ADJUSTABLE ENDPIN FOR THE CELLO

Abstract: In a cello or similar instrument there is a fitting for an endpin. The endpin serves to give the instrument a desired position for a musician playing it. According to the invention the endpin (15) is insertable into the instrument (11) through the fitting (14) hinged in the fitting (14) and lockable in position.

Description: AJUSTABLE ENDPIN FOR THE CELLO 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 on gives it 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 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 longi¬ tudinal direction through a fitting in the wall of the in¬ strument. Before playing the musician pulls out the endpin and locks it with a set-screw in a desiredposition. However, it has turned out that the musicians 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 poing in the vertical plane through that line but closer to the vertical line through the centre of gravity. Then the instrument will rest on the musician with a certain pressure without burdening him or her to much. Instead an curved or bent endpin is used, which can be attached to a fitting on a cello. This endpin can not be i •nserted into the intstrument but is detachably arranged. It is troublesome to handle an separate endpin which further can get lost during transport. Disclosure of Invention The present invention is intended to solve the above proble and an arrangement according to the invention for this pur¬ pose is mainly characterized therein, that the endpin is arranged insertable into the instrument through the fitting and hinged in the fitting when pulled out in which position it is lockable in position. Brief Description of Drawings In the following the invention will be described more in detail with reference to an arrangement shown in the drawin The Fig. 1 shows a musician with a cello having a prior art of an endpin. The Fig. 2 is a corresponding view of a musician with a cello having an endpin according to the invention. The Fig. 3 is a perspective view of a cello having the new endpin, but with the prior art an endpin indicated. The Fig. 4 is a section in a larger scale throug the part of the cello in Fig. 3 where the endpin is arrange Best Mode of Carrying out the invention From the Figures 1, 2 and 3 it appears that the prior art of an endpin 10, which is insertable into the instrument 11 has a considerable length. Still it is not satisfactory i.a. because the resting point 12 on the floor is not situated a 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 centre of gravity of the instrument when it is played on. The prior art of the endpin 10 is insertable in a fitting 14 and lockable in inserted or pulled out position by a set- screw. 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 of which 18 being insertable in the other one 17 and lockable in a desired position with a set-- " -. screw 19. In the lower part of the instrument at the inner side a clamp 20 is arranged a block of wood, in which there is a slightly conical hole 21. In the prior art 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 in¬ vention a sleeve 22 being conical outside and cylindrical inside is arranged in the hole 21 in the clamp 20. The hole 21 has different diameters in different instruments. According to the invention when mounting an endpin a conical sleeve 22 is inserted into the clamp and a possibly projectin part is cut away. Thereafter a fitting 23 can be arranged wit its cylindrical part 24 inside the adjusted sleeve 22. Before this is done, however, the endpin 15 is inserted into the fitting from the inner side thereof but without the set-screw 19, which is mounted after the endpin.has been inserted into the fitting. When the said parts have been mounted on th instrument a tension band 25 is placed in a groove 26 around the fitting 23, up over the edge of the instrument to a string holder 27. From this holder strings 28 pass over a bridge 29 to tuning screws 30 at the head of the instrument. In order for the fitting 23 to give the desired effect, beside the through, cylindrical hole 31 it has a recess 32 (see Fig. 4)., which makes it possible to turn or articulate the endpin in about a vertical plane so that the free end 13 of the end¬ pin will be situated behind the intersection 12 between the floor and a centre line in the longitudinal direction of the ____________ ' instrument. In a transversal hole 33 is a cylindrical sleeve 34 made to turn. It has a hole 35 intended for the endpin 15. The hole 35 at the inner end is widened to give room for the ring 16 on. the endpin 15. With a set-screw 36 the sleeve 34 is lockable in place. The load of the instrument on the end¬ pin is transferred to the endpin thereby that the inner end of the endpin abuts the fitting inside the hole 33. OMPI
