Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in an opening / closing device for a box body whose opening / closing movement is controlled by a string-type air damper, such as a grab box pivotally supported on an instrument panel of an automobile.
[0002]
[Prior art]
This type of conventional opening / closing device pivotally supports a grab box in a space in an instrument panel of an automobile, while fixing a string-type air damper cylinder on the back or side of the grab box, It is the structure which fixes the string connected to the piston of the damper to the corresponding instrument panel side.
[0003]
For this reason, in the conventional opening and closing device, it is possible to smoothly control the opening and closing movement of the grab box due to the presence of the string type air damper, but on the other hand, the air damper is attached to the grab box. There is a risk that the internal volume of the grab box may be sacrificed in relation to fixing to the back surface or the side surface from the outside.
[0004]
Therefore, as shown in Japanese Utility Model Laid-Open No. 6-67769, a cylinder of an air damper is integrally formed on the inner wall of the grab box, and the air damper is installed on the inner inner side of the grab box. An improved version has been proposed that simplifies installation and minimizes the sacrifice of the internal volume of the grab box.
[0005]
[Problems to be solved by the invention]
Therefore, in this improved switchgear, it is possible to minimize the sacrifice of the internal volume of the grab box by installing a cylinder integrally on the inner wall of the grab box. On the other hand, when the tip of the string connected to the piston of the air damper is fixed to the instrument panel side because the air damper is installed on the back side of the grab box, it is more than the installation position of the air damper. Because it has to be fixed to the back side of the instrument panel, especially when removing the grab box for maintenance, etc., there was a problem that it was difficult to attach and detach the tip of the string to the instrument panel. .
[0006]
[Means for Solving the Problems]
The present invention was developed in order to effectively solve the problems of such an improved switchgear, and the invention according to claim 1 has a bucket shape whose upper side opens on the support structure side, and its front surface. In the box body opening / closing device that controls the opening / closing movement of the box body with a string-type air damper by pivotally supporting the lower part of the box body that is opened by pulling the side forward, the front side of the box body is The air damper is configured by an outer member and an inner member, and the air damper is installed in a space defined between the two members, and the tip of the string connected to the piston of the air damper is connected to the side wall of the box body. The structure which fixed to the support structure side through the opening was employ | adopted.
[0007]
The invention described in claim 2 is based on the premise of claim 1 and adopts a configuration in which the air damper is installed in a horizontal state inside the front opening edge of the box body.
[0008]
The invention described in claim 3 is based on the premise of claim 1 and adopts a configuration in which the air damper and the opening / closing lock means of the box body are covered together by the inner member.
[0009]
Therefore, in the invention described in claim 1, since the air damper is installed in the space defined between the outer member and the inner member constituting the front side of the box body, The tip of the string connected to the piston of the damper can be fixed to the front side of the support structure as much as possible. When removing the box body for maintenance, etc., the string tip is detached from the instrument panel. As the air damper itself can be repaired or replaced, the box body can be opened and the workability is improved.
[0010]
In the invention of claim 2, the air damper is horizontally installed inside the front opening edge of the box body, whereby the opening edge of the box body is strengthened as a double structure of the outer member and the inner member. As a result, the strength and rigidity of the box body itself is improved and it is hardly affected by temperature. In the invention described in claim 3, since the air damper and the opening / closing lock means of the box body are covered together by the inner member, the appearance of the box body in the opened state is particularly improved.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, if the present invention is described in detail based on a preferred embodiment illustrated, the opening and closing device according to the embodiment also includes a grab box that is pivotally supported in a space of an instrument panel of an automobile. Although it was developed as a target, it is characterized by the following configuration.
[0012]
First, for the grab box B, which is a box body, a string-type air damper 10 is installed inside the front opening edge of the bucket shape. In this installation, as shown in FIG. A plurality of bosses 2 are integrally projected on the back surface of the front decorative plate 1 which is an outer member of the grab box B, and the engagement pieces 12 formed on the cylinder 11 of the air damper 10 are engaged with the bosses 2. Thereafter, the cover body 3 serving as an inner member is put on the cover body 3 and the cover body 3 is screwed to the front decorative plate 1 so that the inside of the front opening edge of the grab box B is shown in FIGS. As shown, the air damper 10 is installed in a horizontal state in a space S defined between the front decorative plate 1 and the cover body 3.
[0013]
The cover body 3 which is the inner member is formed to have a size that covers the inside of the front opening edge of the grab box B over the entire area, but is engaged with and disengaged from the striker 7 provided on the instrument panel side. Since the open / close lock means 4 is also intended to be installed in the space S that simultaneously defines the air damper 10 and the open / close lock means 4, the cover body is put together inside the front opening edge of the grab box B. 3, there is no fear of harming the appearance of the grab box B in the open state.
[0014]
Further, as shown in FIG. 4, the string-type air damper 10 itself includes a cylindrical cylinder 11 having both ends opened, a piston 13 to which the proximal end of the string 14 is connected and moved in the cylinder 11, and a cylinder. 11, a guide cap 15 that guides the movement of the string 14 on one end opening side, an end cap 18 with a valve 17 that opens and closes a communication hole 16 opened in the other end opening of the cylinder 11, A compression coil spring 19 interposed between the guide cap 15 and the piston 13 is provided, and the distal end portion 14a of the string 14 is drawn out from an opening 5 formed in one side wall of the grab box B, The free length of the instrument panel shall be extended with a margin for assembly with the instrument panel. .
[0015]
Next, for the instrument panel P as a support structure, the string-type air damper 10 is installed inside the front opening edge of the grab box B, and as shown in FIG. Since it becomes possible to provide the groove-like fixing portion 6 for hooking and fixing the tip portion 14a on the front side of the empty space, when removing the grab box B from the instrument panel P side for maintenance or the like, the tip of the cord 14 The attachment and detachment of the part 14a with respect to the fixed part 6 of the instrument panel P becomes easy. Moreover, since the structure which attaches an air damper to the instrument panel P side becomes unnecessary, the instrument panel P side is simplified.
[0016]
Therefore, under the opening / closing device having such a configuration, the grab box B is pivotally supported in the empty space of the instrument panel P, and at the same time, the distal end portion 14a of the string 14 of the air damper 10 is attached to the instrument panel P. When the grab box B is set in a state where it is hooked on the fixing portion 6 and the engagement of the opening / closing lock means 4 with the striker 7 is released and moved in the opening direction, the string 14 is gradually pulled out from the cylinder 11 of the air damper 10. Since the piston 13 moves in the same direction against the spring pressure of the compression coil spring 19, the flow resistance of air passing through an orifice (not shown) established on the piston 13 side is With the air damper effect, it is ensured that the grab box B slowly moves to the open state as shown in FIG.
[0017]
Moreover, in the open state of the grab box B, as shown in the drawing, the air damper 10 and the opening / closing lock means 4 installed on the opening edge thereof are covered together by the cover body 3, so that the appearance of the glove box B can be improved. Not only is there no fear of harm, but in this state, if the cover body 3 as the inner member is removed, the air damper 10 can be repaired or replaced immediately.
[0018]
Conversely, when the grab box B is moved in the closing direction, the piston 13 is forcibly pushed back into the cylinder 11 by the spring pressure of the compression coil spring 19 together with the string 14, and into the cylinder 11. The accumulated air escapes from the end cap 18 side to the outside through the communication hole 16 opened by the valve 17, so that the piston 13 moves quickly in the cylinder 11 and facilitates the closing operation of the grab box B. As shown in FIG. 7, the closed state of the grab box B is guaranteed.
[0019]
In the present embodiment, installing the air damper 10 in the space S defined between the front decorative plate 1 and the cover body 3 of the grab box B means that at least the opening edge of the grab box B is double. Since it is strengthened as a structure, the strength and rigidity of the grab box B itself are improved, and it is difficult to be affected by temperature. Furthermore, since the string 14 drawn out from the opening 5 on the side wall of the grab box B is concealed by the side edge of the front decorative board 1 projecting outward from the side wall, there is no fear of disturbing the appearance.
[0020]
【The invention's effect】
As described above, according to the present invention, the air damper is installed in the space defined between the outer member and the inner member constituting the front surface side of the box body under the first aspect by adopting the above configuration. As a result, it is possible to fix the tip of the string connected to the piston of the air damper to the front side of the support structure as much as possible, and when removing the box body for maintenance etc., the tip of the string This makes it easy to attach / detach the instrument to / from the instrument panel, and when the air damper itself is repaired / replaced, the box body can be opened and the workability is improved.
[0021]
Under claim 2, since the air damper is horizontally installed inside the front opening edge of the box body, the opening edge of the box body is strengthened as a double structure of the outer member and the inner member. Its strength and rigidity are improved, and it is hardly affected by temperature. Under the third aspect, since the air damper and the opening / closing lock means of the box body are covered together by the inner member, the appearance in the opened state of the box body is improved.
