Description

Field of the invention

[0001] The invention relates to an asphalt pusher, comprising a handle device and a pusher blade and a coupling device for coupling the pusher blade to the handle device. Background of the invention

[0002] Asphalt scrapers are generally known that comprise a handle assembly and a blade connected to it. The asphalt scraper blades are arranged in such a way that they form a front surface essentially perpendicular to the longitudinal axis of the handle assembly, which, as such, represents the main working surface of the asphalt scraper. The blade can be made of solid material or a hollow profile. Solid materials offer high strength, while hollow profiles are characterized by their low weight. Object of the invention

[0003] The invention is based on the object of demonstrating solutions which make it possible to create an asphalt pusher which is characterized by a robust and cost-effective construction and by advantageous usage characteristics for the field of road construction and asphalt spreading. Inventive solution

[0004] This object is achieved according to the invention by an asphalt pusher, with: - a handle device, - a slide blade, and - a coupling device for coupling the slide blade with the handle device, - the slide blade is designed as a hollow profile, - the hollow profile has a slide wall on a side facing away from the handle device which provides a main working surface, - the main working surface is a narrow, elongated rectangular surface which is aligned perpendicular to a longitudinal axis of the handle device and is delimited by mutually parallel edge phases. - first and second roof walls rise from the edge phases towards each other and are connected to each other in a roof edge area. - the two roof walls, the two edge phases and the slide wall define a hollow profile interior and - the hollow profile interior is penetrated by at least one web which extends in the longitudinal direction of the slide wall and connects at least one of the roof walls or the roof edge area with the slide wall.

[0005] This makes it possible to advantageously create an asphalt pusher that is characterized by high strength and moderate weight.

[0006] The asphalt scraper according to the invention is preferably designed such that the cross-section of the hollow profile is symmetrical, so that the scraper blade, upon rotation by 180° around the longitudinal axis of the handle, returns to a use position in which, for example, a previously unaffected edge phase imparts a high level of quality to the scraper's removal action. The plane of symmetry is a longitudinal center plane perpendicular to the scraper wall and containing the longitudinal axis of the handle. The handle is formed by a rod structure.

[0007] The cross-section of the hollow profile is preferably designed to include a longitudinal web connecting the roof edge area with the longitudinal center area of ​​the slide wall. This longitudinal web preferably runs along a plane of symmetry of the hollow profile and is perpendicular to the inside of the slide wall.

[0008] The hollow profile can also advantageously be designed to include two longitudinal webs that connect the longitudinal center area of ​​the respective roof wall with the inside of the slider wall. These two webs can then also be combined with the aforementioned center web.

[0009] The coupling section is preferably formed by a pipe socket. This pipe socket is preferably made of the same material as the hollow profile and is welded to the hollow profile.

[0010] The distance between the longitudinal webs which are connected to the roof wall can advantageously be dimensioned such that it essentially corresponds to the diameter of the pipe section forming the coupling device.

[0011] The hollow profile is preferably an extruded aluminum profile. The aforementioned webs form an integral part of the hollow profile and are formed during the extrusion process. Short description of the characters

[0012] Further details and features of the invention will become apparent from the following description taken in conjunction with the drawing. It shows: Fig. 1 is a perspective view of an asphalt pusher according to the invention to illustrate the structure thereof; Fig. 2 a sketch illustrating a preferred cross-sectional design of the slide blade; Fig. 3 a sketch to illustrate a further advantageous cross-sectional design of the slide blade; Detailed description of the characters

[0013] The representation according to Fig. 1 shows an asphalt pusher, with: - a handle device 1, - a slide blade 2 , and - a coupling device 3 for coupling the slide blade 2 with the handle device 1, - wherein the slide blade 2 is designed as a hollow profile, - the hollow profile has a slide wall 2a on a side facing away from the handle device, which provides a main working surface WS, - the main working surface WS is a narrow, elongated rectangular surface which is aligned perpendicular to a longitudinal axis X of the handle device 1 and is delimited by mutually parallel edge phases 4, 5, - first and second roof walls 6, 7, which are arranged towards each other from the edge phases 4, 5, rise and are connected to each other in a roof edge area 8, - the two roof walls 6, 7, the two edge phases and the slide wall define a hollow profile interior and - the hollow profile interior is penetrated by at least one web S1, S2, S3 which extends in the longitudinal direction of the slide wall 2a and connects at least one of the roof walls 6, 7 or the roof edge region 8 to the slide wall 2a.

[0014] In the Fig. 2 and Fig. 3, the cross-section of the hollow profile is designed such that it comprises a longitudinal web S1 which connects the roof edge region 8 with the longitudinal center region of the slide wall 2a.

[0015] This longitudinal web S1 runs along a plane of symmetry of the hollow profile and is perpendicular to the inside of the sliding wall 2a.

[0016] In the variant according to Fig. 2, the hollow profile comprises two longitudinal webs S2, S3 which connect the longitudinal center area of ​​the respective roof wall 6, 7 with the inside of the slide wall 2a.

[0017] The coupling section 3 is formed by a pipe socket welded to the hollow profile via weld seams W. The spacing of the longitudinal webs S2, S3, which are connected to the roof walls 6, 7, essentially corresponds to the diameter of the pipe section 3 forming the coupling device. The hollow profile is an extruded aluminum profile.
