Abstract
Presented here is a pole clamp that can be operated by a single hand, and which can clamp onto objects of various sizes and shapes. The clamp can be operated using a handle which, when pushed in an opening direction opposite a base member, opens the jaws on the clamp. The motion of the handle can adjust the opening of the jaws. In addition, the opening of the jaws can be adjusted using a thumb dial which can shorten and lengthen a locking member, which in turn adjusts the opening of the jaws. The clamp can lock onto the object when the handle is pushed in a direction opposite the opening direction, past the dead center point, and the locking member prevents further movement of the handle.
Claims21
An apparatus comprising:
- a base member comprising a base jaw, a medial portion and a base handle, the base jaw defining a base concave recess with base transverse ridges, the medial portion having a medial aperture defining a medial pivot, the base handle having a rear aperture defining a rear pivot, the base handle bisected by a notch coaxial with the rear pivot;
- an attachment mechanism defined by a surface opposite the base concave recess and partially extending through the base jaw, the attachment mechanism comprising a plurality of attachment members, each attachment member to engage with a corresponding attachment member and to partially support a weight of an object associated with the corresponding attachment member;
- an upper member comprising an upper jaw and a rear portion, the upper jaw defining an upper concave recess with upper transverse ridges opposite the base concave recess, the rear portion having a first upper aperture pivotally secured in a coaxial arrangement to the medial pivot of the base member and having a second upper aperture defining a second upper pivot;
- a handle defining a first handle aperture pivotally secured in a coaxial arrangement to the second upper pivot of the upper member, the handle having a second handle aperture defining a handle pivot;
- and
- a locking member having a proximal end and a distal end, the proximal end mounted within the notch of the base member and pivotally secured to the rear pivot of the base member, the distal end pivotally secured to the handle pivot, the locking member to lock a position of the upper jaw with respect to the base jaw when the handle pivot creates an angle greater than 180° with respect to the second upper pivot and the rear pivot of the base member.

An apparatus comprising:
- a base member comprising a base jaw, a medial portion and a base handle, the base jaw defining a base concave recess, the medial portion having a medial aperture defining a medial pivot, and the base handle having a rear aperture defining a rear pivot;
- an attachment mechanism defined by a surface opposite the base concave recess and partially extending through the base jaw, the attachment mechanism comprising a plurality of attachment members, each attachment member to engage with a corresponding attachment member and to partially support a weight of an object associated with the corresponding attachment member;
- an upper member comprising an upper jaw and a rear portion, the upper jaw defining an upper concave recess, the rear portion having a first upper aperture pivotally secured in a coaxial arrangement to the medial pivot of the base member and having a second upper aperture defining a second upper pivot;
- a handle defining a first handle aperture pivotally secured in a coaxial arrangement to the second upper pivot of the upper member, the handle having a second handle aperture defining a handle pivot;
- and
- a locking member having a proximal end and a distal end, the proximal end pivotally secured to the rear pivot of the base member, the distal end pivotally secured to the handle pivot, the locking member to lock a position of the upper jaw with respect to the base jaw.
3 more elements
A method comprising:
- adjusting a size of an opening defined by a base jaw associated with a base member and an upper jaw associated with an upper member opposite the base jaw, by rotating a handle around a second upper pivot in a first direction, the second upper pivot securing the handle to the upper member, said rotating the handle causing a rotation of the upper member around a medial pivot securing the upper member to the base member;
- clamping an object between the base jaw and the upper jaw by rotating the handle in a second direction opposite the first direction;
- locking, by a locking member, the base jaw and the upper jaw to the object by rotating the handle in the second direction, wherein the locking member is secured to a handle pivot of the handle and to a rear pivot of the base member, a length of the locking member determining a distance between the handle pivot and the rear pivot and preventing a variation in the distance, the locking member causing said locking when an angle at the handle pivot with respect to the second upper pivot and the rear pivot exceeds 180°;
- and
- attaching a second object using an attachment mechanism defined by a surface opposite a base concave recess and partially extending through the base jaw, the attachment mechanism comprising a plurality of attachment members, each attachment member to engage with a corresponding attachment member and to partially support a weight of the second object associated with the corresponding attachment member.
