Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a window structure for a vehicle such as a bus, and more particularly to a sliding window structure in which the window frame can be slid to open and close.

[Conventional technology]

Generally, buses have a large number of windows in their passenger compartments. Some of these windows are fixed window glass types so that they cannot be opened or closed, but as shown in FIG. An inner window frame with a window glass 6 that can be moved in the longitudinal direction of the vehicle along guide rails 5, 5' with upper and lower surfaces on the inner circumference of the window outer frame 4, into which an aluminum outer window frame 4 is fitted. 7, so that the windows can be opened and closed.

In addition, numerals 8 and 8' in Fig. 2 are auxiliary spacers for adjusting the distance, 9 and 9' are screws for attaching the window frame 4 to the window opening 2, and 10 is a sponge window opening. Corner sealing material, 11,
Reference numeral 11' indicates a drainage rubber, and reference numeral 12 indicates a launch channel.

[Problem that the invention attempts to solve]

However, with such conventional sliding window structures for vehicles, depending on how they are attached to the vehicle body, the cross section of the window outer frame may be deformed and the frontage may change, resulting in vertical play in the window inner frame. There are problems in that sticking occurs and the force required to open and close the window increases.

The present invention aims to solve these problems, and allows the window to be opened and closed smoothly without causing the inner frame of the window to wobble in the vertical direction.
To provide a sliding window structure for a vehicle that can reliably prevent rainwater from entering.

[Means for solving problems]

For this reason, the sliding window structure for vehicles of the present invention is
An outer window frame fitted to a vehicle window opening, an inner window frame with a window glass fitted to the outer frame of the window, a lower guide rail provided on the lower inner circumferential surface of the window outer frame, and a lower guide. a fitting portion formed on the inner frame of the window to allow the inner frame of the window to slide along the rail, and fitting with the lower guide rail so as to cover the upper part and both sides of the lower guide rail; A launch channel made of a soft elastic material is provided between the mating part and the lower guide rail and attached to the mating part,
The lower guide rail is configured as a headed rail having an enlarged portion at its tip end that bulges out at least toward the passenger compartment, and the launch channel has an upper portion located above the lower guide rail and an outer side of this upper portion. A first side portion that is connected and interposed between a vehicle exterior side surface of the lower guide rail and a vehicle exterior side surface of the fitting portion opposing this side surface, and a first side portion that is connected to the vehicle interior side of the upper portion. and a second side portion interposed between a side surface of the lower guide rail on the inside of the vehicle interior and a side surface of the fitting portion on the inside of the vehicle interior opposite to this side surface, and The part has a wall thickness thinner than the distance between the outer side surface of the lower guide rail and the outer side surface of the fitting part, and extends over a predetermined vertical range between the upper and lower ends of the lower guide rail. A seal portion is formed that abuts the outer side surface of the vehicle, and the second side portion has a wall thickness thinner than the distance between the inner side surface of the lower guide rail and the inner side surface of the fitting portion. A bent edge is formed to engage the enlarged portion of the lower guide rail from below in order to suppress the rise of the window inner frame.

[Effect]

In the sliding window structure for a vehicle of the present invention described above, the inner window frame is fitted into the outer window frame so as to slide along the lower guide rail with the inner circumferential lower surface of the outer window frame, but at this time, the inner window frame and the lower guide rail A bent edge is formed on the launch channel located between and attached to the window inner frame, and this bent edge engages with the enlarged part of the lower guide rail from below, thereby preventing the rise of the window inner frame. This sufficiently prevents the window inner frame from shaking in the vertical direction, allowing smooth window opening and closing operations. In addition, the seal portion formed over the upper predetermined range of the launch channel is
In addition to reliably preventing rainwater from entering, since this seal is provided on the outside of the vehicle, it also prevents rainwater from being directed toward the lower guide rail. This works to extremely reduce the probability that rainwater will be introduced into the interior of the vehicle.

〔Example〕

Hereinafter, a sliding window structure for a vehicle as an embodiment of the present invention will be explained with reference to the drawings. FIG. 1 is a sectional view showing the main parts thereof.
The same reference numerals as in the figure indicate substantially similar parts.

This structure is applied, for example, to a bus, and a large number of window openings are formed in the side wall of the passenger compartment of this bus. That is, as shown in Figure 1,
A plurality of window openings 2' are formed in the vehicle body 1, and an aluminum window frame 14 is fitted into the inner peripheral surface of each window opening 2' via a polypropylene spacer 13. installed.

Incidentally, the spacer 13 is attached to the inner circumferential surface of the window opening 2' via a butyl tape 18 as an elastic tape, and the abutting surface 13a of the spacer 13 to the window frame 14 is approximately on the window frame 14. It extends across its entire width. Note that the spacer 13 and the window outer frame 14 are attached with adhesive.

Further, a screw 19 is provided for tightening and fixing the window frame 14 to the peripheral edge of the window opening 2' by compressing the butyl tape 18. Here, the degree of tightening by the screw 19 is such that, for example, the butyl tape 18 having a thickness of about 4 mm is compressed to about 2 mm.

A spacer 13' is interposed between the lower part of the window frame 14 and the window opening 2', and the screw 1 is inserted at the spacer insertion part.
It is stopped at 9'. And this spacer 1
The structure of 3' and spacer insertion part is the same as spacer 1 above.
3 and the structure of the inserted portion of the spacer 13.

Furthermore, upper and lower guide rails 15 and 15' are formed on the upper and lower surfaces of the inner periphery of the window outer frame 14, respectively, two on the inner and outer sides. 1
7 is fitted through the launch channel 22. This allows the window inner frame 17 to slide in the longitudinal direction of the vehicle along the guide rails 15, 15' as a sliding window.

Here, the lower guide seal 15' is attached to the window inner frame 17.
A fitting part 17a that fits into the lower guide rail 15' is formed so as to cover the upper part and both sides of the lower guide rail 15' so as to slide on the window inner frame 17 along the inner window frame 17. and lower guide rail 1
A launch channel 22 made of a soft elastic material and disposed between the fitting portion 17 and the fitting portion 17 is attached to the fitting portion 17.

Furthermore, a window glass 16 is fixedly fitted into the window inner frame 17 via a rubber material 23.

By the way, the lower guide rail 15' is configured as a headed rail having an enlarged portion 15'a at the tip, whereas the upper guide rail 15 is configured as a headless rail having a straight cross section without an enlarged portion at the tip. It is configured.

The launch channel 22 is attached to the window inner frame 17 side and has a substantially U-shaped cross section, and is slidably engaged with the guide rails 15, 15' at this U-shaped portion.
This launch channel 22 has a waterproof fin portion 22a that is slidably in close contact with the outer surface (flat surface) of the upper guide rail 15, so that the inner window frame 17
It is designed to be able to exhibit sufficient waterproof function while allowing for sliding movement.

Although not shown, there are also an upper guide rail 15 and a lower guide rail 15' on the front and rear surfaces of the inner periphery of the window frame 14.
A guide rail is formed that extends vertically to connect the window inner frame 17 in one direction (in the case of the other window inner frame 17, the window inner frame 17 is shifted in the other direction).
A launch channel portion with a front edge or a rear edge of the window inner frame 17 is adapted to engage with this guide rail. That is, the guide rail is connected to the window outer frame 14.
A run is provided along the entire inner circumference of the window frame 17 (including when it is partially cut off in the middle), and also extends all the way around the outer circumference of the window inner frame 17 (including when a launch channel is spliced in the middle). This means that a channel has been applied.

The launch channel portions (front and rear lower launch channel portions) that can come into contact with guide rails other than the upper guide rail 15 are also provided with a fin portion similar to the waterproof fin portion 22a (that is, this fin portion is attached to the outside of the guide rail). ) that is slidably attached to the side surface.

Thereby, the function of preventing rainwater from entering from outside the vehicle can be ensured over the entire circumference of the window inner frame 17.

Further, the launch channel portion that engages with the lower guide rail 15' disposed on the lower side of the window inner frame 17 includes an upper portion located above the lower guide rail 15' and an outer side of this upper portion (the first a first side portion connected to the left side in the figure and interposed between the vehicle outer side surface of the lower guide rail 15' and the vehicle outer side surface of the fitting portion 17a opposing this side surface; and the above-mentioned upper portion. The second rail is connected to the interior side of the vehicle (on the right side in FIG. 1) and is interposed between the interior side surface of the lower guide rail 15' and the vehicle interior side surface of the fitting portion 17a facing this side surface. the first side portion is the outer side surface of the lower guide rail 15' and the fitting portion 17a.
A seal portion is formed to have a thickness thinner than the distance between the lower guide rail 15' and the outer side surface of the vehicle, and is formed at an intermediate portion between the upper end and the lower end of the lower guide rail 15' over a predetermined vertical range and abuts against the outer side surface of the lower guide rail 15'. The second side portion is formed to have a thickness thinner than the distance between the inner side surface of the lower guide rail 15' and the inner side surface of the fitting portion 17a, and is designed to suppress the rise of the window inner frame 17. A bent edge 22b is formed to engage the enlarged portion 15'a of the rail 15' from below.

That is, since the outer surface of the lower guide rail 15' is formed flat, the lower guide rail 15'
The enlarged portion 15'a is formed to bulge inward, so that the lower guide rail 1 is formed on the inside of the vehicle.
5' and the bent edge 22b of the launch channel 22 will be present.

This prevents the window inner frame 17 from shaking vertically, and since the upper guide rail 15 is configured as a headless rail with a straight cross section, the movement of the window inner frame 17 is not hindered. As a result, it is also possible to prevent the window inner frame 17 from swinging back and forth.

In addition, the code 18' in FIG. 1 is butyl tape,
Reference numeral 20 indicates an edge trim for covering the edge of the window opening 2' on the side of the passenger compartment, and reference numerals 21 and 21' indicate drainage rubber.

With the above configuration, when installing the window frame 14, the butyl tape 1 is applied to the inner peripheral surface of the window opening 2'.
Fit the window outer frame 14 to the inner peripheral surface of the window opening 2' via the butyl tape 18 and the spacer 13 so that the outer frame 14 is in contact with the inner peripheral surface of the window opening 2' using the screw 19. Tighten and secure. At this time, since the contact surface 13a of the spacer 13 to the window frame 14 extends over almost the entire width of the window frame 14, the window frame 14 tends to deform to widen the frontage as the screws are tightened. This can be sufficiently prevented. Also, when tightening the screws, butyl tape 18
is compressed and a reaction force is generated, so even if the tightening force of the screw 19 is adjusted to adjust the frontage, for example, the screw 19 will not loosen, and the window frame 14 will not wobble.

The lower part of the window frame 14 is similarly attached to the window opening 2' with a screw 19' via a spacer 13' and a butyl tape 18'.

Furthermore, the window inner frame 17 connects the window outer frame 14 to the window opening 2'.
It is attached to the window outer frame 14 before or after the window frame 17 is attached, but when the window outer frame 14 is attached, there is no deformation to widen the frontage as in the conventional case, so the opening/closing operation force of the window inner frame 17 is large. It never becomes. In other words, smooth opening and closing of the window inner frame 17 can be expected.

In addition, since the fins 22a of the launch channel 22 are slidably in close contact with the outer surfaces of the guide rails 15, 15', sufficient waterproof function can be achieved without having to attach a canopy to the window frame as in the conventional case. Demonstrated.

Further, the enlarged portion 1 is inserted into the launch channel 22 from below the enlarged portion 15'a of the lower guide rail 15'.
Since the bent edge 22b that engages with the upper guide 5'a is formed, it is possible to suppress the rise of the window inner frame 17, thereby preventing the window inner frame 17 from shaking in the vertical direction. Since the rail 15 is configured as a headless rail having a straight cross section, it does not hinder the movement of the window inner frame 17, and as a result, it is possible to prevent the window inner frame 17 from swinging back and forth. In addition, a seal part is formed over a predetermined upper limit range on the launch channel part that engages with the lower guide rail 15' disposed on the lower side of the window inner frame 17, thereby reliably preventing rainwater from entering. can. Furthermore, since the seal portion is provided on the outside of the vehicle, rainwater is prevented from being directed toward the lower guide rail 15', so the probability that rainwater will be led to the inside of the vehicle via the lower guide rail 15' is extremely low. can do.

It goes without saying that this device can be similarly applied to vehicles other than buses.

[Effect of idea]

As detailed above, according to the vehicle sliding window structure of the present invention, the window outer frame fitted into the vehicle window opening, the window inner frame with window glass fitted to the window outer frame, and the above-mentioned A lower guide rail provided on the lower surface of the inner periphery of the outer window frame, and a lower guide rail formed on the inner window frame to allow the inner window frame to slide along the lower guide rail, and a lower guide rail provided above and on both sides of the lower guide rail. a fitting part that fits with the lower guide rail so as to cover it;
A launch channel made of a soft elastic material is disposed between the fitting part and the lower guide rail and is attached to the fitting part, and the lower guide rail has a tip facing at least toward the passenger compartment. The launch channel is configured as a headed rail having a swollen enlarged portion, and the launch channel is connected to an upper portion located above the lower guide rail and to the outside of the vehicle of this upper portion, and is connected to the outside side of the lower guide rail and this side. a first side portion interposed between the outer side surface of the fitting portion facing the outer side of the vehicle; a first side portion that is connected to the inner side of the vehicle interior of the upper portion and the inner side surface of the lower guide rail and this side surface; and a second side portion interposed between a side surface of the fitting portion on the inside side of the vehicle, which faces the side surface of the fitting portion, and the first side portion has a second side portion interposed between the side surface of the fitting portion on the outside of the vehicle and the side surface of the fitting portion. A seal portion is formed in the intermediate portion between the upper end and the lower end of the lower guide rail and has a wall thickness smaller than the distance from the outer side surface of the lower guide rail, and is in contact with the outer side surface of the lower guide rail over a predetermined vertical range. The side portion has a wall thickness that is thinner than the distance between the interior side surface of the lower guide rail and the vehicle interior side surface of the fitting portion, and the lower guide rail is enlarged in order to suppress the rise of the window inner frame. The lower guide rail has a simple structure in which a bent edge that engages from below is formed, and the enlarged part of the lower guide rail is formed so as to bulge inward, and the lower guide rail and launch channel are connected to the inside of the passenger compartment. Since there is an engaging portion with the bent edge, it is possible to prevent the upper limit of the window inner frame from wobbling. In addition, a launch channel made of soft elastic material is interposed between the lower guide rail and the window inner frame. (based on the points formed thinly)
Therefore, the binding force on the lower guide rail is not particularly strong, and the window inner frame can be moved slightly, which has the effect of absorbing play (installation error) between the window inner frame and the lower guide rail. In this case, since the seal portion is formed in the launch channel over a predetermined upper limit range, intrusion of rainwater can be reliably prevented. Furthermore, since the seal part is provided on the outside of the vehicle, rainwater is prevented from being directed toward the lower guide rail, and the probability that rainwater will be led to the inside of the vehicle via the rail can be extremely reduced. It has the following functions and effects.
