Description

  The present invention is a slide hinge for opening and closing a door of furniture, storage, building, etc., and in particular, a slide hinge in which a biasing force acts in the direction of pushing back the door in the final narrow angle region where the door is closed. About.

The slide hinge is mounted on the inner side of the mounting arm, in which the cup attached in a state of being embedded in the vicinity of one end on the back side of the door and the mounting arm having a substantially bowl shape are connected by the first link and the second link. The mounting arm can be attached to and detached from the mounting seat attached to the inner wall surface of the door opening through the mounting unit with one touch.
In many of the conventional slide hinges, a spring base having a substantially V-shape in a side view is fitted and supported on a pin supporting the first link and the mounting arm, and one end of the spring is attached to the mounting arm. The other end of the spring is brought into contact with the surface near the front end of the mounting arm side of the back plate surface of the second link so that the sliding hinge does not rattle. There is a smooth opening and closing of the door.
When the door is attached to the door using the slide hinge, the locking member and the receiving member locked to the locking member are used together to maintain the door's closed posture, and the door is closed. Engagement by the member and the receiving member is performed to keep the door closed. The door is opened and closed by manually operating a handle attached to the door.

The doors of many recent kitchen storages and storages at the bottom of the vanity are attached by slide hinges so that they can be opened and closed.
However, these storages are often located in low positions where you have to bend and operate, or you can't reach the handle unless you stretch your back and raise your hand. In women, the handle may be out of reach.
For this reason, it is troublesome to bend or stretch your back and raise your hand, and many people open the door by hooking the edge of the door with your fingertips. This operation is not easy for short women and women with weak fingertips who need a certain amount of force, and young women may hurt their nails.

A slide hinge for solving such a problem has already been disclosed (see Japanese Patent Application Laid-Open No. 2004-339927 below).
This slide hinge has two links (which are described as a box element in Patent Document 1) and an attachment arm (which is described as an arm in Patent Document 1) ( (It is described as a rocker in Patent Document 1.) A cam-shaped protrusion is provided at the tip of the link located outside the contact, and one end of a spring having a V-shape is brought into contact with the protrusion. The urging force acts in the direction of pushing back the door in the final narrow angle region where the other end of the door is brought into contact with the inner surface of the mounting arm (arm) to close the door.
According to Patent Document 1, the protrusions are made of plastic (see FIGS. 1 and 11 of Patent Document 1) inserted into the tip of the link (rocker) and the center of the tip of the link (rocker) is a tongue. One that projects in a piece shape (see FIGS. 15, 16, and 17 of Patent Document 1) has been proposed.
JP 2004-339927A (FIGS. 1, 11, 15, 16, and 17)

However, like the slide hinge described in Patent Document 1, when a plastic protrusion is attached to the tip of the link (rocker), a strong force is applied to the protrusion by a spring, causing damage or cracking of the protrusion. There is a risk of problems such as protrusion wear due to long-term use and damage due to deterioration of the protrusion.
Further, as shown in FIGS. 15 and 16 of the above-mentioned Patent Document 1, a process of forming a cam-shaped protrusion and a cylindrical portion into which a pin is inserted on both sides is formed at the tip of the link (rocker). Is not easy because it is formed of a metal plate that can withstand external pressure against bending.

  The present invention provides a new second spring that replaces the spring provided in the conventional slide hinge, or by providing a further spring, or is easy to press-mold, and is a durable second link that can withstand external pressure in the bending direction. By using, an object of the present invention is to provide a slide hinge that can apply a biasing force in a direction in which the door is pushed back in the final narrow-angle region that closes the door, and that can reduce manufacturing costs.

The slide hinge according to claim 1 is configured such that a cup attached to a door end of a furniture, a storage, a building, and the like and an attachment arm are connected by a first link and a second link, and the attachment arm is attached to a wall surface of the door opening. A slide hinge that can be attached to and detached from the mounting seat with a single touch.
A pin connecting the one end of the first link and the vicinity of the tip of the mounting arm supports a base of a spring having a substantially V shape in a side view, and the one end of the spring abuts the mounting arm. The other end of the spring is in contact with the first link, and the urging force in the direction of pushing back the door is applied to the mounting arm and the first link in the final narrow angle region for closing the door. There is a feature.

The biasing force of the spring built in the slide hinge acts in a direction in which both ends of the spring are separated when an external force is applied in a direction in which both ends of the spring are close to each other. The angle at which this urging force acts is the final narrow angle region that closes the door. For example, the door is pushed back until the door is completely closed from a state where the door is slightly opened at an angle of 20 ° to 35 °. Power is acting. For this reason, this urging force is applied even after the door has been closed. To maintain the closed state of the door, other latches, hooks that engage and release, and magnetic catches, etc. It is necessary to lock the door with the locking member. As described above, when the slide hinge of the present invention is used in combination with another locking member, the door can be opened slightly only by lightly pushing the closed door, and the subsequent operation of opening the door wide by hand becomes easy.
The spring also has a second action of acting in a direction to stabilize the angle of the first arm with respect to the mounting arm at a constant angle, and this second action is free from backlash when the slide hinge is opened and closed. Prevents the door from opening and closing smoothly.

  In the slide hinge according to claim 2, the pin connecting the first link and the vicinity of the tip of the mounting arm further supports a base portion of a second spring having a substantially V shape in a side view. The one end of the spring contacts the mounting arm, and the other end of the spring contacts the back plate surface of the first link or the second link.

  In this slide hinge, the above-described two actions are individually performed by two springs. The spring according to claim 1 acts in a direction in which the door is pushed back in the final narrow-angle region where the door is closed, but when the door is opened further, the spring biasing force does not act. Therefore, the second action described above is limited to a certain range. According to the second aspect of the present invention, another spring is provided in order to exert the second action in the entire region of the door opening / closing angle.

The slide hinge according to claim 3 is connected through a first link and a second link in which the inner side of the cup attached to the door end of furniture, a building or the like and the vicinity of the tip of the attachment arm are pin-supported, and the attachment A slide hinge having a structure in which an arm is detachably attached to a mounting seat attached to a wall surface of a doorway,
A pin connecting the one end of the first link and the vicinity of the tip of the mounting arm supports a base of a spring having a substantially V shape in a side view, and the one end of the spring abuts the mounting arm. The other end of the spring abuts the front end surface of the second link facing the mounting arm of the back plate surface, and the door is closed to the mounting arm and the second link in the final narrow angle region. It is comprised so that urging | biasing force may be added to the direction which pushes back.

In the slide hinge, one end of the spring is brought into contact with the mounting arm, and the other end of the spring is brought into contact with the back plate surface of the second arm, thereby exhibiting the above-described two actions.
This idea can be seen in the slide hinge described in Patent Document 1 described above. In the slide hinge described in Patent Document 1, a plastic protrusion is provided at the tip of the second arm (rocker), or The problem is solved by molding a tongue-shaped protrusion and a cylindrical portion holding a pin at the tip of the two arms (rocker).
In this slide hinge, a spring is provided at the tip of the back plate portion of the second arm in order to eliminate the trouble caused by the provision of the plastic projection and the difficulty of molding the tongue-shaped projection having a cam shape and the cylindrical portion side by side. The one end of the was brought into contact. Specifically, the side cross-sectional shape of the tip of the second arm was made U-shaped, a pin hole was provided on the opposing surface, and one end of the spring was brought into contact with the back plate surface. When the tip of the second arm has such a shape, it has a strong shape that does not bend even when a strong biasing force is applied by a spring, and can be easily formed by press working.

According to the slide hinge of the first aspect, in the last narrow angle region where the door is closed, the urging force is applied in the direction of pushing back the door. Open the door a little, and then you can easily open the door.
In particular, since the slide hinge of claim 1 can be manufactured simply by attaching a new spring in place of the spring built in the conventional slide hinge having two links, the parts of the conventional slide hinge can be used as they are. The manufacturing cost of the hinge can be reduced.

  In addition, as in the slide hinge of claim 2, the pin that supports the mounting arm of the slide hinge and the first link, the spring that smoothly opens and closes the slide hinge, and the last narrow angle that closes the door Even if the region is supported by a spring that exerts a biasing force in the direction in which the door is pushed back, the same effect as that of the first aspect can be obtained.

  Further, as in the slide hinge of claim 3, a pin that supports and connects the mounting arm and the first arm is supported by a base portion of a spring having a substantially V shape in a side view, and one end of the spring is supported. The above-described effects can be obtained even when the first portion is brought into contact with the inner surface of the back plate surface of the first arm and the other end portion of the spring is brought into contact with the back plate surface of the second arm. In particular, the end of the back plate surface of the second arm is brought into contact with one end of the spring so that the second arm can be molded easily and a strong second arm can be obtained. became.
