It is possible to prevent the shutter 10 from becoming immovable.

  Further, as shown in FIGS. 5A and 5B, on the front side of the coil spring 61, a cylindrical coil spring guide frame 64 as an elastic member guide member extending in the vertical direction stands upward from the lower connection frame 44. It is set up. The upper end portion of the coil spring guide frame 64 is supported by, for example, a cylindrical auxiliary frame 65 extending in the left-right direction between the upper frames 41 d and 42 d. The coil spring guide frame 64 is in close proximity to the coil spring 61, and as described later, the coil spring 61 and the shutter 10 do not run wild in the front-rear direction when the coil spring 61 bends upward or downward. , And functions as a guide for the coil spring 61. The coil spring guide frame 64 may be in contact with or separated from the coil spring 61. Further, the coil spring guide frame 64 is provided with a vertically extending relief groove 64 a that accommodates the release engagement claw 62 and the close engagement claw 63. The relief groove 64 a allows the open engagement claw 62 and the close engagement claw 63 to move without interfering with the coil spring guide frame 64.

  In the storage device with shutter 1, when the shutter 10 moves, the shutter 10, the release engagement claw 62, and the close engagement claw 63 are the frame body 40, the lower connection frame 44, the upper connection frame 45, the auxiliary frame The shape, size, and arrangement position are set so as not to interfere with 65 and the like.

  Next, the operation of the shutter-equipped device 1 having the above-described configuration will be described.

  When the shutter 10 is moved in the opening direction (downward) from the shutter intermediate position (see FIGS. 5A and 5B), the opening engagement claw 62 and the closing engagement claw 63 also move in the opening direction and are opened. The engagement claws 62 approach the coil spring 61, and the closing engagement claws 63 move away from the coil spring 61. Then, the shutter 10 is moved from the shutter middle position by a half distance (d / 2) of the distance d between the open engagement claw 62 and the close engagement claw 63 (hereinafter referred to as the open contact position) ), The coil spring 61 is accommodated in the recess 62a of the release engagement claw 62, and the release engagement claw 62 engages with the coil spring 61 (see FIGS. 6A and 6B). ).

  From this state, when the shutter 10 is further moved in the opening direction, the release engagement claw 62 moves downward while maintaining the engagement with the coil spring 61, pulls the coil spring 61, and moves the coil spring 61 downward. I can feel it. The coil spring 61 is stretched by the release engagement claw 62, and generates an upward elastic force on the shutter 10 through the release engagement claw 62 (see FIG. 7). The elastic force biases the shutter 10 in the closing direction. An upward elastic force from the coil spring 61 acts on the shutter 10 against its own weight at the rear face portion 3 so that a part or a front portion of the force urging the shutter 10 in the opening direction by the own weight of the shutter 10 is offset Thus, the operability of the shutter 10 is improved.

  By further moving the shutter 10 in the opening direction, the force of the shutter 10 by its own weight to bias the shutter 10 in the opening direction increases, but the coil spring 61 is further stretched to close the shutter 10 of the coil spring 61 The power to bias is also increasing. For this reason, in a state where the shutter 10 is moved in the opening direction from the open contact position (see FIGS. 6A and 6B), the good operability of the shutter 10 is maintained by the elastic force of the coil spring 61. Be done.

  When the shutter 10 is further moved in the opening direction and the shutter 10 reaches the opening position (see FIG. 7), the shutter 10 is provided on, for example, the guide rails 20 and 30 or the right side frame 41 and the left side frame 42 The shutter 10 abuts against the stopper. As shown in FIG. 7, in the state where the shutter 10 is in the open position, the release engagement claw 62 is located on the rear surface portion 3. On the other hand, the closing engagement claw 63 is located on the lower surface 5 together with a part near the rear end 14 of the shutter 10. Also, the opening 8 is opened.

  As described above, the shutter 10 moves in the opening direction in the region from the release contact position where the release engagement claw 62 starts to engage with the coil spring 61 to the release position (hereinafter also referred to as the release engagement region). During the operation, the release engagement claw 62 and the coil spring 61 are engaged, and the coil spring 61 biases the shutter 10 in the closing direction via the release engagement claw 62 to improve the operability of the shutter 10. ing.

  Further, even when the coil spring 61 is pulled by the release engagement claw 62, the coil spring 61 is sandwiched between the shutter 10 and the coil spring guide frame 64, so that the runaway of the coil spring 61 is suppressed. Disengagement of the engagement with the release engagement claw 62 is prevented.

  In the open engagement region, the force urging the shutter 10 by its own weight in the opening direction balances the force urging the shutter 10 in the coil spring 61 in the closing direction, or the shutter 10 of the coil spring 61 For example, the arrangement position of the release engagement claw 62, the spring constant of the coil spring 61, the weight of the shutter 10, and the like are set so as to be larger than the force for biasing in the closing direction.

  When moving the shutter 10 in the closing direction from the open position in which the opening 8 is opened, the coil spring 61 biases the shutter 10 in the closing direction against the force in the opening direction by the weight of the shutter 10. Therefore, the operation of moving the shutter 10 in the closing direction is easy. While the shutter 10 is moving in the closing direction in the opening engagement area, the operation of the shutter 10 is facilitated by the engagement between the opening engagement claw 62 and the coil spring 61. Contrary to the movement of the shutter 10 in the opening direction, as the shutter 10 moves the opening engagement area in the closing direction, the force in the opening direction by the weight of the shutter 10 decreases, and a coil spring The force for biasing the shutter 10 in the closing direction 61 also becomes smaller.

  When the shutter 10 is further moved in the closing direction and the shutter 10 exceeds the release engagement area (see FIGS. 6A and 6B), the release engagement claw 62 and the coil spring 61 are separated and engagement therebetween As a result, the coil spring 61 does not bias the shutter 10.

  From this state, until the shutter 10 is moved further in the closing direction by the distance d between the open engagement claw 62 and the close engagement claw 63, the coil spring 61 is not pulled (unloaded state) (initial state) , And extends into the space between the release engagement pawl 62 and the closure engagement pawl 63.

  The shutter 10 is further moved in the closing direction, and the shutter 10 is moved in the closing direction by a half distance (d / 2) of the distance d between the release engagement claw 62 and the closure engagement claw 63 from the shutter intermediate position When the shutter 10 reaches a position (hereinafter, also referred to as a closing contact position), the coil spring 61 is accommodated in the recess 63a of the closing engagement claw 63, and the closing engagement claw 63 engages with the coil spring 61 from the opening direction side. (See FIGS. 8A and 8B).

  When the shutter 10 is further moved in the closing direction from the closing contact position, the closing engagement claw 63 moves upward while maintaining the engagement with the coil spring 61, pulls the coil spring 61, and moves the coil spring 61 upward. (See Figure 9). The coil spring 61 is stretched by the closing engagement claw 63 and generates a downward elastic force on the shutter 10 via the closing engagement claw 63. The shutter 10 is urged in the opening direction by this elastic force. Since a downward (opening direction) elastic force from the coil spring 61 acts on the shutter 10 against the force in the closing direction of its front face 2 due to its own weight, the shutter 10 with its own weight is attached in the closing direction. Part or all of the force is offset, and the operability of the shutter 10 is improved.

  By further moving the shutter 10 in the closing direction, the force of the shutter 10 by its own weight urging the shutter 10 in the closing direction is increased, but the coil spring 61 is further stretched to open the shutter 10 of the coil spring 61 The power to bias is also increasing. For this reason, in a state where the shutter 10 is moved in the closing direction from the closed contact position (see FIGS. 8A and 8B), the good operability of the shutter 10 is maintained by the elastic force of the coil spring 61. Be done.

  When the shutter 10 is further moved in the closing direction and the shutter 10 reaches the closing position (see FIG. 9), the shutter 10 is provided, for example, on the guide rails 20, 30 or the right side frame 41 and the left side frame 42 The shutter 10 abuts against the stopper. As shown in FIG. 9, when the shutter 10 is in the closed position, the closing engagement claw 63 is located on the rear surface portion 3. On the other hand, the release engagement claw 62 is located on the upper surface 4 together with a part near the front end 13 of the shutter 10. Also, the opening 8 is closed.

  Thus, the shutter 10 is moved in the closing direction in the area from the closing contact position to the closing position where the closing engagement claw 63 starts to engage with the coil spring 61 (hereinafter also referred to as the closing engagement area). In this case, the closing engagement claw 63 and the coil spring 61 are engaged, and the coil spring 61 biases the shutter 10 in the opening direction via the closing engagement claw 63, and the operability of the shutter 10 is improved. There is.

  Further, even when the coil spring 61 is pulled by the closing engagement claw 63, the coil spring 61 is sandwiched between the shutter 10 and the coil spring guide frame 64, so that the runaway of the coil spring 61 is suppressed. It is possible to prevent the disengagement between the hook and the closing engagement claw 63.

  In the closing engagement region, the force urging the shutter 10 by its own weight in the closing direction is balanced with the force urging the shutter 10 in the coil spring 61 in the opening direction, or the shutter 10 of the coil spring 61 For example, the arrangement position of the closing engagement claw 63, the spring constant of the coil spring 61, the weight of the shutter 10, and the like are set so as to be larger than the force for biasing in the opening direction.

  When moving the shutter 10 in the opening direction from the closed position in which the opening 8 is closed, the coil spring 61 biases the shutter 10 in the opening direction against the force in the closing direction of the shutter 10 due to its own weight. Therefore, the operation of moving the shutter 10 in the opening direction is easy (see FIG. 9). While the shutter 10 is moving in the opening direction in the closing engagement area, the operation of the shutter 10 is facilitated by the engagement between the closing engagement claw 63 and the coil spring 61. Contrary to the movement of the shutter 10 in the closing direction, as the shutter 10 moves in the opening direction in the closing engagement area, the force in the closing direction by the weight of the shutter 10 becomes smaller, and a coil spring The force for biasing the shutter 10 in the opening direction 61 also becomes smaller.

  When the shutter 10 is further moved in the opening direction and the shutter 10 exceeds the closing engagement area (see FIGS. 8 (a) and 8 (b)), the closing engagement claw 63 and the coil spring 61 are separated and engagement therebetween As a result, the coil spring 61 does not bias the shutter 10.

  From this state, until the shutter 10 is further moved in the opening direction by the distance d between the open engagement claw 62 and the close engagement claw 63, the coil spring 61 is not pulled (unloaded state) (initial state) , And extends into the space between the release engagement pawl 62 and the closure engagement pawl 63.

  When the shutter 10 is further moved in the opening direction and reaches the opening contact position (see FIGS. 6A and 6B), the coil spring 61 is accommodated in the recess 62a of the opening engaging claw 62, and the opening engaging claw 62 engages with the coil spring 61 and acts as described above.

  As described above, in the shutter-equipped storage device 1, when the shutter 10 is moving in the open engagement area or the closed engagement area, the coil spring resists the force that biases the shutter 10 by its own weight. Since the shutter 61 is energized by the shutter 61, the operability of the shutter 10 is improved. Further, the collision noise of the shutter 10 generated when the shutter 10 is closed and opened is reduced.

  Also, in the area between the open engagement area and the closed engagement area, that is, in the area from the shutter intermediate position to the open abutting position and in the area from the shutter intermediate position to the closed abutting position When being moved in the closing direction, the coil spring 61 is not engaged with the release engagement claw 62 and the closure engagement claw 63, and is in a non-loaded state without being pulled. Thus, when the shutter 10 is moved in the opening direction or the closing direction in the area between the opening engagement area and the closing engagement area separated by the distance d, the coil spring 61 is in the opening direction or the closing direction. It does not extend in flexion, and it is in an initial condition of no load.

  As described above, in the shuttered storage device 1, when the shutter 10 is opened or closed, the coil spring 61 does not bend in the opening direction or the closing direction during the movement distance of the shutter 10 of the interval d. . Therefore, when the shutter 10 is moved from the closed position to the open position or moved from the open position to the closed position, the amount of deflection (elongation) in the opening direction or closing direction of the coil spring 61 It can be less than that.

  Therefore, in order to increase the width of the opening 8 in the opening and closing directions, the dimension in the longitudinal direction of the shutter 10 is increased, and the accommodation space of the article is maximized, and the rear end of the shutter 10 in the open position. Even in the housing apparatus 1 with a shutter such that a portion on the side of the portion 14 enters the lower surface portion 5, the opening engagement claw 62 and the closing engagement claw 63 engaged with the coil spring 61 in the opening and closing movement of the shutter 10 Therefore, the coil spring 61 can be prevented from being caught in the upper surface 4 or the lower surface 5 due to the opening and closing movement of the shutter 10. Thus, there is no need to deform the defined area (outline) of the shuttered storage device 1 in order to reduce the movement distance of the shutter 10, and the storage space of the articles of the shuttered storage device 1 is kept at a maximum. Can. Thereby, the opening / closing range of the shutter 10 can be enlarged while keeping the storage space of the articles of the storage device 1 with a shutter at the maximum.

  As described above, according to the storage device with a shutter 1 according to the embodiment of the present invention, the open / close range of the shutter 10 is achieved while improving the operability of the shutter 10 and keeping the storage space of articles as much as possible. Can be increased.

  In the storage device 1 with a shutter according to the embodiment of the present invention, the distance d between the release engagement claw 62 and the closure engagement claw 63 is set according to the material, weight, and size of the shutter 10. The operability of the opening direction and the closing direction of the shutter 10 can be kept constant.

  For example, the release engagement member and the closure engagement member are not limited to the release engagement claw 62 and the closure engagement claw 63 described above, and as described above, the coil spring 61 is used in the release engagement region and the closure engagement region respectively. It may be in any form that can engage with the For example, the engagement claws of a configuration in which the hook-like engagement part is ejected by the magnetic force may be used as the release engagement member and the closing engagement member. In this case, the coil spring 61 is assumed to be magnetized.

  Alternatively, the coil spring 61, the release engagement claw 62, and the closure engagement claw 63 may be magnetized, and the coil spring 61 may attract the release engagement claw 62 and the closure engagement claw 63 by magnetic force. Thereby, the engagement between the coil spring 61 and the release engagement claw 62 and the close engagement claw 63 can be made stronger. In this case, the coil spring guide frame 64 and the auxiliary frame 65 may be omitted.

  Moreover, an elastic member is not restricted to the above-mentioned coil spring 61, For example, rubber etc. may be sufficient. In addition, two coil springs 61 are vertically separated and provided in parallel as elastic members, and the open engagement claw 62 engages with the upper coil spring 61 from the closing direction side in the open engagement region and the lower coil spring 61 The closing engagement claw 63 may be engaged from the opening direction side in the closing engagement region. Thereby, the width in the longitudinal direction of the shutter 10 is increased, and the distance d between the release engagement claw 62 and the closure engagement claw 63 is set wide even when the movement distance of the shutter 10 is increased. Thus, the amount of extension of the coil spring 61 can be reduced, and the same effect as described above can be obtained.

  Further, in the storage device with shutter 1, the coil spring 61, the release engagement claw 62, and the close engagement claw 63 are provided on the rear side of the shutter 10 in the rear surface portion 3, and the coil spring guide frame 64 is The coil spring 61, the release engagement claw 62, and the close engagement claw 63 are provided on the rear side of the shutter 10 on the rear side, and the coil spring guide frame 64 is a shutter.
