Description

Tempered glass safety door with improved cost reduction and improved workability}

The present invention relates to a new concept technology that increases manufacturing convenience by manufacturing tempered glass safety doors using a simple assembly method, reduces manufacturing costs, and dramatically improves overall workability.

In general, tempered glass doors have a beautiful appearance and have the advantage of being able to check the situation outside the door and who enters the door even when closed, so they are used at entrances and exits of business places including restaurants, various business offices, exhibition halls, offices, hair salons, etc., and schools and kindergartens. It is widely used in various buildings such as educational institutions and government offices.

These tempered glass doors can be divided into a sliding door that opens and closes by sliding, or a hinged door that opens and closes by pushing and pulling. However, in both cases, if your hand, hem of clothing, or a bag or item being carried is caught during the entry and exit process, the door itself will be very damaged. Because it is made of hard glass, injuries or damage often occur.

Considering this reality, recently, tempered glass safety doors have been proposed as a way to solve the problems of safety accidents that occur during the entry and exit process of the above-mentioned doors.

In the conventional tempered glass safety door described above, vertical frames are installed on both sides of the tempered glass, horizontal frames installed on the top and bottom of the tempered glass are connected and installed between the vertical frames, and a separate safety door is installed at the tip of the vertical frame. As the bar is installed so that it can emerge, even if your hands, feet, hem of clothes, or various items being transported or carried are caught during the entry and exit process of the tempered glass safety door, you will not be injured or damaged, thereby providing a useful effect that can maximize safety and reliability. to provide.

A representative prior art related to such a tempered glass safety door is “Patent Registration No. 1144650, Title/Tempered Glass Safety Door with Improved Insulation”.

In the prior art, the horizontal frame and vertical frame that form the framework of the tempered glass safety door demonstrate their own thermal insulation performance, thereby increasing the indoor insulation effect and saving energy.

In the prior art, in order to assemble the horizontal frames horizontally on top and bottom of the vertical frame, the side parts 2 on both sides are installed so that the horizontal frames 3 are fitted on the top and bottom of the side parts 2 of the vertical reinforcement frame 1, as shown in FIG. 10. A process of cutting and processing to form the fitting portion 4 is essential, making it difficult to manufacture a tempered glass safety door and increasing costs.

In addition, the vertical reinforcement frame 1 is made of aluminum and is made of an expensive and bulky single piece, which causes the problem of increased manufacturing costs and worsening profitability.

The present invention is a means of solving the above-described problem by assembling a pair of horizontal frames directly on the upper and lower sides of the main reinforcement frame, and then installing a plurality of sub-reinforcement frames at an upper and lower distance between the pair of horizontal frames. A technology is being sought to assemble the side parts of the reinforcement frame integrally and to assemble the exterior frame so that the front and rear parts of the main reinforcement frame and sub reinforcement frame are surrounded.

In addition, the present invention seeks a technology that allows the inward locking protrusions protruding at the front and rear ends of the sub-reinforcement frame to be integrated and assembled with a pair of outward locking protrusions protruding before and after the side surfaces of the main reinforcing frame. .

According to the present invention, the production of a tempered glass safety door is simple and easy by assembling the horizontal frame directly on the top and bottom of one side of the main reinforcement frame, thereby omitting the cutting process for assembling the horizontal frame to the existing vertical reinforcement frame. , provides the effect of significantly reducing costs.

In addition, the exterior frame is assembled to surround the front and rear parts of the main reinforcement frame and a plurality of sub reinforcement frames assembled at upper and lower intervals in the upper and lower sections of the main reinforcement frame, excluding the space where the pair of horizontal frames are assembled, thereby forming the exterior of the vertical frame. Not only is this beautiful, but it also sufficiently performs the role of a reinforcement frame, and reduces the material of the sub-reinforcement frame by the amount of space formed between the sub-reinforcement frames, thereby significantly reducing production costs and improving profitability.

A preferred embodiment will be described to implement in more detail the means of solving the problem to be solved by the present invention.

Looking at the overall configuration according to a preferred embodiment of the present invention schematically based on the attached drawings, a pair of main reinforcement frames 10, a pair of horizontal frames 20, a plurality of sub reinforcement frames 30, a pair It can be confirmed that it is largely divided into components of the exterior frame 40.

Hereinafter, the present invention comprised of the above schematic configuration will be described in more detail for ease of implementation.

First of all, the present invention is to improve the absurdity that separate cutting processing was required to assemble the horizontal frame (3) as the conventional vertical reinforcement frame (1) was formed as a single piece, and the vertical reinforcement frame (1) was formed as a main reinforcement frame ( 10) and a plurality of sub-reinforcement frames 30. The technical point is that it consists of an assembled configuration.

For this purpose, a pair of main reinforcement frames 10 are formed with front and rear parts 12 and 13 at right angles to the front and rear ends of the facing side parts 11, respectively, and the front and rear parts 12 and 13 are formed at right angles to each other. A safety bar guide 14 is formed at the tip, which serves to guide the safety bar to move left and right so that it can freely emerge and descend, and a safety bar emergence path 15 is formed between the safety bar guides 14.

In addition, a leaf spring is installed between the safety bar 5 and the side portion 11, so that the safety bar 5 can be raised and lowered by the elasticity of the leaf spring.

A pair of horizontal frames 20 are directly butted and assembled on the upper and lower sides of the side portion 11 of the pair of main reinforcement frames 10, so separate cutting processing is not necessary, and in the state of being butted to the side portion 11, The piece 21 penetrates the side portion 11 and is screwed through the piece coupling portion 22 formed along the longitudinal direction inside the horizontal frame 20, so that the main reinforcement frame 10 and the horizontal frame 20 are It is possible to maintain strong mutual integrity.

The main reinforcement frame (10) of the present invention is assembled by directly butting the horizontal frame (20) without separate cutting processing, so that the left and right width is about half that of the conventional vertical reinforcement frame (1), thereby performing the function of a vertical frame. Considering that this cannot be done, a plurality of sub reinforcement frames 30 are provided that are integrally assembled with the main reinforcement frame 10.

The plurality of sub-reinforcement frames 30 are integrally assembled on the side portion 11 of the main reinforcement frame 10 with an upper and lower gap between a pair of horizontal frames 20, and the main reinforcement frame assembled as an integral part in this way (10) and the sub-reinforcement frame 30 can maintain the same width as the conventional vertical reinforcement frame (1), as shown in FIG.
