Description

[Detailed Description of the Invention] This invention relates to a window locking device that prevents the window from opening beyond a certain level.

Conventionally, windows using metal sashes maintain complete airtightness in the room, so if a ventilation system is not available, it is necessary to open the window to ventilate the room when the door is unlocked.

At this time, since the door is unlocked, there is a drawback that ventilation occurs in an unfavorable state from the security point of view.

The purpose of this invention is to provide a window lock device that restricts opening of a window to such an extent that no one can enter or exit.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In the figure, A is a tension member with an opening at the bottom that is fitted into the rail b of the window frame B to regulate the opening of the window C, and the length of the tension member A is the length of the window frame B. When one end of the stile is brought into contact with a doorstop and the vertical stile of the window C is brought into contact with the other end, the opening of the window C becomes such that no one can enter or exit.

In addition, the above-mentioned tension member A includes a top wall 1, a side wall 2 connected downward from both side edges of this top wall 1, and a narrow “↑J” projecting inwardly from the lower edge of this both side wall 2. However, the bottom wall 3 is not necessarily required.

At least in both ends of the tension member A, an engagement device is incorporated which fixes the tension member A to the rail b by a rotation operation using a key from the outside.

In the illustrated case, the above-mentioned securing device includes a base material 4 that is fitted from the end of the tension member A, and a groove portion 5 that is provided so that the rail b is fitted upward from the bottom surface of this base material 4. a notch 6 provided on both sides of the base material 4 so as to communicate with the groove 5;
A clamp pawl 7 that fits into both notches 6, a support shaft that fits into the through hole 8 of the base material 4 and the clamp pawl 7 so as to cross the notch 6, and a -L surface of the base material 4 and a groove. 5, an opening 11 provided in the top wall 1 so as to be aligned with the through hole 10, and this opening r-'111.
A cylindrical body 13 that is inserted into the through hole] 0 and fixed with a screw 12 that is screwed into the base material 4; a rotating body 14 that is assembled into this cylindrical body 13 and can be rotated by a key; Rotating body 14
A cam 15 is provided on the lower surface of the clamp claws 7 so as to spread the upper ends of the clamp claws 7.

In addition, instead of the above-mentioned clamp claw 7, a wedge-shaped slider (not shown) that presses against the side surface of the rail b may be used.

In the figure, 16 is a recess provided on the side surface of the base material 4, and 17 is a recess 16.
A leaf spring whose end is fitted into the spring and fixed with screw 18,
The leaf spring 17 and the upper part of the clamp claw 7 are in contact with each other, and the lower end of the clamp claw 7 is pushed outward.

19 is a notch provided in the rotating body 14 so as to engage with a key, and 20 is an end plate that is fitted into both ends of the tension member A.
0 is provided with a notch 21 into which the rail b fits.

Note that the above-mentioned tensile material A is made of a shaped material such as aluminum.

The locking device according to this invention has the above configuration, and
Next, to explain how to use it, as shown in Fig. 4, fit the bottom opening of the strut material A into the rails b and b of the double-sliding window C5C, and insert the above strut material into the vertical stile of window frame B (7). Bring one end of material A into contact.

Next, by inserting a key into the notch 19 of the rotating body 14 and rotating the rotating body 14 approximately 90 degrees, the upper ends of the clamp claws 7, 7 are pushed apart by the cam 15 that rotates together.

Therefore, the rail b can be clamped by the clamp claws 7, 7, and the tension member A can be fixed to the rail b.

When the window C9C is opened in this state, the vertical stile of the window C comes into contact with the other end of the strut member A, preventing the window C from being opened in a constant manner.

When fully opening the window C, by rotating the rotating body 14 with the key and releasing the upper ends of the clamp claws 7, 7, the lower ends of the clamp claws 7.7 are released from the rail b, and the protrusion is released. Material A can be removed.

Furthermore, when the windows are open, the two windows on both sides may be closed using chains or metal fittings, and the above-described tension material A may be used for the two windows in the center.

As shown in E, according to the window locking device of this invention, one end directly or indirectly contacts the vertical stile of the window frame, and the other end contacts the window that is open to the extent that no one can enter or exit. Since a length of tension material is provided and the tension material is fitted into the rail, the window cannot be opened until people can enter and exit, and in particular, it is impossible to open the window directly to the stile of the window frame or to the door. Since one end of the tension member is in contact with the tension member, the tension member does not move even if an impact is applied to the tension member in the axial direction, and it has an excellent effect as a flange of a window.

In addition, since the tension member has a built-in retaining device that engages with the rail when rotated by a key, the tension member is prevented from coming off from the rail, which is highly effective in preventing crime.
