Definitions

the invention relates to a paint roller with a hollow roller mounted on a multi-angled handle, covered with plush or the like, with a cylindrical roller core, which is held concentrically in the roller by radial webs and in which a slotted bearing bush, which holds the bearing leg of the handle part, holds axially is unmovably pivoted.
Paint rollers of this type which have a relatively simple structure and nevertheless function reliably under room operating conditions, have already been proposed in a wide variety of embodiments.
the roller, the roller core and the axial webs form a one-piece component, which is manufactured by injection molding.
you need their own molds for production which makes the very large amount of effort required with the large number of paint roller types.
the invention has for its object to design a paint roller of the type mentioned so that different sizes can be manufactured more easily.
a paint roller of the type mentioned is characterized according to the invention by a molded part comprising the roller core, the radial webs and a sleeve which connects the webs in the region of their outer edges at least on part of their axial extension and which is pressed into the roller designed as a simple tube piece is.
the separate molded part provided according to the invention which comprises the roller core and the radial webs, it is no longer necessary, for example, for only one change in the length of the paint roller, to provide separate shapes for this, since the rollers themselves can be simple cut-to-length parts of long tubes which can be provided in any length.
the same component comprising the roller core can be pressed in, so that ultimately only one injection molded part is necessary for the bearing component for all conceivably different lengths of a roller.
the need for providing such different bearing components with the roller core for different roller diameters which of course still exists, is of course much easier to solve.
the radial webs and a short sleeve can, of course, be produced much more easily than the one-piece part previously required, which also includes the roll , large component. The following are considerably smaller and therefore also much cheaper and easier.
the sleeve is to be provided with a plurality of spaced, circumferential, angular ribs which, due to the deformation of the inner surface of the roller, are pressed in so far that an axial displacement is only necessary with considerable effort, which never occurs when using a paint roller.
this high force for breaking in the molded part means no production obstacle either, since this can be easily achieved in automated production with the aid of corresponding hydraulic press rams.
the paint roller shown consists of a handle part 1 with a multi-angled, dimensionally stable wire bracket 2, one end of which is provided with a handle 3, while the bearing leg 4, which is inclined essentially by 90 ° with respect to the handle, serves to support the actual paint roller 5, which is made of a roller 6 and a cover 7, which can either consist of plush or could also be formed, for example, by flocking the roller 6.
the actual bearing of the bearing arm 4 is carried out by an essentially central bearing bush pivot bearing.
a slotted bearing bush 10 which is clamped onto the bearing leg 4, is supported in a roller core 11, which is supported on the inner wall 13 of the roller 6 via a plurality of radial webs 12.
the roller core 11 is provided with an inner annular rib 14 which engages in a corresponding annular groove of the bearing bush 10 and ensures the axial immovability of the bearing.
the roller core 11 and the radial webs 12 form a separate component, the webs being connected over part of their longitudinal extent by a sleeve 15, the outer surface of which lies in the peripheral surface of the outer web edges 16, the sleeve 15 being intended to be shorter in its longitudinal direction than the longitudinal extension of the webs and the roll core.
the sleeve 15 is provided on the outside with several contested, cross-sectionally triangular ribs 17 which, when this separate bearing component 18 is pressed into the roller 6, which can represent a very simple piece of pipe, ensures displacement-secured storage at the desired central location, which only can be lifted again by extremely high pressing forces, as they never occur in practice when using such paint rollers.
the radial webs 12 are provided with bevels 19 on both ends.
the invention is not restricted to the exemplary embodiment shown.
another attachment of the plush cover could also be provided, for example, by placing it around the end edges of the roller, so that it is between the outer edges of the clamping webs 20 and the inner surface 13 the roller is jammed.
