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.
- 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 spring arm is preferably attached to the cover with an end located away from the engagement section.
- FIG. 2 shows a cross section through the frame of Figure 1 along the dash-dotted line II-II shown in Figure 1;
- Figure 3 is an enlarged individual view of a
- Figure 5 shows a cross section through the lid of Figure 4 along the dash-dotted line V-V shown in Figure 4;
- FIG. 6 shows a sectional partial view of the cover from FIG. 4 along the dash-dotted line VI-VI shown in FIG. 4;
- Figure 7 is a view of the underside of a lid of the
- 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 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 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.
- 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.
