Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window equipped with a shock absorber, and particularly to a window equipped with a shock absorber equipped with a stop mechanism that stops the window at a predetermined position (open position).

The window applied to the present invention is a window that has a rotating shaft and rotates about the rotating shaft, that is, a vertical or horizontal rotating window, a window that folds inwards or outwards, a single-hinged window, or a double-hung window.

In recent years, as buildings have become taller, the windows themselves have become larger and heavier, and those on higher floors in particular are forced to experience considerable wind pressure when the windows are opened or left open.

This wind pressure acts on the window to increase the opening/closing speed in the opening or closing direction depending on the direction of the wind. For example, when wind pressure acts in the window opening direction, the window increases the opening speed and reaches the stop at the fully open position. If the window hits the window with an impact and acts in the direction of closing the window, the window will hit the window frame with an impact, which not only causes damage to the window glass, but also prevents people from passing under the building due to the damage to the window glass. This may result in an unexpected accident for passersby.

In order to prevent such accidents, windows are equipped with shock absorbers that act to resist window movement and reduce the opening/closing speed only when the opening/closing speed of the window increases due to wind pressure or other factors. This was proposed in Utility Application No. 53-72744.

This invention relates to the improvement of Utility Application No. 53-72744,
A shock absorber equipped with a stopping mechanism for stopping the window at a predetermined opening position (opening angle) is attached to the window, thereby eliminating the need for a separate stopping device.

More specifically, a rod cover is fixed to one end of the hydraulic cylinder and a rod cover is fixed to the other end to form a hydraulic chamber within the hydraulic cylinder, and the hydraulic chamber is filled with liquid. A piston having a nationally designated flow hole is slidably disposed in a piston rod whose respective ends protrude from the head cover and rod cover.
A ring groove is formed in the piston rod on the outer circumferential surface of the head cover side from the position where the piston is fixed, and an engagement hole is formed in the head cover at a position perpendicularly facing the piston rod. A fixing pin containing a steel ball elastically supported by a spring is fixed in the engagement hole so that the steel ball is positioned on the rond side to constitute a stopping mechanism, and the shock absorber constructed in this manner The hydraulic cylinder of the device is rotatably attached to a mounting bracket fixed to the window frame, and the piston rod protruding from the rod cover side is rotatably attached to a mounting bracket fixed to the window frame. It provides a built-in window.

Furthermore, a cylindrical recess 64 is formed in the fixing pin 6 from the end of the threaded part 61 in the axial direction thereof, and the fixing pin 6 passes through the center of the head cover 4 through the opening of the cylindrical recess 64. It is screwed and fixed toward the hole 41 side.

A reduced diameter portion 11 having a reduced diameter is formed at the tip of the piston rod 100 on the rod cover 9 side, and a twisted portion 12 is formed on the outer peripheral surface of the reduced diameter portion 11.

Further, a ring groove 13 having a concave spherical cross section is formed on the outer circumferential surface of the piston rod 10 on the side of the helad cover 4 .

The steel balls 1 and 7 contained in the fixed pins 5 and 6 fixed to the head cover 4 and pressed by the springs 8 and 8 move the piston rod 10 toward the rod cover 9 side in the ring groove 13. That is, it fits into the window at a predetermined opening position (opening angle), prevents the movement of the piston rod 12, and locks the piston rod 10 at that position.

The ring groove 13 is closed when the window is closed.

In this way, the ring groove 13 formed in the piston rod 10 and the steel balls 7, 7 contained in the fixing pins 5, 6 fixed to the helad cover 4 and pressed by the springs 8, 8 are fitted together. A stopping mechanism is configured.

In this stopping mechanism, when the ring groove 13 and the steel ball 7 are fitted together, when a wind pressure of a predetermined level or higher is applied, the steel ball 7 is forced into the ring groove against the elastic force of the spring 8 that elastically supports the steel ball 7. 1
Since the fitting with 3 can be disengaged, there is no need for large wind pressure when the window is open, and no additional force is required to disengage the fitting when the window is closed, which will cause problems when closing the window. There isn't.

Although the example diagram shows an example in which a single ring groove 13 is formed on the piston rod 10, it is also possible to form two or three ring grooves depending on the window opening angle and select the opening angle. You can also.

0 is inserted into the piston rod 10, and springs S, S are inserted into the piston rod 10.
Fixed by

An annular recess 102 is formed on the outer peripheral surface of the piston 100, and a seal ring R is installed in the annular recess 102.

The broken piston 100 has a communication hole 10 through its plate surface.
3 is formed.

The hydraulic chamber A of the hydraulic cylinder 3 is divided into hydraulic chambers A1 and A2 by the piston 100, and the hydraulic chamber A1 is divided into hydraulic chambers A1 and A2.
, A2 communicate with each other through a communication hole 103 formed in the piston 100.

A hydraulic cylinder 3 and a hydraulic chamber A formed within the hydraulic cylinder 3.
A shock absorber is constituted by a liquid (oil) 0 filled in the head cover 4, a rod cover 9, a piston rod 10, and a piston 100 having a flow hole 103.

In this shock absorber, a hydraulic chamber A formed in a hydraulic cylinder 3 is divided into hydraulic chambers A1 and A2 by a piston 100 disposed within the hydraulic chamber, and a piston rod to which the piston 100 is fixed. 10 is arranged so as to penetrate through the hydraulic chamber A and protrude from the head cover 4 and the rod cover 9 at both ends, so that the volume reduction of the hydraulic chamber A1 (or hydraulic chamber A2) caused by the movement of the piston 100 is prevented. The amount is equal to the increase in the volume of the hydraulic chamber A2 (or the hydraulic chamber A□).In other words, there is no change in the volume of the hydraulic chamber A due to the movement of the piston 100, so the piston 100
The communication hole 1 formed in the piston 100 by the movement of
A buffering effect is exerted by the flow resistance of liquid 0 flowing through 03.

Therefore, in normal window opening/closing operations, the displacement between the hydraulic cylinder 3 and the piston 100 occurs at a relatively low speed.
When the liquid 0 in the hydraulic pressure chamber A flows through the flow hole 103 of the piston 100, the flow resistance is small, so when opening and closing the window normally, a large force is required to open and close it, and the opening and closing is not smooth. It will not cause any inconvenience.

Furthermore, when a large force is applied to the window due to wind pressure or the like while the window is opening or closing or when the window is open, that is, when the opening/closing speed increases, the relative speed between the hydraulic cylinder 3 and the piston 100 increases, and as a result, the liquid applied to the piston surface increases. 0 pressure increases and acts to prevent the movement of the piston 100, and this acts as a resistance force to prevent mutual displacement of the hydraulic cylinder 3 and piston 100, preventing movement of the window in the opening/closing direction. To prevent the window from impactfully abutting against a building member.

Reference numeral 200 is a mounting bracket fixed to the window sill 2.

The mounting bracket 200 has a through hole 201 that engages with the shaft portion 54 of the fixing pin 5 fixed to the head cover 4.

The fixing pin 5 is connected to the through hole 20 of the mounting bracket 200.
After engaging the shaft portion 54 of the fixing pin with 1, the through hole 201
(Place a washer on the more protruding pin thread part 55)
It can be rotated within the through hole 201 by screwing and attaching N.

In other words, the hydraulic cylinder 3 to which the fixing pin 5 is fixed is configured to be rotatable with respect to the mounting bracket 200.

Reference numeral 300 denotes a support fitting that is screwed and fixed to the hydraulic cylinder 3 and tightened with a nut N via a spring washer W to the threaded end portion 12 of the piston rod 10 protruding from the rod 9 side. .

A support fitting 300 fixed to the tip of the piston rod 10
is superimposed on the mounting bracket 400 fixed to the window frame 1,
At the overlapping portion, the bolt 500 is rotatably attached to the shaft portion 5011 of the bolt 500 by means of a bolt 500 and a bolt H.

700 is a protection tube screwed and fixed to the other end of the head cover 4.

Reference numeral 800 denotes a stopper bolt fixed to the tip of the piston rod 10 on the side of the head cover 4, and the stopper bolt 800 comes into contact with the head cover 4 when the window is fully opened and prevents further opening.

Next, the operation and effects of the shock absorbing window equipped with the stop mechanism constructed as described above will be described.

When the window is opened from the window closed position by a normal window opening operation, the piston rod 10 is moved to the hydraulic cylinder 3 as the window is opened.
The piston 100 pulled out from the piston rod 10 and fixed to the piston rod 10 also moves within the hydraulic pressure chamber A of the hydraulic cylinder 3 as the piston rod 10 moves.

At this time, the piston rod 10 is rotatably supported by a support fitting 300 fixed to its tip with respect to a mounting fitting 400 fixed to the window frame 1, and the hydraulic cylinder 3 is fixed to the window frame 2. Since it is rotatably supported on the mounting bracket 200, the hydraulic cylinder 3 and piston rod 1 are rotated by the rotation of the window.
Mutual displacement with the piston 100, which is fixed at zero, occurs smoothly.

Then, when the piston rod 10 moves, that is, when it falls to a predetermined window opening position (opening angle), the steel ball 7 provided in the head cover 4 and pressed by the springs 8, 8 is inserted into the ring groove 13 formed in the piston rod 10. , 7 are fitted, and movement of the piston rod 10 is prevented.

In other words, the window is stopped in its open position.

As mentioned above, during the normal window opening operation, the mutual displacement between the hydraulic cylinder 3 and the piston 100 occurs at a relatively low speed, so that the liquid (oil) flowing through the circulation hole 101 formed in the piston 100 The flow resistance at 0 is also small, and the window can be opened without causing any inconvenience such as the need for a large force or the opening not being smooth.

In this state, that is, when a large wind pressure is applied with the window stopped at a predetermined open position by the stop mechanism, the ring 13 formed on the piston rod 10 constituting the stop mechanism and the steel balls 7, 7 will not fit together. However, the relative speed between the hydraulic cylinder 3 and the piston 100 increases, which increases the pressure of the liquid 0 on the piston surface, causing the piston 100 to move. The movement of the window is prevented.

As a result, the window does not rotate in the opening or closing direction under impact, and the window is prevented from impactfully contacting the stop part or the window frame when the window is fully opened, thereby preventing damage to the glass shoji 1. be able to.

As described above, the present invention enables the usual opening and closing of windows to be performed without causing inconveniences such as requiring a large force or not opening/closing smoothly. By installing a shock absorber that resists the movement of the window only when the opening/closing speed becomes large, preventing the window from increasing in opening/closing speed and thereby preventing the window from impactfully contacting building members, This can prevent damage and, by extension, accidents caused by damage.

Furthermore, since the shock absorber is equipped with a stopping mechanism that stops the window at a predetermined opening position (opening angle), there is no need to provide a separate stopping mechanism, which is preferable in terms of the aesthetics of the room.

In addition, although the vertical axis revolving window is shown in the embodiment, the same effect can be achieved with other horizontal axis revolving windows, windows that tilt inward or outward, and single- or double-hung windows.
