Definitions
- the present invention relates to a device for holding captive at least one hinge axis in a conjugate housing of a cap element, such as a grid or a buffer, intended to be mounted articulated on a support frame by the intermediate of this axis.
- a cap element such as a grid or a buffer
- the installation mountable articulated mount of the cap element to its support frame consisted of housing, just before the installation of the crown member on the frame, at least one axis of articulation in a housing made in one side of the crown element near its hinge edge to the frame and parallel to the latter.
- the present invention aims to eliminate the above disadvantage by providing a device for making captive the hinge axis in its housing of the cap element.
- the device for keeping captive at least one axis of articulation in a conjugate housing of a cap element, such as a grid or a buffer, intended to be mounted articulated on a frame of support via this axis is characterized in that it comprises a pin removably fixed in a piercing of the cap member transversely to the housing of the hinge pin so as to axially retain this axis in the housing against the biasing force of an elastic member mounted prestressed in the housing between the bottom thereof and the end of the axis opposite to that bearing on the transverse retaining pin.
- the elastic return member is a helical compression spring mounted in the housing coaxially with the hinge pin.
- the axis of articulation has a length such that after removal of the pin, the axis partially projects from the cap member under the action of the restoring force of the elastic member.
- the hinge axis is advantageously cylindrical.
- the crown element may have a rectangular shape and the housing of the hinge pin is then made in one side of the crown element parallel to the corresponding hinge edge of the crown element and close to this shore.
- the housing of the hinge pin and the piercing of the cap element come from foundry.
- the invention also relates to a crown element, such as a grid or a buffer, in particular for manhole, and which is characterized in that it comprises a device as previously defined.
- the invention further relates to a method of installing a cap member, such as a grid or a buffer, hingedly mounted on a support frame, the cap member being provided with a device as defined above, and which is characterized in that it consists in placing the crown member on the frame with the hinge pin held captive in its housing of the crown member and removing the pin from the cap member so as to allow the resilient member to push the axis partially out of the housing and introduce it coaxially into a blind hole forming a keeper of the frame.
- Figure 1 is a perspective view of a hinged crown member on a support frame
- Figure 2 is an enlarged sectional view along the line II-II of Figure 1 and showing the device of the invention for enclosing a hinge axis in the cap element
- Figure 3 is a sectional view similar to that of Figure 2 and showing the hinge axis released at its hinge position of the crown member to the frame.
- the reference numeral 1 denotes a frame which has a rectangular shape and on which is articulated a cap element 2 constituted in this case by a grid, it being understood that the cap element 2 may be constituted by a tampon or lid.
- the frame 1 is embedded in the pavement so that the cap element 2 makes it possible to close a manhole.
- the coronation element 2 has its bank 3 mounted articulated to the corresponding bank 4 of the following frame 1 a hinge axis X1, X2 extending parallel to the banks 3, 4.
- the articulation of the crown element 2 to the frame 1 is of the type that does not allow the dismantling or extraction of the element 2 from its frame.
- the cap member 2 is housed, in its closed position of the frame 1, in a rabbet 5 of the frame 1 and can rest on a peripheral seal 6 housed in the rabbet to reduce the mounting noise of the element 2 in its frame.
- the cap element 2 before articulated mounting of the cap element 2 in its frame 1, the cap element 2 is provided with at least one cylindrical axis of articulation 7 captively imprisoned in a conjugate housing 8 made in the coronation element 2 and opening on one side of the latter.
- the housing 8 is formed in the hinge side 3 of the element 2 from the side of this element extending parallel to this side and coaxially with the axis of articulation X1, X2.
- the hinge pin 7 is held captive in its housing 8 by a pin 9 removably fixed in a bore 10 of the cap member 2 and made perpendicular to the longitudinal axis of the housing 8, the pin 9 thus passing through this housing .
- the pin 9 exerts on one end of the axis 7 an axial force such that the opposite end of the axis 7 compresses a helical compression spring 11 between this end and the bottom 8a of the housing 8.
- the pin 9 is partly projecting from the upper face of the hinge flange of the cap member 2 so that it can be grasped and removed manually from this element.
- the housing 8 and the piercing 10 of the cap member 2 come from casting.
- the pin 9 now captively the hinge pin 7 in the housing 8 of the cap member 2, the latter can be stored and / or manipulated without risk of loss of the hinge pin 7.
- the assembly of the articulation of the cap element 2 to the frame 1 is already apparent from the foregoing description and will now be explained .
- an operator grasps the crown member 2 to place it on the frame 1 by introducing the axis of articulation of the element 2, opposite to the captive articulation axis 7, in the corresponding striker of the frame 1 or the end of the articulation flange 3, then places the element 2 fully supported in the rabbet 5 of the frame 1 as shown in Figure 1.
- the striker 12 may be constituted by a blind hole.
- the device of the invention is of a very simple and inexpensive design since it uses commercial components.
