Abstract

A covering hood for jointly covering a plurality of a load cell housings in which a load introduction pin protrudes from each load cell housing through a housing opening. The covering hood including a separate passage opening in an upper part of the covering hood for each load introduction pin. The covering hood can be connected to the individual load cell housings at each separate passage opening.

First claim

1 - 9 . (canceled)

10 . A covering hood for covering a plurality of load cell housings, each respective load cell housing having a respective housing opening with a respective load introduction pin protruding there through, the covering hood including:
(a) a covering hood upper part having a separate passage opening formed therein for each load introduction pin; (b) a respective fastening means for each separate passage opening formed in the covering hood upper part; and (c) wherein the covering hood upper part and each respective fastening means are configured so that when the covering hood upper part and each respective fastening means are in an operating condition with respect to the plurality of load cell housings, each respective load introduction pin protrudes through a different one of the separate passage openings of the covering hood upper part and at each separate passage opening a respective fastening means fastens the covering hood upper part to a respective one of the load cell housings.

11 . The covering hood of claim 10 wherein when the covering hood upper part and each respective fastening means are in the operating condition the covering hood upper part resides in sealing position against an upper side of the respective load cell housing around the periphery of each separate passage opening.

12 . The covering hood of claim 10 wherein each fastening means includes an internal threaded connector adapted to cooperate with an external threaded element associated with a respective load cell housing.

13 . The covering hood of claim 12 wherein each fastening means includes a labyrinth seal ring with an O-ring mounted at a lower surface of the labyrinth seal ring in position to face the covering hood upper part when the covering hood upper part and each fastening means are in the operating condition.

14 . An apparatus including:
(a) a plurality of load cell housings, each respective load cell housing having a respective housing opening with a respective load introduction pin protruding there through; (b) a covering hood having a covering hood upper part with a separate passage opening formed therein for each load introduction pin, the covering hood residing in an operating condition with respect to the plurality of load cell housings in which each respective load introduction pin protrudes through a different one of the separate passage openings of the covering hood upper part; and (c) a respective fastening means for each separate passage opening formed in the covering hood upper part, each respective fastening means fastening the covering hood to a respective one of the load cell housings at a different one of the separate passage openings.

15 . The apparatus of claim 14 wherein each respective housing opening and corresponding separate passage opening includes a respective sleeve protruding there through and through a respective one of the separate passage openings, and wherein each respective fastening means engages with a respective one of the sleeves to fasten the covering hood to a respective one of the load cell housings.

16 . The apparatus of claim 15 wherein each fastening means is a labyrinth seal ring having an internal thread adapted to be screwed onto an external thread of a respective one of the sleeves to engage an upper side of the covering hood upper part.

17 . The apparatus of claim 15 wherein each fastening means is a labyrinth seal ring formed integrally with a respective one of the sleeves.

18 . The apparatus of claim 15 wherein each sleeve includes an external threaded portion and each housing opening includes an internal thread adapted to threadingly receive a respective one of the sleeves.

19 . The apparatus of claim 15 further including securing means associated with each respective sleeve for secured the respective sleeve against unintended detachment from the respective load cell housing.

20 . The apparatus of claim 15 wherein each respective sleeve has an integrally formed or attached flange that cooperates with a respective one of the load cell housings to specify the position of the sleeve relative to the respective load cell housing.

21 . The apparatus of claim 14 wherein each fastening means includes a labyrinth seal ring with an O-ring mounted at a lower surface of the labyrinth seal ring facing the upper part of the covering hood.
