Capturing mechanism with a flexible tongue having guidetabs comprising hooks
View Patent ↗A flexible tongue having guide tabs is used in a battery capturing mechanism to engage alignment grooves formed in a battery cartridge. The guide tabs form hooks so that when the battery has been inserted, thereby causing the tongues to deflect at a flexible hinge as the battery slides into the capturing mechanism, the hooks retain the battery. Preferably tapered guide rails are aligned with the tabs and are formed on a rigid floor to which the tongue's flexible hinge attaches, thereby guiding a connector of the battery into electrical engagement with a corresponding connector that is part of the device into which the battery capturing mechanism is used. To remove the battery, the tongue may be depressed and battery grips grasped to retrieve the battery from the mechanism.
1. A mechanism for capturing and interfacing an external component into a cavity in a device housing comprising:
a floor extending between a receiving end and an interface end of the cavity;
guide rails defined in the floor;
a flexible tongue defined in the floor and attached to the floor proximate an interface end, the interface end being at the extent of the cavity proximate a coupling for interfacing the component to the device;
guide tabs defined in the tongue having respective centerlines aligned with the guide rails; and
capturing hooks defined in the guide tabs such that when the component is coupled at the interface said hooks positively retain the component into the device.
2. The mechanism of claim 1 wherein the guide rails are tapered such that the thickness of the guide rails is greater near the interface end of the cavity than at the receiving end.
3. The mechanism of claim 1 further comprising a compartment door that covers an opening at the receiving end of the cavity, the door engaging a battery grip thereby assisting the capturing hooks in retaining the battery in mechanism.
4. The door of claim 3 wherein said door is secured to the device housing with a press-fit snap.
5. The mechanism of claim 1 wherein the component is a battery cartridge.
6. A device having a mechanism for capturing and interfacing an external component into a cavity within a housing of the device wherein the mechanism comprises:
a floor extending between a receiving end and an interface end of the cavity;
guide rails defined in the floor;
a flexible tongue defined in the floor and attached to the floor proximate an interface end, the interface end being at the extent of the cavity proximate a coupling for interfacing the component to the device;
guide tabs defined in the tongue having respective centerlines aligned with the guide rails; and
capturing hooks defined in the guide tabs such that when the component is coupled at the interface said hooks positively retain the component into the device.
7. The mechanism of claim 6 wherein the guide rails are tapered such that the thickness of the guide rails is greater near the interface end of the cavity than at the receiving end.
8. The mechanism of claim 6 further comprising a compartment door that covers an opening at the receiving end of the cavity, the door engaging a battery grip thereby assisting the capturing hooks in retaining the battery in mechanism.
9. The door of claim 8 wherein said door is secured to the device housing with a press-fit snap.
10. The mechanism of claim 6 wherein the component is a battery cartridge.
