Description

  The present invention relates to a fall prevention mechanism for an electronic device.

  2. Description of the Related Art Conventionally, when an electronic device is installed, a technique for preventing the electronic device from overturning by adopting a structure for attaching a stabilizer for stably installing the electronic device has been used. However, when the electronic device is tilted, the stabilizer is deformed by the weight of the electronic device, and it is insufficient to prevent the electronic device from falling. In order to solve such a problem, a structure in which a reinforcing metal fitting as shown in FIGS. 4 and 5 is attached to a stabilizer has been proposed.

  FIG. 4 is a schematic diagram showing a conventional electronic device overturn prevention mechanism. In order to prevent the electronic device 1 from overturning, an L-shaped bend is provided on the front surface (left side of FIG. 4) of the electronic device 1. A shaped stabilizer 2 is attached. Here, when the electronic device 1 is tilted, the stabilizer 2 is fixed to the bottom surface of the electronic device 1 in order to prevent the stabilizer 2 from being deformed and to further enhance the fall prevention function of the electronic device 1. The reinforcing metal fitting 5 is attached by screwing.

  However, in the case of the technique as shown in FIG. 4, it is necessary to fix the reinforcing bracket 5 with a screw from the inside of the bottom surface of the electronic device 1, so that the electronic device mounted in the electronic device 1 at the time of installation work of the electronic device 1 is used. It was necessary to take out the device once and perform screw tightening work. As a result, there has been a problem that a great amount of man-hours are required for installation work and transfer work of the electronic device 1.

  FIG. 5 is a schematic view showing a structure different from that of FIG. 4 of the conventional electronic device overturn prevention mechanism. In order to prevent the electronic device 1 from overturning, the front side of the electronic device 1 (left side in FIG. 5) is shown. As in the case of FIG. 4, the L-shaped bent stabilizer 2 is attached, but the attachment position of the reinforcing bracket is different from that in FIG. 4. In other words, in FIG. 5, the stabilizer 2 has a bottom surface portion of the electronic device 1 in order to prevent the stabilizer 2 from being deformed when the electronic device 1 is tilted and to further enhance the fall prevention function of the electronic device 1. The reinforcing metal fitting 5A is attached to the side surface of the electronic device 1 by screwing. Similarly, Japanese Patent Application Laid-Open No. Hei 6-177549 discloses a structure in which an overhang preventing portion is provided on both sides of the bottom of the housing.

However, in the case of the technique as shown in FIG. 5, it is necessary to fix the reinforcing bracket 5 </ b> A with a screw from the side of the electronic device 1, and therefore, when installing adjacent to another electronic device, the screw is fixed to the stabilizer 2. There was a problem of becoming impossible.
JP-A-6-177549 (page 2)

  As described above, the conventional technology for preventing overturning of electronic equipment has a problem that the stabilizer attached to stably install the electronic equipment is deformed and the effect of preventing the overturning is insufficient.

  In other words, when the reinforcing bracket is not used, when the electronic device mounted on the electronic device is pulled out for maintenance, the stabilizer may bend due to the weight of the electronic device, and the function of preventing the electronic device from falling may be deteriorated. . That is, when a heavy object (electronic device) in the electronic device is pulled out, deflection of the screw fixing surface of the stabilizer occurs due to the movement of the center of gravity, and the electronic device may fall down.

  For this reason, as shown in FIGS. 4 and 5, a technique for further adding the reinforcing metal members 5 and 5 </ b> A to the stabilizer 2 has been proposed. That is, the metal fittings 5 and 5A are further added to the stabilizer 2 to increase the number of fixing portions to the electronic device 1, thereby enhancing the function of preventing the electronic device 1 from falling.

  However, as described above, there are problems in any of the techniques, and no fundamental solution has been reached. That is, in the case of FIG. 4, it is necessary to fix the reinforcing metal fitting 5 with a screw from the inner surface of the electronic device 1, so that it is necessary to temporarily lower the electronic device mounted in the electronic device 1 and install the stabilizer 2. Further, in the case of FIG. 5, since there is a screw fixing portion on the outer surface of the electronic device 1, there is a problem that other devices installed adjacently become in the way and the screw cannot be fixed.

  The present invention has been made in view of such problems, and by using a stabilizer and a fixture together to enhance the function for stable installation, the electronic device can be prevented from falling over more reliably. Its purpose is to provide a mechanism.

  It is another object of the present invention to provide an electronic device overturn prevention mechanism that can reduce the cost by simplifying the stabilizer structure and improve the maintainability by facilitating the attachment / detachment of the stabilizer.

  In order to solve the above-described problems, the electronic device toppling prevention mechanism according to the present invention employs the following characteristic configuration.

(6) The falling of the fixing tool (5) The electronic device overturn prevention mechanism according to (5), wherein the screw is tightened and loosened from the front of the electronic device when the portion is attached to and detached from the rising portion of the stabilizer.

  According to the electronic device overturn prevention mechanism of the present invention, the following effects can be obtained.

  The first effect is that it is possible to reduce the cost as a mechanism for preventing the electronic equipment from toppling over. The reason is that it is possible to configure a fall prevention mechanism by adopting only two parts having a simple structure of a stabilizer and a fixture.

  The second effect is an improvement in maintainability. The reason is that the stabilizer of the present invention can be attached and detached from the front of the electronic device, and as a result, during the construction at the time of installation of the electronic device, the stabilizer is preliminarily attached and the construction time is restricted. This is because it is not necessary.

  The third effect is that the stabilizer and the fixture can be easily attached and detached by screwing or loosening the screw from the front of the electronic device, so that the number of work steps can be reduced even in the transfer work of the electronic device.

  Preferred embodiments of the electronic device overturn prevention mechanism according to the present invention will be described below with reference to the accompanying drawings.

(Features of the present invention)
Prior to the description of the embodiments of the present invention, the features of the present invention will be first outlined. The present invention is characterized in that a fixture is attached to a stabilizer that prevents the electronic device from falling by screwing. Furthermore, the fixture is characterized in that it is structured to interfere with the shaft of a leveler (self-standing surface adjusting mechanism) fixed to the base frame of an electric device for self-supporting and to suppress deformation of the stabilizer. is there.

  In other words, if the stabilizer tries to cause deformation as the electronic device falls, the fixture fixed to the stabilizer functions to attract the leveler shaft on the bottom surface of the electronic device in the front direction. It has a structure that suppresses deflection and improves the fall prevention function of electronic devices. Furthermore, as a structure for tightening and loosening the screw from the front of the electronic device, it is characterized in that the stabilizer can be easily attached and detached.

  The mechanism for preventing the electronic device from falling down is further described as follows. For example, when the electronic device is pulled out in the front direction and the electronic device is inclined to the front direction and is about to fall down, the bottom portion of the L-shaped bent shape stabilizer composed of the bottom portion and the rising portion is It tries to prevent the electronic device from falling over by pressing the installation surface where the device is installed. However, when the weight of the electronic device is large, there is a high possibility that the deflection due to the load from the electronic device is generated in the portion fixed to the electronic device at the rising portion of the stabilizer.

  Here, according to the fall prevention mechanism of the present invention, the fixture fixed by screwing to the stabilizer is hooked on the shaft of the leveler provided at the bottom for self-supporting of the electronic device, thereby causing a load from the electronic device. Is applied to the stabilizer, the force that pulls the shaft of the leveler on the bottom of the electronic device in the front direction (in other words, the force that pulls the rising part of the stabilizer closer to the leveler) is generated. It is possible to suppress the electronic device from falling over in the front direction more reliably.

(Description of the configuration of this embodiment)
Next, the structure of the embodiment of the present invention will be described in detail with reference to FIGS. FIG. 1 is a conceptual diagram illustrating an example of an image in which a stabilizer and a fixture are attached as an electronic device overturn prevention mechanism according to the present invention, and FIG. 2 is an example of features of the electronic device overturn prevention mechanism according to the present invention. FIG. 3 is a side view showing an example of a feature of the electronic device overturn prevention mechanism according to the present invention, and shows a side view of the partial enlarged portion of FIG.

  In FIG. 1, the electronic device 1 includes a leveler 4 on the bottom surface that enables self-standing installation as a self-standing surface adjustment mechanism. In the L-shaped bent stabilizer 2 having a bottom surface portion 2a and a rising portion 2b, the rising portion 2b is attached to the front surface (front surface) of the electronic device 1 by screwing to prevent the electronic device 1 from falling. On the other hand, as shown in FIGS. 2 and 3, the fixture 3 has an L-shaped bent shape having a ceiling portion 3a and a falling portion 3b, and the falling portion 3b is screwed to the electronic device 1. It is further screwed and fixed to the rising portion 2b of the fixed stabilizer 2. Further, the ceiling portion 3a of the fixture 3 is inserted and arranged in a state of being close to the bottom surface portion of the electronic device 1, and as shown in FIG. 2, a cutout portion 3c is formed in a part of the ceiling portion 3a. The cutout portion 3c is disposed in a state where the cutout portion 3c is fitted to the shaft of the leveler 4.

  That is, when the electronic device 1 is tilted, the rising portion 2b of the stabilizer 2 fixed to the electronic device 1 also tends to tilt. At this time, the standing of the fixture 3 fixed to the rising portion 2b of the stabilizer 2 is also attempted. The falling part 3b also tries to tilt together. However, since the ceiling portion 3a of the fixture 3 is hooked on the shaft of the leveler 4 by the notch portion 3c, the force that pulls the shaft of the leveler 4 on the bottom surface of the electronic device 1 in the front direction (in other words, the rising portion of the stabilizer 2). 2b), the electronic device 1 can be prevented from overturning without the stabilizer 2 being bent.

  The stabilizer 2 can be attached and detached by tightening and loosening the screw from the front of the electronic device 1, and the fixture 3 can be attached to the electronic device from the front (front) of the electronic device 1. 1 can be inserted into the bottom surface of the electronic device 1 and is fixed to the stabilizer 2 with screws from the front of the electronic device 1 so that it can be easily attached and detached, and the stabilizer 2 and the fixture 3 can be easily attached and detached. In addition, since it is not a matter of attachment / detachment time, the installation work of the electronic device 1 can be facilitated.

  Here, as shown in the partial detail view of FIG. 2, the stabilizer 2 includes a bottom surface portion 2 a serving as an installation surface with respect to the floor extending in front of the electronic device 1, and an L-shaped bent portion extending upward. And a rising portion 2b serving as a fixed surface to the electronic device 1. Furthermore, the falling part 3b of the fixture 3 is fixed to the rising part 2b of the stabilizer 2 with a screw. The fixture 3 has a ceiling portion 3a having a notch portion 3c formed in the ceiling portion 3a and extending right and left to the rear of the shaft of the leveler 4 provided for the electronic device 1 to be self-supporting. . That is, the shaft of the leveler 4 is fitted in the notch 3c of the ceiling 3a of the fixture 3.

(Description of operation of this embodiment)
Next, the operation of the overturn prevention mechanism of the electronic device in FIG. 1 will be further described with reference to FIG. In FIG. 1, the falling portion 3 b of the fixture 3 is further screwed and fixed to the rising portion 2 b of the stabilizer 2 fixed to the electronic device 1 with a screw as described above.

  When the electronic device 1 is tilted, as shown in the side view of FIG. 3, the bottom surface portion 2 a of the stabilizer 2 stretches the floor (installation surface), thereby starting the overturning preventing operation of the electronic device 1. At this time, a force attracted forward (to the left side in FIG. 3) is also generated in the fixture 3 fixed to the rising portion 2 b of the stabilizer 2 due to deflection (displacement) of the rising portion 2 b of the stabilizer 2. However, the ceiling 3a of the fixture 3 cannot be displaced forward (to the left in FIG. 3) because the notch 3c is caught on the shaft of the leveler 4 provided in the electronic device 1. As a result, it is possible to suppress the deflection of the rising portion 2b of the stabilizer 2 and to easily prevent the electronic device 1 from falling over.

  Further, as shown in FIG. 3, the stabilizer 2 can be attached / detached by tightening or loosening a screw from the front surface (left side direction of FIG. 3) of the electronic device 1 and is inserted into the bottom surface portion of the electronic device 1. The fixture 3 arranged in such a manner is also inserted from the front of the electronic device 1 (the left side in FIG. 3) and interferes with the leveler 4, and can be attached to and detached from the stabilizer 2 by loosening the screws. In addition, the installation work of the electronic device 1 can be facilitated.

(Effect of this embodiment)
The first effect is that the cost can be reduced as a fall prevention mechanism of the electronic device 1. The reason is that it is possible to configure a fall prevention mechanism by adopting only two parts having a simple structure of the stabilizer 2 and the fixture 3.

  The second effect is an improvement in maintainability. The reason is that the stabilizer 2 according to the present embodiment can be attached and detached from the front of the electronic device 1, and as a result, when the electronic device 1 is installed, the stabilizer 2 is attached in advance. This is because there is no need to suffer from time constraints.

  The third effect is that the stabilizer 2 and the fixture 3 can be easily attached and detached by tightening and loosening the screw from the front of the electronic device 1, so that the number of work steps can be reduced even when the electronic device 1 is moved. be able to.
