Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention is a window of an automobile in which a window hole is opened and closed by raising and lowering a glass plate, and the glass plate does not descend below a certain height when the window is opened. The present invention relates to a vehicle window opening / closing device that can be locked.

Problems to be Solved by Conventional Techniques and Inventions In an automobile window in which a window hole at an upper part of a door is opened and closed by raising and lowering a glass plate, when the glass plate is lowered to open the window, If the height to the upper edge of the glass plate is low, there is a risk that an infant standing on the seat will lean out of the car, hit a sign, etc., or fall out of the car. There is a demand for a device that can be regulated so that it does not descend below the height of.

Means for Solving the Problems As a means for solving the above problems, the present invention rotatably supports a rotating plate that rotates with the movement of a geared cable on a base body, and A spiral groove is concentrically formed, and a movable pin that engages with the spiral groove and a long groove in the radial direction formed on the rotating plate is slidably relatively provided, and the movable pin projects on the moving path of the movable pin. By engaging with the lock plate to prevent rotation of the rotary plate in the window opening direction and allowing rotation of the rotary plate in the window closing direction, and by retracting from the moving path of the movable pin, the rotary plate can be opened and closed in both directions. The stopper is provided to move between the lock release position and the lock release position.

The operation and effect of the present invention With the above-mentioned structure, when the geared cable is moved in the axial direction by the rotation of the drive gear, the glass plate moves up and down and the rotary plate rotates, and with the rotation of the rotary plate, The movable pin moves in the circumferential direction along the spiral groove while moving away from or close to the center of rotation of the rotating plate, and when the stopper is moved to the unlocked position, it can be opened and closed in both directions. Since the rotation of the window is allowed, the glass plate can be lowered to the maximum lowered position when the window is opened, and the height from the seat to the upper edge of the glass plate should be lowered to open the window wide. In addition, when the stopper is moved to the lock position, when the window is opened, the movable pin engages with the stopper before the glass plate reaches the maximum lowered position. Since the rotation in the opposite direction is blocked, the movement of the geared cable and the lowering of the glass plate are stopped, and the glass plate is held unmovable in the half open state where the height of its upper edge is sufficiently high from the seat. , It has the effect of preventing the infant from leaning out of the car through the window when standing up on the seat.In this locked state, rotation of the rotating plate in the window closing direction is allowed. Therefore, the glass plate can be freely opened and closed between the half open state and the fully closed state.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In a door 1 shown in FIG. 1, a glass plate 3 guided by a pair of front and rear guides 2 and 2 rises and a window hole 4 in an upper portion of the door 1 is installed.
Closed position to close the door and the lower part of the door 1 to the hollow 5
The glass plate 3 is mounted so as to be freely movable between it and the fully open position where the entire surface of the window hole 4 is opened, and is integrated with the glass plate 3 via a support member 6 that supports its lower edge. Geared cable 8 connected so that it can be moved to
Is slidably inserted into a vertical guide tube 9 and an oblique conduit 10 which are piped in the hollow 5 of the door 1 and whose upper ends are smoothly connected to each other. An opening / closing drive unit 15 for lifting and lowering the plate 3 is attached.

This opening / closing drive unit 15 is, as shown in FIGS. 2 to 4, a base 1 fixed to a conduit 10 by casting.
6, a drive mechanism 18 and a stopper mechanism 3 which will be described in detail later.
0 and the base body 16 are screwed into their screw holes 17
It is fixed to the inner panel 1a of the door 1 by screwing a bolt (not shown) on the drive mechanism 18
When the handle 22 is fitted to the selesion shaft portion 21 protruding from the inner panel 1a of the drive shaft 20 into the vehicle and the drive shaft 20 is rotated by the manual operation, the rotational force of the handle 22 is transmitted through the irreversible clutch 23 to the drive gear. Transmitted to 25,
With the rotation of the drive gear 25 in the direction of the arrow in FIG. 2, the geared cable 8 also slides in the direction of the arrow, so that the glass plate 3 is lowered and the window hole 4 is opened. At the same time, the reverse rotation of the drive gear 24 raises the glass plate 3 to close the window hole 4, and the glass plate 3 receives an external force to move the glass plate 3 up and down. Therefore, even if the external force is transmitted to the drive gear 25 via the geared cable 8, the rotation of the drive gear 25 is locked by the nonreciprocal clutch 23 and the glass plate 3 is prevented from moving up and down. I'm running.

The stopper mechanism 30 includes a rotary plate 31 in which meshing teeth 32 formed on a circular outer periphery are meshed with a drive gear 25, and a central hole 33 having two parallel surfaces 35, 35 formed in a rotary shaft 34.
Is rotatably supported on the base body 16 by being fitted integrally rotatably to the base body 16, and the semicircular portion 36 at one end of the rotary shaft 34 is provided with a rotating window 31 in a window opening direction indicated by an arrow in FIG. A spiral spring 37 is attached to the cover 38 attached to the base body 16 so as to balance the operating force at the time of opening the window and the operating force at the time of closing the window by elastically contracting in accordance with the rotation. It is housed.

The rotary plate 31 is provided with a long groove 40 extending in the radial direction from the center of rotation thereof. On the other hand, a spiral groove 43 is formed on a surface of the base 16 which is parallel to the rotary plate 31 and has a gap S therebetween. Further, in the gap S, the movable pin 44 is mounted by fitting the reduced diameter portions 45, 45 at both ends thereof into the spiral groove 43 and the long groove 40 so as to be relatively slidable relative to each other. The movable pin 44 is guided by the long groove 40 of the rotary plate 31 as the rotary plate 31 rotates in the window opening direction shown by the arrow in FIG. Along the way, it gradually moves in the circumferential direction from the center toward the outer peripheral side.

In addition, the base body 16 includes an L-shaped plate-like stopper 50.
However, the torsion coil spring 5 fitted to the support shaft 51 is swingable around the support shaft 51 penetrating the base end thereof.
The stopper 50 is supported in a state of being urged in the clockwise direction in FIG. 2 by the elastic force of 2, and the stopper 50 has a side end portion 1b of the door 1 via a wire 54 having one end connected to a bent portion thereof.
Freely swinging around the shaft 56 and the tension coil spring 5
It is connected to a lever 55 mounted so as to be held in two tilted postures by the elastic force of 7. When the lever 55 is tilted in a direction in which the wire 54 can move to the stopper 50 side, the stopper 50 twists. The rocking force of the coil spring 52 causes it to oscillate in the clockwise direction in FIG. 2 so that the engaging portion 50a at the tip is retracted from the gap S between the rotary plate 31 and the spiral groove 43, as shown by the chain line in FIG. While being held in the released state, when the lever 55 is tilted to the opposite side, the stopper 50 is pulled by the wire 54 against the elastic force of the torsion coil spring 52, so that It swings counterclockwise in Fig. 2 and, as shown by the solid line in Fig. 2,
The movable pin 4 along the spiral groove 43 is caused to enter the contact portion 50a of the base body 16 and prevent the swinging thereof from moving into the gap S from the notch portion 16a of the base body 16 in a state in which the swing is blocked.
It is adapted to be held in a locked state in which the movement path of No. 4 is blocked from the outer peripheral side to the middle.

The present embodiment has the above-described configuration, and when the stopper 50 is in the unlocked state, the engaging portion 50a is retracted outside the gap S, so that the movement of the movable pin 44 is not obstructed during the opening / closing operation. The glass plate 3 can be freely moved up and down between a fully closed state in which the window hole 4 is completely covered and a fully opened state in which the entire surface of the window hole 4 is opened, and the opening degree of the window hole 4 can be arbitrarily adjusted. it can.

Further, when the stopper 50 is brought into the locked state, the engaging portion 50a at the tip of the stopper 50 enters into the gap S to block the movement path of the movable pin 44, and therefore the movable pin 44 is moved by lowering the glass plate 3. When it is moved from the center side of the spiral groove 43 toward the outer peripheral side, when the lower half of the glass plate 3 is hidden in the hollow 5 of the door 1 and is in a half open state, the movable pin 44 is attached to the engaging portion 50a of the stopper 50. Contact with each other, which prevents rotation of the rotary plate 31 and the drive gear 25 and sliding of the geared cable 8, so that the upper edge of the glass plate 3 is positioned sufficiently higher than a seat (not shown). It is locked so that it cannot be lowered to the half-opened state, so that even if the infant stands up on the seat, the face and hands cannot be put out of the window and the infant's safety is secured. In this lock state Te is the spiral groove 43 of the movable pin 44
Since the movement toward the center of the window in the window closing direction is allowed, the opening of the window hole 4 can be adjusted by freely moving the glass plate 3 up and down between the half open state and the fully closed state.

In addition, when the stopper 50 is locked when the glass plate 3 is lower than the half-open state, when the glass plate 3 is lifted, the movable pin 4 contacted with the tip of the stopper 50.
4 is a stopper 5 against the elasticity of the torsion coil spring 52.
Since 0 can be moved along the spiral groove 43 while swinging 0 in the clockwise direction in FIG. 2, it is possible to close the window,
After that, when the window is opened again, the movable pin 44 is moved to the stopper 5.
The glass plate 3 is engaged with the glass plate 3 and is prevented from moving.
Is locked in a half open state.

In this embodiment, the drive mechanism 18 and the stopper mechanism 30 are used.
Since and are unitized by attaching to the common base body 16, there is an advantage that both mechanisms 18 and 30 can be simultaneously assembled to the door 1 only by the work of fixing the base body 16 to the inner panel 1a.

In the above embodiment, the glass plate 3 is moved up and down by the manual operation of the handle 22, but the present invention is also applied to a power window in which the glass plate 3 is moved up and down by driving an electric motor. In this case, the stopper 50 may be locked and unlocked by remote control from the driver's seat.

FIG. 5 shows a modification 60 of the opening / closing drive unit 15.
The rotary plate 61 and the drive gear 62 are supported at positions separated from each other on the base body 63, and meshing teeth 65 having the same shape as the drive gear 62 are formed on the outer periphery of the rotary plate 61. The rotary plate 61 is directly connected to the geared cable 8 by engaging the meshing teeth 65 thereof.
