Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile window opening/closing device in which a cable for transmitting operating force, such as a geared cable, is run by manual rotation of an opening/closing handle or driven by a motor, thereby raising and lowering a window panel.

Conventionally, in this type of opening/closing device, a guide conduit is arranged parallel to the guide groove of the window frame into which both side edges of the window plate fit, and the cable is run within the conduit. A connector of the cable is protruded from an open groove extending in the axial direction of the road, and an elevator receiver is connected to the connector, and a fitting groove is formed at the upper edge of the elevator receiver, and a fitting groove is formed at the lower edge of the window plate. is fitted into the groove to support the load, and as the cable travels back and forth, the window plate is moved up and down by following the up-and-down receiver to open and close the window.

However, due to installation errors and the like, it is difficult to make the guide conduit and the guide groove precisely parallel to each other, and for this reason, as the window frame moves up and down, slight movement occurs in the front and rear directions relative to the up and down receiver. Although this slight movement is allowed by the sliding movement between the lower edge of the window frame and the fitting groove, this sliding resistance may impede smooth rotation of the handle or place a large load on the motor drive. In addition, noise is generated between the lower edge of the window frame and the fitting groove as it moves up and down, making the opening and closing operations unpleasant. In addition, since it is difficult to precisely match the guide pipe and the guide groove in the inside and outside directions of the door, the lower edge of the window frame may move in that direction relative to the pipe.
In this case, the conduit is curved, which puts a burden on the opening/closing operation as described above.

In view of the above-mentioned points, the present invention aims to provide an automobile window opening/closing device that can reduce the sliding resistance between the fitting groove and the lower edge of the window plate and the generation of noise.

An embodiment of the invention will be described with reference to the accompanying drawings.

FIG. 1 shows an outline of the device of the present invention, in which an automobile door 1 is provided with a window frame 2 including two parallel edges 2a and 2b facing each other in the front and rear direction. The window is opened and closed by fitting the front and rear edges into guide grooves 3 formed in the two edges 2a and 2b and sliding the window plate 4.

A rectangular inner surface plate 5 is fitted inside the edges 2a and 2b and joined to the inside of the door 1, and studs protruding inward are provided in the mounting gap created between the outer wall 6 of the door 1 and the outer wall 6 of the door 1. A transfer device 8 screwed onto the inner surface plate 5 by bolts 7, 7 is accommodated. A gear is housed inside the transfer device 8, and an opening/closing handle 9 is fixed to a rotating shaft of the gear that projects inside the inner surface plate 5.

Inside the transfer device 8, there is a geared cable 12, which is made up of metal wires 11, which serve as meshing teeth, helically wound at equal pitches around a core wire 10 made of a large number of stranded metal wires as shown in FIG. The cable 12 is inserted into the inside of the inner surface plate 5 by the attachment pieces 14, 14 as the opening/closing handle 9 rotates due to the engagement between the gear in the transfer device 8 and the metal wire 11. It runs within a supported conduit 15.
A guide conduit 16 parallel to the guide groove 3 is formed between the attachment pieces 14 and 14 of the conduit 15, and the geared cable 12 runs parallel to the guide groove 3 within the guide conduit 16. In addition, a non-reversible clutch is fitted onto the rotating shaft within the transfer device 8,
The geared cable 12 cannot be moved unless the opening/closing handle 9 is rotated, and even if the window plate 4 is pushed downward by placing a hand on the top of the slightly open window plate 4, the geared cable 12 is locked and its movement is prevented. This makes it impossible to open the window plate 4 by such an operation.

2 and 3 show essential parts of the present invention, in which a vertically long open groove 17 is formed along the axial direction on the outside of the guide conduit 16, and inside the guide conduit 16 of the geared cable 12. is provided with an engaging element 18 having a fitting piece 19 protruding from the open groove 17.

At a position facing the open groove 17 of the guide conduit 16, there is disposed a T-shaped elevating body 20, which has elongated holes 24, 24 formed in the front and rear directions on both sides thereof, and has protrusions above and below. Rectangular fitting grooves 21, 21
The guide pipe 16 is fitted into the slippery occluded circular guide grooves 22a, 22a of the sliding guide pieces 22, 22 made of synthetic resin fixed to A connecting groove 23 in the vertical direction formed between the fitting grooves 21 and 21
The fitting piece 19 fits inside and is connected to the engaging element 18. The above-mentioned attachment is easily performed by pressing the guide pipe 16 from the front surface of the elevating body 20 by utilizing the deflection of the guide pipe 16. As the engaging element 18 moves up and down as the geared cable 12 travels, the elevating body 20 moves up and down using the guide pipe 16 as a guide.

A receiving member 30 having a substantially Y-shaped cross section is disposed on the outside of the elevating body 20, and the lower edge 4a of the window plate 4 is inserted into the fitting groove 31 formed in the upper part of the receiving member 30. It's almost a tight fit. Further, the long hole 2 of the receiver 30
Screw holes 32, 32 are formed at positions corresponding to 4 on the left and right.

Connecting rods 34, 34 provided with hexagonal locking heads 35 are inserted through the elongated holes 24, 24 of the elevating body 20,
The screws at the tips thereof are screwed into the screw holes 32, 32. By tightening the connecting rod 34, a flange 36a at the tip is attached to the outer periphery of the connecting rod 34.
A cylindrical piece 36 pressed toward the receiver 30 is fitted on the outside of the cylindrical piece 36, and a spring receiving seat piece 37 is fitted onto the cylindrical piece 36. The seat piece 37 has a sliding portion 38 having a diameter approximately equal to the width of the elongated hole 24 formed at its outer end, and a seat 39 having an annular groove formed on the inside around the sliding portion 38 . The sliding portion is fitted into the elongated hole 24. Furthermore, the connecting rod 3
4 is fitted with an annular seat plate 40 that contacts the locking head 35, and a spring 4 is fitted between the catch seat 39 and the annular seat plate 40.
1 is attached. Due to the action of this spring 41, the outer surface of the seat 39 comes into contact with the circumference of the elongated hole 24, and the elevating body 20 and the receiver 30 are urged in the approaching direction. Therefore, the elevating body 20 and the receiving body 30 are pressed into contact and connected via the collar 36a.

Next, the operation of this embodiment will be explained.

When the opening/closing handle 9 is rotated, the geared cable 12 runs due to the feeding operation of the metal wire 11 by the gear in the transfer device 8, and the elevating body 20 is raised and lowered as the engaging element 18 is raised and lowered, and the elevating body 20
The receiver 30 connected to the window plate 4 follows this, and the window plate 4
guides the guide groove 3 and moves up and down. At this time, if the parallelism between the guide groove 3 and the guide conduit 16 is not uniform in the front and back, the window plate 4 moves in the front and rear direction as it moves up and down. When this movement occurs, the elevating body 20 and the receiver 30 are only pressed together by the biasing force of the spring 41, so the receiver 30 moves through the elongated hole 24 while being biased by the spring 41.
Move back and forth within. Therefore, almost no sliding occurs between the fitting groove 31 and the lower edge 4a, and the generation of sliding resistance and noise is significantly reduced.

Further, when the guide groove 3 and the guide pipe 16 are not aligned in the inner and outer directions of the door 1, the lower edge 4a slightly moves in that direction with respect to the guide pipe 16, but this outward movement When , receptor 3
The connecting rod 34 screwed into the rod 34 moves in the direction of the arrow in FIG. Therefore, the guide pipe 16 will not be curved.

In the embodiment described above, the geared cable 12 was used, but any cable that runs within the guide conduit 16 may be used.

Further, the elongated hole 24 is formed on the receiver 30 side, the connecting rod 34 is passed through the elongated hole 24 from the outside of the receiver 30 and its end is fixed to the elevating body 20, and the locking head 35 is fixed to the elevating body 20.
A spring 41 may be attached between the receiver 30 and the receiver 30.

Furthermore, the cylinder piece 34 is not necessarily necessary, and any structure may be used as long as the spring 41 biases the elevating body 20 and the receiving body 30 in the approaching direction.

As clarified by the above description, the present invention provides for guiding the inside of the guide pipe from an open groove along the axial direction of the guide pipe arranged parallel to the guide groove into which both side edges of the window plate are fitted. A connector of the running cable is projected, an elevating body is connected to the connector, a receiver is fitted to the lower edge of the window plate, and either the elevating body or the receiver has a length in the front and rear direction. A hole is formed, a connecting rod with a locking head is inserted through the elongated hole, the end thereof is fixed to either the elevating body or the receiver, and the peripheral portion of the elongated hole is inserted from the insertion side of the connecting rod. A spring catch piece that abuts on the connecting rod is fitted onto the connecting rod, and a spring is attached between the locking head of the connecting rod and the catch piece to connect the elevating body and the receiver. The receiver can be moved in the front-back direction and the inner-outside direction with respect to the elevating body, and even if the guide pipe is not arranged evenly with respect to the guide groove of the window frame, the lower edge of the window plate can be moved. This prevents as much as possible the occurrence of sliding resistance and noise between the fitting groove and the lower edge of the window plate due to the movement of the receiver due to the slight movement of the window plate, and allows the window plate to open and close smoothly. It has excellent effects such as:
