Definitions

• the invention relates to a cabinet furniture with a furniture body and at least one front blind, which has mutually parallel interconnected profile elements and which is guided in the body arranged on the guide grooves.
• Such cabinet furniture are already known from the prior art.
• cabinet furniture in which profile elements for forming a shutter with each adjacent profile elements are pivotally connected and which are provided for opening or closing this cabinet furniture.
• the arranged in various types of profile elements in cabinet furniture shutters or front blinds cause when opening and closing due to the material itself noises.
• a disadvantage of these cabinet furniture from the prior art is seen that, especially when used in, for example, open-plan offices with a high level of noise, the use of this cabinet furniture to distribute the sound level causing sound, as this on the surface of the cabinet furniture and especially the front blinds is reflected back.
• DE 103 43 956 discloses a cabinet furniture with a furniture body and a front blind, which has parallel profile elements, here called lamellae, and is guided in arranged on the end faces in the walls of the furniture body guide.
• This cabinet furniture should be designed so that the blind can have comparatively high profile elements.
• This is to be achieved by the fact that the profile elements are connected at their front sides with linking members, which have on their side facing the center of the front blind side connecting portions with the profile elements and respectively on the outwardly facing to the walls sides in the guide grooves engaging pivot pin over Pivoting eyelets are connected to the respective adjacent linking member.
• a disadvantage of this cabinet furniture is seen that a sound amplifying effect is achieved by the geometry and the material used of the profile elements of the front blind, since the resulting example in office space sound is reflected back over a large area.
• the invention is therefore based on the object to improve the disadvantages of the known prior art and to show cabinet furniture that are economical and inexpensive to produce and that are improved in particular in terms of sound-absorbing properties.
• the cupboard furniture according to the invention is characterized in that at least one opening is introduced in at least one profile body.
• This solution is simple and has the advantage that the sound can penetrate through the opening in the profile body of the profile element in the cabinet furniture and spread there.
• the sound is at least partially absorbed in the cupboard furniture.
• the reflected back from the cabinet furniture sound is now at least partially reflected back from the profile elements of the front blinds in the cabinet furniture, so that only a very small proportion of the sound is reflected back into the room.
• the incident sound passes through the openings of the first profile body and propagates in the cavity formed by the second profile body or is reflected back to the existing between the openings of the first profile body wall of the profile body.
• the sound absorption effect is thus achieved in the profile element itself, so that also only small portions of the incoming sound are reflected back into the room.
• the width of the opening is less than half the width of the front side of the profile body of the profile element is preferably less than one third.
• a size of the surface of all openings of the profile body of the profile element of less than 45% or more than 3% of the surface of the front of the profile body of the profile element leads to dimensionally stable profile elements or front blinds, which depending on the size of have generating surface optimized sound absorption effects.
• the openings are regularly spaced apart, whereby on the one hand the design of the front blinds formed by the profile elements can be designed according to customer requirements, while on the other hand a simultaneously optimized sound absorption effect is present. Furthermore, it has proven advantageous that the spacing of the openings is greater than or equal to the extent of the opening in the longitudinal direction of the profile body of the profile element. Due to these production-technically simple possibilities and the resulting diverse designs, cabinet furniture with front blinds with optimized sound absorption effects can be realized for many requirements. In a further embodiment of the cabinet furniture according to the invention, the distance of the openings in the longitudinal direction of the profile body of the profile element is greater than or equal to twice the extent of the opening seen in the cross section of the profile body of the profile element. As a result, cabinet furniture can be produced with formed by the profile elements front blinds, which have an attractive design optimized sound absorption effects.
• a sound-absorbing material is arranged as part of at least one soundproofing element on the profile body of the profile element.
• This soundproofing element can be arranged both on the first profile body and / or on the second profile body of the profile element.
• a soundproofing element is arranged at least in the region of the opening to the opening and can already eliminate large components thereof when the sound penetrates through the opening of the profile body of the profile element.
• the penetrating through the openings of the profile body of the profile element sound propagates such that it comes into contact with at least a majority of the surface of the soundproofing element and is absorbed.
• the front blinds with profile elements without such sound-absorbing material the sound absorption effects of a cabinet furniture according to the invention can be significantly improved.
• the soundproofing element is arranged at least in the region of the opening to the opening and movable from it, so that the penetrating sound moves the soundproofing element in the sound direction and thus contributes to a better absorption of the sound.
• the soundproofing element is arranged on the front side of the profile body of the profile element, so that advantageously in addition to the sound-absorbing properties, design and design possibilities for customized cabinet furniture are possible.
• the soundproofing element is arranged on the underside of the profile body of the profile element, so that the openings introduced in the profile body of the profile element channeled the incoming sound to the soundproofing element and the design of a cabinet furniture is the wishes of each customer customizable.
• the soundproofing element is arranged both on the front side and on the underside of the profile body of the profile element, which leads to even more optimized soundproofing effects of the cabinet furniture.
• the soundproofing element is arranged both on the first profile body and on the second profile body, so that the soundproofing effects of the cabinet furniture are further improved.
• the soundproofing element is arranged only on the second profile body of the profile element, so that the optimized soundproofing effect can be realized without the soundproofing element being visible to the user of the cabinet furniture.
• the formation of the soundproofing element as a substantially mat-shaped leads to advantageous production costs of such inventive cabinet furniture.
• the sound-absorbing material may be a fiber material with which it is possible in a simple manner to obtain cost-effective sound-absorbing properties of the cabinet furniture.
• the sound-absorbing material is a non-woven material, which is characterized by very good sound-absorbing properties and very good processability.
• the soundproofing element can be formed by a membrane, for example made of plastic. With such a membrane, material-specifically targeted desired sound frequencies can be influenced and absorbed accordingly.
• the soundproofing element extends over the entire length of the profile element, which leads to cost-effectively manufacturable cabinet furniture with optimized sound absorption effects.
