BACKGROUND OF THE INVENTION
This invention relates generally to the field of lockable containers and more specifically to an insulated programmable lock box primarily for use for food delivery services.
Food delivery from restaurants to customers in their homes or offices has become very popular.
Basically, the restaurant puts the food in an insulated enclosure and has a food delivery person transport the enclosure to the recipient, at which time the recipient removes the food from the enclosure and takes it into their home or office.
However, there have been reported cases of food delivery people gaining access to the insulated enclosure and partaking of the food inside before making the delivery to the end customer. This situation is unacceptable both for the reason of the theft of food and for the possibility of having the food become contaminated by the delivery person's fingers.
BRIEF SUMMARY OF THE INSTANT INVENTION
The primary object of the invention is to provide a lockable box or enclosure whose lock can be programmed with a custom number sequence which an end user needs to know in order to open the box.
Another object of the invention is to provide a programmable lock box that is insulated and used for food delivery from restaurants to individuals at their homes or offices thereby preventing the delivery person from having access to the contents of the box.
Another object of the invention is to provide a programmable lock box that allows a restaurant to send a numerical text to the recipient of the boxed food to so that the recipient can enter the numerical code to open the box.
A further object of the invention is to provide a programmable lock box that allows the recipient of the boxed food to place their smart phone near the box hand have the phone send an audio signal that will unlock the box so that the recipient does not have to physically touch the keypad of the lock.
Other objects and advantages of the present invention will become apparent from the following descriptions, taken in connection with the accompanying drawings, wherein, by way of illustration and example, an embodiment of the present invention is disclosed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.
Referring now to FIG. 1 we see a perspective view of the invention 100. An insulated enclosure box 2 includes a zippered 6 lid 4. The zipper pull 14 is restricted from being pulled by a U shaped locking finger 12. A number code receiving device 8 is installed in a holster 10. The rigid holster 10 includes a rigid flange 16 that reinforces the apertures that retain the U-shaped locking finger 12. Therefore, the enclosure 2 can be made of sewn material such as ballistic nylon and yet the flange area 16 of the U-shaped locking finger 12 hardens the connection point between the U-shaped locking finger 12 and the enclosure 2. In the instance of food delivery, a person at the restaurant sending the food uses a custom electronic software program to generate a unique sequence of numbers in a microprocessor located within the number code receiving device 8 housing. A delivery person then transports the enclosure 2 to a recipient at a home or office. The restaurant person texts a unique sequence of numbers to the recipient's smart phone. The recipient can then press the keypad numbers 9 in the sequence shown in the text message to cause the U-shaped locking finger to slide out, thereby gaining access to the zipper pull 14. In this way, only the recipient, and not the food delivery person, has access to the food being stored within the enclosure 2.
FIG. 2 shows the right side of the holster 10 where an aperture 22 in the holster 10 allows the reception of an audible tone to enter grill 20 of code receiving unit 8. The audible tone is an optional way to cause the lock to open as will be discussed below. The code receiving device 8 includes a keypad 9 and a numerical display 18. The upper portion of the number code receiving device numerical display 18 confirms the numbers that the recipient has selected. Another way that the recipient can activate the lock is to place his or her smart phone near the enclosure and to press an audio option within the text message which then generates tones associated with each number. A microphone 42 within the number code receiving housing hears the tones and unlocks the U-shaped locking finger 12 when the correct sequence of tones is heard.
FIG. 3 shows the code receiving unit 8 being removed from the holster 10. An electrical connection point 200 can be seen which interacts with a mating connector 38 on the underside of the code receiving unit 8. This connection provides the electrical conduit for sending a signal from the code receiving unit 8 to an electro-mechanical assembly 26 located within the enclosure 2 that causes the U-shaped locking finger 12 to slide in or out to lock or unlock the zipper pull of the lid of the enclosure 2.
FIG. 4 shows the number code receiving device sitting in holster 10 with the U-shaped locking finger 12 in the locked position.
FIG. 5 shows the U-shaped locking finger in the unlocked position, allowing free access to zipper pull 14 because the U-shaped locking finger 12 has exited zipper pull aperture 13.
FIG. 6 shows the housing 26 of the electro-mechanical lock assembly. The housing 26 includes a flange 24 that is parallel to and in close proximity to holster flange 16. The side wall of the enclosure 2 is trapped between the rear wall of holster 10 and the front wall of housing 26 as shown in FIG. 13. Cable 28 acts as a conduit between the microprocessor 34 within the code receiving housing 8 as shown in FIG. 10.
FIG. 7 shows the housing cover 26 removed exposing electro-mechanical linear translation device 30.
FIG. 8 shows a front view of the linear translation device 30 whose shaft 31 is fixedly attached to the U-shaped locking finger 12.
FIG. 9 shows the U-shaped locking finger 12 in the open position as shaft 31 has forced it open.
FIG. 10 shows the number code receiving housing 8 with the rear panel removed exposing rechargeable battery 32, microprocessor 34, microphone 42, battery charging port 40, cable receptacle 38 and short-range receiver 36.
FIGS. 11 and 12 shows the electro-mechanical assembly 26 about to be attached to the rear of holster 10 via screws that enter apertures 48. Note that apertures 48, 50 are shown in the side wall of enclosure 2 which correspond to the apertures 48A and 50A shown flange 16 in FIG. 11.
FIG. 13 shows the electro-mechanical housing 26 in place on the inside wall of enclosure 2 and U-shaped locking finger 12 in the locked position as it penetrates apertures 48A and 50A.
FIG. 14 shows a plurality of number code receiving devices 8 installed within charger base 52.
FIG. 15 shows one number code receiving device 8 removed exposing the connection point 54 between the receiving device 8 and the charging circuit located within the charging station housing 52. This connection 54 also acts as a conduit for sending a unique numerical code to the number code receiving device 8. Each time the receiving device 8 is inserted into the charger base 52, a new code is generated. The new code is then sent to the recipient of the enclosure 2.
It should be noted that the above described lockable enclosure can be used for purposes other than food delivery where an item needs to be delivered and the person sending the item wants to make sure that the person doing the delivering cannot gain access to the item, and that only the authorized recipient can gain access to the contents of the enclosure.
While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
