Description

  The present invention relates to an opening mechanism for opening, from a case, a bracket that has a magnet that is attracted by abutting against a case made of a magnetic member and can mount a heavy object.

  Conventionally, when installing a PC, when it is desired to make the depth as small as possible, the PC is installed sideways. In this case, since a power switch, an auxiliary storage device such as a CD, a USB port, and the like provided on the PC are on the side, it is necessary to move the PC to the front when accessing. On the other hand, since a weak device such as HDD is mounted inside the PC, it is desirable to fix it during normal times. Therefore, a bracket on which a PC can be mounted is provided, and the bracket is connected to a fixed side (case) via a hinge, and a structure that can be moved forward like a door is used. In normal times, the bracket is fixed to the case using screws, weak magnets and a cover.

  Here, in order to secure the fixing, it is necessary to perform screwing or to strengthen the magnet. However, in this case, when the bracket is opened, a screw is removed or a large force is required, which deteriorates usability. In addition, when a strong magnet is used, there is a possibility that an impact is applied to the PC by forcibly pulling the bracket.

  On the other hand, for example, a door opening / closing mechanism as disclosed in Patent Document 1 is known. In this door opening / closing mechanism, in order to open and close a door such as a control panel, a magnet on the main body side and a magnet on the door side are provided so as to be relatively movable. Then, the magnets are switched between the closing action position for holding the door in an attracted state by facing the different poles and the opening action position for making the door repulsive by facing the same poles. Switch. Thereby, a door can be easily opened and closed with respect to the main body side.

Japanese Patent Laid-Open No. 11-107608

  However, the door opening / closing mechanism disclosed in Patent Document 1 requires two magnets on the main body side and the door side, and has a problem of taking up space. Further, although the door can be fixed / released, there is a problem that a separate switching unit that can switch the position of the magnet on the main body side is necessary for the door opening / closing operation. Moreover, there exists a subject that a structure is complicated and an assembly cost and component cost are high.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide an opening mechanism that can easily open a bracket from a case with an inexpensive and simple configuration without taking up space. It is said.

FIG. 3 is a perspective view showing the configuration of the bracket 1 as seen from the bottom side. 1 and 3, the case 3 portion is omitted.
As shown in FIGS. 1 to 3, the bracket 1 is mounted with a heavy object such as a PC 2 and can be opened and closed from the case 3. The bracket 1 has a mounting portion 101 on which the PC 2 can be mounted. Further, the back side of the bracket 1 is attached to the case 3 via a hinge mechanism 102 and is configured to be openable and closable. A magnet 103 is provided on the bottom surface of the bracket 1 so as to be attracted by contacting the case 3 and fixing the bracket 1 to the case 3.

  The bracket 1 is provided with an opening mechanism 104 for releasing the fixation by the magnet 103 and opening the bracket 1 from the case 3. Hereinafter, the configuration of the opening mechanism 104 will be described with reference to FIGS. In the bracket 1 shown in FIG. 3, the back side is the case 3 side, and the near side is the open side.

  As shown in FIGS. 3 and 4, a rotating member 1041, which is a plate member provided from the case 3 side of the bracket 1 toward the open side, is provided on the bottom surface of the bracket 1. The rotating member 1041 has a fulcrum 1041a on the case 3 side, and is configured to be rotatable about the fulcrum 1041a. The rotating member 1041 is provided with a handle 1042 for rotating the rotating member 1041 on the open side. Further, the rotating member 1041 is provided with a claw portion 1043 that protrudes and retracts toward the case 3 side by rotating the rotating member 1041 on the case 3 side.

  Further, the bottom surface of the bracket 1 and the rotation member 1041 are provided with a cam mechanism 1044 (a cam groove 1045 and a pin 1046) that regulates the rotation amount of the rotation member 1041.

Next, the operation of the magnet release mechanism 104 configured as described above will be described with reference to FIGS.
In the state where the bracket 1 is fixed to the case 3, as shown in FIGS. 4 (a) and 5 (a), the rotating member 1041 is in a closed state. Therefore, the claw portion 1043 is in a state of being immersed in the bracket 1 side.

  On the other hand, when opening the bracket 1, when the user pulls the handle 1042 forward, the rotating member 1041 rotates in the opening direction around the fulcrum 1041a. Thereby, as shown in FIGS. 4B and 5B, the claw portion 1043 protrudes toward the case 3 and pushes the case 3. Then, by this pressing force, the adsorption between the magnet 103 and the case 3 is released, and the bracket 1 is opened from the case 3. At this time, the handle 1042 serves as a power point, the claw portion 1043 serves as an action point, and the claw portion 1043 operates based on this principle around the fulcrum 1041a. Therefore, even when a strong magnet 103 is used to fix a heavy object such as PC2, the bracket 103 can be easily released without being applied with a large force when pulling the handle 1042. Can be opened from case 3. When the bracket 1 is closed, the claw portion 1043 is brought into contact with the case 3 so as to be immersed in the bracket 1 and returned to the original position.

On the other hand, Embodiment 2 shows a configuration in which a leaf spring 1047 is sandwiched between the claw portion 1043 and the case 3.
FIG. 6 is a perspective view showing the configuration of the bracket 1 to which the opening mechanism 104 according to the second embodiment of the present invention is applied, as viewed from the bottom side, and FIG. is there. The release mechanism 104 according to the second embodiment shown in FIGS. 6 and 7 is obtained by adding a leaf spring 1047 to the release mechanism 104 according to the first embodiment. Other configurations are the same, and the description thereof is omitted.

  The leaf spring 1047 is provided on the bracket 1 and is disposed between the claw portion 1043 and the case 3. The tip of the leaf spring 1047 is bent toward the claw portion 1043 so as to surround the claw portion 1043 when the claw portion 1043 protrudes from the bracket 1. In this case, since the claw portion 1043 pushes the case 3 via the leaf spring 1047, the case 3 can be prevented from being scraped by the claw portion 1043. Further, when the claw portion 1043 presses the leaf spring 1047, a reaction force from the leaf spring 1047 is applied to the claw portion 1043. Therefore, the rotating member 1041 can be returned to the original position by this reaction force.

  As described above, according to the second embodiment, since the plate spring 1047 disposed between the claw portion 1043 and the case 3 is used, in addition to the effects of the first embodiment, further space saving is achieved. In addition, the case 3 can be prevented from being scraped by the claw portion 1043.

Embodiment 3 FIG.
