Description

05

The invention relates to a fitting for holding one end of a slat of a slatted frame according to the preamble of claim 1.

Such a fitting is described in DE-GM 90 03 848.

The generic fitting has a support fitting part, which is guided on a base fitting part in a vertical direction when installed. Two locking arms are formed on the support fitting part or the base fitting part via two bending sections, which have locking lugs that work together with two sets of locking grooves on the base or support fitting part. A blocking slide can be inserted between the facing, inner boundary surfaces of the locking arms in order to hold the locking arms in a force-fitting manner in the position of the locking lugs that are positively seated in the locking grooves. In this fitting, the gripping section of the blocking slide is arranged transversely to the longitudinal direction of the slats and is not directly accessible for operating the blocking.

The object of the present invention is to develop a fitting in such a way that its locking mechanism can be operated more easily.

This object is achieved according to the invention by a fitting according to claim 1.

In this fitting, the gripping section of the blocking

AUN.219-025 - 2 -

5188.7 ··· -* 2 -....:.. ..*·..· 10.12.1996

The slider is arranged in such a way that it can be easily grasped through the gap between two slats covering the fitting and pulled vertically upwards from a lowered blocking position into a release position in which the fitting can be adjusted. Since the gripping section runs in the direction of the frame longitudinal beam, it is easily accessible from the outside through a gap between the slats, even when a mattress is placed on top.

Advantageous further developments of the invention are specified in the subclaims.

The further development according to claim 2 is very easy to manufacture and is suitable for numerous designs of frame longitudinal beams.

The development of the invention according to claim 3 reduces the protrusion of the gripping section over the longitudinal frame beam, particularly when the upper side of the longitudinal frame beam is slanted.

A fitting according to claim 4 has no protrusion of the gripping section beyond the longitudinal frame beam, so that the lying comfort is not restricted and the safety of the fitting is increased.

The fitting according to claim 5 has a blocking device which is particularly compact and safely guided.

The further development according to claim 6 enables a safe guidance of the blocking slide without additional components.

According to claim 7, the blocking section is designed in such a way that it can be moved particularly securely into its blocking or release position without the risk of being pulled out too far

5188.7 · ^; · -&iacgr; 3 -.&Ggr;..:.."··..· 10.12.1996

is movable.

The further development according to claim 8 enables a safe switching of the locking device without elements being added to the blocking slide.

The development of the invention according to claim 9 makes it possible for the release position and the blocking position of the blocking slide to always be the same, regardless of the setting of the fitting with respect to the longitudinal frame beam.

In a fitting according to claim 10, guide screws serve simultaneously to guide the adjustable fitting part and to hold the fitting parts together in an easy-to-assemble unit.

The further development according to claim 11 enables a secure fixing of the guide screw with a small thickness of the fittings.

The further development according to claim 12 enables a particularly secure fastening of the fitting in the longitudinal frame beam through the spreading effect of the beam pin. 25

The development of the invention according to claim 13 enables a connection of the supporting fitting part and the base fitting part, without increasing the thickness of the fitting.

The invention is explained in more detail below using an embodiment with reference to the drawing. In this drawing:

In Figure 1, one of the longitudinal beams of a slatted frame is designated with 10, and this carries a fitting, designated overall with 12, for supporting two slat ends 11. The slat ends 11 extending perpendicular to the plane of the drawing in Figure 1, as well as a rubber-elastic bearing element 13, by means of which the slat ends 11 are supported on the fitting 12, are only shown in Figures 2 and 15 and only in dash-dotted lines for the sake of better clarity.

The fitting 12 comprises a fixed base plate 14, a support plate 16 that can be adjusted vertically thereon and a blocking slide 44.

The base plate 14 is shown in Figures 4 to 9 even further

5188.7 ··· -» 6 -.I..!.. ..·*..' 10.12.1996

shown in detail.

The base plate 14 has a main body 17 which, on its side facing the longitudinal beam 10, has two pins 18 which are perpendicular to the base plate 14 and have a slot at their protruding end. In practice, these pins are provided with an axial groove on the outside and are press-fitted into corresponding holes in the longitudinal beam 10. Through holes 19 are made in the main body 17 along the central axis of the pins 18.

The main body 17 has a rectangular recess 20 in its center, which is divided into two elongated, vertical openings by a guide rod 22 integrally formed on the top of the main body. Two guide ribs 24 and a rear wall 26 projecting downwards beyond the lower edge of the main body 17 are molded onto the main body below the recess 20, with the rear wall 26 in particular, as can be seen from Figures 5 to 8, being arranged in a plane set back from the main body 17. Locking arms 30 are integrally formed onto the guide rib 24 and rear wall 26 via a bending section, each of which has a transverse, horizontally outward-pointing locking lug 32 at its upper end.

The support plate 16 is shown in more detail in Figures 10 to 12.

0 The support plate 16 shown in Figure 1 essentially comprises two side parts 34 and 36, which are connected in one piece via a connecting wall 38. The connecting wall 38 is arranged offset to the rear in relation to the side parts 34 and 36, i.e. away from the base plate 14, 5 so that between the two side parts

5188.7 ...4 7 -.:..:.. ..·· · 10.12.1996

parts 34 and 36, a vertical channel 40 is formed. Fixed locking grooves 42 are formed in the side walls of the vertical channel 40, which are complementary to the locking lugs 32 of the base plate 14.

The width of the vertical channel 40 of the support plate 16 corresponds essentially to the distance between the inner vertical boundary surfaces of the locking arms 30 of the base plate 14, so that the support plate 16 with its vertical channel 40 is received on these surfaces in a vertically displaceable manner.

The blocking slide 44 is shown in more detail in Figures 13 and 14.

The blocking slide 44 is inserted with a blocking section 46 into a recess formed between the base plate 14 and the support plate 16 and laterally delimited by the locking arms 30. The blocking section 46 has a guide section 48 in its lower area, a locking section 50 in its upper area and a release section 52 between these two areas, the width of which is significantly smaller than that of the guide section 48 or the locking section 50. The blocking slide 44 also has a gripping section 54 which runs in a vertical plane essentially perpendicular to the frame longitudinal beam 10 in the direction of the frame longitudinal beam 10.

In Figure 1, the blocking slide 44 is shown in its blocking position. In this position, the outer sides of the blocking section 50 are in contact with the inner lateral boundary surfaces of the spring-mounted locking arms 530, so that the locking lugs 32 cannot be moved out of the

5188.7 ..*. -: 8 -.:..:.* I'·'· '· 10.12.1996

can be moved out of the complementary, fixed locking grooves 42 of the support plate 16, whereby a displacement of the support plate 16 is impossible.

In Figure 2, the blocking slide 44 is shown in an upwardly pulled release position: In this position, the blocking section 50 is moved upwards and instead the release section 52 is adjacent to the inner surfaces of the locking arms 30. As a result, the locking lugs 32 of the base plate 14 are no longer necessarily held in the fixed locking grooves 42 of the support plate 16. The locking arms can thus each bend inwards in a resilient manner via the bending sections 28, so that the locking lugs 32 can emerge from the fixed locking grooves 42 when the support plate 16 is moved upwards or downwards relative to the base plate 14.

In Figure 2, a gap can also be seen between the slat ends 11, the width D of which is greater than the width of the gripping section 54 of the blocking slide 44, so that the gripping section 54 can be gripped through this gap.

In Figure 3, the support plate 16 has been moved upwards. The blocking slide 44 is again in its blocking position, i.e. the locking section 50 of the blocking slide 44 is in contact between the inner surfaces of the locking arms 30 and thus holds the locking lugs 32 in the fixed locking grooves 42 corresponding to the upwardly moved position of the support plate 16, so that the support plate 16 is held immovably.

5 Reference is now made to Figure 4, in which the

5188.7 ...-9 -.:..:.. ..··..· 10.12.1996

Base plate 14 is shown individually. In addition to the parts described in Figures 1 to 3, two guide lugs 56 are also visible here, which serve to guide the blocking slide 44.

In the side view of the base plate in Figure 5 it is clear that the main body 17 with the recess 20 and the guide rod 22 are arranged in a different plane than the guide ribs 24 formed on this main body 17, the rear wall 26, the bending sections 28, the locking arms 30, the locking lugs 32 and the guide lugs 56. This is also clear from Figure 6.

Figure 7 shows a section along the line VII-VII of Figure 4. Here, a stop lug 58 can be seen, which works together with a recess in the blocking slide 44 described further below in Figure 13. The stop lug 58 is, as can also be seen from Figure 8, formed in the rear wall 26 between the two guide ribs 24 in the direction towards the longitudinal frame beam.

Figure 9 shows an enlarged detailed section along the line IX-IX of Figure 4. It can be seen that the bore 19 runs along the central axis of the slotted pin and completely penetrates it. In the area of the pin 18, however, the diameter of the bore 19 tapers so that the slotted pin 18 can be clamped to the bore in the longitudinal frame beam 10 by spreading it open 0 by screwing in a guide screw 59 (see Figure 16).

The support plate 16 is shown in detail in Figure 10. It has a substantially rectangular basic shape and comprises the two side parts 34 and 36 and the connection between the two side parts 34 and 36.

binding wall 38. A vertically extending long slot 60 is made in each of the side parts 34 and 36, and two fastening pins 62 are formed integrally on the side parts 34 and 36, each of which has a circular segment cross-section and points away from the frame longitudinal beam when installed. The fastening pins 62 are used to fasten the rubber element 13, which receives the slat ends 11. On the side of the support plate 16, which faces away from the base plate 14 when assembled, a countersink 64 is made on the peripheral edge of the long slot 60.

The blocking slide 44 is shown in Figures 13 and 14. It can be seen in particular from Figure 13 that in the area of the guide section 48 and the release section 52 a recess forming a lower stop 66 and an upper stop 68 is made in the blocking section 46, which in the assembled fitting 12 works together with the stop lug 58 visible in particular in Figures 7 and 8.

It can be seen from Figure 15 that the gripping section 54 of the blocking slide 44 is angled at an angle of approximately 75 to the axis of the locking section 50 and is selected to correspond to the noticeable inclination of the top of the longitudinal frame beam. In addition, a recess (not shown) can be present in the top of the longitudinal frame beam 10, in which the gripping section 54 of the blocking slide 44 lies essentially flush with the top of the longitudinal frame beam 10 in its blocking position. As can be seen from Figure 15, the main body 17 is embedded in the inside of the longitudinal frame beam 10.

In Figure 16 the guide screw 59 is shown in detail.

5188.7 ·&id;·-&id; 11 -»&Igr;..:!.* '.'.*'..* 10.12.1996

A head 72 of the guide screw 59 is so high and has such a diameter that it disappears in the recess 64 on the peripheral edge of the elongated slot 60 and therefore does not protrude beyond the rear side of the support plate 16.

A collar 74 of the guide screw 59 with a height corresponding to the thickness of the side parts 34 and 36 enables low-friction sliding in the long slot 60. Finally, the guide screw 59 has a threaded section 76 which can be screwed into the hole 19 and thus initially only connects the support plate 16 and the base plate 14 to one another in a captive manner, i.e. is not fully screwed into the hole 19. Only after the pins 18 have been inserted into the blind holes of the frame longitudinal beams 10 are the guide screws 59 screwed in further, whereby the pins 18 are spread and clamped to the blind holes.

As can be seen from the above description, the height-adjustable fitting according to the invention contains three one-piece plastic injection-molded parts (fitting parts 14, 16, blocking slide 44) with such a geometry that they can be manufactured in two-part injection molds without undercuts, and the guide screws 59, which are simple turned parts.

The assembly of the fitting, its secure attachment to a frame longitudinal beam and its height adjustment can be easily accomplished.
