Description

The present invention relates to a vehicle having a pop-up member that raises a seat when releasing the locked state of the seat.

The seat of the saddle-ride type vehicle has a base end portion that is rotatably fixed to the vehicle body via a hinge, and a free end portion that is detachably attached to the vehicle body via a lock mechanism.

The lock mechanism includes a fixed locking member and a movable locking member. The fixed locking member is fixedly attached to the sheet. The movable locking member is movably attached to the vehicle body. By engaging the movable locking member with the fixed locking member, the seat is fixed to the vehicle body and is locked. The locked state of the seat is released by the following method. When the key is inserted into the key hole of the key cylinder and rotated, the movable locking member is pulled through the wire and separated from the fixed locking member.

The locking mechanism has the following problems. The movable locking member is always urged by a spring or the like in a direction to engage with the fixed locking member. Therefore, when the rotation of the key is stopped in the process of releasing the locked state of the seat, the key returns to the initial position and the movable locking member engages with the fixed locking member. As a result, the seat is locked again.

In order to solve the above problem, it has been proposed to provide a member (damper rubber or pop-up member) that forcibly raises the seat when the seat is unlocked. Even when the key returns to the initial position, the fixed locking member moves upward of the vehicle body as the seat rises, so that the movable locking member does not engage the fixed locking member.

Japanese Utility Model Laid-Open No. 58-41680 discloses a damper rubber as the member as shown in FIG. The damper rubber 200 is fixed to the vehicle body 212 and is disposed between the seat bottom plate 210 and the vehicle body 212. The damper rubber 200 has protrusions 202, 204, and 206 at the top. The heights L1 of the protrusions 202 and 206 are set so that the upper ends of the protrusions 202 and 206 are in contact with the sheet bottom plate 210 when the movable locking member 218 is engaged with the fixed locking member 216. . Since the protrusion 204 is higher than the protrusions 202 and 206, the protrusion 204 is compressed by the sheet bottom plate 210 when the sheet 214 is tilted down. Due to the compressive deformation of the protrusion 204, the sheet bottom plate 210 abuts on the upper ends of the protrusions 202 and 206, the movable locking member 218 engages with the fixed locking member 216, and the seat 214 is locked. . In the process of releasing the locked state of the seat 214, the seat 214 rises above the vehicle body 212 due to the elastic force of the protrusions 204.

In Japanese Utility Model Publication No. 2001-130465, as shown in FIG. 2, a pop-up member is disclosed as the member. The pop-up members 220 and 220 are provided integrally with the seat bottom plate 222 and are disposed between the seat bottom plate 222 and the vehicle body. The pop-up members 220 and 220 are formed in a tongue shape and extend to the vehicle body side. When the seat is tilted, the pop-up members 220 and 220 are compressed by the vehicle body. Due to the compression deformation of the pop-up members 220, 220, the seat bottom plate 222 comes into contact with the vehicle body, the movable locking member engages with the fixed locking member, and the seat is locked. In the process of releasing the locked state of the seat, the seat rises above the vehicle body by the elastic force of the pop-up members 220 and 220. At this time, since the elastic force of the pop-up members 220 and 220 acts in the rotation direction of the sheet, it is effectively used for the rising of the sheet.

The conventional damper rubber 200 has the following problems. In the process of fixing the seat 214 to the vehicle body 212, the protrusion 204 is compressed by the seat bottom plate 210 while receiving the load of the seat 214. Therefore, the durability of the damper rubber 200 is low. Further, in the process of releasing the locked state of the seat 214, the elastic force of the projection 204 acts in the vertical direction of the vehicle body 212, and therefore is not used effectively for the rising of the seat 214.

The conventional pop-up member 220 has the following problems. In the process of fixing the seat to the vehicle body, the pop-up member 220 is compressed by the seat bottom plate 222 while receiving the load of the seat. Therefore, the durability of the pop-up member 220 is low.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. As shown in FIG. 3, the seat 1 includes a base end portion 1 a that is rotatably fixed to a motorcycle body 11 via a hinge 2, and a free end portion that is detachably attached to the vehicle body via a lock mechanism. 1b.

The sheet 1 includes a striker 3 (fixed locking member) and pop-up members 5 and 5 on the back surface 1c of the free end 1b. The striker 3 is a part of a lock mechanism for fixing the seat 1 to the vehicle body 11. The pop-up members 5 and 5 forcibly raise the seat 1 above the vehicle body 11 when releasing the locked state of the seat 1. By using two pop-up members, the load of the sheet 1 is dispersed and the rising of the sheet 1 is reinforced. The striker 3 and the pop-up members 5 and 5 are linearly arranged in the width direction of the sheet 1 on the back surface 1c of the free end 1b. The pop-up members 5 and 5 are respectively arranged on both sides of the striker 3. In the present embodiment, two pop-up members are used. However, the present invention is not limited to this, and an even number of pop-up members are used, and the same number is provided on both sides of the striker 3 along the width direction of the sheet 1. You may arrange.

The pop-up member 5 includes a load receiving part 51 and an elastic part 53. The pop-up member 5 is disposed on the back surface 1 c in the order of the load receiving portion 51 and the elastic portion 53 from the base end portion 1 a side along the longitudinal direction of the sheet 1.

As shown in FIG. 4, the load receiving part 51 is formed in a rectangular parallelepiped shape. In the process of fixing the seat 1 to the vehicle body 11, the load receiving portion 51 receives the load of the seat 1 by bringing the load receiving surface 51 c into contact with the vehicle body 11. The height L2 of the load receiving portion 51 is not less than the height of the striker 3.

The elastic part 53 has a substantially J-shaped cross section and is made of an elastic member such as rubber. The elastic portion 53 has a base portion 53a and a free portion 53c and bends when the seat 1 is locked. In addition, the elastic portion 53 causes the seat 1 to rise above the vehicle body 11 along the rotational direction of the seat 1 by the elastic force generated by bending when the seat 1 is unlocked.

The base 53a is integrally connected to an upper portion of the end surface 51a of the load receiving portion 51 at one end. The upper end surface 53 b of the elastic portion 53 extends from the upper end surface 51 b of the load receiving portion 51 in the longitudinal direction of the pop-up member 5. The free portion 53c is integrally connected to the other end of the base portion 53a and extends downward. A space 55 is formed between the load receiving portion 51 and the free portion 53c of the elastic member 53 below the base 53a. The height L3 of the free portion 53c is larger than the height L2 of the load receiving portion 51. Note that the load receiving portion 51 may be formed of an elastic member such as rubber, and the entire pop-up member 5 may be formed of an elastic member.

An attachment member 9 for fixing the pop-up member 5 to the back surface 1c of the free end 1b of the seat 1 is provided on the upper end surface 51b of the load receiving portion 51. The attachment member 9 is formed of an elastic member such as rubber.

Next, the structure of the back surface 1c will be described. As shown in FIG. 5A, the sheet-side mounting plate 21 is provided on the back surface 1c. The attachment hole 21 a is formed in the seat side attachment plate 21. The pop-up member 5 is fixed to the seat 1 by inserting the attachment member 9 into the attachment hole 21 a and fitting the attachment member 9 into the seat 1. In this state, the upper end surface 51 b of the load receiving portion 51 abuts on the seat side mounting plate 21. Further, the seat-side mounting plate 21 has a recess 23 that is recessed toward the seat 1 in a region facing the upper end surface 53 b of the elastic portion 53. In a state in which the lock of the seat 1 is released, the seat-side mounting plate 21 is separated from the upper end surface 53b of the elastic portion 53 by an interval L4.

The operation of the pop-up member 5 is as follows.

In the state where the seat 1 is unlocked, as shown in FIG. 5A, the pop-up member 5 has the free portion 53 c of the elastic portion 53 extending straight, and the load receiving surface 51 c of the load receiving portion 51 does not contact the vehicle body 11. .

In the process of fixing the seat 1 to the vehicle body 11, the pop-up member 5 is deformed as follows. First, the load receiving surface 51c contacts the vehicle body 11 from the end surface 51d side. When the load receiving surface 51c contacts the vehicle body 11 by a predetermined area, the free portion 53c contacts the vehicle body 11. Here, the predetermined area is an area where the load of the sheet 1 applied to the load receiving portion 51 is always larger than the load of the sheet 1 applied to the free portion 53c. Furthermore, when the sheet 1 falls down, the base 53 a of the pop-up member 5 is bent, and the upper end surface 53 b of the pop-up member 5 enters the recess 23. When the upper end surface 53 b comes into contact with the end surface 23 a of the recess 23, the free portion 53 is bent between the seat 1 and the vehicle body 11 so as to swell to the opposite side of the load receiving portion 51. In the bending of the free part 53c, the height L3 of the free part 53c is set so that the end of the free part 53c does not exist between the load receiving surface 51c and the vehicle body 11, so that the free part 53c is the seat 1 Does not interfere with the operation.

In the locked state of the seat 1, as shown in FIG. 5B, the free member 53c and the load receiving portion 51 of the pop-up member 5 abut against the vehicle body 11. The free part 53 c is bent between the seat 1 and the vehicle body 11. The load receiving portion 51 is pressed against the vehicle body 11 by the seat side mounting plate 21 and receives the load of the seat 1. In this state, the pin (movable locking member) 101 provided on the vehicle body 11 is engaged with the striker 3 provided on the seat 1, and the seat 1 is fixed to the vehicle body 11.

In the process of releasing the locked state of the seat 1, the elastic portion 53 returns to the original state by the elastic force generated along the rotation direction of the seat 1 by bending. At this time, the pop-up member 5 causes the seat 1 to rise along the rotational direction of the seat 1 via the seat-side attachment portion 21.

In the pop-up member 5, the load receiving part 51 receives the load of the sheet 1, and the elastic part 53 raises the sheet 1 using the elastic force generated in the rotation direction of the sheet 1. Therefore, since the pop-up member 5 can be divided into a portion that receives the load of the sheet and a portion that generates elastic force, durability is improved. Further, since the elastic force of the elastic portion 53 is generated along the rotation direction of the sheet 1 by bending, it is effectively used for the rising of the sheet 1.

The configuration of the lock mechanism will be described below. As shown in FIGS. 9 and 10, the lock mechanism includes the striker 3, the pin 101, the wire 105, the wire termination members 105 a and 105 b, the wire attachment member 107, the key cylinder 109, the key hole portion 111, the protective tube 113, and the cylindrical member. 115a and 115b, a spring 121, a fixing pin 162, a guide member 163, and a spring holding pin 164.

The inclined portion 101a of the pin 101 engages with the striker 3 to bring the seat 1 into a locked state. As shown in FIG. 3, the key cylinder 109 is provided at the rear portion of the vehicle body and has a key hole 111 for inserting the key 123. The wire attachment member 107 is provided on the side opposite to the key hole 111 of the key cylinder 109.

The wire 105 connects the pin 101 and the key cylinder 109. The wire 105 is accommodated in the protective tube 113 except for the vicinity of both ends. One end of the wire 105 is accommodated in a wire termination member 105 a provided at the tip of the wire attachment member 107. The other end of the wire 105 passes through a notch 101c formed in a substantially U shape in the short piece 101b of the pin 101, and is accommodated in the wire termination member 105b. The wire termination member 105b is formed in a cylindrical shape and has a width larger than that of the notch 101c. Cylindrical members 115 a and 115 b for fixing the lock mechanism to the vehicle body 11 are provided at both ends of the protective tube 113.

The spring 121 extends along the pin 101 and is provided on the side of the pin 101. One end of the spring 121 is fixed to a fixing pin 162 provided on the vehicle body 11. The other end of the spring 121 is fixed to a spring holding pin 164 provided on the inclined portion 101a side of the pin 101 with respect to the wire terminal member 105b. In the natural length of the spring 121, the pin 101 is engaged with the striker 3, as shown in FIG.
The guide member 163 is fixed to the vehicle body 11. The guide member 163 extends along the pin 101 and guides the movement of the pin 101. The guide member 163 has a bent portion 163 a provided in parallel with the short piece portion 101 b of the pin 101. The cylindrical member 115b is fitted into a notch 163b formed in the bent portion 163a and is fixed to the vehicle body 11.

The operation of the locking mechanism will be described below.

When the seat 1 is tilted, as shown in FIG. 9, the tip of the inclined portion 101a of the pin 101 is engaged with the striker 3 provided on the back surface 1c of the free end portion 1b of the seat 1, and the seat 1 is locked. become.

In the process of releasing the locked state of the seat 1, when the key 123 is inserted into the key hole 111 of the key cylinder 109 and rotated in the direction of the arrow 131 (clockwise) as shown in FIG. Rotates in the direction of arrow 133 (clockwise). As the wire attachment member 107 rotates, one end of the wire 105 is pulled in the direction of the arrow 135.

When one end of the wire 105 moves in the direction of the arrow 135, the wire termination member 105 b attached to the other end of the wire 105 moves in the direction of the arrow 137. At this time, when the wire terminal member 105 b is caught by the short piece portion 101 b of the pin 101, the short piece portion 101 b of the pin 101 also moves in the direction of the arrow 137. Therefore, when the key 123 is inserted into the key hole 111 and rotated in the direction of the arrow 131, the pin 101 moves in the direction of the arrow 137 while the spring 121 is extended. As a result, the inclined portion 101a of the pin 101 moves away from the striker 3, and the locked state of the seat 1 is released.

When the pin 101 moves away from the striker 3, the pop-up members 5 and 5 raise the sheet 1. Therefore, even if the pin 101 moves in the direction opposite to the arrow 137 due to the elastic force of the spring 121, the striker 3 moves together with the seat 1 above the vehicle body 11, and therefore does not engage with the pin 101.

Next, a first modification of the present embodiment will be described with reference to FIGS. 6A to 6D. The pop-up member 50 is different from the pop-up member 5 in that the adjustment protrusion 81 is provided on the seat side attachment portion 21.

As shown in FIG. 6A, the adjustment protrusion 81 is attached to the seat side mounting plate 21 so as to face the upper end surface 53 b of the elastic portion 53 in the recess 23 of the seat side mounting plate 21. As shown in FIG. 6B, the adjustment protrusion 81 extends toward the vehicle body 11 and is elongated along the longitudinal direction of the seat 1.

In the locked state of the seat 1, as shown in FIGS. 6C and 6D, the upper end surface 53b of the elastic portion 53 is in contact with the adjustment protrusion 81. Therefore, by adjusting the height of the adjustment protrusion 81, the entry of the base 53a into the recess 23a and the bending of the free portion 53b are optimally adjusted. As a result, the magnitude and direction of the elastic force generated by the bending of the elastic portion 53 is appropriately adjusted.

Next, a second modification of the present embodiment will be described with reference to FIGS. 7A and 7B. The pop-up member 100 differs from the pop-up member 5 in the structure of the recess 23 and the connection structure of the load receiving portion 51 and the elastic portion 53.

The base portion 53 a of the elastic portion 53 is integrally connected to the central portion of the end surface 51 a of the load receiving portion 51. The upper end surface 53b of the elastic portion 53 extends in the longitudinal direction of the pop-up member 100 from the upper center of the end surface 51a. The height L3 'of the free portion 53c of the elastic portion 53 is larger than the length L2' from the center upper portion of the load receiving portion 51 to the load receiving surface 51c.

In a state where the pop-up member 100 is fixed to the seat side mounting plate 21 via the mounting member 9, the upper end surface 51 b of the load receiving portion 51 contacts the seat side mounting plate 21. Since the upper end surface 53b of the elastic portion 53 extends in the longitudinal direction of the pop-up member 100 from the center upper portion of the end portion 51a, a recess 33 is formed between the upper end surface 53b and the seat side mounting plate 21. . Therefore, the seat-side mounting plate 21 does not need to be formed with a recessed portion recessed on the sheet 1 side in a region facing the upper end surface 53b, so that the manufacturing cost can be reduced and the manufacturing efficiency can be improved.

Note that the adjustment protrusion 81 may be provided on the seat-side mounting plate 21 so as to face the upper end surface 53 b of the elastic portion 53 inside the recess 33.

Next, a third modification of the present invention will be described with reference to FIG. The pop-up member 110 is different from the pop-up member 5 in that the gap 55 is divided into two parts.

Below the base portion 53 a of the elastic portion 53, the connecting portion 51 e is disposed along the longitudinal direction of the pop-up member 110 between the load receiving portion 51 and the free portion 53 c of the elastic portion 53. The gap portion 55 is divided into two by the connecting portion 51d. Therefore, in the locked state of the seat 1, the free portion 53 c is reliably bent between the seat 1 and the vehicle body 11 so as to swell to the side opposite to the load receiving portion 51.

In the present embodiment, the load receiving portion 51, the elastic portion 53, and the mounting member 9 may be separately manufactured, and then these members may be connected to complete the pop-up member.

The pop-up member may be completed by integrally forming the load receiving portion 51, the elastic portion 53, and the mounting member 9 with an elastic member such as rubber. At this time, the elastic characteristics of each member may be different depending on each application.

In the present embodiment, the case where the pop-up member 5 is fixed to the seat 1 has been described. However, the present invention is not limited to this, and the pop-up member is fixed to the vehicle body by changing the arrangement of the base portion and the free portion of the elastic portion. It can also be applied to cases.

Since the pop-up member can separate a portion receiving the load of the sheet (load receiving portion) and a portion generating the elastic force (elastic portion), durability is improved. Further, since the elastic force of the elastic portion is generated along the rotation direction of the sheet by bending, it is effectively used for the rising of the sheet.
