Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a drum casing. More specifically, the present invention relates to a drum casing of a wind regulator drive device.

[Conventional technology]

A window regulator is a device that raises and lowers the window glass of automobiles, etc. Based on Figures 4 and 5,
The basic configuration of the wind regulator (WR) will be explained. 51 is a driven device, and 52 is a driving device.
The driven device 51 includes a carrier 53 for fixing the window glass G and a guide rail 54 for guiding the carrier 53 up and down.
4 is attached inside the door panel D. The drive device 52 includes two wires 5 and 6 connected to a carrier 53 and a drive device main body 57.

The device main body 57 has a drum casing 50 including a drum storage section 58 and a wire guide section 59, and the winding drum 4 placed in the drum storage section 58.
is pivotally supported on the casing 50 by a handle shaft 8. 9 is a handle for rotational operation.

[Problem that the invention attempts to solve]

By the way, in the structure of a general automobile door D as shown in Fig. 4, the sash S and the window glass G are
Since it is inevitable that rainwater or the like will enter the panel through the gap between the drum casing 50 and the drum casing 50, the rainwater or the like may enter the drum casing 50 through the wires 5, 6, etc. In this case, there is a problem in that metal parts such as springs built into the drum casing 50 become rusty.

In view of the above-mentioned circumstances, the present invention aims to provide a drum casing that can prevent the occurrence of rust even if rainwater etc. enters the drum casing.

[Means for solving problems]

The drum casing of the present invention includes a bottomed cylindrical drum storage section that accommodates a wire winding drum, and a wire insertion section for leading out two wires wound around the winding drum. A drum casing for a wind regulator drive device,
It is characterized in that a gutter is formed along the inner circumferential wall of the drum storage part, and a drain hole is further formed in the lower part of the drum storage part.

[Effect]

In the present invention, even if water that has entered the casing through a wire or the like passes through the guide section and enters the drum storage section, it will be guided by the gutter and flowed out from the drain hole at the bottom. Therefore, since water does not enter the center of the casing and adhere to the winding drum, springs, etc., rusting of these parts is prevented.

〔Example〕

Next, embodiments of the present invention will be described.

FIG. 1 relates to one embodiment of the present invention. A perspective view of the drum casing, FIG. 2 is a front view of the drum casing, FIG. 3 is a sectional view taken along line I-I in FIG. 2, and FIG. 4 is a perspective view showing a state in which the wind regulator is attached to the door. , FIG. 5 is a perspective view of the wind regulator drive device.

In Figures 1 and 2, 1 is a drum casing;
2 is a drum storage section, 3 is a wire guide section,
The drum casing 1 is composed of a drum storage section 2 and a wire guide section 3.

The drum storage section 2 is a recess formed in a bottomed cylindrical shape to store a winding drum for wire winding, and is surrounded by a bottom wall 11 and a peripheral wall 12, and a bearing 23 is formed on the bottom wall 11. has been done. Furthermore, a gutter 25 is formed on the bottom wall 11 inside the peripheral wall 12 so as to form a groove 24 .

The wire guide section 3 is a guide member for guiding the two wires 5 and 6 wound around the winding drum, and is connected to the upper semicircular section of the drum storage section 2. This guide portion 3 includes a first guide groove 27 and a first cylindrical portion 28 formed in a groove shape for passing the wire 5 through, and a second guide groove 29 and a second cylindrical portion 30 formed in a groove shape for passing the wire 6 through. consisting of the first
The guide groove 27 and the second guide groove 28 are formed in parallel.

The gutter 25 is formed continuously along the inner surface of the circumferential wall 12 of the drum storage section 2, and forms a groove 24 between the gutter 25 and the circumferential wall 12 for guiding and flowing water. A drain hole 44 is formed above the groove 24 in the lower part of the drum storage section 2.

A drain 41 is formed in the first guide groove 27 and the second guide groove 29, and a weir 42 is formed below the drain 41. The bottom surface 43 of the groove above the drain hole 41 is formed as a slope, so that water can easily flow into the drain hole 41. Further, the weir 42 is also formed to be inclined so that water can easily flow into the drain hole 41.

As shown in FIG. 3, the winding drum 4 is housed in the drum housing portion 2 and the handle shaft 8
The winding drum 4 is supported by a wire guide 31. The wires 5 and 6 are wound around the winding body of the winding drum 4 in opposite directions, and both wires 5 and 6 are passed through the wire guide 3. The conduit 7 of the wire 5 is provided with a cap 31.
The wire 6 is inserted into the first cylindrical portion 28 through a cap and supported by a spring 32. Although not shown in the figure, the wire 6 is also inserted into the second cylindrical portion through a cap and supported by a spring.
0 is the lid of the drum casing 1.

Next, the operation of this embodiment will be explained based on FIGS. 1 and 3. When rainwater entering from the door sash etc. reaches the drum casing 1 through the wires 5, 6 conduit, etc., each cylindrical part 28, 3
It attempts to enter the guide grooves 27 and 29 from 0.
The invading water tries to head toward the drum storage part 2 through the guide grooves 27 and 29, but in many cases, it is blocked by a weir 42 on the way and is discharged to the outside from the drain hole 41.

If there is a lot of intruding water, it may not be possible to block it with the weir 42, but in that case, the intruding water will flow into the gutter 2.
5, the water flows through the groove 24, and is discharged to the outside from the drain hole 44 at the bottom of the casing 1.

Therefore, according to this embodiment, rainwater and the like do not enter into the drum housing section 2 through the gutter 25, so that metal parts such as springs built into the winding drum 4 are prevented from rusting. do not have.

[Effect of idea]

The present invention has a high rust prevention effect because water that attempts to enter the casing can be discharged to the outside.
