    The invention relates to an end-pin holder for a musical instrument that is played from a sitting position in a chair, and said musical instrument has an end-pin.
    BACKGROUND
    The violoncello or cello is the bass member of the violin family and is tuned an octave below the violin. These instruments are large in size and hence played in a sitting position.These are fitted with a projecting end-pin that engages the floor so that the instrument may be held in from an almost vertical position to 45 degrees. Among other instruments also having end-pins or end-rests and are played in a sitting position is for example the double bass.
    The end-pin is a component that makes contact with the floor to support the instrument's weight. It is made of metal, carbon fibre, or some other material such as wood, and is extensible from the bottom of the instrument, and secured there with a thumbscrew or similar arrangement. End-pins are tipped with a point to stick to the floor, and the tip is sometimes capped with black rubber or similar so as not to damage the floor and to provide friction to keep the instrument in place. Generally, end-pins are parallel to the longitudinal axis of the instrument, but some cellists and bassists fit their instruments with a Tortelier-style end-pin, which angles more towards the floor, improving mobility at the expense of stability. Also, some endpins have a secondary extension. The end-pin also may have notches cut in it, allowing it to have extra holding strength at these points. This design is particularly common on string basses and beginner-level cellos. The former often require these because of their greater weight.
    There are some problems associated with the end-pin. The pressure exerted on the instrument may cause the end-pin to slip on the floor which may cause accidents or at the very least prove a distraction to the musician. Pointed end-pins can cause damage to the floor. Especially susceptible to damage are tile and wooden floorings. Many floors bear evidence of this in the form of a multitude of small holes or chips. To prevent this, rubber tips, suction cups or end-pin holders with an adhesive tip facing the floor are used. However, these do not work on carpets. The end-pin may punch a hole in the carpet or cause it to tear. Also, it is possible that the sharp end-pin penetrates the rubber tip or a similar stopper. The end-pin holder can also be a strap or a string of which one end attaches to the end-pin and the other end is a loop or similar arrangement that can be attached to the musi cian’s chair. The problem with these kinds of end-pin holders is that the string is prone to entanglement. Also, it is practically impossible for a musician to change his or hers playing position during the concert.
    Patent publication US 4018129 discloses an end-pin holder for cellos and other string instruments. The end-pin holder is a box-like structure having four legs in the corners of the structure. The main goal of this end-pin holder is to reinforce the sounds produced by the instrument and to improve its playing qualities. According to the publication, the end-pin of a string instrument, though necessary to enable playing from a sitting position, has a negative effect on the playing qualities of the instrument in that it acts as an acoustic leakage path between the instrument and the ground and thereby transmits vibrations thereto. This leakage dampens and otherwise impairs the tonal characteristics of the instrument. However, the described end-pin holder is not applicable all kinds of surfaces. It may not keep the instrument in its place during play. Also, it demands exact positioning before use. In addition, the publication hints that it is difficult to predetermine the optimum thickness of the top and back plates that will impart the desired resonance frequencies to the body of the instrument i.e. it is possible that the end-pin holder may have an undesirable effect on the sound of the instrument.
    BRIEF DESCRIPTION

    DESCRIPTIONS OF THE FIGURES
    In the following, the invention is described in detail. The description refers to the accompanying drawings, in which
    Figure 1 shows an example of an embodiment of an end-pin holder, and
    Figure 2 shows a folding process of a second embodiment of an end-pin holder.
    DETAILED DESCRIPTIONS OF THE FIGURES
    The embodiments in the following description are given as examples only and someone skilled in the art can carry out the basic idea of the invention also in some other way than what is described in the description. Though the description may refer to a certain embodiment or embodiments in several places, this does not mean that the reference would be directed towards only one described embodiment or that the described characteristic would be usable only in one described embodiment. The individual characteristics of two or more embodiments may be combined and new embodiments of the invention may thus be provided.
    Figure 1 shows an example of an embodiment of an end-pin holder 100.There is an instrument 119 having an end-pin that is supported by the end-pin holder. In the figure are also some parts of a chair 120 that the musician of the instrument is sitting on. In the figure the end-pin holder is ready for use and it is examined from above.
    In this example the end-pin holder 100 comprises five parts that are fixed to each other to form a foldable structure. The parts are a first part of the support part 101, a second part of the support part 102, a middle part 103, a first side part 104 and a second side part 106. The first part of the support part and the second part of the support part form together a support part 121. The parts are plate-like constructs and they have a top surface and a bottom surface. When the end-pin holder is in use, the bottom surfaces of the parts face the floor or some other surface and the top surfaces face upward. Of course, when transporting or folding the end-pin holder, the surfaces could face different directions. The material of the parts can be for example wood, plastic, carbon fibre or similar or some combination thereof. Advantageously the chosen material does not resonate or otherwise distort the sound of the instrument 119. The parts have first ends and seconds ends and sides. The ends are named in a way that when the end-pin holder is in use, the first ends are pointing away from the musician and second ends are pointing toward the musician. The first sides of the parts are left sides of the parts from the musician’s vantage point and the second sides of the parts are right sides of the parts from the musician’s vantage point.
    The first part of the support part 101 has a first end of the first part of the support part 113 and a second end of the first part of the support part 114. The first end of the first part of the support part is also the first end of the support part 121. The second part of the support part 102 has a first end of the second part of the support part 115 and a second end of the first part of the support part 116. The second end of the second part of the support part is also the second end of the support part 121.
    On the support part 121 is a support structure 112. The support structure is for receiving and holding the end-pin of the instrument 119. The support structure is configured to have several shapes for placing the instrument in different positions in relation to the musician. In this embodiment the shapes of the support structure are a multitude of pits on the top surface of the support part. There are pits on the first part of the support part 101 and they extend to the second part of the support part 102. Advantageously the pits or other shapes are placed in some geometrical pattern so as to make it easy for the musician to find the right position for the instrument. The favourite pit can be marked by a marking arrangement. This can be for example a sleeve or a similar removable appendage. The support structure can also comprise grooves or holes or similar shapes. It is essential that these shapes can receive the end-pin and provide support for it so the instrument stays in the desired position. Advantageously the shapes are such that moving the end-pin is easy but they still reliably secure the instrument.
    Between the first part of the support part 101 and the second part of the support part 102 is a fourth hinge arrangement 111. The first part of the support part can be folded over the second part of the support part in such a way that the top surfaces of both parts are facing each other.
    The middle part 103has a first end of the middle part 117, a second end of the middle part 118, a first side of the middle part 123 and a second side of the middle part 124. The middle part is fixed to the support part 121 with a third hinge arrangement 110. In this embodiment the third hinge arrangement is a double hinge. There is a first barrel pivot and a second barrel pivot and a hinge plate between them. The third hinge arrangement is fixed in such a way that the first barrel pivot is on the first end of the middle part 117 and the second barrel pivot is on the second end of the support part 116 (i.e. the second end of the second part of the support part). The middle part rotates in relation to the hinge plate and the support part rotates in relation to the hinge plate. Due to the hinge plate there is a gap 122 between the middle part and the support part. The width of the gap depends on how the end-pin holder is folded. Its width equals at least the thickness of some part. When the end-pin holder is folded i.e. the parts are folded over the middle part, the third hinge arrangement provides necessary spacing between the support part and the top surface of the middle part. In one embodiment the side parts are folded over the middle part and the support part is in turn folded over them. There is also an embodiment where the first part of the support part 101 is folded over the second part of the support part 102 and both are then folded over the middle part and then the side parts are folded over the support part. The hinge arrangements can be conventional metal or plastic hinges but naturally they can be contructions made of cloth or leather or similar material. Essential is that the hinge arrangements allow parts to move in relation to each other.
    The first side part 104 has two sides, a first end of the first side part and a second end of the first side part. On the first side part is a first stopping arrangement 105. The stopping arrangement serves to prevent the chair 120, that is placed on the end-pin holder 100, from sliding off the second end of the first side part. The stopping arrangement in this embodiment is a wall-like structure on the second end of the first side part. Naturally, there are many embodiments for the stopping arrangement. Of course, the stopping arrangement could be implemented by selecting a material for the side part that provides sufficient friction between the chair and the side part for so as to prevent undesirable movement when the end-pin holder is in use. In some embodiments the stopping arrangement is configured to fit some shaping for example on the middle part when the end-pin holder is folded. Between the first side part and the middle part is a first hinge arrangement 108. The first hinge arrangement is fixed to the second side of the first side part and the first side of the middle part 123. The first side part can be folded over the middle part. In some embodiments the first hinge arrangement is a double hinge.
    The second side part 106 has two sides, a first end of the second side part and a second end of the second side part. The second side part has a second stopping arrangement 107. The second stopping arrangement is similar to the first stopping arrangement. Between the second side part and the middle part is a second hinge arrangement 109. The second hinge arrangement is fixed to the first side of the second side part and the second side of the middle part 124. The second side part can be folded over the middle part. In some embodiments the second hinge arrangement is a double hinge.
    In some embodiments there is some stopping arrangements on the middle part 103.
    Hinge arrangements are fixed onto the top surfaces of the parts or in such a way that the bottom surfaces of the parts form a flat surface i.e. there are no protrusions under the end-pin holder 100 when it is prepared for use.
    There are embodiments where the length of the support part, i.e. the distance from the first end to the second end, or the length of the first part of the support part 101 or the length of the second part 102 of the support part approximately equals the length of the middle part 103. This prevents the support part from extending over the second end of the middle part 118 and thus makes moving and storing the folded end-pin holder easier. In this example the length of the whole support part is twice the length of the middle part 103.
    When the end-pin holder 100 is in a folded position i.e. the other parts are folded over the middle part 103, there is a sign on the bottom surface of the part that is topmost. The sign indicates the position in which the folded end-pin holder is to be placed in order to make the upper surfaces face away from the floor or a similar surface when the folded end-pin holder is opened for use.
    When preparing the end-pin holder 100 for use it is placed on a surface and opened if it is still folded. The chair 120 is placed on the end-pin holder in such a way that some parts of the chair rest on some part of the end-pin holder. Those parts are the side parts and the middle part. When the musician sits on the chair the parts of the chair placed on the end-pin holder apply pressure on the end-pin holder, holding it in place. To enhance this effect the stopping arrangements can further hold the chair stationary. The sitting musician then places the end-pin of the instrument into the support structure 112 to achieve a position that the musician considers optimal.
    Figure 2 shows a second example of an embodiment of an end-pin holder 200 and the process of folding the end-pin holder. The end-pin holder is seen from above. The end-pin holder comprises a first part of the support part 201, a second part of the support part 202, a middle part 203, a first side part 204 and a second side part 205. Four hinge arrangements are used here for fixing the parts to each other. The first part of the support part and the second part of the support part are fixed to each other. The first side part is fixed to the middle part. The second side part is also fixed to the middle part. The second part of the support part is fixed to the middle part and between them is a gap 206. The fixing arrangement is practically similar to that was described in the embodiment of figure 1.
    In figure 2a the end-pin holder 200 is ready for use. The top surfaces of the parts are visible.
    In figure 2b the first side part 204 is folded over the middle part 203. In figure 2c the second side part 205 is folded both over the middle part and the first side part.
    In figure 2d the first part of the support part 201 is folded over the second part of the support part 202, leaving a wholly folded support part. The hinge arrangement between the support part and the middle part 203 is configured in such a way that there is a gap 206. The hinge arrangement could be a double hinge as was described earlier. The width of the gap in this embodiment equals the combined thickness of the first side part 204 and the second side part 205. Due to this, when the folded support part is folded over the middle part, the first side part and the second side part as shown in figure 2e, the support part lays smoothly over them. The end-pin holder 200 is now in a completely folded configuration. If there is a sign that indicates the upward position for the folded end-pin holder, it is in this embodiment on the bottom surface of the second part of the support part 202.
    Some advantageous embodiments of the method and device according to the invention have been described above. The invention is however not limited to the embodiments described above, but the inventive idea can be applied in numerous ways within the scope of the claims.
