Securing device for combining floor boards

Abstract

A securing device has a base with two longitudinal sides, an extended tongue, a rib, two buffers and at least one pin. The extended tongue is formed on one of the longitudinal sides on the top surface and has a first mounting groove defined in the inner surface of the extended tongue. The rib is formed on the top surface of the base to form a receiving recess between the extended tongue and the rib. The rib is aligned with the extended tongue and has a second mounting groove. The at least one hole is defined in the base at the other longitudinal side. The two buffers are respectively mounted in the first mounting groove and the second mounting groove. The buffer mounted in the second mounting groove has a diameter larger than that of the other buffer. The at least one pin is mounted respectively in the at least one hole. With the two buffers, the noise caused from piecing the floor boards will be reduced.

1 . A securing device for combining floor boards comprising:
 a base having two longitudinal sides and a top surface,   an extended tongue formed on one of the longitudinal sides on the top surface of the base and having
 an inner surface, and 
 a first mounting groove defined in the inner surface of the extended tongue, 
   a rib formed on the top surface of the base and aligned with the extended tongue to form a receiving recess between the extended tongue and the rib, and having a second mounting groove,   at least one hole defined in the base at the other longitudinal side,   two buffers respectively mounted in the first mounting groove and the second mounting groove, wherein the buffer mounted in the second mounting groove has a diameter larger than that of the buffer mounted in the first mounting groove for defining a gap between the side surface of the rib and a tongue of a floor plate when the floor plate is combined with the securing device so as to allow an expansion or contraction of adjacent floor boards due to weather change; and   at least one pin mounted respectively in the at least one hole.   
   
   
       2 . The securing device as claimed in  claim 1 , wherein the rib is formed away from the center of the base. 
   
   
       3 . The securing device as claimed in  claim 2 , wherein the cross-section of each mounting groove is semi-circular. 
   
   
       4 . The securing device as claimed in  claim 3 , wherein each buffer is made of rubber. 
   
   
       5 . The securing device as claimed in  claim 3 , wherein each buffer is made of ethylene vinyl acetate. 
   
   
       6 . The securing device as claimed in  claim 1 , wherein the cross-section of each mounting groove is semi-circular. 
   
   
       7 . The securing device as claimed in  claim 1 , wherein each buffer is made of rubber. 
   
   
       8 . The securing device as claimed in  claim 1 , wherein each buffer is made of ethylene vinyl acetate.
