Abstract
A strapping apparatus includes a frame. A first strap is connected to the frame. An axle is installed on the frame. A second strap is connected to the axle. A spool is positioned around the axle. The spool defines a slit through which the second strap is directed. Two ratchets are connected to the spool and rotationally installed on the axle. A coil spring includes a first end connected to the axle and a second end connected to the frame in order to rotate the spool. A first detent is movable on the frame between an operative position in engagement with the ratchets and an idle position away from the ratchets. A handle is pivotally installed on the axle. A second detent is movable on the handle between an operative position in engagement with the ratchets in order to rotate the spool and an idle position away from the ratchets.
Claims22
A strapping apparatus comprising:
- a frame including two lateral members;
- a first strap connected to the frame;
- an axle installed on the frame and supported by the lateral members of the frame;
- a second strap connected to the axle;
- a spool positioned around the axle, the spool defines a slit through which the second strap is directed;
- two ratchets connected to the spool and rotationally installed on the axle;
- a coil spring comprising a first end connected to the axle and a second end connected to the frame in order to rotate the spool;
- a first detent movably installed on the frame between an operative position in engagement with the ratchets and an idle position away from the ratchets;
- a handle pivotally installed on the axle, with the handle having two cams spaced from each other and extending from the handle;
- a second detent movably installed on the handle between an operative position in engagement with the ratchets in order to rotate the spool and an idle position away from the ratchets,
- wherein the second detent engages the two lateral members on exterior sides of the handle opposite to the ratchets;
- wherein each of the two lateral members of the frame comprises a disc on which the axle rests and the second detent slides,
- with the ratchets intermediate the discs,
- with each cam located between one of the ratchets and one of the discs of the two lateral members,
- with each disc comprising:
- a first arched edge, with the second detent slideable on the first arched edge;
- and
- a second arched edge adjacent to the first arched edge, with the second arched edge having a longer radius than the first arched edge in order to keep the second detent from the ratchets;
- wherein the second arched edge of the disc of each of the lateral members of the frame has a longer radius than the ratchets.
