Abstract

The front-entry aperture of a roadside kerb gully box overlying a drain can be closed to prevent ingress of sand etc in a dry season by repositioning a lift-out cover 6 to bring a depending solid rear wall of the cover into the location normally occupied by a depending front entry grid wall 10. The lift-out cover 6 has four horizontal supporting pins engaging frame slots 12, 13, shaped to allow rear hinge opening when required. <IMAGE>

Description

SPECIFICATION Improvements In or Relating to Gully Assemblies This invention relates to gully assemblies of the kind used for example, for road kerb openings for sewers and drains to receive rain and other surface water from the roadway.

The invention is particuiarly concerned with such gully assemblies suitable for use in areas of the world having well defined and separate wet seasons and dry seasons.

In areas of this kind, the problem arises that during the dry season not only is the gully assembly not required for use but it is highly susceptible to blocking by the ingress of sand or dust for example.

It is an object of the present invention to provide a gully assemble which overcomes or at least substantially reduces this problem.

According to the invention there is provided a gully assembly comprising a frame having generally upright side walls, at least one water inlet opening being provided in the side walls, and a cover arranged for seating upon the frame in two alternative positions in the first of which it exposes the water inlet opening in the frame and in the second of which it closes the water inlet opening in the frame.

The frame may be generally rectangular in plan view, and may be provided with upright walls upon three sides and be open on the fourth side.

In this case the cover may have a complementary rectangular plan configuration and may be provided on one side with a downwardly projecting wall and on the opposite side with a downwardly projecting grating. By this means, by reversing the seating of the cover upon the frame, the open side of the frame may be exposed through the downwardly projecting grating, allowing the ingress of water or the open side of the frame may be closed by the downwardly projecting wall preventing the ingress of sand or dust.

In order that the invention may be more readily understood one embodiment thereof will now be described by way of example with reference to the accompanying drawings, in which: Figure 1 is a partly cut away isometric view of a drainage gully according to the invention in the open position; Figure 2 is a partly cut away isometric view of the drainage gully of Figure 1 in the closed position; and Figure 3 is part sectional elevation of the drainage gully of Figure 1.

As can be seen in the drawings, the manhole assembly comprises a cast iron frame 1 of generally rectangular configuration in plan. The frame 1 is provided with upright walls 2 on three sides, the walls being-provided with a supporting flange 2 and ribs 4. The fourth side of the frame is open and is only provided with a spacing bar 5 connecting the lower edges of the adjacent side walls.

In use the frame is mounted in the pavement of a footway adjacent to a road. The upper edges of the upright walls 2 are disposed generally flush with the surface of the footway (not shown), and the open or forward side of the frame is disposed in line with the generally vertical kerb (not shown) between the footway and the road. The frame is located above an opening leading to a water drain (not shown).

A cover 6 is seated upon the frame 1, the cover comprising an upper plate 7, provided with slipreducing embossments 8, and two downwardly projecting side walls 9 and 10 on opposite sides of the plate 7. It will be noted that side wall 9 is blind in the form of a continuous plate like member whilst side wall 10 is in the form of a grating of downwardly projecting fingers.

The cover 6 is seated in the frame by means of four pins 11 which engage in slots 12 and 13 in opposite walls 2 of the frame 1. As shown in Figure 1 the cover 6 can be seated such that the grating 10 is disposed at the open side of the frame 1 to allow for the ingress of water to the drain located below the frame. Alternatively, as shown in Figure 2, the cover 6 can be seated such that the blind wall 9 is disposed at the open or forward side of the frame 1 thereby preventing the ingress of dirt, dust or sand.

Figure 3 illustrates the manner of location of the pins 11 of the cover 6 within slots 12 and 13 of the frame 1. With the pins disposed to the rear of the slots, the wall 9 or 10 (as the case may be) of the cover 6 rests within recess 14 of the spacing bar 5 of the frame 1, whilst the wall 10 or 9 respectively locates within the rear of the frame between bearing surfaces 1 5. From this position the cover 6 cannot be removed from the frame 1 by a direct upward or forward pull, but must be moved slightly upward to remove wall 9 or 10 (as the case may be) from recess 14 and then forward until the pins 11 are aligned with upward directed portions 17 and 1 8 of the slots 12 and 1 3. The cover 6 may then be lifted free.

It is observed that once the appropriate forward pins 11 are free of the slots 12, the rear pins 11 may be moved to a forward position 19 in the slots 1 3 whereupon the cover 6 may be tilted about the rear pins 11 to the position shown in chain dotted lines 20. Key holes 21 (Figures 1 and 2) are provided for appropriate keys to enable the movement and removal of the cover 6 herein described.

Claims

1. A gully assembly comprising a frame having generally upright side walls, at least one water inlet opening being provided in the side walls, and a cover arranged for seating upon the frame in two alternative positions in the first of which it exposes the water inlet opening in the frame and in the second of which it closes the water inlet opening in the frame.

2. A gully assembly as claimed in Claim 1 wherein the frame is generally rectangular in plan view.
