If the customer desires the table to be of an extended length, the female beam members are pulled apart to expose the interconnecting male beam members and a cover member is disposed over the exposed portion of the male beam members. The table also includes a flange means secured to the beam members for supporting a table top.

8 Claims, 8 Drawing Figures PATENIEDNBV 6 ms l SHEET 1 [IF 2 1 EXTENSIBLE TABLE This invention relates to a table assembly and, more specifically, to one having an extensible frame'whereby the table assembly may be repeatedly manufactured with identical components yet sold in different lengths.

Extendable tables are well known, particularly those of the dining room type which may be extended and a leaf inserted. The instant invention, however, relates to tables having a fixed design which are normally manufactured to a given length. Normally, if it is desired to manufacture a table of a given design in different lengths it is necessary to fabricate components of different sizes to fabricate the table of a selected length which cannot be changed.

Accordingly, it is an object and feature of this invention to provide a table assembly including an extensible frame having at least one female beam member and at least one male beam member, the male beam member being disposed in and extending from a first end of the female beam member with support means disposed between the members for supporting the male beam member centrally within the female beam member for allowing the two beam members to slide relative to one another whereby the table may be repeatetivly manufactured with the same components but sold in different lengths.

In correlation with the foregoing object and feature, it is another object and feature of this invention to provide such a table assembly wherein the support means includes a plurality of pads attached to the female beam member adjacent the first end thereof and a plurality of pads attached to the male beam member adja cent the end thereof disposed within the female beam member.

In correlation with the foregoing objects and features, it is another object and feature of this invention to provide a cover member for disposition over the exposed portion of the male beam member.

In correlation with the foregoing objects and features, it is another object and feature of this invention to provide a pair of spaced plates with notches in opposite extremities thereof associated with eachplurality of pads and with two pads of that pair of the pads disposed with the ends thereof in the notches.

Other objects and attendant advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:

FIG. I is a partially exploded perspective view of a preferred embodiment of the instant invention;

FIG. 2 is a fragmentary cross-sectional view of a female beam member showing one end of the male beam member disposed therein and the cover member disposed about the male beam member;

FIG. 3 is an exploded perspective view of a pad means to be disposed in the distal end of a female beam member;

FIG. 4 is a fragmentary cross-sectional view taken substantially along line 4--4 of FIG. 2 and showing a glass table top;

FIG. 5 is a fragmentary cross-sectional view taken substantially along line 5-5 of FIG. 2 and showing a glass table top;

FIG. 6 is a fragmentary cross-sectional view similar to FIG. 5 but showing an alternative flange means for supporting the glass table top;

FIG. 7 is a fragmentary perspective view of one end of the cover; and

FIG. 8 is an exploded fragmentary perspective view showing alternative pad means associated with the end of the male beam member.

Referring now to the drawings wherein like numerals indicate like or corresponding parts throughout the several views, a table assembly constructed in accordance with the instant invention is generally shown at 10.

The table assembly 10 includes an extensible frame means generally indicated at 12. The frame means 12 includes two parallel and spaced sets of first female beam members 14 and second female beam members 16. The frame means 12 also includes two male beam mebers 18, only one of which is shown. Also included are cross beam members 20 which extend between spaced pairs of the female beam members 14 and 16 respectively. Leg means including the legs 22 extend downwardly from the intersection of the cross beam members 20 and the female beam members 14 and 16 for supporting the table assembly.

Each male beam member 18 has a first end 24 disposed in a female beam member 14. Each male beam member 18 extends outwardly from a first end 26 of a female beam member 14. Each male beam member 18 has a second end (not shown) disposed within and extending from a first end 28 of a second female beam member 16. The ends 26 and 28 of the female beam members 14 and 16 may be moved toward and away from one another as the female beam members 14 and 16 slide over and along the male beam members 18 whereby the distance between the ends 26 and 28 of the female beam members 14 and 16 may be varied as the beam members are slid relative to one another.

The male and female beam members 14, 16 and 18 are four sided or generally rectangular in cross sectional configuration with the male beam members 18 being smaller in exterior cross section than the interior cross section of the female beam members 14 and 16; that is, to the extent that there is a space between the interior of the female beam members 14 and 16 and the exterior of the male beam members 18.

Cover members 30 are included for disposition over the exposed portions of the male beam members 18 between the spaced apart ends 26 and 28 of the female beam members 14 and 16. Each cover member 30 includes spacer means comprising the U-shaped pads 32 at each end thereof for engaging the male beam members 18 to space the covers 30 from the male beam members 18 so that the outer periphery of each cover 30 is contigious with the outer periphery of the adjacent female beam member. Each cover member 30 is generally U-shaped with flanges 34 extending inwardly from the legs thereof for supporting the pads 32.

In a preferred embodiment the outer surfaces of the beam members, legs and covers have a coating of chrome.

The frame means 12 includes support means disposed between the male and female beam members for supporting the male beam members 18 centrally within the female beam members 14 and 16. The support means includes, at the overlapping connection between each male beam member 18 and each female beam member, first pad means generally shown at 36 and second pad means generally shown at 38. The first pad means 36 is attached to one of the female beam members adjacent the first end thereof, such as at first end 26 of female beam 14 as shown in FIGS. 2 and 4. The second pad means 38 is attached to the male beam member 18 adjacent the ends thereof which are disposed within the female beam member. Each pad means 36 and 38 includes a set of four pads with one pad disposed between each side of the male beam member 18 and the adjacent side of the surrounding female beam member. The four pads of each set are divided into two pairs 40 and 42.

There is also included positioning means comprising the plates 44 interconnecting the pads of each set. Each pair of plates 44 are spaced and have notches 46 in opposite extremities thereof, i.e., in the tops and bottoms thereof. The first pair of pads 40 have opposite ends disposed in the notches 46 and the second pair of pads 42 are supported in holes in the sides of the plate. It will be noted that the plates 44 of the first pad means 36 are adjacent the side of the adjacent female beam member, as best illustrated in FIG. 4, but the plates 44 of the second pad means 38 are spaced inwardly from the sides of the adjacent female beam member, as best illustrated in FIG. 5.

There is also included first fastening means comprising the screws 48 interconnecting the adjacent female beam member and the lowermost pad 40 of the first pair to prevent movement of the pad means 36 longitudinally of the associated female beam member.

A second fastening means comprising the welds 50 interconnect the plates 44 of the second pad means 38 and the associated male beam member 18, as best illustrated in FIG. 2.

An alternative embodiment for the second pad means associated with the male beam member 18 is generally shown at 38' in FIG. 8. In FIG. 8 upper and lower pads 40' as well as the side pads 42' are secured to the male beam member 18 by having projections 52 disposed in holes 54. The projections 52 may be press fitted into the holes 54 or the various pads may be adhesively secured to the male beam member 18.

The frame means 12 further includes flange means extending inwardly from the beam members for supporting a table top, such as the sheet of glass 56 shown in FIGS. 4 through 6. In the preferred embodiment as illustrated in FIGS. 4 and 5, the flange means comprises at least one right angle member 58 with one leg thereof secured to a beam member. In an alternative embodiment shown in FIG. 6, the flange means comprises a U- shaped member 60 with the base thereof secured to a beam member.

Although not shown there is included means for preventing relative longitudinal sliding movement between the female beam members 14 and 16 and the male beam members 18. Such may take the form of screws which threadedly interconnect or frictionally interconnect the male beam members 18 and the adjacent female beam members. The purpose of such means is to maintain the table in the selected length.

As will be appreciated from the foregoing description, the table is manufactured and assembled with the pad assemblies 36 and 38 centrally supporting the male beam members 18 within the female beam members 14 and 16. The table may be disposed at its shortest length wherein the ends 26 and 28 of the female beam members abut one another. However, should a table of greater length be desired the opposite ends of the table may be moved apart so as to move the ends 26 and 28 of the female beam members apart to attain the desired table length whereupon an appropriate length of cover 30 may be disposed over the exposed portion of the male beam members. Thereafter a table top of the appropriate dimension, such as the sheet of glass 56, may be disposed on the frame means.

Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
