Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that is easy to manufacture and highly efficient, and a method for manufacturing the same.

In general, a duster is a cleaning tool that removes stagnant dust by dusting, but conventional duster cleaning only scatters stagnant dust and removes dust floating in the air. The project once again became stagnant and was unable to achieve its intended purpose.

In addition, because the working part was poorly used, the handle could hit or scrape, causing damage to furniture and car walls. In order to deal with the above-mentioned problem, processed threads with high static electricity generation efficiency, such as crimped polypropylene that is crimped to form a net shape when expanded, are lined up in parallel, stitched at both ends and at the center, and stitched selvedges are created. The process of creating a band-like tuft with both ends temporarily fixed by the stitch selvedge and the holding thread by cutting between the two center holding threads, and the process of creating a band-like tuft with a stitch selvage and a holding thread, and a process of creating a band-like tuft with an interrupted part at the tip and a The process of constructing the handle with clasp holes provided at appropriate locations on the insert and at locations away from the insert, and the step of stitching a band-like tassel onto the insert of the handle and inserting it to secure the ears. Holding the handle, pass through the inside of the stitch selvage, insert and fix a split pin into the clasp hole to form a winding start part, and roll down the stitch selvage of the band-shaped foot part in a spiral in the longitudinal direction of the handle. a step of removing the holding thread;
A method of manufacturing dusters, which consists of the steps of penetrating and fixing the top of the stitch and the clasp hole with a cotter pin at the end of the winding, and inserting a trumpet-shaped cap, is known, for example, from 1987-6.
It is published as No. 0863.

However, in this case, the stitching selvage does not have sufficient fall strength against the tip of the handle, so there is a risk that the wrapping end of the tassel may separate from the handle, and the wrapping of the tassel cannot be done reliably. However, there is a disadvantage that it is difficult to remove the stitch presser thread.

The present invention eliminates the above-mentioned drawbacks, and makes the stitch selvedge sufficiently tight against the wrap-around portion of the tip of the handle to prevent the wrapped end of the tassel from separating from the handle, and also prevents the wrapped end of the tassel from separating from the handle. To provide a duster and a method for manufacturing the same, which facilitates winding work by ensuring the starting position of winding with respect to a handle, and facilitates removal of stitch presser threads.

Next, the present invention will be explained along with embodiments shown in the drawings.
The duster of this invention has a cut-in part 2 on the head, and a handle part A made of hard vinyl chloride, wood, etc., with clasp holes 3 and 4 provided at appropriate locations on the cut-in part 2 and in parts away from the cut-in part 2; It is made of a material with high static electricity generation efficiency such as polypropylene, and consists of a belt-like tuft B made of a wound striped yarn 6 that becomes a net shape when expanded, and a trumpet-like cap 5 to securely stop the belt-like tuft B. .

The base fabric constituting the band-like tuft B is made of a material with high static electricity generation efficiency such as polypropylene. The crimped yarns 6, which become net-like when expanded, are arranged in parallel, and both ends are temporarily fastened with chain stitches 7, and the central part is Temporarily fasten with two chain stitches that serve as holding threads 8.

By cutting the holding threads 8, 8 of the base fabric constructed in this way, chain stitches 7,
8, a temporarily fixed band-shaped tuft B is obtained. Next, the method of constructing the duster of the present invention by the handle part A and the band-like tuft part B will be described.
Fold the tip of the tassel B temporarily fixed in quarters to an appropriate length, insert it into the cut-in part 2 at the tip of the handle as if fixing the chain stitch ear 7, and insert the split pin 10 into the clasp hole to tighten the chain stitch ear. 7, and fold the end of the cotter pin to secure the beginning of winding the belt-like belt B around the handle A.

The tassel part B is applied to the top of the handle part A two to three times, and adhesive is applied onto the chain stitch selvedge 7 to securely fix the stitching start part. Then, the chain stitch selvage 7 of the band-like tuft B is rolled down in a spiral along the longitudinal direction of the handle A. In this case, the cleaning effect will be further increased by spreading the particles as densely as possible. The flap end is fixed by inserting a split pin 10 into the clasp hole 4 provided at the required length of the flap so as to pass over the chain stitch selvage 7 of the flap. Next, the holding string 8 that temporarily fixed the end of the tassel is removed to form a bulky tassel.
Then, a trumpet-shaped cap 5 is inserted onto the end fixing portion, and a cap 9 is attached to the end of the handle to complete the duster of the present invention. This invention is constructed as described above, and when constructing the bellows, a material with high static electricity generation efficiency is used and a crimped processed yarn is used, which may be different from other materials. However, with the method of this invention, it is difficult to handle as it sticks or falls apart.
Since chain stitches 7 and 8 are applied, handling is extremely simple, and when unnecessary, the presser thread can be easily removed by tightening the seam end of the chain stitch.

In addition, the duster is constructed by simply wrapping the tassel around the handle, making it extremely easy to manufacture.
The ends can be securely fixed by passing the chain stitch over the ears with a split pin, and there is no inconvenience like the head slipping out as with conventional methods. In addition, since the material is made of a material with high static electricity generation efficiency such as polypropylene, it completely fulfills its intended cleaning purpose as a duster without scattering dust.
In addition, since it is wrapped in a bellows, it is bulky and generates a lot of static electricity, and it also prevents damage to the parts to be cleaned such as furniture and cars.

In addition, when the processed yarn is expanded, it becomes net-like and has been subjected to a winding process, so the more it is used, the more it intertwines and becomes bulky, creating a soft feel. , it provides an innovative function that goes beyond the sense of traditional dusters in terms of decoration. In particular, in the duster of the present invention, the stitching selvedge of the flange, which is held in the folded part at the tip of the handle, is folded multiple times, so that the pinching is reliable and the beginning of winding of the tassel is aligned with the handle. Furthermore, since adhesive is applied to the beginning of winding the tassel around the handle, there is no movement of the beginning of winding of the tassel when wrapping the tassel around the handle, making the work easier. This can be done reliably and easily.

In the duster manufacturing method of the present invention, in addition to the above-mentioned effects, the stitch holding thread is formed by chain stitching, so the stitch can be removed by simply pulling the thread from one side, and the stitch selvage is spirally shaped against the handle. The chain stitch can be easily removed when the chain stitch is rolled down.
