Definitions
- the invention relates to a device of the type defined in the preamble of claims 1 and 2 and a method for producing a fitting or fitting part intended for such devices, which has a receiving opening and a transverse bore extending transversely thereto.
- fittings or fittings is to be understood in particular fittings such as handle or handle parts for doors or windows and sanitary fittings such as the holding arms of two-part towel holders, lower parts and top caps of soap dishes, toothbrush holder, shelves or the like. All these parts have in common that they each have a first part with a receiving opening and a second part, which either contains a segment that can be inserted into the receiving opening or from a segment that can be inserted as a whole into the receiving opening in the form of a wall or the like a lower part or the like, which is covered by a first part in the form of an upper part or the like or enclosed on all sides.
- the fastening device is designed in such a way that the locking pin engages in the transverse bore in the connected state of the two parts and, if necessary, holds the two parts together with a positive fit. Detachment of the two parts from one another is possible in that the locking pin is pressed out of the transverse bore by means of a tool inserted from the outside.
- the invention is therefore based on the object to design the fastening device of the type described in such a way that the manufacture of the transverse bore is facilitated.
- a method for producing the transverse bore having the locating bore is to be specified, which enables the fittings and fittings to be manufactured from injection molding in a simple manner.
- the transverse bore is formed in the filler or is limited by this.
- This has the essential advantage that its inner portion does not come from the inside, i.e. must be attached from the receiving opening, which is more difficult the smaller the diameter of the receiving opening.
- the method according to the invention has the advantage that, in the manufacture of the fitting or fitting parts having plastic from the receiving opening by injection molding, no complex tools with movable parts which enable removal from the mold are required. Normally, two core halves would have to be inserted into the receiving opening during the spraying process, one of which has a projection corresponding to the inner section of the transverse bore, and after the spraying process the first smooth core half and then the second core half having the projection would have to be pulled out of the receiving opening .
- FIG. 1 shows a fastening device according to the invention on a pair of door handles which has a first handle part 1 with a receiving opening 2 and a second handle part assigned to it, of which only one segment in the form of a handle mandrel 3 is shown in FIG. 1, which is connected in some way to the pusher part, not shown.
- the pusher mandrel 3 has a square cross section and can be inserted into the receiving opening 2 with a corresponding cross section with close tolerance.
- the presser mandrel 3 For releasable attachment of the presser mandrel 3 to the presser part 1, the latter has a locking pin 4 at its free end, which is slidably mounted in the presser mandrel 3 and with one end protrudes into an opening 5 of the presser mandrel 3, in which a compression spring 6 is also mounted, which tries to push the locking pin 4 outwards.
- the end of the locking pin 4 projecting into the opening 5 has a cross-sectional widening which prevents the locking pin from being pulled out completely from the presser pin 3.
- the length of the opening 5 and the length of the part of the locking pin 4 projecting outward from the surface of the presser pin 3 in the normal position according to FIG. 1 are dimensioned such that the locking pin 4 is pressed so far into the opening 5 against the pressure of the compression spring 6 can that its outer end is flush with the surface of the press mandrel 3.
- the handle part 1 has, in its grip, the axis of which is essentially horizontal in FIG. 1, a steel insert 8, to which a sleeve-like filler 10 is welded along a weld seam 9 and which encloses the receiving opening 2 in the manner of a sleeve or cup.
- the filler 10 has a transverse bore 12 running perpendicular to its axis 11 and parallel to the axis of the handle, which has an inner section 14 bordering the receiving opening 2 with a cross section corresponding to the outer cross section of the locking pin 4 and one to the Has inner section and the outer surface of the pusher part 1 bordering outer section 15 with a significantly smaller cross section than the inner section 14.
- the pusher mandrel 3 is arranged with respect to the receiving opening 2 such that the locking pin 4 engages in the inner section 14 after the pusher mandrel 3 has been inserted, thereby connecting the two pusher parts to one another without play.
- a release of this connection is possible in that a steel pin with a small diameter is inserted from the outside into the outer section 15 of the transverse bore 12 and pressed in until the locking pin 4 has emerged from the inner section 14 and, as a result, the presser pin 3 from the Receiving opening 2 can be pulled out.
- the filler 10 and the steel insert 8 are encapsulated on all sides with a jacket 16 made of plastic.
- the filler 10 is first produced and welded to the steel insert 8, if one is provided.
- a bore 17 running perpendicular to the axis 11 is formed in the filler piece, which completely penetrates the wall section of the filler hole opposite the transverse bore 12 in FIG. 3, but only in the wall section of the filler piece 10 having the transverse bore 12 in FIG. 3 forms a blind hole, which is open in accordance with FIGS.
- the filler 10 and the steel insert are now, as shown schematically in FIG. 3, placed in an injection mold 18, and the free end of the receiving opening 2 is plugged onto a core 19 of a corresponding cross section, which holds the filler and at the same time the receiving opening 2 and covers the bore 17. Then the filler 10 and the steel insert 8 are encapsulated with liquid plastic, which penetrates into the mold cavity 20 of the mold 18 and consequently also from the outside into the bore 17.
- the inner section 14 of the transverse bore 12 remains free of plastic, since on the one hand the receiving opening 2 is filled and on the other hand the inner section 14 is closed at the rear end by the thin wall section 21.
- the outer section 15 of the transverse bore 12 is finally produced by drilling through the wall section of the jacket 16 obtained during the injection molding and the wall section 21 from the outside.
- the transverse bore 12 is preferably not, as would be customary per se, on the lower side of the handle part 1 during assembly on the door, but in a central section near the inner arch. This has the advantage that the position of the transverse bore 12 is independent of whether it is a right-hand or left-hand lever part, which considerably simplifies the storage and offers significant advantages, especially in the case of combinations of lever parts and buttons or differently colored lever parts.
- the procedure according to FIG. 4 is preferred, which shows a pusher part 22 in a position rotated by 90 ° compared to FIG. 1.
- the pusher part 22 has a receiving opening 2, a filler 10 and one Plastic jacket 16 on.
- the axis of an inner section 23 of the transverse bore is arranged both perpendicular to the axis 11 of the receiving bore 2 and perpendicular to the axis 24 of a handle part of the handle part 22.
- a plug 26 which is made of metal or another material which does not bond with the plastic to be encapsulated is inserted into the bore 25 corresponding to the bore 25 according to FIG. 3, so that the bore 25 is not filled with plastic can be.
- the outer section of the transverse bore can either be attached from the right analogously to FIG. 3, in which case the inner section 23 and the subsequently attached outer section form the transverse bore. Or the outer section is drilled from the left in FIG. 4 through the wall section opposite the bore 25 until the bore 25 is reached and the plug 26 can be knocked inward and removed through the bore thus created.
- the transverse bore cooperating with the locking pin 4 consists of the bore 25 forming the inner section and the subsequently drilled outer section. The subsequent attachment of the outer section thus takes place in this embodiment depending on the type of door for which the handle part 22 is to be used.
- the fastening device described can be used analogously to the connection of fitting parts in the form of push handles 27, 28 for a door 29, in particular a glass door (FIG. 5).
- the first push handle 27 has a sleeve or cup-like filler 30 with a receiving opening 31, which is surrounded by a sprayed-on plastic jacket 32 and has an annular groove 33 at the end facing away from the door, which prevents the jacket 32 from Filler 30 can be deducted.
- the push handle 27 is provided with a transverse bore 34 which has an inner section 35 with a comparatively large and an outer section 36 with a comparatively small inner cross section.
- the inner section 35 is formed in the wall of the filler 30 in the manner of a blind bore.
- the second push handle 28 contains a sleeve or cup-shaped filler 37, which is surrounded by a sprayed-on plastic jacket 38 and has an annular groove 39 at the end facing away from the door 29, which prevents the jacket 38 from being pulled off the filler 37 .
- a fastening screw 40 is screwed into the filler 37 from the other side of the door, which has a threaded section arranged in the filler 37 and a thread-free section 41 which projects through the door 29 and a centering sleeve 42 inserted into its bore in the assembled state of the push handle 28 Hexagon head 43 carries and is extended beyond this.
- a locking pin 44 is mounted, which corresponds to the locking pin 4 according to FIG. 1 and, in the assembled state, engages in the inner section 35 of the transverse bore 34.
- the assembly of the two push handles 27 and 28 begins with the push handle 28 being attached to the door 29 in the manner shown in FIG. 5. Then the fastening screw 40 is screwed on from the other side of the door until there is a tight fit of the pull handle 28 and the section 41 assumes such an angular position that when the receiving opening 31 is pushed on, the locking pin 44 can snap into the inner section 35 of the transverse bore 34.
- either the threaded section of the fastening screw 40 and / or the associated receiving part of the filler 37 and / or the centering sleeve 42 are sufficiently deformable and, for example, made of slightly resilient plastics.
- the receiving opening 31 is pushed onto the section 41 until the locking pin 44 engages, so that the two push handles 27 and 28 are firmly connected to one another, but can be separated from one another again by inserting a steel pin or the like into the outer section 36 of the transverse bore 34.
- Checking the correct angular position of section 41 includes possible that the receiving opening 31 is widened at its outer end to a hexagon hole that only fits the section 41 on the hexagon head 43 when the position is correct.
- the first arm 46 has a receiving opening 48 which is surrounded by a filler 49 in the form of a hollow cylindrical sleeve which is fastened in a central bore 50 of one end of the arm 46 and a section which projects outwardly beyond this end which is rotatably arranged in a coaxial bore of a lower part 51.
- the lower part 51 is fastened to a wall or the like by means of screws 52 passing through screw holes and covered with an attached cover cap 53 which has corresponding bores for receiving the filler 49.
- the end of the second arm 47 facing the first arm 46 has a central bore 54, into which a cylindrical mandrel 55 is inserted, which has a section which projects beyond the end of the arm 47 and which represents a segment which can be inserted rotatably into the receiving opening 48 its outer end carries a locking pin 56 corresponding to the locking pin 4 of FIG. 1.
- this locking pin 56 snaps behind that located in the arm 46
- a trailing edge of the filler 49 in a free space 57 which is formed at this point by the central bore 50 of the arm 46, which is slightly extended beyond the trailing edge and which represents an inner portion of a transverse bore arranged transversely to the axis of the receiving opening 48.
- the wall of the arm 46 opposite the locking pin 56 has a bore 58 with a small cross-section compared to the locking pin 56, which together with the free space 57 Cross-section must at least correspond to the cross-section of the locking pin 56, forms a transverse bore which corresponds to the transverse bore 12 according to FIG. 1.
- the inner section of the transverse bore can be produced with simple means and no complex measures are required when the arm 46 is injection molded.
- the lower part according to FIG. 6 has a length of the locking pin 56 adapted longitudinal groove 72.
- the invention is not restricted to the exemplary embodiments described, which can be modified in various ways.
- the embodiments according to FIGS. 1 to 5 it is also possible to first produce the plastic sheath 16 or 38 of the fittings or fittings using the injection molding process and then, analogously to FIG. 6, the filler pieces 10 and 30 subsequently in the finished sheath insert and glue, screw or otherwise secure.
- This has the advantage that no blind bores need to be provided in the filler since the bores can pass through, and that the outer sections of the transverse bores can be formed in the outer plastic jacket of the parts during the spraying process, i.e. do not need to be drilled.
- simple injection molds can be used.
- filler pieces made of metal or steel so that the function is retained even in the event of a fire, which is particularly important when the fittings according to the invention are used on fire protection doors.
- a cap placed on the bore 25 can be provided, which only needs to be drilled through after the filling piece 10 has been encapsulated.
- the locking pin is pressed into the transverse bore by a small compression spring 6.
- the spring force of this compression spring 6 cannot be chosen arbitrarily large due to the mostly narrow spatial conditions, the locking pin can often be pushed back with little force, so that the anti-theft device caused by the outer section 15, 36 of the transverse bore is not always considered sufficient.
- the two fittings or fittings are braced against one another by at least one spring element in such a way that the locking pin is arranged in the transverse bore after the two parts have been clamped.
- Fig. 5 shows such an additional anti-theft device by means of a coil spring 45, which is arranged in a recess on the door-side end of the first push handle 27 and one end of which is supported on the door 29, while the other end on a shoulder delimiting the recess on the end remote from the door of the push handle 27.
- the push handle 27 in order to allow the locking pin 44 to snap into the transverse bore 34 without friction, is first pressed against the door 29 during assembly and then released after the locking pin 44 has been locked in place.
- the helical spring 45 then pushes the push handle 27 away from the door until the locking pin 44, after overcoming the slight radial play between it and the transverse bore 34, presses against the wall delimiting it.
- the locking pin 44 can then only be pushed back with considerable effort. With knowledge of the secret, on the other hand, a small amount of force is sufficient if at the same time the push handle 27 is pressed against the door and the clamp seat of the locking pin 44 is thereby loosened.
- each first part in each case has a receiving opening into which the second part is wholly or partly inserted
- the first part could be provided with two or more receiving openings and each receiving opening with a second part or two Allocate segments of a single part.
- the upper part of a shelf, a towel holder or a toothed glass holder, for example, could be provided on its back with two receiving openings, each of which is placed on a plug-like or block-like segment attached to the wall and fastened to it by means of the fastening device according to the invention.
- Each of these segments forms a part that is inserted as a whole into the receiving opening.
