The present invention relates to a cable length adjustment mechanism.

  As an adjusting device for adjusting the attachment length of the control cable, one disclosed in Patent Document 1 is known (see FIGS. 9 to 12). An adjustment device for a control cable shown in Patent Document 1 includes an elongated end member (see reference numeral 101 in FIG. 9; hereinafter simply referred to as a rod 101) formed at an end of a control cable 100 whose length is adjusted; A holder 104 (see FIG. 11) in which the rod 101 is accommodated, and a lock piece that engages with the rod 101 in the holder 104 and restricts the movement of the rod 101 and the control cable 100 fixed to the rod 101 in the axial direction. 102 (refer to FIG. 10; a key in Patent Document 1) and a lock 103 (refer to FIG. 11) for fixing the lock piece 102. That is, the rod 101 fixed to one end of the control cable 100 is provided in the holder 104 shown in FIG. 11 so as to be movable in the axial direction (direction indicated by reference numeral D1 in FIG. 11), and the lock piece 102 is provided in the holder 104. In FIG. 11, an engaged portion 101 a (see FIG. 9) formed on the rod 101 and an engaging portion 102 a (see FIG. 9) formed on the lock piece 102 are inserted into the insertion hole 104 a provided on the rod 101 from above. 10) to adjust the position of the rod 101 in the axial direction. After engaging the engaged portion 101 a of the rod 101 and the engaging portion 102 a of the lock piece 102, the lock piece 102 is fixed to the holder 104 by sliding the lock 103 shown in FIG. 11 to the lock piece 102 side. Then, the adjustment of the length of the control cable 100 is completed.

  As shown in FIG. 10, the lock piece 102 used in this adjusting device has a substantially inverted U-shaped cross section, and an engaging portion 102a having grooves and protrusions alternately formed on the inner surface thereof. The lock piece 102 is provided over the entire length in the axial direction (the direction indicated by reference numeral D2 in FIG. 10). Although this engaging portion 102a is not described in Patent Document 1, the engaged portion 101a in which grooves and protrusions are alternately formed is engaged with the rod 101 provided on the outer surface, and then from the rod 101.

JP 2005-147393 A

  However, when such an engaging protrusion 102b is formed, when the mold is released from the lock piece 102 after the lock piece 102 is formed, the mold for forming the engaging portion 102a is impossible at the engaging protrusion 102b. Therefore, when the engagement protrusion 102b is provided at the end of the engagement portion 102a in the axial direction (the same direction as the direction indicated by reference numeral D2 in FIG. 10), the engagement portion 102a is caused by the stress caused by the forced removal. Is deformed outward (D2 direction in FIG. 10), and the lock piece 102 cannot be inserted into the insertion hole 104a of the holder 104, or the insertion resistance to the holder 104 increases, Insertion and removal may be difficult. That is, the end of the lock piece 102 in the axial direction D2 is deformed toward the outside (in the direction D2 in FIG. 10) by forcibly removing it, and when the lock piece 102 protrudes, the portion protruding outward causes the lock piece 102 to be inserted into the holder 104. When inserting into the attachment hole 104a, the lock piece 102 is caught by the inner wall 104b of the insertion hole 104a, and the lock piece 102 is difficult to insert. The problem that it becomes difficult to remove as a wedge arises.

  It is an object of the present invention to provide a lock piece that can be easily inserted into and removed from a holder without the vicinity of the engaging portion of the lock piece being deformed outward during molding.

  Hereinafter, referring to the accompanying drawings, the lock piece of the present invention, a control cable adjusting device having the lock piece (hereinafter simply referred to as an adjusting device), and a control cable length adjusting mechanism using the adjusting device (hereinafter simply referred to as long) Will be described in detail.

  As shown in FIGS. 1 to 3, the lock piece 1 of the present invention is disposed so as to be movable in the holder 2 in the axial direction (the direction indicated by reference numeral X in FIGS. A control cable attached to the rod 3 by fixing the position of the rod 3 in the axial direction X in the holder 2 by engaging with the rod 3 formed with the engaging portions 31 in which 31g and protrusions 31p are alternately arranged. This is for adjusting the length of 4. Moreover, the adjusting device 10 of the present invention includes the lock piece 1, and the length adjusting mechanism 10A of the present invention uses the adjusting device 10. The adjusting device 10 further includes a holder 2 and a rod 3, and is long. After the lock piece 1 is attached to the holder 2, the height adjusting mechanism 10 </ b> A is attached to the slider 3 and the rod 3 to be engaged with the lock piece 1 in order to check whether the lock piece 1 is securely attached to the holder 2. A control cable 4 having one end fixed is further provided.

  As shown in FIG. 2, the holder 2 to which the lock piece 1 is attached is provided with a fitting hole 21 at one end (the right end of the holder 2 in FIG. 2, hereinafter referred to as the front end). For example, a pin or the like (not shown) provided on the shift lever is fitted into the fitting hole 21 and attached. Further, the other end of the holder 2 (the left end of the holder 2 in FIG. 2, hereinafter referred to as a base end) is provided with an insertion hole 22 a for inserting the rod 3. Further, a slider 5 for confirming whether or not the lock piece 1 is securely attached to the holder 2 is provided at the base end of the holder 2, and the slider 5 is moved from the base end side to the tip end side of the holder 2. By sliding, it engages with an engaging claw 14 provided on the lock piece 1.

  As shown in FIG. 2, the holder 2 is formed with a cavity 23 having a substantially rectangular cross section that is guided by being inserted from above in FIG. 2. The cavity 23 is formed to have substantially the same dimensions as the outer shape of the lock piece 1 in order to guide the lock piece 1 (see FIG. 1). Therefore, when the lock piece 1 is inserted into the cavity 23, only a slight clearance is formed between the inner wall 24 (see FIG. 2) of the holder 2 in which the cavity 23 is formed and the lock piece 1. Therefore, the lock piece 1 is stably guided while sliding in the cavity 23.

  As shown in FIGS. 1 and 2, the rod 3 is inserted into the holder 2 from the insertion hole 22a. The insertion hole 22 a communicates with the cavity 23 from the outside of the base end of the holder 2, and an insertion hole 22 b is further formed from the cavity 23 toward the holder distal end side. The rod 3 is inserted into the insertion holes 22a and 22b, and is arranged so as to be movable along the axial direction X in the holder 2, that is, in the insertion holes 22a and 22b and the cavity 23. As shown in FIG. 3A, the control cable 4 is inserted into one end of the rod 3 (the left end of the rod 3 in FIGS. 2 and 3A, hereinafter referred to as the rod base end). An insertion portion 32 is formed, and the control cable 4 is inserted into the insertion portion 32 on the rod proximal end side and fixed by caulking or the like. The other end of the rod 3 (the right end of the rod 3 in FIGS. 2 and 3A, hereinafter referred to as the rod tip) side is along the axial direction X as shown in FIGS. 3A and 3B. Thus, an engaging portion 31 is formed in which grooves 31g and protrusions 31p are alternately formed. The engaging portion 31 may be formed integrally with the groove 31g and the protrusion 31p on the rod 3 itself, or may be formed by providing another member on the rod tip side as shown in FIG. Good. Further, in FIG. 2 and FIG. 3A, the groove 31g and the protrusion 31p are formed annularly in the circumferential direction of the rod 3, respectively, but the groove 31g and the protrusion 31p are partially in the circumferential direction of the rod 3. May be formed. That is, it is only necessary that the engaging portion 31 that can be engaged with the lock piece 1 is provided by the groove 31g and the protrusion 31p of the rod 3. Further, the shape of the rod 3 is also circular in FIG. 2 and FIG. 3A, but if the rod 3 has a groove 31g and a projection 31p that can be engaged with the lock piece 1, the shape of the rod is rectangular. Needless to say, it may have a polygonal cross section.

  In order to adjust the position of the rod 3 in the axial direction X in the holder 2 and thereby adjust the length of the control cable 4 attached to the rod 3, the rod 3 is operated in the axial direction X in the holder 2 After the position adjustment, the engaged portion 11 (see FIG. 4B) formed on the lock piece 1 described later is engaged with the engaging portion 31 of the rod 3. Hereinafter, the lock piece 1 will be described.

  As shown in FIG. 2 and FIG. 4A, the lock piece 1 has a substantially cross-sectional shape including a pair of side walls 12a and 12b facing each other and a connecting wall 13 spanning the pair of side walls 12a and 12b. It is formed so as to have an inverted U shape. When the lock piece 1 is inserted into the cavity 23 of the holder 2, the side walls 12 a and 12 b are located between the inner wall 24 of the holder 2 in which at least a part or all of the outer periphery of the side walls 12 a and 12 b is provided with the cavity 23. The outer dimensions are such that there is almost no clearance. Therefore, the lock piece 1 is guided in the cavity 23, and the engagement between the engaging portion 31 of the rod 3 and the engaged portion 11 of the lock piece 1 becomes smooth. Note that the substantially U-shaped cross-section means a structure in which the lower part of the lock piece 1 is opened in order to engage the lock piece 1 with the rod 3, and is strictly U-shaped. There is no need.

  2, 4 (a) and 4 (b), the shape of the lock piece 1 is formed by hollowing out a substantially rectangular parallelepiped member as a whole to form a kamaboko-shaped space, and the shape of the cavity 23 of the holder 2. Is shown as a substantially rectangular cross-section. However, the shape of the lock piece 1 is not limited to the outer shape shown in FIGS. 2, 4 (a) and 4 (b), and is not particularly limited as long as it can be guided in the cavity 23. . Similarly, the outer shape of the cavity 23 is not particularly limited as long as it can accommodate and guide the lock piece 1 with almost no gap.

  The lock piece 1 is preferably made of a synthetic resin from the viewpoint of ease of processing and the like, but can also be made of metal such as aluminum, aluminum alloy, zinc, zinc alloy, and the material is particularly limited. Is not to be done. Further, the method of forming the lock piece 1 is not particularly limited, but when the lock piece 1 is made of synthetic resin, it can be formed by injection molding, such as aluminum, aluminum alloy, zinc, zinc alloy, etc. In the case of metal, it can be cast by die casting.

  As shown in FIGS. 4B and 4C, the pair of side walls 12 a and 12 b of the lock piece 1 and the inner surface side of the connecting wall 13 (the side indicated by reference numeral IS in FIG. 4A) Over the entire length in the axial direction (the same direction as the axial direction X of the rod 3 when the lock piece 1 is attached to the holder 2; hereinafter simply referred to as the axial direction X) so as to engage with the engaging portion 31 of Engaged portions 11 in which grooves 11g and protrusions 11p (see FIG. 4C) are alternately arranged are formed. The groove 11g of the engaged portion 11 engages with the protrusion 31p of the engaging portion 31, and the protrusion 11p of the engaged portion 11 engages with the groove 31g of the engaging portion 31 to lock the rod 3 The piece 1 is engaged and fixed.

  As shown in FIGS. 4 (b), 4 (c) and 5 (a), the engaged portion 11 is directed from one inner surface side IS of the side walls 12a, 12b toward the other side wall 12a, 12b. A protruding engagement protrusion P is formed by removing the end portion 11 e in the axial direction X of the engaged portion 11. As shown in FIGS. 4B, 4C and 5A, the engaging protrusion P protrudes from the inner surface IS of the side wall 12a toward the other side wall 12b. An engaging protrusion P protrudes from the inner surface IS of the side wall 12b toward the other side wall 12a. In addition, although the engagement protrusion P is provided in the part of the groove | channel 11g of the to-be-engaged part 11 of the lock piece 1 in FIG.4 (b), (c) and FIG.5 (a), The engaging protrusion P may be provided on the protrusion 11p of the joint part 11. 4 (b), (c) and FIG. 5 (a), the engaging protrusions P are formed on both of the side walls 12a and 12b, but only on one of the side walls 12a and 12b. A confronting protrusion P may be formed.

  The position at which the engagement protrusion P is provided (the position in the vertical direction in FIGS. 6A and 6B) is not particularly limited, but in order to make it difficult for the lock piece 1 to come off, the lock piece 1 is a rod. 3 (a state shown in FIG. 6 (b)), slightly below the position where the rod 3 is horizontally cut along the axial direction X (the central portion in the vertical direction of the rod 3 in FIG. 6 (b)). It is preferable to project from the slightly lower side) along the outer periphery of the engaging portion 31 of the rod 3.

  As shown in FIGS. 6 (a) and 6 (b), the engagement protrusion P protrudes toward the opposite side walls 12a and 12b, and locks from above the rod 3 arranged in the holder 2. When the piece 1 is inserted into the cavity 23, the engagement protrusion P can be engaged with the outer periphery of the engagement portion 31 of the rod 3, and the lock piece 1 can be prevented from being detached from the rod 3. Furthermore, as shown in FIGS. 4B and 4C, the engagement protrusion P of the present invention is formed by removing the end 11e in the axial direction X of the engaged portion 11 as shown in FIGS. Has been. Here, “formed by removing the end portion 11e in the axial direction X of the engaged portion 11” means that the end portion 11e in the axial direction X shown in FIG. 4B is removed (in addition to the end portion 11e). That is, it is only necessary that the mating protrusion P is formed. 4 (b), 5 (a), and 5 (b), the lock piece 1 has four engaging protrusions P by removing both end portions 11e, 11e of the engaged portion 11 of the side walls 12a, 12b. The engagement protrusion P is not formed in the central portion of the lock piece 1 in the axial direction X, but the engagement protrusion P is formed in each groove 11g of the engaged portion 11 or each protrusion 11p. May be provided, or the engagement protrusion P may be provided only in the central portion of the lock piece 1 in the axial direction X. The “end portion 11e in the axial direction X of the engaged portion 11” refers to the protrusion 11p at the end of the engaged portion 11 in which the protrusions 11p and the grooves 11g are alternately arranged. When the engaging protrusion P is provided on 11g, the engaging protrusion P is provided in the groove 11g provided on the center side in the axial direction X of the lock piece 1 adjacent to the protrusion 11p at the end. Further, when the engagement protrusion P is provided on the protrusion 11p, the engagement protrusion P is provided on the protrusion 11p that is adjacent to the protrusion 11p at the end and provided on the center side in the axial direction X of the lock piece 1. .

  In this manner, by forming the engaging protrusion P by removing the end 11e in the axial direction X of the engaged portion 11, the stress generated by forcibly removing the mold after the lock piece 1 is formed is prevented. Since it is absorbed around the portion P, the vicinity of the engaged portion 11 does not deform outward when the lock piece 1 is molded. That is, when the engagement protrusion P is formed at the end portion 11e in the axial direction X of the engaged portion 11 when the lock piece 1 is molded, the side wall 12a of the lock piece 1 due to the stress generated by forcibly removing the mold, 12b will deform | transform so that it may protrude toward the outer side (X direction side in FIG. 2). When the side walls 12a and 12b are deformed outward, the lock piece 1 has an outer dimension with only a small clearance from the inner wall 24 of the holder 2 where the cavity 23 is provided. 23, it becomes difficult to insert the lock piece 1 from the cavity 23 of the holder 2, and it becomes difficult to remove the lock piece 1 from the cavity 23 of the holder 2. Therefore, by forming the engagement protrusion P by removing the end 11e in the axial direction X of the engaged portion 11, deformation at the time of molding of the lock piece 1 can be prevented. Removal is easy. Furthermore, the lock piece 1 can be attached to and detached from the cavity 23 of the holder 2 with a stable low operating force with little variation and a moderate feeling of moderation.

  Further, when the lock piece 1 is made of synthetic resin, the lock piece 1 becomes hard when the temperature is low, such as in winter, and the lock piece 1 itself is not easily deformed when the lock piece 1 is inserted or removed. In an environment with high humidity such as time, the lock piece 1 expands, and the clearance between the lock piece 1 and the cavity 23 becomes small. Due to the outward deformation at the time of molding, the lock piece 1 enters the cavity 23. There is a problem that insertion and removal become more difficult. However, in the lock piece 1 of the present invention, since the engagement protrusion P is formed by removing the end portion 11e in the axial direction X of the engaged portion 11, it is possible to prevent deformation of the lock piece 1 during molding. Therefore, even when there is such a change in environment such as temperature change and humidity, the lock piece 1 can be inserted into and removed from the cavity 23 of the holder 2 with a low operating force.

  Moreover, since the adjusting device 10 of the control cable 4 provided with the lock piece 1 can be easily inserted into and removed from the holder 2, the position adjustment of the rod 3 for adjusting the length of the control cable 4 is possible. And fixing work becomes easy.

  Further, the length adjusting mechanism 10A of the control cable 4 using the adjusting device 10 can be easily inserted into and removed from the holder 2 of the lock piece 1, and the position of the rod 3 for adjusting the length of the control cable 4 Since adjustment and fixing work are facilitated, the length of the control cable 4 can be easily adjusted.

  Below, an example of the manufacturing method of the lock piece 1 of this invention is demonstrated.

  As shown schematically in FIG. 7, the lock piece 1 is roughly molded from three molds M1, M2, M3. Outer shapes such as the side walls 12a and 12b and the connecting wall 13 of the lock piece 1 are molded by the molds M1 and M2, and the engaged portion 11 on the inner surface IS of the lock piece 1 is molded by the mold M3. In order to form the engaged portion 11 of the lock piece 1, the mold M <b> 3 protrudes in a semi-cylindrical shape, and the curved portion C that is a portion protruding in the semi-cylindrical shape forms the engaged portion 11. As shown in FIG. 7, a plurality of grooves and protrusions are alternately formed. In the bending portion C of the mold M3, a concave portion corresponding to the shape of the engaging protrusion P is formed in either the groove or the protrusion of the bending portion C in order to form the engaging protrusion P of the engaged portion 11. It is formed. Since the mold M3 is formed by removing the end 11e in the axial direction X of the engaged portion 11 of the lock piece 1 from the mold M3, the concave portion corresponding to the shape of the engaging projection P is a curved portion. It is formed by removing the end portion ME of C.

  First, from the state where the molds M1, M2, and M3 shown in FIG. 7 are opened, as shown in FIG. 8A, the three molds M1, M2, and M3 are closed. After the molds M1, M2, and M3 are closed, the molten resin is injected into the space S corresponding to the shape of the lock piece 1 that is formed by closing the molds M1, M2, and M3 by a nozzle of an injection unit (not shown). Is done. When the resin in the space S is cooled, the injection unit moves backward, and then the molds M1, M2, and M3 are released from the lock piece 1 that is a molded product. As shown in FIG. 8 (b), the mold M1 is first released from the lock piece 1 as a molded product, and then the mold M3 is lowered and released from the lock piece 1 as shown in FIG. 8 (c). .

  At this time, an engagement protrusion P is formed on the inner surface IS of the lock piece 1 which is a molded product, and the inner surface IS of the lock piece 1 is formed to form the engagement protrusion P also on the mold M3. Because of the corresponding shape, when the mold M3 is released, it is impossible to force between the curved portion C of the mold M3 and the engagement protrusion P of the lock piece 1. When the engagement protrusion P is provided at the end 11e of the engaged portion 11 of the lock piece 1, the resin constituting the lock piece 1 is still soft when the mold M3 is released, so the mold M3 is released. Of the surface having a substantially U-shape formed by the pair of side walls 12a and 12b and the connecting wall 13 of the lock piece 1 due to the stress caused by unreasonable pulling, the portion where the mold M1 is released is shown in FIG. In (c), the sheet is deformed (protruded) toward the front side and the depth direction. This is because the stress applied to the engagement protrusion P tends to escape to a thin portion adjacent to the engagement protrusion P. When the lock piece 1 is inserted into the cavity 23 of the holder 2, Further, due to deformation (protrusion) in the substantially U-shaped surface caused by unreasonable removal, it becomes difficult to insert into the cavity 23, and after insertion into the cavity 23, the part protruding by deformation becomes a wedge, This makes it difficult to remove the lock piece 1 from the cavity 23 by abutting against the inner wall 24 of the holder 2. Further, in FIG. 8C, the part in the mold M2 after the mold M3 is released is also deformed after the mold M2 is released due to internal stress caused by forced removal.

  However, in the present invention, the engaging projection P is formed by removing the end portion 11e in the axial direction X of the engaged portion 11, so that the thickness of the portion adjacent to the engaging projection P is increased. The stress generated when the mold M3 is released from the lock piece 1 that is a molded product is dispersed and absorbed inside the molded product, and the stress does not reach the surface of the lock piece 1 that is substantially U-shaped. Therefore, there is no deformation in the surface where the lock piece 1 faces the cavity 23 of the holder 2. Therefore, the lock piece 1 can be easily inserted into and removed from the holder 2.

  In addition, the said manufacturing method is an example to the last, and the engagement protrusion P can be formed in the to-be-engaged part 11 of the lock piece 1 by removing the edge part 11e of the to-be-engaged part 11 in the axial direction X. Then, the shape of the mold, the number of molds, the order of mold release, timing, etc. are not limited to the above method.
