INTEGRAL STRUCTURE OF COTTON YARN STRIPS AND A CIRCULAR FRAME BODY OF A MOP
An integral structure of cotton yarn strips and a circular frame body of a mop, comprising: a circular frame body having a through hole at the center thereof; and a plurality of cotton yarn strips positioned at the bottom of the circular frame body. The top portions of the cotton yarn strips are radially arranged in a ∩-shaped way within a mold assembly of the circular frame body such that the top portions of the cotton yarn strips and the circular frame body are integrally formed. The circular frame body includes a circumferential rib at the center of each of the radial ∩-shaped parts of the cotton yarn strips such that the circumferential ribs are hidden against the ∩-shaped top portions of the cotton yarn strips to allow a tight fit of the top portions of the cotton yarn strips in the circular frame body.

1. Field of the Invention
The invention relates to an integral structure of cotton yarn strips and a circular frame body of a mop, and more particularly to a structure that permits a rapid formation of the circular frame body and a reliable fastening of the cotton yarn strips.
2. Description of the Related Art
In the daily life, the mop is an indispensable cleaning tool. The mop includes a plurality of cotton yarn strips fastened at a mop head for absorbing the impurities and liquid on the floor. As a result, a clean floor may be achieved.
The conventional mop includes a bundle of cotton yarn strips fastened at a circular plastic head. Another conventional mop includes a plurality of the cotton yarn strips properly arranged and fastened at the end of an elongated plastic or wood stick. However, the cleaning effect of the circular plastic head mop or the elongated mop is affected to some extent since the cotton yarn strips are not easy for outspread.
Therefore, a disc type rotating mop head was developed for avoiding the above-mentioned drawbacks. The mop head is rotatable at 360° at the bottom of a handle. The cotton yarn strips are arranged in a circular way at the bottom of a circular frame. This disc type rotating mop head tends to achieve the cleaning effect and enhance the practicalness. However, in producing the disc type rotating mop head, a circular frame 80, as shown in
An object of the invention is to provide an integral structure of cotton yarn strips and a circular frame body of a mop wherein the cotton yarn strips and the circular frame body are integrally formed in a mold assembly, thereby achieving a rapid production. In this way, the production capacity can be enhanced and the production cost can be reduced.
Another object of the invention is to provide an integral structure of cotton yarn strips and a circular frame body of a mop wherein the plastic circular frame body 10 includes circumferential ribs 13 pushing against the top portion of the cotton yarn strips 20 to allow a tight fit such that the cotton yarn strips won't be easily loosened. Moreover, the quality can be improved and the service life can be prolonged.
In order to achieve the above-mentioned objects, an integral structure of cotton yarn strips and a circular frame body of a mop in accordance with the invention includes:
-
- a) a circular frame body having a through hole at the center thereof; and
- b) a plurality of cotton yarn strips positioned at the bottom of the circular frame body;
wherein the top portions of the cotton yarn strips are radially arranged in a ∩-shaped way within a mold assembly of the circular frame body such that the top portions of the cotton yarn strips and the circular frame body are integrally formed; and
wherein the circular frame body includes a circumferential rib at the center of each of the radial ∩-shaped parts of the cotton yarn strips such that the circumferential ribs are hidden against the ∩-shaped top portions of the cotton yarn strips to allow a tight fit of the top portions of the cotton yarn strips in the circular frame body.
The accomplishment of this and other objects of the invention will become apparent from the following descriptions and its accompanying figures of which:
First of all, referring to
As shown in
The invention features that the cotton yarn strips 20 are pushed by an indentation 71 (formed at the top of a tappet 70) into the molding cavity 63 such that the cotton yarn strips 20 are arranged in a ∩-shape in the molding cavity 63 of the circular frame body 10. The structure of the tappet 70 is illustrated in
For information on how to automatically feed the cotton yarn strips 20 into the mold assembly 60 and how to cut them off, refer to the pending patent application of the forming machine filed by the same applicant of the invention. The features of the invention lie in the forming structure instead of the forming machine so that no further descriptions thereto are given hereinafter.
According to the invention, the cotton yarn strips 20 is fastened by the above-mentioned H-shaped parts 15 integrally formed by the injection molding process at the top portions 21 of the cotton yarn strips 20. The bonding force acts on the ∩-shaped parts of the cotton yarn strips 20 in a staggered way. Therefore, the cotton yarn strips 20 are tightly secured and won't be easily loosened
Many changes and modifications in the above-described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
Claims
1. An integral structure of cotton yarn strips and a circular frame body of a mop, comprising:
- a) a circular frame body having a through hole at the center thereof; and
- b) a plurality of cotton yarn strips positioned at the bottom of the circular frame body;
- wherein the top portions of the cotton yarn strips are radially arranged in a ∩-shaped way within a mold assembly of the circular frame body such that the top portions of the cotton yarn strips and the circular frame body are integrally formed; and
- wherein the circular frame body includes a circumferential rib at the center of each of the radial ∩-shaped parts of the cotton yarn strips such that the circumferential ribs are hidden against the ∩-shaped top portions of the cotton yarn strips to allow a tight fit of the top portions of the cotton yarn strips in the circular frame body.
2. The integral structure of cotton yarn strips and a circular frame body of a mop as recited in claim 1 wherein the circumferential rib includes an upright rib portion at both sides thereof, thereby creating an H-shaped positioning part.
