Description

  The present invention relates to a wire tension adjuster, and more particularly to a wire tension adjuster that can be assembled in a state in which a wire is tensioned by a bolt fastening method.

  In general, a window regulator or a door module provided with a motor is provided with a wire for supplying power and operating it by sending a control signal, and the wire is maintained in a tensioned state. For this reason, the wire is installed by applying tension using a window regulator or a door module part which is a component laid out together.

  The operation for forming the wire layout is usually performed manually by an operator or using a suitable separate tool.

  FIG. 4 shows an example in which the worker performs the wire work directly by hand. In this example, the worker (W) pulls the wire 200 lined up in the module 100, hangs on the protruding pulley 110 portion of the module 100, and maintains the wire 200 in an appropriate tension (Tension).

  FIG. 5 shows an example in which an operator works using a separate tool. In this example, the operator pulls the wire 200 arranged in the module 100 with a separate tool (T) and hangs it on the protruding pulley 110 portion of the module 100, thereby applying an appropriate tension to the wire 200 and maintaining it. Let

  In this way, grasping and stretching the wire directly by hand will force the operator to perform troublesome and inconvenient work, and the work of the operator pulling the wire strongly using a separate tool, The risk of damaging the wire is increased.

  FIG. 6 shows an example in which the wire is damaged (K) as a result of such an operation. The damage (K) of the wire 200 is frequently caused by the tip (t) of the tool (T) particularly when a separate tool (T) is used as shown in FIG.

  However, such damage (K) of the wire 200 does not occur at the time of assembling work, but often occurs during operation after installation, and there is a limit that the presence or absence of damage (K) cannot be checked during the work. .

  As for the wire of the window regulator, there are reports of wire tension adjustment [Patent Document 1], wire end holding [Patent Document 2], wire winding device [Patent Document 3] and the like.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a wire tension adjuster capable of facilitating the assembling operation of an operator and completely eliminating the possibility of wire damage that occurs when the operator does not know during the assembling operation. It is to provide.

  The wire tension adjuster of the present invention made to achieve the above object includes a bolt shaft inserted into a bolt hole opened at a wire position end of a wire clamp in which wires are arranged, and extends from the bolt shaft to the bolt hole. It is configured to have a wire shaft on which a wire is wound, positioned on a wire step surface that forms a space opened by being connected to the wire position end when inserted.

  The bolt shaft is further formed with a head having a diameter larger than that of the bolt shaft, and the wire shaft is formed with a through hole through which the wire can be passed.

  The end portion of the wire shaft is fitted into a groove formed in the wire position end portion of the wire clamp, and the end portion of the wire shaft is fitted into the groove and is fixed so as not to rotate.

  A screw is formed on the outer peripheral surface of the bolt shaft, a screw is also formed on the inner peripheral surface of the bolt hole opened at the wire position end, and the bolt shaft is coupled to the bolt hole with the screw.

  The wire tension adjuster of the present invention can be coupled by a bolt fastening method in a state where a wire is wound and tension is applied, and the assembling process of the worker is facilitated, and the worker is not aware of the assembling work. The possibility of wire damage that may occur can be eliminated.

  Further, by applying tension to the wire by winding the wire and maintaining the wire, it is possible to prevent occurrence of abnormal wire noise due to slackening of tension that occurs after operation. Furthermore, breakage of the wire is eliminated, and the merchantability of the vehicle can thereby be improved.

It is a block diagram of the wire tension adjuster which concerns on this invention. It is a figure which shows the wire layout assembly using the wire tension adjuster which concerns on this invention. It is a figure which shows the wire layout assembly using the wire tension adjuster which concerns on this invention. It is a part of conventional wire layout assembly work. It is a part of conventional wire layout assembly work. It is an example of the wire damage state by the conventional wire assembly operation.

  Referring to FIG. 1, the wire tension adjuster of the present invention comprises a bolt type adjuster bolt 1, and the adjuster bolt 1 is attached to a wire clamp 10 and can be fixed in a state where tension is applied to a wire 20.

  Here, the wire clamp 10 is provided in a window regulator or a door module part that needs to be attached in a state where the wire is in tension, and in all other vehicle parts that require such a state.

  As shown in FIG. 1B, the wire clamp 10 has a wire position end 11 formed on one corner portion side, a bolt hole 12 formed on the wire position end 11, and a back side of the bolt hole 12. A wire step surface 13 is formed on which an adjuster bolt 1 (more precisely, a portion of a wire shaft 4 to be described later) around which the wire 20 is wound is located. The wire stepped surface 13 is preferably a space that allows the operator to confirm the wire 20 with the naked eye and put a finger.

  The adjuster bolt 1 includes a hexagonal head 2, a bolt shaft 3 connected to the head 2, and a wire shaft 4 extending from the bolt shaft 3, and a through-hole into which a wire 20 can be inserted into the wire shaft 4. 5 penetrates. Thereby, the wire shaft 4 can be wound by inserting the wire 20 into the through hole 5 and adjusting the wire 20 to the optimum tension.

  A screw is formed on the outer peripheral surface of the bolt shaft 3, and a screw is also formed on the inner peripheral surface of the bolt hole 12 at the wire position end 11 so that the bolt shaft can be inserted into the bolt hole and coupled with the screw.

  FIG. 2A shows a state where the adjuster bolt 1 is assembled to the wire clamp 10. The wire 20 is entangled with the adjuster bolt 1 to maintain the tension, and the adjuster bolt 1 is fastened to the wire clamp 10 by the bolt hole 12 at the wire position end 11.

  The fixing of this assembly is shown in FIG. 2 (B) and FIG. 2 (C). FIG. 2B shows a state in which the adjuster bolt 1 is inserted into the bolt hole 12 and the wire shaft 4 extending from the bolt shaft 3 of the adjuster bolt 1 is positioned on the wire step surface 13 side of the wire position end 11.

  In this state, the operator inserts the terminal portion of the wire 20 located on the wire step surface 13 into the through hole 5 formed in the wire shaft 4 and rotates the adjuster bolt 1.

  FIG. 2C shows a situation in which the operator rotates the adjuster bolt 1 so that the wire 20 is wound around the wire shaft 4 and tension is applied to the wire. In this way, when the operator feels that sufficient tension has been applied to the wire 20, the assembly is completed by applying a force (F) to the adjuster bolt 1 and pushing it in as shown in FIG.

  When force (F) is applied to the adjuster bolt 1, the end portion of the wire shaft 4 of the adjuster bolt 1 is fitted into a groove (or hole) formed in the wire position end 11 portion of the wire clamp 10 so that it cannot rotate. Fixed.

  In this way, the wire 20 is held by being wound around the wire shaft 4 while being sandwiched between the through holes 5, and the wire 20 is attached to the wire position end 11 of the wire clamp 10 as shown in FIG. It is assembled while maintaining a layout in which tension is formed along.

  In the wire tension adjuster of the present invention, the wire shaft 4 of the adjuster bolt 1 is provided with a through hole 5 so as to sandwich the wire 20, and the wire 20 is wound around the outer peripheral surface to give the wire tension, thereby adjusting the tension. . Therefore, the assembly work of the wire 20 is easily performed, and the tension of the wire can be arbitrarily set.

  Furthermore, when the wire 20 is assembled, it is possible to eliminate wire damage that may occur without the operator's knowledge, and it is possible to prevent the tension from being loosened and noise from being generated in the wire. The product value of the vehicle can be increased by eliminating claims.
