Abstract

The invention concerns a device for shaping and smoothing join materials, such as silicone, with a container (4) for a surfactant liquid, such as water mixed with washing-up liquid. The container comprises an applicator head (5) with an outlet opening (8) which is connected to the container interior and in which a sphere (10) is disposed such that it projects partially out of the outlet opening. As the projecting part of the sphere rolls on a join material, the sphere conveys liquid out of the container interior, through the outlet opening and onto the join material, shaping the latter at the same time.

Description

Floor roller

The invention relates to a device for molding and smoothing joint materials such as silicone.

Jointing materials are used in a wide variety of cases. So silicone is used in the interior of painters, tile builders, sanitary technicians, glaziers and window builders. Furthermore, joint materials are used for sealing or fastening furniture or decorative items such as aquariums or in metal processing.

Silicone is usually applied using a spray gun. Subsequently, it is usually pressed as evenly as possible into the joints with a finger moistened with Pril water (water with a portion of Pril dishwashing liquid from Henkel or the like. Detergent) and smoothed. The Prilwasser is carried in a cup. This procedure is cumbersome, complex and unsatisfactory, particularly with regard to the shape of the joint material at the points where the finger is attached or removed for moistening. When painting in an apartment, many meters of silicone are usually processed in this way with uneven results.

Proceeding from this, the object of the invention is to create a device which facilitates the shaping and smoothing of joint materials and leads to more uniform results.

The object is achieved by a device having the features of claim 1. Advantageous embodiments of the device are specified in the subordinate claims.

The device according to the invention has a container for a surface-active liquid such as water and an application head with a ball arranged therein. The ball can be wetted on its section facing the interior of the container with liquid, which it transports through the outlet opening onto the joint material when it rolls off. At the same time, the joint material is formed by the surface of the rolling ball. Unlike a fundamentally similar deodorant roller, the device is used in an inventive manner in this completely different area not only for the application of liquid but also as a shaping and smoothing tool.

The ball can sit in the outlet opening with some play, so that the liquid is transported outwards through a small gap when it rolls off. An unintentional leakage of liquid can then be prevented by a cap which presses the ball into a sealing seat. The ball can also be sealed in the order opening sit and transport the liquid to the outside as it rolls off by means of fine depressions in its surface. Preferably, however, the ball is pressed against the outlet opening by a spring device and, when pressed against the joint material, is pressed somewhat so that it releases the outlet opening somewhat and, when it rolls off, liquid is transported outward through the gap formed onto the joint material. This ensures that liquid can only reach the outside when the ball is pressed. Due to the good fluidity of the surface-active liquid, the ball can usually be pushed into the container by a maximum of one millimeter and less.

The spring device can be an elastic element made of rubber, plastic or metal. For example, it is a helical spring which is supported at one end in the container and at the other end presses against the ball. The spring device can also be elastic supports of an axis on which the ball is rotatably mounted. Then the ends of the axis can engage in guide grooves of the application head and the supports can be arranged in the guide grooves.

In principle, the ball can be rotatably mounted in the application head in any direction. A bearing on an axis comes into consideration especially when the "ball" deviates from the ideal ball shape. The ball can be flattened laterally in order to be able to be guided into narrow corner areas. It can have the shape of an impeller with convexly curved treads. For insertion into narrow corner areas, the application head can also have a taper on the outside. In order to support rolling, the ball is preferably shaped so that it rolls over the fixed joint edge areas. The ball preferably has two oppositely directed frustoconical (flat in cross-section) running surfaces on the sides, so that it has better adhesion to the joint edge areas. For this purpose, it can also have treads with improved frictional grip, for example in the form of a rubber coating.

The container can be pin-shaped for easy handling. The application head can be detachably seated on a filling opening of the container for surface-active liquids. The application head is preferably a screw head. Furthermore, the application head can have circumferential beads (or other surface structures such as corrugations) which can serve for grip. For sealing purposes, a sealing ring can be arranged between the removable application head and the container.

Furthermore, the container can have a removable cap for sealing and protective purposes, which covers the projecting part of the ball. The cap can have a snap connection to the container.

Finally, the container can have several identical or different application heads (for example with regard to the dimensions, shapes and / or materials of the balls) and / or a set of several identical or different removable application heads for different work steps or for processing joints of different sizes (For example with regard to dimensions, shapes and / or materials of the balls). The invention is described below with reference to the attached drawings of two exemplary embodiments. games explained. The drawings show:

6 and 7 a first application head (FIG. 6) and a second application head (FIG. 7) of the device, each in section in the working position on a joint;

FIG. 8 shows a ball of the application head according to FIG. 6 in a top view; FIG.

9 and 10 a first cap (FIG. 9) and a second cap (FIG. 10) of the device, each in a side view.

First, the device of FIGS. 1 to 4 is described. 1, its container 1 is pin-shaped and provided with an external thread 2 at the top. On the upper edge of the thread 2, a sealing ring 3 is placed, which surrounds a filling opening 4 of the container 1 for primary water.

The application head 5 according to FIG. 2 has a sleeve-shaped screw body 6 with one extending to the lower end Internal thread 7. At the top, the screw body 6 has an outlet opening 8, with guide grooves 9 being formed in its wall on two opposite sides. In the outlet opening 8 sits a ball 10 which is guided at the ends of an axis 11 in the guide grooves 9. The axis 11 is held at the top by a projecting edge 12 of the screw body 6, which forms a taper on the outside towards the ball 10. At the bottom, the axis 11 is supported on small coil springs 13 which are seated in the guide grooves 9 and are supported in the screw body 6 at their other end. 3, the ball 10 has a smooth central section 14 and two rubber-coated and profiled running surfaces 15.

Furthermore, the screw body 6 has an outer circumferential locking projection 16 at the bottom.

4 at the lower end of its cylindrical body, the cap 17 has an encircling locking projection 18 on the inside, which snaps behind the locking projection 16 when the cap 17 is snapped onto the application head 5 covering the ball 10.

If the container 1 and the application head 5 are screwed apart according to FIGS. 1 and 2, Prilwasser can be filled into the container 1 through the filling opening 4. The application head 5 is then screwed with its internal thread 7 onto the external thread 2 of the container 1. After the cap 17 has been removed from the application head 5, the device with its ball 10 can be attached to a joint 19 in order to shape and smooth silicone material 20 introduced therein with the supply of prilled water. After use, the device is placed on the cap 17 Gun 5 protected.

In the device according to FIGS. 5 to 10, the parts which correspond to the device described above are provided with identical reference numbers. This device has a further application head 5 ', the features relating to this, which correspond to those of the device according to FIGS. 1 to 4, being identified with an identical reference number with a coat of paint. In this respect, the above description applies to both devices.

Both application heads 5, 5 'have, on the outer circumference, annular beads (semicylindrical in cross-section) 21, 21', which are staggered axially one behind the other. Furthermore, the two associated caps 17, 17 "each have a clamping bracket (" clipper ") 22, 22 ', such as a ballpoint pen.

The application heads 5, 5 'differ by balls 10, 10' of different diameters. This makes it possible to roll out different joints 20, 20 'with the same joint roller. Both balls 10, 10 'have a smooth middle section and two rubberized and profiled running surfaces on the surface.

So that not too much silicone is brought into the joint and this is pressed forward at the edges of the ball 10 of a joint roller, it must be tested how far the tip of the silicone cartridge may at most be cut off. When the optimum section length has been found, it is transferred as a type of gauge to the application head or to another suitable location (printed, pressed, etc.). This makes it even easier for anyone to handle the tool.
