Description

The present invention relates to a technique for an elevating device.

Conventionally, as a side window provided on a vehicle door is raised and lowered, the lower end of the side window is supported by a carrier plate, and the driving force of the drive unit is transmitted to the carrier plate via a cable, so that the side window together with the carrier plate is used. There is a known lifting device that raises and lowers the window.
Such an elevating device is generally arranged below the side window and is housed in a space surrounded by an inner door panel and an outer door panel constituting the door of the vehicle.

Here, for a cab-over type vehicle such as a truck, in order to secure a wider view of the vehicle body side as seen from the driver's seat, at least below the side window of the passenger seat side door, the inner side of the door. Some door panels and outer door panels are provided with side view windows.
In such a vehicle, due to space restrictions in the space surrounded by the inner side door panel and the outer side door panel, the elevating device is used, for example, in a region extending from the upper side to the lower side of the side view window. The carrier plate is arranged so as to move up and down adjacent to the end portion (for example, the end portion in the thickness direction of the side view window and the end portion in the direction orthogonal to the moving direction of the carrier plate).
Therefore, for example, when water droplets adhering to the side window enter the inside of the door through a gap between the side window and the inner side door panel or the outer side door panel, the invading water droplets travel along the lower end of the side window and carry the carrier. After reaching the plate and then randomly falling from the lower end of the carrier plate, it may adhere to the side view window and cloud the side view window, which may obstruct the view of the vehicle body from the driver's seat. was there.

Therefore, as a technique for preventing water droplets falling from such a carrier plate from adhering to the side view window, for example, in Patent Document 1, at least one plate surface (front side and / or back side) of the carrier plate is used. A carrier plate provided with a plurality of lateral ribs inclined toward a lower end corner on the front side of the carrier plate (plate surface) is disclosed.

Japanese Unexamined Patent Publication No. 2017-48527

According to the carrier plate in Patent Document 1, the water droplets that reach the carrier plate along the lower end of the side window are once collected at the lower end corner portion on the front side of the carrier plate along the lateral ribs, and then the lower end corner portion. It is possible to prevent water droplets from randomly falling from the lower end of the carrier plate and adhering to the side view window by avoiding the side view window and draining water.
However, since the volume of the water droplets that reach the lateral ribs of the carrier plate is very small, they do not slide down along the lateral ribs due to their own weight, but stay in place due to the influence of surface tension and temporarily remain. In such a case, for example, due to an impact caused by starting or stopping the vehicle, water droplets may suddenly drop randomly from the lateral ribs and adhere to the side view window.

An object of the present invention is to provide an elevating device capable of reliably guiding water droplets adhering to either the front surface or the back surface of a side window to a predetermined side of a carrier plate and draining the water droplets.

In the side door 101 in the open state, the entire plate surface of the side window W may be completely stored in the storage portion 104 of the side door 101 as in the present embodiment, and the side window may be completely stored. A part of the plate surface of W may be stored in the storage portion 104, and the remaining part may be left in the opening 102.

By the way, the side door 101 in the present embodiment is, for example, a side door provided in a cab-over type vehicle such as a truck, and below the opening 102, the field of view of the vehicle body side as seen from the driver's seat is wider. A side view window Wa is provided to ensure this.
Further, in order to secure a space portion in the side door 101 (that is, a space portion surrounded by the inner side door panel and the outer side door panel constituting the side door 101), the lower end of the side window W is from the rear end side to the front end. It is formed so as to incline downward toward the side.
That is, the lower end of the side window W has an inclined portion W1 that inclines downward toward the first carrier plate 20A side arranged at one end (front end) of the lower end.
