Abstract

Holding device for a display on a shelf, in particular a goods shelf, the holding device being set up to hold the display on the shelf so that it can be moved, and the holding device having at least one carriage which can be connected to the display and is mounted so that it can be moved along a movement path.

Description

The present invention relates to a holding device for a display on a shelf, in particular a goods shelf.

In the course of progressive digitization, the spread of media content has become omnipresent in almost all areas of life. Although the possibilities for the digital visualization of physical objects and other image content have greatly improved, there is still a need to actually examine an object in question, to examine it haptically or to test its technical functionality manually. Against this background, there is a desire to familiarize a person with various objects by depositing the objects on a shelf and at the same time presenting supplementary content on a display, e.g. In principle, it would be conceivable for this to attach a display to the side of the shelf. However, the user can then effectively focus on either just the ad or just the shelf content. In addition, a display attached to the side of the shelf cannot be viewed equally well by people of different heights. This disadvantage could be reduced by positioning the display in front of the shelf. However, this would reduce the usable area of the shelf.

It is an object of the invention to create a holding device for a display on a shelf, so that the display and an interior of the shelf can be optimally kept in view at the same time and the usability of the shelf is not impaired.

The object is achieved according to a first aspect by a holding device having the features of claim 1 and in particular in that the holding device is set up to hold the display on the shelf in a displaceable manner, and wherein the holding device has at least one carriage which is connected to the display can be connected and is mounted to be displaceable along a movement path.

The fixture is generally used to mount a display on a shelf where items such as products or merchandise for sale may be displayed for inspection by interested parties. The display is preferably formed by an electrical display, for example a graphic display, in order to display image content for a person standing in front of the shelf. The image content can advantageously represent information about products or goods deposited on the shelf. The display can be formed in particular by a digital display.

The fixture allows the display to be selectively moved on the shelf. For example, the display can be held in a respective rest position by the holding device without external force being applied and can be shifted along the movement path by manual actuation. In this way, the display can be placed intuitively in an optimal position in which, on the one hand, the image content can be perceived as easily as possible, but, on the other hand, the objects positioned on the shelf can also be examined without restriction. The displaceability of the display also has the advantage that an existing interior space of the shelf can still be fully used. For example, if the display partially covers the interior space, the display need only be moved to reveal the covered interior space. The holding device thus allows the display to be positioned flexibly on a shelf without restricting its available usable area. Advantageously, the display can also be used to selectively partially cover the interior of the shelf in order to cover certain items on the shelf that are not to be shown openly.

The carriage is a moveable holding element for holding the display and can, for example, form a carrier for the display. The display can be connected to the carriage directly or indirectly, for example by a separate connecting element. The holding device can also be designed universally for holding different displays or display types. For example, displays of different sizes can be attached to one or more carriages of the holding device.

The display is not a necessary part of the holding device. Likewise, the shelf on which the holding device can be mounted is not a necessary part of the holding device. The holding device can generally be compatible with different types of shelves. It is nevertheless possible for the holding device to be adapted to a specific shelf dimensioning and/or a specific display.

When the holding device is used as intended, the display can be located at least in sections on the shelf, in particular in an interior space of the shelf.

Embodiments are disclosed in the description, the figures and the patent claims.

According to one embodiment, when the holding device is used as intended on the shelf, the movement path extends vertically or horizontally to a floor of the shelf. In this way, the mobility of the display can advantageously be adapted to a given shelf space or to a specific usage scenario. The path of movement can in particular run parallel to a side wall of the shelf. A guide device for guiding the carriage can thus be configured particularly advantageously on a side wall of the shelf.

According to a further embodiment, the holding device has a guide rail that defines the path of movement, the carriage being slidably mounted in the guide rail. For example, sections of the carriage can be accommodated in the guide rail and can be slidably mounted in the guide rail. In this way, the carriage can be guided particularly reliably, so that displays with a comparatively high mass can also be held on the shelf so that they can be displaced reliably. In addition, the guide rail can advantageously be integrated into a shelf wall. In this way, the guide rail can be fastened to the shelf with great stability and strength. Instead of the guide rail, other guide devices are also conceivable in order to keep the carriage displaceable along the movement path.

According to a further embodiment, the holding device has a rack and pinion gear for the carriage. The carriage can advantageously be coupled with further steps via the rack-and-pinion gear, as will be explained in more detail below. In addition, the carriage can advantageously be designed as a self-locking gear in order to hold the carriage in a rest position. Alternatively or additionally, the carriage is mounted in a rolling manner, for example by one or more roller arrangements, which can preferably be moved along a guideway defined by the guide rail. In this way, the slide can be mounted easily and with little wear.

According to a further embodiment, the carriage is connected to a flexible connecting element, in particular a gas pressure spring, in order to influence a movement or movability of the carriage and/or to prestress the carriage in a predetermined position. The flexible connecting element can also function as a damping means in order to be able to control a manually executed movement of the display or the carriage particularly well. The flexible connector may generally be configured to hold the display in a rest position. Here, the weight of the display is compensated so that the display does not move by itself. However, the display can be moved manually unless the display is locked with a locking means.

According to a further embodiment, the at least one carriage comprises a plurality of carriages which can each be connected to the display and are mounted so as to be displaceable along a movement path assigned to the respective carriage. When the holding device is used as intended, the movement paths of the plurality of carriages on the shelf preferably extend parallel and at a distance from one another in order to hold the display for partially covering an interior space of the shelf. For example, the guide rails may be positioned adjacent adjacent side walls of the shelf so that the display carried by the carriages advantageously extends between the side walls and forms a sliding door for the shelf interior formed between the side walls.

A first carriage of the plurality of carriages and a second carriage of the plurality of carriages can be coupled to one another with at least one coupling element for synchronization between the carriages. It is conceivable that the coupling element is part of the display, in particular is integrated into the display. However, the coupling element is preferably formed separately from the display.

According to a further embodiment, the first carriage and the second carriage are drivingly coupled to one another. In this way, displacement of one of the carriages results in driving movement of the other carriage and vice versa. Synchronous running between the carriages is hereby particularly well guaranteed. The coupling member preferably includes a belt for drivingly coupling a first rotating member of the first carriage to a second rotating member of the second carriage. The rotary elements each respond in a rotationally effective manner to a displacement movement of the relevant carriage. For example, the first rotary element rotates when the first carriage is displaced and supports a corresponding rotary movement of the second rotary element by the rotary movement of the first rotary element being transmitted to the second rotary element via the coupling element. The forced coupling between the carriages is improved in this way. In particular, a Canting of the slides is particularly reliably avoided.

According to a further embodiment, the holding device has locking means in order to optionally lock the display. The displaceability of the display can thus be selectively suppressed, in particular to prevent unwanted movement of the display. The locking means are also advantageous if the holding device is no longer able to keep the display in balance due to a fault and the display is nevertheless to be held in a predetermined position.

According to a second aspect, the object of the invention is achieved by a system comprising a shelf and a holding device in order to hold at least one display on the shelf in a displaceable manner. The holding device is preferably designed according to at least one of the described embodiments. The holding device is also attached to at least one wall of the shelf with one or more guide rails and/or embedded at least in sections in the at least one wall of the shelf. In this way, the holding device can be attached to the shelf in a particularly stable manner. In addition, a particularly low-vibration movement of the display on the shelf can be guaranteed.

According to one embodiment, the holding device comprises a plurality of carriages which can each be connected to the display and are each mounted displaceably in one of the plurality of guide rails. The display preferably extends between the guide rails and at least partially covers an interior space of the shelf as a function of a displacement position of the carriages. As a result, the display is held particularly stably on the shelf, and a risk of injury from protruding edges of the display can also be completely avoided.

According to a third aspect, the object of the invention is achieved by a system comprising a drive unit for an electrical display and at least one holding device to hold the display on a shelf in a displaceable manner. The holding device is preferably designed according to at least one of the described embodiments. The drive unit is set up to drive the electrical display to display image data when the display is held displaceably by the holding device on the shelf when the holding device is used as intended. In this way, the display of the image data can be made dependent on a usage situation of the shelf and the display. For example, the image data can take place depending on a position of a person in front of the shelf, a position of the display relative to the person and/or the shelf, or the presence of one or more people in front of the shelf.

According to one embodiment, the system also includes a position sensor, in particular for determining a position of the display relative to a reference position, the drive unit also being set up to drive the electrical display for displaying the image data depending on the position of the display. For example, an image displayed on the display can be defined as stationary, so that the image moves out of the display from the point of view of the viewing person when the display moves. The person can hereby be animated to move the display to a predetermined position in which the image can be fully perceived. The predetermined position can be defined in such a way that products deposited on the shelf, which are associated with the displayed image, can be viewed particularly well in the predetermined position of the display on the shelf or can be picked up. In addition, it is possible to display different images on the display, with each of the different images being assigned a predetermined position in which the relevant image is displayed on the display.

According to a further embodiment, the reference position is defined with reference to a further electrical display which is preferably pivotably and/or fixedly attached to the shelf. In particular, the additional display can be fixed in place on the shelf, at least in sections, in that the display can be pivoted about a stationary pivot axis. The further electrical display can be arranged adjacent to an upper edge of the shelf, with the slidable display being below the further display and being movable relative to the further display. In the event that the further display is designed to be pivotable, the further display is preferably in a closed position when the moveable display is used as intended, in which the further display covers an interior space of the shelf and defines the reference position. The additional display can advantageously be used to display additional information to supplement the scrollable display.

The displays mentioned can form respective components of the system, in particular if the displays are adapted to the holding device.

It goes without saying that features that are disclosed in connection with the holding device described can also be implemented in the systems described. Conversely, individual features that are described in connection with the systems can also be implemented in the holding device.

The size of the display can be adapted to a shelf size. For example, the width of the display can be adapted to an inside width of the shelf, so that the display can be movably held by the holding device between two side walls of the shelf.

Identical and corresponding parts are marked with the same reference numbers.

A holding device 10 is in 1 shown in a perspective view obliquely from above. The holding device 10 has two lateral guide rails 12 and 12', which are arranged spaced apart from one another in parallel in order to hold an electrical display 14 between the guide rails 12 and 12' so that it can be displaced along a displacement direction R. In 1 the displacement direction R runs vertically to a floor extending perpendicularly to the guide rails 12 and 12', so that the holding device 10 with the guide rails 12 and 12' defines a vertical movement path for the display 14.

The display 14 has a bottom handle bar 20 that can be manipulated by a person to selectively slide the display 14 along the translation direction R (not shown). The holding device 10 is adapted to hold the display 14 in a respective rest position, ie in balance, without the action of manually exerted displacement forces. Optionally, the holding device 10 can be configured to move the display 14 into the in 1 move position shown. The technical means of realizing these holding properties are discussed below with particular reference to 15 and 16 explained further.

In 1 Also shown is a second display 16 which is connected to two brackets 18 extending perpendicularly rearwardly from the display 16 for sectionally mounting the display 16 in place on a shelf, particularly adjacent an upper side of the shelf, cf. 2 until 4 . The display 16 can be pivoted about a stationary axis of rotation in order to be able to use the interior space of the shelf located behind the display 16 . The display 16 can thus be selected from the in 1 until 3 shown position only to be unfolded to release the hidden from the display 16 shelf interior.

2 shows a front view of a shelf 22 on which the holding device 10 of 1 mon animal. The shelf 22 has side walls 24 and 24', with the guide rail 12' embedded in the side wall 24' and the guide rail 12 embedded in the side wall 24, so that the guide rails 12 and 12' are embedded in the front view of FIG 2 are not visible. Furthermore, the shelf 22 has a plurality of shelves 26 which extend perpendicularly between the side walls 24 and 24 ′ and delimit a plurality of interior spaces 30 formed between the shelves 26 . The interior spaces 30 are used to accommodate objects, not shown, which can be inspected by a person in front of the shelf 22 . It is understood that the shelf 22 may include additional side walls and shelves to form a shelf wall (not shown).

In 3 is the shelf 22 of 2 shown in a partial perspective view obliquely from below, only one lateral half of the shelf 22 being shown. Out of 3 it can be seen that the guide rail 12' is embedded in the side wall 24'. The guide rail 12 is embedded in the side wall 24 in a corresponding manner (not shown). In addition, it can be seen that the shelf 22 has further shelves 26 ′, which delimit further inner spaces 30 ′, which are covered by the display 14 . The interior space 30 formed between the immediately adjacent shelves 26 and 26' is only partially covered by the display 14. By moving the display 14 in a direction away from the display 16, the interior spaces 30′ covered by the display 14 can be selectively released so that they are accessible from the outside and in particular products deposited there can be freely viewed and removed as required.

Out of 3 It can also be seen that the shelf 22 has two transverse walls 28 which extend behind the display 16 perpendicular to the side walls 24 and 24'.

In 4 is the shelf 22 of 3 shown in a side view, from which it can be seen in particular that the display 16 is suspended with the supports 18 on the upper transverse wall 28 of the shelf 22. In contrast to the display 14, the display 16 cannot be moved.

In 5 the shelf 22 is shown in a rear view corresponding to that in 2 opposite front shown. It can be seen that the display 14 is mounted on a slide 32 or 32' in the region of two opposite side sections, with the slides 32 and 32' jointly holding the display 14 on the shelf 22 in a displaceable manner. The carriages 32 and 32' are each slidably mounted in the associated guide rails 12 and 12', as will be described further below.

Provided between the carriages 32 and 32' is a transverse housing 34, in the interior of which a drive belt 36 is arranged in order to drivingly couple the carriages 32 and 32' to one another. The drive belt 36 is particularly in 6 to see where the fixture 10 is shown without the shelf 22. Furthermore, in 6 the transverse housing 34 is shown without a back cover plate so that the drive belt 36 can be seen. How also from 6 As can be seen, the carriage 32 is movably mounted on the guide rail 12 and the carriage 32' on the guide rail 12', with the carriages 32 and 32' each being movable along the displacement direction R, ie parallel to the guide rails 12 and 12'. In this way, each guide rail 12 and 12' defines a movement path for the associated carriage 32 or 32'.

7 shows the holding device 22 of FIG 5 , wherein a rear housing plate of the display 16, a rear housing plate of the transverse housing 34 and a rear housing plate of the carriages 32 and 32' are not shown. In detail 64 it can be seen that the carriage 32 has a rotatably mounted gear wheel 42 . It can also be seen in detail 62 that the carriage 32 ′ has a rotatably mounted gear wheel 38 which in turn is rotationally coupled to a rotatably mounted gear wheel 40 . The drive belt 36 is rotationally coupled to the gears 40 and 42 . The operation of the carriages 32 and 32' and the gears 38, 40 and 42 will be described in more detail below with reference to FIG 15 and 16 explained.

In 15a the carriage 32' is shown together with further elements of the holding device 10, which are accommodated in the guide rail 12' when the holding device 10 is used as intended ( 15b) . The carriage 32' is coupled to a gas spring 48 which includes a piston 50 and an associated cylinder 52. As shown in FIG. The piston 50 has a first end fixedly connected to the carriage 32' and a second end slidably mounted in the cylinder 52, the cylinder 52 being stationarily mounted in the guide rail 12'. The gas pressure spring 48 serves as a damping means in order to dampen a movement of the carriage 32' and to compensate for the weight of the display. The movement of the display 14 can thus be maintained in a respective rest position and more easily controlled by a person. Optionally, the gas spring 48 can be configured to bias the carriage 32' to a predetermined position, such as the position shown in FIG 7 position shown in which display 14 is positioned adjacent to display 16.

The carriage 32' is also coupled via the gear wheel 38 to a toothed rack 44', which is mounted stationarily in the guide rail 12'. If the carriage 32' is displaced along the displacement direction R, the toothed wheel 38 is forced into rotation by mechanical interaction with the stationary toothed rack 44'. At the same time, the gear wheel 40 is rotated in the opposite direction in order to drive the drive belt 36 . The drive belt 36 is stretched over a gear wheel 46 which is coaxially fixed to the gear wheel 40 (cf. 8th ). The drive belt is a toothed belt, so that the drive belt cannot slip.

The carriage has a plurality of hooks 60 which engage associated apertures in the display 14 to releasably connect the display 14 to the carriage 32' (see Figs. 7 ). The display 14 can thus be hooked into the hooks 60 in order to reliably connect the display 14 to the carriage 32. Additional fastening material is not required. In principle, however, other fastening means are also conceivable in order to connect the display 14 to the carriage 32'.

In 15c are the carriage 32' and the guide rail 12' of FIG 15b presented in a transparent view on a front side.

16a and 16b show the carriage 32' together with the gas pressure spring 48 and the toothed rack 44', each in a further perspective view in order to clarify further advantageous details of the holding device 10. It can be seen that the carriage 32' has a plurality of roller arrangements 54, 56 and 58 with a plurality of individual rollers which are mounted in a rolling manner on associated guideways within the guide rail 12', cf. 15c . The carriage 32' can thus be moved along the displacement direction R in a particularly light and low-wear manner.

It goes without saying that the carriage 32, with the exception of the gear wheel 40, is designed in the same way as the carriage 32' and is movably mounted in the guide rail 12 via a gas pressure spring, a rack and pinion gear (rack 44 and gear wheel 42) and roller arrangements, cf. 7 and 9a .

The functioning of the drive belt 36 is described with reference to FIG 7 until 9 explained further. The carriage 32' is displaced along the displacement direction R by a movement of the display 14, so that the gear wheel 38 is driven in a first direction of rotation. The gear wheel 40 is thereby driven in a second direction of rotation, which is opposite to the first direction of rotation. The rotational movement of the gear wheel 40 is transmitted via the drive belt 36 to the gear wheel 42 of the carriage 32 in order to drive the gear wheel 42 in the second direction of rotation. In this way, the gearwheel 42 is driven in a rotational movement that runs in the opposite direction to the gearwheel 38, but has a corresponding rotational movement when the carriages 32 and 32' are moved by a distance by displacing the display 14. However, tilting of the carriages 32 and 32' is reliably avoided in this case. In other words, smooth synchronization between the carriages 32 and 32' is ensured. A slight shifting of the display 14 is thus also ensured in particular when the display 14 is operated by a person not in the center but laterally, for example in the area of one of the carriages 32 or 32', in order to shift the display 14. The display 14 can thus be moved fluently and without tilting even with a one-sided driving force load.

The section 62 of 7 is in 8th enlarged and shows in particular the gear wheel 38 coupled to the toothed rack 44' and the gear wheel 40 coupled to the drive belt 36. As explained, the gear wheel 40 serves to provide a rotational movement in the opposite direction to the gear wheel 38, so that the drive belt 36 drives the carriage 32 via the Gear 42 drives synchronously with the gear 38 of the carriage 32'. It goes without saying that the explained transmission of the driving force is also effective in the opposite direction, ie from the carriage 32 to the carriage 32'.

The section 64 of 7 is in 9a shown in an enlarged view and illustrates the coupling of the gear 42 with the toothed rack 44, which is stationarily mounted in the guide rail 12. The gear wheel 42 is rotatably mounted about an axis of rotation A extending perpendicularly to the plane of the paper. The gears 38 and 40 of the carriage 32' are mounted in a corresponding manner so as to be rotatable about axes of rotation of the carriage 32'.

In 9a a manually adjustable locking element 45 is also shown in order to be able to selectively fix the carriage 32 and thus also the display 14 connected to the carriage 32 in a predetermined position. An unintentional or undesired displacement of the display 14 can be effectively prevented in this way.

In 7 a section 66 is also marked, which in 9b is shown in an enlargement. The section 66 shows an incremental encoder 68 which is attached to a lower edge of the display 16 and is set up to determine the distance between the display 14 and the display 16 . The incremental encoder is preferably designed as an optical incremental encoder, which uses laser pulses to determine the distance from the Runtime determined until receipt of the reflected laser pulse. In principle, however, other sensor technologies can also be used to determine the distance or, in general, the position of the display 14 .

The incremental encoder 68 is connected to a drive unit (not shown) in order to display predetermined image data on the display 14 as a function of the position of the display 14 . The image data can in particular be a still image, for example a logo for easier identification of products deposited on the shelf 22 .

It is understood that display 14 and display 16 may each be connected to an electrical supply to operate displays 14 and 16, respectively, to display image data (not shown). For this purpose, the displaceable display 14 can be connected to a flexible cable which is connected to the back of the display 14 . Alternatively, the display 14 can be powered via one or more wiper contacts provided on the carriage 32 or 32'. It is also conceivable that one of the roller arrangements of the carriage 32 or 32' is designed as a current collector, so that a supply voltage applied to a guide rail of the roller arrangement can be reliably tapped off in any displacement position in order to supply the display 14 with electricity (not shown).

With reference to the 10 until 14 a holding device 70 is described below, which deviates from the holding device 10 of 1 is designed to hold an electrical display 72 slidably in a horizontal sliding direction R. The holding device 70 has a guide rail 76 which defines a horizontal movement path for the display 72 . The holding device 70 can, for example, as in 11 shown, be mounted on a shelf element 74 extending horizontally to a floor, the guide rail 76 resting parallel to the shelf element 74 on an upper side of the shelf element 74 and being fixedly connected to the shelf element 74 . The display 72 is equipped laterally with two opposite handles 78 which can be actuated by a person (not shown) in order to be able to move the display 72 along the displacement direction R.

How eg from 10 and 12 As can be seen, the holding device 70 has a carriage 84 which forms a carrier for the display 72 . The carriage 84 is mounted to roll on the guide rail 76 at one end and is fixedly connected to the display 72 at an opposite end. Extending between the display 72 and the carriage 84 is a bezel 80 which is connected to the shelf member 74 (see also FIG 11 ).

A supply module 82 is arranged on the shelf element 74 in order to supply the display 72 with electrical energy. In addition, the supply module 82 serves to control the display 72 with predetermined image data. The actuation can take place in particular as a function of data from a position transmitter (not shown), which determines the position of the display 72 along the displacement direction R relative to a reference position.

The supply module 82 is electrically connected to the display 72 via terminals 98 and a cable 94 . In the region of the guide rail 76, the cable 94 is accommodated in a rolling trailing line 86, one end of which is flexibly connected to the carriage 84.

In 13 the shelf element 74 is shown together with the mounted holding device 70 and the display 72 in a perspective view obliquely from above. The section 88 is shown enlarged separately and shows part of the supply module 82 and an electrical plug connector 90 which can be connected to the supply module 82 in order to electrically connect the supply module 82 to a supply source. Another clipping 92 from 13 is in 14a shown in an enlarged view and illustrates parts of the trailing line 86 and a transition of the cable 94 from the guide rail 96 to the carriage 84. Another section 96 of 13 is in 14b shown in an enlarged view and illustrates the course of the electrical connection from the supply module 82 via the terminals 98 and the cable 94 into the guide rail 76 .

Underneath the shelf element 74, when the holding device 70 is used as intended, a plurality of shelves are arranged on a shelf between the respective side walls of the shelf (not shown). The interior spaces of the shelves formed between the shelves and side walls can be partially covered by the display 72 . However, the display 72 can optionally be moved along the displacement direction R in order to bring the display 72 into an optimal viewing position and at the same time free up adjacent interior spaces of the shelf in order to appraise products deposited on the shelf.
