[Problems to be solved by the device]

 Conventionally, when fixing the window to a certain amount, one hand is used to support the window and the other hand is used to fix the stopper, so both hands must be used to fix the window. The operability was not good. Further, since the handle and the stopper are attached to the interior side of the window in an exposed state, the appearance from the interior side does not look neat and there is a risk that the design may deteriorate. In addition, when opening windows, there was a request that the windows be opened at a fixed amount for safety and aeration during normal times, but to be opened largely during maintenance (cleaning, etc.).

The present invention has been made in view of the above circumstances, and provides a window fitting that has both functions of a handle and a stopper, can be operated with one hand, and can be easily released from the regulation of the opening amount during maintenance. Therefore, the purpose is to improve the design and operability.

 Hereinafter, a preferred embodiment of a window fitting according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing a state in which a window fitting according to the present invention is closed, FIG. 2 is a rear view of a receiver, FIG. 3 is a side view showing a state in which the window fitting is open, and FIG. FIG. 5 is a side view showing the above, and FIG. 5 is a plan view showing the connecting means.

As shown in FIG. 1, a receiver 3 having a base 3a is fixed to the inner surface of the lower portion of the window frame 1 with a screw via the base 3a. As shown in FIG. 2, a pair of supporting pieces 3b facing each other are formed on the base 3a of the receiving tool 3 so as to project to the indoor side. A support hole 3c is formed on the tip side of the support piece 3b projecting on the indoor side so as to penetrate therethrough. As shown in FIG. 3, a first shaft (fixed shaft) 5 extending in the horizontal direction is fitted into the support hole 3c, and the base end side of the plate-shaped arm 7 is rotated by the fixed shaft 5 between the support pieces 3b. It is supported freely. A second shaft (moving shaft) 9 extending in the horizontal direction is fitted on the tip side of the arm 7, and the base end side of a handle 11 is rotatably supported on the moving shaft 9. The grip 11 is formed with a sandwiching portion 12 for accommodating the arm 7 when the arm 7 swings inwardly around the fixed shaft 5 (see FIG. 1). That is, when the arm 7 is swung to the indoor side, the arm 7 is housed in the handle 11 and integrated.

On the other hand, as shown in FIG. 1, a bracket 15 is fixed by a screw to the indoor surface of the lower portion of the window 13, and the bracket 15 is provided with a support piece 15a protruding toward the indoor side. As shown in FIG. 4, a connecting hole 15b is formed in the supporting piece 15a, and the connecting hole 15b is opened by a notch 15c cut out along the outer edge of the supporting piece 15a. Further, the notch width dimension of the notch 15c is smaller than the inner diameter dimension of the connecting hole 15b.

As shown in FIG. 5, a gripping groove 11 a into which the support piece 15 a of the bracket 15 is inserted is formed at the tip of the handle 11 whose base end side is supported by the arm 7. A horizontally extending connecting shaft 17 is provided in the inserting groove 11a so as to traverse the connecting shaft 17, and a large diameter portion 17a and a small diameter portion 17b are formed in the connecting shaft 17. The large-diameter portion 17a has a dimension D that fits into the connecting hole 15b of the bracket 15, and the small-diameter portion 17b has a small dimension d that fits into the notch 15c. A button 19 is coaxially protruded from one end of the connecting shaft 17, and the button 19 projects from the side surface of the handle 11. The connecting shaft 17 is movable in the axial direction and is biased by a spring 21 in the protruding direction of the button 19. By being biased by the spring 21, the connecting shaft 17 is normally arranged such that the large diameter portion 17a is located in the sandwiching groove 11a. Then, when the button 19 is pressed, the connecting shaft 17 moves in the axial direction H against the urging force of the spring 21, and the small diameter portion 17b is arranged in the insertion groove 11a. That is, in the connecting shaft 17, the small diameter portion 17b arranged in the inserting groove 11a is fitted into the notch 15c, and the large diameter portion 17a is aligned with the connecting hole 15b by the urging force of the spring 21, so that the connecting piece 15a is pulled out. It engages irremovably. The connecting shaft 17, the spring 21, and the bracket 15 constitute a connecting means 23.

As shown in FIG. 1, a protrusion 25 is provided in the inside of the handle 11 on the distal end side so as to protrude toward the connecting shaft 17. The protrusion 25 is configured to press the support piece 3b of the receiving tool 3 when the arm 7 is housed inside the handle 11. That is, when the projection 25 presses the support piece 3b, the handle 11 receives a reaction force in the indoor direction from the window frame 1, and this reaction force causes the window 13 to move toward the window frame 1 side via the connecting shaft 17 and the bracket 15. Be attracted to. Therefore, even if the wind pressure P acts on the window 13, the projection 25 is in contact with the support piece 3b, so that the window 13 is securely fixed (locked) to the window frame 1 side.

A window fitting 31 according to the present embodiment is configured with the receiver 3, the arm 7, the handle 11, the bracket 15, and the connecting shaft 17 as main members.

In the window fitting 31 having such a structure, when the handle 11 is moved in the B direction, the lock is released, and when it is further moved in the C direction, the arm 7 is rotated around the fixed shaft 5 and the grip is held. The hand 11 is pushed out to the outside of the room and the window 13 is opened (see FIG. 3). Then, the arm 7 and the handle 11 pushed out to the outside of the room form a substantially straight line, and hold the window 13 as an integrated stopper. Further, when the handle 11 is moved in the E direction when closed, the arm 7 moves in the F direction, and the arm 7 and the handle 11 which are in a straight line are bent at the moving shaft 9 and the arm 7 is centered around the fixed shaft 5. Is rotated, and the arm 7 is stored in the handle 11 (see FIG. 1). When the arm 7 is housed in the handle 11, the protrusion 25 presses the support piece 3b, and the window 13 is pulled toward the window frame 1 side. When the button 19 is pressed when the restriction of the opening amount of the window 13 is released, the small diameter portion 17b is placed in the insertion groove 11a, the small diameter portion 17b passes through the notch 15c, and the connecting shaft 17 is supported by the support piece. 15a is removed, the connection between the window 13 and the window frame 1 is released, and the window 13 can be freely opened.

In the window fitting 31 according to the present embodiment, the so-called push-up type window 13 has been described by taking an example in which the arm 7 and the handle 11 expand and contract on the vertical plane. In this window, the arm 7 and the handle 11 may be used so as to expand and contract on a horizontal plane.
