Description

[Detailed description of the invention] This invention mainly relates to the improvement of locking devices for sliding windows, sliding doors, etc. It can be easily installed by sharing one type of lock even on short windows or doors with different width dimensions. The purpose is to

Conventionally, there is a locking device in which a lock with a hook that can be moved up and down is attached to the short frame of an aluminum window frame, and a receiver that engages and disengages from the hook is attached to the short frame side of the fittings frame. Since the width of the short frame of the window frame varies depending on the type and size of the window, it is necessary to prepare several types of locks that correspond to the width of the bag frame. There was a cost issue.

In order to solve this problem, we have prepared several types of hooks, which are internal members of the lock, to correspond to the width dimension of the window frame, and when installing on-site, you can change the lock to the width dimension by replacing only the hook. There are hooks that are made to correspond to different window short frames, but this also requires the manufacture of several types of hooks, and the need to select and assemble them during on-site construction. This results in loss of the parts, reduced work efficiency, and increased costs.

This invention improves the above-mentioned drawbacks of the conventional method, and there is no need to replace any internal parts such as the hook of the lock, and the entire lock can be applied as it is to all short window frames of various widths, simplifying on-site construction. The aim is to provide a locking device for windows, etc. that can reduce component costs, and its features are a receiver attached to the short frame of the fittings and a locking device that can be moved up and down on the frame of the sliding window or sliding door. In a locking device such as a window, which has a hook operating rod attached thereto, and a hook that is provided on the hook operating rod and is removable from the receiver by vertical movement of the hook operating rod, the hook is located at the tip of a hook-shaped portion. By colliding with the receiver on the edge, a slope is formed for downward movement with the hook operating rod, and one of the hook and the hook operating rod is fixed to adjust the position of the hook in the direction of movement of the jamb. The main feature is that a plurality of holes for screws are formed in a row.

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

Figure 1 shows a front view of the indoor side of the short frame part of a sliding window to which this invented device is applied. This is a lock attached to the

The lock 3 shown here is a lock with a handle, and as shown in FIG. 10, a vertical cross-sectional view, and FIG. It consists of a vertically elongated lock body 6 in which the lower half portions 5 are formed, a hook operating rod 7 that is vertically movably mounted on the back side of the hook mounting portion 5, and a hook 8 that is attached to the operating rod 7. .

The entire hook operating rod 7 is formed in the shape of a vertically long strip, and a concave finger hook 9 provided at its upper end is inserted through an insertion hole 10 opened at the lower end of the handle 4 so as to protrude into the handle 4. At the same time, the vertical hole 11 opened at the lower end is inserted into the hook attachment part 5.
It is slidably fitted into a boss 12 protruding from the rear surface of the lower end.

Therefore, this hook operating rod 7 is guided by the insertion hole 10 and boss 12 and slides up and down by lifting and lowering it in the direction of arrow A in FIG. A plastic plate-shaped front retaining ring 13 is fitted into the boss 12, and this ring 13 pushes the edge 14 of the vertically long hole 11 of the operating rod 7 toward the lock body 6 through a spring bias. Since it is always strongly pressed, the operating rod 7 is set so that it will not fall due to its own weight even if it is pulled upward.

A spring that biases the presser ring 13 is indicated by reference numeral 15 in the figure.

Further, a hook mount 16 is protruded from a longitudinally midway point on the back side of the hook operating rod 7, and the hook 8 is detachably attached to the mount 16.

The hook 8 is formed in a front-facing shape, and includes a base portion 18 having a mounting hole 17, and a hook-shaped portion 19 connected at a substantially right angle to the tip of the base portion.
The fixing screw 20 is attached to the mounting base 16 so that the piece-shaped part 19 at the tip thereof protrudes upward to one side of the lock body 6.
It is attached removably.

In addition, this hook 8 has a plurality of mounting holes 17 formed in a continuous manner in the lateral direction as shown in the seventh figure so that the amount of lateral protrusion (m = lateral) of the lock body 6 can be variably adjusted in several stages. .

In this case, it is conceivable that the mounting holes 17 be formed in a horizontally long hole shape, such as by making a plurality of the mounting holes 17 independent from each other and arranging them in the horizontal direction as shown in the 8th figure, or in the shape of a horizontally long hole as shown in the 9th drawing. If a plurality of holes 17 are independent, the distance between the holes becomes wide and fine position adjustment is not possible, and if they are long holes, they may shift when they collide with the receiver 38. The polymerized one shown in Figure 7 is the best.

The hook 8 is mounted on the hook mount 16 along a rotation prevention wall 21 protruding from the match 16, thereby providing a reliable means for preventing rotation around the locking screw 20.

Therefore, the lock 3 having the above structure is attached to the indoor front wall 2 of the window short frame 2.
A pair of upper and lower mounting screws 24 are installed in the vertical opening 23 opened in 2.
During this installation, as shown in FIGS. 2 and 3, the overall shape of the lock main body 6 of the lock 3 is approximately the same, and the handle part 4 of the lock main body 6 and the lock Bosses 25 protruding from the upper and lower ends of the back surface of the main body 6.
A pull tool 29 (not including the hook 8 and the hook operating rod 7) having a pull portion 26 and bosses 27 and 28 symmetrically with 12 is also used.

That is, the lock 3 is attached to the vertical opening 2 of the front wall 22 of the window short frame 2.
3, the flange 30 around the entire circumference of the lock body 6 is the vertically elongated opening 2.
3, and the hook 8 is fitted so that the hook-shaped portion 19 at the tip thereof protrudes an appropriate amount outward from the opening 33 formed in the side wall 32 of the bag frame, and the other puller 29 is
This entire periphery flange 34 is connected to the outdoor rear wall 35 of the window short frame 2.
After fitting into the opening 36 so as to engage the edge 37 of the vertical opening 36 which is opened at a position symmetrical to the vertical opening 23, the tips of the upper and lower mounting screws 24 are inserted from the front side of the lock 3. The lock 3 is embedded in the front wall 22 by passing through the bosses 25, 12 and screwing into the respective threaded holes of the bosses 27, 28 on the pull member 29 side.

FIG. 5 shows a front view of a receiver 38 used in pair with the lock 3, which includes a mounting board 39 and a hook receiver 40 protruding from the front side of the board 39. The hook receiving part 40 has a narrow tip and a downwardly open recess 41 at the bottom of the tip.

As shown in FIGS. 2 and 4, this holder 38 is attached to the bag frame 4 of the fittings frame into which the window is fitted.
5, the lock 3 is mounted on the window short frame 2 with a mounting bolt 42 so as to correspond to the position of the hook 8 of the lock 3.

Note that a slope 43 is formed on one side edge of the hook-shaped portion 19 of the hook 8, and the slope 43 is formed on the hook receiving portion 40 of the other receiver 38.
A sloped surface 44 is formed parallel to and facing the surface.

In the locking device constituted by the lock 3 and the receiver 38, the finger is hooked onto the finger hook 9 of the hook operating lever 7 of the lock 3, and the operating lever 7 is moved from the raised position shown by the imaginary line B in FIG. Solid line C
Once the window has been lowered to the lowered position shown in Fig. 2, put your hand on the handle part 4 and pull the window in the direction of the arrow in Fig. 2 so that the window short frame 2 comes close to the fitting form 45. When the hook receiver 40 of the receiver 38 is completely closed to the position where it hits the stopper member (not shown) attached to the frame 45 side, the hook receiver 40 of the receiver 38 is aligned with the imaginary line E in FIG.
As shown in , the hook 8 enters into the opening 33 of the window short frame 2 and is positioned directly above the hook-shaped portion 19 of the hook 8 inside the opening 33 .

Furthermore, even if the window is strongly closed with the hook operating rod 7 raised, the slope 43 of the hook-shaped portion 19 of the hook 8 will hit the slope 44 of the receiver 38, and this impact will cause the hook 8 to It slides downward on the slope 44 of the tool 38 and descends together with the hook operating rod 7, so that the hook-shaped portion 19 of the hook 8 is located below the hook receiving portion 40 in the same manner as described above.

When the hook operating rod 7 is pushed up in the direction of arrow F in FIG. A locked state in which the hook receiving portion 40 is engaged is obtained.

This locked state is maintained by the strong pressing force of the presser ring 13 to prevent the hook operating rod 7 from lowering due to its own weight.

To release the locked state, hook your finger on the finger hook 9 and pull the hook operating rod 7 downward, and the hook 8 will be disengaged from the receiver 38, allowing you to open the window. It can be done.

By raising and lowering the hook 8 of the lock 3 on the side of the window short frame 2 in this way, the hook 8 can be engaged and disengaged from the receiver 38 on the side of the fittings formwork 45. Correct engagement of the hook 8 is conditioned on the hook 8 being installed in a correct position relative to the receiver 38 when the window is closed.

However, the width H of the window short frame 2 differs depending on the type and size of the window, and for this reason, conventionally, as mentioned above, hooks of various sizes corresponding to the width H of the window short frame 2 have been installed on site. Since the exact mounting position for the receiver 38 was determined by replacing the hook that matched the width of the short window frame 2 on-site, it not only made the replacement work troublesome, but also caused the problem of replacing the hook that matched the width of the window frame 2. This work was extremely inconvenient because the lock 3 was always equipped with a hook 8, but since a plurality of mounting holes 17 were provided in a row in the horizontal direction, it was easy to carry out on-site work. Even if the width dimension H of the short window frame 2 to which the lock 3 is to be installed is different, the fixing screw 20 can be selectively fitted into the mounting hole 17 of the hook 8 and fixed to the hook mounting base 16. By attaching the hook 8 to the width dimension H of the window short frame 2, the position of the hook 8 can be adjusted in the lateral direction toward and away from the receiver 38, which is easier than selecting and replacing a hook with a different dimension. The work is extremely simple and convenient.

Instead of the position adjusting means for the hook 8, the hook 8 is provided with a single mounting hole 17 through which the set screw 20 is passed, and the hook mount 16 is provided with a plurality of threaded holes 46 for screwing the set screw 20.
The hook operating rod 7 to which the hooks 8, which may be arranged in rows in the horizontal direction, is attached has a structure in which the finger hook 9 at the upper end is inserted into the insertion hole 10 at the lower end of the handle part 4, as in the above embodiment. 12 to 14 instead of
It may also be something that shows the other side of the figure.

The hook operating rod 7 shown in the figure has a finger catch part 9 in the middle part in the vertical direction, and the twenty finger catch part 9 faces the opening 47 opened in the hook mounting part 5 of the lock body 6. Further, a vertically elongated hole 48 is provided at the upper end, and this elongated hole 48 is slidably fitted into a guide pin 49 protruding from the back side of the hook mounting portion 5, and a spring stopper fitted onto the pin 49 is inserted into the elongated hole 48. The upper end of the hook operating rod 7 is held down by a ring 50, and the other hook mounting base 16 and the vertically elongated hole 11 at the lower end that fits into the boss 12 are similar to the hook operating rod 7 of the above embodiment. It is preparation.

In this embodiment, the hook operation lever 7 is lowered by hooking a finger on the finger hook 9 facing the opening 47 of the lock body 6.

In addition to the sliding window of the above embodiment, the locking device of this invention also has the following features:
It can be similarly applied to entrance doors, furniture doors, etc.

According to the present invention described in detail above, the hook 8 collides with the receiver 38 at the tip edge of the hook-shaped portion 19, thereby forming the slope 43 for moving F along with the hook operating rod 7, and 8 and one of the hook operating rods 7 has a plurality of consecutive holes for fixing screws 20 formed in order to adjust the position of the hook 8 in the moving direction of the car frame 2, so the car frame 2 can be pulled vigorously to tighten it. Even if the hook 8 collides with the receiver 38 and moves F and escapes, the hook 8, the receiver 38, and the hook operating rod 7 will not be damaged, and by adjusting the position of the hook 8, One lock 3 can be used in common for all sliding windows or doors with different width dimensions, and since the holes for the fixing screws 20 are formed in a continuous manner, they are finer than in the case of multiple independent locks. The position can be adjusted and it can be fixed more firmly than with a long hole.
