Description

The present invention relates to door opening and closing instrumentation 置及 beauty accommodating furniture as can polymerize on the front surface of the adjacent door is rotated without Seridasa utmost forward the door with a simple configuration.

  Conventionally, as this kind of door opening and closing device, a device provided with a hinge h as shown in FIGS. 10A and 10B is generally used. This door is inverted by rotating the shaft part c sufficiently forward from the front surface of the door a through the arm b and rotating approximately 180 ° from the closed position as shown in FIG. a is taken out further forward from the shaft portion c via the arm b, so that the door a does not interfere with the adjacent door a, the shaft portion c of the door a, or the like. For this reason, the amount of protrusion of the shaft portion a is large, and a large gap δ is generated between the facing surfaces of the door a rotated 180 ° and the adjacent door a, thereby deteriorating the appearance and quality, and the inconvenience such as narrowing the front operating space. It was accompanied by. Although not shown, even when the door a is rotated 90 °, the shaft c protrudes forward through the arm b, so that the entire door a protrudes forward, and the front operating space is further greatly impaired. It was supposed to be.

In order to eliminate such inconvenience, for example, Patent Document 1 and the like use a two-stage hinge (bringing hinge). This take-out hinge rotates the door 90 ° through the first movable plate, and at this time, the second movable plate is moved to the first movable plate through the shaft brought out to the front end side of the first movable plate. Is further rotated by 90 °, so that the door can be rotated by 180 °. Then, the door is closely arranged to face the adjacent door at the time of 180 ° rotation, and a state in which the door does not protrude forward as much as possible at the time of 90 ° rotation is realized.
Japanese Utility Model Publication No. 60-6133

  However, when such a take-out hinge is used, the number of parts increases and the structure becomes complicated. In addition, the operation is impaired in two stages because it operates in two stages. Therefore, it is desired to realize a door opening / closing device that can be configured more simply and can be moved to a 90 ° rotation position or a 180 ° rotation position without causing the door to protrude as much as possible under continuous operability. By the way.

  An object of the present invention is to provide such a door opening and closing device.

  In order to achieve this object, the present invention takes the following measures.

That is, the door opening and closing device of the present invention forms a hinge mechanism by slightly projecting the shaft part forward from the front surface of the door between the housing and the door, and is adjacent to the door side when rotated approximately 180 °. An interference avoidance part that avoids interference with the shaft part that slightly protrudes forward from the front surface of the door is provided , and the shaft part is provided substantially on the edge of the suspension side along the width direction of the door. and said that you are.

When configured in this way, when the door is rotated approximately 180 °, interference with the shaft portion of the adjacent door is avoided in the interference avoidance portion, so the amount of protrusion of the shaft portion from the door is kept to a slight amount. The front surface of the inverted door can be placed in close proximity to the front surface of the adjacent door. For this reason, without using a two-stage hinge or the like, it is possible to maintain a good appearance and tone by close contact between the door rotated 180 ° and the adjacent door, and to reduce the operating space in the front as much as possible. . In addition, even when rotated by 90 °, since the shaft portion is located at a position close to the housing, the amount of forward protrusion can be suppressed, and an operating space can be secured as much as possible.
In addition, since the shaft part is located substantially on the edge of the suspension side along the width direction of the door, when the door rotates, the radius of rotation from the shaft part of the edge of the suspension side is very small. It is possible to avoid the edge portion from interfering with the housing as much as possible. This point is also effective for the purpose of suppressing the unnecessary protrusion of the door when the shaft portion is rotated as much as possible by rotating the shaft portion by 90 °.

  In order to keep the protruding amount of the shaft part as small as possible, the shaft part is provided in close proximity to the door side so that at least a part thereof is located within the thickness of the door, in other words, the shaft part. Is preferably provided at substantially the same position as the front surface of the door.

  As a concrete embodiment of the interference avoiding part, the interference avoiding part is an open space formed by a recess, a notch, a slit or other form existing in the thickness dimension of the door, and the door reversed by the rotation is adjacent. It is preferable to receive the shaft portion of the hinge mechanism adjacent to the open space provided in the interference avoidance portion of the rotated door when facing in close proximity to the front surface of the door.

  In order to open the space in the housing more widely and make it easier to put in and take out articles, the shaft portion is located at a position corresponding to the thickness of the side plate of the housing in front of the side plate. It is desirable to displace further to the outer surface side of the side plate than the thickness center of the side plate.

  A hinge mechanism that is simple and easy to install includes a fixed member that is fixed to the housing and a movable member that is fixed to the door. The fixed member and the movable member have a bulging portion from the front to the front. It is preferable that the shaft portion is formed by connecting each bulging portion with a shaft.

  In this case, in order to appropriately configure the interference avoiding portion, the movable member and the fixed member are overlapped when closed, and when the movable member is pulled out, the bulging portion of the movable member changes the overlapping position with the bulging portion of the fixed member. The part of the movable member where the fixed member is overlapped is released by moving away from the fixed member, and functions as an interference avoiding unit that avoids interference with the shaft portion constituting the adjacent hinge mechanism. Is reasonable.

  In order to properly incorporate the hinge mechanism into the door, a fixed part and a movable member are arranged so that a missing part is provided on the door suspension side, and when the door is closed, the missing part is filled to complement the outline line of the door. It is convenient to do.

  Since the above door opening and closing device has the above-described configuration, it can be extremely useful when applied to storage furniture in which a pair of doors are attached to a housing in a double door state.

The present invention can be configured more simply than the two-stage hinge or the like by the above-described configuration, and the 90 ° rotational position or the like without causing the door to protrude forward as much as possible under continuous operability. It is possible to provide an excellent door opening / closing device that can be moved to a 180 ° rotation position. In addition to this, if the shaft part is positioned in front of the side plate of the housing, the door can be almost used even when the housing is placed near the wall and the door is opened or when the door is opened simultaneously from an adjacent housing. The drawer can be opened 90 degrees, and even when a drawer or the like is accommodated in the housing, the drawer can be taken in and out without inconvenience.
In addition, since the shaft part is located substantially on the edge of the suspension side along the width direction of the door, when the door rotates, the radius of rotation from the shaft part of the edge of the suspension side is very small. It is possible to avoid the edge portion from interfering with the housing as much as possible. This point is also effective for the purpose of suppressing the unnecessary protrusion of the door when the shaft portion is rotated as much as possible by rotating the shaft portion by 90 °.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows a storage furniture 1 to which the door opening / closing device A of this embodiment is applied. In this storage furniture, a pair of doors 15 are opened in a door-opening state via the door opening / closing device A at a position for opening and closing the storage space of the housing 1z constituted by the left and right side plates 11, top plate 12, bottom plate 13 and back plate 14. The door opening and closing device A is provided between the vicinity of the edge 15 a on the hanging side of the door 15 and the top plate 12, and between the vicinity of the edge 15 a on the hanging side of the door 15 and the bottom plate 13. The hinge mechanisms a1 and a2 are arranged respectively.

  FIG. 2 shows a state in which the pair of storage furniture 1 is adjacent to each other, the hinge mechanism a1 constituting the door opening / closing device A of the left storage furniture 1 is assembled, and the door opening / closing device A of the right storage furniture 1 is configured. The hinge mechanism a1 is shown in a partially disassembled state. The hinge mechanism a1 is configured by connecting a fixed member 2 attached to the housing 1z side and a movable member 3 attached to the door 15 side via a shaft 4x.

  The fixing member 2 has an attachment piece 22 extending rearward from the block-shaped member main body 21, and by fixing the attachment piece 22 to an appropriate part of the top plate 12, the top plate 12 and the side plate 14 of the housing 1 z It is attached to the front near the corner. And the bulging part 23 is protruded integrally from this member main body 21 toward the front slightly. As shown in FIGS. 2 and 4, the bulging portion 23 is thinner than the thickness t <b> 1 of the member main body 21, and is formed with its upper surface matching the upper surface of the member main body 21. The lower part is a released space, and the shaft 4x projects from the lower surface of the bulging portion 23 toward the lower space.

  On the other hand, as shown in FIGS. 2, 3, 6, and the like, the movable member 3 has a member main body 31 that has substantially the same shape as the member main body 21 of the fixed member 2 in plan view, on the suspension base side of the door 15. It is attached to the missing part 15x provided in the corner part of the edge part 15a and the upper edge 15b, and the screw passage part for fixing to the attachment metal fitting 15y previously provided in the missing part 15x of the door 15 in the member main body 31. 32 is provided. And the bulging part 33 which has the axial hole 4y of an up-down direction is integrally protruded toward the front from the member main body 31. As shown in FIG. The bulging portion 33 is provided so as to overhang forward from the member main body 31 so as to ride on the upper surface of the member main body 31, and as shown in the hinge mechanism a1 of the left side storage furniture 1 in FIG. When the door 2 is closed, the bulging portion 33 of the movable member 3 is arranged in a space below the bulging portion 23 of the fixed member 21. The block shape formed by the member main body 31 of the movable member 3 complements the outline line of the door 15 when it is arranged in the missing portion 15x of the door 15 as shown in FIG. Like the hinge mechanism a1 of the storage furniture 1, when the door 2 is closed and overlapped with the member main body 21 of the fixing member 2, the missing portion 15x is almost completely complemented.

  Then, as shown in FIGS. 3 and 4, the shaft 4x hanging from the lower surface of the bulging portion 23 of the fixed member 2 is inserted into a shaft hole 4y provided on the upper surface of the corresponding bulging portion 33 of the movable member 3 to swell. As shown in FIG. 5, the doors 15 are rotatably supported via the movable member 3 by connecting the protruding portions 23 and 33. The outer peripheries of the bulging portions 23 and 33 are partially cylindrical, and as shown in FIG. 7, the protruding amount d1 of the bulging portions 23 and 33 from the front surface of the door 15 is made as small as possible so that the shaft 4x, the shaft hole 4y, etc. More specifically, a part of the shaft 4x and the shaft hole 4y located at the center of the bulging parts 23 and 33 are located on the front line of the door 15 so that the shaft part 4 is substantially in the same position as the front surface of the door 15. In addition, the shaft portion 4 composed of the shaft 4x, the shaft hole 4y, and the bulging portions 23 and 33 is brought close to the door 15 side to the extent that it is within the thickness. In other words, a part 4z of the shaft portion 4 is positioned within the wall thickness dimension D of the door 15. In this embodiment, the bulging portions 23 and 33 of the shaft portion 4 have a partial cylindrical shape, and the other part 4z of the shaft portion 4 has a partial cylindrical shape having a larger diameter than this. Even if a part of 4 is shaped to be continuous with the cylindrical surface of the bulging portions 23 and 33 as indicated by an imaginary line 4z 'in the same figure, this part 4z' is still located within the wall thickness dimension D of the door 15. Will be. Further, if the side plate 11 of the housing 1z is extended, the shaft portion 4 is positioned within the thickness t2. Further, in this embodiment, the shaft portion 4 is more than the thickness center m of the side plate 11. The side plate 11 is displaced to the outer surface side.

  In the state in which the door 15 is held at the closed position, the movable member 2 and the fixed member 3 are overlapped like the left hinge mechanism a1 in FIG. 2, and the front surfaces of the member main bodies 21 and 31 are substantially aligned. The bulging portions 23 and 33 projecting from the members 21 and 31 are also superposed vertically, and the outer periphery is aligned to form an apparently single cylindrical shaft portion 4. When the door 15 is rotated from this state toward FIG. 6 to FIG. 7 and the movable member 3 is pulled out from the fixed member 2, the bulging portion 33 of the movable member 3 bulges out of the fixed member 2 as shown in FIG. While rotating without changing the overlapping position with the portion 23, the portion of the movable member 3 where the fixed member 2 is superimposed, that is, the space s above the member main body 31 constituting the movable member 3 is opened. When the movable member 3 further rotates, as shown in FIG. 8, the upper surface 31a of the member main body 31 of the movable member 3 is the lower surface 33a of the bulging portion 33 of the movable member 3 constituting the shaft portion 4 of the adjacent hinge mechanism a1. Therefore, when rotated approximately 180 °, a part of the bulging portion 33 can ride on the open space s on the member main body 31, and the door 15 is adjacent to the adjacent door 15. You can face closely in parallel. That is, in the plan view shown in FIG. 9, the bulging portions 23 and 33 of the hinge mechanism a1 that supports the left door 15 seem to enter the wall thickness of the door 15 that has been rotated from the right side. Actually, as shown in FIG. 8, the shaft portion 4 composed of the bulging portions 23, 33 and the like is received in the open space s of the member main body 31 constituting the movable member 3, and the open space s is adjacent. It functions as an interference avoidance unit of the present invention that receives the shaft portion 4 and avoids interference.

  The above is mainly the description of the upper hinge mechanism a1, but the lower hinge mechanism a2 is basically the same as the upper hinge mechanism a1 except that it is vertically symmetrical. For this reason, the description about the concrete structure and effect including the following description is abbreviate | omitted.

As described above, the door opening / closing device A of this embodiment is configured such that the hinge mechanism a1 and the like are configured by slightly protruding the shaft portion 4 forward from the front surface of the door 15 between the housing 1z and the door 15. On the door 15 side, as shown in FIG. 8 and the like, there is an interference avoiding portion that avoids interference with the shaft portion 4 located slightly protruding forward from the front surface of the adjacent door 15 when rotated approximately 180 °. open space s is provided Rutotomoni, in which the shaft portion 4 is provided on the edge 15a of the substantially Tsumoto side along the width direction of the door 15.

If comprised in this way, when the door 15 is rotated about 180 degrees, interference with the axial part 4 of the door 15 which adjoins is avoided in the open space s, Therefore As shown in FIG. The protruding amount d1 from the door can be suppressed to a slight amount, and the inverted door 15 can be brought into close proximity to the front surface of the adjacent door 15 as shown in FIG. For this reason, without using a two-stage hinge or the like, the facing distance δ between the door 15 rotated 180 ° and the adjacent door 15 can be kept small, the appearance and the appearance are kept good, and the operating space in the front is not reduced as much as possible. It can be realized easily. Further, even when rotating 90 ° as shown in FIG. 7, since the shaft portion 4 is located at a position close to the housing 1z, the operation space is effective by suppressing the protrusion amount d2 of the door 15 forward from the housing 1z. Can be secured.
Further, as shown in FIG. 7, since the shaft portion 4 is substantially positioned on the edge 15a on the hanging side along the width direction of the door 15, when the door 15 rotates, the edge on the hanging side The radius of rotation of the portion 15a from the shaft portion 4 can be suppressed to be extremely small, and the edge 15a can be prevented from interfering with the housing 1z as much as possible. This is also effective for the purpose of suppressing the unnecessary protrusion of the door 15 when the shaft portion 4 is moved as close as possible to the housing 1z and rotated by 90 °.

  In particular, as shown in FIG. 7, the shaft portion 4 is provided close to the door 15 side so that at least a part 4z (or 4z ′) is located within the wall thickness D of the door 15. The structure of suppressing the protrusion amount d1 from the door front of 4 as small as possible can be effectively realized.

  Moreover, the interference avoidance part of this embodiment is the open space s formed in the thickness dimension of the door 15 with the opening operation | movement of the door 15, The door 15 reversed by rotation is in front of the door 15 which adjoins. Since the shaft part 4 of the hinge mechanism a adjacent to the open space s formed in the rotated door 15 is received when facing closely, without providing a special recess or the like only for that, The interference avoiding portion can be reasonably formed by utilizing the portion where the movable member 3 and the fixed member 2 are superbly superposed.

  Further, since the shaft portion 4 is located within the thickness t2 of the side plate 11 of the housing 1z, the inner surface 15b of the door 15 is prevented from protruding as much as possible inside the inner surface of the side plate 11 of the housing 1z when rotated 90 °. In other words, the protrusion amount t3 from the inner surface 11b of the side plate 11 to the inner surface 11 of the door 15 is suppressed as much as possible, and it is possible to effectively avoid the door 15 from being obstructed in the width direction when an article is taken in and out of the storage space. . In particular, in this embodiment, since the shaft portion 4 is displaced further to the outer surface side of the side plate 11 than the thickness center m of the side plate 11, the above effect is particularly effective.

  The hinge mechanism a1 includes the fixed member 2 fixed to the housing 1z and the movable member 3 fixed to the door 15. The fixed member 2 and the movable member 3 face the front from the front. The bulging portions 23 and 33 are provided, and the shaft portion 4 is simply connected between the respective bulging portions 23 and 33 by the shaft 4x, and is movable to the housing 1z and the door 15, respectively. Since the member 3 can be attached and the bulging portions 23 and 33 can be connected by the shaft 4x, the assembly can be simplified with a simple structure.

  At that time, the movable member 3 and the fixed member 2 are overlapped when closed, and the front surfaces are almost aligned. When the movable member 3 is pulled out, the bulging portion 33 of the movable member 3 changes the overlapping position with the bulging portion 23 of the fixed member 2. The portion of the movable member 3 where the fixed member 2 is superposed is released by moving away from the fixed member 2, and the open space s is adjacent to the shaft portion 4 constituting the adjacent hinge mechanism a1. The movable member 3 functions as an interference avoiding unit that avoids interference. When the movable member 3 and the fixed member 2 are in close contact with each other, the open space s is naturally formed when the movable member 3 is pulled out. Can be effectively used as the interference avoidance unit of the present invention.

  And the defect | deletion part 15x is provided in the suspending side of the door 15, and when the door 15 closes, the defect | deletion part 15x is filled and the fixed member 2 and the movable member 3 are arranged so that the external line of the door 15 may be supplemented. Therefore, the hinge mechanism a1 can be appropriately incorporated into the door 15.

  The storage furniture 1 of the present embodiment is configured by attaching the pair of doors 15 to the housing 1z in a double door state by the door opening and closing device A as described above. 90 ° opening and 180 ° opening can be appropriately performed, and the internal storage space can be effectively utilized while effectively ensuring the operation space on the front side.

  The specific configuration of each part is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, the hinge mechanism a1 of the present invention is not necessarily used only for supporting the door 15 on the housing 1z as in the above-described embodiment, and two support objects that are substantially flush with each other are rotated by 180 °. Various applications are possible for applications that require close polymerization. For this purpose, the hinge mechanism a1 may be configured as in the above embodiment. That is, the fixed member 2 having a part of the bulging part 23 and the movable member 3 having a part of the bulging part 33 are provided, and the bulging parts 23 and 33 are connected by the shaft 4x. As a result, the movable member 2 and the fixed member 3 are overlapped in a closed state, and when the movable member 2 is pulled out, the bulging portion 23 of the movable member 2 rotates without changing the overlapping position with the fixed member 3. In this case, when the portion of the movable member 2 that has overlapped with the fixed member 3 is opened, and the open space s is adjacent to another hinge mechanism a1, the shaft portion 4 constituting the hinge mechanism a1 By configuring so as to be an interference avoidance unit that avoids this interference, the same basic operational effects as in the above embodiment can be obtained. If each part is set according to the above, the specific effect can be made closer to that of the above embodiment.

  Further, as the interference avoiding portion, within the thickness of the door 15, there is of course an aspect in which a recess, a notch, a slit, or the like is provided on the inner surface side at a position for receiving the adjacent hinge mechanism when rotated 180 °. Is possible.
