Securing tool

Abstract

The present invention relates to a base body ( 10 ) fixed to a first belt ( 4 A) and a securing body ( 30 ) fixed to a second belt ( 4 B) so as to be rotatable relative to the base body ( 10 ). The base body ( 10 ) is provided with a securing body ( 16 ), while the securing body ( 30 ) is provided with a securing claw ( 42 ) capable of being engaged with and disengaged from the securing portion ( 16 ). The base body ( 10 ) is provided with an elastically deformable portion ( 18 ) capable of being elastically deformed in a direction to bring the securing portions ( 16 ) and the securing claw ( 42 ) into a firmer engagement when a load is applied in a predetermined direction.

1 . A securing tool for securing a second member to a first member, the securing tool receiving a load in a predetermined direction when being in a secured state, comprising: 
 a base body fixed to the first member; and    a securing body fixed to the second member so as to be rotatable relative to the base body, wherein    one of the base body and the securing body includes a securing portion,    the other of the base body and the securing body includes a securing claw engageable with the securing portion, and    at least one of the base body and the securing body includes an elastically deformable portion to be elastically deformed in a direction to bring the securing portion and the securing claw into a firmer engagement when the load is applied in the predetermined direction.    
   
   
       2 . A securing tool for securing a second member to a first member, the securing tool receiving a load in a predetermined direction when being in a secured state, comprising: 
 a base body fixed to the first member;    and a securing body fixed to the second member so as to be rotatable relative to the base body, wherein    one of the base body and the securing body is formed as a frame having: lateral walls on both sides; and connecting bars respectively connecting respective pairs of facing end sides of the lateral walls,    the frame has: a rotation guide provided on one end side of the lateral walls; a fixing portion provided on the other end side of the lateral walls and fixed to the first member; and a securing portion provided between the lateral walls at a section between the rotation guide and the fixing portion,    the other of the base body and the securing body includes a securing claw engageable with the securing portion, and    the lateral walls of the frame have an elastically deformable portion to be elastically deformed in a direction to bring the securing portion and the securing claw into a firmer engagement when the load is applied in the predetermined direction.    
   
   
       3 . The securing tool according to  claim 2 , wherein 
 the securing portion has a pair of securing pieces that inwardly project from the frame toward each other, the securing pieces having, between tip ends thereof, an insertion gap for the securing claw to be inserted.    
   
   
       4 . The securing tool according to  claim 2 , wherein 
 the securing portion has: first securing portions formed on respective tip ends of the pair of securing pieces; and second securing portions formed along respective side edges of the pair of securing pieces, and    the securing claw has: a first securing claw engageable with the first securing portions; and a second securing claw elastically engageable with the second securing portions.    
   
   
       5 . The securing tool according to  claim 2 , wherein 
 the second securing claw is provided to the other of the base body and the securing body so as to project in a width direction, and    the first securing claw is provided to the second securing claw at a substantially middle position in the width direction.    
   
   
       6 . The securing tool according to  claim 2 , wherein 
 the elastically deformable portion has slits defined in the respective lateral walls of the frame.    
   
   
       7 . A securing tool for securing a second member to a first member, the securing tool receiving a load in a predetermined direction when being in a secured state, comprising: 
 a base body fixed to the first member; and    a securing body fixed to the second member so as to be rotatable relative to the base body, wherein    one of the base body and the securing body includes a third securing portion and a fourth securing portion that are spaced apart from each other in the predetermined direction,    the other of the base body and the securing body includes a securing claw engageable with the third securing portion, and    at least one elastically deformable portion is provided between the third securing portion and the one of the base body and the securing body, the elastically deformable portion allowing the third securing portion to be displaced and elastically deformed in a direction that brings the fourth securing portion into a firmer engagement with the securing claw when the load is applied in the predetermined direction.    
   
   
       8 . The securing tool according to  claim 7 , wherein 
 the one of the base body and the securing body is formed as a frame having: lateral walls on both sides; and connecting bars respectively connecting respective pairs of facing end sides of the lateral walls,    the frame has: a rotation guide for guiding a rotation of the other of the base body and the securing body, the rotation guide being provided on one end side of the lateral walls; a fixing portion provided on the other end side of the lateral walls and fixed to the first member; and a third securing portion and a fourth securing portion provided between the lateral walls at a section between the rotation guide and the fixing portion,    the fourth securing portion has a pair of securing pieces that inwardly project from the lateral walls toward each other, the securing pieces having a space between tip ends thereof,    the third securing portion projects inwardly from the lateral walls toward each other and has a securing projection at a middle portion thereof, the securing projection being inserted in the space, and    the elastically deformable portion is formed in ranges from the respective lateral walls to the securing projection of the third securing portion.
