Description

TECHNICAL FIELD [0001] The present invention relates to a soundproofing system of a hinged door,

The present invention relates to a lower sound insulating apparatus for a hinged door, and more particularly, to a lower sound insulating apparatus for a door of a hinged door, more specifically, The present invention relates to a lower sound insulating apparatus for a hinged door capable of minimizing indoor energy loss as well as providing a residential environment.

Shingles are usually used as front doors of buildings. Such a hinged door has a form in which the door is pushed or pulled so as to rotate relative to an axis of a hinge or the like, unlike a sliding door in which a door is moved horizontally by a rail.

The hinged door is easy to manufacture and construct, and there is almost no possibility of defects, so if there is room in the rotation space, most doors are installed at the doors for accessing each room separately from the door as well as inside the building.

Since the hinged door is rotated with respect to the axis of the hinge or the like, the lower end of the hinged door must be slightly spaced from the bottom surface of the building to smoothly rotate the door.

However, the gap between the bottom of the door and the bottom surface not only causes outdoor noise to flow into the room, but also interferes with the pleasant living environment of the occupant, .

1, a flexible rubber plate 30 is installed at the lower portion of the door DR so as to block the gap between the door DR and the floor GR so that no external noise is introduced into the room . However, in this structure, since the rubber plate 30 continuously rubs against the floor surface GR when the door DR is closed, the door DR is not smoothly closed, And the rubber plate 30 is easily worn out, and the use life is very short, so that the rubber plate 30 must be frequently replaced.

In order to solve the problem of a general sound insulation structure in which a rubber plate is attached to the lower part of the door as described above, the invention of 'a soundproofing structure of a hinged door using a roller and a pressure plate, and a sound insulation assembly' of Registration No. 10-1079811 has been proposed .

The above-described hinged door structure disclosed in the registration number 10-1079811 has a concave recess 3 formed in the door frame 2, as shown in Fig. 2; The recess (3) is provided with a pressure plate (11) which is made of an elastic material and is curved convexly when both side edges are pressed, and the bent portion rises; Side pressure roller members 12 having rollers 121 and elastically expanding and contracting are provided on both sides of the pressure plate 11 such that both side edges of the pressure plate 11 are positioned below the rollers 121 ; The side pressure roller member 12 is configured to support the roller 121 to rotate so that the roller 121 is lowered by the downward force applied from the upper side and the roller 121 is raised again when the force is removed And an elastic stretching roller support 122 which elastically stretches the elastic stretching roller support 122; The elastic expansion and contraction roller support 122 includes a cylindrical fixing table 123 having a spring member having elasticity therein, and a lower member coupled to the cylindrical fixing table 123, And a stretching rod 124 coupled thereto; When the door is closed and the door 1 is positioned on the concave portion 3 of the door frame 2, the roller 121 protruding from the upper surface of the door frame 2 is moved downward by the movement of the door 1, The roller 121 is pushed downward and the both side edges of the pressure plate 11 are pressed so that the pressure plate 11 is convexly bent so that the pressure of the pressure plate 11 The convexly curved portion rises to press the door 1 and when the door is opened and the door 1 is released from the door frame 2, the roller 121 rises again and the bending of the pressure plate 11 is again unfolded Structure.

The width of the door frame is excessively large because the door frame structure is installed in the door frame, and the door frame structure of the door 121 has a problem in that the width of the door frame is too large, The gap between the roller 121 and the protective film 15 or the pressure plate 11 faces upward so that the foreign matter can be easily inserted and the rotation of the roller 121 is prevented, (1). Further, in the case of a concrete floor surface where a door frame is not installed, there is a problem in that it is difficult to construct the floor surface for installation of a sound insulation structure, and thus there is a restriction in place.

The housing 300 includes a vertical fixed shell 310, a fixed upper shell 320 installed horizontally at an upper portion of the fixed shell 310, And a fixed inner plate 330 opposed to the outer plate 310.

The fixed outer shell 310 has the same plane as the outer surface of one side of the door DR, thereby forming the outer side of the door DR itself. The fixed inner plate 330 may have the same plane as the other outer surface of the door DR. However, since the fixed inner plate 330 is installed inside the door DR as shown in FIG. 4, when the door DR is closed or opened, So that the stationary state of the sound insulating apparatus can be firmly maintained by supporting the sound insulating apparatus on the other outer surface of the door DR with respect thereto.

A movable sound-absorbing panel 400 is installed in the housing space S of the housing 300.

The movable sound absorbing panel 400 absorbs the noise introduced along the lower gap of the door DR and blocks the flow of air to prevent the noise that has not been absorbed from flowing into the room. And is slid in the vertical direction in a state of being in tight contact with the fixed inner plate 330. The movable body 410 for this operation and the sound absorbing pad 420 for absorbing and blocking noise are formed.

The movable body 410 is movable between the movable shell 411 and the movable upper shell 412 and the movable inner shell 413 so as to correspond to the fixed shell 310, the fixed upper shell 320 and the fixed inner shell 330 of the housing 300, .

 The sound absorbing pad 420 is also composed of the external sound absorbing pad 421 and the external sound absorbing pad 422 and the internal sound absorbing pad 423 so as to be respectively attached to the movable external plate 411, the movable top plate 412 and the movable internal plate 413 do.

The movable sound-absorbing panel 400 configured as described above must be moved while maintaining a state of being in close contact with the fixed outer shell 310 and the fixed inner shell 330 of the housing 300. In order to maintain such an adhered state, And is preferably provided between the inner surface of the housing 300 and the movable body 410.

FIG. 5 is a cross-sectional view of a sound insulating apparatus provided with an embodiment of the departure preventing means.

The movable shell plate 411 and the movable shell plate 413 are provided with a locking groove p formed in the vertical direction in the fixed shell plate 310 and the fixed shell plate 330 of the housing 300, The sound absorbing panel 400 is prevented from being deformed from the inner surface of the housing 300 due to an unexpected external force by providing the latching protrusion q inserted into the latching groove p.

The power unit 500 moves the movable sound-absorbing panel 400 upward by using the operation of the door DR when the door DR is rotated to open and close the door, First and second pair of gears 610 and 620, a fixed gear group 520 and a mobile gear group 530.

The roll bar 510 rotates together with the door DR in a state of being accommodated in the accommodation space S and being sealed so as to have airtightness on the bottom surface F when the door DR is rotated by opening and closing the door, And has a length corresponding to the width of the door DR so as to block noise and air from flowing from the floor F to the room.

The roll stick 510 is composed of an inner weight 511 and an outer turn adhesion pad 512. The turn adhesion pad 512 has elasticity so as to be pressed by the weight 511, And a serration protrusion 512a in the transverse direction is provided on the outer surface thereof. The material of the weight 511 need not be particularly limited, but it should have a weight capable of compressing the pivoting contact pad 512, and is preferably made of a metal material.

Therefore, when the roll bar 510 rotates, the serrated protrusion 512a is pushed by the weight body 511 in the portion of the pivoting contact pad 512 which is in contact with the bottom surface F to increase the contact area, (530) engages with the gear formed on the movable body group (530) and rotates the gear of the movable body group (530). (Not shown) may be provided at the center of the door width DR and the roll bar 510 may be rotatable at a fixed position with the bar shaft as a central axis. However, 6, it is desirable that the movement of the mobile device group 530 is performed more efficiently.

The first and second lever gears 610 and 620 are fixed to the respective inner surfaces of the movable outer plate 411 and the movable inner plate 413 in the vertical direction. Accordingly, when the first and second gears 610 and 620 are moved upward by the fixed gear group 520, the movable sound-absorbing panel 400 is also moved upward.

That is, the fixed gear group 520 is fixed to the first and second gear shafts provided on the door DR so that its position is fixed, and moves the first and second gears 610 and 620 upward when the roll bar 510 rotates.

The second pinion gear 523 meshes with the second ring gear 620. The first pinion gear 522 meshes with the first ring gear 610 and the second pinion gear 523 meshes with the second ring gear 620. [ And a driven gear 521 for transmitting the rotational force of the roll bar 510 received from the mobile device group 530 to the first pinion gear 522. The second pinion gear 523 is configured to be engaged with the second ring gear 620 and the first pinion gear 522 simultaneously.

The first pinion gear 522 and the driven gear 521 are integrally fixed to the first gear shaft 520a and the second pinion gear 523 is integrally fixed to the second gear shaft 520b.

Therefore, when the roll bar 510 rotates, the driven gear 521 rotates via the group of the moving device 530. When the driven gear 521 rotates, the first pinion 521 is rotated via the first gear shaft 520a, The gear 522 is rotated, and the first pinion gear 522 moves the first lever gear 610 engaged therewith. At this time, since the first pinion gear 522 is engaged with the second pinion gear 523, the second pinion gear 523 also rotates, and the second pinion gear 523 moves the second gear gear 620.

The movable finger group 530 is provided so as to be movable between the roll bar 510 and the fixed gear group 520 without being fixed in position so that the first and second gears 610 and 620 ) Is moved upward. That is, even if the rotation direction of the roll bar 510 changes to the normal rotation or the reverse rotation due to the opening / closing of the sliding door 530, the driven gear 521 always rotates in a constant direction. During the movement of the door DR, So as not to be attracted to the bottom surface (F) of the sound-absorbing panel (400).

However, most preferably, the first, second, and third moving gears 531, 532, 533 are disposed at the respective vertexes of the triangle formed by the fixed link 530a, The first and second moving gears 531 and 532 are always positioned at the bottom to engage the roll bar 510 and the third moving gear 533 is positioned at the top to engage the second moving gear 532, Only one of the first moving gear 531 and the third moving gear 533 is selectively engaged with the driven gear 521 in accordance with the rotation direction of the first moving gear 531.

6 illustrates the operating relationship of the movable finger group 530, which causes the movable sound-absorbing panel 400 to always move upward, regardless of the direction of the door DR or the movement of the roll bar 510, (a) shows a case in which the roll bar 510 rotates in a clockwise direction, and (b) shows a case in which the roll bar 510 rotates in a counterclockwise direction.

For example, when the roll bar 510 rotates clockwise as the door DR is rotated to open or close the hinged door, as shown in FIG. 6 (a), the roll bar 510 rotates in the first The second moving gears 531 and 532 are rotated counterclockwise to move the entire moving group of gears 530 to the upper right portion so that the first moving gear 531 is engaged with the driven gear 521. At this time, the third moving gear 533 is separated from the driven gear 521.

Further, the driven gear 521 rotates in the clockwise direction, and the first pinion gear 522 also rotates clockwise through the first gear shaft 520a. Accordingly, the first lever gear 610 engaged with the first pinion gear 522 moves the movable shell plate 411 upward while moving upward.

On the other hand, the second pinion gear 523 engaged with the first pinion gear 522 rotates in the counterclockwise direction, and the second gear gear 620 engaged with the second pinion gear 523 moves upwards to move the movable inner plate 413 Up.

When the roll bar 510 is rotated in the counterclockwise direction by reversely rotating the door DR to close or open the hinged door, as shown in FIG. 6 (b), the roll bar 510 is rotated in the first The second moving gears 531 and 532 are rotated clockwise to move the entire moving element group 530 to the upper left portion to cause the third moving gear 533 to engage with the driven gear 521. At this time, the first moving gear 531 is separated from the driven gear 521.

At this time, since the driven gear 521 is engaged with the third moving gear 533 via the second moving gear 532, the driven gear 521 rotates clockwise in the same manner as in FIG. 6 (a) So that the first pinion gear 522 also rotates in the clockwise direction. The first pinion gear 522 meshes with the first pinion gear 522 and the second pinion gear 522 meshes with the first pinion gear 522 and moves the movable shell 411 upward while moving upward. And moves the second lever gear 620 and the movable inner plate 413, which are engaged with each other, in the clockwise direction.

The moving gear unit group 530 can move the movable sound absorbing panel 400 to the bottom surface F during the movement of the door DR by changing gears engaged with the fixed gear group 520 according to the rotation direction of the roll bar 510, So that a dragging phenomenon of the movable sound-absorbing panel 400 does not occur.

However, when the hinged door is closed, that is, when the door DR is stopped, the first and second pinion gears 522 and 523 rotate counterclockwise and clockwise respectively due to the self weight of the movable sound- And moves the fishing gear 530 to a neutral position so as not to interfere with the rotation of the first and second pinion gears 522 and 523. The first pinion gear 522 pushes the first moving gear 531 to the lower left portion and the third pinion gear 522 pushes the third moving gear 533 toward the left lower portion, The first pinion gear 522 pushes the third moving gear 533 to the right lower portion when it is engaged with the first pinion gear 522. Accordingly, when the hinged door is closed, as shown in FIG. 7, the lower end of the movable sound-absorbing panel 400 is brought into close contact with the floor F to form multiple airtight structures with respect to the floor F.

The first pinion gears 522 may be constructed of a dual structure of the inner pipe 522a and the outer pipe 522b separated from each other so that the movable sound-absorbing panel 400 can be lowered at the time of stopping the door (DR) have.

FIG. 8 is a cross-sectional view of the structure of the first pinion gear 522 of the double structure.

The double pinion first pinion gear 522 has an inner pipe 522a that rotates integrally with the driven gear 521 and a closed space formed between the inner pipe 522a and the inner pipe 522a The outer appearance 522b. The viscous oil 522c is filled in the closed space.

The inner pin 522a and the outer pin 522b are rotated together by the frictional force of the viscous oil 522c of the first pinion gear 522 having such a double structure. That is, as the driven gear 521 rotates, the inner pipe 522a of the first pinion gear 522 rotates together via the first gear shaft 520a, and between the inner pipe 522a and the outer pipe 522b Frictional force is generated via the viscous oil 522c, and the outer tube 522b is rotated along the inner tube 522a by the frictional force.

However, if the driven gear 521 is not rotated due to the stopping of the roll bar 510, the inner pipe 522a is maintained in the stopped state as it is. However, the viscous oil 522c is held between the inner pipe 522a and the outer pipe 522b The lowering of the movable sound-absorbing panel 400 due to its own weight is made easier.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious that it will be possible to carry out various modifications thereof. It is therefore intended that such modifications are within the scope of the invention as set forth in the claims.
