Definitions

• the present invention relates to a can-shaped container element, preferably a socket with a hinged lid element for opening and closing the can-shaped container element according to the preamble of claim 1.
• Can-shaped container elements which can be closed in this way are generally used wherever a quick and easy locking option is required in order to prevent contamination of the material stored in the can-shaped container element or of the internals located there.
• a typical area of application is socket outlets which can be closed by means of a hinged cover element, both for industrial and for domestic use. To prevent the socket from becoming dirty, these sockets can be closed by means of a hinged cover element.
• the hinged cover element is preloaded by means of a torsion spring mounted in a spring box, which presses the hinged cover in the direction of the opening of the socket, so that accidental opening of the hinged cover Lelement is not possible. If the user releases the hinged lid element from the open position, it is automatically pressed against the corresponding end face of the socket.
• the storage of the hinged lid element on the container element takes place asymmetrically and / or is made very filigree in many such known combinations. This means that the connection between the hinged cover element and the container element is often destroyed and can therefore no longer be used.
• Hinged lid element on the container element whereby the forces that occur are always introduced symmetrically into the two elements.
• the characteristic feature of claim 2 prevents accidental loosening of the hinged lid element-container element connection. Due to the stub axles arranged on both sides of the web, the hinged lid element cannot be detached from its attachment to the container element by lateral loads, as is often the case, for example, with a power cable wrapped around the hinged lid.
• the torsion spring can be snapped into the socket in order to build up the necessary tension to close the hinged cover element.
• Fig.l is a bottom view of a hinged lid according to the invention
• FIG. 2 shows a sectional view along the line AA from FIG
• FIG. 3 shows an axonometric bottom view of a hinged lid element according to the invention
• FIG. 5 shows an axonometric view of an end face of a container element of a socket
• FIG. 7 shows a can-shaped container element including the hinged lid element in the assembled state
• a hinged cover element 1 according to the invention with seal holder 2 and actuating aid 3 is shown.
• a spring box 4 which includes a spring chamber 5, is provided.
• the spring box 4 has an opening 6 which leads directly into the spring chamber 5, which is formed by an essentially cylindrical guide part 7 and whose end walls have cylindrical openings 8, 9, which can also have different diameters.
• the spring case 4 furthermore has slots 11, 12 opposite one another on each of its two longitudinal sides.
• a further slot 10 is formed by a tongue-shaped web 31 which projects into the opening 6 and which extends up to a distance from the opposite side of the opening 6.
• the tongue-shaped web 31 is made in one piece with the spring box 4 and at the same time forms part of the boundary of the opening 6.
• two tab-shaped struts 14, 15 are provided along their edges with chamfers 33, which are separated from the spring box 4 by two slot-shaped recesses 16, 17.
• the two tab-like struts 14, 15 have two cylindrical openings 18, 19, which are aligned concentrically with the cylindrical openings 8, 9 of the spring box 4.
• FIG. 5 shows a can-shaped container element designed as a socket 20, one end of which can be closed with a hinged lid element 1.
• On the end face are two webs 21, 22, each having cylindrical stub axles 23, 24 on both sides.
• the diameters of the stub axles 23, 24 are matched to the diameters of the cylindrical openings 8, 9 of the spring box 4 or to the openings 18, 19 of the tab-like struts 14, 15.
• Both the edges of the struts 14, 15 and the stub axles 23, 24 are provided with chamfers 32 which serve as run-on bevels and the insertion of the stub axles 23, 24 into the slot-shaped recesses 16, 17 and subsequently into the openings 8, 9 or 18.19 facilitate.
• the chamfers 32 on the stub axles 23, 24 are oriented such that they are directed away from the element 20, 1, depending on whether they are arranged on the can-shaped container element 20 or on the hinged lid element 1. This has the advantage that when the hinged cover element (1) is open, a tensile force on the stub axles 23, 24 only act in that region of the circumference which has no chamfer. The accidental loosening of the connection can thus be prevented.
• the chamfer 32 thus only serves to assemble the hinged lid element (1) and the container element (20), but not to loosen the connection.
• There is a run-on slope 25 with a latching edge 26 between the webs 21, 22. 6 shows a torsion spring 27 together with spring legs 28 and 29, the latter having a bent end region 30 in the relaxed state.
• Fig. 7 an outlet including the hinged lid are shown in the assembled state.
• the torsion spring 27 is in the tensioned state.
• the spring leg 29 is located in the slot 12. If the hinged cover part 1 is closed, the spring box 4 rotates so that the spring leg 29 is in the closed state of the hinged lid part in the slot 11.
• the torsion spring 27 is fed in the position aligned parallel to the imaginary axis of rotation of the hinged cover element 1 with the spring leg 28 matching the slot 10 through the opening 6 into the spring chamber 5 of the spring box 4. A slight compression of the torsion spring 27 is required. Furthermore, the two rotating legs 28, 29 of the torsion spring 27 run on the inner walls of the opening 6 of the spring box 4, as a result of which their angle with respect to the relaxed state (FIG. 6) changes and the torsion spring 27 is thereby preloaded.
• the torsion spring 27 By means of lateral pressure on the torsion spring 27 in the direction of the imaginary axis of rotation of the hinged cover element 1, the latter is pushed under the tongue-shaped web 31 up to a stop surface 13 of the spring chamber 5, which is formed by the smaller diameter of the cylindrical opening 9.
• the opening 9 is of the same size as the openings 8, 18, 19, the lateral movement of the torsion spring 27 being limited by the snap-in of the spring legs 28, 29 in the slots 10, 11.
• the spring leg 28 is simultaneously pushed into the slot 10.
• the web 31 prevents the torsion spring from under load Spring chamber 5 pops out. This object is normally achieved by an axis of rotation made of metal or plastic, which, however, can be omitted due to the web 31 according to the invention.
• the hinged cover element 1 is then pushed onto the socket part 20 with the torsion spring 27 fixed, the spring leg 29 of the torsion spring 27 engaging with the bent end 30 behind the latching edge 26 of the socket part 20. Furthermore, the two webs 21, 22 dip into the slot-shaped recesses 16, 17 of the hinged cover 1 between the tab-shaped struts 14, 15 and the spring box 4, whereby the tab-shaped struts 14, 15 and the webs 21, 22 spring open and the cylindrical stub axles 23 , 24 snap into the cylindrical openings 8, 9 of the spring box and into the cylindrical openings 18, 19 of the tab-like struts 14, 15. In order to facilitate the engagement, the cylindrical stub axles 23, 24 or the edges of the struts 14, 15 are provided with chamfers 32, 33 as described above. The spring leg 29 migrates during the opening of the
• Hinged lid element 1 from a position in slot 11 in the closed state of hinged lid element 1 to a position in slot 12 in opened state of hinged lid element 1.
• the spring box 4 according to the invention is arranged on the hinged cover element 1 and the webs 21, 22 together with the stub axles 23, 24 on the socket element 20. A rearrangement of the spring box 4 to the socket element 20 and the webs
