Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a coupling device for detachably connecting two objects to be connected, and is particularly suitable for a case where one of the objects is subjected to a tensile force that causes the object to separate from the other due to an external force.

An example of a device receiving such a tensile force is a fixed pulley on which a wire rope under a tensile load is hung.
Conventionally, to secure a pulley or the like, the frame of the pulley was fixed to a beam, wall, frame, etc. using bolts, nuts, or wire.

In such an installation, the installation work is complicated, and it is not easy to change the position once it is installed.

In particular, a large number of pulleys are used to support the ropes used to open and close the thermal curtains in the greenhouse, and the greenhouse frame materials used to secure them come in a variety of sizes, both large and small. Freedom of removal was restricted.

The present invention was provided in order to eliminate the above-mentioned drawbacks, and its purpose is to provide a connector for removably connecting two connected objects, which can hold the first connected object. In this installation, a protruding flange is provided on the side of the opening end of a groove formed in a member, and two groove closing plates having side wall insertion grooves of the member are joined together at one end so as to be bendable. and a fixing member having a connecting female frame integrally formed on the rear wall of one of the closing plates, a male end portion consisting of a narrow neck portion and an engaging head that are fitted and locked in the female frame, and a second This is achieved by a coupling tool comprising: a support member in which a support portion for the connected body is formed;

Next, the present invention will be explained in more detail according to the embodiments shown in the diagram.

FIG. 1 shows an exploded perspective view of the connecting device according to the present invention before each member is assembled, and 1 is a mounting member with an opening in a concave groove 11 that can hold the first connected object P. Flange portions 12a and 12b protruding outward are formed in series at the lower end.

In the embodiment, since the object P to be connected is in the shape of a round pipe, a substantially U-shaped plate material having the shape of the member 1 was used for mounting, but it may be attached to a U-shaped, U-shaped or other shape depending on the circumferential shape of the object to be connected. The shape can be as follows.

Reference numeral 2 denotes a fixing member that integrally forms a concave groove closing plate 21 and a connecting female frame 22, and the two side walls 1a and 1b of the member 1 are inserted into the two closing plates 21 and 25 for the above-mentioned installation. The vertically elongated insertion grooves 21a, 21b, 25a, and 25b to be combined and fixed are formed at corresponding positions so as to open downward, and the two closing plates 21 and 25 are formed at their upper edges. They are integrally connected to each other so that they can be folded and unfolded at a connecting portion 26 that is shaped like a thin plate.

Further, a female frame 22 is integrally and continuously fixed to the rear wall of the closing plate 21 at a position inside the insertion grooves 21a and 21b.

This female frame 22 is provided in the shape of a substantially housing with a vacant space inside, and a peripheral wall through hole 22a communicating with the vacant space is bored on at least one side of the peripheral wall, and a rear wall is provided with a peripheral wall passage hole 22a that communicates with the vacant space. A wall through hole 22b is bored.

Although the two through holes 22a and 22b are opened on different faces of the frame wall, they are formed so as to be in integral communication with each other.

Reference numeral 3 designates a support member, the tip of which is a male end 31 consisting of a narrow neck 31a and an engaging head 31b that are fitted and locked in the cavity of the female frame 22, and the rear end is a It serves as a fixing part 32 for fixing the second connected body Q.

In the embodiment, a running rope Q1 is used as the second connected body Q.
shows a pulley that receives a tensile load, and its fixed part 32 is a pulley frame, but if it applies a tensile load that pulls the support member 3 in the direction of arrow m, the connected body Q can be attached to the pulley. Therefore, the shape of the fixing portion 32 is not limited to the illustrated pulley frame.

Further, the engaging head 31b is provided so as to slightly protrude like a flange at the tip of the narrow neck portion 31a.

As shown in FIG. 2, after positioning the narrow neck portion 31a and the engaging head 31b above the fixing member 2 in parallel with the upper circumferential surface of the fixing member, they are lowered in the direction of arrow n (g-).
The peripheral wall through hole 22a of the fixing member 2 is formed by

22b, and when the narrow neck portion and the engaging head are completely inserted into the empty space and are at the positions 31a and 31b, pull the support member 3 in the direction of arrow m, and the engaging head will be inserted into the female frame 22. It abuts and is locked on the inner surface 221 of the rear wall.

In addition, the through hole 22a consists of a narrow neck connecting part with a small width r and a joint head passage part with a wide radius, so that the joint head can be inserted into the empty room three times.
When it reaches the position 1b'', it has entered the lower part of this narrow r portion, and the left and right sides of the head 31b'' engage with the inner surface 222 of the upper wall of the cavity, so that it cannot slide upward and escape. (See Figures 2 and 3a).

Incidentally, if the outer peripheral shape of the narrow neck portion 31a of the male end portion 31 is made into a square shape as shown in FIG. 1, and the inner bottom surface 223 of the rear wall through hole 22b of the female frame 22 is formed into a flat surface, the connection shown in FIG. 2 can be achieved. The support member 32' can be fixed so as not to rotate about the horizontal axis X1 in this state.

Therefore, when supporting a pulley as in the embodiment, the running of the wire rope can be guided in a fixed direction, and twisting of the rope can be prevented.

Fig. 3a shows the support member 32 connected to the fixed member 2 so that the pulley is oriented vertically, and Fig. 3b shows the case where the pulley is connected so that the pulley is oriented horizontally. However, the above effects can be obtained.

If it is necessary to allow the supporting member 3 to freely rotate about the horizontal axis It is something.

In the illustrated embodiment, the shape of the joint head 31b is a square flange, but it is a modification included in the present invention that it may be made into a circular flange or a polygonal flange, regardless of the outer peripheral shape of the thin neck portion 31a. It is.

Therefore, in order to attach each member 1.2.3 according to the present invention, after fitting the sprout attachment member 1 so as to embrace the desired portion of the first connected body P, the both side walls 1a, 1b are fitted into the insertion holes 21aj and 21b respectively, and the fixing member 2 is pushed down from above and press-fitted, thereby holding the connected body P between the inner wall of the mounting member 1 and the front wall of the closing plate 21 of the fixing member. Fix tightly.

The connected state is shown in FIG.
5 is used in a polymerized state as shown by the solid line.On the other hand, in the case of the large diameter one P2, the closing plate 25 is folded upward in the direction of arrow S before being press-fitted and unfolded to the position shown by the two-dot chain line. 2
This is for press-fitting only one part.

In addition, when the two are overlapped and press-fitted, the closing plates 25 and 21 are vertically shifted due to frictional resistance with the connected body P□, and the closing plates 2
5 may not be press-fitted sufficiently, so it is also possible to prevent slippage by providing uneven strips 21cj25c etc. at key points of the joint breakdown so that the two can be press-fitted with exact overlap (see Fig. 4b). (See) 1. Next, to connect the support member 3, the support member 3 is engaged in the female frame 22 in the order described above from the solid line position shown in FIG. 2 to the position indicated by the two-dot chain line.

According to the present invention having the above-described structure and operation, it is easy to attach and fix the first connected body to the third connected body of different thickness, and the attachment position can be changed freely.

Furthermore, the mounting direction of the second connected body can be freely set by selecting the insertion direction of the support member 3.

Further, since each member 1.2j3 can be mass-produced by integral molding of hard plastic, it is possible to supply highly accurate and robust products at low cost.
