, 3, which fit into the fixed frame 4, as shown in FIG. 1, a center box 5 is fixed at the center of the vertical rod 2, and corner boxes 6.about.6 are fixed at the upper and lower corners.

The center box 5 has a vertical rod 2 as shown in FIG.
Sliders 8, 8 are installed in the upper and lower parts of the groove 7, which is vertically elongated along the vertical axis and penetrated vertically, so as to be slidable in the longitudinal direction. A substantially semicircular notch 9 is formed in the notch 9, and a crescent lock 10 is provided in the notch 9.

The crescent lock 10 has protrusions 13 arranged in series on a circular base plate 12 with an elongated hole 11 in the center, mounting holes 14 for attaching the slider 8 to both ends of the protrusions 13, and an arc-shaped outer circumference of the base plate 12. It is attached to the box 5 with a pin 16 passing through the elongated hole 11 so that it can rotate and move freely in the longitudinal direction of the elongated hole 11, and one mounting hole 14 is formed with a pin 17. It is connected to the slider 8.

Since the crescent lock 10 is equipped with two mounting holes 14, the required rotation direction can be selected depending on the forward and backward direction of the slider 8, and the elongated hole 11 causes a retraction movement at the end of rotation in the locking direction. The frictional resistance with the receiving metal fitting 18 during rotation can be reduced, the bundle operation is easy, and failures do not occur.

That is, as shown in FIGS. 9 and 10, the receiving fitting 18 is formed with an arcuate wall 18b standing up on the front edge of the surface of a rectangular mounting board 18a.

Further, the crescent lock 10 has a long hole 1 on the outer periphery of the circular base plate 12.
Parapets 15 and 15 are set up opposite each other on both sides of 1.
Protrusion 1 from one side between both battlements 15 and 15 on the outer periphery of base plate 12
3 stands out.

Therefore, the two parapet walls 15 of the crescent lock 10 form a gap between their corresponding surfaces that is wider than the width of the arcuate wall 18b, and the corresponding spacing between the ends of the two parapet walls 15, 15 with respect to the arcuate wall 18b is free. It will be possible to pass through the external fitting.

When the crescent lock 10 is in the unlocked position with respect to the receiver 18, both parapets 15 and 15 are connected to the vertical rod 2 or the horizontal rod 3.
The lock walls 15, 15 are opposed to each other along the longitudinal direction, and a gap corresponding to the ends of the lock walls 15, 15 is open with respect to the opening/closing rotation direction of the opening/closing frame 1.

In the closed position in which the opening/closing frame 1 is fitted into the opening/closing frame 1, the positional relationship between the chest wall 15.15 and the arcuate wall 18b is approximately coaxial as shown in FIG.

In this state, when the bundle 19 is rotated in the locking direction and the slider 8 is moved, the crescent lock 10 rotates counterclockwise in the case of FIG. 16, the crescent lock 10 is pushed outward along the elongated hole 11, and the chest wall 15 is rotated to the outside of the arcuate wall 18b.

When the rotation continues and the pin 17 passes through the horizontal line passing through the pin 16 of the slotted hole 11, the crescent lock 10 now moves to the pin 1.
7 in the direction of movement, and as a result the parapet 15 is pulled in the direction of movement of the arcuate wall 18
The opening/closing frame 1 is fixed to the fixed frame 4 by being press-fitted to the outside of the frame b.

Furthermore, when the bundle 19 is turned in the unlocking direction to open the opening/closing frame 1, the crescent lock 10 moves in the opposite direction to the above and returns to the unlocked position as shown in FIG. will be able to do so freely.

A bundle 19 for opening/closing operation is attached to the front surface of the central portion of the vertical rod 2.

As shown in FIGS. 4 and 5, this bundle 19 is rotatably supported by a base metal fitting 20 fixed to the vertical rod 2.
Inside the base metal fitting 20, there are provided a cam 22 attached to the bundle shaft 21 and a pair of claws 23 that vertically approach or separate from each other as the cam 22 rotates. When the bundle 19 is rotated, the upper and lower sliders 8 and 8 perform opposite vertical movements.

In the illustrated case, a spring 25 is provided at the center of the center box 5.
When the opening/closing frame 1 is placed in the open position with respect to the fixed frame 4, it protrudes from the opening/closing frame 1 and the claw 23
A latch 26 is provided to prevent the bundle 19 from being rotated when the opening/closing frame 1 is in the open position, and to prevent the crescent lock 10 from attaching to the receiver 18 while the opening/closing frame 1 is in the open position. It is designed to prevent collisions and damage.

The structure of the latch 26 and pawl 23 is as shown in FIG.
It is formed in a planar shape with a toe 23b facing the slider 8 on the side edge of the slider 8, and the toe 23b of both claws 23.23,
23b faces the upper and lower positions sandwiching the latch 26, and the toe 23b of the upper claw 23 is the upper slider 8 and the pin 24.
The tips 23b of the lower claws 23 are connected to the lower slider 8 by pins 24, respectively.

Further, at the inner end of the latch 26, there is a claw 23b that is long in the vertical direction and that opens the crescent lock 10 vertically when it is in the unlocked position.
A baffle plate 41 having a length that fits exactly between and 23b is fixed.

This baffle plate 41 moves together with the movement of the latch 26 to move in and out between the upper and lower toes 23b, 23b, and when the latch 26 protrudes to the outer surface of the center box 5, the baffle plate 41 moves upward and downward. The toes 23b, 23b that separate
The claws 23 and 23 are located between the two claws 23 and 23, and are restrained from moving in the approaching direction, so that the bundle 19 cannot be rotated in the direction in which the crescent lock 10 is locked.

Furthermore, when the latch 26 is retracted into the center box 5, the baffle plate 41 that has moved together with the latch 26 separates from between the upper and lower toes 23b, 23b, as shown by the dashed line in FIG. The restraints are released and the claws 23, 23 are allowed to move toward each other.

The corner boxes 6 and 6 are connected to the vertical rod 2, as shown in FIG.
The crescent lock 10 is bent at a right angle from the middle part along the outer surface of the horizontal rod 3, and a crescent lock 10 is attached to the outer surface of both ends with a structure similar to that of the center box 5. Sliders 28, 29 for rotating the lock 10 are provided so as to be slidable in the longitudinal direction.

Vertical slider 2 in corner box 6.6 above
8 and the slider 8 of the center box 5, and both sliders 28 and 29 of the corner box are respectively interlocked via the interlocking mechanism 30, so that all the crescent locks 10 can be rotated simultaneously by operating the bundle 19. It has become.

As shown in FIG. 2, the vertical part interlocking mechanism 30 includes a fine adjustment tool 32 using a tongue buckle 31 and a pair of rack rods 33.
It is formed using two types of large adjusters 35 which are engaged with each other within the cover 34, and the length can be freely adjusted with respect to the vertical arrangement interval of the crescent lock 10.

In addition, the interlocking mechanism 30 that connects the sliders 28 and 29 of the corner box 6 has a plurality of springs 36 with different diameters fitted inside and outside, as shown in FIGS. It is formed using a transmission member 37 with the opposite characteristics.

Since this member 37 has little stretchability and sufficient flexibility, it is suitable for transmitting motion at the bent portion.

Note that the opening/closing frame 1 shown in the figure is used for a window that opens on one side, and metal fittings 18 are attached to the inner peripheral surface of the fixed frame 4 at positions corresponding to each crescent lock 10, but it can also be used for a window that opens on both sides or It may also be used for doors, and in the case of this double-opening type, a receiving metal fitting may be attached to the vertical lever of the opposite opening/closing frame, and a crescent lock that rotates with a bundle may be attached to the upper and lower horizontal levers.

This device has the structure described above, and its operation will be explained next.

A center box 5 and a corner box 6 are fixed to the opening/closing frame 1 constituting the window, a crescent lock 10 is attached to a predetermined position of each box, each slider is connected by an interlocking mechanism 30, and each crescent lock is attached to the fixed frame 4. A receiving metal fitting 18 is fixed at a position corresponding to 10.

The attachment of each crescent lock 10 to the slider through the attachment hole 14 is selected so that the movement of each slider 8, 28, 29 due to the rotation of the bundle 19 causes it to rotate in unison.

When the opening/closing frame 1 is in the open position, each crescent lock 10 is in an open state with respect to the receiving metal fitting, and when the opening/closing frame 1 is placed in the fixed frame 4 and closed in this state, each crescent lock 10 and the receiving metal fitting 18 are opened. corresponds, the latch 26 is recessed, and the bundle 19
rotation is possible.

When the bundle 19 is rotated, the upper and lower claws 23 are drawn together, the slider 8 of the center box 5 moves to the center, and this movement causes the crescent lock 10 of the center box 5 to rotate.

Further, the movement of the slider 8 is transmitted to the sliders 28 and 29 of the corner box 6 by the interlocking mechanism 30, and both sliders 28 and 29 in this box 6 move together via the transmission member 37, and the crescent locks of the vertical and horizontal portions are moved together. 1
0 rotates.

Therefore, all the crescent locks attached to the opening/closing frame 1 are engaged with the receiving metal fittings at the same time, and the fixed frame 4 and the opening/closing frame 1 are drawn together to achieve a complete seal.

Further, in order to open the window, it is sufficient to turn the handle 19 in the opposite direction to the direction in which it is closed, and all the crescent locks are brought into the open state with respect to the metal fittings at the same time.

As described above, according to this invention, crescent locks are attached to the outer surfaces of the vertical rod and the upper and lower horizontal rods of the opening/closing frame, and the sliders that rotate each crescent lock are interlocked by an interlocking mechanism.
Since all crescent locks are rotated by rotating the handle attached to the vertical rod, the vertical part and the upper and lower horizontal parts can be tightened at the same time, greatly improving the sealing effect of doors and windows. Moreover, all the crescent locks can be operated at the same time with one handle, making opening and closing operations easy.

In addition, the interlocking of the slider in the vertical and horizontal parts is performed by a transmission member in which multiple springs are fitted in order in the corner part and the directionality of each spring is reversed in turn, so that in the part bent at right angles, It can also smoothly transmit linear motion, and pulling and pushing motions can also accurately rotate horizontal rod crescent locks.
