According to an embodiment, the main portion 38, the engaging inwardly curved portion 40 and the end portion 42 may be made from the same piece of material and form a single unitary part.
According to an embodiment, the substantially flexible second attachment member 34 may be rotatably extending from and relative to the second end 30 of the second clasp portion 26. Thus, the main portion 38 may rotatably extend from the second end 30 of the second clasp portion 26 via a nail, a screw, a bent portion of the main portion 38 and/or a connection of any other suitable configuration that would allow the main portion 38 to rotate about the longitudinal axis (not shown) defined by the second clasp portion (see arrow 100 on
According to an embodiment, the same unitary piece of material includes steel, stainless steel, silver, gold, and/or any other suitable material.
As shown in
According to an embodiment, the male clasp portion 20 and the female clasp portion 26 may be of any suitable shape and/or configuration such as to releasably connect together. For example, the male clasp portion 20 and the female clasp portion 26 may be, without limitation, of a cylindrical configuration (as shown), of a rounded or spherical configuration, of a prismatic configuration, and the like.
According to an embodiment, the male and the female clasp portions 20, 26 may define together a length (not shown) which is about less than 20 mm. More preferably, the male and the female clasp portions 20, 26 may define a length which is about 14 mm.
According to an embodiment, the necklace 10 may define a length which is about less than 15 inches, which includes the main chain 12 with the clasp device 18 (which includes the female and male clasp portions 20, 26). More particularly, the necklace 10 may define a length which is about 11-13 inches (11 inches may be for 0-2 years-old—13 inches may be for 2-4 years old). It is also to be mentioned that the necklace 10 may have a longer length (i.e., a necklace 10 could be worn by an adult). The necklace 10, that can be worn by an adult, would also need to include parts that are releasably detachable (i.e., allowing the creation of gap 36 between the end portion 42 and the main portion 38 for allowing the main chain 12 to be released from the substantially flexible second attachment member 34) in order to obtain one detached necklace 10 in a single part after tension have been imparted on one or another part of the necklace 10.
According to an embodiment, the ring portion 52 of the first attachment member 32 may define a diameter of about less than 4 mm. More particularly, the ring portion 52 of the first attachment member 32 may define a diameter of about 2.5 mm.
According to an embodiment, the hook-like portion defined by the main portion 38, the engaging inwardly curved portion 40 and the end portion 42 together may define a diameter of about less than 5 mm.

According to an embodiment, the sufficient tension may be determined based on the different regulations and/or norms established by different countries, institutions, organizations and the like. For example, the sufficient tension may be about 15 pounds and over. Thus, in use, a child under a certain age may wear a necklace 10. Upon interaction between the necklace 10 of the child and an element from the external environment, which may include, without limitation, a bed part, a house part (i.e., a table, a chair, a countertop, a kitchen element, a hook, a fence), a toy, another person, and the like, the second attachment 34 of the female clasp portion 26 will substantially open (i.e., a gap 36 is created about the substantially flexible second attachment member 34 allowing the main chain 12 to be released from the substantially flexible second attachment member 34 as at least the main portion 38, the engaging inwardly curved portion 40 and the end portion 42 are flexible and/or resilient) to release the second end 16 (i.e., second loop 21) of the main chain 12. According to this configuration and the fact that the substantially flexible second attachment member 34 opens from a normally closed position (
The present invention will be more readily understood by referring to the following examples which are given to illustrate the invention rather than to limit its scope.
In 2014, a testing company received an 11-inch necklace 10 for testing purposes.
Some tests were performed. A breakaway tension test, as per ASTM F2923-11, section 12.2 for determination of breakaway features and releases was performed. A use and abuse test, as per ASTM F2923-11, Section 12.3 for determination of potential hazards that would result from the normal use or reasonably foreseeable damage or abuse intended for children of young ages.
Test Results—Breakaway Tension Test
The 11-inch necklace 10 was tested in accordance with ASTM F2923-11, Section 12.2 to address potential hazards associated with children's jewelry attached around the neck of a child, which may catch on objects in the child's environment resulting in strangulation. The test setup was performed under a maximum load of 1 kN and a maximum torque of 3.5 Nm at ambient temperature. The results obtained shows that the necklace 10 intended to be attached around the neck released, either by designed breakaway feature, attachment design or physical properties of the material used, when subjected to 15 pounds of tension in accordance with the breakaway tension test. The results obtained further shows that no hazardous sharp points or hazardous sharp edges were observed during the tension test.
Test Results—Use and Abuse Test
For this particular test, the parameters were as follows:
Impact Test—Age of 18 months or less: Impact medium;
Torque Test—Age of 18 months or less: Torque Wrench and standard torque test clamp;
Tension test—Age of 18 months or less: Digital Force Gauge and long nose vise grip; and
Compression test—Age of 18 months or less: Digital Force Gauge and compression disc.
The results obtained shows that the necklace 10 has no accessible, potentially hazardous sharp points before or after use and abuse test and that the necklace 10 has no accessible, potentially hazardous projections before or after use and abuse test.
