Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a seat carrying device used for carrying a seat into a vehicle body constituting a one-box type automobile for installation and assembly work, for example. Regarding.

(Prior Art) In general, a one-box type car has two rows of rear seats, including a front seat for the driver, a second seat that can be rotated in the front and rear directions, and a third seat that is a bench seat. be equipped. At the installation and assembly site for these seats, the front seats are carried into the car body by opening the front door, and the rear seats, such as the second and third seats, are carried into the car body by opening the sliding door provided on the side of the car body. They are carried into the vehicle body and installed and fixed.

(Problem to be Solved by the Invention') Conventionally, at all seat installation and assembly sites, workers have directly lifted the seats and carried them into the vehicle body. The front seat is carried into the vehicle body by opening the front door, so the work is relatively easy. However, rear seats such as the second and third seats must be installed by opening a sliding door on the side of the vehicle and transporting the vehicle into the vehicle. In particular, the third seat is located at the rearmost part of the vehicle body, so it has a long transport distance, and is also long and quite heavy. Naturally, it is impossible for a single worker to carry the vehicle into the vehicle; it requires two workers, which is not only inefficient, but also a heavy task that requires a cramped posture. Poor workability.

The present invention has been made in view of the above-mentioned circumstances, and it enables a single worker to carry even the rear seat into the vehicle body, and it also enables a smooth process that greatly reduces the fatigue level of the work. The purpose of the present invention is to provide an automobile seat loading device that operates in a manner that is easy to operate.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a structure in which a planar rectangular column is erected in a vertical direction, a frame is fitted along the column so as to be movable up and down, and an arm member consisting of a plurality of arms that are rotatably supported on a frame body and brought into contact with each other at vertically spaced positions on each circumferential surface of the support column, and that can be bent horizontally on the frame body; The base end of the arm member is attached so as to be rotatable in the horizontal direction, and a seat fork body for removably suspending an automobile seat is provided at the distal end of the arm member, and the arm member and the seat fork body are attached through the frame body. This vehicle seat carrying device is characterized in that it has a drive source that drives the seat up and down, and a balance weight is connected to a connecting portion between the drive source and the frame via a filament.

(Function) In the automobile seat carrying device configured as described above, with the seat suspended on the seat fork body, the drive source drives the frame body vertically, and the operator directly moves the arm member in the horizontal direction. By rotating and moving the seat, the seat can be carried from the suspended position to a predetermined position within the vehicle body. The rollers provided on the frame come in even rolling contact with each peripheral surface of the support column, thereby guiding the frame to move up and down smoothly without twisting. Furthermore, the balance weight has the same weight as the total weight of the frame, arm members, and seat fork, and applies a lifting force to the frame, arm, and seat fork, so the drive source actually lifts the seat. It only needs to have the power to move it up and down, so less power is required.

(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, on one side of a seat carrying device 1 to be described later, a one-box type automobile 2, for example, into which seats are to be carried, is located, and on the other side, a vehicle 2 from which seats are to be carried is located.

As shown in FIGS. 3 and 4, this frame body 7 has a U-shape in plan and is provided with a plurality of rollers 8 that roll into contact with each surface of the outer peripheral surface of the support column 6. That is, rectangular through holes 9, 9 are provided vertically at a predetermined interval between the opposing pieces 7a, 7a constituting the frame 7, and both ends of the through holes 9 are provided. A supporting piece 10.10 is provided in a protruding manner opposite to. The roller 8 has both end shafts rotatably supported by the support pieces 10, 1'0, and a portion of its peripheral wall is inserted into the through hole 9 and is in rolling contact with the side surface of the support column 6. . Pieces 7a, 7a of the frame 7
Both end shaft portions of the roller 8 are rotatably supported at a predetermined interval vertically at the distal end and the proximal end, and support columns 6 are respectively supported.
It is transposed to the side of . In the end, a total of eight rollers 8 are pivotally supported on the frame 7, and two rollers 8, 8 are in rolling contact with each of the four sides of the support 6. On the other hand, there is an even state of tangent.

As shown again in FIGS. 1 and 2, the frame 7 is provided with an arm member 11. This arm member 11 is
A first member is rotatably connected in the horizontal direction via a pin 13 to a pair of holding pieces 12 and 12 integrally provided on the frame body 7.
arm 14, a second arm 16 which is horizontally rotatably connected to the tip of the first arm 14 via a pin 15, and a pin 17 to the tip of the second arm 16.
The third arm 18 is rotatably connected in the horizontal direction via the third arm 18. Therefore, these first. Second
．． The third arms 14.16.degree. 18 are all pivotable horizontally freely relative to each other.

A seat fork body 19 is provided at the tip of the third arm 18 . This seat fork body 19
The suspension rod 20 is vertically displaceably penetrating through the tip of the arm 18, and the fork 21 is bifurcated and provided at the lower end of the suspension rod 20. Above suspension rod 2
0 projects upward from the third arm 18, and is integrally provided with a flange 20a to prevent removal. The flange 20a that is the upper end of this protrusion
A coiled spring 22 is interposed between the upper surface of the third arm 18 and the upper surface of the third arm 18, and is wound around the suspension rod 20. From this, the seat fork body 19 is elastically suspended by the third arm 18. Fork 21 above
As shown in FIG. 6 and below, it is a U-shaped plate that is deformed from the front side to the back side of the seat 3 so as to sandwich the top and bottom surfaces of the seat cushion 3a, and in particular, the upper part 21a has a length that projects from between the seat cushion 3a and the seat back 3b to the back side thereof.

As shown again in FIGS. 1, 2, and 5, a vertically movable cylinder 23, which is a driving source such as a hydraulic cylinder, is erected near the column 6 and along the column 6.

An operating rod 23a that projects upward from this vertically moving cylinder 23
A pair of mounting pieces 24 and 24, which are integrally provided on the frame body 7, are connected to the ends of the frame body 7 via pins 25. That is, by operating an operation switch (not shown) of the vertically movable cylinder 23, the operating rod 23a projects upward or descends, and the frame body 7, arm member 11, and seat fork body 19 are accordingly driven vertically. It looks like this.

Also, a pin 25 connecting the operating rod 23a and the frame 7 is provided.
One end of a rigid filament 26, such as a chain or wire, is connected and fixed to the. The filament body 26 is hooked onto a guide rotating body 27 such as a plurality of sprockets or pulleys provided at the upper end of the support column 6, and is inserted into the interior of the support column 6 from the upper end opening.

A balance weight 28 is provided at the lower end portion of the striatal body 26.
are concatenated. The weight of this balance weight 28 is the weight of the frame 7, arm member 11 and seat fork body 19.
is set approximately equal to the total weight of

Therefore, when the operating rod 23a of the vertically movable cylinder 23 is in the neutral state, the balance weight 28 moves the frame body 7, arm member 11 and seat fork body 19 between the linear body 2
6, the frame body 7 and the arm member 11
And the seat fork body 19 is held and balanced at that position.

Next, the operation of the sheet carry-in device 1 configured in this way will be explained.

The operator holds the tip of the third arm 18 and rotates it in the horizontal direction so that the fork 21 suspended there is substantially opposed to the sheet on the temporary storage table 4 as shown in FIG. If the position of the fork 21 relative to the seat 3 is shifted in either the up or down direction, the operation switch of the vertical movement cylinder 23 is operated to vertically displace the seat fork body 19 together with the frame body 7 and the arm member 11.

As shown in FIG. 7, when the upper piece 21a of the fork 21 comes into contact with the upper surface of the seat cushion 3a, the operation of the vertical movement cylinder 23 is stopped, and the upper piece 21a of the fork 21
g into the gap formed between the seat cushion 3a and the seat back 3b.

At this time, from the shape of the upper surface of the seat cushion 3a and the shape of the upper piece 21a of the fork 21, the fork 2
If the upper piece 21a is simply displaced in the horizontal direction, the tip of the upper piece 21a will come into contact with the seat back 3b, making it impossible to smoothly insert the upper piece 21a into the gap between the seat cushion 3a and the seat back 3b.

Therefore, as shown in FIG. 8, the operator pushes down the upper end flange 20a of the suspension rod 20 against the elastic force of the spring 22, and performs a displacement operation so that the tip of the upper piece 21a of the fork 21 can be easily inserted into the gap. do. Once this tip is inserted into the gap, the fork 21 is further pushed in the horizontal direction to engage the lower piece 21b with the bottom surface of the seat cushion 3a. Therefore, the vertical position of the fork 21 can be finely adjusted.

The operator holds the upper piece 21a and the lower piece 21b of the fork 21.
After confirming that the seat cushion 3a is completely inserted, the operation switch of the vertical movement cylinder 23 is operated to raise the frame 7 together with the seat 3.

As shown in FIG. 9, the sheet 3 is lifted and separated from the temporary storage table 4. In this state, since there is no urging force against the upper end flange 20a of the suspension rod 20, the spring 2
The elastic force of 2 is restored.

The operator holds the tip of the third arm 18 or the seat fork body 19 and holds the first to third arms 14, 16, .
18 is rotated in the horizontal direction, and the seat 3 is opposed to the opening of the vehicle body 2. At this time, the seat 3 is oriented in the same direction as the interior of the vehicle body 2. Once the seat 3 faces the opening of the vehicle body 2, the seat 3 is inserted into the vehicle body 2 so that the third arm 18, the seat fork body 19, and the seat 3 do not come into contact with the periphery of the opening. Then, the seat 3 is moved to a predetermined position inside the vehicle body 2, and the operation switch of the vertical movement cylinder 23 is operated again to lower the seat fork body 19 together with the frame body 7 and the arm member 11.
Lower the seat 3 onto the floor surface of the vehicle body 2.

In addition, as mentioned above, the suspension rod 2 connected to the fork 21
0 is located at the front end of the seat cushion 3a, so the amount of movement of the arm member 11 can be shortened by the length of the seat cushion 3a, and the carrying distance into the vehicle body 2 can be increased.

Then, the operator stops the switch of the vertical movement cylinder 23, removes the fork 21 from the seat 3, takes out the seat fork body 19 together with the arm member 11 from the opening of the car body 2, and then moves the next seat 3 to the next car body. 2, move it toward the temporary storage stand 4, and repeat the above operations.

In this way, by operating the operation switch of the vertical movement cylinder 23 as necessary, the frame 7, arm member 11, and shift fork body 19 are vertically driven with respect to the column 6. There is no twisting with respect to the support column 6, and the displacement is extremely smooth. That is, two rollers 8 are pivotally supported on each surface of the frame 7, and roll into contact with each surface of the support column 6, respectively. The support column 6 has a rectangular shape with a square plane, and the rollers 8 are evenly contacted with each surface of the column.

Moreover, since the balance weight 28 receives and balances the total weight of the frame body 7, arm member 11, and shift fork body 19, the vertical movement cylinder 23
All that is required is the ability to drive it vertically. In this way, even if the load moment when the heavy seat 3 is suspended is extremely large, the vertical movement cylinder 23 requires less capacity and assists the smooth vertical movement of the frame 7. . In addition, there is no shaking when the seat 3 is suspended and moved by the seat fork body 19, and the vehicle body 2
There is less shock when you lower it inside.

The arm member 11 includes first to third arms 14,
16.18, and the suspension rod 20 of the seat fork body 19 is positioned above the front end of the seat cushion 3a in front of the seat 3, so each arm 14.16. The length of 18 is reduced and the radius of rotation is reduced, allowing more freedom in directional adjustment within tight spaces.

Furthermore, since the suspension rod 20, which is the support shaft of the fork 21 that actually suspends the seat 3, is elastically supported by the third arm 18 via the spring 22, the fork 21 can be attached to and detached from the seat 3. At the same time, the amount of vertical movement of the fork 21 can be finely adjusted, making the work extremely easy.

In the above embodiment, the work of transporting the third seat 3 into the vehicle body has been described, but the present invention is not limited to this, and may be used to transport the second seat. Of course, there are no restrictions on the type of car.
