Description

[Detailed description of the invention] The present invention relates to door mechanisms for vehicles.

Conventional doors of automobiles, helicopters, airplanes, other practical vehicles, and amusement park vehicles have a mechanism that opens and closes the door outward and laterally through a hinge mechanism around the entrance and exit of the vehicle body. A space is required in which the door can be opened and closed in the side direction.
Furthermore, these doors are composed of two mechanisms: the opening/closing mechanism and the door/window opening/closing mechanism built into the opening/closing mechanism, and there are unavoidable problems such as restrictions on where the door can be opened and closed and the complexity of the mechanism.

In addition, the door was a sliding type in which the door moved parallel to the side of the main body, but in order to provide a window in this type of door, it was necessary to incorporate a door/window opening/closing mechanism, which consisted of two mechanisms. The problem of complexity could not be solved.

In the present invention, the door is configured to be able to rotate in parallel to the opening on the side of the main body around the horizontal axis of the main body and along the opening surface including the opening, that is, the side surface of the main body, and to be able to stop at a desired position. This eliminates the need for a door opening/closing space, and at the same time simplifies the mechanism by combining the conventional door opening/closing mechanism and door window opening/closing mechanism into one mechanism, while retaining the same functions as conventional ones. This is an invention aimed at making it easier.

One side of the main body of an embodiment of the present invention will be described based on a drawing illustrating a one-seater light vehicle. Reference numeral 1 denotes a substantially horizontally cylindrical main body, and a circular opening in the side surface of the vehicle body 1. A rail 4 is laid along the entire periphery of 2. As shown in FIG. 5, the rail 4 has a rectangular upper portion in a longitudinal section, an opening 4a in the lower portion into which the outer peripheral edge 3a of the door 3 can be fitted, and clamping edges 4b, 4b extending around the opening periphery. 5 is a semicircular outer plate covering the rear half of the opening 2, and the outer peripheral edge 5
a is fixed along the outer clamping edge 4b of the rail 4. Reference numeral 3 denotes a transparent or semi-transparent see-through door made of glass or synthetic resin, which is formed in the same semicircular shape as the front half not covered by the outer panel 5 at the opening 2, and has an outer peripheral edge 5a. is a protrusion 3c that fits into the rail 4 and is provided at the center of the inner peripheral edge 3b of the door 3.
and a protrusion 5c provided at the center of the inner circumferential edge 5b of the outer panel 5 are supported by a shaft 8, and the door 3 is guided by the rail 4 around the horizontal axis XX of the vehicle body 1 in the opening 2 and opened. It is mounted so as to rotate parallel to the opening surface including the section 2. Reference numeral 7 designates a mounting plate having a square cross-section with a horizontally bent midway.The upper part 7a, on which the shaft 6a of the knob 6 is screwed, faces the inner clamping edge 4b of the rail 4, and the lower part 7b is fitted with a bolt or the like. It is fixed to the inside of the door 3 by a fastener 9.

In the figure, 10 is a recessed handle formed on the outer surface of the door 3. Reference numeral 11 denotes a nut fixed to the outside of the upper part 7a of the mounting plate 7 in alignment with a hole 7c made in the upper part 7a of the mounting plate 7 in order to screw the shaft 6a of the knob 6 thereinto. In order to allow the door 3 to rotate smoothly along the rail 4, the inner part of the rail 4 is attached to the inside of the rail 4 via a fitting 13 having an H-shaped cross section at both ends of the outer periphery 3a of the door 3 or at multiple points along the way. This is a roller that rotates while contacting the peripheral wall 4c.

In the embodiment, the outer shape of the vehicle body is horizontally cylindrical, and the opening 2 is circular. However, the outer shape of the vehicle body may be other shapes, such as a cubic shape, or The opening 2 may be semicircular with the rear half covered by an outer plate, and in short, the rail 4 may be provided so that the door 3 can rotate parallel to the opening surface including the opening 2 to open and close. Further, the door 3 and the outer panel 5 may have a flat or concave surface other than the convex surface of the embodiment, as long as the door 3 can rotate in parallel to the outer panel 5. In addition, the door 3 is not limited to one piece, but is divided into multiple pieces,
It can also be divided into parts to allow for rotational opening and closing.
Furthermore, the external shape of the door is not limited to the semicircular shape shown in the example, but may also be triangular or polygonal in half. In that case, each vertex of the door slides on the rail, and when it rotates, Gaps that occur between each side of the door and the rail shall be covered by laying a covering plate with an area sufficient to cover the gap along the outer periphery of the rail on the inside or outside of the vehicle and not cause any hindrance to getting on and off the vehicle. .

Since the present invention is configured as described above, when a force is applied to the door 3 from the outside in a clockwise or counterclockwise direction substantially parallel to the door 3, the door 3
The outer peripheral edge 3a of the door 3 is guided by the rail 4 and rotates around the shaft 8 in parallel with the opening surface including the opening 2. When rotated 180 degrees, it overlaps with the outer plate 5 and the front half of the opening 2 is rotated. An entrance/exit is opened, and the driver or user of the vehicle enters the driver's cabin of the vehicle body 1 through the entrance (FIG. 2). After riding, the driver grips the knob 6 and rotates the door 3 around the shaft 8 along the rail 4 again, and when the doorway is closed by the door 3, when the driver tightens the knob 6, the shaft 6a of the knob 6 The tip protrudes from the upper part 7a of the mounting plate 7 and presses the inner clamping edge 4b of the rail 4 toward the door 3, so the outer peripheral edge 3a of the door 3 is clamped between the other clamping edge 4b and prevents rotation. The entrance and exit are closed (Fig. 3).

Next, the driver loosens the knob 6 by turning it in the opposite direction, and releases the pushing force against the outer periphery 3a of the door 3 by separating the tip of the shaft 6a of the knob 6 from the gripping edge 4b, and the door 3 rotates. The door 3 can be opened by grasping the knob 6 and rotating the door 3 by the required circumferential angle.
An opening corresponding to a window hole is formed between the inner circumferential edges 3b and 5b of the outer panel 5, and the driver can stick his neck out through the opening to look outside or ahead (FIG. 4). Further, by grasping the knob 6 and continuing to rotate the door 3, the window hole is enlarged, and by rotating the door 3 by 180 degrees, an opening that can be used as an entrance and exit is created, through which the driver can get on and off the vehicle.

According to the present invention, the door is provided in the opening on the side of the main body of the vehicle so that it can rotate and stop freely about the horizontal axis of the main body and parallel to the opening surface including the opening 2. When opening and closing the car, there is no need for space to open and close the door in the left and right directions of the main body. The door can be opened and closed without any hindrance, allowing users to get on and off, and the door can also be rotated to a desired angle to open a portion of the opening and use it as a window hole, making it easier to open and close the door than a conventional door opening and closing mechanism. The door window opening/closing mechanism becomes a single mechanism that can be used for both purposes, and the mechanism can be simplified. In addition, the knob can be rotated 180 degrees to open the doorway, rotated only at the desired angle to use part of the doorway as a window hole, or closed completely. By tightening, the door is fixed to the rail and its rotation is reliably stopped, so it will not open or close due to vibration or wind pressure while driving, or rotate automatically due to the door's own weight while stopped, making it easy to get in and out of the vehicle. The user's body and hands during the ride or ride,
There is no danger of pinching fingers, face, neck, feet, etc.
Furthermore, by rotating the bottom part of the door to open a window hole on the lower body side of the user, it can also be used as a ventilation hole to let outside air flow into the legs. By partially rotating the , ventilation holes will be opened on the left and right sides of the legs, further improving the ventilation effect inside the main unit, which can be used when the outside temperature is high or when the sunlight is strong and heat tends to build up inside the main unit. The cooling or ventilation function is sufficiently performed, and the vehicle can be moved easily. The opening of the present invention is circular, the rear half of the opening is covered with a semicircular outer plate, and the door is rotated at the center of the opening to open and close, so the entrance is semicircular. Because it is shaped like this, even when it rains, when you open and close the door to go in and out, the raindrops are blocked by the outer panel, so the seats do not get wet.You can also rotate the door a little to partially open the bottom. This allows air to be blown into the vehicle interior, making it possible to circulate air into the vehicle interior even when the vehicle is running in relatively hot and humid conditions, such as during the rainy season, making for smooth driving. Furthermore, this mechanism has a simple structure and can be widely used as a door mechanism for automobiles, helicopters, light airplanes, other practical vehicles, amusement park vehicles, etc.
