[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an assembly of a door lock mechanism. More specifically, the present invention relates to an assembly of a door lock mechanism that can reliably maintain a locked state.
[0002]
[Prior art]
Conventionally, there is a mechanism that locks (locks) a door such as a door or a gate that can be freely opened and closed by hinge coupling to a building or a pillar so that the door cannot rotate with respect to the ground or floor ( For example, see Patent Document 1).
[0003]
For example, as shown in FIGS. 5 to 6, the lock mechanism includes a guide member 101 attached to a lower portion of the door 100 and an upper and lower opening of the guide member 101 so as to be slidable in a direction perpendicular to the ground 102. The drop bar 103 is inserted into the portions 101a and 101b. In this locking mechanism, the grip portion 104 is directed toward the front side of the door 100 and is inserted into the concave portion 105 formed in the ground 102 so that the door 100 cannot be rotated. In FIG. 5, reference numeral 106 denotes a locking projection, 107 denotes a notch, and 108 denotes a stopper. To release the lock state of the drop bar 103 shown in FIG. 6, first, as shown in FIGS. 7 to 8, the grip portion 104 is lifted in the F1 direction, the locking projection 106 is passed through the notch portion 107, The stopper 108 is brought into contact with the upper opening 101a of the guide member 101. In this state, since the dropping bar 103 is pulled out from the recess 105, the locking protrusion 106 is moved while the dropping bar 103 is rotated in the F2 direction (see FIG. 5) so as to be parallel to the side surface of the door 100. The guide member 101 is locked on the upper opening 101a.

[Problems to be solved by the invention]
In the conventional lock mechanism, the door can be locked so as not to move to the position where the door is closed or the lock can be released only by performing the up / down operation and the rotation operation of the dropping bar.
[0006]
However, even if it is attempted to maintain the locked state, as described above, anyone can easily release the lock. Therefore, when the lock mechanism is attached to the rear surface of the door of the house, for example, the child accidentally operates the dropping bar. There is a risk of releasing the lock and going on the street without permission. In addition, when the lock mechanism is attached to the surface of a door of a building site, for example, the child can touch the building material and injure while entering and playing with the dropping bar by operating the dropping bar. There is. Or there is a risk of building materials being stolen due to the intrusion of suspicious individuals.
[0007]
In view of the above circumstances, an object of the present invention is to provide an assembly of a door lock mechanism that can reliably maintain a locked state.
[0008]

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the assembly of the door lock mechanism of the present invention will be described with reference to the accompanying drawings.
[0011]
As shown in FIGS. 1 to 3, the assembly of the door lock mechanism according to the embodiment of the present invention includes a door lock mechanism A and a lock member B.
[0012]
The door locking mechanism A includes an L-shaped dropping bar 3 having a vertical portion 1 and a grip portion 2 protruding substantially perpendicularly from one end of the vertical portion 1, and both ends of a narrow metal plate, for example. It comprises a guide member 6 having upper and lower openings 4 and 5 bent so as to be parallel to each other. The drop bar 3 is arranged in parallel to the guide member 6 and, after being attached to the door, the upper and lower openings 4, 5 are guided so as to be slidable in a substantially vertical direction with respect to the ground. Are inserted into the openings 4a and 5a. The opening 4a of the upper opening 4 is formed with a notch 7 having a size that allows a locking projection 9 of the drop bar 3 to be described later to pass therethrough. The structure for attaching the guide member 6 to the door is not particularly limited in the present invention, but in the present embodiment, a predetermined number of the upper and lower positions of the main body portion are provided so that a screwing structure can be formed. For example, four mounting holes 8 are provided.
[0013]
The dropping bar 3 is provided with a locking projection 9 and three retaining portions 10. The locking projection 9 closes the door by lifting the dropping bar 3 inserted into the concave portion of the ground and passing it through the notch 7 and then rotating it to lock the upper surface of the upper opening 4. It is provided for releasing the locked state, that is, the locked state, and opening the door. In order to open the door in this way, the position of the locking projection 9 is the upper surface of the upper opening 4 when the dropping bar 3 is inserted into the recess 11 as shown in FIGS. The distance H from the lower end of the locking projection 9 is set to be longer than the depth L of the recess 11 formed in the ground E. Further, the retaining portion 10 is disposed at an upper position in the vertical direction from the locking projection 9, and, as shown in FIGS. 2 and 4, for example, the lower retaining portion 10 among the three retaining portions 10. Even if an attempt is made to pull out the dropping bar 3 by the lock member B inserted into the notch 7 of the upper opening 4 disposed between the stopper 10a and the middle stopper 10b, the lower stopper 10a. Is provided to prevent the dropping bar 3 from being pulled out. For this reason, the position of the lower retaining portion 10a is not particularly limited as long as it is an upper position from the locking projection 9, and is appropriately selected depending on the depth of the concave portion 11. For example, the dropping bar 3 Is set to a position below the upper opening 4 when the is inserted into the recess 11. The locking protrusion 9 and the retaining portion 10 (10a to 10c) are formed by, for example, plastic processing a part of the metal vertical portion 1 with a press, or forming a hole in the dropping rod 3, and a pin in this hole. For example, or by welding a metal square. When it is difficult to insert the metal ring B1 in the lock member B into the notch portion 7 during use, the drop bar 3 is rotated so as to be above and below the notch portion 7 as shown in FIG. What is necessary is just to insert the metal ring B1 in the notch part 7 in the state without the retaining part 10.
[0014]
In the present embodiment, two retaining portions 10b and 10c are provided in the middle and upper stages in addition to the retaining part 10a in the lower stage. This is because, for example, the depth of the recess 11 varies at the construction site. This is because the door lock mechanism A can be used for the door at a predetermined position even when it becomes deeper. For this reason, in the present invention, at least one retaining portion is sufficient. The lock member B may be of any type as long as it can be locked by inserting an inverted U-shaped metal ring (locking hook) B1 through the notch 7. The present invention is not particularly limited. Furthermore, in the present invention, the place of the guide member, have a vertical opening, each inserting the drop rod, also possible to use a pair of upper and lower guide members該落slidably guiding the rods in a substantially vertical direction it can.
[0015]
In the present embodiment, as shown in FIG. 3, whether or not the upper opening 4 is disposed above the lower retaining portion 10a in the state where the dropping bar 3 is first inserted into the recess 11 of the ground E is determined. The door lock mechanism A is screwed to a predetermined position on the lower side surface of the door D while considering. And when making the door D into the closed state, the grip part 2 is operated and the dropping stick 3 is inserted in the recessed part 11. FIG. And in order to maintain the said door D in the closed state, as FIG.2 and FIG.4 shows, the metal ring B1 is penetrated to the notch part 7 of the upper opening part 4, and the locking member B is attached. Thereby, in this Embodiment, even if it is going to pull out the dropping rod 3, the lower stopper part 10a is obstructed by the metal ring B1, and the dropping rod 3 cannot be pulled out. Therefore, the locked state of the door can be reliably maintained.
[0016]
On the other hand, when the door D is opened, the lock member B is first unlocked, and the metal ring B1 of the lock member B is pulled out from the cutout portion 7. Next, the grip portion 2 is operated to pass the locking projection 9 through the cutout portion 7, and the dropping rod 3 is lifted until the stopper 12 collides with the lower surface of the upper opening portion 4, and is pulled out from the recess 11. Then, the grip portion 2 is rotated to lock the locking projection 9 on the upper surface of the upper opening 4.
[0017]
The present invention is not limited to a rotatable door, but can be applied to a door that moves on a rail.
[0018]
