DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door stopper installed on a building such as a general building or a ship for stopping a door in an open state, and more particularly to a lower door stop type door stopper. The present invention also relates to an adapter which is additionally attached to the door stopper and used.

[0002]

2. Description of the Related Art A conventional lower door stop type door stopper is
A door stopper is provided at a position facing the door of a door stopper main body installed in a building, and a ring for engaging and locking with a hook provided on the door is provided on the door stopper main body.

[0003]

In the above-mentioned door stopper, when the door is stopped in an opened state or when the door is closed, the door is bent down and mounted on the door stopper body by hand operation each time. It was necessary to hang the ring on the hook attached to the door, which was cumbersome and inconvenient. The problem to be solved by the present invention is that, in order to eliminate the inconvenience as described above, it is necessary to hold the door lightly in the open position by magnetism or other action in a normal use state and lock it each time. The door should be securely locked in the open position with a simple operation using the foot, and released (unlocked) using the same simple operation with the foot against a relatively strong wind blow or hull swinging. The purpose of the present invention is to provide a convenient door stopper that can be used. In addition, the door stopper cannot be replaced in a building that has been restricted from renovation, and in order to eliminate the inconvenience described above, it is necessary to add convenience to the existing door stopper. The adapter is provided.

[0004]

In order to solve the above-mentioned problems, a door stopper according to the present invention is a pedal that operates in a seesaw shape using a shaft provided on a functional portion of a door stopper main body installed in a building as a fulcrum. At the door-side tip (hereinafter abbreviated as a front end), a main body-side locking portion (hereinafter, simply referred to as a locking portion a).
When a door is opened, a locking plate having a door-side locking portion (hereinafter, simply referred to as a locking portion b) is provided at a position close to the door when the door is opened, and the locking portion a is operated by operating a pedal. The door can be locked or released to the open position by bringing the two locking portions into a relational position where they can be engaged and released when moved up and down. In addition, the form of the locking part a and the locking part b may be interchanged.

In the door stopper of the present invention, a magnet is provided at a position facing the door of the door stopper main body function portion to hold (temporarily hold) the door, and a magnet is provided at the position of the door facing the door stopper. It has a function of magnetically attracting and holding both of them, and it is easy to adapt to the locking plate by fixing the magnet or holding it with a pin, and using a cushioning material. To reduce the impact when the door is sucked. Further, a rubber magnet may be used, and in that case, a cushioning material is not required.

Further, the door stopper of the present invention uses a spring and a magnetic force as one means for holding the front end of the pedal in an upper position or a lower position (which is a position relating to locking or releasing, but may correspond to either position). The pedal is pushed forward by the rotational force generated on the shaft by springs 28a and 28b or springs 28c supported by both fixed and movable support points. When a magnetically responsive portion is provided at the front end of the pedal, and the front end is lowered by operating the pedal, the pedal is attracted to the side magnetic field of the door holding magnet 22 more strongly than the pushing force of the springs 28a, b, c. When holding the position and operating the pedal to separate the magnetically responsive part of the front end from the side magnetic field of the magnet, the magnetic attraction force rapidly weakens and the spring push-up force wins, raising the pedal front end. It is kept in the state where it is made to be.

In the door stopper of the present invention, a door holding spring having an insertion portion opened in the door direction is installed in the function portion,
The locking point of the locking plate provided at the position of the door facing this is engaged, and the restoring force from the deviation of the door holding spring caused by this engagement acts to hold the locking point. Has a function of holding the door at the open position when the pedal is in the released state. The door holding spring may be formed by bending a wire.

Further, the door stopper of the present invention uses a bistable mechanism described below as one means for holding the front end of the pedal in the upper or lower position. In the sixteenth embodiment, the state of pedal holding can be identified by a display mechanism interlocked with the bistable mechanism. FIGS. 9 to 12 mainly show the pedal portion, FIGS. 13, 14 and 16 show the functional portion, and FIGS.
Numerals 3, 24, and 25 are explanatory diagrams of the mechanism and function of each of the pedal adapters, and these are applications of a bistable mechanism. In these figures, the fixed fulcrum is fixed in the rotation direction of the shaft, but may be movable with respect to the distance between the fulcrum. It moves at the same distance as the axis. In these drawings, the fixed-side fulcrum is provided on the base side, and the movable-side fulcrum is provided at any position on the pedal side, and rotates around the shaft together with the pedal.

FIGS. 9, 10 and FIGS. 13, 14 and 16 show a force in a direction in which a spring or the like (which exerts an action like a spring) is interposed between a fixed fulcrum and a movable fulcrum to move the two fulcrums away from each other. 11 and 12 and FIGS. 23, 24,
Reference numeral 25 denotes a state in which the fulcrum is supported by a supporting body or a substitute for the fulcrum, and a force in a direction to approach the fulcrum is applied by a spring or the like. [In FIGS. 23, 24, and 25, a unit in which the three parts of the attachment, the pedal adapter, and the lock ring are integrated (hereinafter abbreviated as a pedal adapter mechanism) replaces the strut.] These conditions were set. When the movable-side fulcrum is rotated about the axis together with the pedal by pedal operation, the fixed-side fulcrum in FIGS. 9 and 10, and FIGS. 13, 14 and 16, when the movable-side fulcrum is on the center line. Is the narrowest, and the spring is the most unstable position where the spring is compressed. Therefore, the movable fulcrum receives a force in the direction away from the center line by the force of the spring to expand.
In FIGS. 11 and 12 and FIGS. 23, 24 and 25, when the movable-side fulcrum is located on the center line, the mutual interval between the movable-side fulcrum and the fixed-side fulcrum becomes the largest, and the force of the spring for narrowing the distance between the two fulcrums. Is the most unstable position to oppose
The movable fulcrum receives a force in a direction away from the center line by the force of the spring to narrow the space between the two fulcrums.
[Since the movable fulcrum is provided on the pedal side, the pedal (including the pedal adapter mechanism) rotates around the shaft portion by the force received by the movable fulcrum.] Thus, the movable fulcrum is moved away from the center line. If the range of movement of the movable-side fulcrum (pedal and pedal adapter mechanism) is limited to a certain range on both sides of the center line in a state where a force in the direction acts, stop points on both sides farthest from the center line within that range. Form a bistable mechanism with a stable point at Also, if the range of movement of the movable fulcrum is limited to a certain range on one side of the center line, within that range,
This is a monostable mechanism in which the position farthest from the center line is a stable point.

In FIGS. 9 and 10 and FIGS. 13, 14 and 16, since the bending spring 38, the .OMEGA.-shaped spring 34 or the .SIGMA.-shaped spring 64 applies a force in the direction of moving the fixed fulcrum away from the movable fulcrum, As a result, the pedals driven by the respective springs exhibit a bistable state, and the push-up spring 30 and the push spring 3 in FIGS.
3 or an external spring 83, a force is applied to the fixed fulcrum and the movable fulcrum, between which the span body 39 or the pedal adapter mechanism is interposed, in the direction of bringing the two fulcrums closer from the outside. Both the pedal and the pedal adapter mechanism driven by the movable fulcrum supported by the body 39 exhibit a bistable state.

When the door stopper of the present invention is operated at the upper stable point or the lower stable point by operating a pedal provided with a window for displaying a state, the door stopper of FIG. 5, FIG. 9 to FIG. At 16, the springs or struts interposed between the fixed-side fulcrum and the movable-side fulcrum perform the bistable operation as described above in accordance with the upward and downward movements of the pedal, and move left and right with respect to the center line. This movement is transmitted to the display body, and the display body moves up and down and hides or disappears from the window, or moves in the rotation direction around the movable fulcrum, so that the colors and symbols seen from the window can be seen. Is changed (the change due to the movement of the display, which can be seen through these windows, is collectively expressed as a sign), so that the sign has a function of identifying the holding state of the pedal.

As another method of displaying the pedal setting state of the door stopper of the present invention, a display portion is provided on the side of the door stopper main body as shown in FIG. 17, and FIG. The identification pattern given to the display body 37 of
In a mechanism in which both are arranged in a related position visible through the window of the shield, one of them is fixed to the base, and the other is connected to a seesaw-shaped pedal and rotated about a shaft, When the pedal is held at the upper stable point or the lower stable point by operating the pedal, the pedal has a function of displaying the pedal holding state by selectively recognizing the identification pattern corresponding to the state through the window. .

[0013] The additional spring type adapter of the present invention comprises:
A spring adapter formed of a resilient plate material is additionally attached to a conventional door stop type door stopper main body, and the door holding spring is engaged with a locking point of a locking plate provided on the door. This is for imparting a function of holding (temporarily holding) the door by the locking force exerted on the locking point by the restoring force from the generated deviation of the door holding spring.

The additional pedal type adapter of the present invention sets a fixed fulcrum at a position where a fulcrum function can be set with respect to a conventional and existing door stopper for manually operating a lock ring. The pedal adapter mechanism is regarded as a supporting body, a fulcrum hole provided on the mounting tool is used as a movable supporting point, and a bi-stable mechanism is formed by applying a force in a direction of bringing the supporting points closer to each other by an external spring, and a pedal by a foot. This is to add a function that enables the setting of the lock and release states by operation.

The corner at the rear end of the ceiling of the 両 -shaped spring 64 is configured to support both feet of the Λ-shaped spring 64.
The pedal 23 forms a bistable mechanism as described above by applying a force in a direction to push and spread between the two fulcrums. When the front end is lowered by operating the pedal, the movable fulcrum 31b rotates around the shaft 25 and moves upward through the center line 32, so that the pedal 23 receives a clockwise rotational force due to the bistable action. The locking portion a24 at the distal end and the locking portion b91 on the door side are engaged with each other to lock the door. When the front end is raised by operating the pedal, the movable-side fulcrum 31b moves downward through the center line 32, and receives a counterclockwise rotational force, and the pedal 23 is moved as shown in FIG.
