【Example】

 1 and 2 show that the upper and lower window shoji (17), (18) are attached to the right vertical frame (viewed from the inside) (19) of the window frame by the right side surface (viewed from the inside). The window screens (17) and (18) are completely opened in FIG. 1 and completely closed in FIG.

A pair of vertical drive rods (20) for opening and closing the window shoji (17), (18) are assembled to a pair of vertical frames (19) facing each other in a vertically movable manner to form a worm gear mechanism. It is moved up and down by the handle (62) via (21).

Hinge arms (22) are fixed to the upper ends of both sides of the upper window shoji (17) by the fixing portions (23), and the upward extending portions (24) from the fixing portions (23). ) Is pivotally attached to the upper end of the drive rod (20) by a lateral first pivot (25).

One end of the support arm (26) is pivotally connected to the fixing portion (23) of the hinge arm (22) by a connecting means, and the other end is laterally attached to the mounting seat (27) by a second pivot shaft. It is pivotally attached at (28) and the mounting seat (27) is fixed to the vertical frame (19) of the window.

When the drive rod (20) is in the highest position (FIGS. 2 and 3), the window shoji (17) is completely closed, and when the drive rod (20) is lowered from the highest position, the window is closed. The shoji (17) descends while rotating in the opening direction around the pivot (25) by the hinge (22) and the support arm (26). When the window shovel (17) reaches a predetermined maximum opening angle, the stopper (29) integral with the hinge arm (22) hits the support arm (26) to move the window shovel (17) to that position. Stop at an angle (Fig. 3). When the drive rod (20) rises backward from the lowered position, the window shovel (17) rotates in the closing direction around the pivot (25) via the hinge arm (22) and the support arm (26). Ascends and returns to the closed position (Figs. 1 and 3).

As shown in FIG. 5, the connecting means includes a connecting hole (32) formed by an enlarged circular hole (30) and a narrow straight hole (31) communicating with this hole, and a connecting hole (32) with respect to the center of rotation. And symmetrically arranged arc-shaped outer peripheral end faces (33) that rotate along the inner peripheral surface of the enlarged circular hole (30) and these outer peripheral end faces are flat surfaces in a narrow parallel relationship with each other. It is composed of a connecting pin (35) having a substantially rectangular cross section formed by a pair of side faces (34) that are connected to each other and fitted into the straight hole (31). The connecting hole (32) is bored in the hinge arm (22), the connecting pin (35) is erected laterally in the supporting arm (26), and is connected to the straight hole (31) of the connecting hole (32). The direction of the center line connecting both outer peripheral end faces (33) of the connecting pin (35) and the side faces (34) of the connecting pin is the vertical direction when the window shoji (17) is in the closed position. Are arranged to take.

When the window shoji (17) is completely closed (FIG. 3), the side surface (34) of the connecting pin (35) fits into the straight hole (31) of the connecting hole (32). , The hinge arm (22) and the support arm (26) are locked so that they cannot rotate relative to each other. At this time, even if the shoji (17) is opened, the hinge arm (22) and the support arm (26) cannot rotate around the pivots (25) and (28), and the window shoji ( 17) is locked in the closed position and this locked state is maintained. The connecting means by the connecting hole (32) and the connecting pin (35) can perform not only the locking function for the window shoji (17) but also the pulling function, so that the window shoji (17) is in a locked state. If the position of the airtight means is positioned between the window shovel and the window frame so that the airtight means operates in, the window shovel (17) is locked and at the same time airtight is obtained.

When the window sliding door (17) is open (FIG. 3), the connecting pin (35) has its outer peripheral end surface (33) rotatable along the inner peripheral surface of the enlarged circular hole (30). , Fits in the enlarged circular hole, and functions like the original pivot.

When the drive rod (20) is lifted in the open state of the window shovel (17) (FIG. 1) to close the window shovel (17), the connecting pin (35) is connected at its outer peripheral end surface (33). Enlargement of hole (32) Rotate along the inner peripheral surface of hole (30) (Fig. 3). When the window shoji (17) reaches the closed position, the side surface (34) of the connecting pin (35) is aligned with the straight hole (31) of the connecting hole (32). When the window sliding door (17) is completely closed, it only rises without rotation, and as a result, the connecting pin (35) moves relative to the direction from the enlarged circular hole (30) to the straight hole (31). Then, the side surface (34) of the connecting pin is guided by the straight hole (31) and fitted therein (FIG. 3). As a result, the upper end of the window shoji (17) is automatically locked and kept airtight as described above.

In this locked state, when the drive rod (20) is lowered, in the first stroke, the window screen (17) does not rotate but only descends, while the side surface (34) of the connecting pin (35) is lowered. It moves along the straight hole (31) of the connecting hole (32) and moves out of the straight hole (31) to reach the enlarged circular hole (30) relatively (Fig. 3). At the same time, the lock between the hinge arm (22) and the support arm (26) is automatically released, and the window screen (17) can be opened.

The connecting means between the hinge arm (22) and the supporting arm (26) will be described in more detail with reference to FIG.

The hinge arm (22), from the fixing portion (23) to the extending portion (24), is formed by a strip-shaped plate having substantially the same width when viewed from the front. The fixing portion (23) extends in the vertical direction so as to be parallel to the side surface of the window screen (17), and the fixing portion (23) is provided with a connecting hole (32). The extension portion (24) extends obliquely upward and rightward from the upper end of the fixing portion (23) in the direction of the drive rod (20) and is pivotally attached to the drive rod (20) by a pivot shaft (25).

The fixed portion (23) of the hinge arm (22) has a raised wall (36) formed by bending the central portion thereof into a U shape. The connecting hole (32) is formed in the raised wall (36), and the raised wall (36) is formed in the middle of the gap between the vertical frame (37) of the window shoji (17) and the vertical frame (19) of the window. (FIG. 6) to facilitate the connection of the hinge arm (22) and the support arm (26) by the connecting pin (35) and the opening and closing of the window shoji (17).

The enlarged circular hole (30) and the straight hole (31) of the connecting hole (32) are arranged in the longitudinal direction along the center line of the raised wall (36) of the fixed portion (23) of the hinge arm (22). The position of the connecting hole (32) and the processing, assembly, and mounting can be accurately and easily performed.

The raised wall (36) further has the stopper (29) bent at a right angle on its side, and this stopper (29) engages with the side of the support arm (26). Thus, the opening angle between the hinge arm (22) and the support arm (26) is limited as described above. The hole (38) of the fixing portion (23) of the hinge arm (22) is used for a mounting screw for fixing the hinge arm (22) to the vertical frame (37) of the window shovel (17).

The extending portion (24) is bent so that a step is formed between the extending portion (24) and the fixing portion (23), and the tip end of the extending portion (24) is pivotally attached to the drive rod (20) by the pivot shaft (25). ing. This step also provides a clearance for mounting the restraint between the window frame vertical frame (37) and the window vertical frame (19).

Similarly to the hinge arm (22), the support arm (26) is also formed by a strip plate having the same width from the connecting pin (35) to the pivot (28). In this support arm (26), the portion (39) that supports the connecting pin (35) overlaps the fixed portion (23) of the hinge arm (22) when the window screen (17) is closed. Like the fixing part (23) of the lever, it extends vertically so as to be parallel to the drive rod (20) and the vertical frame (37) of the window shovel (17). A square hole (40) is bored in the support portion (39) of the connecting pin (35), and the square shaft (41) of the connecting pin (35) is inserted into this square hole so that the end portion of It is tight. The center line connecting the outer peripheral end faces (33) of the connecting pins (35) is oriented vertically along the vertical center line of the hinge support portion (39), and is similar to the connecting hole (32). , Positioning of the connecting pin (35), processing, assembling, and mounting can be performed accurately and easily.

The extending portion (42) from the end of the support portion (39) of the connecting pin (35) to the pivot shaft (28) extends obliquely downward to the right in the direction of the drive rod (20) and has a step at the tip thereof. It is bent so as to form a step, and its tip is pivotally attached to the mounting seat (27) by the pivot (28). Similar to the step of the hinge arm (22), this step forms a gap for attaching a restraint between the vertical frame (37) of the window screen (17) and the vertical frame (19) of the window.

The line segment connecting the axis (25) -the axis (28) -the connecting pin (35) -the axis (25) always forms a triangle regardless of whether the window shoji (17) is open or closed. Since (35) is positioned so as to project in the opening direction of the window shoji (17) from the line segment connecting the axis (25) and the axis (28) (Fig. 3), follow the vertical movement of the drive rod (20). The hinge arm (22) and the support arm (26) can be opened and closed smoothly.

The lower ends on both sides of the upper window shoji (17) are also automatically locked when the window shoji (17) is closed by the second locking means, and the lock is automatically released when the window shoji is opened. It

The second lock means is composed of a lock pin (43) and a lock plate (44), and the lock pin (43) is fixed to the vertical frame (37) on the side surface of the shoji (17). Standing laterally at 45), the lock plate (44) is pivotally attached by a lateral pin (47) to a mounting seat (46) fixed to the vertical frame (19) of the window.

The lock plate (44) has a straight hole (48) which is opened in the lower side and extends in the longitudinal direction. The straight hole (48) is provided when the lock plate (44) is in the lock position. It is oriented vertically and, conversely, it is oriented diagonally when in the unlocked position.

In FIG. 3, when the shoji (17) is completely closed, the lock pin (43) fits into the straight hole (48) of the lock plate (44) and the lock plate (44). Is held in the locked position indicated by the solid line against the gravity thereof, and at the same time, the stopper (49) of the mounting seat (45) supports the lower side of the lock plate (44). As a result, the lock pin (43) is locked by the lock plate (44), and as a result, the lower end of the shoji (17) is locked at the same time as the upper end. Similar to the connecting means by the connecting hole (32) at the upper end of the shoji (17) and the connecting pin (35), this locking means also has a pulling function for airtightness in addition to the locking function. become.

When the shoji (17) is open, the lock plate (44) rotates by its gravity around the pin (47) to the position of an imaginary line (FIG. 3), and the hypotenuse (50) of the lock plate (44) moves. It hits the stopper (51) of the mounting seat (46) and is held in that position. In this case, since the straight hole (48) is inclined leftward and faces downward, and the right side of the straight hole (48) is formed longer than the left side, the opening end of the right side goes downward beyond the opening end of the left side. Waiting in the extended position.

When the shoji (17) rotates in the closing direction as the drive rod (20) rises, the lock pin (43) hits the right side of the straight hole (48) of the lock plate (44), and the lock plate Rotate the knob counterclockwise around the pin (47). When the shoji (17) reaches its closed position, the straight hole (48) of the lock plate (44) is oriented vertically, and the stopper (49) of the mounting seat (45) is located at the lower side of the lock plate (44). Reach the position below. In the closed position, the shoji (17) is pulled up to the completely closed position without rotating even if the drive rod (20) is raised. As a result, the lock pin (43) rises along the straight hole (48) and fits in this straight hole. In this way, the lower end of the shoji (17) is automatically locked. At this time, the stopper (49) of the mounting seat (45) also supports the lower side of the lock plate (44).

When the drive rod (20) is lowered to open the shoji (17), the shoji (17) descends without rotating, and the lock pin (43) is attached to the right side of the straight hole (48). Is engaged but is lowered to a position off the left side. Next, the shoji (17) is rotated in the opening direction, and the lock pin (43) is moved away from the lock plate (44). As a result, the lock by the lock pin (43) and the lock plate (44) is automatically released.

The connecting means consisting of the connecting hole (32) and the connecting pin (35) applied to the pivot point between (26) is constructed in the same way as used for the upper shoji (17) and the lower shoji (18). Like the upper shoji (17), the upper end of the lock is automatically locked and released, and is pulled and pulled (Fig. 3). However, the hinge arm (22) is not attached to the upper end of the drive rod (20) but is pivotally attached to the middle of the hinge arm (22) by a pivot (25). The locking means at the lower end of the lower shoji (18) is also different from that of the upper shoji (17) as follows.

As shown in FIG. 4, the lock means at the lower end of the lower shoji (18) is composed of a lock pin (52) and a lock cam (53) having a pressing surface. The lock pin (52) is erected laterally on the mounting seats (54) fixed to both sides of the shoji (18), and the lock cam (53) is erected on the crank arm (55). ) Rotates from one vertical frame (19) of the window around the other vertical frame (not shown) rotation transmission shaft (56) integrally with this shaft.

The crank arm (55) is connected to the transmission rod (57), and the transmission rod is sequentially attached to the operation arm (59) of the worm gear (58) by lateral pins (60) and (61). It is pivotally mounted and meshes a worm gear (58) with a worm (not shown) that rotates integrally with the shaft of the handle (62). The crank arm (55) and the transmission rod (57) are further pivotally attached by a pin (60) common to the transmission rod (63), and the transmission rod (63) is attached to the lower end of the drive rod (20) by a pin (64). It is pivotally attached. When the handle (62) is rotated, the worm and the worm gear mechanism (58) of the worm gear (58) move from the worm gear mechanism (21) through the operating arm (59) and the transmission rods (57), (63). The drive rod (20) moves up and down to simultaneously open and close the upper and lower shoji (17), (18). The transmission shaft (56) drives the crank arm (55), the transmission rod (63) and the drive rod (20) on the opposite side of the shoji (18), and has a common operating arm (59). And it is rotated by the transmission rod (57).

In FIG. 2, the lower shoji (18) is completely closed, and the lock surface of the lock cam (53) of the crank arm (55) meshes with the lock pin (52) of the mounting seat (54) ( Figure 4), locking the lower end of the shoji (18) and pulling it to provide air tightness.

In this closed state, when the operating arm (59) of the worm gear (58) is rotated around the pivot shaft (66) by the handle (62), the crank arm is moved through the transmission rod (57). The cam (55) also rotates counterclockwise together with the transmission shaft (56), and the lock cam (53) of the crank arm moves away from the lock pin (52) of the mounting seat (54) (Fig. 3). This automatically unlocks the lock cam (53) from the lock pin (52). As a result, the shoji (18) can be opened as shown in FIG.

When the shoji (18) is closed from the state shown in FIG. 1, the lock pin (52) of the mounting seat (54) rotates counterclockwise around the pivot (25) and the lock cam of the crank arm (55). (53) rotates clockwise around the transmission shaft (56) (Fig. 4). Just before the shoji (18) is completely closed, the pressing surface of the lock cam (53) engages with the lock pin (52) and presses the pin (Fig. 4). As a result, the lower end of the shoji (18) is automatically locked and pulled.
