Abstract

PURPOSE:To effect locking under an opening state and effect closing under gravity and to release a locking state through one action by a method wherein the pin of a stay is engaged with the notch part of the slide hole of a bracket. CONSTITUTION:A stay 1 is coupled to a cover, and a bracket 2 having a slide hole 2a is secured to the central part of the upper side of a base. A leaf spring 5 (folded in two stages) is mounted on the bracket 2, and notch parts 2b and 2c are formed in the central part and the right end part, respectively, of the slide hole 2a. In which case, when a cover is opened, the pin of the stay 1 is moved through the force of the leaf spring 5 and engaged with the notch part 2c and brought into a locked state in the position. In release of locking, the cover is pressed down by hands and the pin presses the leaf spring 5, and the pin is disengaged from the notch part 2c. When the cover is further pressed down, the pin is slid and engaged with the notch part 2b and brought into a locked state again. When the cover is consecutively further pressed down, the pin of the notch part 2b is disengaged and slid to close the cover.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a cover for a terminal device that is opened and closed, and more particularly, the present invention relates to a cover for a terminal device that is opened and closed, and more particularly, a cover stay that is stopped at each of an open position and a closed position, and a lock and a lock provided on the cover stay. The present invention relates to a cover for a terminal device that has a leaf spring that automatically releases the lock and does not close under its own weight when the lock is released.

2. Description of the Related Art FIG. 4 is a side view showing a cover stay as an example of a cover for a conventional terminal device, and FIG. 5 is a sectional view taken along the line B--B in FIG.

[0003] As shown in FIGS. 4 and 5, when the cover of a conventional terminal device is opened (not shown),
The body 11c of the pin 11b provided at the lower end of the stay 11 attached to the cover falls under its own weight into the notch 12b at the right end of the slide hole 12a of the bracket 12 attached to the base of the terminal device (not shown). When closing the cover, lift the stay 11 by hand and lock the body 1 of the pin 11b.
1c is removed from the notch 12b of the bracket 12, the lock is released, and the cover is lowered.

[Problems to be Solved by the Invention] As described above, when closing the cover of a conventional terminal device from an open state, it is necessary to lift the stay by hand to release the lock and then close the cover. Depending on where the terminal device is installed, it may be difficult to unlock the stay. In addition, since the operation of closing the cover is a two-step operation of unlocking the stay and closing the cover, it is necessary to have both a hand to unlock the stay and a hand to close the cover, making the operation cumbersome. There is also.

[0005]

[Means for Solving the Problems] The cover of the terminal device of the present invention includes a cover that can be opened and closed with respect to a base using a lower end as a fulcrum, and a stay that is rotatably coupled to the lower side of the cover at the upper end. , a bracket having a slide hole in the center and fixed to the upper side of the base; a pin provided at the lower end of the stay and sliding in the slide hole of the bracket; A notch portion into which the pin fits is provided at the upper right end of the slide hole of the bracket.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing details of section C in FIG. 2, FIG. 2 is a side view showing an embodiment of the present invention, and FIG. 3 is a side view showing details of section C in FIG.
It is an A-line sectional view.

In FIGS. 1 to 3, a stay 1 is rotatably connected to a cover 4 at a fulcrum 1a at its upper end. The cover 4 opens and closes with respect to the base 3 using a fulcrum 3a at the lower right end as a fulcrum. A bracket 2 having a slide hole 2a in the center is fixed to the upper side of the base 3, and a pin 1b provided at the lower end of the stay 1 is fitted into the bracket 2 so that it can slide inside the slide hole 2a. There is. Therefore, when the cover 4 is opened using the fulcrum 3a as the fulcrum, the pin 1b of the stay 1 slides in the slide hole 2a of the bracket 2.

A leaf spring 5 is attached to the bracket 2 and is bent into two stages at the center and right end so as to come into contact with the lower surface of the pin 1b as the stay 1 moves. In addition, the slide hole 2a of the bracket 2
Cutouts 2b and 2c are provided at the center and right end of the holder, which are cut upward so that the pin 1b can be inserted thereinto.

[0010] The cover of the terminal device configured in this way is
When the cover 4 is fully opened (position 4a), the pin 1b of the stay 1 is pushed up by the leaf spring 5, fits into the notch 2c of the slide hole 2a of the bracket 2, and is locked in that position. . To release the lock, push down the cover 4 by hand. As a result, the pin 1b pushes down the bending point 5a at the right end of the leaf spring 5, so that the pin 1b comes off from the notch 2c and the lock is released. When the cover 4 is further pushed down by hand, the pin 1b comes to the position of the notch 2b of the slide hole 2a, and is pushed up by the leaf spring 5 to fit into the notch 2b of the slide hole 2a. It is locked again in position (position 4b). In order to completely close the cover 4, push it down further by hand from this position. As a result, the pin 1b pushes down the bending point 5b at the center of the leaf spring 5 and comes off the notch 2b, thereby releasing the lock. In this way, the cover 4 pushes up the pin 1b of the stay 1 by the leaf spring 5, so unless it is pushed down by hand until it passes through the notch 2b in the center of the slide hole 2a of the bracket 2, it cannot be pushed up by its own weight. It has a structure that does not close.

[0011]

[Effects of the Invention] As explained above, the terminal device cover of the present invention is provided with a leaf spring that pushes up the pin of the stay, and the force of this leaf spring pushes the pin of the stay into the notch provided in the slide hole of the bracket. By fitting the cover into the opening, it is possible to lock the cover in an open state and prevent it from closing under its own weight, and it is also possible to release the locked state in one step.
