Description

Link unit

The present invention relates to a board body in which nails and screws, such as a table top of a honeycomb structure core material, a table top of a table, or a shelf of a rack, cannot function, and a link used for assembling the foot and the bracket is used. unit.

A generally combined table, table or shelf plate, etc., as shown in the following Patent Documents 1 to 3, uses a scaleless wood, plywood and integrated wood in which the feet or pillars of the object plates are assembled. The pedestal mold used is fixed by nails or assembly screws. However, in order to achieve weight reduction and cost reduction, a honeycomb core material is used in the plate body of the aforementioned aluminum thin plate and cardboard, and a smooth plate is attached to the upper surface and the lower surface thereof. Since the nail or the assembly screw cannot effectively function on the pedestal mold of such a smooth plate, it is difficult to stably assemble the foot or the pillar, and therefore the demand for the dedicated joint unit of the foot or the pillar can be securely assembled on such a smooth plate. It will gradually increase.

The assembly base 2 has an assembly means 2a, and the assembly means 2a assembles the foot C to the plate body A. The fixing base 3 is inserted into the assembly hole a provided in the plate body A, and the assembly seat 2 is assembled to the fixing base 3. The plurality of fixing members 4 are for inserting and fixing the fixing base 3 into the assembly hole a, and are protruded outward in the direction of the fixing base 3.

In the embodiment of the figure, the assembly seat 2 is composed of a flange portion 2b, a base portion 2c, a fixing portion 2d, a male screw portion 2e, a female screw portion 2f, and a six The corner hole is composed of 2g. The flange portion 2b is formed in a disk shape, and the base portion 2c is also in the shape of a disk and is disposed below the flange portion 2b. The fixing portion 2d is formed in a flat quadrangular shape and is disposed below the base portion 2c. The 2e-series connecting portion 2d is provided, and the female screw portion 2f is provided in the axial direction of the male screw portion 2e, and the flange portion 2b, the base portion 2c, and the fixing portion 2d are penetrated, and is also an embodiment of the assembling means 2a. The hexagonal hole 2g is a hexagonal planar shape and is provided at the entrance of the female screw portion 2f and is used for bolting. Further, the flange portion 2b and the base portion 2c may be combined into a single flange portion 2b, and the flange portion in this aspect includes both the flange portion and the base portion. Further, in the embodiment, the assembling means 2a is exemplified by the female screw portion 2f, but it is not intended to limit the present invention, and may be an engaging means for assembling the engaging portion for the foot.

Further, the fixing base 3 is formed in a substantially disk shape having a thickness, and is provided with a quadrangular assembling hole 3a for inserting and fixing the fixing portion 2d of the assembling seat 2 in the axial direction of the center portion, and is radially disposed at Around the assembly hole 3a, the plurality of storage chambers 3b are disassembled from the upper portion and the outer portion of the opening in the outer direction. While the housing chamber 3b is provided with a plurality of fixing members 4 that can be freely extended and contracted outward, each of the fixing members 4 can be slid to the outer direction of the receiving chamber 3b by the elastic means 5, wherein the elastic means 5 is configured It is composed of a plurality of compression springs of the respective fixing elements 4.

Each of the storage compartments 3b is provided with a locking portion 3c on the outlet side in three directions thereof, and the fixing member 4 is provided with an inclined portion 4a on the front end side thereof and a card having three outlets in the engaging and receiving chamber 3b on the rear end side. The splicing piece 4b, the fixing elements 4 housed in the respective accommodating chambers 3b are pressed by the elastic means 5 to prevent Outward direction is outstanding. Each of the fixing members 4 is further provided with a receiving hole 4c for accommodating a part of each of the elastic means 5.

The assembly base 2 is configured such that the fixing portion 2d is inserted and fixed to the assembly hole 3a of the fixing base 3, and the male screw portion 2e is bolted and fixed by the nut 6, so that the fixing base 3 is fixed non-rotatably. A plurality of locking projections 2h and 2i are provided below the flange portion 2b and at the lower end side of the male screw portion 2e. At this time, the hexagonal hole 2g for tamping provided in the flange portion 2b is such that the nut 6 is bolted by a hexagonal wrench.

Therefore, in the above-described connection unit 1 of the present invention, when the combination of FIG. 1 and FIG. 2 is upright, as shown in FIG. 7, the male screw portion 2e is pressed from the vertical direction toward the assembly hole a provided in the plate body A. The depth of the assembly hole a corresponds to the length of the connection unit 1 and the width of the assembly hole a corresponds to the outer diameter of the fixing seat 3, and each fixing element 4 will abut against the entrance of the assembly hole a and resist the elastic force of each elastic means 5. Pressing into the respective receiving chambers 3b, the resistance and the pressing force received at this time, the front end of the male screw portion 2e reaches the bottom of the assembling hole a, and the locking projection 2h protrudes into the bottom of the assembling hole a. Further, the locking projection 2i of the flange portion 2b is further protruded into the smooth plate b of the plate body A, so that the coupling unit 1 can be stably fixed to the assembly hole a of the plate body A. In addition, if the bottom of the core material is a non-smooth plate, the core material is used instead.

Then, as shown in FIG. 7, the assembly bolts c assembled to the front end of the leg portion C are screwed to the female screw portion 2f of the assembly tool 2 of the assembly base 2, and the assembly of the leg portion C with the plate body A is completed. Similarly, the other leg portions are also assembled to the coupling unit 1.
