Definitions

• the present invention relates to a system for fixing accessories, such as shelf dividers, feed devices, holders for information carriers, etc. to a shelf, to which shelf a number of accessories can be fixed detachably in various positions along the length of the shelf.
• the system comprises at least one accessory having a foot and a clamping device, which latter comprises a channel element extending parallel with the longitudinal direction of the shelf and having an open longitudinal side for forming an open channel, an actuable holding member, extending along the channel element, for holding at least one foot in the channel, and a control member for transferring the holding member between a holding position, in which the foot is held in a fixation position in the channel, and a release position, in which the foot is freed.
• the invention also relates to a clamping device and an accessory for such a system, a shelf comprising such a system and a shelf comprising such a clamping device.
• shelf dividers In general stores, for example, goods are often displayed on shelves.
• accessories such as shelf dividers, various types of feed devices, holders for flags and other information carriers, various types of goods trays, etc.
• Such accessories are often fastened to the shelves.
• the invention is related to the fixing of such accessories to shelves.
• the invention is described below with respect to the fixing of shelf dividers to shelves. That which is herein stated about shelf dividers shall also apply to other types of accessories, such as the aforementioned.
• Shelf dividers are used, for example, in general stores, in which goods are stored and displayed on shelves.
• the principal function of the dividers is to separate different categories of goods and create order on the shelves.
• the shelf dividers are often constituted by partitions which are fastened to the shelf plane so that they extend at right angles to the longitudinal direction of the shelf and jut up perpendicularly from the shelf plane.
• the shelf dividers can be fastened to the shelf in a variety of ways, for example mechanically with screws or the like, by frictional engagement or by adhesion with double-sided adhesive tape or the like.
• the arrangements which are used to fasten the shelf dividers should have some basic characteristics .
• One important characteristic is that it should be possible to fasten the shelf dividers in arbitrary positions along the length of the shelf, so that the bays delimited by the dividers can be made any chosen width so as to fit different packagings and quantities of goods.
• the dividers should be firmly secured to the shelf in order to prevent them from being mistakenly detached or displaced from their intended positions.
• a goods feeding device is placed between two shelf dividers, it is important for the shelf dividers not to be moved even marginally closer together, since the friction between the goods and the shelf dividers can then be such that the feed does not work.
• the holding should also ensure that the dividers are steady, so that they do not tilt.
• shelf dividers When shelf- dividers are installed on an empty shelf, the shelf dividers are normally placed first in estimated approximate positions along the shelf, with regard to the goods to be placed on the shelf.
• the person carrying out the installation usually starts at one end of the shelf and works further along the shelf toward the other end. Approaching the other end of the shelf, it can turn out that there is insufficient space to place a last shelf divider. All previously placed dividers have then to be adjusted by being moved a little way in either direction so as to provide room for the last shelf divider or fill the previously formed free shelf end. In this adjustment work, it is a great advantage if the shelf dividers are not fixed to the shelf, so that they do not have to be detached and refastened.
• shelf dividers Even when the shelf is ordered and the shelf dividers are placed in their respective positions, it is sometimes necessary to reorganize the shelf, in which case one or a small number of shelf dividers have to be moved, removed or attached. This is the case, for example, when the distance between two shelf dividers different dimensions. In order to facilitate such reorganization of parts of an already ordered shelf, it is therefore desirable for individual shelf dividers to be able to be detached and reattached in a new position without freeing other shelf dividers.
• the holding arrangements for the shelf dividers should be aesthetically pleasing, should not unnecessarily obstruct goods from being put onto or removed from the shelf or adjoining shelves and should be cheap and simple to produce and fit.
• US 5,657,702 describes a shelf with an arrangement for locking a number of shelf dividers to the shelf.
• the arrangement comprises a generally U-shaped channel, which is formed in the shelf and extends along the front edge of the shelf, parallel with the longitudinal direction of the shelf.
• a locking bar is disposed in the channel, parallel with the longitudinal direction of the shelf.
• the shelf dividers have a cross section in the general shape of an L, the vertical limbs of which constitute the actual divider and the horizontal limbs of which rest against the shelf.
• One end of the horizontal limb has a downward-curving flange, which is designed to jut down into the channel.
• the arrangement also comprises members for applying a locking force to the locking bar so that the flange of the divider is locked in place between the locking bar and one of the walls of the channel.
• a control member is provided to allow manual actuation of the locking bar between a locking position and a release position.
• This goods displacement is easily transmitted via tightly packed adjacent goods and can lead to a number of more distant shelf dividers toppling over or being displaced from their intended positions.
• the whole or a large part of the shelf has then to be reordered, in which case a number or all of the shelf dividers have to be returned to their original positions and the goods put back in place.
• This is not only a time-consuming and costly exercise per se, but also leads to a reluctance to reorganize already ordered shelves to accommodate new goods and packagings. Consequently, the limited shelf space is not optimally utilized, whilst, at the same time, ill- organized shelves give an unaesthetic impression and adversely affect the tendency of the store customers to select goods from these shelves.
• a further problem with the known arrangement described above is that the holding of one or more shelf dividers cannot be ensured if the thickness of the flanges of any of the shelf dividers differs from the nominal production thickness. If one flange is thinner than other flanges, a clearance is formed between this flange and the locking bar, so that the locking force cannot be transmitted to this flange. If, instead, one flange is thicker than other flanges, then a clearance is formed between the locking bar and the other flanges, in which case these receive none or only a slight locking force. A corresponding effect is obtained, of course, if the thickness or straightness of the locking bar vary along its length.
• An object of the present invention is therefore to produce a system for fixing accessories to a shelf, which system allows an empty shelf to be put simply in order and, at the same time, enables great flexibility and simplicity in the reorganization of shelf dividers in respect of an already ordered shelf.
• Another object is to produce such a system which allows individual accessories to be fastened and/or detached from the shelf even when other accessories disposed on the shelf are fixed in their respective positions.
• a further object is to produce such a system which allows accessories to be fastened and/or detached from the shelf and firmly secured to the shelf even if the members effecting the holding exhibit tolerance deviations from their nominal production measurements.
• the elastic member thus enables individual accessories to be fastened to and/or detached from the shelf without the release of other already fixed accessories. This substantially facilitates the work on reorganizing an already ordered shelf, since there is no risk of the accessories which are correctly placed being displaced, toppling over or coming loose. Moreover, the elastic member is able to absorb measurement deviations of the holding member and of the feet of the accessories without the risk of any accessory being held with a lower holding force .
• the holding member can be configured so as, in its holding position, to prevent displacement of the accessories along the shelf. This effectively stops the accessories from being mistakenly dislodged from their intended positions, for example by passing customer trolleys banging against the shelf.
• the elastic member can either be disposed on the holding member or on the accessory foot.
• the holding member is constituted by an elongated leaf spring, which constitutes the elastic member.
• the foot and the channel element of the shelf divider can be configured with interacting engagement members, which increase the stability of the accessory and which additionally prevent the accessory from toppling over when it is fixed to the shelf.
• the interacting engagement members can be configured as a projecting bead arranged on the foot or the channel element and as a corresponding recess in the other part.
• a particular advantage is herein achieved if the projecting bead is disposed on the channel element and the recess on the accessory foot .
• Such an arrangement namely prevents improper accessories, which do not have the recess, from being able to be introduced into the channel element and used together with the system.
• the channel element can be configured as an elongated profile element . This allows cheap and simple production of the channel element by extrusion.
• the channel element allows simple attachment of the channel element to the front edge of the shelf, for example by screwing or by means of double-sided adhesive tape, the system being able to be applied to and used in a host of different pre-existing shelves without special adaptation thereof.
• the channel element can be fastened in a groove or a recess disposed in the shelf.
• the invention also relates to a channel element and an accessory for use with a system according to the invention and to a shelf comprising a system or a channel element according to the invention.

• Fig. 8b illustrates how the control member 65 has been guided into its active position.
• the lever 64 has in this case been guided upward, whereupon the rear portion 62 of the actuating member 60 has rotated in the gully 41 so that the front portion 61 of the actuating member has moved along a circular arc downward in the channel.

• the leaf spring has been deformed, the front portion 61, and hence the control member 65, being detained bistably in its active position and the leaf spring 50 also being detained in its holding position until the control member 65 is manually returned to its passive position.
• the shelf divider In the holding position of the leaf spring as shown in fig. 8b, the shelf divider is therefore fixed to the shelf.
• the elasticity of the leaf spring allows the flange 26 to be deliberately brought out of its fixation position in the channel by applying an adequate force to the foot
• the configuration of the leaf spring 50 is of particular importance for preventing longitudinally directed displacement of a divider foot 24, which is held in its fixation position in the channel 36.
• the leaf spring 50 is designed to produce a sufficiently large friction force between the flange 26 and, respectively, the leaf spring 50 and the front wall 33 of the channel element to prevent moderate longitudinally directed forces acting upon the shelf divider 20 from generating displacement of the flange
• the leaf spring has tongues 54, major longitudinally directed displacements of the flange are, nevertheless, mechanically prevented.
• the width of the tongues 54 in the longitudinal direction of the channel element can correspond, for example, to about 0.25 - 0.5 times the length of the flange in the same direction.
• the slots 55 forming the interspace between the tongues are narrow. A flange 26 located in its fixation position will therefore be in contact with two to five tongues.
• those tongues which are beside the tongues bearing against the flange extend in the direction forward toward the front wall 33 of the channel element 30, past the respective end faces of the flange 26. If the flange is displaced in the longitudinal direction, one of the end faces of the flange will therefore come into contact with the side of an adjacent tongue, whereupon further displacement of the flange is mechanically blocked.
• a tongued configuration of the leaf spring also means better control over the friction force by which each flange is held in the channel.
• Each tongue acts almost as an individual spring, so that any dimensional variances amongst individual divider foot flanges does not affect the spring force applied the other flanges.
• material variations along the length of the leaf spring do not affect the spring force of adjoining tongues.
• a shelf divider foot 24 and the clamping device 30 are shown in a position corresponding to that which is shown in fig. 8b.

• This embodiment can be desirable, for example, if it is wished to prevent improper shelf dividers from being used in combination with the clamping device 30.
• a shelf divider foot which does not have the groove 28 will not be held satisfactorily in the channel when the leaf spring 50 is in its holding position.
• the projecting bead 72 By configuring the projecting bead 72 with a certain depth in relation to the opening 37 and, at the same time, modifying the characteristics of the leaf spring, it is possible, moreover, to prevent the leaf spring from being guided to its fixation position unless the flange 26 of the shelf divider foot has a sufficiently deep groove.
• FIG. 6 another embodiment is shown of a shelf divider foot forming part of a system according to the invention.
• the elastic member is configured on the flange 26 instead of on the clamping device.

• shelf dividers also applies to other types of accessories which can be fixed to a shelf, such as, for example, various goods-feeding devices, various holders for advertisement and information carriers, and various types of trays. It is further possible, for example, to configure both the clamping device and the shelf divider foot with elastic members, should this be desirable.
• the interacting engagement members disposed on the foot and the channel element can be varied in a number of different ways, for example by providing both projecting members and depressions on both the foot and the channel element.
• the clamping device can, for example, be configured for direct fastening to the vertical front side face of the shelf. It is additionally possible for a part of the shelf to form the channel element forming part of the clamping device.
