JP 2005-133330 A

  In the above conventional door opening and closing device, the four-bar link mechanism constituted by the housing side mounting member, the door side mounting member, the first link and the second link is a parallel link mechanism. Therefore, the door maintains the posture in the closed position, that is, the posture standing up and down regardless of the movement position. For this reason, for example, when the door is moved up and down in the vertical direction, when the door moves to the open position, the upper end portion of the door largely protrudes upward from the housing, and the door is opened and closed in the left-right direction. In such a case, there is a problem that the left and right end portions of the door protrude greatly from the housing in the left-right direction.

In order to solve the above-mentioned problem, a first aspect of the present invention includes a box-shaped housing having an open front portion, and a door provided on the housing so as to be opened and closed via a door opening / closing device. The door is positioned along the front surface of the housing and closes the opening of the housing, and the entire door is positioned on one end side of the housing from the door. In the storage device that is movable between the open position that opens the opening of the housing located on the other end side, when the door is located at the open position, one end of the door is the other end. Further, the door is inclined so as to be largely separated forward from the front surface portion of the housing.
In this case, when the door is located at the closed position, the one end of the door that faces the one end of the housing is rotated from the closed position toward the open position to a predetermined intermediate position. Is moved from the other end side of the casing toward the one end side so as to be separated from the casing forward, and while the door is rotated from the intermediate position to the open position, the casing is It is desirable that the head is moved from the one end side to the other end side so as to be separated from the casing forward.
In order to solve the above-mentioned problem, the second aspect of the present invention is a case-side attachment member attached to a box-like case having an open front portion and a door that opens and closes the opening of the case. A door-side mounting member and one end of each of the door-side mounting members is pivotally connected to the housing-side mounting member around first and second rotating shafts that are parallel to each other, and the other end is connected to the first and second ends. A first link and a second link pivotally connected to the door-side mounting member about a third and a fourth rotation axis parallel to the second rotation axis, and the first and second rotation axes. Is disposed at one end portion that is off the center of the opening of the housing, and the door is opposed to the other end portion of the housing when the third and fourth rotating shafts are located at the closed position. The first rotation shaft is disposed closer to one end of the housing than the second rotation shaft, and In the door opening and closing device in which three rotation shafts are arranged closer to one end side of the door than the fourth rotation shaft, four doors including the housing side mounting member, the door side mounting member, the first link, and the second link. A condition that when the node link mechanism rotates the door from the closed position to the open position, the moving distance to the front of the third rotating shaft is longer than the moving distance to the front of the fourth rotating shaft. It is characterized by being comprised so that it may satisfy | fill.
In this case, the four-bar linkage mechanism is configured to satisfy a condition that the third rotation shaft is always positioned forward of the fourth rotation shaft regardless of the rotation position of the door. desirable.
The length obtained by adding the distance between the first and second rotation axes and the distance between the first and third rotation axes is equal to the distance between the third and fourth rotation axes and the first. 2 and the distance between the fourth axes is set longer than the length, and the second pivot shaft and the fourth pivot are set at a predetermined intermediate position between the closed position and the open position. The four-bar linkage mechanism is preferably configured such that the shaft and the third rotation shaft are sequentially aligned on a straight line.

According to the first aspect of the invention having the above-described characteristic configuration, when the door is positioned at the open position, that is, when the door is positioned at one end of the casing and the other end of the opening of the casing is opened. Since the door is inclined so that one end of the door is farther forward from the front of the housing than the other end, one end of the door in the direction from the other end of the housing to the one end The amount of protrusion protruding from the housing can be reduced.
According to the second aspect of the present invention having the above-described characteristic configuration, when the door moves from the closed position to the open position, the movement distance of the third rotation shaft to the front is the forward movement of the fourth rotation shaft. Since the door is longer than the distance, the door standing in the closed position is inclined so that one end of the door is farther away from the front of the housing than the other end in the open position. Therefore, similarly to the invention according to the first aspect, it is possible to reduce the protruding amount of the one end portion of the door from the housing.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 12 attached herewith show an embodiment of a storage device according to the present invention. As shown in FIGS. 1 to 6, the storage device 1 of this embodiment includes a housing 2, a door 3, and a door opening / closing device 4.

  The casing 2 has a rectangular parallelepiped box shape that is vertically long, and an opening 2b is formed on the front surface 2a thereof. The door 3 has a flat plate shape, and the left and right widths and the upper and lower lengths thereof are substantially the same as the width and length of the front surface 2 a of the housing 2. The door 3 is connected to the housing 2 via a door opening / closing device 4 so as to be movable between a closed position shown in FIG. 1 and an open position shown in FIG. When the door 3 is in the closed position, as shown in FIG. 1, the door 3 stands up and down along the front surface 2 a of the housing 2, and the rear surface 3 a is connected to the front surface 2 a of the housing 2. The opening 2b of the housing 2 is closed by making it face each other. When the door 3 is located at the open position, as shown in FIG. 5, the entire door 3 is located on the upper end side (one end side) from the center in the vertical direction of the housing 2. Thereby, the door 3 is opening the opening part 2b below it (other end side). Moreover, when the door 3 is located at the open position, the door 3 is inclined with respect to the front surface 2a of the housing 2 so that the upper end portion of the door 3 is largely separated from the lower end portion.

  The door opening / closing device 4 is for moving the door 3 from the closed position to the open position as described above, and one door opening / closing device 4 is provided between the left and right sides of the housing 2 and the door 3. Since the two door opening and closing devices 4 and 4 provided on the left and right are configured symmetrically, only one door opening and closing device will be described. The door opening / closing device 4 includes a housing side mounting member 41, a door side mounting member 42, a first link 43 and a second link 44.

  The housing side attachment member 41 is made of a metal plate, and is attached to either the left or right inner surface of the housing 2 at a location close to the opening 2b.

  One end of the first and second links 43 and 44 (hereinafter referred to as a base end, and the other end of the first and second links 43 and 44 is referred to as a distal end) of the housing side mounting member 41. The first and second rotation shafts 45 and 46 are horizontally connected with their axis lines in the left-right direction so as to be rotatable. The distal ends of the first and second links 43 and 44 rotate through the third and fourth rotation shafts 47 and 48 that are parallel to the first and second rotation shafts 45 and 46 with respect to the door-side mounting member 42. Connected as possible. Accordingly, the four-link mechanism R is configured by the housing side mounting member 41, the door side mounting member 42, and the first and second links 43 and 44. Needless to say, the four-bar linkage mechanism R uses a case-side attachment member 41 fixed to the case 2 as a fixed system.

  The door-side attachment member 42 is detachably attached to the back surface 3 a of the door 3 via the connector 6. The connecting device 6 is a known device used for this kind of door opening and closing device, slide hinge, and the like, and since it is not the gist of the present invention, its detailed description is omitted, but the mounting position of the door side mounting member 42 with respect to the door Can be finely adjusted in the up / down / left / right and front / rear directions. Thereby, the position of the door 3 in the vertical and horizontal directions and the front and rear direction with respect to the housing 2 can be finely adjusted.

  A gas spring 7 is provided between the housing side attachment member 41 and the first link 43. One end of the gas spring 7 is rotatably connected to the housing side mounting member 41 via a shaft 49 parallel to the first rotation shaft 45. The other end of the gas spring 7 is rotatably connected to the movable member 8 provided on the first link 43 via a shaft 50 parallel to the shaft 49. The gas spring 7 rotates the first link 43 in the clockwise direction in FIG. 1 when the door 3 is located between the closed position and a predetermined neutral position separated from the open position by a predetermined distance. The door 3 is biased from the open position side to the closed position side. Moreover, between the closed position and the neutral position, the door 3 tends to move from the open position side to the closed position side by its own weight. Therefore, when the door 3 is positioned between the closed position and the neutral position, the door 3 automatically moves to the closed position.

  When the door 3 is positioned at the neutral position, the shafts 49 and 50 and the first rotation shaft 45 are aligned on a straight line. For this reason, the urging force of the gas spring 7 does not act on the first link 43 as a rotating urging force. When the door 3 crosses the neutral position from the closed position side toward the open position side, the gas spring 7 urges the first link 43 to rotate counterclockwise in FIG. 2 and pushes the door 3 toward the open position side. To force. Here, the urging force of the gas spring 7 that urges the door 3 toward the open position closes the door 3 by its own weight until the door 3 reaches a predetermined equilibrium position from the neutral position toward the open position. Weaker than the force to move to the position side. Therefore, it is necessary to manually move the door 3 to the open position side until the equilibrium position. On the other hand, when the door 3 exceeds the equilibrium position from the closed position side to the open position side, the urging force of the gas spring 7 that urges the door 3 to the open position side is stronger than the force toward the closed position side by the dead weight of the door 3. Become. Therefore, when the door 3 exceeds the equilibrium position, it automatically moves to the open position.

  The position of the movable member 8 can be adjusted in the direction connecting the first rotation shaft 45 and the shaft 50, and by adjusting the position of the movable member 8, the gas spring 7 can be rotated with respect to the first link 43. The urging force for urging the door 3 from the closed position side to the open position side can be adjusted by adjusting the urging force.

  The gas spring 7 may be provided between the housing side mounting member 41 and the second link 44. Further, instead of the gas spring 7, other urging means such as a tension coil spring or a compression coil spring may be used.

  As shown in FIG. 9, both ends of the reinforcing plate 9 are attached to the first rotation shaft 45 and the second rotation shaft 46, respectively. The frame-side mounting member 41 is reinforced by the reinforcing plate 9. As shown in FIG. 11, the decorative cover 10 is attached to the housing-side attachment member 41. The decorative cover 10 shields the housing side attachment member 41, the base ends of the first and second links 43 and 44, the gas spring 7 and the reinforcing plate 9 from the outside as much as possible.

  A contact member 31 is provided at the lower end of the door 3. When the door 3 moves from the open position side to the closed position, the contact member 31 abuts against a stopper (not shown) provided on the housing 2. Thereby, the closed position of the door 3 is determined. On the other hand, as shown in FIG. 5, when the door 3 moves from the closed position side to the open position, the contact member 31 hits the second link 44. Thereby, the open position of the door 3 is determined.

  As shown in FIG. 12, a bracket 11 is fixed to the first link 43, and a damper mechanism 12 is provided on the bracket 11. The damper mechanism 12 includes a cylinder 12a, and a rod 12b in which a base end portion is accommodated in the cylinder 12a so as to be movable in the axial direction, and a distal end portion protrudes from the cylinder 12a. The damper mechanism 12 has a function of suppressing the moving speed to a low speed when the rod 12b moves relative to the cylinder 12a.

  The cylinder 12a of the damper mechanism 12 is provided on the bracket 11 so as to be movable in the axial direction. On the other hand, the position of the rod 12b is fixed to the bracket 11. Therefore, in the damper mechanism 12, the cylinder 12a actually moves relative to the rod 12b. As shown in FIG. 1, when the door 3 moves from the open position side to the closed position side and reaches a position in front of the closed position by a predetermined distance, the abutting portion provided on the housing side mounting member 41 It hits 41a. As a result, the cylinder 12a moves so that the rod 12b relatively enters the cylinder 12a. Therefore, the moving speed of the door 3 to the closed position side is suppressed to a low speed until the door 3 reaches the closed position after the cylinder 12a hits the contact portion 41a. Therefore, the contact member 31 does not collide with the stopper of the housing 2 at a high speed, and the occurrence of an impact due to the collision can be prevented. Further, as shown in FIG. 4, when the door 3 moves from the closed position side to the open position side and reaches a position a short distance from the open position, the cylinder 12a is brought into contact with the second link 44. It strikes against the portion 44a (see FIGS. 7 to 10). As a result, the cylinder 12a moves so that the rod 12b relatively enters the cylinder 12a. Therefore, the moving speed of the door 3 to the open position side is suppressed to a low speed until the door 3 reaches the open position after the cylinder 12a hits the contact portion 44a. Therefore, the contact member 31 does not collide with the second link 44 at a high speed, and the occurrence of an impact due to the collision can be prevented.

  The four-bar linkage mechanism R including the housing side attachment member 41, the door side attachment member 42, the first link 43, and the second link 44 has the following configuration. That is, the first rotation shaft 45 is disposed above the second rotation shaft 46, and the third rotation shaft 47 is positioned above the fourth rotation shaft 48 regardless of the position of the door 3. Are arranged as follows. Accordingly, the first link 43 is always located above the second link 44 regardless of the position of the door 3. In addition, the first and second rotation shafts 45 and 46 are disposed on the upper end side from the center in the vertical direction of the housing 2, and the third and fourth rotation shafts 47 and 48 are located at the closed position. The door 3 is disposed below the center in the vertical direction. Accordingly, the distance between the first rotation shaft 45 and the third rotation shaft 47 and the distance between the second rotation shaft 46 and the fourth rotation shaft 48 are shortened, and the door 3 is moved. When the door 3 is in the open position, the lower end of the door 3 can be positioned as high as possible.

In the four-bar linkage mechanism R, the third rotation shaft 47 is always located above the fourth rotation shaft 48 while the door 3 moves from the closed position to the open position, and the third rotation shaft is interposed therebetween. 47 is configured to satisfy the condition that it largely moves forward from the fourth rotation shaft 48. In order to satisfy such a condition, a four-bar linkage mechanism excluding parallel links is employed as the four-bar linkage mechanism R. That is, as shown in FIG. 1, the center-to-center distance between the first rotation shaft 45 and the second rotation shaft 46 is the first inter-axis distance L1, and the first rotation shaft 45 and the third rotation shaft. The center-to-center distance between the second rotation shaft 46 and the fourth rotation shaft 48 is the third center-to-axis distance L3. When the center-to-center distance between the shaft 47 and the fourth rotating shaft 48 is the fourth inter-axis distance L4,
L1 ≠ L4
L2 ≠ L3
The first to fourth inter-axis distances L1 to L4 are determined so as to satisfy any one of

Furthermore, in this embodiment, the four-bar linkage mechanism R is configured to satisfy the following conditions.
L1> L4
L2> L3
L1 + L2> L3 + L4
Moreover, the distances L2 and L3 between the second and third axes are set to be larger than the distances L1 and L4 between the first and fourth axes. Further, when the door 3 is located at the closed position, the distance between the first and second rotation shafts 45 and 46 in the front-rear direction and the vertical direction is the front and rear of the third and fourth rotation shafts 47 and 48, respectively. It is longer than the distance in the direction and the vertical direction. Further, when the door 3 is in the closed position, the first rotation shaft 45 is located slightly behind the third rotation shaft 47 and the second rotation shaft 46 is slightly behind the fourth rotation shaft 48. Is located.

  When the door 3 is connected to the housing 2 by the door opening / closing device 4 having the above-described configuration, as shown in FIGS. 1 to 6, the third operation is performed as the door 3 moves from the closed position toward the open position. The moving shaft 47 moves forward more largely than the fourth rotating shaft 48. In other words, the distance in the front-rear direction between the third rotation shaft 47 and the fourth rotation shaft 48 increases as the door 3 moves from the closed position to the open position. As a result, the door 3 is inclined so that the upper end portion thereof is largely separated from the front surface 2a of the housing 2 forward from the lower end portion. In addition, the inclination angle increases as the door 3 rotates from the closed position to the open position.

  When the door 3 further moves to the open position side and reaches a predetermined intermediate position shown in FIG. 4, the second, fourth, and third rotating shafts 46, 48, 47 are aligned in a straight line. While the door 3 moves from the closed position to the intermediate position, the upper end of the door 3 moves upward while moving forward. However, after that, when the door 3 further moves to the open position side, the fourth rotation shaft 48 is positioned closer to the first rotation shaft 45 than the line connecting the second rotation shaft 46 and the third rotation shaft 47. Thus, the upper end of the door 3 moves downward while moving forward as the door 3 moves toward the open position. As a result, the increase rate of the inclination angle of the door 3 with respect to the fixed rotation angle of the first and second links 43 and 44 is increased. Therefore, the inclination angle of the door 3 when the door 3 reaches the open position can be increased.

Thus, when the door 3 moves to the open position, the door 3 is inclined, so that the protrusion amount of the upper end portion of the door 3 protruding upward from the housing 2 can be kept small.

In addition, this invention is not limited to said embodiment, In the range which does not deviate from the summary, it can change suitably.
For example, in the above-described embodiment, when the door 3 moves from the closed position to the open position, the movement distance of the third rotation shaft 47 to the front is the movement distance of the fourth rotation shaft 48 to the front. Although it is set so as to be always longer, the total moving distance of the third rotating shaft 47 to the front when the door 3 reaches the open position is the total moving distance of the fourth rotating shaft 48 to the front. As long as the condition of longer is satisfied, while the door moves from the closed position to the open position by a predetermined distance, the door 3 moves forward from the third rotation shaft 47 accompanying the movement from the closed position to the open position side. The moving distance may be shorter than the moving distance of the fourth rotating shaft 48 forward.

  The present invention is applied to a housing device that has a relatively large space in front of the opening of the housing, but has a narrow space on the side of the housing, so that the opening of the housing is widened. be able to.
