DE102020203142B4 - Noise control door - Google Patents

Abstract

A noise protection door with a simpler structure and a handle unit for such a noise protection door is specified, which transmits as little sound as possible from one side of the noise protection door to the other side of the noise protection door. Because the two door leaves connect directly and directly to one another, no common carrier element is necessary. This results in a simplified structure and lower weight with a consistently high level of sound insulation.

Description

Technical area

The present disclosure relates to a noise protection door according to claim 1 and a handle unit therefor according to claim 6.

From the pamphlets DE 1 253 437 A , DE 2 257 434 B and DE 1 226 277 B a noise protection door with two door leaves and a common support element between them is known in each case. The two door leaves are connected to the common carrier element via connecting components. Each connection component has a first and a second connection element which interlock with one another. A vibration damping element is arranged between the interlocking connecting elements. The common carrier element results in a heavy and complex construction of the noise protection door.

Also from the CH 322 905 A and the CH 632 038 A noise protection doors, each with a first and a second door leaf, which are connected to one another at a distance from one another by means of connecting components, are known.

Based on the determined prior art, the object of the present invention is to specify a noise protection door with a simpler structure. A further object is to specify a handle unit for such a noise protection door which transmits as little sound as possible from one side of the noise protection door to the other side of the noise protection door.

These objects are achieved by the features of claims 1 and 6, respectively.

Because the two door leaves connect directly and directly to one another, no common carrier element is necessary. This results in a simplified structure and lower weight with a consistently high level of sound insulation.

The advantageous embodiment according to claim 2 results in a stable construction.

The assembly of the noise protection door is simplified by the advantageous embodiment according to claim 3.

The advantageous embodiment according to claim 4 results in the sealing or closure of the noise protection door to the frame.

Sound absorption is additionally improved by sound-absorbing material between the door leaves - claim 5.

The handle unit according to claim 6 is only connected to one door leaf and has no connection to the second door leaf. This minimizes the transmission of sound from one side of the soundproof door to the other.

Due to the advantageous embodiment according to claim 7, the grip sleeve is not visible from the outside and does not impair the appearance of the soundproof door.

Description of the exemplary embodiments

the 1 , 1a , 1b , 1c and 2 show an exemplary embodiment of the noise protection door with a first door leaf 1 and a second door leaf 2 each one inside 1-1 and 2-1 and an outside 1-2 and 2-2 have and have four connecting components 4th are connected to each other. The connecting components 4th are in the corner areas of the inner sides facing each other 1-1 and 2-1 of the two door leaves 1 , 2 arranged. Each of the four connecting components 4th comprises a first and a second connecting element 41 , 42 that interlock, and an elastic vibration damper element 43 that is between the interlocking fasteners 41 and 42 is arranged. The first connector 41 comprises a first metal plate 41-1 with two screw holes 44 and one perpendicular to the screw holes 44 running receiving opening 41-2 who have favourited the first metal plate 41-1 interspersed. The second connecting element 42 comprises a second metal plate 42-1 also with two screw holes 44 and a screw 42-2 that are in a centering element 42-3 is screwed in the form of a metal mandrel. The centering element 42-3 is tapered and engages in the receiving opening 41-2 of the first connecting element 41 a. The first connecting elements 41 are with the inside 1-1 of the first door leaf 1 and the second connecting elements 42 are with the inside 2-1 of the second door leaf 2 firmly screwed. The fasteners 41 , 42 are dimensioned so that there is no contact between the first connecting elements 41 and the second door leaf 2 and no contact between the second connecting elements 42 and the first door leaf 1 consists. Through the surrounding frame 2-3 on the second door leaf 2 remains in the edge area of the two door leaves 1 , 2 just a narrow gap 5 . This narrow gap 5 between the first and second door leaf 1 , 2 is all-round with a vibration-damping seal 61 , e.g. B. sealed in the form of a seal made of foam rubber.

Through the connecting components 4th become the two door leaves 1 , 2 firmly connected to each other and by the elastic vibration damper elements 43 become the two door leaves 1 , 2 acoustically decoupled from each other. On the side and top of the first door leaf 1 is a door rebate seal 62 provided, which seals the noise protection door against the frame. To seal against the floor is in the first and second door leaf 1 , 2 a bottom seal 63 intended.

The elastic vibration damper element 43 includes a plastic plate 43-1 with a central opening 43-2 that is between the first and second metal plates 41-1 , 42-1 is arranged. The central opening 43-2 is aligned with the receiving opening 41-2 in the first metal plate 41-1 . The elastic vibration damper element 43 further comprises a plastic ring 43-3 that is in the receiving opening 41-2 is arranged. In the direction of engagement of the centering element 42-3 is the plastic ring 43-3 through a circumferential groove 41-3 in the receiving opening 41-2 fixed. With this arrangement, there is no direct contact between the first and second connecting elements 41 , 42 .

The centering element 42-3 can also consist of a hard plastic instead of metal.

3 and 4th show a handle unit 8th for soundproof doors, which is particularly suitable for a soundproof door according to the present invention. The handle unit 8th includes first and second pawls 8-1 , 8-2 that have a connecting shaft 8-3 are rigidly connected to each other. The connecting shaft 8-3 is about a pivot bearing 8-4 rotatable in a grip sleeve 8-5 stored. The grip sleeve 8-5 includes a fastening ring 8-6 that extends from the outer surface of the grip sleeve 8-5 stretches away. The grip sleeve 8-5 is about the mounting ring 8-6 with the first door leaf 1 screwed. The fastening ring 8-6 is with the inside 1-1 of the first door leaf 1 , screwed and penetrates the second door leaf 2 without contact with this. The grip sleeve 8-5 also penetrates the first door leaf 1 partially. This creates a sound bridge between the two door leaves 1 , 2 avoided.
