An insertion hole 5b through which the main shaft 6 is inserted is provided on the opposite side of the main link 5 from the portion facing the sub link 7. The central axis of the insertion hole 5 b coincides with the central axis of the main shaft 6.

  As shown in FIG. 2, four spring guide shafts 7 a that support the other end of the four springs 9 are provided in a portion of the sub link 7 that faces the main link 5. Further, an insertion hole 7b through which the sub shaft 8 is inserted is provided on the side opposite to the portion of the sub link 7 facing the main link 5. The central axis of the insertion hole 7 b coincides with the central axis of the sub shaft 8.

  Further, the slide mechanism 12 includes four springs 9 positioned in parallel to the center line C connecting the main axis that is the central axis of the insertion hole 5b and the auxiliary axis that is the central axis of the insertion hole 7b. The center line C is parallel to the movement direction SH.

  As shown in FIG. 2B, the spring guide shaft 5 a forms a part of the main link 5. In the width direction W in the plane of the main link 5 and perpendicular to the moving direction SH, the outer spring is located at a position separated from the center line C connecting the center axis of the insertion hole 5b and the center axis of the insertion hole 7b by the first distance L1. A guide shaft 5a is provided. An inner spring guide shaft 5a is provided at a position separated from the center line C by a second distance L2 shorter than the first distance L1.

  As shown in FIG. 2B, the spring guide shaft 7 a forms a part of the sub link 7. In the width direction W perpendicular to the moving direction SH in the plane of the sublink 7, the outer pair is located at a position separated from the center line C connecting the central axis of the insertion hole 7 b and the central axis of the insertion hole 5 b by the first distance L1. The spring guide shaft 7a is provided. Further, an inner spring guide shaft 7a is provided at a position separated from the center line C by a second distance L2 shorter than the first distance L1.

  That is, the spring guide shaft 5a and the spring guide shaft 7a corresponding to the four springs 9 are all configured in parallel with the center line C and in parallel with the moving direction SH shown in FIG. It should be noted that grease is applied to the surface of the four springs 9 according to the degree of request for rust prevention, if necessary.

  As shown in FIG. 2 (B), the main link 5 has an inner sliding piece 5c extending on the center line C from the portion where the insertion hole 5b is formed toward the sub link 7. A pair of outer sliding pieces 5d that are parallel to the sliding piece 5c and shorter in the moving direction SH than the sliding piece 5c are provided outside the sliding piece 5c in the width direction W. The center in the width direction of the sliding piece 5d is provided so as to coincide with a position separated from the center line C in the width direction W by a predetermined distance LC. The distance LC is an average of the first distance L1 and the second distance L2 described above.

  The spring guide shaft 5a is provided at the end of the pair of outer sliding pieces 5d facing the sub link 7.

  Corresponding to this, as shown in FIG. 2B, the sub-link 7 has two strips 7c that extend from the portion where the insertion hole 7b is formed toward the main link 5. . The center in the width direction of each of the two sliding pieces 7c coincides with the center line C and the center in the width direction of the outer sliding piece 5d. Moreover, the width direction dimension of the to-be-slidable piece 7c is formed so that it may correspond with the separation distance of the width direction W of the sliding piece 5c and the sliding piece 5d. The spring guide shaft 7a is provided at a triangular end 7d facing the main link 5 at a portion located on the outer side in the width direction of the pair of sliding pieces 7c.

  The sliding piece 5c, the sliding piece 5d, and the sliding piece 7c are connected to each other so as to be slidable in the moving direction SH, and the sliding piece 5c, the sliding piece 5d, and the sliding piece 7c are connected. As a result, the relative displacement of the main link 5 and the sub link 7 other than the moving direction SH is restricted.

  Furthermore, the slide device 1 </ b> A includes a spring guide case 10. As shown in FIG. 2A, the spring guide case 10 has a configuration in which both sides in the movement direction SH are open and an opening 10b extending in the movement direction SH is formed on the upper side in FIG. 2A. In addition, the four springs 9 and the corresponding four spring guide shafts 5a and 7a are encased, and the sliding piece 5c and the two slid pieces 7c are encased.

  Here, the spring guide case 10 will be described in detail. A locking piece 10 a that protrudes downward from above in FIG. 2B is formed at the upper end in FIG. 2B of the opening end of the spring guide case 10 on the sublink 7 side. A locked hole 7e having a shape that is recessed downward from the upper side in FIG. 2B is formed in the portion 7d. The locking piece 10 a is locked in the locked hole 7 e, and the end of the spring guide case 10 on the sub link 7 side is fixed to the sub link 7.

  On the inner peripheral surface of the spring guide case 10, there is provided a protrusion (not shown) extending in the movement direction SH for restricting displacement in the width direction W of the spring 9 installed on each side in the width direction W. The shape portion is slidably engaged with the groove portion 5e extending in the movement direction SH in the vertical direction of FIG. 2B of the sliding piece 5d of the main link 5, that is, on both sides in the thickness direction. At the same time, the inner peripheral surface of the spring guide case 10 is slidably in contact with the surface on the outer side in the width direction from the groove 5e of the sliding piece 5d of the main link and the outer end surface in the width direction. Further, the spring guide case 10 is slidably supported by the sliding sheet 14 from the lower side shown in FIG.

  As a result, the main link 5 and the spring guide case 10 are slidably connected in the movement direction SH. At the same time, the sliding piece 5c and the sliding piece 5d and the sliding piece 7c are slidably engaged with each other and further encased by the spring case 10, so that the main link 5 and the sub link 7 are Restricting means for restricting relative displacement other than the moving direction SH is configured. By this restricting means, the relative displacement other than the moving direction SH between the main link 5 and the spring guide case 10, particularly the torsional displacement around the sliding direction SH is restricted. Further, the sub-link 7 side of the spring guide case 10 is detachably fixed to the sub-link 7 when the locking piece 10a is locked in the locked hole 7e.

  The spring guide case 10 has open ends in both the movement directions SH, and a lip seal (not shown) is provided between the open end and the surface of the main link 5 and between the surfaces of the sub links 7. As necessary, a space in which the spring 9 is accommodated and a space outside the spring guide case 10 are liquid-tightly defined as necessary.

  According to the slide device 1A of the first embodiment described above and the slide mechanism 12 included in the slide device 1A, the following operational effects can be obtained. That is, as shown in FIG. 3, the sub-link 7 and the main link 5 that are moved close to and away from each other in the direction of the center line C, that is, the moving direction SH in accordance with the user's sliding operation, The sub-link 7 and the main link 5 are stabilized so that the sub-link 7 and the main link 5 are regulated so as to be positioned on the C by the regulating means constituted by the spring guide case 10, the sliding piece 5c, the sliding piece 5d and the sliding piece 7c. The approaching / separating displacement is secured.

  In other words, the moving direction of the main link 5 and the sub link 7 based on the restriction function of both the spring guide case 10 and the restriction means constituted by the sliding piece 5c, the sliding piece 5d and the sliding piece 7c. Since relative displacement other than SH is restricted, it is assumed that the approaching / separating displacement accompanying the expansion / contraction of the spring 9 of the main link 5 and the sub link 7 is more stable, and the slide operation by the user of the entire slide device 1A and the slide operation are further improved. It can be executed smoothly. More specifically, the relative displacement other than the movement direction SH is more specifically the relative displacement around the movement direction SH, the relative displacement in the direction perpendicular to the movement direction SH, and the relative displacement in the direction around the direction perpendicular to the movement direction SH. Includes displacement.

  In addition, in the slide mechanism 12 of the first embodiment, the four springs 9 can be stored in the internal space defined by the main link 5, the sub link 7 and the spring guide case 10. In comparison, the spring can be configured not to be exposed to the outside. This eliminates the need for the wire constituting the spring 9 to be a rust-proof member such as stainless steel, so that it is possible to select a wire such as a piano wire having higher strength than stainless steel, for example. As a result, the degree of freedom in selecting the reaction force in the first half of the slide and the auxiliary force in the second half of the slide can be increased.

  Furthermore, in the slide mechanism 12 of the first embodiment, since grease is applied to the four springs 9 as necessary, the wire constituting the springs 9 is not a member subjected to rust prevention treatment such as stainless steel, In the case of a wire rod such as a piano wire with higher strength, when the demand for rust prevention is stronger, the generation of rust and corrosion can be more effectively prevented by the rust prevention effect of grease.

  Further, the spring guide case 10 encloses the spring 9, the spring guide shaft 5a, and the spring guide shaft 7a to constitute a restricting means. Therefore, the spring guide shaft 5a that holds the spring 9 and the spring guide shaft 7a include In addition, no function other than holding the spring 9 can be provided. In other words, the spring guide shaft 5a and the spring guide shaft 7a need to have a function of slidably connecting the main link 5 and the sub link 7 in the movement direction SH and a function of regulating relative displacement other than the movement direction SH. Can be eliminated.

  Accordingly, as shown in FIGS. 2 and 3, the length of the spring guide shaft 5a and the spring guide shaft 7a in the moving direction SH is set to a minimum length for supporting the spring 9 in the direction perpendicular to the moving direction SH. It can be. Therefore, in the slide device 51 of the prior art as shown in FIG. 4, the spring guide shaft 55a needs to have a length corresponding to the maximum displacement in the moving direction SH of the main link 55 and the sub link 57. Although the length of the shaft 55a has been increased, according to the first embodiment, the spring guide shaft 5a and the spring guide shaft 7a can be made shorter.

  That is, the spring guide shaft 5a is inserted through the sub link 7 and the spring guide shaft 7a is inserted through the main link 5 in the process of changing the relative positions of the main link 5 and the sub link 7 in the moving direction SH accompanying the slide operation. The configuration as shown in FIG. 4 described above can be eliminated.

  As a result, the main link 5 and the sub-block 7 are moved in the movement direction SH when the slide operation shown in FIG. 3A is started and the slide operation shown in FIG. Even with the closest displacement, the interval B in the movement direction SH of the main link 5 and the sub link 7 can be shortened from the interval A shown in FIG. As a result, the end of the spring guide shaft 55a on the sublink 57 side inside the device to which the slide device 1A is applied is on the right side in FIG. 4B, that is, on the sublink 57 side. Can be avoided, interference with the other parts of the sliding device 1A during the sliding operation can be suppressed as much as possible, and the degree of freedom of fitting can be increased.

  In addition to the effects described above, the spring guide case 10 is connected to the sub link 7 side so as to be detachable by locking the locking piece 10a and the locked hole 7e. Since they are movably connected, the spring guide case 10, the sub link 7, and the main link 5 can be made independent from each other.

  As a result, the rotation function of rotating the main shaft 6 in the circumferential direction is shared only by the main link 5, and the rotation function of rotating the sub shaft 7 in the circumferential direction is shared only by the sub link 7. The function of enclosing the outer cover 9 and the restricting function for restricting the relative displacement of the main link 5 and the sub link 7 other than the center line C, that is, the direction of the straight line C, to the spring guide case 10 only, Can be made independent, and the burden of each component can be reduced.

  In particular, since it is possible to eliminate the necessity of providing the spring guide case 10 with the rigidity required to bear the rotation function described above, the spring guide case 10 can be made as light as possible, and the straight line C It is possible to reduce the weight of the spring guide case 10 that extends in a relatively long range in the direction, and further reduce the weight of the slide mechanism 12 and thus the slide device 1A.

  In addition, even when a more effective and appropriate member for enclosing the spring 9 to rust the surface is different from the members constituting the main link 5 and the sub link 7, as described above, the spring guide case 10 and the separate structure of the main link 5 and the sub link 7, it is possible to make it easier to select appropriate members as appropriate, and to increase the degree of design freedom of individual components. be able to.

  Further, by forming the spring guide case 10 with the opening 10b extending in the movement direction SH, molding from the base material can be facilitated.

  In the first embodiment described above, the configuration in which one slide mechanism 12 is provided for one slide device 1A is shown, but a configuration in which two slide mechanisms are provided may be employed. The second embodiment will be described below.

  FIG. 5 is a schematic diagram showing a second embodiment of the slide device and the slide mechanism according to the present invention.

  The slide device 1B according to the second embodiment includes a main plate 2B, a slide plate 4B, and a second slide mechanism 12. The configuration of the slide mechanism 12 itself is the same as that shown in FIG. 1, and the basic configuration and function are the same for the other components, mainly the main plate 2B and the slide plate 4B. Therefore, in FIG. 5, the same reference numerals are given to the components corresponding to those shown in FIGS. 1 and 2, and the description thereof is omitted.

  In the slide device 1B of the second embodiment, as shown in FIGS. 5A and 5B, the second slide mechanism 12 has the main shaft 6 side at the center in the width direction T1-T2 perpendicular to the slide direction S1-S2. Place them close to each other. Similarly, the sub-shaft 7 side of the second slide mechanism 12 is disposed at a position separated from the center in the width direction T1-T2. That is, the two slide mechanisms 12 are arranged in a V shape.

  The main plate 2B included in the slide device 1B has a width direction dimension approximately twice that of the main plate 2A shown in the first embodiment because the two slide mechanisms 12 are arranged in a V shape. The slider plate 4B also has a width direction dimension approximately twice that of the slide plate 4A shown in the first embodiment.

  In the pair of main links 5 of the second slide mechanism 12, the main plate 2 </ b> B is connected to the main shaft 6. At this time, the main link 5 is rotatably connected to a position symmetrical with respect to the center of the main plate 2B in the width direction, and the pair of sub links 7 are connected to the main plate 2B by the sub shaft 7. The sub shaft 7 is also rotatably connected to a line symmetric position with respect to the center in the width direction of the main plate 2B.

  Also in the second embodiment, the same operational effects as those of the slide device 1A and the slide mechanism 12 shown in the first embodiment can be obtained. In addition, in the slide device 1B of the second embodiment, as described above, the slide mechanism 12 approaches the main shaft 6 side and is separated from the sub shaft 7 side in the same plane parallel to the main plate 2B. Since it arrange | positions in the V shape of a form, the following effects can be acquired. By sliding operation, the slide plate 4B moves in the S1 direction from the state of FIG. 5 (A), and after the two pairs of slide mechanisms 12 are directed in the T1T2 direction to be in a straight line, when further pushed in the S1 direction, The slide plate 4B is automatically moved in the S1 direction by the elastic force generated by the slide mechanism 12.

  That is, when the slide plate 4B is slid from the start position shown in FIG. 5A to the end position shown in FIG. 5B in accordance with the user's slide operation, in the first half of the slide, a pair of slide mechanisms The component forces directed in the opposite directions in the width direction T1-T2 in FIG. 5 of the reaction forces generated by the respective twelve can be mutually canceled in the width direction T1-T2. As a result, the slide plate 4B is displaced in the width direction with respect to the main plate 2B due to the component of the reaction force in the width direction as the reaction force originally intended in the slide operation is applied to the user's hand. Can be prevented.

  Similarly, in the latter half of the slide, each of the component forces in the width direction T1-T2 in FIG. 5 of the auxiliary force generated by each of the pair of slide mechanisms 12 is expressed by the pair of left and right slide mechanisms 12 in the width direction T1-T2. It is possible to cancel each other because they are directed in opposite directions. This prevents the slide plate 4B from being displaced in the width direction with respect to the main plate 2B due to the component force in the width direction of the assist force when the intended assist force is applied to the user's hand. be able to.

  As described above, in all aspects from the start to the first half of the slide operation and from the second half to the end, the displacement of the slide plate 4B in the width direction with respect to the main plate 2B is suppressed to make the slide operation smoother. Can do. In addition, it is possible to prevent the user from being given an unintended width direction reaction force or auxiliary force having components other than the sliding direction S1-S2, and to prevent the user from feeling uncomfortable. .

  Further, similar to the one shown in the first embodiment, the slide mechanism 12 itself has a function as an outer member of the spring guide case 10 and a restricting means, and therefore, two pairs in a plane parallel to the main plate 2B. Relative displacements other than the moving direction SH of the main link 5 and the sub link 7 of the slide mechanism 12 can be suppressed.

  Further, in the second embodiment, the pair of slide mechanisms 12 are arranged in a V shape and connected to the two sub-shafts 7 at positions separated from the center in the width direction on the slide plate 4B side. Since the slide mechanism 12 and the slide plate 4B constitute a substantially triangular link mechanism, the following operational effects can be obtained. That is, relative displacement of the slide plate 4B with respect to the main plate 2B other than the slide direction S1-S2 can be prevented as much as possible, and the slide operation can be made smoother.

  Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions are made to the above-described embodiments without departing from the scope of the present invention. be able to.

  For example, in the slide device 1A of the first embodiment described above, the slide direction S1-S2 is the long side direction of the main plate 2A, but the length of the main plate 2A in the slide direction S1-S2 is the width direction T1-T2. When the shape is shorter than the length in FIG.

  Moreover, in the slide mechanism 12 of Example 1 mentioned above, although it has the four springs 9, it is good also as a structure which has two springs 9 instead, and can set suitably about the number of stripes. Is possible. Furthermore, the combination of the number of strips of the three strips 5c and the slide strips 5d and the two strips 7c can be changed as appropriate.

  In addition, the spring guide case 10 of the slide mechanism 12 according to the first embodiment described above is configured such that the upper side in FIG. 2 is opened, but the upper sliding part 5c is not included and the central sliding piece 5c is also encased. It can also be set as the form to do.

  Further, in the above-described embodiment, the application of grease to the spring 9 can be selectively performed when the degree is high according to the degree of request for rust prevention, and the degree of request for rust prevention is low. In some cases, it may not be applied. Similarly, providing a lip seal at the end of the spring guide case 10 in the moving direction SH is also appropriately selected when the degree is high, depending on the degree of sealing required between the space surrounding the spring 9 and the external space. If the degree of sealing requirement is low, the lip seal may not be provided.

  In the above-described embodiment, the main shaft 6 is fixed to the main plate side. However, the main shaft 6 is fixed to the main link 5 side, and the main shaft 6 is inserted into the insertion holes provided on the main plates 2A and 2B. Also good.
