SPRING-LOADED COUPLING MECHANISM
BACKGROUND OF THE INVENTION
This invention relates to a spring-loaded coupling mechanism which is capable of coupling together two objects such as mooring a boat to a dock or on a trailer.
Most objects which are hingedly coupled to other complimentary objects are essentially permanently coupled to each other such as lids being coupled to containers. Those objects which are not permanently coupled together are coupled together with rope or with a hook and loop. For example, coupling or mooring a boat to a dock includes using a rope having a loop at one end and being tied to the boat at the other end with the loop being adapted to slip over the top o~
a post on the dock. Securing a boat on a trailer includes a rope having a hook at one end which is adapted to clip or hook about a loop connected to the boat. Other types o~ coupling means includes the ~ollowing:

Yet, another objective o~ the present invention is to provide a spring-loaded coupling mechanism which allows the user to quickly couple and de-couple two objects together by simply inserting the connecting member inside the housing until it becomes securely engaged therein.
Further objectives and advantages o~ the present invention will become apparent as the description proceeds and when taken in conjunction with the accompanying drawings wherein:
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a rear perspective view o~ the spring-loaded coupling mechanism.
FIG. 2 is a side elevational view o~ the spring-loaded coupling mechanism showing, in particular, a longitudinal cross-sectional view o~ the housing and the connecting member engaged therein.

DETAILED DESCRIPTION OF THE INVENTION
Re~erring to the drawings in FIGS. 1-3, in particular, the spring-loaded coupling mechanism comprises a tubular housing 15 having a ~orward end 15A and a rearward end 15B
with each end having a hole 15Al-Bl therethrough into an internal cavity 15C o~ the housing 15, a ~orward portion o~
the cavity 15C being tapered inwardly and toward the ~orward CA 0224914~ 1998-09-29 end 15A of the housing 15. A catch member 20, at least a portion of which has a generally right angle longitudinal cross-section, is movably disposed inside the internal cavity 15C of the housing 15 and is fixedly attached by conventional means to a first elongate support member 21 which movably extends through the hole 15Bl in the rearward end 15B of the housing 15; wherein, the catch member 20 is positioned inside the housing 15 such that the right angle longitudinal cross-section faces toward the tapered portion 15D of the cavity 15C
and toward the forward end 15A of the housing 15. As shown in FIG. 2, a spring member 22 is disposed inside the housing 15 and is mounted about the ~irst elongate support member 21 and has an end which rests against the inner side of the rearward end 15B of the housing 15 and biasedly seats the catch member 20 in the tapered portion i5D of the housing 15. The portion of the first elongate support member 21 not extendable inside the housing 15 is attached or connected by conventional means to an object which is capable o~ being coupled to another object which is attached to a second elongate support member 26 which has an end fixedly attached by conventional means to a substantially round connecting member 25 which is extendable and releasably securable inside the housing 15 through the hole 15Al in the forward end 15A. A first stop member 27A is fixedly mounted by conventional means about the second elongate support member 26 a selected distance ~rom the connecting member 25, and a second stop member 27B is movably CA 0224914~ 1998-09-29 mounted about the second elongate support member 26 between the connecting member 25 and the first stop member 27A. A
compression spring means 28 is mounted about the second elongate support member 26 and has one end resting against the ~irst stop member 27A and has the other end ~ixedly attached or welded to the second stop member 27B and biases the second stop member 27B into contact with the outerside of the forward end 15A of the housing 15 when the connecting member 25 is securely engaged inside thereof. Once the connecting member 25 is secured inside the housing 15, the spring means 28 urges against the ~irst stop member 27A with the second stop member 27B being in contactable relationship with the forward end 15A
of the housing 15 to substantially tighten the second elongate support member 26 which essentially insures that the connecting member 25 remain securely engaged either between the catch member 20 and the wall of the housing 15 or behind the catch member 20.
To use the spring-loaded coupling mechanism, the user ties one end of the first elongate support member 21 which is not extendable inside the housing 15 to an object such as a dock and ties one end o~ the second elongate support member 26 which is also not extendable inside the housing 15 to another object such as the bow of a boat; and then moves the first elongate support member 21 rearwardly relative to the housing 15 so as to unseat the catch member 20 from the tapered portion 15D of the housing 15, the catch member 20 being CA 0224914~ 1998-09-29 seated in the tapered portion 15D o~ the cavity 15C; and then extends the round connecting member 25 through the hole 15Al in the ~orward end 15A o~ the housing 15 beyond the tapered portion 15D; and then releases the ~irst elongate support member 21 to allow the catch member 20 to move into engagement with the connecting member 25 which is either received in the right angle longitudinal cross-section o~ the catch member 20 and securely engaged between the catch member 20 and the interior o~ the housing 15 or engaged behind the catch member 20 between the catch member 20 and the rearward end 15B o~ the housing 15; wherein the catch member 20 prevents the connecting member 25 ~rom exiting the housing 15 through the hole 15Al in the ~orward end 15A either by blocking the passage through the housing 15 with the connecting member 25 being to the rearward side o~ the catch member 20 which is biasedly seated in the tapered portion 15D o~ the housing 15 or by receiving the connecting member 25 in the right angle cross section and engaging the connecting member 25 between the catch member 20 and the wall o~ the housing 15, in particular, the tapered portion 15D o~ the cavity 15C. By the connecting member 25 being releasably secured inside the housing 15 by the catch member 20, the objects which are attached to the respective lines are coupled together.
Optionally, a ~unnel-like member 18 is conventionally and ~ixedly attached to and extending ~rom the ~orward end 15A o~
the housing 15 to ~acilitate the coupling or extending o~ the CA 0224914~ 1998-09-29 connecting member 25 through the hole 15Al in the forward end 15A of the housing 15 by funneling the connecting member 25 toward the hole 15Al in the forward end 15A o~ the housing 15.
To de-couple the objects, the user urges the first elongate support member 21 rearwardly relative to the housing 15, which un-seats the catch member 20 from the tapered portion 15D and disengages the catch member 20 from the connecting member 25 which, because of the force of the spring means 28 on the second elongate support member 26, exits the housing 15 through the hole 15Al in the forward end 15A
thereof. The user only has to momentarily move the first elongate support member 21 rearwardly sufficient to disengage the catch member 20 from the connecting member 25. Many objects can be easily and conveniently coupled together by using this spring-loaded coupling mechanism.
Various changes and departures may be made to the invention without departing ~rom the spirit and scope thereof.
Accordingly, it is not intended that the invention be limited to that specifically described in the speci~ication or as illustrated in the drawings but only as set forth in the claims.
