Description

[Detailed description of the invention] Conventionally, when installing a door opening/closing window such as a triangular window in an automobile, as shown in Fig. 1, a mounting bracket b attached to the upper end of the opening/closing glass window a and an upper sash c are fixed to each other. A rotating pin e is inserted between the mounting bracket d and the rotating center axis of the window, and its end is attached, and a screw g is inserted through the lower sash f attached to the lower end of the opening/closing glass window a. The torque of the bullet j interposed between the washer i and the lower sash f is adjusted by screwing the nut h screwed into the door panel k. Therefore, the installation work is troublesome, and there are drawbacks such as the inability to attach the glass to the lower side of the glass a.

This proposal was proposed to eliminate such drawbacks, and includes a housing fixed to one end of the vehicle door glass, a door sash protruding from the door sash corresponding to the fixed position of the housing, and a structure inside the housing. a rotating shaft loosely inserted; at least one washer member co-rotating with the rotating shaft and slidably fitted in the axial direction of the rotating shaft; and a transparent member into which the end of the rotating shaft can be loosely fitted. A bottom cover having a hole formed therein and screwed onto the housing, and a washer member and the housing or the washer that is contracted between the washer member and the bottom cover or between the washer member and the housing. A biasing device that generates a frictional force between the member and the bottom cover, and a bearing that is fixed to the other end of the vehicle door glass and pivoted to a door sash portion facing the door sash portion. The present invention relates to an opening/closing window for a door, characterized in that the frictional force can be adjusted by adjusting the threading distance of the bottom cover.

In this case, as described above, a rotating shaft protruding from the door sash corresponding to the fixed position of the housing is loosely inserted into the housing fixed to one end of the vehicle door glass, and the rotating shaft is coaxially connected to the rotating shaft. At least one washer member is fitted so as to co-rotate and to be slidable in the axial direction, and generates a frictional force between the washer member and a casing or a bottom cover screwed onto the casing. By interposing the machine, the rotating shaft disposed in the door sash, a washer member fitted on the same axis, and an energizing device that generates a frictional force on the washer member are housed in the housing. As a result, the structure can be made compact, and the opening/closing window for the door can be made smaller and lighter.

Further, by adjusting the bottom cover screwed onto the housing, the frictional force of the washer member is adjusted,
The opening/closing force can be adjusted arbitrarily. At this time, since the bottom cover has a through hole into which the end of the rotating shaft can loosely fit, the bottom cover can move forward and backward with respect to the casing without being hindered by the rotating shaft, and the frictional force of the washer member can be adjusted. Furthermore, according to the present invention, a torque load is applied to one of the door sashes, and the torque load is set to 0 on the other sash facing the same door sash, thereby making it possible to make the sash thinner accordingly. The present invention has many advantages, such as the ability to connect other glass windows to the lower part of the commercial window.

The present invention will be described below with reference to the illustrated embodiments.

A is an opening/closing glass for a door, 1 is a housing with an open bottom end, and a rotating shaft 3 fixed to a fixture 2 for an upper door sash B is loosely inserted into the housing 1.
The rotating shaft 3 has a groove (not shown) along the axial direction.
A protrusion (not shown) protruding from the center hole of a pair of upper and lower washer members 4 and 5 fitted on the rotating shaft 3 fits into the groove, and thus each of the washers The members 4 and 5 slide along the axis of rotation 3, but are adapted to rotate together with the axis of rotation 3.
Further, an auxiliary bullet 6 is wound around the rotating shaft 3 between the washer members 4 and 5, and a bottom cover 7 is screwed onto the casing 1 to adjust the torque of the auxiliary bullet 6. has been done. Note that the lower end of the rotating shaft 3 is loosely fitted into the center through hole of the bottom cover 7.

Then, the housing 1 is attached to the upper end of the door opening/closing glass A via the screw 8, a bearing 9 is attached to the lower end of the door opening/closing glass A, and the bearing part of the same bearing 9 is attached to the lower door sash. It is rotatably fitted onto a pin 11 provided upright on the tool 10, and
The fixture 2 is fixed to the upper door sash B, and the door opening/closing glass A is attached to the door sash.

By screwing the bottom cover 7 onto the housing 1 and adjusting the threading distance to the housing 1,
By adjusting the frictional force between the washer members 4 and 5, the opening and closing force can be adjusted as desired.

Figure 4 shows the case where this invention is applied to the triangular window of the front opening/closing door of a car. As mentioned above, the torque load is borne on the upper door sash B, and the torque load on the lower door sash C is 0, so The door sash can be made thinner, a window D that fits in the upper part of the triangular window is provided, and the opening area on the side of the front of the driver's seat is increased, and when the door opening/closing glass A of the triangular window is rotated, This allows the glass to not interfere with maneuvering. In the figure, E indicates the axis of rotation of the door opening/closing glass A, and F indicates the upper and lower opening/closing windows behind the door opening/closing glass A.
