Abstract
A gear wrench allowing easy force application, having: a head, formed with a receiving compartment thereon for receiving a gear ring, the head extending along a first plane; a tail, extending along a second plane; and a neck, provided between and integrally formed with the head and the tail; characterized in that: the first plane is parallel to the second plane, and the neck obliquely extends from the head towards the tail to form a height difference between thee head and the tail. As such, the vertical component of force may be eliminated or minimized so as to effectively reduce occupational hazards; the horizontal component of force may also be increased such that the operator only requires a lower force to effectively tighten or loosen up a fastener.
Claims13
In a gear wrench allowing easy force application, the improvements comprising:
- a head (20) with a receiving compartment thereon for receiving a gear ring, the head extending along a first plane;
- a tail (30) extending along a second plane;
- a neck (50) between and integrally joining the head and the tail;
- and
- a box end (42) at an end of the neck opposing the head (20), whereby the box end and tail allow a hand of a user to easily hold and exert a force on the gear wrench with minimized or eliminated vertical component;
- characterized in that the first plane is parallel to the second plane, the neck obliquely extends from the head towards the tail to form a height difference between the head and the tail, the neck is formed with smooth curves where the neck joins to the head and the tail, and a portion of a grip shares one of the first and second planes.
A gear wrench allowing easy force application, comprising:
- a head (20), formed with a receiving compartment thereon for receiving a gear ring, the head extending along a first plane;
- a tail (30) extending along a second plane;
- a second box end (42) at an end of the gear wrench opposing said head (20);
- and
- a neck (50), provided between and integrally formed with the head and the tail;
- characterized in that:
- the first plane is parallel to the second plane, and the neck obliquely extends from the head towards the tail to form a height difference between the head and the tail;
- the neck is formed with smooth curves at where the neck joins to the head and the tail;
- and the neck includes a part extending along a third plane parallel to the second plane;
- and in that said second box end and said tail allow a hand of a user to easily hold and exert a force on said gear wrench without vertical component of said force or with minimized vertical component of said force.
