Description

[Detailed description of the invention] Industrial application field The invention mainly relates to a hinge fitting for hinged doors of sinks, cupboards, etc. so that they can be opened and closed freely, and prevents the doors from opening naturally when they are closed. The feature is that a temporary fixing mechanism is integrated into the device.

Prior Art Conventional hinge fittings merely support the door so that it can be opened and closed, and in order to hold the door in the closed state, male and female temporary fittings that engage like a snap are attached to the container side and the door side. When the door is closed, the female and male fittings engage to achieve the purpose of temporarily fixing the door.

However, with the conventional technology as mentioned above,
Since the temporary fittings have to be prepared separately, not only is the cost inevitably high, but when installing the door, it is necessary to install male and female temporary fittings in addition to installing the hinge fittings, and both temporary fittings are necessary. Since the two are engaged when the door is closed, great care must be taken in setting the mounting position.

Purpose of the invention The purpose of the invention is that by integrally incorporating the temporary fixing mechanism into the hinge metal fitting, the temporary fixing mechanism for the door can be temporarily fixed by simply using the hinge metal fitting of the present invention to hinge the door so that it can be opened and closed. At the same time, the above-mentioned problems caused by the conventional technology are solved, the manufacturing cost is reduced, and the efficiency of the door installation work is greatly improved.

Configuration of the invention The configuration of the invention will be explained in detail with reference to the drawings as follows.

In the figure, reference numeral 1 denotes a fixing horizontal board, and a mounting piece 2 having set screw insertion holes a and a is integrally bent and vertically provided on the rear edge thereof. Reference numeral 1a denotes a horizontally elongated guide hole opened approximately at the center of the horizontal base plate 1, and the shaft portion 3a of the stopper slide 3 located on the lower surface of the horizontal base plate 1 is movable in the left-right direction in FIG. It is fitted.

1b is an escape guide hole opened near the rear end of the horizontal board 1; 1c is a spring receiving piece protruding in front of the guide hole 1b; 4 is a tip end connected to the upper end of the shaft portion 3a of the stopper slide 3; A guide piece 4a connected to the base end of the spring housing casing is bent toward the lower surface of the relief guide hole 1b and is slidably fitted into the guide hole 1b. . Reference numeral 5 denotes a spring housed in the casing 4, the tip of which is engaged with the front inner wall of the casing 4, and the rear end of which is engaged with the receiving piece 1c. Therefore, the stopper slide 3 attached to the tip of the casing 4 is given a sliding force to the left in FIG. 4 based on the repulsive force of the spring 5.

Reference numeral 6 denotes a movable piece pivotally attached to the tip of the above-mentioned fixed horizontal substrate 1 via a pivot 7,
The movable piece 6 is made up of a horizontal plate-shaped stopper piece 6a parallel to the horizontal fixing board 1, and a door mounting piece 6b integrally bent so as to hang down from the rear edge of the stopper piece 6a. The mounting piece 6b has a door mounting set screw insertion hole b.
The required number of holes have been drilled. Moreover, the stopper slider 3 mentioned above is provided at the end of the stopper piece 6a.
A guide tapered edge m for receiving the slider 3 and a stopper tapered edge n for stabilizing the slider 3 in the receiving state are formed (see FIG. 3).

Function When the present invention having the above configuration is applied to a sink door, for example, the fixing horizontal substrate 1 is attached to the sink side via the mounting piece 2, and the door A is attached to the sink door.
are attached to the attachment pieces 6b of the movable piece 6 as shown in FIG. 5, and these attachments are made to the upper and lower ends of the door A.

Through this invention, the door A is hinged so that it can be opened and closed freely.
Although it is opened and closed in exactly the same way as a normal door, when the door is tightly closed, the tip of the stopper piece 6a of the movable piece 6 is locked against the stopper slide 3. As a result, door A is automatically temporarily secured, and spontaneous opening of the door is effectively prevented. That is, just before the door is completely closed, the guiding tapered edge m of the stopper piece 6a collides with the slider 3 and pushes it against the spring 5 into the fourth position.
After sliding the slider 3 to the right in the figure, when the slider 3 reaches the tapered edge n for the stopper, the slider 3 returns to its original position along the tapered edge n based on the repulsive force of the spring 5. , a good locking condition will be maintained. Therefore, the movable piece 6 is engaged with the fixing horizontal substrate 1 side, and thereby the door A can be temporarily fixed in the closed state.

Incidentally, when opening the door, by pulling the door A a little forcefully, the stopper tapered edge n pushes the slider 3 sideways against the spring 5, and this can be easily achieved.

Effects of the Invention According to the present invention described in detail above, the temporary fixing effect when the door is closed can be achieved by simply supporting the door so that it can be opened and closed in the same way as conventional hinge fittings. Therefore,
Compared to the conventional case where temporary fixing fittings are provided separately, the door installation work is not only significantly simplified, but also the manufacturing cost is reduced.

Further, in the present invention, a stopper slider 3 is slidably attached to the fixed horizontal base plate 1 for engaging with the stopper taper edge n formed at the tip of the stopper piece 6a, and the slider 3 Since this is configured to be connected with an appropriate spring in order to bring it into elastic pressure contact with the tapered edge n for the stopper, the temporary fixing action can be achieved extremely smoothly and reliably based on the presence of the tapered edge n for the stopper. Become.

Furthermore, the present invention is configured so that the horizontal plate-shaped stopper piece 6a of the movable piece 6 is positioned parallel to and overlapping with respect to the fixed horizontal base plate 1, so that the entire structure can be made compact and the door and container can be separated. Even if the gap is extremely small, the installation will be permitted. In order to elastically press the stopper slide 3 against the stopper tapered edge n, a spring 5 is provided on the outer surface of the fixing horizontal base plate 1, so the spring 5 The presence of the fixing horizontal substrate 1 and the horizontal plate-shaped stopper piece 6a do not interfere with the above-mentioned overlapping parallel arrangement.
