Description

AUTOMATIC CLOSING STRUCTURE FOR AUTOMATIC DOOR
Description Technical Field The present invention relates to an automatic closing structure of a reinforced automatic door. In particular, the invention relates to such a closing structure, in which an uppe_r hinge axis and a lower hinge axis do not lie on the same straight line, but is displaced by a certain angle such that the door can be automatically closed due to its gravity, without using a conventional hinge formed of an hydraulic force and a. spring, thereby enabling an automatic closing of the door by aι weak force, and also providing an automatic closing structure through a simple structural change.
Background Art Generally, a reinforced door includes a reinforced glass pane, which is manufactured by heating up to a softening"
temperature ranging from 500°C to 600°C and then rapid-cooling the surface thereof such that the surface area is compression- strained and the internal area thereof is tensile-strained. The reinforced glass pane is supported by a glass support frame, which is rotatably attached to the door frame by a hinge in such a way that the reinforced door can be rotationally opened and closed. For example, one hinge is installed in the door frame, and the other is embedded in the floor. FIG.l shows an example of a conventional reinforced door, in which a floor hinge is installed. In FIG.l, reference numeral 1 denotes a reinforced glass pane, reference numeral 2 denotes a door frame, reference numeral 3 denotes a glass support frame, reference numeral 4 denotes a hinge, and reference numeral 5 denotes a hydraulic hinge. As shown in FIG. 1, the conventional reinforced door includes a glass support frame 2, which supports the upper and lower portions of the reinforced glass pane 1. The glass support frame 2 with the glass pane supported therein is installed in the door frame 3 formed in the wall by means of a hinge 4 formed in the upper portion of the door frame and a hydraulic hinge 5 provided in the floor. In the conventional reinforced door having the above- described hinge, however, the hinge is constructed of a hydraulic spring structure to provide an automatic closing function. Therefore, the user must push the door with a great force in order to open it . In the case where several people try to pass through the door back to back, the strong restoring force of the hydraulic hinge is prone to cause an injury to the rearward persons, in particular dangerous to weak women and elderly people, and children. Furthermore, as the conventional reinforced door having the hydraulic hinge is repeatedly opened and closed, the resilient force of the hinge spring becomes weakened or the hydraulic force is leaked, so that the door frame and the glass support frame become spaced apart to thereby form a gap therebetween. Therefore, the outside air or dirt is in-flown into the inside of the room or house through the gap. Accordingly, the conventional reinforced door needs an increased maintenance cost in order to repair the gap, or the like. On the other hand, the conventional reinforced door employs the spring action, of the hydraulic hinge for automatic closing thereof, which leads to a complicated structure of the door. In addition, the door cannot be smoothly closed due to the force required for the automatic closing, together with the gravity of the door itself. Also, the door is likely to be closed so forcefully owing to the restoring force of the hinge, along with the gravity of the door. Furthermore, the hydraulic hinge must be installed or embedded in a desired position on the floor where the door is installed, and thus the reinforced door cannot be easily and conveniently installed.
Disclosure of Invention Technical Problem
The present invention has been made in order to solve the
above problems in the art, and it is an object of the invention
to provide an automatic closing structure of a reinforced
automatic door, in which an upper hinge axis and a lower hinge
axis is tilted such that the door can be automatically closed
due to its gravity, without using a conventional mechanism,
thereby enabling an automatic closing of the door by a weak
force, and an easy installation thereof.
Technical Solution In order to accomplish the above object, according to one
aspect of the invention, there is provided an automatic closing
structure of a reinforced automatic door. In the automatic
closing structure of the invention, a door is formed of a glass
support frame with a reinforced glass pane fixed inwards thereof .
The door is hinged to a door frame through an upper hinge and a
lower hinge formed respectively at the upper and lower side of
the glass support frame such that a line passing the upper and
lower hinges is tilted inwards of the door frame by a certain
degree of hinge angle θ.
Advantageous Effects
In the automatic closing structure of a reinforced automatic door according to the invention, a line passing the upper and lower hinges is tilted such that the door can be automatically closed due to its gravity, without using a conventional mechanism, thereby enabling an automatic closing by a weak force, and an easy installation thereof, and providing the product efficiency.
Brief Description of Drawings Further objects and advantages of the invention can be more fully understood from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. 1 is an elevational view of a conventional reinforced automatic door; FIG.2 is an elevational view illustrating an automatic closing structure of a reinforced automatic door according to the invention; and FIG. 3 is an elevational view showing the automatic closing structure of the invention where the door is turned open.
Best Mode The preferred embodiments of the present invention will be hereafter described in detail with reference to the accompanying drawings . FIG.2 is an elevational view illustrating an automatic closing structure of a reinforced automatic door according to the invention, and FIG. 3 is an elevational view showing the automatic closing structure of the invention where the door is turned open . As illustrated in FIG. 2, in the automatic closing structure of the reinforced automatic door of the invention, a door 10 is constructed by a glass support frame 2 with a reinforced glass pane 1 supported inwards thereof . In the door 10 as constructed above, the glass support frame 2 is hinged to a door frame 3 in such a manner that it is hinged at the upper side thereof by an upper hinge 20 and at the lower side thereof by a lower hinge 30. Here, the door 10 is hinged to the door frame 3 by means of the upper hinge 20 and the lower hinge 30 such that the line passing the upper and lower hinges 10 and 30 (hereinafter, referred to as a "hinge line") is tilted at a certain hinge
angle θ relative to the vertical line thereof. In this way, the door 10 has an upper face 11 and a lower face 13 in parallel to each other, and also a left and right side faces perpendicular to the floor and also in parallel to each other, as shown in FIG. 3. However, the upper and lower hinges 20 and 30 are positioned in such a manner as not to lie on a vertical line to the floor. The operation and effects of the invention having the above-described construction will be described hereafter. First, as shown in FIG. 3, when the door 10 is opened inwardly or outwardly, the lower face of the door 10 is lifted upwards while being opened since the hinge line is tilted at the
hinge angle θ towards the door frame and relative thereto. In this way, since the door 10 is lifted upwards when opened, the gravity of the door weight generates a force in order for the door to be kept returning to its original place, i.e., to the closed position thereof, thereby automatically closing the door. As described above, the door 10 is opened lifting itself
upwards a little by means of the hinge angle θ, and closed automatically by means of the gravity of the door, thereby providing a simplified structure capable -of carrying out an automatic closing function.
Industrial Applicability As described above, in the automatic closing structure of a reinforced automatic door according to the invention, a line passing the upper and lower hinges is tilted such that the door can be automatically closed due to its gravity, without using a conventional mechanism, thereby enabling an automatic closing by a weak force, and an easy installation thereof, and providing the product efficiency. While the present invention has been described with
reference to the particular illustrative embodiments, it is not
to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the
scope and spirit of the present invention.
