Abstract:
1. A striking device comprising a head portion for striking an object or surface and an elongate handgrip connected to said head portion, said handgrip including: an elongate exterior shell having a central longitudinal axis, having a plurality of evenly distributed air holes for ventilation purposes and to firmly secure the user's grip thereof, and defining an elongate ventilation chamber, said air holes extending between said ventilation chamber and an exterior surface of said shell; and an air scoop section connected to a head end of said shell and forming two air inlets on opposite sides of said handgrip and on opposite sides of a central longitudinal plane, each air inlet opening into a respective air passage connected to said ventilation chamber at the head thereof, said air scoop section including a partition separating the two air inlets and the air passages and terminating at a thin partition edge at said ventilation chamber, said partition having airflow directing surfaces on opposite sides thereof which are gently concavely curved as seen in longitudinal cross-section and which, during use of and movement of said striking device, can direct outside air in a longitudinal direction of said handgrip into said ventilation chamber, each airflow directing surface having a substantially planar central section which slopes at an acute angle to said central longitudinal plane when said central section is viewed in transverse cross-section of the air scoop section, wherein the two air passages are connected by the ventilation chamber in such a manner that, when outside air enters one of said air inlets during use of the striking device, air is concurrently sucked out of the other air inlet helping to cool the handgrip.
