Description

  The present invention relates to a stand mechanism that can be folded into a cabinet body such as an electronic device and used when the electronic device is vertically placed on a floor surface, and an electronic device including the stand mechanism.

  In recent years, electronic devices corresponding to so-called digital home appliances such as hard disk recorders and DVD recorders are rapidly spreading in general households. Electronic appliances compatible with digital home appliances are becoming thinner and thinner year by year because of the need to secure product images and to store them in racks such as televisions.

  However, the functions of electronic devices compatible with digital home appliances are diversifying year by year, and there are many cases where a plurality of electronic devices exist in one home. In such a case, it may be difficult to store all electronic devices in a rack such as a television. In view of housing conditions in Japan, electronic devices are placed vertically on the side of a rack such as a television. There are also many cases to do.

  Conventionally, when an electronic device is placed vertically, a stand member, which is a separate housing that can be fitted into the cabinet of the electronic device, is used, and the cabinet is inverted by the stand member each time the electronic device is placed vertically.

In addition, for example, in Patent Document 1, a button unit that can be pushed into the cabinet by the weight of the electronic device is placed on the floor surface so that it is not necessary to separately prepare a stand member that is a separate housing. When the electronic device is installed on the floor surface and the button portion is pushed in by the weight of the electronic device, the electronic device having a mechanism for preventing a fall by protruding a plurality of legs out of the installation surface It is disclosed.

  When the button body 171 is pushed into the hole 172 by the user, or when pushed by the dead weight of the electronic device 2 placed vertically, the rotating part 12a is in contact with the inclined surface 174 of the button body 171. In an initial state before the main body 171 is pushed in, the distance L1 between the surface of the rotating part 12a and the push-in surface of the button main body 171 is such that the outer surface of the cabinet 21 of the electronic device 2, that is, the outer surface of the recess 13 and the button main body 171. It is necessary to be larger than the distance L2 from the end of the inclined surface 174. In this case, since the rotating portion 12a contacts the inclined surface 174 of the button main body 171, the button main body 171 can be further pushed into the hole 172 by further rotating the rotating portion 12a.

  FIG. 5 is a cross-sectional view of the vicinity of the lock button 17 in a plane perpendicular to the central axis of the lock button 17 in a state where the rotary body 12a is rotated and the button body 171 is completely pushed into the hole 172. As shown in FIG. 5, by further rotating the rotating part 12 a, the button body 171 is further pushed into the hole 172, so that the rotating part 12 a can pass through the lock button 17.

  In the above description, the case where the inclined surface 174 of the button main body 171 is formed in one direction of the button main body 171 is described. However, the present invention is not limited to this. Two inclined surfaces may be formed which are inclined so that the protruding portion of the button member 171 becomes shorter in the direction of the position of the rotating portion 12a in the state of being housed in the direction and in the opposite direction.

  As described above, according to the first embodiment, the plurality of support portions 11 and 11 can be projected out of the stationary surface or accommodated in the cabinet 21 according to the rotation of the rotation portions 12a and 12b. The support portions 11 and 11 that reliably support the cabinet 21 can be reliably projected without being influenced by the situation of the floor surface on which the cabinet is placed, and even if the cabinet 21 is placed vertically, it is possible to easily prevent overturning. It is possible to prevent an internal device from being damaged by a fall and to provide an electronic device that operates normally.

  In addition, when the plurality of support portions 11 and 11 are accommodated in the cabinet 21 by the lock button 17 that can be pushed in, the rotation of the rotation portions 12a and 12b is locked and cannot be moved, so that the user can move with the finger. Only when the lock button 17 is pushed in, or when the cabinet 21 is vertically placed on the floor and the lock button 17 is pushed in by the weight of the cabinet 21, the rotation of the rotary portions 12a and 12b is unlocked and can be rotated. The support part 11 for preventing overturning can protrude from the cabinet 21.

  Further, in a state where the plurality of support portions 11 and 11 protrude out of the installation surface of the cabinet 21, even when the cabinet 21 is vertically placed on the floor surface and the lock button 17 is pushed in by the weight of the cabinet 21. The rotating parts 12a and 12b are not completely stored in the cabinet 21 by mistake due to the rotation of the rotating parts 12a and 12b. Therefore, when the cabinet 21 is placed vertically, the plurality of support portions 11 and 11 can always be protruded out of the installation surface of the cabinet 21 and can be prevented from falling.

  On the other hand, when the cabinet 21 is moved, the rotation portions 12a and 12b are not unlocked unless the lock button 17 is pushed with a finger or the like, and the plurality of support portions 11 and 11 are inadvertently detached from the cabinet 21. The electronic device 2 can be safely moved without protruding.

The second embodiment is characterized by further including a drive device that imparts rotation to the rotating portions 12a and 12b of the stand mechanism 1 according to the first embodiment. Hereinafter, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 6 is a cross-sectional view of the vicinity of the lock button 17 on a plane perpendicular to the central axis of the lock button 17 in the stand mechanism 1 according to Embodiment 2 of the present invention. As shown in FIG. 6, a push switch 31 that can be pushed down by the button body 171 is provided inside a coil spring 173 that is a biasing member that biases a reaction force against the button body 171.

  When pushed on the bottom surface of the button body 171, the push switch 31 sends a drive signal to an ECU (electronic control unit) 33 that controls the motor 32 that drives the rotating parts 12 a and 12 b. The ECU 33 that has received the drive signal from the push switch 31 rotates the motor 32 at an appropriate rotation speed and rotation direction. According to the rotation of the motor 32, the rotating portions 12 a and 12 b can be rotated in the direction in which the support portions 11 and 11 protrude from the cabinet 21.

  Similar to the first embodiment, a predetermined inclined surface 174 is formed in the portion into which the button main body 171 is pressed in the direction in which the rotating portion 12a comes into contact. The inclined surface 174 is inclined so that the protruding portion of the button member 171 becomes shorter toward the position of the rotating portion 12a in a state where the rotating portion 12a is housed in the recess 13 of the cabinet.

  When the rotating part 12 a rotates from the state accommodated in the recess 13 of the cabinet 21 and the support parts 11 and 11 are to protrude from the cabinet 21, the rotating part 12 a first contacts the outer peripheral surface of the button body 171. As shown in FIG. 6, when the rotating part 12a is rotating, the push switch 31 is pushed in on the bottom surface of the button main body 171. That is, the button main body 171 is pushed in with a finger, or as a stationary surface. Since the button main body 171 is pushed in by the weight of the electronic device 2 by placing, the rotating portion 12a contacts the inclined surface 174 of the button main body 171. Therefore, the button main body 171 is pushed down to the hole 172 along the inclined surface 174 of the button main body 171 by the rotation of the rotating portion 12a.

  FIG. 7 shows a plane perpendicular to the central axis of the lock button 17 in a state where the rotary unit 12a passes through the hole 172 after the button body 171 is completely pushed into the hole 172 by rotating the rotary unit 12a. It is sectional drawing of the lock button 17 vicinity. As shown in FIG. 7, by further rotating the rotating part 12 a, the button body 171 is further pushed into the hole 172, so that the rotating part 12 a can pass through the lock button 17.

  In the above description, the case where the inclined surface 174 of the button main body 171 is formed in one direction of the button main body 171 is described. However, the present invention is not limited to this. Two inclined surfaces may be formed which are inclined so that the protruding portion of the button member 171 becomes shorter in the direction of the position of the rotating portion 12a in the state of being housed in the direction and in the opposite direction.

  As described above, according to the second embodiment, even when the rotating parts 12a and 12b are rotated by a driving device such as a motor, the plurality of supporting parts 11 and 11 protrude out of the stationary surface, or the cabinet 21. Therefore, the support portions 11 and 11 that support the cabinet 21 can be reliably projected without being affected by the situation of the floor surface on which the cabinet 21 is installed, and the cabinet 21 is placed vertically. However, it is possible to easily prevent the overturn, prevent the internal device from being damaged by the overturn, and provide an electronic device that operates normally.

  When the cabinet 21 is placed vertically on the floor surface, the lock button 17 is pushed into the cabinet 21 due to the weight of the electronic device 2 and the rotating portion 21a can be rotated by driving the motor. When placed, the support portions 11 and 11 for preventing the fall can be automatically protruded from the casing, and the fall can be prevented in advance.

  The power supply to the motor 32 that drives the rotating unit 12a may be interlocked with the main power switch of the electronic device 2. In this case, when the main power switch of the electronic device 2 is turned on, the motor 32 that drives the rotating units 12a and 12b is configured to operate. In the on state, when the main power source is turned on, the rotating parts 12 a and 12 b rotate and the plurality of support parts 11 and 11 protrude from the cabinet 21. Therefore, for example, even when a disk or the like that is easily damaged by an impact during operation is incorporated, the plurality of support portions 11 and 11 for preventing overturning reliably protrude from the cabinet 21 when the disk or the like is operated. It is possible to prevent damage to internal devices such as a disk due to a fall.
