Description

field of use

The invention relates to a brush set which comprises at least one brush for brushing and massaging the skin. It can be used to brush off different objects, animals as well as human body parts.

Technical background

Brushing human or animal skin is desirable for several reasons, be it as a pure massage effect or to remove the top, dead skin layers.

For this, it is known, on the one hand, to use brushes with different hardness of the bristles to adapt to the more or less sensitive body region to be brushed and depending on the skin type.

Furthermore, it is known to use brushes with bristles, the cross section of which is relatively large compared to their length and which are slightly flexible about a transverse axis of the respective bristle.

In contrast, thin, pointed and less flexible bristles are often perceived as unpleasant.

Such brushes - especially for wellness and massage purposes - are preferably carried out directly by hand, since the most precise dosage of the contact pressure is possible.

However, if no second person is available as a helper, your own back regions of the body can often only be reached with an aid, by attaching a long handle to the brush so that you can brush your back yourself.

In the known brushes, these are rigidly attached to the handle, which means that a flat support of the brush surface on the body surface is often not possible.

Is already known from DE 298 03 030 U1 the use of different brush attachments and a releasable fastening device between a handle and the respective brush attachment, whereby the respective brush attachment can be held directly in the hand or by means of the handle.

A brush attachment can also have a special connection area, by means of which a handle or a handle can be attached to it, as shown in DE 20 2011 001 755 U1 is shown.

A detachable connection in the form of a quick release between a brush attachment and a handle is over DE 196 15 856 A1 known.

Presentation of the invention

Technical task

It is therefore the object of the invention to provide a modular system for a brush arrangement with which a brush arrangement for the respective application can be easily created from a few different individual parts.

Solution of the task

This object is solved by the features of claim 1. Advantageous embodiments result from the subclaims.

Because both the handle and the handle have a fastening device for the brush - and if necessary the brush has a corresponding counter element - these at least three components of the modular system can be combined as desired to form a brush arrangement that fulfills the respective application.

The kit can of course include different brushes, for example with a different degree of hardness of the bristles, different shape or size of the brush, etc., and the kit can also include different handles instead of just one handle, as well as different handles, for example handles of different lengths or flexible.

One possibility for a handle is a length-adjustable hand strap, which has a fastening device for fastening to the brush.

If the fastening device on the brush consists of two spaced openings through the main body of the brush, which are sufficiently large to pass the hand strap, the hand strap can be passed through both openings and its ends can be connected to one another, for example by means of one, behind the rear of the brush Velcro fastener, which also enables a length adjustment of the wrist strap to adapt to different users.

The handle can also consist of two separate holding straps, one of which protrudes in different directions after being fastened to the brush, so that one can use two such straps can hold the brush with his hands behind his back and run along the back of the user.

For fastening to the brush, the two holding straps are passed again, for example, through the openings in the basic brush body, and each form a loop, which can be formed by an eyelet element or also by means of a Velcro fastener part.

The fastening device of the handle on the brush preferably comprises a joint which can be pivoted about at least one pivot axis which runs parallel to the main plane of the mostly plate-shaped body of the brush.

This joint can only be pivotable about one pivot axis or about several pivot axes.

Thus, the joint can be designed as a ball joint, in which one joint part consists of an almost complete, protruding ball, while the other joint part consists, for example, of a ball socket, which can also be formed by two bearing walls running parallel and at a corresponding distance from one another, in their inner surfaces facing each other have recesses of such a type and shape that the joint ball can latch therein.

In order to allow at least a limited mobility in addition to pivoting about an articulation axis about other axes, two guide lugs can be provided close to the articulated ball and at a distance from this or opposite the articulated ball, which protrude between the two bearing walls in the assembled state of the articulation.

If these guide lugs are correspondingly narrower than the distance between the bearing walls, the guide lugs can move back and forth somewhat between the bearing walls and thus offer limited pivotability about a pivot axis that is perpendicular to the main plane of the brush body.

The kit preferably includes an adapter, in particular to attach the handle to the brush.

The adapter has on its rear side the fastening device for fastening the handle and on its front side a fastening device for fastening to the brush body.

The fastening device on the rear, for fastening the handle, can be, for example, the joint described, for example the joint ball.

The fastening device on the front side for fastening to the brush base body can be latching projections which are suitable for pushing through and latching in the openings in the brush base body.

The bristles of the brush are preferably made in one piece with the brush base, for example by means of spraying.

The bristles are preferably made of a rubber-like material and can have a defined hardness due to the specific choice of the material.

The bristles have the smallest diameter of their cross section compared to their length, so that the minimum diameter is at least 1/30, better 1/20 of the length of the bristle. This results in a relatively large contact area of the free end of the bristle on the skin, so that unpleasant scratching is avoided.

The bristles have a preferably polygonal, for example triangular, cross section and can be hollow or solid in their interior, but preferably have a closed free end.

The bristle trim of the brush is convex when viewed from the side, that is to say the free ends of the bristles lie on a contour that is convex when viewed from the side. The attachment point for the handle, usually the joint, is located in the central area of the brush body as viewed from above.

When viewed from the side, the handle is concavely curved and has a fastening device for the brush at least at one end of the handle, preferably also in the middle of its longitudinal extent, on the concavely curved side.

The stem is either rigid or resilient and pliable about a transverse axis that is parallel to the center of curvature of its concave shape.

1a shows the stem 3rd in the side view.

It can be seen that the stem 3rd on the front in one end area as well as in the middle area one fastening device each 22 for attaching the brush 1 has, as in below 1b equipped with an adapter 8th is shown.

In the side view is the stem 3rd slightly curved so that the front is slightly concave, and the stability of the stem 3rd is chosen so that the stem 3rd somewhat compliant about a transverse axis 11 to the stem 3rd which is parallel to the front on which the fastening devices are located 22 are located.

At the other end where there is no fastening device 22 is present is the stem 3rd , which has a flat elongated cross section, from a through opening 23 permeated the stem 3rd to be able to hang on a hook or to be able to pass a hanger through it.

• Die Befestigungsvorrichtung 22 umfasst auf der Seite des Stieles 3 eine etwa zylindrische Vertiefung 14, in die eine Gelenkkugel 15 einrasten kann, wie sie auf der Rückseite des Adapters 8 in 1b dargestellt ist.

The fastening device 22 consists of a joint 7 :

• The fastening device 22 embraces on the side of the stem 3rd an approximately cylindrical recess 14 in which a joint ball 15 can snap into place as they are on the back of the adapter 8th in 1b is shown.

From the cylindrical recess 14 extend from both sides in the longitudinal direction of the stem 3rd two storage walls 13 at a distance from each other, between each of which a guide lug 16 fits on both sides of the joint ball 15 also from the back of the adapter 8th protrudes from. The height of the leading lugs 16 is less than the height of the storage walls 13 , so that when the fastening device is closed 22 , so if the joint ball 15 in the recess 14 is engaged, the adapter 8th with the brush 1 still about a pivot axis 9 of the stem 3rd that are transverse to the longitudinal direction of the stem 3rd and parallel to the front of the stem 3rd runs, can be pivoted.

The brush 1 can - as in the top view of the back, i.e. the base body 1a the brush 1 in 2c recognizable - be round or have any other shape.

The basic body 1a however, has a slot-shaped opening at two opposite ends 5 which in the sectional views of the brush in 1b and 1c is visible, and can serve different purposes.

If the brush 1 , as in 1b shown on a stick 3rd To do this, the adapter is used first 8th on the back of the body 1a the brush 1 attached by latching by from the front of the striped adapter 8th - the one in view of the back in 2 B is shown - locking projections 12 stick out in the breakthroughs 5 of the basic body 1a fit and snap into this.

Then the unit can be adapter 8th and brush 1 with those on the back of the adapter 8th existing parts of the fastening device 22 on the corresponding fastening device 22 of the stem 3rd be attached.

The brush 1 can also be done directly with the hand or hands.

Then not the adapter 8th on the brush 1 attached but as in 1c shown z. B. a wrist strap 4th as a handle 2nd on the brush 1 attached.

For this purpose the wrist strap has 4th such a thickness and width that it runs along the back of the body 1a guided and through the breakthroughs 5 to the front and from there again around the outer edge back to the back where the loose ends of the wrist strap can be passed 4th via a closure, e.g. B. a Velcro area 6 , can be fixed against each other.

Then the user can go through the closed wrist strap 4th grab for better guiding of the brush 1 .

But if you want the brush 1 by hand e.g. B. behind the back, you can on either side of the brush 1 , so in each of the breakthroughs 5 , a tether 17th fasten, which in turn through one of the openings 5 performed and by z. B. a Velcro area 6 a short attachment loop is closed while you pull the loose long end of each of the tether straps 17th can hold in your hand behind your back.

The bristles 20th the brush are made of a rubber-like material, and have a polygon, for example triangular or V-shaped or round, hollow or solid, cross section, as in 3rd shown in the supervision of a part of the bristle trimmings in several variants (V-shaped, round, rectangular). It is clear here that the cross sections of the bristles are arranged in rows and offset from one another, but are aligned identically or radially outward from the center of the brush.

In the side view of the brush, the free ends of the bristles can form a plane, as in 1b shown, or a crowned contour 19th , as in 1c shown.

The bristles 20th are in one piece together with a bristle base 21st manufactured, preferably by injection molding. This bristle base 21st can either be retrofitted to the brush body 1a through z. B. be glued or be integrally formed with this, for example, manufactured in a single or multi-stage spraying process.
