Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a leg attachment device for a fishing stand used in rivers, banks, ponds, lakes, etc.

[Conventional technology]

The applicant first filed Utility Application No. 181459 (1981).
A leg attachment device for a portable fishing stand was devised as shown in Japanese Publications No. 95282 and Japanese Utility Model Publication No. 3-35104), but its complicated structure made it unsuitable for mass production, which had the disadvantage of making the product more expensive. .

[The problem that the idea attempts to solve]

The technical problem of the present invention is to provide a fishing stand leg attachment device that is extremely simple, can be mass-produced, and can be easily attached.

[Means to solve the problem]

The gist of the present invention will be explained in detail with reference to the accompanying drawings.

This fishing stand has pipe legs 2 hanging from the four corners of a square base plate 1, and a horizontal locking upper plate 3 and a horizontal locking lower plate 4 are attached to the four corners of the square base plate 1 through leg insertion gaps 5. Opposite leg attachment portions 6 are provided, leg insertion holes 7 are bored in this horizontal locking upper plate 3, and leg insertion holes 8 are formed in the horizontal locking upper plate 7 and corresponding horizontal locking lower plate 4. The locking hole edge 7a is bored slightly outwardly from the center of the leg insertion hole 7 of the horizontal locking upper plate 3 so as to have an oblique positional relationship, and the locking hole edge 7a is locked to the circumferential surface of the pipe leg 2. ,8a,
7b and 8b are formed at four locations on the upper and lower sides, and an escape groove 9 is formed on the edge of the lower leg insertion hole 8, and on the other hand, an outer peripheral upper end of the leg pipe 2 that is inserted into both leg insertion holes 7 and 8 is formed. A locking protrusion 11 that fits into the escape groove 9
The pipe leg 2 is inserted into the leg insertion holes 7 and 8 with the locking protrusion 11 aligned with the escape groove 9, and rotated to engage the locking protrusion 11 with the upper surface of the horizontal lower plate 8. This relates to a leg attachment device for a fishing stand, characterized in that pipe legs 2 are detachably attached to and hung down from leg attachment portions 6 at the four corners of a rectangular platform plate 1.

[Effect]

Insert the pipe leg 2 into the leg insertion holes 7 and 8 with the locking protrusion 11 aligned with the escape groove 9, and then
1 protrudes from the upper surface of the lower horizontal locking plate 8, and when the pipe leg 2 is slightly rotated, the locking protrusion 11 locks on the upper surface of the lower horizontal locking plate 8, preventing the pipe leg 2 from coming off. Therefore, the pipe leg 2 can be attached to the leg attachment part 6.

Next, by rotating the pipe leg 2 in the opposite direction and aligning the locking protrusion 11 with the escape groove 9, the pipe leg 2 can be pulled out and removed.

〔Example〕

The square base plate 1 is a folding member 1 made of aluminum.
a, 1b, and when these folding members 1a, 1b are folded, a trunk-shaped mobile box 12 is formed.
The diagram shows the case where

The leg attachment portions 6 are shown in the figure, being formed between the frame plates 13 and between the horizontal locking upper plate 3 and the horizontal locking lower plate 4 at both ends of the rectangular base plate 1.

The locking protrusion 11 may be pushed out by a press, or a separate object may be fixed thereto.

The pipe leg 2 is also shown using the same aluminum pipe and is height adjustable.

In the figure, 10 is a seat leg, 14 is a handle, and 15 is a connecting fitting.

[Effect of idea]

In this invention, the pipe leg 2 is configured as described above.
Insert the pipe leg 2 into the leg insertion holes 7 and 8 with the locking protrusion 11 aligned with the escape groove 9, and then
1 protrudes from the upper surface of the horizontal locking lower plate 4, and when the pipe leg 2 is slightly rotated, the locking protrusion 11 locks on the upper surface of the horizontal locking lower plate 4 and prevents the pipe leg 2 from coming off. , the pipe leg 2 can be attached to the leg attachment part 6.

In this way, the four pipe legs 2 can be attached to the four corners of the rectangular base plate 1 by simply inserting them into the leg insertion holes 7 and 8 and turning them.

In this case, the pipe legs 2 are provided with leg insertion holes 7 in a horizontal locking upper plate 3, a horizontal locking lower plate 4, and
In addition to being supported by the leg insertion holes 7 and 8, the leg insertion holes 8 below the leg insertion holes 7 and 8 are arranged in an oblique position with the leg insertion holes 8 slightly shifted outward. Since the locking hole edges 7a, 8a, 7b, and 8b are supported and locked, the rectangular base plate 1 can be firmly locked and supported by the pipe legs 2 without using any separate locking fittings, which is extremely convenient. The structure is simple and can sufficiently withstand the large load applied to the rectangular base plate 1.

On the other hand, to remove the pipe leg 2, rotate it a little to align the locking protrusion 11 with the relief groove 9, and then pull it to remove it, and removal is as easy as installation, which has excellent practical effects. It has the following.

Claims (1)

[Scope of utility model registration request] A fishing stand with pipe legs hanging from the four corners of a square base plate, and a leg mounting part in which a horizontal locking upper plate and a horizontal locking lower plate are placed opposite each other at the four corners of the square base plate with a leg insertion gap interposed therebetween. A leg insertion hole is bored in this upper horizontal locking plate, and a leg insertion hole is drilled in the lower horizontal locking plate corresponding to this upper horizontal locking plate. The holes are drilled slightly outward from the center of the pipe so as to have an oblique positional relationship, and locking hole edges that are locked to the circumferential surface of the pipe leg are formed at four locations (top, bottom, and outside). A relief groove is formed on the edge of the hole, and a locking protrusion that fits into the relief groove is provided on the upper end of the outer periphery of the leg pipe that is inserted into the leg insertion hole, and the locking protrusion is inserted into the relief groove. The pipe legs were inserted into the leg insertion holes in the correct position, rotated to lock the locking protrusions on the top surface of the horizontal locking lower plate, and the pipe legs were removably attached to the leg attachment parts at the four corners of the square base plate.
