(Embodiment 1)
The first aspect of the present invention will be described with reference to the first embodiment.

  1 is a partial cross-sectional perspective view of the switchgear according to Embodiment 1, and FIG. 2 is an exploded perspective view thereof. In FIG. 1, reference numeral 11 denotes a substantially plate-like metal made of steel or copper alloy whose both ends are bent. The fixed body 12 is also a movable body, and a sliding material 13 such as Teflon (registered trademark) is attached to both ends of the movable body 12, and the movable body 12 is attached to the upper surface of the fixed body 11 via the sliding material 13. It is mounted so that it can move in the direction.

  Reference numeral 14 denotes a rocking body made of a plate material such as a steel plate or a copper alloy, which is substantially T-shaped, and is arranged between the fixed body 11 and the movable body 12, and a fulcrum hole 14 </ b> A at one end is penetrated by the rivet 15. A ring 16A is inserted into the through-hole 14B provided in the extended portion bent to the left from the locking portion at one end of the ring 12A by a rivet 15A from below. The end face on the other end side is formed in a flat portion 14C, and the left and right ends are formed in inclined portions 14D and 14E whose outer sides are lowered.

  Reference numeral 17 denotes a pressing body such as a steel plate or a copper alloy. The pressing body 17 is urged by a spring 18 in the direction of the oscillating body 14. Each ring 16C is rotatably locked.

  Here, the ring 16C is combined in the square hole 11C provided in the fixed body 11 shown in FIG. 2 and pressed so as to rotate and slide along the square hole 11C when the movable body 12 moves. The left and right ends of the body 17 are locked so as to be movable by a substantially L-shaped cut and raised portion 11A on the upper surface of the fixed body 11.

  The spring 18 is formed in a circular coil shape and is made of steel wire, copper alloy wire, or the like. The spring 18 is mounted in a slightly bent state between the pressing body 17 and the fixed body 11. The opening / closing device 20 is configured by being biased in the direction of the moving body 14, and the ring 16 </ b> B at the front end elastically contacting one inclined portion 14 </ b> D of the oscillating body 14.

  The opening / closing device 20 configured as described above has, for example, an operation unit 22A composed of a plurality of keys and a voice input unit 22B such as a microphone formed on the upper surface as shown in the perspective view of the mobile phone in FIG. The fixed body 11 is mounted on the fixed housing 22, and the movable body 12 is mounted on the movable housing 23 formed on the upper surface with a display unit 23 </ b> A such as a liquid crystal display element and a sound output unit 23 </ b> B such as a speaker. The movable housing 23 is held so as to be movable in the left-right direction with respect to the housing 22 to constitute an electronic device.

  In the above configuration, when the movable body 12 moves to the right with respect to the fixed body 11, as shown in the plan view of FIG. 3A, the ring 16B at the tip of the pressing body 17 biased by the spring 18 is used. However, when the movable body 12 is elastically contacted with the inclined portion 14D of the oscillating body 14 and is urged to the right, the lower left end of the flat portion 14C is movable by being elastically contacted with the protrusion 12B of the movable body 12. The body 12 is stationary while moving to the right.

  Therefore, the movable casing 23 to which the movable body 12 is attached is also stationary while moving to the right with respect to the fixed casing 22, and the operation section 22A and the voice input section 22B are exposed so that a call can be made. The body 23 is held in an open state.

  Further, when the movable casing 23 is slid to the left by hand from this open state, the movable body 12 is attached to the movable casing 23, so that the bottom surface of the movable body 12 is shown in FIG. Since the swinging body 14 locked to the left part moves to the left together with the movable body 12 while rotating to the right with the fulcrum hole 14A as a fulcrum, the height of the inclined portion 14D increases, and accordingly the ring 16B As a result, the spring 18 is further bent.

  As shown in FIG. 4A, the ring 16A locked to the left end of the rocking body 14 is held by the inner surface of the sliding contact portion 11B formed to protrude from the upper surface of the fixed body 11, and at the same time, the flat portion. The right lower end of 14C is elastically contacted with the protrusion 12C on the lower surface of the movable body 12, and the ring 16B at the tip of the pressing body 17 further deflects the spring on the inclined portion 14D.

  Thereafter, as shown in FIG. 4B, when the ring 16B moves to the flat portion 14C, the rocking body 14 is inclined to the right, so that the flat portion 14C has a downward inclination, and the ring 16B Rotate and slide rightward on the flat portion 14C.

  Here, the ring 16A at the left end of the oscillating body 14 is in elastic contact with the inner surface of the sliding contact portion 11B, and rotates and slides leftward on the inner surface of the sliding contact portion 11B. The oscillating body 14 is not tilted to the left by the pressing force of 16B.

  Further, from the position where the ring 16B exceeds the inclined portion 14D, the ring 16B biased by the spring 18 moves rightward on the flat portion 14C which has shifted to the moving direction as described above. Since it rotates and slides, as shown in FIG. 5A, the movable body 12 moves to the left at a stretch even when the hand is released.

  At this time, a force that tilts the oscillating body 14 in the right direction is generated by the pressing force of the ring 16B biased by the spring 18, but the lower right end of the flat portion 14C is in elastic contact with the protrusion 12C of the movable body 12. Therefore, the rocking body 14 does not further tilt to the right.

  Then, as shown in FIG. 5 (b), the ring 16B at the tip of the pressing body 17 comes into elastic contact with the other inclined portion 14E of the oscillating body 14, and the movable body 12 moves to the left and stops still. The body 23 is held in a state of being overlapped on the fixed housing 22, that is, in a closed state.

  On the contrary, when the movable body 12 is moved to the right from the above state, similarly, when the ring 16B is in a position where it is in elastic contact with the flat portion 14C from the inclined portion 14E of the oscillating body 14, the movable body 12 is spring-loaded. It is urged | biased by 18 and moves rightward at a stretch, and it will be in the open state shown to Fig.3 (a).

  When the movable body 12 moves to the right, as shown in FIGS. 6A and 6B, the lower left end of the flat portion 14C comes into elastic contact with the protrusion 12B of the movable body 12, The rocking body 14 tilts to the left, and the ring 16B rotates and slides leftward on the flat portion 14C. The ring 16A at the left end of the rocking body 14 elastically contacts the outer surface of the sliding contact portion 11B, and the outer surface of the sliding contact portion 11B. Is rotated to the right to open and close.

  At this time, after the movable body 12 is slightly moved from the right or left stationary position, the ring 16B at the tip of the pressing body 17 is elastically moved from the inclined portion 14D or 14E of the oscillating body 14 to the flat portion 14C. The moving body 14 and the movable body 12 can move leftward or rightward at a stretch.

  As described above, according to the present embodiment, the opening / closing device includes a substantially plate-like fixed body, a movable body that is mounted on the upper surface of the fixed body so as to be movable in a predetermined direction, and is disposed between the fixed body and the movable body. The oscillating body and a pressing body that is biased by a spring and elastically contacts the oscillating body are configured such that one end of the oscillating body is slidably engaged with the movable body and the other end is formed substantially flat. The flat part and the inclined part that falls outward on both ends of the flat part. When the movable body is stationary in the open state or the closed state with respect to the fixed body, When the movable body is moved from this state, the swinging body swings, and the pressing body slides from one inclined part to the other inclined part via the flat part. Therefore, it is not necessary to move the movable body 12 by hand to a position exceeding the middle of the total movement amount, and the right and left inclined portions Since the movable body 12 automatically moves to the left or right direction only by moving by 4D or 14E without applying any force thereafter, the opening / closing operation can be performed quickly and with a good feel. .

(Embodiment 2)
A second embodiment of the present invention, particularly the invention according to claim 2, will be described.

  In addition, the same code | symbol is attached | subjected to the part of the structure same as the structure of Embodiment 1, and detailed description is abbreviate | omitted.

  FIG. 7 is a partial cross-sectional perspective view of a switchgear according to a second embodiment of the present invention, FIG. 8 is an exploded perspective view thereof, in which 11 is a substantially plate-like fixed body, and 12 is a movable body. The sliding member 13 is attached to both ends of the movable body 12, and the movable body 12 is mounted on the upper surface of the fixed body 11 via the sliding member 13 as in the first embodiment.

  Reference numeral 14 denotes an oscillating body disposed between the fixed body 11 and the movable body 12 so as to be able to oscillate left and right around the fulcrum hole 14A at one end. The fulcrum hole 14A is a through hole 12A of the movable body 12. 16A is a ring that is rotatably locked to the lower surface by the rivet 15A at its left through hole 14B, and the end surface on the other end side of the fulcrum hole 14A is flat. As in the first embodiment, the left and right ends of the flat portion 14C are formed in the inclined portions 14D and 14E that are lowered on the outer side.

  Reference numeral 16B denotes a ring that elastically contacts one inclined portion 14D of the rocking body 14, and is locked to the through hole 17A at the tip of the pressing body 17 by a rivet 15B, and 16C rotates and slides along the square hole 11C. As in the case of the first embodiment, the ring is a ring that can be locked to the through hole 17A at the tip of the pressing body 17 by a rivet 15B, as in the case of the ring 16B.

  Next, 18A includes a substantially arc-shaped bent part 19D between the linear first arm part 19A and the second arm part 19B, and a substantially arcuate part between the second arm part 19B and the third arm part 19C. An arc-shaped bent portion 19E is provided, and the arm portions 19A to 19C are substantially the same length and are arranged side by side, and are plate-like springs that are N-shaped when viewed from above.

  Reference numeral 18B denotes a plate-like spring having an N-shape in a top view similar to the spring 18A, and is arranged symmetrically with respect to the pressing body 17. The right spring 18A has a rivet 15E at the right end of the third arm portion 19C. Therefore, the left end of the first arm portion 19A is rotatably locked to the pressing body 17 via the through-hole 17B by the rivet 15D. The left spring 18B has a first arm portion 19A with a rivet 15F at the right end via a through hole 17C to the pressing body 17 and a third arm portion 19C with a rivet 15G at a through hole 11E through the through hole 11E. It is locked.

  Here, since the springs 18A and 18B are in a locked state in which the bent portions 19D and 19E between the adjacent arm portions are slightly expanded, a spring force that naturally returns to the direction in which the springs 18A and 18B are closed occurs. Instead of the spring 18 of the first embodiment, the pressing body 17 is pressed against the inclined portion 14D side of the oscillating body 14 by this spring force.

  Here, since the springs 18A and 18B are formed from a metal plate such as a steel plate or a copper alloy, a desired spring force can be obtained by changing the thickness, width and length of the metal plate, and the number of bendings. Further, since the space between the fixed body 11 and the movable body 12 can be effectively utilized because the space between the pressing body 17 and the left and right spaces can be used, the dimensions can be larger than those of the spring 18 of the first embodiment. Therefore, there is an advantageous effect that the degree of freedom in design for obtaining a desired spring force is high.

  9A, in the state where the movable body 12 overlaps the fixed body 11, the ring 16B at the distal end of the pressing body 17 is in elastic contact with the inclined portion 14D of the rocking body 14, Since the oscillating body 14 is tilted leftward, the movable body 12 is urged rightward, and the lower left end of the flat portion 14C is in elastic contact with the protruding portion 12B projecting downward from the lower surface of the movable body 12. And the movable body 12 is still in a state of being overlapped.

  Further, when the movable body 12 moves to the left from this state, as shown in FIG. 9B, the swinging body 14 locked to the lower surface of the movable body 12 by the lower fulcrum hole 14A moves the fulcrum hole 14A. Since it moves to the left together with the movable body 12 while swinging to the right as a fulcrum, the inclined portion 14D and the ring 16B elastically contacting with it move upward, and the springs 18A and 18B rotate at the positions of the rivets 15D to 15G. However, the bent portions 19D and 19E further expand, and the spring force that urges the pressing body 17 toward the swinging body 14 is stored.

  Further, in FIG. 10A, when the movable body 12 further moves to the left, the ring 16B moves onto the flat portion 14C, and the springs 18A and 18B that are spread out naturally cause the pressure of the distal end of the pressing body 17 to be restored. While the ring 16B rotates, the movable body 12 slides and moves at a stroke without applying a force to slide the movable body 12 to the left by elastically sliding on the flat portion 14C in the right direction.

  At this time, the ring 16A locked to the left end of the rocking body 14 moves on the inner surface of the sliding contact portion 11B, and the lower right end of the flat portion 14C is in elastic contact with the protrusion 12C of the movable body 12. The flat portion 14C can maintain a downward inclination.

  Then, as shown in FIG. 10 (b), the ring 16B at the tip of the pressing body 17 comes into elastic contact with the inclined portion 14E of the oscillating body 14, and the movable body 12 is held in a stationary state moved leftward.

  On the contrary, when the movable body 12 is moved to the right from the above state, when the ring 16B is in a position of elastic contact with the flat portion 14C from the inclined portion 14E of the oscillating body 14, the springs 18A and 18B Due to this spring force, the movable body 12 moves rightward at once, and the fixed body 11 and the movable body 12 shown in FIG.

  Here, when the movable body 12 moves in the right direction, as shown in FIGS. 11A and 11B, the ring 16B rotates and slides leftward on the flat portion 14C. The ring 16A at the left end of the oscillating body 14 is in elastic contact with the outer surface of the sliding contact portion 11B, and rotates and slides rightward on the outer surface of the sliding contact portion 11B.

  In the above description, the configuration of the springs 18A and 18B has been described as a plate spring having an arm portion 19A to 19C and bent portions 19D and 19E, and a substantially N-shaped plate spring. Without limitation, there are two arm portions and one bent portion having a substantially U shape in top view, and four arm portions and three bent portions having a substantially W shape. According to this, there is an effect that the degree of freedom of design according to the space in which the leaf spring in the fixed body 11 can be arranged is improved.

  As shown in FIG. 12, instead of the springs 18A and 18B and the pressing body 17, the spring portions 25A and 25B and the pressing body 25C may be integrated into a spring 25. According to this, the ring is attached to the pressing body 25C. By locking 16B and 16C, the opening / closing operation described in the present embodiment can be performed, and a rivet for locking the pressing body and the spring is not necessary, and assembly can be easily performed. And it has the advantageous effect that it can be manufactured at low cost.

  As described above, according to the present embodiment, the configuration using the springs 18A and 18B bent a plurality of times makes it possible to quickly and satisfactorily perform a feel operation and to easily adjust a desired stress load as a spring. Therefore, a thin switchgear can be easily realized because it can be made thinner than the coiled spring.

  In any of the embodiments, it has been described that the ring 16B is locked to the pressing body 17 and this moves from the inclined portion 14D on the rocking body 14 to the inclined portion 14E via the flat portion 14C. Instead of the ring 16B, a configuration in which the tip of the pressing body 17 is directly elastically contacted with the inclined portion 14D, the flat portion 14C, or the inclined portion 14E of the oscillating body 14 is possible, and according to this, the ring 16B is unnecessary. It is simple and can be manufactured at low cost.

  In the above description, the flat portion 14C has been described. However, in any of the embodiments, the sliding portion may have a slightly depressed central portion or a protruding shape. The present invention can be implemented as long as it has a slope toward the top.

  The switchgear according to the present invention can obtain a device that can be operated quickly and with a good touch, and is useful as a switchgear for various electronic devices.
