Description

  The present invention relates to a lock device and a joinery to which the lock device is applied.

  A fitting that supports a door such as a glass window or door so that it can be opened and closed with respect to the opening frame is provided with a plurality of engagement means between the opening frame and the door, and by operating the handle provided on the saddle Some have a locking device which switches these engaging means between an engaged state and a non-engaged state at the same time.

  For example, in a lock device provided with two upper and lower engaging means between a vertical fence located on the door-end side of the shoji and the opening frame, an operating mechanism is provided inside the vertical fence located on the door-end side. The operating mechanism is operated by a handle provided on the vertical shaft and is disposed between the two engaging means. The operating mechanism is provided with a slider corresponding to each engaging means. The slider is slid up and down with respect to the vertical gutter when the handle is operated. The individual sliders are linked to the engaging means, and the corresponding engaging means can be switched by sliding in the vertical direction.

  In the lock device configured as described above, when the handle is operated to one side from the state in which the shoji is closed with respect to the opening frame, the slider of the operating mechanism slides upward, for example, with respect to the vertical shaft, and the two engagements Each of the means is engaged with the opening frame, and the shoji can be kept closed with respect to the opening frame. On the other hand, when the handle is operated to the other side from the above state, the slider of the operating mechanism slides, for example, downward with respect to the vertical shaft, and the two engaging means are released from the opening frame, respectively. Therefore, if the shoji is moved in the opening direction, the shoji can be opened with respect to the opening frame.

  According to the joinery provided with this type of locking device, the shoji is engaged with the opening frame at a plurality of locations, so that not only the robustness can be improved, but also the airtightness of the building to be applied is improved. It can also be improved.

  Here, in the above-described locking device, since the slider is provided outside the downspout, the structure can be simplified and the assembly work can be facilitated as compared with the case where the slider is provided inside the downspout. It becomes possible. On the other hand, since the slider, which is a movable object, is exposed to the outside, the appearance quality of the joinery may be impaired. There is also a problem that foreign matters such as dust can easily enter the operating power transmission system to the slider. For this reason, conventionally, a slider whose outer surface is covered with a front cover has been provided (see, for example, Patent Document 1).

  The operation of attaching the front cover to the vertical gutter can be easily performed by fastening the cover mounting screw to the vertical gutter. Therefore, by providing the front cover, there is no possibility that the assembly workability of the joinery is impaired. However, when the fastening force of the cover mounting screw becomes excessive, the front cover may be deformed, which may hinder the operation of the slider. Of course, if the tightening torque of the cover mounting screw is accurately managed during the assembly operation, there is no fear of causing the above-mentioned problems. However, for example, when the front cover is removed from a once-assembled fitting, for example during maintenance or inspection, it is difficult to manage the tightening torque anymore. There is a possibility that good operability cannot be secured. Note that the above-described problem does not necessarily occur only when a plurality of engaging means are provided, and can also occur when only one engaging means is provided. Further, the position where the operating mechanism is provided is not limited to the vertical hook, and the same applies to the upper hook and the lower hook.

  In view of the above circumstances, an object of the present invention is to provide a lock device and a joinery that do not cause a situation in which operability is impaired due to deformation of a front cover.

  In order to achieve the above object, a locking device according to the present invention is attached to a prospective surface of a bag by a cover mounting screw, and a front cover that secures a moving space between the bag and the operating unit.

The operating mechanism includes a unit case serving as a reference, and is attached to the bag with the unit case inserted into an opening formed in the bag. A support portion is provided in contact with the prospective surface of the heel and the front cover in the moving space in a state of being attached to the heel. That.

  According to this invention, since the support portion of the unit case is interposed between the expected surface of the heel and the front cover, even if the fastening force of the cover mounting screw becomes excessive, the front cover is deformed. There is no fear of coming. Therefore, it is possible to always ensure a good slide of the slider and maintain the operability of the lock device well.

  Further, the present invention is the above-described locking device, wherein the slider has a long slot for sliding along a sliding direction, and the cover mounting screw is attached to the flange through the long slot for sliding of the slider. The support portion has a width that can be inserted into the slide long hole of the slider, and is arranged in parallel with each other along the slide direction of the slider with respect to the cover mounting screw. It is characterized by that.

  According to the present invention, the above-described operational effects can be achieved without increasing the size along the expected direction of the heel.

  Further, the present invention is the above-described locking device, wherein the unit case has a case main body screwed to the collar and a cover portion that accommodates the operation element of the operation mechanism between the case main body and the case main body. The case main body and the cover part are connected by caulking to the front cover via caulking protrusions provided respectively.

  According to the present invention, the front cover is attached to the eaves even through the unit case, and the tightening torque can be set smaller than in the case where the cover is attached only with the cover attaching screw.

  According to the present invention, in the locking device described above, the engagement means moves in conjunction with the slide of the slider, so that the relative position with the lock receiving portion provided in the opening frame is changed. In the engaged state, the lock pin is disposed at a position facing the lock receiving portion with the shoji being closed, and the lock pin is brought into contact with the lock receiving portion. In addition, while restricting the movement of the shoji in the opening direction, in the non-engagement state, the lock pin is disposed at a position retracted from the lock receiving portion with the shoji being closed.

  According to this invention, it is possible to restrict the movement of the shoji in the opening direction by bringing the lock pin interlocked with the slide of the slider into contact with the lock receiving portion of the opening frame.

  The joinery according to the present invention is characterized in that any of the above-described locking devices is applied between the opening frame and the heel.

  According to this invention, there can exist an effect similar to the locking device mentioned above.

  According to the present invention, since the support part of the unit case is interposed between the expected surface of the flange and the front cover, even if the fastening force of the cover mounting screw becomes excessive, the front cover is deformed. There is no fear of coming. Therefore, it is possible to always ensure a good slide of the slider and maintain the operability of the lock device well.

It is a metal plate-like member having a thickness. Each locking bar 120 is provided with a metal lock pin 121 at one end and a linkage hole 122 at the other end. As shown in FIG. 4A, these locking bars 120 are provided in the door of the left vertical shaft 23a in a state where the end portions where the coupling holes 122 are formed are close to each other and the lock pins 121 protrude outward. It is inserted between the front surface 23a1 and the slide guide 25 and supported so as to be slidable only along the vertical direction.

  The operating mechanism 130 controls the position of the locking bar 120 with respect to the left vertical rod 23a, and includes a unit case 131 as shown in FIGS. The unit case 131 accommodates a pinion 133 between a case main body 132 made of a metal plate provided with a pair of main body screw holes 132a and the case main body 132, and a screw escape hole 134a at a portion corresponding to the main body screw hole 132a. And a cover portion 134 made of a metal plate provided with a thin rectangular box shape, and inserted into the left vertical rod 23a from the outside of the left vertical rod 23a through the mounting opening 26. It is formed in the size that can be. The pair of main body screw holes 132a formed in the case main body 132 are female screw holes into which the handle mounting screw 33 is screwed. When the unit case 131 is inserted into the left vertical rod 23a from the mounting opening 26, a pair of main body screw holes 132a is formed. It is formed at a position corresponding to the handle mounting hole 29. The pinion 133 is a gear member having pinion teeth 133a on a part of the outer periphery, and has a rectangular fitting hole 133b into which the drive shaft 31 of the operation handle 30 is fitted. The pinion 133 is rotatably disposed between the case body 132 and the cover part 134 in a state where the fitting hole 133b is aligned with the shaft escape holes 132b and 134b of the case body 132 and the cover part 134. is there.

  The operation mechanism 130 includes a front cover 135 and a slider 136. The front cover 135 is a long metal member having a U-shaped cross section in which a cover plate portion 135a and a pair of skirt portions 135b are integrally formed. The cover plate portion 135a has a rectangular flat plate shape having a width that is slightly smaller than the interval between the bent portions 25b in the slide guide 25 and a length sufficiently larger than the width of the unit case 131. A pair of protrusion caulking holes 135c and a pair of mounting screw escape holes 135d are provided. The pair of protrusion caulking holes 135c are through-holes formed in the cover plate portion 135a, and are formed with a space corresponding to the width of the unit case 131 between them. The pair of mounting screw escape holes 135d are through holes formed with a space corresponding to the mounting screw hole 27 formed on the door end surface 23a1 of the left vertical rod 23a between them. Although not clearly shown in the drawing, the pair of protrusion caulking holes 135c and the pair of mounting screw escape holes 135d are arranged in parallel on the center line along the longitudinal direction of the cover plate portion 135a.

  The cover plate portion 135a is configured so that the caulking protrusions 132c and 134c provided on the case main body 132 and the cover portion 134 are respectively inserted into the protrusion caulking hole 135c in a state where the unit case 131 is positioned at the center in the longitudinal direction. The unit case 131 is connected by caulking. The caulking protrusions 132c and 134c protrude from both ends of the case main body 132 and the cover part 134, and are caulked to the cover plate part 135a of the front cover 135 in a state of being juxtaposed with each other. Note that the unit case 131 in which the caulking protrusions 132 c and 134 c are caulked in the protrusion caulking hole 135 c is offset with respect to the cover plate portion 135 a of the front cover 135.

  The pair of skirt portions 135b are portions extending so as to be parallel to each other from both side edge portions of the cover plate portion 135a. The part located at the center in the longitudinal direction of each skirt part 135b has a height higher than that of the slide guide 25 of the left vertical shaft 23a, while the parts located at the both ends are substantially the same as the thickness of the plate. It is configured to have the same very small height.

  The slider 136 is a metal plate-like member having a width smaller than the interval between the pair of skirt portions 135 b in the front cover 135 and a length shorter than the front cover 135, and the unit case 131 and the front cover 135. Between the two. The slider 136 has a long slot 136a for sliding along the longitudinal direction at portions corresponding to the caulking protrusions 132c and 134c of the case main body 132 and the cover part 134, and the caulking protrusion is inserted into the long sliding hole 136a. By inserting the portions 132c and 134c, the front cover 135 and the unit case 131 can be slid along the longitudinal direction of the front cover 135.

  The slider 136 is provided with a pair of linkage pins 137 and a rack 138. The linking pin 137 is a metal columnar member formed to have a size that can be fitted into the linking hole 122 of the locking bar 120, and the unit case 131 extends from one surface that is the same at both ends of the slider 136. Protrudes to the side. The rack 138 is a rectangular flat plate member having a plurality of rack teeth 138a formed linearly at the distal end side portion and a pair of caulking claw pieces 138b at the proximal end side portion. The rack 138 is slidably accommodated between the case main body 132 and the cover part 134 with the rack teeth 138 a formed on the front end side thereof engaged with the pinion 133, and the caulking claw piece 138 b is accommodated in the slider 136. The slider 136 is attached to the central portion in the longitudinal direction by caulking into the caulking hole 136b.

  In the operating mechanism 130 configured as described above, when the pinion 133 is rotated from the outside of the unit case 131, the rack 138 slides between the case main body 132 and the cover portion 134, and the slider is moved along with the sliding of the rack 138. 136 slides between the unit case 131 and the front cover 135 along its longitudinal direction. The sliding direction of the slider 136 is up and down corresponding to the rotation direction of the pinion 133. During this time, the slider 136 is in a state where the three sides are covered by the cover plate portion 135a and the pair of skirt portions 135b of the front cover 135, and the configuration is such that the slider 136 can be viewed from the outside as long as the pair of skirt portions 135b is not looked between. Absent.

  In order to attach the operating mechanism 130 to the left vertical rod 23a, the unit case 131 is inserted into the left vertical rod 23a from the mounting opening 26, and the linkage pin 137 is fitted in the linkage hole 122 of the locking bar 120. The cover mounting screw 139 is fastened to the mounting screw hole 27 of the left vertical rod 23a through a pair of mounting screw escape holes 135d formed in the front cover 135, and the operation handle 30 is further attached to the indoor-side finding surface 23a2 of the left vertical rod 23a. Can be attached.

  In this case, according to this fitting, since the unit case 131 is offset with respect to the front cover 135, if the direction of the operating mechanism 130 is upside down with respect to the mounting opening 26, the front cover 135 is bent to a pair. It cannot be inserted between the portions 25b. Thereby, there is no fear that the unit case 131 is attached upside down with respect to the left vertical rod 23a, and the unit case 131 is always arranged at a preset position with respect to the inner surface 23a3 of the left vertical rod 23a.

  Further, since the slider 136 is disposed outside the left vertical rod 23a, the operation of fitting the linkage pin 137 of the slider 136 into the linkage hole 122 of the locking bar 120 can also be performed outside the left vertical rod 23a. Thus, the assembling work of the lock device 100 can be carried out very easily.

  By the way, a pair of slide guides 25 are provided on the door-end surface 23a1 of the left vertical shaft 23a. For this reason, the mounting opening 26 cannot be provided unless the slide guide 25 is avoided. In other words, in the above-described left vertical gutter 23a, as shown in the cross section of FIG. 10-1, the opening position located on the indoor side of the mounting opening 26 is matched with the inner surface 23a3 of the left vertical gutter 23a. Cannot be provided and must be provided outside the inner surface 23a3 of the left vertical gutter 23a. When the unit case 131 is simply inserted into the mounting opening 26 with respect to the left vertical rod 23a, a gap is generated between the unit case 131 and the inner surface 23a3 of the left vertical rod 23a.

  Therefore, in this joinery, as shown in FIGS. 10-1 to 10-3, the liner member 140 is previously attached to the attachment port 26 of the left vertical rod 23a, and the inner surfaces of the unit case 131 and the left vertical rod 23a are installed. 23a3 is filled. As illustrated in FIG. 3A, the liner member 140 integrally includes a liner portion 140a having a substantially rectangular shape and a pair of engaging portions 140b that protrude in a direction away from both ends of the base end of the liner portion 140a. It is the metal member formed in. The liner portion 140a has a width slightly shorter than the length along the vertical direction of the mounting opening 26 formed in the left vertical rod 23a, and is formed by being appropriately bent in the out-of-plane direction. As shown in FIG. 4, when one surface 140a1 is brought into contact with the inner surface 23a3 of the left vertical shaft 23a, the other surface 140a2 is arranged on the opening edge extension located on the indoor side of the mounting opening 26. It is. This liner portion 140a has a notch 140c formed in a portion corresponding to the drive shaft insertion hole 28 formed in the indoor-side finding surface 23a2 of the left vertical shaft 23a, and in a portion corresponding to the pair of handle mounting holes 29. A handle screw insertion hole 140d is formed in each case. As shown in FIGS. 4-1 and FIGS. 10-1 to 10-3, the pair of engaging portions 140b are respectively attached to the door-end surface 23a1 of the left vertical rod 23a when the liner portion 140a is inserted into the mounting opening 26. The liner portion 140a is positioned and arranged inside the left vertical rod 23a. Specifically, when the liner portion 140a is inserted from the mounting opening 26 and the pair of engaging portions 140b are brought into contact with the door end surface 23a1, one surface 140a1 of the liner portion 140a is the inner surface 23a3 of the left vertical rod 23a. And the notch 140c and the pair of handle screw insertion holes 140d are disposed at the mounting positions facing the drive shaft insertion hole 28 and the pair of handle attachment holes 29, respectively.

  Accordingly, if the unit case 131 is inserted into the left vertical rod 23a from the mounting port 26 with the liner member 140 previously mounted in the mounting port 26, the liner member 140 causes the inner surface of the unit case 131 and the left vertical rod 23a to be inserted. The gap between 23a3 is filled. As a result, if the operating handle 30 is attached to the indoor-side finding surface 23a2 of the left vertical shaft 23a and the handle mounting screw 33 is screwed into the main body screw hole 132a from this state, the unit case 131 is not deformed. The operation handle 30 can be attached to the vertical rod 23a, and the unit case 131 can be attached to the inside of the left vertical rod 23a.

  In the lock device 100 to which the operation mechanism 130 is attached as described above, when the operation handle 30 is rotated, the pinion 133 fitted to the drive shaft 31 rotates, and the rack 138 meshed with the pinion 133 extends along the vertical direction. Thus, the slider 136 slides in the same direction in a moving space defined between the front cover 135 and the door front surface 23a1 of the left vertical port 23a. When the slider 136 slides, the locking bar 120 slides in conjunction with it, and the lock pin 121 moves up and down with respect to the left vertical rod 23a, and the lock receiving portion 110 (provided on the vertical frame 13a of the opening frame 10). 2), the engagement state and the disengagement state are switched. When the door 20 is engaged with the opening frame 10 in a closed state, the lock pin 121 abuts against the lock receiving portion 110, thereby restricting movement of the opening frame 10 in the direction in which the door 20 is opened. . On the other hand, when it is in the disengaged state, the lock pin 121 is disposed at a position retracted from the lock receiving portion 110 so that the shoji 20 can be opened to the outdoor side with respect to the opening frame 10. become.

  As described above, the operating mechanism 130 applied to the lock device 100 of the joinery includes the front cover 135. Moreover, when the operating mechanism 130 is attached to the left vertical rod 23a, the slider 136 is disposed between the front cover 135 and the door end surface 23a1 of the left vertical rod 23a. Therefore, even if the shoji 20 is opened with respect to the opening frame 10, the slider 136 is not exposed to the outside. As a result, there is no possibility of deteriorating the appearance quality of the joinery, and there is no possibility that foreign matters such as dust enter the operating power transmission unit such as the sliding part of the slider 136 and the engaging part of the rack 138 and the pinion 133.

  Here, the above-described front cover 135 has a U-shaped cross section in which a cover plate portion 135a and a pair of skirt portions 135b are integrally formed. Therefore, when the front cover 135 is attached to the left vertical rod 23a, the front cover 135 may be deformed if the fastening force of the cover attaching screw 139 is excessive.

  For this reason, in this joinery, as shown in FIGS. 6-8 and 10-3, the support part 150 is provided in the unit case 131, and this is attached to the door end surface 23a1 of the left vertical rod 23a and the cover plate of the front cover 135. It is made to interpose between the part 135a. The support portion 150 is formed on both the case main body 132 and the cover portion 134 constituting the unit case 131, and is a flat plate-like portion formed at a position adjacent to the respective caulking projections 132c and 134c. The support portion 150 is configured to have a width that allows insertion into the slide long hole 136a of the slider 136, and the door plate surface 23a1 of the left vertical rod 23a and the cover plate of the front cover 135 through the slide long hole 136a. It is interposed between the part 135a.
