Abstract

The invention relates to a device for the flat application and incorporation of powdery products with an applicator body (1) which can be rotated and with a guide aid (4) attached to its bearing (2). To ensure a good supply of product and a secure locking and switching off of the product flow when massaging in, the applicator body is designed as a foam ball (1), while its storage takes the form of a ball head (2) partially enclosing the ball (1), in which the ball (1) can be held or locked with the help of a clamping ring (3). A product container (4) molded onto the ball head (2) is provided as a guide (Fig. 4).

Description

The invention relates to a device for the flat application and incorporation of powdery or free-flowing products, in particular on vertical upholstery surfaces, with an applicator body which can be rotated and with a guide aid attached to its mounting.

Powder applicators of this type are used to apply cleaning powder to carpets or the like. The applicator body is designed as a roller or roller. It has already been proposed in this connection to design the roller as a cylindrical hollow body for receiving the powder to be applied and to equip the jacket of the roller with powder passage holes. Because of the roller shape, application to curved surfaces, e.g. on upholstered furniture, difficulties. It is also problematic to work in after applying the powdered or free-flowing product to the respective object. Although it is possible to lock the respective roller for this purpose, so that the powder feed is essentially switched off, but since the powder is in the roller, a significant leakage of powder from the cavity inside the roller cannot be ruled out during the massaging process .

The invention has for its object to provide a powder applicator for applying powdered and free-flowing product to any orientation and shaped upholstered surfaces is suitable and, after application, allows incorporation into the respective base surface, in which a noteworthy escape of powdered product is excluded. The solution according to the invention is characterized for the device for the flat application and incorporation of powdery or free-flowing products of the type mentioned initially with an applicator body which can be rotated and with a guide aid attached to its mounting, characterized in that the applicator body as a foam ball and its storage as the ball partially but to hold on sufficiently wide enclosing and optionally rolling or locked ball head are formed and that a product container attached to the ball head with connection to the foam ball is provided as a guide.

The ball head is preferably formed from a hemisphere receiving the foam ball with a clamping ring placed thereon for holding the foam ball. A spherical section of an inserted foam ball comes to light through the ring opening of the clamping ring. The clamping ring should have two positions: in one position, the foam ball is only held loosely so that it rolls past the surface to be treated in the ball head and conveys powder brought to the bottom of the ball head outwards and thus onto the object to be treated. In another position, the clamping ring is locked in such a way, preferably with the aid of special braking means, such as in particular axially standing ribs or a toothed strip on the bottom of the spherical shell, that rotation is no longer possible. For locking, the clamping ring can be pressed against the foam ball with a predetermined force. It is also advantageous if the normal of the spanned by the clamping ring Spherical section surface is inclined by approximately 30 to 40 ° with respect to the longitudinal axis of an attached product container which also serves as a guide.

Accordingly, the invention provides a ball head inclined to the powder container axis with a foam ball accommodated therein and partially enclosed. The geometric arrangement according to the invention in connection with the shape of the product container designed as a guide aid ensures when the foam ball rolls over any inclined, in particular horizontal or vertical, surfaces, e.g. Pad that the product automatically trickles and is applied over the foam ball acting as an applicator.

At the same time it is achieved by the invention that subsequent to the application, it is possible to massage the product in using the same foam ball if this, e.g. is locked in the ball head with the help of a circumferential clamping ring. A locking ring with ribs arranged axially on the inside can be used as a lock, which is guided over the ball head with the aid of a thread and, depending on the position, clamps or holds the foam ball in a rollable manner. The device can also be constructed in such a way that a toothed strip is provided in the ball head strapping pointing towards the interior of the container, which holds the foam ball after pressing on the surface to be treated and thus prevents further rolling and conveying of product to the outside of the ball.

Details of the invention are explained on the basis of the schematic representation of exemplary embodiments. Show it:

• Figures 1 and 2 side views of a powder applicator with associated product container.
• FIGS. 3 and 4 enlarged illustrations in two positions each in the side view and in section of the applicator head according to FIG. 1; and
• 5 and 6 the clamping ring in side view, partly in section, or in the view from below to hold the foam ball in the ball head.

1 and 2, a device according to the invention is shown schematically in two side views. The applicator body is designed as a foam ball 1. The storage of the applicator body consists of a ball head, designated overall by 2, which partially but sufficiently encloses the foam ball 1 to hold it in place. According to the enlarged side view or according to the section according to FIGS. 3 and 4, the foam body can be arranged in a spherical head which is in principle designed as a hemisphere, on which a clamping ring 3 can be placed in at least two positions to hold the foam ball 1 in place. The coupling elements between the ball head 2 and the clamping ring 3 are, for example, threads, Bejonett guides and tongue and groove connections with a corresponding pitch.

The respective product container 4 directly adjoins the underside or back of the ball head 2. When the applicator to apply cleaning powder Upholstered furniture is provided, the container 4 can have, for example, a volume of 500 ml. In order to ensure that the applicator according to the invention is suitable for application to both vertical and horizontal upholstery surfaces, the normal 5 of the surface of the circular clamping ring opening 6 is arranged inclined by approximately 30 to 40 ° with respect to the longitudinal axis 7 of the container 4.

The connection between the tension ring 3 and ball head 2 consists in FIG. 4 of a thread 8 and in FIG. 5 of a bolt 9. It is essential that the tension ring 3 is locked in two height positions A and B (FIGS. 3 and 4) , In position A a free rotatability of the foam ball 1 should be ensured, while the foam ball 1 should be held in position B of the clamping ring so that it does not rotate relative to the ball head 2 when used to massage in previously applied powder. The clamping ring 3 itself should, if possible, be designed in such a way that powder discharge is normally not possible on the circumference of the ball head between the clamping ring and the adjacent hemisphere. For this purpose, it may be expedient to allow the clamping ring to reach over the free edge 10 of the ball head 2 in such a way that a sealing lip 11 engages over the free end 10 of the ball head 2 in each clamping ring position on the inside of the ball head.

To lock the foam ball 1 in position B according to FIG. 3, it may be desirable to provide special braking means on the inside of the clamping ring 3. For example, the clamping ring inner surface pointing towards the inside of the container can have teeth 12. The same we kung also has a toothed bar 13 formed in the base region of the ball head 2. When the clamping ring 3 is pressed in position B, the teeth 12 emboss into the foam ball 1 and prevent the ball from rolling when massaging a substrate.
