Abstract

The strip (100) for mounting to door and window frames (1) and strip section (20) for mounting to the window or door pane frame (2) is bonded wholly by pressing the pin (30) along its length into an opening (21). The pin has projecting locking sections (33) round its circumference, which are pressed by an elastic force into the pin body when it is pressed into the opening of the mounting section (4). When the pin is pressed fully home, the projection reasserts itself against a shoulder (24) within the opening away from the pin body. For removal, the projection is moved by a tool away from the shoulder towards the pin body. The pin is an injection moulded plastics component.

Description

The invention relates to a volume of the preamble of claim 1 corresponding Art.

The tape parts of such tapes are by means of at the front through the belt parts into the fixed ones Frame or the bracket of screwed fastening screws attached to the frame or sash.

The terms "front", "front", "back" are thereby from one of the opening side of the wing the hinge mounted on the fixed frame or sash understanding viewer.

Since tapes of the generic type on a larger scale be used, especially since the advent the frame profiles made of plastic and aluminum alloys the case is it is known the area of the heads the fastening screws by means of a not removable from the front, to be attached to the relevant band part Cover the cover piece. While this also has aesthetic Reasons in so far as the striking countersinking of the person concerned Belt part and the screw heads no longer from the front are visible, but the real reason for that Cover pieces the security aspect. Without the cover pieces could namely the wing by unscrewing the fastening screws can be easily opened by unauthorized persons. Therefore, the cover pieces must be non-removable from the front, if they should fulfill their safety function.

In older embodiments (DE-GM 73 17 785) for example, the cover pieces have been pinned, but what had the disadvantage that after tightening the Fastening screws and the attachment can no longer be removed were. However, there is a need in some cases then remove a tape after assembly. On Example of a tape where this is possible runs out the unpublished DE-GM 296 16 715.0 or the corresponding EP 833 030 A1. The one at the back of the cover piece attached contains one Cross bolt through the access of the fastener can be operated and with the pin pressed in behind the heel can be brought to attack, so that the pin with the cover cannot be pulled out again. To the temporarily holding the pin in the assembly on the pin a tongue with a radially outward directed projection provided, which extends to a paragraph of the recess. The tongue is not used for Establishing the secure connection between the Cover piece and the band part. This also requires Assembly of the cover piece an actuation process by the back of the tape part is to be performed, namely tightening the cross screw. Something tricky like that Assembly processes are the standard equipment of Frame and wings with ribbons an obstacle.

This obstacle is with the tapes of DE-GM 93 15 327 that discloses all the features of the preamble of claim 1, and the DE-GM 94 13 892 avoided. The one in these two Writings shown covers can be seen from the front just press on and snap in one Locked position without any operations from the back of the tapes are necessary. However, this cannot be done with simple plate-shaped Cover pieces are worked, but it must be both on the cover pieces as well as on the band part in question projections engaging each other and Undercuts can be provided by snapping of the substantially cylindrical pin in a cylindrical bore are held in engagement. This means that the cover pieces press sideways while back the pin must be pushed to the projections and To bring undercuts into engagement. This requires an attentiveness during assembly and sets in remaining precision in the execution of all involved Moldings ahead, which only take a certain amount of effort ensure is.

The invention has for its object a generic To develop the band in such a way that it was at No assembly to be carried out from the back of the belt Operations require that it be purely from the front can be assembled without difficult lateral pushing operations and that it is again without destruction when the wing is open is solvable.

This object is represented by the one in claim 1 Invention solved.

The cover piece is with the pin in its longitudinal direction simply pressed in without being on the side Position must be respected. Upon reaching the The connection is made when the cover piece abuts the belt part automatically, with the sash open again can be canceled.

The locking element can when pressing in Pin in its axial direction in the recess of the band part solely by this shift in the cross-sectional outline of the pin are pushed back without it of a process other than that of the mere Pressing in the axial direction of the pin is required. When reached the locking element jumps to the end position of the cover piece under the action of the elastic force radial in front and sits behind the paragraph to make the connection between cover piece and band part. However, with the sash open, it is suitable Tool possible, the locking element back in Pushing back the cross-sectional outline against the elastic force, so that the pin pulled out again and that Cover piece can be removed.

The locking element can in a first embodiment be formed according to claim 2.

The tongue on the cones has a non-energetic rest position, in which the protrusion over the cross-sectional outline of the pin protrudes. When the pin is pushed in, the tongue becomes under Bend in a plane passing through the axis of the pin pushed back and jumps after reaching the paragraph under the back of it again.

If the projection on the tongue according to claim 3 the side facing the paragraph is designed obliquely, so results from the elastic force of the tongue and the Oblique a force acting in the axial direction of the pin, which pull this into the recess of the band part strives. This configuration leads to a certain Prestressing the system of the cover piece on the belt part and thus permanent freedom from rattling.

In particular, the pin with the tongue according to Claim 4 be formed, which makes it possible to have the spring constant the tongue when pressed into the cross-sectional outline to increase.

Instead of a single tongue on an otherwise the preferred embodiment cylindrical and in a matching recess formed as a bore of the band part To provide pins, it is also possible according to claim 5 to provide two opposing tongues, be it on a pin still present next to it, be it that the whole pin consists of the two tongues.

In the latter case, it can be recommended that the Tongues, starting from the roots, bent back inwards are and with the bent back ends together concern (claim 6) so that they are supported against each other can and the achievable radial force of the tongues gets bigger.

The embodiment according to claim 7 is particularly for the production is suitable as a bent sheet metal part.

While the tongues in those described above Embodiments at the end close to the cover piece with the Pins were connected, claim 8 describes an alternative Embodiment in which the tongues at the free end of the pin are connected to this.

A technically simple possibility of Realization of such an embodiment is the subject of claim 9.

All that is required is a simple molded plastic part and a simple bent part made of steel.

Another embodiment, the special advantages if the pin is made entirely of plastic, is described in claim 10.

An important further embodiment is the subject of claim 11.

A separate locking member is provided here which is displaceable in the transverse recess of the pin and under the action of a spring force radially outwards is pushable.

In particular, this can be done in the claims to 14 reproduced manner can be realized.

Another possible embodiment with transversely extendable locking member uses the so-called "ballpoint pen principle" and is in claim 16 described. The refill of a ballpoint pen has a stable one Intermediate position in the writing position. Will she pushed out further, so it pulls when the Pressure passing the intermediate position all the way into that Ballpoint pen housing back. When pushing out again the pen refill beyond the intermediate position however, the pen refill does not go back into it Ballpoint pen housing back, but remains in the stable intermediate position.

This principle is according to claim 15 on the lock the pin of the cover has been transferred. The Locking member has a stable intermediate position, in which it is radial a little over the cross-sectional outline of the Protrudes. When pushing the pin into the The locking member becomes recess of the fastening part completely pushed back into the cross-sectional outline. there it is under an elastic force that radially follows it is trying to push outside. Once the paragraph of the recess is reached, the locking member jumps radially before, beyond the intermediate position up to the the end position corresponding to the function as a lock.

To achieve the "ballpoint pen function", the design provided in claim 16, but with the formation of the projections on the boundary the transverse recess and the formation of the interacting with it Ends of the locking arms taken as known are to be seen.

The spring that the locking member radial expressive force can in the in claim 17 described manner.

Material and manufacturing method of the parts of the fastening of the cover piece depend on the individual case the intended design and for this taking into account the Economic aspects available technical possibilities.

Such a possibility is according to claim 18 Manufacture of parts as molded plastic parts.

Sometimes an application limit is set by the Strength can be achieved. For this reason, often the alternative can be considered, the parts as pure Form sheet metal parts (claim 19), in many Cases of compromise, that is, the mixed mode of execution, which will be given.

In the production of the pin from sheet metal, this can formed as a cup-shaped pressed sheet metal part be in which the tongues from the wall of the pot punched out (claim 21) and in the region of the bottom of the Pot can be connected to this (claim 22).

According to claim 23, the paragraph in the material of the Band part may be formed, for example by one of the back of the band part ago coaxial to the recess larger diameter blind hole for the pin.

But it can also according to claim 24 of the paragraph a separate, in an additional recess of the fastening part of the band part used formed part be, which in turn is the paragraph, that is the recessed edge or the undercut, forms.

In particular, such a shaped piece can be used as a stepped disk be formed according to claim 25, wherein the Orientation of the level forms a security feature insofar as this gives access to the pin of the cover piece from the outer, that is, the bottom or top Side of the tape can be locked here. The design according to claim 26 it allows with the spigot far to reach the area of the stepped washer below.

The attachment of two such indentations Claim 27 allows the use of the step plate for right and left.

Usually the stepped washer is tight in the additional recess pressed in so that it is not lost can go. To put them in the correct position Bringing to the right or left stop can be a design for attacking a turning tool according to claim 28 be beneficial.

The cover can be seen in claim 29 Formed and connected to the pin, which in itself, however, e.g. from DE-GM 72 12 721 is known.

The cover piece is on the pin in the recess and the groove led and finds its final location from itself, in which it is parallel to the plate plane in all directions and is perpendicular to it. The attachment of the Cover piece can be done in this way with one hand respectively.

In Fig. 1 are a fixed frame 1 and Sash frame 2 made of aluminum hollow profiles recognizable, which pivotable about a hinge axis A by a band 100 are interconnected. The band 100 comprises a frame band part 10 and a wing band part 20, which are in view with regard to their basic structure, especially with regard to the same for the attachment of the cover pieces 12 are and of which therefore only the frame hinge part 10 in is described in detail below.

The frame hinge part 10 comprises one at the front vertical flat mounting surface 3 of the fixed Frame 1 adjacent fastening part 4, the corresponding has a rear flat contact surface 5. With the fastener 4 is integrally connected to a hinge part 6 with a cylindrical recess 9, in which the in 3 not shown and in FIGS. 1 and 2 with 7th designated hinge pin arranged in a hinge pin bushing and forms the hinge axis A. The hinge part 6 stands with its rear side from the mounting surface 3 by a distance of 8. The hinge part 6 is therefore opposite the contact surface 5 of the fastening part 4 both forward according to route 8 as well as laterally corresponding to the distance 8 'between that through the axes the fastening screws 15 formed the center of the contact surface 5 and the hinge axis A given distance 8 ' laterally offset.

The band parts 10, 20 are fastened by means of Fastening screws 15, which have a head with an internal polygon have and from the front through the fastening part 4 and corresponding holes in the mounting surface 3 forming front wall of the frame profile in an Inside the fixed frame 1 arranged threaded piece 16 are screwed in. Generally are per band part 10, 20 two fastening screws arranged one above the other 15 provided. For exact fixing of the frame hinge part 10 on the fixed frame 1 parallel to Fastening surface 3 serve centering bushes 36 which Fastening screws 15 surround and both in the frame 1 and also engage in the fastening part 4.

In the oblique from the fastening part 4 to the Hinge part "rising" front of the frame hinge part 10 is continuous over the height of the same flat rectangular groove 14 formed, in which a rectangular Plate-shaped cover 12 is arranged, which extends over the height of the frame hinge part 10 and on the back one across the groove 14 extending across the width of the cover piece 12 T-groove 17 has. In the T-slot 17 is the side protruding head 18 one designated as a whole by 30 Pin led out of the cover 12 to the rear protrudes and its attachment to the attachment part 4th serves.

The cover 12 covers in the in FIGS. 1 to 3 shown assembled state the area of the heads the screws 15 and for them in the mounting piece 4 attached counterbores without the cover 12 the fastening part 4 to the front a very jagged Would give structure. But it is also through the Cover piece blocked access to screw heads, so that the frame hinge part 10 is not or only with destruction could be detached from the fixed frame 1.

The frame hinge part consisting of parts 4 and 6 10 and accordingly also the wing hinge part 20 and the Cover pieces 12 are extruded from an aluminum material, where the extrusion direction for the strip parts 10, 20 runs perpendicular to the plane of the drawing according to FIG. 1, so that these parts in the vertical direction (in the assembled Condition) a constant given by the manufacturing Have cross-section. The groove 14 is also mitangepreßt. The cover 12 is also an extrusion, however, its extrusion direction is parallel to the drawing level.

The pin 30 is approximately perpendicular to the cover 12 and engages in a hole formed Recess, 21 of the fastening part 4, which is perpendicular to the bottom of the groove 14 preferably approximately in its Middle runs. From the back of the frame hinge part 10, that is from the contact surface 5 is one to the axis 22 of the recess 21 coaxial blind hole of larger diameter introduced that up to about the middle of the thickness of the Fastening part 4 runs and there a paragraph 24 forms. From the blind hole 23 goes to the hinge part 6 out an expansion channel 25 that is just as wide, that a tool W (Fig. 2) fits into it. Paragraph 24 is important for the determination of the cover piece 12.

This determination is made with the help of the pin 30, that in the embodiment of FIGS. 1 to 4 as a plastic molding is formed, which on the hinge pin 7 remote side one with the head 18 piece semi-cylindrical shell-shaped shaft part 31 and the opposite side one with the head 18 on one End connected tongue 32 which at its lower End a radially outward projection 33 forms. The tongue 32 extends in the axial direction of the pin 30 along the wall of the recess 21. It is only in close to the head 18 connected to the pin 30 and can at its free end, where the projection 33 sits, in the direction of the arrow (Fig. 2) under elastic bending be pushed inwards. When you let go, it snaps however outwards again, the projection 33 behind paragraph 24. To the bending stiffness of the Tongue 32 can be elongated at the two Ends of steel spring insert bent in the opposite direction 34 can be provided (Fig. 2), which is at the top End in the head 18, at the lower end in the projection 33 extends. As can be seen from Fig. 3, the projection 33 on the when the pin 30 is pressed into the recess 21 leading side at a relatively flat angle beveled to the axis of the pin 30 so that the projection 33 when pressed into the recess 21 by the wedge effect the bevel 36 at the edge of the recess 21 is pushed away inside and the recess 21 in the axial direction can happen. The top 35 of the recess 33 is also beveled, but at an angle of almost 90 ° to the axis. This means that it is due to the friction it is not possible to pull the cover piece 12 forward, once the protrusion 33 is behind the paragraph 24 has arrived. With a suitable dimensioning of the Distance of the projection 33 from the head 18 but also that due to the elastic movement of the projection 33 an axial pull on the edge of the heel the pin 30 is created, the cover 12 always free of play and rattle in contact with the bottom of the groove 14.

There may be cases where the tape is 100 or e.g. the frame hinge part 10 must be replaced. at closed wing 2, the projection 33 is practical from the front inaccessible (Fig. 1). With wing 2 open, however exists through the blind hole 23 and the expansion channel 25 an access Z to the end of the pin 30 (Fig. 3). A tool W, e.g. one Screwdriver, from the area of the shadow groove, which is no longer blocked by wing 2, through the extension channel 25 through the slope 36 of the Projection 33 reached (Fig. 2) and this in the sense of Arrow are pushed back so far that the projection 33rd released from paragraph 24, the locking in the axial direction the pin 30 lifted and the cover 12 with the pin 30 can be pulled forward from the fastening part 4 is.

During the pin 30 in the embodiment of FIG 1 to 4 consists of a molded plastic part, is 5 from a one-piece bent sheet metal part formed, which is the shape shown in the drawing having. The head 18 consists essentially of one rectangular sheet metal plate, the width of which in the area of the transverse to the direction of the groove 17 located ends of the width of the T-groove 17 corresponds and is therefore guided in this. to Jump in the middle from the ones angled in accordance with FIG. 5 Edges of the head 18 two opposite each other strip-shaped tongues in front of the lower end corresponding to the contour of the projection 33 in FIG. 1 to 4 are shaped. Starting from the lead, the Tongues 38 inwardly bent legs 37 on the rest against each other with their free upper ends. Thereby the elastic force with which the Projection 33 is pressed behind the paragraph 24, which in this case by a spacer 8 in the fastening piece 4 drilled holes with an axis 26 is formed, which with the axis 22 of the recess 21st takes an angle of about 45 °.

In the embodiment of FIGS. 6, 7 and 8 the pin 30 again from a molded plastic part, which has a cylindrical shaft 39 and one rectangular, plate-shaped fitting into the T-groove 17 Head 18 includes. The shaft 39 has on the in Fig. 6 right side an outwardly open groove 40 and on the opposite side an inner recess 41, the in the longitudinal direction of the shaft 39 as well as the groove 40 extends almost to the lower end of the same. The outer wall 42 of the groove 41 is only thin. The groove 41 has an approximately quarter-arc-shaped cross-section, as is evident from Fig. 8 reveals. In the middle of the height of the shaft 39 is a projection 43 on the outside of the wall 42 provided that when inserted into the recess 21 Pin 30 for bearing on the wall of the recess 21 is determined.

To the pin 30 is a double hook 44 from one Spring steel strip with one free end engages in the recess 41 for a short distance from above, extends across the central part of the pin 30 and then from above through the groove 40 to its lower end extends where the end 45 of the double hook 44 there 135 ° is bent back, so that it is up again against has the head 18. It stands radially above the cross-sectional outline of the pin 30 over. 5 assembled in accordance with State, the double hook 44 engages with its end 45 behind the projection 24. When pushing back with of a tool W corresponding to FIG. 2, the pin 30 by attacking the tool W at the end 45 pressed to the left, the projection 43 the wall 42 dented and thus sufficiently elastic bridgeable There is scope to the free end 45 through the Let recess 21 step outwards.

9 and 10 is as a pure sheet metal bent part trained example of a pin 30 reproduced. The pin 30 consists of two fork-like legs 46, 47 approximately constant width, the upper part are doubled at 48 and there a larger one, the width have the corresponding width of the T-groove 17. The one Fork leg 47 has a right angle at the lower end outward projection 49 to reach behind of paragraph 24 is determined.

11 to 13 is the Pin 30 again as a pure sheet metal part 50 in a pot shape educated. The top edge is on two opposite one another Sides perpendicular to the top axis at 51 bent outside and bent back at 52 on the outer edge, so that two wing-like lugs 53 arise, the width larger than the diameter of the cup-shaped part 50 and corresponds to the width of the T-groove 17. The pin 30 can thus be free of play from the wings 53 in the T-groove 17 be performed. The wing-like lugs 53 form together the head 18. Near the bottom 50 'of the cup-shaped Sheet metal part 50 is a rectangular itself field extending a third of the height of the pin 30 punched out, which is only near the floor with the sheet metal part 50 is connected and, starting from the floor 50 ', is slightly inclined outwards so that it the locking element coming into contact behind the paragraph 54 can form, which if necessary with the help of Tool W elastic in the wall of the cup-shaped Sheet metal part 50 is bent back.

The embodiment of FIGS. 14 and 15 is correct in With regard to the pot-shaped sheet metal part 50 with the Embodiment according to FIGS. 11 to 13. The head 18, however, is obliquely funnel-like by a circumferential upward and outward flanging 55 of the upper Edge of the pot-shaped sheet metal part 50 formed in the T-groove 17 can be inserted.

In the embodiment of FIGS. 16 to 18, it can are again a sheet metal part. The pin 30 includes a high cylindrical shaft 56, in the Wall on top of each other in the lower area near the floor tongues 57 angled diametrically opposite sides are recessed, which are only at the lower end with the wall of the high cylindrical shaft 56 are connected and from there diagonally outwards to a vertex 58 extend from which the free end 59 of the tongue again runs inwards. The lower end and the free end 59 together form a projection, the outer contour of which that of the projection 33 of FIGS. 1 to 4 corresponds. The free end 59 lies behind when pin 30 is pressed in paragraph 24. At the upper end of the hollow cylindrical molding 56 are rectangular and perpendicular to the axis Plate parts 60 are provided which engage in the T-groove 17. This can be done to increase the elastic compliance Molded part 56 have longitudinal slots 61.

In the embodiment according to FIGS. 19 to 21 there is the pin 30 from a solid cylindrical fitting, which is made of plastic or metal, e.g. aluminum or zinc die casting can be made. At the top are opposite transverse grooves 63 are provided in the engage the free edges of the T-groove 17 so that the part of the fitting 62 lying above forms the head 18. At the bottom is on one side that the paragraph 24 facing, a transverse groove rectangular in cross section 64 formed in which one in a through the axis of Fitting 62 going plane C-shaped spring clip 65 is arranged, the lower leg obliquely after protrudes outside of the cross-sectional outline of the fitting 62 and the locking element reaching behind the paragraph 24 forms. The spring clip 65 is so elastic that by means of the tool W (Fig. 2) if necessary can be pushed back under the cross-sectional outline of the shaped piece 62 is.

22 to 24 is an embodiment of a Tang 30 reproduced as a pure sheet metal part is formed, but in which the locking member is not displaceable itself under elastic deformation but is a separate part, which is opposite the pin 30 transversely displaceable and by a separate Spring is elastically stored. The pin 30 includes a cup-shaped, essentially cylindrical shaft 67, all around at the upper edge to produce the head 18 expanded and flanged back and with the expanded Flanged edge engages in the T-groove 17. In the area below the shaft 67 is on opposite sides Digits 68 indented. In this area there is only one with its upper edge with the wall of the switch 67 in Linking tabs 69 through 90 °, so that a transverse channel 80 which is approximately square in cross section is formed (Fig. 22), in which a substantially cylindrical locking member 80 transverse to the pin 30 is movable. The locking member 80 has one cylindrical part 77 of larger diameter on the a cross-sectional transition 78 into a cylindrical part 79 of a smaller diameter, which is shown in FIG. 23 evident from the through the Tab 69 formed opening of the wall of the shaft 67th protrudes radially outward.

On the same axis is on the opposite A grommet 81 is put through from the outside, on which a helical compression spring 82 is arranged, which in the open cylindrical part 77 of larger diameter fits in and is supported on the cross-sectional transition 78. The helical compression spring 82 thus presses the locking member 80 to the right according to FIG. 23. So that Locking member 80 does not fall out of the pin 30 is the opening for the flap 69 through something punched out above the bottom of the pin 30 so that an edge 83 is formed on which the cross-sectional transition 78 comes to rest with its outside.

The locking member 80 can when inserting the Pin 30 in the recess 21 with the finger or Tool be pushed back until the introduction of the Pin 30 in the recess 21 is possible. When reached of paragraph 24, the locking member 80 jumps from even radially in front and can be used with the tool if necessary W can also be pushed back.

In the previous examples of FIGS. 1 to 3 on the one hand and Fig. 5 on the other hand, paragraph 24 was in Material of the fastening part 4 is formed. In the Fig. 25 to 28, an embodiment is shown at which the paragraph 24 in the form of a separate part a step plate 70 is formed, which is a circular has partially corrugated outer circumference and thus in one perpendicular to the contact surface 5 of the fastening part 4 of the recess 21 adjacent to the fastening part 4 or the hinge part 6 introduced additional cylindrical recess 71 is arranged. The step disc 70 has two parallel to its axis, through one just level 74 separate levels, namely one (in relation to the installation position) front level 72, the outer margin forms paragraph 24 and a rear plane 73, which is in the installation position according to FIG. 26 with the rear 6 'of the hinge part 6 of the frame hinge part 10 flees. The circumferential disk 70 has in the area the front plane 72 symmetrical to the step 74 two Indentations 75 of circular, approximately in diameter the shape corresponding to the pin 30. The indentations 75 give space for the pin 30, so that this if possible comes close to paragraph 24. In the embodiment 26 is a pin according to FIGS. 11 to 13 chosen, the issued locking element 54 in in the manner shown in FIG. 26 behind paragraph 24 can grab. At the beginning of the indentation, the locking element 54 through the recess 21 in the cross-sectional outline of the pin 30 pushed back and jumps upon reaching paragraph 24 by itself in the locking position in front. This embodiment differs in this respect not functionally from the previous ones Embodiments.

The step plate 70 provides an additional one Safety function. Care is taken to ensure that the level 74 always directed against the other part of the tape is what is about when you open the wing 2 space for reaching the locking element 54 of the pin 30 by means of a tool W. access Z creates. The tool W must be on the Step 74 are guided along, as can be seen from Fig. 25 is.

25 from below, however, is in the reproduced Position of the step plate 70 access to the Locking element 54 is not possible because of the in front of it further back, through level 73 limited part of the step plate 70 is blocked. The Stepped washer 70 must therefore always have a certain predetermined value Rotary position can be installed when the safety function should be given, which is a pushing back of the Locking element 54 from below the frame hinge part 10 (according to FIG. 25) should make impossible. It is possible Push back only from above with the sash open. The same applies to the wing hinge part 20.

The step plate 70 is in the additional recess 71 pressed in so that it is not lost. she sits pretty tight in recess 71. If that Band part can be used for another stop side you can change the direction of step 74 using a tool can be changed, which in an inner polygon 76 the step plate 70 engages and by means of which the Step disc, 70 can be rotated in the recess 71 can.

29 to 35 is another embodiment shown, in which the pin 30 as a plastic injection molded part is formed and at the upper end in the T-groove 17 of the cover piece 12 engaging head 18th having. At the top of the pin 30 are on the circumference of the Pin free-standing, axially parallel, at the end with a outer projection provided tongues 84 which ensure that the pin 30 is tight in the recess 21 sits and cannot be lost.

In the lower area of the pin 30 there is a transverse recess 85 formed in one to the transverse direction vertical plane going through the axis of the pin 30 has a substantially rectangular cross section. Somewhat below the transverse recess 85 is approximately the same flat transverse shaft 86 is provided. In the cross recess 85 and the transverse shaft 86 is one as a whole with 90 designated locking member slidable. On a guide part slides from the bottom 87 of the transverse recess 85 88 of inverted T-shaped cross section. The Guide part 88 is thus with the outside of the crossbar 89 on the floor 87 with the outer edges 91 are guided on the side walls of the transverse recess 85 (Fig. 35). The web 92 of the guide part 88 extends up to the upper limit 93 of the transverse recess 85. The guide part 88 is thus in the transverse recess 85 in the Transverse direction of the pin 30 guided.

From the right edge of the guide part in the figures 88 is an extension 94 below the guide part 88 bent, which engages in the transverse shaft 86 from the outside and merges into a wave spring 95 that turns on Abutments 96 at the left end of the transverse shaft in the drawings 86 supports. So the wave spring exercises when it is compressed, the locking member 90 after force driving out from the transverse recess 85 on the right out. On the opposite side of the right margin of the guide member 88 latch arms 97, 98 are bent up next to the web 92 of those located in FIGS. 29 to 35 above "Bottom" of crossbar 89 go out and one form still upward arch that steadily in the Arc of approach 94 merges, so that in the drawings right limit of the locking member 90 the right side forms a constant curvature. The locking arms 97, 98 run obliquely upwards so that they are resilient with their ends at the upper limit 93 of the transverse recess 85, such as 30 shows. Moreover the locking arms 97, 98 spread parallel to the crossbar 89 apart so that the angled outwards Ends 99, 105 of the locking arms 97, 98 on the side walls of the Apply transverse recess 85 under elastic tension.

In the upper limit 93 of the transverse recess 85 adjacent region of the side walls of the transverse recess 85 are attached as a whole with 101 trained guide cams, those with protrusions 99 and 105 in the below explained way according to the "ballpoint pen principle" interact.

29 shows the initial phase. The Locking member 90 is in the stable intermediate position, in which its domed right end little about the circular cross-sectional circumference of the pin 30 stands out. The projection 99 hangs behind a hook 102 of the guide cam 101 at a distance from the upper limit 93.

If now the pin 30 on the cover 12 in the Recess 21 is to be inserted, meets the upper one Edge first on the curvature of the neck 94 (Fig. 29). This curvature is dimensioned so that with something elevated Insertion pressure of the locking member 90 according to FIG. 29 is shifted to the left until the one on the right in the drawing The apex of the curvature is in the circular cross-sectional circumference of the pin 30 has disappeared (Fig. 30). there the projection 99 comes from the hook 102 which holds it in the 29 held stable, intermediate position, free and comes to rest at the upper limit 93. The wave spring 95 is maximally compressed.

In this state, the pin 30 can pass through the recess 21 are passed through until paragraph 24 passes is. The locking member 90 jumps under Effect of the wave spring 95 to the right out of the Transverse recess 85 out, as shown in Fig. 31 is. The top 97 of the locking member 90 or the locking arms 97, 98 belonging to it (97, 97 'in FIG. 31 visible) forms an angle with the axis of the pin 30 of almost 90 °, so that the locking member is pushed away 90 in the transverse direction when pulling on the pin 30 is not possible, unlike when pushing in the pin 30. The position shown in Fig. 31 is therefore the Locked position, that is the normal operating position of the pin in which it is the cover piece 12 non-removable holds in the groove 14.

If now in one of the rarely occurring needs the locking member 90 must be released again is shown with the tool shown in broken lines in FIG a pressure similar to FIG. 2 against the Curvature of the locking member 90 exercised. It glides the projection 99 of the locking arm 97 on the wedge-like inclined outer boundary 103 of the hook 102 along, whereby the end of the Locking arm 97 in the manner shown in FIG. 32 is bent inside. If you press in further, the Projection 99 over the hook 102 and snaps into the 29 again behind the hook 12 on. 33 is a phase shortly before reaching this State shown. Move it in again the projections 99, 100 from the stable intermediate layer 29 starting from a slope 104 (Fig. 34) forced inner web so that it is on the hook 102 can move on to the outside. Fig. 34 accordingly represents an intermediate phase between Fig. 29 and Fig. 31.

The purpose of this embodiment is one stable intermediate position of the locking member 90 to generate from which it when pressing the pin 30 into the Recess 21 removed independently without further action can then be in the locking position of FIG. 31 project. The locking piece 90 thus contributes to Simplification of assembly without giving up other functions at.
