The connector includes a body 2 provided with: an insertion hole 5 for a wire and a holding hole 6 for an outer cylinder 9 in the shaft center thereof; and a lock screw 7 for fixing the outer cylinder thereto and an adjustment screw 3 for changing both end positions of the outer cylinder.

Description

  The present invention relates to a connector used for a wire.

  A typical bicycle that drives a braking tool such as a brake via a wire using an operating tool such as a lever is a bicycle. As a connection method, a method is generally used in which a wire is passed through the outer cylinder, and one is connected to the operating device and the other is connected to the braking device. At this time, since both ends of the outer cylinder are merely inserted into the connecting tool arranged near the operating tool or the braking tool, the external cylinder may come off from the connecting tool by some external force.

  In principle, in a state where one end of the outer tube is fixed by inserting a wire through the outer tube having both ends fixed, the wire is loosened when the distance between both ends of the outer tube is increased, and the wire is pulled when the distance is reduced. In other words, when the outer cylinder comes off and both ends change position, the tip of the wire changes, and when both ends are fixed to the operating tool and the brake, the pulling amount of the brake changes, and as a result, the effect of the brake is affected. Will give. Conversely, if the positions of both ends of the outer cylinder are changed, the amount of movement of the wire tip when the wire is intentionally pulled can be changed.

From the above background, in the connection tool used for the wire drive, a connection tool having a function of changing both end positions without removing the outer cylinder is effective.
Examples of such outer tube connection tools include those disclosed in Utility Model Document 1 and Utility Model Document 2.
Both the utility model document 1 and the utility model document 2 describe a connector for a bicycle lever. The outer support 13 of the utility model document 1 and the support 3 of the utility model document 2 are also inserted with an outer. Although the description is not found, the support 3 of the utility model document 2 is assumed to have an adjusting screw when judged from the drawing. However, there is nothing to prevent the outer cylinder from coming off.

  The present invention has been made in order to solve the problems of the conventional method, is for an outer cylinder having caps at both ends, provided with a wire insertion hole and an outer cylinder holding hole at the axis of the body, A connecting screw for the outer cylinder is provided, in which a lock screw for preventing the outer cylinder from coming off is provided near the cap, and an adjusting screw for changing the positions of both ends of the outer cylinder is provided at the tip of the body.

Claim 1 is a connection tool for an outer cylinder for a wire having caps at both ends, wherein an insertion hole for a wire and a holding hole for the outer cylinder are provided in series at an axis of a body provided with an adjusting screw at a tip thereof, In a state where the cap is inserted into the holding hole in the body, the lock screw is attached to a position where the rear end of the cap and the outer diameter of the lock screw are close to each other to form a connecting tool. A connecting tool for inserting the tube, rotatably fixing the lock screw, and adjusting the distal end position of the outer tube with the adjusting screw.
As a result, the amount of wire pulled can be kept constant without the outer cylinder coming off, and the looseness of the wire can be easily adjusted with the connector.

According to a second aspect of the present invention, there is provided a connecting tool in which the amount of protrusion of the lock screw toward the holding hole is substantially equal to the thickness of the cap.
As a result, the outer cylinder is not pressurized by the lock screw, and the outer cylinder is not twisted even when the connector is turned, so that the wire can be adjusted without loosening the lock screw.

  The connecting tool of the present invention has a simple and inexpensive configuration in which the number of parts is minimized.

Front view of the connection tool 1. Right side view of FIG. FIG. 1 plan view Front view showing a state in which a wire and an outer cylinder are attached to a connection tool A diagram showing a state where the connecting tool is attached to the operating tool and the braking tool, and the wire and the outer cylinder are mounted.

Hereinafter, embodiments of the present invention will be described.
First, the connection tool will be described with reference to FIGS.
The connecting tool is provided with an adjusting screw 3 and a lock nut 4 for the adjusting screw on the left side, and a holding hole 6 for holding the outer cylinder and a locking screw 7 for fixing the outer cylinder 9 on the right side. At the center of the hole, the wire 8 is penetrated to the left through the insertion hole 5 of the wire 8. The position and the size of the holding hole 6 are such that the diameter of the holding hole 6 is such that the cap 10 of the outer cylinder 9 can be inserted. The lock screw 7 has a small gap between the outer diameter of the lock screw and the rear end of the cap when the tip of the cap 10 is in contact with the front wall 6a of the holding hole 6. At the provided position, the tip of the lock screw is attached by protruding inward from the side wall 6b of the holding hole 6 by the thickness of the cap.

Next, a state in which the wire and the outer cylinder are inserted into the connecting tool of the present invention will be described with reference to FIG.
FIG. 4 is a view showing a state in which the outer cylinder 9 is inserted from the right side of the connection tool, the lock screw 7 is completely tightened, and the wire 8 is passed through the outer cylinder 9 and the insertion hole 5.
In this state, the outer cylinder 9 is firmly held by the holding hole 6 attached to the body 2, the outer diameter of the lock screw 7 is close to the rear end of the cap 10, and the tip lightly contacts the outer peripheral surface of the outer cylinder. It is in a state where it has been done. As a result, it is possible to prevent the outer cylinder 9 from coming off in the right direction, and to support the adjusting cylinder 3 so that it does not twist even when the adjusting screw 3 is turned.

Finally, a state in which the connecting tool of the present invention is attached to the operating tool and the braking tool and the wire and the outer cylinder are inserted will be described with reference to FIGS.
As shown in FIG. 5, after the operating tool 50 is fixed to the handle 40, the adjusting screw 3 of the connecting tool 1 a is screwed into the screw hole 53 of the connecting tool bracket 52 of the operating tool, and is fixed with the lock nut 4.
Further, as for the braking tool 60, a brake mechanism described in Japanese Patent Application No. 2014-192043 in which the brake shoe 61 presses the wheel 31 is attached to the fixed caster 30, and the connecting tool bracket 62 of the braking tool 60 is operated in the same manner as the operation tool. The adjusting screw 3 of the connecting tool 1b is screwed into the screw hole 63 of FIG.
Then, in the above-mentioned state, the lock screw 7 of the connecting tool 1a attached to the operating tool 50 is loosened and inserted into the holding hole 6 until one end of the outer cylinder 9 is abutted, and the lock screw is tightened. The other end of the outer cylinder is also inserted into the connector 1b attached to the connector 1b, and is fixed with the lock screw 7.
At this time, the tip shape of the lock screw may be rounded depending on the material and size of the outer cylinder.
Thereafter, the end of the wire 8 is fixed to the lever 51 attached to the operating tool 50, and the other end is passed through the insertion hole 5 of the operating tool 1a, the outer cylinder 8, and the operating tool 1b of the braking tool 60 in this order. It is fixed to the tool 60.
In this state, when the lever 51 is pulled, the amount of the pull is transmitted to the brake device 60 side via the wire 8 and becomes the pull amount for operating the brake device 60. When the wire 8 is extended, this pull amount is used. However, when the outer cylinder 9 comes off from the connection tool 1, it becomes excessive because a loss corresponding to the amount of elongation occurs, and conversely, it causes malfunction of the brake.
This will be briefly described with reference to FIGS. 4 and 5. The outer cylinder 9 has a length corresponding to the path, and is fixed at both ends with the connecting tool 1 a on the operating tool 50 side and the connecting tool 1 b on the braking tool 60 side. A wire 8 is inserted through the end and both ends are fixed to the operating tool and the braking tool, respectively, without loosening.
However, the wire 8 is stretched from the above state while using the wire, and the wire 8 is loosened, or the outer cylinder 9 is detached from the connection tool 1a or the connection tool 1b by an external force such as gravity or vibration.
In the connecting device of the present invention, the lock screw 7 stops the cap 10 attached to the tip of the outer cylinder 9 to prevent the cap 10 from coming off, and the looseness of the wire 8 can be tightened by the adjusting screw 3. For example, the wire is pulled toward the outer side by loosening the adjusting screw 3 attached to the connecting tool 1a in FIG. 5 and moving the connecting tool 1a in the direction of the outer cylinder 9, so that the adjusting screw is connected to the wire. Loosening by the amount of slack will eliminate slack.
