Description

[Detailed description of the invention] This invention relates to a lock holder that receives the lower end of a lock rod, such as a drop lock attached to a double door or a gate such as an entrance, such as a French drop lock, within the floor surface.

The purpose of this invention is to be able to remove soil and sand that has fallen into the jar into which the lock is inserted with a simple operation.
Another object of the present invention is to provide a lock lever holder for a drop-in lock that can be easily attached and detached without using any other jig even when the surface of the pot is installed flush with the floor or ground surface.

Conventionally, the lock holder of a drop-in lock is fixed to the floor that serves as the bottom frame of the frame for an entrance door, or to the concrete finish of the ground surface in the case of a gate; Since urns are open upwards, dirt and sand can accumulate inside the urn during use, making it difficult to lock the urn, as well as making it incomplete or almost impossible to lock. It was often necessary to remove the clogged soil.

Also, if dust or water accumulates when using it in the entrance, it will need to be removed, but since the recess of the jar is small but deep, it is almost impossible to remove it completely, and if you continue to use it as is, There were drawbacks such as the lower end of the lock rod being scratched or rubbed by the sand, and furthermore, if it contained moisture, it would lead to corrosion.

This invention was devised to eliminate the above-mentioned conventional drawbacks, and the present invention will be explained according to an example.
Fig. 1 shows a double door of an entrance to which the lock holder of the present invention is attached. A receiver is installed so that it protrudes and retracts from the lower end surface, and the lock rod 4 enters and locks into the lower frame 2 of the frame body 1.

Therefore, in the receiver of the present invention, examples of which are shown in FIG. 2 and FIG. It is attached to.

To explain this more specifically, the support frame 5 has a rectangular plate with a hole 7 into which the pot 6 is fitted and holes 9 for screws 8 that are fixed to the floor surface 14. Locking portions 10, 10 are provided at both ends in the longitudinal direction, respectively.

The pot 6 has a flange 11 on its periphery and is an upwardly open box body, and when it is fitted into the hole 7 of the supporting frame 5, the flange 11
is shaped to be supported on the upper surface of the support frame 5, and is provided with protrusions 12, 12 that engage with the locking parts 10.10 of the support frame 5, and further includes a pair of knobs inside the pot 6. 13 is installed protrudingly.

Note that the thickness of the collar 11 is approximately the same as that of the floor surface 14.

Furthermore, in the case of the structure of the locking part 10 and the protrusion 12 shown in FIG. Then, the elasticity of the protrusion 12 is used to hook and stop the locking part 10.

Further, the knob portion 13 is formed of a triangular protrusion on the inner surface of the pot 6 on the opposite wall thereof.

Next, the locking part 10 in the example shown in FIG.
The lower portions of a pair of vertically disposed pieces are bent in directions away from each other, and the jar 6 is removably fitted to the support frame 5 by the elastic opening and closing action of the protrusion 12. be.

Furthermore, the knob 13 in this example is formed similarly to the previous example.

Since the lock holder of this invention has the structure described above, in order to remove dirt, sand, water, etc. that get into the jar 6 during use, hold the knob 13 and support the jar 6. By removing the jar 6 from the frame 5 and repeating the process, accumulated soil, water, etc. can be easily removed without leaving any residue.

The lock lever holder of the drop-in lock according to this invention has a two-piece structure consisting of a support frame and a pot, and a knob is provided inside the pot. The top surface of the jar is set flush with the floor or ground surface, and because it is flush with the surface, there is no risk of people walking over it tripping over it, and even if it is stepped on by a person or car, the jar will remain intact. It can improve durability without being damaged.
