FIG. 1 shows atelescoping structure 1 in accordance with an embodiment. Thetelescoping structure 1 includes a hollowouter section 10, and a first to fourth hollowinner sections inner section 20 is slidably mounted in the hollowouter section 10. The second hollowinner section 30 is slidably mounted in the first hollowinner section 20. The third hollowinner section 40 is slidably mounted in the second hollowinner section 30. The fourth hollowinner section 50 is slidably mounted in the third hollowinner section 40. The fourth hollowinner section 50 may be connected a device which is configured to be driven by the telescoping structure. The second to fourth hollowinner sections 30 to 50 have a structure substantially identical to the first hollowinner section 20. The following description is thus given based on the hollowouter section 10 and the first hollowinner section 20. - The hollow
outer section 10 is a hollow straight prism having two openings. Referring toFIG. 2 , the hollowouter section 10 is a tube in the shape of a regular hexagonal prism which has a first tosixth sidewalls sixth sidewalls 11 to 16 are connected together to form a regular hexagonal prism by a plurality offirst ribs 17. Each of thefirst ribs 17 spans and interconnects three of the first tosixth sidewalls 11 to 16. - The hollow
outer section 10 includes a firsttop blocking member 18, at its top opening, and a firstbottom blocking member 19, at its bottom opening. The firsttop blocking member 18 may prevent the first hollowinner section 20 from moving out of the top opening of the hollowouter section 10. In an embodiment, the firsttop blocking member 18 is a rectangular metal plate. A first edge of the firsttop blocking member 18 is mounted to the hollowouter section 10. A second edge of the firsttop blocking member 18 extends towards the central axis of the hollowouter section 10. The second edge is opposite to the first edge. - The first
bottom blocking member 19 may prevent the first hollowinner section 20 from disengaging from the hollowouter section 10 through the bottom opening. The firstbottom blocking member 19 includes afirst mounting portion 191 and a firstelastic portion 192. The firstelastic portion 192 may be made of plastic or other elastic material. Thefirst mounting portion 191 is mounted to the hollowouter section 10. The firstelastic portion 192 protrudes upward from a top surface of thefirst mounting portion 191. The firstelastic portion 192 may cushion the impact when the first hollowinner section 20 reaches the limit of travel allowed by the hollowouter section 10. - A pair of first sliding
rails 111 are arranged on the interior surface of thefirst sidewall 11 of the hollowouter section 10. Each of the pair of first slidingrails 111 extends along a direction parallel to the central axis of the hollowouter section 10. The pair of first slidingrails 111 are spaced. - The
third sidewall 13 of the hollowouter section 10 defines a first guidinggroove 132. Thefifth sidewall 15 of the hollowouter section 10 defines a second guidinggroove 152. Each of thefirst sidewall 11, thethird sidewall 13, and thefifth sidewall 15 is not adjacent to one another. The first guidinggroove 132 is formed by a pair of first spaced guidingbars 131. The second guidinggroove 152 is formed by a pair of second spaced guidingbars 151. The first guidinggroove 132 and the second guidinggroove 152 extend along a direction in parallel with the central axis of the hollowouter section 10. - The first hollow
inner section 20 is a hollow straight prism having two openings. Referring toFIGS. 3 and 4 , the first hollowinner section 20 is a tube in the shape of a regular hexagonal prism which has a seventh totwelfth sidewalls second ribs 27 holds the seventh totwelfth sidewalls 21 to 26 together to form the regular hexagonal prism. Each of thesecond ribs 27 spans and interconnects three of the seventh totwelfth sidewalls 21 to 26. - The inner structure of the first hollow
inner section 20 is similar to the inner structure of the hollowouter section 10. For example, the first hollowinner section 20 includes a secondtop blocking member 28 similar to the firsttop blocking member 18, a secondbottom blocking member 29 similar to the firstbottom blocking member 19, a second slidingrail 211 similar to the first slidingrail 111, a third guidinggroove 232 similar to the first guidinggroove 132, and a fourth guidinggroove 252 similar to the second guidinggroove 152. The secondbottom blocking member 29 includes asecond mounting portion 291 similar to thefirst mounting portion 191 and a secondelastic portion 292 similar to the firstelastic portion 192. Thethird guiding groove 232 is formed by a pair of third spaced guiding bars 231. Thefourth guiding groove 252 is formed by a pair of fourth spaced guiding bars 251. Thethird guiding groove 232 and thefourth guiding groove 252 extend along a direction in parallel with the central axis of the hollowouter section 10. - A pair of first raised sliding
grooves 212 are arranged on the exterior surface of theseventh sidewall 21. The pair of first raised slidinggrooves 212 are spaced and extend along a direction in parallel with the central axis of the first hollowinner section 20. - A
first cam follower 233 is arranged on the exterior surface of theninth sidewall 23. Thefirst cam follower 233 includes fourrotating wheels 234. Asecond cam follower 253 is arranged on the exterior surface of theeleventh sidewall 25. Thesecond cam follower 253 includes fourrotating wheels 254. - The second to fourth hollow
inner sections 30 to 50 have a structure similar to that of the first hollowinner section 20. - Referring to
FIGS. 5 and 6 , in assembly, the top end of the first hollowinner section 20 is inserted into the hollowouter section 10. The pair of slidingrails 111 of the hollowouter section 10 engages in the pair of raised slidinggrooves 212 of the first hollowinner section 20. Thefirst cam follower 233, of the first hollowinner section 20, is received in thefirst guiding groove 132, of the hollowouter section 10, so that the fourrotating wheels 234 make contact with the interior surfaces, of the pair of first guiding bars 131. Thesecond cam follower 253 of the first hollowinner section 20 is received in thesecond guiding groove 152, of the hollowouter section 10, so that the fourrotating wheels 254 contact the pair of second guiding bars 151. Thus, a sliding movement of the first hollowinner section 20 relative to the hollowouter section 10 is facilitated. The first hollowinner section 20 is movable between a fully retracted position, in which the first hollowinner section 20 is substantially inserted in the hollowouter section 10, and an extended position, in which the first hollowinner section 20 projects outwards from the hollowouter section 10. Similarly, the second hollowinner section 30 can be slidably mounted in the first hollowinner section 20, the third hollowinner section 40 can be slidably mounted in the second hollowinner section 30, and the fourth hollowinner section 50 can be slidably mounted in the third hollowinner section 40. In use, thetelescoping structure 1 is operable by selectively extending and retracting the first to fourth hollowinner sections 20 to 40. - It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
