Description

  The present invention relates to a sliding door strike that is attached to a vertical frame of an opening provided with a sliding door and is engaged with a hook lock protruding from the vertical hook of the sliding door, and in particular, a hook engaging metal fitting that engages with the hook lock. The present invention relates to an improved technology that can be adjusted in the sliding door opening / closing direction.

  For example, a locking device for a sliding door locks the sliding door so that it cannot be opened by protruding a hook lock from a lock body provided on the sliding door and engaging the hook lock with a sliding door strike plate provided on a vertical frame. There is something. Conventionally, a strike plate for sliding doors used in this type of locking device is generally composed of a troy having a recess recessed in a vertical frame, and a kama entrance hole that covers and engages the troy. It is comprised from the formed decorative board. Then, when the sliding door is closed and the vertical shaft of the sliding door comes into contact with the vertical frame of the opening frame, the hook lock protrudes from the lock body provided on the sliding door, and the hook lock enters the hook entrance hole of the strike plate for the sliding door. When the tip engages with the rear edge of the hook entry hole, it is locked to the sliding door strike plate and locks the sliding door so that it cannot be opened. When the sliding door is opened, the decorative plate to which the kama lock is engaged is exposed by the door contact surface of the vertical frame, so that the surface is finished with a mirror surface or a hairline.

  However, this type of sliding door strike plate has a structure in which the kama lock is engaged with the back edge of the kama entry hole formed in the decorative plate, and therefore, the engagement strength of the kama lock with the decorative plate. Both design and design are required, and it is difficult to satisfy both functions sufficiently. In other words, the decorative board is required to have high wear resistance and high strength against frequent engagement / disengagement, while it is required to have a mirror finish with an emphasis on design. . And, with a structure in which a kama lock is engaged with a kama entry hole formed in a simple plate-shaped decorative board, sufficient engagement strength cannot be obtained, and the kama lock is directly engaged with the decorative board. As a result of deterioration over time, the decorative board is distorted, rubbed, and the like, and the design properties are likely to be impaired.

  In addition, if the engagement portion is worn due to frequent engagement / disengagement, the entire decorative plate still having no problem in appearance has to be replaced, which imposes uneconomic maintenance. Further, in the structure in which the Kama lock is engaged with the plate-shaped decorative plate, the engagement portion between the Kama lock and the decorative plate is easily visually recognized, and there is a problem that it is difficult to ensure high crime prevention performance.

  There exists a strike board for sliding doors indicated by patent documents 1 as what solved such a malfunction. This strike door strike plate is a troyoke having a box-like recess recessed in a vertical frame, and a pair of legs are accommodated in the recess of the troyoke and bent into a substantially U shape at the pair of legs to be cross-linked. A hook engaging bracket whose protruding portion protrudes from the recess, and a pair of decorative plate fixing members inserted through the hook and the vertical frame are fixed to the vertical frame substantially flush with the hook engaging bracket. And a decorative board having a hook entry hole for allowing the hook lock protruding from the vertical hook of the sliding door to enter the recess. Do it.

  According to the strike plate for sliding doors, the troyoke, the hook engaging bracket, and the decorative plate are formed separately, the hook engaging bracket is accommodated in the concave portion of the troyoke, and the decorative plate is fixed together with the troyoke. It is attached to the vertical frame. Accordingly, each member can be manufactured with an optimal material or finish suitable for the use of the member.

For example, in the case of a hook engaging metal fitting, it can be manufactured from a material with high wear resistance and high strength against frequent engagement / disengagement with the hook lock. The mirror finish can be emphasized, and in the case of Troyoke, it can be manufactured using a general inexpensive material without the need to place importance on wear resistance and design. Then, the engagement portion with the kama lock is bent into a substantially U shape to increase the rigidity, and the engagement strength with the kama lock is increased as compared with the case where the engagement portion is simply engaged with the edge portion of the kama entry hole. Further, by removing the decorative plate, the hook engaging bracket can be detached, and the hook engaging bracket that has deteriorated over time due to the engagement with the hook lock can be easily replaced.

  However, in the conventional sliding door strike plate disclosed in Patent Document 1, a hook engaging metal fitting protruding from the decorative plate is attached in a fixed structure. That is, it did not have a mechanism for adjusting the sliding door opening / closing direction. The sliding door locking device provided with the sliding door strike plate has a structure in which the hook portion of the hook engaging metal fitting is sandwiched between the tip of the hook lock and the slider tip by swinging and rotating the hook lock from the lock mechanism side. It has become. Therefore, when the degree of engagement between each member changes due to dimensional error of each member or due to aging, a gap, so-called dust, is generated between the vertical frame and the sliding door, and the sliding door does not close properly with no gap when closed. did. This dust may become larger as the doorway in the sliding door opening / closing direction becomes larger. In addition, there has been a demand in terms of construction workability to make it possible to adjust the position where the hook lock is applied, that is, the engaging portion, eliminate the error, and make the chile as designed as possible. In addition, there is a demand for adjusting the degree of engagement in order to eliminate the looseness of the sliding door due to wind and vibration. In addition, when the degree of mutual engagement has changed due to aged wear, there has been a request to adjust during maintenance.

  The present invention has been made in view of the above situation, and provides a sliding door strike that enables adjustment of the hook engaging bracket in the sliding door opening / closing direction, thereby enabling adjustment of the chile dimension and realization of a reliable locking state. And it aims at improving the maintainability.

Next, the action of the sliding door strike configured as described above will be described.
FIG. 6 is a vertical cross-sectional view of the sliding door adjustable strike in which the hook engaging metal is in the retracted position, and FIG. 7 is a vertical cross sectional view of the sliding door adjustable strike in which the hook engaging metal is in the protruding position.
In the sliding door strike 100, when the operation portion 49a of the adjusting screw 49 exposed on the decorative plate 15 is rotated by the driver 55 or the like, the drive nut 51 screwed to the adjusting screw 49 is moved in the sliding door opening / closing direction. The side bracket 57 engaged with the drive nut 51 is moved up and down.

  When the side bracket 57 moves up and down, the hook engaging metal 13 engaged with the side bracket 57 is moved back and forth in the sliding door opening / closing direction. In other words, the hook engaging metal 13 can be moved forward and backward in the sliding door opening / closing direction via the side bracket 57 as the drive nut 51 moves.

  A side bracket 57 is interposed between the drive nut 51 and the hook engaging fitting 13, and a hook engaging gold is formed by two engagement structures of the drive nut 51 and the first inclined groove 59, the second inclined groove 63 and the pin 61. The tool 13 is indirectly driven. Thereby, compared with the case where the kama engagement metal fitting 13 is directly driven by the drive nut 51, the impact at the time of closing the sliding door becomes difficult to be transmitted to the drive nut 51, and the engaging portion 27 is held difficult to be displaced for a long time. It is like that.

  More specifically, when the adjustment screw 49 is rotated and the shafts 51a and 51a are moved along the lateral grooves 53, the side bracket 57 that engages the first inclined grooves 59 with the shafts 51a and 51a moves up and down. . When the side bracket 57 moves up and down, the hook engaging fitting 13 engaged with the second inclined groove 63 via the pin 61 is driven forward and backward in the sliding door opening / closing direction by movement along the elongated holes 65 and 65 of the pin 61. It will be. As shown in FIG. 6, when the drive nut 51 is moved forward and the side bracket 57 is lowered, the hook engaging metal 13 is protruded. On the contrary, as shown in FIG. 7, when the drive nut 51 is moved rearward and the side bracket 57 is raised, the hook engaging metal 13 is retracted.

  Since the inclination angle A of the second inclined groove 63 is formed to be steeper in the downward direction than the inclination angle B of the first inclined groove, the operating force on the adjustment screw 49 side is reduced, and the chile adjustment is performed. In addition to being easy, the impact strength on the side of the hook engaging metal 13 is increased, and the engaging portion 27 is difficult to displace. Further, since the second inclined groove 63 on the side of the hook engaging bracket 13 is steeply inclined, the distance in the sliding door opening / closing direction can be shortened, and accordingly, the troyoke 11, the side bracket 57, and the hook engaging bracket 13 can be reduced. The depth dimension (dimension in the sliding door opening / closing direction) can be formed shallow.

  Therefore, according to the sliding door strike 100 described above, the hook engaging metal 13 that is accommodated in the troyoke 11 and from which the engaging portion 27 protrudes, the decorative board 15 that is fixed to the vertical frame 21 and in which the hook entering hole 41 is formed, An operating portion 49a is exposed to the decorative plate 15, and an adjustment screw 49 in which the drive nut 51 is movably screwed, and is interposed between the drive nut 51 and the hook engaging metal 13, and is driven by the movement of the drive nut 51. Since the side bracket 57 for driving the hook engaging bracket 13 forward and backward in the sliding door opening / closing direction is provided, by rotating the adjusting screw 49 exposed on the decorative plate 15, the hook engaging bracket 13 is interposed via the side bracket 57. 13 can be adjusted in the sliding door opening and closing direction. As a result, it is possible to adjust the Chile size, realize a reliable locking state, and improve the maintainability.

  Thereby, even when the degree of mutual engagement is changed due to dimensional error of each member or due to aged wear, it is possible to adjust the dust that is a gap generated between the vertical frame 21 and the sliding door 17, and the sliding door 17 at the time of closing. Can solve the situation where does not close properly. In addition, in terms of construction workability, it is possible to adjust the position where the hook 25 is hooked, that is, the protruding dimension of the engaging portion 27, eliminate the error, and set the chile dimension as designed. In addition, it is possible to adjust the degree of engagement and eliminate rattling of the sliding door 17 due to wind and vibration.

  Further, a side bracket 57 is interposed between the drive nut 51 and the hook engaging fitting 13, and the hook is engaged by the engagement structure of the drive nut 51 and the first inclined groove 59, the second inclined groove 63 and the pin 61. Since the joint fitting 13 is indirectly driven, the impact at the time of closing the sliding door is less likely to be transmitted to the drive nut 51 as compared with the case where the kama engagement fitting 13 is directly driven by the drive nut 51, and the engagement is performed for a long time. The portion 27 can be held with little displacement. As a result, it is possible to prevent a decrease in appearance due to an increase in the size of dust.

  Further, since the second inclined groove 63 is formed with a steep slope in the downward direction with respect to the first inclined groove 59, the operation force on the adjustment screw 49 side can be reduced to facilitate the adjustment of the dust, and the hook engaging bracket. The impact strength on the 13th side can be increased to make it difficult to displace the engaging portion 27. Further, since the second inclined groove 63 on the side of the hook engaging bracket 13 is steeply inclined, the distance in the sliding door opening / closing direction can be shortened, and accordingly, the depth dimension of the troyoke 11, the side bracket 57, and the hook engaging bracket 13 (sliding door opening / closing). The overall dimension of the sliding door strike 100 can be reduced in size by reducing the direction dimension). On the contrary, the plate thickness can be set larger by the dimension, a highly rigid structure can be obtained, and durability, crime prevention and the like can be improved.

  In addition, the above-described sliding door strike 100 can prevent mischief such as the operation unit 49a not being exposed and being rotated by adding another decorative plate covering the adjustment screw 49.
