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.

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.
