Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a glove compartment door opening / closing mechanism for opening / closing a compartment room recessed in an instrument panel of a vehicle.

[Prior Art] Conventionally, as shown in FIG. 5, a glove compartment door d pivotally attached to an instrument panel p by a hinge h is attached to a protruding piece t having one end protruding from a rear wall surface of the compartment chamber r. The coil spring s, which is locked and the other end is locked to a protruding piece d1 protruding from the inner surface of the door d, urges the door d in the opening and closing directions of the door d.
The glove compartment door d is held at the fully closed position by a stop wire w, one end of which is connected near the front end of the door d and the other end of which is connected to the side wall surface of the compartment r.

[Problem to be Solved by the Invention] In the above opening / closing mechanism, the coil spring s and the stop wire w move in and out of the compartment room r when the glove compartment door d is rotated to open and close the compartment room r. There is a problem that the effective storage volume of r decreases and that the number of parts increases and the cost increases.

An object of the present invention is to solve the above problems.

[Means for Solving the Problems] The opening / closing mechanism of the glove compartment door of the present invention is a back surface of the glove compartment door rotatably mounted on the instrument panel via a hinge to open and close the compartment chamber of the instrument panel. A spring stretched in an arc shape with its base end immovably locked near the opening of the compartment chamber and its front end locked near the free end of the grab compartment door. A line connecting the distal end of the spring and the hinge center of the grab compartment door during the rotation of the grab compartment door from the fully closed position to the fully open position is defined as the locking position of the base end of the spring. It has a configuration arranged so as to shift from the lower side to the upper side of the locking position of the base end of the spring .

[Operation] When the grab compartment door that opens and closes the compartment chamber is pivoted from the fully closed position to the vicinity of the fully closed position, the base end is locked near the opening of the compartment chamber, and the distal end is near the free end of the grab compartment door. A line connecting the front end of the spring attached to the back surface of the grab compartment door and the hinge center of the grab compartment door in a state of being locked and curved in an arc shape from above the locking position of the base end of the spring. When the grab compartment door moves downward and is urged in the closing direction, and when the grab compartment door rotates near the fully opened position, the line moves upward from below the locking position of the base end of the spring. The grab compartment door is biased in the opening direction, and the grab compartment door is fully opened When pivoted into position, the spring expands, reducing the spring force of the spring and holding the grab compartment door in the fully open position.

[Effects of the Invention] Since the present invention is configured as described above, the function of urging the grab compartment door in the closing direction and the opening direction, the function of defining the pivot end of the grab compartment door 1 in the opening direction, That is, since the function of holding the fully open position can be shared by one spring, there is no need for a fully closed lock means for holding the glove compartment door in the closed position or a fully open holding means for holding the glove compartment door in the fully open position. There is an effect that the number of parts of the mechanism can be reduced and the cost of parts can be reduced.

Also, since the spring is attached along the back surface of the grab compartment door and does not protrude into the compartment room when fully closed, it is possible to eliminate the problem that the effective storage volume of the compartment room is reduced and simplify the door opening and closing mechanism. There is an effect that the installation space can be reduced.

Next, an embodiment of the present invention will be described with reference to FIGS.

An upwardly open compartment chamber 5 which is opened and closed by a square plate-like grab compartment door 1 having a substantially arc-shaped cross section is formed in an instrument panel 4 installed in the cabin of the vehicle. A fixed protruding piece 6 whose upper end is disposed near the rear end of the opening 5b of the compartment chamber 5 protrudes upward at one end in the left-right direction at the upper part of the back wall surface 5a.

The grab compartment door 1 has a pair of hinges 3, 3 attached across the upper end of the inner wall surface 5 a of the compartment room 5 and the vicinity of the base edge of the grab compartment door 1.
Through the hinge center 3a to the instrument panel 4.
Is mounted so as to be rotatable in the vertical direction with a pivot point as a pivot point.

The linear spring 2 provided for urging the grab compartment door 1 in the closing direction near the fully closed position and in the opening direction near the fully opened position has a base end 2 a having a tip end of the fixed projection 6. Part is immovably locked and its tip
The two protrusions 6 and 1b are curved upward in an arc along the back surface of the door 1 while the movable protrusion 2b is engaged with the movable protrusion 1b protruding from the back surface near the free end 1a of the grab compartment door 1. It is stretched between. When the club compartment door 1 rotates, the tip 2b of the spring 2 has the hinge center 3a as the center of arc movement, and the tip 2b of the spring 2 and the hinge center 3a.
The circular movement is performed with the constant length line segment a connecting to 3a as the circular movement radius.

An indefinite length line segment b connecting the proximal end 2a and the distal end 2b of the spring 2
Is set so as to be shorter than the fixed length line segment a. The base end 2a of the spring 2 is connected to the fixed length line segment a of the spring 2 when the glove compartment door 1 is rotated to the fully closed position or near the fully closed position. When the grab compartment door 1 is shifted to a position below the locking position of the base end 2a and the grab compartment door 1 is rotated to the vicinity of the fully open position, the constant length line segment a is the base end 2a of the spring 2.
Of the spring 2 so that it moves to the upper side of the locking position of
The grab compartment door 1 is disposed between the hinge center h and a position between the hinge center h and the hinge center h.
During the rotation of the spring 2 from the fully closed position to the fully open position, the fixed length line segment a shifts from below the base end 2a of the spring 2 to above the base end 2a.

When the fixed-length line segment a shifts below the locking position of the base end 2a of the spring 2, the spring rig 2 is applied in the extension direction of the indefinite length line segment b connecting the base end 2a and the front end 2b of the spring 2.
Of the resilient force f, the vertical component force f1 orthogonal to the fixed length line segment a is directed downward to urge the grab compartment door 1 in the closing direction, while the fixed length line segment a is the base end of the spring 2. If it is shifted to the upper side of the locking position of 2a, the spring 2
Of the resilient force f, the vertical component force f1 orthogonal to the constant length line segment a is directed upward, and the grab compartment door 1 is urged in the opening direction. When the grab compartment door 1 is rotated to the fully open position, the spring 2 extends substantially linearly to reduce its resilience, and the pivot end of the grab compartment door 1 in the opening direction is defined.

Next, the operation and effect of the embodiment having the above configuration will be described.

In this example, a base end 2a is formed on the back surface of the glove compartment door 1 rotatably attached to the instrument panel 4 via the hinge 3 so as to open and close the compartment room 5 of the instrument panel 4. A spring 2 which is immovably locked in the vicinity of the portion 5b and whose tip 2a is locked in the vicinity of the free end 1a of the grab compartment door 1 is provided with a spring 2 which is curved and stretched in an arc shape. The locking position of the base end 2a is determined by the line a connecting the distal end 2b of the spring 2 and the hinge center 3a of the grab compartment door 1 while the grab compartment door 1 rotates from the fully closed position to the fully open position.
The base 2a is disposed so as to shift from the lower side to the upper side of the locking position.

For this reason, the function of urging the grab compartment door 1 in the closing direction and the opening direction and the function of defining the rotation end of the grab compartment door 1 in the opening direction can be shared by one spring, and the door opening / closing can be performed. There is an effect that the number of parts of the mechanism can be reduced and the cost of parts can be reduced.

Also, the spring 2 is the grab compartment door 1
Is installed along the rear surface of the compartment and does not protrude into the compartment room 5 when fully closed, so that the problem that the effective storage volume of the compartment room 5 decreases can be solved, and the door opening / closing mechanism is simplified to reduce the installation space. There is a possible effect.
