[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotating window brake.

[0002]

2. Description of the Related Art A vertical or horizontal rotating window, an inward or outward window, a one-sided or double-sided window or a protruding window is
In recent years, buildings have become larger and heavier with the rise of buildings.

[0003]

Problems to be Solved by the Invention By the way, this enlarged window causes various problems when it is opened and closed. For example, when a strong wind pressure is applied by a gust when opening and closing a window, the wind pressure acts on the window to increase the opening / closing speed in the opening direction or the closing direction depending on the wind direction. Increases the opening speed and impacts against the stop at the fully open position, and when acting in the closing direction, the window impacts against the window frame, thereby only causing damage to the window glass. Instead, shards of window glass can cause unexpected accidents to passers-by underneath the building. In particular, windows located on higher floors are subject to considerable wind pressure, which is particularly problematic. Also, since the sealing seal provided at the periphery of the window frame acts as a resistance when the window is opened, a relatively large force is required when the window is opened. However, when the window is opened, the window suddenly disappears, so that a person who tries to open the window with a large force may fall.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a method for opening and closing a window when a large force such as wind pressure acts on the window when the window is opened and closed to increase the opening and closing speed of the window. An object of the present invention is to provide a revolving window brake capable of resisting movement and preventing an increase in opening / closing speed.

SUMMARY OF THE INVENTION According to the present invention, there is provided a rack configured to be attached to one of a window frame and a window frame of a rotating window, and a pinion meshed with the rack. A rotating body connected to the pinion, a stator arranged with a gap between the rotating body and a window frame or a window frame of the rotating window, and a rotating body; And a prohibition mechanism for freely prohibiting the rotation of the rotating window, and achieved by a brake for a rotating window in which a viscous fluid is disposed in a gap so as to generate a viscous shearing resistance force by relative rotation of the stator with respect to the rotating body. Is done.

Further, according to the present invention, the object is to attach one end to one of a window frame and a window frame of a rotary window so as to be rotatable about a rotary axis parallel to the rotary axis of the rotary window. A rack, the other end of which is a free end, a pinion that meshes with the rack, and is rotatable around a rotation axis parallel to the rotation axis of the rotation window; and The pinion case is rotatable about the rotation axis parallel to the rotation axis of the rotation window, and the rotation body connected to the pinion, and the other of the window frame and the window frame of the rotation window. And a stator arranged with a gap between the rotor and the rotor, wherein the stator is rotated relative to the rotor so as to generate a viscous shear resistance by relative rotation of the stator. With a viscous fluid,
The pinion case is also achieved by a rotary window brake adapted to guide the movement of the rack when opening and closing the rotary window while ensuring the mutual engagement between the rack and the pinion.

The rotating window referred to in the present invention includes all the windows rotating about one axis such as the above-mentioned vertical or horizontal rotating window, inward or outward folding window, single or double swing window, or protruding window. It contains.

The rack according to the present invention may be mounted on either the window frame or the window frame of the rotating window, and the stator may be mounted on either the window frame or the window frame of the rotating window. In one preferred embodiment, the rack is mounted on a window frame and the stator is mounted on a window frame.

According to one aspect of the present invention, the stator comprises a container for storing a viscous fluid, and a rotating body is disposed in the container with a gap to the container. The rotating body and the stator are arranged in the container.

[0010] Like the former, the latter one of the brakes for both rotating windows of the present invention may further comprise a prohibition mechanism for prohibiting the rotation of the rotating body freely.

[0011]

The rotary window brake of the present invention is used, for example, by attaching a rack to a window frame of a rotary window and a stator to a window frame of the rotary window. During the opening and closing operations of the rotating window, the rack is linearly moved together with the rotating window, so that the pinion meshing with the rack is rotated. As a result, the rotating body connected to the pinion is also rotated, so that relative rotation occurs between the stator and the rotating body, and the viscous fluid existing in the gap between the stator and the rotating body is subjected to viscous shear resistance. Force will be created.
This viscous shear resistance is generally expressed by the viscosity coefficient of a viscous fluid,
The areas of the two surfaces that viscous fluids move relative to each other in contact with each other, are proportional to the relative speed of the relative motion, and are inversely proportional to the distance between the two surfaces, so if the relative speed increases, in other words, the opening of the rotating window, When the closing speed increases, the viscous shear resistance increases, and when the relative speed decreases, in other words, when the rotating window opens and when the closing speed decreases, the viscous shear resistance decreases. If the opening and closing speeds of the window are to be increased, the viscous shear resistance is increased, and rapid rotation of the rotating window is prevented.

Hereinafter, the present invention will be described in more detail with reference to specific examples shown in the drawings. This and the other ideas will become clearer. The present invention is not limited to these specific examples.

[0013]

1 to 4, a vertical axis rotating window 1 is attached to a window frame 5 such that a window frame 3 into which a window glass 2 is fitted rotates in the direction A about the vertical axis 4. Is formed.

A brake 6 for a rotating window applied to the rotating window 1
Are a rack 7, a pinion 8 meshed with the rack 7, a rotating body 9 connected to the pinion 8, a container 10 for rotatably storing the rotating body 9, and a viscous fluid 11 stored in the container 10. Is provided.

The rack 7 having the teeth 12 has one end 13
The bolt 14 and the nut 15 are connected to a mounting bracket 16 so as to be rotatable about a rotation axis parallel to the vertical axis 4, and the mounting bracket 16 is mounted to the window frame 3 via a screw 17. The rack 7 is disposed so as to penetrate the pinion case 18, and a free end 19 is formed with a protrusion 20 for preventing the rack 7 from falling off. The pinion case 18 accommodates the pinion 8 and is provided rotatably about a rotation axis parallel to the vertical axis 4 of the rotation window 1.

The pinion 8, which is disposed in the pinion case 18 and has the teeth 21 meshing with the teeth 12, is connected to the vertical shaft 4 of the rotating window 1.
The rotation member 9 is rotatable about a rotation axis parallel to the rotation shaft 9 and is fixed to a shaft portion 22 of the rotation member 9 protruding into the pinion case 18 and connected to the rotation member 9. The rack 7 is guided by the side walls 23 of the pinion case 18 to move in the directions B and C and to ensure that the teeth 12 mesh with the teeth 21.

In this embodiment, the prohibition mechanism for freely prohibiting the rotation of the rotating body 9 is provided with a pinion 24 that is disposed in the pinion case 18 and meshes with the pinion 8.
One end 26 of the shaft 25 protrudes outside through an arc-shaped long hole 27 formed in the pinion case 18, and the other end 28 has an arc-shaped groove 2 formed in the pinion case 18.
9. On the back surface of the lid 30 of the pinion case 18, the pinion 24 is rotated by rotating the pinion 8 in the direction D.
An engagement piece 31 that prevents the unintended movement in the same direction is attached, and the engagement piece 31 that engages with the shaft 25 and holds the pinion 24 at the position shown in FIG. Is formed.

The rotating body 9 connected to the pinion 8 by the shaft 22 is connected to the container 10 via the steel balls 32 for holding the rotation center and a plurality of steel balls 33 arranged around the steel balls 32. E
The seal ring 3 is rotatably arranged in the direction and is disposed in the container 10. A seal ring 3 is provided between the lid 36 of the container 10 attached to the container body 34 by the retaining ring 35 and the rotating body 9.
7 are arranged, and the container 10 is
The viscous fluid 11 accommodated therein is prevented from leaking out of the container 10. The steel balls 32 are arranged in spherical grooves 39 and 40 formed in the rotating body 9 and the container 10 at the rotation center 38 of the rotating body 9, and the steel balls 33 are arranged in annular grooves 41 formed in the rotating body 9. As a result, the rotating body 9 can rotate relatively in the D and E directions with respect to the container 10 at the rotation center 38 with respect to the container 10, and a certain gap is formed between the rotating body 9 and the container 10. The container 10 is attached to the window frame 5 via the screw 42, and thus, in this example, the container 10 is a stator arranged with a gap from the rotating body 9. In addition, the shaft portion 22 protruding from the pinion case 18
, A retaining ring 43 is fitted so that the pinion case 18 is not pulled out of the shaft portion 22.

In the rotary window 1 provided with the rotary window brake 6 provided between the window frame 3 and the window frame 5 as described above, the window is opened and closed via a handle 50. Is released, the rack 7 is guided by the side wall 23 along with the rotation of the window frame 3 about the vertical axis 4 in the direction A, moved in the direction B, and rotated about the vertical axis 4. . Rack 7
This movement and rotation of the pinion 8 and the pinion case 18
Are respectively rotated in the E direction, and the rotation of the pinion 8 causes the rotating body 9 to rotate.
Is also rotated in the direction E in the container 10 about the center 38. When the rotary window 1 is opened to the maximum as shown by the solid line in FIG. 5, the rotary window 1 is prevented from being rotated further by a stopper mechanism (not shown). Conversely, when the rotation window 1 is closed, the pinion 8 and the pinion case 18 are respectively rotated in the direction D with the movement of the rack 7 in the direction C, and the rotation of the pinion 8 causes the rotating body 9 to rotate around the center 38 as well. 5, and finally the rotating window 1 is completely closed as shown by the dashed line in FIG.

Incidentally, the rotating window brake 6 is provided with the container 10
In the gap between the container 10 and the rotating body 9, the viscous fluid 11
Is arranged to cause the viscous fluid to generate viscous shear resistance by the relative rotation of the container 10 with respect to the rotating body 9, so that the viscous shear resistance is reduced to the speed of the relative rotation as described above. Since the rotation window 1 is rotated by a gust while rotating the rotation window 1 and the rotation speed of the rotation window 9 is increased, the rotation speed of the rotation member 9 is increased. Since the viscous shear resistance generated in the viscous fluid 11 with the container 10 increases, the increase in the rotation speed of the rotating window 1 is suppressed. Therefore, it is possible to avoid dangerous situations such as a collision of the window frame 3 with the window frame 5 or a stopper mechanism (not shown), breakage of the window glass 2, and the like.

In a desired open state, the engagement between the one end 26 of the shaft 25 projecting from the lid 30 and the engagement piece 31 is released against the elastic force of the shaft 25, and the one end 26 is moved along the elongated hole 27 into the D position. When the pinion 24 is moved so as to mesh with the rack 7, the rotation direction of the pinion 24 by direct transmission from the rack 7 and the rotation direction of the pinion 24 by transmission from the rack 7 via the pinion 8 are opposite to each other. Therefore, the rack 7 cannot move in any of the directions B and C, and the rotating window 1 can be held in a desired open state. To release the holding, one end 26 is inserted into the elongated hole 27.
Move in the direction E along the pinion 24 and the pinion 8
And the engagement with the rack 7 may be released.

In the specific example, the container 10 is directly mounted on the window frame 5 to constitute a stator. However, as shown in FIG. 6, for example, the rotating body 9 is inserted into the container 10 through steel balls 32 and 33. The disk 61 is accommodated by facing the disk 61 with a gap therebetween, and a mounting portion 62 connected to the disk 61 and arranged outside the container 10 is mounted on the window frame 5, and the disk 61 and the mounting portion 62 constitute a stator. You may. That is, according to the present invention, the brake 63 for the rotating window in which the container 10 is floated from the rotating body 9 and the stator may be used.

[0023]

As described above, the rotating window brake according to the present invention generates a viscous shearing resistance force in the viscous fluid by relative rotation of the stator with respect to the rotating body. Even if the opening and closing speeds of the rotating window are accelerated due to being raised, the viscous shearing resistance increases correspondingly and the rapid rotating operation of the rotating window is suppressed. Dangerous situations such as crashes and breakage of window glass can be avoided. Further, even if the window is opened with a relatively large force against the resistance of the hermetic seal, the rotation speed of the window does not suddenly increase, and there is no possibility that the operator falls.
