BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to an arrangement in a cello, or a similar instrument, having a fitting for an endpin which, when the instrument is played, remains a fixed position above the floor.
BACKGROUND ART
It is common in the art to use an endpin on a cello. The instrument itself is voluminous and requires a bulky case for storing and as protection in transport. Therefore an endpin which is permanently fixed to the instrument is not used. Such an endpin also would have the drawback that different musicians playing the same instrument at different occasions could be forced to use the instrument with the same endpin having a predetermined size and shape. Instead the endpin has been made insertable into the instrument in its longitudinal direction through a fitting in the wall of the instrument. Before playing the misicain pulls out the endpin and locks it with a set-screw in a desired position. However, it has turned out that the misicians are not in favour of having the resting point on the floor situated on a line in the longitudinal direction through the instrument. They want the resting point to be located in the vertical plane through that line but closer to the vertical line through the center of gravity. Then the instrument will rest on the musician with a certain pressure, without burdening him or her too much. Instead a curved or bent endpin is used, which can be attached to a fitting on a cello. This endpin can not be inserted into the instrument but is detachably arranged. It is troublesome to handle a separate endpin which furthermore may get lost during transport.
DISCLOSURE OF INVENTION
The present invention is intended to solve the above problem and an arrangement according to the invention for this purpose is mainly characterized therein, whereby the endpin is arranged to be insertable into the instrument through the fitting and hinged in the fitting when pulled out. In that position it is locked.
BRIEF DESCRIPTION OF DRAWINGS
In the following description the invention will be described more in detail with reference to an arrangement shown in the drawings in which:
FIG. 1 shows a musician with a cello having a prior art endpin construction.
FIG. 2 is a corresponding view of a musician with a cello having an endpin according to the invention.
FIG. 3 is a perspective view of a cello having the new endpin, but with the prior art endpin indicated.
FIG. 4 is a section in a larger scale through the part of the cello in FIG. 3 where the endpin of the invention is arranged.
BEST MODE OF CARRYING OUT THE INVENTION
From the FIGS. 1, 2 and 3 it appears that the prior art shows an endpin 10, which is insertable into the instrument 11 and has a considerable length. Still it is not satisfactory, because the resting point 12 on the floor is not situated at the place where it is desired. Further it appears from the Figures that with an arrangement according to the invention it is possible in a simple way to obtain a resting point 13 on the floor closer to the instrument or better expressed closer to the vertical line through the center of gravity of the instrument when it is played.
The prior art construction of the endpin 10 is a device that is insertable in a fitting 14 and lockable in an inserted or pulled out position by a setscrew.
The inner end of the endpin 15 according to the invention has an outside abutment ring 16 (FIG. 4). The endpin 15 has two parts 17, 18, one part 18 being insertable in the other part 17 and lockable in a desired position with a setscrew 19. In the lower part of the instrument at the inner side a clamp 20 is in the form of a block of wood, in which there is a slightly conical hole 21. In the prior art construction a conical part of a fitting serving as a string holder was inserted here. Such fittings are also known having a through hole in which an endpin was inserted. According to the present invention, however a sleeve 22 being conical outside and cylindrical inside is arranged in the hole 21 in the clamp 20. The hole 21 has different diamet
