Abstract
With a view to improving a protector device for the tension lock of a conga or the like so as to obtain cost-effective production and easy attachment and the possibility of operation of the tension nut in the attached condition, the protector device comprises a main body, which is U-shaped in its horizontal cross section and radially open on the inside toward the conga, accepting the tension lug of the conga; a cover; a bottom; a slot in the cover; a slot in the bottom; a cutout in the cover, into which the slot opens and which, in the attached position, encompasses the region of the outer thread of the tension hook; and a cutout in the bottom, into which the slot opens and which, in the attached position, encompasses the top of the tension nut.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a protector device for the tension lock on a conga or the like, i.e., for percussion instruments having a skin that can be tensioned and tuned by means of rods using a multiplicity of tension locks spaced around the instrument's periphery.
2. Background Art
Tension locks of this type are known in different percussion instruments; in congas in particular, due to the convexity of the resonant body, they often lead to damage when two congas collide during transportation or while they are being played.
It is already known to provide protector devices for the tension locks in order to prevent adjacently situated instruments from being scratched; the known protector devices have the shortcoming however, that they are not easy to attach and the instruments cannot be tuned with the protector devices attached.
SUMMARY OF THE INVENTION
Proceeding from the above, the invention has as its object to improve a protector device of the above type in such a way that it can be created cost-effectively and easily attached and that an operation of the tension nut is possible in the attached condition.
This object is solved according to the invention with a main body being U-shaped in its horizontal cross section, radially open on the inside toward the conga and accepting the tension lug of the conga; also a cover; a bottom; a slot in the cover; a slot in the bottom; a cutout in the cover into which the slot opens and which, in the attached position, encompasses the region of the exterior thread of the tension hook; and a cutout in the bottom into which the slot opens and which, when in the attached position, encompasses the top of the tension nut.
A protector device according to the invention can, accordingly, be snapped onto the tension lock in a radially inward direction, widening the slots in the process, and then reliably protects a tension lock with a protector device from scratching an adjacently situated instrument. Furthermore, injuries during carrying and playing are also prevented. Since the bottom of the protector device encloses only the upper side of the tuning rod, retightening and tuning is possible without problem even with the protector device attached.
The protector device is advantageously molded in one piece from plastic and can thus be manufactured cost-effectively. A conically outward directed base on the underside makes the protector device appear decorative and ensures additional protection, particularly for instruments where the tensioning screws are located at an angle.
The invention will be described in greater detail below based on a preferred embodiment in combination with the drawing.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1
shows a vertical section through the tension lock region of a conga;
FIG. 2
shows a side view of an inventive protector device;
FIG. 3
shows a view of the protector device from inside;
FIG. 4
shows a view of the protector device from above; and
FIG. 5
shows a section through the protector device along the line IIIāIII in FIG.

.
DESCRIPTION OF THE PREFERRED EMBODIMENT
In
FIG. 1
a section of a conga
1
is depicted in the region of the tension lock
2
. The tension lock comprises a base plate
3
with bores
4
through which fastening screws
5
are screwed into the wooden wall
6
of the conga
1
.
At the top of the conga
1
a tension loop
7
is affixed for the skin, which is not shown in the drawing, to which hooks
8
are fastened that have projections
9
that are crimped in an L-shape and have cutouts
10
into which the end
11
of a tension hook
12
engages, said end being formed like the handle of a walking cane. The end
13
opposite the end
11
of the tension hook
12
is provided with an exterior thread
14
onto which a tension nut
15
is screwed.
The tension hook
12
extends, with the region of its thread
14
, through a tension lug
16
that is connected to the base plate
3
of the tension lock
2
.
Tightening the tension nut
15
causes the tension hook
12
to be pulled downward so that tension is exerted onto the tension loop
8
and the same is tightened more firmly. By moving the tension nut
15
in the other direction, i.e., by loosening the tension nut
15
, the tension onto the tension loop
7
, and thus onto the skin, is reduced.
This tension lock
2
, especially its tension lug
16
, protrudes outward, as is apparent from
FIG. 1
, beyond the wall
6
of the conga
1
. This creates the danger of damage to other musical instruments during transportation or playing, particularly for other congas.
To provide a remedy for this situation, an inventive protector device
17
made of plastic is provided, which is shown in
FIG. 2 through 5
. It comprises a main body
18
, which is approximately U-shaped in its horizontal cross-section (see
FIG. 5
) and has a cover
19
and a bottom
20
(see
FIG. 3
in particular).
The cover
19
has a vertical slot
21
and the bottom
20
has a vertical slot
22
, with the upper slot
21
opening into an approximately circular cutout
23
and the lower slot
22
opening into an approximately circular cutout
24
that is larger relative to the cutout
23
.
The slots
21
,
22
and cutouts
23
,
24
are dimensioned such that the protector device
17
can be pushed radially inward from outside, while elastically widening the slots
21
,
22
, into the position shown in
FIG. 1
, on the tension lock
2
over the tension lug
16
, so that the cover
19
covers the tension lug
16
from the top and the bottom
20
covers the tension lug from below, with the upper cutout
23
encompassing the region of the thread
14
, and the lower cutout
24
encompassing the upper region of the tension nut
15
. The lower region of the tension nut
15
projects beyond the underside of the bottom
20
, so that a tightening of the tension lock
2
via the tension nut
15
is possible even when the protector device
17
is attached, without having to remove the protector device
17
.
The main body
18
has peripheral beads
25
and a base
26
that is conically directed outward.
