Description
- 1. Technical Field
- The present invention relates to a twisting mechanism for a duster and, more particularly, to a mechanism for twisting a dusting cloth of the duster and retaining the dusting cloth at a twisted position.
- 2. Description of Related Art
- A conventional duster is typically composed of a distinctive dusting cloth capable of attracting dust and a fixture for bracing and holding the dusting cloth. To prepare the duster for dusting operation, the front end of the fixture is inserted into the dusting cloth in the manner that the rear end of the dusting cloth can be coupled with hooks provided at the middle portion of the fixture. Thereby, the dusting cloth can be spread and stretched, so that a user can hold the fixture at its rear end and wield the duster for implementing the dusting cloth to attract dust.
- Such conventional duster functions for attracting dust in virtue of the positive-charged fluff layer at the surface of the dusting cloth attracting negative-charged dust. However, since the fluff layer can only be presented at the surface (the upper and lower surfaces) of the dusting cloth, dead spots of the duster tend to occur when the duster contacts diversified surface angles of objects to be cleaned. To ensure complete dusting, a user has to continually maintain a particular relative angle between the fluff level and the surfaces of objects to be cleaned. This may not only unnecessarily consume dusting time, but also render a user's wrist discomfort after his/her long-term dusting operation.
- To remedy the foresaid problem, a rotary duster has been disclosed by Taiwan Patent Application 093132036, which belongs to the same assignee as that of the present invention.

Further, a layer of heat-fusible intermingled yarn and another electrostatic non-woven sheet are stacked to both sides of the meshed non-woven sheet. Then hot-pressing process can be again employed to integrate the stacked sheets as the dustingcloth 50 that have eight layers of non-woven fabrics or yarn. Anaccommodating recess 51 may be defined at the middle portion of the dustingcloth 50 by means of hot-pressing process for allowing the fixture to be settled therein so that the dusting cloth can be fully braced. The prior-art fixture 60 is primarily composed of ahandle 61, acurved rod 62 settled at one end of thehandle 61, an adaptive coupler pivotally connected with thecurved rod 62 and atwisting shaft 63 attached to the other end of the adaptive coupler. Therein, spiral spines 631 are provided at the surface of thetwisting shaft 63, as shown inFIG. 1 , and a fork portion is formed at the tip of thetwisting shaft 63 for inserting into theaccommodating recess 51 and being coupled with the end of theaccommodating recess 51 so that the front end of the front end of the dustingcloth 50 adjacent to the end of theaccommodating recess 51 can be fastened to thetwisting shaft 63. Subsequently, a user can use his/her hand to wring the middle portion of the dustingcloth 50 along the spiral spines 631 of thetwisting shaft 63 to endow the dustingcloth 50 with a spiral shape having a 360-degree dusting surface, as shown inFIG. 2 . Hence, the user can easily grasp thehandle 61 and wield the duster along a single direction to have the twisteddusting cloth 50 dust objects with various-angled surfaces so that the dusting efficiency is consequently enhanced. - Though the prior-art rotary duster might satisfy the need of effective dusting, some problems may need to be solved for the optimum practical use thereof. One disadvantage of the prior-art rotary duster is that to endow the dusting cloth with the 360-degree dusting surface, the user's hand has to directly touch and wring the surface of the dusting cloth along the spiral spine of the twisting shaft and this may cause the user's hand stained. Further, during dusting, the dusting cloth is liable to reversely rotate to its initial flat position due to its own tension. At this time, the user's re-rotating the dusting cloth can undesirably render the dust collected at the dusting cloth scattered to the ground again.

- Please refer to
FIGS. 1 through 7 for a twisting mechanism for a duster according to the present invention, which primarily comprises abrace 10, arotating mechanism 20 and ahandle 30. - The
brace 10 is substantially acolumn 11, wherein a plurality ofspiral spines 12 are provided at the surface of thecolumn 11 for guiding the twisting direction of the dusting cloth C and afork portion 111 is formed at the tip of thecolumn 11 for coupling with the end of the accommodating recess C1, as shown inFIG. 4 , so that the front end of the dusting cloth C adjacent to thefork portion 111 is set as a fixed end. - The
rotating mechanism 20 is pivotally connected to the rear end of thebrace 10 and afirst hook assembly 21 as well as asecond hook assembly 22 are provided at the surface thereof, wherein the distance L1 between thefirst hook assembly 21 and the tip of thebrace 10 is smaller than the distance L2 between thesecond hook assembly 22 and the tip of thebrace 10 whereby the rear end of the dusting cloth C can be hooked and set as a rotatable end. Thus, the rear end of the dusting cloth C, which possesses a relatively smaller length, can be hooked at thefirst hook assembly 21, as shown inFIG. 4 . Alternatively, the rear end of the dusting cloth C, which possesses a relatively greater length, can be hooked at the second hook assembly 22 (not shown). According to the present embodiment, each of thefirst hook assembly 21 and thesecond hook assembly 22 is composed of at least two hooks (211, 221) wherein each said hook is arranged at one of the opposite sides of therotating mechanism 20, respectively. When therotating mechanism 20 is rotated clockwise or anticlockwise with respect to thebrace 10, the hooks can pull the rotatable end of the dusting cloth C to rotate with respect to the surface of thebrace 10 so that the middle portion between the fixed end and the rotatable end of the dusting cloth C can be shaped corresponding to thespiral spines 12 at the surface of thebrace 10 into a spiral shape having a 360-degree dusting surface, as shown inFIG. 5 . Thus, the rotational direction of therotating mechanism 20 has to be set corresponding to the extending direction of thespiral spines 12. That is to say, when thespiral spines 12 are laid out as an S shape extending from the lower-right to the upper-left, therotating mechanism 20 shall be correspondingly set as clockwise rotatable. Alternatively, when thespiral spines 12 are laid out as a Z shape extending from the lower-left to the upper-right, as shown inFIG. 4 , therotating mechanism 20 shall be correspondingly set as anticlockwise rotatable. - The
handle 30 is provided at the rear end of therotating mechanism 20 and has a diameter greater than or equal to that of therotating mechanism 20 for being held and wielded by a user. Further, acoupling structure 31 may be provided at the rear end of thehandle 30 for connecting with an extension structure, such as anextension rod 40, as shown inFIG. 7 . An alternative embodiment of thecoupling structure 31, as shown inFIG. 6 , may comprise arecess 311 passing through the upper and lower surfaces of the rear end of thehandle 30 for pivotally receiving theextension rod 40. Each of the left and right walls of therecess 311 hasplural positioning protrusions 312 facing those of the other, respectively, and meantime, the front end of theextension rod 40 has plural positioneddents 401 corresponding to the positioningprotrusions 312 for controlling the angle between theimmovable handle 30 and theextension rod 40. Thereby, the angle θ between thehandle 30 and theextension rod 40 can be adjusted steppedly to facilitating reaching an enhanced dusting altitude or distance. Theextension rod 40 in the present embodiment is a telescopic extension rod, which is composed of a plurality of telescoped sleeves. - Please refer back to
FIGS. 4 through 6 again. To install the dusting cloth C on the twisting mechanism, thebrace 10 is firstly inserted into the accommodating recess C1 of the dusting cloth C, and thefork portion 111 at the tip of thebrace 10 is coupled with the accommodating recess C1. Then the side of the dusting cloth C adjacent to the end of the accommodating recess C1 is therefore set as a fixed end. Subsequently, the opposite end of the dusting cloth C is hooked by either thefirst hook assembly 21 or thesecond hook assembly 22 of therotating mechanism 20, depending on the length of the dusting cloth C, so that the dusting cloth C can be spread and attached to thebrace 10. At this time, a user can easily rotate therotating mechanism 20 adjacent to thebrace 10 to make the hook assembly drive the rotatable end to rotate. As a result, the middle portion of the dusting cloth C can be twisted along the extending direction of thespiral spines 12 of thebrace 10 into a spiral shape having a 360-degree dusting surface. Thereupon, the assembly and configuration of the disclosed subject and the dusting cloth C can be accomplished. As the user is free from touching the surface of the dusting cloth for twisting the dusting cloth directly, his/her hand can be kept clean. - Besides, the twisting mechanism of the present invention is a unidirectional
rotating mechanism 20 and the rotating direction of therotating mechanism 20 is set corresponding to the extending direction of thespiral spines 12. Therefore, when thebrace 10 rotates the rotatable end of the dusting cloth C clockwise or anticlockwise, the dusting cloth can be twisted along the extending direction of thespiral spines 12 into a spiral shape have a 360-degree dusting surface, which allows a user to dust with improved efficiency. As the dusting cloth C is twisted into the spiral shape, the unidirectionalrotating mechanism 20 facilitates retaining the rotatable end of the dusting cloth C at the rotated position and counteracting the tension of the dusting cloth C so as to maintain the spiral shape of the dusting cloth C. - Although a particular embodiment of the invention has been described in detail for purposes of illustration, it will be understood by one of ordinary skill in the art that numerous variations will be possible to the disclosed embodiments without going outside the scope of the invention as disclosed in the claims.
