Abstract

PURPOSE:To prevent a central part of a sun-visor from hanging down, by using a wire frame having bounce through which a long side part is expanded toward outside. CONSTITUTION:When a hand which held long side parts 11c and 11c under a state wherein the hand is positioned at the central part of the long side 11c of a wire frame 11 of a cylindrical pad 16 is released, bounce expanding toward outside is given to the long side parts 11c and 11c of the wire frame 11 and the cylindrical pad 16 is fitted over the central part of the long side part 11c of the wire frame in a press attaching state. When the wire frame 11 unified with the cylindrical pad 16 is placed between two sheets of the outer skins 17 and 17 and the external fringes 17a and 17b of these outer skins 17 and 17 are connected by high frequency welding with each other, assembly of a sun-visor B is completed. Even if the fixed sun-visor B is made horizontal, the cylindrical pad 16 is bounced toward the outside and kept under strained state by bounce F expanding toward the outside of the long side parts 11c and 11c of the wire frame 11 so that the pad 16 becomes flat at all times.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sun visor for a vehicle whose central portion does not sag.

2. Description of the Related Art Conventional vehicle sun visors include those shown in FIGS. 1 to 3, for example.

In the figure, reference numeral 1 denotes a wire frame of a vehicle sun visor A, which has a substantially rectangular shape, and both ends 1a and lb are inserted and fixed in a sandwiched state to a connecting member 2, which is, for example, a bent iron plate. An oval-shaped support shaft 3 is attached to the connecting member 2, and the support shaft 3 is rotatably attached to the ceiling 5 of the vehicle via a base 4.

A rectangular wire frame 1 with both ends 1a and lb connected by a connecting member 2 has two plate-shaped pads 6 made of hard foam resin such as urethane foam or vinyl chloride foam.
．． It is sandwiched between 6. Furthermore, the two plate-shaped pads 6, 6 sandwiching the wire frame 1 are sandwiched between two skins 7, 7 made of vinyl chloride, and the outer peripheries of these skins 7, 7 are welded by high frequency. Therefore, these skins 7, 7 are formed into a bag shape and cover the plate-shaped pad 6. Reference numeral 8 denotes a hook provided on the ceiling 5, which locks a part of the wire frame 1 exposed to the outside by cutting out the skin 7 and the plate-shaped pad 6.

However, in such a vehicle sun visor, the plate-shaped pad 6 sandwiching the substantially rectangular wire frame 1 is formed of a soft foamed resin such as urethane foam or vinyl chloride foam, and therefore lacks rigidity. The center part of the plate-shaped pad 6 sags due to its own weight, and the outer skin 7 is also made of vinyl chloride, which lacks rigidity. If the vehicle sun visor A is made horizontal, there is a problem in that the central portion of the vehicle sun visor A hangs down to the floor, that is, to the bottom.

Therefore, the substantially rectangular wire frame 1 sandwiched between the plate-shaped pads 6.6 is made of an elastic material, and the long sides of the wire frame 1 are bulged out compared to the regular shape before being sandwiched between the plate-shaped pads 6.6. It was considered that the long side part would apply a biasing force to expand outward by making it substantially rectangular when sandwiched between the plate-shaped pads 6.degree.6. However, in this case, as shown by the two-dot chain line in FIG. 2, the long side of the wire frame l moves out of the predetermined position sandwiched between the plate pads 6 and 6 due to the applied biasing force. , the outer skin is urged to spread in the width direction, but this urging force does not act to increase the rigidity of the plate-like pad 6.6.
Similarly to the above, it has not been possible to solve the problem that the central portion of the plate-like pad 6 sags due to its own weight.

This invention was made by focusing on such conventional problems, and it is a wire formed of an elastic body whose long sides are given an urging force to expand outward when the wire is made into a substantially rectangular shape. A frame, a wire frame inserted into the hollow part, a cylindrical pad that is deformed into a flat shape by the biasing force of the wire frame and crimped to the center of the wire frame, and a wire frame to which the cylindrical pad is crimped is covered. It is an object of the present invention to solve the above-mentioned problems by providing a sun visor for a vehicle that is made of a skin that is transparent.

The present invention will be explained below based on the drawings.

FIGS. 4 to 7 are diagrams showing one embodiment of the present invention.

First, to explain the configuration, in the figure, reference numeral 11 is a wire frame made of an elastic body, and both ends 11a, ll
b is inserted and fixed in a sandwiched state to a connecting member 12 which is a bent iron plate. In the free state, the long side portions 11c and Ilc of the wire frame 11 are formed in a swollen state than in the normal rectangular state, a portion of which is shown by broken lines in FIG.

An oval-shaped support shaft 13 is attached to the connecting member 12, and the support shaft 13 is rotatably attached to the ceiling 5 of the vehicle via a base 14.

Reference numeral 16 denotes an elastic cylindrical pad made of rubber, and a wire frame 1 is provided in the hollow part of the cylindrical pad 16.
1 is inserted. At this time, the wire frame 11 is regulated by the cylindrical pad 16 and deforms from the swollen state to the normal rectangular shape, and the long sides 11c and llc of the wire frame 11 have attachments that expand outward. power is given. The cylindrical pad 16 is fitted into the center of the wire frame 11 in a crimped manner. In the figure, 16a and 16b are deformed cylindrical pads made of 16
is the same as

As shown in FIG. 4, the wire frame 11 with the cylindrical pad 16 integrated therein is viewed from both sides with two approximately rectangular skins 17 and 17 that are slightly larger than the wire frame 11.
The outer peripheral edges 17a, 17 of these epidermis 17.17
The vehicle sun visor B of this embodiment is formed by joining parts a by high-frequency welding. Therefore, the wire frame 1 is formed by the skin flap 7 formed into a bag shape by high frequency welding.
1 and plate-shaped pad 16 are coated. Reference numeral 18 denotes a notch hole formed in each skin 17 to expose a portion of the wire frame 11.

Next, how to assemble the vehicle sun visor B will be explained.

First, the wire frame 11 made of an elastic body is made to be in a more swollen state than its normal, approximately rectangular shape. The long side portion 11c of the wire frame 11.

11c is held by hand, and the wire frame 11 is inserted into the hollow part of the cylindrical pad 16 with the distance between the long sides 11c and llc in between, and the wire frame 11 is shaped into a substantially rectangular shape. Then, the cylindrical pad 16
When the wire frame 11 is located at the center of the long side 11c, the hands holding the long side 11c, llc are released. Then, the long side portion 11c of the wire frame 11.

11c is given a biasing force to expand outward, and a cylindrical pad 16 is provided at the center of the long side 11c of the wire frame.
is fitted in a crimped state.

Next, the wire frame 1 with the cylindrical pad 16 integrated
1 is sandwiched between two epidermis 17.17, and these epidermis 17゜1
When the outer peripheral edges 17a, 17a of 7 are joined by high frequency welding, assembly of the vehicle sun visor B is completed.

The assembled vehicle sun visor B is attached to a vehicle by connecting the built-in connecting member 12 to the support shaft 13 attached to the ceiling 5 of the vehicle via the base 4 in an inserted state.

Vehicle sun visor B attached to the vehicle in this way
Even if it is leveled by flipping it up to the ceiling 5 or rotating it toward the windshield side, the cylindrical pad 16 will not touch the long sides 11c and l of the wire frame 11, as shown in FIG.
The biasing force F that expands toward the outside of lc always biases the lc toward the outside so that it becomes flat, and is maintained in a tensioned state. In addition, the cylindrical pad 16 and the wire frame 1
The outer skin 17 covering the sun visor B is also biased by the wire frame 11 through the cylindrical pad 16 and maintained in a tensioned state, so that the central portion of the vehicle sun visor B does not sag.

In this embodiment, the cylindrical pad 16 is made of elastic rubber, but the wire frame 16 may be made of non-elastic material such as flexible synthetic resin or resin.
Since the tension state is maintained by receiving the urging force of 1, it goes without saying that the material may be made of a material that does not have elasticity.

As described above, according to the present invention, the sun visor for a vehicle is made of a wire frame formed of an elastic body that is given a biasing force that causes the long sides to expand outward when the vehicle sun visor is made into a substantially rectangular shape. and a hollow part; the wire frame is inserted, and the cylindrical pad is deformed into a flat shape by the biasing force of the wire frame and crimped to the center of the wire frame, and the cylindrical pad is crimped. Since the structure consists of a skin covering the wire frame, when the vehicle Sannovazer is raised to the ceiling or rotated toward the windshield and laid horizontally, it becomes a cylindrical shape with the wire frame inserted into the hollow part. The pad is constantly biased by the outwardly expanding biasing force generated on the long side of the wire frame to maintain a tensioned state, and the outer skin is also biased by the wire frame via the cylindrical pad to maintain an even tension. Since the tensioned state is maintained, it is possible to prevent the central part of the vehicle sun visor from sagging.
