Abstract

A garden sieve for mounting on a wheelbarrow has a frame 10 and a foot or stand 18 adapted for detachable connection by means of selectively engageable projections and recesses, with the frame in any one of a series of positions whereby the extension and/or angular position of the foot relative to the frame is adjustable. In the preferred embodiment the foot has two arms the free ends of which engage opposite sides of the frame near one end thereof and the other end of the frame carries clips 16 intended in use, to fit over an edge of the wheelbarrow. <IMAGE>

Description

SPECIFICATION A garden sieve This invention relates to a sieve and more particularly to a garden sieve for mounting on a wheelbarrow.

According to this invention we propose a sieve for mounting on a wheelbarrow, comprising a frame and a foot or stand adapted for detachable connection with the frame in any one of a series of positions whereby the extension and/or the angular position of the foot relative to the frame is adjustable. In a preferred embodiment, the foot has projections or recesses at intervals along its length and the frame has complementary recesses or projections, adjustment of the relative disposition of the frame and the foot being possible by engaging selected projections and recesses.

An embodiment of this invention will now be described by way of example with reference to the accompanying drawings of which: Figure 1 is a perspective view of an assembled garden sieve according to the invention; Figures 2a-d comprise respectively elevation, end elevation, plan and perspective views of the frame of the sieve shown in Figure 1; Figure 3 is a perspective view of one of the two clips shown in Figure 1, for attaching the sieve to the front edge of a wheelbarrow; Figure 4 shows the adjustable foot used to support the sieve of Figure 1 in a desired inclined position above a wheelbarrow; Figure 5shows a modified form of foot; Figure 6 is a perspective view of a plate that can be temporarily affixed to the frame of the sieve shown in Figure 1; Figure 7 is a perspective view showing the method of affixing the plate to the frame; and Figure 8 is a perspective view of another embodiment sieve according to this invention.

The garden sieve shown in Figure 1 is made up of six parts; a frame 10, a sheet 12 of wire mesh, a Z-shaped reinforcing rod 14, two spring clips 16 and a foot 18 for adjusting the height and inclination of the sieve.

In order to strengthen the frame 10 which as seen from Figure 2 is open at one end, the Z-shaped rod 14 is secured by welding or otherwise, to its bottom edge 20 and serves also to support the wire mesh 12 in the middle of the frame.

Each spring clip 16 has a hollow spine 22 from which extend leaves 24 and 26, the clips being fitted onto the rod 14, where it crosses between the two side walls 28 and 30 at the open end of the frame 10, such that the clips are pivotable on the rod 14, which is received in the hollow spine, to permit the clips to be fitted over the edge of a wheelbarrow (not shown in Figure 3) at any desired inclination.

Adjustment of the inclination and/or height of the sieve is achieved by means of a series of spigots 30 spaced at intervals along the free end portions 32 of the foot 18 (see Figure 4), which engage holes 34 formed in the side walls 28 of the frame. In each side wall, the arrangement of holes is identical, there being four holes of which three are angularly spaced along the circumference of a circle the centre of which coincides with the fourth hole. The radius of this circle, that is to say the distance between the fourth hole and each of the others, is equal to the centre distance between adjacent spigots 30 on the foot, so that in any one of the three angular settings of the frame relative to its support, two spigots 30 engage in holes 28 on each side of the frame.

At least the fourth hole is fitted with a bush 36 to strengthen the connection with the fast but in Figure 2 such bushes are fitted in all holes 34. It will be appreciated that a similar effect is achieved if the arrangement of holes 34 is inverted; that is to say if the fourth hole is uppermost.

In use, the frame 10 is placed on top of the wheelbarrow with the spring clips 16 fitted over the edge of the front wall the foot 18 resting against or standing on the side walls, the inclination and height of the sieve being determined by the engaement of selected spigots and holes. If further adjustment is required the foot may have more spigots or a taller foot such as shown in Figure 5.

Figures 6 and 7 show details of a modified embodiment of garden sieve comprising an optional seventh component, namely a plate 40 which acts as a temporary collector of course material, such as stones, obtained by separating coarse from fine material in the sieving process. The plate 40 may be freely affixed to, and disconnected from the open end of the frame 10 of the sieve during use.

The plate 40 has one or more brackets 42 at each end affixed by welding or other means. The brackets 42 fit to the lips 44 of the front of the side walls 28,30 of the frame 10. The bottom edge 46 of the plate sits on top of the Z-shaped rod 14 and/or the sheet of wire mesh 12 in the gap formed by the open end of the frame 10.

In an alternative embodiment, the spring clips 16 are welded or otherwise affixed to the Z-shaped reinforcing rod or to the front of the bottom edge 20 of the frame as shown in Figure 8.

Further the frame 10 may have an inwardly projecting lip or flange around its bottom edge. The periphery of the wire mesh sheet 12 is affixed by welding or clamping or in any suitable manner either on top of the lip (i.e. within the frame) or to the underside thereof.
