Definitions
- the innovation relates to a cushion according to the preamble of claim 1.
- Flap is no longer satisfied, or the misalignment can at least lead to the fact that when the flap is opened and closed the closure or the opening of the tone hole is not carried out in the desired manner at the same time over the entire tone hole edge.
- the innovation is based on the task of improving a generic cushion in such a way that this enables a reliable, uniform closure of the tone hole and supports an optimal sound of the instrument, in particular in the case of fast tone repetitions.
- This object on which the innovation is based is achieved by a cushion with the features of claim 1.
- the innovation proposes to use a material as the contact layer, which is referred to as the so-called final layer and which closes the edge of the tone hole, and which has comparatively slow resilience against indented deformations.
- a material which is referred to as the so-called final layer and which closes the edge of the tone hole, and which has comparatively slow resilience against indented deformations.
- the shaping of the tone hole edge which is adapted to the current key position, is maintained in this end layer and that only after a long period of time does the restoring force of the material give a flat surface of this end layer.
- misalignments of the flap which lead to a change in the contact surface on which the tone hole edge of this sealing layer lies, can be compensated for by the deformability of the sealing layer, in that the sealing layer adapts to these changed geometric conditions and always ensures a reliable
- a damping layer is provided behind the end layer, which is not as soft as the end layer, but has a medium hardness. In addition, this can
- Damping layer have a faster restoring force than the final layer. In this way it is ensured that each time the flap is reopened on the tone hole edge, this damping layer always has a constant thickness, so that the player is given a precise playing feel and a defined stop of the flap is achieved.
- An optimally adapted contour of the upholstery to the tone hole edge is ensured by the final layer, which - especially in the case of fast tone repetitions - still has a ring-shaped impression caused by the contact with the tone hole edge.
- the end layer and also the damping layer can advantageously each consist of an open-cell foam.
- the open-pore structure ensures problem-free pressure equalization, so that changed material properties, such as cannot be ruled out due to burst pores of closed-cell foams, can be reliably avoided and very much soft foam materials can be selected with a correspondingly good adaptability to the contour of the tone hole edge or to the edge of the tone hole chimney.
- a support layer can be provided, which supports the two layers mentioned above and which can be designed as stiff as possible in order to fit the cushion in these flap covers, which may be of very different designs, in adaptation to the most varied geometrical relationships of the inside of flap covers enable.
- the support layer in turn can be connected to the flap cover, in particular advantageously glued, so that the cushion can be easily installed in the
- Flap covers is made possible.
- the base layer can also be used to compensate for the thickness, that is, to achieve a predetermined total thickness of the upholstery.
- a number of base layers may be arranged on top of one another and connected to one another.
- the upholstery can consist exclusively of the mentioned closing and damping layers and, if necessary, the additional base layer.
- further intermediate layers may also be provided, e.g. B. in the form of double-sided self-adhesive films, which enable the connection of the three layers in a simple, fast and therefore inexpensive manner.
- the base layer consists of resin-bonded glass hollow fibers, since this creates a base layer with a very flat surface, which forms a good basis for the assembly of the other two layers. At the same time, a minimum weight of this base layer can be achieved with this composite material.
- the base layer advantageously has a temperature resistance, which enables such hot melt adhesives to be used without problems.
- a spacer can advantageously be provided in the middle of the cushion, projecting above the base layer.
- This central spacer which is directed towards the inside of the flap cover, allows the cushion to be tilted about its central axis, so that when the adhesive has tightened slightly and the cushion is securely held in the flap cover, the flap can be closed so that the cushion is closed optimally applied to the tone hole edge.
- the spacer can be designed as a mandrel and have a tip directed towards the flap cover, which is intended to prevent the spacer from shifting into an undesired position in a kind of aquaplaning effect on the flap cover while the adhesive is still liquid or pasty.
- Other forms of the end of the spacer facing the flap cover are also possible, e.g. B. mushroom- or dome-like rounded ends that allow a rolling movement of the spacer on the flap cover when tilting the cushion.
- a resonator can be provided which reflects a defined sound component from the tone hole when the flap is open.
- a resonator can preferably consist of a reverberant material, for example of metal, in particular of the same material and in the same material thickness as the instrument body. In this way, a well reflective resonator is created, the sound characteristics of which harmonize optimally with the instrument.
- a ring can advantageously be provided on the side of the base layer, which is directed towards the flap cover, which limits the adhesive to be used and prevents this adhesive from entering the annular gap which surrounds the cushion.
- a ring is preferably resistant in accordance with the adhesive to be used, for example temperature-resistant when using hot-melt adhesive, and such a ring is preferably made of a soft material in order to have sound-absorbing properties and for example to avoid flap noises which could otherwise occur when the flap is actuated.
- 1 indicates a wind instrument which has a tone hole 2 with a tone hole chimney 3, this tone hole chimney 3 ending with a tone hole rim 4.
- a flap 5 is arranged above the tone hole 2 and has a flap cover 6 which is shaped purely by way of example and is attached to an actuating arm 7.
- a cushion 8 is glued into the flap cover 6 and has a resonator 9 protruding into the tone hole chimney 3 on its underside.
- the resonator 9 is glued to an end layer 10, which is approximately 0.5 mm thick and has a very complete, but very sluggish resilience to impressed deformations.
- the closing layer 10 can consist of a film-like thin foam, in particular also of an open-cell foam, since in the area in which the closing layer 10 lies against the tone hole edge 4, the pores are compressed in such a way that an undesired escape of air when the flap is closed is excluded.
- the closing layer 10 is connected to a damping layer 11, which can also have a layer thickness of approximately 0.5 mm.
- the damping layer 11 has a significantly faster resilience and a greater hardness than the very soft final layer 10.
- the two layers 10 and 11 are arranged on a support layer 12, which can have a thickness of 3 to 4 mm, the layer thickness also being able to be considerably above or below in adaptation to the respective wind instruments in order to create a cushion which covers the flap cover 6 fills so far that an undesired misalignment of the flap cover 6 with respect to the tone hole chimney 3 when the flap 5 is closed is excluded.
- the support layer 12 consists of hollow glass fibers which are bonded to one another by synthetic resin, the support layer 12 having a bore in its center into which a spacer 14 is pressed.
- the spacer 14 is in the illustrated embodiment pointed as a mandrel to prevent the pad 8 from slipping during the solidification of the adhesive in the flap cover and a precise tilting movement of the pad when it bears against the tone hole edge 4 to enable a point.
- a ring 15 is also provided, for example a soft ring made of a foam material, this ring being provided as a limitation for an amount of adhesive 16.
- This adhesive can either be introduced shortly before the pad 8 is glued to the support layer 12 or in the flap cover 6, or the adhesive 16 can already be provided on the support layer 12 of the pad 8 similar to a solid tablet, so that the pad 8 is particularly easy to handle is.
- Such a cushion 8 can be inserted for repair purposes in the case of flaps of musical instruments in such a way that the flap, in particular the flap cover 6, is heated after the originally intended cushion was removed. In the heated flap cover 6 is now
- the adhesive provided on the upper side of the base layer 12 which is designed as a hot melt adhesive, melting and in this molten state making corrections with regard to the position of the cushion 8 possible.
- the hot-melt adhesive mentioned allows a simple later dismantling of the cushion 8 by heating the flap cover 6 again, but other adhesives instead of a hot-melt adhesive and in particular also other assembly methods instead of gluing for attaching the cushion to the flap 5 are possible, especially if the upholstery should not be attached to the flap as replacement or repair equipment, but as the manufacturer's original equipment.
- Adhesive 16 is achieved, the flap 5 can be closed _ s _
- the flap 5 remains in this state until the adhesive 16 has completely hardened, so that an optimal tight fit of the flap 5 on the tone hole chimney 3 is ensured. Later misalignments of the flap 5 to a greater extent can be corrected by reheating the adhesive 16 and repositioning the cushion 8, but slight misalignments of the flap 5 are already compensated for by the elastic properties of the cushion materials used.
