Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hinge used for attaching a door to a box body or other door attachment member so as to be openable and closable.

(Prior art) In a conventional hinge, a first hinge body attached to a door and a second hinge body attached to a mounting member of the door are rotatable by multiple arms or the like. It is known that the device is connected to the device and is configured to be able to open and close freely.

As such a hinge, one shown in FIG. 1θ is known.

That is, both the first and second hinge bodies 8 are formed in a symmetrical shape. At the front end of a', on the front side in the state of use, there is an arm b having a number of thousand-sided approximately dogleg shape.
, one end of b' is connected to a pin c located at an opposing position in the vertical direction,
c', the two arms b and b' are pivoted so as to be freely rotatable, and the other ends of the arms b and b' extend toward the other hinge body a and a', and the above-mentioned arms b and b' are stacked vertically, both arms b
, b' are pivotally connected to each other at their bent portions by means of pins d at the crossed portions so that both can freely rotate.

Further, the other ends of the two arms b, b' are inside the other hinge bodies a, a' to which the respective arms b, b' are not pivotally connected by the pins c, c', a guide groove e provided in the front-rear direction when the hinge is in use;
e' through the bins f and f' so as to be slidable in the front and rear directions by rotation of the door.

Next, a hinge shown in FIG. 11 has already been proposed, in which a mole is located on the front end side of two symmetrically formed first and second hinge bodies a and a'. At the opposing parts of the arms b and b', which are long symmetrically curved arms in the upper and lower arrangement with the hinge in use, the base ends of the arms b and b' are placed at the bins c and c',
The arms b, b are pivotably attached to each other so as to be rotatable, and are located near the inner part of the corner hinge bodies a, a'.
'More central than the pivot point! lAg4 has a short link g
, g' are pivoted so as to be rotatable by a pin 1-°, and the arms b and b' are rotatable by a pin d at a portion where they cross each other approximately at the center thereof. The tips of the inner arms b, b' and the other ends of the links g, g', which are pivoted to the other hinge bodies a, a', are rotated by the pins h, h'. They are each pivoted so that they can move freely.

Therefore, in these hinges, one hinge body δ is li
tInsert the other hinge body 6 into the recess in the mounting member membrane.
゛After fitting each into the recess provided on the hanging side of the ``゛゛,
By fixing with screws, ILK can be attached to its mounting member.
It will be pivoted so that it can be opened and closed freely to the opening.

(Problem to be Solved by the Invention) In other words, in the one in FIG. 10 (former), in order to increase the amount of Jjlk taken out when changing from the open state to the open state, the arms b, b' and other The end is the hinge body δ,
It is configured to slide relative to In contrast, the front and rear dimensions of the hinge bodies a and a' become larger, whereas the one in Fig. 11 (
In the latter case, by eliminating the sliding mechanism of the arms b and b' and interposing a link 8.8° between the end of each arm b and b' and the hinge body a and a', Hinge body a
, a' in the front-back direction can be made small, so that the amount of jlk that can be taken out when opening can be increased.

However, even if the hinge is in the above direction, if the door k is attached externally to the door mounting member j, the amount of extension of the door that can be opened to the widening angle can be secured, but the first
As illustrated in Figure 2, if @k is attached internally to door mounting member j, it will become impossible to open due to the structure of the hinges, making it impossible to attach the door internally, and the range of use will be limited accordingly. In the former case, the arm would have to be long, its bending angle would have to be small, and the sliding amount at the other end would have to be considerably large. On the other hand, in the latter case, the arm must be long and its bending angle must be small, and the link must also be long. However, with this configuration, the dimensions of the hinge body in both the front and rear and left and right directions are extremely large. Due to the large size, the recess for embedding the hinge body is thick and deep, making it impossible to install it on a normal door or door mounting member, and when the door is closed, the hinge body As the distance between them increases, the distance between the first layer and the door mounting member also becomes very wide, making it impossible to actually use them.

The present invention has been made in view of the above-mentioned problems of the conventional hinge, and the arms are bent asymmetrically, one end is long and the other is short, and the other end of each arm is By interposing links of the same length or different lengths between the hinge body and the hinge body, the door can be opened and closed freely by rotation, and the amount of the door that can be lifted out when opened can be increased. The purpose is to allow the door to be attached internally to the door mounting member, and also to allow the door to be opened at a wide angle.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a first hinge body attached to a door and a second hinge body attached to a mounting member of the door. , in a hinge which is connected via a plurality of arms or the like so that the door can be opened and closed by rotation, located on the front end side of both the first and second hinge bodies,
At approximately opposite positions, the proximal ends of long arms of different lengths, which are symmetrical and curved at different angles in the vertical arrangement when the hinge is in use, are rotatable. At the same time, one end of the link is attached near the inner part of the front hinge main body and closer to the center than the pivoting part of the arm so that it can rotate or slide in the front and back direction. The two arms are pivotally connected to each other so that the crossed portions at their substantially central portions are rotatable, and the tips of the two arms and the other end of each link attached to the other hinge body are connected to each other. It is an object of the present invention to provide a hinge characterized in that the hinges and the hinges are pivotally connected to each other so as to be rotatable.

(Function) When the first hinge body attached to the door and the second hinge body attached to the door mounting member are in the closed state, the front ends of each are in an opposing state, and in this state In this case, the arm whose base end is pivotally attached to the first hinge body has its tip inserted into the second hinge body, and the link whose base end is attached to the hinge body is connected to the arm. Due to the pivoting, it is located inside the second hinge main body and held in a state substantially parallel to the front end surface.

On the other hand, the arm whose base end is pivotally attached to the second hinge body also has its tip inserted into the first hinge body, and the link attached to the first hinge body is connected to the first hinge body. It is located inside the main body and is held in an inclined state with respect to its front end surface.

When the door is opened from the above-mentioned closed state, each arm is rotated toward the other hinge body around the pivot point with the hinge body to which each arm is pivoted, and at this time, each link is pivoted. If it is attached to the hinge body by a fastener, it will be rotated toward the front end of the hinge body around the pivot point.

Further, when the link is attached to the hinge body by a sliding mechanism, the link is slid toward the front end side of the hinge body.

Therefore, as a result of this, the door is opened and the amount taken out is also increased.

That is, when the door is opened and closed, each link is attached to the hinge body at its lower end by a long arm with a large bending angle and a short arm with a small bending angle. If there is a hinge, the distal end of the arm can be rotated by approximately 9θ° around the pivot point to the outside of the hinge body, thereby increasing the amount of lifting out.

In addition, if one end of the link is attached to the hinge body by a slide mechanism, the one end slides forward and the tip of the arm can be moved to the outside of the hinge body, which also reduces the amount of carryout. Therefore, it is possible to internally attach the cap to the door mounting member, and the door can be opened at a wide angle.
