Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a device for fixing a conduit for guiding a control wire to a suitable fixing member.

(Prior art) For example, in order to enable remote control of the trunk lock of a car from the driver's seat, the trunk lock release lever and the operating handle provided on the driver's seat are connected so as to interlock with each other. Control wires made of hard steel wire or the like are often used when connecting two members that are movable relative to a fixed member so as to interlock with each other.

When using such a control wire to connect two members so as to interlock with each other, the middle part of the control wire is connected to a flexible wire with each end fixed to a suitable fixed member near each movable member. It is common to insert the control wire into the conduit to guide it.

However, when each end of such a conduit is fixed to a fixed member, the operating range of the control wire is determined by the attachment position, and the operating range of the control wire is determined by the permanent expansion or contraction of the conduit. may change, so
It is convenient to be able to adjust its mounting position.

A conventional fixing device that fixes the end of a conduit to a fixing member in such a manner that the attachment position can be adjusted is disclosed in Japanese Utility Model Application Publication No. 142937/1983.

FIG. 1 shows a conventional device having almost the same configuration as disclosed in the above publication, in which 1 is a flexible conduit, 2 is a flexible conduit, and 2 is a flexible conduit that is movable in the axial direction within the conduit 1. This is the control wire inserted.

Each end 2a, 2b of the control wire 2 protruding from each end of the conduit 1 is connected to an operated member 3, such as a release lever for a trunk lock of an automobile.
and an operating member 4 such as an operating handle provided on a driver's seat, respectively, so that both members 3 and 4 are interlocked with each other.

One end of the conduit 1 is fixed by a fixing device 5 to an appropriate fixing plate 6 near the operated member 3 so that the mounting position can be adjusted.

In this fixing device 5, a long hole 8 substantially parallel to the axial direction of the control wire 2 is bored in a proper position of a holding member 7 having a grip part 7a that grips the end of the conduit 1, and the long hole 8 is inserted through the long hole 8. The holding member 7 can be fastened to the fixing plate 6 with a fixing bolt 9, and a bent piece 7b connected to one end of the holding member 7 is bored in the fixing plate 6. The control wire 2 is engaged with a long hole 10 substantially parallel to the axial direction of the control wire 2.

The other end of the conduit 1 is fixed directly to a suitable fixing plate 11 or by means similar to the fixing device 5, so that the mounting position can be adjusted.

According to the conventional fixing device 5 as described above, the holding member is fixed by loosening the fixing bolt 9 and sliding the bent piece 7b relative to the elongated hole 10 and the elongated hole 8 relative to the fixing bolt 9. 7 in the axial direction of the control wire 2, and then tightening the fixing bolt 9 again, the conduit 1
The mounting position of the end of the holding member 7 can be easily adjusted, and the engagement between the bent piece 7b and the elongated hole 10 prevents the holding member 7 from rotating around the fixing bolt 9.
The holding member 7 does not rotate unexpectedly, and the conduit 1
It has the advantage of being able to securely fix the ends of the.

On the other hand, in this conventional device, if a strong external force is applied in the axial direction of the conduit 1, there is a risk that the holding member 7 will shift in the axial direction of the control wire 2, and with this shift, the fixing bolt 9 will loosen, causing the above-mentioned problem. There is a drawback that the displacement of the holding member 7 is further promoted.

In particular, in such a device, when the control wire 2 is pulled in the direction of arrow 12 in FIG. Since the holding member 7 is easily displaced in the axial direction of the control wire 2, and the pulling or pushing motion of the control wire 2 is repeated many times, even if the holding member 7 is slightly displaced each time, By repeating them,
There is a great possibility that the positional shift will become large or that the fixing bolts 9 will become loosened.

(Purpose of the invention) The present invention is a method for fixing a conduit for a control wire that can reliably prevent the fear of displacement of the control wire in the axial direction of the holding member in the conventional device as described above with a simple structure. The purpose is to provide a device.

(Structure of the invention) The present invention provides a fixing plate with a holding member that grips a proper position of a conduit through which a control wire is movably inserted in an axial direction, and a holding member that grips a proper position of a conduit through which a control wire is movably inserted in an axial direction. A known structure is provided in which a locking piece is provided on either one of the arm extending from the holding member and the fixing plate, and the other is provided with a locking piece that is fastened by the fastening means. The present invention is characterized by the addition of a novel structure in which a plurality of engaging teeth are formed, each of which allows the locking piece to be engaged and disengaged by appropriately rotating around the attachment portion.

(Effects of the invention) With the above-described configuration, the present invention has the structure described above, so that when a large external force is applied in one direction, which is the axial direction of the conduit, the edge of the engagement hole drilled in the fixed plate an engaging portion between the engaging teeth and the locking piece;
There is an advantage that the arm portion acts as a tension rod between the portion of the holding member that is fastened by the fastening means, and can reliably prevent the holding member from shifting in the same direction.

Therefore, in consideration of the strong directionality of the device of the present invention against external forces, control can be achieved by fixing both ends of the conduit to fixed members with the device of the present invention arranged symmetrically to each other. Even when the wire is violently pulled or pushed, there is no fear that the end of the conduit will shift or the fastening means will loosen, and it is possible to provide sufficiently durable support for the conduit.

Furthermore, although the device of the present invention is fundamentally different in principle from the conventional device shown in FIG. 1, it is almost the same in terms of structural complexity, and has the advantage of being simple and inexpensive to manufacture.

(Example) Hereinafter, the present invention will be explained based on an example shown in each figure after FIG.

In FIGS. 2 and 3, one end of a conduit 1 into which a control wire 2 similar to that in FIG. 1 is movably inserted is fixed to a stopper 16 having enlarged diameter flanges 16a at both ends. Fixing device 17
The upper part of the holding member 18 has a U opening facing inward.
A gripping portion 19 having a shape portion 19a is formed, and the flanged stopper 16 is held in the gripping portion 19.
By fitting the conduit 1 into the handle 19, one end of the conduit 1 is clamped to the grip 19.

The holding member 18 is formed with a long hole 18a that is substantially parallel to the control wire 2 near the grip portion 19, and the washer 22 and spring washer 23 are inserted through this long hole 18a so that the holding member 18 is overlapped. It is attached to the fixing plate 24 by a fixing bolt 25 screwed into the fixing plate 24.

At the lower part of the holding member 18, there is a
An arm portion 18b extending obliquely downward on the right side in the figure is provided, and a locking piece 18c formed by bending the end inward is provided at the end of the arm portion 18b, and the locking piece 18c is inclined upwardly to the right. It is formed.

The fixing plate 24 has an elongated hole 26 formed therein, in which the locking piece 18c is movable within an appropriate range, and is substantially parallel to the grip portion 19. A plurality of engagement teeth 27, such as saw teeth, for example, are formed on the inner edge 26a on the side opposite to the inner edge 26a.

The locking piece 18c is inserted into the engagement tooth 27 at the required position.
By tightening the fixing bolt 25 after engaging with the conduit 1 clamped to the holding guard 18
The mounting position is adjusted along the direction of the control wire 2.

An operating member 4 and an operated member 3 are engaged with each end of the control wire 2, as in FIG. 1, and by moving the operating member 4 in the direction of arrow 14, the upper grip part 1
Similar to the conventional example, a reaction force in the direction of arrow 12 is generated at point 9.

As a result, the holding member 18 is attached to the fixing bolt 25.
However, since the locking piece 18c of the holding member 18 is engaged with the engagement teeth 27 of the fixed plate 24, the rotation of the holding member 18 is is definitely prevented. Further, when the locking piece 18c is in a state of falling between the adjacent left and right engaging teeth 27, the arm portion 18b exerts a tensioning action, so that the holding member 18 is prevented from shifting in the left-right direction. There is.

In the above embodiment, the arm portion 18b of the holding member 18 is inclined diagonally downward to the right from the fixing bolt 25, that is, on the operated member 3 side and on the side opposite to the control wire 2. However, the direction of inclination of the arm portion 18b is not necessarily limited to this.

For example, as shown in the arm 18d indicated by a chain line, the arm 18d is directed diagonally downward to the left from the fixing bolt 25, and a long hole 28 is inserted into which the locking piece 18e at the end of the arm 18d is inserted.
Even if the locking piece 18e of the arm portion 18d is engaged with the engagement tooth 29 formed on the inner edge 28a of the upper part of the elongated hole 28, the same position as in the previous embodiment can be obtained. It is possible to prevent slippage and rotation.

Even if the arm portions 18b and 18d are extended obliquely upward from the fixing bolt 25, they can perform the same function as described above.

Further, in the above embodiment, the locking piece 18c is provided on the holding member 18, and the engaging teeth 27 that engage with this are provided on the fixed plate 6, but conversely, the locking piece 18c is provided on the fixing plate 6.
The same effect can be obtained by providing the fixing plate c on the fixed plate 6 and the engaging teeth 27 on the holding member.

When operating the control wire 2, no counterclockwise rotational force acts on the holding member 18, but if the conduit 1 is pulled in the opposite direction to the arrow 12 for some reason during maintenance or inspection of the device, the holding member 18 is held There is a possibility that the member 18 rotates counterclockwise and the engagement between the locking piece 19c and the engagement tooth 27 becomes disengaged.

Means for preventing this problem will be explained based on FIG. 5.

In FIG. 5, a locking member 31 is provided overlappingly between the holding member 18 and the fixing plate 24, and a long hole 32 formed in the locking member 31 is parallel to the control wire 2. , is loosely fitted into the fixing bolt 25.

Arm portion 31a provided at the lower end of the lock member 31
A stepped portion 31b protruding into the elongated hole 26 is provided at the end of the
is formed, and its upper edge 31c is formed with a long hole 26
It is in contact with the upper inner edge 26b of. Stepped portion 31b
An inclined edge 31d whose lower end edge is raised toward the operated member 3 side is formed at the lower part of the slanted edge 31d.

After the holding member 18 that clamps the conduit 1 is set at the required position as shown in FIG. Since the inclined edge 31d of the locking member 31 presses the upper part of the locking piece 18c, the holding member 18 is prevented from rotating counterclockwise in FIGS. 4 and 5, and the locking piece 18
d and the engagement teeth 27 can be reliably maintained.
