Spinner key ring with locking interchangeable parts
Abstract
A spinner key ring with locking interchangeable parts is
provided. The locking system consists of a set pin and a locking
screw or pin that locks the center piece to the outer ring. The
spinner key ring has an outer metal ring with a loop called the
earpiece at the top, which connects to a chain and then to a split
ring to hold keys. The earpiece itself is drilled through the
middle to allow the screw to go through the outer ring and into the
centerpiece. The length of the screw is 5 millimeters. On the
opposite side of the outer ring from the earpiece is a 3-millimeter
fixed pin, which the center piece seats onto. Once the centerpiece
is seated, the screw is inserted through the earpiece. Using this
system the centerpiece is locked into place and is also
interchangeable. The system can be used with any shaped outer
ring.

Claims
What is claimed is:
1. An assembly system for spinner key rings with lockable
interchanging parts: a screw inserted through the ear piece of an
outer metal ring into the centerpiece, with a fixed stem connected
to the outer ring on the opposite side, creates a lockable assembly
that is also interchangeable by unscrewing the screw from the ear
piece and raising the centerpiece to remove off the fixed pin
below, then a new center can be inserted and locked.
2. An assembly system for spinner key rings with lockable
interchanging parts according to claim 1 results in an unbreakable
key ring.
3. An assembly system for spinner key rings with lockable
interchanging parts according to claim 1 results in a key ring that
can change by removing the centerpiece.
Description
RELATED APPLICATIONS
[0001] This application should be cross-referenced with application
Ser. No. 60/377,753 which was filed May 6, 2002 and is titled
spinner key ring with locking interchangeable parts.
TECHNICAL FIELD
[0002] The present invention relates to a lockable assembly system
for spinner key rings which, are metal key rings that have an outer
metal ring and then in the center is a spinning piece.
BACKGROUND OF THE INVENTION
[0003] Spinner key rings have typically been assembled using
watchband spring assemblies, which tend to pop apart causing the
centerpiece to fall out. There is a need to create a spinner key
ring that won't fall apart. There is a need for a stronger assembly
than the current watchband pin, which is weak and breaks with
little pressure.
SUMMARY OF THE INVENTION
[0004] The present invention provides a fixed, strong, and lockable
device for securing an inner spinning piece to the outer ring of a
spinner key ring. In particular, the present invention provides a
novel system for securing these two metal objects together.
[0005] The novel securing system of a raised pin on one side and a
screw on the other results in a key ring that spins freely and
won't fall apart. By putting a fixed pin on one side, then
inserting the center piece, and then from the top a screw goes
through the earpiece into the center piece, resulting in a secure
spinning key ring.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is a side view of the locking screw system.
[0007] FIG. 2 is a graphic of what a spinner key ring looks like
with the centerpiece in place.
DETAILED DESCRIPTION OF THE INVENTION
[0008] Referring now in specific detail to the drawings of FIG. 1
at the bottom of the outer ring 10 is a 3 mm-fixed pin 12. At the
top is an earpiece 14 and a whole 16 has been drilled through the
top of the solid earpiece 14 and another whole 18 is drilled
through the outer ring 10. A centerpiece 22 is then inserted and
seated onto the fixed pin 12 and then screwed down from the top,
securing the assembly. In certain occasions spacers may be added
between the pin 12 and the outer ring and/or the screw and the
outer ring 10 to better space the centerpiece.
[0009] FIG. 2 is a drawing of a spinner key ring with a heavy metal
cube as the center. The fixed pin is located at the bottom and the
screw would come through the center circular earpiece 22 at the top
securing the heavy metal cube in the center. A spacer is sometimes
located between the center piece and the pin and/or screw to center
the middle piece resulting in it spinning freely.
[0010] While the invention has been particularly shown in a round
and rectangular format it will be understood that both the outer
and inner piece can be any shape or size.
[0011] While the invention has been particularly shown with the pin
at the bottom and the screw at the top it will be understood that
the pin and screw could be in any area of the outer ring.
[0012] While the invention has been particularly shown with one
outer ring and one centerpiece it will be understood that there
could be multiple spinning pieces in the center by using a longer
pin and screw.
