Rapid fastener

Quick mounting

The invention relates to a fixture, which was created for the quick assembly and disassembly of basins and cymbals on a cymbal stand o.

The invention is based on the main task of creating a cymbal / cymbal attachment from a few components and yet for different, customary thread on cymbal stands, which can be attached or released by the drummer or another person within a short time.

This object is achieved in that instead of the conventional wing nut a mainly made of plastic fastening was created, which presses on a cone, two retaining rubbers to the mounting thread of a cymbal stand, (see functional description). By means of this construction according to the invention, it is possible to use only one quick-fastening type for the different thread types of the cymbal stands without damaging the thread of the stand.

Preferably, the surface of the quick attachment on recessed grips, by which the handling of the attachment is much easier. Thus, when attached, by one-handed turn on the lower part of the quick attachment continue to be the damping of the pelvis steplessly adjusted. Due to the fact that the retaining rubbers of the quick-release clamp on the cymbal stand thread, a counter-wrenching against the usual wing nut, not required.

The invention is also characterized by the fact that the damper felt for the damping of the pelvis / cymbal is embedded in a part with in the vorgesehenden depression of the quick attachment. Moving the damper felt from the center of the cymbal stand thread is therefore no longer possible. Consistent, pre-desired damping properties are retained.

The quick attachment is further characterized by the fact that it has a conical upwardly tapered shape. This has in addition to the visually well-adapted form nor the property of the invention that blows from the drummer, which are directed to the pelvic bell of a cymbal / cymbal, even then meet their desired goal, if they and that often occurs at faster playing, otherwise the Wing nut or washer. Due to the tapered shape of the quick attachment of the drum stick can bounce and thereby still reach the bell.

Another advantage of the invention is that the otherwise consisting of 4 items (damper felt, Unterleyscheibe, lock nut and wing nut) existing pelvic attachment by the invention only from a handy, easy-to-use part.

The application of the invention is illustrated in the drawing and will be described in more detail below. FIG. 1 shows an exploded view of the quick fastening with indicated basin / cymbal and cymbal stand thread. FIG.

The invention quick attachment for cymbals / cymbals to cymbal stands with different mounting threads, consisting of: Fig. 1 conical cover (1) with the recessed grips (13), the internal thread (8) and the circular guide groove (11) on the conical bottom.

Truncated cone-shaped lower part (2) with tapered inner bore (6) having two opposite, parallel surfaces, the recessed grips (13a) and the circular retaining edge (7) for the damper felt and the circular guide spring (lla) at the top.

Clamping screw (3) made of elastic material, with external thread, (8a) the recessed clamping slot (9) in the tapered clamping element, (6a) which also has two parallel sides. A through bore (12) in which the grooves for the retaining rubbers (4) are also show the clamping screw.

Holding rubbers (4) located in the through hole (12) of the clamping screw (3).

Damper felt (5) sitting in the retaining edge (7) of the lower part (2).

Function of the quick attachment: If the conical cover (1) and the frusto-conical lower part (2) in the assembled state, guided by the Führungsnut- and spring (11, lla), rotated against each other, the clamping screw (3) by the threads (8 , 8a), depending on the direction of rotation, moved vertically upwards or downwards. (Fig. 3) If the cover (1) is rotated in a clockwise direction against the lower part (2), the clamping screw (3) with its tapered clamping element (6a) pulls against the through hole (6) of the lower part (2). By the clamping slot (9) is made possible that the clamping screw (3) with its conical clamping element (6a) can move further into the lower part (2). Thus, triggered by the conically shaped through hole (6) and the corresponding counterpart (6a), the clamping screw (3) and thus the retaining rubbers (4) in the through hole (12) against the mounting screw (14) of the cymbal stand o. The like pressed.

The release of the quick attachment of the mounting screw (14) on the cymbal stand or the like. happens in reverse order with the clamping screw (3) again spread apart due to their elastic material and the fastening screw (14) is free.

As can be clearly seen in Fig. 2, the conically shaped through hole (6) and the tapered clamping element (6a) of the clamping screw (3), not formed as a continuous round truncated cone, but on two opposite sides in parallel. As a result, the clamping screw (3) can not rotate in the lower part (2).

For ease of use, the quick attachment with recessed grips (13,13a) on the surfaces of the lid (1) and the lower part (2) is formed.

For better playability of the pelvic bell, the quick attachment is designed as a cone tapering at the top (10).

In a modification of the illustrated embodiment, it is possible to form the through hole (12) in the clamping screw (3) four, six or octagonal. This would mean that with a corresponding counterpart (14), the quick attachment only needs to be attached or detached with one hand.
