 1 to 3 show a raising and lowering window. The raising and lowering window is a window frame in which upper and lower horizontal frames 1 and 2 and a left and right vertical frame 3 are framed in a rectangular shape, and upper and lower doors are arranged in a staggered manner indoors and outdoors. 4 is arranged.

On the inner surface of the vertical frame 3 of the window frame, as shown in FIGS. 3 and 4, groove-shaped guide portions 5 for sliding the respective raising / lowering doors 4 are formed indoors and outdoors. As shown in FIG. 6 (a), a lock receiver 6 is screwed and fixed to the bottom wall 5a of each guide portion 5 at a predetermined position where the sliding of the raising / lowering door 4 should be locked. A receiving groove 7 is formed in the center of the lock receiver 6, and inclined surfaces 8 are formed from the upper and lower portions of the opening end of the receiving groove 7, respectively.

Further, as shown in FIGS. 3 and 5, a receiving wall 10 for receiving an outdoor side surface of the raising / lowering door 4 is formed on each outdoor side of the indoor and outdoor guide portions 5.

On the other hand, guide bodies 11 that engage with and disengage from the guide portions 5 of the vertical frame 3 are attached to the corners of the upper and lower doors 4 at both upper ends thereof, and rotary shafts are provided on both sides of the lower end of the doors 4. 12 is provided so as to project laterally, and the rotating shaft 12 is rotatably supported by a slider 13 arranged in the guide portion 5 of the vertical frame 3 (see FIGS. 2 and 3).

The guide body 11 is formed of a case-shaped guide body main body 11a and an engagement body 11b that is retractably housed in the guide body main body 11a.

As shown in FIG. 5, the guide body 11a is formed with a storage portion 14 for the engagement body 11b. An end portion of the storage portion 14 on the vertical frame 3 side is opened to the outside, and a compression spring 16 is arranged at the other end, and communicates with the storage portion 14 on the indoor side surface of the guide body 11a. A communication groove 17 is formed. A fixing piece 18 is formed on the indoor side so as to project from the end of the guide body 11a on the compression spring 16 side.

The engagement body 11b is formed in a rod shape, and is connected to the operation member 26 arranged on the indoor side surface of the guide body main body via the connection portion 19 provided in the communication groove 17, and the engagement body 11b of the engagement body 11b. The front end outdoor side surface 20 on the projecting side is formed obliquely, and a spring pressing piece 21 engageable with the compression spring 16 of the storage portion 14 is formed at the other end.

Further, as shown in FIG. 6 (a), a spring piece 22 having a chevron-shaped engaging portion 23 is formed on the inner bottom surface of the central portion of the accommodating portion 14 of the guide body 11a. Correspondingly, a recess 24 for accommodating the engaging portion 23 is formed on the lower surface of the engaging body 11b. Further, an inverted trapezoidal protrusion 25 is formed in the recess 24.

With the above configuration, the engaging body 11 b can slide within the range in which the engaging portion 23 can move in the recess 24, and the sliding is performed by the operating member 26, and the engaging body 11 b operates the operating member 26. Thus, the guide body 11a can be made to project to a two-step projecting position described later, or the compression spring 16 of the storage portion 14 can be pressed by the spring pressing piece 21 to be retracted into the storage portion 14.

That is, when the operating member 26 is slid to press the compression spring 16 with the spring pressing piece 21, the engaging portion 23 of the spring piece 22 is engaged with one end of the recess 24 (FIG. 6A). At this time), the engagement body 11b is retracted into the storage portion 14, and the tip of the engagement body 11b is disengaged from the guide portion 5 of the vertical frame 3. Since the upper end of the door 4 loses its support by the vertical frame 3, it can be tilted substantially horizontally toward the indoor side about the pivot shaft 12 at the lower end as shown by the dotted line in FIG. 2, and the outdoor surface of the glass can be wiped clean. can do. When the operation member 26 is operated against the compression spring 16, it is easy to operate by putting one finger on the fixing piece 18 and the other finger on the operation member 26.

Next, when the hand is released from the operating member 26, the engagement body 11b is returned to the first projecting position (the position shown by solid line in FIG. 3B and FIG. 3) by the compression spring 16. The engaging portion 23 of the spring piece 22 engages with the protrusion 25 of the recess 24. At this time, the tip of the engaging body 11b engages with the guide portion 5 of the vertical frame 3 and retracts from the lock receiver 6, and as shown in FIGS. 4 and 5, the indoor side surface 27 of the engaging body 11b and the guide body 11b. The outdoor side shoulder portion 28 of the main body 11a is held between the indoor side opening edge 29 of the guide portion 5 of the vertical frame 3 and the receiving wall 10, and the raising / lowering door 4 is slid and guided in this state. You can open and close the windows.

When the operating member 26 is further slid on the side opposite to the compression spring 16 by applying a force, the spring piece 22 bends and the protrusion 25 rides over the engaging portion 23, engaging the opposite end of the recess 24. 6 (c) and the second protruding position shown by the dotted line in FIG. 3, and the tip of the engaging body 11b engages with the receiving groove 7 of the lock receiver 6, so that the raising / lowering door 4 is shown in FIG. It is locked so that it cannot slide, as in c). At this time, the engaging portion 23 of the spring piece 22 of the guide body 11a is held between the recess 24 and the protrusion 25 of the engaging body 11b and does not move unintentionally. To release the lock, the engagement body 11b may be moved to the first protruding position. At this time, the engaging portion 23 of the spring piece 22 is held between the recess 24 and the protrusion 25.

By the way, when the raising / lowering door 4 tilted as described above is engaged with the guide portion 5 of the vertical frame 3 again, the raising / lowering door 4 is turned upward and raised. At this time, as shown in FIG. 7, the outdoor surface 20 at the tip of the engaging body 11b at the first protruding position hits the vertical frame 3, but since the outdoor surface 20 is formed obliquely, 11b is pushed into the guide portion 5 against the compression vane 16, and the outdoor side surface of the vertical frame 3 of the door 4 (which is flush with the outdoor shoulder portion of the guide body 11a) is received by each guide portion 5. It abuts the wall 10 and the rotation is forcibly stopped. At the same time, when the engagement body 11b faces the guide portion 5 of the vertical frame 3 as shown in FIG. 5, the compression spring 16 moves to the first position again to engage the guide portion 5.

Further, when the engaging body 11b is not in the position of the lock receiver 6 and is slid in a state of being projected to the second projecting position, the tip of the engaging body 11b abuts the lock receiver 6, but is formed obliquely. Since the engaging body 11b is pushed into the guide body 11a by the upper and lower slope portions 8 of the lock receiver 6, the guide body 11 and the lock receiver 6 are not damaged.
