A closed state in which the first housing and the second housing overlap so that the upper surface of the first housing is covered with the second housing, and the second housing with respect to the first housing There are products on the market that have an opening and closing device that creates an open state in which the upper surface of the first housing is exposed by sliding in the longitudinal direction. As such an opening / closing device for a mobile phone, a device described in Patent Document 1 described below is known.
JP 2003-125052

  The device described in Patent Document 1 attaches a slide case in which a slide cover and a lock plate are overlapped and fixed to a lower surface of a second housing, and also includes a slider that is slidably accommodated in the slide case. By attaching to the upper surface of the housing, the second housing can be slid with respect to the first housing. With such a configuration, all the relative operations of the first housing and the second housing, that is, the slide operation must be performed manually, which is difficult in terms of operability. For this reason, the present applicant has previously proposed an opening / closing device provided with a slide mechanism capable of performing a semi-automatic slide operation.

  The opening / closing device is provided, for example, between a base member attached to the upper surface of the first housing, a slider slidably engaged with the base member, and the base member and the slider. And a biasing means for slidably biasing from a predetermined sliding position to the closing direction and / or the opening direction, and the slider slides from the predetermined sliding position relative to the base member to the closing direction or the opening direction. Since it is biased, the first housing and the second housing can be automatically opened and closed from a predetermined relative slide position.

  In the mobile phone having the opening / closing device, the upper surface of the first housing to which the base member is attached is formed in a flat shape, and the lower surface of the second housing to which the slider is attached is formed in a flat shape, The lower surface of the second housing slides along the upper surface of the first housing in the longitudinal direction in a straight line shape, that is, in parallel. As a result, when this mobile phone is used in the open state, it is difficult to use and sometimes unusable. That is, since the upper surface of the first housing and the lower surface of the second housing are positioned on substantially the same plane in the opened state, for example, the microphone portion is near the rear end portion of the upper surface of the first housing. Since the speaker unit is provided in the vicinity of the front end of the lower surface of the second casing, the speaker unit of the second casing can be connected to the mouth of the microphone unit of the first casing when making a call. I couldn't get close to my ears. In addition, it is difficult to operate the keyboard portion of the first housing while viewing the image displayed on the display unit on the upper surface of the second housing, which is inconvenient.

  Further, in the above-described opening / closing device, since both sides of the slider are slidably engaged with both sides of the base member, the length of the slider (length in the sliding direction) becomes long. That is, since the width of the slider is substantially the same as the width of the base member, it is necessary to increase the length of the slider in order to ensure strength. Thus, when the length of the slider is increased, the length of the base member (the length in the sliding direction) is also increased and the length is increased as a whole.

  Further, the urging means is provided between the base member and the slider. That is, since the urging means is sandwiched between the base member and the slider, the urging means and the urging member are prevented from coming into contact with the base member or the slider when the base member and the slider slide with each other. The clearance between the means and between the slider and the biasing means is increased. As a result, the overall thickness of the slide mechanism is increased.

The rod mounting hole 81f is provided in the sliding portion 81a penetrating from the guide groove 6 when the sliding portion 81a of the slider pin 81 is passed through the guide groove 6 and the stopper portion 81b is brought into contact with the base member 7. Yes. Slider pins 81 are respectively attached to the two guide grooves 6, and the connection rods 82 are respectively inserted into the rod attachment holes 81 f of the slider pins 81, so that the slider member 8 is slidably engaged with the guide grooves 6 to be attached to the base member 7. It can be attached. The connection rod 82 is preferably formed in a rod shape that is longer than the width of the base member 7 and has a length that allows the two first slide pins 44 attached to the second rear casing 31 to engage with both ends. .

  The first slide pin 44 is provided with a slide engagement portion 51 that engages with the connection rod 82 and slides together with the slider member 8. The slide engaging portion 51 is not particularly limited, and is formed, for example, by cutting out from the lower end portion to the substantially central portion thereof in a U-shape at two opposing positions on the peripheral surface of the first slide pin 44. Is preferred. Each of the first slide pins 44 and each of the first rear housings 31 are arranged so that the directions in which the two slide engaging portions 51 face each other with respect to the width direction of the second rear housing 31 are parallel to each other. When the first slide pin 44 and the connection rod 82 are slid along the guide groove 6 by attaching the connection rod 82 to the slide engagement portions 51 of the first slide pins 44 respectively. In addition, the first slide pin 44 can be slid in a curved shape in a side view with respect to the base member 7.

  The base member 7 is attached to the first housing 2 and the slider member 8 is engaged with the second housing 3 so that the first housing 2 and the second housing 3 can slide with each other. 7 may be attached to the second housing and the slider member 8 may be engaged with the first housing so that the first housing and the second housing are slidably engaged with each other. Further, the slider pin 81 is slidably engaged with the guide groove 6, but a guide member is provided in the guide groove 6 so that the slider pin 81 is slidably engaged with the guide member. Good. The guide member is molded from, for example, a synthetic resin such as plastic, but may be formed from other materials such as a sintered metal product or a press-worked product from the viewpoint of durability. Thus, by providing a guide member separate from the base member in the guide groove 6, there is an advantage that the operation feeling of the slider pin and the slider member can be improved and the play can be easily absorbed.

  As shown in FIGS. 2, 4, and 6, the biasing means 9 moves the slider member 8 from the base member 7 in a predetermined opening / closing position, for example, from a neutral position (neutral state) to a closing direction or an opening direction. The slider is biased and provided between the base member 7 and the first housing 2. The biasing means 9 is not particularly limited as long as the slider 3 can be slidably biased with respect to the base member 7 from the predetermined opening / closing position in the opening direction or the closing direction. For example, the biasing means 9 is based on the length of the first housing 2 in the thickness direction. It is preferable that the length of the dimension in the width direction is formed longer to increase the urging force in the width direction.

  Examples of the urging means 9 include a spring 91 having seven winding portions 91a in which a general spring wire is wound once like a torsion spring. Both ends of the spring 91 are formed in, for example, a circular shape, a curved shape, or an arc shape, or an arc shape in the illustrated example, and are respectively rotated to an attachment portion of the spring attachment member and an urging attachment portion 81 c of the slider pin 81. It is pivotally fitted. The spring 91 is applied with an urging force so as to be linear. For example, the winding portion 91a moves the slider member 8 with respect to the base member 7 in accordance with the open / closed position, and the neutral state to the closed state is achieved. The slider member 8 is slid in the closing direction (the direction from the open state to the closed state) during the interval between, and the slider member 8 is opened in the opening direction (from the closed state to the open state) between the neutral state and the open state. It is operated so as to be slid in the direction in which the state is reached.

  Next, the operation of the mobile phone 1 using the opening / closing device A according to the present invention will be described.

  When the cellular phone 1 is not in use, as shown in FIGS. 1A, 2A, and 3A, the first housing 2 and the second housing 3 overlap each other. State. At this time, since the slider member 8 is slid and biased in the closing direction with respect to the base member 7 by the biasing force of the two springs 91, the first casing 2 and the second casing 3 are in the closed state. Is retained. In order to maintain this closed state more reliably, a lock mechanism may be provided.

  In order to make a call or the like using the cellular phone 1, for example, the second casing 3 is pushed and slid in the opening direction while the first casing 2 is fixed. Then, while the positions of both ends of the spring 91 are approaching, a load is applied to the spring 91 and the spring 91 is deformed in a substantially curved shape in the width direction of the mobile phone 1 against the urging force of the spring 91.

  Then, as shown in FIGS. 2B and 3B, when one end of the spring 91 is positioned at a substantially central portion of the guide groove 6, the positions of both ends of the spring 91 are the width of the mobile phone 1. The spring 91 is bent to the maximum, with the distance between both ends thereof being substantially aligned in the direction. At this time, since the positions of both ends of the spring 91 are substantially aligned in the width direction of the mobile phone 1, the urging force of the spring 91 is acting in the substantially width direction of the mobile phone 1, so In contrast, it is difficult for the second housing 3 to slide automatically. This state is a neutral state.

  When the neutral state is passed, one end of the spring 91 moves from the center of the guide groove 6 to the front end, and the positions of both ends of the spring 91 change in the longitudinal direction of the mobile phone 1. Then, since both ends of the spring 91 are urged away from each other by the urging force of the spring 91, the second casing 3 automatically slides in the opening direction with respect to the first casing 2, As shown in FIGS. 1B, 2C, and 3C, the first housing 2 and the second housing 3 are opened and held in that state. As a result, the keyboard portion provided on the upper surface of the first housing 2 is exposed, so that a telephone call and keyboard operation can be performed, and a telephone call or the like can be performed using the mobile phone 1. In order to maintain this open state more reliably, a lock mechanism may be provided. Therefore, the sliding operation can be performed semi-automatically when sliding from the closed state to the open state.

  When the sliding movement is performed in this manner, the upper surface of the first housing 2 is formed as a curved concave surface 41 and the lower surface of the second housing 3 is formed as a curved convex surface. Since the curved convex surface 42 of the second housing 3 overlaps with each other in the longitudinal direction, it slides along these surfaces in a curved shape when viewed from the side, so that the entire mobile phone 1 is in a curved state in the opened state. For this reason, a microphone is provided in the vicinity of the rear end portion of the upper surface of the first housing 2 and a speaker portion is provided in the vicinity of the front end portion of the upper surface of the second housing 3. Sometimes, the microphone part can be brought close to the mouth and the speaker part can be brought close to the ear. In addition, since the display unit 3a is provided on the upper surface of the second housing 3 and the keyboard unit is provided on the upper surface of the first housing 2, the keyboard is viewed while viewing the image displayed on the display unit 3a. This makes it easier to operate the unit and improves usability.

  In order to return the second casing 3 to the original position (closed state) with respect to the first casing 2, for example, the second casing 3 is pushed in the closing direction while the first casing 2 is fixed. Slide. Then, when the positions of both end portions of the spring 91 are minimized and the neutral state is passed, one end portion of the spring 91 moves from the center portion of the guide groove 6 to the rear end portion side, and the positions of both end portions of the spring 91 are carried. It changes in the longitudinal direction of the telephone 1. Then, both ends of the spring 91 are urged away from each other by the urging force of the spring 91, so that the second casing 3 automatically slides in the closing direction relative to the first casing 2. The first housing 2 and the second housing 3 are held in a closed state. Therefore, when sliding from the open state to the closed state, a semi-automatic side-view curved slide operation can be performed.

  Thus, since the slider pins 81 of the slider member 8 are individually provided in the guide groove 6, the overall width of the slider member 8 can be shortened. As a result, the length of the slider member 8 (the length in the sliding direction) can be shortened, and the overall length can be shortened.

  Further, since the spring 91 is provided between the base member 7 and the first housing 2, the overall thickness can be reduced. That is, when one slider is slidably engaged with the two guide grooves of the base member, and the biasing means is provided between the slider and the base member, the slider and the biasing means are provided between the base member and the biasing means. These two clearances must be provided, and the thickness increases. On the other hand, by providing the spring 91 between the base member 7 and the first housing 2, only the clearance between the base member 7 and the spring 91 needs to be provided, so that the overall thickness is reduced. can do.

  Therefore, the mobile phone 1 using the opening / closing device A according to the present invention can be improved in usability and can be shortened in overall length and reduced in thickness.

  Further, since the spring 91 is formed such that the length in the width direction is longer than the length in the thickness direction of the first housing 2 and the urging force in the width direction is increased, the mobile phone 1 The overall thickness can be reduced. That is, when a torsion spring or a compression spring is used, since the biasing force of these springs is determined by the diameter of the coil, the thickness of the spring increases, so the thickness increases. On the other hand, the spring 91 according to the present invention is formed so that the length in the width direction is longer than the length in the thickness direction of the first housing 2 so as to increase the biasing force in the width direction. Since it comprised, thickness can be made thin as width becomes large. As a result, the mobile phone 1 can be made thinner.

  Further, the slider member 8 and the first slide pin 44 are formed on a slide engagement portion 51 formed in a substantially U shape extending in the thickness direction of the mobile phone 1 (also the axial direction of the first slide pin 44). Since the connection rod 82 is inserted and engaged, when the slider member 8 slides linearly along the guide groove 6, the connection rod 82 moves in the axial direction with respect to the first slide pin 44. Meanwhile, the first slide pin 44 slides in a curved shape along the curved concave surface 41. As a result, the second housing 3 can be smoothly slid in a curved shape with respect to the first housing 2. That is, for example, when the slider member is formed in a curved shape and the slider member is slid along the slider member 8, it is difficult for the spring to bias the slider member in the curved shape, and the slider member is curved. Since it is difficult to form accurately, the second housing 3 cannot be smoothly slid in a curved shape with respect to the first housing 2. On the other hand, since the slider member 8 slides linearly along the guide groove 6 of the flat base member 7, the biasing force of the spring 91 acts on the slider member 8 with certainty. The second housing 3 can be smoothly slid in a curved shape with respect to 2.

  As described above, the switchgear according to the present invention forms the upper surface of one housing as a curved concave surface and the lower surface of the other housing as a curved convex surface. Since it has sliding means that slides in a curved shape in side view along these surfaces in the longitudinal direction with the curved convex surfaces of the housing overlapping each other, the usability is improved, and the base member and one housing Since the biasing means is provided between the two, the overall thickness can be reduced, and the slider member has two slider pins that individually engage with the guide grooves. Can be shortened, and is therefore particularly suitable for use in mobile phones among mobile devices.
