Definitions
- the invention relates to a cover of a manhole cover with at least one locking means provided on the cover, which has at least one spring arm with an engagement section which can be brought into engagement with a part of a frame. Furthermore, the invention relates to a manhole cover with such a cover and a frame receiving it.
- Manhole covers with such a lock are known and are in diverse use.
- WO 86/04624 discloses a self-locking manhole cover in which the resilient arm is formed on a stiffening rib on the underside of the cover and extends essentially parallel to part of the circumference of the cover.
- the present invention now proposes to arrange the spring arm in such a way that its engagement section can be moved at an angle smaller than a right angle relative to the adjacent section of the circumference of the cover.
- the engagement section of the spring arm can be moved approximately parallel to the adjacent section of the circumference of the cover.
- the engagement section of the spring arm preferably extends at an angle to the adjacent section of the cover.
- the engagement section of the spring arm extends approximately at a right angle to the adjacent section of the cover.
- the engagement section of the spring arm can extend approximately radially and in particular the spring arm can be arranged essentially radially.
- the spring arm can preferably have an arcuate section.
- the arcuate section can be arranged between the engagement section and a further section of the spring arm and the two sections can be approximately aligned with one another.
- a currently particularly preferred embodiment is characterized in that the locking means has two spring arms spaced apart from one another and preferably at least in sections running parallel to one another, as a result of which the locking effect of the locking means can be increased.
- the locking means has two spring arms spaced apart from one another and preferably at least in sections running parallel to one another, as a result of which the locking effect of the locking means can be increased.
- this should be curved outwards in each case, as a result of which the distance between the two Spring arms and thus the design of the locking means can be kept low in this embodiment.
- the engaging section expediently has a wedge-shaped latching section, as a result of which the engagement takes place as a latching.
- the latching section is provided with at least one surface inclined in the engagement direction.
- the spring arm is preferably attached to the cover with an end located away from the engagement section.
- the locking means is usually arranged on the underside of the cover.
- the locking means should be arranged on the lid at a distance from the stiffening ribs, which results in a particularly space-saving arrangement of the locking means.
- this engagement means is arranged at a distance from the locking means and is designed such that the tool can be brought into engagement with a part of the frame at the same time as a lever torque upon engagement with this engagement means apply the lid and thereby detach the lid against the action of the spring force of the spring arm from the frame.
- This embodiment thus allows the cover to be levered out of the frame with the aid of the tool, without the tool acting on the locking means.
- the engagement means preferably has a recess through which the tool can be inserted.

- Figure 9 shows a cross section through the peripheral portion of the
- the manhole cover described below has an annular frame 1 and a matching disc-shaped cover 10.
- the frame 1 is shown in FIGS. 1 to 3 and the cover 10 with a lock in a first embodiment in FIGS. 4 to 6 and in a second embodiment in FIGS. 7 and 8.
- the frame 1 shown in FIGS. 1 and 2 has on its inside an inwardly projecting, circumferential web 2, the upper side 2a of which forms a support surface for the cover 10 and lies in a plane which is essentially in the installed state of the frame 1 extends horizontally.
- An inwardly projecting, circumferential flange-like projection 4 is attached to the web 2, which in the exemplary embodiment shown is interrupted by a recess 6 at two opposite points.
- each of these cutouts 6 is delimited on both sides of the flange-like projection 4 by upper and lower inclined surfaces 6a and 6b tapering towards one another to the outside.
- the lid 10 has on its underside a web 12 running around the circumference (see in particular FIGS. 4, 5 and 7), with which the lid 10, when used in the frame 1, on the upper side 2a of the running web 2 of the frame 1 serving as a support surface rests. Furthermore, the cover 10 is provided on its underside with radially extending stiffening ribs 14.
- Two blocks 16 are arranged at two radially opposite points at a distance from the ribs 14 on the underside of the cover 10 which are each formed two spring arms 18.
- the spring arms 18 are arranged to float on the respective block 16 and are directed radially outward in the direction of the circumference 10a of the cover 10.
- the spring arms 18 of each pair of spring arms 18 extend parallel to one another and to the cover 10 and at a distance from the underside thereof. Accordingly, the spring arms 18 are in the installed state of the manhole cover with the cover 10 inserted in the frame 1 approximately in a horizontal plane which runs parallel and at a distance from the plane spanned by the cover 10.
- Each arrangement of the block 16 and the pair of spring arms 18 attached to it forms a locking means for locking the cover 10 to the frame 1.
- the spring arms 18 can be moved with their free ends 18a towards one another and thus in the direction of the circumference 10a of the cover 10 against the action of an inherent restoring spring force and serve as latching elements for latching in the recess 6 of the frame 1.
- the spring arms 18 are straight and provided with a wedge-shaped outside, which is formed by an inclined upper inclined surface 18b and an inclined lower inclined surface 18c, the two inclined inclined surfaces 18b and 18c pointed towards each other outward to run, as shown in Figure 6.
- the lid 10 is placed on the frame 1 so that the free ends 18a of the spring arms 18 are aligned with the recesses 6.
- the free ends 18a of the spring arms 18 come first with their lower inclined surfaces 18c in contact with the upper inclined surfaces 6a of the recess 6 of the frame 1.
- the upper inclined surfaces 6a of the recess 6 cause the Spring arms 18 are pressed together at their free ends 18a until they pass the narrowing of the recess 6 formed by the two inclined surfaces 6a, 6b.
- the inside width of the narrowing of the recess 6 formed by the inclined surfaces 6a, 6b is one slightly larger than the sum of the width of the free ends 18a of the spring arms 18, viewed in the direction of the circumference 10a of the cover 10. Until the narrow point in the recess 6 is passed, the spring arms 18 are thus compressed against the action of the resilient spring force inherent in them. After passing the constriction in the recess 6 with continued movement of the cover 10 on the frame 1, the spring force inherent in the spring arms 18 causes the spring arms to be returned to the position shown in FIGS.
- the spring arms 18 with their free ends 18a on the cover 10 and the recesses 6 on the frame 1 form a locking or latching lock.
- FIGS. 7 and 8 show a second embodiment of the locking provided on the underside of the cover 10.
- the spring arms 18 'of this second embodiment are, like in the first embodiment shown in FIGS. 4 and 6, molded onto a block 16' on the underside of the cover 10 and in the same way on their outside with upper and lower inclined surfaces 18b 'and 18c' Mistake.
- the second embodiment differs from the first embodiment in that the spring arms 18 'have an outwardly bent portion 18d "between the free end 18a' and a portion 18e 'adjacent to the block 16', the bent portions 18d 'of the two Spring arms 18 'of each pair of spring arms 18' in the second exemplary embodiment shown are symmetrical to one another and the sections 18a 'and 18e' are aligned with one another.
- the bent sections 18d 'of the spring arms 18' serve to increase the resilient spring force the locking or latching locking effect reference is made to the description of the first embodiment given above with reference to FIGS.
- a pin-shaped tool 32 is inserted through a recess 30 provided on the circumference 10a of the lid 10 and brought into engagement with the underlying portion of the frame 1 in such a way that the tool generates a leverage effect allows the lid 10 to be lifted off the frame 1, as shown in FIG. 9.
- This leverage must be such that the restoring spring force of the spring arms 18 is overcome and, when the cover 10 is lifted from the frame 1, the free ends 18a of the spring arms 18 move along the lower inclined surfaces 6b of the recess 6 in the direction of their narrow point can. As a result, the spring arms 18 are compressed again until they pass the constriction of the recess 6 as the cover moves away from the frame 1.
