## Background
This application claims the benefit of Provisional Application No. 61/215,370, filed May 4, 2009, the subject matter of which is hereby incorporated in its entirety by reference thereto.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to interchangeable attachments for collars, leashes, belts and accessories, such as bags and backpacks; and more particularly, to interchangeable attachments having various designs, LED and/or reflective properties, that are readily removably attached to a portion of a collar, leash, belt and/or accessory, to provide aesthetic appeal and enhance visibility of the items with which they are associated, thereby increasing user safety while walking in the vicinity of land vehicles during dusk or nighttime hours.
2. Description of the Prior Art
Walking during dusk or nighttime hours can be hazardous in neighborhoods where automobiles are encountered. Illuminating characteristics of the automobile headlamps, generally afford an illumination range of approximately 25 to 50 feet. This illumination range can be significantly reduced by mist or fog, or bends in the road. Despite improvements to vehicle headlights, pedestrians, as well as pets and their owners walking, are oftentimes not recognized by automobile drivers until the distance between the automobile and the pedestrian or pet is small.
Several approaches devised by prior art workers attempt to provide solutions for safety concerns of pedestrians and pets. These approaches include 1) use of pet collars that are illuminated or reflective; 2) use of leashes which are illuminated or reflective; or 3) a combination of both features. None of these solutions suggest indicating the whereabouts of a pet owner, a leash and a pet attached to the leash, or a pedestrian or child via LED or reflective attachments appointed to removably attach to a leash, collar, or accessory, such as a backpack.
Various types of illuminated dog collars using bulb or other powered sources are known in the art. These power-illuminated leashes require batteries, light bulbs or other lighting elements, and are not provided as decorative, removable attachments. For examples, see: U.S. Pat. Nos. 4,173,201; 4,513,692; 4,895,110; 4,887,552; 5,046,456; 5,140,946; 5,370,082; 5,429,075; 5,523,927; 5,535,106; 5,558,044; 5,630,382; 5,762,029; 5,850,807; 5,967,095; 6,170,968; 6,289,849; and 6,557,498. None of these power-illuminated leashes provides decorative, removable LED attachments and/or decorative reflective attachments. Dog collars, harness and leashes which include reflection capabilities are known in the art., but each fail to provide decorative attachments including reflective properties. For examples, see: U.S. Pat. Nos. 3,871,336; 3,999,521; and 4,167,156.
Beyond safety concerns, many individuals and children prefer to personalize their accessories, such as belts, bags and backpacks, in a manner that does not permanently alter the accessory. However, these designs and other decorative items require permanent application to the accessory. Further, many pet owners like to decorate their pets and utilize jeweled collars and the like. Unfortunately, collars and leashes which include designs are not designed uniquely by the individual and are permanent in nature.
Some decorative devices for leashes have been provided, however the decorative devices fail to provide a plurality of decorative removable attachments, and further fail to provide the ability for an individual to readily change the decoration when desired. For examples, see: U.S. Pat. Nos. 5,363,809; 7,350,342; and 7,421,980.
Notwithstanding the efforts of prior art workers to construct decorative collars, leashes, belts and/or accessories, there is a need in the art for interchangeable attachments appointed to be removably attached to collars, leashes, belts and accessories. Additionally, there is a need in the art for interchangeable attachments having various designs, LED and/or reflective properties that are removably attached to a portion of a collar, leash, belt and/or accessory, to provide aesthetic appeal and/or to provide pedestrians with enhanced visibility and increased safety from vehicles during dusk or nighttime hours.
SUMMARY OF THE INVENTION
The present invention provides interchangeable attachments appointed to be removably attached to collars, leashes, belts and accessories. A plethora of designs are provided on the show surface of the subject interchangeable attachments. The interchangeable attachments are provided via various designs and may further include LED and/or reflective properties integrated therein so that the attachments can be readily removably attached to a portion of a collar, leash, belt and/or accessory, to provide aesthetic appeal and/or to provide enhanced safety from vehicles during dusk or nighttime hours. Further, the show surface of the interchangeable attachments may have different textured appearances, such as smooth, silky, rough, leather, metallic or jeweled. In one embodiment the interchangeable attachments are presented as snap-in button-type attachments and/or magnetic attachments. In another embodiment the interchangeable attachments are provided as elongated attachment portions that removably adhere to a central section of a body of a collar, leash, bag strap, or belt to provide an interchangeable show surface and ultimately change the look of the article.
This invention pertains to attachments for accessories, such as bags and back packs, and pet accessories, such as leashes and collars for household pets, that can be individualized by a person or a pet owner and offer high visibility at dusk, and in other dimly lit environments. In one embodiment, a plurality of LED Buttons can be secured to a pet collar or leash, to improve visibility during daytime and nighttime excursions with the pet. Applications are appointed for use on leashes and collars, as well as for use on bags, backpacks, and belts.
In an alternative embodiment, a plurality of holes are integrated in a leash or collar central section, or a central section of a strap of a bag or a portion of a belt, that are appointed to receive a decorative attachment. The decorative attachments may be of a plethora of designs and may include an LED integrated therein, and/or reflective properties. Attachments may be created to accept the LED or any kind of Optics that are used for fun and to create a more visible pet or person. The attachments provided as LED buttons, optics, gems, or charms are to be inserted into the designed holes to create a more individual piece, while providing enhanced safety via more visibility. Enhanced safety is not only afforded, but the attachments allow a user freedom of choice to design a creation of their own individual preference. Shapes, sizes and designs presented by the plethora of attachments are all different. Selection of the attachments as well as arrangement on the leash, collar or accessory is uniquely determined by the person. Preferably, the attachments are presented as snap on buttons and are sold in a package containing at least one attachment, or more than one. The snap in attachments have a back piece that lays flat once inserted through the hole, or may have a ball like end that inserts and remains secure when in place, so the back portion of the attachment or LED or optic button/charm piece may vary in design. Alternatively, the attachment may be an independent piece retrofitted with a clip-like backing that holds it in place against the strap. The LED's and the optic light are used with a small watch battery, and last a long time, so battery life does not become a concern.
In another embodiment, the attachment is provided as an interchangeable elongated central section overlay which is appointed to be removably received over the central section of a leash or collor portion. Preferably, mating hook and loop fastener portions (such as sold under the trademark VELCRO) are provided on the elongated central overlay attachment and central section of the leash or collar portion. Preferably, the elongated attachments are sold with the collar, and/or leash, or bag, or belt to offer an alternative design. In operation, the user simply presses the elongated attachment to removably affix it the central section of the body of the collar, leash, or bag, and a new look or design yields. For removal, the user simply peels the elongated attachment from the central section of the body of the collar, leash, and/or bag. Reflective material or LED or fiber optics may be integrated within the elongated attachment for extra visibility when wearing. The elongated attachments can be used on bag or backpack straps and/or belts, particularly for children.
An interchangeable attachment for an article, including pet collars and leashes, belts, bags and backpacks is provided. The article has at least one elongated region comprising a proximal end, distal end and a central section having at least one connection means appointed to receive an interchangeable attachment.

DETAILED DESCRIPTION OF THE INVENTION
The present invention provides interchangeable attachments for an article, including pet collars and leashes, belts, bags and backpacks. The article has at least one elongated region comprising a proximal end, distal end and a central section having at least one connection means appointed to receive an interchangeable attachment. The interchangeable attachment includes a top wall having a show surface and a back wall having a securing member adapted to engage with the connection means of the article for removably attaching the interchangeable attachment to the article. In one embodiment the interchangeable attachments are provided as button-type attachments. In another, the interchangeable attachment is provided as an elongated attachment portion appointed to substantially cover the central section of the elongated region of the article. The interchangeable attachments have a plethora of designs and may include LED, fiber optic and/or reflective properties to provide both aesthetic appeal and enhance safety during nighttime or dusk hours.
FIG. 1 is a schematic view of an embodiment of the interchangeable attachment for an article, wherein a plurality of interchangeable attachments are provided as button-type or snap on attachments added-onto a pet leash and pet collar, shown generally at 10. FIG. 1 further shows an expanded view of an interchangeable attachment having a shaft portion and an end cap portion and the leash connection means being an aperture, shown generally at 50. The article herein is shown as a leash and collar; however, the article can be a belt, purse, bag or backpack, or pet carrier (for an illustration of the back pack see FIG. 5a-5b). A leash and collar are shown with a plurality of interchangeable attachments added-on to the articles (leash 11 and collar 12). Leash 11 and collar 12 each have at least one elongated region comprising a proximal end 11a, 12a, distal end 11c, 12c and a central section 11b, 12b. Proximal end 11a of leash 11 includes a handle 13, while distal end 11c includes a clasp 14 (or may be looped and formed into a choke collar). Distal end 12c of collar 12 includes a buckle 15 appointed to receive proximal end 12a of collar 12 to clasp around a dog's neck. The central section 11b, 12b of the leash 11 and collar 12 have at least one connection means 16 (16a-n) appointed to receive interchangeable attachments 20. Preferably a plurality of connection means 16 (16a-n) are provided as shown, extending substantially along the length of central section 11b, 12b of leash 11 and collar 12. Optionally, there may be provided only a small group of three or four connection means 16 (16a-n) provided along the length of central section 11b, 12b of leash 11 and collar 12.
As best illustrated at 50, the interchangeable attachments 20 (20a-n) include a top wall 21 having a show surface 22, side walls 23 (preferably shallow), and a back wall 24 having a securing member 25 integrated therein. Securing member 25 is adapted to engage with connection means 16 (16a-n) of central section 11b (or in the case of the collar 12, central section 12b) of the leash 11 for removably attaching the interchangeable attachment 20 (20a-n) to the leash 11 (or collar 12). Connection means 16 (16a-n) comprises at least one aperture as shown at 55. In the embodiment shown, securing member 25 of the interchangeable attachment 20 comprises a shaft portion 56 with a shaft end 57. Shaft portion 56 is received and housed within the aperture 55 comprising connection means 16 of central section 11b, 12b so that the interchangeable attachment 20 is removably attached to the leash 11, or collar 12. A locking cap 58 may be provided that is appointed to receive shaft end 57 of the shaft portion 56. Optionally, the securing member 25 (via shaft 56) of the interchangeable attachment 20 is composed of a magnetic material. Conversely, the connection means 16 (16a-n), herein apertures 55, of leash 11 or collar 12 would then be composed of a metal material.
Alternatively, securing member 25 of the interchangeable attachment 20 comprises a shaft portion 56 with a shaft end 57 formed as a bulbous portion (not shown) having a bulbous diameter slightly greater than the aperture 55 diameter of connection means 16 (16a-n). For ease of insertion into aperture 55, preferably the bulbous portion of the interchangeable attachment 20 is composed of a flexible or deformable material.
The show surface 22 of the interchangeable attachment 20 may include a gemstone, decorative glass or other decorative design piece attached thereto. In yet another embodiment, the interchangeable attachment 20 includes an electroluminescent light (LED) or fiber optics integrated therein, both for decoration purposes as well as to provide safety to a person or pet. As shown at 50, the electroluminescent light 61 is housed under top wall 21, which is provided with transparent properties so that light is 5 emitted. Preferably, side walls 23 also include transparent portions for the emission of light. LED 51 is attached to a battery 52 housed within shaft portion 56. The LED 51 and the optic light are used with a small watch battery, and last a long time, so battery life does not become a concern. The LED 51 (or fiber optic light) may be turned on by rotating the interchangeable attachment and thereby closing a circuit. Or the LED may 10 be turned on via motion sensor or by way of a light sensor so that the light is not turned on unless there is motion or it is dark out, thereby saving the battery life.
Alternatively, the show surface 22 of the interchangeable attachment 20 may include reflective properties. This has significant application when as applied to a child's back pack or bag, or a pet's collar and/or leash, in order to impart an added measure of 1 5 safety to the child and/or pet, respectively. Preferably, reflectivity is provided by the incorporation of retroreflective corner cube reflectors or microsphere reflective elements thermally bonded onto a strip that is bonded onto the top side 21 of the interchangeable attachment 20 to yield a reflective show surface 22 thereto.
Preferably, reflectivity is provided via a plurality of glass reflective elements or 20 beads bond to the show surface 22 so that the a large portion of light emitted from a light source is reflected back to the light source such that the pathway for the angle of reflection of the light is substantially the same as the pathway for the angle of incidence. With this structure, the show surface 22 reflects a significant quantum of the incident light from a car head light or other light emitting element back to the source. Reflectivity may be provided via corner cube prismatic or microsphere geometry bonded onto the show surface 22. These transparent retroreflective elements may be made from high refractive index transparent materials such as barium oxide-titanium oxide containing glasses. They exhibit a refractive index in the range of 1.9 to 2.2. Preferably, abrasion resistance properties are provided to the reflective show surface 22 by applying a transparent coating onto the show surface 22 of the interchangeable attachment 20. One such coating comprises a polymer that is transparent, flexible and has a refractive index significantly smaller than that of the retroreflective elements used. For example, thermosetting resin compositions such as two-component polyurethane may be painted or sprayed over the reflective show surface 22. Thermoplastic aliphatic thermoplastic polyurethanes are preferred as compared to aromatic urethanes because of their transparency, resistance to dirt build-up, flexibility ultraviolet radiation degradation resistance. Typically, aliphatic polyurethane has the structure
[—O—(CH(CH3)CH2O20—C(O)—NH—R—NH—C(O)—]; or
[—O—(CH2—CH2CH2CH2—O—)10—C(O)—NH—R—NH—C(O)—], where R is a non-aromatic group. The thickness of the transparent abrasion resistant coating is in the range of 0.002 to 0.010 inches. The coating has a refractive index significantly lesser than that of retroreflective elements bonded to the reflective strip bond to the show surface 22 of the interchangeable attachment 20. Typically the retroreflective elements have a refractive index of 1.9 to 2.2 and the flexible transparent abrasion resistant polymeric coating has a refractive index of 1.3 to 1.55. A 0.002 to 0.010 inch layer of transparent flexible abrasion resistant polymeric coating does not affect the path of normally incident incoming light beam. With such a coating alteration of the path of inclined incident light beam is minimal. Similarly, the reflected light beam path is not severely affected. The internal reflection property of the retroreflective elements is not deteriorated since the abrasion resistant coating has significantly lower refractive index, as compared to that of the retroreflective elements.
