Description

The invention relates to a support leg or carrier or holder for percussion Musical instruments, idiophones or membrane phones, comprising at least two telescopically arranged longitudinal sections, which by a clamp or a clamping device in any axial relative position are mutually definable and are operatively connected to a display device hen that of relatively displaceable measuring elements for the respective one push depth or extension length formed between the two lengths is.

A support leg of this type in the form of a tripod tripod is known from US 2,668,682 became known, but for the inclusion or to wear Ka meras or optical instruments. One in operative connection with the relative to one another display device standing on displaceable telescopic measuring members makes it possible to read the respective insertion depth or pull-out length.

An inadequacy of the known tripods, legs or similar supports or holders for devices, in particular percussion musical instruments, such as Idiopho ne, membrane phones or the like is that accurate alignment relatively cumbersome and time-consuming manipulations compared to the ground calls for this because in most cases, multiple actuation of each one  Tension clamp or clamping device is required until the desired Alignment is really achieved.

Such tripods are particularly cumbersome and time-consuming or to operate similar carriers or holders, which are not only telescopic must be genetically adjusted, but also an adjustment require and give around swivel joints directed transversely to their longitudinal axis if necessary, it is also possible to twist the layers around their own longitudinal axes should. Here too, clamps or similar clamping devices must be used loosened and tightened again. So it is necessary in any case nimble to carry out a multitude of adjustment movements and exactly to each other who to vote or adjust.

The invention has for its object a generic leg or to create the same, which, in addition to the length settings, also an exact, reproducible adjustment of swivel joints.

This object is achieved according to the invention in that the free end of the a longitudinal section a transversely aligned to its longitudinal axis Drehge steering with two relatively movable joint parts, which by ei ne clamping device can be determined and a display device with a a marking carrier with scaling is assigned, which is at least least extends over a limited range of rotation angle around the hinge axis.

All that needs to be done now is to ensure that when setting up of the various percussion musical instruments the respective support leg or carrier or holder on the once determined be brought to the individually different but optimal order position of the entire drum kit. All the more so as well a display device is assigned to the joint parts of each swivel joint. On  this way can be on any leg or bracket or holder too whose location, e.g. B. in the inclination and / or direction of rotation, primarily relative to a neighboring percussion musical instrument or the like immediately and be determined and determined with certainty.

Another important training measure exists according to claim 2 still in the fact that the scaling from a starting point about the same rotation areas on opposite sides.

For a correct inclination of the legs or straps or holder it is also still important that according to claim 3 of the clamp Direction on the two joint parts are assigned locking teeth, which either on the adjacent end faces or on each other are complementary conical surfaces of the two joint parts, the division of the Snap teeth preferably on the division of the scaling for display direction is coordinated.

The invention provides for the arrangement of the display devices according to claim 4 and / or assignment to each leg of the bass drum one Drums.

In Figs. 1 to 3 of the drawing, a stator leg 1 is shown as elements in connection with percussion musical in or passes for tripods used. It has an upper length section 2 , which is fastened to a support, for example to a resonator jacket 4 of the bass drum of a drum kit, via a swivel joint 3 , specifically via the joint part 5 , on which the upper length section 2 of the support leg 1 with its joint part 6 attacks. The two joint parts 5 and 6 of the swivel joint 3 are rotatably held together relative to one another about the joint axis 7. The design of the swivel joint 3 is shown in FIG. 5 of the drawing. It can be seen that a pivot bolt firmly anchored in the joint part 5 passes through the joint part 6 and carries on its free end a toggle nut 9 , with the aid of which the joint part 6 can be braced against the joint part 5 . Axle pin 8 and knob nut 9 bil for the swivel 3 a clamp.

A neck 10 of the joint part 5 , which is coaxial with the axis pin 8 , engages centering in the joint part 6 and carries at its free end a spur toothing 11 with which a complementary counter toothing 12 can engage in positive engagement within the joint part 6 . The two teeth 11 and 12 shown in FIG. 5 are preferably designed as so-called te Hirth teeth, which can be brought into positive engagement and held by the axial forces exerted by the knob nut 9 on the axle pin 8 .

About the hinge axis 7 , therefore, the stator leg 1 can be adjusted relative to the support of the swivel joint 3 , that is to say the resonator jacket 4 , over a predetermined angular range in various inclined or inclined positions. In the upper length section 2 of the support leg 1 , a lower length section 13 is guided telescopically, so that the effective length of the support leg 1 can be varied within certain limits as required. The respective length setting of the support leg 1 , i.e. the insertion depth or extension length of the lower length section 13 to the upper length section 2 can be fixed by a tension clamp 14 which sits at the lower end of the upper length section 2 and can be actuated by a toggle nut 15 .

The two telescopically slidably arranged length sections 2 and 13 of the support leg 1 are equipped with a display device 16 , which is formed by two rela tively movable measuring elements, namely a marker carrier 17 and a pointer 18 .

The marker carrier 17 is located on the upper Län gene section 2 of the support leg, while the pointer 18 is connected to the lower length section 13 thereof.

The marker carrier 17 is designed as a provided along the longitudinal edge of a longitudinal slot 19 scaling, while the pointer 18 consists of a radially projecting from the lower longitudinal section 13 and guided in the longitudinal slot 19 Zap fen or the like.

As a scaling or marking carrier 17 edge indentations and / or elevations 20 can be provided distributed along a longitudinal edge of the longitudinal slot 19 , which in addition to the other longitudinal edge of the longitudinal slot 19 different marking symbols 21 , preferably embossed or raised numbers, are assigned.

The display device 16 thus makes it possible to determine the active length of the support leg 1 that is set in each case, so that it can be fixed immediately with the help of the tension clamp 14 in the relevant case.

If all the legs 1 of an object, for example. The bass drum of a drum kit or the tripod for a cymbal are brought to the same effective lengths with the aid of the display devices 16 , it is ensured that the instrument or device in question is in the correct alignment position with respect to its support surface , e.g. the floor.

From Fig. 3 of the drawing it can be seen that the upper Län gene section 2 of the support leg 1 has approximately a C-shaped hollow cross section, in which the full circular cross section of the lower length section 13 is added.

The legs 1 can be designed to allow a variation of their lower end. At the lower end of its lower length section 13 , the legs 1 have an adjusting thread 23 a, which has a thickened foot part 22 , for. B. made of hard rubber, with a matching Innenge thread. A counter nut 23 b is used to fix the position of the thickened foot part 22 on the adjusting thread 23 a. The lower end at the lower length section 13 of each leg ends in a tip 24 , which, depending on the setting of the thickened foot part 22, either lies opposite its lower end or is above it, as can be seen in FIGS. 1 and 2 , With the tip 24 of the length section 13 lying behind, only the thickened foot part 22 serves to support the base of the respective support leg.

In the illustrated in FIGS. 1 to 3 Ausführungsbei a stator leg game 1, the relative position of the two lengths 2 and 13 and so that the effective length of the STAs coarse one 1 is effected solely with the aid of the tension clamp 14 thus by tightening the clamping nut 15 after about On the display device 16, the desired length dimension has been set exactly beforehand. In Fig. 4, however, a display device 16 is shown, which differs from the display device 16 according to FIGS . 1 and 2 in that the longitudinal slot 19 in the region of each individual Randein notch or increase of the marking carrier 17 has a circular section-shaped slot extension 25 ,

Serving as a pointer 18, in cross section circular pin is in this case axially movable and cushioned in a receptacle on the lower length section 13 and can thereby form a locking member that can engage with each of the edge notches 20 of the longitudinal slot 19 in locking engagement ge. To disengage the locking member serving as pointer 18 pin is pressed back only by finger pressure ent against the spring force when a Längenver position of the support leg 1 is necessary. In this case, each length adjustment of the stand leg is first fixed automatically and then the indented locking member is protected against overstressing by pulling the tension clamp 14 .

It is also conceivable to disengage the pointer 18 formed as a spring-loaded locking member from the rear of the lower Längenab section 13 via a suitable handle by exerting a tensile force if a length adjustment of the support leg 1 is desired.

In Fig. 1 of the drawing it can still be seen that the two joint parts 5 and 6 of the swivel joint 3 is associated with a display device 26 which extends at least over a limited range of rotation angles, for example of 180 ° around the joint axis 7 . It will on the one hand fixed by a at the end face of the hinge portion 6, preferably integrally connected label carrier 27 as well as a raised from the hinge part 3 and formed along the marking carrier 27 movable pointer 28th

The marker carrier 27 is designed as a scale extending over a semicircle, which is formed by Einkerbun conditions or surveys. The pointer 28 is attached to the circumferential surface of the hinge part 6 and is just if formed by a notch or an elevation.

The scaling 27 provided as a marking carrier is here also different marking symbols 29 , e.g. B. an embossed or raised digits, assigned so that they extend from the center of the scale to the left and to the right over a same arc section of, for example. 90 ° of the marker carrier 27 away.

With the help of the display device 26 , the inclination or inclined position of each support leg 1 relative to its fastening base, for example the resonator jacket 4 , can be precisely controlled in two different directions and, if necessary, via the toggle nut 9 and the spur toothing 11 and the counter toothing 12 with a positive fit. Here too, the matching angle setting of a plurality of stand legs 1 is considerably simplified by the display device 26 .

In Fig. 6 of the drawing a different in its design from the rotary joint according to FIG. 3 rotary joint 3 is shown. Also here with the fixed hinge part 5 the trained on the obe ren length section 2 of the support leg 1 Ge steering part 6 via an axle bolt 8 and a gag nut 9 in such a way that a relative rotation of the two hinge parts 5 and 6 about the hinge axis 7 can be made possible , On the other hand, however, the two joint parts 5 and 6 can also be fixed in a positive manner in a large number of different rotational angle positions relative to one another. For this purpose, the joint part 5 on its neck 10 has a conical bearing projection 30 , which is assigned a complementary conical counter surface 31 of the joint part 6 . The conical surface of the conical bearing boss 30 is provided with a toothing 32 , to which a conical counter toothing 33 in the joint part 6 fits.

The advantage of the conically interlocking teeth 32 and 33 of the swivel joint 3 according to FIG. 6 is that they are also in a positive positive engagement with one another when the clamping device formed by the axle bolt 8 and the gag nut 9 loosens in an undesirable manner. The swivel joint 3 according to FIG. 6 thus has with its conical engagement toothings 32 and 33 a higher grip security than the swivel joint 3 according to FIG. 5 with its spur toothings 11 and 12 .

While the legs 1 in the type described above are mainly used for the direct support of the large drum of a drum by attacking or attaching to their resonator jacket 4 , Fig. 7 of the drawing shows a legs 41 equipped at its lower end with three stands 41 Tripod 42 , as it is used regularly as a carrier or holder for other percussion musical instruments of a drum kit, i.e. both Idiophone and Membrano phone.

The tripod 42 has thereby a tubular guide column 43, which evenly distributed at its lower end carries three circumferentially arranged and radially projecting bearing lugs 44, in each of which one end of a swivel arm is articulated 45th The other end of each swivel arm 45 is in turn connected to one of the legs 41 in an articulated connection, in each case at a point which, based on the total length of the legs 41, has certain spacing ratios to both ends of the leg 41 .

While the lower end of each support leg 41 is equipped with a thickened foot part 46 , for example made of hard rubber, the upper end of the same is connected in an articulated manner to a sliding sleeve 47 which encloses the outer circumference of the tubular guide column 43 in a longitudinally movable manner.

Each support leg 41 with the associated swivel arm 45 is preferably made relative to the guide column 43 in the manner of a so-called elliptical link, which has the advantage that the distance of the lower end of the guide column 43 from the floor does not change when the three support feet 41 are in a different spread position. Therefore, it is pos sible to vary the spreading position of the stand feet 41 relative to the guide column 43 as a function of different set-up conditions.

Each spread position of the stand legs 41 relative to the guide column 43 can be fixed by the fact that the sliding sleeve 47 can be fixed by means of a mounting clamp 48 on the guide column 43 of the stand 42nd

Also on the upper end of the guide column 43 of the stand 42 , a clamping device 49 in the form of a tension clamp is installed. The clamping device 49 can be seen on a larger scale in FIG. 8 of the drawing, while the sliding sleeve 47 with tensioning clamp 48 can be seen on a larger scale in FIG. 9.

In the tubular guide column 43 , a tubular sliding column 50 is in turn received, which can be fixed by means of the clamping device 49 in any relative sliding position to the guide column 43 . The upper end of the sliding column 50 also carries a clamping device 49 and is designed for the axially displaceable receiving of a further sliding column 51 , the axial sliding position of which relative to the sliding column 50 can be determined by the clamping device 49 . The upper end of the sliding column 51 is equipped with a rotary joint 52 , which is at least similar in its design and mode of operation to the rotary joint 3 according to FIGS. 1, 2 and 5 of the drawing. It thus has a fixed upper end of the sliding column 51 arranged joint part 53 and this movable joint member 54, said hinge parts 53 and 54 or are free gebbar by a mounting clamp 55 against each other can be fixed to the adjustment, by a wing nut is actuated, such as the is also the case with the swivel according to FIGS. 1, 2 and 5. The swivel joint 52 with its joint parts 53 and 54 and the tensioning clamp 55 can be seen on a larger scale in FIG. 12 of the drawing. It serves for the angularly displaceable mounting of an articulated support 56 on the upper end of the sliding column 51 .

In Fig. 10 of the drawing it is shown that the upper end of the sliding column 50 can also carry a fixed head piece 60 instead of a clamping device 49 , which protrudes transversely to the longitudinal direction of the sliding column 50 on both sides. An articulated arm or an articulated support 61 is held in each of the two projections of the head piece 60 , specifically with an arm section 62 , at the upper end of which a further arm section 64 is connected via a swivel joint 63 .

The swivel joint 63 corresponds in terms of its design and effectiveness to the swivel joint 52 according to FIGS. 7 and 12 and is therefore explained below with reference to FIG. 12.

The arm section 42 of each articulated arm or each articulated support 61 is held in the head piece by means of a special clamping device 65 , which is adjustable both in length and rotation, and a corresponding clamping device 65 is also assigned to the arm section 64 of each articulated arm or each articulated support 61 . The design of this clamping device 65 results from FIG. 11 of the drawing.

With regard to the apparent from FIGS . 10 and 11 configuration of a carrier or holder, it should also be mentioned here that the sliding column 50 does not necessarily have to be arranged in the guide column 43 of a tripod 42 , but rather with the aid of a clamping device 65 from FIG . 11 apparent design type can be directly on the Resonatormantel 4 of the large drum mounted a drum set, if this appears advantageous or desirable.

The clamping device 65 on the arm section 64 of each articulated arm or each joint support 61 can in turn be connected to the resonator jacket of small drums of a drum kit, for example the so-called tom-toms. With the upper end of either the sliding column 50 or a further sliding column 51 of the stand 42 , a rotary joint 66 can also be firmly connected, as can be seen in FIG. 13 of the drawing.

From Fig. 8 of the drawing it can be seen that the Klemmvor device 49 on the upper end of the guide column 43 cooperates with the slide column 50 guided in it via two different display devices 67 and 68 . Corresponding display devices 67 and 68 are also assigned to the Klemmvor device 49 on the sliding column 50 to cooperate with the second sliding column 51 according to FIG. 7. The display device 67 is designed so that it responds to the longitudinal displacement of the sliding column 50 or 51 in the guide column 43 or in the sliding column 50 . It therefore makes it possible to exactly determine the respective insertion depth or extension length of the sliding column 50 relative to the guide column 43 or the sliding column 51 relative to the sliding column 50 .

The display device 68 , however, is provided between the clamping device 49 and the sliding column 50 or between the clamping device 49 and the sliding column 51 , so that a rotation of the sliding column 50 about its longitudinal axis relative to the guide column 43 and also a rotation of the sliding column 51 relative to its longitudinal axis to the sliding column 50 can be determined exactly.

The display device 67 has, as cooperating measuring elements, on the one hand as a fixed pointer 69 the upper end edge of the clamping device 49 and on the other hand a scale 70 on the sliding column 50 or 51 . The latter is formed by a plurality of in the longitudinal direction of the sliding column 50 or 51 at predetermined intervals one behind the other marks 71 , for example. Perimeter marks, which in turn have special characteristics, eg. B. letters and / or numbers are assigned.

The display device 68 has as a pointer an uninterrupted and straight line in the longitudinal direction of the sliding column 50 or 51 marking line 73 , while the clamping device 49 carries at its upper end a circumferentially arranged scale 74 which marks by additional markings, for example numbers or letters, is added.

With the aid of the display device 67 , the relative longitudinal position between the sliding column 50 or 51 and the clamping device 49 can be determined, while this is the case for the relative rotational position with the aid of the display device 68 .

From Fig. 9 of the drawing it can be seen that a display device 75 is also arranged between the sliding sleeve 47 and the guide column 43 of the stand 42 . It serves to determine different spreading positions of the three stand feet 41 relative to the guide column 43 of the stand 42 . The upper edge of the sliding sleeve 47 serves as a pointer of this display device 75 , which in turn can be fixed on the guide column 43 with the aid of the tensioning clamp 48 . By contrast, the measuring element of the display device 75 is a scale, which consists of a large number of line markings which are applied in the longitudinal direction of the guide column 43 to the outer circumference thereof and each have fixed distances from one another. These line markings 77 can also be assigned special additional markings 78 , for example numbers.

From Fig. 11 of the drawing it can be seen that in the carrier or holder shown in Fig. 10 of the drawing, each clamp 65 and the associated arm section 62 or 64 of the articulated arms or articulated supports 61 are again assigned two display devices 79 and 80 , which correspond in their arrangement and mode of operation to the display devices 67 and 68 according to FIG. 8 and to the extent that they no longer need to be explained in addition. Therefore, it should only be mentioned here that with the display device 79 longitudinal displacements between the clamping devices 65 and the arm portions 62 and 64 of the articulated arms or articulated supports 61 can be determined, while the display device 80 is useful for determining rotational displacements of the same parts about their common longitudinal axis ,

A special feature of the clamping devices 65 , as they are used in the carrier or holder according to FIG. 10, can still be seen from FIG. 11. According to this, each clamping device. a clamp 81 , which can be fixed with the help of a clamping screw 82 in any rotational and longitudinal position, for example on the Armab 62 or the arm section 64 of the articulated arm or the articulated support 61 . On the other hand, it also has a clamping sleeve 83 , which can be easily operated manually using a wing nut. The clamp bracket 81 carries at its end facing the clamping sleeve 83 a projection or cam 85 , while the clamping sleeve 83 in its end surface facing the clamping bracket 81 holds a projection 86 complementary to the projection or cam 85 . Projection or cam 85 and recess 86 can be brought into and out of clutch engagement with one another by corresponding axial displacement of the clamping sleeve 83 , in which case not only a very specific axial position but also a very specific rotational position of the clamping sleeve 83 for the respective arm section 62 or 64 the articulated arm or the articulated support 61 is fixed.

In Fig. 12 of the drawing it can be seen that the rotary joints 52 of FIG. 7 and 63 of FIG. 10 have a special display device 87 . This consists, for example, of a pointer 88 arranged on the peripheral surface of the one joint part, for example the joint part 53 , and a scale 89 provided on the peripheral surface of the other joint part, for example the joint part 54 . With the help of this device 87 either the inclination position of the articulated support 56 relative to the sliding column 51 according to FIG. 7 or the inclined position of the arm section 64 relative to the arm section 62 of the articulated arms or articulated supports 61 according to FIG. 10 can be determined. The basic position of the respective swivel joint 52 or 63 can be the extended position, but also any other angular position of the parts coupled by the swivel joint.

The swivel joint 66 shown in FIG. 13 of the drawing can be implemented in a manner corresponding to the swivel joint 3 according to FIG. 1 of the drawing. That is, the scale 90 is plotted on the flat end face of one joint part 91 , while the other joint part 92 carries the pointer 93 .

Finally, in FIG. 14 of the drawing, a lateral section of the standing drum 94 of a drum set can be seen, with the resonator jacket of which several stator legs 96 are connected via a clamping device 95 . A display device 97 is also provided between each support leg 96 and each clamping device 95 , which includes a pointer 98 on the clamping device 95 and a scale 99 on each support leg 96 . The display device 97 makes it possible to set the stand drum 94 quickly and precisely from the ground, on which the legs 96 are supported.
