Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an improvement of a portable folding table used outdoors, at home, on the roof of a building, etc.

[Conventional technology and its problems]

In the past, portable folding tables and folding chairs have been devised and commercially available for use outdoors, but they are either independent or require the table and chair to be assembled and connected at the installation location. It is something that cannot happen. For this reason,
Each requires a support leg, which increases the overall weight, and it is difficult to quickly assemble at the installation location, and since each needs to be carried separately, it is disorganized and one may be forgotten. There are drawbacks.

[Means to solve problems]

Focusing on this point, the present invention is a portable case that serves as a table and a folding chair that are folded together to form an integral unit, and the table is also supported by the chair legs of the folding chair. This is a portable case in which two symmetrical half-cases, each of which has a chair storage space inside, are joined together at one edge so that they can be opened and closed so that when both are opened, the wide surface of the half-cases forms a table surface. A folding chair is folded and stored in each chair storage chamber, and a folding chair is interposed between the folding chair and a half case so that when the case is closed, the folding chair is stored in the chair storage chamber in a folded state and the case is opened. A parallel link mechanism that supports the half case on the chair seat frame in a sometimes straight state, and this parallel link mechanism is connected to a pair of first links whose ends are directly connected and pivoted to the chair frame and the bottom corner of the half case, respectively. a cross link consisting of a member and a second link member disposed between the link members; and a cross link having one end pivotally connected to the chair frame and the other end pivotally connected to one end of the second link member. 3 link members and a pair of fourth link members, one end of which is pivotally connected to the other end of the second link member, and the other end of which is pivotally connected to the half case, and the chair legs are A table with a portable chair that also serves as table legs is provided with the following straightness restraining means for the parallel link mechanism.

That is, one end is pivotally supported at the center of one side of the chair frame so as to be located between the pivot joints of the pair of first link members to the chair frame, and the other free end is connected to the chair frame when the case is opened. A lock rod contacts the middle position of the second link member, and the free end of the lock rod is biased in the contact direction so that the second link member is received in the chair frame via the lock rod when the case is opened. The gist is that it is equipped with a spring that

〔Example〕

What is shown in the figure is a table with a portable chair in which semicircular grooves 7, 7' for supporting parasol supports are formed in the overlapping side walls of the half case 2 when it is opened. This table has a parallel linkage 5 interposed between a folding chair 3 and a half-case 2. This parallel link mechanism 5 is stored in the chair storage chamber 1 in a folded state when the portable case 4 is closed (as shown in FIG. 1), but when the case 4 is opened (as shown in FIGS. 2 to 4). (shown) is configured so that the half case 2 is supported by the chair frame 10 in a straight state. Specifically, the parallel link mechanism 5 includes a pair of first link members 8, 8 whose both ends are directly pivotally connected to the chair frame 10 and the bottom corner of the half case, respectively, and one link member disposed between the link members. a cross link consisting of a second link member 8', and a third link member 9 whose one end is pivotally connected to the chair frame 10' and the other end is pivotally connected to one end of the second link member 8'. a bending link consisting of a pair of fourth link members 9', 9', one end of which is pivotally connected to the other end of the second link member 8', and the other end of which is pivotally connected to the bottom corner of the half case 2; It consists of

Further, the straightness restraining means of the parallel movement link mechanism 5 is pivotally supported by the chair frame 10, and its free end is brought into contact with the intermediate position of the other one of the cross links 8, 8', and is supported by a spring 11. An example is shown in which a locking rod 12 is used in which force is applied in the direction of enlarging the cross narrow angle, and this parallel movement linkage mechanism 5 is
A case is shown in which the folding chair 3 is pivotally connected at an intermediate position in the longitudinal direction.

That is, in this table with a portable chair, the chair frame 1 of the pair of first link members 8, 8 is
One end is pivoted to the center of the chair frame 10 so as to be located between the pivot points to the second link member 8', and the other free end comes into contact with the intermediate position of the second link member 8' when the case 4 is opened. A spring 11 urges the free end of the lock rod 10 in the abutting direction so that the second link member 8' is received in the chair frame 10 via the lock rod 12 when the case is opened. When the case 4 is opened, the parallel link mechanism 5 is restrained in a straight state by the lock rod 10 with the spring 11 as shown in FIGS. be.

In the figure, reference numeral 13 indicates an engaging element provided at the opening edge of the half case 2, reference numeral 14 indicates a handle, reference numeral 15 indicates a hinge, and reference numeral 16 indicates an auxiliary support shaft for opening and closing. 17 is the chair leg 6 of the folding chair 3.
It is a bending link for folding the chair legs 6, and the left and right chair legs 6 are long enough to form a V-shape when they are straight. The free end portion and the center portion of the folding chair are connected and pivotally attached.

The portable chair-equipped table configured above is
This is the appearance of the carrying case as shown in the figure, and when in use, after releasing the engagement of the engager 14 and opening the left and right half cases 2, the folding chair stored in the chair storage chamber 1 is opened. 3, each chair leg 6 is erected.
At this time, the chair leg 6 comes to raise up the bending link 17 pivotally attached to the free end thereof using the pivot of the bending part as a support axis. After the bending links 17 are straightened and each chair leg 6 is erected in a safe state, the chair frames 10 and 10' stored in the chair storage chamber 1 are pulled out by holding the bending links 17. ,
The chair frame part rotates while being restrained by the first link members 8, 8, which are directly connected among the cross links of the parallel movement link mechanism 5, and the bending links 9, 9' and the second link member 8' of the cross link. It is assembled by making it straight. At this time, the locking rod 12, which is pivotally supported on the chair frame 10, is automatically brought into contact with the other link so as to prevent the intersecting link from moving relative to each other. Therefore, in this abutting state, the connecting body consisting of the second link member 8' and the bending links 9, 9, 9' is attached to the chair frame 10 via the locking member 12 at the abutting portion. While being supported, it will be in a straight state and will be securely fixed.

On the other hand, when storing by folding, the assembly procedure described above may be performed in reverse. First, the chair legs 6 are folded, and then the locking rod 12 is swung against the spring biasing force to make contact with the link. After that, the parallel movement link mechanism 5
The bending links 9, 9' are bent and housed.

[Action and effect]

As described above, when storing a folding chair in two half-cases, the present invention has a structure in which the half-cases and the folding chair are connected and pivoted to each other by a parallel movement link mechanism that is bent and stored into the half-cases. Therefore, the table formed by the unfolding of the half-case is safely supported on the folding chair by the links that make up the translation link, and the folding chair is supported by the chair legs, so that the table The space underneath is large, and since there are no legs for the table, the table as a whole is light and extremely easy to carry and use. In particular, the folding chair and the half-case that houses it are pivotally connected and can be folded together, eliminating the need for forgetting to carry one of the chairs and the need for assembly at the installation site, which would otherwise occur in the case of separate configurations. This has the effect of providing a safe portable table with chairs that can be assembled and folded extremely easily and in a short time, and has excellent assembly strength due to the function of preventing bending of the links by the spring-biased locking rod.
