Abstract:
1. A strap winder, comprising: a base having a first strap end connecting structure; a ratchet wheel rotatably mounted in the base and having a second strap end connecting structure, wherein the ratchet wheel has a locking structure at one end and a flange at the other end; and a handle pivotably mounted to the base, wherein the base has two ratchet wheel mounting openings and the handle has two ratchet wheel passing openings, wherein the ratchet wheel mounting opening and ratchet wheel passing opening on a flange side of the ratchet wheel are larger than the ratchet wheel mounting opening and ratchet wheel passing opening on the locking structure side of the ratchet wheel, wherein the handle has an advancing ratchet with an arm extending from the handle to the ratchet wheel along a direction which is tangent to the ratchet wheel engaging the ratchet member so that pivot of the handle in an opening movement, wherein the handle is moved away from the base, does not rotate the ratchet wheel, and wherein pivot of the handle in a closing movement, wherein the handle is moved toward the base, rotates the ratchet wheel which extends through the ratchet wheel mounting openings and the ratchet wheel passing openings, wherein the locking structure snaps through one of the ratchet wheel mounting openings to hold the ratchet wheel in place relative to the base and the handle.
