Mechanism for electrically adjusting work surface position
An adjustment mechanism assembly for adjusting a work surface position vertically includes a vertical guiding element, a work surface support element engaged with the vertical guiding element and configured to be movable vertically with electric actuation, and means for the electric actuation comprising a cable. The adjustment mechanism assembly includes a vertical support member which extends vertically from within the vertical guiding element to outside it or resides completely within the vertical guiding element. The cable includes a spiraled portion between its termini, which spiraled portion is supported with respect to its central axis by the support member. The disclosed solution also has a wall structure and a table comprising such an adjustment mechanism assembly.
1. An adjustment mechanism assembly for adjusting a work surface position vertically, comprising
a non-telescopic vertical guiding element consisting of one vertical guiding member,
a work surface support element engaged with the vertical guiding element and configured to be movable vertically with electric actuation, which work surface support element is arranged to protrude horizontally from within the vertical guiding element between the ends of the vertical guiding element,
means for said electric actuation comprising a cable, and
a non-telescopic vertical support member which resides at least partially within the vertical guiding element,
which cable comprises a spiraled portion between its termini, which spiraled portion is supported with respect to its central axis by the vertical support member.
2. The adjustment mechanism assembly according to claim 1 , wherein the vertical support member extends vertically from within the vertical guiding element to outside the vertical guiding element, or wherein the vertical support member resides completely within the vertical guiding element.
3. The adjustment mechanism assembly according to claim 1 , wherein
at least a portion of the spiraled portion of the cable resides outside the vertical guiding element.
4. The adjustment mechanism assembly according to claim 1 , wherein
the cable is arranged to enter into inside of the vertical guiding element at the work surface support element.
5. The adjustment mechanism assembly according to claim 1 , wherein
an end portion of the vertical support member which resides outside the vertical guiding element is connected to a support element configured to prevent movement of said end portion of the vertical support member.
6. The adjustment mechanism assembly according claim 1 , comprising
at least two strain relievers connected to the cable such that the spiraled portion of the cable resides between two strain relievers.
7. The adjustment mechanism assembly according to claim 6 , wherein
a support element comprises one of said two strain relievers,
the work surface support element comprises another of said two strain relievers, and
the spiraled portion of the cable resides between these two strain relievers.
8. The adjustment mechanism assembly according to claim 1 , wherein
the vertical support member is a rod and
the spiraled portion of the cable is spiraled around the rod.
9. The adjustment mechanism assembly according to claim 1 , wherein
the vertical support member is a pipe comprising a vertically extending slit, and
the spiraled portion of the cable is housed within the pipe.
10. The adjustment mechanism assembly according to claim 1 , wherein
the vertical support member is an enclosure comprising a vertically extending slit, and
the spiraled portion of the cable is housed within the enclosure.
11. The adjustment mechanism assembly according to claim 1 , wherein
the vertical support member is a plate or wall, and
the spiraled portion of the cable resides next to the plate or wall.
12. The adjustment mechanism assembly according to claim 1 , comprising
a further vertical guiding element, and
a further work surface support element engaged with the further vertical guiding element and configured to be movable vertically.
13. The adjustment mechanism assembly according to any claim 1 , comprising at least one mounting support element connected to the vertical guiding element(s) and adapted for mounting the adjustment mechanism assembly.
14. The adjustment mechanism assembly according to claim 1 , wherein the vertical guiding element is:
constant in height; and/or
in itself immobile; and/or
non-contracting and non-extending in its height direction.
15. A wall structure comprising an adjustment mechanism assembly according to claim 1 .
16. The wall structure according to claim 15 , wherein
the adjustment mechanism assembly is mounted to an outer surface of the wall structure.
17. The wall structure according to claim 15 , wherein
the adjustment mechanism assembly is mounted to a mounting surface within the wall structure
such that
the work surface support element(s) extend to outside of the wall structure through vertical slit(s) in the wall structure configured to allow the work surface support element(s) to move vertically.
18. A height-adjustable table comprising
an adjustment mechanism assembly according to claim 1 , and
a work surface supported by the work surface support element(s).
19. The height adjustable table according to claim 18 , comprising
at least one guiding element support member adapted to support the vertical guiding element(s) in an upright position.
