Description

  The present invention relates to a component holding structure in which a rotating component is rotatably held on a holder side and rotated to a fixed position by biasing a torsion spring.

  6 is an external perspective view of a monitor device of the type installed on the ceiling, and FIG. 7 is a longitudinal sectional view. In this monitor device, the monitor 1 is held by a lock part 3 interlocked with the button 2 and is housed in a holder 4. When the button 2 is pressed, the button 2 pushes up the operation portion 3a of the lock component 3, so that the lock claw 3c is released from the lock hole 1a of the monitor 1 by rotating around the shaft portion 3b. When the latching of the lock part 3 and the monitor 1 is released in this way, the monitor 1 rotates about the shaft 5 and the monitor screen 6 is opened to allow viewing.

FIG. 8 is a perspective view showing a holding structure of the lock component (rotary component) 3 provided inside the holder 4. A winding portion 7a of the torsion spring 7 is externally mounted on the shaft portion 3b serving as a rotation shaft of the lock component 3, and one end portion 7b of the torsion spring 7 presses the holder 4, and the other end portion 7c is a lock component. By pressing 3 and applying a load to both, the lock part 3 is urged by the torsion spring 7 and rotates in a direction to push back the button 2.
The holder 4 is provided with bearings 4a and 4b that rotatably hold the shaft 3b of the lock component 3, and a spring latch 4c that latches one end 7b of the torsion spring 7. It has been.

  FIG. 9 is a diagram illustrating the procedure for assembling the lock component 3. When the lock component 3 and the torsion spring 7 are assembled to the holder 4 side, first, the winding portion 7a of the torsion spring 7 is externally mounted on the shaft portion 3b of the lock component 3, and one end side of the shaft portion 3b is supported by the bearing portion 4a. Insert diagonally into the hole. At this time, the end 7 b of the torsion spring 7 is hooked on the spring hooking portion 4 c of the holder 4. Subsequently, the other end side of the shaft portion 3b is inserted into the hole of the bearing portion 4b and assembled, and the end portion 7c of the torsion spring 7 is hooked and fixed to the operation portion 3a while applying a load for rewinding. Due to the rewinding load applied to the torsion spring 7, the lock component 3 rotates in the direction in which the button 2 is pushed back.

  In this holding structure, since the lock parts 3 are obliquely assembled to the holder 4 one by one, the work is difficult and takes time, and a work space is also required. Furthermore, since the assembling work is performed with a load applied to the torsion spring 7, in addition to the load on the operator, a load is also applied to the shaft portion 3b of the lock part 3, and in the worst case, the shaft portion 3b. However, there was also a problem that it was damaged by the load.

  Therefore, in Patent Document 1, for example, a tilt shaft provided on both sides of a tilting body (rotating part) is rotatably connected to a unit base so that the tilt base can be tilted. Two U-grooves to be connected are provided, and a protrusion for preventing the tilt shaft from coming off is provided at the opening of each U-groove. When assembling, the tilting shaft of the tilting body is inserted from the opening of the U-groove and connected to the retaining projection in a locked state. Therefore, unlike the holding structure shown in FIGS. 8 and 9, it is not necessary to assemble the shafts one by one at an angle, and the assembly is easy.

As described above, in the conventional holding structure as shown in FIG. 8 and FIG. 9, the bearing portion of the holder is held so as to surround the shaft portion of the rotating part. On the other hand, the work of assembling the rotating parts to the holder was not easy. On the other hand, the holding structure according to Patent Document 1 can be easily assembled by pushing the tilting shaft into the U groove of the unit base. However, the U-groove has a shape in which the upper side is opened and has a structure that partially holds the tilting shaft.
Moreover, in the case of a structure that is assembled while applying a rewinding load to the torsion spring, there is a problem that the rotating parts are easily damaged.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a component holding structure that allows easy assembly of components and holds them securely.

  In the component holding structure of the present invention, the rotating component has a shape protruding from the shaft portion and has a first spring latching portion that latches one end of the torsion spring, and the holder is in a position shifted from each other. A pair of holding parts that protrude and protrude in a staggered manner inward and hold the shafts pushed in from the front end side alternately from both sides in a direction orthogonal to the axial direction, and torsion springs. A second spring latching portion for latching the other end of the shaft, holding the shaft portion of the rotating component rotatably on the holder side, and fixing the rotating component by urging the torsion spring provided on the shaft portion. Rotate to position.

  According to the present invention, the shaft portion of the rotating part is pushed into the pair of holding portions that protrude in positions shifted from each other and the tips are alternately bent inward, and the shaft portions are alternately hooked from both sides to be held rotatably. As a result, the rotating parts can be easily assembled and securely held.

Hereinafter, in order to explain the present invention in more detail, modes for carrying out the present invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
The component holding structure according to the first embodiment will be described using an example applied to the holding structure of the lock component (rotating component) 3 in the monitor device shown in FIGS. 6 and 7 described above. 6 and 7 are incorporated. However, the rotating component to be held by the component holding structure may be other than the lock component 3 and can be applied to the holding structure such as the button 2. Further, the component holding structure may be applied to an article other than the monitor device.

FIG. 1 shows a component holding structure according to the first embodiment. FIG. 2 shows the structure of the lock component 3 and FIG. 3 shows the structure of the holder 4.
The lock part 3 has an operation part 31, a shaft part 32, and a lock claw 33, similarly to the conventional structure described above. When the operation unit 31 is pushed up to the button 2 from the position (fixed position) shown in FIG. The shaft portion 32 rotates around the axial direction X (shown in FIG. 2) according to the movement of the operation portion 31. The lock claw 33 rotates according to the movement of the operation unit 31 and is caught or removed from the lock hole 1a (shown in FIG. 7) of the monitor 1. When the lock claw 33 is caught in the lock hole 1 a of the monitor 1, the monitor 1 is held in the holder 4. When the lock claw 33 is detached from the lock hole 1 a, the monitor 1 is rotated around the shaft 5. The monitor screen 6 can be opened to a viewable position.

  The lock component 3 has a shape protruding from the shaft portion 32 and has a spring hooking portion (first spring hooking portion) 34 that hooks one end 72 of the torsion spring 7. Further, the lock component 3 has a shape protruding from the shaft portion 32 in a direction different from that of the spring hook portion 34, and temporarily holds the other end portion 73 of the torsion spring 7. Have In the illustrated example, the end 73 of the torsion spring 7 is bent into an L shape so that it can be easily hooked on the spring temporary hook 35. However, the present invention is not limited to this, and the spring temporary hook is not limited thereto. 35 may be bent in an L shape, and the end 73 may be kept in a linear shape like the other end 72.

  The holder 4 includes two pairs of holding portions 41 and 42 that rotatably hold the shaft portion 32 of the lock component 3, bearing portions 43 that support the shaft portion 32 (three locations in the illustrated example), and a torsion spring. 7, a spring latching portion (second spring latching portion) 44 that latches the end portion 73, and a shape protruding to a position adjacent to the spring latching portion 44. The temporary latch release part 45 which removes the edge part 73 of the torsion spring 7 latched automatically and guides to the spring latch part 44 is provided. The temporary latch release portion 45 is provided with a guide surface 45 a that is inclined toward the adjacent spring latch portion 44.

FIG. 4 is a cross-sectional view of the component holding structure according to the first embodiment cut along the line AA shown in FIG.
As shown in FIGS. 1, 3, and 4, the pair of holding portions 41 and 42 includes hooking portions 41 a and 42 a that protrude at positions shifted from each other and whose tips are alternately bent inward. The hook portions 41a and 42a are alternately hooked on both sides of the shaft portion 32 in the direction orthogonal to the axial direction X and are rotatably held. The pair of holding portions 41 and 42 are provided at both end portions of the shaft portion 32 in the axial direction X, respectively.
As shown in FIG. 4, the length d of the hook portion 41 a is made longer than the radius r of the shaft portion 32, and the length d of the hook portion 42 a is also made longer than the radius r of the shaft portion 32. Thereby, in hook part 41a, 42a, the part hooked alternately to axial part 32 overlaps, and it can prevent removal of axial part 32 more certainly.

Next, the assembly procedure will be described with reference to FIG.
As shown in FIG. 5, in the component holding structure of the first embodiment, the lock component 3 can be assembled simply by lowering it from above the holder 4. First, the winding portion 71 of the torsion spring 7 is externally mounted on the shaft portion 32 of the lock part 3, and the end portion 73 is hooked on the spring temporary hooking portion 35. Subsequently, the other end 72 is hooked to the spring hook 34 while applying a rewinding load. Thereby, first, the torsion spring 7 is temporarily fixed to the lock part 3.

  Subsequently, the shaft portion 32 that covers the winding portion 71 is pushed between the pair of holding portions 41 and 42 from the side of the hook portions 41a and 42a. Thereby, the hook portions 41a and 42a are bent and spread, and the shaft portion 32 can be inserted. Then, when the shaft portion 32 comes into contact with each of the bearing portions 43, the hook portions 41a and 42a return to their original shapes, and the upper side of the shaft portion 32 is pressed to prevent it from coming off. As a result, as shown in FIG. 4, the upper side of the shaft portion 32 comes into contact with the hook portions 41 a and 42 a and the lower side comes into contact with the bearing portion 43, and the lock component 3 is held rotatably on the holder 4 side. Is done.

  Further, when the shaft portion 32 is pushed into the holding portions 41, 42, the temporary latch release portion 45 protruding from the holder 4 is temporarily latched on the spring temporary latch portion 35 of the lock component 3. 7 is brought into contact with the end portion 73 and the torsion spring 7 is slid along the guide surface 45a to release the end portion 73 from being latched. The end 73 of the torsion spring 7 released from the temporary latch comes into contact with the adjacent spring latch 44 and is loaded.

  When the button 2 of the monitor device is pressed in this state, the button 2 pushes up the operating portion 31 from the fixed position against the biasing force of the torsion spring 7 and rotates the lock component 3. When the force to push the button 2 is lost, the torsion spring 7 urges the spring hooking portion 34 (the operation portion 31) toward the home position by the rewinding load, and pushes the button 2 back to the original position.

  In addition, when removing the lock | rock component 3, what is necessary is just to lift the axial part 32 up, bending so that the holding parts 41 and 42 may be expanded. Thereby, it can remove easily.

  As described above, in the component holding structure according to the first embodiment, the lock component 3 has the shape protruding from the shaft portion 32 and has the spring latching portion 34 that latches one end 72 of the torsion spring 7. The holder 4 is provided with hook portions 41a and 42a that protrude at positions shifted from each other and the tips are alternately bent inward, and the shaft portions 32 pushed in from the tip side are staggered from both sides in the direction orthogonal to the axial direction X. A pair of holding portions 41 and 42 that are hooked and rotatably held and a spring hooking portion 44 that hooks the other end 73 of the torsion spring 7 are provided. For this reason, the shaft part 32 of the lock part 3 can be easily assembled by pushing between the pair of holding parts 41 and 42, and the work space can be reduced. Further, the lock part 3 can be reliably held by the hook portions 41a and 42a.

  According to the first embodiment, the lock component 3 has a shape protruding from the shaft portion 32 in a direction different from the spring hooking portion 34, and the end 73 of the torsion spring 7 is connected to the lock component 3 as a holder. 4 is configured to have a temporary spring latching portion 35 that is temporarily latched before assembling to 4, and the other holder 4 has a shape protruding at a position adjacent to the spring latching portion 44, and the shaft portion of the lock part 3 When 32 is pushed between the pair of holding portions 41, 42, the end portion 73 of the torsion spring 7 temporarily latched on the spring temporary latching portion 35 of the lock part 3 is removed, and the spring latching portion 44. It has the structure which has the temporary latch release | release part 45 which guides to. For this reason, it is not necessary to apply a rewinding load to the torsion spring 7 when the lock part 3 is assembled, and damage to the lock part 3 can be suppressed.

  In the present invention, any constituent element of the embodiment can be modified or any constituent element of the embodiment can be omitted within the scope of the invention.

  As described above, the component holding structure according to the present invention can be assembled simply by pushing the shaft portion of the rotating component between the pair of holding portions, so that the lock, button, lever, etc. holding structure of the spring can be held.
