Removable hat accessory

Abstract

An attaching device for removably attaching various types of display objects to a hat. The attaching device has a fastener for engaging with the display object and a spring member for retaining the fastener therein and attaching to a button of the hat. The fastener is in the form of a plastic ring with a plurality of tabs projecting from a bottom rim thereof. The spring member has an upper spring portion, a lower spring portion and a joint spring portion connecting the upper and lower spring portions. The upper spring portion has an inner perimeter substantially the same as the maximum radial extent of the tabs, such that the plastic ring can be inserted therein. A plurality of protrusions is formed to extend inwardly from the inner perimeter of the upper spring portion. The protrusions are outline with a profile mating that of the tabs, such that the plastic ring can be secured interlocked with the spring member. The lower spring portion has an open end split into two parallel leaves, such that, by bending the joint spring to open the space between the upper and lower spring portions, the spring member can slide towards the button to receive the button within the space between the upper and lower spring portions.

1 . An attaching device for attaching an object to a button of a hat, comprising:
 a fastener, comprising:
 a fastening ring to be engaged with the object; and 
 a plurality of tabs projecting radially from a bottom rim of the fastening ring, wherein each of the tabs has a recessed central portion; and 
   a spring member for removably attaching to the button of the hat, comprising:
 an upper spring portion encircling the fastening ring therein, the upper spring portion having a plurality of protrusions extending from an inner perimeter thereof, and the protrusions being configured with a profile mating the tabs for interlocking the fastener; 
 a lower spring portion operative to extend under the button of the hat; and 
 a joint spring portion connecting the upper spring portion to lower spring portion. 
   
     
     
         2 . The attaching device of  claim 1 , wherein the fastener further comprises a plurality of fins projecting from a top rim of the fastening ring for attaching the object. 
     
     
         3 . The attaching device of  claim 2 , wherein the fins are formed over spaces between the adjacent tabs. 
     
     
         4 . The attaching device of  claim 3 , wherein the fastener further comprises a circular flange extending from the tabs about a bottom rim of the fastening ring. 
     
     
         5 . The attaching device of  claim 4 , wherein the flange has an outer perimeter larger than that of the upper spring portion. 
     
     
         6 . The attaching device of  claim 1 , wherein the lower spring has a proximal end connected to the joint spring portion and a distal end split into two leaves. 
     
     
         7 . The attaching device of  claim 6 , wherein the leaves are parallel to each other. 
     
     
         8 . The attaching device of  claim 6 , wherein the leaves are terminated with upwardly curved tips. 
     
     
         9 . The attaching device of  claim 1 , wherein the joint spring includes at least one ridges formed thereon for increasing spring strength. 
     
     
         10 . The attaching device of  claim 1 , wherein a vertical distance between the upper spring portion and the lower spring portion is no larger than the button of the hat. 
     
     
         11 . An attaching device for removably attaching a display object to a hat, wherein the display object includes a receiving slot recessed from a bottom surface thereof, and the attaching device comprising an upper spring portion, a lower spring portion having two parallel leaves, and a joint spring portion connecting the upper to the lower spring portions. 
     
     
         12 . The hat accessory of  claim 11 , wherein the object includes two laterally detachable parts and each of the parts has a bottom surface configured with one half of the receiving slot. 
     
     
         13 . A hat accessory, comprising:
 a spring member, comprising:
 an upper spring portion; 
 a lower spring portion underlying the upper spring portion, wherein the lower spring portion has one end split into two parallel leaves and the other end connected to the upper spring portion; and 
 a joint spring portion for connecting the other end of the lower spring portion to one end of the upper spring portion; and 
   a display object comprising two mating parts laterally detachable from each other, wherein each of the mating parts includes a bottom surface configured with a slot for laterally receiving at least a part of the upper spring portion.   
     
     
         14 . The hat accessory of  claim 12 , wherein each of the mating parts further comprises a side surface and a plurality of latching structures protruding from an interior side of the side surface. 
     
     
         15 . The hat accessory of  claim 13 , wherein the latching structures includes a plurality of protruding posts formed in one of the mating parts and a plurality of receiving sleeves formed in the other mating parts.
