Abstract

A portable carrier module having a safety interconnect latch mechanism for securing the portable carrier module to a portable product. The portable carrier has a rail on one of its outer walls for engaging with a track on the portable product and for aligning the portable product to the portable carrier.

Claims

1. A portable carrier for receiving a portable product having a recess forming a notch extending from an edge of the recess, the portable product further having a track on one of a plurality of external surfaces, the portable carrier comprising:

(a) a housing having a plurality of outer walls;

(b) a rail on one of the plurality of outer walls for engaging the track on the portable product and for aligning the portable product to the portable carrier;

(c) a latch assembly for insertion into the recess in the portable product, comprising;

(1) a shoulder portion adapted to fit into the recess of the portable product;

(2) a locking lip portion extending from the shoulder for engaging the notch of the portable product;

(3) a flexible member portion connected at one end to the shoulder and secured at another end to one of the plurality of outer walls and that allows the locking lip to move from a first position external to the recess to an intermediate position within the recess;

wherein when (A) the rail on one of the plurality of outer walls engages the track on the portable product so as to align the portable product to the portable carrier and (B) the locking lip is in the intermediate position within the recess and (C) the portable carrier is elevated relative to the portable product, the locking lip is caused to move to a locked position within the recess where the locking lip and notch are lockingly engaged to lock the portable carrier to the portable product.

2. The portable carrier as in claim 1 wherein the latch assembly is a one piece member made of a flexible plastic.

3. The portable carrier as in claim 2 wherein the one of the plurality of outer walls to which the flexible member is secured is the one of the plurality of outer walls upon which the rail is positioned.

4. The portable carrier as in claim 3 wherein the latch mechanism further includes means for releasing the latch assembly from within the recess.

5. The portable carrier as in claim 4 wherein the means for releasing is a neck member connected to the shoulder for moving the locking lip from said intermediate position within the recess of the portable product to said first position external to the recess of the portable product.

6. The portable carrier as in claim 5 wherein said portable carrier contains an electric power source.

7. The portable carrier as in claim 6 further including an electrical connector for the transfer of power from the electrical power source to the portable product.

8. The portable carrier as in claim 7 wherein the electrical connector is the rail.

9. The portable carrier as in claim 1 wherein the portable carrier receives and stores monitoring data transferred from the portable product.

10. The portable carrier as in claim 1 wherein the flexible member portion is at least two flexible member portions and further includes two legs each of which is connected at one end to a corresponding one of the at least two flexible member portions and secured at another end to one of the plurality of outer walls.

11. The portable carrier as in claim 10 wherein the latch assembly is a one piece member made of a flexible plastic.

12. The portable carrier as in claim 11 wherein the one of the plurality of outer walls to which the legs are secured is the one of the plurality of outer walls upon which the rail is positioned.

13. The portable carrier as in claim 12 wherein the latch mechanism further includes means for releasing the latch assembly from within the recess.

14. The portable carrier as in claim 13 wherein the means for releasing is a neck member connected to the shoulder for moving the locking lip from said intermediate position within the recess of the portable product to said first position external to the recess of the portable product.

15. The portable carrier as in claim 14 wherein said carrier product contains an electric power source.

16. The portable carrier as in claim 15 further including an electrical connector for the transfer of power from the electrical power source to the portable product.

17. The portable carrier as in claim 16 wherein the electrical connector is the rail.

18. The portable carrier as in claim 10 wherein the portable carrier receives and stores monitoring data transferred from the portable product.
