- 2. Description of Related Arts
- A conventional drawer usually comprises a drawer body and a front panel, wherein the drawer body is slidably mounted on a drawer compartment formed on a cabinet so that a user is able to slide the drawer body in and out of the drawer compartment for achieving different purposes.
- Drawers have widely been utilized in a wide variety of circumstances and a number of accessories have been incorporated into conventional drawers in order to fit new situations in which a drawer may be utilized. For example, power unit has been incorporated into conventional drawer so that the user does not need to manually open or close the drawer.
- Despite their long and widespread applications, there exist several deep-seated disadvantages which need to be addressed. First, the most usual way of opening a drawer is by the user's hand. From the view point of many, this may seem inevitable because one nevertheless has to manually open a drawer in order to retrieve or put in something. Yet there exist situations where it is not desirable or convenient for the user's hand to touch the drawer's handle for opening it. For example, when the user is in the middle of doing something in which his/her hands are contacting with, say, dirty materials or raw food (if the drawer in a kitchen), the user may not wish to let his/her hands touching the drawer's handle for opening the drawer, even though in fact the user actually needs to open the drawer for retrieving something which he/she needs at that moment.
- Second, if a drawer is fully loaded so that a considerable amount of force is required to pull the drawer out of the drawer compartment, the user may not have enough power to do so. This problem may not be that severe for drawers used in domestic environment, yet in workplaces such as in the office, a particular cabinet may contain a huge amount of files so that the user may not be able to pull the particular drawers out of the corresponding drawer compartments for retrieving, say, particular files.
- If the drawer is positioned at a very low position, such as the lowest in a cabinet, it is difficult then for a user to effectively exert large amount of force for pulling the drawer out of the drawer compartment.
- Obviously, one may purchase motorized drawers for resolving the above problems, but the main problem is that motorized drawers are usually expensive and as a result may not be affordable for general households. Moreover, even though one may afford to purchase sophisticated drawers, the first problem is still not yet resolved since the relevant users still have to use their hands for operating any control panels or even remote controllers.
- A main object of the present invention is to provide a drawer releasing device for a drawer, wherein the drawer releasing device is capable of releasing the drawer through simple actuation at a distance therefrom in a hand-free manner. In other words, a user of the present invention does not need to physically touch the drawer for pulling it out.
- Another object of the present invention is to provide a drawer releasing device which is capable of automatically releasing a drawer out of the drawer compartment upon a simple actuation of an actuation unit extended out of the drawer by the user of the present invention. In other words, when the drawer is fully loaded, the user does not need to exert large amount of force for trying to pull put the drawer from the drawer compartment.
- Another object of the present invention is to provide a drawer releasing device which is adjustable in its orientation and easy to assemble and disassemble so as to fit a wide variety of drawer compartment in order to facilitate widespread application of the present invention.
- Another object of the present invention is to provide a drawer releasing device which can be adopted to use in conjunction with a wide variety of containers for fitting a wide variety of different circumstances. For example, a slider platform may be adapted to support rubbish bins or a basket for normally receiving the rubbish bin or the basket into a drawer compartment while automatically releasing the rubbish bin to be extended for convenient access by the user of the present invention.
- Another object of the present invention is to provide a drawer releasing device which does not involve electrical components and even complicated mechanical component, so that the manufacturing cost and the ultimate selling price of the present invention can be kept to minimum.
- Accordingly, in order to accomplish the above objects, the present invention provides a drawer releasing device for a cabinet having a drawer compartment, wherein the drawer releasing device comprises:
- a docking frame, which is adapted for supporting within the drawer compartment of the drawer, comprising a mounting base and a slider platform slidably and inclinedly mounted on the mounting base to slide between a slide-in storage position that the slider platform is disposed within the drawer compartment and a slide-out accessing position that the slider platform is slid out of the drawer compartment, wherein the mounting base is normally retained at the slide-in storage position; and
- an actuation unit which comprises a hand-free actuator positioned out of the drawer compartment and an actuating cable which is extended from the docking frame to the actuator and is arranged in such a manner that when the actuator is operated for providing an initial momentum of the slider platform, the slider platform is automatically sliding out of the drawer compartment in a hand-free manner.
