Belt Clamp

Abstract

A belt clamp is disclosed in which, for example, a pair of anti-slipping portions are arranged on a front surface (a surface provided with a toothed portion) at both ends in width direction of a belt body of a belt of the belt clamp. The pair of anti-slipping portions are disposed at a portion of a distal end of the belt body not having a toothed portion and so as not to overlap with the toothed portion in the width direction.

1 . A belt clamp comprising:
 an elongated strap-shaped belt having a flexibility capable of being wound around an outer circumferential surface of an object to be clamped;   a buckle disposed at a base end of the belt and having a belt insertion hole for allowing insertion of the belt therethrough;   a locking portion projecting toward a front surface of the belt inserted into the belt insertion hole; and   a locked portion disposed on the front surface of the belt confronting the locking portion,   the locking portion being disposed confronting part of the front surface of the belt, the locked portion being aligned on the front surface of the belt along a longitudinal direction thereof,   near a tip of the belt extended from a region not having the locked portion on the front surface of the belt, an anti-slipping portion formed from alternate concaves and convexes being arranged in rows on the front surface of the belt along the longitudinal direction thereof.   
     
     
         2 . The belt clamp of  claim 1 , wherein
 at least two ridges extending along the longitudinal direction of the belt are formed at a predetermined interval on the front surface of the belt, the locked portion aligned being disposed in a row at a width of the interval between the ridges and inside the ridges along the belt longitudinal direction, and wherein   in a belt region having the ridges thereon but not having the locked portion aligned, the ridges are formed with alternate concaves and convexes so that the ridges have a difference in height along the belt longitudinal direction, the concaves and convexes of the ridges functioning as the anti-slipping portion when the belt region is grasped.   
     
     
         3 . The belt clamp of  claim 1 , wherein
 the locked portion is disposed at a central portion in a width direction crossing to the longitudinal direction of the belt, and wherein   the anti-slipping portion is disposed at both ends of the belt in the width direction thereof and at portions not overlapping with the locked portion.   
     
     
         4 . The belt clamp of  claim 1 , wherein
 the anti-slipping portion is formed from a convexed portion and a concaved portion alternately disposed along the longitudinal direction of the belt, the convexed portion having a top surface coplanar with the front surface of the belt, the concaved portion having a bottom notched from the front surface of the belt in the direction of thickness.   
     
     
         5 . The belt clamp of  claim 4 , wherein
 a wall surface of the anti-slipping portion toward at least the base end of the belt is slanted or curved in front view of the belt.   
     
     
         6 . The belt clamp of  claim 4 , wherein
 a wall surface of the anti-slipping portion toward at least the base end of the belt is slanted or curved with respect to the longitudinal direction of the belt in side view of the belt.   
     
     
         7 . The belt clamp of  claim 4 , wherein
 length of the concaved portion of the anti-slipping portion in the longitudinal direction of the belt is greater than length of the convexed portion of the anti-slipping portion in the same direction.   
     
     
         8 . The belt clamp of  claim 2 , wherein
 the locked portion is disposed at a central portion in a width direction crossing to the longitudinal direction of the belt, and wherein   the anti-slipping portion is disposed at both ends of the belt in the width direction thereof and at portions not overlapping with the locked portion.   
     
     
         9 . The belt clamp of  claim 2 , wherein
 the anti-slipping portion is formed from a convexed portion and a concaved portion alternately disposed along the longitudinal direction of the belt, the convexed portion having a top surface coplanar with the front surface of the belt, the concaved portion having a bottom notched from the front surface of the belt in the direction of thickness.   
     
     
         10 . The belt clamp of  claim 3 , wherein
 the anti-slipping portion is formed from a convexed portion and a concaved portion alternately disposed along the longitudinal direction of the belt, the convexed portion having a top surface coplanar with the front surface of the belt, the concaved portion having a bottom notched from the front surface of the belt in the direction of thickness.   
     
     
         11 . The belt clamp of  claim 5 , wherein
 length of the concaved portion of the anti-slipping portion in the longitudinal direction of the belt is greater than length of the convexed portion of the anti-slipping portion in the same direction.   
     
     
         12 . The belt clamp of  claim 6 , wherein
 length of the concaved portion of the anti-slipping portion in the longitudinal direction of the belt is greater than length of the convexed portion of the anti-slipping portion in the same direction.
