Detailed description of the invention

As observed in Fig. 5 to Fig. 7, desk 1 has desktop 2, and desktop 2 is supported by intersection supporting member 3, intersection supporting member 3 are supported successively by the table leg (showing only one table leg in the every width figure in Fig. 5 to Fig. 7) in four table legs 5.Table leg 5 In each table leg be respectively provided with outer sleeve 6 and interior leg 7.

Most preferably observing as in Fig. 1 and Fig. 2, outer sleeve 6 is provided with the protuberance 16 protruded inwardly from, and this protuberance 16 is preferred Ground is formed by the hollow metal cylinder of outer sleeve 6 is carried out punching press.

Most preferably observing as in Fig. 3 and Fig. 4, interior leg 7 is provided with foot 17 in its lower end.Preferably, foot Portion 17 uses the form that rubber is slightly held or other elastomers are slightly held.It is circular that interior leg 7 preferably has shape of cross section Rod shape.Interior leg 7 is preferably formed through injection-molded by the polypropylene strengthened with long fibre glass reinforcement.Such as Fig. 3 Shown in, be molded in a sidepiece of interior leg 7 is the groove 10 of longitudinal extension, and the groove 10 of this longitudinal extension has one and is The recess 11 that row are regularly spaced apart, each recess in recess 11 all extends from groove 10 on the same side of groove 10.With recess What each recess in 11 was relative is corresponding protuberance protuberance 13, and each protuberance protuberance in protuberance protuberance 13 is all from groove Contrary side align with groove 10 and extend in groove 10.It is adjacent with foot 17 minimum that groove 10 terminates in recess 11 A recess in.

The upper end of groove 10 is formed with unidirectional ramp 14.The effect of unidirectional ramp 14 is that in allowing, leg 7 is pulled to To form table leg 5 in outer sleeve 6.The protuberance 16 of outer sleeve 6 flexibly can engage with unidirectional ramp 14, and therefore including Unidirectional ramp 14 is crossed during being inserted in outer sleeve 6 in the upper end of leg 7.But, once there is this elastic deformation, the most not Again interior leg 7 can be extracted out from outer sleeve 6.This prevent interior leg 7 to depart from outer sleeve in the case of table leg 5 assembles 6.Therefore, ramp 14 is used as unidirectional Anti-fall release mechanism.

It is evident that in the case of protuberance 16 is positioned at groove 10, interior leg 7 can slide in outer sleeve 6.Work as protuberance 16 with a recess in recess 11 relative to time, interior leg 7 can the direction of arrow A along Fig. 5 reverse around its longitudinal axis. In protuberance 16 is positioned at recess 11 by this and thus set the height of table leg 5.Recess 11 and protuberance 16 are preferably shaped to Complementary.Protuberance 16 supports the weight of desk 1 to the joint of the lower limb of relevant recess 11.

On the contrary, interior leg 7 can reverse or rotation along the direction such as arrow B viewed in Fig. 7 around its longitudinal axis Turn, thus protuberance 16 is removed from recess 11 and protuberance 16 is put back into groove 10.Position in protuberance 16 is put back into groove 10 When putting, interior leg 7 can be longitudinally mobile (such as represented by the arrow C in Fig. 6) until protuberance 16 bumps against protuberance protuberance 13 In close on one protuberance protuberance till.This indicates between interior leg 7 moved between recess 11 to user Away from corresponding distance.If this distance is preferable distance, then interior leg 7 is turned round along the direction of the arrow A as represented in Fig. 5 Turn.Alternatively, if it is desired to interior leg moves farther distance, then by interior leg 7 reverse microemulsion in the direction of arrow B in a small amount with Corresponding protuberance protuberance 13 is allowed to cross protuberance 16.This allows interior leg 7 along with protuberance 16 is along the slip of groove 10 along arrow C Direction move, until protuberance 16 runs into next protuberance protuberance 13.

Then, the length of table leg 5 is set, or interior leg 7 continues to move to corresponding another of the spacing between recess 11 One distance.

This torsion or spinning movement are preferably carried out in the case of table leg 5 does not bear any weight.For example, it is possible to rotate Desk 1 makes desktop 2 be vertical, and whole four lower limbs 5 can be regulated to sustained height simultaneously, subsequently can be by desk 1 recovers to its home position.Alternatively, desk lower limb can be lifted away from ground, regulate its length, be then placed back into Ground.The next lower limb of regulation the most similarly, by that analogy, until all lower limbs have been adjusted to preferable height the most.

Observing as in Fig. 4, the spacing between recess 11 is preferably by a series of digital 19 marks forming bar 20 Note, wherein, bar 20 is molded in the other side that the sidepiece from bearing groove 10 of interior leg 7 is different.Therefore, user passes through In observing, this sidepiece of leg 7 is assured that four lower limbs 5 are all adjusted to same length.

Protuberance protuberance 13 provides two useful advantages.First advantage is that protuberance protuberance 13 makes the recess 11 can It is readily positioned.Although recess 11 preferably has the tapered aperture that protuberance 16 provides introducing effect, but highly beneficial Be can make protuberance 16 against protuberance protuberance 13 with leg 7 in retrotorsion, thus know protuberance 16 will thus enter phase The recess 11 answered.Second, protuberance protuberance 13 needs user that interior leg 7 once moves a ladder, the length of this ladder with Distance between protuberance protuberance 13 is corresponding, and the distance between protuberance protuberance 13 is corresponding with the distance between recess 11 again.

It is evident that said apparatus enables the most single desk to be adjusted for the those of ordinary skill of field of furniture Save the arbitrary height to certain altitude, and thus meet the student in the range of between kindergarten and university.Additionally, this The preferred implementation of invention enables desk to be set to, and differing heights is to meet the student taking advantage of wheelchair and to be sitting in different types of Student on seat or chair.If it is required, then numeral 19 can be selected to represent corresponding with set table height Raw " grade ".In Australia, the student of 12 grades is 17 years old or 18 years old, and the student of 7 grades is about 13 years old.

Foregoing describes only an embodiment of the invention, can be to this in the case of without departing substantially from the scope of the present invention Invention is made and significantly being revised for the those of ordinary skill of field of furniture.
