Therefore, a braking force acts as the movable door stop is pushed in, and a rotating speed of opening the hinged door is reduced. While decelerating the hinged door, the movable door stop is retracted by a fixed stroke from an outward opening regulation position by guidance of guide means G in accordance with a magnitude of the push-in external force, and released backwards while applying brake by the brake means and during the release, strong shock in a case where the movable door stop crashes into the coping, is absorbed and damped effectively.

Description

  The present invention relates to a door stop device that regulates an opening angle of an open door by holding an open door that is pivoted so as to be able to open outward in a toilet booth or the like and holding the door in an open position.

  Recently, opening doors that open and close the entrances and exits of toilet rooms partitioned by partition walls in toilet booths, etc., are pivotally pivoted by hinge brackets on sleeve walls and door frames, etc., and are lined up in series with sleeve walls when closed Supporting the closed position, the outer surface of the toilet room is made flush with the panel, and it is constructed with good appearance.

  Therefore, in the conventional door stop device, when the opening door is pivoted so as to be able to open inward to the sleeve wall by the hinge fitting, normally, when the opening door is opened inward, the door stop attached to the opening door is The opening angle is restricted by applying a right angle to the partition wall of the toilet room, which is relatively strong in structure.

  However, conventionally, even in a toilet booth, when the opening door is an outside opening structure like a storage door for storing cleaning tools etc., the partition wall cannot be used, so the outer surface is flush with the opening door. There is a door-to-door structure that regulates the outside opening angle by hitting the door to the sleeve panels to be formed and the caps between the sleeve panels. This kind of door stop has an attachment part and a holding part that are attached to a sleeve panel or the like, and has a structure in which a rubber plate is attached to the holding part for buffering (see Patent Document 1).

JP-A-9-151616

  However, in the case of the doors of conventional open doors, even if you try to cushion the impact by hitting a rubber plate, the inside will be supported by a relatively low-strength member such as a hollow sleeve panel or a slender headboard. If a large external force is applied that pushes the door open with force exceeding the regulation angle, the shock that is received at that time cannot be sufficiently buffered, resulting in damage to the hinge fittings such as hinges and angles. Depending on the situation, there was a problem that the door could break and break.

  Accordingly, an object of the present invention is to provide a door opening device or hinge fitting that sufficiently cushions the severe impact received at that time even in the case of a large external force that pushes the opening door with a strong force in a door-contacting device for an outward opening door. It is to protect the surroundings of the door so as not to break.

  According to the first aspect of the present invention, for example, as shown in the embodiment shown below, the open door D that opens and closes the entrance / exit of the room partitioned by the partition wall is pivoted so that it can be opened outwardly. In the door structure supported in the closed position arranged in series with 12, when opened, the sleeve wall 11 of the opening door D is contacted with the sleeve wall 11 of the abutting member or the cap 13 passed between the sleeve walls 11, 12. A door-contacting device R that regulates the opening angle with respect to the support door 15, which is fixed to the upper end of the opening door D, and bent in a direction parallel to the opening door D when the support portion 15 is closed. A support arm S composed of an arm portion 20 on the other end side, a movable door contact A engaged with a distal end of the support arm S so as to be movable in the length direction of the arm portion 20, and the movable door contact A are When pressed against the contact member, a braking force is generated to reduce the rotational speed at which the opening door D opens. Thus, the braking means B acting on the movable door contact A and the movable door contact A are stopped and held at the opening restriction position which normally restricts the opening angle of the opening door D. And a guide means G for guiding the movable door against the braking force when the movable door contact A is pushed in so as to move backward from the outer opening restriction position by a predetermined stroke according to the magnitude of the pushed-in external force. .

  According to a second aspect of the present invention, in the door stop device R according to the first aspect, for example, as shown in the embodiment shown below, the support arm S is closed at the upper end of the opening door D when the sleeve is closed. The arm portion 20 is attached so as to be arranged on the indoor side in a state of being bent in a parallel direction with respect to the opening doors D arranged in series with 11 and 12.

  According to the first aspect of the present invention, when opened, the opening door may be loosely opened or forcibly pushed open with a momentum exceeding the outside opening restriction angle, but it opens with such a strong force. Even if the door is violently pushed open and the movable door hits against an abutting member such as headboard, the movable door is pushed against the braking force of the braking means, so the braking force works accordingly and the open door While the speed of the opening is reduced and the opening door is decelerated, the movable door contact is retracted by a fixed stroke from the outside opening restricting position according to the guidance of the guide means according to the magnitude of the external force to be pushed. Since the brakes are released at the rear while applying the brake, the strong impact when the movable door hits against the abutting member can be absorbed and buffered effectively. As a result, the opening door can be opened wildly. By door Hinge bracket can be protected so as not to break around the door like.

    According to the second aspect of the present invention, the door stop device is a door structure that, when closed, supports the open door in a closed position in series with the sleeve wall and forms the entire outer surface of the chamber with the panel. On the other hand, it is possible to prevent the appearance around the door from being deteriorated by placing it inside so that it does not protrude and is not visible from the outside.

On the door contact surface, a horizontally long engaging rib 17 is provided above the mounting recess 18a, and a pair of guide pins 35 corresponding to the guide holes 30 of the pressing portion 20a are provided on the spring mounting recess 18b. In addition, the upper end of the guide shaft 40 is pivotally attached to the bottom portion and hangs down. The buffer pad 19 is made of, for example, rubber, and the front door contact surface 19a is formed of a curved surface, and an engagement groove 19b corresponding to the engagement rib 17 on the door contact main body 18 side is provided on the back side. . Therefore, the movable door contact A is formed by engaging the engagement rib 17 in the engagement groove 19b and assembling the buffer pad 19 on the door contact main body 18 (see FIG. 1). The buffer pad 19 is not limited to rubber as long as it has a cushioning performance, and an appropriate elastic material such as a resin material or a sponge material can be used.

  In the illustrated example, a pair of compression coil springs is used as the braking means B for the movable door A. On the other hand, as shown in FIGS. 4 and 5, the guide means G for guiding the operation of the movable door contact A includes a guide groove 25 and a guide hole 30 provided in the support arm S and a guide pin provided in the movable door contact A. 35 and a guide shaft 40.

  Therefore, the door stop device R winds the compression coil spring B of the braking means around the guide pin 35, temporarily compresses the compression coil spring B, and fits the tip of the guide pin 35 into the guide hole 30 of the support arm S. The guide shaft 40 is engaged with the guide groove 25, and the protruding rail portion 18c is engaged with both side edges of the arm portion 20, so that the movable door contact A is the length of the arm portion 20 as shown in FIG. Attach to the tip of the support arm S so that it can move in the direction. Then, as shown in FIG. 1 (A) and FIG. 6 (A), the door stopper device R applies the guide shaft 40 of the guide means G to the groove edge of the guide groove 25, and opens the movable door stopper A to the open door. Stop and hold at the outer opening restricting position that restricts the outer opening angle of D. Accordingly, in the door stop device R, as shown in FIGS. 1B and 6B, the movable door stop A is pushed in against the spring biasing force (braking force) of the compression coil spring (braking means) B. Then, the guide shaft 40 is engaged with the guide groove 25 of the guide means G and the guide pin 35 is engaged with the guide hole 30 so as to retreat by a fixed stroke from the outer opening restricting position in accordance with the magnitude of the pushing external force. It is configured to guide.

  As shown in FIG. 2, the door stop device R according to the first embodiment is configured such that, at the upper end of the opening door D, the latching portion 15 a is hung on the outer side (outside) door side edge and the support portion 15 of the support arm S is supported. Is fixed with screws, and when closed, the arm portion 20 is attached so as to be arranged on the inner side (inner side) in a state of being bent in a parallel direction with respect to the opening door D arranged in series with the sleeve walls 11 and 12. Therefore, the door stop device R according to the first embodiment is such that when it is closed, the door D is supported in a closed position in series with the sleeve walls 11 and 12 and the outer surface of the toilet room is formed flush with the panel. In the structure, it is not arranged so as to protrude outward, and is placed inside so that it cannot be seen from the outside, so that the appearance around the door does not deteriorate.

  Now, when the door stop device R having the above-described configuration is opened from the indoor side by rotating the opening door D to the outside indicated by the arrow in FIG. 2, it rotates integrally with the opening door D, as shown in FIG. When the opening door D rotates by an outward opening restriction angle perpendicular to the sleeve walls 11 and 12, the buffer pad 19 of the movable door A presses against the headboard 13 to stop the rotation of the opening door D, and the opening door D has a wide angle. The degree of outward opening is restricted at right angles to the sleeve walls 11 and 12 so as not to open too much. At that time, when the movable door contact A is pressed against the headboard 13 against the spring biasing force of the compression coil spring (braking means) B, a braking force is applied, and the movable door end A is pressed against the headboard 13. Shock is buffered. At the same time, since the buffer pad 19 attached to the door-to-door main body 18 hits the headboard 13, the impact when hit is also buffered by the buffer pad 19.

  However, at the time of opening, the opening door D may be violently opened or forcibly pushed open with a momentum exceeding the outside opening restriction angle. However, in the door stop device R according to the present invention, even if the movable door stop A collides with the headboard 13 because the opening door D is violently pushed open with such a strong force, FIG. 1 (B) and FIG. 6 (B). As shown in FIG. 2, the movable door contact A is pushed against the spring biasing force of the compression coil spring (braking means) B by being pushed by the pressing portion 20a of the support arm S, and accordingly the braking force is applied. The rotational speed at which the door D opens is reduced, and the door A is decelerated by the guide means G from the outer opening restriction position according to the magnitude of the external force to be pushed in, while the door D is decelerated. In this way, the brake means B releases the rear while applying the brake, and during that time, the movable door A can absorb the strong impact when it collides with the coping 13 and can effectively buffer it. Open the door roughly It can be protected so as not to break around the door, such as door and the hinge bracket by.

  When the door stop device R according to the first embodiment described above is opened by rotating the door D outward, the door A is applied to the headboard 13 to stop the rotation of the door D, and the door D is opened outward. The angle is restricted at right angles to the sleeve walls 11 and 12. However, in the present invention, as in the door stop device R ′ of the second embodiment shown in FIG. 7, the opening of the opening door D is stopped by stopping the rotation of the opening door D by putting the movable door stop A ′ against the sleeve wall 11. It can also be configured to regulate the angle. Accordingly, even if the door structure of the hinged door is not provided with the headboard 13, the outward opening angle of the hinged door D can be regulated.

  Then, the door stop apparatus R 'which concerns on 2nd Embodiment is demonstrated below along FIGS. In addition, in 2nd Embodiment, the structure same as the door stop apparatus R of 1st Embodiment attaches | subjects and demonstrates the same code | symbol.

  In the door stop device R ′ of the second embodiment, as shown in FIG. 9, the support arm S is a metal angle plate bent in a substantially L shape, and includes a support portion 15 on one end side and a short side on the other end side. Arm portion 20. The arm portion 20 has a pair of locking projections 20b protruding from both ends of the arm portion 20 at the tip, and an elongated guide groove 25 is provided along the longitudinal direction near the support portion 15 of the locking projection 20b. ing.

  The movable door contact A 'is made of resin, and the front door contact surface 50 is formed of a curved surface, while it is formed into a flat cap shape with an opening for the support arm S on the opposite side. A mounting hole 55 for the guide shaft 40 penetrating between the flat and bottom portions is provided. The pair of compression coil springs of the braking means B are attached to the tip of the support arm S via the spring attachment 45. The spring attachment 45 is formed by standing a pair of guide pins 35 on the attachment base 39. The mounting base 39 is provided with locking recesses 39a corresponding to the locking protrusions 20b of the support arm S at both ends in the length direction. The guide means G for guiding the operation of the movable door contact A ′ is constituted by a guide groove 25 provided in the support arm S, a guide pin 35, and a guide shaft 40 provided in the movable door contact A ′.

  Therefore, in the door stop device R ′ of the second embodiment, the locking projection 20b of the support arm S is fitted into the locking recess 39a, and the spring mounting tool 45 is attached to the tip of the support arm S. After the compression coil spring B of the braking means is wound, the compression coil spring B is temporarily compressed by covering the movable door A ′, and the guide shaft 40 is passed through the mounting hole 55 in the meantime and engaged with the guide groove 25. Then, as shown in FIG. 10A, the movable door contact A ′ is attached to the tip of the support arm S so as to be movable in the length direction of the arm portion 20 and assembled. Then, the door stop device R ′ applies the guide shaft 40 of the guide means G to the groove groove on one side of the guide groove 25 to restrict the movable door contact A ′ from the opening angle of the opening door D. Stop and hold. Therefore, as shown in FIG. 10B, the door stop device R ′ of the second embodiment has a movable door stop A ′ that opposes the spring biasing force (braking force) of the compression coil spring (braking means) B. When pushed, the guide shaft 40 is engaged and guided in the guide groove 25 of the guide means G so as to retreat by a fixed stroke from the outer opening restriction position according to the magnitude of the pushing external force.

  As shown in FIG. 8, the door stop device R ′ of the second embodiment fixes the support portion 15 of the support arm S with a screw at the upper end of the opening door D and is in series with the sleeve walls 11 and 12 when closed. It attaches so that it may be arrange | positioned on the outer side (outdoor side) in the state which the arm part 20 bent in the parallel direction with respect to the opening door D located in a line.

  Now, when the door stop device R ′ having the above-described configuration is opened from the indoor side by rotating the opening door D to the outside indicated by the arrow in FIG. 8, the door closing device R ′ rotates integrally with the opening door D, as shown in FIG. When the door D is rotated by an outward opening restriction angle that is perpendicular to the sleeve walls 11 and 12 of the contact member, the door contact surface 50 of the movable door A 'is pressed against the sleeve wall 11 and the door D is rotated. And the degree of outward opening is restricted at right angles to the sleeve walls 11 and 12 so that the opening door D does not open too wide. At that time, the movable door contact A ′ is pressed against the sleeve wall 11 against the spring biasing force of the compression coil spring (braking means) B, so that the braking force is applied and the movable door contact A ′ is against the sleeve wall 11. The impact when pressed is buffered. At the same time, since the resin cap-shaped movable door contact A ′ hits the sleeve wall 11, the impact at the time of contact is also buffered by the material / shape of the movable door contact A ′ itself.

  However, in some cases, the opening door D may be loosely opened or forcibly pushed open at a moment that exceeds the outside opening restriction angle when it is opened. Even if the door A ′ collides with the sleeve wall 11 because the door D is violently pushed open with a strong force, the door A ′ is compressed by the support arm S as shown in FIG. Since it is pushed against the spring biasing force of the coil spring (braking means) B, the braking force works accordingly to reduce the rotational speed at which the opening door D opens, and while the opening door D is decelerated, A 'is moved backward by a fixed stroke from the outside opening restricting position according to the guidance of the guide means G according to the magnitude of the external force to be pushed in. In this way, the brake means B releases the back while applying the brake. A 'on the sleeve wall 11 It is possible to absorb a strong impact at the time of a collision and effectively buffer the impact, and as a result, by opening the opening door roughly, it is possible to protect the door and hinge fittings from being broken.

  In the above-described illustrated embodiment, the compression coil spring is used as the braking means B. However, the present invention is not limited to this, and is controlled by other elastic materials such as springs, rubber and sponge, and the viscous resistance of the viscous liquid. It is also possible to use a damper that generates power, an air brake, or the like.
