Description

  The present invention relates to a slide lock device capable of reliably stopping a slider that slides in a predetermined direction at a predetermined position and locking the slider in a stopped state.

  Sliders that slide along a guide rail or the like are widely used in various industries. For example, in the automobile industry, a seat slider for adjusting the seating position of the seat back and forth, and a hook of a presser belt for fixing a load placed in the cargo compartment so as not to move are provided with a hook ring for hooking. A slider with a ring is used.

  As the latter slider with a ring, the following Patent Document 1 discloses a frame-like wall having a U-shaped cross section and extending by a predetermined length, and is folded inward from the periphery of the opening of the frame-like wall, and has a predetermined interval. A guide rail having a pressing wall in which a lock groove is formed, and a slider slidably held by the guide rail, the slider being a support plate placed on the upper surface of the bottom of the frame-shaped wall; A lock plate that is held so as to be able to approach and move away from the support plate via a shaft portion erected from the support plate, a cam portion installed on the upper surface of the lock plate, and protruding from the cam portion A support shaft, a D-shaped ring rotatably mounted on the support shaft, and an outer cover of the shaft portion and disposed between the support plate and the lock plate, and the lock plate is always directed toward the holding wall of the guide rail. A slide lock with a biasing spring Device is described.

When the lock plate of the slider is aligned with the lock groove and the pressing of the lock plate is stopped, the lock plate is urged by the spring and is again engaged with the lock groove, so that the locked state can be maintained.
European Patent No. 1108608

  However, the slide lock device of Patent Document 1 has a large number of parts, a complicated structure, and further, since a spring or the like must be made of metal, the weight of the entire device increases and the manufacturing cost is high. .

  Further, when the lock plate is pressed against the support plate against the urging force of the spring to slide the slider, the support plate is also pressed against the bottom of the frame-like wall of the guide rail. For this reason, the slider is slid while the support plate is in sliding contact with the bottom of the guide rail, so that it is difficult to slide smoothly with a large sliding resistance.

  Accordingly, an object of the present invention is to provide a slide lock device that has a small number of parts, is simple in structure, can be reduced in weight and reduced in manufacturing cost, and can slide smoothly with a low sliding resistance. There is to do.

In order to achieve the above object, a first aspect of the present invention includes a slider and a base member having a housing recess that holds the slider in a predetermined direction so as to be slidable.
A guide groove provided along the slide direction of the slider, and a lock recess that is disposed along the guide groove at a predetermined interval on the inner surface of the housing recess of the base member and restricts the slide movement of the slider. Is provided,
The slider has a main body having a pin insertion hole, and a pin member inserted into the pin insertion hole of the main body,
The main body is inserted into the guide groove of the receiving recess and is slidably held, and the main body protrudes inwardly from a side facing the inner side of the receiving recess and is positioned in the locking recess And an engagement piece that engages with the lock recess,
The pin member is inserted into the main body through the pin insertion hole, and is bent inward to the extent that the engagement piece does not engage the lock recess when pressed against the engagement piece by a predetermined distance. The present invention provides a slide lock device having a pressing portion.

  According to the above invention, the pin member is pushed in a predetermined distance against the elastic force of the engagement piece, and the engagement piece is bent inward so as not to engage with the lock recess. Is released and the locked state is released. In this state, the slider can be moved to a predetermined position by sliding the slider along the guide groove.

  At this time, the slider may be slid while the pin member is pushed in. However, after removing the engagement piece from the lock recess, the engagement piece is expanded and accommodated by stopping pushing the pin member. The slider may be slid while being brought into sliding contact with the inner surface of the recess.

  When the engagement piece of the slider is positioned in the lock recess, the engagement piece is elastically restored and expanded again and engages with the lock recess, so that the slider can be locked at that position.

  As described above, the slider can be locked at a predetermined position by a simple operation of pushing the pin member and sliding the slider.

  In addition, since the engagement piece provided on the slider is normally elastically expanded toward the outside of the main body and engaged with the lock recess, A spring urging in the pressing direction toward the pressing wall is not required, the number of components can be reduced, the structure can be simplified, the weight can be further reduced, and the manufacturing cost can be reduced.

  Furthermore, when the slider is slid, if the pin member is slid while being pushed in, only the guide protrusion moves while sliding in contact with the guide groove, so that the sliding resistance can be kept low and the slider is light. It can slide smoothly with force.

  According to a second aspect of the present invention, in the first aspect, the engagement piece has a distal end entering the pin insertion hole toward the inlet of the pin insertion hole of the main body. And / or the pressing portion of the pin member forms a slope, and when the pin member is pushed in a predetermined distance, the pressing portion of the pin member abuts the tip of the engagement piece via the slope. The slide locking device is configured such that the engagement piece is bent inward and comes out of the lock recess.

  According to the above invention, since the tip of the engaging piece and / or the pressing surface of the pin member forms an inclined surface, the engaging piece can be smoothly bent inward by pushing the pin member a predetermined distance. Moreover, when the pushing of the pin member is stopped, the diameter of the engaging piece can be smoothly expanded by the elastic restoring force of the engaging piece, and the pin member can be pushed back to the initial position.

  According to a third aspect of the present invention, in the second aspect of the present invention, a retaining means is provided between the pin member and the main body to hold the pin member inserted into the pin insertion hole of the main body. In a state where the pin member is held by the retaining means, the pressing portion of the pin member is in contact with the engagement piece, and the engagement piece is bent slightly inward. There is provided a slide lock device configured as described above.

  According to the invention, in a state where the pin member is held by the retaining means, the pressing portion of the pin member abuts on the engagement piece, and the engagement piece is bent slightly inward. Since the pin member is constantly urged in the pulling direction by the elastic restoring force of the engagement piece and is held by the retaining means, the engagement piece is placed in the lock recess. It is possible to prevent the pin member from rattling in a state where the external force is not applied.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, an inner surface of the lock recess of the base member and / or an outer surface of the engagement piece engaged with the lock member has a tapered portion. The slide lock device is configured such that the lock recess and the engagement piece are engaged by the tapered portion.

  According to the above invention, the inner surface of the lock recess and / or the outer surface of the engagement piece forms a tapered portion, and the lock recess and the engagement piece are engaged by the taper portion. When moved to the lock position, the locking recess and the engaging piece are engaged by the taper portion, and the rattling of the engaging piece can be prevented, and as a result, the rattling of the slider itself is suppressed, It can be locked stably at a predetermined position.

  According to a fifth aspect of the present invention, there is provided the slide lock device according to any one of the first to fourth aspects, wherein a pair of the guide protrusions are provided on both sides of the engagement piece.

  According to the above invention, since a pair of guide protrusions are provided on both sides of the engaging piece, the guide protrusions can be widely arranged along the slide direction of the slider, and the slider slide operation is stabilized. Can do. Moreover, by disposing the guide protrusions on both sides of the engagement piece, the engagement piece can be protected by preventing the engagement piece from being caught during the sliding operation.

  According to the present invention, when the pin member is pushed in a predetermined distance against the elastic force of the engagement piece and bent inward so as not to engage the lock recess, the engagement piece is released from the lock recess. It is released and unlocked, and the slider can be slid to a predetermined position. When the engagement piece of the slider is positioned in the lock recess, the engagement piece is elastically restored and engaged with the lock recess, so that the slider can be locked. That is, the slider can be locked by a simple operation of pushing the pin member and sliding the slider.

  In addition, since the engagement piece always elastically expands toward the outside of the main body and engages with the lock recess, the spring as in the cited document 1 is unnecessary, and the structure is simplified by reducing the number of parts. In addition, the weight can be further reduced and the manufacturing cost can be reduced.

  Further, since the slider can be moved by sliding only the guide protrusions in the guide groove, the sliding resistance can be kept low, and the slider can be smoothly slid with a light force.

Further, as in Patent Document 1, it is not necessary to open the side of one end in the length direction of the guide rail and insert the slider from this opening, and then close the side opening.

  The slider 40 slidably held in the receiving recess 13 of the base member 10 as described above can be locked at a predetermined position of the base member 10 or can be unlocked and slid to another position as follows. It is possible to make it.

  That is, as shown in FIG. 6A, when the lock protrusion 60 of the engagement piece 57 of the slider 40 is engaged with the lock recess 16 of the base member 10, the sliding movement of the slider 40 is restricted and stopped. Locked to state.

  In the locked state, as shown in FIG. 6, the insertion portion 72 of the pin member 70 is inserted into the main body 50 through the pin insertion hole 51a, and the pressing portion 75 at the tip of the pin member 70 is engaged with the engagement piece. The pair of engaging pieces 57 are slightly bent inward by abutting and pressing against the front end portion 59 of the 57, and this state is caused by the retaining means comprising the retaining holes 54b and the retaining protrusions 77. Maintained.

  Therefore, the pin member 70 is constantly urged in the pulling direction by the elastic restoring force of the engagement piece 57 and is held by the retaining means, so that the engagement piece 57 engages with the lock recess 16 and the external force It is possible to prevent the pin member 70 from rattling in a state in which is not acting.

  When the slider 40 is slid from the locked state, as shown in FIG. 7, the head 71 disposed on the surface of the hook portion 52 is pushed, and the urging force in the pulling direction acting on the pin member 70 is pressed. Against this, the insertion part 72 of the pin member 70 is pushed in. Then, the pressing portion 75 of the pin member 70 comes into contact with the distal end portion 59 of each engagement piece 57, and further, the pin member 70 is pushed in a predetermined distance against the elastic force of each engagement piece 57. When the distal end portion 59 of the piece 57 is pressed, the lock protrusion 60 of each engagement piece 57 is disengaged from the lock recess 16 of the base member 10, and the locked state of the slider 40 is released.

  By sliding the slider 40 along the guide groove 15 in this state, the slider 40 can be moved to a predetermined position. At this time, the slider 40 may be slid while the pin member 70 is pushed in. However, after the engagement piece 57 is removed from the lock recess 16, the pushing of the pin member 70 is stopped to stop the engagement piece 57. The slider 40 may be slid and moved in a slidable contact with the inner surface of the housing recess 13.

  When the engagement piece 57 of the slider 40 is positioned in the predetermined lock recess 16, the engagement piece 57 is elastically restored and expanded again and engages with the lock recess 16, so that the slider 40 is stopped at that position. Can be locked to the state.

  Thus, in this locking device 1, the slider 40 can be locked in a stopped state at a predetermined position by a simple operation of pushing the pin member 70 and sliding the slider 40.

  Further, since the engagement piece 57 provided on the slider 40 is normally elastically expanded toward the outside of the main body 50 and engaged with the lock recess 16, No need for a spring that urges the guide rail toward the holding wall, reducing the number of parts and simplifying the structure, further reducing weight and reducing manufacturing costs it can.

  Further, when the slider 40 is slid, the guide protrusion 62 moves while being in sliding contact with the guide groove 15. However, since the slider 40 is made of synthetic resin, compared to the case of metal. Since the sliding resistance is low and the protrusions that have entered the recesses slide, the sliding resistance can be kept low from this point, and the slider 40 can be smoothly slid and moved with a light force.

  Furthermore, in this embodiment, the engagement piece 57 has a distal end portion 59 that enters the pin insertion hole 51 a toward the entrance of the pin insertion hole 51 a of the main body 50, and the distal end portion of the engagement piece 57. 59, the outer surface forms a slope 59a, and the pressing portion 75 of the pin member 70 forms a slope 75a. When the pin member 70 is pushed a predetermined distance, the pressing portion 75 of the pin member 70 engages with the engagement piece 57. The engagement piece 57 is bent inward and comes out of the lock recess 16 (see FIG. 6A).

  As a result, by pushing the pin member 70 for a predetermined distance, the engagement piece 57 can be smoothly bent inward, and when the push-down of the pin member 70 is stopped, the engagement restoring force of the engagement piece 57 is engaged. The diameter of the joining piece 57 can be increased smoothly, and the pin member 70 can be pushed back to the initial position.

  Further, in this embodiment, the outer side surfaces on both sides in the width direction of the lock protrusion 60 of the engagement piece 57 form taper portions 60 a and 60 a, and the taper portions 60 a and 60 a are formed on the inner side surface of the lock recess 16. It is comprised so that it may engage (refer FIG.6 (b)).

  Therefore, when the slider 40 is moved to the lock position, the lock recess 16 and the engagement piece 57 are engaged with the taper portions 60a and 60a, and the engagement piece 57 can be prevented from rattling. As a result, the backlash of the slider 40 itself can be suppressed and the slider 40 can be stably locked at a predetermined position.

  Further, in this embodiment, since a pair of guide protrusions 62 are provided on both sides of the engagement piece 57, the guide protrusions 62 can be widely arranged along the sliding direction of the slider 40. Can be stabilized. Further, by disposing the guide protrusions 62 on both sides of the engagement piece 57, the engagement piece 57 can be protected by preventing the engagement piece 57 from being caught during the sliding operation.

  The lock device 1 having the above-described structure can be used as a hook, for example, by being attached to a mounted panel P disposed on the back or side of an automobile seat or on the side wall of a luggage compartment. In this case, a trim member T having a long hole-shaped opening Ta suitable for the base member 10 is arranged on the surface side of the mounted panel P (see FIG. 3). Further, a first mounting hole P1 and a second mounting hole P2 are formed in the mounted panel P, respectively. In the case shown in FIG. 8, these mounting holes P1 and P2 are arranged in a line in the left-right direction, and the hook device 1 is placed sideways on the mounted panel P so that the sliding direction of the slider 40 with respect to the base member 10 is the left-right direction. It is supposed to be fixed.

  And the base member 10 of the hook apparatus 1 is inserted in the opening part Ta of the trim member T, and the flange part 14 is engaged with the opening part Ta periphery. At the same time, the retaining hook 17 on the back side of the base member 10 is inserted into the first mounting hole P1 of the mounted panel P and engaged with the peripheral edge of the back side, and then the insertion cylinder 20 protruding from the back side of the base member 10 is inserted into the first mounting hole P1. 2 By inserting into the mounting hole P2 and engaging the pair of elastic locking pieces 22 and 22 with the rear peripheral edge of the second mounting hole P2 (see FIG. 4A), the hook device 1 is attached to the panel P to be mounted. Can be installed.

  By attaching the locking device 1 having hooks to the mounted panel P as described above, a plurality of hooks protrude from the surface of the trim member T that covers the mounted panel P. It can be used by hooking a convenience store bag or a shopping bag.

  In this locking device 1, when the slidable slider 40 is slid and brought into contact with the adjacent fixed hook 30, the inner side surface 31 a of the shaft portion 31 of the fixed hook 30 and the inner side surface 32 a of the hook portion 32. However, the side portions 54a of the shaft portion 51 of the slider 40 and the side surface 52a of the hooking portion 52 are in close contact with each other so that the shaft portions 31, 51 are integrated into one large shaft portion (see FIG. 3), and The semicircular hook portions 32 and 52 are aligned and integrated to form a substantially circular shape when viewed from the axial direction (see FIG. 8).

  Thus, since the two hooks 30 and 40 are integrated, it can be used as one hook with improved strength, and even a heavy bag B can be hooked without any problem, and is not used. The hook does not get in the way, and the appearance looks good.

  Further, in this locking device 1, when the slider 40 is brought into contact with the adjacent fixing hook 30 and the both hook portions 32 and 52 are aligned, the both hook portions 32 and 52 are formed in a substantially circular shape. Therefore, when the handle B1 or the like of the heavy bag B is hooked, it can be smoothly hooked on the circular hook portion, and the usability can be improved and the appearance can be improved. .

  Further, the description will be made in relation to hooking a heavy object. In the lock device 1, since the fixed hook 30 is integrally formed with the base member 10, the strength of the fixed hook 30 can be improved. Even a heavy object can be hooked sufficiently, and the structure can be simplified by reducing the number of parts.

  Similarly, in this locking device 1, at least one of the fixing means formed in at least two places of the base member 10 is formed at one end of the base member 10, and is provided on the periphery on the back side of the first mounting hole P <b> 1 of the mounted panel P. A retaining hook 17 that engages and retains the base member 10 is provided. That is, the retaining hook 17 engages with the first mounting hole P1 of the mounted panel P and the base member 10 is retained so that it can be securely hooked and supported even with heavy objects. Can do. Further, if the fixed hook 30 is disposed on one end side of the base member 10 on which the retaining hook 17 is formed, the hook can be supported more firmly and stably.

  By the way, a so-called convenience store bag having a handle may be used as a garbage bag in an automobile after taking out a product. However, when there is only one hook, the opening of the bag cannot be widened, which is inconvenient for throwing away trash. Therefore, it has been desired that the opening of the bag can be widened.

  On the other hand, according to the locking device 1, as shown in FIG. 9, the slider 40 is slid away from the fixed hook 30, and the adjacent hooks 30, 40 are spaced apart from each other. By hooking the handles B1 and B1 of B on the separate hooks 30 and 40, the opening of the bag B such as a convenience store bag can be widened and held, making it easier to put in dust and less likely to shake. It becomes easy to use as a bag, and convenience can be improved.

  FIG. 10 shows another example of use when the lock device 1 is used as a hook. That is, as shown in FIG. 10 (a), when the bag B such as a convenience store bag is large, the handle B1 is used by hooking the handle B1 on the hook with the bottom portion of the bag B attached to the floor F of the automobile. There are things to do. In this case, there is a possibility that the handle B1 is lifted and detached from the hook. However, since at least one hook is slidable in this hook device 1, the handle B 1 is detached from the hooks 30 and 40 by sandwiching one side of the handle B 1 between the adjacent hooks 30 and 40. Can be reliably prevented.

  FIG. 10B shows a state in which the hook device 1 is fixed to the mounted panel P in the vertical direction so that the sliding direction of the slider 40 with respect to the base member 10 is the vertical direction. In this case, since the height of the slider 40 can be appropriately changed, for example, the height of the slider 40 can be adjusted so that the bottom of the bag B such as a convenience store bag can be brought to the floor well.

  Incidentally, the alignment structure of the hooking portion 52 of the slider 40 and the hooking portion 32 of the fixed hook 30 may be the structure shown in FIG.

  That is, as shown in FIG. 11, a pair of alignment recesses 32 b and 32 b are formed on the back surface side of the hook portion 32 of the fixed hook 30 from the inner surface 32 a side, and are adjacent to the fixed hook 30. From the side surface 52a of the hooking portion 52 of the slider 40, a pair of alignment convex portions 52b and 52b, which has a shape suitable for the pair of alignment concave portions 32b and 32b, project in a tongue shape.

  When the slider 40 is slid toward the fixed hook 30 and the fixed hook 30 and the slider 40 are brought into contact with each other, the alignment convex portions 52b and 52b on the slider 40 side are fitted into the alignment concave portions 32b and 32b of the fixed hook 30. In addition, the hooking portions 32 and 52 are configured so that the concave and convex portions are aligned.

  According to the above structure, when the handle B1 of the bag B is hooked on the fixing hook 30 and the slider B is brought into contact with the handle B1 to sandwich the handle B1, the hook portions 32 and 52 are unevenly aligned. It is possible to make it difficult for the gripped handle B <b> 1 to be pulled out from between the hook portions 32 and 52.
