Abstract
A hand rivet squeezer with adjustable handles includes a riveting head body, and C-shaped anvil yoke and stationary and lever swing-arm handles attached to the body. A mechanical linkage inside the body converts pivoting forces applied to the lever swing-arm into axial forces applied to a plunger pushing it from inside the body into the C-shaped yoke. The preferred mechanical linkage is a rack-and-pinion type design or alternatively a cam between the lever swing arm and the plunger. The handles are adjustable such that their angle relative the rivet head body can be varied depending on the access available around a solid rivet to be installed. The handles are engaged or locked to the body but may be unlocked or slidably disengaged and pivoted up to 90 degrees relative the body.
Claims16
A rivet squeezer comprising:
- a riveting head body;
- a C-shaped yoke connected to the body and extending away from the body forming an anvil;
- a stationary handle releasably fixedly attached and pivotally attached to the body;
- a lever swing arm handle pivotally attached to the body;
- and,
- a mechanical linkage connected from the lever swing arm handle to a plunger to convert pivoting forces applied to the lever swing arm handle into axial forces applied to the plunger tending to push the plunger outside the body towards the anvil;
- and
- the stationary handle upon being released from fixed attachment to the body being pivotable relative the body thereby adjusting the stationary handle angle relative the body.
A rivet squeezer comprising:
- a riveting head body;
- an anvil extending away from the body;
- a stationary handle releasably fixedly attached and pivotally attached to the body;
- a lever swing arm handle pivotally attached to the body;
- and,
- a mechanical linkage connected to the lever swing arm handle to convert pivoting forces applied to the lever swing arm handle into axial forces applied to a plunger tending to push the plunger outside the body towards the anvil;
- and
- the stationary handle upon being released from fixed attachment to the body being pivotable relative the body thereby adjusting the stationary handle angle relative the body;
- wherein the mechanical linkage comprises:
- a first engagement gear connected to the lever swing arm handle and having one or more teeth;
- the plunger having one or more corresponding teeth and engaged with the first engagement gear;
- and wherein the engagement gears are fixedly connected together with the teeth offset from one another and the sets of teeth in the plunger are correspondingly offset.
A rivet squeezer comprising:
- a riveting head body;
- an anvil extending away from the body;
- a stationary handle releasably fixedly attached and pivotally attached to the body;
- a lever swing arm handle pivotally attached to the body;
- and,
- a mechanical linkage connected to the lever swing arm handle to convert pivoting forces applied to the lever swing arm handle into axial forces applied to a plunger tending to rush the plunger outside the body towards the anvil;
- and
- the stationary handle upon being released from fixed attachment to the body being pivotable relative the body thereby adjusting the stationary handle angle relative the body;
- wherein the mechanical linkage comprises a cam pivotally connected to the body and configured such that forces applied to the lever swing arm handle are transferred to the plunger.
