Problems solved by technology

The aforementioned conventional spool assembly 100 is disadvantageous in that, when the flexible sheet-like material 3 is wound on the tubular hub body 1, the securing end 31 of the flexible sheet-like material 3 bulges out from the exposed surface 21 of the double-sided adhesive tape member 2.
As shown in FIG. 4, this results in undesirable wrinkles (or is creases) 30 being formed along portions of the flexible sheet-like material 3.
This renders these portions of the flexible sheet-like material 3 defective and unfit for selling.

Embodiment Construction

[0019]Referring to FIG. 5, the preferred embodiment of a spool assembly 4 for winding a flexible sheet-like material 7 thereon according to this invention is shown to include a tubular hub body 6 and a securing member 5.

[0020]The flexible sheet-like material 7 may be, for example, a fabric or an automobile tinted window film, and has a uniform thickness.

[0021]The tubular hub body 6 surrounds an axis (I), and has inner and outer surfaces 61, 62. The outer surface 62 of the tubular hub body 6 is formed with an axially extending groove 60 that is defined by a groove-defining wall 63. The groove-defining wall 63 of the tubular hub body 6 has opposite first and second wall portions 631, 632, and an intermediate wall portion 633 that interconnects the first and second wall portions 631, 632 thereof. In this embodiment, the second wall portion 632 is higher than the first wall portion 631 with respect to the intermediate wall portion 633.

[0022]With further reference to FIG. 6, the securing...

Abstract

A spool assembly for winding of a sheet-like material thereon includes a tubular hub body and a securing member. The tubular hub body is formed with a groove, and has a radial cross-section that has grooved and non-grooved segments. The non-groove segment extends from the grooved segment, and has opposite first and second ends, and a radial thickness that increases gradually from the first end to the second end thereof. The securing member is mounted in the groove in the tubular hub body for securing a securing end of the flexible sheet-like material to the tubular hub body.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a spool assembly, more particularly to a spool assembly on which a flexible sheet-like material can be wound smoothly and evenly.[0003]2. Description of the Related Art[0004]FIG. 1 illustrates a conventional spool assembly 100 that includes a tubular hub body 1 and a double-sided adhesive tape member 2.[0005]The tubular hub body 1 surrounds an axis (A), and has inner and outer surfaces 11, 12. The outer surface 12 of the tubular hub body 1 is formed with an axially extending groove 10 that is defined by a groove-defining wall 13.[0006]With further reference to FIG. 2, the double-sided adhesive tape member 2 is disposed in the axially extending groove 10 in the outer surface 12 of the tubular hub body 1, is attached adhesively to the groove-defining wall 13, and has an exposed surface 21 that is flush with the outer surface 12 of the tubular hub body 1. A flexible sheet-like material 3 is tightl...
