Description

[Technical Field]

[0001] The present invention relates to an opening angle restricting structure that is arranged near one case formed so that the other case can be opened and closed relative to the other case, and that restricts the opening angle of the other case. [Background technology]

[0002] As a structure in which one case opens and closes relative to the other case, for example, the opening and closing structure described in Patent Document 1 is known. The opening and closing structure disclosed in Patent Document 1 includes a lower case having a pivot shaft at one end and an upper case having a bearing hole into which the pivot shaft is inserted. The upper case is supported by the lower case so as to be able to open and close freely by inserting the pivot shaft into the bearing hole of the upper case. Meanwhile, the lower case is provided with an elastic piece, and the upper case is provided with a retainer with which the elastic piece engages. This opening and closing structure prevents the upper case from opening to an angle of more than 90 degrees by engaging the elastic piece of the lower case with the retaining body of the upper case, and also prevents damage caused by opening too far.

[0003] [Patent Document 1] Patent No. 4626325 Summary of the Invention [Problem to be solved by the invention]

[0004] As described above, in conventional opening and closing structures, a structure that restricts the opening angle is often formed inside the case to prevent damage caused by opening beyond a certain angle. However, this opening and closing structure is often built into the case structure itself or formed as an integral part, and it has been difficult to incorporate it into commercially available case units that already have an opening and closing structure.

[0005] An object of the present invention is to provide an opening angle restriction structure that can restrict the opening angle of a case unit that already has an opening and closing structure formed therein. [Means for solving the problem]

[0006] In order to achieve this object, the opening angle control structure of the present invention is an opening angle control structure that is provided inside an electronic device that is mounted on a wall, together with an open / close type case unit, and is equipped with an opening angle control member that controls the opening angle of the case unit, wherein the case unit stores electronic components inside and has a first case that extends in the vertical direction while being parallel to the wall, and a second case that is attached to the lower end of the first case so as to be able to open and close horizontally via a horizontal opening / closing axis, and the opening angle control member is positioned so as to block the movement path of the second case when the second case is opened, and has at least one abutment portion against which the second case abuts when the second case reaches a predetermined opening angle, and the abutment portion is formed smaller than the second case in the axial direction of the opening / closing axis.

[0007] In the opening angle restriction structure of the present invention, the opening angle restriction member has a base that extends in the axial direction of the opening / closing axis and in the vertical direction near the bottom of the first case, the abutment portion is formed in a plate shape that extends in the vertical direction and in a direction perpendicular to the wall and is protruded from the base, and a sloped surface is formed in the portion of the base adjacent to the abutment portion that gradually slopes toward the wall as it extends upward.

[0008] In the opening angle control structure of the present invention, the predetermined opening angle may be an angle at which the electronic component placed on the second case in an open state is held on the second case without slipping off. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide an opening angle restricting structure that can restrict the opening angle of a case unit that already has an opening and closing structure formed therein. [Brief explanation of the drawings]

[0011] Hereinafter, an embodiment of an opening angle restriction structure according to the present invention will be described in detail with reference to FIGS. The electronic device 1 shown in FIG. 1 is intended to be attached to a wall 2 extending in the vertical direction, and is configured as a housing 5 consisting of a box-shaped case body 3 attached to the wall 2 and a cover 4 that closes the opening of the case body 3. In the following, directions are indicated in the direction as seen when facing the electronic device 1. That is, the upper side of FIG. 1 is the upper side of the electronic device 1, the upper right side of FIG. 1 is the right side of the electronic device 1, and the lower left side of FIG. 1 is the left side of the electronic device 1. Furthermore, the lower right side of FIG. 1 is the front side of the electronic device 1, and the upper left side of FIG. 1 is the rear side of the electronic device 1.

[0012] The case body 3 is formed in a rectangular cylindrical shape with a bottom that opens in a direction away from the wall 2, and is fixed to the wall 2 with a plurality of fixing screws (not shown). The cover 4 is formed in a rectangular cylindrical shape with a bottom that opens toward the case body 3, and is attached to the case body 3 in an openable, closable, and detachable manner. Inside the housing 5, there are provided a main board 7 on which circuit components 6 are mounted, a sub-board 8 arranged in front of the main board 7 in a position parallel to the main board 7, a battery storage box 9, etc.

[0013] The sub-board 8 is provided with an openable / closable case unit 11 according to the present invention, and has circuit components (not shown) mounted thereon. The sub-board 8 is fixed to a plurality of support posts 12 erected on the case body 3 with fixing screws 13. A battery storage box 9 is disposed below and near the sub-board 8. The battery storage box 9 is also fixed to the case body 3. The battery storage box 9 stores a battery 14 that serves as the power source for the electronic device 1.

[0014] As shown in Fig. 2, case unit 11 houses SIM card 15 as an electronic component therein. As shown in Fig. 3, case unit 11 has a first case 16 that extends in the vertical direction parallel to sub-board 8 (parallel to wall 2 and main board 7), and a second case 18 that is attached to the lower end of first case 16 via a horizontal opening / closing shaft 17 (see Fig. 5) so as to be able to open and close horizontally.

[0015] 2, when the SIM card 15 is stored in the case unit 11, the second case 18 is erected (closed) so as to extend in the vertical direction. The second case 18 is configured to be movable in the vertical direction relative to the first case 16 while erected in this manner. In this case unit 11, by sliding the second case 18 upward with the SIM card 15 sandwiched between the first case 16 and the second case 18, the second case 18 is fixed to the first case 16 and maintained in the closed state.

[0016] From this locked state, the second case 18 is lowered and the upper end portion of the second case 18 is tilted forward around the lower end portion (opening / closing shaft 17), thereby opening the second case 18 as shown in Fig. 3. An opening angle restriction structure 21 is provided near the lower portion of the case unit 11 to abut against the second case 18 and restrict the opening angle of the case unit 11. The opening angle restriction structure 21 is constructed using the battery storage box 9 arranged near the bottom of the case unit 11, and has an opening angle restriction member 22 (see Figure 2) formed from a part of the battery storage box 9.

[0017] As shown in FIG. 2 , the opening angle restricting member 22 is composed of a base 23 that extends in the left-right direction (the axial direction of the opening / closing shaft 17) and the up-down direction near the bottom of the first case 16, and an abutment portion 24 that protrudes from the base 23. The base 23 is disposed near the bottom of the first case 16. In this embodiment, the base 23 essentially functions as a bracket for fixing the battery storage box 9 to the case body 3. More specifically, as shown in FIG. 4 , the base 23 is placed on the support pillar 12 of the case body 3 and is fixed to the support pillar 12 by a fixing screw 25 that is screwed into the support pillar 12. The support pillar 12 penetrates the main board 7 and the sub-board 8 and extends to the base 23. A cylindrical body 23a is provided on the base 23, which sandwiches the sub-board 8 between the support pillar 12 and a step portion 12a of the support pillar 12.

[0018] In this embodiment, the abutment portions 24 are formed in a plate shape and are arranged so as to block the movement path of the second case 18 when the second case 18 is opened, as shown in Fig. 5. The abutment portions 24 are formed in a plate shape extending up and down and in a direction perpendicular to the wall 2 (front-rear direction), and are formed integrally with the base 23 so as to extend forward from the base 23. In this embodiment, three plate-shaped abutment portions 24 are provided in a protruding manner on the base 23. That is, the abutment portions 24 are arranged at both ends and the center of the movement path of the second case 18 in the axial direction (left-right direction) of the opening-closing shaft 17. Each abutment portion 24 is smaller than the second case 18 in the axial direction of the opening-closing shaft 17.

[0019] Furthermore, the abutment portion 24 is configured so that the second case 18 abuts against it when the second case 18 reaches a predetermined open angle. The predetermined open angle here is an angle at which, when the SIM card 15 is placed on the second case 18 in the open state as shown in Fig. 6, the SIM card 15 is held on the second case 18 without slipping off.

[0020] 2, the portion of the front surface of the base 23 adjacent to the abutment portion 24 is formed by an inclined surface 26. In the base 23 according to this embodiment, the inclined surface 26 is formed on both the left and right sides of the abutment portion 24 that is located in the middle of the three abutment portions 24. 6, the inclined surface 26 is inclined so as to gradually approach the wall 2 (toward the rear) as it extends upward. More specifically, the inclined surface 26 is inclined at an angle α with respect to an imaginary line L1 extending vertically when viewed from the axial direction (left-right direction) of the opening / closing shaft 17.

[0021] The reason why the inclined surface 26 is formed on the base 23 in this manner is that the electronic device 1 may be attached to a wall surface 2a above a door 27, for example, as shown in Fig. 7. Even when the electronic device 1 is attached at such a high position, the inclined surface 26 formed on the base 23 allows an operator 28 to look up from diagonally below and see the entire case unit 11 without being obstructed by the base 23. That is, the angle α of the inclined surface 26 with respect to the vertical direction is close to the angle β of the line of sight L2 of the operator 28 operating the second case 18 with respect to the vertical direction, as shown in Fig. 7.

[0022] In the opening angle restriction structure 21 configured in this manner, the opening angle of the second case 18 of the case unit 11 is restricted by the second case 18 abutting against the abutment portion 24 of the battery storage box 9. Therefore, according to this embodiment, it is possible to provide an opening angle restriction structure that can restrict the opening angle of the case unit 11 that already has a structure for opening and closing.

[0023] Furthermore, contact portion 24 is formed smaller than second case 18 in the axial direction of opening / closing shaft 17. Therefore, second case 18 is not hidden by contact portion 24 when opening second case 18, so even when electronic device 1 is mounted in a high position and second case 18 is opened or closed while looking up from diagonally below, the operation can be performed while viewing both second case 18 and contact portion 24. As a result, second case 18 can be opened or closed easily and correctly without being opened excessively.

[0024] The opening angle restricting member 22 according to this embodiment has a base 23 that extends in the axial direction of the opening / closing shaft 17 and in the vertical direction near the bottom of the first case 16. The abutting portion 24 is formed in a plate shape that extends in the vertical direction and in a direction perpendicular to the wall, and is provided so as to protrude from the base 23. A sloped surface 26 is formed in the portion of the base 23 adjacent to the abutting portion 24, which slopes gradually toward the wall 2 as it extends upward. Therefore, when inserting or removing SIM card 15 in electronic device 1 that is installed at a high position, worker 28 can perform the work while viewing the entire case unit 11 from diagonally below without his / her line of sight L2 being obstructed by base 23. Therefore, it is possible to provide an opening angle restriction structure that improves the workability of work that involves opening and closing case unit 11.

[0025] In the above-described embodiment, an example has been shown in which three contact portions 24 are used. However, the present invention is not limited to such a limitation, and the number of contact portions 24 can be changed as appropriate. That is, it is possible to provide only one contact portion 24, or to provide four contact portions 24. The shape of the contact portion 24 is not limited to a plate shape, and it may be columnar.
