Description

TECHNICAL AREA

The invention relates to a support device for arranging a stringed instrument on the floor, comprising a foot element, a receiving element and a connecting element.

STATE OF THE ART

A large number of support devices for arranging a stringed instrument on the floor are known. With a cello in particular, the support on the floor when playing is via a so-called spike (as a fixed component of a so-called end pin solution) with a selective contact surface. As a result, there is a risk of damaging the floor, and conventional devices also hold poorly or not at all on very hard materials such as stone. Since the user needs both hands to play the cello and playing involves moving the instrument, a secure stand for the cello is a prerequisite for technically correct playing. With conventional systems, it is also necessary to fix the cello with your knees. This is particularly important when the playing angle is flat, because then the tip can no longer grip the ground well. For these reasons, there is a large number of aids on the market that have to be placed on the floor: small plates, slabs, etc., which are designed as so-called parquet floor protectors with anti-slip properties on the floor. The spike must then be placed in the central depression of this plate each time before playing. The little plates have a soft rubber-like underside, which has the disadvantage that the adhesive property decreases very quickly when it is dirty and dusty and the spine with the plate slips away during games. To prevent this, floor protectors were developed, which are connected to the player's chair. These straps and cord systems must be adjusted to the correct length by the player each time, and must be readjusted each time the cello changes position. The disadvantage of this system is that the connecting parts to the chair interfere with the player's legroom and are often tripped over. Another disadvantage is that the cello also has to be fixed with the knees, even more than is the case when playing with the normal point, because the point slips around in the central depression of the plate. There are solutions for this, which have plates that have several holes for different positions and tip diameters. The problem of the connecting parts slipping away to the chair and the limited freedom of position remains, however, and in each new game situation the system has to be manually recalibrated to the player's playing style.

With the present invention, evident advantages arise through its technical progress, which solves all the aforementioned problems.

OBJECT OF THE INVENTION

Proceeding from this prior art, it is an object of the present invention to provide a support device for arranging a stringed instrument that is suitable for ensuring that the instrument stands securely on the respective surface, can be easily adapted to the instrument by a user, and is simple is to be set, which eliminates the disadvantages of the prior art.

TECHNICAL SOLUTION

This object is achieved by a support device according to claim 1 for arranging a stringed instrument on the floor.

Advantageous embodiments of the invention result from the features of the dependent claims.

The support device for placing a stringed instrument on the floor comprises a foot element, a receiving element and a connecting element, the foot element having a contact surface which is suitable for at least partially resting on a surface, in particular on the floor, and the receiving element being suitable for being attached to a Sting of the stringed instrument to be arranged and/or connected.

The device has a longitudinal axis along the receiving member. The spike is placed on the receiving element along the longitudinal axis. This arrangement is made before playing. This creates absolute freedom of positioning before playing and repositioning while playing. The repositioning is very important because depending on what the player is playing, he has to take different positions to and with the cello and this is made possible by the device.

The device arranged on the instrument can remain on the instrument and it is possible to stow the device with the instrument in the instrument case.

The connecting element is preferably suitable for being connected to the receiving element, and this connection is suitable for producing at least two angular positions and/or pivoting ranges between the receiving element and the foot element. Playing the instrument involves movements and different playing angles. Due to the different angular positions between the receiving element and the foot element, the support device can be adjusted to the required playing angle in order to create a secure and firm connection with the ground, since the foot element rests on the respective surface at all times. As a result, the device does not have to be additionally attached, e.g. to a chair with cords and/or straps, and there is no risk of tripping over cords and straps, which eliminates the risk of accidents.

In a particularly preferred embodiment, the angular position is in a range from 0 to 45 degrees.

The pivoting range of the device lies on one side of a plane that lies along a longitudinal axis of the device. This angular position and the pivoting range largely corresponds to the radius of movement and the playing angle when playing the instrument.

The connecting element advantageously has a ball head which is suitable for being arranged in a receptacle of the base element and for forming a ball head connection with the receptacle.

The device preferably has a sleeve which is suitable for being arranged on the spike. Since the respective spikes of the instruments usually have different geometries with different thicknesses, the sleeve serves as an adapter between the spike and the receiving element. With suitable sleeves, the receiving element can be precisely adapted to all spike tip geometries.

The sleeve consists of a flexible material in order to be able to compensate for different thicknesses of the spikes and to enable a precise arrangement in the receiving element. The flexible, rubber-like sleeve has two other functions in addition to the fitting function. On the one hand the locking function. The connecting element (e.g. a screw) is locked by the sleeve when tightened, so that the connecting element does not come loose due to the vibrations that occur. On the other hand, the function of vibration damping. The acoustic background noises are prevented, which are caused by vibration transmission from a loose metal part to another metal (e.g. by the spiked tip in the receiving element).

In an advantageous manner, the device has a holding structure. The holding structure is suitable for creating a non-slip hold on smooth floors such as stone, parquet etc. without an additional lock. For this purpose, the holding structure can consist of a flexible material that can adapt to the ground and can compensate for any unevenness. On the other hand, the flexible material is also suitable for protecting sensitive floors from possible damage.

The holding structure preferably consists of lamellae. The slats adapt to the ground. The lamellar structure creates adhesion to the floor that does not require any additional fastening/locking, e.g. on a chair using straps and cords. The support structure sticks to any flat surface such as linoleum, wood, marble without damaging it.

In addition, adhesion is maintained because the lamellar structure, aligned at the right angle, is so suitable that even on dusty surfaces it still creates good adhesion because the dust goes between the lamellae. In addition, the lamellas create a vacuum on clean ground, which provides additional grip.

There is significantly more freedom of movement for the user because the combination of high adhesion together with the ball joint guide creates a secure and firm connection with the ground in every required playing angle.

In a particular embodiment of the invention, the receiving element has a locking element that is suitable for locking the spike of the stringed instrument on the receiving element. The spike is inserted into the receiving element and locked with it by the locking element, so that a fixed connection is created. The arrangement is made before playing. This creates absolute freedom of positioning before playing and repositioning during play. This is necessary for the particular way of playing, whereby different positions to and with the cello have to be taken and this is also possible at any time while playing.

The receiving element preferably comprises a magnetic element which is suitable for locking the endpin of the stringed instrument on the receiving element.

In a further embodiment of the invention, the support device also includes an adapter element which is suitable for being arranged on the spike of the instrument. Since there are a plurality of spikes, the adapter element is suitable to be placed on the spike or to replace it altogether in order to connect to the receiving element.

The adapter element preferably comprises a second magnet element which is suitable for establishing a magnetic connection with the magnet element. Due to the large number of different spikes, these are also made of different materials and may not be made of a metallic material that can be attracted by the magnetic element. A magnetic connection can be made with the corresponding spikes via the second magnetic element in the adapter.

DESCRIPTION OF EXEMPLARY EMBODIMENTS

Out of figure 1 a first embodiment of the invention becomes apparent. The individual elements of the support device 1 are shown in an exploded view.

The supporting device 1 comprises a foot element 2, a receiving element 3, a sleeve 4, a connecting element 5 in the form of a ball head screw with a thread 51 and a locking element 6 in the form of a knurled screw. In addition, the endpin 8 of an instrument (eg a cello) is shown. The foot element 2 has a spherical receptacle 21 on its top side 23, which is suitable for receiving the connecting element 5 in the form of a ball-head screw with a thread 51, and on its underside 22 a holding structure 221, e.g. in the form of lamellae (not shown in Fig 1 ).

The support device 1 is assembled as follows: The connecting element 5 is arranged from below (i.e. on the side of the underside 22 with the holding structure 221 of the foot element 2), if necessary with a suitable tool, e.g. an Allen key, in the corresponding receptacle 21 of the foot element 2, so that the thread 51 of the connecting element 5 passes through on the upper side of the base element 2 . The receiving element 3 with an internal thread 31, which corresponds to the thread 51 of the connecting element 5, is screwed to the connecting element 5 from above. The spike 8 of the instrument has a bead 81 . The sleeve 4 is placed on the spike 8 and pushed up to the bead 81. The sleeve 4 connected in this way with the spike 8 is inserted into the receiving element 3 . Since the sleeve 4 consists of a flexible material, constructive differences between different spikes are compensated for, so that a connection that fits exactly is created. This connection is then locked by the locking element 6 in the form of a knurled nut.

The spherical connecting element 5 is movably mounted in relation to the latter due to the arrangement in the spherical receptacle 21 of the foot element 2 . In this way, the position of the connected connecting element 5 and the receiving element 3 can be changed or adjusted by the user and can be adapted to the respective subsurface. If necessary, mobility can be restricted or made more difficult if the threaded connection between the connecting element 5 and the receiving element 3 is tightened with the tool.

figure 2 shows the support device 1 in the assembled state with the inserted spike 8 from the front with a view of the upper side 23 of the foot element 2. The longitudinal axis of the device 1 corresponds to the longitudinal axis connecting the receiving element 3 with the inserted spike 8.

If necessary, a marking (e.g. a manufacturer's logo) is attached to the upper side 23 of the foot element 2, e.g. As a result, the position of the lamellar structure 221 can be made recognizable from above, which is crucial for a secure footing.

The Figures 3 , 3A show the representation of figure 2 in cross section.

Figure 3A is a detailed view of the figure 3 . The connection between the connecting element 5 in the form of the ball head screw and the receiving element 3 can be seen. In addition, the inserted spike 8, which is arranged over the sleeve 4 up to the bead 81 in the receiving element 3, is shown. In addition, the threaded connection between the receiving element 3 with an internal thread 31 and the thread 51 of the connecting element 5 can be seen.

A magnet 71 can also be seen, which is suitable for holding the spike 8 by magnetic force. In addition to the locking element 6 in the form of a knurled nut, the magnet 71 can lock or stabilize the connection of the spike 6 to the receiving element 5 via the sleeve 4 .

The figure 4 shows the support device from the side in cross section. An angled connection between the connecting element 5 and the receiving element 3 can be seen in a sectional view along the axis AA. The inserted spike 8 is arranged in the receiving element 3 via the sleeve 4 up to the bead 81 . The angled position is achieved by arranging the spherical connecting element 5 in the spherical socket 21 of the foot element 2 by forming a ball and socket joint. On the underside 22 of the foot element 2, the holding structure 221 can be seen as a non-slip surface structure in the form of a lamellar structure that runs parallel to a possible marking.

From the Figures 5 to 6A shows a second embodiment 1 'of the invention. According to the figure 5 The support device 1' also includes, like the first embodiment 1, a foot element 2, a receiving element 3, a sleeve 4, and a connecting element 5 in the form of a ball head screw with a thread 51. The foot element 2 is shown in two parts in a lower part 22 with Holding structure 221 and an upper part 23 with spherical socket 21.

Two magnets 71, 72 serve as locking elements. In addition, the supporting device 1' has an adapter 9 which is suitable for receiving the spike 8 (not shown) of an instrument.

The figures 6 , 6A show a detailed view of the connection of the adapter 9 to the connecting element 3. The adapter 9 has a second magnet 72 which is attracted by the first magnet 71. The adapter 9 is used for universal connection (possibly via a threaded connection) with different spikes of an instrument. Since these usually have different shapes and thicknesses, the adapter 9 is used for adjustment. In addition, not all spikes are made of one made of magnetic material, so that in these cases no locking via the magnet 71 can take place.

An additional locking takes place via the locking element 6, but if necessary the further locking element can be dispensed with.

The figure 7 Figure 12 shows a rearward pivoting of the device (together with a sectional view along the axis AA). Starting from a position in which the receiving element 3 is perpendicular to the foot element 2, the spike 8 locked in the receiving element 3 and with the locking element 6 is pivoted by approx. 38 degrees (up to 45 degrees), so that the angle shown of approx Degree between receiving element 3 and foot element 2 is reached.

The figure 8 Figure 12 shows a forward pivoting of the device (together with a sectional view along the axis BB). The spike 8 locked in the receiving element 3 and with the locking element 6 is largely perpendicular to the foot element 2, so that the angle shown of approximately 89.5 degrees between the receiving element 3 and the foot element 2 is achieved.

The Figures 9 to 9C show pivoting in a lateral position. The device 1 is capable of being pivoted sideways in addition to or with the described pivoting fore and aft. Depending on how an instrument is played, lateral pivoting is only required on one side of a plane. The plane lies along the longitudinal axis of the device, which is formed by the spike 8 connected to the receiving element 3 . Therefore, a pivoting range is formed below the cutting plane EE. However, a pivoting range in all directions is also possible.
