Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an auxiliary lock that locks a glass door that is in a half-opened state for passing through a pipe of a room air conditioner by using an existing crescent. .

<Prior Art> When pulling out a room air conditioner pipe outdoors using a window without making a hole in a wall, a glass door is opened halfway and a window panel is fitted into the gap. The half-opened glass door is usually locked by an auxiliary lock using the existing crescent. As the auxiliary lock, a plate-type locking metal fitting or a wire-type locking metal fitting was once used, but nowadays, it is almost unified into a lock type that is screwed to a window frame.

The plate-type locking metal fittings used in the past are attached to the glass plate of the glass door, and the rotating portion of the crescent and the crescent hook combined with the crescent are engaged with each other at both ends thereof. Further, the wire-type locking metal fitting is one in which a wire made of a twisted metal wire is hung on a crescent hook, a fixing tool for fixing the wire is attached to a plate glass, and the rotating part of the crescent is engaged with the fixing tool. Is.

<Problems to be solved by the invention> Both plate-type locking fittings and wire-type locking fittings can be easily attached to the glass door without damaging the window frame. Nonetheless, the reason why these locking fittings were not used frequently is that the former was unable to adjust the opening amount of the glass door, and the latter was the case where the wire was hung on the crescent hook. The reason is that it is difficult to work, or caulking is required to fix the wire to the fixture.

For this reason, locks that are screwed to the window frame are now widely used, but since the window frame requires drilling, the workability is not good, and above all Also has the drawback of damaging the window frame. Further, if the mounting position is incorrect, there is the inconvenience that the correction is difficult and the hole must be re-drilled.

The present invention has been devised in view of the above circumstances, and provides a locking metal fitting that can be easily attached to a glass door without damaging the window frame, and that the opening amount of the glass door can be adjusted and reattached very easily. With the goal.

<Means for Solving the Problem> A locking metal fitting according to the present invention is a locking metal fitting that locks a sliding glass door locked by a crescent in a half-open state, and is bent in parallel at intervals. And a hook wire made of a metal wire, one end of which is adapted to be engaged with a crescent hook to be combined with a crescent, and the hook wire is fixed and bonded to a glass plate of a glass door to which the crescent hook is attached. A pair of plate-shaped members made of a metal plate that is harder than a metal wire that constitutes the hook wire, the fixture having a hook portion that engages with the rotating portion of the crescent at one end, It is characterized in that the parallel portions of the hook wire are sandwiched and screwed to each other so as to be able to bite into the parallel portions of the hook wire and fix the parallel portions. It

<Operation> Hang one end of the hook wire on the crescent hook, fix the hook wire to the fixture with the rotating part of the crescent engaged with the hook part of the fixture, and attach the fixture to the glass plate of the glass door. wear. Then, the two glass doors are locked by hooking the rotating part of the crescent on the hook part of the fixture attached to the plate glass. When hooking one end of the hook wire on the crescent hook, the hook wire is made of a rigid metal wire, so that the one end can be easily hooked on the crescent hook.
In addition, the fixture is not only easy to fix the hook wire by screwing, but it is made of a metal plate that is harder than the hook wire so that it can be caught in the hook wire by screwing. The hook wire is firmly fixed to the fixture. Therefore, even when a large force in the opening direction is applied to the two locked glass doors, the movement of the glass doors is prevented.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 1 is an exploded perspective view showing an example of a locking fitting according to the present invention, and FIG. 2 is a front view showing its usage state.

The locking metal fitting is composed of a hook wire 10 and a fixture 20 for fixing the hook wire 10, and is used to lock the sliding glass doors 30, 30 in a half-opened state. Glass door

The hook wire 10 of the locking metal member is made of an aluminum wire having an outer diameter of 2 to 3 mm, and one end thereof is bent in parallel with a space for engaging the crescent hook 50. A resin chip 11 is attached to the other end of the hook wire 10. The length of the hook wire 10 is in the locked state glass door 3
It is made sufficiently larger than the half-opening amount of 0,30.

The fixture 20 for fixing the hook wire 10 is the mounting base 21.
And a pressing plate 25 that covers the mounting base 21,
Both are plate-shaped members obtained by pressing a stainless steel plate having a thickness of 0.8 to 2 mm. The mounting base 21 has two screw holes 22 and 22, and a rotating portion 41 of the crescent 40 is provided at one end.
Is formed with a hook portion 23. Screw holes 22,22
The circumference of the bulge is trapezoidal toward the surface. Mounting base 21
Double-sided adhesive tape, one side of which is protected by release paper on the back side of
24 is pasted.

The pressing plate 25 has round holes 26, 26, and is fixed to the mounting base 21 by screwing screws 28, 28 into the screw holes 22, 22 of the mounting base 21 through the round holes 26, 26. Both ends of the pressing plate 25 are bent to the back side at a substantially right angle, and substantially V-shaped notches 27, 27 into which the parallel parts of the hook wire 10 are fitted are provided at the bent parts. . Since the pressing plate 25 is harder than the hook wire 21, the notches 27, 27 cut into the parallel portion of the hook wire 10 as the pressing plate 25 is screwed to the mounting base 21.

The locking metal fitting with the above configuration is a
Is used to lock this.

With the parallel portions of the hook wire 10 fitted in the notches 27, 27 of the pressing plate 25, the pressing plate 25 is overlaid on the mounting base 21, and the mounting base 21 is passed through the round holes 26, 26 of the pressing plate 25.
Lightly screw the screws 28, 28 into the screw holes 22, 22, to temporarily assemble the locking metal fittings. In this state, insert the hook wire 10 into the gap between the glass doors 30 and 30 and hang the crescent hook 50 at one end.
After that, the fixture 20 is slid with respect to the hook wire 10 to a position where the rotating portion 41 of the crescent 40 engages with the hook portion 23 of the mounting base 21. If the rotating portion 41 of the crescent 40 is difficult to engage with the hook portion 23 of the mounting base 21,
Adjust the height of the hook portion 23 with pliers or the like.

When the position of the fixture 20 is determined in this way, the screws 28, 28
Screw in strongly. As a result, the pressing plate 25 is fixed to the base 21, and the notches 27, 27 of the pressing plate 25 bite into the parallel portion of the hook wire 10 along with the fixing, and the hook wire 10 is fixed to the pressing plate 25. It Then, the locking metal fittings are once removed from the glass doors 30, 30, the release paper is peeled off from the double-sided adhesive tape 24 attached to the back surface of the mounting base 21, and one end of the hook wire 10 is hooked on the crescent hook 50 again. Then, the fixture 20 is pressed against the plate glass of the glass door 30 to which the crescent hook 50 is attached and fixed by adhesion.
If the fixture 20 does not adhere to the glass plate of the glass door 30,
Adjust the bending angle of the hook wire 10. An aluminum sheet 29 is attached to the fixing portion of the fixture 20 from the outdoor side to prevent deterioration of the double-sided adhesive tape 24 due to solar heat and ultraviolet rays.

As described above, by engaging the rotating portion 41 of the crescent 40 with the hook portion 23 of the locking fitting attached to the glass plate of the glass door 30, the glass doors 30, 30 are locked in the half-opened state. When the outside in the opening direction is added to the glass doors 30,30, the fixture tends to be separated from one end of the hook wire 10, but the notches 27,27 of the pressing plate 25 cut into the parallel portion of the hook wire 10. Therefore, the fixture 20 does not move. Therefore, there is no possibility that the glass doors 30, 30 will open carelessly.

In addition, when attaching to the glass door 30,
It is not necessary to process the frame body 31 of the
