Description

[Detailed description of the invention] [Field of industrial application] The present invention is a hinge for a folding door used as a room partition or a folding door. The target is a hinge that can be temporarily fixed during bending.

[Conventional technology]

The hinge of the present invention is applied to a folding door as shown in, for example, Japanese Utility Model Publication No. 10384/1984, and takes the form of connecting a pair of door panels so that they can be bent around one axis.

This type of hinge is known, for example, from Japanese Utility Model Publication No. 56-35504. Furthermore, door hinges equipped with a stopper to the same effect were developed in 1982.
This method is known from Japanese Patent Publication No. 126478 and Japanese Patent Publication No. 55-49677.

In such a roller hanging type folding door, for example, when folding the door panel with a small sandwiching angle between the door panels, if the operating position is too low or if the door panel is operated suddenly, the door panel may move around the center of rotation of the runner. The door may swing and tilt, causing the door panel to get caught between the upper and lower rails.

To avoid such a situation,
As shown in the above publication, it is preferable to temporarily fix a pair of door panels with hinges at a sandwiching angle of around 45 degrees so that the folding door can be opened and closed in that state. However, this hinge takes the form of bending the door panel around two central bending axes.

[The problem that the idea attempts to solve]

The hinge of Utility Model Publication No. 56-35504 has a steel alloy cam piece fixed to one hinge plate,
A click stop mechanism consists of a ball held by the other hinge plate and a spring that presses the ball against the cam piece.By providing a recess in a predetermined position where the ball falls and engages, the pair of doors can be opened. Panels can be temporarily fixed at an angle of around 45 degrees.

The problem is that since the cam pieces and the balls are adjacent to each other on the left and right along the panel wall, most of the cam pieces protrude from the end faces of the pair of door panels when the door panels are completely folded. With such hinges, clothing may be caught on a cam piece that protrudes from the end face of the panel. Furthermore, there is a risk of injury if the user accidentally hits the cam piece.

Therefore, the object of the present invention is to provide a hinge with excellent safety without the risk of clothing getting caught or injury, especially a hinge for a folding door that can temporarily fix a pair of door panels in the middle of bending.

[Means to solve the problem]

The hinge of the present invention is applied to a folding door in which a plurality of door panels 1 are bendably connected by a hinge 2, and each door panel 1 is guided by upper and lower guide rails 4 and 6.

The hinge 2 includes a hinge plate 10L in which a pin boss 13 is integrally formed, and a pin bracket 14.
a hinge plate 10R integrally formed with
A hinge pin 11 that is inserted through a pin boss 13 and a pin bracket 14 to connect a pair of hinge plates 10R and 10L, and both hinge plates 10.
It consists of a click stop mechanism 12 that holds the R and 10L fully open and fully closed, and at an acute angle position of 45 degrees or more.

The click stop mechanism 12 includes a hinge pin 11
A pair of fixed rings 15 and a movable ring 16 are fitted onto the pin 11 and are adjacent to each other between a pair of pin bosses 13 along the axis of the pin 11, and are arranged between the movable ring 16 and one pin boss 13, Movable ring 16
and a compression coil type spring 17 that presses the fixing ring 15 against the fixing ring 15.

The fixing ring 15 is attached to one hinge plate 10L.
It has an arm 18 that circumscribes the surface wall of the arm 18, and a pin 19 provided on the arm 18 is fitted and engaged with the hinge plate 10L,
It is integrated with this hinge plate 10L so as to be able to swing together.

The movable ring 16 has a pair of parallel engaging arms 20 protruding from the circumferential surface of a cylindrical wall with a bottom, and the engaging arms 20 are attached to a bulging wall 21 formed on the face wall of the corresponding hinge plate 10R. It is inserted into the hinge plate 10R and integrated with the hinge plate 10R so as to be slidable toward the side away from the fixing ring 15.

A spring 17 is housed in a cylindrical hole 16a of a movable ring 16 that fits over one pin boss 13 in the assembled state.

On the adjacent surfaces of the fixed ring 15 and the movable ring 16,
Fully open and fully closed positions and both hinge plates 10
At an intermediate position where the angle between R and 10L is an acute angle of 45 degrees or more, a protrusion 24 and grooves 25 to 27 that engage with each other to maintain the posture are provided.

[Effect]

Since the click stop mechanism 12 is composed of a fixed ring 15 and a movable ring 16 adjacent to each other along the axial center of the hinge pin 11, and a spring 17 accommodated in the cylindrical hole 16a of the movable ring 16, the door panel 1
As the opening and closing states of the members 15 and 1 change, each member 15,1
Neither 6 nor 17 protrudes from the outer surface of the door panel 1.

The pin 19 provided on the arm 18 is connected to the hinge plate 10.
L, the fixed ring 15 is integrated with the hinge plate 10L, and the pair of engaging arms 20 are inserted into and engaged with the bulging wall 21, and the movable ring 16
Since it is integrated with the hinge plate 10R, a fastening member for integrating both rings 15 and 16 can be omitted, and the hinge 2 can be assembled with less effort.

[Effect of idea]

In the present invention, the click stop mechanism 12 is configured by the fixed ring 15 and the movable ring 16 that are vertically adjacent to each other, and the spring 17 provided between the movable ring 16 and the pin boss 13, and the movable ring 16 slides along the hinge pin 11. By being displaced, the click stop mechanism 12 is switched between an engaged state and a non-engaged state, so that each member 15, 16, 1
7 can be prevented from protruding to the outer surface of the door panel 1. This can prevent clothing from getting caught on the hinge 2 or injury from hitting the hinge 2, and can improve the safety of the hinge 2 in folding doors that are often applied to living rooms.

The fixed ring 15 and the movable ring 16 can be integrated by simply fitting and engaging the hinge plates 10L and 10R, respectively, and by finally incorporating the hinge pin 11, the fixed ring 15 and the movable ring can be integrated. 16 can be maintained in the assembled state, especially each ring 15, 16.
There is no need to use a fastening member or the like to fix the hinge plates 10R and 10L to each hinge plate 10R, 10L, which has the advantage of simplifying the structure of the hinge 2 and reducing manufacturing costs.

[First Embodiment] Figures 1 to 6 show a first embodiment in which the present invention is applied to a folding door for a partition.

In Figures 2 and 3, the folding door is constructed by connecting four door panels 1 with hinges 2 so that they can bend freely, and a runner 3 with a roller structure provided at the top of each door panel 1 is fixed to the ceiling wall or lintel. It is guided and supported in a hanging manner by a guide rail 4, and a steady pin 5 provided at the bottom of each door panel 1 is guided and supported by a lower guide rail 6 fixed to the floor surface.

The runner 3 and the door panel 1 are connected by a hanging pin 7, and by aligning the vertical centers of the hanging pin 7 and the steady pin 5, the door panel 1 is placed horizontally with respect to both guide rails 4 and 6. Allows swinging. The steady pin 5 is urged downward by a spring 8, and the flange 5a at the lower end thereof is received and supported by the opening edge of the rail groove 6a of the guide rail 6.

In FIG. 1, the hinge 2 includes a pair of left and right hinge plates 10R, 10L, both plates 10R,
10L, and a click stop mechanism 12 that holds both hinge plates 10R, 10L in fully open, fully closed, and intermediate positions.

As shown in FIG. 5, the left and right hinge plates 10
At the connection points of R and 10L, a pair of pin bosses 13 and a pair of pin brackets 14 are formed by bending the plate surfaces, and the pin bosses 13 are sandwiched vertically between the pin brackets 14 and assembled, and both members 13, 14 are assembled. Both plates 10R and 10L are connected to each other so as to be able to swing relative to each other by a hinge pin 11 which is inserted through the two plates at the same time.

The click stop mechanism 12 includes a pair of upper and lower fixed rings 15 and a movable ring 16 that are fitted onto the hinge pin 11 between a pair of pin bosses 13, and a spring that biases the movable ring 16 against the fixed ring 15. 17.

An arm 18 is extended from one side of the outer surface of the fixing ring 15, this arm 18 is brought into contact with the outer surface of the left hinge plate 10L, and a pin 19 protruding from the contact surface of the arm 18 is fitted into the hinge plate 10L. By fitting the fixing ring 15 to the hinge plate 10
Fixed so that it can swing along with L.

Similarly, a pair of parallel engaging arms 20 are extended from one side of the outer surface of the movable ring 16, and the engaging arms 20 are fitted onto the bulging wall 21 of the right hinge plate 10R, so that the movable ring 16 is hinged. It is connected to the plate 10R so that it can swing together.

The bulging wall 21 is set to have a width larger than the width of the engaging arm 20, and is configured to slide the engaging arm 20 so that the entire movable ring 16 can move in the axial direction against the biasing force of the spring 17. I am giving you a moving guide.

The spring 17 is made of a compression coil spring, and is interposed between the innermost end of the cylindrical hole 16a of the movable ring 16 and the pin boss 13 facing thereto. As shown in FIG. 1, when the fixed ring 15 and the movable ring 16 are assembled, the cylindrical hole 16a slightly fits into the pin boss 13, and therefore the inner spring 1
7 is not visible from the outside of the hinge.

Both hinge plates 10R, 10R, 10R, 10R, 10R,
It has an engaging means 23 for maintaining the posture of 10L.
This engagement means 23 includes a rib-shaped protrusion 24 that protrudes across the end face of the fixed ring 15 side in the radial direction, and first and second rib-like protrusions formed on the end face of the movable ring 16 corresponding to the protrusion 24. 2, each third groove 25, 2
It consists of 6 and 27.

As shown in FIG. 4, when the adjacent door panels 1 are in the fully open position where they are flat on the same plane,
The protrusion 24 fits into the first groove 25 as shown in FIG. 6a. When the door panel 1 is bent from this state,
The movable ring 16 is pushed down against the spring 17 and the protrusion 24 is removed from the groove 25. When the door panel 1 is subsequently bent, the protrusion 24 fits into the second groove 26 as shown in FIG. 6b. When the door panel 1 is further bent to the fully open state, the protrusion 24 fits into the third groove 27 as shown in FIG. 6c.

The second groove 26 is formed at the adjacent door panel 1.
The third groove 27 is preferably shown so that the angle between the two grooves is within an acute angle of 45 degrees or more.
It is formed at a position 45 to 50 degrees away from the formation position in the circumferential direction. In other words, when the angle between the door panels 1 is 45 to 50 degrees, the protrusion 24 is inserted into the second groove 2.
Set it to fit into 6.

If the included angle is less than 45 degrees, for example 30~
When setting the angle to 44 degrees, the door panel 1 may swing around the runner 3 before the protrusion 24 fits into the second groove 26, and the steady pin 5 may come off the guide rail 6, making it unstable. Lacks sex. Furthermore, if the angle is small, the runners 3 will approach each other, making it almost impossible to prevent the steady pin 5 from coming off. Further, when the included angle is larger than 90 degrees, the runners 3 are sufficiently far apart from each other, so the steady pin 5 will not come off the guide rail 6. Furthermore, when the included angle becomes 90 degrees or less, out of the component force of the operating force applied to the door panel 1, the component force perpendicular to the panel surface of the door panel 1 (i.e., the component force that is perpendicular to the panel surface of the door panel 1)
The force pushing along the panel surface of the door panel 1 is larger than the force acting along the panel surface of the door panel 1 (the force that bends the adjacent door panel 1), and there is a risk that the door panel 1 will swing around the runner 3. .

For the above reasons, the position where the protrusion 24 fits into the second groove 26 is set at an angle where the sandwiching angle between adjacent door panels 1 is within an acute angle range of 45 degrees or more.
