Abstract

A credit card holder composed of a series of transparent pockets is provided with an alarm system warning the owner that a card was not returned into its pocket. Each pocket is provided with two electric contact strips attached to the inside of the pocket walls which are separated by the credit card inside the pocket and are in contact whenever the card is withdrawn. The card holder contains a battery, a buzzer and a timer suitably connected to the contact strips. This timer serves to delay energizing of the buzzer for a time period in which the transaction can be reasonably accomplished, and sounds the alarm only then.

Claims

1. An alarm system for a cardholder comprising a series of flat, rectangular pockets, each pocket being composed of two adjoining walls, said two walls being interconnected along three sides, while the fourth side is open to permit insertion of a card, two flat contact bodies respectively attached to the inside of each of said pocket walls in opposed alignment, one of said bodies being a permanent magnet and the other of said bodies being made of a magnetic material, said contact bodies being normally separated by an inserted card in each pocket, each of said contact bodies being electrically connected to an indicator circuit means located in a portion of said cardholder, said indicator circuit means being electrically triggered to emit an audible or visual signal upon contact being established between said contact bodies in one pocket, at a predesignated time interval from the moment a card is extracted from said pocket.

2. The alarm system of claim 1, wherein said indicator circuit means comprises an electric cell, a timer, a starter adapted to trigger and to reset said timer, and an indicator, said timer being set to said predesignated time interval.

3. The alarm system of claim 1, wherein said contact bodies are in the shape of flat metal discs.

4. The alarm system of claim 1, wherein said contact bodies are in the form of a metal layer printed on the inside of said walls of said pockets.

5. The alarm system of claim 4, wherein the walls of each of said pockets are urged together by means of leafsprings positioned in said walls.

6. An alarm system for a cardholder comprising a series of flat, rectangular pockets arranged in a single, substantially rectangular strip having opposite ends, each pocket being composed of two adjoining walls, said two walls being interconnected along three sides, while the fourth is open to permit insertion of a card and lies on an edge of said strip extending between said opposite ends, two longitudinal flat conductors spaced from each other and attached to the inside of a first of said two adjoining pocket walls and extending continuously between said opposite ends along substantially the entire strip formed by said pockets between said opposite ends, a third flat conductor attached to the second of said two adjoining walls in each of said pockets so as to overlap both of said two longitudinal conductors, said two adjoining pocket walls in a given pocket corresponding to any one of said pockets being adapted to be normally separated by a card inserted into the given pocket to prevent the third flat conductor from contacting the two longitudinal conductors yet having the two adjoining walls movable toward each other upon the card being withdrawn from said given pocket to have the third flat conductor contact the two longitudinal conductors and span the space therebetween, said two longitudinal conductors being electrically connected to an indicator circuit means located in a portion of said cardholder, said indicator circuit means being electrically triggered to emit an audible or visual signal upon contact being established between the third flat conductor and said two longitudinal conductors at a predesignated time interval from the moment a card is extracted from a pocket.

7. The alarm system of claim 6, wherein said two longitudinal flat conductors are parallel to each other and said third flat conductor is aligned perpendicularly thereto.

8. The alarm system of claim 6, wherein said indicator circuit means comprises an electric cell, a timer, a starter adapted to trigger and to reset said timer, and an indicator, said timer being set to said predesignated time interval.

9. The alarm system of claim 6, wherein the walls of each of said pockets are urged together by means of leafsprings positioned in said walls.

10. An alarm system for a cardholder comprising a series of flat, rectangular pockets arranged in a single substantially rectangular strip having opposite ends, each pocket being composed of two adjoining walls, said two walls being interconnected along three sides, while the fourth side is open to permit insertion of a card and lies on an edge of said strip extending between said opposite ends, a first flat longitudinal conductor attached to the inside of one of said two adjoining pocket walls and extending continuously between said opposite ends along substantially the entire strip formed by said pockets, a second flat longitudinal conductor attached to the inside of the other of said two adjoining pocket walls and extending continuously between said opposite ends along substantially the entire strip formed by said pockets, said first and second longitudinal conductors being aligned so as to overlap in at least one point in each pocket, said two adjoining pocket walls in a given pocket which corresponds to any one of said pockets being adapted to be normally separated by a card inserted into said given pocket to prevent the first and second flat longitudinal conductors from contacting each other yet having the two adjoining walls movable toward each other when said card has been extracted from said given pocket to have the first and second flat longitudinal conductors contact each other in at least one point in said given pocket, each conductor being electrically connected to an indicator circuit means located in a portion of said cardholder, said indicator circuit means being electrically triggered to emit an audible or a visual signal upon contact being established between said firs and second flat longitudinal conductors in said given pocket at a predesignated time interval from the moment a card has been extracted from said given pocket.

11. The alarm system of claim 10, wherein at least one of said first and second conductors is angled in a given direction so as to be non-parallel relative to said fourth side.

12. The alarm system of claim 11, wherein both of the first and second conductors are non-parallel relative to said fourth side, are angled in opposite directions relative to each other, and are positioned so as to overlap at only one point in each of said pockets.

13. The alarm system of claim 12, wherein each of said first and second conductors includes one portion in one of said pockets and a second portion in a pocket adjacent to said one pocket, said first and second portions being connected at the side common to the one pocket and its adjacent pocket, and said first and second portions being angled in opposite directions relative to each other.

14. The alarm system of claim 10, wherein said indicator circuit means comprises an electric cell, a timer, a starter adapted to trigger and to reset said timer, and an indicator, said timer being set to said predesignated time interval.

15. The alarm system of claim 10, wherein the walls of each of said pockets are urged together by means of leafsprings positioned in said walls.
