Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arm structure of a lid in which the texture is improved by increasing the rigidity when the lid is opened in a predetermined state.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 6, in a vehicle such as a large-sized or medium-sized bus, an article using an instrument panel is provided on the left side of a driver's seat a in a vehicle forward direction. A storage section b is formed, and the upper surface of the article storage section b is covered with a lid (lid) c.

The lid c can be opened and closed by reciprocating in a vertical plane about a hinge d whose center of rotation extends in the vehicle width direction as a fulcrum. A lid arm e is provided on one side in the width direction.

Therefore, when the lid c is opened to the upper limit position, the lid arm e is locked by a lock mechanism (not shown), so that the lid c is supported by the lid arm e.

[0005]

However, if the lid c is large and the lid arm e is provided only on one side as shown in FIG. 6, the rigidity of the lid c on the side where the lid arm e is not provided is provided. Therefore, there is a problem that the lid c vibrates in an open state and the texture is poor.

Further, if a sheet metal insert is inserted into the lid c in order to increase the rigidity of the lid c, there is a problem that the weight and the cost of the lid c are increased.

Further, if the lid arm e is provided not only on one side of the lid c but also on both sides to form a double arm, a lock mechanism (not shown) provided on each of the lid arms e when the lid c is opened. There is a case that it does not hang on the predetermined position and hangs, or it only hangs on one side,
Also in this case, there is a problem that the texture of the lid c in the open state is poor.

The present invention has been made in view of the above-described circumstances, and provides a lid arm structure that increases the rigidity when the lid is opened and improves the texture without increasing the weight or cost as much as possible. It was done for the purpose.

[0009]

The arm structure of the lid according to the present invention is such that the lid is opened on one side in the width direction of a lid provided so as to be opened and closed by rotating in a vertical plane in the article storage section. A lid arm having a lock mechanism for supporting the lid so as not to be lowered when the lid is at a predetermined position, and a friction arm provided on the other side in the width direction of the lid to apply resistance to the lid opened by frictional force. It is a thing.

When the lid is opened, one side of the lid is supported by a lock mechanism of the lid arm, and the other side of the lid is supported by resistance due to frictional force of the friction arm. For this reason, when the lid is opened, it feels as if the rigidity of the lid is increased, and the sense of rigidity is increased, and the texture is improved.

Further, since the friction arm has a simple structure, there is little increase in weight and cost.

And the storage unit bottom surface 1 as well as the storage unit side walls 1b on both sides in the vehicle width direction.
The storage portion side wall 1b is integrally connected to both sides of the storage portion inner wall 1a in the vehicle width direction at the front end in the vehicle forward direction, and the storage portion bottom surface 1c is connected to the storage portion at the front end in the vehicle forward direction. It is integrally connected to the lower end of the back wall 1a, and is integrally connected to the lower end of the storage portion side wall 1b on both sides in the vehicle width direction.

A bracket 3 is screwed to the upper part of the storage part inner wall 1a on the side facing the article storage part 2, and fitted to the upper end of the bracket 3 so that the axis extends in the vehicle width direction. A lid 6 is pivotally attached to the horizontal pin 4 via a bracket 5 so that the lid 6 can rotate up and down on a vertical inner surface.

The lid 6 has a substantially L-shaped cross section. When the lid 6 is closed so as to cover the article storage section 2, the upper surface thereof is a flat plate having a slightly arcuate shape upward, and the rear of the vehicle 6 in the forward direction of the vehicle is a vehicle. It has a shape that is inclined downhill toward the rear in the forward direction.

A horizontal pin 8 parallel to the horizontal pin 4 is fitted to a bracket 7 fixed to a required position on the lower surface on one side in the vehicle width direction of the lid 6, and the horizontal pin 8 extends downward and has a lower end. A friction arm 9 having a predetermined thickness and having a stopper 9a is pivotally mounted as a lid arm.

The friction arms 9 have radii of curvature R1, R2 projecting rearward in the vehicle forward direction with respect to the center of the horizontal pin 4 on both sides in a direction parallel to the vehicle forward direction.
(R2> R1) is formed in an arc shape, and a curvature radius R3 having a diameter slightly larger than the curvature radius R2 over a required range is provided at an upper end portion on the curvature radius R2 side which is the outer diameter side of the friction arm 9.
Is provided so as to form a concentric arc with respect to the portions of the radii of curvature R1 and R2.

A rectangular cylindrical arm guide 10 is mounted on the upper surface of the side wall 1b of the storage section on which the friction arm 9 is provided.
Extends downward through the arm guide 10.
It is located below.

A guide member 11 for guiding the friction arm 9 by contacting the small diameter side of the friction arm 9 is mounted inside the arm guide 10, and the friction arm 9 is contacted by contacting the large diameter side of the friction arm 9. A spring 12 that applies a frictional force to the friction arm 9 by pressing it against the guide member 11 is attached.

A spring 13 is attached to the lower end of the friction arm 9, and a locking member 14 is mounted below the spring 12 inside the arm guide 10 so that the spring 13 can be locked. I have. Thus, a locking mechanism is constituted by the spring 13 and the locking member 14, and when the lid 6 rotates to the upper limit position, the spring 13 is locked to the locking member 14 and bent,
The repelling force allows the lid 6 to be locked so as not to lower naturally. The position where the spring 13 and the locking member 14 are provided is not limited to the position illustrated in FIG. 2, but may be a position obtained by changing the angle by 90 degrees with respect to the position illustrated in FIG. 2. Also, a locking member 14 is attached to the friction arm 9,
A spring 13 may be attached to the arm guide 10.

1 and 3 on the other side of the lid 6 in the vehicle width direction.
The friction assist arm 15 is provided as shown in FIG. That is, an arm 17 is pivotally attached to the bracket 16 attached to a required position of the lower surface of the lid 6 on the other side in the vehicle width direction, and the bracket 17 is provided on the upper surface of the storage portion side wall 1b on the other side in the vehicle width direction. Has an arm 19 pivotally connected to a pin.

The opposite ends of the arms 17 and 19 are pivotally connected by horizontal pins 20 having both ends parallel to the horizontal pins 4 and 8, and an angle θ formed by the arms 17 and 19 is provided.
The arms 17 and 19 can rotate relative to each other so that (see FIG. 3) changes.

As shown in FIG. 5, a substantially oval-shaped member 21 is housed in a chamber 19a having a substantially oval-shaped front shape provided in a penetrating portion of the horizontal pin 20 of the arm 19, similar to the chamber 19a. The arm 17 is externally fitted to the pin 20, and a horizontal pin 20 is provided on a surface of the arm 17 opposite to the arm 19.
The plate spring 22 is disposed in a state of being fitted to the outside.

A hole is formed in the arm 17 at a phase of 180 degrees around the horizontal pin 20, and a steel ball 23 is fitted into the hole so as to contact the member 21 and the leaf spring 22. I have. Thus, a frictional force can be applied to the contact surface between the arms 17 and 19 by the elastic force of the leaf spring 22.

Although not shown, the arms 17 and 19 are provided with stoppers for preventing the arms 17 and 19 from being excessively opened.

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

For example, as shown by a virtual line in FIG. 2, when the lid 6 is closed, the friction arm 9 is closed.
Is lowered to the lower limit position, the friction increasing portion 9b is sandwiched between the spring 12 and the guide member 11, and the arms 17 and 19 of the friction assist arm 15 are folded most, and the angle is as small as θ1 as shown in FIG. It has become.

To open the lid 6, a person turns the lid 6 by hand in the opening direction. For this reason, the lid 6 rotates upward about the horizontal pin 4 as a fulcrum as shown in FIGS.

At this time, the friction arm 9 is urged by the spring 12 and pressed against the guide member 11,
A frictional force is generated between the contact surface between the friction arm 9 and the guide member 11 and the contact surface between the spring 12 and the friction arm 9.
5, a leaf spring 22 is provided on the contact surface between the arms 17 and 19.
Generates a frictional force.

When the lid 6 is opened to the upper limit position, the spring 13 at the lower end of the friction arm 9 moves the arm guide 1
0 locking member 14, and as a result, the spring 13
Of the friction arm 9 by the spring 13
The arm 17 and the arm 19 are supported by the frictional force on the friction assist arm 15 side.

Therefore, the lid 6 is locked by receiving a certain resistance as a whole in the opened state, as if the rigidity increased and became uniform, and the lid 6 was supported in a well-balanced manner without vibrating as a whole. Therefore, the rigidity of the lid 6 in the opened state is increased, and the texture is improved.

When the lid 6 is opened, the friction arm 9 rises together with the lid 6 while being guided by the arm guide 10, and in the friction assist arm 15, the angle between the arms 17 and 19 gradually increases from θ1 to θ. . At this time, the member 21 rotates integrally with the arm 19.

When the lid 6 is closed, the lid 6 is closed by hand.
Press down. Then, the spring 13 is disengaged from the locking member 14, and thereafter, the lid 6 is rotated downward by its own weight with the horizontal pin 4 as a fulcrum. At this time, since the frictional force is generated by the friction arm 9 and the friction assist arm 15, the lid 6 receives the resistance and descends at a slow speed.

When the lid 6 is lowered to a position immediately before the lid 6 is completely closed, the friction increasing portion 9b of the friction arm 9 is sandwiched between the spring 12 and the guide member 11, so that the frictional force increases and the resistance increases. As a result, the lid 6 is decelerated and closed smoothly. Therefore, the texture when closing the lid 6 is further improved.

Since the friction assist arm 15 is small and has a simple structure, the weight and cost are not significantly increased.

In the embodiment of the present invention, a case has been described in which a friction assist arm having two bendable arms is used. However, when the lid is opened and closed, friction is applied to the lid by frictional force. Arms of various structures can be used if the arm is used.The lid arm is a friction arm, but even if it is not a friction arm, any arm that can be locked when the lead is opened to the upper limit can be used. It goes without saying that various changes can be made without departing from the spirit of the invention.

[0039]

According to the lid arm structure of the present invention,
Various excellent effects can be obtained, such as an increase in the rigidity of the lid in the open state, an increase in the rigidity, an improvement in texture, and no increase in weight and cost.
