Patent DE-3124529-A1 (DE)
Title: Foot-wiping entrance mat
Inventor: KAMPMANN HEINRICH
IPC: A47L23/24
Filed: 1981-06-23
Abstract: In foot-wiping entrance mats for buildings, in particular for buildings with greatly frequented entrances, designs with insertion rails which are located adjacently and are releasably connected to one another in the transverse direction have proved to be expedient, the insertion rails having a receiving profile for exchangeable insertion strips. Due to their construction height and for their fastening, however, conventional mats of this type require a trough-shaped cutout in the floor with a mat frame and thus constructionally complex requirements which are often not present and are also difficult to change. A more easily mountable mat which is also simple to produce is provided by the fact that the insertion rails define, with their underside, a floor support surface of the mat and are connected at the sides via a positive-locking profile engagement in each case to a continuous intermediate rail arranged for linking between the insertion rails. A flat mat can thus be achieved, which is expediently further supplemented at the edges by sloping rails which provide a ramp-like transition to the floor level and avoid tripping edges.
Patent DE-3127763-A1 (DE)
Title: Unit for determining inflow quantities of bath water or similar liquids
Inventor: STANETZKI LOTHAR ING GRAD
IPC: E03C1/04
Filed: 1981-07-14
Abstract: According to the innovation, the unit for determining the inflow quantities of bath water or similar liquids can be used in both a horizontal and a vertical arrangement, without any modification to the commercially available fittings, for bathtub/shower installations with two taps for cold-water inflow and hot-water inflow in each case, for mixer units with only one tap and a cold-water/hot-water mixer lever, and also for the most recent embodiment with only a single lever for simultaneous water inflow and cold/hot adjustment. It is to be emphasised that, in the case of two taps for cold-water inflow and hot-water inflow in each case, independently of the adjustment thereof for the desired inflow quantity and water temperature, automatic turning-off of the taps and thus shutting-off of the water inflow when the desired level of water or similar liquid has been obtained is carried out individually and fundamentally mechanically in the case of all embodiments by simulating the action otherwise carried out manually, such as turning off the taps or pushing down the lever in the case of single-lever bathtub/shower installations.
