Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a hinge mounted between a door opening frame and a door, with an improved opening adjustment device.

``Prior Art'' As one of the hinges used for furniture such as cabinets, a link mechanism consisting of multiple arms is formed by a mounting plate attached to the door opening frame of the furniture and a socket attached to the furniture door. There are hinges in which the hinges are relatively rotatably and relatively bendable, and hinges in which an opening adjustment device is built into the hinge have already been provided.

By the way, the hinge shown in Figure 1 was created before this application.
It was manufactured based on technology introduced from Europe, and is equipped with an opening adjustment device described below.

In the case of the hinge illustrated in FIG. 1, the rear ends of the mounting plate 1 and the slide arm 2 and both ends of the rear arm 3 are pivotally connected to each other, and the front end of the mounting plate 1 and the guide arm 5 are pivotally connected to each other.
The rear end portions are pivotally connected to each other, and the slide arm 2
A longitudinally intermediate portion of the guide arm 5 and a longitudinally intermediate portion of the guide arm 5 are pivotally connected to each other via a shaft pin 6, and a front end portion of the slide arm 2 and a rear end portion of the socket 4 are pivotally connected to each other. The front end of the arm 5 and the rear end of the support arm 7 are pivotally connected to each other, and the front end of the support arm 7 and the front end of the socket 4 are also pivotally connected to each other.

When attaching the hinge illustrated in FIG. 1 across the door opening frame 8 and the door 10, the mounting plate 9 is screwed to the inner surface of the door opening frame 8, and the socket 4 is inserted into the recess provided on the inner surface of the door 10. After being fitted into 10a and fastened with screws, the mounting plate 1 of the mounting plate 9 is covered and fastened with screws.

Thus, the door 10 can open and close the opening of the door opening frame 8 via the hinge, and exhibits a large opening angle when the opening is opened.

The opening adjustment device equipped on the hinge shown in FIG.
The tip of the adjusting screw 11 is connected to the slide arm 2 and the socket 4.
They are designed to abut against each other's shaft pins 12 (or a portion of the sockets 4).

In the case of such an opening adjustment device, the adjustment screw 11 is rotated clockwise or counterclockwise to adjust the position where the tip of the adjustment screw 11 hits the shaft pin 12, thereby adjusting the position of the door 10 relative to the door opening frame 8. The opening angle can be adjusted.

``Problems to be Solved by the Invention'' When trying to widen the adjustment range of the opening in the above-mentioned opening adjustment device, it is obvious that a long adjustment screw 11 is required.
Such a long adjustment screw 11 protrudes largely from the plane (surface) of the support arm 7, depending on the adjustment state.

This impairs the appearance of the hinge, and there is also a risk that people or other objects may get caught in it.

Furthermore, in the case of the adjustment screw 11, it is difficult to turn it with a fingertip, and a tool such as a screwdriver is required, resulting in poor operability.

In view of these technical issues, the present invention aims to improve safety by preventing parts from protruding to the outside, operability that allows adjustment with your fingertips, stability of operation of important parts, and improved appearance. The purpose of this invention is to provide a hinge opening adjustment device that can be used.

"Means for Solving the Problem" In order to achieve the intended purpose, the opening adjustment device according to the present invention includes a mounting plate that is attached to the door opening frame, a socket that is attached to the door,
In addition, the mounting plate and the slide arm are equipped with a slide arm, a guide arm, a support arm, and a rear arm as parts for a link mechanism to connect the mounting plate and the socket in a relatively rotatable and relatively flexible manner. The rear ends of the mounting plate and both ends of the rear arm are pivotally connected to each other, the front end of the mounting plate and the rear end of the guide arm are pivotally connected to each other, and the longitudinal intermediate part of the slide arm and the rear end of the guide arm are pivotally connected to each other. The longitudinal intermediate portions are pivotally connected to each other, the front end of the slide arm and the rear end of the socket are pivotally connected to each other, and the front end of the guide arm and the rear end of the support arm are pivotally connected to each other. In a hinge in which the front end of the arm and the rear end of the socket are pivotally connected to each other, the support arm has a screw hole extending in a direction intersecting the plane of the arm, and a screw hole above the screw hole extending along the plane of the arm. A shaft bearing portion having a substantially U-shaped side surface with a cavity is provided, and a rotary ring is fitted into the cavity of the shaft bearing portion, and the rotary ring passes through the upper wall of the shaft bearing portion and rotates. The ring is rotatably supported via a hollow shaft that spans the axial center of the ring, and an adjustment screw is fitted into the hollow shaft to prevent rotation, and the end of the adjustment screw is screwed into the screw hole. The hinge is characterized in that it collides with the socket side when the hinge is in an open state.

``Operation'' In the case of the opening adjustment device according to the present invention, the mounting plate attached to the door opening frame and the socket attached to the door are connected to the slide arm,
The guide arm, support arm, and rear arm are connected by a link mechanism that allows them to rotate and bend relatively freely, so by attaching these mounting plates and sockets across the door opening frame and the door, the door can be opened. It can be opened and closed relative to the door opening frame.

In the above, the end of the adjustment screw provided on the support arm collides with the socket side when the hinge is in the open state.

The adjusting screw is moved in a predetermined axial direction by rotating it clockwise or counterclockwise through a rotating ring.

Therefore, by operating the rotary ring with your fingertips, you can adjust the position where the end of the adjustment screw hits the socket side, and by such adjustment, the opening angle of the door relative to the door opening frame can be adjusted.

``Example'' An example of a hinge incorporating an opening adjustment device according to the present invention will be described with reference to FIGS. 2 to 7.

Note that, hereinafter, portions, parts, and members common to those described with reference to FIG. 1 will be described using the same reference numerals as those in FIG. 1.

The hinge illustrated in FIGS. 2 and 3 is the door opening frame 8.

The rear end portions are pivotally connected to each other via a shaft pin 17.

The above-mentioned hinge has a stopper 18 for keeping the door closed, as illustrated in FIGS. 2 and 3.
is equipped with.

This stopper 18 has an engaging recess 18b on the rear side.
A catch 18a formed at the front end of the mounting plate 1 with Coil-wound spring 18d locked to (no code)
and a roller 18c rotatably attached to the other end of a spring 18d, and the roller 18c is pressed against the catch 18a via the elastic force of the spring 18d.

The opening degree adjusting device of the present invention has various aspects described with reference to FIGS. 2 to 7.

As a common configuration in FIGS. 2 to 7, the support arm 7 has a screw hole 25 in a direction intersecting the plane of the arm, and a side surface having a hole 20 above the screw hole 25 along the plane of the arm. A U-shaped shaft bearing portion 19 is provided, and the rotating ring 21 is fitted into a cavity 20 of the shaft bearing portion 19.

As a common configuration in FIGS. 4 to 6, the hollow shaft 22 passes through a shaft hole 28 formed in the upper wall 19a of the shaft bearing part 19, and is fitted and fixed to the shaft center of the rotating ring 21. The adjusting screw 24 rotatably supports the rotary ring 21, and has a square head 24a and a rod-shaped threaded portion 24b.
It is fitted into the square hole 23 of No. 2, and its threaded portion 24b is screwed into the threaded hole 25 of the support arm 7.

In this case, the hollow shaft 22 and the adjustment screw 24 can be moved relative to each other in the axial direction because their square holes 23 and square heads 24a engage with each other and prevent each other from rotating. Relative rotation in the circumferential direction is not possible.

As a common configuration in FIGS. 2 to 5 and 7, the shaft bearing part 19 has a rear end part of the support arm 7, a member 26 separate from the support arm 7, which is attached to the shaft pin 16 as a main body. They are integrally assembled at a fitting part 27.

In this case, there is an air space 20 between the rear end of the support arm 7 and the member 26.

The shaft bearing part 19 in FIG. 6 is formed integrally with the rear end part of the support arm 7, that is, it is constructed by cutting out the rear end part of the support arm 7, which is formed thickly. The notch is empty (20).

The rotating ring 21 and the hollow shaft 22 described above are the fifth
In the case of Fig. 6, each of the parts is made up of independent parts, which are combined and fixed together.

On the other hand, in the case of FIG. 7, the rotating ring 21
and a hollow shaft 22 are integrally formed.

In the above, it is desirable that the lower end of the hollow shaft 22 be flush with the bottom surface of the rotating ring 21, and that its upper end be flush with the upper surface of the shaft bearing part 19 or protrude slightly from this.

The adjusting screw 24 assembled to the support arm 7 in the above is arranged so that its end collides with the socket 4 side (the peripheral edge 4a of the socket 4 or the shaft pin 12) in the door open state shown in FIG. 3, which will be described later. become.

As shown in FIGS. 2 and 3, the hinge equipped with the opening adjustment device according to the present invention has a mounting plate 9 screwed to the inner surface of the door opening frame 8, and a socket 4 provided on the inner surface of the door 10. After being fitted into the recess 10a and secured with screws, the mounting plate 1 is placed over the mounting plate 9 and secured with screws.

Thus, when the door opening frame 8 and the door 10 are connected via the hinge so as to be openable and closable, the door 10 can be closed as shown in FIG. 2 and opened as shown in FIG. 3.

In the hinge that performs the function of opening and closing the door,
When the door 10 is fully opened, the end of the adjusting screw 24 collides with the peripheral edge 4a of the socket 4 or the shaft pin 12, etc., so that further opening of the door is restricted.

The opening degree of the door 10 determined in this way is adjusted by operating the adjustment screw 24 via the rotary ring 21.

That is, when the rotating ring 21 is rotated clockwise or counterclockwise with a fingertip, the adjusting screw 24, which rotates together with the rotating ring 21 via the hollow shaft 22, is engaged with the screw hole 25. , it moves in the axial direction within the hollow shaft 22 and is displaced below or above the support arm 7, so that the amount of protrusion of the threaded portion 24b that protrudes below the support arm 7 changes.

In this adjustment, as the amount of protrusion of the threaded portion 24b increases, the end of the adjustment screw 24 collides with the socket 4 at a smaller opening angle; conversely, the amount of protrusion of the threaded portion 24b increases. As the size becomes smaller, the end of the adjusting screw 24 collides with the socket 4 at a larger opening angle.

Therefore, when the amount of protrusion of the threaded portion 24b is increased, the degree of opening of the door 10 is decreased, and when the amount of protrusion of the threaded portion 24b is decreased, the degree of opening of the door 10 is increased.

``Effect of the invention'' The opening adjustment device according to the invention has a hinge support arm having a predetermined configuration, and a predetermined adjustment means mainly including a screw hole, a bearing part, a rotating ring, a hollow shaft, an adjustment screw, etc. The end of the adjustment screw collides with the socket side when the hinge is open, so the hinge can be adjusted to the desired opening by operating the adjustment screw. useful and informative.

One of these is that the adjustment screw can be moved in the axial direction by simply rotating the rotary ring with a fingertip without the use of a tool, making it easy to adjust the opening and improve operability.

Another advantage is that the adjustment screw is not only screwed into the screw hole of the support arm but also held by the hollow shaft, so that the operation of the adjustment screw is stable when adjusting the opening.

Furthermore, the other thing is that it is only necessary to adjust the amount of movement of the adjustment screw within the range of the length of the hollow shaft. It must be safe to prevent people or other objects from getting caught, it can have a good appearance, and there is no risk of losing the adjustment screw.
