  FIG. 3 is an assembled perspective view showing the configuration of the first embodiment of the sliding device 10 of the casing of the first form of the present application shown in FIG. 2. The housing slide device 10 according to this embodiment includes a slide device main body 30, an annular component 24, and an assist spring member 18. In this embodiment, a fixed housing side mounting plate 41 is inserted as a first mounting plate between the slide device main body 30 and the side surface 1S of the fixed housing 1, and the side surfaces of the slide device main body 30 and the movable housing 2 are inserted. Although the movable housing side mounting plate 42 is inserted as the second mounting plate between 2S, an embodiment without these is also possible. The shapes of the fixed housing side mounting plate 41 and the movable housing side mounting plate 42 are the same as the shapes of the side surfaces 1S and 2S of the fixed housing 1 and the movable housing 2.

  The slide device body 30 is formed with a recess 34 having a bottom surface 33 on the side surfaces 1S and 2S of the fixed housing 1 and the movable housing 2. The shape of the concave portion 34 is an oval shape, and semi-columnar guide members 35 are projected from both ends of the bottom surface 33. A gap is formed between the curved surface of the guide member 35 and both ends of the recess 34, and this gap serves as a movement passage 37 for moving a connecting member 27 of the annular component 24 described later. The rectangular bottom surface 33 sandwiched between the two guide members 35 is provided with a first slit 31 and a second slit 32 in parallel with the longitudinal direction of the slide device main body 30. In addition, a linear protrusion 36 having a length shorter than the lengths of the first and second slits 31 and 32 is formed in a portion sandwiched between the first slit 31 and the second slit 32 of the bottom surface 33. However, the slide guide 36 is provided so as to protrude in parallel to the first and second slits 31 and 32.

  The annular component 24 includes a first slide member 25 and a second slide member 26 having the same length and a rectangular parallelepiped shape, and a connection member 27 that connects the first and second slide members 25 and 26. The whole is circular. The lengths of the first and second slide members 25 and 26 are shorter than the length of the slide guide 36. The connecting member 27 is a belt-like member in this embodiment, but may be a linear member using a wire or the like. The annular component 24 can be integrally formed by cutting out the first and second slide members 25, 26 and the connecting member 27 from a synthetic resin plate. Alternatively, the first and second slide members 25 and 26 and the connection member 27 are prepared separately, and the connection member 27 is connected to the first and second slide members 25 and 26. Can be made. The total length of the first and second slide members 25, 26 and the connection member 27 is the same as the inner circumference of the recess 34, and the first and second slide members 25, 26 are inserted into the moving passage 37 and the first and second slide members 25, 26 are combined. The second slide members 25 and 26 are accommodated in the recess 34. The length of the first and second slide members 25 and 26 in the short direction is larger than the width of the first and second slits 31 and 32 in the short direction.

  The first and second slide members 25 and 26 of the annular component 24 housed in the recess 34 of the slide device main body 30 have screws 29 inserted through the screw holes 28, so that the fixed housing side mounting plate 41 and the movable housing are inserted. It is attached to the body side mounting plate 42. After the screw 29 is inserted into the screw hole 28, the screw 29 passes through the first and second slits 31 and 32 and is screwed into the screw hole 49 provided in the fixed housing side mounting plate 41 and the movable housing side mounting plate 42. Is done. When the first and second slide members 25 and 26 are attached to the fixed casing side mounting plate 41 and the movable casing side mounting plate 42, the first and second sections are closed with the fixed casing 1 and the movable casing 2 closed. The slide members 25 and 26 are positioned adjacent to the two guide members 35 in the recess 34. The first and second slide members 25, 26, the fixed casing side mounting plate 41 and the movable casing side mounting plate 42 are connected with screws 29 from the fixed casing side mounting plate 41 and the movable casing side mounting plate 42 side. It can also be inserted.

  The assist spring member 18 includes a tension spring 19 that is an elastic body and a piece member 20 that is swingably attached to both ends of the tension spring 19. The diameter of the piece member 20 is larger than the width of the tension spring 19 in the short direction. For example, as shown in FIG. 4A, the piece member 20 is formed by cutting a part of a disk-shaped main body 23 into an arc shape to form a notch portion 21, and the vicinity of the outer peripheral portion of the main body 23 of the notch portion 21. A post 22 is provided in a protruding manner. The hook portion 19H of the tension spring 19 is attached to the post 22. FIG. 4B shows a configuration of the tension spring 19 shown in FIG. 4A and the piece members 20 attached to both ends thereof. Since the hook portion 19 </ b> H of the tension spring 19 is only hooked so as not to come off the post 22 of the piece member 20, the piece member 20 can swing with respect to the tension spring 19. As described above, the piece member 20 has a hook portion (post 22) capable of locking the hook portion 19H of the spring 19 in a part thereof, and when the portion for locking the piece member 20 is replaced as will be described later. In addition, a circular shape or the like is good so that rolling is good.

  In a state where the first and second slide members 25 and 26 are attached to the fixed housing side mounting plate 41 and the movable housing side mounting plate 42, in this embodiment, between the slide guide 36 and the first slide member 25. There is a gap through which the tension spring 19 can be inserted. There is no gap in which the tension spring 19 can be inserted between the slide guide 36 and the second slide member 26. In the assist spring member 18 of this embodiment, one of the piece members 20 is locked to one end h of the slide guide 36, the other is locked to the end M of the first slide guide 25, and the tension spring 19 is moved to the slide guide. It inserts in the clearance gap between 36 and the 1st slide member 25, and attaches in the recessed part 34. FIG.

  FIG. 5 shows the slide device 10 of the case when the slide device 10 having the structure shown in FIG. 3 is installed in the slide type information terminal 5 and the movable case 2 opens with respect to the fixed case 1. The operation will be described by dividing it into six stages from stage (1) to stage (6). In this description, in order to clearly indicate the positions of the fixed housing 1 and the movable housing 2 and the slide device 10 of the housing, the length of the slide device 10 in the height direction of the housing is drawn smaller than the actual length. is there. Actually, when the fixed housing 1 and the movable housing 2 are closed, the sliding device 10 of the housing is formed in the same size as the side surfaces of the fixed housing 1 and the movable housing 2.

  Further, the fixed casing side mounting plate 41 and the movable casing side mounting plate 42 described in FIG. 3 move together with the fixed casing 1 and the movable casing 2, respectively. And the reference numerals of the movable casing side mounting plate 42 are omitted. Further, the movable housing 2 opens with respect to the fixed housing 1 from the stage (1) to the stage (6). In this description, in order to make the operation of the slide device 10 of the housing easier to understand, the slide device body The position of 30 is fixed. Steps (1) to (6) show how the fixed housing 1 and the movable housing 2 move to the left and right with respect to the fixed slide device main body 30.

  As shown in stage (1) of FIG. 5, in the initial state where the fixed housing 1 and the movable housing 2 are closed, one of the piece members 20 attached to both ends of the tension spring 19 is the slide guide 36. The other end is locked to one end M of the first slide member 25. In this state, the tension spring 19 is pulled, and the piece member 20 pushes the end h of the slide guide 36 and the end M of the first slide member 25. Therefore, in a state where the movable casing 2 overlaps the fixed casing 1, the movable casing 2 applies a force in a closing direction through the first slide member 25, the connection member 27, and the second slide member 26 from the tension spring 19. The movable casing 2 receives a biasing force in a direction that does not open with respect to the fixed casing 1. That is, in an initial state in which the fixed casing 1 and the movable casing 2 are closed, an assist spring member 18 including a tension spring 19 and a piece member 20 assists the movable casing to be closed with respect to the fixed casing 1. Power works.

  Step (2) shows the initial state of the opening operation in which the movable casing 2 moves in the opening direction with respect to the fixed casing 1. In the initial state of the opening operation, one of the piece members 20 is locked to the end h of the slide guide 36 and the other is locked to the end M of the first slide member 25. However, the tension spring 19 is extended by the movement of the first slide member 25 in the opening direction, and the urging force applied from the piece member 20 to the end M of the first slide member 25 is increased. The urging force at this time is obtained by adding the urging force of the spring constant of the tension spring 19 × the elongation amount to the force in the closing direction due to the tension in the initial state of the tension spring 19.

  In step (3), the movable casing 2 moves further in the direction of opening with respect to the fixed casing 1, and one of the piece members 20 locked to the end h of the slide guide 36 engages the other piece member 20. The transient state which came to the position of the edge part H on the opposite side to the edge part M of the 1st slide member 25 to stop is shown. The transient state is a state immediately before the piece members 20 at both ends of the tension spring 19 are locked to both ends H and M of the first slide member 25. Although the tension spring 19 is extended to the maximum extent, in a transient state, one of the piece members 20 is locked to both the end h of the slide guide 36 and the end H of the first slide member 25 adjacent thereto. . As a result, the urging force applied from the piece member 20 to the end M of the first slide member 25 is halved.

  In the stage (4) in which the movable casing 2 is further moved in the opening direction with respect to the fixed casing 1 from the transient state in the stage (3), one of the piece members 20 is moved from the end h of the slide guide 36 to the first slide. It comes to be locked to the end H of the member 25. The other of the piece members 20 remains locked to the end M of the first slide member 25. Therefore, the urging force of the tension spring 19 is applied to both ends of the first slide member 25 through the piece member 20, and the tension spring 19 is interposed between the first slide member 25 and the slide device main body 30. The biasing force stops working. This state is called a neutral state. In the neutral state, the movable casing 2 opens with respect to the fixed casing 1 without receiving a biasing force from the assist spring member 18. Actually, a frictional force is generated between the piece member 20 and the slide guide 36, but the frictional force is ignored here.

  In the stage (5) in which the movable casing 2 is further moved in the opening direction with respect to the fixed casing 1 from the neutral state in the stage (4), the end M of the first slide member 25 is opposite to the slide guide 36. A position in line with the end m is reached and a second transient state is reached. In the second transition state, one of the piece members 20 is locked to both the end portion M of the first slide member 25 and the opposite end portion m of the slide guide 36 adjacent thereto. As a result, a biasing force is applied from the piece member 20 to the end portion H of the first slide member 25. By this urging force, an urging force in an opening direction with respect to the fixed casing 1 is applied to the movable casing 2 through the first slide member 25, the connection member 27, and the second slide member 26. That is, in a state immediately before the movable casing 2 is completely opened with respect to the fixed casing 1, the movable casing 2 is moved relative to the fixed casing 1 by the assist spring member 18 including the tension spring 19 and the piece member 20. The assist force in the opening direction works.

  When the movable casing 2 further moves in the opening direction with respect to the fixed casing 1 from the second transient state of the step (5), one of the piece members 20 is locked to the end m of the slide guide 36, and the piece member The other of 20 is locked to the end H of the first slide member 25. The tension spring 19 contracts from the maximum extension state, but extends from the initial state, and the assisting force works in the direction opposite to the initial state, so that the movable casing 2 opens smoothly with respect to the fixed casing 1. Heading to the end of opening operation.

  Stage (6) is a state where the opening operation has been completed, and shows a state where the movable casing 2 is completely opened with respect to the fixed casing 1. In step (6), one of the piece members 20 is locked to the end m of the slide guide 36, the other of the piece members 20 is locked to the end H of the first slide member 25, and the tension spring 19 is initially Return to state. In the open operation end state, the assisting force in the opening direction is applied to the movable casing 2 with respect to the fixed casing 1, so that the movable casing 2 is not easily closed with respect to the fixed casing 1.

  FIG. 6 shows a change in the urging force of the slide assist operation by the assist spring member 18 from the stage (1) to the stage (6) shown in FIG. In step (1), a rightward biasing force, that is, a biasing force in the closing direction, is acting on the movable casing 2. This urging force becomes large in the stage (2) and becomes 0 in the transient state of the stage (3), and no urging force is applied to the movable housing 2 in the stage (4) (the frictional force is ignored). In step (5), the second transition state is entered, and this time, a leftward biasing force, that is, a biasing force in the opening direction, acts on the movable casing 2, and this state is the movable casing 2 being fixed. To the fully open stage (6).

  Thus, according to the slide device 10 of the housing of the first embodiment, when the movable housing 2 fully slides with respect to the fixed housing 1, the first and second slides in the slide device main body 30. Since the positional relationship between the members 25 and 26 is uniquely determined, there is no backlash. Further, according to the slide device 10 of the housing of the first embodiment, the assist force by the assist spring member 18 works in the opening direction in the vicinity of the end of the opening operation, and in the closing direction in the vicinity of the end of the closing operation. Open / close operation can be performed.

  FIG. 7A shows a closed state of the slide type information terminal 5A to which the second embodiment of the slide device 10 of the casing of the first form of the present application shown in FIG. 2 is attached. . In the slide device 10 of the housing of the second embodiment, the first slide member 25 and the second slide member 26 housed in the slide device main body 30A are connected by a strong connection member 27A such as a leaf spring. ing. In this case, the first and second slide members 25 and 26 and the connecting member 27A do not need to be annular parts. This is because by strengthening the connection member 27A, the left and right movements of the first slide member 25 are directly transmitted to the second slide member 26 by the connection member 27A.

  Further, the connecting member 27A in the second embodiment of the sliding device 10 of the housing can be configured by a flexible member such as the connecting member 27 in the first embodiment. In this case, the slide device 10 of the housing is attached to both sides of the slide type information terminal 5A. In the sliding device 10 of one housing, the connecting member 27A is connected between the end portions MN of the first and second sliding members 25 and 26, and in the sliding device 10 of the other housing, the connecting member 27A is connected between the end portions GH of the first and second slide members 25, 26. In this configuration, during the opening / closing operation of the movable casing 2 with respect to the fixed casing 1, a pulling force acts on the connecting member 27A in the sliding apparatus 10 of either one of the casings, so that the sliding apparatus 10 of the casing can be smoothly operated. Operate.

  FIG. 7B shows an open state of the slide type information terminal 5B to which the third embodiment of the slide device 10 of the casing of the first form of the present application shown in FIG. 2 is attached. . In the slide device 10 of the housing of the first embodiment, the assist spring member 18 including the tension spring 19 and the piece member 20 housed in the slide device main body 30 is provided between the slide guide 36 and the first slide member 25. It was attached to.

  FIG. 10 shows the embodiment shown in FIG. 9 when the movable casing 2A of the slide type information terminal 6 in which the sliding device 11 of the casing of the second form of the present application is installed is opened with respect to the fixed casing 1A. The operation of the sliding device 11 of the housing will be described in six steps from step (1) to step (6). In this description, illustration of the fixed casing 1A and the movable casing 2A is omitted, and only the fixed casing side mounting plate 41A and the movable casing side mounting plate 42A that perform the same movement as the fixed casing 1A and the movable casing 2A are shown. It is. Further, in order to clearly indicate the positions of the fixed housing side mounting plate 41A, the movable housing side mounting plate 42A, and the slide device 11 of the housing, the length in the height direction of the slide device main body 30 is drawn smaller than the actual length. .

  As shown in stage (1) of FIG. 10, in the initial state in which the slide type information terminal 6 is closed, the fixed casing side mounting plate 41A and the movable casing side mounting plate 42A are in a state of overlapping in the vertical direction. 43 is accommodated in the groove 44. Steps (2) to (4) show a state in which the fixed housing side mounting plate 41A and the movable housing side mounting plate 42A gradually open from the state of the step (1). In order to make the operation of the slide device 11 easy to understand, the position of the slide device main body 30 is fixed. Then, the fixed housing side mounting plate 41A and the movable housing side mounting plate 42A move to the left and right according to the opening operation of the fixed housing 1A and the movable housing 2A with respect to the fixed slide device body 30. Are shown in steps (1) to (6).

  Steps (2) to (4) are states in which the fixed housing side mounting plate 41A and the movable housing side mounting plate 42A gradually open from the state of step (1). In this state, the slide plate 43 is It remains housed in the groove 44. On the other hand, as shown in step (5), when the fixed casing side mounting plate 41A and the movable casing side mounting plate 42A are fully opened, the movable casing side mounting plate 42A is moved over the tapered surface 47 of the fixed casing side mounting plate 41A. The tapered surface 48 slides down. At the same time, the slide plate 43 accommodated in the groove 44 is lowered in the groove 44. Since the slide plate 43 accommodated in the groove 44 is urged in the direction of exiting the groove 44 by an elastic body 45 such as a compression spring, the slide plate 43 smoothly descends in the groove 44.

  When the slide plate 43 is lowered in the groove 44, the position of the slide plate 43 does not change when viewed from the slide device main body 30, so that the mounting plate main body 40 of the fixed housing side mounting plate 41A is biased by the elastic body 45. As a result, the slide device body 30 is raised. The state in which the mounting plate main body 40 is fully raised with respect to the slide device main body 30 is step (6). In this state, the upper surface of the fixed housing side mounting plate 41A and the upper surface of the movable housing side mounting plate 42A coincide with each other. The slide type information terminal 6 becomes fully flat as shown in FIG. In this embodiment, the inclination angle α of the taper surface 47 of the fixed housing side mounting plate 41A and the taper surface 48 of the movable housing side mounting plate 42A is 45 degrees with respect to the vertical line, and the inclination angle β of the groove 44 is with respect to the vertical line. 30 degrees on the opposite side.

  As described above, when the movable casing 2A of the slide type information terminal 6 in which the sliding device 11 of the casing of the present application is installed is opened with respect to the fixed casing 1A, the movable casing 2A is fully opened. The body 2A descends with respect to the fixed housing 1A together with the slide device 11 of the housing, and becomes full flat. That is, the fixed casing 1A is lifted up and becomes full flat. This is because, as shown in FIGS. 9 and 10, there is a lift-up spring (elastic body) 45 in the groove 44 of the mounting plate main body 40, which is suppressed when the movable casing 2A is slid closed. When the slide opens, it is released and lifted up.

  On the other hand, when the slide is opened to close the movable casing 2A from the opened state, the inclination angles are set to both the tapered surfaces 7 and 8 where the fixed casing 1A and the movable casing 2A are in contact and the moving direction of the slide plate 43 of the groove 44. Because it has, it can be closed smoothly. That is, since the inclined surface angle is given so that the movable casing 2A is on the upper side with the tapered surfaces 7 and 8 where the fixed casing 1A and the movable casing 2A are in contact with each other, the movable casing 2A is slid horizontally. By the closing operation, it is possible to apply a force in the downward direction to the fixed housing 1A.

  At this time, as the inclination angle of the tapered surfaces 7 and 8 becomes sharper like a wedge, the force to push down the fixed housing 1A is larger, but the taper surfaces 7 and 8 of the fixed housing 1A and the movable housing 2A The height of the casing of the portion becomes thin, and it becomes difficult to dispose internal parts such as a display to the end. On the other hand, if the inclination angle of the taper surfaces 7 and 8 is increased, the force to push down the fixed casing 1A when the movable casing 2A is closed becomes weak. However, in the present embodiment, an inclination angle is also given to the sliding direction (lift shaft) of the slide plate 43 in the groove portion 44 provided in the mounting plate main body 40. For this reason, even if the inclination angles of the tapered surfaces 7 and 8 are relatively large (45 degrees), the difference (15 to 0 degrees) from the lift shaft (30 to 45 degrees) is small, and the movable housing 2A is closed. Sometimes, it can be closed smoothly by applying a force for efficiently pushing down the fixed housing 1A.

  Here, the angle of the full flat structure in the 2nd form of this application is demonstrated. As shown in FIG. 11A, the angle of the taper surfaces 47 and 48 of the fixed housing side mounting plate 41A and the movable housing side mounting plate 42A that are in contact at the time of full flatness is α, and the lift of the fixed housing side mounting plate 41A that is lifted up. Let β be the angle between the axis and the vertical axis. As described above, the fixed casing side mounting plate 41A is integral with the fixed casing 1A, and the movable casing side mounting plate 42A is integral with the movable casing 2A. The movable casing side mounting plate 42A indicates the movable casing 2A.

In addition, a force that pushes the movable housing side mounting plate 42A when sliding and closing is A, a force that acts on the fixed housing side mounting plate 41A by the taper surface 48 thereof is B, and a lift that pushes down the fixed housing side mounting plate 41A by the force B. When the magnitude of the axial force is C, the following equation holds.
B = A cos α (1)
C = B cos (α−β) (Formula 2)

As shown in FIG. 11B, when the thickness of the movable housing side mounting plate 42A is P, an acute angle portion is formed by the angle α of the tapered surface 48, and a dead space Q in which components cannot be arranged to the end is generated. Similarly, the fixed housing side mounting plate 41A also has a dead space R in which the fixed housing side mounting plate 41A is shifted laterally during lift-up because the movement axis (lift shaft) in the groove 44 of the slide plate 43 is inclined. These are determined by the angles α and β and are as follows.
Q = P / tan α (Equation 3)
R = Ptanβ (Equation 4)

  12 to 13 are graphs of the above formulas (1) to (4) in the range of angles of 0 to 90 degrees, respectively. For simplification, A = 1 and P = 1. As can be seen from the graph in FIG. 12, the dead space Q is preferably small and preferably equal to or less than the thickness. When Q ≦ 1, α = 45 to 90 degrees is preferable. As can be seen from FIG. 13, the dead space R is preferably small, and if R ≦ 1, the range of β = 0 to 45 degrees is preferable.

  Further, the graph shown in FIG. 14 is a graph in the range of β = 0 to 90 degrees with respect to α = 75 degrees, 80 degrees, 45 degrees, 30 degrees, and 15 degrees. It can be seen that the greater the force acting when pushing down, the better the angle α. However, when the angle α becomes an acute angle from FIG. 12, the dead space Q becomes large. From the balance of both, an angle near α = 45 degrees is appropriate. The graph shown in FIG. 15 is an enlarged graph of the angle β and the force C when α = 45 in FIG. From FIG. 14, it is understood that β = 30 to 60 degrees may be set if the force C is in the range of 95% of the maximum value.

When the conditions shown in FIGS. 12 to 15 are combined, it can be seen that the angles α and β are preferably within the following ranges.
α = near 45 degrees β = range of 30-45 degrees

  From the above, in the embodiment shown in FIG. 10, the sliding device 11 of the housing is configured with the angle α being 45 degrees and the angle β being 30 degrees.
