Abstract

A handle assembly is coupled with each of two handle-coupling rods (3) of a stroller or a top stroller. The handle assembly includes a handle (1) and a connecting tube (2). The connecting tube (2) includes an upper end (21) received in the handle (1) and a lower end that receives an upper end of an associated handle-coupling rod. When a button (15) mounted to the handle (1) is pressed, the handle (1) can be turned relative to the connecting tube (2) to a desired orientation. Further, when the button is pressed, the handle and the connecting tube can be jointly moved along a longitudinal direction of the connecting tube, thereby adjusting a level of the handle.

A handle assembly for coupling with each of two handle-coupling rods (3) of a stroller or a toy stroller, each said handle-coupling rod (3) comprising an upper end including at least two vertically spaced transverse positioning holes (31 and 32), the handle assembly comprising:

a connecting tube (2) including an upper end (21) and a lower end that receives an associated one of the handle-coupling rods (3), allowing the connecting tube (2) to move relative to the associated handle-coupling rod along a longitudinal direction of the connecting tube (2), the connecting tube (2) including a longitudinal hole (26) and at least two radial grooves (27) defined in an upper inner periphery delimiting the longitudinal hole (26);
a handle (1) comprising a first end and a second end, a compartment (12) being defined in the first end of the handle (1), a handgrip (11) being formed on the second end of the handle (1), a hole (130) being defined in an upper end wall delimiting the compartment (12), at least two radial grooves (131) being defined in an inner periphery delimiting the hole (130), the handle (1) further including a transverse groove (14) communicated with the hole (130), a button (15) being pivotally received in the transverse groove (14), the upper end (21) of the connecting tube (2) being received in the compartment (12) of the handle (1);
a clutch block (43) received in the upper end (21) of the longitudinal hole (26) of the connecting tube (2), the clutch block (43) including at least two radial extensions (46) extending from an outer periphery thereof, the clutch block (43) further including a longitudinal hole (45);
a first elastic element (44) mounted in the upper end (21) of the connecting tube (2) for biasing the clutch block (43) to a position where said at least two radial extensions (46) are partially received in said at least two radial grooves (131) of the handle (1) and partially received in said at least two radial grooves (27) of the connecting tube (2), allowing joint longitudinal movement of the connecting tube (2) and the handle (1);
a tappet (40) extending through the longitudinal hole (45) of the clutch block (43), the tappet (40) including an upper end (41) abutting against the button (15) and a lower end (42);
a main block (51) mounted in the upper end of the associated handle-coupling rod (3), the main block (51) including an upper longitudinal hole (52), a transverse hole (53) below the upper longitudinal hole (52) and communicated with the upper longitudinal hole, a lower longitudinal hole (57) not aligned with the upper longitudinal hole (52), and a compartment (58) between the lower longitudinal hole (57) and the transverse hole (53);
a positioning member (72) slidably received in the transverse hole (53), the positioning member (72) including an inclined transverse through-hole (74);
a sliding block (60) slidably received in the compartment (58) of the main block (51), the sliding block (60) including an inclined resilient extension rod (62) extending through the inclined transverse through-hole (74) of the positioning member (72) into the upper longitudinal hole (52) of the main block (51), the lower end of the tappet (40) extending into the upper longitudinal hole (52) of the main block (51) and abutting against the inclined resilient extension rod (62);
and
a second elastic element (64) mounted in the lower longitudinal hole (57) of the main block (51) for biasing the sliding block (60) to a position that urges an end (76) of the positioning member (72) into one of said at least one transverse positioning holes (31 and 32) of the associated handle-coupling rod (3);
wherein when the button (15) is pressed, the clutch block (43) slides longitudinally such that said at least two radial extensions (46) of the clutch block (43) are disengaged from said at least two radial grooves (131) of the handle (1) to allow the handle (1) to turn relative to the connecting tube (2) to a desired orientation and that the inclined resilient extension rod (62) is pressed downward and inward to cause the sliding block (60) to slide downward and to cause the end (76) of the positioning member (72) to disengage from the transverse positioning holes (31 and 32), allowing the handle (1), the connecting tube (2), and the main block (51) to move along the longitudinal direction of the connecting tube (2).
