Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a door opening holding device for maintaining a door in an open state.

[Conventional technology]

Conventionally, as the above-mentioned holding device,
Those disclosed in Japanese Utility Model Publication No. 75067 and Japanese Utility Model Application Publication No. 58-27467 are known.

These devices hold the door open by rotating the foot rod down and bringing it into contact with the floor.
When the door is closed, the foot bar is configured to rotate upward, so the rotation operation of the foot bar is performed with the tip of the foot, but when in use, the foot bar is rotated and raised.
When changing from a used state to a non-use state, each operation is performed on the instep side of the toe, which not only requires two operations, but also makes it difficult to perform the operation, especially when changing from a used state to a non-use state. There are operational problems such as difficulty in obtaining sufficient rotational force of the foot rod, and the problem that the instep side of the shoe is easily damaged.

[Problem that the invention attempts to solve]

Therefore, as a result of studies in view of the above-mentioned problems, the present invention has been developed by configuring the foot bar to be able to slide up and down, so that it can be put into a used state and a non-used state by simply stepping on it with the back of the foot. Even if there is a height difference in the floor surface or the floor surface is sloping, the foot rod rotates accordingly and comes into contact with the floor surface, so that the foot can be opened without damaging the shoes. Its purpose was to be able to hold the door.

[Means for solving problems]

That is, in the present invention, the upper end of the foot rod and the spring receiver are pivotally connected to the slider, and the slider is rotated.
is attached to the guide plate fixed to the door so as to be able to slide up and down, and a push-up spring is interposed between the spring receiver and the guide plate receiving part to push it down against the push-up force. The guide plate is provided with a protrusion capable of releasably locking the tip of the spring holder so as to be able to hold it in position, and the guide plate has a tip that has an appropriate sliding resistance with the foot rod. A stopper is rotatably attached to the stopper, and the lower end of the stopper is provided with an arcuate surface centered on the pivot point of the foot rod, so that the foot rod can be rotated and held at a desired angle. The above problem was solved by configuring the system as follows.

and the left and right side plates 3 of the guide plate 3.
The sliders 4, 4 and the slider receiver 5 are assembled to the guide plate 3 so as to be slidable in the vertical direction as one body while being guided by the sliders 4, 3b.

The upper end 1a of the foot rod 1 and the substantially central portion of the spring receiver 2 are pivotally connected to the slider receiver 5 with a pin 15 so as to be rotatable in the vertical direction. The portion 2a is slidable in the vertical direction along the wall surface of the guide plate 3, and between the spring receiver 2 and the receiving portion 3c curved at the lower end of the guide plate 3, there is a A spring 6 is interposed, and the resiliency of the spring 6 causes the foot rod 1, the spring receiver 2, the sliders 4, 4, and the slider
The receiver 5 is integrally urged upward.

Further, the guide plate 3 is provided with a protrusion 16 that can detachably lock the tip end 2a of the spring receiver 2 so that the foot rod 1 etc. can be held in a predetermined position pushed down against the upward force of the spring 6. It is protruded from the inner surface of the.

The head of the mounting screw 12 of the guide plate 3 can also be used as the projection 16 as shown in the illustrated example.

Further, the stopper 7 is formed in the shape of a horizontally long plate, and its base end is pivotally attached to the lower part of the side wall 3d of the protrusion 3a of the guide plate 3 by a rivet 17 or the like so as to be rotatable in the vertical direction. There is.

In the illustrated example, two stoppers 7 are used, so in such a case, the stoppers 7, 7 should be pivoted to the left and right side walls 3d, 3d of the protrusion 3a as shown in FIG. The regulating plate 7c comes into contact with the side walls 3d, 3d, so that downward rotation from the illustrated position is regulated.

Further, the stopper 7 is formed to a length such that its tip 7a and the front wall 1b of the foot rod 1 come into contact with each other and provide appropriate sliding resistance when the foot rod 1 is lowered. The lower part thereof is formed into an arcuate surface 7b along an imaginary circle centered on the pivot point of the foot bar 1, that is, the pin 15, and
In the operating state shown in the figure, the foot rod 1 can be freely rotated in the door opening direction indicated by arrow a in the figure.

In other words, the foot bar 1 is configured such that the upper end surface 1d of the front wall 1b thereof, which is cut out, is guided by the arcuate surface 7b and rotated in the direction of the arrow a.

In the above configuration, usually the foot rod 1,
Spring receiver 2, slider 4, 4, slider
The receiver 5 is held in a raised position by a spring 6 as shown in FIG. 3, and in this state the door 11 can be freely opened and closed.

Further, as shown in the figure, the foot rod 1 is held vertically, and the tip 7a comes into contact with the foot rod 1, so that the stopper 7
is held in an upwardly rotated position.

To hold the door 11 open, open the door 11 to a desired angle and then step down on the slider holder 5 with the back of your foot, compressing the spring 6 and opening the slider holder 5 and the sliders 4, 4. , the spring receiver 2 and the foot rod 1 are lowered together along the guide plate 3 as shown in FIG. Since it is locked as shown in Figure 1,
The foot rod 1 and each of the above members are held in a predetermined position,
In this state, a pushing force is accumulated in the spring 6.

When the slider holder 5 is depressed as described above,
Front wall 1b of foot rod 1 and tip 7 of stopper 7
Since they are in contact with each other, the contact resistance causes the stopper 7 to move from the position shown in Fig. 3 to the rivet 17.
Rotate clockwise in the figure around .
As a result, the foot rod 1 rotates around the pin 15, rotates in the door closing direction and is pushed out as shown in FIG. 1 is pushed widest in the door closing direction, and the rubber 10 comes into contact with the floor surface 18 and is held in the position shown in FIG. It is maintained in

In addition, at this time, if the height of the floor surface 18 has changed, the floor surface 18 is sloped, or the floor surface 18 is uneven and there is a difference in height, the foot rod 1 should be moved to the first position.
The contact rubber 10 rotates in the direction indicated by arrow a in the figure.
Since the door can be brought into contact with the floor surface, it has the function of keeping the door open even in such a case.

Next, to release the open holding of the door 11, step on the base end 2b of the spring holder 2 with the back side of your foot in the state shown in FIG. As it rotates, the tip 2a comes off the protrusion 16 as shown in FIG.

Next, when the spring receiver 2 is released, the foot rod 1, the spring receiver 2, the sliders 4, 4, and the slider receiver 5 are pushed up together by the spring 6 and moved upward as shown in FIG. , the door open hold is released.

At this time, the stopper 7 is rotated counterclockwise by the sliding resistance with the foot rod 1, so that the foot rod 1 becomes vertical as it moves upward.

[Effect of idea]

Since the door opening holding device according to the present invention has been constructed as explained above, when the foot bar 1 is set to the operating state or reset to the non-using state, the slider receiver 5 and the spring are All you have to do is step down on the receiver 2, and you only have to step on the back of your foot, so the operation is simpler and easier than in the conventional case, and it also prevents damage to the instep of the shoe. Without further ado, again
An arcuate surface 7b is provided at the lower end of the stopper 7 so that the foot rod 1 can be rotated in the direction of opening the door. Even if the surface 18 is uneven and has a difference in height, the foot rod 1 can rotate and the contact rubber 10 can come into contact with the floor surface 18, so that it can be adapted to the floor surface situation. This has practical effects such as being able to hold the door in any open position without requiring special operations.
