Abstract
A G-hook for the mutual releasable connection of two prop portions of a telescopic construction prop has a pin and a hoop. The pin and the hoop are different, separate parts which are rotationally rigidly connected to one another, meaning the pin cannot rotate relative to the hoop because they are rigidly fixed to one another. The pin has a force introduction portion with a surface which is curved regionally and a force removal portion which is diametrically opposite the force introduction portion and whose surface is formed substantially planar.
Claims25
A G-hook for the mutual releasable connection of two prop portions of a telescopic construction prop, the G-hook comprising:
- a pin configured for the mutual connection of the two prop portions;
- and
- a hoop configured for captively securing the pin to the telescoping construction prop;
- wherein the pin and the hoop are two different parts which are produced from different qualities of steel, wherein the pin is of a higher quality of steel in comparison to the hoop, the pin configured to be dimensioned and manufactured for increased bending load capability, transverse force bearing capability, and bearing stress in comparison to the hoop and wherein the pin and hoop are rotationally rigidly connected to one another;
- wherein the pin comprises a force introduction portion diametrically opposed to a force removal portion, where the force introduction portion comprises a first surface which is curved at least regionally, and where the force removal portion comprises a second surface that is substantially planar, or where the second surface has a curvature which is less curved than the curvature of the first surface.
A G-hook for the mutual releasable connection of two prop portions of a telescopic construction prop, the G-hook comprising:
- a pin configured for the mutual connection of the two prop portions, the pin comprising a freely projecting first end disposed opposite a second end of the pin, where the second end of the pin comprises a blow surface that is substantially perpendicular to a longitudinal length of the pin;
- and
- a hoop comprising a curved free end opposite a second end, where the second end of the hoop is non-moveably connected to the second end of the pin, and wherein the curved free end of the hoop is configured for captively securing the pin to the telescoping construction prop;
- wherein the pin and the hoop are separately manufactured parts of two different qualities of steel, wherein the pin is of a higher quality of steel in comparison to the hoop, the pin configured to be dimensioned and manufactured for increased bending load capability, transverse force bearing capability, and bearing stress in comparison to the hoop.
A G-hook for the mutual releasable connection of two prop portions of a telescopic construction prop, the G-hook comprising:
- a pin portion connected to a hoop portion, where the pin portion is separately manufactured from the hoop portion but non-movably connected to one another;
- where the pin portion is configured for the mutual connection of the two prop portions, and where the pin portion comprises a freely projecting first end disposed opposite a second end along a longitudinal length, where the second end comprises a blow surface that is substantially perpendicular to the longitudinal length of the pin portion, and wherein the pin portion comprises a force introduction portion diametrically opposed to a force removal portion both disposed along its longitudinal length, where the force removal portion is substantially planar and the force introduction portion is substantially curved;
- and
- wherein the hoop portion comprises a curved free end opposite a second end, where the second end of the hoop portion is non-moveably connected to the second end of the pin portion, wherein the curved free end of the hoop portion is configured for captively securing the pin portion to the telescoping construction prop;
- wherein the pin portion and the hoop portion are produced from steels of different quality, wherein the pin portion is of a higher quality of steel in comparison to the hoop portion, the pin configured to be dimensioned and manufactured for increased bending load capability, transverse force bearing capability, and bearing stress in comparison to the hoop.
A G-hook for the mutual releasable connection of two prop portions of a telescopic construction prop, the G-hook comprising:
- a pin configured for the mutual connection of the two prop portions;
- and
- a hoop attached to the pin, the hoop configured for captively securing the pin to the telescoping construction prop;
- wherein the pin comprises a force introduction portion diametrically opposed to a force removal portion;
- wherein the force introduction portion comprises a first surface having a planar surface middle region disposed between two curved surface side regions;
- and
- wherein the force removal portion comprises a second surface that is substantially planar, or wherein the second surface has a curvature which is less curved than the curvature of the first surface.
