Description
This invention relates to the art of portable, foldable tables and chairs, and specifically to a portable table and chair set made of lightweight material and which can be folded and arranged into a compact unit for convenient carrying and storing.
Background of the Invention
The prior art discloses various types of table and chair sets and, individual tables and chairs, which are useful in out door activities such as camping and picnics as well as in conventional use in a home, backyard or patio. All of these articles, however, share a common disadvantage in that they are not conveniently transportable or storable. Typically, prior art tables and chairs are not foldable into a compact configuration and the components of a table and chair set cannot be arranged to be carried or stored as a compact unit.
This invention overcomes these disadvantages and provides tables and chairs which are useful individually or as a set and which can be folded individually into a highly compact configuration and, when used in a set, can be arranged into a compact unit which is easily transportable and storable.
Summary of the Invention
Accordingly, a primary object of the invention is to provide an article for use as a table having support means and twin table top means which are arrangeable into a first, open position wherein they form a continuous table top surface and which are arrangeable into a second, folded position wherein said twin table top means are disposed substantially parallel with respect to the support means and with respect to each other so as to form a compact unit which is easily transportable and storable.
Another important object of the invention is to provide an article for use as a table as indicated above with each of said twin table top means having surface means carried by at least one arm member which is pivotally connected to the support means and the support means having oppositely located pairs of leg members, each pair of which is arrangeable into a first, open position corresponding to the first, open position of the twin table top means and is arrangeable into a second, folded position corresponding to the second, folded position of the twin table top means.
Yet another object of the invention is to provide articles for use as chairs having the same features as the articles enumerated above.
Yet another object of the invention is to provide an article for use as a table which in its folded position is adapted to receive and retain independent articles and thereby can be easily transported and stored.
Another primary object of the invention is to provide a table and chair set wherein the table in its folded position is adapted to receive and retain in a central region thereof a plurality of folded chairs so that the set comprises a compact unit which is easily transportable and storable.
Other objects and advantages will be apparent from the following description of the invention.

Description of the Preferred Embodiment
Referring to FIG. 1, the table of the invention is shown generally at 10 in an open usable position having two pairs of oppositely located leg members 16, 17, 18, 19 which provide support for the table top means. The pairs of leg members 16, 17 and 18, 19 are pivotally connected at substantially their central regions by conventional pivot means 15, 20, respectively. Cross members 23, 24 are fixedly attached to the leg members to provide cross stability across the base of the table when in use in an open position. Additional cross stability is provided by cross member 25 which extends between the internal face regions of leg members 17 and 19 and also provides carrying means for chairs or other independent articles retained by the table when it is in a folded position.
As can be seen in FIG. 5, the table top means is comprised of two half sections, shown generally at 30 and 31, having a plurality of conventional surface planks 12 carried by arm members 26, 27, 28, 29. External arm members 26 and 28 are suitably pivotally connected to external leg members 16 and 18, respectively, to facilitate half section 30 to be swung radially with respect to the axis defined by the respective conventional pivot means 46 and 48. Similarly, internal arm members 27 and 29 are suitably pivotally connected to rod 14 and suitably pivotally connected to internal leg members 17 and 19, respectively, to facilitate half section 31 to be swung radially with respect to the axis defined by the center of rod 14. Conventional pivot means 47 and 49, respectively are provided to accommodate these dual pivotal connections and to permit substantially friction free movement between the internal and external leg members at the pivot point. Referring to FIG. 8, it will be noted that when the table is in an open position, half sections 30 and 31 abut at the center of the table at separation members 34 and form a substantially continuous horizontal table surface. Separation members 34 are carried on the inside edge of the innermost plank 12 and serve to maintain the same separation between the abutting surface planks 12 as between the other abutting surface planks. Stability near the corner regions of the table top is suitably provided in that the three internal surface planks 12 in the respective half sections rest upon the arm members of the other half section when the table is in an open position. The table edges 43, 44 formed by the ends of the exterior surface planks 12 are suitably rounded to minimize the likelihood of injury.
FIG. 2 illustrates a chair, shown generally at 50, which has substantially the same construction as the table described above. Except for size differences, a smaller number of surface planks 52, and the absence of a corresponding separation member 34 and cross member 25, the chair structure identically corresponds to the table structure.
Thus, it will be seen that both the table and the chairs are suitably constructed to be folded into a compact configuration wherein the half sections of the table top means are disposed substantially parallel with respect to each other and with respect to the folded support means as illustrated in FIG. 3. FIG. 9 shows a side view of the table in a folded position. A central opening, generally indicated at 42 in FIG. 4, is provided in the table between the folded half sections and the folded leg members which is adapted to receive and retain by conventional retainment means independent articles of all varieties. In a preferred embodiment, the independent articles received within said opening are the folded chairs of the invention which may be suitably arranged and securely disposed within the opening as shown in FIG. 3. In a preferred embodiment, the base chairs shown generally at A and B in FIG. 7 rest within the opening upon cross member 25. Upper chairs C and D rest upon the respective base chairs. Conventional securement means 72 is provided to secure the unit in a folded position and eliminate the possibility of either half section being swung outwardly open when the independent articles are enclosed within the folded table. The securement means also facilitates the transport and storage of the unit in a horizontal position. The table and corresponding chairs being constructed of a lightweight material, such as wood or a suitable lightweight metal, make the folded unit readily transportable and storable.
It will be appreciated that the folding mechanism of the table and, correspondingly the chairs, is quite simple. Referring to FIGS. 4-6, it can be seen that the table may be opened with a slight upward motion and gentle pushing together of the two half sections as illustrated by the directional force arrows in FIG. 6. The independent leg members in turn pivot about the pivot means and move outwardly in opposite directions. As the leg members continue to swing in opposite directions they draw the table top half sections together and down to abut at separation members 34 and thereby form a substantially continuous horizontal table top. The abutment of the table top half sections correspondingly stops the movement of the leg members and, in effect, locks the table in its open position. To close the unit, a corresponding opposite procedure is used.
It will be noted that although the table and chair set described herein shows a combination of 4-seat capacity table with four chairs, any suitable seat capacity and corresponding number of chairs may be devised.
Although preferred embodiments of the invention have been illustrated and described, it will at once be apparent to those skilled in the art that modifications and betterments of the invention may be made within the spirit and scope of the inventive concept.
It is intended that the scope of the invention be limited not by the scope of the foregoing exemplary description, but, rather by the scope of the hereinafter appended claims when interpreted in light of the pertinent prior art.
Claims
I claim:
