Description

Applicant: Blau K.G. Automobile Parts Factory < 4ol8 -Langenfeld / Rhld.

Bis drawing: bayonet latch, especially below

Spring pressure effect within the cap bayonet catches can be tightened by turning.

The subject of the application is training in particular for under the action of spring pressure within bayonet latches engaged by closure lids by turning movement with pretensioning compared to run-up curves of F '- ^ ltei "- or pipe socket parts to be closed

In addition to the usual fastening of a bridge part with a downward angled bayont. u- ^ iegelenden directly in the middle on the inner surface of a cap by riveting (DGl / t-1838672), are also arrangements of bayonet bolt bridges within locking lids with interposed, known at the bottom of a lower cover part supporting compression spring, whereby when turning the Cover the bayonet latch through cutouts from the lower part of the cover to the outside, under compression spring tension against the edge of the the nozzle part to be closed can be tightened. (DP-718875 or Iol3979).

The bayonate locking parts reaching through to the outside from the lower part of the cover can in this case be arched upwards or downwards for reinforcement, so that their lateral limits pa

In Fig.l and 2 a uniformly composed of upper cap 1 and lower Decirslteil 2 closure lid with through cutouts 3 to the outside reaching through bayonet latches 4 * of the internally embedded bridge 4 is shown, between bridge 4 and the pot-like retracted bottom of the lower lid part 2 is usually shown a compression spring is incorporated, whereby the bayonet ^{latch 4 1 can be} tightened under compression spring tension against the Auf1aufkanten a connection to be closed, which details are not part of the subject matter of the invention invisible here.

The decisive factor for the invention is the surface pressure of the side surfaces of the bayonet ^{latch 4 'to reduce the lateral delimiting edges 3 1} for penetration within fier cutouts 3 in the cover wall 2, since when using the previously common design form for bayonet latches 4' - as they are about are shown in Fig. 7 or 8/9 with lateral edge effect press like a chisel against the vertical delimiting edges 3 ^{1 of} the cutouts, and so can lead to damage to the cover housing.

In an embodiment according to Fig. "1/2 are to

^{For this purpose, the bayonet latches 4 1,} which are usually arched for the purpose of reinforcement and at the same time for easier running against the run-up edges in the connection piece to be closed, are provided with vertical cut surfaces 4 ″, in order to press parallel running in the penetration against the vertical cut-out edges 3 'on a relatively wide surface support, which has so far been the case disadvantageous edge effect of bayonet ^{locks compared to the lateral delimiting edges 3 1 of} the cutouts 3 in the event of a rotary movement of the closure cover 1/2 with outwardly penetrating bending parts 4- ¹ .

An expedient design form in this way for bayonet locks is also shown in FIG. With 14-'is here a bridge-like, strongly arched cross-sectional shape for bayonet latches, roughly in the manner of a half hollow cylindrical shape with then downwards then on both sides to the cutout edges 3' in ^ he cover wall 3 parallel support-like parts 14 ", so that again relatively wide surface support of these surface parts 14, which are perpendicular to one another on both sides, is given ^{in reaching through to the cut-out surface edges 3 1.}

In Figure 4, a weaker arched bayonet ^{locking part 4 - 1 is} shown, which has strongly rounded material surfaces on both sides, denoted by 4 rtl, when the cover is rotated, press against the side edges 3 ¹ in the penetration of the cutout 3 with low surface pressure.

Another expedient design form for bayon, pan according to the invention is shown in Fig. 5, where only the middle part at 4 ¹ upwards

is arched, connect horizontally on both sides -

the wing parts with outside vertical landing surfaces / parallel to the cut-out edges. 3 y

In Figure 6, the cross-sectional shape of the bayonet bar is in the known way for reinforcement in the shape of a circular arc and laterally radially inclined with protruding edges, now shown not to let the laterally protruding edges come into effect against the side edges of the cover cutout 3 in the previously disadvantageously described manner, According to the invention, these side edges 3 "are cut parallel to the inclined end surfaces on both sides of the bayonet latch 4 'so that a trapezoidal cutout 3 is formed, and in turn the full width of the side surfaces of the latch 4' is pressed against the inclined surfaces 3" lying parallel to this, so ^e protruding edge effect ljfcft the bayonet "rlegeJL-A ¹ to the side can jentstehen ·

When using such usually designed bayonet latches 4 'in the form of a circular arc and with protruding edges on both sides, their disadvantageous effect compared to the cutout edges H can also be avoided according to a further embodiment of the invention in Pig are formed by inwardly drawn material ^{parts 2 1} , so bead-like drawn-in side boundaries are created by inwardly pressed material flaps, and reinforcements 2 ¹ formed in this way are sufficiently resistant to any edge effects. For the same purpose, both sides of the cover cutout can also be reinforced in a bead-like manner according to the wide range of embodiments in FIGS.

In Pig.Io a crank of the bayonet bolt 4 'provided for reinforcement only on one side, namely Ti of the side lying in the locking direction of the lid, can be seen, while the bolt 4 ^{1 is} arranged horizontally with an end surface 4 "perpendicular to the other side. parallel to the cut edge 3 ¹ turn _$ around when opening the closure lid 1/2 relatively to each other wide rest area with correspondingly lower Plächenpr ^ the other cutout edge saung these two oppositely acting surfaces 3 ^x / create ^4-M. also in this case, if necessary, thought to be parallel to the cranked end face of the bayonet catch so that the protruding edge of the cranked locking part cannot come into effect, as it does

th 3 "of a section 3 was shown.

In order to achieve the largest possible lateral bearing surfaces of the bayonet latches without edge effects, finally, in a further expedient embodiment of the subject invention according to FIG. 11, it is also possible to proceed in such a way that the material ^{ends of the bayonet latches 4 1} are folded upwards or downwards, so that correspondingly reinforced and "wider lateral support surfaces 4 "" arise in relation to the side edges of cutouts 3 in order to be able to achieve lower mutual surface pressure.
