Holder device and system for attachment to mobility equipment

1. A holder device for attachment to a wheelchair or other mobility equipment, the device comprising:

a surface at least partially bounded, the bounded portion defining a slot having an elongated opening opposite the surface;

a first holder magnet at the surface adjacent a terminus of the slot; and

a second holder magnet at the surface spaced apart from the first magnet.

2. The holder device of claim 1 , wherein the surface is only partially bounded, and wherein the first holder magnet is in the slot and the second holder magnet is outside the slot.

3. The holder device of claim 1 , wherein both the first and second holder magnets are within the bounded portion of the holder device surface.

4. A system for fixing an accessory to mobility equipment comprising:

a holder device for attachment to a wheelchair or other mobility equipment, the device comprising:

a holder surface at least partially bounded, the bounded portion defining a slot

a first holder magnet at the surface adjacent a terminus of the slot;

a second holder magnet at the surface spaced apart from the first holder magnet; and

a sliding member for interfacing with the holder device, the sliding member comprising:

a sliding surface for mating with the holder surface;

a first sliding magnet at the sliding surface of the sliding member; and

a second sliding magnet spaced apart from the first sliding magnet,

wherein a distance between the first sliding magnet and the second sliding magnet is substantially similar to a distance between the first holder magnet and the second holder magnet.

5. The system of claim 4 , wherein when the sliding member is fully inserted into the slot, the first holder magnet is opposite the first sliding magnet and the second holder magnet is opposite the second sliding magnet.

6. The system of claim 4 , wherein the holder surface is only partially bounded, and wherein the first holder magnet is in the slot and the second holder magnet is outside the slot, and wherein:

in a first assembled configuration, the first sliding magnet is opposite the second holding magnet; and

in a second assembled configuration, the sliding member is fully inserted into the slot, the first holder magnet is opposite the first sliding magnet and the second holder magnet is opposite the second sliding magnet.

7. The system of claim 6 , wherein the first assembled configuration initially retains the sliding member when inserting the sliding member into the holder and finally retains the sliding member when removing the sliding member from the holder, and wherein the first assembled configuration is a transitional configuration between the second assembled configuration and fully detaching the sliding member from the holding member.

8. The system of claim 6 , wherein in the second assembled configuration, the first holder magnet retains the sliding member at the end of its travel within the slot, and wherein the first and second holder magnets combine to securely retain the sliding member in the slot, and wherein the boundary of the slot prevents rotation of the sliding member relative to the holder device.

9. The system of claim 4 , wherein the holder surface is only partially bounded, and wherein the first holder magnet is in the slot and the second holder magnet is outside the slot.

10. The system of claim 4 , wherein both the first and second holder magnets are within the bounded portion of the holder device surface.

11. The system of claim 4 further comprising an accessory holder fixed to the sliding member.

12. The system of claim 11 , wherein the accessory holder is a cup holder.

13. The system of claim 4 further comprising an accessory fixed to the sliding member.

14. The system of claim 13 , wherein the accessory is a purse.
