Quick assembling and disassembling device

A device for the quick assembly and disassembly of two parts, comprising:

• a clasp adapted to be secured to a first of said two parts, said clasp comprising a guide yoke with a guide slot oriented in a first direction, a retaining yoke having a retaining slot, and blocking means, said retaining yoke being mounted so that it can be pivoted at will on said guide yoke;
• and
• a fastener adapted to be secured to a second of said two parts and arranged transversely with respect to said first direction, said fastener simultaneously entering said guide and retaining slots when said clasp is in an open configuration by initial movement in the first direction towards a closed end of said guide slot and with further movement of the fastener into the clasp causing said retaining yoke to pivot between an unlocked position which corresponds to a clasp-open configuration in which said retaining slot is oriented at an angle to said first direction to a locked position which corresponds to a clasp-closed configuration in which said retaining slot is oriented transversely with respect to said first direction, said blocking means spontaneously allowing said clasp to pass from said open configuration to said closed configuration while selectively allowing passage of said clasp from said closed configuration to said open configuration, characterized in that said blocking means comprise at least a first lug borne by a first of said two yokes and projecting towards a second of said two yokes, and at least one corresponding housing located in said second of said two yokes for housing said first lug, a lack of engagement of the first lug in the corresponding housing causing an elastic deformation in at least one of said two yokes, said elastic deformation being taken back upon the engagement of said first lug in said corresponding housing, said first lug being engaged in said corresponding housing only in said clasp-closed configuration, said retaining yoke being mounted to pivot about a pivot supported by said guide yoke, said guide yoke comprises first and second parallel cheeks which are joined together, and said first lug and said corresponding housing are located on said cheeks which face each other and are part of said two yokes, said retaining yoke being mounted inside of said guide yoke and said cheeks of said retaining yoke having legs which extend beyond said guide yoke in said clasp-closed configuration, said cheeks of said retaining yoke moving closer together by squeezing in order that each lug may be disengage from said corresponding housing, said retaining yoke having an elastic tongue which is arranged between said first and second cheeks of said retaining yoke, said elastic tongue being at right angles to said first and second cheeks, said elastic tongue elastically urging said fastener towards said closed end of said guide slot in said clasp-closed configuration.

A device for the quick assembly and disassembly of two parts, comprising:

• a clasp adapted to be secured to a first of said two parts, said clasp comprising a guide yoke with a guide slot oriented in a first direction, a retaining yoke having a retaining slot, and blocking means, said retaining yoke being mounted so that it can be pivoted at will on said guide yoke;
• and
• a fastener adapted to be secured to a second of said two parts and arranged transversely with respect to said first direction, said fastener simultaneously entering said guide and retaining slots when said clasp is in an open configuration by initial movement in the first direction towards a closed end of said guide slot and with further movement of the fastener into the clasp causing said retaining yoke to pivot between an unlocked position which corresponds to a clasp-open configuration in which said retaining slot is oriented at an angle to said first direction to a locked position which corresponds to a clasp-closed configuration in which said retaining slot is oriented transversely with respect to said first direction, said blocking means spontaneously allowing said clasp to pass from said open configuration to said closed configuration while selectively allowing passage of said clasp from said closed configuration to said open configuration, characterized in that said blocking means comprise at least a first lug borne by a first of said two yokes and projecting towards a second of said two yokes, and at least one corresponding housing located in said second of said two yokes for housing said first lug, a lack of engagement of the first lug in the corresponding housing causing an elastic deformation in at least one of said two yokes, said elastic deformation being taken back upon the engagement of said first lug in said corresponding housing, said first lug being engaged in said corresponding housing only in said clasp-closed configuration, said retaining yoke being mounted to pivot about a pivot supported by said guide yoke, said guide yoke comprises first and second parallel cheeks which are joined together, and said first lug and said corresponding housing are located on said cheeks which face each other and are part of said two yokes, said retaining yoke being mounted inside of said guide yoke and said cheeks of said retaining yoke having legs which extend beyond said guide yoke in said clasp-closed configuration, said cheeks of said retaining yoke moving closer together by squeezing in order that each lug may be disengage from said corresponding housing, said first lug having a sloping profile which ends in an abrupt edge, said abrupt edge being the last to enter said housing when said first lug is engaged in said corresponding housing through the rotation of said retaining yoke from a unlocked position into a locked position.

In combination device for the quick assembly and disassembly of a rod which operates a braking system and a brake pedal, the combination comprising:

• a clasp secured to said rod, said clasp comprising a guide yoke with a guide slot oriented in a first direction, a retaining yoke having a retaining slot, said retaining yoke being mounted so that it can be pivoted at will on said guide yoke;
• a fastener including a spindle fixed to the brake pedal and arranged transversely with respect to said first direction, said spindle simultaneously entering said guide and retaining slots when said clasp is in an open configuration by initial movement in the first direction towards a closed end of said guide slot and with further movement of the spindle into the clasp causing said retaining yoke to pivot between an unlocked position which corresponds to a clasp-open configuration in which said retaining slot is oriented at an angle to said first direction to a locked position which corresponds to a clasp-closed configuration in which said retaining slot is oriented transversely with respect to said first direction;
• and
• blocking means for spontaneously allowing said clasp to pass from said open configuration to said closed configuration while selectively allowing release of said clasp from said closed configuration to said open configuration, characterized in that said blocking means comprise at least a first lug borne by a first of said guide and retaining yokes and projecting towards a second of said guide and retaining yokes, and at least one corresponding housing located in said second of said guide and retaining yokes for housing said first lug, a lack of engagement of the first lug in the corresponding housing causing an elastic deformation in at least one of said guide and retaining yokes, said elastic deformation being taken back upon the engagement of said first lug in said corresponding housing, said first lug being engaged in said corresponding housing only in said clasp-closed configuration, said retaining yoke being mounted to pivot about a pivot supported by said guide yoke, said guide yoke comprises first and second parallel cheeks which are joined together, and said first lug and said corresponding housing are located on cheeks which face each other and are part of said two yokes, said retaining yoke being mounted inside of said guide yoke and said cheeks of said retaining yoke having legs which extend beyond said guide yoke in said clasp-closed configuration, said cheeks of said retaining yoke moving closer together by squeezing in order that each lug may be disengage from said corresponding housing.
