Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates, in general, to a roller for arranging a webbing, and more particularly, to a webbing roller which allows a portion of the webbing of a bag, a knapsack, a baby carrier, etc., drooping after a user adjusts the effective length of the webbing to fit his or her body, to be tidily arranged.

2. Description of the Related Art

In general, webbings are used in bags, knapsacks, baby carriers, etc. for ensuring convenience in use.

A webbing means a woven material having a certain width. In detail, the webbing indicates the material which is frequently used through our lives for the seat belt of a vehicle, the chin strap of a safety helmet, a collar for a dog, clothes, a bag, a knapsack, etc.

The webbing can be integrally attached to a bag, a knapsack, etc. to have a fixed length or can be used along with an adjuster such as a buckle member to be freely adjusted in the effective length thereof depending upon the physical constitution of a user.

That is to say, when a user carries a bag or a knapsack on the shoulder or by the hand, if the user feels that the effective length of a webbing is too long so it is inconvenient to carry the bag or knapsack, the effective length of the webbing can be adjusted by manipulating the buckle member.

However, in this case, referring to FIG. 1, as remaining portions of webbings 10 droop with substantial lengths, the outer appearances thereof deteriorate, and it is difficult to arrange the remaining portions of the webbings 10. Also, when the effective length of the webbing 10 is adjusted using the buckle member, the effective length of the webbing 10 is likely to abruptly increase or decrease by inadvertent touch to the webbing 10.

In order to cope with this problem, in the conventional art, Velcro brand hook and loop fastener strips are stitched to the webbings 10 so that the webbings 10 can be tidily arranged using the Velcro brand hook and loop fastener strips with the drooping portions of the webbing 10 rolled up. Nevertheless, even in this case, when the webbings 10 are used for an extended period, the corners of the Velcro brand hook and loop fastener strips are likely to be worn out so that the outer appearances of the webbings 10 deteriorate, and the adhesion force of the Velcro brand hook and loop fastener strips is likely to decrease with the lapse of time. Also, as the Velcro brand hook and loop fastener strips adhere to clothes, the clothes are likely to be damaged.

As a result, in the conventional art, when the effective length of a webbing is adjusted using a buckle member, a remaining portion of the webbing droops, whereby the outer appearance of the webbing can deteriorate. Also, since it is difficult to appropriately arrange the remaining portion of the webbing, the effective length of the webbing is likely to abruptly increase or decrease by inadvertent touch to the webbing.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made in an effort to solve the problems occurring in the related art, and an object of the present invention is to provide a webbing roller which allows a portion of a webbing, drooping after adjusting the effective length of the webbing, to be tidily arranged so that the outer appearance of a user's body, a bag, a knapsack, etc. can be improved.

In order to achieve the above object, according to the present invention, there is provided a webbing roller suitable for being coupled to a portion of a webbing, drooping after an effective length of the webbing is adjusted, the webbing roller comprising a pair of webbing roller bodies; an opening defined at first ends of the webbing roller bodies and having a retainer band which is connected to the first ends of the webbing roller bodies around the opening; and a fastening projection formed on second ends of the webbing roller bodies to allow the retainer band to be fastened thereto.

Among these drawings, FIG. 2 is a perspective view illustrating the entire construction of a webbing roller 100 in accordance with an embodiment of the present invention, which is suitable for being coupled to a portion of a webbing, which becomes useless and droops after the effective length of the webbing is adjusted, FIG. 3 is a perspective view illustrating a state in which a retainer band 200 is coupled to the webbing roller 100 according to the present invention.

Referring to FIGS. 2 and 3, the webbing roller 100 in accordance with the embodiment of the present invention, which is to be coupled to a webbing, includes a pair of webbing roller bodies 190 which are formed parallel to each other at the center portion of the webbing roller 100, a first wing 150 which is formed on the first ends of the webbing roller bodies 190 and is defined with an opening 110 around which a retainer band 200 is to be connected, and a second wing 170 which is formed on the second ends of the webbing roller bodies 190 and is formed with a fastening projection 120 to which the retainer band 200 is to be fastened.

A slit 130 is defined between the pair of webbing roller bodies 190. An end of the webbing can be passed through the slit 130 and can be coupled to any one of the webbing roller bodies 190 through stitching. Depressions and prominences can be formed on the webbing roller bodies 190 so as to prevent the webbing from slipping on the webbing roller bodies 190.

The first wing 150 and the second wing 170 are formed parallel to each other. The pair of webbing roller bodies 190 are formed to be placed at positions which are separated by a predetermined distance from both ends of the first wing 150 and the second wing 170 formed parallel to each other. As a consequence, with the end of a portion of the webbing, which becomes useless and droops after the effective length of the webbing is adjusted, passed through the slit 130 and coupled to any one of the webbing roller bodies 190 through stitching, the useless portion of the webbing can be wound around the webbing roller bodies 190 by rotating the webbing roller 100. The first wing 150 and the second wing 170, which are formed parallel to each other, perform a guiding function in the widthwise direction of the webbing so that the webbing can be evenly wound around the webbing roller bodies 190.

The first wing 150 is defined with the opening 110 around which the retainer band 200 is connected. At least one opening 110 can be defined to have a circular or elliptical sectional shape.

The opening 110 of the first wing 150 is defined outside the middle portion of the first wing 150 so that the retainer band 200 can be connected to the first wing 150 around the opening 110. First protrusions 140 are formed on the middle portion of the first wing 150 in such a way as to protrude sideward between the first ends of the pair of webbing roller bodies 190.

The fastening projection 120 is formed on the middle portion of the second wing 170. The fastening projection 120 is formed to project outward from the middle portion of the second wing 170 so that the retainer band 200 connected to the first wing 150 around the opening 110 can be fastened to the fastening projection 120. By crossing the retainer band 200 over the useless portion of the webbing which is wound around the pair of webbing roller bodies 190 and then fastening the retainer band 200 to the fastening projection 120, the useless portion of the webbing can be held wound on the webbing roller 100.

The fastening projection 120 is formed to have a neck part 180 which has a reduced thickness so as to allow the retainer band 200 to be reliably kept fastened to the fastening projection 120. Preferably, the fastening projection 120 is formed to have the substantial shape of a mushroom such that one portion thereof to hold the retainer band 200 becomes concave and the other portion thereof not to hold the retainer band 200 has a larger width so as to prevent the unintentional release of the retainer band 200.

Second protrusions 160 are formed on the middle portion of the second wing 170 in such a way as to protrude sideward between the second ends of the pair of webbing roller bodies 190.

The first protrusions 140 and the second protrusions 160 are formed to have a height that is greater than the thickness of the useless portion of the webbing wound around the pair of webbing roller bodies 190 so that the webbing can be evenly wound in the vertical direction when the useless portion of the webbing is wound around the pair of webbing roller bodies 190 by rotating the webbing roller 100 after the end of the webbing is passed through the slit 130 and coupled to any one of the webbing roller bodies 190 through stitching.

Also, a fixing holder can be additionally formed around the fastening projection 120 so as to prevent the retainer band 200 from being released. The fixing holder can be formed integrally with the webbing roller 100 and can function to prevent the retainer band 200 from being released from the fastening projection 120 after the retainer band 200 is fastened to the fastening projection 120.

Referring to FIG. 3, the retainer band 200 is connected to the first end of the webbing roller 100 which defines the opening 110. A procedure for connecting the retainer band 200 to the first wing 150 of the webbing roller 100 around the opening 110 is as described below. The first end of the retainer band 200 is inserted through the opening 110 of the webbing roller 100. When the first end of the retainer band 200 is inserted half, the second end of the retainer band 200 is inserted through the first end of the retainer band 200. Then, by pulling the second end of the retainer band 200, the first end of the retainer band 200 is connected to the first wing 150 of the webbing roller 100 which defines the opening 110. It is preferred that the retainer band 200 be made of an elastic material having a certain degree of contractibility.

In the webbing roller 100, the first protrusions 140 formed on the first wing 150 and the second protrusions 160 formed on the second wing 170 function to guide the webbing to be evenly wound in the vertical direction when winding the webbing around the pair of webbing roller bodies 190.

FIG. 4 is a plan view illustrating the webbing roller 100 according to the present invention. It is ideal for maintaining the elasticity of the retainer band 200 that the first protrusions 140, which are formed adjacent to the opening 110, have a height 400 of 1.5˜2.5 mm, preferably, 1.7˜1.8 mm when measured from the outer surfaces of the webbing roller bodies 190. The second protrusions 160 are formed to have the same height as the first protrusions 140 when measured from the outer surfaces of the webbing roller bodies 190.

FIG. 5 is a view illustrating a state in which a portion of a webbing, drooping after the effective length of the webbing is adjusted, is coupled to the webbing roller 100 according to the present invention.

A procedure for coupling the useless portion of a webbing 500 to the webbing roller 100 through the slit 130 is as described below. After the end of the webbing 500 is inserted through the slit 130, a predetermined length of the webbing 500 is pulled out in a direction opposite to the insertion direction, and the end of the webbing 500 is stitched to a part of the webbing 500 so that the webbing 500 is firmly coupled to any one of the webbing roller bodies 190 and then the useless portion of the webbing can be wound around the webbing roller bodies 190.

FIG. 6 is a view illustrating a state in which the webbing is arranged by means of the webbing roller 100 according to the present invention.

With the remaining drooping portion of the webbing coupled to the webbing roller bodies 190 through the slit 130, the remaining drooping portion of the webbing is wound on the webbing roller 100 by rotating the webbing roller 100. After the webbing is wound on the webbing roller 110, the webbing is fixedly retained by fastening the second end of the retainer band 200, which has the first end thereof connected to the webbing roller 100 around the opening 110, to the fastening projection 120.

FIG. 7 is a view illustrating an exemplary application of the webbing roller 100 according to the present invention to a knapsack. A remaining portion of a webbing, which becomes useless and droops after the effective length of the webbing is adjusted in a knapsack, is tidily arranged using the webbing roller 100 (see the reference numeral 700). As a consequence, it is possible to prevent the drooping portion of the webbing deteriorates the outer appearance of the webbing. Also, due to the presence of the webbing roller 100 according to the present invention, it is possible to solve the problem which is caused in the conventional art by the fact that the effective length of the webbing is likely to abruptly increase or decrease by inadvertent touch to the webbing when the effective length of the webbing is adjusted with the knapsack carried on the shoulder.

As is apparent from the above description, the webbing roller according to the present invention provides advantages in that, since a portion of a webbing, drooping after the effective length of the webbing is adjusted, can be tidily arranged, it is possible to prevent the outer appearance of the webbing from deteriorating.

Also, when the effective length of the webbing is adjusted using a buckle member or the like, it is possible to prevent the adjusted state of the webbing from being spoiled due to unintentional increase or decrease in the effective length of the webbing by inadvertent touch to the webbing.

Although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and the spirit of the invention as disclosed in the accompanying claims.
