FOLDABLE TABLE WITH HINGED TOP Filed Feb. 13, 1956 2 Sheets-Sheet 2 Fia.

f INVENTOR. FRANK Wesaecuea,

BY v 2 Arm/war nite This invention relates to an improvement in collapsible tables and particularly to tables that may be collapsed for convenient storage or, when collapsed may serve as an ornamental screen for a fireplace.

The invention contemplates a. preferably square table top and a group of supporting leg devices and with certain of the legs being relatively fixed while other of the legs are swingable toward the fixed legs to lie closely adjacent thereto and with the table top being hingedly connected in a manner whereby it is shiftable forwardly and downwardly to lie closely adjacent the collapsed legs and in a substantially perpendicular position with a lower corner having resting engagement upon the floor as an aid in maintaining the device in an upstanding position either for storage against a wall or when serving as a fireplace screen panel.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being bad to the accompanying drawings wherein has been illustrated a preferred embodiment of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

In the drawings:

Figure l is a top plan view of a table constructed in accordance with the invention, with the table top being broken away to illustrate the supporting leg structure in elevation,

Figure 2 is a perspective view of the device and with the table top being shown in dotted lines,

Figure 3 is a front elevation of the table in the fully collapsed position and ath the table top being shown in the screen forming position,

Figure 4 is a vertical section taken substantially on line 44 of Figure 2,

Figure 5 is a view similar to Figure 4 but with the parts in the fully collapsed position, and

Figure 6 is a horizontal section taken on line 6-6 of Figure 4.

Referring specifically to the drawings, the numeral 5 designates a supporting structure as a whole and whereby to support a table top 6. The structure 5 constitutes a pedestal that has central underlying relation to the top 6. The support 5 includes a pair of spaced apart and vertically arranged

tubular legs

7 and 8. The

legs

7 and 8 include a horizontal base extension 9 and horizontal and parallel upper extensions lb. The terminal ends of the base extensions 9 are downwardly bent and are provided with cushion pads 11. As clearly shown, the extensions 9 and 10 of the

legs

7 and 8 extend in diametrically opposite directions whereby the upper extensions 10 underlie and support the table top 6. The

legs

7 and 8 are relatively fixed with respect to each other by

brackets

12 and 13. The

brackets

12 and 13 constitute bearings for

leg sections

14 and 15. The leg section 14 is bent to provide a horizontal base extension 16 while the leg section 15 is bent to provide a horizontal base section 17. The

sections

16 and 17 lie in the same plane as the extensions 9 States Patent 0 ICC and their terminal ends are likewise provided with cushioned pads 18. The

leg sections

14 and 15 are perpendicular and parallel and also parallel with respect to the

legs

7 and 8. The leg section 14 adjacent its upper end is ofiset at 19 and with the offset terminating in a horizontal upper extension 20 that is disposed in the same plane as the extensions 10 and likewise serves to underlie and support the table top 6. The leg section 15 is provided with an upper horizontal extension 21 forming an underlying support for the table top 6 and the terminal end of the extension 21 is upturned at 22 to have snapping engagement within a preferably metallic socket 23 fixed within a recess 24 of the underside of the table top.

The brackets 12, as clearly shownin Figure 6 are formed in pairs and clamp upon the opposite sides of the

leg members

7 and 8 through the medium of bolts 25, thus establishing lower bearings for the

leg sections

14 and 15 while at the same time rigidly binding upon the

leg members

7 and 8 to support them in relatively fixed relation to each other. The upper clamps 13 likewise have clamping engagement with respect to the legs 7 and S and simultaneously serve as a clamping means for a fixed hinge plate 26, that is clamped against the side of the

legs

7 and 8 whereby the hinge plate is rigidly supported against movement with respect to the

legs

7 and 8. Plate 26 at its upper end is provided with a hinge joint 27 for hinged connection with a hinge plate 28. The hinge plate 28 is also provided with an upper hinge joint 29 that is hingedly connected to an elongated hinge plate 30 that is fixedly connected to the underside of the table top 6 through the medium of screws 31 or like fastening devices. The offset 19 provides adequate clearance for the swinging movement of the leg 14 to and from a collapsed position with respect to the

hinge elements

27, 28 and 3%). It is contemplated that the

legs

14 and 15 be rotatably supported within the

bearing brackets

12 and 13 to be shiftable in a horizontal plane in the direction of the arrows in Figure l to and from a collapsed position with respect to the relatively

fixed legs

7 and 8. Suitable stop means, not shown may be employed to limit the swinging movement of the upper extension 20 of the leg 14 to thus dispose the extension 20 in a position atright angles to the upper extensions 10 when the table is in the fully extended position. While the

legs

14 and 15 have been shown in spaced apart relation, it will be apparent that they may be closely arranged and with the

bracekts

12 and 13 preventing outward movement with respect to each other. While the leg devices have been shown and described as tubular, it will also be apparent that they may be of solid cylindrical steel construction.

In the use of the device, with the table in the fully ex tended position as illustrated, in Figures 1, 2 and 4, when it is desired to collapse the device for storage or other purposes, the operator first shifts the leg 14 and its upper horizontal extension 20 in the direction of the arrow in Figure 1, to a position where its pad 18 has abutting engagement with an adjacent pad 11 carried by one horizontal extension 9. In this position, the table top may be shifted downwardly upon the hinge joint 29, permitting the disengagement of the upturned end 22 from the socket 23, at which time the leg 15 is shifted in the direction of the arrow to lie closely adjacent the leg structure '7 and its horizontal extension 9. In the fully collapsed position the several legs are now in closely adjacent positions with respect to each other, shown more clearly in Figure 5. At this time, table top 6 is continued in the forward and downward movement upon the hinge joint 27 to a point where a corner of the table has resting engagement upon the floor A. Thus, the table top functions as an additional supporting means whereby the entire mechanism is supported in an upright position against tilting. The plate 28 is so dimensioned as to position the table top in its col- Patented May- 7, 1957 lapsed position sufiiciently far enough in advance of the collapsed legs as to provide this additional bracing against tilting. When the table is to be extended, the table top is shifted upwardly. upon its hinge plates to a position closely approximating a horizontal'position, at'which time the leg is rotated to swing its upper extension 21 in an arc to cause. the upturned end 22 to engage within the socket 23, in which position the extension 21 is at a right angle to the extensions 10. With the end ZZ engaged within its socket 23, the table top has assumed a horizontal position and, at this time the leg 14 is rotated causing its horizontal extension to move to a right angle position with respect to the extensions 19. The table is thus rigidly supported in its horizontal position by the oppositely extending and substantially equidistantly spaced

extensions

10, 20 and 21.

It will be apparent from the foregoing that a very novel collapsible table structure has been presented. The

legs

14 and 15 and their upper and

lower extensions

16, 17 and 20 and 21 arequickly and easily shiftable to permit the table top to be swung forwardly and downwardly to assume a perpendicular position and to have resting engagement with respect to the floor. No separate fastening devices are necessary to maintain the legs in their relative positions, since the extensions 10, 20and 21, will have a normal frictional contact with the undersurface of the table top 6. The novel form of hinge construction. presents a very desirable mounting for the table top with.

respect to the leg structures and the leg 14 at its offset 19 permits the use of such a hinge construction. The device readily lends itself to various forms of tables, such as card tables, kitchen tables or other utility tables, is relatively cheap to manufacture, is easily assembled or disassembled for shipping purposes and greatly facilitates the use of a table structure where storage capacity is at a mini-' mum and, when in the collapsed position permits the device to be placed closely adjacent a wall area or in front of a fireplace as an ornamental screen.

It is to be understood, that while a preferred form of the device has been illustrated and described, mechanical changes are contemplated as readily fallv within the spirit of the invention as shall be determined by the scope of the subjoined claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
