Description

Sleeve and insertable arm as a hanging device

Field of application of the invention

The invention relates to a suspension device which consists of a sleeve received by a support structure and an arm which can be inserted into it and which is used for hanging articles or for holding a shelf. The items to be hung or placed on the shelf may e.g. trade goods offered. The device can be used individually as a fitting; with several such devices, e.g. populate a presentation area in a retail facility. The supporting structure comes e.g. a wall, a panel, or a movable stand.

State of the art

The device according to WO 01/43599 is intended for hanging articles or for holding a shelf and consists of a plug-in receptacle which can be inserted into a support structure and an arm which can be plugged into the plug-in receptacle. A passage extends into the plug receptacle from the front entry to a rear boundary. At the top, the passage has a bevel that rises upwards towards the entrance and thus creates an upper margin. At the bottom, the passage has an incline that slopes downwards towards the boundary and thus gives a lower margin. At the top of the passage there is an undercut that precedes the boundary in the direction of the entrance. The plug-in receptacle is designed as a horizontally attached profile rail or as a housing, which is, however, quite solid and voluminous. The arm has a tongue which can be inserted into the passage of the profile rail or the housing and which is provided with an upwardly directed hook which engages in the undercut.

Further constructions for inserting support arms into a receptacle are known from WO 99/20094. In the opening of a support structure, a receptacle is received, into which a support rod can be inserted. Alternatively, the support rod can be inserted directly into a hollow profile. The capsule-like receptacle is fixed in a panel and at the plug end of the support rod a hook contour is provided, which is used for fixing in the socket. In the first version, a cut-out shoulder is present in the insertion opening of the receptacle, which the hook contour engages behind after the arm has been inserted. When inserting, the arm is first angled to get behind the shoulder with the hook contour, whereupon the arm is lowered into the horizontal, so that the hook contour reaches behind the shoulder as much as possible. The socket has a mounting flange at the front and a threaded section at the rear. The receptacle is usually inserted into a panel recess so that the mounting flange is supported on the front of the panel at the edge of the recess. The protruding thread section is screwed to the rear of the panel with a lock nut. In the second embodiment, a spring element projecting into the insertion opening is arranged in the plug-in sleeve and engages in the hook contour when the arm is inserted.

Object of the invention

In an effort to further improve the known suspension devices, which consist of a sleeve that can be inserted into a support structure and an arm that can be inserted therein, the object of the invention is to create a device without spring elements, where arms with differently configured plug-in approaches are inserted into the same sleeve can be inserted in releasable locking. The background to this is the need to equip a single type of sleeve with arms of different load capacities and shapes.

Overview of the invention The device is used to hang up articles or to hold a shelf and basically consists of a sleeve which can be inserted into an opening in a support structure and an arm which can be inserted into the sleeve and which has a direct or indirect load-bearing function for the articles to be picked up. The sleeve initially has a freely ending rear part, which is preceded by a central part, which can merge into a flange lying in the foremost position. A channel, which in principle extends axially into the rear part, extends through the sleeve and opens out at the front if a flange is present within it. In the rear section there are counter contours that are accessible from the canal. The arm has a plug end, which faces the sleeve in the inserted state and continues in an approach, on which a complementary contour to the counter contours is present. The counter contours on the one hand and the fixing contour on the other hand are intended to work together. The plug end is opposite a front end that protrudes into the room when plugged in. The peculiarity of the device is characterized in that the countercontours each have different proportions in a first type and a second type and are present together in a sleeve and are adjacent to one another. The fixing contour on the lugs is designed in a first type and a second type and is alternatively provided on an arm. It is thereby achieved that the arm provided with the fixing contour of the first type at the base is releasably locked in the sleeve by inserting it at an angle to the horizontal when the front end is raised and then lowering the front end. The arm with the fixing contour of the second type at the base can also be detachably locked in the sleeve by axial insertion and twisting around the longitudinal axis.

Special embodiments of the device are described below: The first type of counter-contour in the sleeve is a recess extending from the channel in the radial direction. Complementary to this is the first type of fixation contour at the base of the arm, a nose which projects upwards when the arm is locked in the sleeve. The second type of counter-contours in the sleeve comprises at least one shoulder located internally. Complementary to this is the second type of fixing contour at the base of the arm, at least one segment projecting sideways in the state of the arm locked in the sleeve. The recess, as the first type of counter-contour, is designed as an opening through the wall of the rear part of the sleeve, a further recess of this type being preferably provided opposite the one recess. Internally there are two opposing shoulders, each shoulder being axially bounded on the one hand by the inner surface of the sleeve base and on the other hand by a bump edge, all of which together form the entirety of the counter contours. In the extension of the channel, there is a preferably circular recess in the base of the sleeve, which preferably extends outwards as an outlet. det. The two recesses are made as vertical, mutually congruent relative to the vertical eccentric grooves in the wall of the rear _portion, are formed whereby the opposing contours.

The channel is in principle of a rectangular vertical cross section and has bulges lying opposite one another on both side flanks, which complement one another in the vertical cross section to form a full circle. Thus, an approach of a rectangular cross section with the fixing contour of the first type or an approach of a rounded, preferably circular cross section with the fixing contour of the second type can alternatively be inserted into the sleeve.

The flange - if present - is circular or rounded or has a polygonal geometry and projects beyond the adjoining middle section in cross-section. There are external position warts on the middle section which serve to secure the rotation and precise alignment of the sleeve in the opening in the support structure, the opening being expanded with notches complementary to the position warts. The rear part has an external thread which is intended for screwing a securing flange screw from the rear of the supporting structure onto the sleeve inserted therein. The flange screw consists of a ring washer, a center piece arranged in the center and spokes connecting it to the ring washer. The washer can have screw holes for optional securing on the back of the support structure. The center piece has an internal thread which is complementary to the external thread of the rear part of the sleeve and is preferably equipped with an external polygon for attaching a tool. The opening in the support structure is provided on the front with a circular all-round countersink in which the sleeve flange rests.

The arm can alternatively be equipped differently, namely: a) with an attachment made of flat material with the fixing contour of the first type, the head of which is arranged most directly merging into the insertion end of the arm; or b) with an attachment made of flat material with the fixing contour of the first type, the foremost head of which merges directly into the plug end of the arm at the top and downwards into a support arm which, in the state of the arm inserted into the sleeve, touches down on the front of the supporting structure; or c) with an attachment made of flat material with the fixing contour of the first type, to the foremost head of which is connected a shaft which is connected to the plug end of the arm and which has a different cross section to the attachment, for example tubular or rod-shaped; or d) with an attachment made of rod material, preferably of round cross-section, with the fixing contour of the second type, this attachment connecting seamlessly to the plug end.

If the approach consists of flat material with the fixing contour of the first type, the elongated head has the following detailed features: a) on the upper side a basically horizontal ledge surface (32) that extends to a recessed free cut, in front of which the nose is in shape of an erect hook; b) as the upper end of the nose, a roof surface that lies above the level of the ledge surface; c) an underside of the head, which is formed as an inclined plane with an upward tendency towards the nose and merges into an arc on the nose in a basically vertical bridge of the nose.

This approach made of flat material is advantageously cut using a laser.

If the attachment consists of round material with the fixing contour of the second type, the following detailed features are available: a) first of all an end face, preferably chamfered, to which an end segment adjoins, which is in principle a narrow cylinder section; b) in the direction of the plug end, in front of the front segment, two wing-shaped segments protruding from the arm as a fixing contour, which are opposite each other with a 180 ° offset, thus run on the same plane and project beyond the cross section of the arm. In this approach, the individual segment is advantageously produced by means of a tool that deforms the bar material from two sides, as a result of which there is a recess in the form of a vertical recess above and below this segment, the material of which is shifted into the segment.

Two parallel spaced arms lying on one level can be bridged at their front ends by a fixed crossbar, whereby a U-shaped frame is created, the two approaches with the fixing contour of the first type are arranged in two sleeves arranged at the same height level in the support structure leave it plugged in.

When the arm is inserted into the sleeve and has an attachment with the fixing contour of the first type, the nose engages in the upwardly directed recess. Here, the depth of insertion into the channel of the sleeve is blocked by the nasal dorsum pushing against the inner surface of the base and the axial pulling out, without lifting the arm at the front end, by reaching behind the nose in the recess.

With the arm inserted into the sleeve, which is provided with an attachment with the fixing contour of the second type, the two segments of the fixing contour lie on the pocket-shaped shoulders after a rotation of the arm relative to the initial insertion position about the longitudinal axis by 90 °. Now the insertion depth into the channel of the sleeve is blocked by pushing the segments against the inner surface of the base and pulling them out axially, without turning the arm counter-clockwise, by reaching behind the segments behind the bumping edges delimiting the shoulders in the direction of the middle part.

With reference to the accompanying drawings, the detailed description of exemplary embodiments of the device according to the invention with the plug-in attachments of the arms in two alternative variants and the arms in different configurations follows.

The following definition applies to the entire further description. If reference numerals are included in a figure for the sake of clarity in the drawing, but are not explained in the directly associated description text, reference is made to their mention in the preceding or following description of the figures. In the interest of clarity, the repeated designation of components in other figures is mostly dispensed with, provided that it can be clearly seen in the drawing that the components are "recurring".

Figure 1

The support structure 9 is formed by a vertically standing plate 9 of a gondola typical of the shop equipment. Below the support structure 9, usually made of wood-based material, there is a platform near the floor, below which sliders or rollers, not shown, are arranged. The front side 90 and the rear side 91 are defined on the support structure 9. From the front 90, a plurality of sleeves 1 are inserted into the support structure 9 in a grid arrangement, so that only the flange 10 and the opening channel 100 are visible in each case. Several sleeves 1 are equipped with differently configured arms 5, which have pipe sections of different diameters or struts made of flat material or solid material rods. As will be described later, the arms have approaches of the first or second variant, which rest in the interior of the sleeves 1 when inserted. For higher loads, for example when two arms 5 are joined together with a cross bar 6 to form a frame 7, there are support supports 38 in front of the attachments which are not visible here and which are placed on the front side 90 when inserted. The arm type will be selected depending on the items to be attached. For light articles, for example clothing accessories, a thin arm 5 made of rod material is sufficient, while for heavier items, more massive arms 5 made of tube are used. The arms 5 can be with a few Insert the handles into the sleeves 1 or remove them again, so that the operator can quickly and individually adapt the assembly of the support structure 9 to the current requirements.

Figures 2A to 2F

A sleeve initially consists of the front flange 10, which is round here, but could also have a different cut, e.g. oval, square, rectangular or any polygon. The flange 10 has the front surface 103 and the rear surface 104, from which the tapered middle section 11 extends, which merges into the rear section 12. The front surface 103 runs around a recessed end surface 102, on which the channel 100, which is in principle rectangular in cross section, emerges with its two lateral bulges 101. On the outside of the middle section 11 there are two opposing position warts 110 and a plurality of clamping webs 111 in between. In the extension of the position warts 110, the rear section 12 each has a flattened portion 120 and is provided with an external thread 124. The flats 120 have no functional significance in the suspension device, but are advantageous on the tool side for shaping if the sleeve 1 is produced as a cast part.

The rear part 12 ends with the floor 121, in which the circular outlet 122 opens as the end of the channel 100. In front of the floor 121 there is an upward and a downward recess 123 in the rear section 12 which break through the external thread 124 on both sides and open into the channel 100. The two rectangular recesses 123 are not exactly diametrically opposed to one another, so they are not formed by a uniformly continuous opening, but are offset from one another, so that inside the sleeve 1 two shoulders 125 lie on one plane. In the direction of the flange 10, each shoulder 125 is delimited by a vertical bump edge 127 which opens outwards with the outlet 122 and is formed by the remaining wall of the rear part 12. To the rear, the two shoulders 125 are delimited by the inner surface 126 of the base 121. The channel 100 is wider in cross section than the outlet 122 in the floor 121, as a result of which the remaining inner surface 126 of the base 121 forms a stop (see FIGS. 9A and 9B). The dimension of the outlet 122 corresponds in cross section to the channel 100 and its bulges 101 on both sides, so that an arm 5 which is round in cross section can be inserted.

Figures 3A to 3D

The flange screw 2 is used to secure the sleeve 1 inserted into the supporting structure 9. In principle, the flange screw 2 consists of the large-area washer 20, the center piece 21 seated in the center thereof and the spokes 22 connecting the latter to the washer 22. In the present embodiment there are four spokes 22 each offset by 90 ° are present. With the large area of the washer 20, an adequate force distribution is intended in order to also cover a more heavily loaded sleeve 1 in a less stable material, e.g. a wooden plate, enough to support it. The washer 20 has a plurality of radially distributed screw holes 200. An internal thread 210 extends through the center piece 21 and is complementary to the external thread 124 on the sleeve 1. To grasp the center piece 21 with a tool, a polygon 211, e.g. a square is provided, to which a wrench can be attached in order to tighten or loosen the flange screw 2 screwed onto the sleeve. The screw holes 200 in the washer 20 can be used to additionally secure the flange screw 2 on the rear side 91 of the support structure 9.

Figures 4A to 4E In this group of figures, an arm 5 is shown from a round tube of larger diameter of, for example, 30.0 mm with a shoulder 3 of the first variant, the shoulder 3 with its shaft 37 being firmly inserted into the plug end 52 of the arm 5 and its head 36 protrudes axially freely from the arm 5. The approach 3 is made of flat material and preferably cut out by laser. The elongated head 36 has on its upper side the in principle horizontal ledge surface 32 which extends to the recessed cut 31 in front of which the nose 30 rises in the form of an erected hook. Above the nose 30 closes with the roof surface 35, which is above the level of the The ledge surface 32 lies. The underside 33 of the head 36 is designed as an inclined plane with an upward tendency towards the nose 30 and merges into an arc in the nose bridge 34, which is in principle vertical.

Opposite the plug end 52, the arm 5 closes with the front end 50 and has here an ordinary, upwardly projecting stop element 51, e.g. to avoid hanging hangers hanging down.

Figures 5A to 5C from two arms 5, which are made of pipe pieces of reduced diameter of e.g. 15.0 mm exist, a so-called frame 7 of U-shaped shape is formed together with a cross bar 6 connecting both arms 5, which spans a horizontal plane in the suspended state. The front ends 50 of both arms 5 are connected to the transverse rod 6, the rod ends 60 of which protrude in the example shown here beyond the connection point with the respective arm 5. When using a smaller tube diameter, the shaft 37 of the extension 3 is dimensioned correspondingly smaller in order to insert the shaft 37 into the narrower plug end 52. The contour of the head 36 remains unchanged and consequently again has the upwardly projecting nose 30, the free cut 31, the flat ledge surface 32, the sloping underside 33, the vertical nose bridge 34 and the roof surface 35. The shaft 37 is fastened in the usual way in the plug end 52, e.g. by welding, pressing or screwing.

FIGS. 6A to 6C A frame 7 is also shown in this sequence of figures, which frame is composed of two arms 5 arranged parallel to one another and a crossbar 6 connecting both arms 5. The individual arm 5 now consists of flat material. The front ends 50 of the arms 5 are preferably fixedly connected to the cross bar 6, the bar ends 60 of which also protrude here beyond the connection point to the respective arm 5. Stopper elements 61 are again located near the rod ends 60.

The arms 5 go at their plug end 52 directly into the downward Support arm 38 over and continue longitudinally, virtually without transition, in extension 3, which therefore only consists of head 36, so that a separate shaft 37 is not present here. The underside 380 of the support arm 38 merges with the plug end 52 of the arm 5, while the front edge 381 oriented towards the head 36 extends vertically downward from the attachment 3 and is provided with a plate-shaped attachment element 39 at the lower end. All contours previously described in FIGS. 4E and 5C can be found on the head 36.

Figures 7A to 7E

In this embodiment, the arm 5 consists of solid bar material with a round cross section, e.g. 8.0 mm and is provided at its plug end 52 with a shoulder 4 second variant. The approach 4 ends primarily with the chamfered end face 42, to which the end segment 41 adjoins, which in principle is a narrow cylinder section. In the direction of the plug end 52, in front of the end segment 41, there are two segments 40 projecting from the arm 5 in the shape of a wing, which lie opposite one another with a 180 ° offset and thus run on the same plane. The individual segment 40 is advantageously produced by means of a tool that deforms the bar material from two sides, so that there is a recess 43 in the form of a vertical recess above and below the segment 40, the material of which is shifted into the segment 40. The segments 40 project beyond the cross-section of the arm 5. In the inserted end position, with the stop element 51 directed upwards, the two segments 40 are in a horizontal position. The insertion and locking of the arm with the attachment 4 of the second variant are described together with FIGS. 11A to 11D.

Figures 8A to 8D

To receive the sleeve 1 in the support structure 9, a contoured opening 92, essentially a circular hole, is introduced into it, for which the CNC milling technique is particularly suitable for larger workloads. On the front side 90, the opening 92 opens out with a countersink 94 in which the flange 10 is accommodated. Usually the countersink 94 is so dimensionally kidney that the front surface 103 of the flange 10 is flush with the front 90 of the support structure 9 in one plane. In the example shown, the front surface 103 protrudes somewhat, which results in a special optical image that could be a customer request. The opening 92 is extended laterally, halfway up, with two notches 93 lying opposite one another. The notched grooves 93 preferably emerge on the rear side 91 and are dimensionally complementary to the position warts 110 on the sleeve 1, so that when inserted, the middle part 11 comes to rest in the opening 92 and the clamping webs 111 on the sleeve 1 have a solidified seat cause while the position warts 110 serve to secure rotation.

The rear part 12 of the sleeve 1 protrudes from the rear side 91 and can thus be enclosed by the flange screw 2, the washer 20 being placed on the rear side 91 and the center piece 21 having its internal thread 210 being screwed onto the external thread 124 of the sleeve 1. The polygon 211 on the center piece 21, to which a wrench can be attached, is used to tighten the flange screw 2. Locking screws could be screwed into the screw holes 200 of the washer 20, which engage in the support structure 9 and thus prevent the flange screw 2 from loosening independently.

In the inserted state, the cross section of the quasi-rectangular elongated channel 100 is vertical, the two recesses 123 point upwards and downwards, and the internal shoulders 125 lie horizontally. The channel 100 is accessible from the front 90 for fitting with an arm 5 or its shoulder 3, 4. The screwed-on center piece 21 covers the recesses 123, however, expanded cavities have arisen in the wall of the rear part 12, which are accessible from the channel 100.

FIGS. 9A to 9C. The description of the engagement of a shoulder 3, which extends from an arm 5, into the sleeve 1 follows strikes the inner surface 126 of the base 121, the front end 50 being is slightly raised compared to the horizontal. The rectangular cross section of the extension 3 on the arm 5 fills the cross section of the channel 100 in a vertical extent, the two arches 101 remaining unoccupied. In this intermediate position, the front end 50 is brought into the horizontal, so that the nose 30 moves into the recess 123 lying above and engages behind the wall in the rear part 12. The arm 5 is thus in the locked position and cannot be pulled out of the sleeve 1 without a backward movement. With increasing load on the arm 5, the ledge surface 32 on the head 36 is pressed more intensely against the upper limit in the channel 100. In principle, the head 36 is completely accommodated within the sleeve 1, so that the arm 5 extends optically to the front side 90. If you want to remove the arm 5 from the sleeve 1, the nose 30 must first be disengaged, ie withdrawn from the recess 123. Excellent angular stability is achieved due to the angular cross-sectional shape of the channel 100 and the attachment head 36 accommodated therein.

Figures IQA to 10C

On the basis of this series of figures, the hanging of a frame 7 with its two arms 5 made of flat material and a crossbar 6 spanning both arms 5 at the front ends 50 is illustrated in two sleeves 1 sitting at the same height in the support structure 9. When hanging the frame 7, the entire plane spanned by it must be angled so that the crossbar 6 is in the raised position. The introduction of the heads 36 of both lugs 3 into the respective channel 100 takes place at the same time and analogously to the previously described example, until the bridge of the nose 34 again strikes the inner surfaces 126 of the base 121. The crossbar 6 is now lowered and the lugs 30 move into the respective recess 123. In this position, both attachment elements 39 of the two arms 5 come to rest on the front side 90 of the support structure 9, thus supporting the suspended frame 7 and distributing the load acting thereon. The unhooking of the frame 7 again takes place in the reverse sequence of movements. Figures 11A to 11D

When using an arm 5 with the approach 4 second variant, the alternative function of the sleeve 1 comes into play. In order to insert the arm 5 into the sleeve 1, the arm 5 must be aligned axially to the channel 100 and with segments 40 standing vertically. This position is also visible in FIG. 11A through the transverse stop element 51. In this way, the attachment 4 is introduced into the channel 100 until the segments 40, which are still perpendicular, strike the inner surface 126 of the base 121, the end segment 41 and the final end surface 42 coming to rest in the circular outlet 122. The round cross section of the plug end 52 of the arm 5 fills the cross section of the channel 100 in the region between the two bulges 101. The cross section of channel 100 remains unoccupied at the top and bottom.

From the intermediate position, the arm 5 is rotated 90 ° clockwise so that the two segments 40 swivel into a horizontal position, hit the undercut shoulders 125 and engage behind the bumping edges 127. This state is also visible in FIG. 11C through the stop element 51, which is now vertical. The inserted arm 5 is thus held locked in the sleeve 1 and cannot be pulled out of the sleeve 1 without first being unlocked. If you want to remove the arm 5 from the sleeve 1, the segments 40 must first be brought out of engagement behind the bumping edges 127 by turning the arm 5 counterclockwise by 90 °, so that the segments 40 have lifted off the shoulders 125 and again vertically stand. In the now unlocked state, the arm 5 can be pulled axially out of the sleeve 1.
