Description

[Detailed Description of the Invention] The present invention relates to a surface lattice for a balcony which is bisected and can be opened and closed on one side to allow free entry and exit, and is further equipped with an automatic lock.

In the past, people often forgot to lock their balcony windows when they went out, or went downstairs with the windows open, or went to bed with only insect-proof nets in the summer. , was very careless.

Therefore, in the present invention, even in the above-mentioned cases, the grid is constructed so that it can be easily opened and closed with a single knob, is automatically locked when closed, and cannot be opened from the outside.

To explain with drawings, in the front view of Fig. 1, 1 is a fixed lattice part, 2 is an opening/closing lattice part, 3 is an upper rail made of vertically rectangular material, and 3' is a lower part. 4 is an upper corner fixing part of the fixed lattice part, 4' is a lower corner fixing part, and both corner fixing parts 4, 4' are attached to an end frame 5 which extends further up and down from the lattice part. A flat plate material is bent and welded to the upper and lower ends, and a rectangular pipe-shaped upper rail connection is located above the end frame 5 and slightly in the middle of the lower corner fixing parts 4 and 4'. The attaching portion 6 and the lower rail connecting portion 6' are welded via the intervening pieces 7, 7', and the upper and lower rails 3, 3' are attached to the upper and lower rail connecting portions 6, 6'. It is a removable assembly type, and an upper rail fixing part 8 and a lower rail fixing part 8' are bent at the ends of the upper and lower rails 3, 3'.

Further, 9 is an upper center fixing part, and 9' is a lower center fixing part.

Further, 10 and 10' are upper rail insertion rings bent into a rectangular shape and welded to the upper part of the opening/closing grid section 2, and 11 and 11' are lower rail insertion rings as well. Pulleys 13 and 13' are inserted into and held at the upper end of the axles 12 and 12', respectively.

In addition, in order to prevent the lock from being opened and closed from the outside, 14 and 14' are fine lattice parts that are made finely as shown in the figure, so that it is impossible to insert your arm into the lock. Further, reference numerals 15 and 15' designate finger insertion prevention plates located at the center of the lock for preventing fingers from being inserted into the lock, and examples of these plates are shown.

In addition, in the back view of Fig. 2, 16 is the opening/closing side case of the automatic lock, 17 is the fixed side case, and 18 is the knob, and the automatic lock is as shown in Fig. 3. In the gap created between the fixed lattice part 1 and the opening/closing lattice part 2 due to the intervening pieces 7, 7', the opening/closing side case 16 is placed in an appropriate position in the center of the central vertical frame 19 of the opening/closing lattice part 2, and Case 17
is placed at a suitable location in the center of the central vertical frame 20 of the fixed grid section 1,
They are fixed by fixing parts 21 and 21', respectively, and 22 is a lock protection cover provided on the fixed side case 17 to prevent the lock from being unlocked by tying it with a wire or the like.

4 and 5 are detailed views showing an example of an automatic locking part. Reference numeral 23 is a hook whose tip is curved in the shape of a question mark, a shaft insertion fixing hole 24 is provided in the center, and a shaft insertion fixing hole 24 is provided at the rear end. Spring 25
are attracted upward by connecting them.

Further, the shaft 26 inserted and fixed in the shaft insertion fixing hole 24 uses both side plates of the opening/closing side case 16 as bearing parts, and one end corner part is inserted into the knob 18 and fixed by screwing or with a pin or the like. .

On the other hand, the upper end of the vertical part of the L-shaped part formed in the fixed side case 17 has a shape that matches the inner surface of the curved part of the hook 23, and forms a circular part 27 at a position suitable for connection with the hook 23. .

Further, the case outer wall 28, in which the parallel portion of the L-shaped portion is fixed to the inner surface, is further extended to form the upper and lower lock protection covers 22, 22'.

Further, the lower half of the front surface of the curved part of the hook 23 slides against the circular part 27 and swings upward against the force of the attracting spring 25, and is further pushed to the circular part 2.
This is a hit to hold it at the appropriate height to fit into the 7.

Also, 30 is a double lock tightening part with knurling on the bolt head, 31 is a nut fixed to the bottom of the case by welding, etc., 32 is a spring to prevent loosening, and 33 is a ring to prevent it from coming off. It is.

Further, 34 is a handle provided at a suitable position inside the opening/closing lattice portion 2.

Since the present invention is constructed as described above, it is automatically locked by simply tightening the opening/closing lattice part 2 from the inside, and once locked, the fine lattice parts 14, 14', and Finger insertion prevention plate 1
5 and 15' make it impossible to open from the outside, and the lock protection covers 22 and 22' also prevent opening with a wire or the like.

Also, when going out, etc., use the double lock tightening part 3.
If you tighten it to 0, the hook will not come off even if there is a slight vibration, and the level of security will be even higher.

The automatic locking unit of the present invention also has the advantage of eliminating the need for a plug-in key that is easy to lose.

Although this invention is illustrated for a balcony window, when used for a balcony entrance etc., the lower rail should not be higher than the threshold and the upper rail should be lowered slightly, so the central upper fixing part 9 needs to be long. There is.
