A telescopic support prop, comprising:
- a leg with a lower leg part and an upper leg part, the upper leg part having a plurality of vertically spaced through holes,
- a locking pin releasably connected to one of the vertically spaced through holes of the upper leg part in a locked position, wherein the locking pin is formed of a linearly locking portion for insertion into one of the plurality of vertically spaced through holes of the upper leg part and a curved retention portion which comes into abutment with an exterior of the lower leg part when the locking pin is moved from the locked position to an unlocked position, and
- a cap connected to the locking pin, the cap having a fastening sleeve put over an end of the locking pin, wherein the cap further comprises a spring for engagement by an exterior of the lower leg part.
A locking pin for securing an upper leg part against a lower leg part of a telescopic support prop, comprising:
- a pin for connection to a through hole of the telescopic support prop, wherein the pin has a linear locking portion for insertion into a through hole of the upper leg part and a curved retention portion which is formed as a U-bend, and
- a cap connected to the pin, the cap having a fastening sleeve put over an end of the pin, wherein the cap further comprises a spring for bearing against the leg.
A telescopic support prop, comprising:
- a leg with a lower leg part and an upper leg part, the upper leg part having a plurality of vertically spaced through holes, and
- a locking pin for securing the upper leg part against axial movement relative to the lower leg part, the locking pin having a pin with a first linear portion for insertion into one of the plurality of vertically spaced through holes of the upper leg part, the pin further having a curved retention portion with an inner diameter corresponding to an outer diameter of the lower leg part, the locking pin further having a spring, the spring being engaged by an exterior of the lower leg part when moving the locking pin from a locked position to an unlocked position.
