Patent Application
20220105537
The present invention relates to a rosin spreader especially adapted for the bow hair of stringed instruments such as violin, viola and cello. Excessive rosin powder on the bow hair can reduce the performance of the bow. Toothbrushes have been used to wipe off rosin dust on the bow hair. However, such toothbrushes can wipe off only minor clumps of rosin powder and are not effective to evenly distribute rosin particles on the bow hair. Such toothbrushes can even damage the bow hair. In fact, no particular rosin spreaders designed exclusively for the bow hair of stringed instruments have been available.
Therefore, it would be desirable to provide a rosin spreader that not only easily wipes off excessive rosin, but also evenly distributes rosin particles on the bow hair.
The present invention is directed to a rosin spreader that overcomes the above-mentioned disadvantages of the prior art.
In one aspect, the present invention provides a rosin spreader having a body, a plurality of substantially parallel, spaced apart, elongated first teeth, a plurality of substantially parallel, spaced apart, elongated second teeth, a plurality of bristles, an elongated first sidewall, and an elongated second sidewall. The body has a top surface, a bottom surface, and a peripheral edge. The first teeth extend outwardly from the top surface of the body. The second teeth extend outwardly from the top surface of the body. The first teeth and the second teeth are secured to the top surface of the body. The first teeth and the second teeth are in spaced parallel relationship. The bristles extend outwardly from the top surface of the body. The bristles are positioned between the first teeth and the second teeth. The bristles are secured to the top surface of the body. The first sidewall extends upwardly from the top surface of the body. The second sidewall extends upwardly from the top surface of the body. The first sidewall and the second sidewall are secured to the top surface of the body. The first sidewall and the second sidewall are in spaced parallel relationship. The first teeth, the second teeth, and the bristles are positioned between the first sidewall and the second sidewall.
In another aspect, the present invention provides a rosin spreader having a body, a plurality of substantially parallel, spaced apart, elongated first teeth, a plurality of bristles, and an elongated first sidewall. The body has a top surface, a bottom surface, and a peripheral edge. The first teeth extend outwardly from the top surface of the body. The bristles extend outwardly from the top surface of the body. The first sidewall extends upwardly from the top surface of the body. The first teeth, the bristles, and the first sidewall are secured to the top surface of the body.
In a further aspect, the present invention provides a rosin spreader having a body, a plurality of substantially parallel, spaced apart, elongated first teeth, a plurality of substantially parallel, spaced apart, elongated second teeth, a plurality of bristles, an elongated first sidewall, and an elongated second sidewall. The body has a top surface, a bottom surface, a front and a peripheral edge. The first teeth extend outwardly from the top surface of the body. The first teeth extend in directions substantially 90° from the top surface of the body. The second teeth extend outwardly from the top surface of the body. The second teeth have an identical material, thickness and/or extent in the longitudinal direction of the first teeth. The first teeth and the second teeth are secured to the top surface of the body. The first teeth and the second teeth are in spaced parallel relationship. The bristles extend outwardly from the top surface of the body. The bristles are positioned between the first teeth and the second teeth. The bristles are secured to the top surface of the body. The first sidewall extends upwardly from the top surface of the body. The first sidewall is adjacent to the front of the body. The second sidewall extends upwardly from the top surface of the body. The first sidewall and the second sidewall are secured to the top surface of the body. The first sidewall and the second sidewall are in spaced parallel relationship. The first teeth, the second teeth, and the bristles are positioned between the first sidewall and the second sidewall.
The present invention will be described by way of exemplary embodiments, but not limitations, illustrated in the accompanying drawing in which like references denote similar elements, and in which:
Various aspects of the illustrative embodiments will be described using terms commonly employed by those skilled in the art to convey the substance of their work to others skilled in the art. However, it will be apparent to those skilled in the art that the present invention may be practiced with only some of the described aspects. For purposes of explanation, specific numbers, materials and configurations are set forth in order to provide a thorough understanding of the illustrative embodiments. However, it will be apparent to one skilled in the art that the present invention may be practiced without the specific details. In other instances, well-known features are omitted or simplified in order not to obscure the illustrative embodiments. Various operations will be described as multiple discrete operations, in turn, in a manner that is most helpful in understanding the present invention. However, the order of description should not be construed as to imply that these operations are necessarily order dependent. In particular, these operations need not be performed in the order of presentation. The phrase “in one embodiment” is used repeatedly. The phrase generally does not refer to the same embodiment, however, it may. The terms “comprising”, “having” and “including” are synonymous, unless the context dictates otherwise.
This present invention provides a rosin spreader that could dramatically improve the performance of the bow, not only by wiping off such excessive rosin on the bow hair, but also by evenly distributing rosin particles on the hair.

In an exemplary embodiment, and as illustrated in
Referring to
Preferably, the first teeth 120 and the second teeth 130 may comprise one or more materials selected from the group consisting of: wood, metal, and plastic. The first teeth 120 and the second teeth 130 may be further comprised of a metal, plastic, or other suitable flexible, semi-rigid material. The first teeth 120 and the second teeth 130 can be attached to the top surface 111 of the body 110 in a variety of ways, including heat welding and adhesives. However, the first teeth 120 and the second teeth 130 are preferably affixed to the top surface 111 via a heat welding that securely holds the first teeth 120 and the second teeth 130 in position. Thus, the first teeth 120 and the second teeth 130 remain securely attached to the top surface 111 of the body 110 when the first teeth 120 and the second teeth 130 are in use.
Referring to
In an exemplary embodiment, and as illustrated in
Preferably, the first sidewall 150 and the second sidewall 160 may comprise one or more materials selected from the group consisting of: wood, metal, plastic, and rubber. The first sidewall 150 and the second sidewall 160 may be formed from a semi-rigid or flexible material. The first sidewall 150 and the second sidewall 160 may be secured by heat welding or adhesives to the top surface 111 of the body 110.
Referring to
Thus, the present invention disclosed herein provides an improved rosin spreader that not only wipes off excessive rosin, but also evenly distributes rosin particles on the bow hair by implementing such teeth and bristles. While the present invention has been related in terms of the foregoing embodiments, those skilled in the art will recognize that the invention is not limited to the embodiments described. The present invention can be practiced with modification and alteration within the spirit and scope of the appended claims. Thus, the description is to be regarded as illustrative instead of restrictive on the present invention.
