Definitions

• the invention relates to a paint roller according to the preamble of claim 1.
• Conventional paint rollers consist of a cylindrical roller body, hereinafter also referred to as a roller or paint roller, with an inner cylindrical tube body which serves to receive a roller cover made of plush, fur or foam or the like.
• a slotted, radially widening clamping sleeve is generally provided in the interior of the tubular body.
• the clamping sleeve is secured against axial displacement on one side in the tubular body by a corresponding projection. On the other side in the direction of the tube body opening, an end piece is snapped in to prevent the sleeve from falling out.
• the end piece such as the clamping sleeve
• both individual parts serve to receive and mount a support bracket to be inserted into the roller body.
• the clamping sleeve has the task of axially fixing the roller body on the support bracket.
• the bracket is usually composed of a bent metal wire and a plastic handle at the lower end.
• the paint roller which is often thrown away after use, requires several individual parts, which not only increase the cost of production, but are also undesirable from an environmental point of view.
• the structure of the support bracket as a combination of metal and sprayed-on plastic can only be used with great effort in a raw material recovery.
• the carrying bracket is not sufficiently stable for practical use.
• the invention has for its object to provide a paint roller with a one-piece plastic bracket, which has a stiffness comparable to a conventional bracket made of metal wire, for example, using little material and at low manufacturing costs. Furthermore, a simple and effective and at the same time universal fastening possibility between the support bracket and the roller body is to be ensured. This object is solved by the features of claim 1.
• the invention is based on the fact that the paint roller consists of a one-piece plastic support bracket provided with a handle and a paint roller which can be rotatably attached to the front end of the support bracket.
• the main idea now lies in the fact that the support bracket comprises at least partially transverse stiffening elements over its length, which are connected to one another in a stiffening manner by means of a longitudinal strut. In this way, an excellent stiffness is achieved with a low weight, similar to the ribbing of an aircraft wing made of frames and spars. It is therefore not necessary to use a plastic that is, for example, fiber-reinforced, which leads to reduced manufacturing costs. In addition, the fact that comparatively less material is required for production contributes to a further reduction in costs.
• the light weight of the construction of the support bracket has the advantage for a user of being less tired when carrying out lengthy work.
• the stiffening In order to make the stiffening particularly efficient, it is also proposed to implement the longitudinal bracing by means of wall sections. It is particularly preferred to design the wall sections as an open hollow profile and in particular as a half-shell. In the case of a hollow profile, the stiffening elements are expediently attached to the inside thereof.
• the transverse ones are proposed below To allow stiffening elements to protrude at least in the area of the handle on the open side of the hollow profile.
• the spatial shape of the handle is thus defined on the one hand by the outer contour of the hollow profile and on the other hand by the shape of the stiffening ribs. It is advantageous that the stiffening elements have a distance of 2 to 6 mm in order to avoid pressure points in the user's hand.
• the spacing of the stiffening element arranged outside the handle be greater than that of the stiffening elements attached in the region of the handle.
• the width and / or the cross section of the hollow profile be reduced continuously or at least in sections from the handle to the front end of the support bracket.
• the front part of the support bracket in front of the receiving area of the paint roller is also proposed to design the front part of the support bracket in front of the receiving area of the paint roller as a U-shaped profile. This area is preferably also ribbed to increase stability.
• the front area of the support bracket is also formed directly as a roller bearing for a roller body, which is also referred to here as a paint roller or roller.
• a roller bearing for a roller body which is also referred to here as a paint roller or roller.
• the clamping sleeve described in the prior art and the end piece for fixing the clamping sleeve for realizing the roller bearing in the present invention can preferably be integrally formed on the front end of the mounting bracket.
• the supporting bracket can therefore be designed in its end region such that it engages in a groove or the like provided on the inside of the tubular body such that the tubular body rotates on the supporting bracket itself.
• the paint roller be designed to snap onto the roller bearing at the front end of the support bracket. It is advantageous if the roller bearing has a latching web for engaging in a circumferential groove in the tubular body of the paint roller.
• the dimensions of the latching web and groove are preferably to be set so that the paint roller is rotatable about its longitudinal axis. A mutual exchange of the snap-in web and the groove on the respective parts may be advantageous.
• At least one additional bearing web can be provided on which the tubular body of the paint roller can slide and is supported against tilting.
• a limiting web is provided on the roller bearing for the end of the rotatably mounted paint roller on the support bracket side.
• the limiting web prevents paint from penetrating into the tube body of the roller.
• This also defines the installation path, ie the insertion length can be specified.
• the connection between the roller bearing and the tubular body is made via a separate clamping sleeve or adhesive sleeve, which has the corresponding latching means in its inner tube surface.
• a simple cylindrical tube body can be used in the appropriate length, into which the clamping sleeve is inserted by a simple press fit.
• FIG. 1 shows a support bracket of a paint roller according to the invention in front view
• FIG. 3 shows the support bracket from FIG. 1 in the view from behind
• FIG. 5 shows a first tubular body according to the invention for a paint roller or roller in longitudinal section
• FIG. 6 shows a second tubular body for a roller in longitudinal section
• Fig. 7 shows the enlargement of detail VII from Fig. 5 and Fig. 6 and
• FIGS. 1 to 3 A first exemplary embodiment of a support bracket according to the invention for a paint roller is shown in FIGS. 1 to 3 and the associated cross sections in FIGS. 4a to g.
• the cross sections in Figures 4a to g are shown on a scale of 2: 1.
• the bracket 1 is made in one piece from plastic. It comprises at its lower end a handle 2 and at its upper end an approximately perpendicular to the handle roller bearing 4. In between is a curved connecting part 3.
• the connecting part 3 and the handle 2 are essentially by a hollow profile 5 open on one side (see the Cut profiles in FIGS. 4a to b) are formed.
• the hollow profile 5 is stiffened by transverse ribs 6.
• Ribs or stiffening elements along the section line EE or FF are shown as examples in FIGS. 4e and 4f.
• the stiffening elements 6 are arranged at a comparatively narrow distance a of preferably 3 mm (see in particular FIG. 4g).
• the stiffening elements 6 are on the open side of the hollow profile 5 over this, so that on one side by the hollow profile 5 and on the other side by the outer edges of the stiffening elements, the spatial shape of the handle 2 is defined (Fig. 2).
• the outside of the hollow profile is ribbed in the region of the gripping surface 7 of the handle 2 in order to improve the gripping quality.
• transverse ribs or stiffening elements 7 are provided in the hollow profile 5 for stiffening.
• the distance between the stiffening elements is, however, significantly larger than in the area of the handle 2.
• the stiffening elements do not protrude beyond the open side of the hollow profile.
• the last transverse rib of the handle 2 and all further subsequent transverse ribs 8 of the connecting part 3 are connected by a longitudinal web 9 running in the central region of the hollow profile (see in particular the sectional diagrams 4c and 4d).
• the stiffening by the longitudinal web 9 and the stiffening elements 8 does not, however, take place over the entire area of the connecting part 3, but only from the handle via a first bend to the area of the next bend that follows.
• the hollow profile 5, which has tapered in cross-section up to that point runs with an unchanged width or cross-section up to the roller bearing 4 in the form of a U-profile without additional stiffening elements (compare the cross-sections in FIGS. 4a and 4b) to the roller bearing 4 further.
• this area can also be provided with additional stiffening elements.
• the roller bearing 4 at the end of the connecting part 3 is used for the direct accommodation and rotatable mounting of a cylindrical roller body with a corresponding roller cover.
• FIGS. 5 and 6 show such rolls without plush or foam cover, that is to say only by their tubular bodies 10, 11, to which the roll cover is to be attached.
• the tubular bodies 10, 11 are simply plugged onto the roller bearing 4 and locked in place.
• a circumferential locking web 12 on the roller bearing 4 slides along a cone 13 on the inside of the tubular body 10, 11 into a also on the inside of the tubular body 10, 11 circumferential groove 14.
• the dimensions of the latching web 12 and the groove 14 are determined so that the latching web engages in the groove, but nevertheless enables a rotation of the tubular body and thus the roller in the direction of the groove becomes.
• the latching web 12 is positioned approximately centrally on the roller bearing 4. At a distance from each other further webs 15, 16 are arranged on recessed connecting elements 17, 18 or connecting cylinders.
• the cutouts 22 serve to save material.
• the webs 15, 16 form a bearing for the tubular body 10 or 11, on which it slides during a rotational movement and is supported against tilting forces. This is particularly important if, as in the case of the one shown in FIG. 6, the tubular body protrudes far beyond the roller bearing 4 in the attached state.
• the tubular body 11 is, for. B. twice as long as the tubular body 10 and due to its symmetrical construction on both sides of the roller bearing 4 can be plugged and locked.
• the strut elements 19 in the middle of the tubular body 11 are again shown enlarged in detail VIII in FIG. 8. They also serve as a stop for movement of the roller body 4 within the groove 14 in the axial direction.
• a limiting web 20 is provided on the inner edge of the roller bearing. This can also take on the task, for example, of closing the tubular body 10, 11 against the entry of paint, insofar as the other side of the tubular body is sufficiently closed by the roller cover. Furthermore, the web 20 represents a path limitation during assembly.
• a variant of the invention provides that the tubular body 10, 11 is not itself designed in its respective end region as an "adhesive sleeve" or “clamping sleeve” for the roller bearing 4, but a separate part is provided for this. 9 accordingly shows a separate adhesive sleeve or clamping sleeve 21, which in principle has the same structure as the tubular body according to FIG.
• roller bodies 10 ', 11', or the ink roller is introduced with a press fit or the like.
• another part adheresive sleeve
• normal cylindrical tubes to be cut to length can be used as roller bodies, which can optionally be covered with plush or foam.
