Description

[Detailed Description of the Invention] This invention relates to a temporary locking device for a screen door that can be rolled up or folded and installed in an opening of a house.

Conventionally, when installing this type of screen door, there was a height error between the receiving frame attached to the opening frame and the locking hook of the temporary lock that locks the screen door, making it difficult to install it in the correct position. It has the disadvantage of being troublesome. Moreover, it becomes difficult to fulfill the role of a temporary lock due to errors caused by misalignment of the housing during use. In this case, the repair work becomes extremely troublesome.

This invention has been improved in view of the above-mentioned drawbacks, and its characteristic structure is that an engaging fitting having a latching protrusion is attached to a receiving frame attached to one end of the opening. An unlocking knob is attached to the vertical stile from the front and back using a connecting shaft, and a vertically elongated hole is bored through which the connecting shaft slides up and down. Moreover, an engaging protrusion provided with a curved hook portion that engages with and disengages from the latching protrusion is integrally fixed to the unlocking knob. Furthermore, a set screw inserted from the pull seat plate and a nut provided in a vertical groove in the vertical stile are screwed together so that they can be tightened and loosened at will. Therefore, according to this idea,
Even if there is a difference in height between the receiving frame of the opening and the unlocking knob on the screen door side, the unlocking knob and the engaging protrusion can be easily raised and lowered to adjust the temporary lock, making it easy to stand up. It has an effect that is easy to achieve. In addition, the unlock knob is
It can be unlocked and temporarily locked with a single touch, making opening and closing operations extremely easy.

Next, an embodiment of this invention will be explained with reference to the drawings.A screen door 1 installed in an opening of a house is rolled up or folded, and a vertical stile 2 at the opening/closing edge of the screen door 1 is attached to one end of the opening. It is fitted into the attached receiving frame 3. The vertical stile 2 has a locking knob 4 from the front and back.
4 are fixed together through the interposition of a connecting shaft 5, and a vertically elongated hole 6 is bored through which the connecting shaft 5 slides up and down. Further, the receiving frame 3 is equipped with an engaging metal fitting 8 having a latching protrusion 7 on its inner bottom. Next, an engaging protrusion 9 provided with a curved hook portion 10 that engages and disengages with the locking protrusion 7 is integrally fixed to the unlocking knobs 4, 4, and a restoring spring 11 is wound around it. be. A vertically elongated handle 16 is integrally formed on the seat plate 12 of the unlocking knob 4, and the seat plate 12
A set screw 13 inserted from the surface of the frame 2 and a nut 15 housed in a vertical groove 14 in the vertical stile 2 are screwed together so as to be tightenable and loose.

This device has the above-mentioned configuration, and to explain its function now, the screen door 1 is attached to the opening in advance.
By moving the unlocking knobs 4, 4, the screen door can be rolled up by itself or opened by pulling the handle 16. On the contrary, when closing, when the vertical stile 2 is pressed against the receiving frame 3 by holding the handle 16, the engaging protrusion 9 is engaged with the engaging fitting 8 against the spring 11, thereby closing. Next, when installing the screen door 1 or constantly using it, if the engagement protrusion 9 and the engagement fitting 8 do not engage or disengage due to a difference in height, the seat plate 12
Loosen the locking screw 13 and remove the unlocking knob 4 and connecting shaft 5.
After moving and adjusting both to the desired position, remove the set screw 1.
All you need to do is tighten 3.

As described above, according to this invention, the screen door can be opened by a slight movement of the unlocking knob, and can be temporarily locked by simply pulling the handle, making the opening/closing operation extremely simple. Since it is extremely simple, there is no failure and it can be provided at low cost. In addition, the vertical stile has a lock opening knob that is fixed integrally from the front and back through a connecting shaft, and a vertically long hole that allows the connecting shaft to slide up and down. This has the effect of allowing the unlocking knob to move up and down by a distance of . In addition, the engagement protrusion fixed to the unlocking knob and the winding of the restoring spring make locking/unlocking easy and reliable, and the locking screw inserted from the seat plate and the locking screw inside the vertical stile Due to the nut provided in the vertical groove, the lifting and lowering adjustment of the unlocking knob can be easily tightened and loosened by operating the set screw from the surface, which is very convenient.
