Description

[Detailed description of the invention] In the present invention, a pivoting piece 3 is extended from the top of the mounting piece 2 attached to the door mounting base 1 in a direction perpendicular to the mounting piece 2, and the upper side end of the door 4 is pivoted. A stopper pin 5a at the tip of a rotating rod 9 which is pivotally connected to the pivot piece 3 with a pivot pin 5 hanging downward from the pivot piece 3 and an arc-shaped elongated hole 8 bored in the side edge of the pivot piece 3. is provided to project downwardly from the elongated hole 8, and the stopper pin 5a is biased by a spring, so that when the door 4 is opened, the side end of the door 4 pushes the stopper pin 5a against the spring force. The purpose of this hinge is to determine the degree of opening of the door so that the door does not open more than a certain angle, but it also has a stopper for determining the degree of opening of the door. To provide a door mounting hinge which provides cushioning properties to the action and eliminates the possibility of impact being applied to the door.

In general, door mounting hinges that attach doors to washbasin units, etc., cannot determine the opening degree of the door, and there is a risk that the door will collide with other objects, especially if the door is made of enamel. There was a danger that the enamel would get damaged due to collision.

Therefore, as shown in FIGS. 1 and 2, a device having a protruding stopper pin 5a for setting the opening degree of the door 4 has been provided.

That is, in the conventional example shown in FIGS. 1 and 2, reference numeral 2 is a mounting piece having a plurality of mounting holes 6, 6, and a fan-shaped pivot piece 3 is provided extending from the upper end in a direction perpendicular to the mounting piece 2. Yes, mounting piece 2
A pivot pin 5 is provided vertically on the lower surface of the holder.

Furthermore, a plurality of insertion holes 7 are provided on the outer circumference of the fan-shaped pivot piece 3.
7 is bored, and a stopper pin 5a is inserted into the appropriate insertion hole 7.

The door mounting hinge is constructed in this way, and the mounting piece 2 is attached to the door mounting base 1, such as a cabinet, using a fixing device such as a screw, and the upper side end of the door 4 is rotatably pivoted. .

However, when the door 4 is opened as shown by the imaginary line in FIG. 1, the side edge of the door 4 hits the stopper pin 5a, and the door 4 will no longer open.

In this case, by changing the insertion position of the stopper pin 5 into the insertion holes 7, 7, the angle at which the door 4 opens can be changed within the range of 90 to 180 degrees.

However, in the conventional example shown in FIGS. 1 and 2,
Although it was possible to prevent the impact caused by the door 4 hitting other objects, the impact when the door 4 hit the stopper pin 5a was large, and there was a large risk that the door 4 itself would damage the stopper pin 5a, and the impact noise was also generated. The problem was that it was large and uncomfortable to use.

The present invention has been proposed in view of the above-mentioned points, and the present invention will be described in detail below with reference to embodiment figures.

FIG. 3 shows an embodiment of the present invention, in which a long hole 8 is bored on the outer periphery of a fan-shaped pivot piece 3, and a pivoting rod 9 is pivotally connected to the pivoting piece 3. The stopper pin 5a at the tip is made to protrude downward from the elongated hole 8, and the stopper pin 5a
is guided by a coil spring 10.

By doing so, when the door 4 is opened, the side end pushes the stopper pin 5a against the spring force of the coil spring 10, and has a cushioning property for the opening operation of the door 4. It is something that can be stopped.

As mentioned above, the door mounting hinge of this invention is designed so that the stopper pin that hits the side edge of the door when the door is opened protrudes downward, so when the door is opened, the side edge of the door hits the stopper pin. When the stopper pin hits, the door opens to a predetermined opening degree, and there is no risk of the door opening too much and hitting other objects unlike in the past, and the stopper pin is pivoted to the pivot piece. A stopper pin is formed as the tip of a rotating rod and projects downward from an arc-shaped long hole on one side edge for pivoting, and this stopper pin is biased by a spring, so that after the side edge of the door hits the stopper pin, The stopper pin is pushed against the spring force that biases the stopper pin, and the opening operation of the door can be stopped with a cushioning effect. This has the effect of not producing impact noise or damaging the door or stopper pin.

[Brief explanation of the drawing]

Fig. 1 is a plan view showing a conventional example, Fig. 2 is a perspective view showing the same hinge as above, and Fig. 3 is a perspective view of an embodiment of the present invention, in which 1 is a door mounting base and 2 is a mounting base. Piece 3 is the pivot piece, 4
5 is a door, 5 is a pivot pin, 5a is a stopper pin, 8 is a long hole, and 9 is a rotating rod.

Claims (1)
