JP 2004-36080 A

  Attaching attachment members such as a locking device member to the shutter curtain can be done with a fastener such as a screw or rivet, but this fastener penetrates both the front and back surfaces in the thickness direction of the shutter curtain. If the attachment structure of the attachment member to the shutter curtain has to be operated on both the front and back surfaces of the shutter curtain, this attachment operation becomes troublesome and time-consuming, which is not preferable.

  The object of the present invention is to allow attachment work of the attachment member to the opening / closing body from only one of the front and back surfaces in the thickness direction of the opening / closing body, and to improve work efficiency. The present invention provides a mounting structure for an attachment member for an opening / closing body.

  The attachment structure for an attachment member for an opening / closing body according to the present invention is the attachment structure for the attachment member for an opening / closing body for attaching the attachment member for the opening / closing body to the opening / closing body for opening / closing the opening. A screw member that is screwed into the formed screw hole, passes through the screw hole, and has a tip that contacts the opening / closing body, and a screw member that is formed on the opening / closing body and the tip contacts the opening / closing body. Thus, the screw member includes an abutting portion for abutting the attached member moved in a direction opposite to the forward direction of the screw member.

  In this attachment structure of the attachment member for the opening / closing body, when the screw member is screwed through the screw hole formed in the attachment member and the tip of the screw member hits the opening / closing body, the screw member is further rotated. The attachment member moves in the direction opposite to the forward direction of the screw member, and this movement causes the attachment member to contact the contact portion formed on the opening / closing body, whereby the attachment member is Is attached to the opening / closing body by a clamping action by the contact portion.

  And the attachment operation | work to such an opening / closing body of such an attachment member performs the operation | work which rotates a screw member from the one surface in which the said contact part is formed among the front and back both surfaces of the thickness direction of an opening / closing body. Therefore, it is not necessary to attach the attachment member to the opening / closing body on both the front and back surfaces in the thickness direction of the opening / closing body. It becomes possible to plan.

  In addition, since the screw member does not penetrate both the front and back surfaces of the opening / closing body, the other surface of the opening / closing body in the thickness direction where the contact portion is not formed is, for example, a smooth surface. Thus, the appearance of the opening / closing body can be improved.

  The screw member may be a screw or a bolt, and may be any member having a male screw formed on the outer peripheral surface as long as it is screwed into and penetrates the screw hole described above.

  Further, the part of the opening / closing body to which the tip of the screw member hits may be a part of the opening / closing body itself, or a member arranged on the opening / closing body.

  In the present invention described above, the surface of the part of the opening / closing body to which the tip of the screw member abuts may be a flat surface or a rough surface with small irregularities.

  According to the latter, the tip of the screw member that is screwed into the screw hole of the accessory member and hits the portion provided on the opening / closing body with a rough surface, and the rough surface is the tip of the screw member For example, the screw member can be prevented from rotating in a loosening direction due to an impact at the time of opening / closing movement or closing of the opening / closing body. The attachment of the attachment member to the opening / closing body by the clamping action with the contact portion can be performed more reliably.

  In the present invention, the number of abutting portions may be one or plural. That is, the number of contact portions may be at least two of the first contact portion and the second contact portion that are provided with an interval.

  As described above, when the number of the abutting portions is a plurality provided at intervals, a screw member for each abutting portion may be prepared.

  In addition, when the number of the contact portions is at least two of the first contact portion and the second contact portion that are provided at an interval, the second contact portion is more than the first contact portion. In addition, the opening / closing body may be provided with a clamping portion for clamping the attachment member together with the second contact portion.

  According to this, since the second contact portion sandwiches the attachment member together with the sandwiching portion, it is not necessary to prepare a screw member for the second contact portion, thereby reducing the number of screw members, A reduction in the number of man-hours for rotating the screw member that must be carried out can be achieved.

  Further, as described above, when the opening / closing body is provided with a sandwiching portion for sandwiching the attachment member together with the second contact portion, the surface of the sandwiching portion that comes into contact with the attachment member has a small unevenness. It may be a rough surface provided.

  According to this, since the rough surface of the sandwiching portion generates a large frictional force with the attachment member, the attachment of the attachment member between the second contact portion and the sandwiching portion is further ensured. Can be.

  The attachment structure according to the present invention can be applied to any member that is attached to the opening / closing body as an attachment member, and an example of the attachment member is a member for a locking device that is attached to the opening / closing body in order to lock the opening / closing body. In another example, the attachment member is a holding member for holding an operation member such as a gripping member provided on the opening / closing body so as to be slidable or a window frame member provided on the opening / closing body. In addition, when the opening / closing body is a shutter curtain of a shutter device, and a retaining member for preventing the shutter curtain from coming off from the guide rail that guides the opening / closing movement of the shutter curtain is attached to the shutter curtain, this The attachment structure according to the invention can be applied to attach the retaining member to the shutter curtain.

  Moreover, when applying the attachment structure based on this invention to the member for locking devices attached to an opening / closing body in order to lock an opening / closing body, this locking device may be by arbitrary forms and structures.

  The locking device of the example is disposed on a locking member that is movably disposed on the opening / closing body and a non-moving member that is stationary with respect to the opening / closing body, and the locking member can be locked and detached. In addition, the locking member is locked, the opening / closing movement of the opening / closing body is prevented, the locked member to which the opening / closing body is locked, the locking device main body is disposed on the opening / closing body, and the operation member is operated And a locking device that has a locking member that moves relative to the locking device main body, and that is selected by the locking member to lock and release the locking member with respect to the locked member. . In such a locking device, the locking device member as the accessory member can be a lock device main body or a base member coupled to the lock device main body.

  In another example, the locking device is disposed on a locking member that is movably disposed on the opening / closing body, and on a non-moving member that is stationary with respect to the opening / closing body. The locking member is locked to prevent the opening / closing movement of the opening / closing body so that the opening / closing body is locked.

A bar member 14 is connected to each lock member 12 via a connecting member 13, and a tip portion of each bar member 14 is slidable inside a guide member 15 disposed at a longitudinal end portion of the slat 9 </ b> B. Has been inserted.

  Further, the connecting member 13 is guided by a guide member 51 attached to the slat 9B and is linearly movable in the left-right direction. Therefore, the connecting member 13 is a moving member in the present embodiment. Yes.

  3 is a partially enlarged view of FIG. 2 showing a portion of the above-described guide member 15, and FIG. 4 is a sectional view taken along line S4-S4 of FIG. As shown in FIG. 3, the guide member 15 is bent by inserting a protrusion 17 </ b> A of the base member 17 fixed to the slat 9 </ b> B with a fixing device 16 such as a rivet into the hole 15 </ b> A of the guide member 15. Thus, it is attached to the slat 9 </ b> B via the base member 17. Further, as can be seen from FIGS. 3 and 4, the guide member 15 is open to the slat 9 </ b> B side and has a cross-sectional hat shape in which the tip of the bar member 14 is slidably inserted. In addition, the slide member 18 is also slidably accommodated.

  As shown in FIG. 4, the slide member 18 has an elongated box shape in which an end portion on the guide rail 4 side and a surface on the slat 9B side are opened, and the guide rail 4 of the slide member 18 is formed. An end surface wall portion 18A is provided at the end opposite to the side, and this end surface wall portion 18A is formed at the front portion of the bar member 14 and a spring storage space portion 14A in which the coil spring 19 is stored. Is inserted inside. The spring housing space portion 14A of the bar member 14 is formed to include a front wall portion 14B and a rear wall portion 14C that are both sides of the lock member 12 in the forward / backward movement direction. The coil spring 19 is disposed between the rear wall portion 14 </ b> C of the bar member 14 and the end surface wall portion 18 </ b> A of the slide member 18.

  As described above, the slide member 18 has an elongated box shape in which the end portion on the guide rail 4 side and the surface on the slat 9B side are opened, and therefore the side surface portion 18B of the slide member 18 shown in FIG. Are on both sides in the up-down direction, which is the opening / closing movement direction of the shutter curtain 1, and holes 20 are formed in these side surface portions 18B. A projection 21A formed on a locking member 21 whose rear portion is inserted into the guide member 15 is inserted into these holes 20, and the locking member 21 is a shutter curtain centering on the projection 21A. 1 is swingable in the thickness direction.

  As can be seen from the structure described above, the locking member 12 of the locking device 11 shown in FIG. 2 has a locking member 21 via a connecting member 13, a bar member 14, a coil spring 19, and a slide member 18. It is connected. Therefore, when the lock member 12 performs a movement that protrudes from the lock device main body 11A, in other words, when the lock member 12 moves forward relative to the lock device main body 11A, the above-described moving member is obtained. As the connecting member 13 moves, the slide member 18 and the locking member 21 are also moved forward to the guide rail 4 side by the coil spring 19 compressed by the rear wall portion 14C of the bar member 14 as shown in FIG. The forward movement of the member 21 is performed while the locking member 21 riding on the raised portion 17B formed on the base member 17 swings in the thickness direction of the shutter curtain 1 around the protruding portion 21A. Further, when the lock member 12 performs a retreating movement with respect to the lock device main body 11A, in other words, when the lock member 12 moves backward with respect to the lock device main body 11A, it is shown in FIG. As shown, when the front wall portion 14B of the bar member 14 comes into contact with and pulls the end surface wall portion 18A of the slide member 18, the locking member 21 is also retracted from the guide rail 4 side.

  As shown in FIGS. 3 to 5, a locked member 22 to which the shutter curtain 1 is locked when the locking member 21 is locked is fixedly arranged inside the guide rail 4. As shown in FIG. 3, the locking member 21 according to the present embodiment has a rake shape in which three convex portions 21 </ b> B are formed at the distal end portion on the guide rail 4 side. As shown in FIG. 5 and FIG. 5, the locked member 22 is formed with two rising wall portions 22A on both sides in the thickness direction of the shutter curtain 1, and each of these rising wall portions 22A has As shown in FIG. 3, three recesses 22B are provided.

The protrusion 21B is inserted into the three recesses 22B of the locked member 22, whereby the locking member 21 is locked to the locked member 22 and reaches the fully closed position in FIG. Is locked. As shown in FIG. 4, when the locking member 21 moves backward, the locking member 21 is detached from the locked member 22, and the shutter curtain 1 is unlocked.

  Note that the forward movement of the locking member 21 toward the guide rail 4 is performed by compressing the coil spring 19 as described above. Therefore, the engagement member 21 is engaged by a large elastic pressure due to the compression spring force of the coil spring 19. The stop member 21 can be strongly pressed against the locked member 22. When the locking member 21 moves forward, if the convex portion 21B of the locking member 21 does not coincide with the concave portion 22B of the locked member 22, the coil spring 19 is compressed and the shutter curtain 1 is moved. When the convex portion 21B of the locking member 21 and the concave portion 22B of the locked member 22 coincide with each other by slightly moving up and down, the locking member 21 moves forward by the compressed repulsive force of the coil spring 19, and the locking member The convex portion 21 </ b> B of 21 enters the concave portion 22 </ b> B of the locked member 22.

  Further, since the three recessed portions 22B of the locked member 22 are formed on the rising wall portions 22A formed on both sides in the thickness direction of the shutter curtain 1, as shown in FIG. Even if the standing position of the two guide rails 4 is reversed left and right, the locking member 21 can be locked to the locked member 22.

  FIG. 6 shows the internal structure of the locking device 11 shown in FIGS. 1 and 2. 6 is a view seen from the front side of the shutter device (the surface side of the slat 9B), as in FIG. 1, and a pinion member 23 is rotatably disposed inside the lock device main body 11A. . Further, as shown in FIG. 2, a thumb turn member 24 serving as a manual operation member operated by hand is provided on the back surface of the lock device main body 11A. As shown in FIG. 1, the key hole 11B of the locking device 11 is exposed on the surface of the slat 9B, and is a plate (not shown) that is inserted into the key hole 11B and serves as a manual operation member that can be operated by hand. Both the key and the thumb turn member 24 shown in FIG. 2 are connected to the pinion member 23 via a connecting member such as a cylinder (not shown), and the rotation of the plate key and the thumb turn member 24 is performed. The operable range is 180 degrees.

  When either the plate key or the thumb turn member 24 is rotated 180 degrees in one direction, the pinion member 23 is also rotated 180 degrees in the same direction via the connecting member such as the cylinder. Is rotated 180 degrees in the other direction, the pinion member 23 is also rotated 180 degrees in the same direction via the connecting member such as the cylinder. As shown in FIG. 6, the pinion member 23 is formed with a plurality of teeth 23 </ b> A, and each lock member 12 of the lock device 11 is formed with a plurality of teeth 12 </ b> A that mesh with these teeth 23 </ b> A. Therefore, when either of the above is rotated 180 degrees in one direction, the lock member 12 moves forward with respect to the lock device main body 11A as shown in FIGS. As described above, the locking member 21 is also moved forward to be locked to the locked member 22, and the shutter curtain 1 reaching the fully closed position is locked. Further, when either of the above is rotated 180 degrees in the other direction, the lock member 12 moves backward with respect to the lock device main body 11A as shown in FIGS. The stop member 21 also moves backward to be disengaged from the locked member 22, and the shutter curtain 1 is unlocked. Thereafter, the shutter member 21 is put on the handle member 10 shown in FIG. The curtain 1 can be opened and moved.

  When the shutter curtain 1 is unlocked by the rotation operation of the plate key, the direction of the plate key at this time is vertical, and therefore the opening movement operation of the shutter curtain 1 is performed by the plate key. Even in this case, it is possible to prevent breakage of the plate key whose strength is increased in the opening movement direction.

  As can be seen from the above, the locking and disengaging of the locking member 21 with respect to the locked member 22 is selected by the forward and backward movement of the locking member 12 of the locking device 11, and the locking and unlocking of the shutter curtain 1 are selected. Is done. That is, when the lock member 12 of the lock device 11 moves forward and backward, the locking and unlocking of the locking member 21 with respect to the locked member 22 is switched, and thereby the locking and unlocking of the shutter curtain 1 are switched.

  In addition, when the force which rotates the pinion member 23 is input to the pinion member 23 from the lock member 12 side, the pinion is determined by the shape setting of the aforementioned tooth portions 12A and 23A of the lock member 12 and the pinion member 23. The member 23 does not rotate. Therefore, when the lock member 12 reaches the reverse position shown in FIG. 6, the locking member 21 is detached from the locked member 22 unless the above-described plate key or thumb turn member 24 is operated. When the lock member 12 has reached the advanced position shown in FIG. 7, the locking member 21 is locked to the locked member 22 unless the plate key or the thumb turn member 24 is operated. Locked to state.

  FIG. 8 shows the back surface of the lock device main body 11A on which the thumb turn member 24 is arranged. Therefore, FIG. 8 is reverse to FIG. 6 and FIG. The thumb-turn member 24 is used when the lock member 12 reaches the backward movement limit (when shown in FIG. 8) and when the locking member 12 reaches the forward movement limit (when shown in FIG. 10). 1 is a long and narrow member extending in the left-right direction, and the pinion member 23 shown in FIG. 6 or the like is rotated around a central axis provided at the center in the longitudinal direction. Therefore, as described above, it is freely rotatable by 180 degrees. When the thumb turn member 24 is rotated 180 degrees to the left in FIG. 8 as indicated by the arrow A in FIG. 8, the lock member 12 moves forward, and the locking member 21 is locked to the locked member 22.

Is formed. The convex portion 41 is shown in FIG. 9 which is a cross-sectional view taken along line S9-S9 in FIG. By processing, it is provided in the lock device main body 11A.

  Concave portions 42 for accommodating the convex portions 41 are formed at both ends in the longitudinal direction of the thumb turn member 24 facing the convex portions 41 when the shutter curtain 1 is locked and unlocked. Grooves 43 extending from the recess 42 to the outer edge of the thumb turn member 24 are formed at both longitudinal ends of the thumb turn member 24. These grooves 43 are continuously formed at the locus-like portions of the thumb turn member 24 that sequentially face the convex portions 41 when the thumb turn member 24 is rotated to the left side in FIG. It has become.

  In addition, at least the peripheral portions of the recess 42 and the groove 43, that is, in the embodiment of FIG. 9, all the portions of the thumb turn member 24 facing the lock device main body 11 </ b> A except for the recess 42 and the groove 43 The protruding portion 44 (see FIG. 9) protrudes from 43 to the locking device main body 11A side, and the protruding amount of the protruding portion 44 can be brought into contact with the protruding portion 41 of the locking device main body 11A. It is a big size.

  In order to lock the shutter member 1 by locking the locking member 21 to the locked member 22, the state shown in FIG. 8 (in FIG. 8, the small protrusion-shaped instruction portion 24 A provided on the thumb-turn member 24 is provided. 8 indicates a state where the locking of the shutter curtain 1 by the locking member 21 and the locked member 22 is unlocked because it indicates “open” displayed on the lock device main body 11A. When the thumb turn member 24 is rotated 180 degrees in the direction of arrow A in FIG. 8, the thumb turn member 24 has a concave portion 42 and a groove 43 with respect to the lock device main body 11A. The projection 44 provided at least in the peripheral portion of the recess 42 abuts the projection 41 near the end of the rotation of 180 degrees. For this reason, the rotation of the thumb turn member 24 by 180 degrees is performed by the elastic deformation of the thumb turn member 24 formed of an elastically deformable material such as a synthetic resin, and the protruding portion 44 riding on the convex portion 41. By this riding, the convex portion 41 enters the concave portion 42 of the thumb turn member 24. This state is shown in FIG.

  In FIG. 10, since the small protrusion-shaped instruction portion 24 </ b> A indicates “closed” displayed on the lock device main body 11 </ b> A, the shutter curtain 1 is locked by the locking member 21 and the locked member 22. It shows the state.

  In order to release the locking member 21 from the locked member 22 and unlock the shutter curtain 1, the thumb turn member 24 in the state of FIG. 10 is rotated 180 degrees in the direction of arrow B in FIG. In this case, first, the thumb turn member 24 rotates while the protruding portion 44 of the thumb turn member 24 rides on the convex portion 41 of the lock device main body 11A due to the elastic deformation of the thumb turn member 24. Near the end of rotation, after the groove 43 of the thumb turn member 24 passes through the convex portion 41, the convex portion 41 enters the concave portion 42 of the thumb turn member 24.

  From the above, in order to release the locking member 21 from the locked member 22 and unlock the shutter curtain 1, the thumb turn member 24 in the state of FIG. 10 is moved in the direction of arrow B in FIG. When the thumb turn member 24 is rotated 180 degrees, a resistance force is generated when the protrusion 44 of the thumb turn member 24 comes into contact with the protrusion 41 of the lock device main body 11A and rides on the protrusion 41, and resists this resistance. The operator of the thumb turn member 24 rotates the thumb turn member 24. Near the end of 180-degree rotation, the groove 43 of the thumb-turn member 24 passes through the convex portion 41, and the convex portion 41 smoothly enters the concave portion 42 of the thumb-turn member 24. Then, the resistance force does not occur.

  For this reason, in this embodiment, the resistance for applying a resistance force to the rotation operation of the thumb turn member 24 by the convex portion 41 of the lock device main body 11A and the concave portion 42, the groove 43, and the protruding portion 44 of the thumb turn member 24. A force applying mechanism 45 (see FIG. 9) is configured, and this resistance applying mechanism 45 is located near the end of the forward movement of the lock member 12 for locking the locking member 21 to the locked member 22. Immediately after starting the backward movement of the locking member 12 for releasing the locking member 21 from the locked member 22 after the forward movement, a resistance force is applied to the rotation operation of the thumb-turn member 24, and the locking member 21 is engaged. Near the end of the backward movement of the locking member 12 for releasing the locking member 22 and immediately after the forward movement of the locking member 12 for locking the locking member 21 to the locked member 22 after the backward movement. , Which is assumed not to confer resistance to the rotational operation of the thumb-turn member 24.

  Therefore, after the lock member 12 reaches the forward movement limit, when the thumb turn member 24 is rotated in the direction in which the lock member 12 is moved backward, a resistance force is generated by the resistance force applying mechanism 45. It is possible to prevent the thumb turn member 24 from being rotated inadvertently or accidentally in the direction in which the member 12 is moved backward.

  As can be seen from the structure and operation of the locking device described above, the locking device body 11A of the locking device 11, the connecting member 13 connected to the locking member 12, the bar member 14 connected to the connecting member 13, A slide member 18 connected to the bar member 14 via a coil spring 19, a locking member 21 connected to the slide member 18, and a locked member 22 that locks and disengages the locking member 21.

It is provided on the upper surface of the extending portion 54A formed by extending the slat 9B in the shutter curtain thickness direction. The slat 9B is formed with a thick screw receiving portion 55 at the upper portion and a thick sandwiching portion 56 at the lower portion, and the surface 55A of the screw receiving portion 55 and the sandwiching portion 56 are formed. Since a plurality of small V-shaped grooves extending in the longitudinal direction of the slat 9B are formed on the surface 56A, the surfaces 55A and 56A have a rough surface with small irregularities.

  The first and second contact portions 53 and 54, the screw receiving portion 55, and the sandwiching portion 56 are provided on the back surface of the slat 9B on which the lock device 11 is disposed.

  Further, a gap that is the same as or slightly larger than the thickness of the base member 50 is provided in the thickness direction of the shutter curtain 1 between the second contact portion 54 and the sandwiching portion 56.

  As shown in FIG. 2, the base member 50 to which the lock device main body 11A is coupled by the two fasteners 52 has a longer horizontal and vertical dimensions than the lock device main body 11A. Screw holes 50A shown in FIG. 11 are formed in two places on the left and right of the upper part of the base member 50 that is disengaged from the lock device main body 11A. Since these screw holes 50 </ b> A are formed in the upper part of the base member 50 that is disengaged from the lock device main body 11 </ b> A, the screw holes 50 </ b> A are provided at positions higher than half the vertical dimension of the base member 50.

  In order to attach the lock device main body 11A to the slat 9B via the base member 50, first, as can be seen from FIG. 11, the upper portion of the base member 50 is placed below the first contact portion 53 from the back side of the slat 9B.
