Description

[Detailed explanation of the idea] The present invention relates to an improvement of an automobile door device.

Currently, car door devices open and close by pivoting outward around a vertical axis on one side edge of the door, but this method requires an appropriate amount of space on the side when opening the door. Furthermore, if another vehicle passes by when the door is open, it is extremely dangerous and can easily cause an accident.

The present invention was completed with the aim of providing an automobile door device that does not have the above-mentioned drawbacks, and the illustrated embodiment will be described in detail below.

Reference numeral 1 denotes a vehicle body equipped with a normal pivoting type door 2, and a door device according to the present invention is provided at the middle portion of both sides of the vehicle body 1.

3 is a door that constitutes the main body of the door device according to the present invention, in which vertical reinforcements 5.5 are fixed near both side edges of the door plate 6, and each reinforcement 5 has a lower end protrusion 7 below it. The door plate 6 is provided with a window 4, and the door plate 6 is provided with a window 4, and the door plate 6 is provided with an upper protrusion 8 slightly above the lower end protrusion 7. Reinforcement 10,
A linear pillar 11 and a floor 12 constitute the main components of the vehicle body 1.

The pillar 11 has its upper end connected to the roof reinforcement 10.
The lower end on which the notch 25 is formed is fixed to the floor 12, and as shown in FIG.
fixes the side plate 14, and furthermore, the lower end protrusion 7 and the upper protrusion 8 of the reinforcement 5 are fitted into the rectangular space of the pillar 11, so that the door 3 can freely slide up and down. At the same time, the notch at the lower end allows the door 3 to tilt slightly at the end of its descent and at the beginning of its ascent; however, the lower end protrusion 7 and the upper protrusion 8 may deviate from the hollow portion back and forth, left and right when sliding. There is no such thing.

In addition, the door 3 is raised by a pulley 21 which will be described later by the upper protrusion 8.
When the wire 20 reaches the position shown in FIG. It is.

The upper protrusion 8 and the lower end protrusion 7 have the same shape as short cylinders, and are fixed to the reinforcement 5 in a T-shape.

Reference numeral 15 denotes a cam that is engaged when the lower end protrusion 7 is at the end of its descent and at the start of its ascent, and presses the lower and upper ends of the door 3 outward using the upper protrusion 8 as a fulcrum. It is rotatably supported by a pin 17 of a member 16 implanted from the floor 12 at the lower end, and has an upper arm 18 and a lower arm 19, and the lower end protrusion 7 engages with this lower arm 19 at the end of the descent. , the lower arm 19 has a spring (not shown) that always presses upward when there is no load on it, and the lower end of the pillar 11 can house the cam 15 as shown in FIGS. 5 and 6. A part of it is cut out.

Further, an electric hoisting device 22 is provided at a predetermined position on the vehicle body 1, and one end of the wire 20 is wound around a drum 23, and the other end is attached to a pulley fixed to the hollow part of the pillar 11 and the vehicle body 1. This hoisting device 22 is directly connected to a motor 24 operated by a push button or key provided near the driver's seat and, if necessary, on the vehicle body 1.

The motor 24 is of a type that automatically stops at the end of hoisting and lowering.

In the device configured as described above, when the driver wants to open the door 3, for example, if the driver presses a push button in the driver's seat to close the circuit of the motor 24 of the hoisting device 22, the motor 24 is activated and the hoisting device 22 is opened. Since it is driven, one end of the wire 20 is wound around the drum 23 of the hoisting device 22, and the other end of the wire 20 is attached to the vertical reinforcement 5 fixed to both side edges of the door plate 6. Since the wire 20 is fixed to the upper protrusion 8, the wire 20 is suspended from a pulley 21 fixed to the hollow part of the pillar 11 and the vehicle body 1 at the intermediate portion, and pulls up the door 3.

Moreover, at the beginning of this winding, as shown in FIG. 6, the lower end protrusion 7 engages with the upper arm 18 of the cam 15 and moves from the position shown by the solid line to the position shown by the dashed line. The upper end of the door 3 is pushed outward, and the door 3 is opened to the roof 9.
The door 3 is raised upwards without contacting the outer edge of the door 3, and the lower part of the door 3 is finally raised to the pillar 11 at the four points of the lower upper protrusion 8.8 and the lower end protrusion 7.7, as shown in FIG.
The motor 24 is engaged with the hollow part above the vehicle body, and the motor 24 is automatically stopped while the door 3 is securely held in that position, and the door 3 is maintained in a stable state even when most of the door 3 protrudes above the vehicle body.

When closing the door 3, the brake is released by rotating the motor 24 in the reverse direction, and the door 3 descends due to its own weight. When the door 3 reaches the position shown by the dashed line in FIG. 6, the wire 20 is unwound from the drum 23 and descends. In the end, the lower end protrusion 7 is engaged with a cam 15 provided on the floor 12 below the pillar 11, and by this engagement, the lower end of the door 3 is pushed outward using the upper protrusion 8 as a fulcrum. An appropriate closed state is obtained, and the motor is automatically stopped in this state.

Therefore, the door 3 can be opened and closed by completely sliding up and down, which eliminates the need for space for opening and closing the door unlike the conventional pivot type door device, which saves space for parking etc. There is no risk of the car coming into contact with the door, and
It is extremely easy to take people and luggage in and out, and furthermore, at the end of the descent, the upper protrusion 8 is engaged with the cam 15 and the door 3
Since the lower end of the door is pushed outward, the door can be closed properly without the risk of wind and rain getting in.
Since the cam 15 is actuated by the weight of the door 3 and returned by the spring, no wasted power is used, and the structure is simple and can be easily installed in a narrow space of an automobile.

Further, since the door is opened and closed by the electric hoisting device 22, there are various advantages such as no need for labor to open and close the door.

In addition, if a helical spring or the like is attached to the drum 23 of the hoisting device 22 to apply an appropriate force in the hoisting direction to the drum 23, it can be easily raised and lowered by human power. Further, it goes without saying that the above-mentioned door device can be similarly applied to front doors and rear doors, and can also be applied to automobiles for both cargo and passenger use.

As is clear from the above description, the present invention has a special structure in which the door is opened and closed by sliding up and down using a hoisting device, and the door is properly closed and no gaps are formed through which wind and rain can enter. This is of great practical value as an automobile door device that eliminates the drawbacks of conventional pivot type door devices.
