JP2024147450A - Locking system for windows to prevent children from falling out - Google Patents

Abstract

To reliably lock a half-open window or the like.
[Solution] A latch or a similar device that can insert and remove a protrusion is attached to the mating frame of the inner door at a location corresponding to the top or bottom frame of the outer door, with its protrusion facing the top or bottom frame, and a hole through which the protrusion can be inserted and removed is made at any point on the top or bottom frame that corresponds to this protrusion.
[Selection diagram] None

Description

The present invention is concerned with preventing small children from opening half-open windows and falling out, as well as preventing burglars from breaking in.

There are many products on the market, such as "window locks," that are used as auxiliary locks for half-open windows, but these devices are not secure and are not guaranteed to be secure, as stated in the product labels, which state that they are "not an absolute security device."

As a solution to this problem, there are cases where a fixture is installed between the inner and outer doors, but this requires a large gap between the two doors, which creates the risk of drafts.

And while they cannot be easily opened, they cannot be prevented from being closed.

There are frequent reports of small children opening half-open windows and falling out because they cannot be locked securely, or of burglars breaking in.

We also occasionally hear stories of young children locking the door and locking people out on the balcony while they are hanging out laundry.

The aim of the present invention is to ensure that these unforeseen circumstances are prevented.

Just connect and secure the inner door to the outer door.

To achieve this, latches and holes are provided on both the inner and outer doors so that the two doors can be connected and fixed together.

The present invention ensures that half-open windows and other windows are securely fixed in that position.

By freely choosing the position of the holes, the door opening degree can be freely and securely fixed.

When this invention is installed on the upper frame, it becomes more difficult for small children to reach, so it is more effective at preventing accidents where children open it and get out and fall.

If you use a strong latch that can be locked with a key, people will be unable to get in or out simply by destroying part of the glass and removing the crescent lock, which is also very effective in keeping thieves away.

You can safely enjoy the comfortable breeze through the screen doors.

The inner and outer doors are securely locked, which prevents small children from locking the door and locking themselves out on the balcony, for example, when hanging out laundry on the balcony.

A latch or a similar device with a protrusion that can be inserted and removed (hereafter referred to as "latch, etc.") is attached to the inner door joint frame at a location that corresponds to the top or bottom frame of the outer door, with its protrusion facing the top or bottom frame, and a hole is made at any point on the top or bottom frame that corresponds to this protrusion so that the protrusion can be inserted and removed.

When using a hinge as a latch, etc., it can be used by attaching a protrusion such as a bolt to the side that corresponds to the hinge hole.

A hinge has two holes, one for a bolt and the other for a wing bolt, and two corresponding holes are drilled in the receiving part. A recessed nut is attached to the hole that corresponds to the wing bolt, making it more convenient to use a simple bolt normally and tighten it with the wing bolt when more rigidity is required.

Claims (3)

For sliding doors such as aluminum sashes, a latch or similar device with a protrusion that can be inserted and removed (hereafter referred to as "latch, etc.") is attached to the inner door joint frame at a location that corresponds to the upper or lower frame of the outer door, with the protrusion facing the upper or lower frame, and a hole is provided at any point on the upper or lower frame that corresponds to this protrusion so that the protrusion can be inserted and removed. The hole of claim 1 is provided in a position where, when a latch or other projection is inserted and the door is fixed in its open position, only a slight breeze can get in and out, only small animals such as kittens can get in and out, and adults cannot get in and out, etc., and stickers with letters or pictures such as wind, kitten, thief, etc. are placed near the hole, or these pictures are painted on the upper or lower frame. A system in which the system of claim 1 is installed with the inner door and the outer door swapped.
