Description

Crime Prevention Grille for Window}

(Technology)

The present invention relates to a security grate installed on a window to prevent external intrusion, and more specifically, to fit the size of the window to the size of the window against the variation in the size of the window that may occur during the construction of the standardized window. It is about a crime prevention grate that can be changed within a certain range so that mass production can be supplied.

(Background)

Security gratings are widely applied to windows to prevent outsiders from invading, and are manufactured and used in a wide variety of materials and structures depending on the location, size, and user's taste.

Security grate is a series of processes in which a contractor visits a construction site to measure the size of a window (window) on which the grate is to be installed, creates a grate at the workplace based on the measured value, and then moves the grate to the construction site and attaches it to the window. It is common to order the construction by a professional contractor, such a conventional security grate has some inconvenience and cost increase factors in the construction process.

Specifically, the size of the windows that are applied to buildings such as houses is generally standardized to 1200MM × 450MM, 1200MM × 1200MM, 1200MM × 2400MM, etc. Due to the size deviation, the thickness variation of the mortar applied to the circumference of the window frame, and the width variation of the mortar covering the window frame, it is practical to manufacture security screens based on the standardized window size without measuring the size of the final installed window. There are many difficulties.

For this reason, the contractor must visit the construction site at least twice for the size measurement and construction, and even if the size of the window cannot be adjusted due to various factors even if the size of the window is measured, a lot of work is needed to adjust the size of the window. You are spending time. Given that labor costs are a big part of the cost of installation of crime prevention grate, this increase in work time is a factor in the rise of product prices.

In addition, since the security grate cannot be perfectly standardized in size, it is practically difficult for the contractor to mass-produce the security grate according to the standardized window standard, and the consumer does not customize the security grate to the professional contractor. It is not possible to purchase a standardized product and install it on a window by itself, and thus do not enjoy the benefits of mass production and the purchase of ready-made products.

Therefore, considering that the windows of the building are widely standardized and the size of the window to adjust the size of the security screen made without actually measuring the window is a small range within a few tens of millimeters, the security screen can be controlled within a certain range. It will be useful in many ways.

The purpose of the present invention is to solve the problem of the conventional crime prevention grate that could not be adjusted at all, as described above, by changing the width and length of the crime prevention grate in a certain length range, without measuring the window size It is to be able to manufacture and construct crime prevention grate.

The purpose of the present invention is to provide a prefabricated security screen that is adjustable in size, to save construction time, to enable mass production, and to allow consumers to construct the security screen directly through the purchase of ready-made products.
