Abstract
Inner sealing sleeve for inserting into pipes, comprises a sleeve body made of an annularly bent band. An inner band end and an outer band end overlap and the sleeve body can be expanded so that the inner band end can be displaced relative to the outer band end along an expanding direction. A locking arrangement is provided, which prevents the inner band end from being displaceable relative to the outer band end in the direction opposite to the expanding direction. The locking arrangement has a slot arranged on the inner band end in the circumferential direction and has a row of teeth, and a latching mechanism with a latching member. The latching member is acted upon by a spring element and engages in the row of teeth, and the latching member and the spring element are arranged in a chamber of a guide body. The latching member is displaceable in the chamber. The spring element consists of an elastic plastics material and the chamber has a central axis arranged at an angle to the longitudinal axis of the slot, and a stop for the latching member is provided in the region of the opening of the chamber.
Claims (7)
1. Inner sealing sleeve for inserting into pipes, comprising a sleeve body made of an annularly bent band, wherein an inner band end and an outer band end overlap 5 and wherein the sleeve body can be expanded so that the inner band end can be displaced relative to the outer band end along an expanding direction and a locking arrangement is provided, which prevents the inner band end from being displaceable relative to the outer band end in the direction opposite to the expanding direction, wherein the locking arrangement has a slot arranged on the 10 inner band end in the circumferential direction and has a row of teeth, and a latching mechanism with a latching member, wherein the latching member is acted upon by a spring element and engages in the row of teeth, and the latching member and the spring element are arranged in a chamber of a guide body, wherein the latching member is displaceable in the chamber, wherein the spring element 15 consists of an elastic plastics material and the chamber has a central axis arranged at an angle to the longitudinal axis of the slot, and a stop for the latching member is provided in the region of the opening of the chamber.
2. Inner sealing sleeve according to claim 1, wherein the spring element is 20 incorporated between a side wall of the chamber and a rear wall portion of the latching member and the spring element presses the latching member towards an opening of the chamber, wherein latching teeth of the latching member project from the opening towards the row of teeth. 25
3. Inner sealing sleeve according to claim 1 or 2, wherein the chamber is covered by a cover.
4. Inner sealing sleeve according to claim 3, wherein the cover covers an upper flat side of the guide body.
5. Inner sealing sleeve according to claim 3 or 4, wherein the cover has longitudinally projecting guide tabs.
6. Inner sealing sleeve according to any one of claims 1 to 5, wherein the spring element consists of synthetic rubber.
7. Inner sealing sleeve according to any one of claims 1 to 6, wherein a recess is 5 provided at one end of the slot for the latching mechanism to pass through.
