Vibration prevention device for turning / external lifting mechanism. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the turning of a seat in a vehicle according to the present invention will be described.
A vibration preventing device for an external lifting mechanism will be described with reference to the drawings as an example of the embodiment. First, a description will be given of a seat turning / out-of-vehicle elevating mechanism of a vehicle.
The bottom plate 3 attached only, provided upright pivot 4 to the center, to pivotally support base 5 rotatable in this pivot around the inward of the U-shaped rail portions 6 on both side edges of the pedestal 5 The rail frames 7, 7 are mounted via mounting plates 8, 8. 9 is a stand
In this embodiment, the turning auxiliary support rings are attached to the lower surface of the seat 5 and are arranged at four positions to turn on the bottom plate 3. A slide support frame 11 having rollers 10 projecting from front and rear ends is provided, and each roller 10 is engaged with the U-shaped rail portion 6, 6 of the rail frames 7, 7, and the rail frame 7,
2 and a vertical support frame 12 is integrally supported on the rear of the slide support frame 11, and its position is changed up and down as shown in FIG. , 14 and the lower end of the drive link arm 15 by the front support shaft 13 and the rear support shaft 1.
4, the lower end of the driven link arm 16 is pivotally supported,
The upper end of the opposite drive link arm 15 and the upper end of the driven link arm 16 are connected to the connecting plate 1 at the rear end of the lifting frame 17.
A lever 21 which is supported by the support shafts 8 and 18 by support shafts 19 and 20 which are provided at the same interval as the lower support shafts 13 and 14 and is connected to the lower end of the drive link arm 15 at a required angle.
A hydraulic motor 24 that expands and contracts the action points at both ends by a cylinder 22 and a piston rod 23 is pivotally connected to the end of the motor shaft 12 and the upper end of the driving support frame 12 by support shafts 25 and 26. Then, the seat 27 is supported on the lifting frame 17. An operation shaft 29 is rotatably supported on a bearing 28 attached to a front portion of the pedestal 5, and an operation handle 30 is provided at one end thereof.
And tilt the upper end forward or backward so that the operating shaft 29
Is provided so as to be able to rotate by a required angle. When the operating handle 30 is tilted backward, the locking pin 31 for stopping the slide support frame 11 from sliding back and forth with respect to the pedestal 5 is lowered on the operating shaft 29, and the locking portion at the tip thereof is lowered. From the engaging hole 33 of the front engaging portion 32 integral with the front portion of the elevating frame 17 or the engaging hole 35 of the rear engaging portion 34 integral with the rear portion of the slide support frame 11. The slide bearing frame 11 is released integrally from the state where the slide bearing frame 11 is locked to the pedestal 5 or is slidably provided forward or backward. Similarly , the operating shaft 29 has an operating handle 3
When 0 is tilted forward, the locking pin 38 for stopping the pedestal 5 rotatable around the axis of the pivot 4 with respect to the bottom plate 3 is raised,
The engaging portion of the tip to the bottom plate 3, removed from the right rotation lock engaging hole 36 or the left rotation lock engaging hole 37 is formed in agreement with the turning angle of the base 5, engaging the seat 5 to the bottom plate 3 It is released from the stopped state and is provided so as to be pivotable on the right or left side. [0011] The supporting plates 39 and 40 of the L-shaped on the upper surface of the bottom plate 3 welded erected, the locking screw 41 screwed into the support plate 39 of L-shaped,
The tip of the pedestal 5 is arranged to correspond to the front-facing position by turning the pedestal 5 counterclockwise, and when the corresponding side circumference of the pedestal 5 collides, the locking pin 38 mounted on the pedestal 5 is turned to the right-turn locking engagement hole of the bottom plate 3. 36
Is provided so as to be engaged with. [0012] Also in support plate 40 of the L-shaped locking screw 42
The pedestal 5 is turned to the right so that the pedestal 5 is turned to the right and the position corresponding to the sideways position. When the corresponding side circumference of the pedestal 5 collides, the locking pin 38 mounted on the pedestal 5 turns the bottom plate 3 to the left. It is provided to engage with the lock engagement hole 37. [0013] The locking screw 41 of the L-shaped support plate 39 and 40,
Tip in contact with the surface of the 42 is not limited to the side periphery of the pedestal 5 are those where or bearing frame including a rail frame 7 and 7 as long as it is connected to the base 5.
In addition, 43 and 44 are lock nuts. The cylinder 22 and the piston rod 23
As a matter of course, the hydraulic prime mover 24 that expands and contracts the action points at both ends is connected to a hydraulic device installed in the vehicle cabin 1 by an oil feed pipe. When the hydraulic motor 24 is of a single-acting type, that is, when the seat 27 is lowered out of the passenger compartment 1, the cock of the hydraulic circuit is opened to return the oil to the oil reservoir by its own weight and to operate. The raising of the seat 27 sends oil from the hydraulic circuit to the hydraulic motor 24 to operate. In the final stage, the spring is compressed and stopped, and when the hydraulic circuit is opened and the lowering operation is performed again, the drive link arm 15 and the driven link arm 16 are pushed out by the return action of the spring until the required angle is inclined. , And then descend under its own weight.
The support frame including the pedestal 5 and the rail frame 7
Make up. Turning of the seat and the outside of the vehicle in the vehicle of the present invention
The vibration preventing device of the lifting mechanism is configured as described above.
Therefore, the seat 27 is turned out of the vehicle through the door opening.
The passenger goes out of the cabin 1 and sits down on the seat 27,
I was pulled into the cabin 1 and got on the bus.
You can get out of the cabin 1 and get off,
Slide and the seat 27 can be turned to the required angle
The operation can be performed by operating the operation handle 30. [0016] Then, the left turning front position of the support frame.
And the right turning sideways position from the bottom plate.
The lock screw, which is screwed into the support plate,
Because the crimping connection is made in the protruding state, the pedestal and the support frame
Vibration caused by the passenger's seat position and running vibration
To get on and off without worry and sit comfortably
it can. According to the present invention, the turning of the seat and the vehicle in the vehicle of the present invention are performed.
Since the vibration prevention device of the outer lifting mechanism is as described above,
The seat of the vehicle comes out of the door opening to the outside of the car and at a low position where it is easy to sit down, so that the elderly and the disabled can sit down and sit down. You can get in and out of the car without difficulty. A lock screw, which is screwed from a bottom plate to a support plate which is set up correspondingly from the bottom plate to the left turning front position and the right turning lateral position of the support frame, press-connects to the support frame in a collision state. Therefore, there is no play between the pedestal and the support frame, so that the vibration caused by the occupant's seat position and running vibration can be prevented, the passenger can get on and off without worry, and can sit comfortably on the seat.
