[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a transparent plate-like body with a resin frame, and more specifically, a transparent with a resin frame that allows a resin frame and a reinforcing member to be easily attached to a peripheral portion while reducing weight. It relates to a plate-like body.
[0002]
[Prior art]
For example, some vehicles such as automobiles have specifications with a sunroof. FIG. 3 is a schematic perspective view of a sunroof vehicle, FIG. 4 is a bottom view of a transparent plate-like body such as a sunroof, and FIG. 5 is a view taken along line VV in FIG. In the sunroof, a transparent plate-like body 4 is attached to an opening 3 formed in the ceiling portion 2 of the vehicle 1 so as to be opened and closed.
[0003]
The transparent plate-like body 4 is generally made of glass, and as shown in FIGS. 4 and 5, a resin frame body 5 for sealing is attached to the peripheral portion. Further, a metal frame-shaped reinforcing member 6 for installing a jig for attaching to the opening 3 of the ceiling portion 2 is attached to the peripheral portion of the inner surface. And attachment of the resin frame 5 and the reinforcement member 6 with respect to the peripheral part of the transparent plate-shaped body 4 is conventionally performed as follows.
[0004]
FIG. 6 is a partially enlarged side cross-sectional view showing the manufacturing process of the transparent plate-like body. First, the metal reinforcing member 6 is attached to a predetermined position of the lower mold 7, and the hollow member is formed such that the cut portion 10 of the resin hollow member 9 is fitted to the bent portion 8 formed at the tip of the reinforcing member 6. 9 is attached to a predetermined position of the lower mold 7. Further, the transparent plate-like body 4 made of glass is attached to a predetermined position of the lower mold 7, and finally these are sandwiched by the upper mold 11.
[0005]
Then, the hollow member 9 and the resin are integrated by injecting resin into the cavity space 12 formed between the upper mold 11, the transparent plate-like body 4, the hollow member 9, the reinforcing member 6, and the lower mold 7. Thus, the resin frame body 5 is formed, and the transparent plate-like body 4, the resin frame body 5, and the reinforcing member 6 are integrally fixed together by the injected resin.
[0006]
[Problems to be solved by the invention]
However, the above conventional transparent plate with a resin frame has the following problems.
That is, since the transparent plate-like body 4 is conventionally made of glass, there is a problem that the weight increases, and when applied as a sunroof for a vehicle, the fuel consumption is reduced along with the reduction in weight and weight of the vehicle. I cannot plan.
[0007]
Moreover, since the glass-made transparent plate-like body 4 is manufactured as a plate-like body having a uniform thickness due to the characteristics of glass, the transparent plate-like body is used to attach the resin frame body 5 and the reinforcing member 6 to the peripheral portion. 4, the hollow member 9, and the reinforcing member 6 must be placed between the upper mold 1 and the lower mold 7, and the resin must be injected into the cavity space 12.
[0008]
Further, since the resin frame 5 and the reinforcing member 6 are integrally fixed to the peripheral edge portion of the transparent plate-like body 4 by injecting the resin into the cavity space 12, the resin is made of the transparent plate-like body. 4 swelled from the outer surface of FIG. 4, and a relatively large step was formed between the resin frame 5 and the transparent plate-like body 4, and the appearance was not excellent.
[0009]
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide a transparent plate-like body with a resin frame in which a resin frame and a reinforcing member can be easily attached to the peripheral portion while reducing the weight. It is.
[0010]
[Means for Solving the Problems]
The present invention relates to a resin frame in which a film having a hard coat layer is laminated on at least an outer surface of a resin-made transparent plate-like body, a frame-shaped reinforcing member is provided on the inner surface, and a resin frame is provided on a peripheral portion. A transparent plate-like body, wherein a concave portion is formed on the outer peripheral edge of the transparent plate-like body, and a convex portion formed in the resin frame is fitted and fixed in the concave portion, and the transparent plate-like body The film non-laminated portion formed between the concave portion on the outer surface and the edge portion of the film is covered with the fin portion formed on the resin frame, and the convex portion is formed on the inner peripheral side peripheral portion of the transparent plate-shaped body, The concave portion formed in the reinforcing member is abutted and fixed to the convex portion, and the transparent plate-like body with a resin frame is provided.
In this case, a long hole extending in the direction of thermal expansion and contraction of the transparent plate-like body may be formed in the reinforcing member, and the reinforcing member may be fixed by a headed pin fitted into the transparent plate-like body through the long hole.
[0011]
According to the above means, the following operation can be obtained.
First, since the weight of the transparent plate-like body can be reduced by changing the material to resin, it is possible to reduce the weight of the vehicle and the like and to reduce the fuel consumption associated with the weight reduction.
In addition, since the transparent resin has good moldability, it is not necessary to form a plate-like body having a uniform thickness like glass, and processing of various shapes can be performed on the peripheral portion.
[0012]
Therefore, a concave portion is formed on the outer peripheral side of the peripheral portion of the resin transparent plate-like body.
And while making a resin frame contact | abut to a transparent plate-shaped body, the convex part formed in the resin frame was fitted to the said recessed part of a transparent plate-shaped body, and also the periphery of a transparent plate-shaped body as needed By adhering both with a double-sided tape provided between the part and the resin frame, it is possible to easily attach the resin frame to the periphery of the transparent plate-like body without using resin injection or other means It becomes. As in the prior art, it is also possible to attach the resin frame using means such as resin injection.
Moreover, since the strength of the resin frame attached to the transparent plate-like body is obtained by fitting the convex portion and the concave portion, the step between the transparent plate-like body and the resin frame body is made small and substantially flush. Thus, the appearance can be improved.
[0013]
And a transparent plate-shaped body can be made hard to be damaged by laminating | stacking the film which has a hard-coat layer on the outer surface of a resin-made transparent plate-shaped body. On the other hand, when the edge portion of the film hits the concave portion of the transparent plate-like body, the resin frame may not be attached properly, and a dimensional error may occur in the cutting of the film. Therefore, it is required to cut the film slightly smaller. As a result, a film non-laminated portion is formed between the recess on the outer surface of the transparent plate-like body and the edge of the film.
Therefore, by forming a fin part on the upper part of the resin frame to cover the film non-laminated part, it is possible to protect the film non-laminated part and prevent peeling of the film non-laminated part. Become.
[0014]
By the way, when the transparent plate-like body is not a glass plate but a transparent resin plate, the following disadvantages occur. That is, in general, a transparent resin plate is weaker in flexural rigidity than glass. In particular, when a transparent resin plate is used for the sunroof, the pressure on the outside of the vehicle when the vehicle is traveling is smaller than the pressure on the inside of the vehicle, and therefore the transparent resin plate tends to bend greatly toward the outside of the vehicle. Therefore, in order to increase the deflection rigidity of the transparent resin plate, a frame-shaped reinforcing member is provided on the inner surface of the transparent resin plate. In this case, a convex part is formed on the inner surface side of the peripheral part of the transparent plate-like body by utilizing the moldability of the transparent resin.
And a recessed part is formed in the position corresponding to a reinforcement member of a metal frame shape, and the recessed part of a reinforcing member is made to contact and latch to the convex part of a transparent plate-shaped body, and it is made to fix.
The inner surface of the peripheral edge of the transparent plate-shaped body and the metal frame-shaped reinforcing member are bonded with an adhesive.
Or between the peripheral part inner surface of a transparent plate-shaped body and a metal frame-shaped reinforcement member is fixed with a headed pin. At this time, a long hole extending in the direction of thermal expansion and contraction of the transparent plate-like body is formed on the reinforcing member side, and a mounting hole in which the leg of the headed pin is formed in the transparent plate-like body through the headed pin in the long hole. The reinforcing member is pressed against the transparent plate by the head of the headed pin by tightly fitting.
By doing in this way, it becomes possible to attach a metal frame-shaped reinforcement member with respect to a transparent plate-shaped body easily.
[0015]
In addition, when attaching a metal frame-shaped reinforcing member to the transparent plate using a headed pin, by forming a long hole in the reinforcing member, the transparent plate can be heated by changes in the outside air temperature. Even when it expands or contracts, it becomes possible to absorb the difference in thermal expansion between the reinforcing member and the transparent plate-like body.
[0016]

Correspondingly, the metal frame-shaped reinforcing member 25 is formed with a concave portion 27 that can contact the convex portion 26.
In addition, in FIG. 1, the convex part 26 of the peripheral part inner surface side of the transparent plate-shaped body 13 has two strips, and the concave part 27 of the metal frame-shaped reinforcing member 25 is W-shaped. It is not limited.
[0021]
Then, the inner surface of the peripheral portion of the transparent plate-like body 13 and the metal frame-shaped reinforcing member 25 are bonded with an adhesive. Alternatively, the headed pin 28 fixes between the inner peripheral edge of the transparent plate-like body 13 and the metal frame-shaped reinforcing member 25. When fixing with the headed pin 28, as shown in FIG. 2, a long hole 29 extending in the direction of thermal expansion and contraction of the transparent plate 13 is formed on the side of the reinforcing member 25, and The reinforcing member 25 is attached to the transparent plate 13 by the head of the headed pin 28 by tightly fitting the leg of the headed pin 28 into the mounting hole 30 formed in the transparent plate 13 through the head pin 28. Make it press.
[0022]
Next, the operation will be described.
First, since the weight of the transparent plate 13 can be reduced by changing the material of the transparent plate 13 to a transparent resin such as polycarbonate or acrylic, the vehicle can be reduced in weight and fuel consumption can be reduced along with the reduction in weight. It becomes possible.
In addition, since a transparent resin such as polycarbonate and acrylic has good moldability, it is not necessary to form a plate-like body having a uniform thickness like glass, and processing of various shapes can be performed on the peripheral portion. In this case, by injecting a transparent resin material into a mold for obtaining a predetermined shape, the following concave portions 15 and convex portions 26 can be formed on the peripheral edge portion of the transparent plate-like body. Furthermore, the hard coat layer 20 can be laminated on at least the outer surface of the transparent plate-like body 13 by providing the film 21 having the hard coat layer 20 in the mold.
[0023]
In the present invention, the concave portion 15 is formed on the outer peripheral side of the peripheral portion of the transparent plate-like body 13 made of resin such as polycarbonate or acrylic.
The upper and lower holding portions 17 and 18 are integrally provided at the upper and lower portions of the hollow portion 16, and the upper and lower holding portions 17 are provided with the resin frame body 14 having the convex portions 19. The upper and inner surfaces of the transparent plate-like body 13 are sandwiched between 17 and 18, and the convex portion 19 formed on the upper clamping portion 17 is fitted into the concave portion 15 of the transparent plate-like body 13. If necessary, by adhering both with a double-sided tape 24 provided between the peripheral portion of the transparent plate-like body 13 and the hollow portion 16 of the resin frame 14, without using a means such as resin injection, The resin frame body 14 can be easily attached to the peripheral edge portion of the transparent plate-like body 13. Even in the case of the present invention, it is also possible to attach the resin frame 14 using means such as resin injection as in the prior art.
Moreover, since the strength of attaching the resin frame 14 to the transparent plate-like body 13 is obtained by fitting the convex portion 19 and the concave portion 15, the upper clamping portion 17 is made thin and the transparent plate-like body 13 and the resin frame are attached. The level difference between the upper portion of the body 14 and the sandwiching portion 17 can be reduced to be substantially flush and the appearance can be improved.
[0024]
And the transparent plate-shaped body 13 is damaged by sticking the film 21 with the silicon-based or acrylic hard coat layer 20 formed on the outer surface of the resin-made transparent plate-shaped body 13 such as polycarbonate or acrylic. Can be difficult. At this time, if the edge portion of the film 21 covers the concave portion 15 of the transparent plate-like body 13, the resin frame body 14 may not be attached successfully. In addition, when the film 21 having the hard coat layer 20 is provided in advance in the mold of the transparent plate-like body 13 as described above, wrinkles are generated in the mold due to dimensional errors when the film 21 is cut. For prevention, the film 21 is required to be cut slightly smaller. Therefore, a film non-laminated portion 22 may be formed between the concave portion 15 on the outer surface of the transparent plate-like body 13 and the edge portion of the film 21.
Therefore, the film non-laminated portion 22 is protected by forming the fin portion 23 in the upper sandwiching portion 17 of the resin frame 14 so as to cover the film non-laminated portion 22. It becomes possible to prevent peeling.
[0025]
Further, the convex portion 26 is formed on the inner surface side of the peripheral edge of the transparent plate 13 by utilizing the moldability of a transparent resin such as polycarbonate or acrylic.
And the recessed part 27 is formed in the position corresponding to the metal frame-shaped reinforcement member 25, and the recessed part 27 of the reinforcement member 25 is made to contact | abut to the convex part 26 of the transparent plate-shaped body 13, and it fixes it.
In addition, in FIG. 1, the convex part 26 of the peripheral part inner surface side of the transparent plate-shaped body 13 has two strips, and the concave part 27 of the metal frame-shaped reinforcement member 25 is W-shaped. In this way, forming the convex portions 26 corresponding to the concave portions 27 so that the plurality of convex portions 26, particularly the concave portions 27 are W-shaped, can increase the flexural rigidity of the transparent plate-like body 13 made of resin. preferable.
[0026]
Then, the inner surface of the peripheral portion of the transparent plate-like body 13 and the metal frame-shaped reinforcing member 25 are bonded with an adhesive.
Alternatively, the headed pin 28 fixes between the inner peripheral edge of the transparent plate-like body 13 and the metal frame-shaped reinforcing member 25. At this time, as shown in FIG. 2, a long hole 29 extending in the direction of thermal expansion and contraction of the transparent plate 13 is formed on the reinforcing member 25 side, and the headed pin 28 is passed through the headed pin 28 in the long hole 29. The reinforcing member 25 is pressed against the transparent plate 13 by the head of the headed pin 28 by tightly fitting the leg portion into the mounting hole 30 formed in the transparent plate 13.
In this way, the metal frame-shaped reinforcing member 25 can be easily attached to the transparent plate-like body 13.
[0027]
Further, in the case where the metal frame-shaped reinforcing member 25 is attached to the transparent plate-like body 13 using the headed pins 28, a long hole 29 is formed in the reinforcing member 25, so that the transparent plate 13 is transparent due to changes in the outside air temperature. Even when the plate-like body 13 is thermally expanded or contracted, the difference in thermal expansion between the reinforcing member 25 and the transparent plate-like body 13 can be absorbed.
[0028]
In addition, this invention is not limited only to the above-mentioned embodiment, The transparent plate-shaped body concerning this invention is applicable also to window opening parts, such as a building other than a vehicle, In addition, it goes without saying that various modifications can be made without departing from the scope of the present invention.
