の取扱いが面倒であつた。 Conventionally, as shown in Fig. 1, a commonly used tension device tower mounting bracket has a pivot that is inserted into a bearing protruding from the tip of the mounting bracket body, and a tension device is attached to the center of the shaft. The base of a device connecting piece (joint piece) is pivotally attached, and a support pin hole is bored at the tip of the connecting piece. However, if there is a distance (offset) 1 between the pivot and the support pin hole, a large bending moment is likely to be applied to the bearing portion, resulting in an increase in force. Further, in this case, the horizontal insertion of the pivot requires a nut portion at both ends to prevent loosening so that it does not come off during use, which is troublesome to handle.

である。 That is, in the present invention, the engagement groove for the support pin that is inserted vertically (orthogonally) into the connecting shaft that is inserted horizontally into the end of the main body of the mounting bracket that serves as the mounting seat is formed into a notch with a part below the axis of the shaft at most. A support pin inserted into the joint piece fitted to the connecting shaft is inserted into the engagement groove to prevent the connecting shaft from sliding out and to substantially raise the support point.

クレビスである。 1 is the mounting bracket body with the base as the mounting seat 1a,
Opposing bearing portions 2 are arranged on both sides of the distal end of the mounting fitting main body 1. Each bearing portion 2 has a shaft hole 3 laterally bored therein. Reference numeral 4 denotes a connecting shaft which has an engaging groove 5 for a support pin in the center and a semi-circular notch extending perpendicularly to one side that is below the axis position at most, and both ends of the connecting shaft 4 are simply connected to the shaft hole 3. Alternatively, the connecting shaft 4 may be of a type having a bolt head, a nut, and a locking pin at both ends like a conventional tightening bolt. Reference numeral 6 denotes a joint piece that passes through the connecting shaft 4 at the base and is interposed between the opposing bearing parts 2, 2, and a support pin hole 7 provided in the joint piece 6 is an engagement piece with at least a part thereof cut out in the connecting shaft 4. It is bored to match the groove 5. 8 is a support pin that is inserted into the engagement groove 5 of the connecting shaft 4 that matches the support pin hole 7 of the joint piece 6, and 9 is a parallel clevis that serves as a support piece that is attached to the support pin 8.

ある。 Here, the base of the joint piece 6 is fitted between the bearing parts 2, which are opposite to each other at the tip of the mounting bracket main body 1, and in this state, the connecting shaft 4 is inserted into the shaft hole 3 of one of the bearing parts 2. is inserted into the shaft hole 3' that passes through the joint piece 6 laterally, and its tip is inserted into the shaft hole 3 of the opposing bearing portion 2 to form a bearing. In this case, the positions of the support pin engagement groove 5 at the center of the connecting shaft 4 and the support pin hole 7 perpendicular to the shaft hole 3' of the joint piece 6 are made to match. Thereafter, the support pin 8 inserted through the parallel clevis 9 which is inserted into the joint piece 6 is inserted into the support pin hole 7 and the engagement groove 5 and connected to form the tower mounting bracket 12. After that, a double yoke 14 on which, for example, a tension insulator chain 13 is arranged is connected to the tip of the parallel clevis 9 attached to the joint piece 6.

なる。 In this state, in case of constant lateral vibration, the tensile insulator chain 1 is supported by the parallel clevis 9, which serves as one point support, and the support pin 8, which is vertically inserted into the joint piece 6, as the fulcrum.
The third side can swing. In this case, support pin 8
The mounting position is such that it fits into the engagement groove 5 cut out in the connecting shaft 4 and minimizes the offset l, so it does not apply too much moment to the connecting shaft 4 and is less likely to twist. The part 2 side can be downsized. Of course, the connecting shaft 4 having this engaging groove 5 is substantially constricted, but since the position of the engaging groove 5 is such that the support pin 8 is disposed in the front (in the tension direction), the engaging groove 5 is in a substantially constricted state. No direct tension load is applied to the joint groove 5, so that it can withstand strength. However, when the connecting shaft 4 itself slides sideways, since the support pin 8 is located within the engagement groove 5, the surface of the engagement groove 5 comes into contact with the support pin 8 and is locked. Sideways sliding (falling off) of connecting shaft 4
There is no. Therefore, the connecting shaft 4 can be supported by simply inserting it horizontally into the bearing portion 2.

え得る。 In addition, in the case of longitudinal vibrations caused by three-way jump, gear locking, blow-up from below, etc.
Since the parallel clevis 9 and the joint piece 6 are movable as a unit when the clevis is fitted, both ends of the connecting shaft 4 passing through the joint piece 6 laterally rotate (swing vertically) about the bearing part 2 as a fulcrum. . That is, the substantial pivot point of this longitudinal vibration is the main part (non-engaging groove) of the connecting shaft 4.
Since it rotates at , it is strong in terms of friction (no vertical vibration is directly applied to the engagement groove) and can withstand sufficient strength.

In the combination structure of the mounting bracket main body, the joint piece, and the support piece, an engagement groove portion is cut out in the center of the connecting shaft that passes through the joint piece horizontally, in which at least a support pin that passes vertically through the joint piece engages. By adopting the minimum offset structure, the lateral vibration characteristics are improved, and since the position of the connecting shaft is regulated by orthogonal support pins, there is no sideways sliding (falling off) of the connecting shaft, and the installation work of the connecting shaft is simplified. It is simple and ideal as a mounting bracket for increasingly larger sizes. Of course, since the offset is minimized, the overall structure of the mounting bracket can be made smaller. Incidentally, if necessary, additional nuts, locking pins, etc. may be provided at both ends of the connecting shaft (see the right connecting shaft portion shown in FIG. 2).
