_e Title; Plastic-molded gas-ejector for continuous use; for picking up lost dog excrement ·

The above purpose is served by keeping the environment clean using a gripping device that is carried with one's hand.

A gripper was created and assembled that functions in a way that is both handy and aesthetic. It is a type of pliers deformation and is manufactured using a plastic injection molding process. Its individual parts, consisting of two bars and a special-purpose axis, are brought together and connected to a punctured axis that is simply inserted. The axis joint shows that the ends are covered with limiting surfaces, with which the two grip bars are connected and surrounded by a rubber ring to hold them together until they are clamped. These four individual parts form the complex device structure, with the bars on the one hand having practical auxiliary grip deformations, while on the other hand the ends of the bars are fitted with specially shaped holding clamps (haw. clamps ) , onto which cardboard gripping strips are placed, which then achieve the desired cleaning effect/dirt _{absorption via} the bars' opening and closing movements.

In order to make the device structure stable, the Gb ¹ I?. wood cross-sections were formed into a double T shape, resulting in an attractive, modern, pleasing appearance, including the chosen short form of the device, as the pocket format (plug-in) offers in a practical way. The outer surfaces are shiny and smooth, which is the opposite of what a "quick pitchfork" would require, especially since the grip itself can be carried out quickly and precisely without being noticed.

Further features of the contactor gripping device in terms of shape and structure are shown in the sketches/drawings.

Fig. 1 explains the Holmen 4OeSSeIi head section represents the actual handle,

Fig. 2 is the second gripping bar which can only be moved from the top with a thumb pressure, but has a grooved surface to ensure a good grip.

Fig» 5 shows the joint axis to be inserted, the lateral ends of which are equipped with limiting surfaces (stops),

Figo 4· are the ends of the spars and are deformed with clamps similar to clamps j whose retaining straps / plastic-elastic-

release tension, and on the other hand the holding surface is slightly serrated in order to hold the cardboard shell (they are stuck) firmly.

Fig. 5 shows only dotted lines of the shells to be attached ,

Fig. 6 shows the material cross-section, the double-T shape of which stabilizes the lightweight plastics, but at the same time gives the gripping unit its elegant appearance,

Fig. 7 is a rubber ring _tensioning band, firstly it holds the spars together and secondly it provides the gripping thrust, $. the two gripping shells lying next to each other are kept locked, which ensures the aesthetic value after dirt has been picked up and thus makes the complex object - in terms of shape, construction and creative design - suitable as a throwing tool worthy of design protection.
