Definitions

  • the invention relates to a cover of a manhole cover with a cover body and at least one locking means arranged on the cover body, which has a spring section and an engagement section arranged thereon and engageable with 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.
  • the locking means has a resilient arm, which is formed with its one end on the underside of the cover body on a stiffening rib and with its free other end extends essentially parallel to part of the circumference of the cover.
  • a latching lug is provided as the engaging section and sits at its free end transversely to the longitudinal extension of the resilient arm.
  • the resilient arm is resiliently movable transversely to its longitudinal extent, the locking lug being correspondingly biased in the direction of the frame by the resilient arm.
  • the present invention now proposes to fasten the spring section with its two ends to the cover body and to keep it apart from the cover body and to arrange the engagement section between the two ends of the spring arm.
  • the spring section functions in the manner of a leaf spring clamped at both ends. It has been found that the construction according to the invention can be used to implement a lock which functions particularly effectively and at the same time is particularly easy to handle.
  • the spring section preferably extends approximately parallel to the cover body.
  • a particularly preferred embodiment of the invention is characterized in that the spring section is designed as an annular body which is fastened to the cover body with a holding section which essentially unites the two ends of the spring section. Because in this embodiment the spring section is essentially closed with its two ends to form an annular body, it has the function of a double leaf spring arrangement with two leaf springs arranged in parallel, the one half of the annular body between the ends of which engage portion, the function of the first leaf spring and the second half of the annular body, between the ends of which the holding portion is located, the function of the second leaf spring. With such a construction, the efficiency of the spring action can be increased even further.
  • the ring body can have any shape, provided that the spring section is curved so that its two ends meet or are at least or arranged adjacent to one another.
  • the ring body can have, for example, approximately the shape of a circle, the engagement section expediently being arranged at a point substantially diametrically opposite the holding section.
  • the ring body can also have the shape of an oval, for example, with two, preferably semicircular, curved sections and two essentially elongated sections connecting these curved sections to one another. Because the shape of such an elongated oval is particularly suitable for increasing the spring effect.
  • the holding section should preferably be arranged on one elongated section and the engagement section on the other elongated section.
  • the elongated section carrying the engagement section can spring back relative to the ends of the curved sections which are connected by this elongated section, as a result of which the annular body can be adapted particularly well to the structural conditions, both in terms of the desired spring action and in terms of space requirements.
  • the engagement section expediently has a wedge-shaped catch section, as a result of which the engagement takes place as a catch.
  • the latching section is provided with at least one surface inclined in the engagement direction.
  • the locking means is usually arranged on the underside of the cover body.
  • the locking means should be arranged on the cover body at a distance from the stiffening ribs, which results in a particularly space-saving arrangement of the locking means.
  • Figure 1 is a perspective bottom view of a cover of a manhole cover
  • Figure 2 is a bottom perspective view of an arrangement of the lid of Figure 1 on a frame
  • FIG. 2a shows an enlarged detail view of FIG. 2
  • 3 shows a cross section through the arrangement of lid and frame shown in Figure 2
  • FIG. 3a shows an enlarged detail view of FIG. 3 in sections.
  • a disk-shaped cover 10 is shown in a perspective bottom view, which together with a matching ring-shaped frame, which will be described in more detail later, forms a manhole cover.
  • the cover 10 of which the underside is shown in FIG. 1, has a disk-shaped cover body 12, the circumference of which is delimited on its underside by a circumferential web 14 projecting downwards.
  • This circumferential web 14 serves as a support when using the cover 10 in a frame, as will be described later.
  • the lid body 12 is provided on its underside with radially extending stiffening ribs 16.
  • a locking means 20 is arranged, which is provided on its outer side opposite the circumferential web 14 with a radially outwardly directed locking lug 26.
  • FIGS. 2 and 3 also show the associated annular frame 30 on which the cover 10 rests and which together with the cover 10 forms the manhole cover.
  • the frame 30 in the exemplary embodiment shown has an inwardly projecting, circumferential support surface 32, which lies in a plane that is in the installed state of the frame 30 in FIG
  • cover 10 lies with its circumferential, downwardly projecting web 14 on this annular support surface 32 of the cover
  • each locking means 20 has in the illustrated
  • Cover body 12 extends. In the illustrated embodiment, the
  • Ring body formed by a closed strip-shaped element, which is substantially perpendicular to the disc-shaped
  • Cover body 12 extends. As can be seen in particular in FIG. 2a, the ring body consists of two approximately U-shaped bends
  • the two elongated sections 23 and 24 connect the curved sections 21 and 22 to each other, whereby the one thus formed
  • Ring body receives an approximately oval shape.
  • the annular connecting means 20 is formed on the underside of the lid body 12 via a holding section 25, while the remaining section of the annular locking means 20 is separated and spaced from the underside of the lid body 12.
  • the locking lug 26 is seated in a radially outward arrangement.
  • the locking lug 26 is arranged on the ring body of the locking means 20 at a point which is essentially radially opposite the holding section 25.
  • the locking means 20 has a mirror-symmetrical shape, the axis of symmetry (not shown) of which runs approximately radially.
  • the holding section 25 and the locking lug 26 are also located on the axis of symmetry.
  • FIG. 2a in particular reveals that the elongated section 23 carrying the locking lug 26 springs back a little compared to the ends of the curved sections 21, 22 which are connected by this elongated section 23. Therefore, in the illustrated embodiment, the shape of the locking means 20 can at least remind a little of the shape of a butterfly.
  • the section of the oval locking means 20 which is exposed relative to the cover body 12 and which is formed by the two curved sections 21, 22, the elongated section 23 and the outer edge sections of the elongated section 24, develops a spring action in the manner of an arrangement formed from two parallel leaf springs in the radial direction with respect to the stationary holding section 25. In this way, the detent 26 is resiliently biased in the radial direction.
  • the annular locking means 20 is integrally formed on the cover body 12 with the aid of the holding section 25, the locking means 20 is made of the same material as the cover body 12. This is usually a cast material with which the desired construction is possible due to the construction described above Spring effect of the locking means 20 can be easily achieved.
  • the cover 10 is locked on the frame 30 with the aid of the locking means 20 in that the catch 26 engages under a web 34 which is arranged on the inside of the frame 30 and projects inwards by one on the outside of the Latch 26 formed inclined surface 28 comes into contact with a correspondingly inclined counter surface formed on the underside of the web 34.
  • the locking lug 26 is subjected to a forced movement in the direction of the center of the cover 10 against the radial bias exerted by the oval locking means 20.
  • the oval locking means 20 buckles a little in the direction of the holding section 25 by shortening the distance between the two elongated sections 23 and 24 accordingly.
  • the same temporary change in shape of the oval locking means 20, which is favored by the construction described above, also occurs when the cover 10 is pulled out of the frame 30 and thereby the locking lug 26 is brought out of engagement by the counter surface 36 on the frame 30.
