Description

[Technical field]

[0001] The present invention relates to an equipment storage box with an open / close detection function. [Background technology]

[0002] An equipment storage box equipped with a detector that detects whether a door is open or closed is in use. As described in Patent Document 1, such a detector detects the contact between a switch and the front part of the door, and sounds a buzzer when the contact is detected. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 07-023911

[0004] However, even if the switch unit is to be abutted against the front part of the door, it may be difficult to adjust the abutment because it is far away from the door axis. This is because the engagement state of the axis may become inappropriate due to dimensional errors in the molding of the box body or the door, or the door may warp, making it difficult to adjust the mounting position of the switch unit. In addition, if the stroke of the switch unit is short, there is a risk that the switch unit cannot be pressed due to dimensional errors in the door, so a detection unit with a long stroke of the switch unit must be used, which causes a problem of the detection unit becoming large. In addition, when the door is made of resin, dimensional errors tend to be particularly large. Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors of the present invention have thoroughly investigated this issue and have attempted to solve it. The problem that the present invention aims to solve is to provide an equipment storage box that can properly detect the opening and closing of the door even if the switch unit is small in size. [Means for solving the problem]

[0006] In order to solve the above problems, there is provided an equipment storage box with an open / close detection function, the equipment storage box including a box body with an opening through which an equipment can be put in and taken out, and a door that is pivotally supported so as to be able to cover the opening of the box body, and a detection unit with a switch unit used to detect whether the door is open or closed, the detection unit being formed on the axis side of the storage box, and the switch unit coming into contact with a side portion of the door when the door is closed. Let us assume that.

[0007] It is also preferable that when the door is closed, the inner surface of the side portion of the door is positioned substantially flush with the inner surface of the side surface of the box body.

[0008] It is also preferable that the detection unit be fixed to a side surface of the box body.

[0009] It is also preferable that the detection section is provided with a spacer that abuts against the side surface of the box body.

[0010] It is also preferable that the box body be provided with a protruding piece for abutting against the door when the door is closed, and that one end of the spacer be positioned within a recess whose bottom surface is the protruding piece when the door is closed. Effect of the Invention

[0011] The present invention makes it possible to provide an equipment storage box that can properly detect whether a door is open or closed even if the switch unit is small in size. [Brief description of the drawings]

[Figure 8] The dashed line in the diagram shown in Figure 4 indicates that when the door is closed, the inner surface of the side portion of the door is positioned approximately on the same plane as the inner surface of the side of the box body. [Figure 9] 13 is a diagram showing an example in which a detection unit is attached to the bottom surface of a box body. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The following describes an embodiment of the invention. As can be seen from Figs. 1 to 4, the device storage box 1 with open / close detection function of this embodiment includes a storage box including a box body 10 with an opening 12 through which a device 9 can be put in and taken out, a door 20 pivotally supported so as to cover the opening 12 of the box body 10, and a detection unit 30 with a switch unit 30a used to detect the opening and closing of the door 20. The device storage box 1 with open / close detection function is configured such that the detection unit 30 is formed on the shaft 41 side of the storage box, and when the door 20 is closed, the switch unit 30a comes into contact with the side portion 23 of the door 20. Here, as can be seen from Fig. 5, the farther the door 20 is from the shaft 41, the greater the rotation distance when moving from an open state to a closed state. Generally, it is necessary to adjust the mounting position of the detection unit 30 to compensate for dimensional errors of the housing, and the farther the detection unit 30 is positioned from the axis 41, the greater the effect of the dimensional errors. However, since the movement distance of the door 20 is small on the axis 41 side, the effect of the possible dimensional errors can be suppressed. Therefore, it is possible to provide an equipment storage box 1 that can properly detect the opening and closing of the door 20 even if the switch unit 30a is small.

[0014] In the embodiment, when the door 20 is opened and the switch unit 30a is in a predetermined position, the buzzer 33 provided in the detection unit 30 sounds. As shown in Fig. 3 and Fig. 4, when the door 20 is closed, the switch unit 30a is moved by receiving a load from the side surface portion 23 of the door 20, and the buzzer 33 does not sound, but as shown in Fig. 6 and Fig. 7, the switch unit 30a moves automatically by being released from the load from the side surface portion 23 of the door 20, and when it moves to a predetermined position, the buzzer 33 sounds.

[0015] Here, an overview of the equipment storage box 1 in the embodiment will be described. Typical examples of equipment 9 stored in the equipment storage box 1 include a measurement unit, electrical equipment of a HUB, electronic equipment such as a server or communication device, and medical equipment such as an AED, but the following description will be given taking an equipment storage box 1 that stores medical equipment as an example. In the embodiment, a mounting plate 19 is provided on the box body 10, and the equipment 9 is fixed to the mounting plate 19 or the like.

[0016] The device storage box 1 of the embodiment includes a storage box including a box body 10 with an opening 12 through which the device 9 can be put in and taken out, and a door 20 pivotally supported so as to be able to cover the opening 12 of the box body 10. The box body 10 and the door 20 of the storage box in the embodiment are manufactured using resin. The door 20 is pivotally supported on one side surface 13 of the box body 10, and includes a locking portion 50 that can be hooked onto a locking portion 60 provided on the other side surface 13 of the box body 10, and a locking portion 28 that can be locked to the locking locking portion 18. In the embodiment, the door 20 is provided with a handle 29, and the locking portion 28 and the locking portion 50 are provided on a part of the handle 29. In addition, the locking portion 28 is provided with a locking portion 28a into which a key (not shown) is inserted on the front side of the door 20, and the locking portion 28 can be rotated by rotating the key inserted into the locking portion 28a.

[0017] Door 20 has a front portion 22 facing opening 12, and a side portion 23 extending at a substantially perpendicular angle to front portion 22. By forming door 20 with a substantially U-shaped cross section using front portion 22 and side portion 23, door 20 can be closed even if an object protruding somewhat from box body 10 is stored inside. In other words, because door 20 has a recessed back surface, the space created inside the storage box when door 20 is closed can be made larger than the space provided in box body 10.

[0018] The side surface portion 23 in the embodiment is configured to extend in the same direction as the side surface 13 of the box body 10. More specifically, when the door 20 is closed, the inner surface of the side surface portion 23 of the door 20 is configured to be positioned substantially on the same plane as the inner surface of the side surface 13 of the box body 10 (see FIG. 8).

[0019] In addition, a detection unit 30 equipped with a switch unit 30a that detects the opening and closing of the door 20 is attached to the box body 10. The detection unit 30 of the embodiment is provided on the side surface 13 of the box body 10, and is fixed to the side surface 13 on the side of the shaft unit 41 that serves as the pivot shaft of the door 20. This makes it possible to prevent the detection unit 30 from having a complex structure.

[0020] The detection unit 30 in the embodiment includes a board 32, a buzzer 33, a limit switch 34, a battery mounting portion 35 for mounting a battery that supplies power to the buzzer 33, etc. In the embodiment, the buzzer 33, the limit switch 34, the battery mounting portion 35, etc. are mounted on the board 32. The switch portion 30a provided on the limit switch 34 is arranged so that it can be moved by opening and closing the door 20, but in the embodiment, it is arranged so that it can move in the left-right direction.

[0021] 3 is configured such that the surface of the substrate 32 on which the limit switch 34 is attached faces the side surface 13 on which the shaft portion 41 is formed. Therefore, when viewed from the center of the box body 10, the limit switch 34 is covered by the substrate 32. This makes it possible to prevent erroneous operation of the limit switch 34. The electronic circuit provided on the substrate 32 is also provided on the surface facing the side surface 13 on which the shaft portion 41 is formed.

[0022] Incidentally, within the box body 10, the vicinity of the side surface 13 where the shaft portion 41 is formed is a location that is likely to become dead space where the device 9 to be stored is not placed. By utilizing this location as the location of the detection portion 30, the internal space of the device storage box 1 can be effectively utilized.

[0023] 8, when the door 20 is closed, the inner surface of the side surface portion 23 of the door 20 is configured to be positioned substantially flush with the inner surface of the side surface 13 of the box body 10. Therefore, even when the door 20 is in an open state, it is easy to guess the positional relationship between the switch unit 30a and the side surface portion 23 of the door 20 when the door 20 is closed, making it easy to adjust the position of the switch unit 30a.

[0024] Moreover, the detection unit 30 of the embodiment includes a spacer 38 that can come into contact with the side surface 13 of the box body 10. This spacer 38 is disposed near the limit switch 34, and can contribute to suppressing the deflection of the substrate 32 when the door 20 is closed and suppressing the load applied to the limit switch 34.

[0025] In the embodiment, the box body 10 is provided with the protruding piece 15 for abutting against the door 20 when the door 20 is closed, and one end of the spacer 38 is located in the recess in which the protruding piece 15 becomes the bottom surface 14 when the door 20 is closed. In this manner, the spacer 38 can be disposed near the entrance of the opening 12 of the box body 10. Therefore, the spacer 38 can be disposed near the limit switch 34. Also, the end of the substrate 32 can be supported by the spacer 38.

[0026] Incidentally, the attachment position of the detection unit 30 is not limited to the side surface 13 of the box body 10. For example, as can be seen from Fig. 9, the detection unit 30 may be attached to the bottom surface 14 of the box body 10. Even in this case, the detection unit 30 is formed on the shaft portion 41 side of the storage box.

[0027] Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be embodied in various forms. For example, the detection unit may be attached to the ceiling surface of the box body. [Explanation of symbols]
