Abstract
There is provided a height adjustable seat post, comprising: an inner telescopic member, and an outer telescopic member, the telescopic members being adapted to restrict relative rotation. Within the members there is a threaded spindle, the spindle being axially restricted at the lower end of the outer member, and realisably rotatable therewith. At a top end of the inner telescopic member there is provided means to attach a seat. At the bottom end, the inner telescopic member has complementarity threading with respect to the spindle. Resilient means are provided for moving the inner telescopic member outwards upon triggering.
Claims (19)
1. A height adjustable seat post, comprising: â ¢ an inner telescopic member adapted to support a seat or handlebars, and · an outer telescopic member, â ¢ a spindle within the members for determining the extension of the inner member relative to the outer member, â ¢ the spindle having a fast lead thread such as to turn upon application of longitudinal force, the spindle being threadedly engaged with one member and thrustingly journaled with the other member. â ¢ resilient means for urging the inner telescopic member outwards for extension of the post and lifting of the seat, and â ¢ a releasable lock for locking the spindle against rotation and extension of the post, the arrangement allowing, when the lock is released, for a rider to depress the seat with his/her weight, or to permit the resilient means to Hit the seat, the seat being retained in position when the lock is reapplied.
2. A height adjustable seat post as claimed in claim 1, wherein the inner and outer telescopic members are restricted from relative rotation by using one or more keys and keyways, with the key being on the inner member and the key way being on the outer member, or vice versa.
3. A height adjustable seat post as claimed in claim 1 or claim 2, wherein the inner member is adapted to receive the spindle at its lower end via a fixed nut fused to it, wherein the fixed nut is threaded complimentarily to the spindle, or the internal diameter of the telescopic member is threaded.
4. A height adjustable seat post as claimed in any preceding claim, wherein the lower end of the spindle is adapted to engage with the locking means.
5. A height adjustable seat post as claimed in claim 4 wherein a housing is provided for the releasable locking means, and a triggering means, the housing coupling to the bottom end of the outer telescopic member.
6. A height adjustable seat post as claimed in any preceding claim, wherein the inner and/or outer telescopic member comprise bearings to aid sliding of the telescopic members relative to each other.
7. A height adjustable seat post as claimed in claim 6, wherein the housing has a shaped lower portion such that the nut has a substantially tight fit.
8. A height adjustable seat post as claimed in claim 7, wherein the shaped lower portion is at least partially deeper than the nut or equivalent component.
9. A height adjustable seat post as claimed in claim 5, wherein the triggering means acting upon the locking means is a Bowden cable.
10. A height adjustable seat post as claimed in claim 8 wherein a spring is disposed beneath the locking means such that when the triggering means is released the locking means re-engage with the lower end of the spindle.
11. A height adjustable seat post as claimed in any preceding claim, wherein the resilient means are a spring, or an arrangement of a sealed piston used to create an air chamber.
12. A height adjustable seat post as claimed in any preceding claim, wherein the resilient means are of sufficient strength to urge the inner telescopic member outwards when there is no or little load atop the inner telescopic member.
13. A height adjustable seat post as claimed in any preceding claim, wherein the resilient means are situated around the spindle, or within the inner telescopic member.
14. A height adjustable seat post as claimed in any preceding claim, wherein the spindle has a range of 4-12 threads per inch.
15. A height adjustable seat post as claimed in any preceding claim, wherein the spindle has multi start threading in the range of 4 to 12 starts.
16. A height adjustable seat post as claimed in any preceding claim, wherein the lead of each thread is between 15mm and 35mm.
17. A height adjustable seat post as claimed in any preceding claim, wherein the pitch of the threading is between 1mm and 3mm.
18. A height adjustable seat post as claimed in any preceding claim, wherein the lock is at a journaled end of the spindle.
19. A height adjustable seat post as claimed in any preceding claim, wherein the spindle is threaded with a helix angle of over 30°.
