## Abstract

A glider assembly for a handheld trimmer includes a glider shaft coupleable at one end with a rotating head of the handheld trimmer, and a glider plate connected to an opposite end of the glider shaft. The glider plate is part-spherical or saucer shaped and includes a concave side and a convex side. A bearing acts between the glider plate and the glider shaft. The assembly enables an operator to rest the weight of the trimmer on the ground during use while controlling a cutting height.

## Claims

### Claim 1

A glider assembly for a handheld trimmer including a rotating head that supports a cutting line, the glider assembly comprising:
a glider shaft coupleable at one end with the rotating head;
a glider plate connected to an opposite end of the glider shaft, the glider plate being part-spherical or saucer shaped and including a concave side and a convex side;
a convertible cap attachable directly to the rotating head and disposed between the glider shaft and the rotating head such that the glider shaft is coupleable with the rotating head through the convertible cap, wherein the convertible cap includes channels for supporting a molded cutting line; and
a bearing acting between the glider plate and the glider shaft, wherein the bearing is structured and cooperable with the glider plate such that the glider plate is free spinning and disconnected from influence by the rotating head at all times,
wherein the glider shaft comprises a threaded connector, and wherein the bearing comprises a bearing set including at least one of a first bearing secured to the glider plate and coupled with a distal end of the glider shaft and a second bearing secured to the convertible cap coupled with the glider shaft, the threaded connector extending through the first bearing in the glider plate and through the second bearing in the convertible cap, and
wherein the glider plate is spaced from the convertible cap by the glider shaft.

### Claim 2 (depends on 1)

A glider assembly according to claim 1, wherein the glider plate comprises a bearing channel, wherein the first bearing is secured in the bearing channel in the glider plate, and wherein the threaded connector is clamped through the first bearing.

### Claim 3 (depends on 1)

A glider assembly according to claim 1, wherein the glider plate is configured to support a weight of the handheld trimmer during operation of the handheld trimmer.

### Claim 4 (depends on 1)

A glider assembly according to claim 1, further comprising the molded cutting line secured in the channels of the convertible cap.

### Claim 5 (depends on 1)

A glider assembly according to claim 1, wherein the glider plate is part-spherical or saucer shaped across a full diameter of the glider plate.
