Description

[0001] The invention relates to a paint roller according to the preamble of patent claim 1.

[0002] Such a paint roller is known, for example, from DE 10 2007 030 632 B3. This known paint roller features a side protection plate covering the exposed end of the paint roller. The side protection plate limits the paint application at the sides and enables a straight and clean painting edge. The side protection plate is attached to a swivel bracket and can be pivoted from a working position adjacent to the end of the paint roller to a roller-changing position remote from the end by pivoting the swivel bracket. In the roller-changing position, the roller body can be removed from the retaining bracket and replaced with a new roller body.

[0003] To move the side protection plate from the working position to the roller change position, it is necessary to grasp the swivel arm with your hand. This can result in harmful dirt from paint adhering to the swivel arm.

[0004] DE 1 277 082 A and the corresponding DE 1 935 417 U disclose a paint roller with a handle, at one end of which a side protection plate is provided to cover a free end of the roller body. The other end of the handle is attached to a grip, which is rotatably movable relative to a handle and longitudinally movable parallel to the handle.

[0005] The object of the invention is to eliminate the disadvantages of the prior art. In particular, it is intended to provide a paint roller in which the side protection plate can be moved from the working position to the roller-changing position without soiling the hands.

[0006] This object is achieved by the features of patent claim 1. Advantageous embodiments of the invention emerge from the dependent patent claims.

[0007] According to the invention, it is proposed that the other end of the pivoting bracket is held in a device for converting a rotary movement into a pivoting movement, which can be actuated by means of a rotary handle which is rotatable with respect to an axis of the handle, wherein the device for converting a rotary movement into a pivoting movement comprises a holding element provided on the handle, in which a handle-side end of the holding bracket is held, wherein the holding element has a radially extending link in which the other end of the pivoting bracket is guided and can be pivoted outwards by turning the rotary handle, so that the side protection flap can be moved from the working position into the roller changing position.

[0008] Devices for converting a rotary motion into a pivoting motion are well known in the art. A component to be pivoted is typically guided in a slotted guide.

[0009] The term "handle axis" generally refers to the longitudinal direction of the handle. The handle can be rotationally symmetrical, at least in sections, but this is not required. The rotary handle is rotatable about the handle axis. The rotary handle is expediently arranged adjacent to the handle. The rotary handle is arranged on the handle in particular where the retaining bracket is connected to the handle.

[0010] By providing the device proposed according to the invention for converting a rotary movement into a pivoting movement, it is possible to move the pivoting bracket from the working position to the roller-changing position by simply actuating the rotary handle. For this purpose, it is no longer necessary to grip the pivoting bracket by hand. Undesirable contamination of the hand by paint adhering to the pivoting bracket can be avoided. Furthermore, the paint roller according to the invention can also be used like a conventional paint roller without a side protection plate when the pivoting bracket is in the "roller-changing position." The proposed rotating and pivoting movement of the pivoting bracket thus enables the paint roller to be "switched over" from a conventional paint roller to a paint roller with a side protection plate.

[0011] According to the invention, the device for converting a rotary movement into a pivoting movement comprises a holding element provided on the handle, in which a handle-side end of the retaining bracket is held. The holding element can be manufactured as a single piece with the handle. However, it can also be a separate component attached to the handle in a rotationally fixed manner. A tube expediently extends centrally from the holding element, into which the handle-side end of the retaining bracket can be inserted. The handle-side end can, in particular, be held in the tube by frictional engagement.

[0012] In the paint roller according to the invention, the side protection plate is expediently not only pivoted relative to the end face of the roller body, but also rotated around the axis by an angle in the range of 60 to 100°, preferably 85 to 95°. This makes it possible to press the end face of the roller body against a base in the tool change position, thereby triggering a "push-push mechanism" that holds the roller body to the holding bracket. Such a "push-push mechanism" is known, for example, from WO 2014 / 135227 A1. Furthermore, in the roller change position, it is possible to use the paint roller like a conventional paint roller without the side protection plate. By rotating the pivoting bracket around the axis in the roller change position, the paint roller can be used like a conventional paint roller without the side protection plate interfering.

[0013] According to an advantageous embodiment of the invention, the device for converting a rotary movement into a pivoting movement comprises a receptacle that pivotally holds the other end of the pivoting bracket and is rotatably supported on a support surface extending radially from the holding element. The tube expediently extends centrally from the support surface. The holding element can furthermore have a radially extending slotted guide. The slotted guide is expediently provided in the region of an opening edge of the tube. Advantageously, the receptacle is held between the slotted guide and the support surface. The receptacle can partially encompass the tube.

[0014] Furthermore, a rotary handle designed like a cap can be attached to the holding element. The rotary handle can have a circumferential cylindrical cap wall, on the inner circumference of which a circumferential web is provided, which engages in a groove provided on the holding element, so that the rotary handle can be rotated relative to the holding element.

[0015] Furthermore, the rotary handle can have an elongated hole, preferably on a lid section of the cap, through which the other end of the swivel bracket is guided. Finally, the rotary handle can have a central opening in the lid section for the grip-side end of the bracket to pass through. The opening is expediently aligned with the tube.

[0016] In the proposed design, the rotary handle together with the holding element forms a housing in which the receptacle is accommodated.

[0017] In the paint roller according to the invention, when the rotary handle is turned, the other end of the bracket and the pivotally connected holder rotate. The slotted hole in the rotary handle and the slotted guide on the holding element are coordinated so that when the rotary handle is turned, the pivoting bracket rotates and pivots simultaneously.

[0018] An embodiment of the invention is explained in more detail below with reference to the drawings. They show: Fig. 1 an exploded view of the paint roller, Fig. 2 a perspective view of the paint roller in the working position, Fig. 3 a perspective view of the paint roller according to Fig. 2 in the roll change position, Fig. 4 a perspective view of the paint roller in the working position with the rotary handle removed, Fig. 5 a perspective view of the paint roller in the roller change position with the rotary handle removed, Fig. 6 a schematic sectional view through the holding element, with the receptacle in the working position, and Fig. 7 a schematic sectional view through the holding element, wherein the holder is in the roll changing position.

[0019] In the figures, reference numeral 1 denotes a coat-hanger-shaped support bracket on which a roller body 2 is rotatably mounted in a conventional manner. Reference numeral 3 denotes a pivoting bracket, to one end E1 of which a side protection plate 4 is attached. Another end E2 of the pivoting bracket has a cylindrically undercut first groove 5.

[0020] Reference numeral 6 denotes a handle into which a holding element 7 can be inserted. The holding element 7 has a round support surface 8, from which a tube 9 extends centrally. A slotted guide 10 extends radially from an opening edge of the tube 9. Reference numeral 11 denotes a receptacle having a holding surface 12 corresponding to the support surface 8. Extending from the holding surface 12 are two opposing walls 13, between which the other end E2 of the pivoting bracket 3 is pivotally held.

[0021] A second groove 14 is provided on a circumferential edge of the support surface 8, which serves to rotatably guide a rotary handle 15. The rotary handle 15 is designed like a cap and has a circumferential cylindrical cap wall and a lid section. An elongated hole 16 is provided in the lid section, through which the other end E2 of the pivoting bracket 3 is guided. Furthermore, the rotary handle 15 has a central opening 17 in the lid section, through which a handle-side end E3 of the retaining bracket 1 is guided.

[0022] Fig. Figure 2 shows the paint roller in a working position. The side protection plate 4 is located adjacent to a front side S of the roller body 2.

[0023] At the Fig. In the roller changing position shown in Figure 3, the front side S is freely accessible. The pivoting bracket 3 is in an outwardly pivoted position relative to the rotary handle 15 or an axis of the handle 6. Furthermore, the pivoting bracket 3 is rotated by approximately 90° relative to the holding bracket 1.

[0024] Fig. Figure 4 again shows the paint roller in the working position, with the rotary handle 15 omitted here. The other end E2 of the swivel bracket 3 extends approximately parallel to the handle-side end E3 of the holding bracket 1 in the working position.

[0025] At the Fig. In the roller changing position shown in Figure 5, the other end E2 of the swivel bracket 3 rests against the guide 10. The other end E2 of the swivel bracket 3 is rotated by approximately 90° with respect to the handle-side end E3, which is firmly held in the tube 9, and is also pivoted.

[0026] The Fig. 6 and Fig. 7 show schematic sectional views in a cutting position between the two walls 13, wherein the cutting position runs parallel to the walls 13. A rod 18 extends between the walls 13 and is partially encompassed by the cylindrically undercut first groove 5. As a result, the other end E2 of the pivoting bracket 3 is pivotally held around the rod 18. Reference numeral 19 designates a circumferential web provided on an inner side of the rotary handle 15, which engages in the second groove 14 so that the rotary handle 15 is rotatably held on the holding element 7. The holding element 7, together with the rotary handle 15 locked thereto, forms a housing in which the receptacle 11 is rotatably received on the support surface 8.

[0027] The function of the paint roller is as follows: In the working position, the other end E2 of the swivel bracket 3 is forced against one end of the elongated hole 16. As a result, the side protection plate 4 covers the end face S of the roller body 2. When the rotary handle 15 is rotated relative to the handle 6, the other end E2 of the swivel bracket 3 is rotated. At the same time, the other end E2 rotates the holder 11. The other end E2 is guided along the guide rail 10 and pivoted outward. The other end E2 is guided through the elongated hole 16, the two walls 13, and the guide rail 10.

[0028] In particular in Fig.In the roller changing position shown in Figure 3, if a "push-push mechanism" is provided, the end face S of the roller body 2 can be pressed against a base to release the "push-push mechanism" and release the roller body 2 from the retaining bracket 1. After replacing the roller body 2, the side protection plate 4 can be returned to the working position by turning the rotary handle 15 in the opposite direction. In particular, it is not necessary to grasp the swivel bracket 3 by hand for this purpose.

[0029] Apart from that, the paint roller can easily be used like a conventional paint roller when the swivel bracket 3 is in the roller change position.
