Abstract

PURPOSE:To increase lateral resistance and ensure safety at the time of use by positioning the bent section of a leg member flexed like a dogleg toward an expanding direction at an inner position, and externally bulging the lower section of the member. CONSTITUTION:Leg members 1 are jointed to one another with joints 2 connecting an intersection in cross type, and the members 1 are bent like a dogleg, with a position near the upper section thereof used as inflection points 11. The inflection point 11 of each member 1 is directed toward the arrangement center thereof. Also, a fixed joint 3 is fastened to the upper section of each member 1, while a ring type movable joint 4 is loosely coupled to the lower section of each member 1, so as to be vertically slidable thereon. In addition, a horizontal member connecting projection 5 formed as integral part of the joint 3 is provided on the top of each member 1. At the time of storage, almost all of the leg members 1 are positioned inside the joints 3 and 4, and a whole structure is made compact. Also, at the time of use, the lower section of the member 1 is inclined so as to bulge externally, and a horizontal force is converted to a downward component at a grounding section, thereby reducing a rolling motion.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leg device used for an assembled table used outdoors, a stove stand, and the like.

[0002]

2. Description of the Related Art Tables, stoves, and the like that are carried in camps and the like are assembled and made compact so that they are convenient to carry. Although various assembling means are known, the present invention particularly relates to a leg device in which the leg rod is formed to be expandable. A leg device in which this leg rod is formed to be freely expandable is disclosed in Japanese Utility Model Publication No. 4-26030, and specifically, the leg rods arranged at four positions in front, rear, left and right,
It is composed of a connecting body that connects each leg rod, and the connecting body is a cross-shaped part that pivotally connects the intersecting parts, and the upper end of each end of the connecting body is a fixed connecting part fixed to the upper part of the leg rod. The lower end of the connecting body is pivotally connected to the moving connecting portion which is vertically slidably mounted on the leg rod. The entire lever rod expands, and a fixed rod (horizontal rod) is attached to the metal fittings attached to the top of each leg rod.
Is connected so that the leg rods are fixed during use (when the leg rods are opened and expanded).

When used as a table, a foldable table plate is placed on the leg device for use, and a barbecue stove is placed for use as a stove stand.

[0004]

In the conventional leg device which can be expanded and contracted as described above, the connecting body becomes flat during use (when the lever rod is opened and expanded) so that the upper part of the leg rod is connected. Since it is not too much, the effect of so-called brace is not exerted, and the resistance force to the lateral force is small. For this reason, it sways with a little force, which is dangerous when used as a stove stand. Therefore, the present invention proposes an improvement to increase the lateral resistance.

[0005]

A leg device such as an assembled table according to the present invention has an upper end of a connecting body when a conventional rod is cross-shaped and is connected by a connecting body that pivotally connects the intersecting portions. Is pivotally connected to a fixed connection part fixed to the upper part of the leg rod, and the lower end of the connection part is pivotally connected to a ring-shaped movable connection part vertically slidably attached to the leg rod to expand the entire leg bar. A leg device in which the legs are formed freely, and the legs are connected to the horizontal rods that fix the distance between the rods when the rods are expanded and expanded. It is characterized in that the rod is bent in a dogleg shape in the direction of stenosis and the bent portion is positioned inward.

[0006]

[Function] When the leg rod is opened, the positions of the fixed connecting portion and the moving connecting portion pivotally connected to the end portion of the connecting body are always the same when seen from a plane, so that when they are stored (when the leg rod is closed). The most of its leg rods are inside (fixing direction) of the fixed connecting part and the moving connecting part, and the whole is made compact, and the lower part of the leg rod is projected outward when used (when the leg rod is opened and expanded). Thus, the lateral force is divided into the downward force at the ground contact portion, so that the lateral vibration is reduced.

[0007]

EXAMPLES Next, examples of the present invention will be described. The leg device is composed of a leg rod 1 and a connecting body 2. The leg rod 1 is bent in a V shape with a bending point 11 at a position close to the upper part, and is arranged at four positions in front, rear, left and right, and The bending point 11 of the leg rod 1 is directed toward the center of the arrangement of the leg rods, and each leg rod 1 has a fixed connecting portion 3 fixed to the upper part thereof and formed into a ring shape on the lower part thereof along the leg rod 1. A movable connecting portion 4 is slidably inserted in a vertically slidable manner, and a horizontal rod connecting projection 5 formed integrally with the fixed connecting portion 3 is provided on the top of the movable connecting portion 4.

The connecting body 2 is formed by connecting two connecting rods 21 and 22 in a cross shape and pivotally connecting the intersecting portions 23. The connecting rods 2 connect adjacent leg rods 1, and the upper portions of the connecting rods 21 and 22 are connected to each other. The end is pivotally connected to the fixed connecting portion 3, and the lower end is pivotally connected to the moving connecting portion 4. When the leg device is formed as a component on the table, the horizontal rod 6 is provided with a fitting recess 61 corresponding to the horizontal rod connecting projection 5 in addition to the leg device.
And a foldable top plate 7 is prepared. In order to assemble the table, the leg rod 1 is connected to the connecting rods 21 and 22 at the cross pivot joint portion 2.
Since the entire leg rods 1 arranged at the four positions are expanded with the rotation about 3, the leg rods 1 are opened and expanded.
The horizontal rod 6 is connected to the horizontal rod connecting projection 5 on the top of the leg rod 1 to prevent the expansion operation of the leg rod 1, and the top plate 7 is placed on the horizontal rod 6 for completion. .

Particularly, according to the present invention, when the leg rod 1 is expanded and expanded, the leg rod 1
Since the lower part of the is projected outward and the grounded part is erected obliquely, the lateral resistance is excellent. Further, in the closed state when stored, the bending point 11 is located inside, and even if the leg rod 1 is bent, it does not become an obstacle during storage.

The present invention is not limited to the above-mentioned embodiment, but can be applied to a six-legged leg device as illustrated in FIG. 5, but in that case, the central leg rod 1a other than the four corners is used.
Is a straight line without bending, and since the height of the bent leg rod 1 at the time of constriction is different from the height at the time of dilation, the central leg rod 1a
Corresponds to the height of the bent leg rod 1 at the time of expansion and expansion. Further, as a connection structure with the horizontal rod 6 for maintaining the open / expanded state, a means using the above-described known receiving metal fitting or any other means having a configuration for connecting and fixing the tops of the leg rods 1 is adopted. it can.

INDUSTRIAL APPLICABILITY As described above, the present invention is a leg device which is a connecting body that intersects in a cross shape and pivotally connects the intersecting portions, and connects adjacent leg rods so that they can be expanded and compacted during storage and transportation. In particular, the leg rod is bent outwardly,
This is a solution to the conventional drawback of easy wobbling in the lateral direction.
