Description

[Detailed Description of the Invention] This invention relates to a window frame for an automobile, and more specifically, to an improvement of a window frame that is attached to an automobile body to form an opening/closing window in an automobile.

For example, as shown in FIG. 9, a conventional window frame of an automobile that can be opened and closed is arranged on the inner circumference of the window opening of the automobile body 21, and is made of a metal support frame 2.
2. The outer locking piece 23 is attached to the flange portion 2 around the window opening of the automobile body 21 using the frame-shaped clip 24.
5 and is fixed. Fitting portions (generally referred to as glass runs) 26, 26 made of an elastic member are attached within the support frame 22, so that slide glasses 27, 27 can be slid thereon. 28 is a seal piece (dam) that seals the gap between the inner peripheral surface of the window opening and the support frame 22. However, the clip 24 on the window frame 29 has a drawback that the clip 24 tends to come off from the window frame 29 locking piece 23 or the flange portion 25 at the corner portion of the window frame 29 due to long-term heat shrinkage.
The glass run 26 attached to the support frame 22 also has the disadvantage that it tends to come off from the support frame 22 at the corners due to long-term heat shrinkage.

Therefore, the present inventor has devised a window frame for automobiles that can eliminate the conventional drawbacks. In other words, the purpose of the present invention is to provide a glass slide with good sliding properties and good sealing properties when closed, as well as to have sufficient adhesion to the flange of the window opening of the automobile body, and to provide a glass run. Another object of the present invention is to provide a window frame for an automobile in which the sealing member has good adhesion and does not come off due to long-term heat shrinkage.
Another object of the present invention is to provide an automobile window frame that is easy to manufacture and easy to attach to a window opening in an automobile body.

Next, the present invention will be explained with reference to illustrated embodiments embodying the invention. 1 to 8, reference numeral 1 denotes an annular (in this example rectangular) window frame attached to a window opening of an automobile body 16, with a support frame 2 made of rigid metal and a support frame 2 made of soft vinyl chloride resin. It is formed by covering an elastic member 3. The support frame 2
is formed into a rectangular shape by bending a long frame material with a cross section such that the concave side is inside,
Both ends 2A, 2A of the bent frame material are connected to each other by caulking rivets 13 to 13 with a connecting plate 12 placed on the back surface. In addition, both ends 2A of the frame material,
2A may be connected by other connection means such as welding. The elastic member 3 attached to the support frame 2 is formed by a series of predetermined pieces such as the fitting parts 4 and 5 of the slide glasses 14A and 14B and the fitting parts 6 and 8 that cover the outer surface of the support frame 2. It is a long piece made of
It is annularly bonded along the circumference of the support frame 2 by vulcanization bonding or adhesive. In the elastic member 3, reference numerals 4 and 5 are fitting portions for slidably fitting the slide glasses 14A and 14B into the recessed portions of the support frame 2, and 4A, 4B and 5A and 5B are fitting portions at the upper ends of the fitting portions 4 and 5. This is a contact piece for contacting the slide glasses 14A, 14B. Reference numeral 6 denotes an attached part whose upper end is connected to the contact piece 4A, and is adhered to the outer surface of the support frame 2 on the outside of the vehicle. Reference numeral 7 denotes a sealing piece provided at the outer circumferential end of the adhered portion 6, and is adapted to seal the gap between the support frame 2 and the circumferential portion of the window opening. Reference numeral 8 denotes an attached part whose upper end is connected to the contact piece 5B and which is adhered to the outer and lower surfaces of the support frame 2 on the vehicle interior side. Reference numeral 9 denotes a seal piece connected to the outer peripheral end of the adhered portion 8. Reference numeral 10 denotes a clamping piece that is connected to the inner peripheral end of the adhered part 8 and clamps the flange part 19 between it and the adhered part 8, and the clamping piece 10 is elastically moved toward the adhered part 8 side. Always energized.

Therefore, the window frame 1 of this example is inserted into a predetermined window opening 18 of the automobile body 16, in this example, the opening/closing door 17, from the outside of the vehicle, and the clamping piece 10 of the window frame 1 is opened, and the cover on the vehicle interior side is inserted. The window frame 1 is press-fitted until the flange part 19 comes into contact with the fitting part 8, and then the clamping piece 10 is returned and the window frame 1 is fixed to the flange part 19 by the elastic biasing force of the clamping piece 10. The seal piece 9 at the end of the adhered part 8 is inserted between the periphery of the window opening 18 and the window frame 1, that is, the support frame 2, by press-fitting the window frame 1, and fills the gap S on the passenger compartment side of the window opening 18. Seal.
Further, the seal piece 7 at the end of the adhered part 6 on the other side of the window frame 1 is attached to the outside of the window opening 18 of the window frame 1.
The gap S between the circumferences of No. 8 is closed.

Note that since the window frame 1 of this example is fixed to the flange portion 19 by the clamping pieces 10, a locking piece 23 is provided on one side of the window frame 1, and the locking piece 23 and the flange portion 25 are connected with the clip 24. Compared to the conventional case where the window frame 1 is fixed (see FIG. 9), the window frame 1 of this example is advantageous in that the width of the frame can be made narrower during installation.

As explained above, the present invention is an annular window frame that is attached to an automobile window opening having a flange portion on the inner periphery to form an opening/closing window, and which has a substantially same shape as the inner periphery of the window opening and which slides. A support frame having a recess for forming a glass fitting part has a fitting part that fits slidably with the slide glass in the support frame recess, a contact piece that contacts the surface of the slide glass, a support frame, and a window opening. The window frame is made up of a series of elastic members, each consisting of a sealing piece that seals between the circumferences of the support frame recess and a clamping piece that clamps the flange on the outside of the support frame recess. The above-mentioned intended objectives will definitely be achieved. In other words, since the window frame of the present invention is fixed by being fixed to the flange of the car body window opening using the fastening pieces of the attached elastic member, the window frame is well fixed to the car body. The gap between the window opening and the window opening is sealed by the sealing piece, so the window frame does not wobble.
In addition, since the elastic member in the window frame of the present invention has a series of fitting parts and sealing pieces attached to the support member, it has good adhesion to the support frame and the elastic member has good adhesiveness to the support frame and the elastic member has a sealing piece formed in a series. Shrinkage is prevented even when changes occur, the attached window frame has good adhesion over a long period of time, and is easy to manufacture. Furthermore, slide glass is fitted into the fitting part of the window frame attached to the car body to form a window that can be opened and closed freely, but of course the airtightness of the window when closed with slide glass is not good. be.
