Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hinge capable of selectively regulating the opening angle between vanes.

In the case of conventional hinges, the opening angle of the vanes is free, or even if it is regulated, each of the adjacent bearing parts of the hinge has a part of the stopper installed in advance that comes into contact with each other. Generally, a desired uniform opening angle was obtained by stopping the opening angle.

However, with hinges that are not regulated in opening angle, when opening a fixed door, etc., the hinges may open beyond the necessary angle and collide with other objects such as adjacent pillars, causing damage. It was not uncommon for the hinges to open at a predetermined opening angle by blocking some of the opposing stoppers from each other. It is impossible to change the selection of the angle, and furthermore, no matter which hinge is used, the existence of the pivot support itself exposed to the outside when used fixedly creates a sense of discomfort from the external appearance. However, there were some drawbacks such as:

This invention was created to eliminate the drawback of tilting in hinges, and in a hinge in which a fixed blade plate and a rotating blade plate are rotatably supported via a support shaft, it is possible to solve the problem of tilting the hinge. A rotary vane plate consisting of a support shaft with a locking protrusion on the end face, an appropriate number of protrusions on the outer peripheral side of the shaft head, and a plurality of fitting grooves carved into its inner peripheral wall. It is integrally inserted into the shaft hole of the fixed wing plate and the shaft hole of the fixed wing plate, which has an engagement protrusion erected at the bottom of the blade.
Therefore, the gist of the present invention is to selectively restrict the opening angle of the rotary vane.

An embodiment of the present invention will be described below in detail with reference to the drawings.

The rotary vane plate 1 that firmly supports the door body etc. to be opened and closed is approximately U.
It consists of a letter-shaped fixing plate part 2 and a pair of support arms 3 of the same shape and size extending perpendicularly at each open end of the fixing plate part 2.

On the outer open surface of the fixing plate part 2 in the direction in which the support arm part 3 extends, a blocking plate 5 is attached slightly above the support arm part 3 to be able to block a fixture plate 4, which will be described later. There is.

A shaft hole 6 is bored in the outer end of each support arm 3 so that the respective opening surfaces face each other, and a wall surface of the outer end of the shaft hole 6 has a hole parallel to the drilling direction. A plurality of fitting grooves 7 are carved.

Further, an appropriate number of fixing screw holes 8 are drilled on the side of the fixing plate 2 of the support arm 3 so as to intersect with the shaft hole 6, and a plurality of fixing screw holes 9 are drilled in the fixing plate 2, respectively. It is set up.

The fixed wing plate 4 to be fixed to a support W such as a pillar or wall surface is
It is formed by using a plate material having a width that allows it to be fitted between the support arms 3 of the rotary vane plate 1.

This fixed vane plate 4 has a shaft hole 11 to be supported by a support shaft 10.
It consists of a support arm 12 with They extend parallel to each other in opposite directions across the arm portion 14.

When the fixed vane plate 4 is fitted to the rotary vane plate 1, the rotary vane plate 1
A shaft hole 1 is provided at an appropriate position of the support arm 12 facing the shaft hole 6 provided in the shaft hole 6 so as to communicate with the shaft hole 6.
1 are respectively provided, and an engagement protrusion 15 having substantially the same shape as a door formed when the opening surface of the shaft hole 11 is divided upward is provided at the deep bottom of both of the shaft holes 11. has been done.

The shape of this engagement protrusion 15 is such that the maximum opening angle of the rotary vane plate 1 is regulated in relation to the locking protrusion 16 of the support shaft 10, which will be described later. The specific shape does not matter as long as the desired maximum opening angle can be obtained.

In addition, the vertical positions of both of these engaging projections 15 at the deep bottom of the shaft hole 11 are such that, as shown in FIG.
It is also possible to provide one engagement protrusion 15 as shown in FIG.
It is also possible to provide the other engaging protrusion 15 on the extension line of the position adjacent to , and the present invention is not limited to these examples.

A supporting arm portion 12 and a connecting arm portion 14 are continuous in an abbreviated shape.
The support arm 12 is formed to have the same length as the support arm 3 depending on the thickness of the body to be fixed, and the length of the connecting arm 14 is the same as the length of the support to be fixed. It may be formed as appropriate depending on the thickness of W.

The fixed arm portion 13, which is continuous with the connecting arm portion 14 in an abbreviated shape, may have an appropriate length depending on the relationship with the supporting body W to be fixedly supported. A fixing screw hole 17 is bored.

, a pair of support shafts 10 formed to rotatably support the rotary vane plate 1 and the fixed vane plate 4 each have their respective shaft heads 18,
For example, as shown in FIG. 4, a hexagonal shape or a ninth
It is formed in a groove shape as shown in the figure.

Note that the shape of the outer circumferential side of the shaft head 18 is not limited to these, but may have a protruding angle that allows the fitting and locking with the fitting groove 7 to be performed while shifting the fitting position of both. You are free.

Further, the bottom end surface of the support shaft 10 is provided with a locking projection 16 that is to be locked with an engaging projection 15 that is erected at the bottom of the shaft hole 11 of the fixed blade plate 4 to be supported.

In this case, if the locking protrusion 16 is formed as a fan-shaped one with a center angle of 90 degrees, like the locking protrusion 15 in the illustrated example,
It is possible to restrict the opening angle of a fan-shape or the like to a maximum opening angle of 180 degrees.

In short, from 360 degrees, the engagement protrusion 15 and the locking mark 1
The sum of the central angles with 6 is subtracted to give the maximum opening angle obtained.

On the other hand, the support shaft 10 that pivotally supports the rotary blade plate 1 and the fixed blade plate 4 is pressed into contact with a fixing screw 19 screwed into the fixing screw hole 8 in order to prevent it from coming off.

In this case, the support shaft 10 to be pressed by the fixing screw 19
By providing a slightly cut recess 20 on the outer circumferential surface as shown in FIG. 4, the support shaft 10 can be more effectively prevented from coming off.

In addition, if a polygonal recess is provided in the axial direction of the top of the shaft 10, or if an acid threaded portion 21 is threaded as shown in the illustration, the support shaft 10 can be removed and reinstalled as necessary. Fitting and insertion can be carried out extremely easily by fitting a screwdriver or screwing together a male screw.

Further, the fixing screw 19 may also be provided with a minus or plus groove on its top, but as shown in the figure, for example, a hexagonal recess 22 may be provided, and a screwdriver with a hexagonal cross section may be inserted into this. By fitting the fixing screw 19, there is less risk of losing it when the fixing screw 19 is attached or removed.

Although not shown in the drawings, if a cover made of synthetic resin or the like is attached to the shaft head of the support shaft 10 itself, the fixing screw 1
It is also possible to effectively prevent the support shaft 10 from coming off without using the support shaft 9.

This invention is constructed as described above, and in its use, first, the rotary vane plate 1 and the fixed vane plate 4 are connected to the shaft hole 11 provided with the support arm 124 in the fixed vane plate 4. A blocking plate in which the shaft hole 6 provided in the support arm 3 of the plate 1 communicates with the connecting arm 14 of the fixed vane plate 4 attached to the fixed plate part 2 of the rotary vane plate 1. 5, and the supporting shafts 10 are fitted into the communicating shaft holes 6 and 11, respectively.

In this case, if both the engagement protrusion 15 and the locking protrusion 16 are formed into fan shapes with a center angle of 90 degrees as shown in the figure, the opening angle can be appropriately regulated to a maximum opening angle of 180 degrees. I can do it.

For example, if the shaft head 18 of the support shaft 10 is hexagonal and 12 fitting grooves 7 are formed in the shaft hole 6 of the rotary vane plate 1, 180 A wide variety of opening angles can be obtained in 30 degree increments, from 30 degrees to 30 degrees.
If 24 grooves are carved in both the groove 8 and the fitting groove 7, an even greater variety of opening angles can be obtained from 180 degrees to 15 degrees in 15 degree increments as shown in FIG. It will be done.

If each of the engaging protrusion 15 and the locking protrusion 16 is formed into a fan shape with a center angle of 45 degrees, the maximum opening angle can be up to 270 degrees.

That is, the opening angle can be selectively regulated as required.

The spindle 10, which has been fitted and inserted in such a manner that the desired opening angle is obtained, is fixed by pressure contact with the set screw 19 screwed into the set screw hole 8, so that it cannot be pulled out unnecessarily. There's nothing to do.

When using the hinge thus assembled, the second
As shown in the figure, the fixed arm part 13 and the connecting arm part 14 are fixed by screwing the fixed wing plate 4 itself with a screw through the fixing screw hole 17 so that the side surfaces of the fixed arm part 13 and the connecting arm part 14 are in contact with the support W, respectively. .

When fixing the door body etc. to the rotary vane plate 1, screw the door body etc. so that it comes into contact with the respective sides of the supporting arm part 3 and the fixing plate part 2, which are formed in an abbreviated shape. Just wear it.

In this case, it is also possible to use a door body or the like on the fixed vane plate 4 as shown in FIG. 3, and to use the rotary vane plate 1 by fixing it to the support W as appropriate.

In this way, the parts corresponding to the bearings in conventional hinges are integrally formed in the rotating vane plate 1 and the fixed vane plate 4 as the shaft hole 6 and the shaft hole 11, respectively, so that the door body, etc. Not only is the load evenly distributed over the entire rotary blade plate 1 and fixed blade plate 4 when the blades are fixed, but also protrusions such as bearings are not exposed to the outside, resulting in excellent robustness and improved aesthetics. It looks nice too.

As explained above, according to the present invention, the opening angle of the hinge can be selected and regulated in small increments as necessary, so it is effective to damage the body by colliding with an adjacent object such as a pillar. Not only can the opening angle be changed as necessary, it can fully meet the various demands of users.Furthermore, it has excellent robustness, and the installation can be done for aesthetic purposes later. It exhibits extremely excellent effects, such as being preferable to
