Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a furniture hinge, and more particularly to a hinge arm that can be attached and detached together with a door by a spring-operated locking mechanism provided on a mounting plate provided on the furniture body. This invention relates to a furniture hinge.

According to known technical aspects, the hinge arm is generally supported on the mounting plate by two screws. In this arrangement, one screw is attached to the internal thread of the mounting plate and projects through the elongated hole in the hinge arm, thus tightening the hinge arm to the mounting plate. The screw also serves to adjust the installation depth. A second screw, also known as a joint adjustment screw, is attached to the internal thread of the hinge arm and projects with its head into a recess drilled in the mounting plate or rests on the mounting plate. Such hinge arms have a U-shaped appearance.

It is also known to fix the hinge arm in such a way that the lateral flange of the hinge arm is provided with an inwardly projecting edge that can be inserted into a lateral groove of the mounting plate. Typically, the hinge arm is secured to the mounting plate by a clamp or spreader screw.

A hinge in which a spring catch mechanism, ie a catch member, is provided on the hinge arm or on the mounting plate is known from German Patent Application No. 30 26 796. Briefly describing the mechanism described therein, for installation, the hinge arm is pushed onto the mounting plate and the protrusion of the hinge arm fits into the side recess of the mounting plate. Additionally, the hinge arm is movable over a portion of the length of the mounting plate. The intermediate plate is fixed to the mounting plate with screws,
The intermediate plate has a notch into which a spring catch mechanism of the hinge arm engages when the hinge arm is pushed onto the mounting plate.

This type of hinge facilitates the attachment of the door to the furniture body.

When assembling such furniture, the mounting plate of the hinge is fixed to the furniture side wall or the intermediate wall of the furniture, while the hinge casing is inserted into a hole drilled on the corresponding inside of the furniture door. After the furniture main body is assembled, the door can be attached to the main body simply by attaching the hinge arm to the mounting plate, as described above. During this process, the door is first held;
And the hinge arm, which is then attached to the mounting plate, must be held in the same way. This work can be done if additional screws to be secured are not required.
It will be done easily.

However, reducing the travel distance of the door during installation poses considerable difficulties, especially in multi-hinged doors of the known type in which the hinge arms are inserted into the lateral guide means of the mounting plate. This is because, in the case of a tall door, the inclinations of the hinge arms with respect to the preset mounting plate do not all match, which tends to cause misalignment. Furthermore, although adjustment of the mounting depth of the hinge arm is possible with the above-mentioned type of hinge, this adjustment requires the hinge arm to be removed from the mounting plate, which is extremely unreasonable.

However, an object of the present invention is to completely eliminate the above-mentioned misalignment that tends to occur when attaching a hinge arm to a mounting plate, and to provide a spring locking mechanism that is extremely easy and reliable to attach to the mounting plate. The present invention relates to improvements in furniture hinges of the type secured by. Furthermore, apart from this problem, it is another object of the present invention to provide a furniture hinge in which the above-mentioned installation depth can be adjusted and the surface position between the side surface of the door and the side surface of the furniture body can be adjusted extremely easily without removing the mounting plate. be.

According to the invention, such a furniture hinge comprises:
at least one hole drilled in the mounting plate; and at least one hole that is attached to the hinge arm, has a notch cut on its outer periphery, and is fitted into the hole along a direction perpendicular to the mounting plane. one rod member, the rod member being attached to the mounting plate so as to be slidable in first and second directions parallel to the mounting plane and facing each other, and when the rod member is fitted into the hole; a catch member having at least one through hole drilled therethrough; and a catch member attached to the mounting plate and biased in the first direction to fit the through hole in the catch member into a notch cut in the rod member. and spring means for locking the bar member and therefore the hinge arm to the mounting plate, the spring means being embedded in and abutting the mounting plate. a torsion spring having a second leg latched to the catch member; and the catch member is configured to engage the catch member for disengaging the bar member from the hole and the through hole. This is achieved by providing a handle at the rear end for moving the notch in the second direction toward release from the notch against the elastic force of the spring means.

According to the configuration as described above, when installing the furniture hinge according to the present invention, even if several hinges are arranged along the height of the door, each hinge arm is simply set on the mounting plate, and then the hinge arm is installed. Just push it onto the mounting plate by hand and it will lock instantly there.

Moreover, in order to achieve the above-mentioned object, the present invention has the following features:
at least one hole drilled in the mounting plate; and at least one hole that is attached to the hinge arm, has a notch cut on its outer periphery, and is fitted into the hole along a direction perpendicular to the mounting plane. A rod member, extending parallel to the mounting plane on each side of said hole and biased toward each other, locks said rod member and thus the hinge arm to the mounting plate by engaging said notch. spring means embedded in the mounting plate; and a spring means embedded in the mounting plate; and the rod member is fixed by separating the pair of legs from each other and releasing the legs from the notch. and a spreader member rotatably embedded in the mounting plate for removing the furniture from the hole.

EMBODIMENT OF THE INVENTION Hereinafter, the furniture hinge according to the present invention will be explained in more detail along with the embodiments shown in the drawings.

In the embodiment according to FIGS. 1 and 2, the hinge arm 1 has a notch 12 cut into its outer periphery.
Mounting plate 2 providing a mounting plane for the entire hinge via two bar members 3a and 3b.
Supported by In another embodiment described below, these rod members are divided into two adjustment screws that respectively adjust the lateral displacement and installation depth of the door to be installed, each of which performs a different function. There is. Furthermore, the mounting plate is provided with a hole 17 into which a bar member is fitted along the vertical direction, and spring means for biasing a catch member 4 that directly locks or releases the bar member, which will be described in detail later. 10 are buried. Further, although the mounting plate itself is fixed to the inner wall of the furniture body using wood screws, it is obvious that it may be fixed by other methods.

Before entering into detailed explanations, the mounting manner of the furniture hinge according to the present invention will be briefly explained with reference to FIGS. 14 and 15.

The mounting plate 2 has an overall elongated shape as shown in FIG. 1, and its longitudinal axis is fixed horizontally to the inner edge of the side plate of the furniture body 27 along the depth direction. A hinge arm 1 having a similar elongated shape is also supported in the same direction. The hinge arm 1 has a rectangular cross section with two generally parallel side flanges, and two mutually parallel pins P, P pivotally connected between the side flanges.
Further, as shown in FIG. 14, each of the pins has a cup 30 embedded in the door 28 at its other end through separate parallel pins S, S, respectively.
Two bending link arms 29 pivotally supported via
is rotatably supported. These two bending link arms 29 and four pins P, P and S,
The link mechanism consisting of S allows the door 28 to operate in a unique manner, that is, when opening the door, the door is first pulled forward and then rotated.
Further, when closing the door, the door can be operated in the reverse order, and the door is finally closed in the state shown in FIG. 15. A more detailed explanation will be omitted, but the above explanation will be sufficient to simply understand the manner in which the hinge is attached to the door according to the present invention.

As seen in FIGS. 1 to 7, the mounting plate 2 has an elongated shape that extends over its surface, and extends in a first direction and a second direction that are colinear and opposite to each other. Slidable catch members 4 are mounted parallel to the mounting plane and have a substantially "C" cross-sectional shape, as seen in particular in FIG. longitudinal flanges 8a, bent parallel to each other, with mutually inwardly bent edges 8, 8 slidably engaging in two lateral grooves 9 respectively cut parallel to the mounting plane; 8a. Also,
This catch member is provided with through holes 11, 11 through which the rod members 3a, 3b are fitted into holes 17, 17 formed in the mounting plate 2, and the shape is similar to that of a key. It is a non-circular hole such as a keyhole, and has an inner diameter that allows the rod member to pass through it without excessive rubbing after the edge of the catch member is separated from the notch 12 of the rod member when the catch member is slid. must be prepared. In this sense, the through hole is preferably an oblong hole.
Furthermore, in order for the notch 12 to fit into the edge of the through hole in a good manner, in other words to obtain a larger engagement area, it is obvious that the shape of the notch 12 is preferably an annular groove. It is.

Further, the spring means 1 embedded in the mounting plate 2
In the embodiments shown in Figures 1, 3, 4, and 7, a so-called coiled torsion spring is used, and one leg is attached to the mounting plate. A first leg 10' abuts against the inner surface, and a second leg 10'' projects from the mounting plate and is engaged with the catch member 4.

As can be understood from the above structure, when fixing the hinge arm 1 to the mounting plate, the catch member 4 is moved in the second direction B, that is, inside the furniture body, against the elasticity of the spring means 10. Then, the rod members 3a, 3b attached to the arms are fitted into the corresponding holes 17, 17, and finally the catch member is moved in the first direction, which is the direction in which the spring means 10 is unloaded. By being biased in the direction, the edges of the through holes 11, 11 become the notches 12, 12 of the bar member.
When the hinge arm 1 is inserted into the furniture body 27, the hinge arm 1 is firmly locked to the furniture body 27. Of course, if the hinge arm is to be removed from the mounting plate 2, it is obvious that the above procedure can be reversed.

A handle 13 is disposed at a suitable position to facilitate sliding of the catch member 4 in the second direction against the elastic force of the spring means 10. In the illustrated case, the inner end of the catch member is simply bent upward, but considering that the elastic force of the spring means does not need to be set very large, this level of elasticity is sufficient. be.

However, the operation of locking the hinge arm 1 to the mounting plate 2 can be completed by simply pressing the hinge arm against the mounting plate without any manual effort by rounding the ends 3' of the rod members 3a and 3b. It is obvious to do so. Therefore, the installation of the furniture hinge according to the present invention to the furniture body can be completed with one touch, and the installation of the hinge arm is extremely easy compared to the above-mentioned known example, and removal from the installation plate 2 is also easy. It is only necessary to slide the catch member in the second direction B and then rotate the hinge arms one by one, and even if a large number of doors are attached to a tall door, installation and removal can be completed in a very short time, and this is a well-known method. This provides convenience not found in other examples.

In addition to such convenience, the furniture hinge according to the present invention is equipped with a mechanism that allows easy position adjustment after installation, and the specific configuration thereof will be explained below.

In FIG. 1, one of the two rod members 3a is provided with a threaded portion 15 that is screwed into the hinge arm 1 in order to adjust the separation distance of the hinge arm 1 from the mounting plate 2, and the other is 3b

It is rotatably mounted on the The cam means 1
In this embodiment, numeral 4 is formed by an eccentric ring constituted by a threaded shaft portion having a rotation axis eccentric to the axis of the rod member 3b. By rotating the right-hand bar member 3a with thread 15, the hinge arm 1 moves the door 28 laterally, and by rotating the left-hand bar member 3b with cam means 14, the hinge arm 1 moves the door 28 laterally. door 28
is moved in the depth direction, that is, in the front-back direction, making it possible to fine-tune the installation position of the door. This configuration is a feature not seen in the above-mentioned known examples,
It also constitutes a main component of the present invention.

In the embodiments shown in FIGS. 3 to 7,
The rod members 3a, 3b are integrally formed with an intermediate member 5 fixed to the hinge arm 1 by at least one tightening screw 6, and the threaded portion 15 of one rod member 3a is formed from the rod member. The rod member 3b is separated and screwed into the hinge arm and locked to the intermediate member to form the joint adjustment screw 7, and the upper portion of the other rod member 3b is also divided to form the tightening screw. . Such an intermediate member 5 is thus supported on the hinge arm 1 by means of a tightening screw 6 and a joint adjustment screw 7. Joint adjustment screw 7
is itself screwed to the hinge arm 1, similar to the right-hand bar member 3a of the embodiment in FIG. The joint adjustment screw 7 is also provided with an end flange 7' through an annular groove 7'', and a longitudinally extending slot 16 bored in the open end of the intermediate member 5 and the annular groove 7''. is engaged. The mounting plate 2, catch member 4 and spring means 10 are the same as those in the embodiment shown in FIG.

In such a configuration, when attaching the hinge arm 1 to the mounting plate 2, it is sufficient to simply press the hinge arm against the mounting plate as in the previous embodiment, and when releasing it, the catch member 4 is attached to the furniture. This is achieved by pulling it towards the back of the body.

In this embodiment, the hinge arm, i.e. door 2

In the above configuration, two of the spring means 20
The book legs 20', 20' extend toward the rear end of the hinge arm 1 and parallel to the mounting plate 2, forming a hairpin shape as a whole.

Further, the rotation axis of the spreader member 23 is aligned on a line connecting the centers between the two rod members 3a and 3b, and forms a "T" shape as shown in FIG. The action is carried out along the part shown horizontally in the figure, that is, the part 23a acting between both legs and the inner peripheral wall of the hole drilled in the mounting plate 2 in which the spreader member is embedded. and a portion 23b that protrudes perpendicularly to the operating portion that guides the rotation during rotation. In order to adjust the spreader member from the outside, an opening 1a is provided at a corresponding position in the hinge arm 1.

On the other hand, the spring means 20 is provided on the outer periphery of the mounting plate 2.
A horizontal groove 2a is bored therein to accommodate the spring means 20 and to ensure the locking action of the spring means 20, and the spreader member 23 can be rotated 90 degrees to allow the spring means legs to expand.
