A spring compressor comprising an actuator with a body and a rod that are telescopically movable relative to each other and two jaws each comprising an attachment portion (2) for attachment to the actuator and a working portion (3) for engaging a turn of a helical spring (8, 9), the working portion (3) of each jaw comprising a first part (4) and a second part (12), one of the parts being connected to the attachment portion (2) and defining a track segment (5) for bearing against a portion of a spring turn, and the other part forming an arm (12) hinged to the attachment portion (2) or to the first part (4) in the vicinity of one end (5c) of the track segment (5) about an axis (11) that is substantially perpendicular to the surface of the track segment (5), and forming at its free end a zone for taking charge of a turn of the spring.
A spring compressor comprising an actuator with a body (100) and a rod (110) that are telescopically movable relative to each other, and two jaws (1, 1′) each comprising an attachment portion (2) for attachment to the actuator and a working portion (3) for engaging a turn of a helical spring (8, 9), in which the working portion (3) of each jaw comprises a first part (4) and a second part (12) that are hinged relative to each other, the first part (4) being connected to the attachment portion (2), wherein the first part (4) carries, close to said attachment portion, a circular track segment (5) for bearing against a portion of a spring turn, provided along its inside edge with a rim (7) for retaining the turn, and wherein the second part is in the form of an arm (12) hinged to the attachment portion (2) or to the first part (4) in the vicinity of one end (5c) of the track segment (5) about an axis (11) that is substantially perpendicular to the surface of the track segment (5), and whose free end forms a zone for taking charge of a turn of the spring, wherein the track segment (5) has a free end (5a) opposed to said one end (5c), a width of said free end (5a) increasing towards said one end (5c).
A spring compressor comprising an actuator with a body (100) and a rod (110) that are telescopically movable relative to each other, and two jaws (1, 1′) each comprising an attachment portion (2) for attachment to the actuator and a working portion (3) for engaging a turn of a helical spring (8, 9), in which the working portion (3) of each jaw comprises a first part (4) and a second part (12) that are hinged relative to each other, the first part (4) being connected to the attachment portion (2), wherein the first part (4) carries, close to said attachment portion, a circular track segment (5) for bearing against a portion of a spring turn, provided along its inside edge with a rim (7) for retaining the turn, and wherein the second part is in the form of an arm (12) hinged to the attachment portion (2) or to the first part (4) in the vicinity of one end (5c) of the track segment (5) about an axis (11) that is substantially perpendicular to the surface of the track segment (5), and whose free end forms a zone for taking charge of a turn of the spring, wherein the connection between the working portion (3) and the attachment portion (2) includes a pivot (25, 26a) substantially parallel to the surface of the track (5) and passing substantially through the center of the attachment portion (2).
A spring compressor comprising an actuator with a body (100) and a rod (110) that are telescopically movable relative to each other, and two jaws (1, 1′) each comprising an attachment portion (2) for attachment to the actuator and a working portion (3) for engaging a turn of a helical spring (8, 9), in which the working portion (3) of each jaw comprises a first part (4) and a second part (12) that are hinged relative to each other, the first part (4) being connected to the attachment portion (2), wherein the first part (4) carries, close to said attachment portion, a circular track segment (5) for bearing against a portion of a spring turn, provided along its inside edge with a rim (7) for retaining the turn, and wherein the second part is in the form of an arm (12) hinged to the attachment portion (2) or to the first part (4) in the vicinity of one end (5c) of the track segment (5) about an axis (11) that is substantially perpendicular to the surface of the track segment (5), and whose free end forms a zone for taking charge of a turn of the spring, wherein the attachment portion (2) of each jaw is in the form of a sleeve (20) connected sideways to the working portion (3), the central recess (21) being U-shaped and open sideways away from the working portion (3), and having at least one longitudinal end situated beside the rear face of the jaw that is provided with a countersunk area (22) of diameter greater than the width of the recess (21) in the U-shape.
A spring compressor, comprising:
A spring compressor comprising an actuator with a body (100) and a rod (110) that are telescopically movable relative to each other, and two jaws (1, 1′) each comprising an attachment portion (2) for attachment to the actuator and a working portion (3) for engaging a turn of a helical spring (8, 9), in which the working portion (3) of each jaw comprises a first part (4) and a second part (12) that are hinged relative to each other, the first part (4) being connected to the attachment portion (2), wherein the first part (4) carries, close to said attachment portion, a circular track segment (5) for bearing against a portion of a spring turn, provided along its inside edge with a rim (7) for retaining the turn, and wherein the second part is in the form of an arm (12) hinged to the attachment portion (2) or to the first part (4) in the vicinity of one end (5c) of the track segment (5) about an axis (11) that is substantially perpendicular to the surface of the track segment (5), and whose free end forms a zone for taking charge of a turn of the spring, wherein one distal end of said circular track segment comprises a tab overlying a surface of said circular track segment.
