Description

DECORATING TOOL This invention relates to a mounting for a paint roller, the mounting comprising an elongated member having a pair of side end portions which extend substantially at right angles to the main portion of the member and which in use carry an axle pin or pins respectively which in use extends through or into an aperture or apertures in the roller to support the roller for rotation, the portions of the member carrying a tubular component which can be held by the user or into which a handle can be secured.

The pin or one of the pins is detachably secured to one of the side end portions to enable the roller to be replaced. Various ways are known for securing the pin to the side end portion. In one such way the pin is provided with a head which locates against the outer side of the side end portion and a split pin is passed through a drilling in the pin. In another way the pin is provided with a screw threaded portion which is engaged in a screw threaded aperture in the side end portion. In this case a screw driver is required to disengage the pin and considerable effort may be required if the screw threads have become clogged with paint.

The object of the present invention is to provide a mounting for a paint roller in a convenient form in which changing of the roller can be readily effected.

According to the invention a mounting of the kind specified comprises a clip which can be detachably secured to one of the side end portions, said clip having a portion engageable with the adjacent end of the axle pin to prevent the pin disengaging from the roller.

An example of a mounting in accordance. with the invention will now be described with reference to the accompanying drawing in which: Figure 1 is a perspective view of the mounting with a paint roller carried therein.

Figure 2 is a perspective view to an enlarged scale showing two parts of the mounting.

Figure 3 is a section through part of the mounting seen in Figure 1, Figure 4 is a section through a further part of the mounting of Figure 1 and, Figure 5 shows a modification to the mounting.

Referring to the drawings the mounting comprises an elongated member 10 which as will be seen, extends in parallel spaced relationship to the roller which is generally indicated at 11. The elongated portion is provided with integral side end portions 12 which extend adjacent the ends of the roller. Conveniently the member 10 and the side end portions 12 are formed from steel rod which is bent to the required shape. The roller 11 is of conventional construction comprising a substantially cylindrical plastics member about which is secured the paint conveying material. The roller is provided with a central aperture through which extends an axle pin 14.

The axle pin 14 is formed from steel rod having a diameter less than the diameter of the rod forming the member 11. The side portions 12 are each provided with through apertures to accommodate the axle pin 14 and in order to retain the axle pin in position a clip 15 is provided, the clip being shown in isolation in Figure 2 and in its operative position and engaged with one of the side portions 12 in Figure 1.

The clip 15 is formed from spring steel strip and is of elongated form having a web portion 16 in which adjacent one end is formed a generally rectangular aperture 17, the aperture extending in the longitudinal direction of the web portion. Along one longitudinal edge the web portion is provided with a narrow flange 18 which at its end remote from the aperture is extended to form a clip portion 19 and adjacent the aperture is extended to form a locating portion 20. The locating portion 20 extends in the plane of the web portion and is then bent generally to the radius of the rod forming the side portions 12. The clip portion 19 also extends in the plane of the web portion and is also bent to the radius of the rod forming the side portions 12 but in this case the bent portion is extended so as to provide the required clip action.The bent portion terminates in an outwardly extending tab 21 to facilitate manual disengagement of the clip. The clip portion 19 is shown in engagement with a side portion 12 in Figure 2 and it will be seen that the web portion 16 is held in engagement with the side portion 12.

The axle pin 14 at one end is provided with a tongue 22 which is formed by deforming the end of the rod forming the axle pin in a press. The thickness and the width of the tongue 22 are such that the tongue can pass through the aperture 17 but the width of the tongue is such that it cannot pass through the apertures in the side portion 12. In the assembled condition therefore the axle pin cannot move in one direction due to the interference between the tongue and the aperture in the side portion 12 and it cannot move in the opposite direction due to the engagement of the end portion of the axle pin on the opposite sides of the tongue with the web portion 16 of the clip.

In order to change the roller 11 the clip 15 is moved angularly about the axis of the axle pin until the locating portion 20 of the clip is free of the side portion after which the clip can be removed,and then the axle pin is withdrawn to allow the roller to be changed.

The parts are then assembled in the re verse order.

In an alternative construction the clip is secured to the end of the axle pin. In this case the aperture in the web portion of the clip is circular to accommodate a reduced section of the axle pin which projects through the aperture and is deformed in the manner of a rivet.

Secured to the elongated member 10 is a tubular component 23 which is conveniently formed from a length of hexagonal steel bar 24 which is welded to the member 10. The bar 24 is provided with a stepped through bore conveniently formed by drilling through the bore with a first drill and then partly drilling through the bore with a slightly larger drill. The narrower portion of the bore is at the end of the bar which is secured to the member 10. In use, the tapered end 25 of a handle is inserted into the bore and is wedged therein.

The component can be formed in other ways for example, the bore in the component can be a plain bore and the end of the component which is attached to the member 10 can be deformed to provide ears which extend into the bore for engagement with the tapered end of the handle. As an alternative the bore in the component can be formed with a screw thread for engagement by the threaded end of the handle.

Although as shown the axis of the tubular component 23 extends parallel to the plane containing the elongated member 10 and the side portions 12 it will in practice, be inclined to the plane at an angle for example 450.

Figure 5 shows an alternative way of securing the axle pin 14 relative to one of the side portions 12. In this case one end of the axle pin is provided with a notch 25 and the side portion 12 is provided with an aperture 26 which extends at right angles to the aperture 33 for the axle pin but the axes of the two apertures are axially displaced so that with the axle pin inserted in the aperture 33 the end portion 28 of a wire clip 27, inserted into the aperture 26 will locate in the notch 25 to secure the axle pin against axial movement. The clip 27 is provided with a portion 29 which extends in use adjacent the side portion 12 and a clip or hook portion 30 which engages about the side portion.

It will be understood that the axle pin can be formed in two parts with one part secured to one of the side portions and the other part detachably retained in the other side portion as described.

By the constructions described the mounting can be formed entirely from steel components and therefore has substantial strength and can be constructed using simple tools.
