Claims (12)

A return spring device for a door handle, which is external to the locking body, for installation on the spindle of a door handle, which device comprises a body part (1) with throttling elements (2) for a spring, a spring casing (3) with throttling surfaces (4 ) for a cap, which casing can be rotatably attached relative to the body part (1), and a return spring (5), which can be installed in the space between the body part (1) and the spring casing (3), the ends of the spring being arranged to act together with the throttling elements (2) and the throttling surfaces (4) during installation, characterized in that the body part (1) comprises a mounting body (6) and a limiting plate (7) which can be rotatably arranged relative to each other and which comprises a rotation-limiting element ( 8A, 8B), which limits the rotation of the mounting body (6) and the limiting plate (7) relative to each other, which limiting plate (7) also comprises the throttling elements (2), whereby the rotation-limiting element (8A, 8B) when r the return spring device is installed and the handle is in its normal position, prevents rotation of the limiter plate (7) in a first direction relative to the mounting body (6), whereby rotation of the handle in the first direction is prevented by the return spring (5), and allows the limiter plate (7 ) to rotate in a different direction relative to the mounting body (6), thereby making it possible to rotate the handle in the other direction without being counteracted by the return spring. Device according to claim 1, characterized in that when the return spring device is installed and the handle is rotated from the normal position to the locking position, the rotation limiting element {8A, 8B) allows the handle to be rotated in the first direction to the normal position of the handle without being counteracted. of the return spring (5). Device according to claim 2, characterized in that the rotation-limiting element (8A, 8B) comprises a throttle projection (8A) in the limiter plate (7) and a curved, longitudinal recess (8B) in the mounting body (6), which recess (8B) has two ends (9A, 9B) and allows the throttle projection (8a) to be inserted into the recess, thereby preventing the restrictor plate (7) when the throttle projection is against one of the ends (9A, 9B) from rotating in the first direction, but allowing turn in the other direction. Device according to claim 2, characterized in that the rotation-limiting element (6A, 6B) comprises a throttle projection (8A) in the mounting body (6) and a curved, longitudinal recess (8B) in the limiter plate (7); wherein the recess (8B) has two ends (9A, 9B) and allows the throttle projection (8A) to be inserted into the recess, whereby the limiting plate (7), when the throttle projection abuts against one of the ends (9A, 9b), is prevented from rotating in the first direction, but is allowed to turn in the second direction. Device according to claim 3 or 4, characterized in that it is arranged to be equally suitable for left- and right-handed handle installations, the handiness of the installation depending on the specific end (9A, 9B) of the recess (8B), as the throttle projection (8A) rests on in the normal position of the handle; where the recess (8B) allows rotation of the handle from the normal position to the locking position without being counteracted by the return spring (5) regardless of the handling of the installation. Device according to any one of claims 1 to 5, characterized in that the limiting plate (7) comprises at least one position-specific marker (10) for indicating the position of the handle. Device according to claim 6, characterized in that it is arranged for installation below a cover plate (15), which has an opening so that the opening (16) in the cover plate makes the marker (10) visible when the handle is in the position indicated by the cursor, Device according to any one of claims 1 to 7, characterized in that the mounting body (6) contains openings (20) and the limiting plate (7) contains cut-outs (21) or holes for fastening screws (18). Device according to any one of claims 1 to 6, characterized in that it is arranged for installation below a cover plate (14). Device according to claim 9, characterized in that the mounting body (6) contains openings (20) and the limiting plate (7) contains cut-outs (21) or holes for fastening screws (18). Device according to any one of claims 7 to 10, characterized in that the edges of the mounting body (6) are grooved in order to increase the contact between the cover plate and the mounting body (6). Device according to any one of claims 1 to 11, characterized in that the joint between the body part (1) and the spring cap (3) is a snap joint,
