Description

  The present invention relates to a vehicle window sash.

  Conventionally, a sash has been provided in the opening, and the sash that supports the lower end of the shoji that opens and closes by opening the opening has been provided with a groove that opens to the window glass side and extends along the sliding direction of the shoji. The rainwater that flows in is discharged through a drain hole formed in the bottom surface of the groove. The drainage hole communicates with a drainage passage having an external communication hole that opens to the outside, and rainwater and the like accumulated in the groove are discharged from the sash through the drainage hole. By the way, since the drainage passage communicates with the outdoor side, when the indoor atmospheric pressure becomes lower than the outdoor atmospheric pressure, air flows into the room (backflow) through the drainage hole formed in the indoor groove. At this time, if rainwater or the like is present in the drainage passage, rainwater may enter the room together with air. Therefore, the sash is provided with a drain valve that opens and closes a drain hole in accordance with a pressure difference between the inside and the outside (for example, Patent Document 1).

  Further, as shown in FIGS. 6A and 6B, there is a sash (vehicle window sash) 101 disposed in an opening (window) of a vehicle (for example, a bus, a train, a one-box car, etc.). . The sash 101 is formed on the sash portion 103 that supports the lower end portions of the window glasses 102a and 102b, and on the side opposite to the window glass (lower side in the illustrated state) of the sash portion 103, as shown in FIG. 6 (a). And a frame portion 104 that is fixed to a rail (not shown) that extends in the depth direction in the drawing.

  The sash portion 103 is provided with a glass run 105 for guiding the window glasses 102a and 102b on the window glass side (upper side in the illustrated state), and on the non-window glass side (lower side in the illustrated state) the sash portion 103 and the frame. A substantially hollow drainage passage 106 is formed by the portion 104. The sash portion 103 is formed with a drain hole 107 that communicates the window glass side of the sash portion 103 with the drain passage 106, and the glass run 105 is formed with a hole 108 that surrounds the drain hole 107. The drainage passage 106 includes an external communication hole 109 that communicates with the outside of the vehicle, and rainwater and the like accumulated in the sash portion 103 is discharged from the vehicle through the drainage hole 107 and the drainage passage 106 without overflowing from the sash portion 103.

As shown in FIG. 6B, the drain valve 110 includes a valve portion 111 that swings according to a pressure difference inside and outside the vehicle interior, and a fixed portion 112 that is formed integrally with the valve portion 111 and is fixed to the sash 101. And is composed of. The fixing portion 112 is fixed to the drainage passage side of the drainage hole 107 together with the valve portion 111. When the air pressure inside the vehicle compartment becomes lower than the air pressure outside the vehicle interior, the valve portion 111 moves to the vehicle interior side and closes the drain hole.
JP 2003-314158 A

  However, the fixed portion 112 of the conventional drain valve 110 is disposed on the side opposite to the window glass of the sash portion 103 together with the valve portion 111. Since the frame portion 104 that forms the drainage passage is disposed on the side of the sash portion 103 opposite to the window glass, the frame portion 104 is disposed on the side of the sash portion 103 opposite to the window glass (the drainage passage is formed). Before) the drain valve 110 must be fixed. Therefore, the sash portion 103 and the frame portion 104 of the sash 101 need to be formed of different members, and the members (for example, screws 113) for forming the sash 101 increase, which is required for assembly hole processing.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings.
FIG. 1A illustrates a vehicle window sash 1 that is disposed in an opening (hereinafter referred to as a window) of a vehicle (not shown) and supports a window glass that closes or opens and closes by opening the vehicle. FIG. 1B is a cross-sectional view taken along the line AA of FIG. 1A.

  As shown in FIG. 1 (a), a vehicle window sash 1 is made of a light alloy extruded material and is composed of an upper sash 1a and a lower sash 1b extending in the horizontal direction and two vertical sashes 1c and 1d extending in the vertical direction. It is fixed to an opening of a vehicle (not shown). Both ends of a horizontal sash 1e extending in a horizontal direction (that is, a direction parallel to the longitudinal direction of the lower sash 1b) are fixed to the vertical sashes 1c and 1d, and between the horizontal sash 1e of the opening and the upper sash 1a. Is closed by a single window glass 2, and the opening and closing of the lateral sash 1e and the lower sash 1b are opened and closed by two window glasses 3a and 3b. In the present embodiment, the lower sash 1b of the vehicle window sash 1 is a sash that slidably supports the lower end of the window glass.

  Next, the sash 1b will be described in detail. As shown in FIG. 1B, the sash 1b is formed in a substantially hollow shape extending in the sliding direction of the window glasses 3a, 3b, and a sash portion 10 that supports the lower ends of the window glasses 3a, 3b, and a vehicle ( And a frame portion 20 that is fixed to an unillustrated frame. In FIG. 1B, the upper side is the window glass side and the lower side is the anti-window glass side.

  The sash portion 10 is formed on the window glass side of the sash 1b, and is formed with two grooves 11a and 11b extending along the longitudinal direction of the sash 1b. The window glasses 3a and 3b are guided in the grooves 11a and 11b. A glass run 4 is accommodated. The first window glass 3a is supported by a first groove 11a disposed on the vehicle interior side, and the second window glass 3b is supported by a second groove 11b disposed on the outside of the vehicle. The window is opened and closed by moving the first window glass 3a and the second window glass 3b in a sliding manner along the first groove 11a and the second groove 11b, respectively.

  The frame portion 20 is formed integrally with the sash portion 10 on the anti-window glass side of the sash 1b, and includes a facing surface 21 that faces an opening of the vehicle (not shown) and an extending surface 22 that extends to the anti-window glass side. The opposing surface 21 and the extending surface 22 extend along the longitudinal direction of the sash 1b. The sash 1b is positioned and fixed with respect to a vehicle (not shown) by the facing surface 21 and the extending surface 22.

  A drain hole 13 is formed in the bottom portion 12 of the first groove 11 a of the sash portion 10, and the first groove 11 a of the sash portion 10 and the hollow portion 30 of the sash 1 b are communicated by the drain hole 13. In addition, an external communication hole 31 that communicates the outside of the vehicle and the hollow portion 30 is formed on the surface of the sash 1b on the vehicle outer side. That is, the hollow portion of the sash 1b becomes the drainage passage 30, the bottom surface 12a of the first groove 11a of the sash portion 10 becomes the first surface (the bottom surface of the sash portion 10) 12a disposed on the window glass side, and the sash portion 10 The surface 12b which is the surface on the side opposite to the window glass and forms the drainage passage 30 is the second surface 12b disposed on the drainage passage 30 side. Water accumulated on the window glass side of the sash portion 10 flows into the drainage passage 30 through the drainage hole 13 and is discharged outside the vehicle. A hole 4b is formed in the bottom 4a of the glass run 4 at a position corresponding to the drain hole 13, so that water accumulated in the first groove 11a (glass run 4) is not obstructed by the glass run 4 and the drain passage 30. (See FIG. 3).

  By the way, since the drainage passage 30 communicates with the outside of the passenger compartment, when the atmospheric pressure in the passenger compartment becomes lower than that outside the passenger compartment, air flows into the passenger compartment through the drain holes 13 (backflow). At this time, if water or the like is present in the drainage passage, there is a risk of entering the vehicle compartment together with air. Accordingly, the sash portion 10 is provided with a drain valve 40 to prevent air from flowing backward from the drain hole 13.

  Next, the drain valve 40 will be described in detail. 2 is a side view of the lower sash 1b as viewed from the arrow B in FIG. 1B, FIG. 3 is a sectional view taken along the line CC in FIG. 2, and FIG. 4 is a side view of the drain valve 40.

And a connecting portion 43 that is inserted through the working hole 14 formed in the sash portion 10 and connects the valve portion 41 and the fixing portion 42. The drain valve 40 is formed, for example, by pressing a plate-like member made of plastic resin.

  As shown in FIG. 2, the working hole 14 is arranged along the drain hole 13 along the longitudinal direction of the sash 1 b (the left-right direction in the state shown in FIG. 2), penetrates the bottom 12 of the sash part 10, and the groove 11 a and the drain passage. 30. In addition, the diameter D1 of the work hole 14 is larger than the diameter D of the drain hole 13.

  The valve portion 41 is formed in a substantially plate shape whose thickness direction is the height direction of the first groove 11a of the sash portion 10 (the vertical direction in the state shown in FIG. 3). Further, the width W1 of the valve portion 41 is formed to be smaller than the diameter D1 of the work hole 14 and larger than the diameter D of the drain hole 13. The valve part 41 contacts the sash part 10 and closes the drain hole 13 when the first surface side of the drain hole 13 has a lower pressure than the second surface side.

  The fixing portion 42 is formed in a substantially plate shape whose thickness direction is the height direction of the first groove 11a of the sash portion 10 (vertical direction in the state shown in FIG. 3), and extends along the longitudinal direction of the first groove 11a. The working hole 14 has a width W2 larger than the diameter D1. Further, the width W2 of the fixed portion 42 is determined according to the width W of the first groove 11a, and the movement of the fixed portion 42 in the width direction of the first groove 11a is restricted. That is, the rotation of the fixed portion 42 around the work hole 14 is restricted. Further, the width W2 of the fixed portion 42 is formed to be larger than the diameter D1 of the work hole 14.

  As shown in FIG. 4, the connecting portion 43 has a width W3 smaller than the diameter D1 of the working hole 14 (see FIG. 2), and extends along the plate thickness direction of the sash portion 10 (vertical direction in the state shown in FIG. 4). The first connecting portion 43a extending and penetrating the working hole 14 and the second connecting portion 43b asymptotically approaching the window glass side from the opposite end portion of the first connecting portion 43a on the window glass side. In FIG. 4, the vertical direction in the state shown in FIG. 4 is the plate thickness direction of the sash portion 10.

  The window glass side end portion of the first connecting portion 43a is formed integrally with the end portion of the fixing portion 42, and the fixing portion 42 extends in a direction substantially perpendicular to the first connecting portion 43a. The distal end portion of the second connecting portion 43b is formed integrally with the end portion of the valve portion 41, and the valve portion 41 extends along the extending direction of the second connecting portion 43b.

  Further, in the thickness direction of the sash portion 10 (vertical direction in the state shown in FIG. 4), the distance L from the tip of the second connecting portion 43b to the surface 42a on the side opposite to the window glass of the fixing portion 42 is It is formed to be smaller than the thickness H of the bottom portion 12. Therefore, when the drain valve 40 is fixed to the sash portion 10, as shown in FIG. 3, the surface 10a on the side opposite to the window glass of the sash portion 10 and the surface 43c on the window glass side of the second connecting portion 43b come into contact with each other. The second connecting portion 43b is curved in such a manner that it is pushed back by the sash portion 10. The valve portion 41 is urged toward the sash portion 10 by an elastic force that resists the bending of the connecting portion 43.

In addition, the valve part 41 is formed thinly so that it may move to the anti-window glass side against the urging force by the second connecting part 43b due to the weight of water in the first groove 11a.
Further, the fixed portion 42 and the valve portion 41 extend from the connecting portion 43 in opposite directions in the longitudinal direction of the sash 1b (the left-right direction in the state shown in FIG. 2), and the connecting portion 43 extends in the longitudinal direction of the sash 1b. 41 and the fixed portion 42.

  Further, a convex portion 42b is integrally formed on the surface 42a of the fixed portion 42 on the side opposite to the window glass. The convex part 42b protrudes from the fixed part 42 to the anti-window glass side. When the fixed part 42 is fixed to the bottom part 12 of the first groove 11a, it is accommodated in the drain hole 13 together with the connecting part 43 (second connecting part 43b). Is done. The convex portion 42 b and the connecting portion 43 abut against the surface 14 a forming the work hole 14, and the fixed portion 42 is restricted from moving in the longitudinal direction of the sash 1 b by the convex portion 42 b and the connecting portion 43.

Next, the assembly procedure of the drain valve 40 will be briefly described with reference to FIG.
First, the valve portion 41 and the second connecting portion 43b of the drain valve 40 are inserted into the drain passage 30 side from the window glass side of the working hole 14 (FIG. 5A). At this time, since the width W2 of the fixing portion 42 is formed larger than the diameter D1 of the work hole 14, the drain valve 40 is prevented from falling off from the work hole 14. Next, the fixing portion 42 is tilted to the side where the drainage hole 13 is not formed in the longitudinal direction of the first groove 11a (left side in the illustrated state of FIG. 5B), and the surface 42a on the side opposite to the window glass of the fixing portion 42 is placed. It is made to contact | abut to the bottom face 12a of the bottom part 12 of the 1st groove | channel 11a (FIG.5 (b)). At this time, the fixing portion 42 is fixed so that the convex portion 42 b formed on the surface 42 a on the side opposite to the window glass of the fixing portion 42 is accommodated in the work hole 14 together with the connecting portion 43. At this time, the fixing portion 42 may be fixed to the bottom surface of the first groove 11a by adhesion. Next, the glass run 4 is accommodated in the first groove 11a and the work hole 14 is closed (see FIG. 1B). That is, the fixing portion 42 is fixed by being sandwiched between the glass run 4 and the sash portion 10, and the work hole 14 is closed by the glass run 4 (see FIG. 1B).

As described above, according to the present embodiment, the following effects are obtained.
(1) When the drain valve 40 (connecting portion 43) is inserted into the work hole 14, the fixing portion 42 of the drain valve 40 is disposed on the window glass side of the sash 1b, and the valve portion 41 of the drain valve 40 is drained. It is disposed on the drainage passage side of the hole 13. Therefore, the drain valve 40 can be fixed from the window glass side of the sash portion 10. Moreover, the sash 1b in which the sash portion 10 and the frame portion 20 are integrally formed can be obtained by using the drain valve 40 having such a configuration.

  (2) The work holes 14 arranged in parallel with the drain holes 13 are closed by the glass run 4. Therefore, air is prevented from flowing into the vehicle compartment from the working hole 14 (reversely flowing) without using a special member. Further, since the glass run 4 is a member for guiding the window glasses 3a and 3b, a member for closing the work hole 14 is not necessary, and an increase in the number of members is hindered.

  (3) Since the diameter D1 of the work hole 14 is formed larger than the diameter D of the drain hole 13, the valve portion 41 having a width W1 larger than the diameter D of the drain hole 13 is disposed on the second surface side. be able to. Then, the drain hole 13 can be completely closed by the valve portion 41 having a width W1 larger than the drain hole 13.

  (4) Since the fixing portion 42 of the drain valve 40 has a width W2 corresponding to the groove 11a of the sash portion 10, the fixing portion 42 serves as a positioning portion that restricts the movement of the drain valve 40 in the width direction of the groove 11a. The rotation of the drain valve 40 around 43 (work hole 14) is hindered. Therefore, the drain valve 40 can be easily fixed to the sash 1b. Moreover, since the fixing | fixed part 42 is arrange | positioned at the window glass side of the sash part 10, the valve part 41 arrange | positioned at the anti-window glass side can be positioned from the window glass side.

  (5) When the convex portion 42b is inserted into the work hole 14, the movement of the drain valve 40 in the longitudinal direction of the sash 1b is restricted. That is, the convex portion 42b becomes a positioning portion that restricts the movement of the drain valve 40 in the longitudinal direction of the sash 1b, and the positioning of the drain valve 40 becomes easy.

  (6) Since the valve part 41 is thinner than the connection part 43, it is easy to separate from the sash 1b by the atmospheric pressure change and the weight of the water accumulated on the sash 1b. Moreover, since the valve part 41 is urged | biased by the connection part 43 to the sash side, possibility that the valve part 41 will space apart from the sash 1b and the opening and closing of the drain hole 13 will be reduced is reduced. That is, since the valve portion and the connecting portion are different in thickness, the function of the drainage valve (prevention of backflow due to atmospheric pressure change and discharge of water present in the sash) is improved.

In addition, you may change embodiment of this invention as follows.
In the above-described embodiment, the fixed portion 42 and the work hole 14 are positioned by the convex portion 42b formed on the fixed portion 42 and the first connecting portion 43a coming into contact with the work hole 14. Regardless of the configuration, it is possible to position the fixing portion 42 and the work hole 14. For example, when the width W3 of the first connecting portion 43a is formed to be substantially equal to the diameter D1 of the work hole 14, the connecting portion serves as a positioning portion that restricts the movement of the drain valve 40 in the longitudinal direction of the sash 1b. The movement of the connecting portion 43a in the longitudinal direction of the sash 1b is restricted. Therefore, the fixed part 42 and the work hole 14 are positioned.

-In the said embodiment, the valve part 41 of the drain valve 40 is formed thinner than the connection part 43, but if it is the thickness which can be rock | fluctuated according to an atmospheric pressure difference, it is the thickness equivalent to the connection part 43. There may be.
In the above embodiment, the valve portion 41 is urged by the connecting portion 43, but if the valve portion 41 is disposed near the opening of the drain hole 13 and can swing according to the atmospheric pressure difference, the connecting portion 43. It may not be energized by.

  In the above embodiment, the working hole 14 is closed only by the glass run 4, but is not limited to this mode, and may be closed by the glass run 4 after being closed by another member.

  -In the said embodiment, the width W2 of the fixing | fixed part 42 is formed according to the width W of the groove | channel 11a, and positioning of the valve part 41 is made | formed by the movement of the fixing | fixed part 42 being controlled. It is not limited. For example, if a groove having a width slightly larger than the diameter of the drain hole is formed on the surface of the sash 1b on the side opposite to the window glass along the longitudinal direction of the sash, movement of the valve portion in the width direction is restricted by the groove. And positioned.

  In the above embodiment, the work hole 14 is formed in a circular shape having a diameter D1 larger than the diameter D of the drain hole 13, but the diameter D1 of the work hole 14 may be equal to the diameter D of the drain hole 13. . Further, the work hole 14 and the drain hole 13 may not be formed in a circular shape.

  -In above-mentioned embodiment, although the connection part 43 is arrange | positioned between the valve part 41 and the fixing | fixed part 42 in the longitudinal direction of the sash 1b, it is not limited to such an aspect. For example, when the fixing portion is extended to the drainage hole side in the longitudinal direction of the sash, the fixing portion and the connecting portion overlap in the thickness direction of the drainage valve, the bottom portion is sandwiched between the connecting portion and the fixing portion, and the drainage valve is fixed to the sash. The Therefore, it is possible to reduce the possibility that the position of the drain valve (valve part) is shifted after the drain valve is arranged and before the work hole is blocked by the glass run and the drain valve is fixed.
