EP3528235B1 - Adapter device and method for fixing an information carrier to a supporting rail provided with two holding devices - Google Patents

Description

I. Field of application

The present invention relates to an adapter device and a method for attaching an information carrier to a carrier rail provided with two holding devices. The adapter device is used in particular on shelves or other goods presentation devices of retail stores that have the support rail. The information carrier can be labels made of sufficiently rigid material, such as cardboard or plastic, with printed price and / or product information, or electronic labels with a display that shows price and / or product information. Electronic labels are known as ESL price boards (ESL = Electronic Shelf Labeling).

II. Technical background

From the DE 39 00 904 C1 a label strip for attaching to a price rail is known. The label strip has a pocket for receiving a label, which is formed by a rear wall strip and a transparent cover strip. A short and a long insert leg are attached to the back of the rear panel strip. The long plug-in leg is articulated to the rear wall strip of the label strip.

The price rail has two groove-like holding devices. To fasten the label strip to the price rail, the free ends of the insertion legs are each inserted into one of the groove-like holding devices. Then the label strip is pressed against the price rail, whereby the long insert leg is pushed into the in Fig. 2 the DE 39 00 904 C1 position shown is pivoted, in which it runs essentially parallel to the rear wall strip or the cover strip.

To secure the label strip on the price rail, a latching body attached to the rear wall strip engages in a latching cavity located on the long plug-in leg and thus securely holds the free ends of the plug-in legs in the groove-like holding devices on the price rail. The label can be inserted into the pocket of the label bar before or after the label bar is mounted on the price rail.

The known label strip has the disadvantage that the latching connection between the rear wall strip and the long insertion leg can wear out, so that a secure hold of the label strip on the price rail is no longer guaranteed. In addition, the construction of the known label strip is relatively complex, so that its mass production is associated with comparatively high manufacturing costs.

From the DE 195 01 972 A1 a device for fastening information carriers in the form of a price display unit 19 or a paper 20 is known. In this device, the information carrier is accommodated in an element 6 which can be fastened to a carrier profile 1 with the aid of two limbs that are articulated to one another.

From the FR 2 992 764 A1 a device for fastening to the edge of a shelf is known, in which an information carrier in the form of a label is accommodated in a label holder 11. The label holder 11 is fastened to a support rail 2 with the aid of two limbs that are articulated to one another.

III. Presentation of the invention a) Technical task

It is therefore the object of the present invention to provide an adapter device and a method for attaching an information carrier, in particular a printed label, an electronic label or a monitor, to a carrier rail provided with two holding devices, which or which also after multiple mounting and dismantling the adapter device on and from the support rail ensures a secure hold of the adapter device on the support rail and at the same time is associated with the lowest possible manufacturing costs.

b) Solution of the task

This object is achieved with an adapter device or with a method having the features of claims 1 and 15, respectively. Further refinements of the present invention emerge from the subclaims.

According to the invention, an adapter device is proposed for attaching an information carrier, in particular a printed label, an electronic label or a monitor, to a carrier rail provided with two holding devices, the carrier rail being, for example, on a shelf, on another product presentation device, on a wall or in a hanging rail Shape located on a ceiling of a retail store. The adapter device has a first leg and a second leg, each of which can be releasably held on one of the two holding devices of the support rail. The two legs are preferably designed as a flat body, the thickness dimension of which is significantly smaller than its dimensions in the other two spatial directions.

The first leg and the second leg of the adapter device are preferably directly connected to one another via a hinge, a first connecting device for connecting the information carrier to the first leg being attached to the first leg and a second connecting device to the second leg for connecting the information carrier to the second leg is attached. Accordingly, when the adapter device is in an assembled state, in which the information carrier is not connected to the adapter device, the first and second legs are freely pivotable about the joint and form an angle of less than 180 ° to one another. In a blocked state of the adapter device in which the information carrier can be connected to the adapter device via the first and the second connection device, the joint can be blocked by the information carrier itself.

In the blocked state, the legs of the adapter device form an angle of essentially 180 ° and thus lie essentially in a plane spanned by them. The information carrier, for example a printed or electronic label, has such a flexural rigidity that is sufficient to keep the legs blocked in the blocked state. The information carrier thus acts like a mechanical blocking bolt which, due to its connection to both the first leg and the second leg, holds both legs in a stretched or flat state.

Since the information carrier itself can act as a mechanical blocking bolt in the adapter device according to the invention, it is not necessary to provide additional mechanical locking or safety devices on the adapter device itself, which wear out after repeated use and thereby their locking or Could lose the security effect. The task of ensuring that the adapter device is securely held on the carrier rail is rather shifted to the information carrier itself. This is subject to very little wear, if at all, even with multiple assembly and disassembly of the adapter device on or from the support rail.

Moreover, the lack of need for additional mechanical locking or safety devices on the adapter device itself advantageously means that the construction of the adapter device according to the invention can be kept comparatively simple and thus inexpensive to manufacture. If plastic is selected as the material for the adapter device, then, for example, inexpensive manufacture by way of the injection molding process, in which, due to the simple construction of the adapter device according to the invention, only correspondingly simple injection molds have to be provided.

In the case of the adapter device, the first connecting device and the second connecting device are preferably of identical design. Alternatively, it is conceivable, for example, depending on the construction of the rear side of the information carrier, to design the first connection device in terms of its type and mode of operation differently from the second connection device.

The connection of the information carrier to the first limb and the second limb of the adapter device can take place in various ways within the scope of the present invention. On the one hand, it is conceivable to use the first connecting device and / or the second connecting device to establish a latching connection between the information carrier and the first leg or the second leg of the adapter device. On the other hand, there is the possibility of establishing a sliding connection between the information carrier and the first leg or the second leg of the adapter device by means of the first connecting device and / or the second connecting device. Finally, it is also conceivable to provide a combined sliding and locking connection between the information carrier and the first leg or the second leg of the adapter device. The last-mentioned combined variant offers the user of the adapter device the greatest possible freedom of handling when it comes to attaching the information carrier to the adapter device depending on the spatial environmental conditions in which the carrier rail is located.

A latching connection can be designed, for example, in such a way that the first connecting device and / or the second connecting device has at least two latching fingers with latching lugs, between which the information carrier can be latched from the front. A sliding connection can be designed, for example, in such a way that the first connecting device and / or the second connecting device has at least two guide fingers with guide lugs, between which the information carrier can preferably be inserted from above. With the combined latching and sliding connection, it is particularly advantageous if the guide fingers with the guide lugs simultaneously form the latching fingers with the latching lugs.

In order to prevent the information carrier attached to the adapter device from wobbling, at least one flat spring can each be formed in or on the first leg and in or on the second leg. The at least one flat spring presses the information carrier without play against the latching lugs and / or guide lugs holding it. The flat spring is in each case preferably formed by a curved material web made of the material of the first leg or the second leg. The flat spring can advantageously be arranged between the locking fingers and / or between the guide fingers.

The second leg can advantageously have a stop projection as a stop for the information carrier. This stop enables a uniform positioning of all information carriers carried by the one carrier rail, particularly when there are several adapter devices on a carrier rail. In the case of a horizontally extending support rail, the second leg forms the lower leg of the adapter device and the stop then forms a height stop for the information carrier.

In the case of information carriers that are relatively large when viewed from above, the first leg and / or the second leg can have a spacer projection which serves as a positioning aid to position the information carrier in the blocked state essentially parallel to the plane spanned by the first and second legs .

The first leg and / or the second leg each have a retaining edge at its free end facing away from the joint, which edge can engage positively in the respective retaining device on the support rail. This retaining edge is on the first leg and / or designed to be flattened in the case of the second leg in order to facilitate the introduction into the holding devices of the carrier rail, which are designed as holding grooves, for example.

The joint connecting the first leg to the second leg only needs to have one degree of freedom and can be of any type. A film hinge that can be used in particular when the adapter device according to the invention is made from plastic has proven to be advantageous and inexpensive.

According to the invention, a method for attaching an information carrier, for example a printed or an electronic label, to a carrier rail provided with two holding devices is proposed, in which an adapter device according to the invention is used. As a first step, the method comprises pivoting the first leg relative to the second leg about the joint, so that a kinked adapter device is obtained in which the two legs form an angle of less than 180 ° to one another. In the bent adapter device, the joint is bent in such a way that the holding edges of the first leg and the second leg facing away from the joint occupy a spatial distance from one another which is less than a predetermined distance that the two holding devices of the carrier rail have from one another. This enables the second step of the method according to the invention, according to which the bent adapter device is introduced into the carrier rail with its retaining edges in a form-fitting manner.

As part of a third step of the method according to the invention, the first leg is pivoted around the joint relative to the second leg, so that an elongated adapter device is obtained in the carrier rail, in which the joint is elongated and is located between the first leg and the second leg sets an angle of substantially 180 °.

As part of the fourth and last step of the method according to the invention, the information carrier is connected both to the first connecting device of the first leg and to the second connecting device of the second leg. As a result, the joint of the stretched adapter device is blocked by the information carrier itself and the retaining edges of the first leg and the second leg are held in a retaining connection with the two retaining devices of the carrier rail.

The same reference symbols are used below for the same parts or elements. If the same reference symbols are used in connection with the two different exemplary embodiments, the parts or elements identified with the same reference symbols correspond to one another in functional terms.

Fig. 1 shows a perspective view of a first embodiment of the adapter device according to the invention. The adapter device 1 has a first leg 6 and a second leg 7, which are directly connected to one another via a joint 8 in the form of a film hinge. The legs 6 and 7 are designed as rectangular flat bodies, as in the Figs. 1-5 can be seen. The entire adapter device 1 according to the first exemplary embodiment is made in one piece from a plastic.

As best in Fig. 1 as in Fig. 6 can be seen, which is an enlarged sectional view according to section AA in Fig. 3 shows, two spaced guide fingers 9 protrude from the leg 6 to the front. The two guide fingers 9 each have a guide nose 11 at their free ends. In a structurally identical manner, two spaced guide fingers 10 protrude from the leg 7 and each have a guide nose 12 at their free ends.

The guide fingers 9 and the guide lugs 11 form a first connecting device, with the help of which a into the Figures 7-10 as well as the Fig. 13 and 14th The information carrier 2 shown can be connected to the first leg 6 in the form of an electronic label. In the same way, the guide fingers 10 and the guide lugs 12 form a second connecting device, with the aid of which the aforementioned information carrier 2 can be connected to the second leg 7.

In the Figures 7-10 an electronic label 2 is shown as an information carrier which, with the aid of the adapter device 1, is attached to a Figures 11-14 partially shown support rail 3 is to be attached. The carrier rail 3 is located, for example, on shelves or other goods presentation devices in retail stores such as supermarkets. The electronic label 2 has a display device 19, for example in the form of an LCD display or in the form of electronic paper (passive, non-luminous displays that simulate the appearance of ink or color on paper) on which product and / or Price information about the goods can be displayed which are spatially assigned to the arrangement position provided for the label 2 on the shelf or in the other goods presentation device.

As in the Figures 8-10 As can be seen, the electronic label 2 has an electronics unit 20 on its rear side 24, in which all hardware and software components required for the operation of the electronic label 2 can be located, which are in the Figures 8-10 are not shown and which include, for example, a battery, a data memory for storing the product and / or price information to be displayed, and a processor. How best Fig. 10 can be seen, the electronics unit 20 has along its in Fig. 8 left and right side edge guide projections 21 which form guide recesses 22 between them and the rear side 24 of the electronic label 2. Depending on the design of the label 2 used, the guide projections 21 and guide recesses 22 can of course also be designed completely independently of the presence of an electronics unit 20 protruding from the rear side 24. The main thing is that the guide projections 21 and guide recesses 22 can interact to produce a connection with the guide fingers 9 and 10 and the guide lugs 11 and 12.

In the in Fig. 1 shown blocked state, in which the legs 6 and 7 lie in one plane or form an angle of 180 ° between them, the electronic label 2 with its electronics unit 20 in Fig. 1 from above in such a way between the guide fingers 9 and the Guide fingers 10 are pushed so that, on the one hand, the guide lugs 11 and, on the other hand, the guide lugs 12 engage in the guide recesses 22 located on the electronic label 2. There is thus a sliding connection between the electronic label 2 and the leg 6 and leg 7 of the adapter device 1. So that the label 2 in Fig. 1 does not fall down from the guide fingers 9 and 10, a forwardly projecting stop projection 14 is arranged on the leg 7, against which the in the Fig. 8 and 9 to be recognized lower end of the electronic unit 20 can strike. The stop projection 14 accordingly acts as a height stop in the exemplary embodiment shown.

Instead of the sliding connection between the electronic label 2 and the adapter device 1 provided in the first exemplary embodiment, a latching connection between the electronic label 2 and the adapter device 1 can alternatively be provided. For example, for this purpose the guide fingers 9 and 10 could be designed with such inherent elasticity that the electronic label 2 with its electronics unit 20 is in the Fig. 1 and 3 from the front or in Fig. 6 can be pressed from above against the leg 6 and the leg 7 in order to effect the connection with the adapter device 1. Such an assembly variant from a direction perpendicular to the plane spanned by the legs 6 and 7 could be advantageous if the mechanical ambient conditions in which the carrier rail 3 is located, an insertion of the label 2 in Fig. 1 not allowed from above. In this context, it would be particularly advantageous to design the guide fingers 9 and 10 and the guide lugs 11 and 12 both as guide elements and as latching elements. This would ensure the greatest possible flexibility with regard to the mounting direction of the electronic label 2.

In order to ensure that the electronic label 2 sits on the adapter device 1 with as little wobble as possible, the first exemplary embodiment has a flat spring 13 between the two guide fingers 9 and the two guide fingers 10. As best in the Figure. 1 and 2 can be seen, the flat spring 13 is from an in Fig. 1 formed out of the plane of the leg 6 or 7 forwards curved material web, which is delimited on the left and right by a passage slot 23 from the remaining material of the leg 6 or 7 (cf. Fig. 6 ). At your in Fig. 1 and 2 At the upper and lower end, the flat spring 13 is integrally connected to the remaining material of the leg 6 and 7, respectively.

If the electronic label 2 with its electronic unit 20 in Fig. 1 pushed from above between the guide figures 9 and 10, the two flat springs 13 press the electronics unit 20 into the Fig. 1 and 3 forward or in Fig. 6 up. The in Fig. 10 The guide projections 21 shown are pressed against the guide lugs 11 and 12, so that the electronics unit 20 is guided without play in the direction perpendicular to the plane spanned by the legs 6 and 7.

As in the Fig. 1 , 3 and 5 can be seen, the first leg 6 has a Fig. 1 and 3 forward as well as in Figure 5 to the right of it protruding spacer projection 15, which is designed in the embodiment shown in the form of a rectangular, closed circumferential web of material. A corresponding identically designed spacer projection 16 is attached to the leg 7. The spacer projections 15 and 16 serve as a positioning aid which, when the electronic label 2 is attached to the adapter device 1, is in contact with the in the Figures 8-10 to be seen back 24 of the electronic label 2 come to the label 2 as parallel as possible to that in the Fig. 1 and 3 from the legs 6 and 7 to keep the spanned plane. In this way, it is prevented that the label 2, when attached to the adapter device 1, rotates about a vertical axis running between the guide fingers 9 or the guide fingers 10 in the direction of the adapter device 1.

According to the Fig. 1 , 3 , 4 and 5 If the leg 6 has a retaining edge 17 at its end facing away from the joint 8, which in the exemplary embodiment shown is flattened (cf. Figures 4 and 5 ). In the same way, the leg 7 has, at its end facing away from the joint 8, a holding edge 18 which, in the exemplary embodiment shown, is flattened in the same way as the holding edge 17 of the leg 6.

The Figures 11-14 illustrate the process of mounting the adapter device 1 on the carrier rail 3 and the electronic label 2 on the adapter device 1. The carrier rail 3, which is designed as a profile rail, for example, from aluminum, points into the Figures 11-14 above and below a holding device 4 and 5, respectively, in the form of a holding groove, which cannot be seen, for receiving the holding edges 17 and 18 of the adapter device 1.

Corresponding Fig. 11 the adapter device 1 is first brought into its assembly state in which the legs 6 and 7 are bent relative to one another, ie at an angle of less than 180 ° with each other. The kink angle between the legs 6 and 7 is to be selected so that the retaining edges 17 and 18 of the adapter device 1 can be inserted positively into the retaining devices 4 and 5 of the support rail. As in Fig. 12 As shown, the adapter device 1 is then brought into its stretched blocking state, in which the legs 6 and 7 span a common plane and form an angle of substantially 180 ° to one another. Both retaining edges 17 and 18 are then located in the groove-shaped retaining devices 4 and 5 of the support rail 3 and are shown in FIG Fig. 12 therefore no longer visible.

As in Fig. 13 is then shown the electronic label 2 with its in the Figures 8-10 The electronic unit 20 shown is pushed from above between the guide fingers 9 and 10 until it rests against the stop projection 14. This state is in Fig. 14 shown. In Fig. 14 It is also easy to see that the electronic label 2 in its top view is approximately as large as the adapter device 1 itself, so that the latter is hardly noticeable when the label 2 is mounted.

Fig. 15 shows a second embodiment of the adapter device 1 according to the invention in front of the carrier rail 3 with its groove-like holding devices 4 and 5. In contrast to the first embodiment, the legs 6 and 7 are each L-shaped here. The retaining edges 17 and 18 are each located on the shorter L-leg. The hinge 8 is not a film hinge, as in the first exemplary embodiment, but a hinge similar to a piano hinge. In the second exemplary embodiment, the first leg 6 has a total of six guide lugs 11. In the same way, the second leg 7 is provided with a total of six guide lugs 12. In contrast to the first embodiment, elongated guide walls acting in the sense of guide fingers 9 and 10 are formed here, which are significantly longer than guide fingers 9 and 10 and extend over the entire length of the respective long L-leg of leg 6 and 7, respectively.

The basic procedure for assembling the in Fig. 15 The adapter device 1 shown on the carrier rail 3 and the electronic label 2 on the adapter device 1 is the same as was described in connection with the first exemplary embodiment.

    • pivoting the first leg (6) relative to the second leg (7) about the joint (8), to obtain a stretched adapter device (1) in the support rail (3), in which the joint (8) is stretched and an angle of essentially 180° is formed between the first leg (6) and the second leg (7), and

    • connecting the information carrier (2) to both the first connection means (9) of the first leg (6) as well as to the second connection means (10) of the second leg (7) in such a way that as a result the joint (8) of the stretched adapter device (1) is blocked, and the retaining edges (17, 18) of the first leg (6) and of the second leg (7) are held in a retaining connection with the two retaining means (4, 5) of the support rail (3).
