DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used outdoors, for example, in a campsite, in which an erection rod is erected on the upper portion, and a table plate is connected to the upper portion via the erection rod. The present invention relates to a folding stand leg device which is used by forming a table or placing a placing object such as a barbecue stove on the erection bar.

[0002]

2. Description of the Related Art The applicant can fold (store in a bundle) a bundle of four support legs centered on each other. When using, the support leg width can be increased according to the size of the object to be placed on the upper part, for example. We have developed a folding stand leg device that can be made or reduced.

For example, an actual fair 4-2 proposed by the applicant.
In the folding base leg device shown in Japanese Patent No. 6030, four X-shapes are pivotally attached to four support legs standing at four positions in front, back, left and right, and an intersection of two pairs of connecting rods. The connection support members are arranged between the front support legs, between the rear support legs, between the right support legs, and between the left support legs. For example, at the upper end of each support leg. Each of them is provided with a fixing member which is immovable, and a slide body is slidably fitted along the support legs, and the left and right upper end portions of each of the connection supporting members are pivotally attached to the fixing member, and the left and right lower end portions are Each of them is pivotally attached to the slide body, and U-shaped connecting members are provided on the upper ends of the four support legs.

Therefore, the upper ends of the adjacent connecting support members are pivotally attached to the fixing members at the upper ends of the one supporting legs, respectively, and the lower end parts of the adjacent connecting support members are attached to the slide body of the one supporting leg. And the slide body slides up and down in accordance with the cross-opening degree of the connecting support member that changes in accordance with the change in the width between the supporting legs, and the crossing angle of each connecting member is reduced during storage. The structure was such that the connecting bar was raised to bring the support legs closer to the center so that they could be stored in a bundled state.

Further, two erection rods are press-fitted into the U-shaped connecting members provided on the upper end portions of the four support legs from above to erect the erection rods between the support legs, and a table board or barbecue stove is installed. Was configured so that it could be placed on two erection rods.

Operation: The mounting portion 6 of the support leg 1 of the stand leg device a in the opened state
At least two erection rods 5 are installed between the supporting legs 1 in a state of facing each other between the supporting legs 1, and a predetermined number of horizontal rods 8 are provided between the two erection rods 5 at both ends of the horizontal rods 8. The inverted U-shaped connecting members 7 are press-fitted onto the erection rods 5 from above and erected at predetermined positions.

[0013]

[Embodiment] In this embodiment, at least four X-shaped connections are formed by pivoting the intersections of four support legs 1 standing at the front, rear, left and right, and four pairs of connecting rods 2A. The support member 2 is provided, and the connection support members 2 are arranged between the adjacent support legs 1, and the lower end portions of both side ends of the connection support member 2 are fixed to the support legs 1 to be connected so as not to move. The upper end portion is pivotally attached to a slide body 4 which is pivotally attached to the member 3 and which is vertically slidably fitted to the support leg 1 to be connected, and the crossing angle of each connection support member 2 is reduced to raise the connection bar 2A. To form a base leg device a capable of accommodating and accommodating the respective support legs 1 toward the center position and bundling them in a bundled state.

A U-shaped connecting member 6 is provided as a mounting portion 6 for mounting the erection rod 5 on the upper end portion of the support leg 1 of the base leg device a.
A is provided, and both ends of two pipe-shaped erection rods 5 are press-fitted into the U-shaped connecting member 6A to detachably erected between the support legs 1. A horizontal rod 8 that employs two rectangular pipes 7 provided with opposite U-shaped connecting members 7 at both ends is inserted into the erection rod 5 from above with the inverted U-shaped connecting members 7 interposed therebetween. It is fitted and installed detachably.

Inverse U provided at both ends of the horizontal rod 8 of the rectangular pipe
The V-shaped connecting member 7 has an inverted U-shaped fitting surface 9 having the same diameter as or slightly smaller than the outer diameter of the fitting rod 5 to be fitted, and the fitting rod 5 can be fitted into this fitting surface 9. Is a plastic member provided with a press-fitting inlet 10 narrower than the diameter of, and the press-fitting inlet 10 of the inverted U-shaped connecting member 7 is applied to the erection rod 5.
By pressing, the press-fitting inlet 10 can be opened to be fitted into the fitting surface 9, and thereafter the inverted U-shaped connecting member 7 is fitted to the holding rod body 5 in the embracing state by the elasticity of plastic. , Can be connected.

The U-shaped connecting member 6A, which is the mounting portion 6 provided at the upper end of the support leg 1, has a structure in which the press-fitting inlet 10 of the inverted U-shaped connecting member 7 is opened upward. By applying the erection rod 5 to the press-fitting inlet 11 of the U-shaped connecting member 6A and pressing the erection rod 5, the erection rod 5 is press-fitted into the U-shaped connecting member 6A. It can be fitted and connected.

The press-fitting degree of fitting between the erection rod 5 and the U-shaped connecting member 6A and between the erection rod 5 and the inverted U-shaped connecting member 7 is removed when the erection rod 5 or the horizontal rod 8 is lifted. Support leg 1 with lower connecting support member 2
It can be detached so that the (base leg device a) is lifted up and the support leg 1 is manually pressed to pull up the erection rod 5 or the erection rod 5 is manually pressed to pull up the horizontal rod 8. The press-fitting degree is set.

Since this embodiment has the above-mentioned configuration,
The erection rod 5 and the horizontal rod 8 can be attached to the support leg 1 of the platform device a with one touch, and the erection of the erection rod 5 and the horizontal rod 8 can open and close the support leg 1 in the erection direction of the horizontal rod 8. The base leg device a is fixed and can be stably erected, and even if the base leg device a is narrower than the interval between the support legs 1, it can be mounted with good stability.

Further, a placing object 12 such as a barbecue stove may be placed on the horizontal rod 1 so as to be stably supported, or the placing object 12 is supported between the erection rod bodies 5 between the horizontal rods 1. However, the horizontal rod 8 may be made to function as a horizontal displacement preventing rod that prevents the mounting object 12 from being laterally displaced.

Reference numeral 13 in the drawing denotes hooking grooves provided at both ends of the erection rod 5.

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, it can be folded in a small size when it is stored, convenient to carry, and can be a stable leg unit without wobbling, which is narrow in width. It is a very excellent folding stand leg device that can be mounted stably.

Further, according to the present invention, since the U-shaped connecting members provided at both ends are press-fitted from above into the erection rod body to hang the horizontal rod, the so-called one-touch operation can be performed easily and speedily. Since it is press-fitted from above, it is an excellent folding base leg device with high bearing strength.

Further, is the mounting rod of the erection rod also attached to the upper end of the support leg as a U-shaped connecting member, and the erection rod is press-fitted into the connecting member from above to be erected ?
Al, erection mounting erection rod also, because that allows all be mounted on the horizontal rod that spanned the erection rod into a series in the press-fitting operation of the one-touch, yet all above, the pedestals device folding the assembly working efficiency is extremely improved Become.
