Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a handle attachment device in which the handle is rotatably attached to a main body via a hinge mechanism, and particularly relates to a handle attachment device suitable for use in a porta-pull type radio-equipped cassette tape recorder. Summary of the Invention 1 The present invention provides a mechanism for attaching a rotary handle, and by grasping the handle and lifting the main body, the rotation stopper of the handle automatically moves to prevent rotation between the handle and the main body. Moreover, it concerns a handle that releases its rotation stop when the main body is placed and can be easily stored in the storage position, and a hinge mechanism that is offset from the vertical line passing through the center of gravity. Even if a handle is attached to the handle, the main body will not tilt when lifted.

[Conventional technology λ For example, in a portable type cassette tape recorder with a radio, a handle for carrying the tape recorder is attached to the cabinet, and the handle can be used to carry the tape recorder as needed. The handle is usually rotatably attached via a hinge mechanism, so that when carrying the item, the handle is raised, and when not in use, the handle is rotated and stored in the recess of the cabinet. The hinge is mounted near a vertical line passing through the center of gravity, thereby preventing the tape recorder from tilting when the tape recorder is lifted by the handle. Problems that the K invention attempts to solve]

If the hinge mechanism is placed on a vertical line passing through the center of gravity to prevent the tape recorder from tilting when lifted, the hinge mechanism will restrict the placement of structures and parts within the cabinet, making it difficult to design the tape recorder. The degree of freedom is also reduced. Therefore, a structure has been proposed in which a hinge mechanism is offset to the rear of the cabinet and a stopper mechanism is installed to prevent the handle from rotating when the cabinet is lifted. However, in such a structure, in order to release the rotation stopper, a button must be pressed, making it inconvenient to use.Also, such a rotation stopper and its Providing a button for release has the drawbacks of complicating the structure and increasing cost.The present invention was made in view of these problems, and it The object of the present invention is to provide a device for attaching a handle that simply constitutes a rotation stopper mechanism and a release mechanism for preventing the main body from tilting by providing a hinge mechanism at a position offset from the main body. Means for Solving Problem K] The present invention provides a device in which a handle is rotatably attached to a main body via a hinge mechanism, wherein the hinge mechanism has a hinge pin and a pin hole, and An extension is formed in the pin hole, and means for preventing rotation of the handle relative to the body is provided, and when the hinge pin enters the extension of the pin hole, the blocking means prevents rotation of the handle. K effect] Therefore, when the handle is moved to the position where the main body is lifted,
Means is provided to ensure that the hinge pin enters the extension of the pin hole and to prevent this from happening. By preventing the handle from rotating, it is possible to prevent the main body from tilting when lifted, even if the hinge mechanism is provided at a position offset from a vertical line passing through the center of gravity of the main body. Further, since the rotation stopper is constituted by the extension of the pin hole and the blocking means, the mechanism is simple and the number of parts is reduced. By roughly moving the hinge pin from this extension to the larger pin side, it is possible to release the rotation stopper, eliminating the need for a mechanism such as a button to release the rotation stopper, and easily stopping the rotation with one hand. It becomes possible to release the handle and store it in a predetermined storage position. (Embodiment) Fig. 1 and Fig. 2 show a handle device for a handle of a cassette tape recorder with a radio according to an embodiment of the present invention.
It is equipped with a handle 1 located almost in the center.
1 allows this tape recorder to be lifted and carried. The handle 11 of the tape recorder is inserted into the mouth-shaped recess 12 provided on the back side of the cabinet 10.
The handle 11 is housed in the recess, and the handle 11 is pulled out from this recess and rotated when lifting the knife. The handle 11 is rotatably supported by a hinge pin 14 provided on a pair of hinge brackets 13 mounted inside the cabinet 10. That is, the handle 11 is provided with a pin hole 15,
This pin hole 15 receives the hinge pin 14. The hinge pin 14 on the side of the cabinet 10 has a flat portion 18 on its lower end side, and is cut out on both sides. On the other hand, the pin hole 15 on the side of the handle 11 has a notch extending downward at its lower part, and the hinge pin 14 is introduced into this notch 19. Further, the handle 11 is provided with offset pins 20 that protrude inwardly so as to face each other. The offset pin 20 is offset downward with respect to the pin hole 15 and is pressed by a pressing spring 21. Both ends of the spring 21 are bent into an opening shape, and the bent portions 22 push the offset pin 20 from above. Further, the center portion of the pressing spring 21 is wound in a circular shape, and this portion is screwed to the boss 24 of the cabinet 10 with a screw 23. 10 more cabinets
A rib 25 is provided on the side, and the rib 25 presses one side of the pressing spring 21 downward. Next, the operation of the apparatus for attaching the handle constructed as above will be explained. Figures A-1 to A-4 do not show the take-out operation of the handle;
4 and the pin hole 15 are shown in 8-1 to B-4, respectively. Further, the relationship between the offset pin 20 and the pressing spring 21 at this time is shown corresponding to C-1 to C-4. When the IR handle 1 is housed in the recess 12 of the cabinets 1 to 10 as shown in FIG. 1 A-1, C-
As shown in FIG. 1, the bent portion 22 of the spring 21 presses against the flat surface 26 of the off-stop pin 20 of the handle 1, thereby suppressing the wobbling of the stored handle 11. In such a state, the handle 11 as shown in A-2
When the handle 11 is lifted, the handle 11 is rotated around the hinge pin 14 as shown in B-2. , handle 1
1 is rotated to the position where it ends at A-3, the offset pin 20 becomes like C-3. Since this offset pin 20 is offset downward with respect to the pin hole 15 as described above, it is located at the lowest position at this position, and the amount of deformation of the spring 21 that is in contact with this pin 20 is becomes minimum. However, since this spring 21 still pushes the handle 11 downward, the handle 11 is stably held in this state. At this time, as shown in B-3, since the flat portion 18 of the hinge pin 14 and one notch of the pin hole 15 are aligned, the handle 11 is in a state where it can move upward. In such a state, if the tape recorder is lifted by the handle 11, the weight of the tape recorder will exceed the elastic restoring force of the pressure spring 21, and the handle 11 will be lifted.
moves upward. That is, the hinge pin 14 enters into the notch 19 of the pin hole 15. Therefore, the handle 11
cannot rotate around the hinge pin 14. Therefore, the hinge mechanism including the hinge pin 14 is attached to the cabinet 10.
Even if the tape recorder is placed at a rear position offset from the center of gravity of the tape recorder, the tape recorder will not tilt when lifted by the handle 11. When the lifted tape recorder is put down, the handle 11 is pushed downward via the offset pin 20 by the elastic restoring saw of the pressing spring 21, so that it returns to the state of B-3 and the rotation of the handle 11 is prevented. becomes free. When storing the handle 11, the operation to take out the handle 11 described above may be reversed, and the handle 11 is rotated about the hinge pin 14 and stored in the four parts 12. At this time, the relationship between the offset pin 20 and the pressing spring 21 changes in the order of C-3, C-2, and C-1. Since the offset pin 20 is attached to the handle 11 with a downward offset, when the offset pin 20 is rotated in the opposite direction, the pressure spring 2
1 is deformed so as to be pushed upward, and a resistance force is generated against the handle 11 falling under its own weight. Therefore, the handle 11 is prevented from strongly hitting the back surface of the cabinet 10 and making noise, and smooth storage operation is achieved. Furthermore, in the retracted state, the bend 6ifE22 of the pressing spring 21 presses the flat surface 26 of the offset lower pin 20, making it possible to hold the handle 11 in the recess 12 in a click-like manner. According to the structure, the handle 11 is installed in such a way that a rotation stopper is constructed by devising the shapes of the hinge pin 14 and the pin hole 15, so a button or the like is required to release the rotation stopper. operation is no longer necessary. In addition, in order to activate the rotation stopper, it is only necessary to rotate the handle 11 upward and then lift the tape recorder using the handle 11, and the rotation stop is performed only by the tape recorder's own weight. sex will be improved. Moreover, such a rotation stopper structure has a simple mechanism and a reduced number of parts, resulting in a large cost advantage. K Application Example Σ Although the present invention has been described above with reference to the illustrated embodiment, the present invention is not limited to the above embodiment, and various modifications can be made based on the technical idea of the present invention. For example, in the above embodiment, the hinge pin 14 is provided on the cabinet 10 side.
is provided, and the pin hole 15 is formed on the handle 11 side, but these relationships may be reversed. Further, although the pressing force by the pressing spring 21 is applied downward, it may also be applied upward. Alternatively, it is also possible to omit the pressure spring 21.

【Effect of the invention】

As described above, in the present invention, the hinge mechanism of the handle has a hinge pin and a pin hole, the pin hole is formed with an extension, and furthermore, means for preventing rotation of the handle with respect to the main body is provided, and the hinge mechanism has a hinge pin and a pin hole. Rotation of the handle is prevented by blocking means upon entering the extension of the hole. Therefore, the simple M4 construction makes it possible to prevent the handle from rotating, and even if the hinge mechanism is placed at a position offset from the vertical line passing through the center of gravity, the two bodies will not tilt.
