Definitions
- the invention relates to a paint roller according to the preamble of claim 1.
- Paint rollers are used to apply paint to walls, ceilings or the like.
- simply constructed paint rollers with a larger roller diameter consist of an outer tubular body on which a roller cover made of plush, fur, foam or the like is applied.
- the ends of the roller body are closed by end caps, which simultaneously form the bearing for a multi-angled paint roller bracket.
- the paint roller bracket must be axially secured, which happens in the known device in that the end caps are connected via an inner tube into which the paint roller bracket can be inserted, the paint roller bracket forms a positive constriction with the inner tube.
- the end caps and the inner tube is pressed firmly into the tube body. Disassembly of the individual parts is not intended. Cleaning such paint rollers after use is always very tedious, so that the entire paint roller is often thrown away after use.
- roller cover is firmly attached to an inner tube which is closed on one side and which receives the paint roller bracket with a snap-in connection.
- a paint roller has become known from DE 30 14 285, in which the roller cover is folded over the ends of the outer tubular body and the ends are pressed into the interior of the tubular body by means of the end caps.
- the end caps form the bearing for the paint roller bracket via tubular projections, an inner support tube being provided for receiving an adhesive sleeve or clamping sleeve securing the axial position of the bracket.
- the adhesive sleeve also takes on a storage function for the paint roller bracket.
- a corresponding construction is shown in DE 35 27 646.
- paint rollers have the disadvantage that they are difficult to clean, since paint can penetrate partly into the interior of the paint roller or at least into parts of the end caps, which makes cleaning very difficult.
- paint rollers are constructed in such a way that they can only be removed by destroying the paint roller. As previously stated, such paint rollers are therefore very often thrown away after a single use, which is not very environmentally friendly.
- the "environmental roller” proposes a construction which consists of an outer, separate tubular body of a predetermined length, on which the desired roll cover is firmly attached. This tubular body with roller cover serves as a disposable part after single or multiple use.
- the base body to be inserted into the tubular body and always reusable, including the paint roller bracket, consists of two cylindrical end caps which are integrally connected to one another via an inner tube for receiving the paint roller bracket.
- the base body has axially parallel stiffening ribs arranged on the lateral surface. This base body can be easily pulled out of the tubular body. However, it is a self-contained, one-piece plastic part, which is firmly and permanently connected to the paint roller bracket. Due to the disassembly, the inner body can be easily cleaned and is therefore available for constant reuse.
- the environmental scooter described has the disadvantage that the basic body is fixed in its outer dimensions and in particular in its length, since it is manufactured as a one-piece part.
- the length of the inner base body must therefore be adapted to this. Since very different lengths of the paint roller are expedient for processing color, several must therefore be used Basic bodies are provided in different lengths, on which the respective tubular body is then pushed.
- the paint roller according to the invention has the advantage over the known devices that, on the one hand, it is also designed as an environmentally friendly paint roller, ie. H. the paint roller provides a basic body that is always reusable, including the paint roller bracket.
- the paint roller according to the invention can be constructed in a modular system due to the very simple dismantling of its base body, so that the most varied parts of the base body can be used for all possible lengths of a paint roller.
- the disposable body consisting of a tubular body with an applied roller cover, can be provided in a wide variety of lengths as cut-to-length goods, in which the components of the rest of the main body are optionally used.
- This technique presupposes that the basic structure of the base body is essentially constructed as components that are independent of the length of the paint roller, so that these components are readily available for different lengths of the paint roller in the manner of the modular principle.
- the paint roller according to the invention contains a base body which can be dismantled and basically consists of the two separate end caps and additional additional means which, if necessary, have a supporting function in the form of stiffening ribs or a bearing function for the paint roller bracket within the tubular body in the form of additional pipes, if necessary, with adhesive sleeve bearings.
- the outer tube body can exist as an endless extruded plastic tube, which is shortened to the desired length.
- the inner body and the paint roller bracket are then inserted into the tubular body.
- the components of the base body then have to be adapted essentially in diameter to the inside diameter of the tubular body and to the dimensions of the bracket.
- Fig. 1 shows in Fig. 1.1 a paint roller in side view, which consists of a roller body 2, on which a multi-angled Paint roller bracket 3 is attached with a handle 4.
- Fig. 1.2 from Fig. 1 shows a section along the section line II in Fig. 1.1.
- the roller body 2 shown in Fig. 1.2 in longitudinal section consists of a cylindrical tubular body 5, on which a roller cover 6 made of plush, fur, foam or the like is applied in a known manner.
- the tubular body 5 is made of an extruded plastic material, the length l 1 being deflected as desired, the effective length of the roller body.
- the separate tubular body 5 and the roller cover 6 are designed as disposable parts after one or more uses.
- the paint roller according to the invention has, in the interior of the tubular body 5, a base body 7 which consists of components which are fundamentally reusable after use.
- this base body consists of two end caps 8, 9, which are identical or almost identical in their structure.
- the end caps 9 have a cup-shaped shape with a cylindrical outer wall 10, which are adapted in their outer diameter d 1 to the inner diameter d 2 of the tubular body 5.
- the end caps 8, 9 have a cylindrical inner tube extension 11 which extends over a length l 2 (see FIG. 1.4).
- the inner tube extension 11 of each end cap 8, 9 has an inner diameter d2, which is adapted to the outer diameter d3 of the paint roller bracket 3 inside the roller body or in the region of its bearing points.
- the cylindrical end caps 8, 9 also have star-shaped inner ribs or stiffening ribs 12, as shown in FIGS. 1.2-1.4. At the end of the stiffening ribs 12, these form a cylindrical bearing point 13 into which an adhesive disc 14 is inserted in a form-fitting manner. As from Fig. 1.2 and 1.4 As can be seen, the cylindrical bearing point is U-shaped in cross section, a shoulder pin 15 having a mounting bevel 16 for inserting the adhesive disc 14. 1.5 and 1.6 is designed as a non-slotted disc and has internal grooves 17 and clamping webs 18 for axially securing the paint roller bracket 3.
- each end cap 8, 9 On its outer circumference, each end cap 8, 9 has axial or tangential circumferential grooves or grooves 19 which serve for better clamping of the end caps in the tubular body 5.
- the length of the paint roller bracket 3 within the roller body is dimensioned such that it passes through both end caps 8, 9 at the corresponding bearing points in the inner tube extension 11.
- the end cap 9 can be completely closed on its outer end face or optionally provided with a predetermined breaking point 20 which is broken open as soon as the paint roller bracket is to be inserted from this side.
- the end caps 8, 9 and the paint roller bracket 3 can be easily removed from the tubular body 5 after use.
- the paint roller bracket 3 can be pulled out of the end cap 9 shown on the left in the figure, and the end cap can be knocked out by means of a simple tapping movement by means of the paint roller bracket.
- the paint roller bracket can then be pushed into the interior of the tubular body 5 from the other side and the other end cap 8 can be driven out.
- the length l 1 of the tubular body can be chosen arbitrarily. It is only necessary to ensure that the paint roller bracket in the interior of the roller body is sufficient has axial length. Possibly. the paint roller bracket on the side of the end cap 9 can protrude beyond the roller body.
- the paint roller according to Fig. 1 can be designed such that largely components from a kit can be used for a wide variety of sizes. Only the diameter of the tubular body and the end caps have to be adapted to one another.
- the paint roller according to FIG. 1 has the described stiffening ribs 12 only in the area of the end caps, this can also be suitable for larger length dimensions with a correspondingly thick-walled tubular body 5 since the tubular body 5 does not bend despite the lack of stiffening ribs. With shorter length dimensions, the wall thickness of the tubular body can be made correspondingly thinner. Furthermore, a known, slotted adhesive sleeve can also be used as an axial securing device for the bracket 3 instead of the adhesive disk 14.
- the paint roller 1 shown in FIG. 2.1 is shown in longitudinal section in FIG. 2.2.
- the outer tubular body 5 has a removable roller cover 6 as a disposable part, the two ends 21 of which are folded over into the interior of the tubular body in order to fix it.
- the roller cover 6 shown in FIG. 2.3 is accordingly longer than the length of the tubular body 5, the folded end 22 being clamped between the end caps 8, 9 and the tubular body 5.
- the outer diameter d 1 of the end caps 8, 9 is therefore made smaller by approximately the amount of twice the wall thickness s 1 of the plush cover than the inner diameter d 2 of the tubular body 5.
- the end caps 8, 9 are also cup-shaped in the embodiment according to Fig. 2, as described in Fig. 1.
- the inner tube extension 11 of the end cap 8 in turn serves to support the paint roller bracket 3.
- the inner tube extension 11 'of the end cap 9' serves as a bearing for the end of the paint roller bracket as shown in FIGS. 2.2 and 2.5.
- the inner tube extension is only tubular in its end region for receiving the paint roller bracket.
- the remaining part of the inner tube extension is designed as a closed rod 23. As a result, the outer contour of the end cap 9 'is closed.
- the base body 7 of the exemplary embodiment according to FIG. 2 is provided with an additional inner tube 25 which extends to the end regions of the Inner tube lugs 11 is pushed as a centering. As a result, the roller bearings are centered.
- the length l3 of the inner tube 25 extends to the stiffening ribs 12 of the end caps 8, 9, so that the inner tube 25 is supported against the stiffening ribs 12 of the two end caps 8, 9.
- the length l4 of the tubular pins of the extension tube 11 projecting into the tube 25 is dimensioned such that adequate centering and stabilization is achieved.
- the inner diameter of the inner tube lugs 11 corresponds to the outer diameter d3 of the paint roller bracket.
- the paint roller bracket 3 is axially secured by an additional adhesive sleeve 26 in the interior of the inner tube 25, a circumferential inner web 27 of the tube 25 engaging in a form-fitting manner in a corresponding circumferential outer groove 28 of the adhesive sleeve 26.
- Radial stiffening ribs 29 which radially support the tubular body 5 can be placed on the inner tube 25.
- the inner tube 25, the stiffening ribs 29 and the tubular body 5 can also be formed in one piece as a reusable part.
- the end caps 8, 9 and 9 ' can be designed completely independently of the length of the paint roller to be used in their shape. Only the inner tube 25 with possibly attached ribs 29 is to be adapted to the length l 1 of the paint roller, the distance l 1 of the end caps 8, 9 to be used up to the stop surface 30 being taken into account.
- the roller cover 6 can accordingly also be formed as the only part to be replaced, i. H. the tubular body 5 with ribs 29, inner tube 25 and end caps are designed as reusable parts.
- the roller bearings formed by the end caps can be easily dismantled by means of the paint roller bracket, so that the components as a whole can always be reused.
- the exemplary embodiment of the invention according to FIG. 3 provides an alternative embodiment of the base body 7 compared to the exemplary embodiment according to FIG. 1. Otherwise, the same parts are identified by the same reference numerals. Accordingly, the outer tubular body 5 is provided with a roller cover 6, these parts being firmly connected to one another as disposable parts. 3.2, the inner, always reusable base body 7 initially consists of the two end caps 8, 9, the end cap 8 again having a cup-shaped basic shape, with outer wall 10, inner tube extension 11 and intermediate stiffening ribs 12. The Inner tube extension 11 in turn serves as a bearing for the paint roller bracket 3.
- the opposite end cap 9 has no bearing function for the paint roller bracket. Accordingly, it consists only of the outer wall sections 10 and the continuous reinforcing ribs 12 'without an additional inner tube extension.
- the latter has two inner tubes 31, 32 tapering in the shape of a truncated cone towards the roller center 30, which form a cylindrical jacket tube 33, 34 in their outer region.
- the cylindrical outer casing 33, 34 has an outer diameter and an inner diameter such that it can be clamped exactly between the end caps 8, 9 and the tubular body 5.
- the end faces of the frustoconical inner tubes form a spherical bearing 34 for a correspondingly adapted spherical adhesive sleeve 35.
- the bearing surface 37 of the spherical bearing 34 directed towards the longitudinal center line 36 accordingly has a circumferential spherical curvature with the radius r, i.e. H. the bearing surface forms a circumferential convex curvature of a section of a circle.
- the axial width b1 of the bearing surface is dimensioned such that good guidance of the spherical adhesive sleeve 35 is ensured.
- the spherical adhesive sleeve 35 also has a circumferential concave, circular in cross-section bearing surface 38, which includes an undercut 39 with the width b3 in the central region. 3.3 and 3.4, the adhesive sleeve 35 is formed in a manner known per se with a longitudinal slot 40, so that it sits firmly on the paint roller bracket 3.
- this inner tube which is formed in one piece with the spherical bearing 34, can be pushed into the tubular body 5 in a force-fitting and positive manner.
- the end caps 8, 9 are then pressed laterally into the cylinder sections 33, 34.
- the inner tube thus formed is flexibly designed as an inner base body. Due to the spherical design of the bearing, even with tilting movements of the paint roller bracket, a uniform contact pressure is exerted on the adhesive sleeve serving as a bearing, ie. H. the contact pressure is evenly distributed due to the spherical design.
- the base body 7 is again designed as an exchange part, wherein the base body 31, 32 with end caps 8, 9 can be easily removed from the outer tubular body 5.
- the paint roller shown in Fig. 4.1 is shown along the section line I-I in Fig. 4.2 in longitudinal section.
- the roller body 2 in turn consists of the tubular body 5, which is designed as a deflected, extruded, smooth plastic tube and on which the roller cover 6 is applied in a manner known per se.
- the tubular body 5 and the roller cover 6 are designed as single or reusable disposable parts.
- the inner base body 7 in turn serves as a reusable part for further tubular bodies to be retrofitted with a roll cover.
- the base body 7 again consists of two end caps 8, 9, which are designed as simple cylindrical disks.
- the end caps 8, 9 are exactly on the outside diameter Adjusted inner diameter of the tubular body 5 in its end region.
- the cylindrical end cap 8 has a central bore 41, which is adapted in its diameter such that either an additional adhesive sleeve 42 for storing and axially securing the paint roller bracket 3 (see Fig. 4.2) or an immediate storage of the paint roller bracket 3 takes place in this bore 41 (see Fig.4.4).
- an additional locking washer 43 is provided behind the wall of the end cap 8 as an axial securing means.
- the opposite end cap 9 is designed as a closed cylindrical end cap which has only one bearing bore 44 for the paint roller bracket which engages there.
- a reinforcing rib arrangement 45 is located within the tubular body 5 for its support, as can be seen from FIG. 4.3 along the section line II-II from FIG. 4.2.
- the three star-shaped reinforcing ribs 29 of the rib arrangement 45 are integrally connected to the two end caps 8, 9, so that an inner support tube is unnecessary.
- the reinforcing ribs 29 rest with their radial outer edges 46 at three points as support surfaces 47 on the tubular body 5. In this respect there is no internal bracing of the rib arrangement.
- the rib arrangement In the area of the end cap 8, the rib arrangement has a circular cylindrical recess 48 in order to create space for the adhesive sleeve 42 or the locking ring 43.
- the arrangement according to FIG. 4 is disassembled by pulling the paint roller bracket 3 out of the bearing bore 44 and then pushing out the inner base body.
- the outer tubular body with roller cover can therefore be easily separated from the inner one Basic body are removed.
- the base body itself is in turn constructed as much as possible in a modular system, so that the end caps 8, 9 with molded ribs 29 can be used for all length dimensions of such a paint roller with the same diameter. Due to the simple disassembly option, the base body 7 can always be reused without any problems.
