BACKGROUND OF THE INVENTION
The present invention relates to a door stop. More specifically, it is a door stop for engaging with an engaging member that performs an operation of fixing the door in an open state and an operation of releasing the fixing with only a foot without squatting, particularly an engaging portion that engages with a hook. It is related to the door stop which greatly improved durability by increasing the strength of the door.
[0002]
[Prior art]
Conventionally, a door stop is provided on a floor or a wall in the vicinity of the fully open position of the door so that the door does not directly hit the wall or the like, and damage or noise is generated.
[0003]
Furthermore, some conventional door stops are provided with a stop ring to keep the door open, and such a stop ring is applied to an engagement target provided on the door, such as a washer with a hook. By locking by hand, the door can be fixed in the open state.
[0004]
However, when locking the door stop ring to a hooked washer or the like or removing it, it is necessary to operate the stop ring with a hand while crouching down, which is very laborious.
[0005]
Therefore, the present inventors have proposed an engaging member that can easily and reliably perform the operation of fixing the door in the open state and the operation of releasing the fixing with a foot without squatting in order to solve such a problem. did.
[0006]
For example, as shown in FIG. 3, the conventional door stop 31 is provided at the fully open position W of the door D on the floor, while the engagement member 32 is a door to be engaged with the door stop 31. It is provided at the lower end of D. The door stopper 31 and the engaging member 32 are arranged so that the door stopper 31 and the engaging member 32 collide with each other when the door D is fully opened.
[0007]
As shown in FIG. 4, the conventional door stop 31 is configured by fixing a contact portion 34 that directly contacts the engaging member 32 and absorbs an impact to an upper end portion of a shaft portion 33. In addition, an engaging portion 35 extending downward from the lower surface periphery of the contact portion 34 is integrally formed. A hook 36 of an engaging member 32 described later can be engaged with the engaging portion 35. On the other hand, the lower portion of the shaft portion 33 is screwed to an anchor bolt A screwed to the floor.
[0008]
The contact portion 34 is made of a synthetic resin such as polyacetal, synthetic rubber, natural rubber or the like having impact absorption and wear resistance in order to contact the engaging member 32.
[0009]
On the other hand, as shown in FIG. 5, the engaging member 32 that engages with the door stop 31 includes an engaging member main body 37 having a hook 36 with a tip facing upward on the front side, and the engaging member main body 37. And a compression coil spring 39 for applying an upward biasing force to the engagement member main body 37. The engagement member main body 37 is further moved to a predetermined position. A lock mechanism 40 for locking in the lower position is provided. Reference numerals 41 and 42 denote screws for fixing the guide member 38 to the door D. The locking mechanism 40 includes a locking body 43 having a locking portion 43 a rotatably mounted inside the engagement member main body 37, and a contact body 44 and a protrusion 45 provided inside the guide member 38. It is configured.

The engaging member 32 configured as described above can be engaged with the door stop 31 as shown in FIGS. 6 to 7 show the positional relationship between the door stop and the engaging member in FIG. 3 in time series, and the column II shows the operation of the locking mechanism inside the engaging member in FIG. 5 in time series. Has been shown.
[0011]
First, as shown in FIG. 6A, in a normal state, the engagement member main body 37 is pushed up to a predetermined upper position T by the urging force of the compression coil spring 39. At this time, the front surface 36a of the hook 36 is located at a height substantially opposite to the lower end of the engaging portion 35 of the door stop 31 in the horizontal direction.
[0012]
When the door D is fixed in the open state, if the door D is opened until it comes into contact with the door stop 31, the engaging portion 35 of the door stop 31 is moved as shown in FIG. Since the engaging member main body 37 is pushed down while sliding on the inclined front surface 36a of the hook 36, the hook 36 and the engaging portion 35 can be engaged with each other (see FIG. 6C).
[0013]
When the engagement between the hook 36 and the engagement portion 35 is released, the pedal 46 of the engagement member main body 37 can be pushed down with the foot F as shown in FIGS. if, because the locking portion 43a of the engaging member 43 is engaged with the projection 45, the engaging member main body 37 is locked to a predetermined lower position B _2. Thereby, the door D can be opened and closed freely.
[0014]
Further, when the engagement member main body 37 is returned to the predetermined upper position T again, as shown in FIG. Rotates, and the lock of the engagement member main body 37 is released. Thereby, the engagement member main body 37 returns to the predetermined upper position T again as shown in FIG.
[0015]
[Problems to be solved by the invention]
However, the conventional door stop 31 is integrally formed using a material having a hardness that can buffer the impact of the door, such as a synthetic resin, in which the engaging portion 35 that engages the hook 36 of the engaging member 32 together with the contact portion 34. Because it is molded, it has relatively low wear resistance and shear strength. Therefore, there is a case where the engaging portion 35 is worn or fatigued by receiving a concentrated locking force by the hook 36 over a long period of time.
