Description

  The present invention relates to an armrest provided at an upper portion of a console box and configured to be slidable back and forth.

  The console box is installed, for example, between a driver's seat and a passenger seat of an automobile. The armrest provided on the upper part of the console box is configured to allow the passenger's arm to be put on it, and is configured to be swingable via a hinge so that the opening of the console box for storing small items can be opened and closed. Yes.

  The armrest can be slid forward and backward with respect to the occupant at the upper part of the console box so that the position where the occupant's arm is placed changes back and forth according to the seating position and physique of the occupant. In view of this, the armrest has a lower cover that is fixed to the upper portion of the console box and an upper cover that is slidably mounted on the upper side of the lower cover, and the upper cover on the side on which the occupant's arm is placed slides forward and backward relative to the lower cover. It is configured to let you.

  This type of armrest in the past stores a liner that can move in the left-right direction inside a pair of left and right side rails arranged on the lower cover, and the left and right edges of the slider fixed to the upper cover can be slid on this liner. As a means of engaging and providing a stable sliding resistance between the left and right edges of the slider and the liner, and a biasing force necessary to absorb the dimensional error between the parts, between the liner and the side rail. A spring member for directly urging the liner inward in the left-right direction is disposed (see Patent Document 1).

JP 2005-254881 A

  The conventional armrest configured in this way does not require an increase in the vertical dimension of the spring member itself in order to obtain a necessary elastic deformation stroke, and the overall vertical dimension of the armrest can be reduced.

  However, since this type of armrest is usually configured in a longitudinal direction corresponding to the console box, the armrest may be twisted in the left-right direction due to a pressing load generated by an occupant's arm or the like. The upper cover slides in a tilted state in the side rail.

  From this point of view, the armrest according to the above-described conventional technique remains inclined due to the twisting in the left-right direction described above even when a stable sliding resistance is provided between the left and right edges of the slider and the liner by the spring member. In the case of sliding, in combination with the surface contact state of the spring member in the side rail, the sliding resistance is further increased, resulting in an increase in the slide operation load. .

Therefore, in view of the problems in the conventional technology, the present invention can smoothly slide the upper cover with respect to the lower cover even when a pressing load that twists in the left-right direction is applied to the upper cover. The purpose is to provide an armrest constructed.

  An armrest according to the present invention is an armrest that can be slid forward and backward provided at an upper portion of a console box, and includes a lower cover provided at an upper portion of the console box and an upper cover that is slidable forward and backward with respect to the lower cover. Equipped with slide rails with a U-shaped cross section on both left and right sides of the upper cover so that they extend in the front-rear direction, and rollers pivotally attached to the lower cover so as to roll in both slide rails Three sets are arranged in the sliding direction, and among these three sets of rollers, the central roller in the front and rear sliding direction is brought into contact with the liner on the lower wall side of the slide rail, and is arranged at the front and rear in the front and rear sliding direction. The installed front and rear rollers contact the upper wall liner of the slide rail Each roller is configured to roll in the slide rail, and the lower cover is formed with a restriction piece inserted into the slide rail in a state adjacent to each of the three sets of rollers. To do.

  With such a configuration, the armrest in the present invention has a central roller lined to the lower wall side liner portion of the slide rail among the three sets of front and rear slide directions pivotally attached to the lower cover so as to roll in both slide rails. On the other hand, the front and rear rollers arranged in the front and rear in the sliding direction come into contact with each other at the upper wall side liner portion of the slide rail. Even when a pressing load that twists in the direction is applied, the three sets of rollers cancel each other in cooperation, and the upper cover can be smoothly slid in the front-rear direction with respect to the lower cover.

  Further, the armrest according to the present invention configured as described above is used when the pressing load that is twisted in the left-right direction by the occupant's arm or the like is relatively large when the regulating piece is stretched in the slide rail. Therefore, the torsional deformation can be suppressed, and the pressing force on the upper and lower wall liners of each roller is alleviated. From this surface, the sliding operation of the upper cover in the front-rear direction with respect to the lower cover can be performed smoothly. Can be done.

In addition, as an embodiment of the invention, the armrest according to the present invention uses a slider instead of the central roller, and attaches the slider to the lower cover so as to slide on the lower wall side liner portion of the slide rail. Is configured.

  With this configuration, the present invention adopts a line contact configuration by, for example, forming a contact portion with the lower wall side liner portion of the slider attached to the upper wall side liner portion in a sawtooth shape in section, for example, an occupant's arm Even if a pressing load that twists in the left-right direction is applied, the upper cover can be smoothly slid in the front-rear direction relative to the lower cover in cooperation with the front and rear rollers.

  The armrest according to the present invention is an armrest that can be slid forward and backward provided at the top of the console box, and a lower cover provided at the top of the console box and an upper cover that is slidably attached to the lower cover. A slide rail having a U-shaped cross section is arranged on both the left and right sides of the upper cover so as to extend in the front-rear direction, and a roller pivotally attached to the lower cover so as to roll in both slide rails. Three sets are arranged in the front and rear slide direction, and among these three sets of rollers, the center roller in the front and rear slide direction is brought into contact with the liner on the upper wall side of the slide rail, and the front and rear parts in the front and rear slide direction Slide the front and rear rollers on the lower rail of the slide rail. In this way, each roller is configured to roll in the slide rail, and the lower cover is formed with a regulation piece inserted into the slide rail in a state adjacent to each of the three sets of rollers. To do.

  With this configuration, the present invention is such that, among the three sets of rollers in the front-rear slide direction pivotally attached to the lower cover so as to roll in both slide rails, the rollers disposed in the front and rear in the slide direction are respectively lower walls of the slide rail. For example, an occupant's arm is in contact with the side liner portion by line contact, while the central roller disposed at the center in the sliding direction abuts by line contact at the upper wall side liner portion of the slide rail. Even if a pressing load that twists in the left-right direction is applied, the three sets of rollers cooperate to cancel each other, and the upper cover can be smoothly slid in the front-rear direction with respect to the lower cover.

  Further, the armrest according to the present invention configured as described above is used when the pressing load that is twisted in the left-right direction by the occupant's arm or the like is relatively large when the regulating piece is stretched in the slide rail. Therefore, the torsional deformation can be suppressed, and the pressing force on the upper and lower wall liners of each roller is alleviated. From this surface, the sliding operation of the upper cover in the front-rear direction with respect to the lower cover can be performed smoothly. Can be done.

  The armrest according to the present invention configured as described above has three sets of rollers in the front-rear sliding direction pivotally attached to the lower cover so as to roll in both slide rails, and the lower rail side liner portion or upper wall of the slide rail. Because it is in line contact with the side liner, even if a pressing load that twists in the left-right direction is applied by the occupant's arm, etc., the three rollers cancel each other out in cooperation. Thus, the upper cover can be smoothly slid in the front-rear direction with respect to the lower cover.

  In addition, the armrest according to the present invention configured as described above is used when the pressing load that is twisted in the left-right direction by the occupant's arm or the like is relatively large due to the restriction piece stretching in the slide rail. Therefore, the torsional deformation can be suppressed, and the pressing force on the upper and lower wall liners of each roller is alleviated.

  The armrest according to the present invention is configured so that the upper cover can slide smoothly with respect to the lower cover even when a pressing load that twists in the left-right direction is applied to the upper cover.

  Next, the Example concerning the armrest of this invention is described using figures.

  As shown in FIG. 1, an armrest 1 according to an embodiment of the present invention is provided, for example, on an upper part of a console box 2 installed between a driver's seat and a passenger seat of an automobile. The upper opening of the console box 2 is opened and closed.

  As shown in FIG. 2, the armrest 1 has a lower cover 4 provided on the upper portion of the console box 2 and a later-described configuration with respect to the lower cover 4 in order to open and close the upper opening of the console box 2. And an upper cover 5 slidably mounted in the front-rear direction.

  As shown in FIG. 2, a hinge 3 is installed at the rear end portion of the lower cover 4, and an armrest 1 is attached to the console box 2 so as to be swingable in the front-rear direction of the vehicle. In addition, a base member 6 formed in a substantially U-shape in front view is attached to the central portion of the lower cover 4 in the longitudinal direction (front-rear direction of the vehicle). The base member 6 has left and right side standing walls 6a and 6b facing each other in the left and right direction of the vehicle, and the inward wall surfaces of the left and right side standing walls 6a and 6b are as shown in FIG. Three sets of cylindrical rollers 7, 8, 9 are arranged in parallel in the longitudinal direction of the vehicle.

  Each roller 7, 8, 9 is inserted into cylindrical pivots 6 c, 6 d, 6 e formed on the inward wall surfaces of the left and right side standing walls 6 a, 6 b, respectively, and has large diameter heads 7 a, 8 a, 9 a. Mounting shafts 7b, 8b, and 9b, respectively, are inserted into the pivot shafts 6c, 6d, and 6e, and screws 6-1 are screwed into the mounting shafts 7b, 8b, and 9b from the outward wall surfaces of the left and right standing walls 6a and 6b. By wearing, it mounts | worn so that it can rotate centering | focusing on each pivot 6c, 6d, 6e with respect to right-and-left both-side standing wall 6a, 6b.

  The upper cover 5 is configured with a slider member 10 attached to the lower surface thereof. A pair of slide rails 11 are provided at both left and right ends of the vehicle in the slider member 10 so as to extend in the front-rear direction of the vehicle. The slide rail 11 is configured by integrally forming a back wall 11a and an upper wall liner portion 11b and a lower wall liner portion 11c formed on both upper and lower side portions of the back wall 11a in a U-shaped cross section.

  Between the upper wall side liner portion 11b and the lower wall side liner portion 11c, three sets of rollers 7, 8, 9 are respectively arranged so as to be able to roll, and the three sets of rollers 7, 8, 9 are arranged. By rolling in the slide rail 11, the upper cover 5 together with the slider member 10 can slide in the vehicle front-rear direction with respect to the lower cover 4.

  Among the three sets of rollers 7, 8, 9, the central roller 8 disposed at the central portion of the base member 6 in the vehicle front-rear direction is a lower wall of the slide rail 11 as shown in FIGS. 6 and 7. While abutting on the side liner part 11c side by line contact, the upper wall side liner part 11b is separated and opposed with an appropriate gap. Of the three sets of rollers 7, 8, and 9, the rear roller 7 disposed on the rear side of the vehicle in the base member 6 is an upper wall side of the slide rail 11 as shown in FIGS. 4 and 5. While abutting on the liner portion 11b side by line contact, the lower wall side liner portion 11c is separated and opposed with an appropriate gap. Similarly, of the three sets of rollers 7, 8, 9, the front side roller 9 disposed on the front side of the vehicle in the base member 6 is in line contact with the upper wall side liner portion 11 b side of the slide rail 11. And is opposed to the lower wall side liner portion 11c with an appropriate gap.

  Further, as shown in FIG. 10, in the state where the front side roller 9 (and the rear side roller 7) are adjacent to the left and right standing walls 6 a and 6 b of the base member 6 at the front and rear portions of the vehicle, A pair of downward restricting pieces 12 to be formed is formed. Of the upper and lower tip portions of the downward regulating piece 12, the upper tip portion 12a contacts the upper wall side liner portion 11b and the lower tip portion 12b is separated from the lower wall side liner portion 11c (see FIG. 11). ). The spacing dimension is slightly smaller than the spacing dimension with the lower wall side liner portion 11c of the front side roller 9 (and the rear side roller 7).

  Therefore, if a pressing load is applied to the upper cover 5 by an occupant's arm or the like, the lower end portion 12b of the downward regulating piece 12 comes into contact with the lower wall side liner portion 11c, and the downward regulating piece 12 slides. By stretching between the upper wall side liner portion 11b and the lower wall side liner portion 11c of the rail 11, the gap between the front side roller 9 (and the rear side roller 7) and the lower wall side liner portion 11c is slight. Is held. As a result, when the upper cover 5 is slid in the vehicle front-rear direction with respect to the lower cover 4, the lower tip 12b of the downward regulating piece 12 slides in the slide rail 11 together with the upper tip 12a. However, the tip portion is formed in a sharp shape such as a triangular shape, and the line contact is maintained on the lower wall side liner portion 11c or the upper wall side liner portion 11b, so that the upper cover 5 can be smoothly moved. I have to.

  Similarly, as shown in FIG. 11, the downward restricting pieces 13 constituting the restricting pieces are formed on the left and right standing walls 6 a and 6 b of the base member 6 at the front and rear parts of the vehicle at the center roller 8. Of the upper and lower tip portions of the upward restriction piece 13, the lower tip portion 13b contacts the upper wall side liner portion 11b, and the upper tip portion 13a is separated from the upper wall side liner portion 11b. Yes. The spacing dimension is slightly larger than the spacing dimension with respect to the upper wall side liner portion 11b of the central roller 8.

  Therefore, if a pressing load is applied to the upper cover 5 by an occupant's arm or the like, the tip of the upward regulating piece 13 comes into contact with the upper wall side liner portion 11b, and the upward regulating piece 13 is moved to the slide rail 11 By stretching the space between the upper wall side liner portion 11b and the lower side liner portion 11c, the gap with the upper wall side liner portion 11b of the center roller 8 is slightly maintained. As a result, when the upper cover 5 is slid in the front-rear direction of the vehicle with respect to the lower cover 4, the tip of the upward restriction piece 13 slides together with the downward restriction piece 12. Is formed in a sharp shape like a triangular shape, for example, and the line contact is held on the upper wall side liner portion 11b to make the upper cover 5 slide smoothly.

  In one embodiment of the present invention configured as described above, three sets of rollers 7, 8, which are pivotally attached to the base member 6 of the lower cover 4 so as to roll in both slide rails 11, 9, the central roller 8 is in contact with the lower wall side liner portion 11 c of the slide rail 11 by line contact, while the front roller 9 and the rear roller 7 disposed in the front and rear of the sliding direction slide. Since the upper wall side liner portion 11b of the rail 11 abuts by line contact, the upper cover 5 is applied to the lower cover 4 even if a pressing load that twists in the left-right direction is applied by an occupant's arm or the like. Can be smoothly slid back and forth.

  Further, in the first embodiment, when a pressing load that is twisted in the left-right direction by an occupant's arm or the like is large, the lower front end portion 12b of the downward regulating piece 12 abuts on the lower wall side liner portion 11c. Or the upper end portion 13a of the upward restricting piece 13 abuts on the upper wall side liner portion 11b, and the downward restricting piece 12b or the upward restricting piece 13 is pulled in the slide rail 11, whereby the upper cover 5 is twisted. The twisting deformation can be suppressed, and the pressing force to the upper and lower wall liner portions 11b and 11c of the rollers 7, 8, and 9 is alleviated. From this surface, the upper cover 5 with respect to the lower cover 4 is also reduced. The sliding operation in the front-rear direction can be performed smoothly.

  FIG. 12 shows a modification to the above embodiment. According to FIG. 12, a slider 14 is used instead of the central roller 8. The slider 14 is configured to be attached to the base member 6 so as to slide on the lower wall side liner portion 11c of the slide rail 11. A contact portion of the slider 14 with the lower wall side liner portion 11c is formed in, for example, a sawtooth cross section.

  As a result, the slider 14 has a line contact configuration with respect to the lower wall side liner portion 11c. For example, it is assumed that a pressing load that twists in the left-right direction by an occupant's arm or the like is applied. In addition, in cooperation with the front and rear rollers, the upper cover can be smoothly slid in the front-rear direction with respect to the lower cover.

  FIG. 13 shows another embodiment according to the present invention. According to FIG. 13, among the three sets of rollers 7, 8, 9, the central roller 8 in the front-rear slide direction is brought into contact with the upper wall side liner portion 11 b of the slide rail 11 and the rear-side roller in the front-rear slide direction 7 and the front roller 9 are in contact with the lower wall side liner portion 11c of the slide rail 11 so that the rollers 7, 8, 9 roll in the slide rail 11. Further, the regulating piece is configured such that the tip end portion is separated from the upper wall side liner portion 11b in the state adjacent to the rear side roller 7 and the front side roller 9 on the lower wall side liner portion 11c of the slide rail 11. The upward restriction piece 13 is formed, and the restriction piece is also configured so that the tip end portion is separated from the lower wall liner portion 11c in the state adjacent to the central roller 8 on the upper wall side liner portion 11b of the slide rail 11. A downward regulating piece 13 is formed and configured. The other configurations are the same as those in the above embodiment.

  With this configuration, in another embodiment, the rollers 7, 8, 9 in the front / rear slide direction are pivotally attached to the lower cover 4 so as to roll in the slide rails 11, and arranged in the front / rear direction of the slide direction. The rear roller 7 and the front roller 9 are in contact with the lower wall side liner 11c of the slide rail 11 by line contact, while the central roller 8 disposed in the center of the slide direction is the slide rail. Since the upper wall side liner portion 11b is in contact with the upper wall side 11b by line contact, the upper cover 5 is attached to the lower cover 4 even if a pressing load that twists in the left-right direction is applied by the occupant's arm or the like. It can be smoothly slid back and forth.

  Further, in the embodiment shown in FIG. 13, when a pressing load that is twisted in the left-right direction by an occupant's arm or the like is large, the tip of the downward regulating piece 12 abuts on the lower wall side liner portion 11c or is directed upward. By the restriction piece 13 coming into contact with the upper wall side liner portion 11b, the downward restriction piece 12 and the upward restriction piece 13 are stretched between the upper wall side liner portion 11b and the lower wall side liner portion 11c of the slide rail 11. The torsional deformation can be suppressed, and the pressing force to the upper and lower wall liner portions 11b, 11c of the rollers 7, 8, 9 is alleviated. From this surface as well, the upper with respect to the lower cover 4 can be reduced. The sliding movement of the cover 5 in the front-rear direction can be performed smoothly.

  The present invention is provided at the upper portion of the console box by configuring the upper cover so that it can slide smoothly with respect to the lower cover even when a pressing load that is twisted in the left-right direction is applied to the upper cover.
