Description

  The present invention relates to a seat for a sickle lock that is embedded in a pillar or a vertical frame of a sliding door and engages with a hook of the sickle lock when the sliding door is closed.

  Conventionally, sickle locks have been widely used as simple locking means for connecting the sliding door end surface and the pillar or vertical frame in contact with each other.

  A general sickle lock consists of a sickle lock body embedded in a mounting hole carved in the end face of a sliding door and the like, and a bowl-shaped seat embedded in a mounting hole carved in a pillar or vertical frame. The hook of the main body is rotated by a lever handle or the like and engaged with an opening provided on the front plate of the seat, and the hook is locked by being hooked on the back surface of the front plate.

  By the way, when locking such a sickle lock, it is possible to lock the tip key portion of the hook engaged with the opening of the front plate in a state of being in close contact with the back surface of the front plate. Preferred for. However, if the hooking stroke is excessive due to the assembly error or mounting error of the sickle lock after the installation of the sliding door, the hook does not come into contact with the back of the front plate, or the hook is tightly hooked. There is a problem that it is not securely locked.

  In particular, if a gap occurs between the sliding door end surface and the contact surface of the pillar or vertical frame due to an error in the front-rear direction of the hook (width direction of the sliding door), in addition to the ease of use, a thin plate is inserted into the gap. This makes it easy to remove the hooks, and causes problems with crime prevention.

  Therefore, as means for solving the problem caused by back and forth rattling, the applicants of the present application disclosed in Japanese Patent Application Laid-Open No. 9-112086 in that the upper piece is hooked under the opening on the back surface of the front plate in the seat. A "U" shaped locking member as a locking part is rotatably arranged at the bent part, the lower piece of the locking part is urged by the spring against the back of the front plate, and the locking part is attached to the spring. As a force biased inward, a means for avoiding rattling with a biasing force acting on the locking portion without adjusting the distance between the hook and the locking portion has been proposed.

  However, this seat does not need to be adjusted due to the error in the longitudinal direction of the sickle lock, but when the biasing force of the spring in the seat is weakened, the locking portion on which the hook is hooked easily turns. Too much, it becomes easier to create a gap between the sliding door and the vertical frame at the time of locking, and on the contrary, if the spring biasing force is set too strong, the resistance when hooking is increased and the locking operability by the hook is deteriorated, Has the disadvantages.

  In addition, this seat can eliminate the error in the front-rear direction, but the error in the up-down direction cannot be resolved. In the case where a gap is generated between the lower surface of the part and the locking part, there arises a problem that the hook is easily detached in addition to the possibility of rattling.

  In order to solve this problem, Japanese Patent Application Laid-Open No. 2004-124383 presents an adjustment screw that adjusts the vertical position of the sliding door in addition to an adjustment screw that adjusts the position of the sliding door in the front-rear direction. Japanese Patent Laid-Open No. 2001-82005 presents means that enables adjustment in the front and rear and up and down directions by providing a slide frame body that can be adjusted up and down and an adjustment frame body that can be adjusted in the front and back directions in the seat. ing.

  By these means, it is possible to adjust not only the error before and after the sliding door or sickle lock but also the vertical error. However, even with such a technique, errors that occur in the thickness direction of the sliding door cannot be eliminated. That is, when there is no play between the thickness of the hook and the opening of the front plate or the width of the locking portion, the sliding door is closed when an error in the thickness direction occurs in the hook of the sliding door or sickle lock itself. Occasionally, they may collide and become unable to engage the hook. Therefore, since all the sickle locks are provided with a predetermined play between the hook width and the width of the opening or the locking portion assuming a slight error in the thickness direction, there is a backlash in the thickness direction during locking. Is likely to occur.

In addition, the seat of the sickle lock provided with the plurality of adjusting means is complicated in structure, and the manufacturing cost is likely to increase, and the durability of the adjusting means and the locking portion having an elaborate structure is likely to be a problem. .
Japanese Patent Laid-Open No. 9-112086 JP 2004-124383 A Japanese Patent Laid-Open No. 2001-82005

  The present invention is intended to solve the above-described problems. The seat of the sickle lock provided on the sliding door is excellent in durability at a low cost with a simple structure, and is provided in the front-rear direction and the up-down direction. It is an object of the present invention to eliminate backlash in the thickness direction of the sliding door in addition to eliminating backlash due to direction errors.

  Therefore, the present invention has a front plate opening portion of the seat that has a wide end portion on the upper end side, a tapered portion that continuously decreases from the lower end thereof, and a width that decreases downward, and a hook that is hooked on the lower end thereof. As a seat for a sliding door sickle lock, the slide body has a vertical adjustment slit that is narrower than the wide portion where the slide body having a locking portion is slidably arranged up and down. On the outer surface of the front plate on the adjustment slit, the vertical adjustment screw penetrates from the outside, passes through the vertical adjustment slit, and is screwed into the screw hole of the fixing plate arranged on the back side of the front plate, and the vertical adjustment screw is loosened. The vertical position can be adjusted, and the locking part is fixed to the back side with the front plate sandwiched by the front and rear adjustment screws that penetrated from the outside of the slide body, and the hook end of the hook contacts It has a vertical contact surface that can be It was assumed a depth from the front plate of the contact surface and is adjustable by turning the front and rear adjusting screw from.

  The simple structure of the seat of the sickle lock makes it possible to keep the manufacturing cost low, and it is possible to make adjustments in the front-rear direction by simply turning the front-rear adjustment screw from the outside of the seat using a screwdriver. Thus, the vertical adjustment can be performed by loosening the vertical adjustment screw. In addition to this, a slit portion that reduces the width is provided below the wide portion where the hook first engages in the opening, so that when the wide portion is wider than the hook thickness by a predetermined width, the hook is It is easy and reliable to engage from the opening, and the hook enters the lower adjustment side of the taper part which is narrower than the wide part and has little play at the time of hook entry in the locked state or the vertical adjustment slit that follows this. Thus, the backlash in the thickness direction of the sliding door can be limited.

  In addition, the slide body is provided with a folded portion whose upper end side is inserted through the vertical adjustment slit and folded inside, and the folded portion is narrower than the vertical adjustment slit and the neck portion and the vertical adjustment slit are inserted therethrough. If it is wider and has a holding part that abuts the inner surface of the front plate at the inner surface of both ends and sandwiches the front plate, and restricts the horizontal movement of the slide body, the hook hook state is stable The backlash is further reduced, and there is no fear that the slide body will fall off when the vertical adjustment screw is loosened in the vertical adjustment, and the adjustment becomes extremely easy.

  Further, if the hook part of the slide body is locked, the lower surface of the arm part of the hook comes into contact with the upper surface of the neck part, and if the hook is supported together with the latching part in the locked state, the hook locking pressure is dispersed. Therefore, it can be made extremely excellent in durability.

  According to the present invention, the seat of the sickle lock can be simply configured to achieve cost reduction and excellent durability. In addition, by providing the opening with a tapered portion and a vertical adjustment slit that follows this, in addition to eliminating errors in the front and rear and up and down directions, it is also possible to eliminate rattling that occurs in the thickness direction of the sliding door. .

  The embodiment of the present invention will be described with reference to the drawings. FIGS. 1 to 4 show a sickle lock seat 1 according to the present embodiment. 1A is a front view of the receiving seat 1, FIG. 1B is a sectional view taken along line XX in FIG. 1A, and FIG. 1C is a sectional view taken along line YY in FIG. It is. The receiving seat 1 has a housing 13 embedded in a mounting hole carved at a position corresponding to the sliding door-side sickle lock main body on the surface with which a vertical frame or a column sliding door (not shown) abuts, and covers the opening surface of the metal A substantially rectangular front plate 10 made of a material is fixed with screws 30c and 30d.

  The opening 11 of the front plate 10 is cut out vertically in accordance with the hook orbit to be engaged, a rectangular wide portion 11a from the top, followed by a tapered portion 11b that shrinks downward, followed by this. It consists of a vertically elongated slit 11c. The wide portion 11a is wider than the hook thickness (width) of the sickle lock body that passes through and engages with the wide portion 11a, but generally the thickness of the sliding door is set to be twice or more the hook thickness. Even if there is some error in the vertical direction, the hook is surely easily engaged.

  The taper portion 11b that continues to the lower end side of the wide portion 11a and shrinks downward is an upper portion of the vertical adjustment slit 11c that is narrower than the wide portion 11a and slightly wider than the hook hooked at the lower end side. Communicate with the side. Thus, by providing the taper date 11b between the wide portion 11a and the vertical adjustment slit 11c, even if there is an error in the thickness direction of the sliding door on the hook entering from the wide portion 11a, the arm portion is It can be smoothly guided to enter the lower end of the tapered portion 11b or the vertical adjustment slit 11c.

  The vertical adjustment slit 11c is composed of an upper hook entry portion 111 and an adjustment screw sliding portion 112 which is continuous to the lower end of the hook through a stepped portion and narrower than this, and the slide body 20 is formed on the outer surface of the upper front plate 10. It is provided so as to be slidable up and down and is fixed at a predetermined height. Further, in the vicinity of the edge of the opening 11 of the front plate 10, the slide body 20 is placed flush with the outer surface of the front plate 10 from the middle of the tapered portion 11b to the lower side of the vertical adjustment slit 11c. A slide recess 15 that is wider and vertically longer than the slide body 20 is formed.

  Referring to the exploded perspective view of FIG. 2, the slide body 20 includes a main body 21 made of a thin metal plate having a trunk portion 21 a and a folded portion 21 b that has its upper portion folded inward, and a front and rear adjustment screw on the back side thereof. The locking portion 22 is fixed by 30a, and the fixing plate 23 is fixed by the vertical adjustment screw 30b.

  The body 21a of the main body 21 is made of a metal plate having a rectangular upper part and a semicircular lower part, and has two fixing holes 210 and 211 arranged in the vertical direction. The adjusting screw 30b penetrates from the outside. Then, the folded portion 21b folded inward at the upper portion thereof passes through this in the horizontal direction with the neck portion 212 slightly narrower than the slit width of the hook entry portion 111 of the vertical adjustment slit 11c and bends downward and hooks downward. The inner surface of both ends of the holding portion 213 that is wider than the entry portion 111 is in contact with the inner surface of the front plate 10 so as to be sandwiched therebetween. In addition, since the width | variety of this holding | suppressing part 213 is a little narrower than the wide part 11a, the slide body 20 is made to slide forward by inserting the front end side of the folded part 21b into the wide part 11a and sliding it downward. It can be attached to the plate 10.

  Further, on the back side of the slide body 20 mounted on the front plate 10, a locking portion 22 made of a metal and rectangular plate material bent in a U-shape in plan view is projected on the outer surface of the central portion. It is fixed by screwing a front / rear adjustment screw 30a into a columnar leg portion 22a having a screw hole. The locking portion 22 has a lateral width that is substantially the same width that is slightly smaller than the inner width of the housing 13, and is limited in movement in the width direction within the housing 13. The hook is protruded from the lock main body and is engaged with the inner side surface of the hook end of the hook so as to be brought into contact with the vertical contact surface 22b. By rotating the front / rear adjustment screw 30a, the front surface of the contact surface 22b is rotated. The depth from the plate 10 can be adjusted.

  In addition, a fixing plate 23 made of a rectangular metal plate having a width wider than the slit width of the adjustment screw sliding portion 112 is provided on the back side of the slide body 20 below the locking portion 22. The adjustment screw 30b is screwed in, and the front plate 10 is sandwiched between the inner surface thereof and the back surface of the body portion 21a of the slide body 20, so that the slide body 20 is fixed to a predetermined height on the front plate 10. ing. Further, by loosening the vertical adjustment screw 30b, the slide body 20 can be slid up and down, and the height of the locking portion 22 can be freely changed within a predetermined range.

  Next, the effect | action of the seat 1 of the sickle lock of this Embodiment is demonstrated using FIG. 3 and FIG.

  FIG. 3 shows a state in which the hook 51 of the sickle-shaped main body 50 on the sliding door side indicated by a one-dot chain line is engaged with the seat 1 and locked. At this time, the hook 51 has no error in the front / rear / left / right positions, the lower surface of the arm 51a is in horizontal contact with the upper surface of the neck 212 and the upper end of the contact surface 22b, and the inner surface of the tip collar 51b is the locking portion 22. The contact surface 22b is in close contact with each other, the latching state is stable, and the sliding door is not rattled. Even if there is a slight error in the thickness direction of the sliding door, the hook 51 is guided by the tapered portion 11b of the opening portion 11 and smoothly enters the hook entry portion 111 that is slightly wider than the width of the hook 51 of the vertical adjustment slit 11c. The door enters and stops, and the play in the thickness direction of the sliding door is limited.

  On the other hand, FIG. 4A shows that the hook 51 is displaced in the vertical direction and the front-rear direction due to a position error at the time of sickle mounting or an error caused by deformation after the mounting. A case is shown in which a gap is generated between the engaging portion 22 and the back and forth and the left and right are likely to be rattled.

  In this case, as shown in FIG. 4B, the vertical adjustment screw 30b is temporarily loosened to slide the slide body 20 upward, and the lower surface of the arm portion 51a of the hook 51 is connected to the upper surface of the neck portion 212 of the slide body 20 and the engagement. The vertical adjustment screw 30b is tightened and moved to a position where it abuts on the upper end of the contact surface 22b of the portion 22, and then fixed, and the front / rear adjustment screw 30a is turned to turn the inner surface of the tip flange 51b of the hook 51 to the contact surface 22b. The locking part 20 is moved in the back direction and fixed until it comes into contact with the snugly.

  In this way, by the extremely simple procedure, errors in the vertical and forward / backward directions of the hook 51 at the time of locking can be eliminated, and rattling can be easily eliminated. Since the front plate 10 is always sandwiched between the pressing portions 213 of the slide body 20, the slide body 20 will not swing back and forth or fall off even when the vertical fixing screw 30b is loosened. Is extremely easy. Further, in the locked state, the hook 51 is supported not only on the locking portion 22 but also on the upper surface of the neck portion 212 of the slide body 20, so that the hooked state is stabilized and the rigidity of the contact portion of the hook 51 is high. It becomes extremely excellent in durability.
