each side thereof. While these are most efficient in use, nevertheless storage and transportation is a problem due to the sheer bulk of these assemblies.

Attempts have been made to provide folding assemblies but these usually require tools and include parts to be dismantled prior to the folding and unfolding action.

SUMMARY OF THE INVENTION The present invention relates to new and useful improvements in table and bench combinations inasmuch as the entire assembly can be folded and unfolded without the use of tools or without connecting or disconnecting any of the parts.

An object of the invention is therefore to provide a picnic table type assembly which can be folded relatively flat for storage and transportation purposes yet which can readily be unfolded for use to provide a stable and firm table and bench assembly.

Another object of the invention is to provide a device of the character herewithin described in which the bench components pass over center when being unfolded so that there is no danger of collapse when in use.

A still further object of the invention is to provide a device of the character herewithin described which is simple in construction, economical in manufacture,

and otherwise well suited to the purpose for which it is designed.

With the considerations and inventive objects herein set forth in view, and such other or further purposes, advantages or novel features as may become apparent from consideration of this disclosure and specification, the present invention consists of the inventive concept which is comprised, embodied, embraced, or included in the method, process, construction, compostion, arrangement or combination of parts, or new use of any of the foregoing, herein exemplified in one or more specific embodiments of such concept.

DESCRIPTION OF THE DRAWINGS FIG. 1 is an end view of the assembly in the erected position but with one bench component partially folded.

FIG. 2 is a section substantially along the line 22 of FIG. 1.

FIG. 3 is a top plan view of the assembly in the erected position with the table top shown in phantom for clarity.

FIG. 4 is an end view of the assembly in the folded position but shown slightly unfolded for clarity.

FIG. 5 is an enlarged fragmentary view showing part of the mounting of the bench to the supporting structure.

FIG. 6 is a fragmentary elevation showing the mounting of the table top to one of the leg assemblies.

In the drawings like characters of reference indicate corresponding parts in the different figures.

DETAILED DESCRIPTION Proceeding therefore to describe the invention in detail, reference should be made to the drawings in which reference characters 10 and 10A illustrate leg frame components. Each of these components includes an upper bar member 11, a lower bar member 12, and a 5 pair of side bar members 13 which extend between the ends of the upper and lower bar members 11 and 12 thus forming a substantially rectangular component. Similar reference characters have been given to the components of the leg frame member 10A except that the letter A" has been added.

The two leg components 10 and 10A are pivotally connected together intermediate the ends of the

side bar members

13 and 13A, by means of a transverse pivot pin 14 and in this connection it will be observed that the leg frame component 10A is slightly narrower than the leg component 10 so that one can fit within the other as clearly shown in FIG. 3. When pivotally connected together, they form a X configuration when viewed in end elevation as clearly shown in FIG. 1 and can be folded upwardly to the closed position shown in FIG. 4 or can be folded downwardly to the extended or erected position shown in FIG. 1. In the latter position, the downward movement of the upper bar members 11 and 11A is restricted by means of flexible linkage 15 extending between the upper bar members intermediate the ends thereof.

A table top 16 consists of a planar panel which rests upon the upper bar members 11 and 11A when in the erected position. The table top is secured to one of the upper bar members 11 by means of brackets 17 extending around the upper bar and member 11 and being secured to the underside of the table top panel 16 by means of screws, rivets or similar fastening means indicated by reference character 18. This enables the table top to pivot on the bar member 11 and to rest on the bar member 11A when in the erected position shown in FIG. 1.

A bench component collectively designated 19 is situated upon the assembly each side of the table top 16 and each component consists of an elongated bench panel 20, substantially vertical leg or compression members 21 and substantially horizontal or tension members 22.

The members 22 are pivotally secured by the inner ends thereof to the transverse pivot 14 and extend outwardly in spaced and parallel relationship two upon each side. Stop means 23 are provided on the outer ends of these members and bearing sleeves 24 engage around these members and can slide inwardly and outwardly therealong, being restricted in the outer move ment by means of these stop means 23.

A cross bar 25 extends between the sleeves 24 and the bench panel is secured to sleeves 24 by means of clamps 26 extending therearound and being secured to the bench panel 20 by means of rivets, bolts or similar fastening means 27.

An elongated sleeve 28 surrounds the lower bar members 12 and 12A and the aforementioned compression legs 21 are secured to these elongated sleeves 28 by means of welding or the like and extend upwardly in spaced and parallel relationship one with the other, it being understood that these are two compression members 21 for each bench assembly 19. Bearing sleeves 29 are provided upon the upper ends of the compression members 21 and these bearing sleeves engage around the aforementioned cross bars 25.

The pivotal action of the compression members 21 and the pivotal action of the tension members 22, in conjunction with the sliding relationship of sleeves 24 upon tension members 22, means that the bench assemblies can be folded inwardly to lie contiguous with the leg frame components 10 and 10A as shown on the left hand side of FIG. 1 or can be folded outwardly to the erected position as shown upon the right hand side of FIG. 1. When moving from the folded to the erected position and vice versa, the compression members 21 pass over the vertical center thus preventing any possibility of the bench assemblies 19 collapsing when in the erected position.

When it is desired to fold the assembly to the closed or stored position, each bench assembly is folded inwardly contiguous with its leg frame component as shown on the left hand side of FIG. I, the table top is raised clear of the upper cross bar 11A whereupon the two leg frame components can be folded upwardly towards one another so that the structure takes the form shown in FIG. 4. Further movement of the leg frame components together, permits the table top panel 16 to lie substantially vertically upon the leg frame component 10 thus making a relatively compact package which is easily stored or transported.

To erect the assembly, the table top is raised thus allowing the leg frame components to be opened to the fullest extent restricted by means of the flexible linkage l whereupon the table top rests upon the other upper bar member 11A. Each bench assembly is then folded outwardly in the direction of arrow 30 to take upon the position shown at the right hand side of FIG. I thus making a stable and firm table and bench assembly.

In FIG. 4, arrow 31 indicates the further closing of the leg frame components and 10A and arrow 32, the downward pivotal movement of the table top panel 16 after the leg frame components have been fully closed one against the other.

Reference should be made to the members 22 upon which the benches slide. In order to provide easy access, the preferred embodiment employs just one of these members situated centrally along the length of the bench and shown in phantom by reference character 22A.

Also in the preferred embodiment, a hinged strap assembly A is used instead of the chains 15. This strap assembly extends between the leg components 10 and 10A and below the pivot pin 14. The extended position of the strap assembly is shown in FIG. ll while FIG. 4 shows the assembly in the folded position.

Various modifications may be constructed or performed within the scope of the inventive concept disclosed. Therefore what has been set forth is intended to illustrate such concept and is not for the purpose of limiting protection to any herein particularly described embodiment thereof.
