Description

  The present invention relates to an opening / closing device for easily opening and closing a sliding door when a handle is put on a handle and a building opening using the same.

  In recent years, in order to improve the airtightness of the room, the space between the vertical wall of the sliding door and the window frame or the opening frame (hereinafter referred to as the window frame including the opening frame in this specification). There is a tendency that an airtight holding means such as interposing an airtight member such as a bead or a concave-convex fitting is provided. In addition, when sliding doors using synthetic resin window fences for double glass structure are used to improve heat insulation from the viewpoint of energy saving during cooling and heating and noise insulation against noise pollution, The width is large. When trying to open these sliding doors from a sealed state, since the adhesion between the door tips and the window frame is high, the resistance at the time of opening is large, and a strong force is required at the time of initial movement. Therefore, the reality is that it is not easy for elderly people and children to open the sliding door.

As a means to cope with this, for example, Patent Document 1, as shown in FIG. 10, and 11, the force point (a ₀₎ at one end, the point at the other end of the (b _0), the intermediate When the lever handle (01) having a fulcrum (c ₀ ) is applied to the force point (a ₀ ) and the force F ₀ in the direction to open the sliding door (02) is applied to the force point (a ₀ ), the action point (b ₀ ) An opening / closing device (05) for the sliding door (02) is disclosed that is pivotally attached to the window tile (04) on the door tip side at the fulcrum (c ₀ ) so as to abut on the frame (03).
When the sliding door (02) is opened, only a small force is applied to the lever handle (01), the action point (b ₀ ) abuts against the window frame (03) and pushes it. The sliding door (02) can be moved by force.
Japanese Patent Laid-Open No. 9-256663 (see paragraph [0005], FIG. 1 and FIG. 3)

The method described in Patent Document 1 has an advantage that the sliding door can be moved with a small force, but has the following problems. That is, since the operating point (b ₀ ) of the lever handle (01) abuts on the same part of the window frame (03) every time the sliding door (02) is opened, the part is easily damaged. In particular, since the window frame (03) made of synthetic resin is easily damaged, it is necessary to fix the metal backing plate (06) to the portion. Moreover, in order to improve the appearance of the finish, it is necessary to form a recess for fitting the metal backing plate (06) into the window frame (03) so as not to protrude from the surface of the window frame (03). Don't be. These operations must be performed in consideration of the height of the window and the like, and are performed at the construction site. As a result, the number of processes in the field increases.

In addition, the thickness of the window frame (03) in the indoor / outdoor direction varies depending on the size of the window, the material of the window frame (03), etc., so if the window frame (03) is thin, The action point (b ₀ ) of the handle (01) rotates more indoors or outdoors than the window frame (03) and does not contact the window frame (03) accurately. Therefore, the metal backing plate (06) is attached by providing a special support structure on the indoor side of the window frame (03), or depending on the change in the thickness of the window frame (03), the action point (b ₀ ) Has to be dealt with by preparing a plurality of lever handles (01) having different heights (positions in the indoor and outdoor directions).
