The present invention relates to a prevention device that is installed on a door frame of an opening/closing door to prevent sudden closing of the opening/closing door, and more particularly, to an impact noise prevention device for an opening/closing door which is configured to install wings on one side of a hinge fixed to the door frame, allows the wings to rotate around the hinge by the force of the wind passing between the opening/closing door and the door frame, i.e. the wind force, thereby reducing the impact and noise caused by the sudden closing of the opening/closing door, and is installed in the door frame to conveniently perform its installment and removal.
Generally, an opening/closing door is often used for entry and exit purposes inside a residential or office building. Such opening/closing door is often left in an open state for airing and ventilation for a comfortable indoor environment. If the door is left in the open state as it is, it often closes suddenly due to an unexpected strong wind coming in from the outside. Moreover, just before the opening/closing door is closed by the wind coming in from the outside, the wind speed of the draft passing through a narrow space between the door and the door frame is rapidly accelerated, and at this time, as the door is suddenly closed, a large impact and a large noise are generated.
The problems caused by the sudden and frequent closing of such opening/closings by strong winds are that safety accidents such as injury accidents occur frequently, including loud noise, damage, and cracks due to strong impact between the door and the door frame, and getting indoor elderly people, infant and children′ hand caught in the door, and loud noise startle people and disturbs the sleep of infants and children.
Existing tools with the function of door closure prevention, that is, a fixture under the door, a tool for fitting the side of the door, and other devices, not only have the hassle of having to be directly installed and removed by the user to prevent the door from closing, but also always be operated directly by the user, and when the act of fixing or fitting is momentarily missed in order to prevent the door from closing due to strong wind from outside, the user is exposed to accidents that may occur due to unexpected door closures, and thus, cannot be completely freed from the dangerous situation.
As the related prior art, Korean Registration Patent No. 10-1084538 suggests a door closing prevention stopper.
The above patent suggests a door closing prevention stopper in which an attachment plate 11 attached to a door frame 22 forms a fitting tool 13 so that the pedestal 12 is inserted and rotated, and when inserted into the fitting tool 13 and rotated to either side, a support 12 is configured to have a length that abuts against the door 21 and prevents the door 21 from closing, characterized in that the supports 12′ having various lengths are inserted into the attachment plate 11 to form a plurality of fitting tools 13 that rotate, and a plurality of supports 12′ having different lengths are configured so that the positions of contact with the door 21 are different. However, the support always hits the specific position of the door, and the longer the period of use, the more the door is damaged. In particular, when the door needs to be completely closed, the support must be completely rotated, which leads to discomfort in use.
As another related prior art, Korean Registration Utility Model Publication No. 20-0362906 suggests an opening/closing door closing prevention device, which is provided in the space between the opening/closing door and the door frame to support the opening/closing door so that it does not close in the open state, characterized in that the device comprises a first support plate 10 in which one side is formed with a first hinge shaft 11 and both ends are formed to be able to perform a seesaw movement around the first hinge shaft 11; a second support plate 20 in which one side is formed with a second hinge shaft 21, and both ends are formed so as to be able to perform a seesaw movement around the second hinge shaft 21, and are coupled to intersect with the first support plate 10; a pin shaft 30 that axially couples the first hinge shaft 11 of the first support plate 10 and the second hinge shaft 21 of the second support plate 20 on the same line; and an elastic spring 40 that is provided between the first support plate 10 and the second support plate 20 and elastically supports the first support plate 10 and the second support plate 20. However, since the opening/closing door closing prevention device must be installed by inserting it between the opening/closing door and the door frame, the installation is difficult, and the door may be difficult to close completely.

The present invention relates to a prevention device that is installed on a door frame of an opening/closing door to prevent sudden closing of the opening/closing door, and more particularly, to an impact noise prevention device for an opening/closing door which is configured to install wings on one side of a hinge fixed to the door frame, allows the wings to rotate around the hinge by the force of the wind passing between the opening/closing door and the door frame, i.e. wind force, thereby reducing the impact and noise caused by the sudden closing of the opening/closing door, and is installed in the door frame to conveniently perform its installment and removal.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
First, the opening/closing door 10 is a door used for entering and exiting the interior of a residential or an office building, and is a door that is closed by an opening and closing method, where a rectangular door frame 11 to which the opening/closing door is fixed by a fixing member such as a hinge is installed around the opening/closing door 10 to open and close the opening/closing door 10.
The fixing plate 1 having a bolt hole formed in the door frame 11 is fixedly coupled by bolts 9, the hinge 2 is a shaft fixed to the fixing plate 1, the rotating pipe 3 is a hollow pipe coupled in a state of being penetrated by the hinge 2 and rotated around the hinge 2, a wing 4 is installed on one side of the rotating pipe 3, and the wing 4 is rotated by the force of the wind passing between the opening/closing door 10 and the door frame 11, that is, the wind power.
Here, in the illustrated embodiment, the fixing plate 1 is fixed to the door frame 11 by bolts 9, but in some cases, the fixing plate 1 may be fixed to the door frame 11 by applying adhesive to the fixing plate 1 or using an adhesive member such as an adhesive sticker, and the fixing plate 1 itself can be made in the form of a vacuum suction plate to provide convenience of attachment and detachment.
In addition, a front cushioning member 5 is attached to the front of the wing 4, and a cushion 6 is attached to the front cushioning member 5, which absorbs the impact generated when the opening/closing door 10 is suddenly closed, thereby reducing noise.
That is, the front cushioning member 5 is a cushioning member attached to the front of the wing 4, and is installed in the structure in which a cushion 6 is further attached to the surface of the front cushioning member 5, and when the opening/closing door 10 closes, it first hits the cushion 6 and absorbs the impact, and such impact of the cushion 6 is again absorbed by the front cushioning member 5.
In the illustrated embodiment, the wing 4 is shown to be square when viewed from the front, but in some cases, it can be made in various shapes such as circular, polygonal, heart-shaped, airplane wing-shaped. In particular, when the same wind force acts, it is preferable to have a shape in which the rotational force of the blade is larger even if the area is the same.
Moreover, the front cushioning member 5 and the cushion 6 are preferably configured such that the amount of deformation of the cushion 6 is larger than the amount of deformation of the front cushioning member 5 when the same force acts on the same area.
That is, the cushion 6 is made from a relatively soft material, and the front cushioning member 5 is made from a material that is relatively harder than the cushion 6. Thus, the impact caused by the closing of the opening/closing door 10 is first absorbed by the cushion 6, and then absorbed by the double structure in which the front cushioning member 5 of a hard material absorbs again, thereby preventing the generation of loud noise.
In addition, a rear cushioning member 7 is further attached to the rear surface of the wing 4, and the rear cushioning member 7 can absorb the impact generated when the opening/closing door 10 is opened, thereby reducing the impact.
That is, when the door is opened as shown in
In addition, the hinge 2 is a cylindrical shaft, and the rotating pipe 3 may be made from a bushing.
That is, the bushing is one of the oilless bearings, and is penetrated and coupled by the hinge 2, which is a cylindrical shaft, and minimizes the frictional force with the hinge 2, so that when the door 10 is closed, the wind can make the rotation motion of the blades 4 more rapid.
That is, the aeration hole 4a allows the wind passing around the wing 4 to pass through the surface of the wing 4 to the opposite side, and thus can serve to more smoothly perform the rotational operation of the wings 4.
Next, the operation method of the present invention will be described with reference to
In a state where the opening/closing door 10 is left open for airing or ventilation as shown in
Therefore, the impact generated by the sudden closing of the opening/closing door 10 is absorbed by the cushion 6 and the front cushioning member 5 installed on the wings 4, thereby preventing noise from being generated.
In particular, as the opening/closing door 10 is closed, the space through which the wind W can pass between the opening/closing door 10 and the door frame 11 is reduced. The wind moves at a faster speed in the state of
In addition, the opening/closing door 10 does not completely close even by the wind of high wind speed, and therefore, it is possible to prevent safety accidents such as getting infant or children's hands caught in the door gap.
Further, referring to
Eventually, an impact noise prevention device for an opening/closing door according to the present invention is a prevention device that is installed on a door frame of an opening/closing door to prevent sudden closing of the opening/closing door, and is configured to install wings on one side of a hinge fixed to the door frame, and allows the wings to rotate around the hinge by the force of the wind passing between the opening/closing door and the door frame, i.e. the wind force, thereby reducing the impact and noise caused by the sudden closing of the opening/closing door, and is installed in the door frame to conveniently perform its installment and removal. Further, a front cushioning member is attached to the front surface of the wing, and a cushion is attached to the front cushioning member, which absorbs the impact generated by sudden closing of the opening/closing door, thereby reducing noise, and a rear cushioning member is further attached to the rear surface of the wing, and rear cushioning member can absorb the impact generated when the opening/closing door is opened, thereby reducing the impact noise.
