Multi-purpose key ring

Abstract

A metallic multi-purpose key ring comprised of a shackle in D-shape having a gap, a cartridge with both ends pivoted to a joint and a stopper respectively provided on both ends of the gap and a can opener provided on top of the shackle to provide effective positioning and latching between said shackle and cartridge.

Description

BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The present invention relates to a multi-purpose key ring and more particularly to one made of metallic material and has a built-in can opener with a flexible member provided at the bottom of a gate for effective positioning and latching.

[0003] (b) Description of the Prior Art

[0004] A key ring generally available in the market is essentially comprised of a metal piece in a ring shape by taking advantage of the tension and elasticity of the metal piece. Keys are placed into the ring through key eyes. A latching piece is adapted as a gate to the ring to buckle to anywhere as the owner thinks fits best.

[0005] However, upon inserting the key to the ring, the gate must be pulled up and the pull may be not so easy due to excessive tension and elasticity of the metal piece. Consequently, the key ring usually does not come so handy to its owner.

SUMMARY OF THE INVENTION

[0006] The primary purpose of the present invention is to provide a multi-purpose key ring essentially comprised of a shackle, a cartridge and a can opener. To achieve the purpose, said cartridge is provided as the gate to the key ring and contains an elastic member for effective positioning and latching between the shackle and the cartridge; and said can opener is built in the top of the shackle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Referring to FIGS. 1 and 2, a preferred embodiment of the present invention is essentially comprised of a shackle 1, a cartridge 2 and a can opener 3. Wherein, said shackle 1 relates to a D-shape ring having a gap; a joint 13 having a lateral groove 131 and a hole 132 penetrating the shackle is provided at one end of the shackle 1; and a stopper 12 is provided on the other end of the shackle 1. A longitudinal groove 11 is provided on the shaft 1 to accommodate the can opener 3 and a hole 111 penetrates through said groove 11 to pivot said can opener 3. Said cartridge 2 relates to a hollow tube slightly longer than the gap of the shaft 1 having its one end provided a carrier 23 to contain a elastic tag 22 inserted with a coil 21. A cut 25 provided at the opening of the carrier 23 has a hole 251 to penetrate said cartridge 2 and a positioning groove 24 to receive said stopper 12 is provided on the other end of the cartridge 2 to prevent lateral displacement of the stopper. Said can opener is made of metallic material.

[0012] When assembled, the elastic tag 22 inserted with the coil 21 is placed into the cartridge 2 and the cut 25 in the cartridge 2 is pivoted to the joint 13 on the shaft 1. The side of the cartridge 2 having the positioning groove 24 is facing away from the shackle 1. A bolt 26 passes through the holes 251, 132 respectively provided in the cartridge 2 and the shaft 1 for the cartridge 2 to pivot on the shaft 1 and the elastic tag 22 in the cartridge 2 to hold against the lateral groove 131 on the shaft 1. Said can opener 3 is pivoted with another bolt 14 in the longitudinal groove 11 on the shaft 1.

[0013] In use, the cartridge 2 pivoted to the shaft 1 is pushed inside to allow the key eye to be placed into the shaft, and the ring indicates a closed status with the positioning groove 24 on the cartridge 2 holding against the stopper 12 on the shaft 1 for a fast placement and agile use of the key by positioning and latching between the shaft 1 and the cartridge 2.

[0014] As disclosed above, a multi-purpose key ring of the present invention executes effective positioning and latching for a fast and handy use of the key ring and the key ring is innovative to comply with requirements of patent law. Therefore, an application for a utility patent is duly filed accordingly.

Claims
