Breaker hammer for breaking hard objects

Abstract

A breaker hammer for breaking hard objects includes one or multiple striking faces. One striking face has a breaking portion inside. The breaking portion occupies about 80% of the area of the striking face. The breaking portion has a plurality of striking areas protruding from the striking face, thereby effectively striking and breaking hard objects.

Claims

1. A breaker hammer for breaking objects, comprising a striking face comprising a breaking portion inside, said breaking portion comprising at least three striking areas protruding from the striking face; wherein said breaking portion is a concentric circle area retracted a predetermined distance from a ring edge of the striking face; wherein each of said at least three striking areas comprises a top, and an extension spirally and outwardly extending from said top; wherein the tops of said at least three striking areas are located adjacent to a center of the striking face; and the tops protrude a greater distance from the striking face than a distance which the extensions protrude from the striking face; wherein said at least three striking areas are equidistantly symmetrically located adjacent to the center of the striking face; wherein a gap is formed between each adjacent two of said at least three striking areas; wherein said at least three striking areas are spirally arranged on said breaking portion; and wherein each of the extensions comprises a first side at one of the gaps and a second side at another one of the gaps in a way that a height of the first sides is higher than a height of the second sides.

DETAILED DESCRIPTION OF THE INVENTION

(5) The technical contents and features of the present invention will now be described hereinafter with reference to the accompanying drawings. Those skilled in the art can understand that the description terms of the preferred embodiment belong to a higher-level description that does not limit the application field of solar power generation modules, for example, hammer head structure or related technical terms include, but are not limited to, the manner specified in the description, the term location includes but is not limited to setting, approaching, connecting, or adjoining, and the number “a” of each component includes one and more than one component number. The directional adjectives such as “up”, “down”, “inside”, “outside”, “top”, and “bottom” mentioned in the contents of this specification are merely illustrative description terms based on the normal use direction, not as the purpose of limiting the scope of the claims.

(6) As shown in FIG. 1 to FIG. 4, a breaker hammer for breaking hard objects provided by the preferred embodiment of the present invention is specifically an American sledgehammer as an example. The breaker hammer has a first striking face 10 and a second striking face 20. The first striking face 10 and the second striking face 20 are respectively disposed at two opposite sides of the head of the breaker hammer. The first striking face 10 of the present preferred embodiment is generally an arc surface, which is mainly used for striking general objects. A handle 50 is provided between the first striking face 10 and the second striking face 20 of the breaker hammer.

(7) In the preferred embodiment, the second striking face 20 of the striker hammer is taken as an example with a substantially circular ring edge 22, and the ring edge 22 may also have other shapes such as a polygon or a special shape, so that the second striking face 20 can adjust the shape according to the actual application status. The second striking face 20 has a breaking portion 24 inside. The breaking portion 24 in the present preferred embodiment is mainly based on a concentric circle region with a predetermined distance retracted from the ring edge 22 toward the inside of the second striking face 20 as an example. The breaking portion 24 occupies approximately 80% of the area of the second striking face 20. Preferably, the breaking portion 24 may also occupy approximately 60-70% of the area of the second striking face 20, and the use and impact effects can be more concentrated and efficient.

(8) The breaking portion 24 of the second striking face 20 has at least two striking areas 26, each striking area 26 protruding from the second striking face 20. Specifically, in the preferred embodiment, four stroking areas 26 are arranged on the breaking portion 24 at an equal distance and symmetrically as an example. Each striking area 26 has a top 30 and an extension 32 spirally extending from the top 30. The arrangement of the striking areas 26 in the present preferred embodiment is based on the tops 30 of the striking areas 26 being equidistantly symmetrically located near the center of the second striking face 20. The extension 32 of each striking area 26 extends from the associating top 30 to the ring edge 22 of the second striking face 20. A gap 34 is formed between the extensions 32 of two adjacent striking areas 26, and the overall striking areas 26 form a spiral and rotating structure at the breaking portion 24.

(9) With the above-mentioned constituent members, when the second striking face 20 of the breaker hammer is used to strike hard objects such as stone objects, because of the design that each striking area 26 of the breaking portion 24 projects the second striking face 20, the striking areas 26 can contact the hard objects first. Using the top 30 of each striking area 26 to directly impact the surface of hard objects, the hard objects can be easily broken into pieces by the striking areas 26. Furthermore, each striking area 26 is centered on the center of the second striking face 20, which increases the instantaneous destructiveness when struck. The extensions 32 of striking areas 26 can increase the structural strength of striking areas 26 and further increase the destructive force. It can also use the spiral structure of the extensions 32 and each gap 34 to guide the debris generated after the destruction of hard objects to further increase the knock and damage effects of hard objects.
