Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sliding door lock for joinery including a trigger and a sickle piece interlocking with the trigger.
[0002]
[Prior art]
Conventionally, this type of sliding door lock for a fitting has been projected from the front of the lock case toward the receiving metal fitting as described in each example of Japanese Utility Model Laid-Open No. 57-110260 and Japanese Patent Laid-Open No. 8-86132, for example. The trigger (horizontal protrusion) to be performed was quite long. The reason for this is that when the sliding door is closed, the trigger begins to retreat after the tip of the trigger hits the strike surface of the bracket, and the sickle piece rotates via the power conversion mechanism. If it is not “0”, the sickle piece could not be completely engaged with the strike. In other words, the sickle piece pivotally supported by the lock case completely protrudes when the sliding door “fits snugly (zero dust)” on the door frame.
[0003]
Therefore, the amount of protrusion of the trigger is reduced in order to eliminate the possibility of catching clothes as much as possible, and the trigger itself is reduced in size in relation to a plurality of members built in the case body of the lock case. It was not possible to achieve the tasks such as making the sickle piece fully project in the state of being attached, and attaching the sliding door lock corresponding to the selected dust to the sliding door.
[0004]
[Problems to be solved by the invention]
In view of the above-described conventional problems, the first object of the present invention is to reduce the protruding amount of the trigger. Thereby, size reduction of trigger itself can be achieved. The second purpose is that the strike-side push pin does not give a sense of incongruity in daily life and can eliminate any fear of catching clothes. The third purpose is that the trigger pushed by the strike-side push pin stably moves backward. The fourth object is that the sliding door lock corresponding to the selected dust can be attached to the sliding door only by exchanging the pushing pin for setting the dust on the receiving metal side.
[0005]
[Means for Solving the Problems]
The sliding door lock for joinery of the present invention includes a trigger that moves backward while being guided by the first horizontal guide portion of the lock case when it strikes when closing the sliding door, and a power conversion when the trigger moves backward into the lock case. In a sliding door lock for joinery comprising a sickle piece that rotates in a direction to engage with a strike through a mechanism, the power conversion mechanism includes a rack 26 formed on the trigger 21 and the rack 26 so as to mesh with the rack. The pinion 31 is formed on the base portion 33 of the sickle piece 30 that is pivotally supported, and the front of the strike fits within the frame of the sash as the door frame, and the front 11 of the lock case when the door is closed. than the front 11 enters into the lock casing to secure the mounting base end portion of predetermined length push pin 7, whereas, the trigger 21, when Hirakito, by the spring force of the trigger spring 24 The case 10 includes a short rod-shaped tip 22 that slightly protrudes from the front 11 of the case 10 and a horizontally long flange 23 that is connected to the protruding tip 22, and the trigger 21 is engaged with the horizontally long flange 23. When the sliding door is closed with the projection 25, the trigger 21 moves backward via the engagement projection 25 and the first horizontal guide portion 18 when the tip 22 hits the push pin. And
[0006]
In the above configuration, there are at least two types of push-in pins 7A corresponding to the setting of dust on the receiving metal side .
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described with reference to the first embodiment shown in FIGS.
[0008]
(1) Environment for Implementing the Invention and Main Members First, the environment for implementing the invention will be described with reference to FIG. X is an engraving type housed in the sliding door 1 or an imposition type sliding door lock fixedly attached to the sliding door surface. On the other hand, Y is a receiving fixture fixedly attached to the door frame 2, and this receiving fixture Y is composed of a troyoke 3 having a box portion and a strike (receiving seat) 4 superimposed on the opening of the troying 3. Become. The strike 4 is formed in a vertically long plate shape, and is fixed to the ear-shaped attachment portion of the troyoke 3 via a plurality of fixing means 5.
[0009]
By the way, in this embodiment, a horizontal push pin 7 (main member) is fixedly projected at an appropriate portion of the strike 4 near the longitudinal window 6. In this embodiment, the push-in pin 7 is fixed by caulking to the upper wall 4a of the strike 4 so as to be directed to the tip of the trigger. Therefore, the strike 4 moves the trigger backward via the push pin 7 when the sliding door 1 is closed.
[0010]
The push pin 7 has such a length that it does not give a sense of incongruity in daily life and does not get in the way. For example, FIG. 5 shows a case where the door frame 2 is a sash frame. In such a case, the length of the push-in pin 7 is set to be within the sash frame.
[0011]
(2) Lock Case Next, the lock case will be described with reference to FIG. Reference numeral 10 denotes a lock case that is installed in the vertical wall of the sliding door 1. The lock case 10 includes a “frame-shaped case body 10a” and a “plate-shaped case lid 10b” that closes a large opening of the case body. The lock case 10 is also part of the sliding door lock X. Reference numeral 11 denotes a front fixed to the opening on the front side of the lock case 10. The front 11 is generally fixed to a long plate-like cover plate (or front wall) 12 of the lock case 10 in general. Reference numeral 13 denotes a second fixing means for fixing the lock case to the sliding door 1. 14 is an entrance / exit window for sickle pieces, and 15 is a trigger window provided above the entrance / exit window 14 for sickle pieces. Here, main structural requirements respectively formed on the case body 10a and the case lid 10b constituting the lock case 10 will be described. In addition, the part which is not related to the specific requirements of this invention is omitted.
[0012]
Referring to FIG. 2, reference numeral 16 denotes a spring support portion fixed so as to protrude from the rear wall 17 of the case body 10 a to support the trigger spring, and 18 and 18 denote the case body 10 a orthogonal to the rear wall 17. The trigger horizontal guide portion is formed so as to face the wall surface of the case lid 10b (which corresponds to the front and rear side walls). These horizontal guide portions (first horizontal guide portions) 18 and 18 are horizontal guide long holes in this embodiment. The horizontal guide portions 18 and 18 are formed in the lock case 10 along the horizontal line of the spring support portion 16. 19 is a sickle support shaft shaft hole formed at the center of the lock case 10 (both case body 10a and case lid 10b), and 20 is not directly related to the structural requirements of the present invention. It is the vertical window for the formed operation piece.
[0013]
(3) Trigger: Advance / Retreat Member Next, the trigger will be described with reference to FIGS. Reference numeral 21 denotes a trigger (advancing / retracting member) slidably mounted in the lock case 10. The trigger 21 includes a short hook-shaped tip 22 that protrudes from the front 11 of the lock case 10 when the door is opened, and a horizontally long hook 23 that is connected to the protruding tip 22 so as to be slightly wider.
[0014]
A trigger spring 24 is incorporated in the lateral direction between the rear end face of the horizontally long flange 23 and the rear wall 17 of the case body 10a. The trigger spring 24 has a distal end pressed against the rear end face of the horizontally long flange 23, while the rear end is supported by the spring support 16. Therefore, when the sliding door 1 is opened, the trigger 21 is urged so that a part of the tip portion 22 always protrudes from the front 11.
[0015]
By the way, as described above, in this embodiment, the push pin 7 protrudes from the front surface of the strike 4. Therefore, when the sliding door 1 is closed, the trigger 21 is directly pushed by the push pin 7 and is inside the lock case 10. Move backwards. Depending on the size of the “Chile” set between the door frame 2 having the metal fitting Y and the sliding door 1 having the sliding door lock X, for example, 1 mm, 3 mm, 5 mm, etc., for example, as shown in FIG. When the dust is about 1 mm, the push-in pin 7 enters the trigger window 15 so that the trigger 21 enters the lock case 10 against the spring force of the trigger spring 24. Yes.
[0016]
When the trigger 21 moves backward in the lock case, the trigger 21 is guided to the horizontal guide portions 18 and 18 of the lock case 10. At this time, the trigger 21 needs to be guided “smoothly” without rattling. Therefore, in the present embodiment, projecting piece-like engagement projections 25 that are respectively engaged with the horizontal guide portions 18 and 18 of the lock case 10 are provided on both side walls of the horizontally long flange portion of the trigger 21. As shown in FIG. 4, the engagement protrusion 25 has a slightly feather shape (horizontal shape).
[0017]
Therefore, the trigger 21 smoothly moves forward and backward through the water-portion flat guides 18 and 18 of the lock case and the wing-like engagement portions 25 and 25 of the trigger, although having a very simple form.
[0018]
Reference numeral 26 denotes a part (a rack in this embodiment) of the power conversion mechanism formed on the lower side wall of the trigger 21.
[0019]
(4) Trigger spring The trigger spring 24 described above starts to contract as the trigger 21 moves backward when the tip 22 of the trigger 21 hits the pushing pin 7 of the strike 4 when the sliding door 1 is closed. On the other hand, as the sliding door 1 is opened, the distal end portion 22 extends away from the push pin 7 and extends as the trigger 21 advances. However, in this embodiment, as shown in FIG. 1, the protrusion amount of the tip 22 of the trigger 21 is small by an amount corresponding to the protrusion amount b (dimension between the phantom lines) of the push pin 7, so that the trigger 21 has a horizontally long shape. When the collar 23 hits the inner wall surface of the front 11, the amount of protrusion is considerably smaller than the amount of protrusion of the conventional trigger. Therefore, in the present embodiment, the tip portion 22 of the trigger 21 is expressed as “short hook shape”.
[0020]
(5) sickle piece 30 is a sickle piece. The sickle piece 30 is provided with a part (pinion) 31 of a power conversion mechanism at the base, and is pivotally supported in the lock case 10 via a sickle piece support shaft 32, and in conjunction with the backward movement of the trigger 21. Rotate in what way to strike 4 strike. Thus, the sickle piece 30 includes a base portion 33 having a pinion 31, a hook-shaped tip portion 34 that engages with the strike 4, and a wide rear end portion 35.
[0021]
1 shows the state of the push pin 7 and the trigger 21 in the open door state. In this case, (1) the short rod-shaped tip portion 22 of the trigger 21 slightly protrudes from the front 11 by the spring force of the trigger spring 24, and (2) the sickle piece 30 is rotated and retracted toward the lock case 10 side. .
[0022]
4 and 5 show the state of the sliding door lock X at the moment of closing. In this case, (A) the tip 22 of the trigger 21 is deeply inserted into the lock case 10 by the push pin 7 of the strike 4. At this time, the trigger 21 as a whole moves backward in the lock case 10 against the spring force of the trigger spring 24. (B) The sickle piece 40 rotates and advances in conjunction with the retreat of the trigger 21, and the hook-shaped tip 34 is engaged with the strike 4. At this time, the sickle piece 30 rotates around the support shaft 32 via the power conversion mechanisms 26 and 31 to be in a so-called engagement state, but in this embodiment, even if the “Chile dimension is not O”, Even if the set dust is 1 mm, 3 mm, or 5 mm ”, the sickle piece 30 protrudes completely and its tip 34 is engaged with the strike 4.
[0023]
【Example】
This column shows the second embodiment shown in FIGS. 6 to 9 and other examples of the main members shown in FIG. In the following description of the second embodiment, the same parts as those in the first embodiment are denoted by the same or similar reference numerals, and redundant description is omitted.
[0024]
The second embodiment is mainly different from the first embodiment in the configuration of the trigger 21A. That is, the trigger 21A is a trigger main body having a short rod-shaped tip portion 22 that slightly protrudes from the front 11 by the spring force of the trigger spring 24 and a laterally long flange portion 23 that is slightly wider than this when opened. 40 and, for example, a slide guide long plate 41 extending perpendicularly to one side wall 40a of the trigger body 40 so as to face the wide side wall 37 of the case body 10a. A cutout 45 for receiving the spindle 32 of the sickle piece is formed at the upper end of the slide guide long plate 41 in the horizontal direction.
Further, a second horizontal guide portion 43 with which a plurality of slide engagement pins 42 and 42 projecting from the slide guide long plate 41 are respectively engaged with a portion near the lower portion of the case lid 10b constituting the lock case 10A. Is formed.
[0025]
The second horizontal guide portion 43 is a horizontal guide slot in the present embodiment, like the trigger horizontal guide portion 18, but the lower second horizontal guide portion 43 is the trigger horizontal slot. Longer than 18. Further, the slide guide long plate 41 can come into contact with the inner wall surface of the front wall (front or long plate-like lid plate) 12 of the lock case 10 </ b> A when the door is opened, It has the function of a stopper that projects only a small amount.
[0026]
In the above configuration, the operation and effect are the same as those of the first embodiment. However, in the case of the second embodiment, when the trigger 21A moves forward and backward, the engagement protrusions 25 and 25 guided by the first horizontal guide portions 18 and 18 provided on the upper side of the lock case 10A, and the lock case 10A. Since the guides are respectively guided by the slide engagement pins 42 of the second horizontal guide portion 43 provided on the lower side of the trigger 21A, there is an advantage that the trigger 21A moves backward more stably.
[0027]
Next, another example of the main member shown in FIG. 10 will be described. Reference numeral 7A denotes a replaceable push-in pin having a male screw portion 50 and a flange portion 51 which are screwed into the female screw portion 8 formed on the upper wall 4a of the strike 4A. This push-in pin 7A is used for setting the dust, and can be exchanged depending on the distance between the “chilli” to be set as described above, for example, 1 mm, 3 mm, or 5 mm. That is, at least two types of push pins 7A having different length dimensions are prepared.
[0028]
Therefore, in the push pin 7A of this other example, a desired dust can be obtained simply by exchanging the push pin 7A on the receiving metal Y side. Therefore, the sliding door lock X corresponding to the selected dust is attached to the sliding door 1. Can be attached.
[0029]
In each embodiment of the present invention, the shape of the tip surface of the push-in pins 7 and 7A is not particularly limited, such as a circular shape, an elliptical shape, a track shape, and a rectangular shape.
[0030]
【The invention's effect】
As is clear from the above description, the protrusion amount of the trigger can be reduced in the present invention. As a result, the tree itself can be reduced in size. Also, the strike side push pin does not give a sense of incongruity in daily life and does not get in the way (there is less risk of catching clothes). Further, the trigger pushed by the strike side push pin stably moves backward. Furthermore, there is an effect that the sliding door lock corresponding to the selected dust can be attached to the sliding door only by exchanging the pushing pin for setting the dust on the receiving metal side.
