Abstract
A car-mat fastener for removably securing a car-mat to a car carpet includes a latching post member, a bottom latching ring-mat member, and a top latching ring-mat member. The top member is telescoped into the bottom member for permanently securing them together and to form an eyelet extending therethrough. The post member includes a lower projecting portion for fixed attachment to the car carpet and an upper post portion for insertion through the eyelet so as to be detachably engaged with the top and bottom latching members.
Claims20
A car-mat fastener for removably retaining a car-mat to a car carpet, said fastener comprising:
- a latching post member consisting of a central flange separating an upper bifurcated post portion and a lower projecting portion, said lower projecting portion being adapted for fixed attachment to a car carpet, said post portion having a slightly enlarged head portion formed with an outer arcuate ridge;
- a bottom latching ring-mat member consisting of a first bifurcated tubular-shaped section and a lower annular flange, said bottom latching member having a first axial opening for receiving a top latching ring-mat member, said first tubular-shaped section having diametrically opposed U-shaped slots and a pair of opposed tabs, said opposed tabs being formed on an inner surface of said first tubular-shaped section and being disposed perpendicularly to said U-shaped slots;
- said top latching ring-mat member consisting of a second tubular-shaped section and an upper annular flange, said top latching member having an axial opening extending therethrough, said axial opening including a first aperture formed in said second tubular-shaped section and a second aperture formed in said upper annular flange defining a radial shoulder therebetween, said second tubular-shaped section having diametrically opposed raised ribs extending longitudinally on its outer surface, said top latching member having a pair of opposed L-shaped cut-outs disposed perpendicularly to said raised ribs;
- said second tubular-shaped section of said top latching member being telescoped into the first axial opening in the first tubular-shaped section of said bottom latching member so that said raised ribs mate with said U-shaped slots and said tabs are permanently secured into said L-shaped cut-outs, said top and bottom latching members sandwiching the car-mat between the upper and lower flanges and forming an eyelet therebetween;
- and
- said post portion of said latching post member being inserted into said eyelet so as to cause the opposed sides thereof to be compressed by said second tubular-shaped section of said top latching member, said head portion being passed through the first aperture so that the arcuate ridge is allowed to become detachably engaged with said radial shoulder formed adjacent the second aperture.

- said second tubular section of said top latching member being telescoped into the first axial opening in the first tubular section of said bottom latching member so that said tabs are permanently secured into said L-shaped cut-outs, said top and bottom latching members sandwiching the car-mat between the upper and lower flanges and forming an eyelet therebetween;
- and
- said post position of said latching post member being inserted into said eyelet so as to cause the opposed sides thereof to be compressed by said second tubular-shaped section of said top latching member, said head portion being passed through the first aperture so that the arcuate ridge is allowed to become detachably engaged with said radial shoulder formed adjacent the second aperture.

A car-mat fastener for removably securing a car-mat to a car carpet, said fastener comprising:
- ring-mat means formed of an upper member and a lower member for sandwiching a car-mat therebetween;
- said upper member including an upper flange portion and a dependent tubular body portion fixed to an undersurface portion of said upper flange portion;
- said lower member including a lower flange portion and an upstanding tubular body portion fixed to an upper surface portion of said lower flange portion;
- means defined upon said upper and lower members for lockingly engaging said upper and lower members together wherein said dependent tubular body portion of said upper member is disposed within said upstanding tubular body portion of said lower member so as to form an eyelet assembly, and wherein said undersurface portion of said upper flange portion of said upper member is disposed so as to be engaged with an upper surface portion of said car-mat while said upper surface portion of said lower flange portion of said lower member is disposed so as to be engaged with an undersurface portion of said car-mat;
- post member means formed of a lower projecting portion for fixed attachment to said car carpet and an upper post portion for insertion through said eyelet assembly of said upper and lower members;
- and
- means defined upon said upper post portion of said post member means and said eyelet assembly for detachably engaging said post member means with said eyelet assembly.
