Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assist grip for gripping and supporting the body of an occupant when he / she rides in a vehicle such as a vehicle, a ship or an airplane.

[0002]

2. Description of the Related Art Conventionally, as an assist grip for a vehicle, for example, one shown in FIG. 7 has been known. The assist grip 51 includes a base 52 and a grip body 53. The base 52 is fixed to a vehicle ceiling 55 by bolts 54. The grip body 53 is a portion to be gripped by an occupant, and both ends of the grip body 53 are supported by the shaft 56.
It is rotatably attached to No. 2. A torsion coil spring 57 is wound around the shaft 56, one end of which is locked to the base 52 and the other end of which is locked to the grip body 53.
With this torsion coil spring 57, the assist grip 5
When No. 1 is not used, the grip body 53 is rotationally biased to the position (storage position) shown by the solid line in FIG. 7.

In the prior art thus constructed, when the passenger uses the assist grip 51, the grip main body 53 in the retracted position is twisted by the torsion coil spring 57.
7 against the elastic force of., Causing up to the use position shown by the chain double-dashed line in FIG. Further, when the use of the assist grip 51 is finished, the passenger releases the grip body 53 at the use position. Then, the grip body 53 automatically returns from the use position to the storage position by the elastic force of the torsion coil spring 57.

[0004]

However, in the above-mentioned conventional assist grip 51, when the passenger releases his / her hand from the grip body 53, the grip body 53 is automatically rotated by the elastic force of the torsion coil spring 57. . Then, when the grip body 53 returns to the storage position, there is a problem that the ceiling 55 and the like are vigorously hit and a tapping sound is emitted.

Further, when the base body 52 is attached to the ceiling 55 in a state different from a predetermined state (for example, in a slightly inclined state) at the time of manufacturing a vehicle, the grip body 53 is rotated when the grip body 53 is rotated. Grip body 53 and base 5
2 may come into contact with each other to generate a frictional force. For this reason,
If the elastic force of the torsion coil spring 57 is not sufficiently large, the grip body 53 may not return to the storage position due to the frictional force when the grip body 53 is stored in the use position. .

If the elastic force of the torsion coil spring 57 is not sufficiently large, the grip body 53 in the retracted position may flutter when the vehicle runs on a bumpy road or the like and vibrates greatly.

Further, in the prior art, the assist grip 5
When not in use, the grip body 53 is always held in the storage position. For this reason, when the passenger tries to grasp the grip body 53 quickly, the grip body 53 has to be once rotated to the use position, and there is a problem that it is difficult to use.

The present invention has been made to solve the above-mentioned problems, and its purpose is to prevent the tapping sound from being generated by the grip body at the end of use, and to securely store the grip body at the storage position when not in use. An object of the present invention is to provide an assist grip capable of holding the grip body in the use position even when not in use, by suppressing the fluttering by holding the grip body in place, and considering the case of quickness.

[0009]

In order to achieve the above object, an assist grip according to a first aspect of the present invention comprises a base body fixed to a vehicle main body, and a pivotally supported by the base body by a shaft, and gripped by a passenger. And a protrusion and a recess provided between the base body and the grip body, which are engaged with each other when the grip body is rotated to the storage position and hold the grip body in the storage position. Provided between the first engagement means and the base body and the grip body,
The grip main body is engaged with each other when the grip main body is rotated to the use position, and the second engagement means includes a protrusion and a recess for holding the grip main body in the use position.

In addition to the structure of the first aspect of the invention, a second aspect of the invention is to attach the shaft to the grip body, and to disengage the protrusion and the recess of each engaging means from the base. Direction in which a long hole for allowing the shaft to move in the direction is provided, the shaft is inserted into the long hole, and the protrusion and the recess in each engaging means are engaged with each other on the base. An elastic member for urging the shaft is provided.

[0011]

In the first aspect of the invention, the grip body is gripped by the passenger and rotated about the shaft. By the rotation, when the grip body reaches the retracted position, the protrusion and the recess of the first engaging means engage with each other. This engagement holds the grip body in the retracted position. Further, when the grip body reaches the use position by the rotation, the projection and the recess of the second engaging means are engaged with each other. This engagement holds the grip body in the use position.

Therefore, when the grip body is rotated, the elastic force of the torsion coil spring or the like is not applied as the rotational urging force. Therefore, when the grip body in the use position is rotated to the storage position, it does not vigorously hit the vehicle body or the base body.

Further, if the base body is attached to the vehicle body in a state different from a predetermined state at the time of manufacturing the vehicle, the grip body and the base body come into contact with each other when the grip body rotates. May cause friction. When a torsion coil spring or the like having a small elastic force is used to rotate the grip body to the retracted position, the elastic force cannot overcome the friction force and the grip body rotates to a predetermined retracted position. It may not move.

However, in the first aspect of the present invention, the elastic force of the torsion coil spring or the like is not used, and the grip body is rotated manually. Here, in general,
It is possible to obtain a force larger than the elastic force of the torsion coil spring or the like. Therefore, if a turning force of a magnitude that overcomes the frictional force is manually applied to the grip body, the grip body can be rotated to the storage position.

Further, when the grip body is rotated to the storage position or the use position, the protrusions and the recesses of the engaging means engage with each other. This engagement restricts the rotation of the grip body. Therefore, it is possible to prevent the grip body in the storage position from fluttering due to vibration of the vehicle or the like.

Further, the holding position (storage position or use position) of the grip body can be arbitrarily switched by the passenger. Therefore, for example, if the grip main body is held in the use position by the second engagement means in case the passenger is in a hurry, the passenger can instantaneously turn the grip main body without rotating the grip main body. It is possible to grip the grip body in the use position.

If the shaft is immovable when the grip body in the storage position or the use position is rotated, the engagement between the protrusion and the recess in each engaging means is released to disengage the grip body. In order to rotate, it is necessary to bend at least one of the grip body and the base body.

However, in the second aspect, the shaft can be moved along the elongated hole against the biasing force of the elastic member. Therefore, it is possible to release the engagement between the protrusion and the recess in each engagement means without bending the grip body and the base body.

Further, in the second invention, when the grip body is rotated to the storage position or the use position, the elastic member biases the shaft in the direction in which the projection and the recess are engaged with each other. Therefore, it is possible to reliably hold the grip body in the storage position or the use position, even though the shaft is movable along the elongated hole as described above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the first and second inventions are embodied in an assist grip mounted on a vehicle ceiling or the like will be described below with reference to FIGS.

As shown in FIG. 1, the assist grip of this embodiment comprises a pair of bases 1 (only one of which is shown). As shown in FIGS. 1 and 3, each base body 1 includes a main body member 2,
The spacer 3 and the cover 4 are provided. The main body member 2 is in the shape of a substantially elongated cylinder with a bottom. The bottom wall 2a of the main body member 2 is provided with a through hole 6 into which a fastening member 5 such as a bolt can be inserted. An annular projection 7 is formed around the through hole 6 in the bottom wall 2a.

The spacer 3 is sandwiched between the ceiling 8 forming a part of the vehicle body and the bottom wall 2a of the body member 2, and the annular projection 7 is fitted into the ceiling 8.
In this state, the fastening member 5 is inserted into the through hole 6 of the body member 2, and the body member 2 is fixed to the ceiling 8 by fastening the fastening member 5.

On the bottom wall 2a, a positioning pin 9 is provided in the vicinity of the annular projection 7 so as to project. The pin 9 is inserted into a positioning hole (not shown) in the ceiling 8 to prevent the main body member 2 from being displaced from the ceiling 8.

A cover 4 is attached to the main body member 2, and the fastening member 5 and the like in the main body member 2 are covered by the cover 4. A grip body 11 made of synthetic resin, which is gripped by a passenger, is rotatably connected to the body member 2. More specifically, a pair of bearing portions 12 is formed on the lower side of the main body member 2. As shown in FIG. 4, both ends of the grip body 11 (only one of which is shown in FIG. 4) are provided with recesses 13 having a size capable of accommodating the cover 4. At the end of the grip body 11,
A pair of support holes (only one side is shown in FIG. 4) 14 are formed so as to sandwich the recess 13. Then, the both bearing portions 1
The shaft 15 is inserted through the shaft 2, and both ends of the shaft 15 are fitted into the corresponding support holes 14. Therefore, the grip body 11
Is rotatable about the shaft 15.

In addition to the basic structure described above, in this embodiment, the following structure is adopted in order to hold the grip body 11 in the storage position of FIG. 1 or the use position of FIG. As shown in FIG. 3, each bearing portion 12 in the main body member 2
A projection 16 is integrally formed on the lower surface of the entire width of the projection. In addition, as shown in FIG.
A partition wall 17 is formed between the two support holes 14 at each end. A pair of recesses 18 and a pair of recesses 19 are formed on both sides of the partition wall 17. Both recesses 18 engage with the protrusion 16 when the grip body 11 is rotated to the retracted position in FIG. Both recesses 19 engage with the protrusion 16 when the grip body 11 is rotated to the use position shown in FIG.

In this embodiment, the protrusion 16 and the both recesses 18 form the first engaging means, and the protrusion 16 and the both recesses 19 form the second engaging means. Therefore, the protrusion 16 serves as both the first engaging means and the second engaging means.

Furthermore, in this embodiment, the bearing portion 12 supports the shaft 15 in a vertically elongated slot 21.
Has become. These long holes 21 move the shaft 15 in a direction (in this case, downward) in which the protrusion 16 and the recess 18 engaged with each other are released when the grip body 11 in the storage position is rotated. Tolerate. Further, when the grip body 11 in the use position is rotated, the long hole 21 moves the shaft 15 in a direction (in this case, downward) in which the protrusion 16 and the recess 19 which are engaged with each other are released. Tolerate.

In addition, in this embodiment, as shown in FIG. 1, the end portion of the leaf spring 23 as an elastic member is engaged between both bearing portions 12 of the main body member 2. Leaf spring 23
Is bent, and the shaft 1 is formed by the lower part of the shaft 1.
The middle part of 5 is supported. The leaf spring 23 has the protrusion 1
The shaft 15 is biased in a direction (in this case, upward) in which the 6 and the recess 18 (or 19) are engaged with each other.

In the assist grip of this embodiment constructed as described above, the grip body 11 is gripped by the occupant and rotated about the shaft 15. When the grip body 11 reaches the storage position shown in FIG. 1 by the rotation,
The protrusion 16 and the recess 18 are engaged with each other. By this engagement, the grip body 11 is held at the storage position. Also,
When the grip body 11 reaches the use position shown in FIG. 2 by the rotation, the protrusion 16 and the recess 19 are engaged with each other. By this engagement, the grip body 11 is held in the use position.

Therefore, when the grip body 11 is rotated, unlike the prior art, the elastic force of the torsion coil spring or the like is not applied. For this reason, when the grip body 11 in the use position is rotated to the storage position, it does not vigorously hit the ceiling 8 or the base body 1 and generate an abnormal noise.

When the vehicle body is manufactured, if the base body 1 is attached to the ceiling 8 in a state different from a predetermined state (for example, in a slightly inclined state), the grip body 11 is rotated, The grip body 11 and the base body 1 may come into contact with each other to generate a frictional force. Then, in order to rotate the grip body 11 to the retracted position,
If a torsion coil spring with a small elastic force is used,
In some cases, the elastic force cannot overcome the frictional force and the grip body 11 does not rotate to a predetermined storage position.

However, in this embodiment, the elastic force of the torsion coil spring or the like is not used, and the grip body 11 is rotated manually. Here, in general,
It is possible to obtain a force larger than the elastic force of the torsion coil spring or the like. Therefore, if a turning force of a magnitude that overcomes the frictional force is manually applied to the grip body 11, the grip body 11 can be rotated to the retracted position.

Further, when the grip body 11 is rotated to the retracted position, the projection 16 and the recess 18 engage with each other. Further, when the grip body 11 is rotated to the use position, the protrusion 16 and the recess 19 are engaged with each other. By the engagement of the protrusion 16 and the recess 18 (or 19),
Rotation of the grip body 11 is restricted. Therefore, even if the vehicle travels on a bumpy road or the like and vibrates greatly, the grip body 11 at the storage position does not flutter.

Further, the occupant can arbitrarily switch the holding position (storage position and use position) of the grip body 11. Therefore, for example, the grip body 11 can be held at the use position even when the assist grip is not used. In this way, the passenger can grip the grip body 11 in an instant without rotating the grip body 11 in the case of a quick start.

By the way, it is assumed that the shaft 15 is immovable when the grip body 11 in the storage position or the use position is rotated. In this case, it is necessary to bend at least one of the grip body 11 and the base 1 in order to release the engagement between the protrusion 16 and the recess 18 (or 19) and rotate the grip body 11.

However, in this embodiment, the shaft 15 can be moved along the elongated hole 21 against the elastic force of the leaf spring 23. Therefore, the protrusion 16 and the recess 18 (or 19) can be disengaged without bending the grip body 11 or the base body 1.

In addition, in this embodiment, the grip body 11
When is rotated to the storage position or the use position, the leaf spring 23 biases the shaft 15 in a direction in which the protrusion 16 and the recess 18 (or 19) are engaged with each other. By this bias, the protrusion 16
Also, the engagement of the recess 18 (or 19) is surely performed. Therefore, although the shaft 15 can move along the long hole 21 as described above, the grip body 11 can be reliably held in the storage position or the use position, and rattling can be prevented in advance. .

The present invention is not limited to the configuration of the above embodiment, and may be arbitrarily modified within the scope not departing from the spirit of the invention, for example, as follows. (1) In the above embodiment, the first and second projections 16 are used.
Although both of the engaging means are also used, a protrusion may be provided for each engaging means. For example, as shown in FIGS. 5 and 6, a protrusion 24 is formed on the upper end of the cover 4. Grip body 11
Is rotated to the storage position shown in FIG.
A recess 18 that engages with is formed in the grip body 11.
Then, the protrusion 24 and the recess 18 constitute a first engaging means.

A protrusion 25 is formed on the lower end of the spacer 3. When the grip body 11 is rotated to the use position shown in FIG. 6, a recess 19 that engages with the protrusion 25 is formed in the grip body 11. Then, the projection 25 and the recess 19 constitute a second engagement means.

Even with such a modification, the same operation and effect as those of the above-described embodiment can be obtained. (2) The elastic member in the above embodiment may be any member as long as it biases the shaft 15 in the direction in which the protrusion 16 and the recess 18 (or 19) are engaged with each other. A spring may be used.

(3) The projections and depressions 16 and the depressions 18 (or 19) in the above-described embodiment may be reversed. In this case, the protrusion is provided on the grip body 11 and the recess is provided on the base 1.

(4) The assist grip of the present invention can be applied not only to vehicles but also to vehicles such as ships and airplanes.

[0043]

As described in detail above, according to the first aspect of the present invention, the tapping sound generated by the grip body is prevented at the end of use, and when not in use, the grip body is securely held in the storage position to prevent fluttering. Can be suppressed. Further, the grip body can be held in the use position even when it is not used, and the ease of use can be improved in the case of an emergency.

According to the second aspect of the invention, in addition to the effect of the first aspect of the invention, when the grip body is rotated, the protrusions and the recesses in each engaging means are not bent without bending the grip body and the base body. Can be released. In addition, when holding the grip body in the storage position or the use position,
The elastic member can surely engage the protrusion and the recess in each of the engaging means to prevent rattling.
