DESCRIPTION OF THE EMBODIMENTS

[0020] FIG. 1 and FIG. 2 respectively illustrate schematic views of a portable hook and loop strip dispenser according to an embodiment of the disclosure from different viewing angles. FIG. 3 is a schematic view of the portable hook and loop strip dispenser in use. Please refer to FIG. 1 to FIG. 3 at the same time. In this embodiment, a portable hook and loop strip dispenser 100 (hereinafter referred to as the dispenser 100) provides a hook and loop strip 200 carried thereon in a rolled state, as shown in FIG. 3. The dispenser 100 includes a base 110 and a protrusion column 113 thereon. A roll portion 210 of the hook and loop strip 200 is sleeved on the protrusion column 113 and is further held by a movable claw 120 to be fixed on the base 110. When the user carries the base 110, the hook and loop strip 200 does not fall off.

[0021] FIG. 4A is an exploded view of the portable hook and loop strip dispenser. Please refer to FIG. 4A. In this embodiment, the dispenser 100 includes the movable claw 120, a button 130, a spring 150, and the base 110. The base 110 is formed by an upper shell 111 and a lower shell 112, and a protrusion column 113 extends and protrudes from the upper shell 111. The movable claw 120 is liftably disposed in the protrusion column 113, and a claw hook 122 of the movable claw 120 is extended out of the protrusion column 113 or is retracted into the protrusion column 113 along with the movable claw 120 lifting or lowering in the protrusion column 113. Furthermore, the protruding column 113 has a slope 113f to facilitate the roll portion 210 to bear thereon.

[0022] FIG. 4B to FIG. 4D are enlarged schematic views of some components of FIG. 4A. Please refer to FIG. 4A to FIG. 4C. Further, the protruding column 113 of this embodiment has a top portion 113b and an inner column 113c and an outer column 113a coaxially disposed with respect to an axis CX. The roll portion 210 is sleeved onto the outer column 113a. The outer column 113a covers the inner column 113c. The movable claw 120 has a sleeve 121 and an elastic arm 123. The sleeve 121 is coaxially disposed with respect to the axis CX and movably sleeved onto the inner column 113c. The elastic arm 123 extends from the sleeve 121. The claw hook 122 is located at a distal end of the elastic arm 123 away from the sleeve 121. The button 130 is coaxially borne on the sleeve 121 with respect to the axis (CX). Furthermore, the outer column 113a has a receiving groove 113e facing the inner column 113c. The protrusion column 113 has a stopper block 113d located between the inner column 113c and the outer column 113a and misaligned with the receiving groove 113e. The elastic arm 123 of the movable claw 120 is located in the receiving groove 113e. The spring 150 is disposed in the inner column 113c and abuts between a bottom surface of the inner column 113c and the sleeve 121. Here, the elastic force of the spring 150 constantly drives the movable claw 120 to lift in the protruding column 113, that is, to drive the movable claw 120 and the button 130 thereon away from the bottom surface of the inner column 113c.

[0023] FIG. 5A and FIG. 5B illustrate partial schematic views of the portable hook and loop strip dispenser. Please refer to FIG. 5A and FIG. 5B at the same time, and compare with FIG. 4B. In this embodiment, the button 130 is rotatably and liftably disposed on the protrusion column 113 and borne on the movable claw 120, in which the button 130 is in a locked state (FIG. 5A) or an unlocked state (FIG. 5B) due to the rotation. In detail, the button 130 has a pressing portion 131 and a stopping portion 132. The stopping portion 132 radially extends from the periphery of the pressing portion 131. The pressing portion 131 passes through and protrudes from the top portion 113b of the outer column 113a.

[0024] FIG. 6A and FIG. 6B illustrate partial cross-sectional views of the portable hook and loop strip dispenser. Please refer to FIG. 5A and FIG. 6A. The button 130 shown in the two drawings is in the locked state. At this time, the movable claw 120 is driven by the spring 150 to abut upward, that is, the movable claw 120 is driven and the button 130 is linked to the movement to lift in the protrusion column 113. Therefore, the stopping portion 132 of the button 130 abuts against the top portion 113b of the outer column 113a, thereby the button 130 is prevented from falling off from the protrusion column 113. At the same time, it should be noted that, at this time the stopper block 113d is located on a lowering path of the stopping portion 132. Therefore, even if force is applied to the pressing portion 131 to press down, the pressing operation cannot be performed due to the presence of the stopper block 113d, so as to ensure and maintain the locked state. In addition, at this time, the claw hook 122 of the movable claw 120 protrudes from the column surface of the outer column 113a. Therefore, when the roll portion 210 is sleeved onto the protrusion column 113 as shown in FIG. 3, the claw hook 122 may smoothly hold and fix the roll portion 210 on the protrusion column 113 and the base 110.

[0025] Next, please refer to FIG. 5B and FIG. 6B. The button in the two drawings is rotated and moved away from the stopper block 113d (for example, as shown by a dotted arrow in FIG. 5B, at this time, the stopping portion 132 moves to the receiving groove 113e and is located above the elastic arm 123), that is to say, the stopper block 113d is no longer on the lowering path of the stopping portion 132. Therefore, at this time, when a user applies force to the pressing portion 131, the button 130 may be smoothly driven to lower, the sleeve 121 of the movable claw 120 is also linked to the movement to lower along the inner column 113c at the same time, and the spring 150 is deformed at the same time. As mentioned above, the sleeve 121 and the claw hook 122 are connected by the elastic arm 123. Therefore, as the sleeve 121 lowers, the elastic arm 123 folds and deforms toward the sleeve 121, thereby driving the claw hook 122 to retract into the outer column 113a. Therefore, the roll portion 210 held by the outer column 113a as mentioned above may be released, which allows the user to take the roll portion 210 out from the dispenser 100.

[0026] Correspondingly, when the user stops applying force to the button 130, the elastic force generated by the deformation of the spring 150 may smoothly drive the movable claw 120 and the button 130 to reset and return to the state shown in FIG. 6A from the state shown in FIG. 6B. At this time, if the roll portion 210 is sleeved on the outer column 113a, then the roll portion 210 is held by the claw hook 122 again. At the same time, the user may rotate the button 130 again to return the button 130 from the unlocked state shown in FIG. 5B to the locked state shown in FIG. 5A to facilitate firm placement of the hook and loop strip 200 on the dispenser 100.

[0027] Please refer to FIG. 3, FIG. 4A, and FIG. 4D at the same time. In this embodiment, the dispenser 100 further includes a latch assembly 160, the base 110 further has a turning wall 114, and the latch assembly 160 is disposed next to the turning wall 114. A ribbon portion 220 of the hook and loop strip 200 passes through the turning wall 114 along a path L1 and turns after extending from the roll portion 210. Furthermore, the latch assembly 160 has one-way teeth 161b, and the one-way teeth 161b are along the path L1, so that the ribbon portion 220 may be temporarily fixed by the one-way teeth 161b when passing through the turning wall 114.

[0028] Furthermore, the latch assembly 160 includes a latch member 161, a torsion spring 162, and a pivot shaft 163. The latch member 161 is freely pivoted on the base 110 through the pivot shaft 163 to facilitate pivoting rotation around a direction one D1 or a direction two D2. The latch member 161 is generally in the shape of a mallet and has the one-way teeth 161b on a head portion of the mallet. In addition to allowing the pivot shaft 163 to be disposed and placed in a pivot hole 111b, a handle portion of the latch member 161 further has a guiding groove 161e, and the base 110 has a guiding column 111a coupled to the guiding groove 161e to provide a guiding effect when the latch member 161 rotates with respect to the base 110.

[0029] Furthermore, the torsion spring 162 abuts between the base 110 and the latch member 161, and the torsion spring 162 constantly drives the latch member 161 to rotate in the direction two D2, in which the path L1 is a tangential direction of the direction one D1, and the direction one D1 and the direction two D2 are opposite to each other. Further, the torsion spring 162 includes a center 162a and two end portions 162b and 162c, in which the pivot shaft 163 passes through the center 162a and the center 162a is stored inside the bottom of the latch member 161, the end portion 162b extends from the center 162a and passes through an opening 161d of the handle portion and abuts against the head portion of the mallet, while the end portion 162c extends from the center 162a and passes through an opening 161c of the handle portion and abuts against the protrusion column of the base 110 (as shown in FIG. 4D, located on the lower right side of the guiding column 111a).

[0030] In this way, when the user applies force to pull the ribbon portion 220, the operation is equivalent to allow the ribbon portion 220 to move along the path L1, which is equivalent to pull the hook and loop strip 200 from the roll portion 210. Therefore, the latch member 161 may be linked to the movement along the path to pivot around the direction D1, and since being along the path, the ribbon portion 220 may smoothly pass through the one-way teeth 161b. At the same time, the latch member 161 pivoting around the direction one D1 deforms the torsion spring 162 at the same time. In contrast, when the user no longer applies the force to pull the ribbon portion 220 as mentioned above, the elastic force of the torsion spring 162 drives the latch member 161 to pivot around the direction two D2, and allow the one-way teeth 161b to temporarily hold the ribbon portion 220, so as to achieve a temporary fixed effect to the hook and loop strip 200 regarding the ribbon portion 220 pulled from the roll portion 210.

[0031] In a well-known manner, the hook and loop strip 200 is a fiber fastener whose surface has hooks (also referred to as hook surface) and loops (also referred to as loop surface). FIG. 4E is a partial schematic view of a dispenser according to another embodiment of the disclosure. FIG. 4F is a corresponding schematic view of the damper wheel and the hook and loop strip of FIG. 4E. Please refer to FIG. 4E and FIG. 4F. In this embodiment, in addition to the same latch assembly 160 as the previous embodiments, the dispenser further includes a damper wheel 160A pivoted on the upper shell 111, and a column surface of the damper wheel 160A has a hook-like structure 164, so as to be correspondingly engaged with the loop-like structure of the hook and loop strip 200, so as to achieve the engaging effect produced by the one-way teeth 161b. In FIG. 4F, different cross-section patterns are used to represent the hook-like structure 164 and the loop-like structure. Similarly, if the hook-like structure 164 of the hook and loop strip 200 faces the damper wheel 160A, then the column surface of the damper wheel 160A is changed to the loop-like structure.

[0032] On the other hand, in other embodiments not shown, the damper wheel 160A may also replace the latch assembly 160, or the one-way teeth 161b of the latch assembly 160 may be replaced with the column surface of the damper wheel 160A, that is, the hook-like structure 164 or the loop-like structure is disposed on the head portion of the mallet of the latch member 161 to replace the one-way teeth 161b.

[0033] FIG. 4G is a partial schematic view of the dispenser according to another embodiment of the disclosure. FIG. 4H is a schematic view of an elastic piece of FIG. 4G. Please refer to FIG. 4G and FIG. 4H at the same time. Different from the previous embodiments, a latch assembly 160B of this embodiment includes a fixed shaft 165 and an elastic piece 166, in which the fixed shaft 165 is fixedly disposed on the upper shell 111, and the elastic piece 166 is in the shape of and includes roll portions 166a, 166b and a bending portion 166c, the roll portion 166a is sleeved onto and fixed on a protrusion column 111c of the upper shell 111, and the bending portion 166c is sleeved onto the fixed shaft 165 and is limited by the fixed shaft 165. The bending portion 166c is further divided into segments C1, C2, C3, in which the segment C1 is connected to the roll portion 166a, the segment C3 is connected to the roll portion 166b, and the segment C2 abuts against the fixed shaft 165 and connected between the segments C1, C3.

[0034] Due to the fixation of the roll portion 166a and the abutting and limiting of the fixed shaft 165, the elastic piece 166 has a free end in the segment C3 and the roll portion 166b and has the characteristic of elastic deformation. More importantly, the elastic piece 166 further has a protrusion 166d located at the roll portion 166b, which corresponds to the hook and loop strip 200 (as shown in the previous embodiments) and provides an engaging force opposite to the path L1, so as to smoothly provide engagement for the hook and loop strip 200 and prevent from moving in an opposite direction (opposite to the path L1). Here, the protrusion 166d is formed by, for example, punching and bending the elastic piece 166 at the roll portion 166b, but the disclosure is not limited thereto.

[0035] FIG. 7A and FIG. 7B are partial schematic views of the portable hook and loop strip dispenser. Please refer to FIG. 4A, FIG. 7A, and FIG. 7B at the same time. The dispenser 100 further includes a cutting assembly 140, the ribbon portion 220 of the hook and loop strip 200 passes through the turning wall 114 along the path L1 and turns and then goes to the cutting assembly 140 after pulling out and extending from the roll portion 210, so that the user may cut the ribbon portion 220 through the cutting assembly 140. Furthermore, the cutting assembly 140 includes holders 143, 144 and cutting blades 141, 142 movably disposed in the holders 143, 144, in which the cutting blade 142 fixed in the holders 143, 144 and the other cutting blade 141 movably disposed in the holders 143, 144 are included, in which a blade 141b is penetrated by a pivot shaft 145 so that the ribbon portion 220 may be cut by the cutting blades 141, 142 when passing through the holders 143, 144. In this embodiment, the cutting blade 141 includes the blade 141b and a handle 141a, in which the blade 141b is pivotally connected to the cutting blade 142 through the pivot shaft 145, and the handle 141a is exposed outside the holders 143, 144 to facilitate operation for the user.

[0036] Please refer to FIG. 2 and FIG. 4A again. In this embodiment, the dispenser 100 further includes a back clip 170 and a magnet 180 disposed on the base 110 and facing away from the protrusion column 113, in which the back clip 170 has an engaging interface 173 and clip pieces 171, 172. The engaging interface 173 is installed on an engaging block 112a of the lower shell 112, and due to the assembly of the upper shell 111 and the lower shell 112, part of the clip piece 171 is clamped therein to complete the assembly of the back clip 170 and the base 110. As shown in FIG. 2, the portion of the back clip 170 exposed from the base 110 allows the user to wear the dispenser 100 on the body or clothing, thereby portable carrying the hook and loop strip 200 is facilitated. Similarly, the magnet 180 is also used to allow the base 110 to be attached or fixed on an object having magnetic permeability, and can also provide convenience during operation of the dispenser 100.

[0037] On the other hand, the base 110 of this embodiment further has a holding portion 115, which is helpful for the user to hold the base 110 firmly during operation, and also improves the convenience of the dispenser 100.

[0038] In summary, in the above-mentioned embodiments of the disclosure, the dispenser is disposed with the protrusion column on the base thereof that can accommodate the roll portion of the hook and loop strip, and is disposed with the movable claw, the button, and the spring on the protrusion column together. Accordingly, the protrusion column may not only be used for the roll portion to be sleeved thereon, but also can stop, hold, or release the roll portion through the claw hook of the movable claw, so that when the roll portion is held by the claw hook, the hook and loop strip is firmly disposed on the base and does not fall from the dispenser during portable carrying of the user.

[0039] The button is rotatably and liftably disposed on the protrusion column, so with the stopper block on the protrusion column, the button may be switched between the locked state and the unlocked state due to rotation. In the unlocked state, the stopper block moves away from the lowering path of the button, so that the button is pressed and drives the movable claw. Then, the claw hook of the movable claw is connected to the sleeve through the elastic arm, so when the button drives the sleeve to lower, the elastic arm deforms and folds toward the sleeve to facilitate driving the claw hook to retract into the protrusion column. In contrast, when the sleeve lifts, then it means that the elastic arm may expand with respect to the sleeve and allow the claw hook to be exposed from the column surface of the protrusion column again.

[0040] Furthermore, after the roll portion is sleeved on the protrusion column, the user may pull the ribbon portion from the roll portion and at the same time cut the ribbon portion through the cutting assembly at the cutting place after passing through the turning wall. Simply put, the dispenser provides carrying and cutting functions for the hook and loop strip accordingly, which facilitates operation for the user. Regarding the ribbon portion passing through the turning wall, the disclosure may also be temporarily fix the ribbon portion through the latch assembly to facilitate subsequent cutting of the ribbon portion. In addition, the dispenser is further disposed with the holding portion, the back clip, and the magnetic on the base, which not only facilitates operation for the user, but also provides portability.
