DETAILED DESCRIPTION OF THE INVENTION
Example I
[0025] According to FIG. 1 to FIG. 6, an integrated folding table
and chairs set comprises a table 1 and two chairs 5 with folding
function.
[0026] The chair 5 comprises the same or symmetrical supporting
legs 6 on both sides, a cushion 7 and a back cushion 8. The
supporting leg 6 comprises mutually crossing front supporting rods
61 and rear supporting rods 62. The front supporting rod 61 extends
upward from the cushion to form a back cushion segment 63. A back
cushion 8 is installed on either back cushion segment 63. The
cushion 7 is fixed to the front supporting rod 61 and rear
supporting rod 62 to form such a structure that the front
supporting rods 61 and rear supporting rods 62 can be folded
together.
[0027] The preferable folding chair structure in this example is as
follows: The cushion 7 is installed on the cushion rod 71. The fore
part of the cushion rod 71 is moveably hinged in the upper end of
the rear supporting rod 62. The rear part of the cushion rod is
moveably hinged in the middle part of the front supporting rod 61.
The mutual crossing of the front supporting rod 61 and rear
supporting rod 62 means that the front supporting rod 61 is hinged
with a sliding sleeve 64. The rear supporting rod 62 runs through
the sliding sleeve 64. A stop block 65 is fixed above the crossing
of the rear supporting rod 62. When the chair is unfolded in place,
the sliding sleeve 64 collides with the stop block 65 forming the
moveable cross structure and stress support. A second cross rod 67
is hinged between two sliding sleeves 64, which can not only
strengthen the transverse stress at the crossing of the front
supporting rod 61 and rear supporting rod 62 and improve the
stability of the chair, but can also ensure smooth folding
operation.
[0028] Furthermore, the cushion rod 71 is composed of two parallel
rods, which are respectively moveably hinged between the upper end
of the rear supporting rod 62 and middle part of the front
supporting rod 61. The cushion rod 71 comprising two parallel rods
can keep the space for the cushion 7 to move downward due to
gravity, so as to avoid the cushion rod to locally support the
user's legs thereunder, which will cause adverse experience. The
front supporting rod 61 on either side is bent by a rod into a
front U-shaped frame. The front cross rod 611 of the front U-shaped
frame is at one end of the backrest segment 63, which can not only
improve the strength of the backrest segment 63, but also provide a
handle for folding operation or carrying. The rear supporting rod
62 is bent by a rod into a rear U-shaped frame. The rear cross rod
621 of the rear U-shaped frame touches the ground, and a first
cross rod 66 is also hinged between the rear supporting rods 62 on
both sides. The first cross rod 66 is arranged at the opening of
the rear U-shaped frame so as to avoid inward contraction of the
rear supporting rods 62 on both sides after the cushion rod 71 is
stressed. The first cross rod 66, the front cross rod 611 and the
rear cross rod 621 of the supporting legs 6 on both sides of the
chair 5 form a rigid link structure to provide a bearing structure.
In addition, the cushion 7 and back cushion 8 are made of not only
the conventional prefabricated sheet material and sponge, but also
of a flexible material, such as Oxford cloth and elastic belt,
preferred in this example. Both sides are respectively fastened on
the cushion rod 71 and the backrest segment 63 of the front
supporting rod 61, so that it is not only portable and foldable,
but also occupies little space, and is especially suitable for
outdoor use.
[0029] Table 1 includes cross hinged table legs 2 on both sides and
a table top 3. The table legs 2 respectively include two cross
hinged U-shaped rods 21. The top cross rod 211 of two U-shaped rods
21 is used to fix and support the table top 3. At least two
U-shaped rods 21 on one side of the table legs have an extension
segment 212 downward from the cross hinge point 22. The extension
segment 212 is respectively hinged in the lower part of the front
supporting rods 61 on the same side of the two chairs 5. The rear
supporting rod 62 on that side of the two chairs 5 extends upward,
is hinged on the other U-shaped rod 21 above the cross hinge point
22, and forms a four-bar linkage support structure with the help of
the local part of two U-shaped rods 21 at the same side, and local
part of the front supporting rods 61 and rear supporting rods 62 of
the chair. Furthermore, the extension segment 212 of the U-shaped
rod 21 comprises a bent cross rod 213. The end part of the bent
cross rod 213 is hinged on the front supporting rods 61 on the
other side of the chair 5. The bent cross rod 213 helps to form a
linkage with the front supporting rods 61 on both sides of the
chair, which not only improves the strength of the lower part of
the bent U-shaped frame of the front supporting rods 61, but also
plays a role in stably supporting the table 1 impending on one
side, and avoids deflection towards the impending side, as shown in
FIG. 2.
[0030] The table top 3 is a rigid folding structure, the middle
part of which is hinged by a hinge structure 31. Both end parts of
the table top 3 are respectively fixed to the top cross rod 211 of
the U-shaped rod 21. When both U-shaped rods 21 are folded, the
table top 3 can be folded along the hinge. More specifically, the
table top 3 is composed of the core board 32 and flexible
waterproof fabric 33, the outside of the core board 32 is wrapped
with the flexible fabric 33, which forms an edge 331 by sewing or
bonding around. There is a gap edge in adjacent part of the two
core boards 32, and the gap edge forms a folding hinge structure
31; the edge 331 at either end of the table top 3 is winded with a
steel sheet 34, and then fixed to the top cross rod 211 of the
U-shaped rod 21, as shown in FIG. 5 and FIG. 6.
[0031] Therefore, it is necessary to design a supporting cross rod
35 under the table top 3, as shown in FIG. 2 and FIG. 3. There is a
bent segment 351 at either end of the supporting cross rod 35, and
the bent segment is bent by a rod into a U-shaped structure. The
end part of the bent segment 351 is respectively hinged above the
cross hinge point 22 of one of the U-shaped rods 21. A supporting
rod 36 is hinged at the extension segment 212 below the cross hinge
point 22 of the other U-shaped rod 21. The other end of the
supporting rod 36 is hinged at the bent segment 351 of the
supporting cross rod 35. The supporting cross rod 35 collides with
the bottom of the hinge joint part of the table top 3 or the bottom
of the table top 3 near the hinge joint part, and plays a role in
supporting the middle part of the folding table top 3. As shown in
FIG. 3, furthermore, a fastening belt 37 is provided at the bottom
of the table top 3, and the fastening belt 37 is sleeved on the
supporting cross rod 35. During folding, the supporting cross rod
35 moves downward, so as to drive the table top 3 to fold
downward.
Example II
[0032] According to FIG. 7, the table top 3 in this example is a
rigid entity, namely a whole sheet material. The bottom at one end
of the table top is moveably sleeved on the top cross rod 211 of a
U-shaped rod 21 through a moveable sleeve 38. An elastic buckle 39
is provided at the bottom of the other end. The table top 3 is
fixed to the top cross rod 211 of the other U-shaped rod with the
aid of the buckle 39. In this structure, there is no need for
additional support. But when the integrated table and chairs are
unfolded or folded, it is necessary to add an operation, as shown
by the dotted line in the figure, that is, only by turning up the
table top 3, can the table top be kept flat for use or folding.
[0033] In conclusion, integrated table and chairs are provided in
the preferred examples. The table top is an impending structure,
which helps to keep the space on one side for users' legs and feet
to get in and out and for activity space, and to get the best
experience. Alternatively, all U-shaped rods 21 on both sides of
the table legs 2 extend downward from the cross hinge point 22,
form extension segments 212, are hinged in the lower part of the
front supporting rod 61 on the same side of the chair 5, and form a
stable four-leg support of the table top 3. This structure also
falls within the teaching of this application. The scheme of an
integrated table 1 and chairs 5 in the present invention is
applicable to forming integrated table and chairs set with linked
unfolding and folding structure on the existing chair with X cross
on any two sides, and is not limited to the chair scheme in this
example.
