Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a bag to be worn by a person, more particularly to a bag that is capable of illumination.

2. Description of the Related Art

For safety purposes, a wearable bag is usually sewn with light-reflecting sheet elements on its surfaces for providing a light signal by reflecting the light incident from an external light source.

However, as these light-reflecting sheet elements can reflect light only when there is an incident light, they are ineffective in case of lack of a light source.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 3, the preferred embodiment of a wearable article according to the present invention, such as a bag 10 adapted to be worn by a person, is shown to include a bag body 1, a flexible transparent tube 2, and a lamp device 3.

The bag body 1, which is in the form of a backpack in this embodiment, includes flexible first and second outer sheets 11, 12 disposed adjacent to each other.

The transparent tube 2 has a tube body 21 with an outer surface 210, and a connecting flange 22 extending outwardly and radially from the outer surface 210 of the tube body 21, and clamped and fixed between sides 111, 121 of the first and second outer sheets 11, 12 such that the tube body 21 is disposed at a junction of the first and second outer sheets 11, 12. In this embodiment, the transparent tube 2 is made of one of polyvinyl chloride (PVC) and thermoplastic polyurethane (TPU), and has a color similar to that of the bag body 1.

Referring further to FIG. 4, the lamp device 3 includes a wire unit, a lamp unit, a casing 31, a power source 30, and a power switch 32.

The wire unit is disposed in and extends outwardly of the tube body 21 of the transparent tube 2, and includes first and second conducting wires 33, 34 isolated electrically from each other. Preferably, each of the first and second conducting wires 33, 34 is an enamel-insulated wire.

The lamp unit is disposed sealingly in the tube body 21 of the transparent body 2, and includes a plurality of LED chips 35. Each LED chip 35 has an anode terminal 351 connected electrically to the first conducting wire 33 via a mounting seat 36 (see FIG. 2), and a cathode terminal 352 connected electrically to the second conducting wire 34 such that the LED chips 35 are coupled in parallel through the wire unit (see FIG. 4).

The power source 30, which is a battery in this embodiment, is disposed sealingly in the casing 31, and is coupled to the lamp unit through the wire unit for supplying electric power to the lamp unit.

The power switch 32 is mounted on the casing 31, and is coupled between the power source 30 and the lamp unit (see FIG. 4). The power switch 32 is operable so as to control supply of the electric power from the power source 30 to the lamp unit through the wire unit

In sum, due to the presence of the lamp device 3, the wearable bag 10 of the present invention is capable of illumination, thereby actively producing a warning light signal for safety purposes. Furthermore, when illuminating, the bag 10 has an attractive appearance.

While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
