Description

  The present invention relates to a storage, particularly to a storage installed in a narrow room or the like where a sufficient space for opening and closing a door cannot be secured. Alternatively, the present invention relates to a locker or other storage that can be used particularly preferably in a so-called “IT office” or “paperless office”, which is expected to appear in the near future.

In many cases, storage doors such as lockers are formed in a single plate shape, but in recent years, storage doors that have been configured in a so-called “folding type” have appeared.
Here, in the conventional folding door, there is only a connection part (hinge) located outside the storage when opened, and the connection part (hinge) is inside the storage when the storage door is opened. There was no one located in.
If the connection part (hinge) is configured to be located inside the storage when the door is opened, the connection part and the door itself are stored in the storage when the door is opened and closed. Alternatively, in order not to interfere with the storage shelves in the storage, the portion in the storage has to be a dead space, and the storage capacity is considered to be reduced accordingly.

However, for example, even if the installation space of the storage is so narrow that it is difficult to open the door in a normal storage, if the connection part (hinge) is located inside the storage when the door is opened, it will be opened. Since the dimensions of the door portion located outside the storage sometimes can be reduced, the storage door can be easily opened.
Therefore, there has been a demand for a storage of a type in which the connecting portion (hinge) is located inside the storage when the door is opened, and the storage capacity does not decrease.

  On the other hand, the applicant pays attention to the back side of the door, which is not utilized for storage, and is a type of storage that is of a folding type and in which the door connection part is located inside the storage when the door is opened. A storage has been proposed in which a storage shelf is provided on the back side of the door so that the above-described reduction in storage capacity due to dead space can be compensated (see, for example, Patent Document 1).

However, in such a conventional technique, since the storage part (storage shelf) is provided on the back side of the door, the storage case may fall down due to the weight of the storage part and the stored article when the door is opened.
JP 2004-84365 A

  The present invention has been proposed in view of the above-described problems of the prior art, and is a storage container of a type that is of a folding type and has a door connecting portion located inside the storage container when the door is opened. The purpose of the present invention is to provide a storage that can secure a sufficient storage capacity without causing the storage to fall down when opened.

  In the storage of the present invention, a first portion (11) having a small width dimension and a second portion (12) having a large width dimension are connected to each other via a hinge mechanism (13) so as to be relatively rotatable. In the storage provided with the door configured to be bendable, the first portion (11) has one end (11a) in the width direction at the end in the width direction of the opening (21) of the storage body (2). It is pivotally supported (11c), the hinge mechanism (13) is configured to be movable to the inner area of the storage, the second portion (12) is formed with a storage location (3) on the back side, and the door The center of gravity (12g) of the second part (12) is positioned in the inner region of the storage in the fully opened state of (1), and the opposite edge of the hinge mechanism (13) of the second part (12) A sleeve-like storage portion (111) is provided at each of the upper and lower ends of the door opening / closing handle (101) extending from the upper edge portion to the lower edge portion of the door. The lock pin accommodating member (102) is accommodated in the upper and lower sleeve-shaped accommodating portions (111) so as to be relatively rotatable, and a spiral groove (113) is formed. The lock pin accommodating member (102) is the second one. The lock pin accommodating member (102) is fixed to the upper and lower mounting margins (172) of the portion (12), and the upper end or the lower end of the lock pin accommodating member (102) is closed at the end face to form a lock pin storage chamber (121) having a circular cross section. The pin accommodating member (102) is formed with a long hole (125) in the longitudinal direction, and a slidable cylindrical portion (131) in the lock pin accommodating chamber (121) and a smaller diameter lock pin than the cylindrical portion (131). A lock pin (103) having a tip (132) penetrating the through hole (123) on the end surface of the housing member (102), and the lock pin (103) are energized to store the tip (132). Engagement hole The coil spring (105) to be engaged with (165) is housed, and the guide pin (104) is a long hole (125) of the lock pin housing member (102) and a spiral groove (113) of the sleeve-like housing portion (111). And is screwed into the cylindrical portion (131) of the lock pin (103).

According to the storage (A) of the present invention, the first part (11) and the second part (12) are connected to each other via a hinge mechanism (13) so as to be relatively rotatable, and can be bent. Since the hinge mechanism (13) is configured to move in the inner area of the storage when the door (1) is opened and closed, the space in front of the storage (traffic space when the door is opened) If the doors are the same, the size of the storage door in the direction of the door (thickness of the storage) should be increased with respect to a single door or an external folding door (method in which the hinge mechanism can move to the outside area of the storage). That is, the storage capacity can be increased. Alternatively, if the thickness of the storage is the same, the installation area including the passage space can be reduced from the back of the storage. As a result, it greatly contributes to the realization of space saving.
Further, since the hinge mechanism (13) is configured to move in the inner region of the storage (A) when the door (1) is opened and closed, the hinge mechanism (13) is located inside the storage (A). Compared with a storage type that does not move, the size of the portion of the door (1) that protrudes outside the storage (A) when the door (1) is opened is smaller. Therefore, when the door (1) is opened, the possibility that the door (1) interferes with a person passing in front of the storage (A) is reduced by that amount, and the necessary space in front of the storage (A) is reduced. Thus, it can contribute to space saving.

  Here, if the hinge mechanism (13) is configured to move in the inner region of the storage (A) when the door (1) is opened and closed, the hinge mechanism (13) can be moved within the storage (A) when the hinge mechanism (13) is moved. Although it is necessary to provide a dead space so as not to interfere with other members, in the present invention, since the second portion (12) has a storage location (storage shelf 3) formed on the back side, the hinge mechanism (13) It is possible to reliably prevent the storage capacity from deteriorating due to the movement trajectory in the storage (A).

  As a result of providing the storage location (3) on the back side of the second portion (12) of the door (1), when the door (1) is in a fully open state, the storage compartment (3) is stored by the weight of the article stored in the storage location (3). According to the present invention, the center of gravity (12g) of the second portion (12) is stored in the storage case (A) when the door (1) is fully opened. ), The center of gravity (12g) (of the second portion 12) of the door (1) remains in the storage (A) even when the door (1) is fully opened. Since it is on the inside, it is completely prevented that the storage (A) becomes unstable or falls due to the movement of the center of gravity (12g).

Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, a first embodiment of the present invention will be described with reference to FIGS.

Before describing the structure around the door, the configuration of the storage A will be described with reference to FIGS.
5 and 6, the storage A has a storage body 2 and a door 1. An opening 21 is provided in front of the storage body 2, and the opening 21 opens the door 1 when the door is closed. Accommodate. The storage A includes left and right side members 22, a rear member 23 (see FIG. 6), a floor plate 24, and a ceiling member 25 (see FIG. 5).

  As shown in FIG. 6, the interior of the storage A is partitioned into a dead space area A1 and a normal storage area A2. Here, the dead space area A1 is a space for avoiding interference with the door 1 when the door 1 is opened (see FIG. 2 or FIG. 3).

As shown in detail in FIGS. 4 and 5, in the normal storage area A <b> 2, in the illustrated example, three shelf boards 4 horizontally extend across the entire width in the left-right direction of the storage A from the substantially vertical center to the lower side. Is installed.
A first area A21 is defined by the ceiling plate 25 and the upper shelf board 4, and a second area A22 is defined by the upper and middle shelf boards 4 and 4, and the middle and lower shelf boards 4 and 4 are defined. The third area A23 is partitioned by the above, and the fourth area A24 is partitioned by the lower shelf board 4 and the floor board 24.

  In the first region A <b> 21, a hanger support member 6 for hanging the clothes hanger 5 is horizontally attached immediately below the ceiling member 25.

  In the illustrated example, the second area A22 is configured such that, for example, B5 size files and relatively small-sized books F1 can be stored vertically. The third area A23 is configured so that, for example, an A4 size file or a relatively large book F2 can be stored vertically. And the 4th field 24A is formed so that footwear can be stored.

As shown in FIGS. 1, 5, and 7, five storage shelves (storage locations) 3 are provided on the back surface of the second portion 12 of the door 1 in the illustrated example. Each storage shelf 3 stores, for example, a storage medium such as a CD, FD, MO, MD, and PM storage, documents, and the like, which are not explicitly shown in the figure.
Here, the width of the storage shelf 3 (the dimension in the direction of the arrow W in FIG. 1) is such that the storage shelf 3 is the shelf plate 4 in the middle of opening shown in FIG. 3 (the storage shelf 3 is not shown in FIG. 3). (See FIGS. 1 and 5).

Next, the configuration around the door 1 will be described in detail with reference to FIG.
In FIG. 1, a two-dot chain line indicates a state where the door 1 is fully opened.
Here, FIG. 2 shows a state in which the door 1 is fully opened, and FIG. 3 shows the opening / closing process by showing the three states of the door 1 in a closed state, a state in the middle of opening, and a fully opened state in the same figure. Show. In FIG. 3, the storage shelf 3 is not shown for the sake of simplicity.

In FIG. 1, a door 1 is connected to a first portion 11 having a relatively small width dimension and a second portion 12 having a relatively large width dimension via a hinge mechanism 13 so as to be relatively rotatable. And bendable.
The hinge mechanism 13 includes a first hinge pin 61 that engages with the first member 11, a second hinge pin 62 that engages with the second member 12, and a coupling portion 63.
The first portion 11 is pivotally supported at one end portion 11a in the width direction with respect to the end portion in the width direction of the opening portion 21 of the storage body 2 by a pivot point 11c. When the door 1 is opened, the hinge mechanism 13 is configured to move to an inner area (a dead space area for avoiding interference with the door when the door is opened) A1.

  In FIG. 1, the reference numerals with parentheses indicate the positions of the constituent elements when the door 1 is fully opened, and the numerals with parentheses and the numerals without parentheses are the same numbers. If so, the same components are shown.

  Here, the center of gravity 12g of the second portion 12 is located at the center of the second portion 12 in the same direction as the arrow indicating the dimension L1. And the width direction dimension L2 in the 2nd part 12 is formed below twice the length (L1) from the axial support part (axial support point) 11c of the 1st part 11 to the other end part.

  Since the dimension L1 is set to be not more than twice the dimension L2, the center of gravity 12g in the second portion 12 is stored in the storage shelf 3 when the door 1 is fully opened, particularly as shown by the two-dot chain line in FIG. If not, it is in the position shown in the figure. If it is stored in the storage shelf 3, it is positioned on a straight line indicated by an arrow g depending on its weight. Here, the position indicated by the reference numeral “12g” and any position on the arrow g are inside the storage A. Accordingly, in the previous state of the door 1, the center of gravity 12g in the second portion 12 is always located inside the storage A, and even if the storage shelf 3 is provided in the second portion 12 of the door 1, the illustrated implementation is performed. In the form, the storage A does not fall down.

In FIG. 3, when the storage shelf 3 (not shown) does not store, the center of gravity of the second portion 12 in the closed state of the door 1 is indicated by reference numeral 12g-1, and the second portion 12 in the middle of opening the door 1 is shown. The center of gravity is indicated by reference numeral 12g-2.
Then, if the FD or the like is stored in the storage shelf 3 not shown in FIG. 3, the center of gravity of the second portion 12 in the closed state of the door 1 is located anywhere on the arrow g1, and the door 1 is opened. The center of gravity of the second portion 12 in the middle is located anywhere on the arrow g2.
That is, the center of gravity 12g in the second portion 12 is always located inside the storage A regardless of whether or not it is stored in the storage shelf 3 (not shown). Even if the storage shelf 3 is provided, the storage A does not fall down.

  Referring again to FIG. 1, a guide pin 12 </ b> P projects from the approximate center of the second member 12. Here, a horizontal direction (direction orthogonal to the arrow W) distance L12 between the guide pin 12P and the second hinge pin 62 is a horizontal distance L11 from the shaft fulcrum 11c of the first member 11 to the first hinge pin 61. Are set to be equal.

  In FIG. 2, guide grooves 21 t are formed on the upper and lower edges of the opening portion 21 of the storage A to guide the guide pins 12 </ b> P. Here, the guide groove 21t is formed at a position corresponding to the center in the thickness direction (the direction of the arrow t in FIG. 2) in the first portion 11 and the second portion 12, and the door 1 is closed when the door 1 is closed. The position of the guide pin 12P (the position of the reference numeral 12P without parentheses in FIG. 1; not shown in FIG. 2) and the position of the guide pin 12P when fully opened (the position of the reference numerals 12P with parentheses in FIG. 1: FIG. 2 is formed as a straight line connecting the position of the reference numeral 12P in FIG.

  When the door 1 is opened and closed, the guide pin 12P projecting from the second portion 12 slides in the guide groove 21t, thereby guiding the movement locus of the second portion 12 to be constant. ing. As a result, even if the gap between the storage shelf 3 and the shelf plate 4 is made as small as possible, if the movement locus of the second portion 12 is constant, interference between the two is prevented.

  According to the storage of the first embodiment having the above-described configuration, the door 1 of the storage A is connected so that the first portion 11 and the second portion 12 are relatively rotatable via the hinge mechanism 13. It is configured to be bendable. When the door 1 is opened, the hinge mechanism 13 that connects the first part 11 and the second part 12 moves to the inner area of the storage A, so that the door 1 is a part of the door 1 and the door 1 is opened. Sometimes, the portion that is not stored in the inner area of the storage A can be made extremely small.

And since the part which is not accommodated in the inner side area of the storage A when the door 1 is opened can be made extremely small, if the space in front of the storage (the passage space when the door is opened) is the same, a single door or an external folding door The dimension (thickness of the storage) in the door side direction of the storage can be increased (the storage capacity can be increased) with respect to (the method in which the hinge mechanism can move to the outside region of the storage).
Alternatively, if the thickness of the storage is the same, the installation area including the passage space from the back of the storage to the front of the storage can be reduced (realization of space saving).

Here, since the hinge mechanism 13 moves to the inner region of the storage A, a dead space must be provided inside the storage A in order to prevent interference with the moving hinge mechanism 13, but in the first embodiment, Since the storage shelf 3 is provided on the back side (the dead space side) of the second portion 12, even if the hinge mechanism 13 moves to the inner area of the storage A, the storage capacity of the storage A does not decrease.
In other words, the reduction in the storage capacity due to the dead space (A1 area) when the door is opened is the five-stage storage in the illustrated example formed on the back side of the second portion 12 in a plurality of vertical directions. The shelf 3 can make enough recovery.

  Furthermore, since the center of gravity 12g of the second portion 12 is positioned in the inner area of the storage A in any of the closed state, the middle of opening, and the fully opened state, the door 1 is opened and closed. Even if the center of gravity 12g of the second portion 12 moves, the storage A is prevented from falling.

The storage A of the first embodiment described above is suitable for use as a locker for a so-called “IT office” or “paperless office” that is expected to appear in the near future.
That is, in such an IT office, paper (files, books, etc.) is almost disappeared, and a little remaining paper (materials) is expected to be stored in individual lockers, and also stored in a disk or other memory. The demand for media storage is expected to increase.

Therefore, in the IT office locker, the space A21 for clothes is sufficient if it can store the outerwear. In addition, the shelf board 4 partitions the height direction so that books and footwear can be stored. It is expected that a use mode in which the storage medium (storage for CD, FD, MO, MD, PM, etc.) is stored in the storage portion (storage shelf) 3 will be generalized.
In the first embodiment shown in FIGS. 1 to 7, the fitness is extremely high for such prediction.

Next, a second embodiment of the present invention will be described with reference to FIGS.
The storage according to the second embodiment of FIGS. 8 to 19 is substantially the same as the first embodiment described above, but is provided with a handle extending from the upper edge portion to the lower edge portion of the door. The structure regarding the point and the locking mechanism for opening and closing the door is different from the first embodiment.
In the first embodiment shown in FIGS. 1 to 7, the form of the handle is not particularly limited.

  In FIG. 8, the rocker generally indicated by reference numeral 160 has a door 150 that is pivotally attached by a hinge H.

A handle 1 extending from the upper edge portion to the lower edge portion of the door 150 is provided at the edge of the door 150 opposite to the hinge H, in FIG. Then, as will be described in detail later, the door 150 is configured to be opened and closed by any portion of the handle 101 extending from the upper edge portion to the lower edge portion of the door 150.
More specifically, the boundary between the handle 101 and the top plate 162 of the locker 160 and the boundary between the handle 101 and the bottom plate 162 of the rocker 160 are provided with a lock mechanism described in detail with reference to FIGS. Is provided.

With reference to FIGS. 9-20, opening and closing of a door is demonstrated.
Here, FIG. 9 shows a longitudinal sectional view (see also FIG. 16) of the upper corner portion of the door 150 on the side where the handle 101 is located, FIG. 10 is an XX step view of FIG. 9, and FIG. The YY step surface drawing is shown.
In the illustrated embodiment, the door 150 is configured vertically symmetrically, and has similar locking mechanisms at two locations above and below the door 150.

  9 to 11, a sleeve-like accommodation portion 111 that accommodates the lock pin accommodation member 102 is provided at the upper and lower ends of the handle 101. Here, in the illustrated embodiment, a lock mechanism at the upper end of the handle 101 will be described. That is, in FIGS. 9-20, only the upper end part side of the handle 101 is shown.

In FIG. 10, the handle 101 (upper end) is shown in a state in which the sleeve-like storage portion 111 is fitted to the handle 101. For example, the handle 101 has a square cross-sectional shape and has an annular sleeve-like shape. The portion 111 may be inscribed in the handle 101 having a square cross section.
In the case shown in FIG. 10 as well, in the case described above (when the annular sleeve-shaped accommodating portion 111 is configured to be inscribed in the handle 101 having a square cross section), the handle 101 and the sleeve-shaped accommodating portion 111 (for example, made of aluminum) are used. Can be manufactured by extrusion molding (aluminum extrusion molding).

A cylindrical lock pin storage member 102 is stored in the sleeve-shaped storage portion 111. The sleeve-like accommodation portion 111 is rotatable relative to the lock pin accommodation member 102 (fixed to the door 150 main body as will be described later).
Further, as shown in FIG. 12 (viewed in the direction of arrow A in FIG. 10), the sleeve-shaped housing portion 111 has a spiral first groove portion (hereinafter, the spiral first groove portion is referred to as a first guide groove). ) 113 is formed, and the first guide groove 113 passes through the inside and the outside of the sleeve-shaped housing portion 111.

As shown in detail in FIG. 13, the lock pin storage member 102 is formed with a lock pin storage chamber 121 that is a space section having a circular cross section with an open lower end, and an inner diameter portion of the open lower end of the storage chamber. Is formed with a female screw 122.
A pin through-hole 123 through which a tip 132 (lock member) of a lock pin 103 (see FIG. 14) to be described later passes is formed at the center of the upper end surface of the lock pin storage member 102, and is near the upper end of the lock pin storage member 102. A male screw 124 is formed on the outer periphery of the.

As shown in FIG. 9, the male screw 124 formed on the outer periphery of the upper end portion of the lock pin housing member 102 is screwed with the female screw 125 formed on the mounting margin 172 of the ceiling plate 170. The outer diameter of the portion where the male screw 124 is formed on the outer periphery of the upper end of the lock pin housing member 102 is smaller than the portion below that (the portion where the male screw 124 of the lock pin housing member 102 is not formed). Therefore, the boundary between the upper end portion of the lock pin housing member 102 where the male screw 124 is not formed and the portion where the male screw 124 is formed is a step, and the step is It abuts against the mounting margin 172 and acts as a stopper.
The lock pin storage member 102 is attached to the ceiling plate 170 at the upper end of the door main body 150 with a screw 174, and the lock pin storage member 102 is locked and fixed by the screw 174.
In addition, a thrust washer 107 is interposed between the lower surface of the mounting margin 172 of the ceiling plate 170 and the upper end of the sleeve-like housing part 111 at the upper end of the handle 101 in order to facilitate the rotational movement of the sleeve-like housing part 111. It is disguised.

  In FIG. 13, a second guide groove 125 having a long hole shape is formed in the lock pin storage chamber 121, and the second guide groove 125 extends in the longitudinal direction of the lock pin storage member 102 (vertical direction in FIG. 5). The lock pin storage chamber 121 and the outside are penetrated.

  As shown in FIGS. 9 and 11, the lock pin housing member 102 is fixed to the ceiling plate 170 by screws 174, and the male screw 124 formed on the outer periphery of the upper end portion of the lock pin housing member 102 is a ceiling plate. The lock pin storage member fixed to the ceiling plate 170 (of the door main body 150) even if the sleeve-shaped storage portion 111 is rotated because the internal thread 125 formed in the mounting allowance portion 172 of the 170 is screwed. 102 does not rotate. In other words, when the handle 101 is rotated, a relative rotational motion (between the sleeve-shaped storage portion 111 that rotates simultaneously with the handle 101 and the lock pin storage member 102 (fixed to the door body 150)). Rotation).

  As shown in FIG. 14, the lock pin 103 has a cylindrical portion 131 that slides smoothly without looseness in the lock pin storage chamber 121 of the lock pin storage member 102, and has a hemispherical tip that is narrower in diameter than the cylindrical portion 131. And a circular protruding portion 133 located on the opposite side of the tip portion 132 with respect to the cylindrical portion 131.

  A guide pin 104 protrudes from the outer periphery of the cylindrical portion 131 in a direction orthogonal to the central axis direction of the lock pin 102 (vertical direction in FIG. 14). And the guide pin 104 is implanted in the cylindrical part 131 with the screw which is not shown in figure.

  9 and 11, a biasing coil spring 105 is accommodated in the lock pin accommodating member 102, and a plug 106 (see FIG. 15) is provided at the lower end of the lock pin accommodating member 102. It is screwed.

Next, a mode in which the lock pin 103 is assembled to the lock pin housing member 102 will be described mainly with reference to FIG.
First, the lock pin 103 (not shown) in a state before the guide pin 104 is screwed is inserted into the lock pin storage chamber 121 of the lock pin storage member 102 as a single unit.
Then, the biasing coil spring 5 is inserted into the lock pin storage chamber 121 and the plug 106 is attached to the lower end of the lock pin storage member 102.

  Here, as shown in FIG. 15, the plug 106 has a male screw 161 on the outer periphery, and when the plug 106 is attached to the lower end of the lock pin storage member 102, the male screw 161 of the plug 106 is connected to the lock pin storage member. What is necessary is just to make it screw in the internal thread 122 formed in the internal diameter part of 102 lower end.

  In the state shown in FIG. 12, that is, in the state where the lock pin 103 and the biasing coil spring 105 are assembled in the lock pin storage member 102 (in the lock pin storage chamber 121), the sleeve 101 is formed at the upper end of the handle 101. The upper end portion 113 a of the spiral first guide groove 113 and the upper end 125 a of the second guide groove 125 formed in the vertical direction of the lock pin housing member 102 have substantially the same height. In other words, the vertical position in FIG. 12 is substantially the same. And the lower end part 113b of the 1st guide groove 113 and the lower end 125b of the 2nd guide groove 125 formed in the lock pin accommodating member 102 are substantially the same height (In FIG. It will be roughly the same).

As shown in FIG. 12, in the state where the upper and lower end portions 113a and 113b of the first guide groove 113 and the upper and lower end portions 125a and 125b of the second guide groove 125 are substantially the same height, The guide pin 104 is screwed into the cylindrical portion 131 of the lock pin 103 so as to penetrate both the groove 113 and the second guide groove 125, and the guide pin 104 is inserted into the lock pin 103 (the cylindrical portion 131). Make it project.
Thereby, the assembly of the lock pin housing member 102 and the lock pin 103 is completed.

  9 to 12 and 16 show a locked state, that is, a state where the handle 101 is not pulled (the handle is not operated). At this time, the relative positional relationship between the first guide groove 113 and the second guide groove 125 is indicated by a solid line in FIG.

In the locked state (FIGS. 9 to 12 and 16), the lock pin 103 is pushed upward by the repulsive force of the coil spring 105 (see FIGS. 9 and 11: not shown in FIG. 12) (FIGS. 9 and 12). 11), the tip 132 of the lock pin 103 protrudes above the lock pin storage member 102, and is inserted into an engagement hole (receiving portion) 165 formed in the bottom plate 163 of the top plate 162 of the locker (storage) 160. Engage.
When the distal end portion 132 of the lock pin 103 is inserted into and engaged with the engagement hole (receiving portion) 165 of the bottom plate 163 in the top plate 162, the door 150 maintains the locked state.
In FIGS. 9 and 11, the bottom plate 163 and the engagement hole 165 (in the top cover 162) are indicated by a two-dot chain line.

Here, the repulsive force of the coil spring 105 is transmitted to the spiral first guide groove 113 via the lock pin 103 and the guide pin 104, and is converted into a rotational force by the spiral guide groove 113. The rotational force is transmitted to the handle 101 via the sleeve-shaped housing portion 111. That is, the handle 101 also receives the reaction force of the coil spring 105.
When the door 150 is kept locked, the repulsive force of the coil spring 105 (the converted rotational force) is transmitted to the handle 101. Therefore, as shown in FIG. The grip portion 112 is always urged to a position that is flush with the front surface 150t of the door 150 (in a direction opposite to the arrow B in FIG. 18).

Next, with reference to FIGS. 17-20, the case where the handle 101 is pulled and the door 150 is opened is described.
