Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a balance holding device for a rotating window with a stay damper when the window is closed.

(Prior Art) Conventionally, a rotating window that automatically opens has a pair of left and right vertical edges of the sash and a vertical frame of the window opening (vertical direction) or a horizontal edge of the sash and a horizontal frame of the window opening (horizontal plane). Although the window opening / closing device having the stay damper has been provided on the market, the one having the stay damper arranged on a horizontal surface is also characterized in that the window is not twisted.

However, it is practically impossible to install a pair of left and right stay dampers on the horizontal plane of the horizontal frame of the window opening in a small width window with a short width, so it becomes unavoidable that it becomes single and a torsion moment is generated in the window. Wind and rain may get in through the gap between the sash and the window, or it may change the room temperature and hinder the cooling and heating effect.

(Problems to be solved by the invention) In the case of a small width window having a relatively short width, the stay damper is single, and when the mounting angle is inclined with respect to the window frame as a means for preventing accidental opening of the window, During the closing of the window and in the window, the rod advancement force of the stay damper also plays the role of the window closing force, but on the other hand, a twisting moment is generated in the window, which causes adverse effects such as wind and rain penetration through the gap, room temperature change, etc. Simple means have become an issue for the industry.

(Purpose of the Invention) When a single stay damper is installed on a narrow window at an angle, a simple structure is used to prevent the harmful effects of the torsional moment. It is intended to be provided to.

(Means for Solving the Problem) In this balance maintaining device at the time of window closing, one end of the stay damper is pivotally attached to a support stand projecting from a lateral frame of the window opening, and the other end is attached to a lateral edge on the sash side. Immediately before closing the window, a roller is pivotally attached to one side of a slider slidably attached to a protruding stand, and a roller pivotally attached to the other side of the slider is fixed on another guide member fixed to the horizontal frame of the window opening. It is characterized in that the sliding contact is made.

(Operation) When the window that is closed is pushed out by hand, the pedestal protruding from the lateral edge on the sash side is integrated with the window, so it starts to move outside,
At the same time, the roller pivotally attached to the end of the slider attached to the frame passes over the top while sliding on the inclined surface of the guide member fixed to the horizontal frame of the window opening, and slides on the arc surface on the opposite side. The window reaches the full open point after it is moved down and separated, in which case the stay damper telescopic rod (hereinafter referred to as the rod)
When the window is fully closed, it slightly moves forward to pressurize the window strongly to prevent unexpected window opening, and as the window opening begins, it moves backward to the maximum at the top of the guide member. Sometimes it will be the longest stretch.

Next, when the fully opened window is pulled, the rod of the longest stretched stay damper retracts and begins to sink into the cylinder, and the roller at the slider end attached to the pedestal protruding from the lateral edge on the sash side, When it comes into contact with the arcuate surface of the guide member fixed to the window opening horizontal frame, the orientation of the stay damper becomes substantially parallel to the center line of the window opening horizontal frame, but at this point the force of pulling the window is released. It is important to note that the rod that has retreated until then starts stretching again and the fenestration starts. Therefore, when the roller comes into contact with the arcuate surface of the guide member and still pulls the window, the roller gets over the top of the guide member and descends and slides on the opposite inclined surface. In this case, the rod retreats most at the top of the guide member, but on the next inclined surface, it tries to move backward, so the stay damper moves through the slider of the gantry and the contact point of the roller at the end and the pivot point of the other pedestal. Since the window is tightly stretched, the window is kept in a fully closed state, but the position of the stay damper in this state is inclined with respect to the horizontal frame line of the window opening. Since the advancing force acts in a diagonal direction with respect to the window and a torsion moment is generated, in the present invention, the slider advancing parallel to the horizontal frame line of the window opening on the mount side causes the advancing force of the rod. So that it is parallel to the window It is obtained by successfully to eliminate the occurrence of torsional moment.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. In the case of a small width window W having a short width, the installation of an ammunition such as a stay damper in which a rod expands and contracts is limited to a single piece. In order to prevent accidental opening of the window when the window is closed, arranging the mounting position of the stay damper in an oblique direction with respect to the window surface so that the bullet pressure works even when fully closed is a common means of construction technology. That is, the L-shaped support base 1 is fixed to the horizontal frame R of the window opening H, and one end of the stay damper 10 is pivotally connected by the ball joint 12. Next, the horizontal frame E is attached to the horizontal edge E of the narrow window W. 2 is fixed, and another slider 3 that slides in parallel with the window surface is attached to the tip end side thereof by a plurality of setscrews 5.5, and the rod 11 of the stay damper 10 is attached to the ball joint 12 at one end thereof. The center line of the stay damper when fully closed is in different directions. And forms a clearly inclination angle with respect to the relationship on the window surface end is pivotally mounted. Therefore, the load acting in the tilt angle direction can be absorbed by the slider 3 so as to be parallel to the window W surface, and the twisting moment with respect to the window can be eliminated.

A roller 4 is pivotally attached to the other end of the slider 3 and slides on an arcuate surface 7 of a substantially L-shaped guide member 6 fixed to the horizontal frame R side of the window opening H immediately before closing the window. While climbing 9
The wall surface of the guide member 6 is formed in a substantially V shape so as to slide down on the inclined surface 8. In such a case, the rod 11 of the stay damper 10 retreats to the maximum when the roller 4 reaches the top 9 of the guide member, and becomes the starting point of the next forward movement, so that the position of the top 9 is located before the fully closed point. Therefore, the window pulled toward the closing direction is set so that after the roller 4 reaches the summit 9, the rod 11 starts to move forward, so that the inclined surface 8 slides down naturally and stops completely.
At this point, the ammunition pressure is working sufficiently, so unexpected (gust, gust,
It does not open the window due to impacts, etc., and it does not generate a twisting moment, so the window can be held very safely.

(Effect of the Invention) According to this invention, a special function that does not generate a twisting moment in the window when the small width window with a short width where the stay damper is limited to a single installation is fully closed is established by an extremely simple structure. As a result, excellent effects can be obtained, such as preventing the entry of wind and rain, or keeping the temperature cold.
