Reel device

Abstract

A reel device is provided, including a shell, a knob, an elastic member, a ratchet assembly and a reel unit. The knob is pivoted in the shell along an axial direction and movable to a first position or a second position along the axial direction, and the knob has a first restricting toothed portion. The elastic member is abutted between the shell and the knob so that the knob has a tendency to move toward the first position. The ratchet assembly includes a first ratchet portion and a second ratchet portion, the first ratchet portion is comovable with the knob, and the second ratchet portion is fixedly disposed in the shell. The reel unit is pivoted in the shell for being connected with at least one rope, and the reel unit has a second restricting toothed portion.

What is claimed is: 
     
         1 . A reel device, including:
 a shell;   a knob, pivoted in the shell along an axial direction and movable to a first position or a second position along the axial direction, the knob having a first restricting toothed portion;   an elastic member, abutted between the shell and the knob so that the knob has a tendency to move toward the first position;   a ratchet assembly, including a first ratchet portion and a second ratchet portion, the first ratchet portion being comovable with the knob, the second ratchet portion being fixedly disposed in the shell;   a reel unit, pivoted in the shell for being connected with at least one rope, having a second restricting toothed portion;   wherein when the knob is on the first position, the first and second ratchet portions are meshed with each other, the first and second toothed portions are meshed with each other, and the knob and the reel unit are only unidirectionally rotatable relative to the shell; when the knob is on the second position, the first restricting toothed portion is non-meshed with the second toothed portion, and the reel unit is freely rotatable relative to the shell.   
     
     
         2 . The reel device of  claim 1 , wherein the reel unit includes a plate, the plate has a wrapping shaft for the at least one rope to wrap thereon and at least one receiving space for receiving the at least one rope. 
     
     
         3 . The reel device of  claim 1 , wherein the shell has a cover, the cover has an inner flange, the inner flange defines an opening, the knob has an outer flange, the knob protrudes beyond the opening, and the outer flange is positioned by a side of the inner flange facing the reel unit. 
     
     
         4 . The reel device of  claim 3 , wherein the elastic member is abutted between the inner flange and the outer flange. 
     
     
         5 . The reel device of  claim 1 , wherein the knob has a pivot, the pivot is pivotally disposed on a bottom portion of the shell, a sleeve is sleeved on the pivot and extends along the axial direction toward the reel unit to form the first restricting toothed portion, and the reel unit is sleeved on the pivot and extends along the axial direction toward the first restricting toothed portion to form the second restricting toothed portion. 
     
     
         6 . The reel device of  claim 5 , wherein the first ratchet portion is comovably sleeved on the sleeve, the first ratchet portion includes a plurality of ratchet members, and when the knob is on the first position, the ratchet members are meshed with the second ratchet portion. 
     
     
         7 . The reel device of  claim 6 , wherein an exterior circumferential wall of the sleeve includes a non-circular column, the first ratchet portion has a non-circular hole complemetary to the non-circular column, and the non-circular hole is sleeved on the non-circular column. 
     
     
         8 . The reel device of  claim 1 , wherein the second ratchet portion includes an interior annular toothed plate, the second ratchet portion further has a base plate, and when the knob is on the first position, the first ratchet portion abuts against the base plate. 
     
     
         9 . The reel device of  claim 8 , wherein the interior annular toothed plate has an annular flange facing outside, an interior of the shell has an annular groove, and the annular flange restrictedly abuts against the annular groove. 
     
     
         10 . The reel device of  claim 2 , wherein the shell has a cover, the cover has an inner flange, the inner flange defines an opening, the knob has an outer flange, the knob protrudes beyond the opening, and the outer flange is positioned by a side of the inner flange facing the reel unit; the elastic member is abutted between the inner flange and the outer flange; the knob has a pivot, the pivot is pivotally disposed on a bottom portion of the shell, a sleeve is sleeved on the pivot and extends along the axial direction toward the reel unit to form the first restricting toothed portion, and the reel unit is sleeved on the pivot and extends along the axial direction toward the first restricting toothed portion to form the second restricting toothed portion;
 the first ratchet portion is comovably sleeved on the sleeve, the first ratchet portion includes a plurality of ratchet members, and when the knob is on the first position, the ratchet members are meshed with the second ratchet portion; an exterior circumferential wall of the sleeve includes a non-circular column, the first ratchet portion has a non-circular hole complemetary to the non-circular column, and the non-circular hole is sleeved on the non-circular column; the second ratchet portion is an interior annular toothed plate, the second ratchet portion further has a base plate, and when the knob is on the first position, the first ratchet portion abuts against the base plate; the interior annular toothed plate has an annular flange facing outside, an interior of the shell has an annular groove, and the annular flange restrictedly abuts against the annular groove.
