Abstract

Disclosed are telescopic poles and tent frames having telescopic poles. A telescopic pole includes an inner tubular pole, an outer tubular pole, and a locking/unlocking mechanism to control relative movement of the inner and outer tubular poles. The locking/unlocking mechanism is operable between a locking state and an unlocking state. In the locking state, the locking/unlocking mechanism restricts the inner and outer tubular poles from moving toward each other but allows the inner and outer tubular poles to move away from each other. In the unlocking state, the locking/unlocking mechanism allows the inner and outer tubular poles to move toward as well as away from each other.

Dependent claims

A telescopic pole comprising:

an outer tubular pole comprising a first restriction slot formed on a first wall of the outer tubular pole;
an inner tubular pole comprising:
a proximal end disposed inside the outer tubular pole;
a distal end disposed outside the outer tubular pole;
and
a plurality of restriction structures formed at the inner tubular pole between the proximal end and distal end of the inner tubular pole and spaced apart along a length direction of the inner tubular pole, wherein each of the plurality of restriction structures comprises a second restriction slot formed on a first wall of the inner tubular pole that faces the first wall of the outer tubular pole;
and
a locking/unlocking mechanism configured to control movement of the inner tubular pole with respect to the outer tubular pole, the locking/unlocking mechanism comprising:
a base fixedly coupled with the outer tubular pole;
a casing integrally formed or coupled with the base;
a lever pivotally connected to the casing;
and
a locking member pivotally connected to the lever and comprising a first edge sloped along the length direction of the inner tubular pole;
wherein:
the base or the casing comprises a third restriction slot corresponding to the first restriction slot of the outer tubular pole and configured to guide the locking member to move along a width direction of the inner tubular pole between a first position and a second position when the lever pivots relative to the casing;
at the first position, the locking member is inserted into the first restriction slot of the outer tubular pole and the second restriction slot of any one respective restriction structure in the plurality of restriction structures of the inner tubular pole, with a proximal end of the first edge disposed inside of the inner tubular pole and a distal end of the first edge disposed outside the inner tubular pole, thereby restricting the inner tubular pole from moving toward the outer tubular pole along the length direction of the inner tubular pole but allowing the inner tubular pole to move away from the outer tubular pole along the length direction of the inner tubular pole;
and
at the second position, the locking member is removed from the second restriction slot of any one respective restriction structure in the plurality of restriction structures of the inner tubular pole, thereby allowing the inner tubular pole to move away from the outer tubular pole and to move toward the outer tubular pole.

A telescopic pole comprising:

an outer tubular pole comprising a first restriction slot formed on a first wall of the outer tubular pole;
an inner tubular pole comprising:
a proximal end disposed inside the outer tubular pole;
a distal end disposed outside the outer tubular pole;
and
a plurality of restriction structures disposed between the proximal end and distal end of the inner tubular pole and spaced apart along a length direction of the inner tubular pole, wherein the plurality of restriction structures comprises at least 10 restriction structures and distributed over at least half of the inner tubular pole along the length direction of the inner tubular pole, and each of the plurality of restriction structures comprises a second restriction slot;
and
a locking/unlocking mechanism configured to control movement of the inner tubular pole with respect to the outer tubular pole, wherein the locking/unlocking mechanism is operable between a first state and a second state, wherein
at the first state, the locking/unlocking mechanism allows the inner tubular pole to move away from the outer tubular pole along the length direction of the inner tubular pole but restricting the inner tubular pole from moving toward the outer tubular pole along the length direction of the inner tubular pole, and
at the second state, the locking/unlocking mechanism allows the inner tubular pole to move away from the outer tubular pole and to move toward the outer tubular pole.
