Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a concealed hinge for furniture, etc., which is pivotally connected by a plurality of links, and is particularly attached to the end face of the main body frame.

[Prior Art] Various types of multi-link hinges of this type have been provided in the past, but generally, as shown in Japanese Utility Model Publication No. 56-38134, a frame-type mounting member is fixed to the inside of the side plate of the main body. A cup-shaped mounting member was fixed to the inside of the door.

However, depending on the type of furniture or fittings, it may be necessary to attach them to the top and bottom frames of the main body. For example, in kitchen furniture such as sinks and cooking tables, multiple doors may be installed horizontally in the opening, but in this case, there is no side panel of the main body, and even if there is a side panel, it is configured as a mere partition. Sometimes.

One of the applicants, in view of the actual circumstances of the deception,
-20758 and No. 58-20759 are provided. The above hinge does not fix the frame through a washer, but the frame-type mounting member is fixed to the width of the top and bottom sides of the main body frame, and is erected in front of this fixing part to pivot the link plate. It consists of a supporting arm. Further, the cup-shaped attachment member is configured to be able to accommodate the arm portion of the frame-type attachment member.

[Problems to be Solved by the Invention] According to the above-mentioned hinge, since the arm portion of the frame projects horizontally forward, it cannot be used unless the door is completely covered with at least the end surface. However, in some cases, for example, when a curtain board is provided in front of the end surface of the top and bottom board, it may not be possible to completely cover the door due to the correlation between the end surface of the top and bottom board and the door.

A deceptive hinge is disclosed in Japanese Utility Model Publication No. 58-5827. However, since this hinge has a structure in which the front end of the frame is provided with a widened portion in the width direction, the respective width portions of the top plate and the base plate must face each other with their inner widths. To do this, it was necessary to prepare two different pairs of hinges, one for the top plate and one for the bottom plate. In reality, since a plurality of hinges must be manufactured and assembled, the cost is high and it is difficult to use.

The present invention has been further developed in view of the above-mentioned circumstances, and by extending the mounting surface area from the fixed surface area of the washer into a flat plate shape, one hinge can be attached to the top and bottom frame wood end surfaces. Its purpose is to make it available for use.

[Means for Solving the Problems] The features of the hinge according to the present invention for solving the above problems are that the washer has a substantially rectangular flat plate shape as a whole;
It has a fixed surface area fixed to the top and bottom ends of the main body frame, and a mounting surface area that integrally extends from this fixed surface area to the inside of the ends surface to which the frame can be attached, and this mounting surface area has the above-mentioned a notch for receiving a positioning protrusion protruding from the lower surface of the seat surface of the frame with a gap in the left and right direction; and a mounting screw member that is inserted into a long hole in the left and right direction in the middle of the seat surface of the frame to fix the frame. This is due to the fact that it is provided.

[Function] The cup-shaped mounting member is embedded into the mounting hole provided on the back side of the door, and the fixed surface area of the washer is fixed at a predetermined position on the top and bottom sides of the main body frame.

At the fixed position, the mounting surface area is extended inward from the butt end surface and is in an overhanging state. Therefore, if you position the frame by locking the positioning protrusion in the notch in the mounting surface area, and after making left and right adjustments as necessary, fix it with the mounting screw member.
The frame will be installed so as to protrude inward from the wood end surface.

[Embodiment] The drawings show an embodiment of the hinge according to the present invention, and FIG. 1 is a perspective view of the hinge in an attached state, and FIG. 2 is an enlarged sectional view of the hinge in a closed state.

The hinge 1 is made up of a frame type mounting member 2 attached to the top plate end surface a of the main body frame and a cup type attachment member 3 attached to the door b, which are pivotally connected by a plurality of link plates 4. is composed of a washer 5 fixed to the wood end surface a of the top plate and a frame 6 attached to the washer 5.

To be more specific, the washer 5 has a fixing surface area 7 formed approximately in width of the butt end surface a, and this fixing surface area 7
The mounting surface area 8 is integrally extended into a flat plate shape in the width direction, and is generally rectangular and flat plate shaped as a whole. The mounting surface area 8 is preferably configured to have approximately the same width as the frame 6, and includes a rectangular notch 9, a female screw hole 10, a pair of protrusions 11, and a protrusion 1.
2 are formed respectively. The notch 9 has a gap in the left-right direction as shown in the figure. or,
A hole 13 for a set screw 14 is provided in the fixing surface area 7 .

On the other hand, the frame 6 includes a flat seat surface 15 and a pair of arm portions 1 erected from the front side of the seat surface.
6 and 16, and an overhanging portion 17 extending horizontally slightly upward from between these. Above seat surface 15
has an elongated hole 18 in the middle, and a split groove 19 is formed at the rear end of the upper overhang 17 corresponding to this elongated hole 18. A mounting screw member 20 is provided.
In addition, a pair of positioning protrusions 2 are provided on the front side of the lower surface of the seat surface 15.
1 and 21 are protruded, and locking claws 22 and 22 are provided on the rear side.
is formed. 23 is a locking groove at the rear end of the seat surface.

Furthermore, the cup-shaped mounting member 3 is formed into a long cup in the left and right so as to be able to receive the arm portion 16 of the frame-type mounting member 2 and the mounting screw member 20, and the other end of the link plates 4, 4 is formed at the end thereof. is pivoted. Note that 24 is a flange of the cup-shaped mounting member 3, 25 and 26 are screw holes, and a set screw 27 is a packing material that is attached to the end of the door.

According to the above configuration, the cup-shaped mounting member 3 is embedded in the oval-shaped embedded hole c at a predetermined location of the door b, and the flange portion 24
Fix it with a set screw 26 through the screw hole 25. On the other hand, the fixing surface area 7 of the washer 5 is fixed to the end surface a of the top plate of the main body frame with a set screw 14 through a set screw hole 13. In the above-mentioned fixed state, the mounting surface area 8 protrudes from the end surface a of the top plate toward the inside of the main body frame, and is in an overhanging state with no support on the lower surface.

After that, the seat surface 15 of the frame 6 is brought close to and engaged with the washer 5. That is, if the positioning protrusion 21 of the frame 6 is engaged with the notch of the washer 5 and the locking groove 23 is engaged with the protrusion 12 at the same time, and after adjusting the position in the left and right direction, the mounting screw member 20 is screwed into the female threaded hole 10. The locking claw 22 engages with the protrusion 11 and is fixed.
Although not shown in the drawings, it is similarly attached to the end surface of the base plate with the attachment surface area opposite to that described above.

In the embodiment described above, the width of the mounting surface area 8 of the washer 5 is shown to be the same width as the frame 6, but it is also within the scope of the present invention to shift the width up or down depending on the door covering margin.

[Effects of the invention] As explained above, the invention provides the following effects.

When fixing a hinge that is pivotally connected with multiple links to the top and bottom butt ends of the main body frame, the mounting area where the frame can be attached extends from the washer fixed to the butt ends toward the inside of the butt ends for easy installation. In addition, the notch and the mounting screw member made it possible to perform left-right adjustment between the frame and the elongated hole.

Since the mounting surface area is extended, the frame can be mounted lower by positioning the winding end of the link plate in the notch.

The hinge body consisting of the frame and the cup-shaped mounting member can be mounted on the inside of the top and bottom ends without forming a pair, and the hinge body can be provided at low cost simply by forming the upper and lower washers as a pair.

Since the washer has a substantially flat plate shape from the fixing surface area and the mounting surface area, and the mounting surface area is provided with a notch and a mounting member, the washer can have an extremely simple structure and can be easily molded.
