Description

  The present invention relates to a locking device, and more particularly to a device for locking a member that can move along a long member having a thread at a predetermined position of the long member.

  Generally, when fixing another member at a predetermined position of the long member, a binding wire or the like is often used to bind the long member and the other member. However, when the object to be fixed is large and it is not easy to bind, or when the position to be fixed is narrow and cannot be bound by the binding wire, such a fixing method cannot be used. Therefore, in such a case, there is a method in which an object to be attached is divided into two parts and is clamped with bolts and nuts so as to be sandwiched from both sides of the long member (see Patent Documents 1 and 2). ). In order not to easily change these locking positions, a thread is provided on the surface of the long member, and a thread groove is formed in the contact portion so that the locking state is maintained by the engagement between the two. Was configured.

  Among the prior arts, the one disclosed in Patent Document 1 uses one of the divided objects already fixed to a predetermined place and the other divided while a long member is in contact with the one. The long member is sandwiched (see FIG. 3 of Patent Document 1). Moreover, what is disclosed by patent document 2 is for fixing the elongate object arrange | positioned with respect to a elongate member in the orthogonal direction (refer FIG. 2 of patent document), A plurality of contact portions are provided in parallel in the longitudinal direction (see FIGS. 3 and 4).

  However, when the object to be locked to the long member is not a structure that can be detached from the long member (joined parts are combined) as in the prior art, the locking device is used. Sometimes it was unsuitable to use. That is, when the locking position is adjusted while moving (sliding) in the axial direction of the long member, and the locking position is adjusted at the position after the adjustment, the locking device can be easily removed from the long member. It was adjustable. In addition, after adjusting the locking position with only one of the divided parts, the adjustment position is changed by fastening with bolts and nuts when integrating with the other divided part. Such misalignment of the adjustment position at the time of fastening with a bolt or the like may occur even with a locking device that is not divided.

  The present invention has been made in view of the above-mentioned points. The object of the present invention is to enable locking immediately after adjusting the locking position while moving along the long member, and using bolts or the like. To provide a locking device that does not require fastening.

  Accordingly, the present invention provides a locking device that locks a slider that is movable in the axial direction of a long member having a thread on the long member. A slider body that is movable along the axis of the scale member, and a pressing member that is rotatably provided on the slider body and sandwiches and holds the elongated member together with the slider body. An insertion hole that allows the long member to pass therethrough and a sliding contact portion that slides on the surface of the long member, and the pressing member forms a screw groove that engages with a thread of the long member. A screw groove forming portion and a hook portion that hooks the slider main body in a state in which the screw groove forming portion is pressed against the surface of the long member.

  According to the above configuration, by inserting the elongated member into the insertion hole provided in the slider body, the slider body can move along the longitudinal direction of the elongated member, and an appropriate position where the slider should be locked is set. It becomes easy to adjust on the long member. Further, after adjusting the locking position, the long member can be held between the sliding contact portion of the slider body and the thread groove forming portion of the pressing member by pressing the long member with the pressing member. Since the screw groove provided in the screw groove forming portion of the pressing member is engaged with the screw thread of the long member by the clamping at this time, the slider is prevented from sliding in the longitudinal direction of the long member. It is possible to lock. Furthermore, since the latching part is provided in the pressing member, the latching state is maintained by latching the latching part on the slider body in the above-described pressing state (locking state). It can be done.

  According to the present invention, in the above configuration, the slidable contact portion of the slider main body can be a slidable contact portion formed by a semicylindrical smooth internal surface having an appropriate length in the generatrix direction.

  With the above configuration, when the long member is not clamped by the pressing member, only the inner surface of the insertion hole and the sliding contact portion come into contact with the surface of the long member. Therefore, the slider can be moved (slid) along the long member without being caught by the slider. In addition, in the semi-cylindrical bus direction, the appropriate length is preferably at least one pitch of the thread provided on the long member. The insertion hole is preferably a round hole and the inner surface is preferably a smooth surface. Further, when the slider is moved (sliding), the pressing member is rotated so that the thread groove forming portion is long. It is preferable that the surface is not in contact with the surface of the scale member.

  Further, according to the present invention, in the above configuration, the insertion hole of the slider body has an inner surface continuous to the sliding contact portion and is formed with the same inner diameter as the semicylindrical shape forming the sliding contact portion. An insertion hole having a smooth inner surface can be provided.

  With the above configuration, the long member can move (slide) the slider while being inserted into the insertion hole. In this state, both the inner surface of the insertion hole and the surface of the sliding contact portion slide on the surface of the long member. You will be in touch. Since each of these surfaces is smooth, by setting the thread groove forming portion of the pressing member away from the long member, the thread of the long member is not caught on the slider, and the slider is It can be moved (slided) along the long member.

  Furthermore, the present invention is such that, in the above configuration, the pressing member includes a shaft portion mounted on the slider body, and the slider body includes support means for pivotally supporting the shaft portion. It is good also as a structure provided.

  According to the above configuration, the pressing member can be pivotally supported by the slider body, and the slider body and the pressing member can be supported by supporting the shaft portion of the pressing member by the support means of the slider body. Can be integrated. The center of rotation of the pressing member is the axis of the shaft, and the position of the axis is fixed by the support means of the slider body, so that the pressing member can rotate around the same position. Therefore, the thread groove forming portion of the pressing member can abut on the surface of the long member at a predetermined position of the slider body.

  Further, the present invention is a locking device that locks a slider that is movable in the axial direction of a long member having a screw thread to the long member. A slider body that is movable along the axis of the scale member, and a pressing member that is rotatably provided on the slider body and sandwiches and holds the elongated member together with the slider body. At least two plate-like members arranged in parallel at an appropriate interval, an insertion hole for allowing all of the plate-like members to penetrate in a straight line and allowing the long member to be inserted, and maintaining the appropriate interval A connecting member for connecting the plate-like members, and a semi-cylindrical inner surface having the same diameter as the inner diameter of the insertion hole while being continuous with the inner surface of the insertion hole on one surface of the connection member, A sliding contact portion that is in sliding contact with the surface of the long member, The pressing member includes a main body portion disposed between the plate-like members, a shaft portion pivotally supported by the plate-like member, and a thread groove that engages with a thread of the long member. The screw groove forming portion is formed, and a latch portion that restricts the rotation in a state where the screw groove forming portion is pressed against the surface of the long member.

  According to the above configuration, since at least two plate-like members constituting the slider body are provided with insertion holes, respectively, by inserting the long member into all of these insertion holes, the slider body Only the movement (sliding) of the long member in the axial direction and the rotation around the axis (circumferential direction) are free. As a result, even when the slider is moved along the axial direction of the long member (position adjustment), the surface of the long member always comes into sliding contact with the sliding contact portion, and is pressed by the pressing member. Locking in the same state is possible.

  According to the present invention, in the above-described configuration, the latching portion of the pressing member has a latching claw at the tip and protrudes from the free end of the pressing member, and the slider body is located near the tip of the latching portion. A configuration may be provided that includes a hooked portion that allows insertion and receives the hook of the hooking claw.

  According to the said structure, the state which pressed the elongate member surface by the press member can be maintained, and the latching state of a slider can be stabilized. That is, as long as the latching claw is in a state of being latched by being configured so that the latching claw is latched to the latched portion when the pressing force necessary for locking is applied to the pressing member. Since the pressing force necessary for locking the slider is always maintained, the pressing force can be continuously applied. In addition, since the thread groove forming portion is formed on the pressing member, there is a protruding portion similar to the thread on the boundary of each groove of the thread groove forming portion. When abutting against the thread, a state where the pressing member is not sufficiently locked is assumed. In this case, in order to determine whether or not the thread groove of the thread groove forming portion is actually engaged with the thread of the long member, the determination may be made based on whether or not the latching claw can be engaged. . That is, when the thread of the long member and the protruding portion of the thread groove latching portion come into contact with each other, the protruding portions are in contact with each other, so that the pressing member cannot be sufficiently rotated. In such a state, if the protrusion length from the free end of the pressing member is adjusted so that the hooking claw does not reach the hooked portion, if the hook cannot be hooked, the screw groove of the screw groove forming portion is long. It can be determined that the member is not engaged with the thread of the member.

  Further, according to the present invention, in the above-described configuration, the pressing member is protruded toward the surface of the plate-like member located on both sides where the pressing member is arranged, and slides on the surface of the plate-like member when rotating around the shaft portion. It is good also as a structure provided with the projection part which touches.

  In the case of the above configuration, smooth rotation of the pressing member can be restricted, and the pressing member is inadvertently rotated in the positioning step on the long member (the step of moving (sliding) the slider). It can avoid moving and a thread groove formation part engaging with an elongate member. In addition, for example, in the case where a protrusion receiving hole into which the protrusion can be inserted is provided on the plate-like member side of the slider body, the posture of the pressing member relative to the slider body can be positioned. The positioning of the relative posture of both is not only when the slider is in a state of locking the long member, but also when it is in a desired rotating state when the long member is moved (sliding) in the axial direction However, when both need to be positioned, two protrusions and two protrusion receiving holes may be provided.

  According to the present invention, by inserting the elongated member into the through hole of the slider body, the slider body can move along the longitudinal direction without detaching from the elongated member, and by rotating the pressing member, Since the thread groove forming portion of the pressing member can be engaged with the thread of the long member, it can be locked immediately after adjusting the position of the slider on the long member. Moreover, since the pressing member can be latched in the state pressed with respect to the elongate member, it can maintain the said latching state.

  In addition, since the slider body is provided with a sliding contact portion, and the sliding contact portion is formed of a smooth surface, the slider body is a long member when the pressing member does not press the long member. Therefore, it is easy to freely slide the slider body along the longitudinal direction of the long member.

  Further, when the sliding contact portion is semi-cylindrical and the inner surface of the insertion hole and the sliding contact portion are continuous, the inner surface of the insertion hole can be slidably contacted with the surface of the long member together with the sliding contact portion. Therefore, the slider main body can be stably slidably contacted on the long member.

  In addition, since the latching | locking part of a press member is a structure latched on a slider main body, in the state which the said latching | hanging part latches on a slider main body, a slider is integrated and the whole slider is on a long member. It will be installed at one point. Then, by releasing the latching portion from the slider main body, the slider can be easily detached from the long member (released from the locked state).

As shown in these drawings, in the present embodiment, the slider SL composed of the slider body 1 and the pressing member 2 moves along the longitudinal direction of the long member BP having the thread MS on the surface. The long member BP can be locked at an appropriate position of the long member BP. The locking device is formed by the slider main body 1 and the pressing member 2 constituting the slider SL while utilizing the thread MS of the long member BP.

  Then, each structural member which forms a locking device is demonstrated. As shown in FIG. 1, the slider body 1 is provided with insertion holes 11 and 12 through which the long member BP can be inserted, and between the two insertion holes 11 and 12, the surface of the long member BP. A sliding contact portion 13 having a semicircular cross section is provided. Further, the slider body 1 has support means 3 and 4 for rotatably supporting the pressing member 2, and the supporting means 3 and 4 support the base end portion (shaft portion) 21 of the pressing member. , 22 as shown in FIG. 2, both the members 1 and 2 can be configured integrally while rotatably supporting the pressing member 2.

  The pressing member 2 is a member that rotates around the base end portions (shaft portions) 21 and 22, and is supported by the support means 3 and 4 of the slider body 1, so that the center of the rotation is In the vicinity of one end of the slider body 1 on which the support means 3 and 4 are provided. Therefore, the rotation about the base end portions (shaft portions) 21 and 22 brings the other end (free end) 23 closer to the slider body 1 when rotating in one direction (FIG. 2B). )), When rotating in the opposite direction, the other end (free end) 23 is separated from the slider body 1 (see FIG. 2A).

  In the present embodiment, when the pressing member 2 brings the other end (free end) 23 closer to the slider body 1 with the base end portions (shaft portions) 21 and 22 as the center, the slider body 1 and the pressing member 2 are in contact with each other. It is comprised so that the elongate member BP can be pinched | interposed. That is, the portion where the pressing member 2 abuts on the long member BP has a hook shape that matches the outer shape of the long member BP, and a thread groove forming portion 24 in which the thread groove FS is formed on the surface thereof is provided. When contacting the scale member BP, the thread groove FS of the thread groove forming portion 24 is configured to engage with the thread MS of the long member BP. Therefore, when the long member BP is sandwiched between the slider main body 1 and the pressing member 2, the slider main body 1 side is in sliding contact with the surface of the long member BP, and the pressing member 2 side is The thread groove forming portion 24 is engaged with the surface of the long member BP.

  Further, the free end 23 of the pressing member 2 is provided with a latching portion 25, and the latching portion 25 latches the slider body 1 so that the pressing member 2 is pressed (the thread MS and the screw). The engagement state with the groove FS) can be maintained. The latch body 25 can be latched to the slider body 1 by hooking a part of the latch section 25 to any part of the slider body 1. In the embodiment, a claw-like latching head portion 26 is provided near the tip of the latching portion 25, while an engagement hole 14 is provided in the slider body 1. And when the latching | locking part 25 penetrates this engaging hole 14, it is comprised so that the slider main body 1 can be latched by the latching head 26. FIG.

  Here, details of both members 1 and 2 forming the locking device will be further described. As shown in FIG. 1, the entire slider body 1 is composed of two plate-like members 5 and 6 and a connecting member 7 that connects both members 5 and 6. The plate-like members 5 and 6 are formed in a substantially rectangular shape in plan view, and these plate-like members 5 and 6 are arranged with an appropriate interval by the connecting member 7, and the appropriate interval is determined by the pressing member 2. It is provided to the extent that can be stored. Further, on the substantially rectangular surface of the plate-like members 5 and 6, two kinds of ribs 51, 52, 61 and 62 respectively extending in the vertical and horizontal directions are provided with appropriate dimensions in the width direction. The strength with respect to the bending direction 6 is improved.

  The above-described insertion holes 11 and 12 are provided at substantially the center of the plate-like members 5 and 6, respectively, and both the insertion holes 11 and 12 are provided to penetrate the plate-like members 5 and 6 so as to be in a straight line. Has been. By providing the insertion holes 11 and 12 in the two plate-like members 5 and 6 having an appropriate interval, the long member BP that is simultaneously inserted into the both 11 and 12 is supported at two points apart. The slider body 1 can be moved while maintaining the same posture along the axial direction of the long member BP. Further, circular ribs 53 and 63 having appropriate dimensions in the width direction are provided around the insertion holes 11 and 12 similarly to the ribs 51, 52, 61 and 62, and the insertion holes 11 and 12 are just the circular ribs 53. , 63 is provided in the center. By providing the circular ribs 53 and 63, the strength of the inner peripheral edge of the insertion holes 11 and 12 can be improved, and a wall surface having a predetermined area can be formed inside the insertion holes 11 and 12. The inner wall surface of the predetermined area can be slidably contacted with the surface of the long member BP with an appropriate length, and can slide along the surface of the long member BP together with the sliding contact portion 13. Yes.

  FIG. 3A is a view showing a cross section at an intermediate position between the two plate-like members 5 and 6 of the slider body 1. As shown in this figure, the connecting member 7 does not connect the entire surfaces of the plate-like members 5 and 6, but on one side (rear side (upper side in the figure)) with the approximate center of the insertion holes 11 and 12 as a boundary. It connects only in the range (this is called the connection area | region 71). Thus, by providing the connection member 7 only in the connection region 71, a semi-cylindrical shape having the same diameter along a straight center line where the insertion holes 11 and 12 are provided is part of the connection member 7. By forming the surface, the surface of the semi-cylindrical portion is configured as the sliding contact portion 13. Further, a range where the connecting member 7 is not provided (referred to as an open area 72) is formed on the other side (surface side (lower side in the drawing)) of the slider body 1, and the range of the open area 72 By configuring the pressing member 2 with a size and shape that can be accommodated therein, the pressing member 2 can be housed inside the slider body 1 (open region 72) in the locked state.

  Further, the connecting member 7 is provided with a part that is not partially connected to the short side of the substantially rectangular shape formed by the plate-like members 5 and 6 in the connecting region 71, and the base end of the pressing member 2 is provided in this part. Support means 3 and 4 for supporting the portions (shaft portions) 21 and 22 can be formed (see FIG. 1). Specifically, as shown in FIG. 3A, the support means 4 has a cutout portion 41 in which a part of the plate-like member 6 is cut out in a semicircular shape, and protrudes toward the cutout portion 41. The two projecting pieces 42 and 43 are configured. The tips of the two projecting pieces 42 and 43 are configured to reach a circumferential edge when a virtual circle is formed by an extension line of a semicircle formed by the notch 41, and the virtual circle is The pressing member 2 has the same diameter as the outer circumference of one shaft portion 22 of the pressing member 2.

  That is, the notch portion 41 and the two projecting pieces 42 and 43 are in sliding contact with the outer peripheral edge of the shaft portion 22, thereby supporting the shaft portion 22 in a freely rotatable manner. In addition, the projecting pieces 42 and 43 extend toward the center of the virtual circle from the both ends of the notch 41 and are provided so as to gradually approach the tips of the projecting pieces 42 and 43. Therefore, by causing the shaft portion 22 of the pressing member 2 to enter between the two projecting pieces 42 and 43, the projecting pieces 42 and 43 allow the shaft portion 22 to pass through while gradually increasing the distance between the tips. When 22 abuts on the notch 41, the tips of the projecting pieces 42 and 43 are restored so that the detachment of the shaft 22 can be restricted.

  Thus, the state which supported the axial part 22 with the notch part 41 and the protrusions 42 and 43 is shown in FIG.3 (b). As shown in this figure, the supported shaft portion 22 can be rotated while being in sliding contact with the notches 41 and the tips of the projecting pieces 42 and 43 at the position. The entire pressing member 2 is mounted on the slider main body 1 in a rotatable state. 3A shows only one support means 4, and FIG. 3B shows only the state in which one shaft portion 22 is supported by the support means 4. The other support means 3 has the same configuration, and the other shaft portion 21 supported by the support means 3 is also rotatably supported.

  Further, as shown in FIGS. 3A and 3B, the connecting member 7 has a thickness (front-rear direction (in the drawing) on the side of the connecting region 71 where the support means 3 and 4 are not formed. A portion in which (thickness dimension in the vertical direction) is thinned is provided (this portion is referred to as a hooked portion 73). The hooked portion 73 is provided with an engaging hole 14 that partially penetrates the connecting member 7. The engagement hole 14 is provided with a size that allows the latching portion 25 of the pressing member 2 to be inserted. The rear surface side (upper surface side in the drawing) of the latching portion 73 is provided around the engagement hole 14. The engaging recess 15 is formed by cutting out a part. The engaging recess 15 is provided on the engaging head 26 when the tip of the pressing member 2 (the engaging head 26) reaches the back side of the engaged portion 73 beyond the engaging hole 14. The stop protrusion 27 is provided so that it can be engaged.

  FIG. 3C shows a state in which the latching protrusion 27 is engaged with the engaging recess 15. As shown in this figure, when the latching head 26 provided in the latching part 25 passes through the engaging hole 14, the latching head 26 of the latching part 25 moves the back side of the latched part 73. In addition, the latching protrusion 27 is engaged with the engagement recess 15 so that the engagement state cannot be easily released.

  In this embodiment, the engaging hole 14 is provided in the connecting member 7 so that the engaging portion 25 of the pressing member 2 can be inserted. However, the engaging head 26 can be engaged with the connecting member 7. If so, it is not necessary to provide the engaging hole 14 through which the latching portion 25 is inserted. That is, in this embodiment, in addition to the connecting member 7 that connects the two plate-like members 5 and 6, a common rib 8 that connects the two plate-like members 5 and 6 is formed in the vicinity of the insertion hole 14. (See FIGS. 1 and 3), the engaging hole 14 is inserted to reach the latch head 26 to the back side of the connecting member 7, but the common rib 8 is not provided. In the case of the configuration, it is possible to reach the back side through the side portion of the connecting member 7.

  Next, the configuration of the pressing member 2 will be described in detail. As shown in FIGS. 1 and 2, the main body portion 20 of the pressing member 2 has a substantially rectangular parallelepiped shape, with the one end 20 a in the longitudinal direction as a base end on the connection side with the slider main body 1, The distal end side 20 b is a free end 23. As described above, the shaft portions 21 and 22 to be supported by the support means of the slider main body 1 protrude from the upper surface portion 20c and the lower surface portion 20d of the main body portion 20 in the vertical direction on the base end side 20a. It is provided to do. The centers of the shaft portions 21 and 22 are set at positions along the plane portion of the main body portion 20 that contacts the connecting member 7 of the slider main body 1 (referred to as a contact side wall surface portion 20e). When the pressing member 2 rotates about the axis, the abutting side wall surface portion 20e is provided so as to rotate around the axis.

  Further, the abutting side wall surface portion 20e of the main body portion 20 of the pressing member 2 is provided with a thread groove forming portion 24 that is cut into a semi-cylindrical shape having a generating line in the vertical direction, and a thread groove is formed on the notched surface. It has been. The thread groove forming portion 24 can form a substantially cylindrical space together with the sliding contact portion 13 of the slider main body 1 when the abutting side wall surface portion 20 e contacts the connecting member 7 of the slider main body 1. Moreover, the thread groove provided in the thread groove forming part 24 is formed at the same pitch as the thread so as to engage with the thread on the surface of the long member BP to be locked.

  On the other end side 20 b (free end 23) of the main body portion 20 of the pressing member 2, a latching portion 25 that protrudes in the orthogonal direction from the longitudinal direction of the main body portion 20 is provided. The latching portion 25 is provided with a projecting length that reaches the back side of the connecting member 7 of the slider body 1. The part is provided with a latching protrusion 27. Therefore, the latching protrusion 27 provided on the latching head 26 is engaged with the engagement recess 15 (see FIG. 3B) provided on the back surface side of the connecting member 7 of the slider body 1, thereby pressing. The free end 23 of the member 2 can be securely hooked.

  Here, the pressing member 2 of the present embodiment is made of synthetic resin such as plastic as a whole, and the latching portion 25 is elastically deformable when latched. That is, when the latching portion 25 is inserted into the insertion hole 14 of the slider body 1, a part of the latching head 26 that faces the inner surface of the engagement hole 14 is formed on the inner surface of the engagement hole 14. It comes into contact and is elastically deformed so as to widen the latching portion 25 (to push it outward). And when the latching head 26 advances to the position beyond this engagement hole 14, the latching | locking part 25 will be decompress | restored by elastic force, and the latching head 26 will contact | abut on the back side of the to-be-latched part 73. Thus, the latching protrusion 27 can be engaged with the engaging recess 15.

  Since the embodiment of the present invention is configured as described above, the usage mode of the present embodiment is as follows. That is, the slider main body 1 and the pressing member 2 are previously integrated by pivotally supporting the shaft portions 21 and 22 of the pressing member 2 by the support means 3 and 4 of the slider main body 1 in advance. When sliding along the scale member BP, the entire slider SL is allowed to move simultaneously. In this state, the elongated member BP is inserted into the insertion holes 11 and 12 of the slider body 1, and the inner surfaces of the insertion holes 11 and 12 and the sliding contact portion 13 of the slider body 1 are slid onto the surface of the elongated member BP. Make contact. At this time, the pressing member 2 does not press the long member BP. That is, the contact side wall surface portion 20 e of the main body portion 20 of the pressing member 2 is not in contact with the connecting member 7 of the slider main body 1.

  As described above, in a state where the pressing member 2 is not pressed, the slider body 1 is not locked to the thread of the long member BP, and can freely slide along the axis. It becomes. In this state, it moves to a position to be locked, and then locks by pressing by the pressing member 2. That is, of the main body portion 20 of the pressing member 2, the shaft portions 21 and 22 are rotated so that the abutting side wall surface 20 e abuts on the connecting member 7 of the slider main body 1. This rotation is performed artificially. And when the contact side wall surface 20e contacts the connecting member 7, the thread groove forming portion 24 formed on the contact side wall surface 20e does not contact the sliding contact portion 13 of the long member BP. It abuts against the portion (the opposite surface slidably contacted by the slidable contact portion 13) and engages the thread groove FS with the thread MS of the long member BP. Due to the engagement between the thread groove FS and the screw thread MS, the slider SL as a whole is restricted from moving in the axial direction of the long member BP, and the slider SL is locked to the long member BP. It is.

  Furthermore, in the state engaged as described above (that is, the locked state of the slider SL), the free end 23 of the pressing member 2 is strongly pressed, so that the latching portion 25 provided on the free end 23 The latching head 26 is pushed out to the back side of the coupling member 7 of the slider body 1 together with the tip, and the coupling member 7 is latched by the latching head 26. By this latching, the above-described latched state of the slider SL is maintained, so that a series of operations for latching is completed.

  Moreover, the state which can be latched by the latching part 25 as described above means that the pressing member 2 sufficiently presses the long member BP. That is, since there is a thread portion (a portion rising at the boundary between one thread groove and the adjacent thread groove) around the thread groove FS formed in the thread groove forming portion 24, When the thread portion contacts the thread MS of the long member BP (that is, when the engagement is insufficient), the gap corresponding to the height of the thread portion of the thread groove forming portion 24 is pressed against the slider body 1. It exists between the member 2. Due to this gap, the latching head 26 cannot enter the engagement hole 14 (that is, it cannot be latched). Therefore, it is possible to determine whether or not the engagement state is good depending on whether or not the engagement state is possible.

  In this embodiment, the locked state can also be released. That is, when releasing the locking state, the pressing member 2 can be rotated by releasing the locking by the locking head 26, and by this rotation, the screw groove forming portion 24 of the pressing member 2 can rotate. It is only necessary to release the engagement of the long member PB. At this time, the latch head 26 can be released by forcibly elastically deforming the latch portion 25, and the latch head portion 26 is moved away from the back side of the connecting member 7. The tip can be pushed with a fingertip or the like. In the latching state, the latching protrusion 27 is engaged with the engagement recess 15, but the latching portion 25 is deformed so that the latching head 26 is separated from the back side of the connecting member 7. Thus, the latching protrusion 27 can be detached from the engaging recess 15.

  Since embodiment of this invention is as above-mentioned, it can utilize for each direction as a locking device of the member which should be locked to the elongate member which has a screw thread. For example, it can also be used as a mounting device for an operation transmission cable disclosed in Japanese Utility Model Laid-Open No. 63-195410 (Patent Document 1). In this case, the slider SL of this embodiment can restrict the movement of the other member by being connected to the other member on the back side of the connecting member 7 provided in the slider body 1. Therefore, the motion transmission cable can be locked by connecting the slider SL to the fixed side.

  Furthermore, it can also be used for a tube fixing device as shown in FIG. In this case, as the long member, two bolts B1 and B2 standing on the base part BS of the fixing device are appropriate. Then, a pipe receiving part PR formed of an arcuate belt is connected to the back side of the connecting member 7 of the slider body 1 so that the pipe receiving part PR is directed in the axial direction of the bolts B1 and B2. After moving up and down and adjusting the height appropriately, it can be locked at that height.

  In use, when the slider SL of this embodiment is independently locked to the long member BP, the slider SL is free to move (rotate) in the circumferential direction with respect to the long member BP. There is a possibility that the screw groove FS engaged with the rotation of the screw thread FS and the screw thread MS are screwed in the same manner as in the state where they are screwed together. Therefore, when the long member BP is on the fixed side, it is preferable that the slider SL cannot rotate as in the case of the two long members BP as shown in FIG.

  The embodiments of the present invention are as described above, but the present invention is not limited to these embodiments, and can take various forms within the scope of the gist of the present invention. For example, as shown in FIG. 5, it is good also as a structure which provides the projection part 28 which protrudes slightly from the upper surface part 20c of the press member 2. As shown in FIG. The protruding portion 28 is a position where the pressing member 2 does not contact the upper plate-like member 5 in a state where the pressing member 2 does not press the long member BP (non-pressing state), and the contact side wall surface portion of the pressing member 2 When 20e approaches the connection member 7, it is provided in the position which can be slidably contacted with the lower surface part of the upper plate-shaped member 5. FIG. By providing such a projection 28, the non-pressed state by the pressing member 2 can be maintained. That is, in the non-pressed state by the pressing member 2, the pressing member 2 can freely rotate around the shaft portions 21 and 22, so that the pressing member 2 rotates for some reason, and the long member BP Where there is a possibility that the thread groove forming portion 24 may come into contact with the surface, the protruding portion 28 can function as a stopper by contacting the edge of the plate-like member 5, and the pressing member 2 is rotated unexpectedly. It can be prevented from moving. When the pressing member 2 is locked to the long member BP (locking state), the protruding portion 28 slightly projecting by forcibly turning the pressing member 2 is a plate-like member. The contact with the end edge of 5 is easily released. At this time, the projecting portion 28 comes into sliding contact with the lower surface of the plate-like member 5, and a frictional resistance is given to the rotation of the pressing member 2, so that the rotation speed can be reduced.

  Furthermore, as shown in FIG. 5, the plate-like member 5 may be provided with a protrusion accommodating hole 16 that allows the protrusion 28 to be engaged and accommodates the protrusion 28. In the case of such a configuration, the protruding portion receiving hole 16 is provided at a position where the protruding portion 28 can be received when the pressing member 2 is sufficiently rotated and reaches the state where it can be locked to the long member BP. desirable. By comprising in this way, the range which should rotate the press member 2 becomes clear, and positioning of the suitable press state by the press member 2 is enabled.

  In addition, although the positional relationship between the protrusion 28 and the protrusion receiving hole 16 enables positioning in the pressed state by the pressing member 2, it may function as positioning in a non-pressed state. That is, in FIG. 5, the position of the protruding portion 28 in the non-pressed state is the outside of the plate-like member 5, but is provided at a position where the protruding portion 28 is always in sliding contact with the lower surface of the plate-like member 5. It is also possible to provide a configuration in which a second protrusion accommodating hole that can accommodate the protrusion 28 is provided at an appropriate position.

  Moreover, there can exist the following forms as modifications other than the above. That is, in the above-described embodiment, the slider body 1 is configured such that the two plate-like members 5 and 6 are arranged with an appropriate interval (interval where the pressing member 2 can be stored), and the pressing member 2 is stored therebetween. However, the pressing member 2 is not limited to the configuration housed in the slider body 1, and is limited to the configuration configured by the plate-like members 5 and 6. not. For example, in the above embodiment, the ribs 51, 52, 53, 61, 62, and 63 are provided on the plate-like members 5 and 6 so as to ensure the strength and the sliding contact area. Alternatively, two rectangular parallelepipeds may be used, and the entire structure may be configured as a large rectangular parallelepiped, and a portion necessary for contact with the pressing member 2 may be cut out.

  Furthermore, only the form in which the plate-like members 5 and 6 are two has been described, but three or more plate-like members 5 and 6 may be used. In this case, a plurality of pressing members 2 can be used as long as they are arranged between the respective plate-like members with appropriate intervals. Furthermore, it can also be set as the form which selects the arbitrary clearance gaps among several clearance gaps, and mounts the press member 2. FIG.

  In the above-described embodiment, the slider body 1 and the pressing member 2 are provided separately, and the shaft members 21 and 22 of the pressing member 2 are supported by the support means 3 and 4 of the slider body 1, so that the pressing member 2 is The slider body 1 and the pressing member 2 may be integrally formed, although the structure is provided so as to be rotatable. As such a form, as shown to Fig.6 (a), it may be set as the structure formed by connecting the one side wall surface 30a and the press member 2a of the slider main body 1a with the thin strip | belt body 40a. In this way, by connecting the two with the thin band member 40a, the pressing member 2a can be inserted between the plate-like members 5a and 6a of the slider body 1a by curving the thin band member 40a. . In this case, in order to maintain the engagement of the long member BP by the pressing member 2a, the coupling member 7a of the slider body 1a is provided with two engagement holes 14a and 14a, and two engagement holes are simultaneously engaged with these. Hooks 25a and 25a are provided on the pressing member 2a. These two sets of engaging holes 14a, 14a and latching portions 25a, 25a are respectively arranged on both sides of the long member BP or the thread groove forming portion 24a, thereby forming a thread groove for the long member BP. The pressing state of the part 24a can be made favorable.

  Further, as a form in which the slider body 1 and the pressing member 2 are integrally formed, as shown in FIG. 6B, the one-side wall surface 30b and the pressing member 2b of the slider body 1b are replaced by a plate-like support member 40b. There may be a configuration of coupling. The support member 40b is configured such that two plate-like members 40ba and 40bb are foldable at the thin boundary portion 40bc, and one plate-like member 40ba projects from one wall surface 30b of the slider body 1b. The other plate-like member 40bb is provided so as to protrude from the pressing member 2b. With this configuration, the pressing member 2b can be inserted between the plate-like members 5b and 6b constituting the slider body 1b by bending at the thin boundary portion 40bc. Even in such a configuration, in order to maintain the engagement of the long member BP by the pressing member 2b, the coupling member 7b of the slider body 1b is provided with two engaging holes 14b and 14b, and the pressing member In 2b, two latching portions 25a and 25a are provided on both sides of the long member BP or the thread groove forming portion 24b, respectively.

  In addition, in the form which comprises the slider main body 1 and the pressing member 2 separately, since either one (especially pressing member 2) can be replaced | exchanged, the thread of the elongate member BP When the pitch of the MS is different, the pitch of the thread groove FS of the thread groove forming portion 24 of the pressing member 2 can be changed to match with the thread ridge MS, and an appropriately engageable one can be selected. It has the advantage of being able to.
