Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hooking mechanism for a sickle piece of a sliding door lock.
[0002]
[Prior art]
When the sliding door 1 is closed, the so-called “backlash” may occur. This looseness is caused by the inclination of the door frame and the sliding door. As one means for eliminating such backlash, for example, a vertical guide engaging portion is formed on the opposite side wall of the strike, and a kama catcher is vertically fitted in the vertical guide engaging portion, and a spring member Thus, a configuration in which the hook catcher is always urged in the engagement direction of the sickle piece is conceivable.
[0003]
However, in the above configuration, even if the sliding door is closed and the hook catcher receives the tip of the sickle piece, if the hook is pulled in the opening direction, the hook catcher is free by the spring force of the spring member. Since it moves (for example, rises), it is difficult to reduce the “backlash” in the sliding door opening direction. Based on this background, the current, in the state of sickle piece full engagement upon閉戸, reducing extreme force to "play" in the opening direction of the sliding door is desired.
[0004]
[Problems to be solved by the invention]
In view of the conventional demands, the first object of the present invention is to minimize the “backlash” in the sliding door opening direction in the state where the sickle piece is completely engaged when the door is closed. The second object is to achieve the object of the first item by combining the members reasonably and reducing the number of parts. The third object is that when the sickle piece is unlocked, the claw-like engaging portion of the movable capturing member is engaged with the engaged portion of the engagement receiving plate, which causes the sickle piece to be locked when the sickle piece is locked. Inconveniences (bad effects) that cannot be completely removed will not occur.
[0005]
[Means for Solving the Problems]
The hooking mechanism for sickle pieces of the sliding door lock according to the present invention is provided at the distal end portion 6 of the sickle piece 1 and is supported by the support spring 15 provided in the strike body 11 and suspended in a suspended state by the support spring 15. and with the sickle piece movable catching member 17 for adsorbing via a magnetic force of a magnetic material or a magnetic body provided in the sickle piece movable catching member 17, in the state of sickle piece full engagement upon閉戸, the sliding door 2 An engagement receiving plate 30 fixed to the back surface of the strike receiving plate 12 so that the movable capturing member 17 that has captured the distal end portion 6 of the sickle piece 1 can be locked when pulled in the opening direction.

[0007]
DETAILED DESCRIPTION OF THE INVENTION
An example based on the embodiment of the present invention will be described with reference to FIGS. 1 is a sickle piece of a sliding door lock. Since the internal locking mechanism of the sliding door lock is not a specific requirement of the present invention, illustration and description thereof are omitted. The sliding door lock is generally attached to the downside of the open side end of the sliding door 2 in general. A stainless steel sickle piece 1 that adsorbs a magnetic body is supported by a fixed shaft 5 that is horizontally mounted on a lock case 4 having a front 3. And each site | part of the sickle piece 1 can be generally divided into the bowl-shaped front-end | tip part 6, the neck part 7 connected to this, and the wide rear-end part 8. In this embodiment, an inclined suction surface 9 is formed on the bowl-shaped tip 6.
[0008]
On the other hand, Y is a strike attached to the door frame 10, and this strike Y is composed of a case-like strike body 11 and a receiving plate 12 attached to an opening of the strike body 11. The receiving plate 12 has a receiving hole 13 into which the front end portion 6 of the sickle piece 1 enters while facing the front 3 when the door is closed. The sickle piece hooking mechanism X of the present invention is housed in a strike Y that is a receiving member of the sickle piece 1. Hereinafter, the specific structural member which comprises the hooking mechanism X for sickle pieces is demonstrated.
[0009]
First, reference numeral 15 denotes a support spring for the movable capturing member, and the central portion of the support spring 15 is attached to a spring mounting shaft 16 that is horizontally mounted on the side wall of the strike body 11. In this embodiment, the support spring 15 is a torsion spring, and its one end 15 a is in contact with or pressed against the vertical wall 11 a on the back side of the strike body 11, while the other end 15 b is fixed to the movable capturing member 17. It is attached to a horizontal support shaft 18 provided in a wound state.
[0010]
Reference numeral 17 denotes a sickle-piece movable capturing member suspended from the other end 15 b of the support spring 15. Since the movable capturing member 17 is supported in a suspended state by the support spring 15 via the horizontal support shaft 18, the movable capturing member 17 can move on its concentric circle with the spring mounting shaft 16 as a center. “The term of the movable capture member 17” means that even when the sickle piece 1 that is engaged when the door is closed moves slightly according to the movement of the door, the sickle piece 1 is caught and engaged with the engagement receiving plate. Used for convenience. Therefore, the meaning is the same even if the movable capturing member 17 is referred to as a “kama catcher”.
[0011]
The movable capturing member 17 of the present embodiment includes a case main body 21 having an upper end opening, and a first magnetic body (permanent magnet) 23 fixed to at least an upper side of a front wall (engagement receiving side) 22 of the case main body 21. On the other hand, the second magnetic body 25 fixed to the inclined rear wall (on the strike wall vertical wall 11a side) 24 of the case body 21, and the triangular opposing side walls (corresponding to the left and right side walls) 26 of the case body 21; 26 includes a horizontal support shaft 18 that is horizontally mounted on a portion near the upper end portion of 26, and a claw-like engagement portion 27 that protrudes from a lower portion of the front wall 22 (including an appropriate portion closer to the lower portion). The claw-like engaging portion 27 protrudes in the horizontal direction so as to be able to engage with a plurality of engaged portions 31 of a vertically long engaging receiving plate 30 fixed to the back surface of the receiving plate 12. Yes.
[0012]
Next, the engagement receiving plate 30 will be described. The engagement receiving plate 30 is appropriately fixed on the back surface of the receiving plate 12 in consideration of the positions of the distal end portion 6 of the sickle piece 1 and the movable capturing member 17 entering from the receiving hole 13 of the strike Y. The plurality of engaged portions 31 are rectangular horizontal long holes in this embodiment, and are arranged in parallel at a predetermined interval in the vertical direction. The engaged portion 31 may be a washing plate-like engagement groove. The upper edge portion forming the horizontal long hole 31 exhibits a locking function.
[0013]
Thus, in the present embodiment, the engagement receiving plate 30 is a magnetic body that repels in accordance with the polarity of the first magnetic body 23 of the movable capturing member 17. For example, if the first magnetic body 23 of the movable capturing member 17 is “N pole”, the condition is “N pole” (same polarity).
[0014]
Next, the operation will be described. FIG. 2 shows a case where the sliding door lock is in an unlocked state. In this case, the sickle piece 1 is retracted into the lock case 4. In the movable capturing member 17, the first magnetic body 23 and the engagement receiving plate 30 repel each other with the same polarity, so that the claw-like engaging portion 27 is disengaged from the engagement hole 31 of the engagement receiving plate 30. is seperated.
[0015]
FIG. 1 is an explanatory view when the sliding door 2 is closed and the sickle piece 1 is rotated about the fixed shaft 5 and enters the strike Y from the receiving hole 13 to be engaged. At this time, the sickle piece 1 is trapped by the distal end portion 6 of the sickle piece 1 and the second magnetic body 25 of the movable capturing member 17. That is, the attracting surface 9 of the sickle piece 1 is attracted to the second magnetic body 25 of the movable capturing member 17. At this time, depending on the position of the sickle piece, it is assumed here that the movable catching member 17 is slightly moved (tilted) in order to catch the tip portion 6 of the sickle piece 1. Therefore, in such a case, the claw-like engagement portion 27 is still separated from the engagement hole 31 of the engagement receiving plate 30 as in FIG.
[0016]
In FIG. 6, when the sliding door 2 is to be opened in the direction of arrow A (when the sliding door is slightly moved), the movable capture member 17 moves toward the engagement receiving plate 30 by the movement of the sickle piece 1, As a result, a state in which the claw-like engaging portion 27 is engaged with the engaged portion 31 of the engagement receiving plate 30 is shown. As is apparent from FIG. 6, even if the sliding door 2 is opened in the direction of arrow A, the movable capturing member 17 engages with the engagement receiving plate 30 in a state where the distal end portion 6 of the sickle piece 1 is captured. Opening (back) is regulated.
[0017]
【Example】
In the embodiment, the movable capturing member 17 is formed on the case body 21, and the magnetic body 23 repelling corresponding to the polarity of the engagement receiving plate 30 is fixed to the front wall 22 of the case body. In this case, the magnetic body 23 itself may be used as the front wall without providing the front wall 22.
The same applies to the case of the second magnetic body fixed to the rear wall of the case body 21.
[0018]
By the way, desirably, the engagement receiving plate 30 is a magnetic body, while the case main body 21 of the movable capturing member 17 has a magnetic body 23 that repels in accordance with the polarity of the engagement receiving plate 30. The reason is that if the sickle piece 1 is in an unlocked state and the claw-like engaging portion of the movable capturing member 17 is engaged with the engaging hole or the engaging groove of the non-magnetic engaging receiving plate at any moment. This is because when the sickle piece 1 is locked, it becomes a hindrance, and the sickle piece may not completely come out of the lock case 4.
[0019]
However, in relation to the invention described in claim 4 (the purpose of the invention to engage with the engagement receiving plate while capturing the sickle piece, etc.), the polarity of the engagement receiving plate 30 on the front wall 22 of the case body 21 It is not necessarily a specific requirement of the invention to provide the magnetic body 23 that repels corresponding to the above.
[0020]
In the invention described in claim 4, the magnetic body 25 is fixed to the inclined rear wall 24 of the case body 21 of the movable capturing member 17, and the tip portion 6 of the sickle piece 1 is adsorbed thereto. The reverse is also possible. That is, the second magnetic body may be fixed to the inclined attracting surface 9 of the distal end portion 6 of the sickle piece 1 while being formed of a material that attracts the case main body 21. In short, it is sufficient that the movable capturing member 17 and the sickle piece 1 are in a suction relationship. The support spring 15 may be a leaf spring.
[0021]
