PROBLEM TO BE SOLVED: To provide a rotary long grip which can assure a storage space for a spring and a damper.SOLUTION: Each of hinge mechanisms 30, which are provided at both ends of a grip body 20, comprises a spring 32 and a damper 33. Consequently, a spring torque can be weakened and a size of the spring 32 can be reduced, and further, a damper torque can be weakened and a size of the damper 33 can be reduced as compared with the case (conventional one) that a spring is provided at only one end of the grip body 20 and a damper is provided at only the other end thereof. Therefore, in even a long grip, a storage for the spring 32 and the damper 33 can be assured. In addition, the damper 33 is located on an inner diameter side of a wound portion 32a of the spring 32, and is advantageous for a storage space for the damper 33.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a rotary long grip disposed on a vehicle ceiling or the like.

  Japanese Patent Laying-Open No. 2010-195161 discloses a rotary assist grip disposed on the ceiling of a passenger compartment. In the above publication, as shown in FIG. 6, the spring 3 is disposed at one end of the grip body 2, and the damper 4 is disposed at the other end of the grip body 2. The damper 4 is a rotary damper, and includes a damper inner 4a and a damper outer 4b that is positioned on the outer diameter side of the damper inner 4a and is rotatable relative to the damper inner 4a. The damper inner 4a is provided with a non-circular boss portion 4a1, and the ridge portion 4b1 is provided on the outer peripheral portion of the damper outer 4b.

However, the conventional rotary assist grip has the following problems.
By extending the length of the grip body 2 (long grip with a mounting pitch of 200 mm or more) and extending it in the vehicle width direction at the rear end of the vehicle compartment ceiling, the back door was opened when used outdoors, etc. Sometimes there is a need to be able to wear a lot of costumes. If the length of the grip body 2 is increased in order to satisfy this need, the grip body 2 becomes a heavy object. Therefore, when the spring 3 is disposed at one end of the grip body 2 and the damper 4 is disposed at the other end, the torque of the spring 3 and the damper 4 must be increased, and the space for storing the spring 3 and the damper 4 is required. It is difficult to ensure. Further, since the spring 3 is disposed only at one end portion of the grip body 2 and the damper 4 is disposed only at the other end portion of the grip body 2, the grip body 2 may be inclined and difficult to operate.

The long grip 10 is arranged, for example, extending in the vehicle width direction at the rear end of the passenger compartment ceiling R. When the back door (not shown) is opened during outdoor use, a relatively large number of costumes are hung. It is supposed to be. However, the arrangement position of the long grip 10 is not limited to the rear end portion of the vehicle interior ceiling R, and may be the vehicle width direction end portion of the vehicle interior ceiling R or the like.

As shown in FIG. 1, the grip body 20 is configured by connecting a plurality of components (two components in FIG. 1) in the grip longitudinal direction L, and a core material 21 is provided inside to improve rigidity. It is desirable that As shown in FIGS. 3 and 4, when the grip body 20 is in the retracted position 20a (when it is in the state of the solid line in FIGS. 3 and 4), the grip body 20 is entirely within the recess R1 provided in the passenger compartment ceiling R (almost). (Including the whole) is stored and does not protrude into the passenger compartment and is in the use position 20b (when it is in the state of the two-dot chain line in FIGS. 3 and 4), the vehicle is largely out of the recess R1. It protrudes into the room. As shown in FIG. 1, the grip body 20 includes attachment portions 22 that extend in opposite directions to the grip longitudinal direction L at both ends in the grip longitudinal direction L.

The hinge mechanisms 30 are provided at both ends of the grip body 20 in the longitudinal direction L, respectively. The hinge mechanism 30 is provided on each of the attachment portions 22 of the grip body 20. Each hinge mechanism 30 brakes the hinge member 31 fixed to the vehicle body, the spring 32 that urges the grip body 20 to rotate relative to the hinge member 31, and the rotation of the grip body 20 relative to the hinge member 31. And a damper 33 to be applied.

As shown in FIG. 3, the hinge member 31 is fixedly attached to the passenger compartment ceiling R using bolts 31a, nuts 31b, and the like. It is desirable that a cap 31c for hiding the head of the bolt 31a is attached to the hinge member 31. The hinge member 31 may be fixedly attached to the passenger compartment ceiling R using a clip (not shown) instead of the bolt 31a and the nut 31b.

As shown in FIG. 1, the hinge member 31 includes a pair of foot portions 31 d and 31 d provided at intervals in the grip longitudinal direction L. The hinge member 31 rotatably supports the grip body 20 using a round pin 31e having a circular cross section at a pair of foot portions 31d and 31d.

The spring 32 is a torsion spring, which is a coiled winding portion 32a, one end portion 32b connected to one axial end portion of the winding portion 32a and hooked on the hinge member 31, and the other axial end portion of the winding portion 32a. And the other end 32c hooked to the grip body 20. The spring 32 constantly urges the grip body 20 to rotate relative to the hinge member 31 from the use position 20b to the storage position 20a.

The damper 33 is a rotation type oil damper. As shown in FIG. 2, the outer diameter of the damper 33 is smaller than the inner diameter of the winding portion 32a of the spring 32, and the damper 33 is disposed in a space on the inner diameter side of the winding portion 32a. The damper 33 includes a damper main body 34 and a damper case 37 in which the damper main body 34 is accommodated.

By inserting the non-circular pin 38 having the same shape into the non-circular hole 37d and the non-circular hole 23 having the same shape provided in the grip body 20, the damper case 37 cannot be rotated relative to the grip body 20. Yes.

Next, the operation and effect of the embodiment of the present invention will be described.
Each hinge mechanism 30, 30 provided at both ends of the grip body 20 includes a spring 32 and a damper 33. Therefore, compared with the case where the spring 32 is provided only at one end of the grip body 20 and the damper 33 is provided only at the other end (conventional), the spring torque can be reduced and the spring can be downsized, and the damper torque can be reduced. Can be downsized. Therefore, even if it is a long grip, the storage space of the spring 32 and the damper 33 is securable.

Since the damper 33 is disposed on the inner diameter side of the winding portion 32a of the spring 32, the damper 33 is stored compared to the case where the damper 33 and the spring are disposed on the same axis line (at different positions in the axial direction). Space is advantageous.

Therefore, a conventional damper can be used for the damper main body 34, which is advantageous in terms of cost compared to the case where the damper main body 34 is newly designed and manufactured.
Further, the damper outer 36 is accommodated in the damper case 37 so as not to rotate relative to the damper case 37, and the damper case 37 is made non-rotatable relative to the grip body 20 by using the non-circular pin 38. Therefore, even when the damper 33 is disposed on the inner diameter side of the spring 32 and the protrusion 36a of the damper outer 36 cannot be directly engaged with the grip body 20, the damper outer 36 and the grip body 20 are The damper case 37 and the non-circular pin 38 can be engaged with each other.

Since the long grip 10 is a rotary long grip, the grip body 20 can be prevented from protruding into the vehicle compartment when the long grip 10 is not used, unlike the case where the long grip 10 cannot be rotated. It is possible to suppress the hindrance to securing the rear view when the vehicle is traveling.

  Each hinge mechanism 30, 30 provided at both ends of the grip body 20 includes a spring 32 and a damper 33. Therefore, compared with the case where the spring 32 is provided only at one end of the grip body 20 and the damper 33 is provided only at the other end (conventional), the grip body 20 can be prevented from being tilted by the spring torque and the damper torque. It can be rotated and stored stably.
