Description
Background of the Invention
1. Field of the Invention
The present invention relates to a mounting construction of window glass for vehicle, particularly, of a fixed type.
2. Description of the Prior Art
In the windshield glass for the vehicle, there are two types, one of which is an opening and closing type and the other is a fixed type. The windshield glass of the opening and closing type and that of the fixed type are different from each other in mounting construction. In general, the latter is subjected to fixed fitting on a body panel of the vehicle through a sealing gasket.
FIG. 1 is a perspective view showing a conventional mounting construction of window glass 10 in a rear quarter portion of the vehicle body. FIG. 2 are sectional views taken along a line II--II of FIG. 1 in which three types of fixed mountings are shown according to differences in mounting construction. In FIGS. 2(A) and (B), the window glass 10 is fixed to the quarter portion through a weather strip 12 functioning as gasket and the weather strip 12 is provided at its outer face with a moulding 16. In FIG. 2(C), the window glass 10 is fixed to the quarter portion through a resin clip 14 and the resin clip 14 is secured thereto with the moulding 16.
In the types of FIGS. 2(A) and (B), however, the weather strip 12 can not be reduced in its thickness since its operation as gasket must be maintained and, therefore, the moulding 16 is disposed at a position projected largely from an outer face of the window sealed glass 10 outwardly by an amount of H, which results in increase in air resistance when the vehicle is operating particularly at high speeds. It also detracts from the appearance of the vehicle. In the type of FIG. 2(C), the resin clip 14 supporting the moulding 16 must be given a predetermined rigidity, so that it can not be reduced to any significant extent in thickness.
Accordingly, for example, Japanese Utility Model Laid-Open Publications Nos. 57-14113 and 58-135310 appear to be intended to solve these problems.
Summary of the Invention
In view of the above facts, the present invention has as its object the provision of a mounting construction of window glass for a vehicle in which a projected amount of a moulding from the window sealed glass can be reduced, so that air resistance of the vehicle is reduced when the vehicle is being operated, while not impairing the appearance of the vehicle.
In a mounting construction of window glass of a fixed type for a vehicle according to the present invention, a retainer supporting a window glass is fixed to a body panel of the vehicle, a sealer is disposed between the window glass and a body panel of the vehicle, and a moulding is disposed to cover an outer face of a peripheral portion of the window glass, whereby the moulding projecting from the window glass is reduced.
The accompanying drawings, which are incorporated and constitute part of the specification, illustrate the preferred embodiments of the invention and, together with the description, serve to explain the principles of the invention.

Preferred Embodiments of the Invention
Reference will now be made in detail to presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.
In FIG. 3, shown is a window glass or windshield 20 fixed to a quarter portion of a vehicle body, according to the mounting construction of the present invention. Also, FIG. 4 is a sectional view of the mounting construction.
The window glass 20 is provided at its peripheral portion with a moulding 24 which is made of stainless steel and has a base portion 24A and an upper panel portion 24B, as shown in FIG. 4. That is to say, the moulding 24 has a sectional configuration of a substantial L shape, as shown in FIG. 5. The moulding 24 is fixed to its end periphery with resin material 24C for decorating the periphery of the window glass 20.
The moulding 24 is fixed along the base portion 24A to a retention plate, such as retainer 26, by a spot welding or the like, as shown in FIG. 4.
The retainer or retention member 26 has a base plate portion 26A fixed thereto with a bolt 28 as fixing means. The retainer 26 also includes a side plate portion 26B extended substantially at a right angle from the base plate portion 26B. The side plate portion 26B is formed at its both side portions with two bent portions 26C (i.e., a retention plate portion having a pair of support arms), bent in such a directions that the bent portions 26C, the side plate portion 26B and the base plate portion 26A constitute a channel, as shown in FIGS. 4 and 6. Accordingly, the bent portions 26C and the upper panel portion 24B are positioned substantially in parallel with each other and the window sealed glass 20 is received between the moulding 24 and a cushion abutting on the bent portions 26C. The side plate portion 26B has at its intermediate portion, i.e., between the bent portions 26C, a projection portion 26D extended outwardly, as shown in FIGS. 4 and 6. The projection portion 26D abuts on cushion means 22 extending along an inner surface and an end face of the window sealed glass 20.
The bolt 28 penetrates the retainer 26 and body panels 30 and 31, and it is fixed to the body panel 31 from inside thereof by a nut 32. In this connection, disposed between the base plate portion 26A of the retainer 26 and the body panel 30 is a sealer 25, or sealing material, for preventing water from leaking into the vehicle compartment. Disposed between the body panel 30 and the window glass 20 is a sealer 34 for sealing a space therebetween, and a conventional sealer, i.e., conventional sealing material for vehicle, can sufficiently be applied to the present invention.
In this embodiment the cushion means 22 is made of an elastic body such as a rubber or polyvinyl chloride resin. In accordance with this embodiment, the moulding 24 does not project significantly from the outer face of the window glass 20, so that the projected amount of the moulding 24 is substantially reduced to be largely the thickness of the upper panel portion 24B of the moulding 24. In addition, when an external force acts upon an outside face of the window glass 20, the force can be sustained by the bent portions 26C of the retainer 26, and when an external force acts upon an inside face thereof, it can also be sustained by the moulding 24. Accordingly, a sufficient strength can be obtained without using a weather strip or a resin clip in the embodiment.
According to a second embodiment of the present invention, a window glass 20 is fixed to its peripheral portion with a retention clip or retainer 36 through a bonding agent or the like, as shown in FIG. 7. The retainer 36 has a base plate portion 38 supporting a bolt 40 as fixing or retention means and a side plate portion 42 bent substantially at a right angle from the base plate portion 38. As shown in FIG. 8, side plate portion 42 supports two bent portions 44 disposed at opposite sides of the side plate portion 42 and bent in such a direction that the window glass 20 is grasped between the base plate portion 38 and the bent portions 44. Each of the bent portions 44 is further formed at its forward end portion with a step portion 46. In addition, the side plate portion 42 is formed at its intermediate portion, i.e., between the bent portions 44, with a projection portion 48 projected in a direction away from the bent portions 44. The window sealed glass 20 is received between the bent portions 44 and the base plate portion 38, and a moulding 50 described in detail later on is engaged with the step portions 46 and the projection portion 48, as shown in FIG. 7.
The bolt 40 is welded on to the retainer 36 and the belt 40 includes, along its intermediate portion, a flange 52 as a sealing member. The flange 52 is caused to abut on the inside face of the body panel 30 to keep constant a space between the window glass 20 and the body panel 30. Therefore, the flange 52 functions as a spacer. In addition, the bolt 40 penetrates the body panels 30 and 31 to be fixed to the body panels 30 and 31 by a nut 54 from an inside of the vehicle body.
The retainer 36 is preferably made of substantially flexible metal material, such as stainless steel or spring material.
The moulding 50 including an upper panel portion 50A and an inwardly projecting side panel portion 50B has a sectional configuration of an approximate L shape and the upper panel portion 50A and the side panel portion 50B are respectively formed at their edge portions of a sectional direction thereof with hook portions 50C and 50D bent towards insides of the L shape as shown in FIG. 7. Therefore, the moulding 50 is engagable with the retainer 36 through the hook portions 50C and 50D. Also, the moulding 50 is fixed at its forward end portion with resin material 58 which abuts on an outer face of the window sealed glass 20.
In addition, disposed between the window glass 20 and the body panel 30 is a sealer 56 as in the first embodiment, whereby a sealing therebetween is maintained. In this embodiment, also, the conventional sealer can be used as well in the first embodiment.
According to the embodiment of the present invention, the moulding 50 is not disposed to project significantly from the outer face of the window glass 20. In addition, when an external force acts upon an outside face of the window glass 20, it can be sustained by the retainer 38 and the flange 52, and when an external force acts upon an inside face thereof, it can be sustained by the bent portions 44 of the retainer 36. Thus, a sufficient strength can be obtained even without using the weather strip or the resin clip of the first embodiment.
In the above two embodiments, typically ten sets of the retainers and the bolts are applied to the window glass 20, as shown in FIG. 3; however, the number of the set may be depending on the size or mounting condition of the window glass 20.
The configurations of the retainer and the moulding are not limited only to those of the first and second embodiments but they can be changed or modified appropriately, if necessary.
In the embodiment the retainer is connected to the body panel through the bolt but the other connecting means can also be applied to the present invention.
It will be apparent to those skilled in the art that modifications and variations can be made to the window glass mounting construction of the present invention. The invention in its broader aspects is, therefore, not limited to the specific details, representative apparatus, and illustative examples shown and described. Thus, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
