Description

The present invention relates to an opening / closing control mechanism for a door body (door body) such as an entrance door.

As a door of various buildings such as apartments and general houses, the door body is provided on the hanging side (door end side of the door body) of the door body, and the door body is placed around the axis extending in the vertical direction using a hinge (door frame). A hinged door that is rotatably attached to the door and opens and closes the opening is often used.

On the other hand, in a door that opens and closes the door body using a hinge, the door body may suddenly close and generate a loud impact sound, or in some cases, the user may be injured. A door closer is provided by connecting to a structure such as a wall to prevent the door body from closing suddenly. However, since this type of door closer is largely exposed on the upper side of the door body and the like, there is a problem that the appearance is deteriorated.

On the other hand, in Patent Document 1, "a cam bush that can be moved up and down and a compression coil spring that gives a downward urging force to the cam bush are provided in the hinge barrel, and the door body and the hinge are opened. When the state is reached, the compression coil spring is urged in the downward direction by the cam bush to be compressed with the cam pin as the fulcrum, and when the open state is released, the door body is automatically opened by the restoring force of the compression coil spring and the damper function. A hinge equipped with an automatic opening / closing mechanism (closing mechanism, opening / closing control mechanism of a door body) that closes and enters a closed state. "

Patent Document 2 describes a hinged door provided with "a spring mechanism that generates an autistic closing force for closing an opened door and a hydraulic mechanism that generates a braking force that opposes the autistic closing force when the door is closed. A back check means made of a spring member such as a countersunk spring or a compression coil spring is attached to the upper part of the cylinder, which is a closer and the piston of the hydraulic mechanism connected to the door side hinge moves according to the opening / closing operation, and the door. A hinged door closer with a limited opening angle (closing mechanism, door body), which is characterized by providing a stop means at which the piston hits and stops the movement when the door is opened to the maximum allowable opening angle. A hinge with an open / close control mechanism). ”Is disclosed.

Further, the inventor of the present application has invented a door having a hinge having a closing mechanism for controlling the opening and closing of the door body by balancing the restoring force of the spring and the opening and closing speed adjusting force of the door body by hydraulic pressure. Has already filed a patent application for this invention (Japanese Patent Application No. 2018-065811).

In the hinges shown in Patent Document 1, Patent Document 2, and Japanese Patent Application No. 2018-065811, the closing mechanism can prevent the door body from being closed suddenly, and the closing mechanism is incorporated into the hinge. It is possible to prevent the appearance from becoming unpleasant.

Further, by incorporating the closing mechanism into the hinge in this way, it becomes possible to effectively utilize the installation position of the conventional door closer. For example, by eliminating door closers, lighting, air curtains, roll screens, etc. can be installed separately.

Here, for example, in a hinge (door) provided with the above-mentioned closing mechanism by the inventor of the present application, the internal cylinder makes a piston movement with a stroke of 9 mm at the time of opening and closing, and the oil flow rate is controlled accordingly to the door. It is configured to adjust the closing speed of the main body.

In the control by the closing mechanism that adjusts the closing speed (opening / closing speed) of the door body, for example, as shown in FIG. 9, the initial posture in which the door body 100 is closed is set to 0 °, and the maximum opening angle is set to 100 °. In this case, the closing mechanism functions at 80 to 0 °, and between 100 and 80 °, the closing function depends on the balance between the restoring force of the spring and the opening / closing speed adjustment force of the door body by flood control. It will be a free section that does not work.

Therefore, in the free section of 100 to 80 °, the stop does not work, so that the door body 100 opens without permission due to, for example, the wind. In addition, when the door body 100 is blown up by a strong wind, the door body 100 opens vigorously, causing an accident in which a user or the like is pinched, or a collision of the door body 100 causes a loud impact sound or damage to a product or part. -There is a risk of problems such as deformation, and there is room for improvement in this regard.

One aspect of the opening / closing control mechanism of the door body of the present invention is a mechanism for controlling the opening / closing movement of the door body rotatably provided around an axis extending in the vertical direction on the door end side, and is a predetermined position of the door body. The closing mechanism of the first opening / closing control mechanism that adjusts the closing speed of the door body in the opening range of the door body and the opening / closing movement of the door body are controlled in the opening range other than the predetermined opening range of the door body. It is provided with a shock absorbing mechanism of a second opening / closing control mechanism.

It is a figure which shows the function of the opening / closing control mechanism of a door body provided only with the conventional closing mechanism.

Hereinafter, the opening / closing control mechanism of the door body according to the embodiment will be described with reference to FIGS. 1 to 8.

Here, the present embodiment relates to a mechanism for controlling a door body that is rotatably supported by a hinge attached to a door tail and opens and closes an opening formed in a building. In the present embodiment, the door body according to the present invention will be described as a door body (door) that opens and closes an opening of a building such as an entrance door, but the present invention describes a window that opens and closes and an interior door. Of course, it can also be applied to the opening / closing control of other doors such as storage / closet doors and doors and exterior gates.

The door 1 of the present embodiment is, for example, as shown in FIGS. 1 and 2, a door frame 2 attached to a peripheral end portion forming an opening H of a building, and a door body (door body) for opening and closing the opening. 3 and a hinge 4 that rotatably connects the door end of the door body 3 to the door frame 2 around the axis O1 extending in the vertical direction T1 and supports the door body 3 so as to be openable and closable. ..

The door frame 2 includes a hollow structure hanging side vertical frame (door tail side vertical frame) 5, a door tip side vertical frame 6, and the upper ends of the hanging source side vertical frame 5 and the door tip side vertical frame 6. It is configured to include upper and lower horizontal frames 14 arranged so as to connect the lower ends to each other. The door frame 2 may be composed of only the vertical frames 5 and 6.

The door body 3 includes a pair of left and right vertical core members 7, a pair of upper and lower horizontal core members 9 and 10 connecting the upper ends and lower ends of the pair of vertical core members 7 and 8, respectively, and a pair of left and right vertical cores. It is connected and fixed to the materials 7 and 8 and a pair of upper and lower horizontal core materials 9 and 10, and is arranged so as to sandwich the vertical core materials 7 and 8 and the horizontal core materials 9 and 10 to form the front and back surfaces of the door body 3. Arranged so as to fill the internal space surrounded by the inner side plate 11 and the outer face plate 12, the pair of left and right vertical core members 7, 8 and the pair of upper and lower horizontal core members 9, 10, the inner side plate 11, and the outer face plate 12. It is configured to include a heat insulating material 13.

Further, the door body 3 of the present embodiment is formed by incorporating a vertically long double glazing 34 on the hanging side and a horizontally long double glazing 35 on the upper part for daylighting. The vertically long double glazing 34 is provided between the vertical core material 7 on the hanging side and the auxiliary vertical core material 36 arranged in parallel with the vertical core material 7. The horizontally long double glazing 35 is provided between the upper horizontal core member 9 and the auxiliary horizontal core member 37 arranged in parallel with the horizontal core member 9.
The door body 3 does not necessarily have to be configured as described above.

As shown in FIGS. 2, 3, 4, 5, and 6, the hinge 4 has a lower cylinder portion 16 that inserts and holds the shaft 15 inside, and a portion that protrudes upward from the lower cylinder portion 16. It is configured to include an upper cylinder portion 17 in which the shaft 15 is fitted inside and is rotatably arranged around the axis (axis center) O1.

The lower cylinder portion 16 is integrally provided with a mounting portion 18 for projecting to the hanging source side vertical frame 5 side and connecting to the hanging source side vertical frame 5.

An arm portion 19 having an L-shaped cross section is integrally provided on the upper cylinder portion 17, and a horizontal adjusting member 20 is attached to the arm portion 19.

In the hinge 4 of the present embodiment, the mounting portion 18 of the lower cylinder portion 16 is connected to the hanging side vertical frame 5 of the door frame 2 via the horizontal adjusting member 20 and the bracket 21, and the arm portion 19 of the upper cylinder portion 17 is connected. Is connected to the vertical core member 7 of the door body 3 via the bracket 22 to support the door body 3 so as to be openable and closable.

The hinge 4 of the present embodiment is attached to the hanging base side vertical frame 5 so that its shaft 15 is located in the hanging base side vertical frame 5. A part of the upper cylinder portion 17 and the lower cylinder portion 16 of the hinge 4 is projected outward if the shaft 15 (axis center) of the hinge 4 is located inside the side surface of the vertical frame 5 on the hanging side. Although it may be used, it is preferable that it fits inside the side surface of the hanging side vertical frame 5.

By the way, the door 1 of the present embodiment can be made difficult to see by configuring the hinge 4 as described above, and the design can be improved.

Further, by attaching the mounting portion 18 of the lower cylinder portion 16 to the prospective surface of the vertical core member 7 of the door body 3 via the bracket 21, the vertical and horizontal positions of the door body 3 are adjusted with the door 1 open. If the door 1 is opened, the installation can be adjusted, and the workability and maintainability can be improved.

Further, by attaching the hinge 4 to the vertical frame 5 on the hanging side via the bracket 21, it becomes easier to realize a structure in which the hinge 4 cannot be seen by the bracket 21 when the door 1 is closed, and the design is improved. It can be improved further.

On the other hand, the door 1 of the present embodiment is provided with an opening / closing control mechanism A of the door body 3 that exerts a closer function, a tilt stop function, and a stop function according to the opening degree of the door body 3.

The opening / closing control mechanism A of the present embodiment is built in the upper cylinder portion 17 of the hinge 4 and the like, like the hinges of Patent Document 1, Patent Document 2, and Japanese Patent Application No. 2018-065811 described above, and the closing speed of the door body ( The impact that controls the opening and closing of the door body 3 in the closing mechanism (first opening / closing control mechanism) A1 that adjusts the opening / closing speed) and, for example, in the free section that is not controlled by the closing mechanism A1, as in the example shown in FIG. It is configured to include an absorption mechanism (second open / close control mechanism) A2.

Further, the shock absorbing mechanism A2 of the present embodiment follows the rotational operation of the upper cylinder portion 17 of the hinge 4 that rotates around the axis O1 extending in the vertical direction T1 according to the opening / closing operation of the door body 3 in the axial direction O1 direction. A push / retreat mechanism 26 having an advancing / retreating member (raising member) 25 and an advancing / retreating member 25 of the advancing / retreating mechanism 26 advance in the axis O1 direction and come into contact with each other, and a push that suppresses further advancement (advance speed) of the advance / retreat member 25. It is configured to include an opening restraint mechanism 27 that suppresses the opening of the door body 3 by applying a pressure (restoring force).

The advancing / retreating mechanism 26 has a guiding member 28 having an upper end formed in a substantially cylindrical or substantially cylindrical shape having an uneven shape in the direction of the axis O1 and coaxially and integrally fixed above the upper cylinder portion 17, and an upper end of the guiding member. The advancing / retreating member 25, which is formed in a substantially cylindrical or substantially cylindrical shape with a concavo-convex lower end so as to fit (mesh) in a concavo-convex shape, and is coaxially arranged above the guiding member 28, and the guiding member 28 and A substantially cylindrical guide member 29 that includes the advancing / retreating member 25 and guides the advancing / retreating member 25 in the vertical direction is provided.

Further, the upper end portion of the guiding member 28 and the lower end portion of the advancing / retreating member 25 that are fitted to each other move the advancing / retreating member 25 along the axis O1 as the door body 3 rotates around the axis O1 of the upper cylinder portion 17 in response to the opening operation. It is said to be a guiding part and a guided part that advance (raise up) upward in the direction.

That is, when the door body 3 is opened from the closed state and the upper cylinder portion 17 of the hinge 4 rotates in one direction around the axis O1, the advance / retreat mechanism 26 advances / retreats along the guide portion of the guide member 28 according to the amount of rotation. The guided portion of the member 25 slides, and the advancing / retreating member 25 gradually advances upward in the axis O1 direction while being guided by the guide member 29.

Further, when the door body 3 is closed and rotated in the other direction around the axis O1, the advancing / retreating member 25 gradually retracts downward in the axis O1 direction, and the advancing / retreating member 25 completely retracts to the upper end of the guiding member 28. The lower end of the advancing / retreating member 25 fits.

On the other hand, the opening restraint mechanism 27 is a gas spring (elastic member), for example, a tubular cylinder 30 having a closed upper end portion, a piston (not shown) disposed inside the cylinder 30, and an upper end of the piston. A piston rod 31 that projects downward from the opening at the lower end of the cylinder 30 in the direction of the axis O1 and a press that is formed to have a diameter larger than that of the piston rod 31 and is coaxially provided at the lower end of the piston rod 31. It is configured to include a plate (board) 32 and a compressed fluid such as gas or oil that compresses when the piston moves rearward in the axis O1 direction to generate a reaction force.

The opening / retreating mechanism 27 is arranged coaxially with the advancing / retreating mechanism 26, and the pressing plate 32 and the advancing / retreating mechanism 26 (in this embodiment, a magnet (adsorption member) 33 attached to the upper end of the advancing / retreating member 25 described later). ) With a predetermined gap.

Here, in the present embodiment, a magnet (adsorption member) 33 is attached to the upper end of the advance / retreat member 25 of the advance / retreat mechanism 26, and abuts and attracts the metal pressing plate 32 to hold the advance / retreat member 25. It is configured as follows. That is, the magnet 33 constitutes an open / close holding mechanism that attracts the pressing plate 32 when the desired opening degree is reached and holds the door body 3 at the desired opening degree. Further, the timing at which the magnet 33 and the pressing plate 32 are attracted is determined by the separation distance between the magnet 33 and the pressing plate 32 in the state of 0 ° in the initial posture in which the door body 3 is closed, which will be described later. In the present embodiment, the door body 3 is attracted. The magnet 33 is configured to be attracted to the pressing plate 32 when the temperature reaches 80 °.

A suction position adjusting mechanism for adjusting the position of the magnet 33 is provided, and the separation distance between the magnet 33 and the pressing plate 32 in the state of 0 ° in the initial posture when the door body 3 is closed (when the magnet 33 is attracted to the pressing plate 32). The opening degree of the door body 3: suction timing) may be freely changed.

In the opening / closing control mechanism A of the present embodiment having the above configuration, as shown in FIG. 7, for example, when the initial posture in which the door body 3 is closed is 0 ° and the maximum opening angle is 100 °, 0 to 0 At 80 °, the closing mechanism A1 acts on the opening, so an external force is manually applied to open the door up to 80 °. Further, at 0 to 80 °, the advancing / retreating member 25 of the shock absorbing mechanism A2 gradually advances upward, but the shock absorbing mechanism A2 does not act on the opening / closing movement.

Next, for example, when the opening degree of the door body 3 reaches 80 °, the magnet 33 abuts on the pressing plate 32 of the opening restraining mechanism 27 and attracts the magnet 33.

As a result, in the opening / closing control mechanism A of the present embodiment, the magnet 33 abuts and attracts the pressing plate 32 of the opening restraining mechanism 27, so that the advancing / retreating member 25 is held and the door body 3 has an opening degree of 80 °. Can be held in a state.

Next, when the opening degree of the door body 3 becomes 80 to 100 °, the piston is gradually pushed in and compressed together with the pressing plate 32 and the piston rod 31 by the advancement of the advancing / retreating member 25, and the pressing plate 32 of the opening restraining mechanism 27 gradually pushes the piston. The pressing force acting on the advancing / retreating member 25 increases. As a result, the deterrent force that suppresses the opening of the advancing / retreating member 25, the guide member 28, and the upper cylinder portion 17 of the hinge 4 gradually acts greatly.

Therefore, in the opening / closing control mechanism A of the present embodiment, it is possible to suppress and control the opening of the door body 3 in the free section of 80 to 100 ° in which the closing mechanism A1 does not act in the past (it is possible to exert the tilt prevention function). Even if wind or the like acts in this opening state, the door body 3 may open without permission, or the door body 3 may open vigorously, causing an accident in which a user or the like is pinched, or the door. It is possible to surely eliminate the possibility that a loud impact sound is generated due to the collision of the main body 3 and that a defect such as damage or deformation of the product or part occurs.

Further, when the opening degree of the door body 3 is between 100 and 80 °, a pressing force (restoring force) acting on the advancing / retreating member 25 by a reaction force acts from the pressing plate 32 of the opening restraining mechanism 27. The anti-tilt function becomes smaller as it approaches °.

Further, when the door body 3 reaches 80 ° in the closing operation, the door body 3 can be held in a state of opening 80 ° by the attractive force of the magnet 33 as described above.

Next, when the door body 3 is closed between 80 and 0 °, the attractive force of the magnet 33 is cut off, the advancing / retreating member 25 is released, and the closing mechanism A1 acts to reduce the closing speed of the door body 3. The door body 3 can be closed by controlling it.

Therefore, in the door body opening / closing control mechanism A of the present embodiment, by providing the closing mechanism A1 and the shock absorbing mechanism A2, the door body 3 can be preferably opened / closed within the entire opening range of the door body (door body) 3. It is possible to realize a door that can be controlled, has excellent functionality, and is easy to use.

Although one embodiment of the door opening / closing control mechanism according to the present invention has been described above, the present invention is not limited to the above embodiment and can be appropriately changed without departing from the spirit of the present invention.

For example, in the present embodiment, the advancing / retreating mechanism 26 of the shock absorbing mechanism A2 is composed of the guiding member 28, the advancing / retreating member 25, and the guide member 29, but the shock absorbing mechanism A2 opens the door body (3). As long as the advancing / retreating member that advances / retreats in the vertical direction T1 according to the degree is provided, it is not necessary to particularly limit the configuration as in the present embodiment.

Further, in the present embodiment, the opening restraining mechanism 27 is a gas spring (elastic member), but the opening restraining mechanism 27 according to the present invention exerts a pressing force and a restoring force on the advancing / retreating member 25 to obtain a predetermined range. Any other elastic member such as a spring member or a rubber member may be applied as long as the opening / closing movement of the door body (3) can be suppressed by the opening degree.

Further, in the present embodiment, the magnet 33 is an opening / closing holding mechanism that attracts the pressing plate 32 to the pressing plate 32 when the desired opening degree is reached and holds the door body (3) at the desired opening degree, and the magnet 33 is the advancing / retreating member 25. Although it is assumed that the magnet 33 is attached to the upper end portion, the magnet 33 is attached to the pressing plate 32 so as to be attracted to the advancing / retreating member 25, or the magnet 33 is attached to both the upper end portion of the advancing / retreating member 25 and the pressing plate 32. The magnet 33 of the above may be attracted. Further, the opening / closing holding mechanism may use means other than a magnet as long as it is possible to apply an attractive force at a desired opening degree.

Further, as shown in FIG. 8, it is preferable to provide cover members 34 and 35 for covering the opening / closing control mechanism A of the door body and the lower cylinder portion 16 of the hinge 4 so as to improve the design.

Further, the advancing / retreating mechanism 26 of the shock absorbing mechanism A2 and the opening / retreating mechanism 27 may be unitized. In this case, for example, the shock absorbing mechanism A can be easily added to the existing door body.

Further, the shock absorbing mechanism A2 may not include the advancing / retreating member 25 and may be composed only of the opening / retreating restraining mechanism 27. In this case, the opening restraint mechanism 27 may not absorb the impact by the elastic member, but may absorb the impact by the damping member due to the viscosity of the fluid or the sliding member due to friction or sliding resistance, and the opening degree of action is limited to 80 to 100 °.
