Each of the fastening portions has a threaded section at an inner side thereof. The second ring member has a bore at a center thereof and a plurality of stop portions, each of which has a stop face on a distal end thereof. The fastening portions of the first ring member is inserted into the bore of the second ring member that the second ring member may be moved along the fastening portions of the first ring member, and the second ring member will bend the fastening portions inwards when the second ring member is moved toward distal ends of the fastening portions.

French Abstract

Écrou rapide comportant un premier et un second éléments annulaires. Le premier élément annulaire comporte un alésage en son centre et des parties de fixation autour dudit alésage. Chacune des parties de fixation comporte une partie filetée et un côté intérieur connexe. Le second élément annulaire comporte un alésage en son centre et une série de butées, chacune de ces dernières étant munie d'une surface de butée sur son extrémité distale. Les parties de fixation du premier élément annulaire sont insérées dans l'alésage du second élément annulaire de façon à ce que ce dernier puisse être déplacé le long des parties de fixations du premier élément annulaire; le second élément annulaire replie alors les parties de fixation vers l'intérieur lorsque le second élément annulaire est déplacé vers les extrémités distales des parties de fixation.

QUICK FASTENING NUT
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a fastener and, more particularly,
to a quick fastening nut.
2. Description of the Related Art
Typically, to secure a product having a thread to an object, a nut usually is
involved. For example, to mount a faucet on a table, a tube having a thread on
a back
of the faucet is inserted into a bore of the table, and a nut is screwed onto
the tube from
a back of the table to secure the faucet on the table. It takes a lot of time
in screwing
the nut when secure the faucet. For some conditions, such as the thread is
long or it
doesn't have enough space to screw the nut, it will take longer time to screw
the nut.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a quick fastening
nut which has a quick and simple way to fasten and release the nut,
furthermore, it
provides a firm connection.
To achieve the objective of the present invention, a quick fastening nut
includes a first ring member and a second ring member. The first ring member
has a
bore at a center thereof and fastening portions around the bore. Each of the
fastening
portions has a threaded section at an inner side thereof. The second ring
member has a
bore at a center thereof and a plurality of stop portions, each of which has a
stop face
on a distal end thereof. The fastening portions of the first ring member is
inserted into
the bore of the second ring member that the second ring member may be moved
along

the fastening portions of the first ring member, and the second ring member
will bend
the fastening portions inwards when the second ring member is moved toward
distal
ends of the fastening portions.

DETAILED DESCRIPTION OF THE INVENTION
As shown in FIGS. 1 to 3, a quick fastening nut of the first preferred
embodiment of the present invention includes:
2

CA 02632368 2008-05-27
A first ring member 10 includes a ring 11 having a bore 12 at a center thereof
and two gaps 13 extended inwards from an edge thereof. The first ring member
10
further includes two fastening portions 14 projected from a side of the ring
11 between
the bore 12 and the gaps 13 respectively. Each of the fastening portions 14
has a
thickness gradually greater from a proximal end to a distal end that a
distance between
outer sides of the distal ends of the fastening portions 14 is greater than
that of between
outer sides of the proximal ends of the fastening portions 14. Each of the
fastening
portions 14 has a threaded section 15 on an inner side thereof, and a length
of the
threaded section 15 is equal to or less than 2/3 of a length of the fastening
portion 14.
A second ring member 20 includes a ring 21 having a bore 22 at a center
thereof. A diameter of the bore 22 of the ring 21 of the second ring member 20
is
greater than that of the bore 12 of the ring 11 of the first ring member 10.
The second
ring member 20 further includes two stop portions 23 projected from a side of
the ring
22, each of which has a stop face 24 at a distal end thereof. Basically, a
number of the
gaps 13 of the first ring member 10 is identical to the stop portions 23 of
the second
ring member 20. The first ring member 10 has the fastening portions 14
inserted into
the bore 22 of the second ring member 20, and the stop portions 23 of the
second ring
member 20 extended through the gaps 13 of the first ring member 10 that the
first ring
member 10 and the second ring member 20 are connected together. In this
condition,
the second ring member 20 cannot rotate relatively because of the engagement
of the
gaps 13 and the stop portions 23, but is still allowed to move axially
relative to the first
ring member 10. In other words, the gaps 13 form a restrict portion to allow
the first
ring member 10 moving relative to the second ring member 20 but rotating.
To fasten a faucet having a threaded tube S by the quick fastening nut of the
first preferred embodiment of the present invention, as shown in FIG. 4, user
fits the
3

CA 02632368 2008-05-27
bore 12 of the first ring member 10 to the threaded tube S. In this step, the
second ring
member 20 is at the proximal ends of the fastening portions 14 so the quick
fastening
nut of the present invention is free to move along the threaded tube S. When
the quick
fastening nut of the present invention arrives a proximal end of the threaded
tube S, as
shown in FIG. 5, the stop face 24 of the second ring member 20 will touch a
bottom of
a table first that the second ring member 20 is stopped and the first ring
member 10 is
still free to move. Next, user may move the first ring member 10 continuously
that will
cause the ring 21 of the second ring member 20 moving toward the distal ends
of the
fastening portions 14 and bending the fastening portions 14 inwards. This will
engage
the threaded sections 15 of the fastening portions 14 with the threaded tube
S. As the
harder the first ring member 10 is pushed, the tighter the engagement of the
fastening
portions 14 and the threaded tube S is. To secure the faucet more tightly,
user may turn
the quick fastening nut of the present invention, like screwing a nut.
To release the quick fastening nut of the present invention, user turns the
first
ring member 10 reversely to move the first ring member 10 away from the table
and let
the second ring member 20 may be moved to the distal ends of the fastening
portions
14 that will disengage the fastening portions 14 with the threaded tube S and
draw the
quick fastening nut of the present invention out of the threaded tube S
quickly.
As shown in FIG. 6 and FIG. 7, a quick fastening nut of the second preferred
embodiment of the present invention, which is similar to the first preferred
embodiment, includes a first ring member 10 and a second ring member 20. The
different part is that the first ring member 10 further has two protrusions 16
projected
from a ring 11. The protrusions 16 and fastening portions 14 are on the same
side of
the ring 11. Each of the protrusions 16 has textures 17 thereon. The function
of the
protrusions 16 is that user may hold the protrusions 16 to turn the quick
fastening nut
4

CA 02632368 2008-05-27
of the second preferred embodiment of the present invention.
FIG. 8 and FIG. 9 shows a quick fastening nut of the second preferred
embodiment of the present invention, which is similar to the first preferred
embodiment, including a first ring member 10 and a second ring member 20. The
first
ring member 10 has two fastening portions 14, each of which has a constant
thickness
and a plurality of ribs 17 on an outer side thereof. Theses ribs 17, as shown
in FIG. 9,
have triangular shapes that heights thereof are gradually greater from an end
proximal
to the proximal ends of the fastening portions 14 to the other ends proximal
to the
distal ends of the fastening portions 14. The operation of the quick fastening
nut of the
second preferred embodiment is as same as the first preferred embodiment that
the ribs
17 is functional to bend the fastening portions 14 when the second ring member
20 is
move toward the distal ends of the fastening portions 14.
Although the particular embodiments of the invention has been described in
detail for purposes of illustration, various modifications and enhancements
may be
made without departing from the spirit and scope of the invention.
Accordingly, the
invention is not to be limited except as by the appended claims.
