Description

Brush drumstick.

Field of the Invention

The present invention makes a brush drumstick, of the type used in hairdressing, trained by a grip handle and a hollow cylindrical metal jacket with holes, crossed by bristles, in which the soul of wire to which these bristles were knotted and instead exist capsules containing said bristles embedded in said holes of said cylindrical sleeve.

Background

The drumstick brushes of use in hairdressing, mainly in the tasks in which a dryer should intervene while using said brush drumstick Shapes the hair.

This type of drumstick brushes are made up of a hollow cylindrical body whose jacket or perimeter wall. the bristles of the brush that are knotted in a wire weft in its central axis.

This is for example the case of the model of Spanish utility ES1030164U.

Despite its wide dissemination and use said drumstick brushes have drawbacks. The two more Defendants come from their own constructive nature. In fact, so that these bristles can successfully protrude from the holes of the drumstick perimeter jacket, they must have enough hardness and stiffness, which rules out using synthetic materials, for example, with greater degree of softness or flexibility.

The other drawback, less obvious than the above, is that the number of sows that can be used or knotted in the wireframe and that is able to build for running through the drumstick shirt is not very high; even these bristles must be constructed of the same material or at least Similar properties of hardness and flexibility.

To deal with these problems is so that the present invention that remedies them has been devised, substantially simplifying the construction of said brushes drumstick and allowing a comfortable mechanization of the process manufacture thereof by suppressing the wireframe characteristic of said brushes.

These and other advantages of the present invention they will be more evident throughout the description of it.

Brief Description of the Invention

The present invention develops a brush drumstick, the type of brushes that use a hollow cylinder of perforated metal jacket, whose holes are pierced by a sows of sows, in which the support of said sows of sows It is formed by a base, preferably made of material plastic or equivalent, containing said bristles, retaining them, said base being retained in the holes of the perimeter wall of the drumstick brush.

In this way the need for a center wire frame that supported the bristles of the brush, with the inconveniences that it reported.

The construction that represents the invention is In addition to simple practice regarding the manufacturing process of the drumstick brush of the invention. The bases with the bristles are They can be made of plastic materials, and then inserted into their destinations mechanically in the assembly of the brush, in a simple and economical process.

Brief explanation of the drawings

For a better understanding of the invention, accompanies it with a sheet of drawings, merely illustrative and non-limiting of the invention, in which through the different figures the same elements are always identified With the same numbers.

Figure 1 is a representation in perspective, of a part of a drumstick brush according to the technique known, with a partial cross section to show the center wire frame that supports the bristles of the brush.

Figure 2 is a perspective view of the base and bristles of the drumstick brush of the invention according to its preferred embodiment.

Figure 3 is a cross section of the shirt  cylindrical of a brush according to the embodiment of the bristle base of the previous figure, illustrating the union of said base with said Brush drumstick shirt.

Detailed Explanation of the Invention

The invention consists of a drum brush, of type of brushes formed by a hollow cylindrical sleeve (1) with holes (3) of which the bristles (2) stand out, in that said sows (2) are anchored in two bases (4), whose shape is intended to fit into said holes (3) of said cylindrical shirt (1) and be retained there.

Said attachment of said bases (4) in said holes (3) can be obtained by numerous methods. The middle used by the preferred embodiment is by the dimensions relative of the section of said bases and the diameter of said bases holes (3), and tolerances in the manufacturing process of said elements, so that when one is snapped into the another must be carried out the necessary force so that the union resulting is sufficiently safe.

In other embodiments of the present invention it may be preferred that the base has a circular groove perimeter designed to fit the hole wall, considering such variation, or any other similar one, within the scope of the present invention.

Thanks to the invention, the Kill of sows (2) of each base (4) with greater number of elements that in the conventional technique, being also possible to use more flexible materials and mix these bristles with different Sizes and qualities. For example, they can now be used much softer or more flexible materials than with the technique preceding.

In addition to suppressing the need of the plot Wireframe has simplified the manufacturing process of Said brushes

It is understood that they can be variable how many details of finish and shape do not alter the essence of the invention.

Claims (4)

1. Stick brush, of the type of brushes formed by a cylindrical shirt (1), metallic, hollow with holes (3) from which the combing bristles (2) stand out, characterized in that said bristles (2) are anchored in each base (4), the shape of said bases being intended to fit into said holes (3) of said cylindrical sleeve (1) and be retained there. 2. Stick brush according to the preceding claim, characterized in that said bases (4) are approximately cylindrical in shape. 3.
