Telescopic assembly

A telescopic assembly comprising

• an inner tube substantially closed at one end and open at the other end,
• an outer tube substantially closed at one end and open at the other end, said outer tube being movably disposed onto said inner tube,
• a motive power source having a rotatable hollow output shaft, said motive power source being disposed within said inner tube and affixed to the closed end thereof to prevent rotation therebetween,
• a screwed spindle affixed to said rotatable output shaft at one end, and
• a driving tube screwed onto said spindle at one end and affixed to said closed end of the outer tube, whereby rotation of said motor output shaft and said screwed spindle effects reciprocal displacement of said inner tube, said driving tube extends substantially into said hollow output shaft when retracted so that the minimum height of the assembly as well as the length of stroke correspond substantially to the length of said motive power source.
