Description

  The present invention relates to a vibration damping device, and more particularly to a vibration damping device configured to enhance vibration resistance of a structure having an opening.

For example, in a building having a car garage on the first floor, an opening for entering and exiting the car is provided on the roadway side, and the opening is opened by rotating the gate (door) that opens and closes this opening. An opening / closing mechanism that can be opened to take out or enter a car is attached (see, for example, Patent Document 1).
JP-A-7-150872

  However, since the opening is provided with a width larger than the width of the car in order to put in and out the car, for example, in the case of a building configured such that the first floor is a garage and the top is a living space, Since a pillar cannot be provided in the opening, the vibration resistance of the building may be reduced. For this reason, in a building with a structure where the first floor is a garage and the second floor or more is a living space, the strength of the walls forming the garage can be increased, or the building itself can be damped. However, if there is no room on the site, the ratio of the opening of the garage to the size of the building increases, making it difficult to improve vibration resistance.

  Accordingly, an object of the present invention is to provide a vibration damping device that solves the above-described problems.

  In order to solve the above problems, the present invention has the following means.

  The invention according to claim 1 is a door attached to be openable and closable so as to open or close an opening of a structure, a holding mechanism that is provided on the opening and holds the door in a closed position, An upper transmission member fixed to the upper part of the internal space of the door, a lower transmission member fixed to the lower part of the internal space of the door, one end connected to the upper transmission member, and the other end connected to the lower transmission member And a damper provided.

  The invention according to claim 2 is characterized in that the door is attached so as to open and close an opening of an automobile garage.

  According to the present invention, an upper transmission member, a lower transmission member, and a damper are provided in an internal space of a door that is attached to the opening of the structure so as to be opened and closed, thereby closing the door with the opening of the structure closed. It can be used as a damping wall panel that suppresses vibrations of the body, and the vibration accompanying relative displacement between the upper transmission member and the lower transmission member is absorbed by the damper to improve the vibration resistance of the structure having the opening. be able to.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a view showing a building to which an embodiment of a vibration damping device according to the present invention is applied. As shown in FIG. 1, a building (structure) 10 is a three-story building configured such that the first floor is a parking lot, the second floor, and the third floor are residences. Further, the building 10 is provided with a vibration control device 13 that operates to control vibration in the X direction at the opening 12 of the parking lot. The vibration control device 13 includes a rotary door 14 (a vibration control wall panel) that opens or closes the opening 12 and a vibration control unit 18 (in FIG. 1) provided in the internal space of the rotary door 14. (Shown by a broken line). In addition, the vibration damping device 13 is coupled to the building 10 and controls the vibration of the building 10 in the X direction when the rotary door 14 closes the opening 12.

  The rotary door 14 is rotatably supported by a frame member 20 fixed to the building 10, and is provided to open and close by a manual operation or a driving force of an opening / closing drive motor (not shown). . Then, when the vehicle is taken in and out, as shown in FIG. 2, the rotary door 14 is rotated upward and stored in the ceiling of the garage. Thereby, since the opening part 12 of a parking lot is open | released, it can take in and out a motor vehicle.

  FIG. 3 is a perspective view showing the frame member 20. As shown in FIG. 3, the frame member 20 is formed in a size corresponding to the rotary door 14, and an opening 12 that is opened and closed by the rotary door 14 is formed inside. Further, the frame member 20 is horizontally mounted between the support columns 30 and 31 erected so as to face the left and right side surfaces of the rotary door 14 and between the support columns 30 and 31 so as to oppose the upper end of the rotary door 14. And a beam 32. And the upper side holding member 34 and the lower side holding member 35 which hold | maintain the left-right side surface of the rotary door 14 are attached inside the support | pillars 30 and 31. As shown in FIG. The upper holding member 34 and the lower holding member 35 have latching grooves 34 a and 35 a that extend in the front-rear direction that coincides with the rotation direction of the rotary door 14.

  FIG. 4 is a perspective view showing the configuration of the vibration damping device 13 with the front panel removed. As shown in FIG. 4, the rotary door 14 has a configuration in which a flat panel member 42 is attached to the front and rear of a rectangular frame 40 and a space 44 is formed therein. In the space 44, the above-described vibration damping unit 18 is provided.

  The vibration control unit 18 includes an upper transmission member 50 fixed to the upper beam 40 a of the inner space 44, a lower transmission member 52 fixed to the lower beam 40 b of the inner space 44, and one end 58 a at the lower end of the upper transmission member 50. The hydraulic damper 58 (damper) is connected to the fixed connecting member 54 and the other end 58b is connected to the connecting member 56 fixed to the upper end of the lower transmission member 52.

  The hydraulic damper 58 includes a piston rod 58c and a cylinder 58d, and an operation in which a cylinder (not shown) provided at the end of the piston rod 58c is filled in the cylinder 58d in the process of sliding in the cylinder 58d. The oil passes through the throttle in the piston and generates a damping force due to the viscous resistance of the hydraulic oil. The hydraulic damper 58 of this embodiment has a damping coefficient set so that the damping force for the extension operation and the damping force for the contraction operation have the same magnitude.

  Further, an upper hooking member 60 and a lower hooking member 61 are attached to the outside of the left and right side portions 40c and 40d of the frame body 40. The upper hooking member 60 and the lower hooking member 61 correspond to the hooking grooves 34a and 35a so as to be hooked in the hooking grooves 34a and 35a of the upper holding member 34 and the lower holding member 35 described above. It has the shape latching | locking part 60a, 61a.

  Therefore, the upper holding member 34, the lower holding member 35, the upper hooking member 60, and the lower hooking member 61 constitute a holding mechanism that holds the rotary door 14 in the closed position. When the rotary door 14 is held at the closed position by the holding mechanism, vibration in the X direction is transmitted from the frame member 20 fixed to the building 10 to the frame body 40 of the rotary door 14. When relative displacement in the X direction occurs between the upper beam 40a and the lower beam 40b of the frame 40, the displacement of the upper beam 40a is transmitted to the one end 58a of the hydraulic damper 58 via the upper transmission member 50, The displacement of the beam 40 b is transmitted to the other end 58 b of the hydraulic damper 58 via the lower transmission member 52. Therefore, in the hydraulic damper 58, vibration in the X direction is transmitted, the piston rod 58c and the cylinder 58d expand and contract to generate a damping force, absorb vibration energy in the X direction, and the building 10 does not resonate. Damping so that.

  Here, a support mechanism 70 that supports the pivotable door 14 so as to be pivotable in the vertical direction will be described with reference to FIG. As shown in FIG. 5, the rotary door 14 is between a closed position (vertical state) where the opening 12 is closed by the support mechanism 70 and an open position (horizontal state) where the opening 12 is opened. It is supported so that it can rotate. The support mechanism 70 is a manual operation method, and includes an upper guide mechanism 72 that guides the movement of the upper end of the rotary door 14 and a lower assist mechanism 74 that assists the upward movement of the lower end of the rotary door 14. .

  The upper guide mechanism 72 includes a roller 82 that travels on a guide rail 80 provided on the ceiling 78 of the garage 76, and a stopper 86 when the rotary door 14 is stored in the upper space 84 of the ceiling 78.

  The lower assist mechanism 74 has one end 90 a that is pivotable and slidably coupled to the connecting portion 14 a on the back side of the pivotable door 14, and the other end 90 b of the pivot arm 90 is moved downward. And a weight 94 fixed to the other end 90 b of the swing arm 90. The swing arm 90 is rotatably supported by a rotation fulcrum 98 of a support portion 96 that protrudes to the back side of the frame member 20. Further, the position of the pivot fulcrum 98 is determined so that the swing arm 90 generates substantially the same moment as the rotational moment in the closing direction due to the weight of the pivot door 14.

  Further, the urging member 92 is formed of a coil spring or the like, and one end 92a is hooked to the other end 90b of the swing arm 90, and the other end 92b protrudes to the back side of the frame member 20. It is locked on. When the rotary door 14 is in the closed position for closing the opening 12, the swing arm 90 is also held in the vertical state. Thereby, the urging member 92 is extended in the extending direction of the swing arm 90. However, in the vertical state where the rotary door 14 is in the closed position, the direction of action of the biasing force of the biasing member 92 coincides with the pivoting fulcrum 98, so the biasing force of the biasing member 92 causes the rotary door 14 to move. Opening is prevented.

  Here, the operation of the support mechanism 70 when the rotary door 14 is opened will be described with reference to FIG. As shown in FIG. 6, when the operator holds the lower end of the rotary door 14 and rotates it in the A direction, the swing arm 90 rotates in the B direction around the rotation fulcrum 98. At that time, since the weight of the weight 94 and the urging force of the urging member 92 act as assisting force in the B direction on the other end 90b of the swing arm 90, the rotary door 14 is lifted in the A direction. The power is small.

  That is, the vibration control unit 18 is housed inside the rotary door 14, but the clockwise moment about the rotation fulcrum 98 due to the weight of the rotary door 14 and the vibration control unit 18 and the weight 94. Since the counterclockwise moment centered on the pivot fulcrum 98 due to the weight and the biasing force of the biasing member 92 is balanced with substantially the same magnitude, the force by which the operator lifts the pivotable door 14 in the A direction is relatively light. All you need is operating power.

  Further, since the roller 82 provided at the upper end of the rotary door 14 rolls on the guide rail 80 attached to the upper surface of the ceiling 78, the rotary door 14 is stored in the upper space 84 of the ceiling 78 with low friction. Can be made. At that time, a long hole 90 c provided at one end 90 a of the swing arm 90 slides while rotating with respect to the connecting pin 14 b of the connecting portion 14 a protruding to the back side of the rotary door 14. As a result, the pivotable door 14 smoothly moves from the closed position (vertical state) shown in FIG. 5 to the open position shown in FIG. 6 (horizontal state shown by a two-dot chain line in FIG. 6) to open the opening 12. To do. Therefore, the vehicle can be taken in and out from the opening 12 of the garage 76.

  Further, when moving the pivotable door 14 from the open position to the closed position, the pivotable door 14 is pivoted in the reverse procedure of the opening operation. In this case, by pulling out the pivoting door 14 stored in the upper space 84 of the ceiling 78, the pivoting door 14 pivots downward by its own weight with the roller 82 as a fulcrum, so that it can be easily closed (FIG. 5). Can be restored. At that time, the clockwise moment centered on the pivot fulcrum 98 due to the weight of the pivotable door 14 and the vibration control unit 18 and the pivot fulcrum 98 due to the weight of the weight 94 and the biasing force of the biasing member 92 are centered. Since the counterclockwise moment is balanced with substantially the same magnitude, the operator can operate with a relatively light operating force to operate the rotary door 14 in the closing direction.

  As described above, the upper latch member 60 and the latch portion 60a of the lower latch member 61 provided on the left and right side surfaces of the pivot door 14 in the process of pivoting the pivot door 14 from the open position to the closed position. , 61 a are fitted in the retaining grooves 34 a, 35 a of the upper holding member 34 and the lower holding member 35 provided inside the frame member 20. As a result, the pivotable door 14 is configured such that the upper holding member 34 and the lower holding member 35 provided on the left and right inner sides of the frame member 20 via the upper hooking member 60 and the lower hooking member 61 arranged on the left and right. And is held in a state where the operation in the X direction is strongly regulated.

  Therefore, the pivotable door 14 is integrated with the frame member 20 of the building 10 and is held in a fixed state in which vibration in the X direction is transmitted. Therefore, when vibration in the X direction is input to the building 10, the vibration control unit 18 built in the rotary door 14 performs a vibration control operation. Therefore, in the building 10 having the opening 12, the damping unit 18 performs a damping operation by closing the rotary door 14, and thus the damping performance of the building is improved by the damping operation of the hydraulic damper 58.

  In addition, in the said Example, although the structure which incorporated the damping unit 18 in the rotary door 14 which opens and closes the opening part 12 of a garage was demonstrated as an example, it is not restricted to this, For example, of the warehouse which has an opening part It is also possible to incorporate the vibration control unit 18 in the open / close door.

  Moreover, although the said Example demonstrated to an example the building where the garage was provided in the 1st floor of a three-story building, this invention is also applied to the building with the space (storage etc.) where the 1st floor other than this is not a parking lot. Of course, can be applied.

  Furthermore, in the said Example, although the structure which rotates the rotary door 14 to an up-down direction and was accommodated in the upper space of a garage was demonstrated as an example, it is not restricted to this, A door is rotated to the left-right direction, Of course, the present invention can also be applied to a door that is housed in a lateral space and opened.

  In the above embodiment, a hydraulic damper is used as the damper. However, the present invention is not limited to this, and a friction damper, a gas spring damper, a high viscoelastic rubber, etc. In short, the damping element acting as a damper may be freely selected. Then, a desired characteristic may be obtained by combining these portions having good attenuation characteristics.

  Furthermore, although the thing using a coil spring was shown as the urging | biasing member 92 of the door which assists an operator, it is not restricted to this, For example, a tension type gas spring etc. can also be used as an urging | biasing element.
