Description

[Technical Field]

[0001] The present invention relates to a housing for an electronic device. [Background technology]

[0002] Patent Document 1 describes a cabinet for storing electrical and electronic equipment that can open both to the right and to the left without requiring special hinges or additional parts and that uses one type of door for housing electronic equipment. Patent Document 2 describes a support device for a left-right selective opening door that can open either to the left or to the right as desired using a hinge lock body embedded in the main body of a storage cabinet or the like. Patent Document 3 further describes a left-right dual-purpose pivot hinge that allows pivot-type hinges used on the top and bottom of the door to be used regardless of the opening and closing direction.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-105113 [Patent Document 2] Japanese Patent Application Publication No. 5-302462 [Patent Document 3] Japanese Patent Application Laid-Open No. 2008-038345 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional cabinets for storing electrical and electronic equipment that use the hinge receiving brackets described in Patent Document 1, which allow the shaft to be inserted from either the top or bottom, i.e., removable hinges, when assembling and installing the cabinet on site, it is necessary to easily remove long doors and move the doors up and down to work, but there is a problem in that it is sometimes difficult to secure work areas above and below.

[0005] Furthermore, in the case of conventional storage cabinet doors that use the pivot-type hinges described in Patent Documents 2 and 3, there was a problem in that the middle part of the door was weak due to the security requirements (the mechanism of the lock must not be visible, it must not be opened with bare hands, it must not be opened using everyday office supplies, it must not be opened with ordinary tools without leaving clear traces, etc.).

[0006] Furthermore, in the case of a typical right-opening door, if the door is installed in a way that does not allow for a maintenance area on the left side, such as a wall, the locking function cannot be utilized and the door may have to be left removed during operation, which creates the problem of not fulfilling the security function.

[0007] The present invention has been made in consideration of the above-mentioned problems of the conventional technology, and aims to provide a housing that allows for easy attachment and detachment of doors during on-site assembly and installation, while maintaining the security function of the doors. [Means for solving the problem]

[0008] The housing of the present invention is a housing having a door and a mounting frame in an opening in which the door fits and is closed, characterized in that it has a pair of pivot hinges provided on the door and the mounting frame on one axis so that the door can rotate around the axis relative to the mounting frame, and an engagement portion provided on the door between the pivot hinges and which catches on the mounting frame when the door is closed. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide a housing that can easily attach and detach a door during installation and maintain the security function of the door. [Brief explanation of the drawings]

[0011] Hereinafter, with reference to the drawings, an embodiment of the housing of the present invention will be described using a slim rack in a business digital mobile radio telephone system as an example. Note that in the embodiments, components having substantially the same functions and configurations are designated by the same reference numerals, and redundant explanations will be omitted.

[0012] (Configuration explanation) Fig. 1 is a schematic perspective view showing a slim rack 100 according to an embodiment of the present invention. Fig. 2 is a schematic rear view showing the inside of the door of the slim rack according to this embodiment.

[0013] In addition, in Figures 1 to 3, connection holes for passing electronic devices, power supplies, electronic components, cables between electronic components, external power supply cables, input / output cables, antennas, etc. housed in the slim rack are omitted and not shown.

[0014] 1, a slim rack 100 in a business digital mobile radio telephone system is composed of a rack body 110 and an opening / closing door 120 attached to its front opening. The body 110 is closed by the opening / closing door 120 fitting into a door mounting frame 111.

[0015] As an example, the slim rack 100 is divided into three sections, an upper section, a middle section, and a lower section, for storing functional units. The opening and closing doors 120 of each section are provided with ventilation holes. In addition, a rear cover (not shown) on the rear side of the main body 110 is provided with ventilation holes.

[0016] As shown in FIG. 1, a right-opening door 120 has a security lock 140 attached to the center of the door in the vertical direction.

[0017] 2, in the opening and closing door 120, the security lock 140 is connected to the middle drive link fastener 126C via a central fixed rotation fulcrum 129C on the rear surface (inside) of the door, and when the lock 140 is turned with a key 141, the drive link fastener 126C rotates together with the rotation axis (fixed fulcrum 129C). The drive link fastener 126C is connected to the lock 140 which is the fixed fulcrum 129C, the intermediate link 130 which is connected to the movable rotation fulcrums 131U, 131C, 131L, the upper and lower fixed rotation fulcrums 129U, 129L, and the upper and lower driven link fasteners 126U, 126L by a closed-loop link mechanism.

[0018] The right-opening door 120 is provided with a pair of hinges (pivot hinges in this example) 124, 125 for pivoting to open and close at the right positions on the top and bottom ends, and a locking portion 127 (engagement portion) that catches on the door mounting frame 111 of the main body 110 when closed, at a central concentric position on the pivot hinge shaft between the two hinges. The pivot hinges 124, 125 are made up of rotating shaft bodies (fulcrum levers PB124, PB125) located on both ends of the short side of the door 120 in the pivot hinge axial direction along the vicinity of the long side of the door 120, and bearings BR124, BR125 located on both short sides of the door mounting frame 111 that hold these rotating shaft bodies around the pivot hinge shaft so that the door can be opened and closed freely. That is, a pair of pivot hinges 124, 125 are provided on the door 120 and the door mounting frame 111 on the pivot hinge axis so that the opening and closing door 120 rotates around the pivot hinge axis relative to the door mounting frame 111. Here, a spring-type pivot hinge is used as the pivot hinge 124, and one whose fulcrum shaft (lever) can be manually compressed and automatically extended is used. The pivot hinge 125 may also be of the spring type.

[0019] In this way, the opening and closing door 120 has a lock 140 that is provided on the rotating end side farthest from the pivot hinge axis, extending from the front side to the back side of the opening and closing door 120, and that locks and unlocks the door mounting frame 111 of the opening and closing door 120.

[0020] In addition, the opening / closing door 120 has a first link part (lock 140, which is a fixed rotation fulcrum, and movable rotation fulcrum 131C) at its rotation end side, which is provided on the back side of the opening / closing door 120 and operates in conjunction with the locking and unlocking of lock 140.

[0021] In addition, the opening / closing door 120 has a second link portion (intermediate link 130, movable rotation fulcrums 131U, 131L, rotation fixed fulcrums 129U, 129L) on the rotating end side, which is provided on the back side of the opening / closing door 120 and forms a closed loop structure with the first link portion.

[0022] In addition, the opening / closing door 120 has a latch portion (fasteners 126C, 126U, 126L) on the back side of the opening / closing door 120 at its pivot end side, which is linked to the second link portion and hooks onto the door mounting frame 111 to lock and unlock without hooking onto the door mounting frame 111.

[0023] At least one of the latch portions (fastener 126C) is disposed in a portion of the door 120 facing the engaging portion 127 (the intermediate portion between the pivot hinges 124 and 125).

[0024] As shown in Fig. 3, a pair of bearings BR124, BR125 for fitting hinges 124, 125 at the right positions of the upper and lower ends of the main body 110 and door mounting frame 111 of the slim rack 100 are provided. A catch surface 114C (engagement surface) on which a locking part 127 catches when the door is closed is provided on the inner surface on the right side of the door mounting frame 111 at a central concentric position between the upper and lower bearings (pivot hinges 124, 125).

[0025] As shown in Figure 3, the left inner surface of the main body 110 and door mounting frame 111 of the slim rack 100 is provided with hooking surfaces 114U, 114C, and 114L for engaging the upper, middle, and lower fasteners 126U, 126C, and 126L of the right-opening opening / closing door 120 shown in Figure 2.

[0026] 3, furthermore, so that the hinges 124, 125, the locking portion 127, and the stoppers 126U, 126C, 126L can engage with each other even when the door 120 is turned upside down, hooking surfaces 114U, 114C (already mentioned), and 114L are provided on the right inner surfaces of the main body 110 of the slim rack 100 and the door mounting frame 111, and a pair of bearings BR124, BR125 are provided at the left positions of the top and bottom ends of the door mounting frame 111. The hooking surfaces 114C on the left and right inner surfaces of the door mounting frame 111 serve as locking means for the stoppers 126C and the locking portion 127, whether the door 120 is a right-opening door or a left-opening door 120.

[0027] Therefore, in the case of the left-opening door 120, the right-opening door 120 is rotated 180 degrees up and down, and the hinges 124, 125 are fitted into the left door rotation fulcrum holes (bearings BR124, BR125) of the door mounting frame 111 of the main body 110.

[0028] In this way, the opening / closing door 120 is a left-opening or right-opening door, and in the door mounting frame 111, each of the portions (hooking surfaces 114U, 114C, 114L) that are hooked onto the engagement portion 127 and latch portion (fasteners 126U, 126C, 126L) of the opening / closing door 120 is formed in a position that is approximately symmetrical to each other in terms of vertical and horizontal positional relationships.

[0029] (Explanation of operation) The door opening and closing 120 is as follows.

[0030] To unlock the right-opening door 120, the lock 140 is rotated clockwise with the key 141, and as shown in Figure 2(A), the driving link fastener 126C, the driven link fastener 126U and the driven link fastener 126L rotate inward along with the rotation axis of the intermediate link 130, thereby avoiding the frame catch surfaces 114C, 114U and 114L of the door mounting frame 111 of the main body 110, thereby unlocking the door.

[0031] As shown in Fig. 2(B), by locking (rotating left) the lock 140, the driving link fastener 126C locks the central frame hooking surface 114C, and the upper and lower driven link fasteners 126U, 126L lock the upper and lower frame hooking surfaces 114U, 114L of the door mounting frame 111 of the main body 110. At this time, as shown in Fig. 4, the locking part 127 serving as an engaging part protrudes from the vicinity of the pivot hinge axis on the surface facing the opening of the door 120, and therefore, when the opening and closing door 120 rotates from the open position to the closed position, it moves around the pivot hinge axis beyond the pivot hinge axis and engages with the frame hooking surface 114C serving as a locking surface provided on the door mounting frame 111, restricting movement of the opening and closing door 120 in a direction away from the housing 110 when the opening and closing door 120 is in the closed position. That is, when the door is locked, the locking portion 127 is caught on the frame catch surface 114C at the middle part of the door mounting frame 111 of the main body 110, which acts as a clamp on the center part of the closed opening / closing door 120, preventing the opening / closing door 120 from easily bending or deforming from the center part, thereby ensuring security.

[0032] The lock play (play) of the upper and lower driven link fasteners 126U, 126L is set larger than that of the middle driving link fastener 126C, which corresponds to the surface finish of the opening and closing door 120 and improves the quality of the locking operation.

[0033] Next, the switching from the right-opening door 120 to the left-opening door 120 is as follows.

[0034] As shown in Figure 5, when the right-opening door 120 is unlocked and opened, the locking portion 127 is released from the door mounting frame 111 (hooking surface 114C) of the main body 110, and by pulling down the fulcrum lever PB124 of the pivot hinge 124 toward the inside of the door 120, the engagement with the door rotation fulcrum hole (bearing BR124) can be released, allowing the specified work and operations to be performed.

[0035] If the right-opening door 120 (Figure 6(A)) that has been lowered from the door mounting frame 111 of the main body 110 is rotated 180 degrees upside down to become the left-opening door 120 (Figure 6(B)), it will be in a state where it can be replaced with the left-opening door 120.Therefore, the left-opening door 120 can be turned over and the fulcrum lever PB124 of the pivot hinge 124 retracted inside the door 120, and the fulcrum levers PB124, PB125 of the pivot hinges 124, 125 can be fitted into the door rotation fulcrum holes (bearings BR124, BR125) on the left side of the door mounting frame 111 of the main body 110 and installed as shown in Figure 7.

[0036] (Explanation of effect) As described above, according to this embodiment, the following effects can be obtained.

[0037] (1) By having the rotational movement (turning) of the opening and closing door 120 be exclusively handled by the two upper and lower pivot hinges 124, 125, measures to prevent complications in the rotational movement are eliminated, and the deterioration in security caused by this elimination is compensated for by the locking section 127 when the door is closed, thereby ensuring the required quality and manufacturability.

[0038] (2) By arranging the engagement parts of the opening / closing door 120 (locking part 127, pivot hinges 124, 125, fasteners 126C, 126U, 126L) evenly on the door mounting frame 111 of the main body 110 in all directions, it is possible to change the setting of one opening / closing door 120 to either a right-opening opening / closing door 120 or a left-opening opening / closing door 120 depending on the local conditions.

[0039] (3) To make this replacement possible, the upper, middle, and lower fasteners 126U, 126C, and 126L are connected by a closed-loop link mechanism, which allows the three points to operate simultaneously, thereby improving the locking quality.

[0040] (4) The same level of security can be ensured whether the door is installed on the left or right side. Furthermore, when replacing the left or right door, no tools or replacement parts are required, and the replacement can be done manually.

[0041] Although the present embodiment has been described as being applied to the door of a slim rack of a business digital mobile radio system, it can also be applied to a device having a revolving door with ventilation holes. [Explanation of symbols]
