Abstract

In the case of a hairbrush, in particular with an electrically heated brush body (1) and a handle part (2), the handle part (2) has two half-shells (3) connected to the brush body (1) for sealing the handle part (2) and for easy handling of the hairbrush. 4), which are fixed to each other by detent members and the half-shells (3, 4) carry two coaxially pushed-on handle sleeves (7, 8), of which the handle sleeve (7) with the half-shells (3, 4) cannot rotate and the handle sleeve ( 8) is rotatably connected.

Description

The invention relates to a hairbrush with an electrically heated brush body and a handle part, which has two half-shells connected to the brush body.

In hairbrushes of this type, it is known to firmly connect the brush body to the handle part. this leads to the shortcoming that the handle part has to be rotated in each case to wind up hair. In addition, is at known hairbrushes to form the handle part by two half-shells connected to the brush body, which are held together by means of screws to form separating seams that are visible from the outside. The separating seams However, they are disadvantageous because they prevent splash water from penetrating the handle part and thus electrical interference allow.

It is the object of the invention to improve the sealing of the hairbrush while making it easier to use To reach the handle.

The invention according to this problem has found a solution in that the half-shells by locking members are fixed to each other and two coaxially pushed and held by shift locks Wore grip sleeves, of which one grip sleeve with the Half-shells non-rotatable and the other handle sleeve is rotatably connected. The non-rotatable one is useful Handle sleeve closer to the brush body and the handle sleeve rotatably connected to the half-shells from Brush body arranged further away.

In the hairbrush created in this way, the handle sleeves act as a cover for the half-shells and their Separating seams, whereby a seal of the handle part is achieved in the area of the separating seams. In addition, is at solid It is possible to grasp the rotatable grip sleeve, the other grip sleeve together with the half-shells and the Brush body for winding hair can be freely rotated in both directions of rotation. This results in the advantage of one-handed operation of the hairbrushes, which allows any winding without the otherwise usual handle changes can be carried out. The additional arrangement of the grip sleeves can also be simplified connection of the half-shells thereby. that in these instead of the known clamping means used Half-shell in the area of the marginal edges over the separating seams of the half-shells engaging retaining pegs and the other half-shell has recesses with boundary surfaces in the area of the marginal edges and that the half-shells are fixed to one another by gripping behind the boundary surfaces through the retaining pegs. To connect the two half-shells, only a simple process of pressing them against each other is required, wherein the preferably resiliently elastic retaining pegs automatically under the effect of Bending stresses are moved back into the rest position and grasp behind the boundary surfaces. It It goes without saying that, as a modification of the inventive concept, each of the two half-shells is at a peripheral edge Retaining pins and can have recesses with boundary surfaces on the other edge.

The shift lock for the grip sleeves can be arranged and designed in any way. Preferred the shift locks between the grip sleeves and the half-shells are provided and exist formed on the half-shells and corresponding grooves. aside from that provision is made for the grip sleeve to be firmly connected to the half-shell by engaging with it to hold molded strips in grooves of the half-shells non-rotatably on the half-shells. It goes without saying that any number of projections and corresponding grooves can be used can find. It has proven expedient to have the projections in the direction of insertion at the front with inclined surfaces to be provided, which allow the grip sleeves to be pushed on easily.

An embodiment of the invention is shown in the drawing and is explained in more detail below. It shows

In the figures, 1 denotes a heatable brush body which is firmly or detachably connected to a handle part 2. The handle part 1 (F i g. 2) has two as

as well as a handle sleeve 8, smooth on the outside, pushed on, by engaging a projection 9 in a receiving groove 10 or projection 11 in a receiving groove 12 are held immovably on the half-shells 3.4. The grip sleeve 7 also has strips 13 which by engaging in grooves 14 of the half-shells 3, 4 fix the grip sleeve 7 non-rotatably on the half-shells 3, 4. In contrast, the projections H and the receiving nut-i 12 are designed and arranged so that the Grip sleeve 8 on the half-shells is immovable, but rotatable

To erect the handle part 2, the two half-shells 3 and 4 are first placed opposite one another and by gently pressing by engaging the retaining pin 5 in the recesses 7 'and behind gripping the boundary surfaces 6 fixed to one another. Subsequently, the grip sleeve 7 until it clicks into place Formations 9 in the receiving groove 10 of the strips 13 in the grooves 14 and the grip sleeve 8 on the half-shells 3, 4 pushed on, the projections 11 locking in the receiving groove i2. By dipping one on the half-shells 3, 4 formed collar 17 in a recess 18 of the grip sleeve 8 is an additional Guidance and support of the grip sleeve 8 achieved

In the half-shells 3, 4 overlapped by the grip sleeves 7, 8, the separating seams 15 of the same are covered, whereby penetration, e.g. B. splashing water in the interior of the handle part 2 is largely omitted. at Grasping the grip sleeve 8 by the hand of the user is the grip sleeve 7 by the same hand together with the Half-shells 3, 4 and the brush body 1 for winding hair rotatable.

The power cord 16 is expediently rotatably guided in the half-shells 3, 4, as a result of which disruptive rotations do not use the power cord when winding hair. It goes without saying that the brush body 1 both at or can be connected to the half-shells after assembly of the handle part 2. The attachment also lies of replaceable brush bodies on the handle part 2 within the scope of the invention. The brush bodies can to do this, attack the half-shells 3, 4 by means of a bayonet or screw connection.
