[0003]

However, in the above-described conventional center partition structure of the sliding window for a vehicle, in the initial state, the lip is pressed against the glass based on its elasticity to maintain the sealing property. However, if the lip deteriorates with time and loses its elasticity, there is a problem that the sealing performance may not be maintained. The present invention
Focusing on the above-mentioned conventional problems, it does not greatly change the basic shape and seals even if the lip deteriorates with time and loses elasticity without deteriorating the openability of the glass. The purpose is to be able to keep.

[0004]

Means for Solving the Problems According to the present invention, the sash is erected in a state sandwiched between an outer glass and an inner glass which are pulled and supported in a groove provided in the sash, and has elasticity. A core material having a thin plate shape and having a thickness direction directed toward the inside and outside of the vehicle, and a soft outer front projecting from a vehicle outer surface of the core material obliquely to the front and rear of the vehicle over substantially the entire length of the core material. A lip and an outer rear lip, and a soft inner front lip and an inner rear lip protruding from the inner side surface of the core material in the oblique front and rear inward direction over substantially the entire length of the core material. A center partition structure of a sliding window for vehicles that elastically deforms so as to reduce the gap with the core material and is pressed against both glasses to seal the gap between the two glasses, and is located diagonally in each lip Outer front lip and inner rear lip, Alternatively, between the outer rear lip and the inner front lip, and the core material, a rib is provided over at least one of the lip and the core material in a direction to reduce a distance therebetween, and a rib protrusion amount However, when the center partition and both glasses are assembled, the amount is set so as to fill the gap between each lip and the core material. In addition, although the position of each lip is specified with the width direction of the core material as the front-back direction in the expression, when the sliding window is provided on the front-rear surface of the vehicle, the front-rear direction in the claims is the left-right direction.

[0005]

When the center partition and the inner and outer glass are assembled to the sash, the center partition is sandwiched between the inner and outer glass and each lip is pressed by the glass, whereby the center partition is elastically deformed in a direction approaching the core material. At this time, in the outer front lip and the inner rear lip in which the rib is provided between the core material and the outer rear lip and the inner front lip, the gap between the core material and the outer front lip is filled with the rib. Abuts against each glass not only with the restoring force based on the elasticity of the lip itself, but also with the bottom supported by the core material. Therefore, even when the elasticity of the lip is lost, the minimum contact is compensated and the sealing property is maintained.

Further, since the ribs are provided between the diagonally arranged lips and the core material, if there is a dimensional error and the contact of each lip with each glass is increased, the ribs are provided. The material is elastically deformed so as to be twisted by receiving the reaction force at one of the inside and outside of the front part and the other inside and outside of the rear part. Thus, it is possible to prevent the pressure force of each lip from increasing and the sliding resistance of each glass from becoming excessive. That is, assuming that the rib is provided not on the diagonally located lip and the core material but only on one of the front and rear, that is, the outer front and inner front lip, or the outer rear and inner rear lip,
The core material receives the reaction force inside and outside the front side or inside and outside the rear side, and the reaction force received from one glass pushes the other glass as it is, the contact of each lip becomes strong and the sliding resistance Is excessive, but the present invention can prevent this.

Further, when one or both of the two glasses are slid, the glass is deformed by an external force such as wind pressure or the shape thereof is not constant, so that the contact between the glass and each lip increases. Also in this case, the core material is deformed so as to be twisted by the reaction force in the same manner as described above, thereby preventing the sliding resistance from becoming excessive.

Embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 4 is a front view showing a sliding window W for a vehicle to which the first embodiment is applied. The sliding window W is provided on a side surface of a vehicle. A sash 1 having a rectangular frame shape fixed to the opening formed in the sash 1 and a groove 2a (see FIG. 5) formed in a glass run 2 provided on the inner periphery of the sash 1 are slidably supported by sliding. The outer glass 3 and the inner glass 4 are sandwiched between the two glasses 3 and 4 at the overlapping portion of the two glasses 3 and 4 at the center in the front-rear direction of the sash 1 (FR indicates the front in the figure). Center partition 5 provided in a closed state
And

FIG. 1 is a cross-sectional view of the center partition 5, in which a core member 5c is formed by a thin stainless steel plate 5a and a hard resin layer 5b such as vinyl chloride coated on the surface of the stainless steel plate 5a. ing. An outer front lip 5d and an outer rear lip 5e are provided diagonally outward from the center of the outer surface of the core member 5c. The lip 5f and the inner rear lip 5g are provided integrally. Each of the lips 5d to 5g is made of a soft material such as rubber or a soft resin such as soft vinyl chloride.

The dimension La between the leading ends of the outer lips 5d and 5e and the leading ends of the inner lips 5f and 5g in the vehicle width direction is a cross section taken along line S2-S2 in FIG. The dimension is set to be larger than the dimension Lb between 3 and 4.

Also, as shown in FIGS.
c, the outer rear lip 5e, the inner front lip 5f and the core material 5 extend over substantially the entire length in the vertical direction.
The ribs 5h and 5j are formed to project in a direction to narrow the interval between the ribs 5h and 5j. The projecting amounts of the ribs 5h and 5j are set to an amount sufficient to fill the gaps between the lips 5e and 5f and the core member 5c in the assembled state shown in FIG.
The ribs 5h and 5j are located at diagonal positions opposite to those illustrated.
That is, the lips 5d and 5g may be protruded to a position where the distance between the core 5c and the lip 5d is reduced.

FIG. 5 is a sectional view taken along line S5-S5 of FIG.
As shown in this figure, brushes 6a and 6b are provided by cutting the glass run 2 above and below the center of the sash 1 where the center partition 5 is provided in the vehicle longitudinal direction. A hook 5k is formed at the upper end of the center partition 5 by bending the upper end of the stainless steel plate 5a of the core 5c in an inverted L-shape.
The bracket 7 is fixed to a substantially concave locking portion 7a formed by cutting and raising a part of the bracket 7 fixed to the upper end of the bracket 7. On the other hand, the lower end of the center partition 5 is placed so as to be embedded in the brush 6b.

Next, the operation and effect of the first embodiment will be described. When the center partition 5 is attached to the sash 1 and the inner and outer glasses 3, 4 are attached to the sash 1,
Since the dimension Lb between the inner and outer lips is smaller than the dimension La between the glasses, as shown in FIG.
Is pressed against each glass 3, 4 while being elastically deformed by being pressed by each glass 3, 4, and each lip 5e, 5f is pressed by the ribs 5h, 5j to be in a bottomed state.

At this time, the actual dimension Lb between the glasses 3 and 4 is smaller than the design value, or each lip 5
If the actual dimension La between d and 5 g is larger than the design value, the hit of the lips 5 e and 5 f backed up by the ribs 5 h and 5 j against the glasses 3 and 4 will increase. However, in this case, the core material 5c is elastically deformed so as to be twisted as shown in FIG. 3 by the reaction force received through the ribs 5h and 5j, and the pressing force of the lips 5e and 5f backed up by the ribs 5h and 5j. (Sliding resistance) does not become unnecessarily large.
Slide 4 is performed smoothly. Also, even if the dimension Lb between the two glasses and the dimension Lb between the lips are within the set values, the sliding resistance when any one of the glasses 3 and 4 is slid is reduced by wind pressure or molding pressure. Even if the glass becomes unnecessarily large due to bending of the glass within the range of error, the core member 5c is elastically deformed as shown in FIG. 3 to reduce the resistance.

Next, each lip 5d to 5g is deteriorated with time.
Loses elasticity, the lips 5e and 5f with which the ribs 5h and 5j are in contact maintain the pressure contact state by the ribs 5h and 5j and maintain the sealing property. Thus, the inner and outer lips 5e and 5f Since the sealing property is maintained, the sealing property between the glasses 3 and 4 is maintained.

As described above, the first embodiment has a simple configuration in which the ribs 5h and 5j are provided on the core member 5d, that is, a configuration in which the number of parts does not change and the manufacturing cost does not largely differ from the conventional one. Even if the lips 5d to 5g deteriorate over time and lose their elasticity, the sealing properties can be maintained, and even if there is a dimensional error in the dimension Lb between the glasses and the dimension La between the lips, and even when there is no dimensional error, each glass 3 Even if the contact with the lips 5e and 5f increases due to the change in the shape of the glass plates 3, 4, the effect of preventing the sliding resistance of the glass plates 3, 4 from becoming excessive is obtained.

(Embodiment 2) Next, Embodiment 2 shown in FIG. 6 will be described. In describing the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted. In the second embodiment, each lip 5 is replaced with the ribs 5h and 5j provided on the core 5c.
This is an example in which ribs 5m and 5n are provided integrally with d and 5g. Also in the second embodiment, the same operation and effect as in the first embodiment can be obtained. Since the material forming each lip 5d, 5g is softer than the hard resin layer 5b of the core material 5c, the protrusion amount of each rib 5m, 5n is equal to each rib 5h, 5h of the first embodiment.
5j is larger than the protrusion amount. Instead of the second embodiment, ribs may be formed so as to face both the lips 5e and 5f and the core 5c, or both the lips 5d and 5g and the core 5c.

As described above, the case where the vehicle window is provided on the side surface of the vehicle has been described in the embodiment, but it is also possible to provide the vehicle window on the front surface or the rear surface of the vehicle.

[0019]

As described above, in the center partition structure of the sliding window for a vehicle according to the present invention, the lip between the diagonally located lips of each lip and the core material are provided.
Ribs are projected in the direction to narrow the gap between each lip and the core, and the amount of protrusion of this rib is set to an amount sufficient to fill the gap between each lip and the core during assembly. The lip backed up by the ribs can maintain the sealing performance even if each lip deteriorates with time and loses elasticity with a simple configuration that does not change the number of parts and the manufacturing cost is not much different from the conventional one. Effect is obtained, and
Even if there is a dimensional error in the dimension between the glass and the dimension between the lips, or even when there is no dimensional error, even if the contact with each lip increases when assembling or sliding the glass by changing the shape of each glass, By elastically deforming the material so as to be twisted, an effect is obtained that the sliding resistance of each glass can be prevented from becoming excessive.
