Abstract

Disclosed is a detachment type waist protecting belt wherein hook and loop fastener strips are attached to distal ends and heightwise middle portions of left and right bands, a pair of connecting plates made of a soft plastic material are secured to proximal ends of the left and right bands, connection rings are rotatably fastened to the connecting plates by pins to be spaced one from another in a longitudinal direction by a predetermined distance, both ends of a pair of pulling cords respectively pass zigzag from upper and lower ends of the connecting plates through the connection rings so as to be freed at heightwise middle portions of the connecting plates, and a pair of tightening bands are connected to the freed both ends of the pulling cords. The detachment type waist protecting belt includes a waist support which fits a contour of the waist of the human body. Guide projections are formed at both sides of an outer surface of the waist support. The heightwise middle portions of the left and right bands are defined with guide slots which extend in a transverse direction to guide the guide projections, whereby the detachment type waist protecting belt can be equipped with the waist support as occasion arises.

Claims

1. A detachment type waist protecting belt wherein hook and loop fastener strips are attached to distal ends and heightwise middle portions of left and right bands, a pair of connecting plates made of a soft plastic material are secured to proximal ends of the left and right bands, a plurality of connection rings are rotatably fastened to the connecting plates by pins in such a way as to be spaced one from another in a longitudinal direction by a predetermined distance, both ends of a pair of pulling cords respectively pass zigzag from upper and lower ends of the connecting plates through the connection rings so as to be freed at heightwise middle portions of the connecting plates, and a pair of tightening bands are connected to the freed both ends of the pair of pulling cords, characterized in that the detachment type waist protecting belt includes a rigid waist support which has a U-shaped cross-section and which fits a contour of the waist of the human body, guide projections are formed at both sides of an outer surface of the waist support, and the heightwise middle portions of the left and right bands are defined with guide slots which extend in a transverse direction to provide direction for the guide projections, whereby the detachment type waist protecting belt can be equipped with the waist support as occasion arises.

2. The detachment type waist protecting belt as claimed in claim 1, wherein the guide projections are arranged in line along a horizontal direction and each has a head portion and a shaft portion, and circular holes are defined at predetermined locations along the guide slots in a manner such that the head portions of the guide projections are insertable therethrough.

3. The detachment type waist protecting belt as claimed in claim 1, wherein the connecting plates are defined, at places where the connection rings are fastened thereto, with first grooves, a pair of cover members are respectively fastened to the pair of connecting plates and are defined, at places which correspond to the first grooves of the connecting plates, with second grooves, and each first groove and each corresponding second groove cooperate with each other so as to accommodate a portion of the connection ring in a space created therebetween and limit rotation of the connection ring to a predetermined angle;

wherein opposite surfaces of the connecting plates and the cover members have a pitch substantially corresponding to the predetermined distance and thereby are rendered flexible for optimal fitting the contour of the waist of the human body; and

wherein guide rollers each having a circumferential groove are interposed between the connecting plates and the cover members at positions where the ends of the pulling cords are freed through the connecting plates and the cover members, and guide pieces each having a predetermined height are formed on the cover members in a manner such that they guide the freed ends of pulling cords toward the distal ends of the left and right bands.
