Abstract
A D-Ring assembly comprises a base having a ring integrally formed therewith and protruding from the top surface of the base, and a grommet having an aperture therethrough. The grommet covers the base so that the ring protrudes through the aperture. In use, the base is mounted underneath the fabric or trim of a briefcase or other item, with the ring protruding through a hole in the fabric. The grommet is mounted on top of the base and fabric and secured to the base. The ring protrudes through the hole in the grommet and can be used to attach straps or other items to the assembly. This assembly is very secure because it does not depend on the strength of a narrow fabric or leather strap to stay mounted. It is also very sleek and attractive because it only protrudes a small amount from the surface of the bag or item to which the assembly is attached.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a D-Ring for attaching straps to luggage and other items. In particular, the invention relates to a D-ring that is secured to the bag or other item via a grommet that surrounds the base of the ring and keeps the ring securely fastened.
2. The Prior Art
Straps are often releasably secured to briefcases and luggage via D-rings that are sewn onto a loop on the bag. A hook on the strap is then snapped onto the D-ring to secure the strap to the bag. This arrangement is a convenient way to removably attach straps to items. However, the D-rings often fall off of the bag, due to stress on the sewn loop. In addition, the loop and D-ring can protrude excessively from the bag, creating an unattractive appearance, especially when the bag is used without its straps.
SUMMARY OF THE INVENTION
It is therefore an object of the invention to provide a D-ring that securely attaches to a bag or other item without the risk of removal or tearing of the bag.
It is another object of the invention to provide a D-ring that is unobtrusive and does not detract from the appearance of the bag or item to which it is attached.
It is yet another object of the invention to provide a D-ring that is simple and inexpensive to manufacture and install.
These and other objects of the invention are accomplished by a D-Ring assembly comprising a base having a ring integrally formed with and protruding from the top surface of the base, and a grommet having an aperture therethrough. The grommet covers the base so that the ring protrudes through the aperture. In use, the base is mounted underneath the fabric or trim of a briefcase or other item, with the ring protruding through a hole in the fabric. The grommet is mounted on top of the base and fabric and secured to the base. The ring protrudes through the hole in the grommet and can be used to attach straps or other items to the assembly. This assembly is very secure because it does not depend on the strength of a narrow fabric or leather strap to stay mounted. It is also very sleek and attractive because it only protrudes a small amount from the surface of the bag or item to which the assembly is attached.
The base and grommet can be attached to each other by any suitable means. One way is with screws that extend through holes in both the base and grommet. This would secure the base to the fabric of the bag as well as to the grommet. Another way is to mold studs on to either the base or the grommet and mold stud receptacles on the other part. The pieces can then be secured together by simply snapping the studs into the stud receptacles. Here, the studs also extend through the fabric of the bag to secure the entire assembly to the bag as well.
While the assembly according to the invention can be mounted on any part of the bag, it is often preferable to mount the assembly on a corner of the bag. This is especially true if the strap to be attached is a shoulder strap. For corner mounting, the base and grommet are curved so that the assembly can curve around the corner of the bag. Other shapes could also be envisioned, depending on the location of the assembly on the bag.
The assembly is preferably made of molded plastic.
BRIEF DESCRIPTION OF THE DRAWINGS
Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood, however, that the drawings are designed as an illustration only and not as a definition of the limits of the invention.
In the drawings, wherein similar reference characters denote similar elements throughout the several views:
FIG. 1
shows a perspective view of the base and grommet of the assembly according to the invention;
FIG. 2
shows an exploded side view of the base and grommet according to the invention;
FIG. 3
shows a side cross-sectional view of the assembly as mounted on the corner of a bag; and
FIG. 4
shows an exploded side view of an alternative embodiment of the D-ring assembly according to the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now in detail to the drawings and, in particular,
FIGS. 1 and 2
, there is shown the D-ring assembly comprising a base
10
and a grommet
20
. Base
10
base a central aperture
11
and a protruding D-ring
12
molded integrally with base
10
. There are screw holes
13
and
14
disposed within cavities
15
and
16
on base
10
.
Grommet
20
has a central aperture
21
, with side slits
22
and
23
to accommodate D-ring
12
when grommet
20
is mounted over base
10
. Slits
22
and
23
keep base
10
from moving laterally after grommet
20
is mounted on top.
To mount the assembly on an item such as a briefcase, base
10
is inserted beneath the outer fabric layer of the briefcase
30
, and is disposed adjacent the inside surface of briefcase
30
, as shown in FIG.
3
. D-ring
12
then protrudes through a hole in the fabric to be visible from the exterior of briefcase
30
. Grommet
20
is then placed over base
10
and briefcase
30
, adjacent the outside surface of briefcase
30
and base
10
and grommet
20
are secured together with screws
24
and
25
, as shown in FIG.
2
. Grommet
20
has protrusions
31
and
32
, which fit within cavities
13
and
14
on base
10
to help align base
10
with grommet
20
. Screws
24
and
25
are inserted from behind base
10
and extend up through protrusions
31
and
32
on grommet
20
to secure base
10
and grommet
20
together.
An alternative embodiment of the invention is shown in FIG.
4
. Instead of screws to fasten base
10
and grommet
20
together, base
10
is comprised with two studs
26
and
27
, which can be snapped into receptacles
28
and
29
on grommet
20
. Alternatively, studs
26
and
27
could be located on grommet
20
with receptacles
28
and
29
on base
10
. Any suitable fastening arrangement could be used to secure base
10
to grommet
20
and the invention is not limited to any particular fastening arrangement.
The embodiment shown in
FIGS. 1-4
has a curved profile that is especially adapted for mounting on the corners of bags and briefcases. This location is preferred when mounting shoulder straps. However, the D-ring assembly according to the invention could be manufactured with a straight profile, for mounting on the face of an item. Other shapes could also be made, depending on the surface to which the assembly is mounted. The assembly is preferably made of a heavy duty plastic material, but any suitable material could be used.
Since the D-ring assembly according to the invention is secured to briefcase
30
through the fabric of briefcase
30
, it is a very secure, low-profile arrangement. There is very little risk that base
10
will break through fabric
30
under stress, especially due to the large surface area of base
10
. The assembly is very attractive and does not protrude unnecessarily from briefcase
30
. D-ring
12
can be very low profile, because apertures
21
on grommet
20
and
11
on base
10
provide sufficient clearance for a snap hook or other type of fastener to be inserted underneath D-ring
12
to attach a strap to briefcase
30
.
Accordingly, while only a few embodiments of the present invention have been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
