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

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.
