Compactor for compacting soil
First Claim
Patent Images
1. A manually guided tamping appliance for ground compaction comprising:
- a tamping implement having a working mass, a crank mechanism that is spaced from the working mass, and a spring assembly that is arranged between the crank mechanism and the working mass and that couples the working mass to the crank mechanism;
an internal combustion engine which drives the working mass linearly back and forth via the crank mechanism; and
an at least single-axle traveling gear that additionally supports the tamping implement against the ground, wherein the entire tamping element is dynamically movable as a unit relative to the traveling gear.

Abstract
A compactor for compacting soil which can be controlled by hand using a bow-shaped control element or similar element. The compactor has a compacting or ramming working mass which is driven by a combustion engine back and forth, linearly, by a crank mechanism and a spring assembly. The compactor is also supported on the ground by a single-axle dolly.

13. A manually guided tamping appliance for ground compaction comprising:
-
a tamping implement having a working mass, a crank mechanism, and a spring assembly arranged between the crank mechanism and the working mass;
an internal combustion engine which drives the working mass linearly back and forth via the crank mechanism; and
an at least single-axle traveling gear that additionally supports the tamping implement against the ground, wherein the tamping implement is movable relative to the traveling gear; and
a countermass capable of being driven by the engine in the opposite direction to the movement of the working mass over a large part of the range of movement of the working mass.- View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A manually guided tamping appliance for ground compaction comprising:
-
a tamping implement having a working mass and a crank mechanism that drives the working mass to reciprocate linearly;
an at least single-axle traveling gear that additionally supports the tamping implement against the ground;
an internal combustion engine that supplies drive power to the working mass;
a coupling that articulates the traveling gear to the tamping implement, the coupling being sufficiently flexible to permit limited dynamic movement of the tamping implement relative to the traveling gear; and
a countermass that is driven by the engine in the opposite direction to the direction of movement of the working mass over a large part of the range of movement of the working mass.

26. A manually guided tamping appliance for ground compaction comprising:
-
a tamping implement having a working mass and a crank mechanism that drives the working mass to reciprocate linearly;
an at least single-axle traveling gear that additionally supports the tamping implement against the ground;
an internal combustion engine that supplies drive power to the working mass; and
an elastic coupling that articulates the traveling gear to the tamping implement, the coupling being sufficiently flexible to permit limited dynamic movement of the entire tamping implement as a unit. - View Dependent Claims (27)
