Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinge having a catch function.

Conventional products of this type have two parts extending from the base.
A swinging piece is attached to each protruding end of the book connecting rod, and an opening/closing door is attached to the swinging piece. When opening and closing the opening/closing door, the door is pressed against the edge of the furniture frame near the closed position, and the door is pressed against the edge of the furniture frame when it is opened. In this position, a spring force is applied to the two connecting rods so that the open state is maintained. In addition, in the conventional configuration, a spring is attached to the parallel link mechanism itself, which consists of the base side, the swinging side, and two connecting rods connecting them, so that the swinging piece moves from the door closed position to the door open position. In the process, the shift in the position of each pivot point of the parallel link is captured and the dead center is completely configured, so the correlation between the setting of the position of the swinging piece with respect to the base and the arrangement position of the spring is extremely close. This has the disadvantage that it becomes complicated and, as a result, the base itself becomes bulky.

Therefore, the object of the present invention is to provide a hinge with a catch function of an extremely simple structure, in which one of the connecting rods is partially fully protruded and the displacement thereof is used to set the dead center. Furthermore, the present invention allows the spring receiving surface provided on the protruding portion of the connecting rod to be disposed in a wide range of locations, and at the same time, the construction is made such that even a thin material on the structural side thereof can have a strong structure. It is an object of the present invention to provide a hinge with a catch function that has a structure that allows the hinge with the above-mentioned simple structure to be further reduced in weight and has a longer life.

The first connecting rod 4 and the second connecting rod n are installed in parallel as shown in Figures Q and S, and the swinging piece 27 is connected to the base 9.
It is designed to be able to swing from side to side. 1st above
The fastening points at both ends of the second connecting rods 4 and 32 are such that when the door 7 is closed, the inner surface of the base side of the door 7 faces the front surface of the side frame 3 with almost no gap, as shown in FIG. When the door 7 is opened approximately 90 degrees, the end surface 7a of the door 70 is positioned to face the front surface of the side frame 3. In addition, the base 90
The door 7 is attached to the second connecting rod located on the side closer to the base by approximately 90 mm.

A stopper is formed so as to come into contact with B and prevent further opening of the door 7.

Next, A, 36 is a projecting portion formed on the free end of the connecting side plate O, 33 on the base side of the second connecting rod n, and as shown in the figure, it is a stop to the pivot 33a on the base side. It protrudes far beyond the landing point. a is Haride County.

The support shaft installed at the tip is a resin collar fitted to the support shaft W, and the spring contact point 38a is formed by its surface. Next, addition is a spring support shaft attached to the extension part 21 of the base 9, and both side plates η.

It is constructed between η. Chrysanthemum is a torsion spring illustrated as a spring in which the torsion portion 40a is fitted into the spring support shaft as shown in Figure 8;'. One end of the above torsion spring 4
0b is brought into contact with the connecting plate part of the take-out part 4, and the other end part 40G of the torsion spring is brought into contact with the spring fork point 38a of the cuff field, as shown in FIGS. 7 and 3. . The above torsion spring 40
The positional relationship between the spring fork point 38a is such that the swing piece I is
The positional relationship is such that when the spring prong point 38a is in the closed position, the spring fork point 38a is biased in the door closing direction A, and when the swing piece η is in the fully open position of the door 7, it is biased in the door 7 opening direction B. is set to . That is, when the opening angle θ of the door 7 is small as shown in FIG.
When the opening angle θ of the door 7 is large as shown in FIG. The spring is biased clockwise or in a direction by the spring force of the torsion spring chrysanthemum.

In the structure described above, when the door 7 is completely closed, the other end 40C of the torsion spring cutout is in the second position as shown in FIG.
This second connecting rod 3 is pressed by pressing the spring fork point 38a of the connecting rod.
2 is biased in the counterclockwise direction, so this second connecting rod
urges the swinging piece 27 in the clockwise direction and applies a force in the closing direction to the door 7. Therefore, the door 7 is reliably maintained in a completely closed state and has a catch function. Next, when it is desired to fully open the door 7, the door 7 can be opened by pulling the door 7 toward the user against the urging force of the torsion spring cutter. In this case, when the door 7 is opened, the pivot 33b of the second connecting rod is rotated counterclockwise around the pivot 3tJb2 of the first connecting rod 4, and the second connecting rod is rotated around the pivot 33a. Since it is rotated in the clockwise direction, the spring fork point 38a that comes into contact with the torsion spring shaft is gradually brought closer to the spring support shaft. When the door 7 is wide open to the position shown in FIG. 3, the spring fork point 38a reaches the dead center, and when the door 7 is opened any further, the torsion spring moves the second connecting rod to the pivot point 33a. It will be biased clockwise around . Therefore, after that, the door 7 is biased toward the opening side by the torsion spring, and the door 7 can be opened even if the user releases his/her hand from the door 7. The opening operation of the door 7 is stopped when the opening angle θ of the door 7 reaches approximately 90 degrees, when a part of the stopper of the second connecting rod comes into contact with the pivot aOa, and in this fully open state, the door 7 is stopped by the torsion spring. Since the door 7 is biased toward the opening side, the door 7 is maintained in a completely open state. Next, when it is desired to close the door 7, the door 7 can be closed by pushing the door 7'ft toward the closing side against the biasing force of the torsion spring cut. In this case, door 7 is the third
If the door 7 is closed beyond the state shown in the figure, the spring force of the torsion spring 40 will bias the door 7 toward the closing side again as shown in Figure μ. Can be closed completely closed.

FIG. 70 shows a different embodiment of the second connecting rod, in which the half of the connecting side plate portion 33 on the substantially pivot shaft 33b side in the above embodiment is formed integrally with the connecting arm portion 32a. It should be noted that parts that are functionally the same or equivalent to those in the previous figure are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted.

As described above, in this invention, the frame edge inner surface 3b of the furniture 1
A swinging piece 27 is fixed to the inner surface of the opening/closing door, and two connecting rods are arranged in parallel to the base 9, which is fixed to the base 9.

Since the door is connected by wings, the swinging piece 27 attached to the door 7 swings relative to the base 9 to open and close the door, and as a result, it has the effect of functioning as a hinge.

Moreover, in the present invention, the free end of the base side of the @2 connecting rod is extended to a large extent, and its tip is made into a spring fork point 38a, and the spring 40 is brought into contact with this, and the above-mentioned rocking piece When the door I is in the closed position, the force of the spring is applied in the direction of maintaining the closed state (in the direction of the arrow), and as the door 7 is gradually opened, the splash point aSa reaches the dead center. Since the force of the spring ω is applied in the opposite direction, that is, in the direction of opening the door, if the user operates the door until it is close to closing, the spring force will close the door and keep it there. The catch function of doing so can be demonstrated.

In addition, when the user opens the door, it has the advantage of maintaining the open state (1).

A further advantageous feature of the present invention is that the spring fork point 38a is provided at an extension of the free end of the second connecting rod on the base side. To be more specific, since the free end of the second connecting rod on the base side is made to protrude and all of it is used as the spring fork point 38a, the position of the spring 40 in contact with the above-mentioned fork point 33a and the above-mentioned fixing point are different. As a result, even if the overall shape of the base is made extremely small, the catch function described above can be provided inside the base.

Moreover, the second connecting rod blade consists of two parallel members.

It is made up of two parts, and is integrated with a member style, and furthermore, a roller holder is provided between the two members O and 33 as a spring holder, so these members simply function usefully as a link mechanism. It is not bulky and has the advantage of being very strong in the horizontal direction, that is, in the structure that holds the door.
