[Problems to be solved by the invention]
In a configuration in which the door main body is opened and closed by swinging as in the related art, there is a possibility that the head or the like may be hit against the door main body or the like in a state where the door main body is opened to cause an injury. Alternatively, when the storage is provided near the ceiling, there is a disadvantage that opening the door body interferes with the lighting equipment and the like, so that the arrangement of the equipment is not effective. That is, in the conventional swing type door opening / closing structure, a large space is required on the front side of the storage.
Moreover, in the structure in which the two door bodies are slid and opened and closed, the depth of the storage body is reduced by the rail groove, and even if one of the door bodies is fully opened, the effective opening width of the storage is more than half of the full width. Further, there is a disadvantage that the doors cannot be opened at the same time because the two door bodies cannot be opened at the same time.
Further, the conventional door opening / closing structure that opens / closes by swinging operation is configured by a dedicated hinge or the like corresponding to the size of the storage, and is disposed at predetermined upper and lower positions on the back surface of the door body. Therefore, the hinge could not be changed to a different position, or the hinge could not be used. Further, there is a drawback that even if it is desired to replace the door main body with one having a different height, it is not possible to cope with it, and it is necessary to replace the entire storage main body.
Conventionally, guides (hinges and the like) are provided at upper and lower positions of the door body, respectively, and these are configured to be tuned by a vertical connecting rod. However, if the connecting rod becomes longer, Its responsiveness is inferior, and it has the disadvantage that its configuration is complicated and its appearance is poor.
[0005]
Therefore, the present invention provides a storage container in which the opened door body does not obstruct the storage container in front of the storage container, and the opening of the storage container can be completely opened so that storage items can be easily taken in and out, and the operability is good. It is an object to provide a door opening and closing structure.

Note that the second link arm 6 interferes with the side wall 14 of the storage main body 1 when the door body 2 is pulled out to the front as the swinging out angle of the door body 2 exceeds 90 ° as shown in FIG. It has a curved shape in order to prevent it from occurring.
[0016]
Further, the third link arms 7 are linear link arm plates which are disposed between the upper edge and the lower edge of the first link arm 5 in the form of a plate and are paired up and down to form a pair. The part side is pivotally attached to the mounting portions 17, 17, and the distal end side is pivotally attached to the guide member 18.
The parallel link mechanism 3 has three link arms, one of which (the second link arm 6) is disposed at the other two upper and lower positions at different heights, and has a compact structure. Try not to interfere.
[0017]
According to this configuration, as shown in FIGS. 7 to 9, all the three link arms in plan view do not line up linearly within the range of the swing-out angle of the door body 2, so that the parallel link is always provided. The mechanism section 3 can maintain a parallelogram having a wide vertical axis center interval P. For this reason, the rigidity of the support tool G is high, and the load of the cantilevered door body 2 can be stably held and smoothly opened and closed. As described above, since the configuration can always have rigidity, the swing pulling-out angle of the door main body 2 can exceed 90 °. Therefore, the door main body 2 can be positioned largely laterally outward from the opening 10 of the storage main body 1, and the opening 10 can be widely opened.
[0018]
As shown in FIG. 9, a stopper portion 30 is formed at a predetermined position on the base end side of one of the above-mentioned three types of link arms (the third link arm 7 in the present invention). Abuts against the base member 16 fixed to the side wall 14, the front draw-out position of the door body 2 can be determined. This swing-out angle matches the swing angle of each link arm, and is 0 ° when the door body 2 is fully closed. The swing angle can be arbitrarily set beyond 90 °, but is set to about 0 ° for fully closed to about 135 ° for fully open.
[0019]
Next, the linear guide mechanism 4 will be described. As shown in FIGS. 5 and 6, the linear guide mechanism 4 is a pair of upper and lower horizontal hollow or solid members attached to the back surface 2a of the door body 2. And a pair of upper and lower cylindrical linear bearing members (linear bearings) connected to the door body 2 side (tip end side) of the parallel link mechanism unit 3 and externally holding the round bar rail member 8. 9). Then, the round bar rail member 8 is guided by the linear bearing member 9, and the door main body 2 is slidable on the distal end side of the parallel link mechanism 3 as shown in FIGS. 9 and 10.
[0020]
The linear round bar rail members 8, 8 are fixed at both end sides by fixing jigs 19, 19 connected to the back surface 2a of the door body 2 by screws or the like. Also serve as stoppers for the start and end points of the stroke of the slide movement.
The cylindrical linear bearing member 9 is a cylindrical bearing member having a plurality of rolling bearings that can smoothly roll in the longitudinal direction of the round bar rail member 8 on the inner peripheral surface. A plurality of locations can be contacted in the surface circumferential direction. The cylindrical linear bearing member 9 is connected to a guide member 18 on the distal end side of the parallel link mechanism 3. That is, the door main body 2 is connected to the distal end of the parallel link mechanism 3 whose base end is connected to the storage main body 1 with the linear guide mechanism 4 interposed therebetween.
[0021]
Further, as shown in the plan explanatory views of FIGS. 5 and 6 and FIGS. 11, 12 and 13, the swing linear support G is a vertical guide shaft member attached to the back surface 2 a of the door body 2. 11 is provided. The guide shaft member 11 is formed on a part of a fixing jig 19 on the right side in front view (on the side close to the door body 2 in a fully closed state). Further, the swing linear support G includes a swing guide member 13 disposed at a predetermined position of the first link arm 5. The guide shaft member 11 is guided into the swing guide member 13 when the door body 2 swings, and is guided only when the door body 2 is pulled out by the parallel link mechanism 3. An arc-shaped guide groove 12 that allows the shaft member 11 to be detached is formed. That is, the guide shaft member 11 and the swing guide member 13 function as a slide stopper for the linear guide mechanism 4. An opening / entrance 29 is formed at one end of the guide groove 12, and the guide shaft member 11 passes through the opening / entrance 29.
[0022]
The two guide shaft members 11 on the side of the door main body 2 are arranged on the same vertical line at a position substantially at the center of the support tool G, extend in the direction in which they face each other, and have a predetermined interval between their tips. . The swing guide member 13 on the side of the parallel link mechanism 3 has arc-shaped guide grooves 12 on both sides of the upper and lower surfaces so that the pair of guide shaft members 11 is inserted. The guide shaft members 11, 11 are formed in an arc shape about the second vertical axis 22, and move around the second vertical axis 22 in the guide grooves 12, 12 according to the swinging operation of the door body 2. That is, the guide shaft member 11 is inserted into the guide groove 12 while the door body 2 performs the swing-out operation, so that the door body 2 cannot slide.
[0023]
The parallel link mechanism portion 3 is a tension spring member that resiliently urges the door body 2 in the closing direction when the door body 2 approaches the fully closed state, or in the front drawing direction when approaching the near-drawing state. 27 is provided between the mounting portion 17 of the base member 16 and the guide member 18. As shown in FIG. 7, when the door body 2 approaches the fully closed state, the center line of the spring member 27 is closer to the door body closing direction than the axis of the link arms 5, 6, and 7 (the storage body body). When the door body 2 is pulled out to the front side and pulled beyond a certain point (dead point), the space between the mounting portion 17 and the guide member 18 is pulled and swung in the closing direction. As shown in the figure, the center line of the spring member 27 is disposed closer to the door main body opening direction than one of the axes of the link arms 5, 6, and 7, and the space between the mounting portion 17 and the guide member 18 is pulled. It is configured to swing in the opening direction.
[0024]
Next, the action (operation) of the swing linear support G when the door body 2 shifts from the fully closed state to the fully opened state will be described. Reference numeral 28 denotes a handle attached to the front surface 2b of the door body 2.
In the state shown in FIG. 7, the door body 2 is held in the fully closed state by the elastic force of the spring member 27, does not open without permission, and does not move. In this state, the door body 2 is at the rear position. When the user pulls the door body 2 toward the user against the elastic force of the spring member 27 by holding the handle 28, the door body 2 swings in the direction of arrow a, and the door swinging state shown in FIG. , The state shown in FIG. In this state, the door body 2 is at the front position, and the distal end side of the parallel link mechanism 3 is located on the right side of the door body 2 when viewed from the front. Further, since the spring member 27 urges the door main body 2 in the opening direction, the door main body 2 does not arbitrarily close in the closing direction. Further, the stopper 30 provided on a part of the third link arm 7 of the parallel link mechanism 3 abuts on the fixed base member 16 so that the door main body 2 is prevented from swinging more than necessary. ing.
[0025]
Further, at the time of this swinging operation, the guide shaft member 11 on the side of the door body 2 swings along with the swinging movement of the door body 2 as shown in FIGS. Since the door body 2 moves along the arc-shaped guide groove 12 of the member 13, the door main body 2 does not slide by the linear guide mechanism 4, and is brought into the front drawer state.
In other words, the door main body 2 can be swung to the rear opening left side in the fully closed state and the front right side in the front drawing state with respect to the vertical opening surface of the storage main body 1 while maintaining the parallel state. Can be.
[0026]
Thereafter, when the door body 2 is further slid to the right (in the direction of arrow b), the distal end side of the parallel link mechanism 3 is located on the left side of the door body 2 in front view as shown in FIG. Then, the door body 2 is fully opened.
Further, when the door body 2 is pulled out to the front, the guide shaft member 11 on the door body 2 side is located at the opening / entrance portion 29 of the guide groove 12 of the swing guide member 13 as shown in FIG. As shown in FIG. 13, when the door body 2 starts the sliding operation, the guide shaft member 11 passes through the opening / entrance portion 29 and is disengaged from the swing guide member 13, and the door body 2 can linearly move laterally. .
Note that the operation of shifting the door main body 2 from the open state to the closed state may be performed through a process reverse to the above.
[0027]
【The invention's effect】
The present invention has the following effects by the above configuration.
[0028]
(According to claim 1) The space required for opening and closing the door main body 2 is small, and the door main body 2 does not greatly protrude in the open state, so that it does not become a hindrance, and there is a possibility of interference with lighting equipment and the like. Absent. That is, as shown in FIG. 1, the protrusion dimension D is small, and no space is required for opening and closing the door body 2, and the storage can be installed at any place. Further, since the door body 2 is once pulled out from the storage main body 1 and slid, the opening 10 of the storage main body 1 can be largely opened, so that it is easy to take in and out the storage items, and the storage part is effectively used. it can.
Since there is only one swing linear support G, installation is possible without being affected by the shape and size of the door body 2. Further, the mounting position of the door main body 2 can be easily adjusted vertically and horizontally by adjusting only one swing linear support G.
[0029]
(According to claim 2) Since the oscillating linear support G is formed in a vertically symmetrical shape, it can be mounted on the left and right sides independently (the door can be opened and closed by the same mechanism), and the left and right opening and closing can be used. There is no need to distinguish between opening and closing, and there is no need for installation.
(According to claim 3) Even if the door main body 2 is swung and two of the three link arms overlap in plan view, the rigidity of the swing linear support G is maintained by the remaining one link arm. Therefore, the door body 2 can be stably held at all angles. Therefore, the swing angle of the door body 2 can be further increased beyond 90 °, and the opening degree of the opening 10 can be increased.
[0030]
(According to claim 4) The number of the swing linear supports G is one, and even if the center of gravity of the door body 2 is not on the linear guide mechanism 4, the operation can be smoothly performed without rattling. Further, the door main body 2 can be prevented from hitting one of the pair of upper and lower round bar rail members 8 at one side, so that accuracy can be easily obtained at the time of assembling, and the assembling becomes easy. Further, by changing the length of the round bar rail member 8, the moving distance of the door body 2 to be slid can be easily changed.
According to the fifth aspect, the swinging operation of the door body 2 can be stabilized. The door main body 2 can be configured so that it cannot slide to the side unless it is once swung to the predetermined front drawer state, thereby preventing erroneous operation and improving operability.
