Description

  The present invention relates to a raising / lowering window in which a movable shoji is provided on a window frame so as to be movable up and down.

Conventionally, various raising and lowering windows in which a movable shoji is provided on a window frame so as to be movable up and down are known.
For example, Patent Document 1 discloses a raising / lowering window in which movable shojis are provided to be movable up and down on the indoor side and the outdoor side of a window frame.
Specifically, the indoor and outdoor vertical grooves are formed in the left and right vertical frames of the window frame, and left and right support members (sliding members) are attached to the movable shojis. The movable shoji is slidable in the vertical direction along the window frame so as to be movable up and down between the closed position and the open position.

JP 2000-248843 A

In the conventional raising and lowering window described above, when the movable shoji is in the closed position, the door stop (door awning) comes into contact with the horizontal frame (upper frame, lower frame) of the window frame. The summon bowl is located in the middle of the window frame and does not contact the horizontal frame.
For this reason, the summing part of the movable shoji is positioned by the support member in the left-right direction (finding direction) and the indoor outside direction (forecast direction). It is necessary to reduce the space in the left-right direction and the space in the indoor / outdoor direction between the indoor outer end surface of the support member and the indoor inner surface of the vertical groove.
However, if each of the aforementioned gaps is small, the sliding resistance when the support member moves up and down increases, and the opening / closing force of the movable shoji increases.

  As mentioned above, in the raising and lowering window in which the support member attached to the movable shoji is movable up and down along the vertical groove of the vertical frame, the opening and closing force of the movable shoji is not heavy, and the movable shoji in the closed position is summoned The part cannot be reliably positioned in the left-right direction or the indoor outside direction.

  The object of the present invention is to raise and lower the sliding member attached to the movable shoji so that it can move up and down along the longitudinal groove of the vertical frame. Is a raising / lowering window that can be reliably positioned in the left-right direction and the indoor-outside direction.

The present invention enables the movable member to be moved up and down along the vertical groove of the vertical frame of the window frame by allowing the sliding member attached to the summing part of the movable frame to be in the closed position and the open position. In the raising and lowering window that is movable up and down, and the summing part is located in the middle of the window frame when the movable shoji is in the closed position,
A positioning member is inserted into the vertical groove of the vertical frame, and the sliding member is opposed to the positioning member in the left-right direction and the indoor-outer direction when the movable shoji is in the closed position, and is slid when the movable member moves toward the open position. Install so as to be separated from the moving member,
When the positioning member and the sliding member face each other, the gap in the left-right direction and the gap in the indoor outside direction are larger than the gap in the left-right direction between the sliding member and the longitudinal groove and the gap in the indoor outside direction, respectively. It is a raising and lowering window characterized by being small.

In the present invention, the sliding member includes a guide portion and a positioning portion positioned closer to the movable shoji closing position direction than the guide portion,
The guide portion is slidably guided along the longitudinal groove, and the positioning portion faces the positioning member,
It is preferable that the gap between the vertical groove and the guide portion is smaller than the gap between the positioning portion and the vertical groove.

  In this way, when the movable shoji is moved up and down, the guide portion slides along the longitudinal groove and the guide portion becomes a sliding resistance, but the positioning portion does not become a sliding resistance. Therefore, the sliding resistance of the sliding member does not increase, and the opening / closing force of the movable shoji can be reduced.

In the present invention, the vertical groove has two inner surfaces in the left-right direction opposite to each other in the left-right direction, and two inner surfaces in the indoor outer direction opposite to each other in the indoor outer direction,
The sliding member includes a guide portion and a positioning portion positioned closer to the movable shoji closing direction than the guide portion, and the guide portion has two left and right guide surfaces extending in the left and right direction and two inward and outward directions. It has a guide surface in the indoor outside direction, and the positioning part has a positioning surface in the left-right direction and a positioning surface in the indoor outside direction,
The positioning member has a support surface in the left-right direction and a support surface in the indoor outside direction,
The inner surface in the left and right direction of the vertical groove and the guide surface in the left and right direction, and the inner surface in the indoor outer direction and the guide surface in the indoor outer direction are opposed to each other so that the guide portion is slidably guided along the vertical groove,
The left-right positioning surface, the left-right support surface, the indoor-outside positioning surface and the indoor-outside support surface are opposed to each other and positioned in the left-right direction, the indoor-outside direction,
Preferably, the gap between the inner surface and the positioning surface is larger than the gap between the inner surface and the guide surface, and the gap between the positioning surface and the support surface is minimized.

In this way, when the movable shoji is moved up and down, each guide surface of the guide portion is slidably guided along each inner surface of the longitudinal groove, and each positioning surface of the positioning portion does not contact each inner surface of the longitudinal groove. The sliding resistance of the sliding member is reduced.
In addition, when the movable shoji is in the closed position, the positioning surface of the positioning portion and the support surface of the positioning member are opposed to the left and right directions, the interior and exterior directions, and the gap between the two is small. It can be accurately positioned in the indoor and outdoor direction.

  In the present invention, the positioning surface in the indoor / outdoor direction of the positioning portion and the support surface in the indoor / outdoor direction of the positioning member are inclined surfaces with respect to the vertical surface, and are in contact with each other to the sliding member in the indoor / outdoor direction. It is preferable that a pulling force toward the head acts.

  In this way, when the movable shoji is in the closed position, the summing part of the movable shoji is drawn toward the indoor exterior side, so that the airtightness and watertightness between the movable shoji and the vertical frame can be improved.

According to the present invention, when the movable shoji is moved up and down, the sliding member is slidably guided along the longitudinal groove, and the sliding member is separated from the positioning member without facing the positioning member. The sliding resistance is small and the opening and closing force of the movable shoji is light.
Further, when the movable shoji is in the closed position, the sliding member is positioned facing the positioning member in the left-right direction and the indoor outside direction, so that the summing part of the movable shoji can be reliably positioned in the left-right direction and the indoor outside direction.
