Abstract

The present invention relates to a protection cover for a fire door cylinder having a function of closing an upper part and a lower part which are open. A conventional protection cover could not prevent flames from permeating to be spread into a fire door since an upper part and a lower part thereof are formed in an open state. In order to close the upper part and the lower part of the conventional protection cover, an additional mold needs to be manufactured, and a company could not replace the mold easily because of expensive mold manufacturing costs. The present invention is to provide a protection cover for a fire door cylinder having a function of closing an upper part and a lower part which are open, which closes the upper part and the lower part using an upper cover and a lower cover fixed to the open upper part and the open lower part of the protection cover by a fixing unit so as to prevent flames and fire from being greatly spread by moving to the open upper part and the open lower part of the protection cover and then sticking on a heat insulation material after permeating into the cylinder through a gap between a door handle and the cylinder in case of fire.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a protective cover for a fire door cylinder having an open-

The present invention relates to a protective cover for a fire door cylinder having an open top and a bottom closing function, and more particularly, to a protective cover for a fire door, A fire door cylinder having an open top and bottom closing function for closing the upper and lower covers by means of upper and lower covers fixed by fixing means on the open top and bottom of the protective cover, The present invention relates to a protective cover.

Generally, a fire door is installed to prevent indoor or outdoor flames and firearms from spreading to other places when a fire occurs in a building.

Such a fire door is generally constructed by disposing a flameproof-resistant metal plate on both sides of the flame, finishing the open portion with another plate, and installing a thermal insulator therein to maintain the room temperature.

In addition, a hinge is provided on the rear surface of the door so that the door is rotatable, and the door is opened and closed using a door handle installed in the protective cover inside the door.

 Such a fire door is largely divided into a color door in which both side plates are formed thin and a variety of shapes, shapes and colors are applied on the outer surface, a colorful and luxurious aesthetic sense is sensed, and a general door in which a fire door is assembled and assembled .

As described above, the protective cover into which the cylinder is inserted can be easily installed inside the fire door by installing the cylinder of various shapes, sizes and widths on the protective cover designed according to the fire door standard, and in particular, The heat insulating material is formed by providing a mounting seat in advance in the form of a protective cover, so that a fire door can be manufactured quickly and dust or the like is prevented from being introduced into the cylinder.

[0004] As a prior art constructed to achieve the above-mentioned object, Patent Registration No. 1098880 (name: a key cylinder cover of a fire door) is disclosed. In terms of its construction, a cylinder having a locking protrusion And a cover having a hook which is inserted into a locking jaw of the bar with a guide groove interposed therebetween to prevent it from falling down on the guide groove and a reinforcing protrusion protruded to prevent warping on both sides.

Therefore, the cover provided with the cylinder and the cylinder bar provided on the front face of the fire door are fixed without being welded, thereby providing convenience of work.

However, in the conventional cover, the upper and lower portions are opened. In order to engage the cover and the cylinder bar, the guide groove is formed as a long slot through which the flame can move so as to provide a gap through which the flame can move, .

Especially in the winter when electricity or oil is frequently used for heating, fire is frequently generated in buildings, and the firefighting association emphasizes the fire protection function for the purpose of fire doors so as to prevent the fire from penetrating into fire doors.

However, in the prior art, when the cylinder is installed inside the cover, the open top and bottom of the door are filled with the heat insulating material. When a fire occurs inside or outside the building, flames and firearms are formed on the door cover supporting the door handle, The flame and the fire which are moved to the open top and the bottom move to the heat insulator which is very vulnerable to heat and spread widely inside the fire door, The function is lost.

In addition, if the flame spreads inside the fire door, it is difficult to evacuate through the fire door or to open the fire door for the evacuation due to an increase in the internal temperature, which causes difficulties in evacuation and rapid evacuation.

Particularly, as described above, in order to close the upper and lower protective covers, there is a problem of manufacturing a mold separately without using a conventional mold, and therefore, due to the cost of manufacturing an expensive mold, , And a protective cover with an open bottom is manufactured and sold. If such a protective cover with open top and bottom is installed in a fire door, there arises a problem that the fire protection effect to be provided by the fire door is deteriorated.

Each of the side walls 12 and 13 is formed with an installation hole 14 which is coupled with the cylinder 3 and through which the door handle 4 for opening and closing the fire door 1 can be installed.

The ends of the open side walls 12 and 13 of the main body may be formed in a straight line so that the sides of the side walls 12 and 13 may be stepped when inserted into the inside of the reinforcing bar 2.

Alternatively, the end portions of the side walls 12 and 13 may be folded inward by the thickness of the reinforcing bar 2, and then the reinforcing bar 2 may be unfolded to form a straight line fitting portion 15, Of the side walls 12 and 13 of the protective cover 10 along the reinforcing strip 2 provided on the fire door 1 may be formed so as to have the same height as the side walls 12 and 13 of the side walls 12 and 13, The shape can be selectively selected.

The upper and lower covers 20 and 30 are formed as a plate and are installed to close the upper and lower portions of the opened main body 11 with fixing means 40, 50 and 60, respectively. In the present invention, (40), (50) and (60) of branches.

The fixing means 40 of the first embodiment, as shown in Figs. 3 to 5,

The fixing grooves 41 are formed in the inside of the main body 11 so as to protrude inward from the side wall surfaces 12 and 13 of the main body 11 at positions deviated from the upper and lower ends.

The fixing groove 41 is formed so as to protrude from the outside of the both side walls 12 and 13 by pressing the upper and lower sides of the fixing groove 41. Preferably, And is pressed inwardly from the outer surface of the incision to form a groove.

The thus formed fixing grooves 41 may be formed in the upper part of the side wall surfaces 12 and 13 in a single or plural numbers and in the lower part thereof in the same number.

Both sides of the upper cover 20 at the corresponding positions to be fitted in the fixing grooves 41 are bent downward and the fixing cover portions 42 are formed at both sides of the lower cover 30 so as to be bent upward.

The fixing protrusions 42 are preferably protruded from both sides of the upper and lower covers 20 and 30 in a trapezoidal shape so as to be easily fitted into the fixing grooves 41. [

The fixing means 40 of the first embodiment thus constituted is constituted by fixing the upper cover 20 and the fixing protrusions 42 of the lower cover 30 to the fixing grooves 41 protruding inside the upper and lower openings of the main body 11 The upper and lower covers 20 and 30 are hammered into the upper and lower portions of the upper and lower covers 20 and 30 to close the upper and lower portions of the opened main body 11, Or the addition of an additive to increase the fireproof effect of the mold manufacturing cost can be lowered.

The fixing means 50 of the second embodiment, as shown in FIGS. 6 to 9,

Fixing grooves 51 are vertically formed to have a width and a length perpendicular to the upper and lower ends of both side walls 12 and 13 of the main body 11.

Therefore, the fixing groove 51 of the second embodiment is formed so as to open vertically through the upper and lower ends of the main body 11.

The fixing protrusions 52 are formed on the upper and lower covers 20 and 30, The protruding portion is protruded only by the thickness of the wall surface of the main body 11 so as not to deviate outwardly of the fixing groove 51. [

The reason for preventing the fixing protrusion 52 from deviating from the fixing groove 51 is that the side height of the reinforcing bar 2 and the main body 11 are the same when the fitting portion 15 is formed in front of the main body 11 In order to prevent the manufacturing failure of the fire door 1 in which both side plates are floated when the fixing protrusion 52 protrudes outward from the fixing groove 51 because the inner side surfaces of the two side plates of the fire door 1 are brought into contact with the same both sides, It is true.

The fixing means 50 of the second embodiment constructed as described above is provided with fixing projections 51 in the upper and lower fixing slots 51 in which the upper cover 20 and the lower cover 30 are located on the upper and lower portions of the main body 11, It is possible to close the opened portion by sandwiching the opening 52.

Alternatively, it is possible to further constitute the interference fit portion 51a which is formed to extend in the horizontal direction so as to form the inner end of the fixing groove 51 of the second embodiment.

When the interference fit portion 51a is formed as described above, the fixing protrusion 52 is inserted into the fixing groove 51 and then the front of the upper and lower covers 20 and 30 is struck to form the interference fit portion 51a. The lower and upper covers 20 and 30 can be prevented from being separated from each other while the upper and lower surfaces are locked and fixed while the fixed protrusion 52 moves.

It is preferable that the fixing groove 51 is formed to be wider than the width of the fixing protrusion 52 so that the fixing protrusion 52 can be easily inserted into the fixing groove 51 and then moved to the interference fit portion 51a And the upper portion of the interference fit portion 51a is inclined downward so as to be gradually smaller at the entrance portion, so that it is more preferable that the fixing projection 52 is deformed flatly.

Both sides of the upper and lower covers 20 and 30 constituting the fixing means 40 and 50 of the first and second embodiments are bent to form a " ).

The reinforcing portion 70 is configured to support and reinforce the main body 11 which is urged by an external force when the upper and lower covers 20 and 30 are installed on the main body 11, The fixing protrusion 42 which is the fixing means 40 of the first embodiment is formed to extend from the end of the reinforcing portion 70 which is elongated in the longitudinal direction or the reinforcing portion 70 may be formed at a position apart from the fixing protrusion 42 It can be bent.

In the fixing means 50 of the second embodiment, since the fixing protrusion is not bent, it is preferable that the reinforcing portion 70 is formed at a position deviated from the fixing protrusion 52 to an appropriate length.

The fixing means 60 of the third embodiment is, as shown in Figs. 10 and 11,

Like the first embodiment, the fixing grooves 61 are formed in the inside of the body 11 so as to protrude inward at positions offset from the upper and lower ends of the side wall surfaces 12, 13 of the body 11, respectively.

The upper cover 20 and the lower cover 30 are divided into two parts to constitute a fixed cover 62 and a moving cover 63. The upper surface of the moving cover 63 is fixed to the lower surface of the fixed cover 62 Respectively.

A fixing protrusion 62a protruding from a corresponding position of the fixed cover is formed to be inserted into the fixing groove 61 protruding from the one side wall 12 of the main body 11. Similarly, A fixing protrusion 63a is formed to be fitted into the fixing groove 61 protruding from the other side wall surface 13 of the main body 11. [

When the upper surface of the other side of the fixed cover 62 is pressed by a press to form the fixed position fixing protrusion 62b which is formed to protrude from the upper surface of the movable cover 63, And the position selecting grooves 63b are formed in a plurality of positions spaced from one side of the moving cover 63 in the other direction so that the position selecting grooves 63b are formed in the lower portion of the fixed cover 62 The fixed position fixing protrusion 62b is fitted into the position selection groove 63b formed at the proper position while the movable cover 63 is moved in the horizontal direction so that the fixed cover 62 and the movable cover 62 It is possible to adjust the length of the guide groove 63.

That is, when the fixed position fixing protrusion 62b of the fixed cover 62 is fitted in the position selection groove 63b formed on one side of the movable cover 63, the total length is the longest, The entire length of the fixing protrusion 62b is narrowest when the position fixing protrusion 62b is fitted in the position selection groove 63b formed in the fixing portion 63b.

The reason why the movable cover 63 is moved and adjusted in length is that the overall width of the fire door 1 is 40 mm, 45 mm and 48 mm. The thickness of the metal plate, which is installed on both sides of the fire door 1, The inner space of the 40 mm fire door 1 is secured to about 38.6 mm and the inner space of the 45 mm fire door 1 is secured to about 43.6 mm.

Although the main body 11 is produced in accordance with the fire doors 1 having different internal space sizes, the fixed cover 62 and the moving cover 63, which are obtained by dividing the upper and lower covers 20 and 30 into two, It is possible to reduce the production cost by applying each of the bodies 11 having different widths in a closeable manner and to increase the fire protection effect to such a degree that the existing protective cover is partially changed or added, It is possible to obtain the effect of lowering the cost.

Here, the plurality of position selection grooves 63b formed at intervals are not grooved but grooves. The reason for this is that when the fixed cover 62 and the movable cover 63 are extended the longest, the remaining position selection groove 63b is exposed to the outside without being clogged off the fixed cover 62, Grooves.

Further, if a size or an identification number indicating the width of the fire door can be displayed around the position selection groove 63b formed at the interval, the worker can quickly perform the assembly work.

When the fixing means of the third embodiment configured as described above is used, the fixed position fixing protrusion 62b of the fixed cover 62 is fitted and fixed to the position selection groove 63b of the movable cover in accordance with the width of the main body 11, When the fixed cover 62 and the movable cover 63 are fastened to an appropriate length by fastening them to the opened upper and lower openings of the protective cover 10, It is possible to obtain an action effect that can be fixed.

On the other hand, the reinforcing portion 70 is formed on one side of the fixed cover 62 and the other side of the moving cover 63 in the longitudinal direction, and the fixing projections 62a and 63a are formed on the respective ends thereof .

The fixed protrusions 62a and 63a support the side walls 12 and 13 of the main body 11 and the fixed position fixing protrusions 62b fitted in the position selection groove 63b at the center of the main body 11. [ So that the fixed cover 62 and the movable cover 63 can reinforce the main body 11.

As described above, the protective cover 10 having the upper and lower portions closed can be used for a digital door lock that opens the locking device by forming an elongated upper and lower length and pressing an electronic button, as shown in FIGS. 1 and 2, As shown in FIG. 12, the upper and lower lengths can be shortened so that the door lock can be generally used for a general door lock that opens the locking device with a key.

The protective cover 10 according to the present invention having the fixing means 40, 50 and 60 as described above can be used as an opening and closing means for opening and closing the upper and lower covers 20 and 30, The operation of reducing the mold manufacturing cost can be achieved by closing the lower part of the cover 10 or the movable cover 62 can be moved to the inside space of the protective cover 10 manufactured according to the fire doors of various sizes It is possible to provide a protective cover for a door of a fire door having a useful function of an open top and a bottom which can reduce the production cost by adjusting the length by using the movable cover 63.
