Abstract

PROBLEM TO BE SOLVED: To improve the rigidity of hinge sections by constituting a lid device of a cover section and a pair of hinges integrally formed in the cover section and bridging a reinforcing member between the free end sections of both hinges. SOLUTION: The external shape of the lid device 24 is composed of a cover section 25 and a pair of hinges 26 integrally formed to the cover section 25. Fitting projections 27 are projected from the free end sections of each hinge 26, and the lid device 24 is molded of a PP resin. A reinforcing member 29 is bridged between the free end sections of both hinges 26-that is, on the axis of rotation of the lid device 24, and a section between the free end sections of both hinges 26 is connected. The reinforcing member 29 has strength increasing rigidity in the cross direction of both hinges 26 while simultaneously having elasticity, in which the reinforcing member 29 is bent properly when a certain constant force is applied by a finger and the reinforcing member is pinched. Accordingly, the rigidity of the hinges is improved while the unstable state of pitches between the hinges by deformation at the time of molding can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a lid device.

[0002]

2. Description of the Related Art Some vehicles, such as scooter type vehicles, whose body is covered with a cover have a fuel filler port and an inspection port covered with a lid (lid). Such a lid is normally attached to the cover via a hinge so as to be freely opened and closed. Also,
As a material of the lid, a synthetic resin such as an ABS resin having relatively high hardness is used.

[0003] As a method of attaching the lid to the cover, a pair of hinges formed integrally with the lid are sandwiched between fingers using the elasticity of the lid, and the distance between the hinges is reduced to fit the fitting portion on the cover side. I was matching.

[0004]

However, when the lid is used for a fuel filler, the ABS resin needs an oil-resistant treatment, which leads to an increase in cost, which is not preferable.

On the other hand, a scooter type vehicle or the like often uses a colored molded product of PP resin for its body cover, and it is desired to use the same material for the lid in order to improve the appearance.

However, since the PP resin has a relatively low hardness, the rigidity of the hinge is low, and the pitch between the hinges is not stable due to deformation during molding, so that the PP resin tends to come off the cover.

Therefore, there is a method of increasing rigidity by mixing talc or the like into the PP resin, but it is not preferable because the appearance differs from the surrounding body cover. It is also possible to use the hinge as a separate part using a different material having high rigidity, but this increases the number of parts and the number of assembling steps, resulting in an increase in cost.

The present invention has been made in view of the above circumstances, and has as its object to provide a lid device which has a simple structure and improves the rigidity of a hinge portion.

[0009]

According to a first aspect of the present invention, a lid device and a pair of hinges formed integrally with the lid portion are provided to solve the above-mentioned problems. And a reinforcing member is provided between the free ends of the hinges.

In order to solve the above-mentioned problem, the reinforcing member is bent in a U-shape, and the apex of the bent portion is sandwiched between the both hinges from outside. In this case, it is attached in such a manner that it is oriented in a direction to be bent.

Specifically, the cover element includes a leg shield cover 15, a rear leg shield 16, an upper frame cover 17, a lower frame cover 18, and the like.

A U-shaped rear leg shield 16 is provided near the center of the vehicle body 1, and the front side of the rear leg seal stands upright. The leg shield cover 15 is arranged from the front to the lower part of the rear leg shield 16. The rear leg shield 1
6 has an inspection port 19 accessible to the front of the unit swing type engine 11 and is covered with a maintenance lid 20 that can be freely opened and closed.

On the other hand, an upper frame cover 17 is provided around the rear frame 4 so as to surround the right and left sides of the rear frame 4, and a pair of left and right lower frame covers 18 is provided below the upper frame cover 17, and a rear end portion is provided at the rear end. A rear combination lamp 21 is provided. The cover elements 15 to 18 are formed of a synthetic resin material, for example, a PP resin.

Further, an operation seat 22 also serving as a lid is disposed above the article storage room 5. Driving seat 2
2 is configured to be openable and closable via, for example, a hinge (not shown) provided at a lower front portion thereof, and is configured to be lockable by a seat lock device (not shown).

FIG. 2 is a perspective view of the upper frame cover 17 as viewed obliquely from behind. As shown in FIG. 2, a fuel supply port 23 that can access the fuel and lubricating oil tank 6 is formed on the rear upper surface of the upper frame cover 17, and is closed by a lid device 24.

FIG. 3 is a plan view of the lid device 24,
FIG. 4 is a left side view of the same. As shown in FIGS. 2 to 4, the outer shape of the lid device 24 includes a lid 25 and a pair of hinges 26 formed integrally with the lid 25. The hinge 26 extends, for example, rearward and rearward from the rear surface of the lid portion 25, and is provided apart from the vehicle width direction.

A fitting projection 27 is provided at the free end of each hinge 26.
Are protruded outward in the vehicle width direction. These fitting projections 27 are rotatably fitted to fitting parts (not shown) formed near the oil supply port 23, and the lid part 24 is supported by the fitting part as a shaft so as to be openable and closable.

The lid 25 is provided with a lock device 28, and the lid device 24 is configured to be lockable. And
The lid device 24 is formed of the same material as the other cover elements 15 to 18, in this embodiment, PP resin.

A reinforcing member 29 is provided between the free ends of the hinges 26, that is, on the axis of rotation of the lid device 24.
The free ends of both hinges 26 are connected. This reinforcing member 2
Numeral 9 has the strength to increase the rigidity in the width direction of both hinges 26, and also has the elasticity to bend appropriately when being pinched by applying a certain force such as a finger. In this embodiment, a rib-like plate having a width of about 5 mm and a thickness of about 2 mm is used.

Further, the reinforcing member 29 is formed in a state of being bent in a "-" shape. When the reinforcing member 29 is installed between the free ends of the hinges 26, the vertex 3
0 is oriented in a direction in which the two hinges 26 are desired to bend when the fingers are pinched from the outside, that is, in a direction that does not interfere with members around the fitting portion formed in the vicinity of the filler port 23.

Next, the operation of the present embodiment will be described.

The lid device 24 is attached to the upper frame cover 17 by using the elasticity of the hinges 26 to pinch both hinges between the fingers, for example, to reduce the distance between the hinges 26 and to fit the fitting portion on the upper frame cover 17 side. The hinge 26 returns to its original position by releasing the finger, and the fitting protrusion 27 fits into the fitting portion.

Since the PP resin used for the lid device 24 has relatively low hardness, it is easy to reduce the interval between the hinges 26. In addition, the reinforcing member 29 provided between the hinges 26 solves the problem of low rigidity of the hinge 26 made of PP resin and unstable pitch between the hinges 26 due to deformation during molding.

Further, the reinforcing member 29 may bend when both hinges 26 are pinched from outside by fingers, and may interfere with members around the fuel filler 23. The above-mentioned problem can be solved by bending and attaching the apex 30 of the bent portion in a direction in which the bending is desired.

Although the above-described embodiment shows an example in which the present invention is applied to the lid device 24 that covers the fuel and lubricating oil supply port 23, the present invention employs the inspection port 19 formed in the rear leg shield 16 as an example. It is of course applicable to the maintenance lid 20 to be covered. Further, the above-described embodiment shows an example in which the present invention is applied to the scooter type vehicle 1. However, the present invention is sufficiently applicable as long as it has a lid device that can be opened and closed.

[0030]

As described above, according to the lid device of the present invention, in the lid device including the lid and the pair of hinges formed integrally with the lid, the two hinges are free. Since the reinforcing member is provided between the ends, the rigidity of the hinge is increased, and the pitch between the hinges is prevented from becoming unstable due to deformation during molding.

Further, the reinforcing member is bent in a U-shape,
Since the vertices of the bent portion are oriented in the direction in which the two hinges are desired to bend when the hinges are sandwiched from the outside, it is possible to prevent the reinforcing member that bends when the lid device is attached from interfering with surrounding members. .
