Description

TECHNICAL FIELD The present invention relates to an improvement of a vehicle armrest that also serves as a lid for a storage section in a center console box of a vehicle.

2. Description of the Related Art A conventional armrest for a vehicle is disclosed in Patent Document 1, for example. The vehicle armrest described in Patent Literature 1 is attached to the upper side of the mount so as to be movable in the longitudinal direction of the vehicle. This vehicle armrest has a lock plate fixed to the bottom, a lock bolt arranged below the lock plate with its head upward, and a handle for rotating the lock bolt on the back side of the mount. The lock bolt has a threaded portion that penetrates the inside of the mounting base, and moves up and down by rotating the handle. The lock plate has a slit extending in the longitudinal direction of the vehicle, and the slit is formed with locking holes at predetermined intervals for engaging and disengaging the heads of the lock bolts.

When the lock bolt is loosened by rotating the handle, the vehicle armrest moves downward to disengage the head from the locking hole of the lock plate, thereby allowing the armrest to move in the longitudinal direction of the vehicle with respect to the mount. Thus, after the position of the vehicle armrest is adjusted in the longitudinal direction of the vehicle, by tightening the lock bolt with the handle, the head of the armrest is locked in the corresponding locking hole to maintain the adjusted position.

Japanese Utility Model Laid-Open No. 63-159336

However, since the conventional vehicle armrest as described above is locked at the adjusted position, it is not suitable for a situation in which the position must be adjusted frequently. Therefore, the vehicle armrest described above can always adjust the position in the longitudinal direction of the vehicle by leaving the lock bolt loosened by the handle or by removing the handle and the lock bolt. However, in the vehicle armrest described above, if the lock bolt is left loose, the handle may fall off, and if the handle and the lock bolt are removed, these parts may be lost.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle armrest that enables stepwise and stepless position adjustment, prevents the loss of parts, and improves convenience.

A vehicle armrest according to the present invention is a vehicle armrest that also serves as a lid for a storage section in a center console box of a vehicle, and includes an opening/closing body that opens and closes the upper side of the storage section. The opening/closing body includes an inner base part rotatably connected to the box body, an outer lid part connected to the base part so as to be able to move forward and backward, and a pin-shaped locking member mounted from the inside of the base part. In the vehicle armrest, the base portion has a fixing hole through which the lock member is inserted in one side in the left-right direction, and a storage hole in which the lock member is inserted through, on the other side in the left-right direction. In addition, it is characterized in that the lid portion is allowed to move forward and backward while the lock member is attached to the storage hole.

In the above-described vehicle armrest, the lid portion adjusted in the longitudinal direction of the vehicle is locked by engaging the tip portion of the locking member penetrating the fixing hole at a predetermined forward/backward position of the lid portion with the positioning portion. That is, it is possible to adjust the position of the lid in stages. In addition, in the vehicle armrest described above, the same lock member is inserted into the storage hole so that the lid portion can be advanced and retracted, and the position can be adjusted steplessly, and the possibility of losing the lock member can be eliminated.

By adopting the above configuration, the vehicle armrest according to the present invention enables stepwise position adjustment and stepless position adjustment, prevents loss of parts, and improves convenience.

<First embodiment>
An embodiment of a vehicle armrest according to the present invention will be described below with reference to the drawings. In the following description, the vertical, front, rear, left, and right directions and positions are based on the orientation of the vehicle. Further, the armrest for a vehicle according to the present invention also serves as a lid for the storage section in the center console box of the vehicle, and has a configuration for opening and closing the storage section and a configuration for adjusting the position in the front-rear direction in addition to the original armrest portion.

That is, as shown in FIG. 1, the vehicle armrest 1 includes an opening/closing body 2 for opening and closing the upper side of the storage portion A of the box body B, a switch knob 3 for opening the opening/closing body 2, and an operation transmission mechanism 4 for opening the opening/closing body 2 in conjunction with the operation of the switch knob 3. The switch knob 3 is arranged on the front side of the opening/closing body 2 in the box body B.

The illustrated box main body B has a container holder H1 on the front right side of the opening/closing body 2, and has a parking brake operation lever P on the front left side. The container holder H1 is generally called a drink holder or cup holder, and holds PET bottles and cups. 1, the front portion of the box body B is omitted.

2 and 3, the opening/closing body 2 includes an inner base portion 5 rotatably connected to the box body B, an outer lid portion 6 connected to the base portion 5 so as to be able to advance and retreat in the longitudinal direction, and a pin-shaped lock member 10 attached from the inside of the base portion 5.

In the vehicle armrest 1, the base portion 5 has a fixing hole 11 on one side in the left-right direction (the left side in FIG. 2A) for penetrating the lock member 10, and a storage hole 12 on the other side in the left-right direction for penetrating the lock member 10. On the other hand, the lid portion 6 is provided with a positioning portion 13 that restricts the forward/backward movement of the lid portion 6 by engaging with the tip portion of the locking member 10 penetrating the fixing hole 11 at a predetermined forward/backward position. The above-described vehicle armrest 1 restricts forward/backward movement of the lid portion 6 with the lock member 10 attached to the fixing hole 11, and allows the forward/backward movement of the lid portion 6 with the lock member 10 removed from the fixing hole 11 and attached to the storage hole 12.

The base part 5 of the opening/closing body 2 has a size that closes the upper opening of the storage part A, is connected to the box body B at the rear end via a hinge (not shown), and is biased in the opening direction (upward) by an elastic body such as a torsion spring modified to the hinge shaft. At this time, the urging force of the base 5 may be a force such that at least the front end portion of the opening/closing body 2 is lifted when the locked state of the opening/closing body 2 is released.

As shown in FIG. 2A, the lid portion 6 of the opening/closing body 2 is movable in the front-rear direction with respect to the base 8 by means of left and right guides 7, 7 provided between the lid portion 5 and the base portion 5 and a rack 9 meshing with the pinion 8 arranged on the base 5 side. The lid portion 6 can maintain its adjusted position by appropriate frictional resistance at the contact portions of both the guides 7, the pinion 8 and the rack 9, and can be moved freely by a force exceeding the frictional resistance.

The opening/closing body 2 is provided with left and right spaces 14L and 14R on both sides in the left-right direction between the base portion 5 and the lid portion 6 shown in FIG. In addition, as shown in FIG. 3C, the opening/closing body 2 has a positioning portion 13 for regulating the position of the lid portion 6 in one space 14L, and the other space 14R, as shown in FIG.

As shown in FIG. 2B, the lock member 10 is a trim clip having a threaded portion 10B provided on the axis of the main body portion 10A and a distal end portion 10C that expands and deforms in the radial direction when the threaded portion 10B is screwed. The positioning portions 13 are holes through which the front end portion 10C of the locking member 10 passes, and are formed at a plurality of positions in the front-rear direction on the inner wall 6A of the lid portion 6. As shown in FIG. The holes as the positioning portions 13 are arranged at least at two locations corresponding to the forward (frontmost) position and the retracted (rearmost) position of the lid portion 6, and more preferably at two or more locations including intermediate positions between the forward and retracted positions.

The locking member 10 is attached to either the fixing hole 11 or the storage hole 12 . 2A, the lock member 10 is passed through the fixing hole 11 or the positioning portion 13, and the tip portion 10B is expanded and deformed by operating the screw portion 10B.

In addition, the lock member 10 is removed from the fixing hole 11 and the positioning portion 13 to allow the advance and retraction of the lid portion 6. At this time, as indicated by the solid line in FIG.

In the opening/closing body 2, the base portion 5 has recesses 15L and 15R on both sides in the left-right direction on the inner surface thereof, and as shown in FIG.

Further, in the opening/closing body 2, the depth dimension DL of one recessed portion 15L is made smaller than the depth dimension DR of the other recessed portion 15R. Further, in the opening/closing body 2, both recesses 15L and 15R form short grooves extending in the front-rear direction.

4 and 5, the motion transmission mechanism 4 includes a switch shaft 16 that is guided in the vertical direction and biased upward, a locking member 17 that is guided in the front-rear direction and biased rearward, and a cam mechanism 18 that converts downward movement of the switch shaft 16 into forward movement of the locking member 17.

The switch knob 3 is fixed to the upper end of the switch shaft 16, and is arranged on the upper surface of the box body B on the front side of the front end of the opening/closing body 2 with the lid 6 moved to the front end, that is, arranged at a fixed position with respect to the retractable lid 6. As a result, the switch knob 13 can be operated without being influenced by the adjustment position of the driver's seat in the longitudinal direction.

The switch shaft 16 is guided vertically by a vertical guide portion 51 formed in a housing 50, which is the internal structure of the box body B, and has a cam surface 18A that constitutes the cam mechanism 18 in its intermediate portion. This cam surface 18A is a downward cam surface having an upward slope in the forward direction. The switch shaft 16 is biased upward by a vertical spring 19 interposed at its lower end.

The locking member 17 is guided in the front-rear direction by a groove-shaped guide portion 52 formed in the housing 50, and has a cam surface 18B that constitutes the cam mechanism 18 together with the cam surface 18A. This cam surface 18B is an upward cam surface having a downward slope in the rearward direction. The locking member 17 is biased rearward by a horizontal spring 20 arranged on the front side.

The switch shaft 16 and the locking member 17 are combined with each other by setting their respective shapes so that the cam surfaces 18A and 18B are in contact with each other, and in particular, the peripheral portions of the cam surfaces 8A and 18B do not interfere with their reciprocating movements. These structures are not particularly limited, but as an example, the switch shaft 16 is a hollow body that is open in the front-rear direction, the locking member 17 is passed through the hollow part, and the cam surfaces 18A and 18B are arranged at the intersections of each other.

In addition, as shown in FIGS. 3B and 5, the motion transmission mechanism 4 of this embodiment has a locking projection 17A at the rear end of the locking member 17, and a locking recess 5A at the front end of the base portion 5. The engaging projection 17A protrudes into the storage portion A and has an upwardly inclined surface that slopes downward in the rearward direction as a surface for pushing the engaging member 17 when the opening/closing body 2 is closed.

Here, the box main body B has a movable range of the operating lever P of the parking brake, and a second container holder H2 that is opened and closed in accordance with the forward and backward movement of the lid portion 6 in the closed position of the opening/closing body 2. As shown in FIG.

For this reason, as shown in FIG. 5, the locking member 17 has a crank shape that avoids the second container holder H2 in plan view, and has a rib-like reinforcing portion 17F at the corner portion of the crank shape. Thus, the vehicle armrest 1 arranges the power transmission mechanism 4 in a narrow space of the box body B and also arranges the switch knob 3 at a fixed position away from the opening/closing body 2 to ensure the opening/closing operation of the opening/closing body 2.例文帳に追加

Furthermore, as shown in FIG. 6, the motion transmission mechanism 4 of this embodiment has locking claws 23 shown in FIG. The switch knob 3 is provided with locking holes 25 shown in FIG.

As shown in FIG. 6A, the motion transmission mechanism is provided with projecting left-right restricting portions 21 that abut on the switch knob 3 on the left and right sides of the upper end of the switch shaft 16, and as shown in FIG. As a result, the motion transmission mechanism 4 prevents the switch knob 3 and the switch shaft 16 from rattling in the front, rear, left, and right directions, and maintains smooth motion over a long period of time.

The vehicle armrest 1 having the above configuration can adjust the position of the lid portion 6 of the opening/closing body 2 between the forward position shown in FIG. 1(A) and the retracted position shown in FIG. 2(B). At this time, the position of the lid portion 6 can be adjusted steplessly by attaching the lock member 10 to the storage hole 12 as described above. In addition, by attaching a lock member 10 to the fixing hole 11, the lid portion 6 can be adjusted in stages and restrained at the adjusted position.

When the switch knob 3 of the vehicle armrest 1 is pushed, the operation transmission mechanism 4 functions to rotate the opening/closing member 2 upward to open the storage portion A, as shown in FIG. 1(C). Specifically, when the switch knob 3 is pushed, the switch shaft 16 descends against the vertical spring 19 and the cam surface 18A presses the cam surface 18B of the locking member 17 . As a result, the locking member 17 moves forward against the horizontal spring 20 , and the locking convex portion 17</b>A separates from the locking concave portion 5</b>A of the base portion 5 . At this time, since the opening/closing body 2 is urged upward by an elastic body (not shown), the locked state is released by the detachment of the locking projection 17A, and the front part is lifted up to open the storage part A. As shown in FIG.

Further, in the vehicle armrest 1, when the opening/closing body 2 is rotated downward, the lower end of the locking recess 5A of the base portion 5 presses the inclined surface of the locking projection 17A, pushing the locking member 17 forward against the horizontal spring 20. Then, when the opening/closing body 2 is pushed until the lower end of the locking recess 5A exceeds the tip of the locking projection 17A, the locking member 17 is pushed back backward by the horizontal spring 20, and the locking projection 17A protruding into the storage portion A is locked to the locking recess 5A to enter the locked state.

The vehicle armrest 1 includes an inner base portion 5, an outer lid portion 6, and a lock member 10 as an opening/closing body 2 that opens and closes the upper side of the storage portion A. The base portion 5 has a fixing hole 11 and a storage hole 12, and the lid portion 6 includes a positioning portion 13 that engages with the tip portion of the locking member 10 passing through the fixing hole 11 to restrict the forward and backward movement of the lid portion 6. As a result, the vehicle armrest 1 can be adjusted stepwise and steplessly, and the parts, that is, the lock member 10 can be prevented from being lost, thereby improving convenience. Moreover, the vehicle armrest 1 described above can open and close the storage section A by rotating the opening/closing body 2 even when the lid section 6 is adjusted to any position within the forward/backward movement range.

Further, the vehicle armrest 1 is provided with left and right spaces 14L and 14R on both sides in the left-right direction between the base portion 5 and the lid portion 6, into which the tip portion of the locking member 10 passing through the fixing hole 11 or the storage hole 12 enters. This will
When the lock member 10 is attached to the storage hole 12 , the vehicle armrest 1 can move the lid portion 6 back and forth without causing the lock member 10 and the lid portion 6 to interfere with each other.

Further, in the vehicle armrest 1 described above, the lock member 10 is a trim clip, and the positioning portion 13 is a hole through which the tip portion 10C of the lock member 10 is passed. As a result, the vehicle armrest 1 can be mounted with the locking member 10 with a simple operation, and can reliably restrain the lid portion 6 whose position is adjusted with respect to the base portion 5, while having a relatively simple structure.

Further, in the vehicle armrest 1, the fixing holes 11 and the storage holes 12 are arranged in the bottoms of the concave portions 15L and 15R provided on the inner surface of the base portion 5. Therefore, it is possible to prevent the locking member 10 fitted in the fixing holes 11 or the storage holes 12 from protruding into the storage portion A. That is, it is possible to prevent the head portion of the lock member 10 from interfering with the articles stored in the storage portion A.

Further, in the vehicle armrest 1 described above, the depth dimension D of the recess 15L having the fixing hole 11 is smaller than the depth dimension DR of the recess 15R having the storage hole 12 . As a result, the vehicle armrest 1 can sufficiently secure a space 14R into which the lock member 10 mounted in the storage hole 12 enters, and can secure a storage space for the lock member 10 in a vertically narrow space. Further, by making the depth dimensions of both the recesses 15L and 15R different, it is possible to easily distinguish between the fixing use and the storage use.

Further, in the vehicle armrest 1, the concave portions 15L and 15R are formed in the shape of short grooves extending in the front-rear direction, so that when the lock member 10 is attached and detached by picking it up with fingers, a space is secured around the lock member 10, and the attachment and detachment operation can be easily performed.

In the above-described embodiment, the rear end of the base portion 5 of the opening/closing body 2 is rotatably connected to the box body B, but a configuration in which the side portion of the base portion 5 is rotatably connected to the box body B can also be adopted. In this case, the opening/closing body 2 is configured such that an outer lid portion 6 is combined with an inner base portion 5 so as to be movable in the longitudinal direction, and rotates in the lateral direction of the vehicle to open and close the storage portion A.

The configuration of the vehicle armrest according to the present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the gist of the present invention. For example, a bolt can be used as the pin-shaped locking member. In this case, it is possible to form an internal thread in the fixing hole and the storage hole, or use nuts as the positioning portion.
