Abstract

PURPOSE: To reduce machining cost by forming a plurality of projecting parts in one of two block bodies in which a vertical through hole and a half-split horizontal through hole on an inner face are formed respectively, and recessed parts fitted in the projecting parts in the other thereof and integrating both of them by screws. CONSTITUTION: A block body A5 having a vertical through hole 1, a half-split horizontal through hole 2, four conical projecting parts 3, and a screw hole 4 passes through a vertical pole 6 and is fixed at an arbitrary height. Moreover, a block body B10 having a vertical through hole 1', a horizontal half-split through hole 2', recessed parts fitted in the projecting parts 3, and a through screw hole 9 passes through the pole 6 downward. Next, a horizontal pole 11 is put in the through hole 2, and blocks 5, 10 are joined mutually by a screw 12. They are formed by slightly deviating the center of the through holes 2, 2' and are fixed and integrated with a pole 11 by the screw 12. Consequently, it is possible to provide a degree of freedom for changing dimension and reduce machining cost required for assembly and transportation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a locking jig for supporting and assembling display poles, construction scaffolding poles, and the like.

(Prior technology) A. For display use, there is a hanger type in which the pole is processed into an inverted shape, a type in which the pole is assembled using a universal joint, a type in which a slit is made in the support and a bracket is attached to the slit, and B. For various construction scaffolding frames, there are types that are assembled by threading the ends of each pole and connecting them with various elbows.

(Problems to be solved by the invention) A. Displays lack the flexibility to adapt to the wide variety of dimensions of displayed items, and the design of the entire display in free space is also problematic. . Furthermore, it had a strong sense of ready-made concepts and was inferior in design. If a locking jig is used to cover these points, the structure will be complicated and the processing cost will be high. It requires threading on the edges and man-hours for cutting to appropriate dimensions. Another major problem is that it is difficult to scale it to an arbitrary size.

[Means for solving problems]

The present invention has been made to solve the above problems, and includes a block body A having a vertical through hole, a halved horizontal through hole, a plurality of convex portions, and a screw hole on the inner surface; A block body B having a vertical through hole and a half horizontal through hole on the inner surface, a recess that fits into the convex part of the block body A, and a through screw hole is joined to match, and a pole is inserted into each through hole. The present invention relates to a pole locking jig characterized in that both block bodies AB are fixed with screws and integrated.

The shape of the assembled and integrated block body according to the present invention is as follows:
The preferred material is iron, iron alloy steel, A-shaped, etc.
Practical materials include A-cross alloy, Ti, Ti alloy, and plastic. The shape of the half-split horizontal through-hole and the vertical through-hole is not limited to whether it depends on the pole shape or is generally circular, square 1, etc., and the hole diameter may be the same diameter or different diameters. The shape of the plurality of concavo-convex portions provided on the inner surface of each block is not particularly limited, and conical or pyramidal shapes are often used. Further, it is more preferable that the center of the half-split horizontal through-hole on the block body A side used in the present invention and the center of the half-split horizontal through-hole on the block body B side used in the present invention are shifted by about 0.5% to 5% of the pole diameter value. .

The purpose of slightly shifting the centers of the block bodies A and B in this manner is to strengthen the support and fixation of the pole to be locked. If the center deviation is less than 0.5%, the supporting and fixing of the locking pole may be insufficient. If it becomes 5% or more,
This is not preferable because the level difference in the half-split horizontal through-hole becomes large, which may impair the design.

Incidentally, positioning screw holes may be provided on the side surface of the block body AB, A, B, or both block bodies AB.

(Function) Next, we will discuss the function of the pole locking jig of the present invention in Section 1.2.
．． This will be explained using Figure 3.

Vertical through hole (1) and half horizontal through hole (2) and 4 on the inner surface
A block body A (5) having a conical convex portion (3) and a screw hole (4) is provided upward and a vertical pole (6
) through the hole and fix it to the positioning screw hole (7) at an arbitrary height using the screw (8). On the other hand, in order to penetrate downward into the vertical pole (6), a vertical through hole (1') and a halved horizontal through hole (2') on the inner surface and 49 of the block body A (5) are formed.
A concave portion (1) is fitted into a convex portion (3) having a conical shape.
4) and a block body B (10) having a through screw hole (9).
At the same time, a horizontal pole (11) is placed in the lower half-split horizontal through-hole (2), and the block body AB (5, 10) is joined. Both block bodies AB (5, 10) are perfectly horizontally aligned due to the effect of the convex and convex portions, and at the same time, the horizontal pole (11) is aligned with the horizontal half-split horizontal through hole (2) provided in block body AB (5, lO). , 2') with a slight center deviation (15
) is sandwiched by a partial joint of the circumferential surface. In this state, the through screw hole (9) provided in the block body B (10)
), for example, by screwing the screw (12) into the screw hole (4) of block body A (5), both block bodies AB (5
, 10) are fixed and integrated, and one pole (6, 11) is supported and fixed. In this way, the locking jig (13) for the pole of the present invention
can be completely freely installed at any height and any number of horizontal poles (1
1) and the installation of the vertical pole (6) is possible. In addition, the horizontal pole (11) can be connected freely through the half-split horizontal through-holes (2, 2') without threading the pole end, and if the locking jig (13) is used in multiple stages, freely vertical,
It is possible to increase the number of horizontal poles. In addition, since the vertical hole is provided through both blocks (5° 10) of one piece, it has strength and also has the effect of improving safety.

(Example) (1) Vertical through hole diameter 20 mm as a display pole locking jig. lφ The centers of the upper and lower half-split through holes are shifted by 0.3 mm 20. A block body A has a half-cut through hole of lφ, four conical protrusions each having a diameter of 2φ and a height of 3 mm, and a block body B has a concave portion that fits into the block body A, and a vertical hole of 20φ whose surface is treated with Ni plating is used. Insert a horizontal pole through the W4 hole and integrate both blocks with a screw with a diameter of 4 mm and a length of 30 mm.Both assembled blocks are made of AM and have a length of 40 mm, a width of 40 mm, and a length of 80 mm. It has a prismatic shape. This locking jig was used for display in a department store. The block body B was fixed to the side surface with a positioning screw having a diameter of 3 mm. A perspective view of this embodiment is shown in Figure 4.
Shown in UA.

(2) Regarding the locking jig for the poles of the construction foot frame, the integrated block body is made of 13cr steel and has a length of 60 mm.
It has a prismatic shape with a length of 60 mm and a length of 120 mm, and the diameter of both prize holes is 4.
A stainless steel vibrator with a 0.1φ pole diameter of 40φ was used, and both block bodies were fixed with screws having a diameter of 10 mm and a length of 50 mm. There is a 5mm positioning screw on the side of block B.
It was fixed at φ. A foot frame with a height of 7 m and 110 m and a width of 1 m was assembled using the locking jig. The results of these implementations are summarized in Table 1.

Itinerary margin table -1 (Effects of the invention) Since the present invention has the above-mentioned configuration, it has excellent functional design for display in a free space, and the novelty of its geometric simplicity makes it appealing to customers. It received high praise. Furthermore, the effects obtained by the locking jig of the present invention are immeasurable, such as increasing the display volume with greater freedom in changing dimensions, reducing assembly man-hours, costs, and transportation man-hours, and ensuring safety.
