Description

COMBINATION RODDING POINT AND DRAI .
Access must be provided to waste water and surface water pipes to permit cleaning and inspection of the piping. present, the access eyes for this purpose are mounted as an integral component in the pipeline, and the eye is covered wit a screw cap or a lid with visible locking screws. Since acce eyes are most often located beneath the floor, a separate cov at floor level, for example a cover plate, is also required. If the access eye is mounted in a wall, it must be covered wi a separate inspection flap.
At present, the rodding point is mounted as an independent component at floor level with a branch line leadi to the pipeline. The rodding point has a lid with visible locking screws and does not ordinarily need to be covered wit a separate cover plate.
Neither present-day access eyes rior rodding points can be converted into a drain with a water trap.
The rodding point of the invention requires- no independent cover plate, does not have a screw cap or lid with locking screws, and if desired can be utilized as a drain having a water trap.
The rodding point of the invention is distinctive in that the seal is obtained with an inspection cap which is so formed that' it constitutes one-half of a water trap. The inspection cap is retained in position by a locking cup which is so formed that it constitutes the other half of the water trap. The rodding point can thus be converted into a drain by removing a plug in the inspection cap. The rodding point and the drain can be covered by a grating or a cover plate adapted to the requirements of the installation.
The rodding point and drain can be mounted directly in the original socket, bend or tee of the pipe, and the seal between the pipe and a main component of the device is obtained by the pipe's original O-ring. The seal between the main component and the inspection cap is obtained by means of a rolling O-ring. The inspection cap is retained in place by means of a locking cup which is twisted into two locking grooves, and the device is covered with a cover plate, a cover, plate with a peripheral slot, or an open grating, as needed.
As a result, the rodding point requires no independe ' cover such as a separate cover plate or inspection flap. The invention has no screw cap or cover with locking screws. The invention can be used as a drain with a water trap and be covered with any desired cover plate or grating according to need.

Figure 12 shows a drain with an open grating as seen from above.
Figure 13 shows an open grating as seen from above. Figure 14 shows the open grating in cross section. 5 Figure 15 shows the clamping ring as seen from above. Figure 16 shows the clamping ring in cross section. A main component 1 has a pipe fitting/tapered end 1b which is adapted to the desired pipe dimensions in the was s ^ water/surface water pipes, for example 90 - 110 - 125 mm according to Norwegian Standard 3062. The tapered ends 1b will be inserted entirely within the socket, bend or tee of th pipe so that the square top part 1c will be visible after assembly.
The seal between the pipe and the tapered end 1b is obtained by utilizing the standard O-ring* in the pipe. The top part 1c has ribs 1d at the bottom thereof. In addition to stiffening the construction, the ribs 1d also serve the following functions:
Recesses provided on the lower part of two diametricall . opposed ribs form two grooves 1a for mounting a locking cup 3.
The ribs provide clearance between the locking cup 3 and the cover or grating.
The ribs provide drainage for water when a cover . plate having a -peripheral slot is utilized. The ribs provide clearance for a drain pipe which is passed through a bore in a grating 6 so that waste water does not spurt up through the grating
6 but runs freely down into a trap 8. The corners of the top part 1c are sharp on the outside edge and rounded off on the inside edge, that is region 1e between the inside and outside edges is bevelled off. A sharp instrument can then be inserted in one recess 1e for dislodging a cover 4.
The tapered end 1b has an internal recess 1f to provide space for a rolling O-ring 2a and a retaining ledge for an inspection cap 2. Four of the ribs 1d have a screw eye 1g, so that it is possible, if desired to fasten down the cover 4, cover plate with peripheral slot 5, or an open grating 6 and a clamping ring 7 with screws. The rolling O-rin 2a ensures a seal between the main component 1 and the inspection cap 2. When the device is used as an access port, the inspection cap 2 constitutes the sealing member which can be opened or closed as needed. The inspection cap 2 forms one-half of the trap 8 when the rodding point is converted into a drain. ^ REA
OMPI To convert the rodding point into a drain, a plug 2b is removed by cutting it out via a groove 2c. The plug 2b is mounted on an elevated portion of the inspection cap, which is also the portion that is gripped by a tool for opening and 5 closing the rodding point.
The locking cup 3 is secured to the main component 1 by means of 'two wedges 3a which fit within the grooves 1a.' The locking cup 3 holds the inspection cap in place, preventin . it from becoming dislodged, from the main component 1 in the 0 event of elevated pressure in the pipeline." The locking cup forms.the second half of the trap 8 when the rodding point is converted into a drain.
The cover 4 is a covering for the rodding point and is reversible. One side 4a is used when the cover is to be 5 covered with ceramic tiles and the other side 4b when the cover is to be installed flush with the floor, optionally covered with vinyl. The cover 4 has reinforcing ribs 4c. The cover plate with a peripheral slot 5 has the same appearance as the cover 4 but has smaller dimensions so that a peripheral 0 slot.--6b is formed for water drainage. One side 5c is utilized when the cover is to be overlaid with ceramic tiles, and the other side 5d when the cover plate is to be flush with the floor or optionally covered by vinyl. The cover plate 5. with , the peripheral slot has four knobs 5e for centering it on the 5 top part 1c. The plate has reinforcing ribs 5f.
The open grating 6 has square apertures 6a to allow water to pass through the grating. The apertures 6a are 10 x 10 mm square and have a wall thickness of 2 mm. By cutting" out some of the intermediate wall members of the gratin 0 a hole measuring 34 x 34 mm can be made, which is adapted to a drain pipe measuring 32 mm o.d.
The open grating 6 rests on the clamping ring 7. The clamping ring 7 clamps a vinyl floor covering in place between the top part 1c and the clamping ring 7. A slot 7b between the clamping ring and the top part is adapted to a 2-mm-thick vinyl floor covering for mounting the device in a bathroom floor. The clamping ring 7 will lie against the ribs 1d after assembly. The clamping ring 7 has a reinforc:
