Abstract

An opening and closing mechanism of an automotive flip-up glass is provided to open the flip-up glass while the convex shape of the leaf spring is transformed into the concave shape. An opening and closing mechanism of an automotive flip-up glass comprises a leaf spring(50) which is attached to the upper side of a glass hinge base(21). When a hinge arm(22) is opened around a hinge(22a), a convex upper side of the leaf spring is transformed into the concave shape. The leaf spring includes lateral flanges which are formed so that it is mounted on the glass hinge base; a vertical unit which protrudes vertically in the inner side of both lateral flanges; and a convex portion connecting two vertical units. The convex part is elliptical. The upper end of the hinge arm contacts with the convex part so that a flip-up glass(30) is opened when the hinge arm rotates around the hinge.

Description

Opening and closing apparatus of flip up glass for automobile}

The present invention relates to an opening and closing device of a car flip-up glass, and more particularly, by installing a leaf spring on the hinge arm and the glass hinge base of the flip-up glass for opening and closing the flip-up glass by the force of the leaf spring It relates to an opening and closing device of flip-up glass.

In general, a tail gate is an open or closed door installed at the rear of a wagon type vehicle or a van and a recreational vehicle so that cargo can be stored behind the vehicle body.

These tailgates are installed to facilitate the driver's access to the cargo compartment formed in the interior of the vehicle. By attaching the tailgate to the rear of the vehicle, passengers can easily load or unload cargo in the cargo compartment and also get on and off the passengers at the rear of the vehicle. You can do that.

In addition, a flip-up glass is installed on the upper part of the tailgate to observe the rear end of the vehicle and to identify the goods loaded in the interior of the vehicle from the outside. Flip-up glass that can be opened and closed is also proposed and used to easily load cargo.

That is, as shown in FIGS. 1 and 2, the open / closeable flip-up glass is hingedly coupled to a glass hinge 20 having an inclined outward angle to the tailgate 10 and the glass hinge. Flip-up glass 30 is coupled to the 20 through a separate fixture (31).

Referring to the configuration of the glass hinge 20 in detail, the glass hinge 20 is a glass hinge base 21 is fixed to the tail gate 10 through a plurality of fasteners 21a, and the glass hinge base It is made of a glass arm 22 coupled to the hinge (22a) to the 21, the flip-up glass 30 is to be fixed to the glass arm 22 through the fixture 31 described above.

The flip-up glass 30 is opened and closed while rotating by the gas lifter 32 supported at both sides.

Therefore, loading and unloading of the cargo could be easily performed through the flip-up glass 30 having such a configuration.

In the conventional opening and closing device for a flip-up glass for automobiles configured as described above, the glass hinge base 21 and the hinge arm are connected to the glass hinge 20 by the force of the gas pressure of the gas lifter 32 by the operation of the glass handle after the key is unlocked. 22 opens the flip-up glass 30 by the rotational movement with each other.

However, the opening and closing device of the conventional flip-up glass for automobiles configured as described above has a structure in which the opening degree of the flip-up glass 30 is controlled by the gas lifter 32, so that the user can There is a problem that the flip-up glass 30 is damaged if the amount of open space is the same when the storage space is insufficient. In addition, there is a problem in that the manufacturing cost due to the use of the gas lifter 32 is increased.

The present invention is to solve the problems as described above, an object of the present invention is to install a leaf spring on the hinge arm and the glass hinge base of the flip-up glass flip car for opening and closing the flip-up glass by the force of the leaf spring It is to provide an opening and closing device of the up glass.

Accordingly, the present invention has been made to solve the object as described above, the opening and closing device of the flip-up glass for automobiles according to the present invention, the glass hinge base is fixed on the tailgate, the hinge hinge to the glass hinge base In the opening and closing device for a car flip-up glass made of a glass arm moving around the hinge while fixing the flip-up glass via a fastener, the hinge arm is attached to the upper surface of the glass hinge base It is characterized in that it is provided with a leaf spring that is deformed into a concave shape when the upper surface is in contact with the convex shape.

According to the opening and closing device for a car flip-up glass of the present invention as described above, in opening and closing the flip-up glass by rotating the hinge arm equipped with the flip-up glass around the hinge, the upper end portion of the hinge arm opening and closing operation The convex shape of the leaf spring deforms into a concave shape as it contacts, and when it is closed, the flip-up glass is opened. On the contrary, the concave shape is released and the convex shape is released. And, there is an effect of suppressing the increase in the cost of opening and closing the flip-up glass by the conventional gas lifter.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

Figure 3 is a cross-sectional view showing the opening and closing device of the flip-up glass for automobiles of the present invention, Figure 4 is an exploded perspective view showing the opening and closing device of a flip-up glass for automobiles of the present invention, Figure 5 is a leaf spring of the present invention It is a perspective view shown.

3 to 5, the opening and closing apparatus of the flip-up glass for automobiles of the present invention, the glass hinge base 21 on the tailgate 10, the hinge 22a on the glass hinge base 21 The glass arm 22 is coupled to the glass arm 22 moving around the hinge 22a while fixing the flip-up glass 30 through the fastener 31, and is attached to an upper surface of the glass hinge base 21. When the hinge arm 22 is opened about the hinge 22a and contacts the convex shape of the upper surface, the hinge arm 22 is formed of a leaf spring 50 that is deformed into a concave shape.

The leaf spring 50 has both flanges 51 formed at both ends thereof to be mounted to the glass hinge base 21, and a vertical portion 52 protruding perpendicularly to the inner surface of the flanges 51. The two vertical parts 52 are connected to each other, and are formed in an elliptical shape that is convex upward, so that the hinge arm 22 rotates about the hinge 22a to open the flip-up glass 30. The upper end is made of a convex portion 53 in contact.

The convex portion 53 is deformed into a concave shape 53a when the upper end of the hinge arm 22 is opened in contact, and is deformed into the convex portion 53 when the pressing is released.

Next, when the flip-up glass 30 is opened as shown in FIG. 3 in the opening / closing device of the flip-up glass for automobiles of the present invention, the hinge arm 22 on which the flip-up glass 30 is mounted may open the hinge 22a. When rotated in the counterclockwise direction, the upper end of the hinge arm 22 comes into contact with the upper surface of the convex portion 53 of the leaf spring 50 fixed to the glass hinge base 21. If the hinge arm 53 continues to rotate, the convex portion 53 of the leaf spring 50 opens upward while being deformed into a concave shape 53a. On the contrary, when the pull-up glass 30 is pulled and closed toward the front side of the user, the hinge arm is deformed into the shape of the convex convex portion 53 while the state in which the concave shape 53a of the leaf spring 50 is pressed is released. A force is applied to the upper end of the 22, so that the flip-up glass 30 is easily closed even if a small force is applied.

The opening and closing device for a car flip-up glass for automobiles according to the present invention described above is one preferred embodiment, and the present invention is not limited to the above-described embodiment, and is claimed in the following claims. Without departing from the technical spirit of the present invention to the extent that any person skilled in the art to which the present invention pertains various modifications can be made.
