Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Use) The present invention relates to an opening / closing device for an opening / closing body such as a vehicle door or an engine hood, and more particularly to an opening / closing device for holding the opening / closing body in two open positions.

(Prior Art) As a conventional opening / closing device of this type, for example, FIGS.
Some are shown in the figure. (Refer to Japanese Patent Laid-Open No. 58-4673) For the opening and closing body shown by this engine hood (hereinafter referred to as the hood), the hood is opened for inspection work in the engine room, but for normal inspection, the open position shown by the solid line. Although the hood is opened and closed, when a special opening degree for heavy maintenance work (eg engine attachment / detachment) is required, the normal opening degree is insufficient, so that the structure can be further opened as indicated by the one-dot chain line.

In the figure, 1 is a hood, 2 is an engine room, 3 is a rotation fulcrum of a hood 1 hinged to a vehicle body 24, 4 is a gas stay, 5 is a rod, 6 is a bracket provided on the back surface of the hood 1, and 7 is an L-shape. -Shaped slide hole, 8 is windshield glass, 11 is a support portion of the gas stay 4, 13 is a vehicle body 24
Shows the pivot point at which the gas stay 4 is pivotally supported.

I is the slide hole 7 of the bracket 6 with the end 5a of the rod 5 of the gas stay 4 in the normal open position (first opening) of the hood 1.
1 shows an open position in which the hood 1 is held by being engaged with one end portion (a). (See FIG. 7) II is the gas stay 4 with the hood at a special open position (second opening).
The open position in which the hood 1 is held by engaging the end 5a of the rod 5 with the other end (b) of the slide hole 7 of the bracket 6 is shown. (Refer to FIG. 8) (Problems to be solved by the invention) In the case of the conventional opening / closing device, the hood 1 is normally opened.
In order to hold (I) and the special open position (II), the slide hole with which one end 5a of the gas stay 4 slides and engages is formed in an L-shape or a U-shape. The slide hole is bent so that it can be held at each end of the shape of a square. Therefore, the bracket width (a) has to be wide and large.

However, when the width of the bracket 6 is wide, when the hood 1 is opened and closed, the amount of the bracket projecting to the back side of the hood 1 is large, which hinders the opening and closing of the hood 1. Also, the bracket 6
Since it is large, it may interfere with the engine and the like in the hood when it is closed, which may limit the space in the engine room 2.

Therefore, the present invention was devised in order to eliminate the above-mentioned drawbacks, and its purpose is to provide an opening / closing device for an opening / closing body in which the bracket width on the rear surface of the engine hood is reduced while maintaining the conventional opening / closing mechanism of the hood. It is provided.

(Means for Solving the Problems) In order to achieve the above object, a feature of the present invention is that a bracket having a linear slide hole is provided on one of a vehicle body and an opening / closing body, and one end of a gas stay is provided on the other side. Is slidably supported in the slide hole, and the other end is pivotally supported,
In addition, a stopper is provided so as to be rotatable around the axis of the gas stay.

(Operation) To hold the opening / closing body in the open position with the first opening, one end of the gas stay is engaged with one of the slide holes, and in order to hold the open position with the second opening, slide one end of the gas stay. The other end of the hole was engaged, and the stopper was rotated from the gas stay and brought into contact with the end of the bracket, and the end of the gas stay and the stopper held between the end of the slide hole of the bracket and the end of the bracket.

(Embodiment) An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 4.

Reference numeral 1 denotes an engine hood, the rear end of which is hinged to the vehicle body 24 so that the front can be opened and closed. Reference numeral 16 is a bracket provided on the back surface of the hood 1. A straight slide hole 17 is formed in the bracket 16 so that the bracket width (b) is narrower than the conventional width (a). A gas stay 14 is provided with a supporting portion 11 on one side and a rod 15 extending and contracting on the other side. The supporting portion 11 pivotally supports a vehicle body 24 at a pivot point 13 so that the end portion 15a of the rod 15 is rotatable. It is slidably engaged with a slide hole 17 of the bracket 16. Further, on the bracket 16 side of the gas stay 14, as shown in FIG. 5, a Z-shaped stopper 20 whose end portion 20a is in contact with the end surface 16a of the bracket 16 is rotatably attached to the cylindrical surface of the gas stay 14. Reference numeral 26 is a resin washer which facilitates rotation of the stopper 20 provided in the gas stay 14.

The end surface 16 of the bracket 16 that abuts the stopper 20
a is the end face 20a of the stopper 20 when fully opened as shown in FIG.
An inclined surface is formed so as to be in close contact with. In the figure, 8 is a windshield glass and 2 is an engine room.

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

First, the engine hood 1 is in the closed position (one-dot chain line in FIG. 1).
Therefore, to open the first opening (I) which is a normal opening and hold the hood 1, the front end of the hood 1 is lifted by hand, and the rod 15 is projected by the elastic force of the gas stay 14,
The hood 1 is biased in the opening direction, and the hood 1 is easily lifted. Then, as shown in FIG. 2, the end portion 15a of the rod 15 engages with one end portion (a) of the slide hole 17 of the bracket 16. In this case, the stopper 20 is rotated to a position where it does not interfere with the bracket 16.

Next, the engine hood 1 is opened at a second opening (I
To open to I), if the hood 1 is further lifted from the open position (I) of the first opening, the rod 15 is pushed into the gas stay 14 against the elastic force of the gas stay 14, and the rod 15 The end portion 15a is a slide hole 17 of the bracket 16.
Sliding inside to the other side, the end 15a of the rod 15 engages with the other end (b) of the slide hole 17.

Next, the stopper 20 provided on the gas stay 14 is rotated along the cylindrical peripheral surface of the gas stay 14 to remove the stopper 2 from the stopper 2.
The tip 20a of 0 is brought into contact with the end surface 16a of the bracket 16 to maintain the second opening of the hood 1. As shown in FIG. 3, the end 15a of the rod 15 and the stopper 20 hold the end of the slide hole 17 of the bracket 16 and the end surface 16a of the bracket 16 from each other. The reason for holding the rod in this manner is that the rod 15 moves to the one end (a) side in the slide hole 17 by the elastic force of the gas stay 14 and works to return to the first opening side.

Thus, the hood 1 is held at the second opening (II).

Further, since the stopper 20 and the rod 15 sandwich between the end opening of the slide hole 17 of the bracket 16 and the end surface 16a of the bracket 16, the hood 1 does not open any further, and the stopper 20 prevents the bracket 16 from being opened. It does not come off easily.

In the present invention, the opening / closing body is described as the engine hood, but the invention is not limited to this, and can be applied to a rear door, a trunk lid, and even a door. Further, the turning point of the support portion of the gas stay is not limited to the vehicle body side, and it goes without saying that it may be provided on the opening / closing body side.

(Effect of the device) As described above, according to the present invention, the bracket is provided with the long hole-shaped slide hole so that the width of the bracket provided on the back surface of the opening / closing body is narrowed and the protruding amount is reduced, so that the opening / closing body is not obstructed. The amount of interference on the vehicle body side due to the bracket when the opening / closing body is closed is reduced, and the layout in the engine room is facilitated. or,
There is no risk that the opening / closing body will open further when the opening / closing body is fully opened (the second opening degree), or the stopper will easily come off to close the opening / closing body.

Further, the stopper has a simple shape and is easy to manufacture.
