Abstract
Abstract A press fastener comprising a plug body connecting with a slotted body. The plug body contains an elastic tongue part for extending into the slotted body. The tongue part contains a climbing angle positioned at the end thereof to hook the plug body to the slotted body when the climbing angle of the tongue part extends along an angled receiving groove of the slotted body, thereby stressing the tongue part, and into a center cavity of the slotted body. The central cavity is of such dimensions to allow a press groove to be supported therein to allow unhooking of the plug body from the slotted body when pressure is exerted thereon.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
150 words
A press fastener, including the combination of: a plug body including outwardly extending elastic tongue part positioned at one end of said plug body, said tongue part containing a climbing angle peak along a front portion thereof; a slotted body including an angled receiving groove extending interiorly from one end of said slotted body to a press groove creating a gap in a central portion thereof for allowing said elastic tongue part to extend through said receiving groove such that said climbing angle peak of the tongue part extends into said press groove to fasten said plug body to said slotted body; and an elastic press body positioned in the press groove of said slotted body supported thereby for allowing downward pressure exerted upon said elastic press body to be transmitted to said climbing angle of the elastic tongue part to thereby unfasten said plug body from said slotted body.
Claim 2
Dependent Claim
150 words
A press fastener, including the combination of: a plug body including outwardly extending elastic tongue part positioned at one end of said plug body, said tongue part containing a climbing angle peak along a front portion thereof; a slotted body including an angled receiving groove extending interiorly from one end of said slotted body to a press groove creating a gap in a central portion thereof for allowing said elastic tongue part to extend through said receiving groove such that said climbing angle peak of the tongue part extends into said press groove to fasten said plug body to said slotted body; and an elastic press body positioned in the press groove of said slotted body supported thereby for allowing downward pressure exerted upon said elastic press body to be transmitted to said climbing angle of the elastic tongue part to thereby unfasten said plug body from said slotted body.
Claim 3
Dependent Claim
36 words
The press fastener of claim 1 further including outwardly extending extenders attached to said elastic press body extending into said slotted body to maintain the orientation of said elastic press body in the elastic press groove.
Claim 4
Dependent Claim
33 words
The press fastener of claim 1 further including slanting bars protruding from said plug body in directions parallel to the lengthwise direction of the elastic tongue part for insertion into said slotted body.
