Benefits of technology

"The present invention provides an angular brush that is simple in construction and without any drawbacks of traditional brushes. The handle of the brush has a tenon with a profile that includes a circular recess and a lateral chamfer. The brush also has bristles that are fixed to the handle using glue. The glue grips the bristles and the recesses. The invention simplifies the construction process and eliminates the use of nails, reducing the likelihood of breakages or cracks in the wood."

Problems solved by technology

With prolonged use of the brush, these nails tend to cause cracks to open in the wood of the handle, they can rust and hence ruin the brush, to the extent of making it unserviceable.
Moreover, when they are inserted into the wood they tend to raise the collar, hence forming a slight projection on the collar which can be annoying if not dangerous to the user.

Embodiment Construction

[0016] With reference to the accompanying figures, the brush consists of a handle 10, bristles 12 and a collar 16.

[0017] At one end, namely in its wider end, the handle 10 has a tenon 11 having on its outer edge a profile 13 which is inclined by an angle α of about 70° to a central axis 15 of the brush, in the direction of the brush length.

[0018] This is therefore a so-called angular brush, i.e. presenting the end of the bristles 12 inclined by the predetermined angle α. The collar 16 is also of inclined type.

[0019] The profile 13 presents a chamfer 20, preferably on both sides (the longer sides) to enable it to more easily penetrate into the glue subsequently used for gluing.

[0020] At the point at which it engages the handle 10, the tenon 11 has a perimeter slightly less than that of the handle along a section taken at that point. In this manner an edge 17 is obtained at which to position the collar 16.

[0021] The bristles 12 are grouped together to form a pack suitable for the...

Abstract

Handle for angular brush characterized in that said handle comprises, at one end of said handle, a tenon having a profile inclined to the central axis of said handle, said profile comprising at least one circular recess, said profile further comprising at least one lateral chamfer along a major side thereof.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a handle for an angular brush having an holding tenon for the glue, to the relative brush and to the method for its construction. [0002] Brushes consist of an elongated handle to which bristles are fixed. The bristles are firstly glued together at one end to form a pack. They are then fixed to the handle by means of a collar. The collar is fixed to the brush by two nails or clouts. [0003] With prolonged use of the brush, these nails tend to cause cracks to open in the wood of the handle, they can rust and hence ruin the brush, to the extent of making it unserviceable. [0004] Moreover, when they are inserted into the wood they tend to raise the collar, hence forming a slight projection on the collar which can be annoying if not dangerous to the user. SUMMARY OF THE INVENTION [0005] The object of the present invention is to provide a brush which is without the drawbacks of the known art, and is of simple construction. [000...
