[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention is used outdoors, for example, in a campground. For example, a table plate is connected to the upper part to form a table, or an erection rod is erected on the upper part, and a barbecue stove etc. The present invention relates to a folding base leg device that is used by mounting the device.

[0002]

[Prior art]

 The Applicant can fold the four support legs to the center and fold them in a bundle (store them in a bundle). When using, for example, the support leg width can be increased or decreased according to the size of the attachment to be placed on top. We have developed a folding stand leg device.

For example, in the folding table leg device disclosed in Japanese Utility Model Publication No. 4-26030, which is proposed by the applicant, four supporting legs standing upright at four positions in front, rear, left and right, and a set of two supporting legs are provided. Connections Composed of four X-shaped support members that pivotally connect the intersections of the connecting rods, and are connected and supported between the front support legs, between the rear support legs, between the right support legs, and between the left support legs. The upper and lower ends of each support leg are provided with immovable fixing members, and a slide body is slidable along the support legs so that they can slide up and down. The parts are pivotally attached to the fixing member, and the left and right lower end parts are pivotally attached to the slide body.

Accordingly, the upper ends of the adjacent connecting support members are pivotally attached to the fixing members at the upper ends of the one support legs, respectively, and the lower ends of the adjacent connecting support members are attached to the slide body of the one support leg. Each part is pivotally attached, and the slide body slides up and down in accordance with the crossing opening of the connecting support member that changes according to the change in the width between the supporting legs.When storing, the crossing angle of each connecting member is reduced. The structure was such that the connecting rails were raised to bring the support legs closer to the center so that they could be bundled together and stored.

[0005]

[Problems to be solved by the device]

 However, the conventional support leg is not configured to be adjustable in length.

Therefore, not only the length of the supporting legs cannot be adjusted, but also if the supporting legs are configured to be bundled and housed as described above, it is not possible to form short supporting legs. Can't be configured with a short leg foldable leg device that can install a barbecue stove.

The reason for this is that in order to erected the support legs in a stable manner, it is necessary for each support leg to have a sufficient standing interval, and therefore the connecting bar of the X-shaped connecting support member has a sufficient length. Is required.

Therefore, in order to bring the support legs which are erected upright with a sufficient space between them, the upper and lower end portions are pivotally attached to the upper and lower sides of the support legs so that they can be bundled and stored in a converged state. The connecting bar of the connecting support member must occur, and a long slide range is required so that the slide body pivotally attached to one end of the connecting bar can slide sufficiently. In other words, the slide body and the fixing member to which the other end of the connecting bar is pivotally attached must be long enough to be separated from each other.

Therefore, in the conventional structure, the length of the supporting leg is naturally restricted, and if the standing interval of the supporting leg is determined, the supporting leg cannot be shortened to a predetermined length or less.

The present invention has found out such a problem in the conventional folding base leg device, and solved the problem by making an improvement, so that it can be configured as a short support leg when used, for example, a table plate. The purpose of the present invention is to realize a folding stand leg device that can be used as a low table if it is provided and can be bundled and stored as usual when storing.

[0011]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

[0012] At least four X's which are pivotally attached to at least four support legs 1, 2, 3, 4 standing upright at four positions in the front, rear, left and right, and an intersection of two pairs of connecting rods 5.5. Connecting support members a, b, c, d, and connecting support members a, b, c, d are arranged between adjacent support legs 1, 2, 3, 4, 2, 4, 1, 4. A fixing member in which one of the upper and lower end portions of both side ends of each of the connection support members a, b, c, d is immovably provided on the support legs 1, 2, 3, 4 to be connected. The other end is pivotally attached to the slide body 7/7/7/7 which is vertically slidably fitted to the supporting legs 1, 2, 3 and 4 which are pivotally attached to and connected to the 6/6/6/6. , The crossing angles of the connecting members a, b, c, d are reduced to raise the connecting bar 5 so that the supporting legs 1, 2, 3 and 4 are brought closer to the central position and can be stored in a bundled state. Configure In the folding pedestal leg device, the support legs 1, 2, 3 and 4 are connected to the fixed pipe 8 and the expansion and contraction pipe 9 so as to be freely adjustable in length, and each of the connection support members a, b, c and d. The upper end of each of the connection support members a, b, c, d is connected to the expansion pipe 9 side through the fixing member 6 or the slide body 7, and the lower end portion of each connection support member a, b, c, d is fixed through the slide body 7 or the fixing member 6. The present invention relates to a folding leg device, which is characterized in that it is connected to the 8 side.

[0013]

[Action]

 For example, the fixed pipe 8 is joined to the lower side and the telescopic pipe 9 is joined to the upper side, and the support legs 1, 2, 3, and 4 are configured to adjust the expansion and contraction, and the telescopic pipe 9 is slid when used to support the support leg 1. , 2, 3 and 4 are shortened to be used as low-height base equipment. For example, if a table plate 10 is attached to the upper portions of the support legs 1, 2, 3, 4 it can be used as a low table.

Of course, it is also possible to design the stretchable pipe 9 so that it can be pulled up to increase its overall length for use.

When the apparatus is bundled and stored in a bundled state when not in use, the telescopic pipe 9 is pulled up to make the entire length longer, and the sliding range of the slide body 7 or the slide body 7 and the fixing member 6 are sufficient. Try to get away.

In this state, when the supporting legs 1, 2, 3, 4 are moved toward the center, the connecting bar 5 of each X-shaped connecting support member a, b, c, d rises and each supporting leg. The legs 1, 2, 3 and 4 are centrally bundled and stored.

That is, even if the supporting legs that cannot be expanded and contracted are simply set to be short, the supporting legs that have a standing space that cannot be focused in the center can be stored in a bundle, or can be stored in the center but can be stored in a sufficient standing space for each supporting leg. Even a short support leg that cannot be opened can be moved from a long state to a short state, and when used, it can have a sufficient standing interval while using a short support leg.
