Support device for a child vehicle safety seat
First Claim
1. A support device for a child vehicle safety seat, said support device comprising:
- a positioning tube having a first tube portion adapted to be connected to the child vehicle safety seat, and a second tube portion opposite to said first tube portion, said positioning tube being formed with a plurality of positioning hole units spaced apart from each other along a tube axis, each of said positioning hole units including a pair of positioning holes that are disposed at diametrically opposite positions relative to the tube axis;
a support tube sleeved telescopically on said second tube portion of said positioning tube and formed with a pair of through holes that are disposed at diametrically opposite positions relative to the tube axis;
a support base sleeved on said support tube, and having a mounting seat disposed at a horizontal level corresponding to said through holes in said support tube; and
a seat height adjusting unit includingan actuator mounted movably in said mounting seat and having a pair of extending arms respectively disposed at opposite lateral sides of said support tube, and a pair of protruding members each disposed at a respective one of said extending arms, said protruding members being extendible into said through holes and said positioning holes of a registered one of said positioning hole units to retain said positioning tube at a desired extended length relative to said support tube, anda spring member disposed in said mounting seat for applying a biasing force to said actuator.

Abstract
A support device includes a positioning tube to be connected to a child vehicle safety seat and formed with a plurality of positioning hole units. A support tube is sleeved telescopically on the positioning tube and is formed with a pair of through holes. A support base is sleeved on the support tube, and has a mounting seat disposed at a horizontal level corresponding to the through holes. A seat height adjusting unit includes an actuator that is mounted movably in the mounting seat, that is biased by a spring member, and that engages removably the through holes and a registered one of the positioning hole units to retain the positioning tube at a desired extended length relative to the support tube.

12. A support device comprising:
-
a positioning tube formed with a plurality of positioning hole units spaced apart from each other along a tube axis, each of said positioning hole units including a pair of positioning holes that are disposed at diametrically opposite positions relative to the tube axis; a support member sleeved telescopically on said positioning tube and formed with a pair of through holes that are disposed at diametrically opposite positions relative to the tube axis, said support member having a mounting seat disposed at a horizontal level corresponding to said through holes; and an actuator mounted movably in said mounting seat and having two protruding portions that correspond respectively in position to said through holes, said actuator being biased for movement between a locking position, where said protruding portions engage said through holes and said positioning holes of a registered one of said positioning hole units to retain said positioning tube at a desired extended length relative to said support member, and an unlocking position, where said protruding portions are disengaged from said through holes and said positioning holes of said positioning hole units to permit adjustment of the extended length of said positioning tube relative to said support member. - View Dependent Claims (13, 14)
