DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
There are a variety of conventional carriers such as handbags, backpacks, suitcases, etc. The primary purpose of the carriers is to store or carry items. It is not uncommon that a user would use a carrier to carry many items including small objects in a carrier. Studies leading to the present invention reveals that searching for a particular item (e.g. small object) from among the many items in the carrier can often be a challenging task. For example, regardless of the ambient light conditions, the interior of the carrier is necessarily darker because the interior is shielded by the body of the carrier. As such, searching for a desired item in a darker condition is necessarily difficult. The situation is made worse when there is minimal or no ambient light. In such circumstances, a user would be unable to look for the desirable item visually, but rather identify the desirable by feeling his/her way through in no the carrier.
Some embodiments of the present invention provides a bag capable of emitting light. The bag comprises a bag main body and a light-emitting system mounted in the bag main body. The main body has an inner lining made of fiber optics. The light-emitting system comprises a power source, a switch and a light source such as a lamp. The inner lining is woven from the fiber optics. The lamp is embedded in the optic fibers. The power source supplies power to the lamp such that it emits light and the emitted light enters the optic fibers such that the optic fibers also emit light. The on or off of the light source is controlled by the switch.
Referring to specific embodiments, an embodiment of the present invention is concerned with a handbag, illustrated schematically in FIG. 3 and generally designated. The handbag comprises a main body 1 with an externally facing portion made of a soft material, an strap acting as a handle with which a user can hold, an upper rim defining an opening via which access to an interior of the handbag can be achieved, an inner lining defining a cavity in the handbag for containing items to be carried, and an illumination system. FIG. 3 shows the handbag in a first configuration in which the opening is collapsed such that access to the interior is denied. FIG. 4 however shows the handbag in a second configuration in which the opening is enlarged allowing access to the interior.
Referring to FIG. 4, the handbag is provided with a locking mechanism 2 for bringing the rim together, thus closing the opening. The locking mechanism 2 includes a first member arranged on one side of the rim and a second member arranged on an opposite side of the rim. In this embodiment, the first and second member are configured to be magnetically attractable together. Thus, when the first and second members are brought together, the opening of the handbag is closed, thus securing storage of items in the handbag during travel.
Still referring to FIG. 4, the inner lining 3 is made of a fabric comprising lighting optical fibers. The illumination system includes a circuitry of a battery E, an electrical switch K, a capacitor C, a light source L, a resistor and the optical fibers. In this embodiment, the electrical switch K and the locking mechanism 2 are made of one integral component such that when the first and second members are disengaged the electrical switch is turned off. The light source is connected, and arranged to feed lighting therefrom, to the optical fibers for illumination of the cavity in the handbag. The resistor is provided to allow adjustment of current passable in the illumination system, thus to adjust the degree of possible illumination in the handbag.
In some embodiments, the bag capable of emitting light further comprises a capacitor C. The switch K is a magnetic switch. The power source E, the capacitor C, the switch K and the lamp L form a capacitor charging and discharging circuit. The illumination system includes a charging circuit as illustrated in FIG. 1 and a discharging circuit as illustrated in FIG. 2. The charging circuit is kicked in when the locking mechanism is set at the locking status, meaning the handbag is closed, and when the electrical switch K is turned to a charging status. In this circuit state, the capacitor C is adapted to be charged up by the battery E to its full capacity. In this circuit state, the light source L is not light up because no electrical current passes the light source.
The discharging circuit is kicked in when the locking mechanism is set at the unlocking status, meaning the handbag is open, and when the electrical switch K is turned to a discharging status. In this circuit state, the capacitor C is adapted to supply stored electrical power to the light source L, until such time when the stored electrical power is depleted.
It is thus envisaged that the charging or discharging of the capacitor C is determined by switching of the switch K, while the switching of the switch K is determined by opening or closing of the bag. The switch K switches the charging circuit on when the bag is closed, and the current flows from the power source E to the capacitor C and ceases when the capacitor C is fully charged, as shown in FIG. 1. During this charging process, the lamp L does not emit light, and the status of the bag when it is closed is shown in FIG. 3. The switch K switches the discharging circuit on when the bag is opened and the current flows from the capacitor C to the lamp L such that it emits light, as shown in FIG. 2. Since in this embodiment the lamp L is embedded in the optic fibers, the light emitted by the lamp L enters the optic fibers and travels therein. In this embodiment, not all the light is reflected because a portion of the light is reflected and guided in the optic fibers, while another portion of the light is refracted and emits out of the optic fibers. As a result, the entire optic fibers also emit light. Because in this embodiment the entire inner lining 3 is formed of the optic fibers, the entire inner lining 3 emits light. Therefore, the inner lining 3 starts emitting light as soon as the bag is opened, making finding items in the bag especially in the dark extremely easier. The status of the bag when it is opened is shown in FIG. 4. In FIG. 4, the reference sign 2 represents the switch K. When the bag is closed again, the switch K switches the charging circuit on and the discharging circuit off, the circuit returns to charging mode, and the lamp L does not emit light any longer.
Since the capacity of the capacitor C is limited, when the capacitor is depleted, the lamp L does not emit light and the inner lining 3 correspondingly does not emit light. Therefore, the capacity limit of the capacitor C serves to limit the duration of light emission of the inner lining 3.
It is envisaged that the light source L may be an LED lamp.
In some embodiments, the capacitor charging and discharging circuit further comprises a current limiting resistor R disposed on the discharging circuit for limiting current of the discharging circuit to protect the lamp L, as shown in FIG. 1 or FIG. 2.
It is envisaged that the handbag may be a handbag, a shoulder bag, or a backpack.
It is thus understandable that the present invention can alleviate the disadvantages associated with conventional bags, including conventional bags with complex electrical systems, systems which have a high demand of electrical power, systems which take up precious space or adds to the weight of the carrier, or systems which can be allow full illumination of cavity in the carrier.
Although the embodiments of the present invention are described above with reference to the drawings and by way of examples, the present invention is not limited to these embodiments which are illustrative only rather than restrictive. Those skilled in the art will be able to make various modifications and/or alterations under teaching of present utility model, without departing from the spirit of the present utility model and the scope of the appended claims, which fall into the protection scope of the present utility model.
