Abstract

The scraper comprises a handle 10 leading to a head 12 receiving the metal scraping blade 16. A cover 22 is adapted to snap over the end of the head and cover the scraper blade edge 24. <IMAGE>

Description

SPECIFICATION Improvements relating to hand tools This invention relates to hand tools, and in particular relates to paint scrapers of the type having a head for holding a metal blade of elongate form, on one of the longer edges of which is the scraping edge, and the blade is inserted laterally into a head of the tool and is held frictionally therein with the said scraping edge projecting beyond the head. The scraping edge is normally a sharpened, ground edge, and therefore when the tool is not in use the scraping edge must be covered by a cover member.
The head is connected to a handle portion by which the tool is manipulated.
Such tools are well known and are in extensive use, and typically the head at least and usually the head and handle are moulded by an injection moulding process in plastics material. Because of the moulding operation, there is a need to provide an aperture in the moulding in the region of the head, in order that the head can be removed from the mould, and the present invention is concerned with a novel and effective utilisation of the aperture formed in the head, or several such apertures, and in accordance with the invention, a cover for the scraping edge of the blade has an extension which overlaps a portion of the head, and an inner projection springs into said aperture when the cover for the scraping edge is applied, thereby resiliently to keep the cover in position.To remove the cover it is necessary to bring the projection out of the aperture in the tool head, and therefore it is preferred that the cover be formed in plastics material.
The invention achieves the improvement that as compared to the known arrangements, there is no tendency for the cover simply to fall off when the tools are hung, for example, for display or storage purposes. In the conventional arrangements, the covers are simply friction fitted on the projecting edge of the blade.
It is preferred that the handle and head be formed as a one-piece moulding, the handle being an elongated portion leading to the head at one end which is generally triangular in configuration, but lies in a plane which is inclined relative to the axis of the handle thereby to ensure that the tool when held naturally will present the blade at the correct attitude for scraping the surface to be cleaned.
Preferably the head has two of said holding apertures, and the extension has two of said projections which respectively spring into the apertures and retain the cover when the cover is applied over the blade.
An embodiment of the present invention will now be described by way of example, with reference to the accompanying diagrammatic drawings, wherein: Figure 1 is a perspective view of a hand tool according to the invention, but with the respective parts being shown in exploded condition; Figure 2 is a perspective view of the underside of the cover showing the catching projections; and Figure 3 is a sectional elevation taken through the line Ill-Ill in Fig. 1, but with the tool in assembled condition.
Referring to the drawings, the tool comprises a one-piece moulding defining a handle portion 10 and a head portion 12. The handle portion 10 is elongate, and at one end is provided the head portion 12. The head portion 12 is generally triangular in shape, and it lies in a plane which is inclined to the axis of the handle. The head has a recess 14 (Fig. 3) for receiving a blade 16, and the top surface of the head is provided with two apertures 18, 18, which are necessary for the moulding operation. The blade simply slips into the recess 16 as shown in dotted lines so as to project from the head edge 20 and be suitable for manipulation against the surface to scrape same or paint or the like.
The cover 22 which is essentially to cover the sharp edge 24 of the blade has an extension 26 to the underside of which are two projections 28 which when the cover is pushed into position over the head and covering the blade edge as shown in Fig. 3, spring into the apertures 18 in the head surface and retain the cover 22 in position until it is forced from the head by pressing with the thumb on the formation 30 provided on the cover 22.
By this means, the cover 22 snaps into position over the head, and only by springing the projections 18 out of the apertures 28 will the cover be removed.
The advantage of this arrangement is that the cover will not fall off accidentally as happens in the case of the prior art arrangement in which the cover is only friction fitted on the blade.
