Abstract

The display device, comprises a support arm (10) for the goods detachably fitting by push-fit coupling onto locally fixed part of wall plate (30) or similar. A radial projection (41) on one side and a complementary radial recess (42) on the other are formed at least one contact point between the plug which fits on the support arm end and the socket (35) in the wall plate. On pushing in/drawing out the plug the radial projection and recess form the two interconnecting closing halves of a press-stud type connector. At least one half is elastically deformable. The plug comprises two axial sections (15, 27) with different shape resistance so that one part is rotationally secure in the socket and the other forms the closing half of the snap fit connection.

Description

The invention relates to a device in the preamble of Claim 1 specified type. On a stationary part of the sales facility, like a wall plate, a bevy of support arms Detachably fasten in any desired arrangement pattern using plug-in couplings. Such plug-in couplings consist of a socket with a non-circular profile and a connector with a complementary counter profile.

In the known device of this type (DE 31 43 460 A1) Plugs mounted on a vertical pillar of the sales facility while the bushings are part of the support arms to be coupled therewith. When plugged in the non-circular design of the plug and the socket ensures that torsional loads on the support arm cannot have an effect; they are transferred to a column that carries the plugs. The support arms can be quickly and easily via such a plug-in coupling Mount with the wall plate or a wall-side column or again remove, but the safety of the plug-in coupling is endangered. As easy as plugging together the components of a plug-in coupling , it can also loosen axially in the opposite direction.

In devices of another type (DE 94 07 340.6 U1) a one-way connection between the support arm and a wall plate belonging to the sales facility has been used. With this one-way connection, the aforementioned unintentional loosening of the known plug-in coupling is avoided, but there are considerable further disadvantages. The two coupling parts of a one-way connection work together in the manner of a "bayonet lock". The coupling part seated at the end of the support arm consists of an axial bolt with an end transverse pin, a coil spring enclosing the bolt in the section in front of it, which is supported at one end on a plate and at the other end on the cross pin. On its side opposite the insertion opening of the bolt, the bushing has a disk with an opening, the opening profile of which corresponds to the cross-sectional profile of the bolt with the transverse pin attached to it. In a first step, the pin is first inserted axially into the bushing and guided through the opening in its cross pin. The helical spring is supported on the inner surface of the disc and is tensioned during the axial movement of the bolt. After the passage of the cross pin, the support arm must then be rotated by 90 ^o in a second step, as a result of which the cross pin seated on the bolt moves into a position offset in relation to the opening profile of the opening in the disk. If the support arm is then released, the helical spring relaxes and pulls the cross pin against the outer surface of the disc, where it retracts in a groove that secures this rotational position. By axial forces acting on the support arm, the one-way connection cannot be released; however, cumbersome handling is required for this. To do this, in reverse order of movement, the support arm must first be pressed axially while increasing the spring tension until the cross pin disengages from the groove in the washer, whereupon the support arm must be turned back until the cross pin is again in alignment with the opening profile of the breakthrough in the pane. Then the axial pull-out movement and uncoupling of the support arm is only possible.

The disadvantage of this known one-way connection between the support arm and Socket is the cumbersome handling when coupling and uncoupling. Another disadvantage is that the bolt of a coupling part only at its innermost end in the breakthrough of the disc supports, but in considerable part of its axial length lateral play to the inner surface of the socket is arranged. By high Radial loads on the support arm can result from the one-way connection move the coupled bolts in the bush radially because of the tensioned coil spring yields elastically. The support arm is bent.

A large-area support of the bolt in the sleeve is missing, which the Transmission of high forces would allow.

The invention has for its object a heavy-duty device to develop the type mentioned in the preamble of claim 1, the is inexpensive to manufacture and in which the plug connection between the Support arm and the wall plate is reliably engaged. This is according to the invention by the measures listed in the characterizing part of claim 1 achieved, which have the following special meaning.

After inserting the plug into the socket, an undesirable axial release of the plug-in coupling through the snap-type snap connection guaranteed. The required closing halves can be through radial projections on the one hand and complementary radial recesses on the other hand, simple and inexpensive already during the manufacture of the plug and generate the socket. The support arm is still highly resilient because the connector consists of two different sections, one of which only one is elastically deformable and to form one closing half serves the snap connection. The other section is dimensionally stable and ensures a rotation-proof holder when inserted in the socket. Between the dimensionally stable section of the plug and the There is a large-area support, the high forces is able to transmit.

In a longitudinal sectional view corresponding to FIG. 5, the coupling case of the finished device, analogous to FIG. 1, but with the support arm being indicated by dashed lines. The position of the individual components of the device relative to one another can be seen from this. This applies to both exemplary embodiments.

The device according to the invention consists, as can best be seen in FIG. 2 is recognizable from two, each for pre-assembled modules, of which the one assembly to a support arm 10 and the other assembly belong to a wall plate 30. In the drawings is the wall plate 30 represented by a fragment. This wall plate 30 is a component a sales facility. Instead of a wall plate 30, anyone could use another fixed part of a sales facility, e.g. Legs Pillar or a wall.

The cross section of the support arm is a flat profile 11 and is, as can be seen 1 to 3, used in portrait form. If necessary, edge cuts are made 12 embedded in the flat profile 11, in which, for example, the hook can be hung from hangers. The one at one end of the arm 13 provided end face can be attached to an end plate 14, for. B. by welding or soldering. Such a support arm 10, which is shown in FIGS. 8 to 12 is only indicated by dashed lines, can run straight or obliquely or be graduated.

The support arm has a detachable attachment to the wall plate 30 10 at the inner arm end 13 a plug 20 which, in the first exemplary embodiment, as evidenced by the end views of Figures 9a and 10a, a longitudinal oval Profile 21 has. This profile 21 consists of two diametrical semicircular Narrow sides 22 by two parallel rectilinear broadsides 23 are connected. The flat profile 11 of the support arm 10 runs parallel to the major axis of the connector profile 21. The profile height of the support arm cross section 11 corresponds approximately to that in the present case Maximum diameter of the connector profile 21 between the two narrow sides 22.

According to the exploded view of Fig. 8, the connector 20 is in turn a unit consisting of two parts 15, 25 which can be plugged into one another first part is a metallic sleeve 15 which, opposite the support arm 10, sits on the inner surface of the end plate 14. After assembly 11, this sleeve 15 produces a dimensionally stable outer section from the connector 20, which is dimensionally stable.

The other plug part is a plastic insert 25, which is in one piece is, but in two formally and cross-sectionally different Structures pieces. The plastic insert 25 is solid and includes a slim core piece 26, which in the case of assembly into the interior 16 of the sleeve 15 engages. This is shown in Fig. 11. Then protrudes from the sleeve 15 an extension piece 27 out, which has an elastic inner portion determined by the connector 20. The cohesion of the two connector parts 15, 25 is done here by pressing and possibly also gluing. The squeeze Circumferential longitudinal ribs 24 on the core piece 26 are beneficial comes a located at the transition between the pieces 26, 27 Step in contact with the end face of the sleeve 15. This makes the installation depth the plastic insert 25 set in the sleeve 15. The extension piece 27 forms an elastic inner section of the plug 20, the one closing half 41 of a push button-like to be described in more detail Snap connection 40 generated. For this are on the extension piece 27 still take the following precautions.

The plug 20 has a locking half on its inner end 28 Radial projection 41, while in the axially in front zone Fig. 11 recognizable cross-sectional taper 43 is present. At the transition to Radial protrusion 41 then creates an important one for the snap connection 40, closing shoulder 44. This cross-sectional taper 43 arises in the present case by a regionally conical course of the Plug in the extension piece 27 of the insert 25. This conical course comes essentially, as can be seen from Fig. 10a by dashed lines only on the aforementioned narrow sides 22 of the profile 21. This results in a bead shape of the radial projection 41 in the peripheral region of the two narrow sides 22. In the middle piece in between the profile 21 has an axial cutout 45 which is open towards the inner end 28 is. As a result, the inner end 28 bifurcates into two legs 29, which bear the radial projections 41 and when used as intended the snap connection during insertion 52 of the plug into the Bush 35 (Fig. 12) or when pulling out in opposite directions, against each other can spring.

The components of the device belonging to the wall plate 30 are at first embodiment, can be seen from FIGS. 4, 5, 6a and 7a. Of the The most important part of it is first a socket 35, which is evident 6a also has a longitudinal oval profile 31 which conforms is formed to the above-described connector profile 21, which is why the corresponding reference numerals for the profile parts, which can be seen from FIG. 9a can be used. The socket profile 31 can be used as an outline Connector profile 21 can be viewed. The wall plate 30 is, as can be seen 3, provided with a bore 32, which also profiles longitudinally oval is and for receiving a relatively small outer end piece 33 of the socket 35 is used. This installation depth 33 results from a Flange 34, with which the socket on the rear wall 36 by screws od. Like. Can be attached. For this purpose, the flange shown in Fig. 6a has 34 suitable, e.g. B. Screw receiving holes 37.

The socket 35 carries the other closing half 42 of the one already mentioned Snap connection 40. For this purpose, the socket has one opposite its inner end 38 axially recessed dent 46, which in the present case, as Fig. 6a reveals at the two rounded narrow ends 22 of the socket profile 31 is arranged. The dents 46 consist of crest-side impressions in the area of the narrow sides 22 of the profile 21, the inner flanks 47 limit the relevant die-shaped closing surfaces and one Create radial recess 42 towards the inner end 38 of the socket. This radial recess 42 is the complementary to the radial projections 41 described above Closing half of the snap fastener 40. The radial projections 41 thus produce the associated male-shaped ones Closing surfaces. The engagement position of these closing halves 41, 42 is shown in Fig. 12 recognizable.

As shown in Fig. 4, the socket 35 is in the wall bore after its attachment 32 with its outer socket end face 39 in a free axial Distance 18 to the face 17 of the wall plate 20 is arranged. This distance range 18 can be used to assemble a cover ring 50. The aperture ring 50 also conforms to the longitudinal oval bore 32 already mentioned oval profile 51 and can be, although formed in one piece, divided into two axial sections, as from Fig. 4 can be seen. The cover ring 50 comprises an end flange 48, which bears against the wall face 17 in the assembly case according to FIG. 5. At the End flange 48 is integrally formed on a tube extension 49, which in the above-mentioned axial distance region 18 in front of the socket 35 in a form-fitting manner intervenes. A press fit is provided. To promote that, serve Circumferential ribs 19 which settle in the wall of the bore 32. The Surface of the blend ring 50 can, according to the respective taste Wish to be painted or galvanized.

Fig. 2 shows the pre-assembled wall-side and arm side Assembly. The two modules are connected by a simple, axial insertion movement illustrated by arrow 52 in FIG. 2. All that is needed is the plug 20 in the opening of the blind ring on the view side 50 to be introduced. The full clutch position results from Fig. 12. The socket interior 53 shown in FIG. 4 takes the plug 20 accordingly Fig. 11 on. The tube extension 49 of the blind ring 50 extends the socket receptacle 53. When plugged in takes the inside of the socket 35 and the tube extension 49 of the blend ring 50 which extends it and is dimensionally stable Outer section 15 of the connector 20 in its entire length. By the large-area positive connection can withstand high radial forces be transmitted. Because of the non-circular interlocking profiles 21, 31 is the support arm 10 provided with the connector 20 against rotation stored in the socket 35.

The installation depth of the plug 20 is determined by the end plate 14, the as a stop on the front surface of the end flange 48 of the blind ring 50 comes to the plant. With this insertion movement 52 also come two aforementioned closing halves 41, 42 of the snap connection 40 in Intervention. As is apparent from Fig. 12, they engage behind on the two legs 29 provided shoulders 44 on the connector 20 the inner dent flanks 47 in the socket 35.

To decouple the support arm 10 only an axial pull-out movement is required of the plug 20 to be executed from the socket 35, the in the opposite direction to arrow 52 of FIG. 12. But that's only possible when such an axial pull-out force is exerted that it to a deformation of the two closing halves 41, 42 described above the snap connection 40 comes. This deformation essentially exists in that the two end plug legs 29 so far radially be moved against each other until the radial projections on the plug side Snap 41 over the inside constrictions of the two dents 46 and release them.

6b and 10b are, in a modification of the first embodiment differently formed, non-circular profiles 31 ', 21' of the socket 35 and the Plug 20 shown. These are rectangular profiles 21 ', 31', which have essentially rectilinear narrow sides 22 'and broad sides 23'. The corner areas 54 can be rounded. Instead of dents here has the bush 35, as can be seen in FIG. 6b, two beads 46 ', that face each other and point inwards. These beads 46 ' leave in a similar manner to that in the previous embodiment dents 46 described the matrix-shaped closing surfaces in the socket 35 arise. In other respects, the components in this second one Embodiment analogous to that of the first embodiment trained, which is why the description so far applies.

FIG. 9b shows an end view analogous to FIG. 9a and to the second Embodiment belonging components. Suffice it to the differences enter into; in all other respects the previous one also applies in this case Description. First it can be seen that on the back of the in Fig. 9b shown end plate 14 'arranged a metallic sleeve 15' which is a rectangular cross section analogous to the profile 21 'of FIG. 10b shown connector 20 has. In this case, the outline of the End plate 14 'a rectangular format.

In Fig. 7b is the top view of that in the second embodiment used blind ring 50 'shown, which in use that of the first embodiment shown in Fig. 7a replaced. Here, too, it is sufficient to only consider the differences. This consist essentially in that both the end plate 48 'has a rectangular outline 51 'and the integrally formed tube extension 49' have a rectangular cross section have. The opening cross section 55 is that of bushing 35 shown in Fig. 6b coincident. It is therefore also in the case of this second exemplary embodiment, the assembly from FIG. 12 apparent conditions.

It goes without saying that instead of the described profiles 21, 21 'and 31, 31 'also any other, preferably non-circular cross-sections for the plug 20 and could be used with the socket 35. As profile shapes squares, triangles, star cross sections and polygons would also be possible, like trapezoidal or dragon shapes.
