Description

  The present invention relates to a stud locking tool suitable for attaching another mounting member to a mounted member to which a stud is fixed by locking to a stud having a screw or a circumferential groove formed on an outer peripheral surface, and in particular, a stud. It is related with the stud latch which can confirm that insertion of is sufficient.

  Stud locking devices suitable for attaching another mounting member to a mounted member to which the stud is fixed by locking to a screw stud or the like are well known. For example, a stud locking tool for holding a fuel pipe or a brake pipe of an automobile on a panel such as a vehicle body is frequently used because it does not require a hole in the panel. In the stud locking device described in Japanese Patent Application Laid-Open No. 11-141528 (Patent Document 1), the tip of the stud protrudes from the screw stud fixed to the panel while the pipe is held by the pipe holding portion. It is pushed in until the stud locking tool is locked to the stud, and the pipe held by the holding portion can be attached to the panel.

JP-A-11-141528 Japanese Utility Model Publication No. 1-089813 (No. 6-015128) JP-A-7-174127 JP-A-10-030626

  In the conventional stud locking device described in Patent Document 1 or the like, if the stud locking portion is sufficiently pressed and the stud inserted into the stud receiving space by the pressing is sufficient, the stud locking of the stud locking device The stud is sufficiently locked to the claw, but if the push is not enough, the stud is not fully locked. Become imperfect. The stud locking tool described in Patent Document 1 does not have a configuration that allows an operator to check whether or not the stud locking portion is sufficiently pushed.

  In the stud locking tool disclosed in Patent Document 2, when the stud locking portion is sufficiently pushed into the stud, the tip of the inserted stud abuts against the detection member, and an operation reaction such as an engagement sound or a vibration sound occurs. It is configured to generate a sound and notify the operator that the stud is sufficiently pushed. The configuration of Patent Document 2 is preferable in that it informs the operator that the stud is sufficiently pushed, but since it depends on the operation reaction sound, it is difficult to hear the sound such as in a noisy place or the sound. If you miss it, you may not be able to confirm it.

  In the stud locking tool of Patent Document 3, when the stud locking portion is sufficiently pressed, the tip of the stud abuts against the movable cover and the movable cover protrudes to the outside. It has the structure which makes an operator visually check that pushing of is enough. The configuration of Patent Document 3 is preferable in that the operator can visually confirm that the stud is sufficiently pushed, but there is a possibility that confirmation may be difficult when the movable cover is hidden or in a narrow place, and there is room for improvement. .

  In the stud locking device of Patent Document 4, when the coil spring is formed in the stud locking portion and the stud spring is sufficiently pushed, the tip of the elastic locking piece that engages with the stud is compressed when the coil spring is compressed. And the locking force of the elastic locking piece to the stud is increased. The stud locking tool of Patent Document 4 is also provided with a configuration for detecting that the pushing into the stud is sufficient by clicking sound or touch when the tip of the elastic locking piece is inserted into the opening. Such a detection configuration may not be confirmed when the click sound or touch is missed.

  Accordingly, an object of the present invention is to provide a stud locking tool that can surely visually confirm that the stud locking portion is sufficiently pushed into the stud.

  In order to achieve such an object, a stud locking device according to the present invention, which is fixed to a mounted member to which a stud is fixed by being locked to a rod-like stud having a screw or a circumferential groove formed on an outer peripheral surface, A clip having a frame forming a receiving space and an elastic locking claw extending from the frame so as to be locked to the stud received in the space; and a clip slidably connected to the clip in the axial direction of the stud; Is provided with a separate clamp, which is imperfect to keep the clamp extended in the direction of insertion of the constant height stud relative to the clip if the stud received in the clip space is not fully inserted The clip has an anti-insertion piece and the clip is fixed to the clip if the stud is not fully inserted into the clip space. A holding piece that engages with the incomplete insertion prevention piece so as to keep it extended in the insertion direction of the card, and the holding piece is incompletely inserted by the stud when the stud is sufficiently inserted into the space of the clip. The clamp is configured so that the engagement with the prevention piece is released, and the clamp slides in a direction opposite to the insertion direction of the stud with respect to the clip when the holding piece is disengaged from the incomplete insertion prevention piece. It is the structure fixed to the state which does not extend, It is characterized by the above-mentioned.

  According to the above configuration, when the stud received in the space of the clip is not sufficiently inserted, the clamp is maintained in a state of extending in a direction of inserting the stud at a certain height with respect to the clip. It is possible to confirm that the stud is not completely inserted, and when the stud is fully inserted into the space of the clip, the clamp is fixed so that it hardly extends from the clip. Can reliably confirm that the stud is completely inserted.

  In the stud locking device, the clamp has a box-shaped clip receiving portion that slidably receives the clip inside. When the stud is not sufficiently inserted into the clip space, the clip receiving portion is attached to the clip. On the other hand, the clip receiving portion is maintained in a state of extending in the insertion direction of the stud at a constant height, and the clip receiving portion is formed in a shape that accommodates almost the entire clip in a nested manner when the stud is sufficiently inserted into the space of the clip. . In this locking device, the pressing pieces are formed of a pair of plate-like openable members that are pushed up by the tip of the stud when the stud is completely inserted into the space of the clip. It is configured to pivot so that the engagement with the incomplete insertion preventing piece is released by raising, and the incomplete insertion preventing piece is formed of a pair of plate-like pieces extending from the clip receiving portion so as to contact the holding piece. The length of the incomplete insertion preventing piece is a length that defines the constant height at which the clamp extends with respect to the clip when the stud is not sufficiently inserted into the space.

  In the stud locking device described above, when the stud is not inserted into the space, the clamp extends to the clip in the insertion direction of the fixed height stud, but does not extend beyond the fixed height to the clip and the clamp. For this purpose, a first locking means is provided. Further, when the stud is sufficiently inserted into the space of the clip, each of the clip and the clamp is connected to and fixed to the clip so that the clamp hardly extends from the clip. Is provided. In the locking device, the second locking means of the clamp is a pair of elastic clips formed on the clip receiving portion of the clamp so as to extend in parallel with the incomplete insertion preventing piece and corresponding to the predetermined length. It is a fixed claw, and the second locking means of the clip is a pair of engaging protrusions formed on the frame of the clip. When the stud is sufficiently inserted into the space of the clip, the engaging protrusion is clipped It is preferable to snap-engage with the fixed claw and generate a click feeling.

  In the stud locking device described above, when the clip is pushed into the stud so that the stud is received in the space of the clip, the clamp is pushed by the first pushing force so that the elastic latching claw of the clip is elastically engaged with the stud. However, when the stud is inserted into the space and the engaging protrusion engages with the clip fixing claw, the clamp is pressed into the clip with the second pressing force, and the engaging protrusion and the clip fixing claw are The pushing force of is required to be larger than the first pushing force. Further, the clamp is formed with a clip receiving portion as a clip receiving portion, and a holding portion for holding an elongated attachment member such as a pipe is provided adjacent to the clip receiving portion. Thus, the mounting member can be mounted on the mounted member using the stud locking tool according to the present invention.

  Hereinafter, a stud locking tool 1 according to an embodiment of the present invention will be described with reference to the drawings. 1 to 6 show the stud lock 1 in a state in which the stud is not inserted or not inserted completely. 7 to 9 show the stud locking tool 1 in a state where the stud is completely inserted. The stud locking tool 1 is fixed to a member to be attached such as a panel, and is clipped to a rod-shaped stud having a screw or a circumferential groove formed on the outer peripheral surface thereof. The clamp 3 is configured to hold the mounting member on the mounted member. The clip 2 and the clamp 3 are formed as separate parts and are integrally formed of a hard plastic material. The clip 2 is fixed to the mounted member by being locked to the stud fixed to the mounted member. The clamp 3 is connected to the clip 2, and the attachment member can be attached to the attachment member via the clip 2. In the illustrated embodiment, the clamp 3 holds an attachment member such as a pipe. As shown in the embodiment, the clamp 3 clamps a plurality of pipes. However, the clamp 3 is not limited to this, and the clamp 3 may have any shape, structure, or structure as long as the clamp 3 is connected to the clip 2 locked to the stud. It may have a function.

  1 to 6, the clip 2 is engaged with the frame 6 that forms a housing having a space 5 for receiving a rod-shaped stud having a screw or a circumferential groove formed on the outer peripheral surface, and the stud received in the space 5. And an elastic locking claw 7 extending from the frame 6. The frame 6 constitutes the housing of the clip 2 and forms a stud receiving space 5 inside. In the illustrated embodiment, the frame 6 is opposed to the pair of plate-like wall portions 9 extending vertically so as to face each other, a plate-like bottom portion 11 having a stud receiving opening 10 (FIG. 3), and the bottom portion 11. And an upper portion 13 formed to form a housing for the clip 2 that is locked to the received stud and secured to the attached member. In the illustrated embodiment, the frame 6 forms a rectangular parallelepiped clip 2. From each wall portion 9 of the frame 6, a pair of elastic locking claws 7 that are locked to screws or peripheral grooves on the outer peripheral surface of the stud extend obliquely toward the center of the space 5. 7 is elastically locked to the stud received in the space 5 from the stud receiving opening 10. In the illustrated example, the elastic locking claws 7 are formed as a pair of plate-like pieces, but can be selected in any shape and number. Further, the frame 6 has a pair of posts 14 extending vertically in the center between the pair of wall portions 9 so as to reinforce the strength of the clip 2.

  The clamp 3 is connected to the clip 2 so as to be slidable in the axial direction of the stud received in the space 5 of the clip 2. The clamp 3 includes a clip receiving portion 15 formed so as to receive the clip 2. Further, in the embodiment, the clamp 3 holds a plurality of pipes provided on a side portion and an upper portion adjacent to the clip receiving portion 15. Each of the pipe holding portions 17 having the portion 17 is formed by a substantially U-shaped trough 18 opened upward, and an elastic wing 19 extending obliquely from the upper portion toward the bottom surface is formed so as not to escape the pushed-in pipe. I am doing so. Such a pipe holding portion 17 is not essential for the stud locking device of the present application, and may be a holding portion that holds another attachment member, or may be one without a holding portion.

  The clip receiving portion 15 of the clamp 3 has a box shape that receives the clip 2 inside so as to be slidable, and is formed in a shape that can accommodate almost the entire clip 2 in a nested manner. Specifically, as shown in FIGS. 2 to 4, the clip receiving portion 15 includes a pair of wall portions 21 and another pair of wall portions 22 so as to surround a rectangular parallelepiped housing formed by the frame 6 of the clip 2. It is formed.

  The clamp 3 is imperfect to keep the clamp 3 extending in the direction of inserting the stud at a fixed height relative to the clip 2 when the stud received in the space 5 of the clip 2 is not fully inserted. An insertion preventing piece 23 is provided. As shown in FIG. 4, a pair of incomplete insertion prevention pieces 23 are formed inside the post 14 of the clip 2, and are obstructed by the post 14 when the clamp 3 slides to receive the clip 2. There is no. Each of the incomplete insertion preventing pieces 23 extends from the upper part to the lower part of the stud receiving part 15, and the length of the incomplete insertion preventing piece 23 extends to the clip 2 when the stud is not sufficiently inserted into the space 5. The length is set to determine the certain height. Therefore, the incomplete insertion preventing piece 23 has a function of maintaining the clamp 3 in a state of extending in the insertion direction of the stud at a certain height with respect to the clip 2 when the stud received in the space 5 of the clip 2 is not sufficiently inserted. Have. The insertion direction of the stud is the direction shown by the arrow 25 in FIG. In many cases, the mounted member to which the stud is fixed is large, and it is difficult to insert the stud into the stud locking device 1, so that the stud locking device 1 is against the stud fixed to the mounted member. The stud 2 is pushed into the space 5 of the clip 2 so as to receive it. The pushing operation of the stud locking tool 1 is relatively the same as the stud being pushed into the space 5 of the clip 2, so in this document, the direction of the arrow 25 is defined as the stud insertion direction.

  In the clip 2, when the stud is not sufficiently inserted into the space 5, the clamp 3 is kept at the lower end of the incomplete insertion preventing piece 23 in order to keep the clamp 3 extending in the insertion direction of the stud at a constant height with respect to the clip 2. A pair of pressing pieces 26 to be engaged are provided. When the stud is not sufficiently inserted into the space 5 due to the engagement between the holding piece 26 and the lower end of the incomplete insertion preventing piece 23, the clamp 3 extends in the insertion direction of the constant height stud with respect to the clip 2. Maintained. The holding piece 26 is formed of a pair of plate-like members that can be opened and closed that are pushed up by the tip of the stud when the stud is completely inserted into the space 5. As shown in FIG. 4, each pressing piece 26 is formed in a horizontal plate shape that extends over the stud receiving space 5 between the lower ends of the two incomplete insertion preventing pieces 23. As shown in FIGS. 5 and 6, each pressing piece 26 extends from the upper part 13 of the frame 6 of the clip 2 to a position (FIG. 5) that contacts the lower end of the incomplete insertion preventing piece 23. It is formed as a plate-like member that can be swung so that the stud 27 is pushed up by the tip of the stud (arrow 29) when the stud 27 is completely inserted into the space 5 from a position that contacts the lower end of the prevention piece 23. Each pressing piece 26 pivots so that the engagement with the lower end of the incomplete insertion preventing piece 23 is released by raising the stud 27. When the pressing piece 26 is disengaged from the incomplete insertion preventing piece 23, the holding piece 26 as a stopper of the incomplete insertion preventing piece 23 is eliminated. The clip 2 can be slid in the opposite direction, and the clip 2 is accommodated in the clip receiving portion 15 of the clamp 3 and fixed so as not to extend from the clip 2 almost. Such a fixed state is shown in FIGS. As shown in FIG. 5, the holding piece 26 that contacts the lower end of the incomplete insertion preventing piece 23 is selected to have the same shape and length as the radius (R) at the time of turning. The turn (the arrow 29 in FIG. 6) is performed smoothly. Moreover, even if the force that pushes the clip 3 into the clip 2 by mistake when the clamp 3 is transported in the state where it is assembled to the clip 2, the pressing piece 26 only falls in the direction opposite to the arrow 29, The incomplete insertion preventing piece 23 is maintained in contact with the holding piece 26, and the clip 2 does not enter the clamp 3.

  The clamp 2 and the clamp 3 are connected to each other so that they can be handled as one component even when the stud is not inserted into the space. Therefore, each of the clip 2 and the clamp 3 is provided with first locking means that locks each other. The first locking means of the clip 2 is a pair of elastic connecting claws 30 extending upward from the upper part of the wall portion 9 of the frame 6. The first locking means of the clamp 3 is a pair of locking shoulders 31 that locks with a connecting claw 30 formed at the lower part of the clip receiving portion 15. In order to connect the clip 2 to the clamp 3, the connecting claw 30 may be inserted into the clip receiving portion 5 and locked to the locking shoulder 31. The clip 2 is connected to the clamp 3 by connecting the connecting claw 30 to the locking shoulder 31. Further, since the holding piece 26 abuts the lower end of the incomplete insertion preventing piece 23 by this connection, the clamp 3 extends to the clip 2 in the insertion direction of the constant height stud, but does not extend beyond the certain height. Connected in state. By this connection, the clamp 2 and the clamp 3 can be handled as one part.

  Each of the clip 2 and the clamp 3 is connected and fixed to the clip 2 so that it hardly extends from the clip 2 when the stud is sufficiently inserted into the space 5 of the clip 2. For this purpose, a second locking means is provided. The second locking portion means of the clip 2 is a pair of engaging projections 33 provided on the upper portion of the wall portion 9 of the frame 6 adjacent to the elastic coupling claw 30. The second locking means of the clamp 3 has a length corresponding to the predetermined length in parallel with the incomplete insertion preventing piece 23 (not the length of the incomplete insertion preventing piece 23 but the length in which the stud is completely inserted). That is, a pair of elastic clip fixing claws 34 formed on the clip receiving portion 15 extending a length corresponding to the predetermined length). As shown in FIGS. 5 and 6, the clip fixing claw 34 has a taper portion 37 taper inward so that the frictional engagement to the side surface becomes stronger as the engagement protrusion 33 approaches the locking portion 35 at the tip. is there. When the engaging protrusion 33 approaches the locking portion 35 of the clip fixing claw 34, the tip of the clip fixing claw 34 is bent outward, and when the engaging protrusion 33 reaches, the original posture is restored and engaged. The mating protrusion 33 snaps to the locking portion 35 (so-called snapping) and generates a click feeling. The clamp 3 accommodates the clip 2, and the clamp 3 is connected in a state of hardly extending from the clip 2. It is fixed as it is. Therefore, when the stud is sufficiently inserted into the space 5 of the clip 2, the engaging protrusion 33 snaps to the engaging portion 35 of the clip fixing claw 34, and the click feeling is transmitted to the operator. . The clamp 3 is fixed to the clip 2 because after the clip fixing claw 34 is bent outward, the engaging protrusion 33 engages with the locking portion 35 so that the posture of the clip fixing claw 34 is restored. Therefore, it becomes a strong connection.

  The pushing force for the engaging projection 33 to engage with the locking portion 35 of the clip fixing claw 34 is to receive the stud into the space 5 of the clip 2 and push the clip 2 as it is, and the stud engages with the elastic locking claw 7. It is set to be larger than the pushing force when traveling together. Here, the force when the clip 2 is pushed into the stud so that the stud is received in the space 5 of the clip 2 and the elastic locking claw 7 is elastically engaged with the stud is set as the first pushing force, The pushing force when the engagement protrusion 33 is engaged with the locking portion 35 of the clip fixing claw 34 as the insertion proceeds is set as the second pushing force. The engaging protrusion 33 and the clip fixing claw 34 use the rigidity of the clip fixing claw 34 itself and the shape of the tapered portion 37 and the like, and the second pressing force requires a larger force than the first pressing force. It is formed as follows. Therefore, the stud is always pushed into the completely inserted state, and the engaging protrusion 33 is engaged with the clip fixing claw 34 there.

  FIGS. 7 to 9 show how the pipe 38 held by the pipe holding portion 17 of the clamp 3 is attached to the attachment member 39 such as a panel using the stud locking tool 1 having such a configuration. In the mounting operation, first, a large number of pipes 38 are pushed and held by the trough 18 of the pipe holding portion 17 of the clamp 3 at predetermined positions. At this time, since the stud 27 is not inserted into the clip 2, the incomplete insertion preventing piece 23 is engaged with the holding piece 26, and the clamp 3 is attached to the clip 2 as shown in FIG. 2. The fixed height studs are connected so as to extend in the insertion direction of the studs. Next, in a state where a plurality of pipes 38 are attached at predetermined positions of the clamp 3, the stud locking device 1 is attached to which a stud 27 having a screw or a peripheral groove formed on the outer peripheral surface is fixed at a predetermined position. It is carried into a position where the member 39 is located. In this carry-in, even if a force for accidentally pushing the clamp 3 into the clip 2 is applied, the stud 27 is not inserted into the clip 2, so that the incomplete insertion preventing piece 23 is maintained in contact with the holding piece 26. Thus, the clip 2 does not enter the clamp 3. The stud locking device 1 is attached by pushing the clip 2 of the stud locking device 1 into the stud 27 so that the stud 27 is received in the space 5 of the clip 2 at the position of the mounted member 39 to which the stud 27 is fixed. Press against member 39. This pushing is performed by pushing the clip receiving portion 15 of the clamp 3 or the pipe holding portion 17 of the clamp 3 or the pipe 38 toward the member 39 to be attached.

  By the above pushing, the stud 27 advances while engaging the elastic locking claw 7 in the space 5 of the clip 2, reaches the position where the tip of the stud 27 contacts the holding piece 26, and the holding piece 26 is moved. Push outward (see arrow 29 in FIG. 6). This position is a position where the stud 27 is completely pushed into the clip 2. As the holding piece 26 is spread by the stud 27, the holding piece 26 is disengaged from the lower end of the incomplete insertion preventing piece 23, and the clamp 3 holds the clip 2 so that the clip receiving portion 15 accommodates the entire clip 2. The engagement protrusion 33 snaps to the locking portion 35 of the clip fixing claw 34 and generates a click feeling, and the clamp 3 is connected to the clip 2 so as not to extend from the clip 2 and is fixed as it is. Is done. As described above, when the stud is sufficiently inserted into the space 5 of the clip 2, the operator can know the click sound and the click feeling and know when the stud is completely inserted. And since the clamp 3 is connected and fixed as it is in a state of hardly extending from the clip 2, the operator can surely confirm the complete insertion state of the stud by visual observation. Since the clip 2 is securely fixed to the attachment member 39 by the elastic locking claw 7, and the clamp 3 is securely connected to the clip 2 by the engagement of the clip fixing claw 34 and the engaging protrusion 33, the clamp 3 The pipe 38 held in the position is firmly fixed to the attached member 39.

  It can be confirmed that the pressing of the clamp 3 is insufficient even if the click feeling is not obtained, but since the clamp 3 extends to a certain height with respect to the clip 2, it can be confirmed clearly at a glance. If it is confirmed that the indentation is insufficient, further indentation may be performed, thereby ensuring that the stud is indented to a sufficient position.
