(First embodiment)
FIG. 3 is a schematic perspective view of the floor console provided with the armrest slide mechanism according to the first embodiment. FIG. 1 is a cross-sectional view taken along the line II of FIG. 3 and illustrates the case where the armrest is held at the rearmost position, and FIG. 2 is the same position as the line II of FIG. It is sectional drawing fractured | ruptured, Comprising: The case where an armrest is hold | maintained in the foremost position is illustrated. The floor console 10 on which the armrest AR of the first embodiment is disposed is basically the same as that illustrated in FIG. 13, and is a console body 12 that is injection-molded from a synthetic resin material such as polypropylene (PP). An article storage portion 16 that opens upward is defined in the rear side of the console main body 12, and an installation portion 18 such as a change lever or a drink holder is provided on the front side. A console lid 14 to which the upper opening 16A of the article storage portion is releasably closed and the armrest AR of the first embodiment is attached via the slide unit 40 is disposed at the upper rear side of the console body 12. It is installed.

  The console lid 14 is injection-molded from a synthetic resin material such as polypropylene (PP) as illustrated in FIGS. 1 and 4 and the like, and is sized so that the upper opening 16A of the article storage unit 16 can be completely closed. The lid body 20 has a rectangular tray shape, and a lid cover 22 that is injection-molded from a synthetic resin material such as polypropylene (PP) and is assembled to the lower surface of the lid body 20. And the upper surface of this lid main body 20 functions as the installation part 24 for attaching the slide unit 40. In such a console lid 14, the rear end portion of the lid main body 20 is pivotally supported by a hinge member (not shown) with respect to the rear upper end edge of the console main body 12, and the upper opening portion 16 </ b> A of the article storage portion 16 described above is supported. It opens and closes.

  As shown in FIGS. 1 and 4, the armrest AR includes a rest body 30 that is sized so as to completely cover the console lid 14 described above, and a reverse tray-like rest base that is attached to the lower surface of the rest body 30. 32. The rest main body 30 includes a core material 34 made of a soft urethane foam material foam-molded from a urethane raw material, and a skin material 36 covering the outer upper surface of the core material 34. The core material 34 has moderate elasticity due to the physical properties of the urethane foam, and when the occupant puts his elbow on, the core material 34 is moderately elastically deformed and contributes to improvement in tactile sensation. The skin material 36 is made of a synthetic resin sheet material, synthetic leather, genuine leather, a woven or knitted fabric such as a fabric or a moquette, and contributes to improving the texture and touch.

  As illustrated in FIGS. 4 and 5, the slide unit 40 is attached and fixed to the first guide member 42 that is attached and fixed to the installation portion 24 on the upper surface of the lid body 20 and the lower surface of the rest base 32 described above. The second guide member 44 is made up of. Convex guide rails 46, 46 extending in the front-rear direction of the member 42 are extended at the outer end edges on both sides of the first guide member 42, and the inner end edges on both sides of the second guide member 44 are Recessed guide grooves 48 extending in the front-rear direction of the member 44 are extended. Accordingly, the second guide member 44 can slide with respect to the first guide member 42 by fitting the guide rails 46 and 46 and the guide grooves 48 and 48 so as to be slidable. Accordingly, the first guide member 42 is fixedly attached to the installation portion 24 of the lid main body 20 in the front-rear direction, and the second guide member 44 is fixed to the back side of the rest base 32. By mounting and fixing in a state where the front and rear directions are matched, the armrest AR is attached to the console lid 14, and the armrest AR slides in the front and rear direction on the upper surface of the console lid 14.

  The armrest AR of the first embodiment is provided with a slide support unit 50, and an “automatic drawer type” in which a positive (automatic) slide in the forward direction is expressed with respect to the console lid 14 (floor console 10). " As illustrated in FIG. 5, the slide support unit 50 is rotatably disposed on the follower guide surface 52 having the oblique guide surface 56 provided on the upper surface of the console lid 14 and the lower surface of the armrest AR. The roller 60 is a copying member, and a torsion spring (biasing means) 62 that is disposed on the armrest AR and elastically presses the roller 60 against the driving guide surface 52. Then, the roller 60 moves along the oblique guide surface 56 by the pressing force of the torsion spring 62, so that a force to slide forward with respect to the console lid 14 can be expressed.

  The following two guiding guide surfaces 52 are formed so as to be symmetric with respect to the step end surfaces on both the left and right sides formed by providing the recesses on the upper surface of the first guide member 42 described above. Move (roll) following this. These follower guide surfaces 52, 52 are located on the rear side of the first guide member 42, and extend in parallel with the slide direction of the armrest AR (guide rails 46, 46). It is composed of the above-described oblique guide surface 56 located at the front side of the guide member 42 and extending obliquely at an appropriate angle with respect to the sliding direction of the armrest AR. 56 is bent. In other words, the inclined guide surface 56 extends away from the corresponding roller 60 that rolls as it goes forward of the console lid 14. In other words, as it goes to the front of the console lid 14, the console lid 14 extends away from the pressing direction by the torsion spring 62. In addition, the parallel guide surface 54 and the oblique guide surface 56 which are divided by the bending point P are set to have a long extension length of the oblique guide surface 56.

  As illustrated in FIG. 5, the torsion spring 62 is formed by winding a spring wire such as a piano wire, and has two leg portions 66 and 66 extending from the winding portion 64 into a substantially V shape. The leg portions 66, 66 are displaced in the direction approaching or separating from each other, whereby the winding portion 64 is twisted, and the return elasticity is expressed. The tips of these leg portions 66 and 66 are bent at right angles so as to function as shaft support portions on which the roller 60 described above can be rotatably mounted, and the torsion spring 62 also functions as a roller support member. Have both. Here, when no external force is applied to the legs 66, 66, the distance between the tips of the legs (the distance between the tips of the legs 66, 66) L1 is the distance between the front ends of the respective guide surfaces 52, 52. The distance (distance between the front ends of the inclined guide surfaces 56, 56) L2 is set to be at least equal to or greater than this distance L2. As a result, regardless of the position of the second guide member 44 attached to the first guide member 42, the rollers 60, 60 attached to the leg portions 66, 66 have corresponding movement guide surfaces. When contacting 52, 52, the leg portions 66, 66 are always appropriately deformed in a direction close to each other, so that a pressing force for pressing the roller 60 against the following guide surface 52 is developed. Become. Such a torsion spring 62 is attached to the lower surface of the second guide member 44 described above using the attachment member 70 having the support rod 72 penetrating the winding portion 64, and is hooked on the support rod 72. Held in.

  As described above, the rollers 60 and 60 are rotatably attached to the tip support portions of the leg portions 66 and 66 of the torsion spring 62, and the second guide member 44 is attached to the first guide member 42. Are aligned with the following guide surfaces 52, 52. As described above, the rollers 60 and 60 are always held in a state of being pressed against the follower guide surface 52 by the return elasticity of the torsion spring 62 that is appropriately elastically deformed. Therefore, when the second guide member 44 slides relative to the first guide member 42, the second guide member 44 rolls following the following guide guide surfaces 52, 52 without being separated from the corresponding guide guide surfaces 52, 52. It becomes like this.

  Note that reference numeral 74 in FIG. 5 denotes a guide groove with which the guide pin 76 provided on the attachment member 70 is engaged, and the guide pin 76 moves along the guide groove 74 when the second guide member 44 slides. Thus, the slide amount of the second guide member 44 relative to the first guide member 42, that is, the slide amount W in the front-rear direction of the armrest AR is defined. For example, when the armrest AR is moved to the rearmost position, as illustrated in FIG. 6A, the guide pin 76 comes into contact with the rear end of the guide groove 74, so that the rear of the second guide member 44 (the armrest AR). Movement to the side is restricted. When the armrest AR moves to the foremost position, the guide pin 76 comes into contact with the front end of the guide groove 74 as illustrated in FIG. 6B, so that the front side of the second guide member 44 (the armrest AR) Movement to is regulated.

  When the armrest AR is moved to the rearmost position, as illustrated in FIG. 6A and FIG. 7, the rollers 60, 60 are parallel guide surfaces 54 in the corresponding guide guide surfaces 52, 52. Located in. At this time, the arm rest AR is slid although each leg 66, 66 of the torsion spring 62 is elastically deformed to the maximum in the direction approaching each other and presses the roller 60 toward the parallel guide surface 54 with a considerably strong force. Since the force to be generated is not expressed, it is held in a state stopped at this rearmost position.

  Here, the bending point P between the parallel guide surface 54 and the oblique guide surface 56 is the roller 60 and the following guide surface when the armrest AR is at the rearmost position as illustrated in FIG. The position is separated from the contact position with 52 by a predetermined interval. That is, the substantial effective length of the parallel guide surface 54 is the same as the distance to the bending point P, and when the roller 60 is located at this portion, the armrest AR is pulled forward or pushed backward. If it does not slide, it will stop at that position. That is, the region from the rearmost position to the bending point P is a so-called “manual slide section MS”.

  On the other hand, when the armrest AR is pulled forward until it exceeds the manual slide section MS, the roller 60 moves from the parallel guide surface 54 to the oblique guide surface 56 through the bending point P. As a result, the torsion spring 62 presses the rollers 60, 60 against the corresponding oblique guide surface 56, so that the armrest AR can be moved forward even if the forward pulling is stopped, as illustrated in FIGS. 6B and 8. It will slide positively (automatically) and move to the foremost position. That is, a region from the bending point P to the forefront position is a so-called “automatic slide section AS”.

  Note that the armrest AR stopped at the foremost position is held at this position because the pressing force of the torsion spring 62 acts on the rollers 60 and 60 even in this state. Further, when moving to the rearmost position, the rollers 60 and 60 rotate the oblique guide surface 56 and the parallel guide surface 54 of the driven guide surface 52 by gripping the front side of the armrest AR and pushing it backward. In the process of movement, the torsion spring 62 is elastically deformed, and the armrest AR is allowed to slide.

  Here, as an example of specific set dimensions, when the slide amount W of the armrest AR is set to 100 mm, it is desirable to set the manual slide section MS to about 20 mm and the automatic slide section AS to about 80 mm. With this setting, when the armrest AR at the rearmost position is pulled forward by about 20 mm, the armrest AR will automatically slide to the frontmost position thereafter.

  The armrest AR of the first embodiment configured as described above has the following operational effects. First, when the armrest AR at the rearmost position is slid to the foremost position, the occupant only needs to pull the distance of the manual slide section MS forward by his / her own force. In the automatic slide section AS, the armrest AR Automatically slides forward. Accordingly, since a support function for sliding the armrest AR forward is added, there is an advantage that the slide operability is greatly improved. In addition, the slide support unit 50 for realizing the support function is simply configured with a small number of parts (members) including the follower guide surface 52, the roller 60, and the torsion spring 62 formed on the first guide member 42, thereby reducing the number of parts. There is also an advantage that the manufacturing cost can be greatly reduced by reducing the number of assembling steps. In addition, the use of the torsion spring 62 eliminates the need for a support member for supporting the roller 60 and is effective in reducing the number of components.

  In addition, in the armrest AR of the first embodiment, it is possible to set various advance modes of the armrest AR in the automatic slide section AS by changing the extending form of the oblique guide surface 56 in the following guide surface 52. It is. For example, it is possible to adjust the forward speed of the armrest AR in the automatic slide section AS by changing the extension angle of the oblique guide surface 56 with respect to the slide direction. That is, the advance speed of the armrest AR can be increased as the extension angle of the oblique guide surface 56 with respect to the sliding direction is increased.

  In the embodiment described above, since the extending form of the oblique guide surface 56 is a straight line, the advance speed of the armrest AR in the automatic slide section AS is substantially constant throughout the entire area. With an appropriate curved shape, the forward speed of the armrest AR in the automatic slide section AS can be accelerated or decelerated. For example, if the oblique guide surface 56 is formed in a curved shape as illustrated in FIG. 9, the armrest AR pulled out from the rear side to the automatic slide section AS is first gradually accelerated, and the speed is constant in the middle. In the end, you can gradually slow down.

(Modification of the first embodiment)
FIG. 10 is a plan view schematically illustrating the slide support unit 50 of the armrest AR according to a modification of the first embodiment. As illustrated in FIG. 10A, the armrest AR according to this modified example includes one recessed holding portion 80 that can be temporarily stopped by the roller 60 along the longitudinal direction of the follower guide surface 52. As described above (four in this modification), the armrest AR can be stopped and held at the position where the roller 60 is aligned with the holding portion 80. In other words, the holding unit 80 has a position that aligns with the roller 60 when the armrest AR arrives at the rearmost position, a position that aligns with the roller 60 when the armrest AR arrives at the foremost position, and a distance between these positions. It is formed at each of the two boundary positions when divided into minutes. As a result, as illustrated in FIG. 10B, the armrest AR has the rearmost position, the position advanced by 1/3 from the rearmost position, the position advanced by 2/3 from the rearmost position, and the frontmost position, respectively. Can be temporarily stopped and used. Note that the armrest AR held and held at each position can be easily slid by pulling forward or pushing backward.

  In addition, by increasing / decreasing the setting number of the holding | maintenance part 80 mentioned above, a stop point can be increased / decreased according to the number. Therefore, according to the armrest AR according to the modified example, in addition to the operational effects achieved by the armrest AR of the first embodiment described above, there is an operational effect that the armrest AR can be stopped and held at an appropriate position. In addition, such a stop-holding function is realized with a simple configuration in which a holding portion 80 is additionally formed at a predetermined position of the follower guide surface 52, so that there is almost no increase in the number of parts and work man-hours. Can be implemented without increasing.

(Second embodiment)
FIG. 11 is a plan view schematically illustrating the slide support unit 50 of the armrest AR according to the second embodiment. As illustrated in FIG. 11A, the armrest AR according to the second embodiment is obtained by changing the form of the follower guide surface 52 as compared with the first embodiment described above, and the console lid 14 ( The floor console 10) is an “automatic pull-in type” in which a positive (automatic) slide is developed in the backward direction. That is, the follower guide surfaces 52 and 52 are located on the rear side of the first guide member 42, and the oblique guide surfaces 56 that extend closer to the roller 60 toward the front of the console lid 14, 1 is composed of a parallel guide surface 54 located in front of the guide member 42 and extending in parallel with the sliding direction of the armrest AR (guide rails 46, 46). 54 are bent. That is, the oblique guide surface 56 extends so as to approach the direction opposite to the pressing direction by the torsion spring 62 as it goes to the front of the console lid 14.

  Thereby, when the armrest AR is moved to the foremost position, as illustrated in FIG. 11A, the rollers 60 and 60 are positioned on the parallel guide surfaces 54 of the corresponding driven guide surfaces 52 and 52. To do. At this time, the arm rest AR is slid although each leg 66, 66 of the torsion spring 62 is elastically deformed to the maximum in the direction approaching each other and presses the roller 60 toward the parallel guide surface 54 with a considerably strong force. Since the force to do is not expressed, it is held in the state stopped at the foremost position.

  Further, as illustrated in FIG. 11A, the bending point P between the parallel guide surface 54 and the oblique guide surface 56 is the roller 60 and the following guide surface 52 when the armrest AR is in the foremost position. The position is separated from the contact position by a predetermined interval. That is, the substantial effective length of the parallel guide surface 54 is the same as the distance to the bending point P, and when the roller 60 is located between them, the armrest AR is pushed backward or pulled forward. If it does not slide, it will stop at that position. That is, a region from the foremost position to the bending point P is a so-called “manual slide section MS”.

  On the other hand, when the armrest AR is pushed backward until it exceeds the manual slide section MS, the roller 60 passes the bending point P and moves from the parallel guide surface 54 to the oblique guide surface 56. As a result, the torsion spring 62 presses the rollers 60, 60 against the corresponding oblique guide surface 56, so that the armrest AR is positively moved backward even if the pushing backward is stopped as illustrated in FIG. Slide (automatically) and move to the last position. That is, a region from the bending point P to the rearmost position is a so-called “automatic slide section AS”.

  Note that the armrest AR stopped at the rearmost position is held at this position because the pressing force of the torsion spring 62 acts on the rollers 60 and 60 even in this state. Further, when moving to the foremost position, the rollers 60, 60 are transferred to the oblique guide surface 56 and the parallel guide surface 54 of the driven guide surface 52 by grasping the front side of the armrest AR and pulling it forward. In the process of movement, the torsion spring 62 is elastically deformed, and the armrest AR is allowed to slide.

  The armrest AR of the second embodiment configured as described above has the following operational effects. First, when the armrest AR located at the foremost position is slid to the rearmost position, the occupant only needs to push the distance of the manual slide section MS backward by his / her own force. In the automatic slide section AS, the armrest AR Will automatically slide backwards. Accordingly, since a support function for sliding the armrest AR backward is added, there is an advantage that the slide operability is greatly improved. In addition, the slide support unit 50 for realizing the support function is simply configured from a small number of parts (members) as in the first embodiment, and the number of parts and assembly man-hours are reduced, resulting in a significant increase in manufacturing cost. There is also an advantage of being reduced.

  Also in the armrest AR of the second embodiment, the backward movement of the armrest AR in the automatic slide section AS can be performed by changing the extending form of the oblique guide surface 56 in the follower guide surface 52 as in the first embodiment. It is possible to set various aspects. Further, as in the modified example of the first embodiment described above, it is possible to provide one or more recessed holding portions 80 along which the roller 60 can temporarily stop along the longitudinal direction of the follower guide surface 52. There is an effect that the armrest AR can be stopped and held at an appropriate position. In addition, such a stop-holding function is realized with a simple configuration in which a holding portion 80 is additionally formed at a predetermined position of the follower guide surface 52, so that there is almost no increase in the number of parts and work man-hours. Can be implemented without increasing.

(Third embodiment)
FIG. 12 is a plan view schematically illustrating the slide support unit 50 of the armrest AR according to the third embodiment. As illustrated in FIG. 12A, the armrest AR according to the third embodiment is obtained by further changing the extension mode of the follower guide surface 52, and with respect to the console lid 14 (floor console 10), It is an “automatic drawer / retraction type” in which positive (automatic) sliding in both the forward and backward directions is expressed. That is, the follower guide surfaces 52 and 52 are located on the rear side of the first guide member 42 and extend toward the front of the console lid 14 so as to approach the roller 60, and The second oblique guide surface 84 is provided on the front side of the first guide member 42 and is connected to the first oblique guide surface 82 and extends away from the roller 60 toward the front of the console lid 14. The oblique guide surfaces 82 and 84 are bent at the bending point P.

  When the armrest AR is moved to the rearmost position, as illustrated in FIG. 12A, each roller 60, 60 is moved to the first oblique guide surface 82 in the corresponding driven guide surface 52, 52. Located in. At this time, since the pressing force by the leg portions 66, 66 of the torsion spring 62 acts on the rollers 60, 60, the armrest AR is held in a state stopped at the rearmost position. Further, when the armrest AR is moved to the foremost position, as illustrated in FIG. 12B, the rollers 60 and 60 are provided with the second oblique guide surfaces 84 in the corresponding driven guide surfaces 52 and 52. Located in. At this time, since the pressing force by the leg portions 66 and 66 of the torsion spring 62 acts on the rollers 60 and 60, the armrest AR is held in a state stopped at the foremost position.

  The bending point P between the first oblique guide surface 82 and the second oblique guide surface 84 is a contact position between the roller 60 and the driven guide surface 52 when the armrest AR is at the rearmost position. The armrest AR is located in the middle of the contact position between the roller 60 and the follower guide surface 52 when the armrest AR is in the foremost position, that is, approximately at the center of the slide amount W. Accordingly, the rear half area from the rearmost position to the folding point P is referred to as “first automatic slide section AS1”, and the front half area from the folding point P to the forefront position is referred to as “second automatic slide section AS1”. AS2 ". Thereby, when each roller 60,60 is located in 1st slide area AS1, armrest AR always moves to the direction of the last position automatically, and each roller 60,60 is 2nd slide area AS2. When the armrest AR is in the position, the armrest AR always automatically moves in the direction of the foremost position.

  When moving the armrest AR in the rearmost position to the foremost position, the armrest AR is automatically slid to the forefront position after being pulled out by about half. Similarly, when the armrest AR at the foremost position is moved to the rearmost position, the armrest AR is automatically slid to the rearmost position when the armrest AR is pushed backward by about half.

  The armrest AR of the third embodiment configured as described above has the following operational effects. First, when the armrest AR at the rearmost position is slid to the foremost position, the occupant only has to pull the distance of the first automatic slide section AS1 forward by his / her own force, and the second automatic slide section AS2 In, the armrest AR automatically slides forward. Further, when the armrest AR at the foremost position is slid to the rearmost position, if the occupant pushes only the distance of the second automatic slide section AS2 backward by his / her own force, the first automatic slide section AS1 The armrest AR automatically slides backward. Therefore, a support function for sliding the armrest AR in both the front and rear directions is added, and there is an advantage that the slide operability is greatly improved. In addition, the slide support unit 50 for realizing the support function has a simple configuration like the first embodiment and the second embodiment described above, and the number of parts and assembly man-hours are reduced, resulting in a significant increase in manufacturing cost. There is also an advantage of being reduced.

  Further, the armrest AR of the third embodiment also extends from the first oblique guide surface 82 and / or the second oblique guide surface 84 on the follower guide surface 52, as in the first and second embodiments described above. By changing the present mode, it is possible to variously set the retract mode of the armrest AR in the first automatic slide section AS1 and / or the forward mode of the armrest AR in the second automatic slide section AS2. Further, similarly to the modified example of the first embodiment described above, the roller 60 is temporarily stopped along the longitudinal direction of the follower guide surface 52 (the first oblique guide surface 82 and the second oblique guide surface 84). If one or more possible recessed holding portions 80 are provided, there is an effect that the armrest AR can be stopped and held at an appropriate position.

  In each of the above-described embodiments, the guide guide surface 52 constituting the slide support unit 50, the roller 60, and the torsion spring 62 supporting the roller 60 are replaced by the first guide member 42 or the second guide member constituting the slide unit 40. Although the case where the guide member 44 is mounted is illustrated, the slide support unit 50 may be configured separately from the slide unit 40. Further, the first guide member 42 can be formed integrally with the lid body 20, and similarly, the second guide member 44 can be formed integrally with the rest base 32. That is, the guide rail 46 may be integrally formed with the lid body 20 and the guide groove 48 may be integrally formed with the rest base 32.

  Further, in each of the above-described embodiments, the torsion spring 62 is exemplified as the urging means, and the configuration in which the roller 60 is supported by the torsion spring 62 and the roller 60 is pressed against the driven guide surface 52 is exemplified. However, the biasing means is not limited to this torsion spring, and for example, a compression coil spring or a leaf spring can be implemented. In this case, the roller 60 may be slidably supported by another support means, and the support means may be urged by a compression coil spring, a leaf spring, or the like.

  The vehicle interior member to which the armrest of the present application is mounted is not limited to the console lid of the floor console exemplified in the above-described embodiments, but is a vehicle interior member (for example, a door panel or the like) disposed on the side of the seat. ), And arm rests and the like disposed in the center of a bench-type rear seat.

The slide mechanism of the armrest according to the present invention can be suitably implemented in an armrest that is slidably disposed on the upper surface of the vehicle interior member.
