Coil support for a trimmer line coil

摘要

A coil support with a coil of a trimmer line has a coil core with an outer wall surface and first and second axial ends. At the axial ends securing elements that project past the wall surface of the coil core are provided for positional fixation of the coil wound onto the coil core. A securing element provided at the first axial end is a support plate with a longitudinal center axis. The size of the support plate is provided in the direction of the longitudinal center axis with a greater extension than transverse to the longitudinal center axis such that the support plate in a first radial direction of the coil core is greater than in a second radial direction. The coil core is fixedly connected with the support plate and with the further securing elements that are provided on the second axial end.

1. A coil support with a coil of a trimmer line for a trimmer, the coil support provided with a longitudinal coil support center axis and comprising:
a coil core having a core center axis and comprising an outer core wall surface, wherein the coil core is a hollow coil cylinder and comprises a rotational drive follower; the coil of the trimmer line wound onto the outer core wall surface and having an inner end section of the trimmer line and an outer end section of the trimmer line, wherein the coil support is driven in rotation about the core center axis of the coil core via the rotational drive follower for winding the coil of the trimmer line onto the outer core wall surface; the coil core having a first axial end and a second axial end; a first securing element connected to the first axial end and second securing elements connected to the second axial end, wherein the first and second securing elements provide positional fixation of the coil of the trimmer line wound onto the outer core wall surface of the coil core, wherein the first and second securing elements project radially past the outer core wall surface of the coil core; wherein the first securing element is a support plate that defines a support plate plane, wherein the support plate plane is arranged in an x-y plane of a three dimensional coordinate system, wherein the y axis of the three dimensional coordinate system is defined by the longitudinal coil support center axis and wherein the z axis of the three dimensional coordinate system is defined by the core center axis of the coil core; wherein the support plate has an extension measured in a direction of the y axis and a width measured in a direction of the x axis of the three dimensional coordinate system, wherein the extension is greater than the width, and wherein the extension is comprised of a first portion measured above the x axis and a second portion measured below the x axis, wherein the first portion above the x axis is larger than the second portion; wherein the coil core is connected fixedly with the support plate and with the second securing elements; wherein the coil core, the support plate, and the second securing elements form a monolithic component of plastic material.
