Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device, and more particularly to a handle for an electronic device attached to a portable electronic device. 2. Description of the Related Art In portable electronic equipment, for example, a wireless amplification unit for a portable telephone, there is a case where it is used while being moved, or it is mounted on a dedicated rack and used as a fixed amplification device. There are cases. [0003] For this reason, a handle is provided in the mobile phone wireless amplifying unit to facilitate the holding of the mobile phone wireless amplifying unit during transportation or the work at the time of rack mounting. Further, when the handle is not transported or when the rack mounting operation is completed, the handle is folded so as not to be in the way. FIG. 5 shows a conventional handle for a portable electronic device.
This will be described with reference to FIG. [0005] In the figure, reference numeral 1 denotes a portable electronic device, and two sets of foldable handles 3 are provided on the front surface of a housing 2 of the portable electronic device 1. A pair of box-shaped shaft support members 4 are provided at upper and lower portions of the front surface of the housing 2 at vertically symmetric positions. The shaft support 4 has a hollow box-shaped front face and an open face. Both ends of a U-shaped handle 5 are inserted into the hollow portion of the shaft support 4 and are pivotally connected to the shaft support 4 via a shaft 6, and the handle 5 is moved outward from an upright state. The shaft support 4 functions as a stopper so that it cannot rotate, and can rotate from the upright state to the inside in contact with the front surface of the housing 2 or at least until it is parallel to the front surface of the housing 2. Further, as shown in FIG.
Is equipped with a lock mechanism for maintaining an upright state. The tip of the handle 5 has a semi-cylindrical surface so as to be rotatable.
The notch 7a and the notch 7b are different from each other by 90 ° with respect to the shaft 6. At the corner of the hollow portion of the shaft support 4, a sphere storage portion 8 is bored, and a sphere 9 is fitted into the sphere storage portion 8 so as to freely enter and exit. A compression spring 11 is fitted and urges the sphere 9 in a protruding direction. The sphere 9 fits into the notch 7a when the handle 5 is folded, and fits into the notch 7b when the handle 5 is upright. Due to the repulsive force of the spring 11, the notch 7
a, a fitting force between the notch portion 7b and the spherical body 9 is given. In the above configuration, for example, in order to erect the handle 5 from the state shown in FIG. 6, a force greater than the fitting force is applied to the handle 5 in a clockwise direction so that the spherical body 9 The sphere 9 is fitted on the notch portion 7b to generate a fitting force again, and the force on the handle 5 is removed. Is held upright. The above operation is the reverse of the above operation when folding. In the above-described handle for electronic equipment, when a force greater than the fitting force acts on the handle 5, the sphere 9 is disengaged from the notch portion 7 and rotates. Therefore, there is a problem that the handle 5 may rotate at an unexpected time, and may become unstable when the portable electronic device 1 is being carried. In view of such circumstances, the present invention suppresses the rotation of the handle unless the lock mechanism is firmly locked and the lock is released, so that the portable electronic device can be stably transported and mounted. Things. According to the present invention, a handle is rotatably provided via a shaft to a shaft support fitting attached to a housing, and a notch is provided at at least one place at a support end of the handle. A lock pin that is parallel to the shaft and engages with the notch portion is rotatably provided on the shaft support bracket. A cutout portion is formed in the lock pin, and the lock pin is rotated by rotation of the lock pin. The present invention relates to a handle for an electronic device configured to disengage a pin and a notch. Embodiments of the present invention will be described below with reference to the drawings. 1 to 3, the same components as those shown in FIGS. 5 and 6 are denoted by the same reference numerals. In the figure, two sets of foldable handles 3 are provided on the front surface of a housing 2 of the portable electronic device 1 (FIG. 5).
reference). A U-shaped handle 5 is rotatably provided via a shaft 6 on a shaft support 4 fixed to the front surface of the housing 2 (see FIG. 5). The tip of the handle 5 has a semi-cylindrical surface, and a notch 7a and a notch 7b are formed in the semi-cylindrical surface. The notch 7a and the notch 7b are also formed with a semi-cylindrical surface. I have. A shaft hole 14 having an axis parallel to the housing 2 is formed in a corner of the hollow portion of the shaft support 4. The shaft hole 1
A screw (not shown) is engraved at the base end of the fourth. A lock pin 15 is rotatably fitted in the shaft hole 14. The lock pin 15 has a notch 16 at the center.
Is formed, a screw 18 is engraved on one end, and a fitting portion 17 is provided on the other end. At least one end face of the lock pin 15 is provided with a slit 19 to which a tool tip such as a driver can be engaged. When the lock pin 15 is fitted into the shaft hole 14, the fitting portion 17 is rotatably fitted to the tip of the shaft hole 14, and is further locked by a driver or the like via the slit portion 19. By rotating the pin 15, the screw 1
8 can be screwed into a screw portion (not shown) of the shaft hole 14. Thus, the lock pin 15 is
The lock pin 15 is rotatable by being rotatably fitted with the screw 4 and screwed with the screw 18 so as not to be pulled out. If the shaft hole 14 is a blind hole and a compression spring is inserted between the tip of the fitting portion 17 and the bottom surface of the blind hole, the fitting portion 17 is prevented from loosening, and the lock pin 15 is locked. It is prevented from falling loose naturally. The operation of this embodiment will be described with reference to FIGS. FIG. 2 shows the handle 5 in a locked state, in which the handle 5 is folded, and the lock pin 15 is fitted in the notch 7a. In the locked state, the notch 16 of the lock pin 15 is located at a position disengaged from the notch 7a. To release the locked state, a driver or the like is inserted into the slot 19, and the lock pin 15 is removed. Rotate 180 °. When the notch 16 is in a state of facing the semi-cylindrical surface of the handle 5 (see FIG. 3), the lock pin 15 comes off the notch 7a, and the handle 5 can rotate freely. When the handle 5 is rotated by 90 °, the handle 5 is in an upright state, and the notch 7b is in a position facing the lock pin 15. When the lock pin 15 is rotated by 180 °, the lock pin 15 is fitted into the notch 7b, and mechanically restricts the rotation of the handle 5. Since the handle 5 is mechanically restrained by the lock pin 15, it does not rotate even if a large force is applied to the handle 5, and the handle 5 is held when the electronic device is transported or mounted on a rack. Unexpected rotation is prevented, and stable work is possible. When the handle 5 is locked by the lock pin 15 in locking and unlocking by the lock pin 15, the notch 16 is disengaged from the notches 7a and 7b, Since it is sufficient that the cylindrical surface 15 engages with the notch portions 7a and 7b, the lock pin 15 does not necessarily need to be rotated by 180 ° from the unlocked state, and may be, for example, 90 °. Since the notch 7a and the notch 7b need only be mechanically engaged with the lock pin 15, they may have a V-notch shape. Further, the shape of the notch 16 is such that the lock pin 15 is formed by the notch 7a and the notch 7b.
Therefore, the notch 16 may be formed by a cylindrical surface having a radius equivalent to the semi-cylindrical surface of the handle 5. The notch 7a and the notch 7b may be provided in three or more places. By providing three or more locations, for example, the handle 5 can be locked at a predetermined angle, for example, at a position of 45 °. If only the upright state of the handle 5 needs to be maintained, only one position may be used. Also, a point, an arrow, etc. is stamped on the exposed end face of the lock pin 15, and a dot, arrow, etc. is also stamped on the shaft support 4 so that the lock pin 15 is at the lock position. Alternatively, it may be determined whether the user is at the unlock position. Further, the lock pin 15 may be formed by forming a notch 16 in a bolt. Further, the lock pin 15 may be a simple pin having no screw portion. In this case, a retaining ring or the like for preventing withdrawal is provided. Further, the shape of the end of the handle 5 does not need to be a semi-cylindrical surface, but may be a polygonal surface that does not interfere with the shaft support 4. As described above, according to the present invention, a handle is rotatably provided via a shaft to a shaft support fitting attached to a housing, and at least one position is provided at a support end of the handle. A notch portion is formed on the shaft support bracket, and a lock pin that is parallel to the shaft and engages with the notch portion is rotatably provided. A cutout portion is formed in the lock pin, and the lock pin is rotated by rotation of the lock pin. Since the engagement between the lock pin and the notch portion is released, the handle is mechanically restrained in the locked state, and the handle does not rotate unless the lock is released. It has excellent effects such as stable operation.
