  A first embodiment of the present invention will be described with reference to FIGS.

  1 and 2, reference numeral 1 denotes a storage shelf which is a storage device. The storage shelf 1 is a fixed storage in which an object to be stored (not shown) such as tableware is detachable through an opening 2 on the front surface. A shelf body 3 as a member is provided.

  The shelf body 3 is rotatably provided with an opening / closing door 4 that is a movable member that rotates in the opening direction to close the opening 2 and rotates in the closing direction to open the opening 2. The open / close door 4 has a plate-like engaging portion 6 protruding from the door main body plate portion 5 toward the shelf main body 3 side at the upper end portion at the end opposite to the rotation fulcrum side. On the upper surface side of the distal end portion of the engaging portion 6, an engaging convex portion 7 that is convex upward is formed.

  In addition, the storage shelf 1 normally allows the opening / closing door 4 to rotate with respect to the shelf body 3, but in the event of a vibration such as an earthquake, the stored items to be stored do not jump out of the shelf body 3. A restriction device (locking device) 10 that restricts the rotation (movement) of the opening / closing door 4 in the opening direction with respect to the shelf body 3 is provided. The restriction device 10 is provided on the lower surface of the upper plate portion 9 of the shelf body 3, for example. Is provided.

  As shown in FIGS. 3 to 7, the regulating device 10 is made of a box-shaped resin fixedly attached to the lower surface of the upper plate portion 9 of the shelf body 3 by means of a fixture (not shown) such as a bolt. A body 11, an elastically deformable resin-made restricting body 12 provided in the body 11, and a plurality of (for example, 4) which are provided on the restricting body 12 so as to be movable in the front-rear direction and aligned in the left-right direction. And a metal sphere 13 which is a seismic body.

  In a normal state, the spherical body 13 is positioned at the deformation-permitted position on the restricting body 12, so that the restricting body 12 is elastically deformed upward by the engagement with the engaging portion 6 of the opening / closing door 4 and the opening / closing of the opening / closing door 4. Allow movement.

  On the other hand, at the time of vibration, the sphere 13 moves on the restricting body 12 from the deformation permissible position (standby position) to the deformation restricting position (moving position) and is positioned at the deformation restricting position on the restricting body 12. 12 does not elastically deform to the position where the engaging portion 6 comes out, engages with the engaging portion 6 of the opening / closing door 4 and restricts the rotation of the opening / closing door 4 in the opening direction.

  That is, when at least one sphere 13 among the plurality of spheres 13 is positioned at the deformation regulation position on the regulation body 12 due to vibration, the sphere 13 regulates the elastic deformation upward of the regulation body 12, and thus the regulation body 12 is The elastic deformation is prevented by the sphere 13 and the rotation of the opening / closing door 4 in the opening direction is restricted by the engagement with the engaging portion 6 of the opening / closing door 4.

  Here, the main body 11 includes a case member 23 in which an upper surface opening 21 and a front surface opening 22 are formed, and a lid member 24 attached to the upper portion of the case member 23 so as to close the upper surface opening 21. It is configured.

  In the main body 11, in addition to the regulating body 12 and the sphere 13, a movable body (push latch) 16 that can move in the front-rear direction, and a coil spring 17 that is a plurality of urging bodies that urge the movable body 16 forward. In addition, a substantially Z-shaped pin 18 attached to the hole 19 of the moving body 16 is accommodated.

  Further, a pin passage 27 to which the pin 18 can move is recessed in the bottom plate portion 25 of the case member 23 of the main body 11 so as to be positioned around the substantially heart-shaped convex portion 26. For this reason, when the user rotates the opening / closing door 4 in the opening direction, when the user pushes the opening / closing door 4 in the closing direction, the movable body 16 is released from the coil spring 17 by the disengagement of the pin 18 and the convex portion 26. It moves forward by the urging force and pushes the engaging portion 6 to rotate the door 4 in the opening direction. That is, the regulating device 10 has such a known push latch function.

  The restricting body 12 is provided integrally with the holding portion 31 held by the main body 11 so as to be sandwiched between the bottom plate portion 25 of the case member 23 and the lid member 24, and the front end portion (front end face) of the holding portion 31. And a plurality of, for example, two left and right plate-like elastic deformation portions 32 formed with engagement convex portions 33 that can be engaged with the engagement portions 6 of the door 4 on the lower surface side. Each elastic deformation part 32 can be individually bent and elastically deformed with the base end side, which is a connection part with the holding part 31, as a fulcrum (see FIG. 5B).

  A plurality of longitudinally extending guide grooves (guide grooves) 35 that are parallel to each other are formed on the upper surface side of each elastic deformation portion 32. In other words, the restricting body 12 has a plurality of, for example, four guide grooves 35 that extend in the front-rear direction and have a front, rear, and lower inclination, and the guide grooves 35 are inclined on the guide grooves 35 (inclined grooves that are gradually raised and inclined forward. On the bottom surface), the spheres 13 are placed one by one so as to be movable in the front-rear direction along the guide groove 35.

  The sphere 13 is normally located on the guide groove 35 at the deformation-permitted position in contact with the deformation-permitted position stopper portion (first stopper portion) 36 due to its own weight. While moving along 35, it moves forward and comes into contact with the deformation restricting position stopper portion (second stopper portion) 37 and is positioned at the deformation restricting position.

  The stopper portion 36 for the deformation allowing position is formed on the upper surface side of the restricting body 12, and the stopper portion 37 for the deformation restricting position is formed on the lower surface side of the lid member 24 of the main body 11. The spherical body 13 placed directly on the bottom surface of the inclined groove of the guide groove 35 is movable between the stopper portions 36 and 37 on the bottom surface of the inclined groove of the guide groove 35.

  In this example, the four guide grooves 35 do not have the same length dimension (vibration auxiliary stroke) in the front-rear direction, for example, and the inner two guide grooves 35 are the outer two guide grooves 35. Longer than. Further, the inclination angle (inclination angle of the bottom surface of the guide groove) α of the guide groove 35 with respect to the horizontal direction before the elastic deformation portion 32 is elastically deformed is the same in the four guide grooves 35. The diameters (sizes) of the four spheres 13 are all the same.

  Next, the operation and the like of the restriction device 10 will be described.

  First, the normal operation will be described with reference to FIGS.

  FIG. 6A shows a state in which the opening / closing door 4 is located at a predetermined closed position and the opening 2 is closed (door closed state). At this time, the pin 18 and the convex portion 26 are engaged with each other. Yes.

  Then, when the user pushes the opening / closing door 4 in the closing direction to open the opening / closing door 4, the engagement between the pin 18 and the convex portion 26 is released as shown in FIGS. 6 (b) to 6 (d). As a result, the moving body 16 moves forward by the urging force of the coil spring 17 and pushes the engaging portion 6 to rotate the open / close door 4 in the opening direction.

  At this time, since the spherical body 13 is positioned at a deformation allowable position on the guide groove 35 of the elastic deformation portion 32 of the restriction body 12, the elastic deformation portion 32 of the restriction body 12 is engaged with the engagement portion 6 of the opening / closing door 4. The opening / closing door 4 is allowed to rotate by elastically deforming upward. The elastic deformation portion 32 returns to its original shape by the elastic restoring force after passing through the engaging portion 6.

  Further, when the user pushes the opening / closing door 4 in the closing direction in order to close the opening / closing door 4, the moving body 16 is pressed by the engaging portion 6 as shown in FIGS. As a result, the pin 18 and the convex portion 26 are engaged with each other and the original door is closed.

  Also in this case, since the spherical body 13 is located at a deformation allowable position on the guide groove 35 of the elastic deformation portion 32 of the restriction body 12, the elastic deformation portion 32 of the restriction body 12 is in contact with the engaging portion 6 of the opening / closing door 4. The opening / closing door 4 is allowed to rotate by elastically deforming upward by the engagement. The elastic deformation portion 32 returns to its original shape by the elastic restoring force after passing through the engaging portion 6.

  Thus, at normal times, the user can freely rotate the door 4 in the opening direction and the closing direction.

  Next, the operation during vibration will be described with reference to FIGS.

  FIG. 7A shows a state where the opening / closing door 4 is located at a predetermined closed position and the opening 2 is closed (door closed state). At this time, the pin 18 and the convex portion 26 are engaged with each other. Yes.

  Then, when the open / close door 4 is pushed in the closing direction by a vibration during an earthquake, etc., as shown in FIGS. 7B to 7D, the engagement between the pin 18 and the convex portion 26 is released. As a result, the moving body 16 moves forward by the urging force of the coil spring 17 and pushes the engaging portion 6 to rotate the open / close door 4 in the opening direction.

  However, at this time, since the sphere 13 moves while rolling from the deformation permission position to the deformation restriction position on the guide groove 35 due to the vibration and is located at the deformation restriction position, the elastic deformation portion 32 of the restriction body 12 is Therefore, the elastic deformation of the opening / closing door 4 by the engagement with the engaging portion 6 is restricted.

  Therefore, the elastic deformation portion 32 of the regulating body 12 is prevented from bending elastic deformation upward by the spherical body 13, and the engagement convex portion 33 of the elastic deformation portion 32 and the engagement convex portion 7 of the engagement portion 6 are engaged. Accordingly, the opening / closing of the opening / closing door 4 is restricted.

  As a result, the door closed state of the open / close door 4 is maintained, and the opening 2 of the shelf body 3 remains closed by the open / close door 4.

  Thus, the closed state of the opening part 2 of the shelf main body 3 is maintained at the time of a vibration, and the to-be-stored object in the shelf main body 3 does not jump out.

  According to the restricting device 10, the sphere 13 is normally positioned at the one end side deformation allowable position (free position) on the guide groove 35 of the restricting body 12, so that the restricting body 12 is engaged with the engaging portion 6. Accordingly, the opening / closing door 4 is allowed to rotate, and the spherical body 13 is positioned at the deformation regulating position (lock position) on the other end side of the guiding groove 35 of the regulating body 12 at the time of vibration. Since it is the structure which engages with the engaging part 6 and controls the rotation of the door 4, the number of parts is smaller than that of the conventional device, and the structure can be simplified.

  Further, the restricting body 12 has a plurality of guide grooves 35 parallel to each other, and the spherical body 13 is provided on each guide groove 35 so as to be movable (rollable) along the guide grooves 35. The seismic performance with respect to an earthquake can be improved, and accordingly, the rotation of the door 4 with respect to the shelf body 3 can be appropriately restricted during a vibration such as an earthquake.

  In the above embodiment, the configuration in which the lengths of the plurality of guide grooves 35 are different from each other has been described. However, as in the second embodiment shown in FIG. The strokes may all be the same.

  Further, the inclination angles α of the plurality of guide grooves 35 are not limited to the same configuration. For example, as in the second embodiment shown in FIG. 8, the inclination angles α1 of the two inner guide grooves 35 and the outer side The two guide grooves 35 may have different inclination angles α2. For example, a configuration in which the lengths of the four guide grooves 35 are different from each other, a configuration in which the inclination angles of the four guide grooves 35 are different, or the like may be employed.

  Furthermore, the diameters of the plurality of spheres (seismic bodies) 13 are not limited to the same configuration. For example, as in the third embodiment shown in FIG. The diameter of the two spheres 13 may be different. For example, a configuration in which the diameters of the four spheres 13 are different from each other, or a configuration in which the masses of the spheres 13 are different depending on the material or the like although the diameters are the same may be used.

  Further, the regulating device 10 is not limited to the one having a push latch function, and includes a moving body 16, a coil spring 17, a pin 18, and the like as in the fourth embodiment shown in FIGS. 10 and 11, for example. Alternatively, a configuration without a push latch function may be used.

  Also in the fourth embodiment, the restricting body 12 opens and closes when the sphere 13 is positioned at the deformation allowable position on the restricting body 12, as shown in FIGS. 10 (a) to 10 (f). The door 4 is elastically deformed by the engagement with the engaging portion 6 to allow the opening / closing door 4 to rotate, and during the vibration, the sphere 13 is placed on the regulating body 12 as shown in FIGS. 11 (a) and 11 (b). The restricting body 12 engages with the engaging portion 6 of the open / close door 4 to restrict the rotation of the open / close door 4.

  In any of the embodiments, the case where the seismic body is the sphere 13 has been described. However, the seismic body may be a shape other than the sphere, for example, that slides along the guide groove.

  Furthermore, the seismic body such as the sphere 13 is not limited to a configuration in which the seismic body such as the sphere 13 can move only in the front-rear direction on the regulating body 12. It may be configured to be movable in the horizontal direction.

  Although several embodiments of the present invention and modifications thereof have been described, the above-described embodiments and modifications can be appropriately combined without departing from the gist of the present invention.
