This application is the United States National Stage entry under 35 U.S.C. 371 of PCT/FI2018/050651, filed Sep. 12, 2018, which in turn claims the priority of Finnish Patent Application No. 20175839, filed Sep. 21, 2017, the contents of each of which are hereby incorporated by reference in their entirety.

FIELD OF THE INVENTION

The present invention relates to shelf support for supporting a shelf plate to a side wall of a shelf and more particularly to a shelf support according to the preamble of claim 1. The present invention also relates to an arrangement in a shelf and more particularly to an arrangement according to the preamble of claim 7.

BACKGROUND OF THE INVENTION

Conventionally a shelf comprises horizontal bottom plate or foundation, a horizontal top plate and at least two vertical side walls extending between the bottom plate and the top plate. The vertical side walls may be solid side wall boards, at least partly open side wall frames, side wall rails or the like. The vertical side wall comprises a bottom end, top end and a side wall surface extending between the bottom end and the top end. The vertical side wall may further comprise a front end and a back end extending also between the bottom end and the top end. One or more horizontal shelf plates is further arranged between the two vertical side walls. The shelf plates are supported to the side walls with one or more shelf supports. The side walls are provided with side wall apertures or side wall apertures extending perpendicularly to the side wall surface into the side wall. The side wall apertures are arranged to receive shelf support pegs. In a usual shelf, there are two adjacent lines of side wall apertures extending parallel between the bottom plate and top plates or upper end and lower end of the vertical side wall. Each line of side wall aperture comprises two or more successive side wall apertures along the lines of side wall apertures.

The shelf plates are supported to the vertical side walls by inserting shelf support pegs into the side wall apertures. The shelf support pegs comprise a pin part arranged to be inserted in to the side wall aperture in the vertical side wall, and a support part extending outside and outwards from the side wall aperture. The shelf plate is arranged against the support part and supported on the support part. The support parts are placed against the bottom surface of the shelf plate on a side edge area of the bottom surface of the shelf plate, or alternatively they are placed to a hole or groove provided on the side edge area of the bottom side surface of the shelf plate. Normally, one shelf plate is supported to two opposing vertical side walls with a four shelf support pegs, two on each opposite side edges of the shelf plate.

The conventional shelf support pegs are poor in staying in position in the side wall apertures which causes them to move and twist inside the side wall aperture. This further causes damages to the side wall aperture and the side wall aperture may be becoming larger, especially at the mouth of the side wall aperture. This further weakens ability of the shelf support peg to stay in the side wall aperture and in the preferred position in the side wall aperture. When the shelf support peg moves, also the shelf plate moves, which is undesirable and further increases the damages to the side wall aperture. The above mentioned disadvantage has been solved in the prior art by using screws or the like fasteners for fastening the shelf support to the shelf plate. However, this does not solve the problem associated with the shelf support peg moving and damaging the side wall aperture. One prior art way of alleviating the problem is using angle iron or the like for fastening the shelf plate to the vertical side wall. In this case screws are used both to fasten angle iron to the vertical side wall and the angle iron to the shelf plate. However, this very complex task and requires using tools as well as causes permanent damages to the vertical side wall and the shelf plate.

BRIEF DESCRIPTION OF THE INVENTION

An object of the present invention is to provide a shelf support and an arrangement such that the prior art disadvantages are solved or at least alleviated. The objects of the invention are achieved by a shelf support which is characterized by what is stated in the independent claim 1. The objects of the invention are further achieved by an arrangement which is characterized by what is stated in the independent claim 7.

The preferred embodiments of the invention are disclosed in the dependent claims.

The invention is based on the idea of providing a shelf support for supporting a shelf plate to a side wall of a shelf. The shelf support is a shelf support peg or the like part which is arranged to support a shelf plate from the side edges to the vertical side walls. The shelf support may be installed into a side wall aperture provided to a side wall surface of the vertical side wall. The shelf support comprises a support part arranged to be extending outside of the side wall aperture and to support the shelf plate. The support part is placed against the shelf plate, or the shelf plate is placed on the support parts. Usually the support parts support the shelf plate from the bottom surface or form grooves or holes provided to the bottom surface of the shelf plate. The shelf support further comprises a pin part arranged to be inserted into the side wall aperture. The shelf support may also comprise a stopping surface provided to the support part and the pin part is arranged to protrude from the stopping surface. In the shelf, the stopping surface is arranged to be placed against the side wall surface when the pin part is inserted into the side wall aperture. Thus, the stopping surface defines how far the pin part may be inserted to the side wall aperture. According to the present invention, the pin part extends from the stopping surface in a pin angle in relation to a direction perpendicular to the stopping surface. This means, that the pin part extends in an oblique angle from the stopping surface.

The support part may extend from the stopping surface in a direction perpendicular to the stopping surface, and thus the pin part and the support part extend in an angle relation to each other, preferably this angle corresponds the pin angle.

The stopping surface may define a stopping plane. In this embodiment, the pin part may extend from the stopping surface in the pin angle in relation to the direction perpendicular to the stopping plane. When the pin part extends from the stopping surface in the pin angle, the pin part must be inserted into the side wall aperture according to the angle, as the side wall aperture extends preferably into the side wall an aperture angle in relation to the side wall surface. Thus, the side surfaces of the side wall aperture prevent the pin part from coming out of the side wall aperture if the shelf support is pulled out of the side wall aperture in a direction perpendicular to the side wall surface. The stopping surface further prevents the shelf support from turning when the pin part is inserted into the side wall aperture when the stopping surface is against the side wall surface. Accordingly, the combination of stopping surface and the pin angle ensures also right orientation of the shelf support in the side wall aperture.

The support part may comprise an upper support surface arranged to be positioned towards the shelf plate or against the shelf plate in from the bottom surface of the shelf plate.

In one embodiment of the present invention the pin part may extend from the stopping surface parallel to the upper surface and in a first pin angle in relation to the direction perpendicular to the stopping plane when the shelf support is viewed from the support part towards the pin part. In one embodiment, the support part comprises the upper support surface arranged to be positioned towards the shelf plate. The upper support surface may define an upper support plane. The pin part may extend from the stopping surface in a direction parallel to the upper support plane and in the first pin angle in relation to the direction perpendicular to the stopping plane. In one embodiment, the support part comprises the upper support surface arranged to be positioned towards the shelf plate. The upper support surface may define an upper support plane. The pin part may extend from the stopping surface in a direction parallel to the upper support plane and in the first pin angle in relation to the direction perpendicular to the stopping plane. Accordingly, that means that the pin part extends from the stopping surface in horizontal direction and in the first pin angle when the upper support of the surface shelf support faces upwards, or is in horizontal direction. Thus, the pin part extends from the stopping surface horizontally and in laterally oblique angle, left or right, angle in relation to the direction perpendicular to the stopping surface or stopping plane.

In another embodiment, the pin part may extend from the stopping surface upwards or downwards in relation to the upper surface and in a second pin angle in relation to the direction perpendicular to the stopping plane when the shelf support is viewed from the support part towards the pin part. In one embodiment, the support part comprises the upper support surface arranged to be positioned towards the shelf plate. The upper support surface may define an upper support plane. The pin part may extend from the stopping surface upwards or downwards in relation to the upper support plane in the second pin angle in relation to the direction perpendicular to the stopping plane. Accordingly, that means that the pin part extends from the stopping surface upward or downwards horizontal direction and in the second pin angle when the upper support surface of the shelf support faces upwards, or is in horizontal direction. Thus, the pin part extends from the stopping surface in an oblique angle in relation into the horizontal direction, downwards or upwards, in relation to the direction perpendicular to the stopping surface or stopping plane.

In yet another embodiment, pin part may extend from the stopping surface parallel to the upper surface and in the first pin angle in relation to the direction perpendicular to the stopping plane when the shelf support is viewed from the support part towards the pin part. Furthermore, at the same time the pin part may extend from the stopping surface upwards or downwards in relation to the upper surface and in a second pin angle in relation to the direction perpendicular to the stopping plane when the shelf support is viewed from the support part towards the pin part. In one embodiment, the support part comprises the upper support surface arranged to be positioned towards the shelf plate. The upper support surface may define an upper support plane. The pin part may extend from the stopping surface upwards or downwards in relation to the upper support plane in the second pin angle in relation to the direction perpendicular to the stopping plane, and from the stopping surface in a direction parallel to the upper support plane and in the first pin angle in relation to the direction perpendicular to the stopping plane. Accordingly, that means that the pin part extends from the stopping surface in laterally oblique angle, left or right, in relation to the direction perpendicular to the stopping surface or stopping plane, also in an oblique angle in relation into the horizontal direction, downwards or upwards, in relation to the direction perpendicular to the stopping surface or stopping plane.

The stopping surface may define a stopping plane and the support part comprises the upper support surface arranged to be positioned towards the shelf plate. The upper support surface may define the upper support plane that is perpendicular to the stopping plane. In one embodiment of the present of the present invention the pin part may extend from the stopping surface in a direction parallel to the upper support plane and in the first pin angle in relation to a direction perpendicular to the stopping plane. In another embodiment, the pin part may extend from the stopping surface in the second pin angle in relation to the direction parallel to a plane which is perpendicular to the stopping plane and the upper support plane. In yet another embodiment the pin part may extend from the stopping surface in the first pin angle in relation to a direction perpendicular to the stopping plane in a direction parallel to the upper support plane and in the second pin angle in relation to the direction parallel to a plane perpendicular to the stopping plane and the upper support plane.

According to the above mentioned, the pin part may extend from the stopping surface horizontally and in an oblique angle left or right, when the shelf support is in normal use position in which upper support surface faces upwards. Alternatively, the pin part may extend from the stopping surface in an oblique angle upward or downwards in relation to horizontal direction, when the shelf support is in normal use position in which upper support surface faces upwards. Yet alternatively, the pin part may extend from the stopping surface horizontally in an oblique angle left or right and in an oblique angle upward or downwards in relation to horizontal direction, when the shelf support is in normal use position in which upper support surface faces upwards. In the latter case the pin part may extend from the stopping surface in an oblique angle upwards or downwards and left or right, when the shelf support is in normal use position in which upper support surface faces upwards.

In one embodiment of the present invention, the pin angle, or the first pin angle, or the second pin angle may be between 5 to 60 degrees, or 5 to 45 degrees, or 5 to 25 degrees, or 7 to 20 degrees. In one specific embodiment, the pin angle, or the first pin angle, or the second pin angle may be between 7 to 18 degrees, preferably between 8 to 16 degrees, or more preferably between 10 to 15 degrees.

The protrusion may comprise a retaining surface extending parallel to the stopping surface and upwards from the upper support surface.

The pin part extending from the stopping surface in oblique direction in relation to the direction perpendicular to the stopping surface or stopping plane may together with the mentioned protrusion effectively lock or secure the shelf plate between protrusion and the stopping surface and further to the side wall surface. Accordingly, the shelf plate may be secured to the side wall surface without additional fastening means, such as screws and without using any tools.

Furthermore, the pin part of the shelf support is arranged to extend into the side wall aperture from the support part in a pin angle in relation to the support part.

In one embodiment, the support part protrudes from the side wall surface in the direction perpendicular to the side wall surface. Therefore, the aperture angle may correspond the pin angle. In an alternative embodiment, the support part protrudes from the side wall surface in a support angle in relation to the direction perpendicular to the side wall surface. Therefore, in this embodiment the aperture angle differs the pin angle.

The two side walls comprise a vertical cross-sectional plane extending perpendicularly to the side wall surface between the bottom end and the top end and parallel to longitudinal direction of the one or more side walls between the bottom end and top end. Thus, vertical cross-sectional plane means a plane which is formed by cutting the side wall in two halves in the longitudinal direction between the bottom end and the top end. The two side walls also comprise a horizontal cross-sectional plane extending perpendicularly to the side wall surface between the first edge and the second edge and perpendicularly to longitudinal direction of the one or more side walls between the bottom end and top end.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1a shows a side view of one embodiment of a shelf support 10 according to the invention. The shelf support is formed for supporting a shelf plate to a side wall of a shelf from the lateral side edges of the shelf plate or from the lateral side edge areas. The shelf support 10 arranged to be installed into a side wall aperture provided to a side wall surface of the side wall. As shown in FIG. 1a, the shelf support 10 comprises a support part 30 arranged to extend outside of the side wall aperture. The shelf plate is supported on the support part 30. The support part 30 comprises an upper surface 34 arranged to be positioned towards the shelf plate. The shelf plate 50 is supported on or against the upper support surface 34. In normal use, the upper support surface 34 faces upwards towards the shelf plate or the bottom surface of the shelf plate. The support part 30 further comprises a stopping surface 32, which extends transversely or perpendicularly to the upper support surface 34. In FIGS. 1a, 1b and 1c, the support part 30 is a cube, however, it may be plate, bar, trip, hemisphere, round part or any other kind of part extending outside the side wall aperture.

The shelf support 10 further comprises the pin part 20 protruding from the stopping surface 32 arranged to be inserted into the side wall aperture. The pin part has a proximal end 24 from which it is connected to the stopping surface 32, and a distal end 22 away from the stopping surface 32. The pin part 20 is pin with circular cross-section. However, the pin part 20 may be any kind of pin having circular, rectangular, oval or polygonal cross-section. The length and thickness of the pin part 20 may vary depending on the size of shelf of the size of the shelf plate.

The stopping surface 32 may be any surface having larger dimensions than the side wall aperture in which the pin part 20 is inserted such that the stopping surface 32 prevents the support part 30 of entering the side wall aperture. Preferably the stopping surface 32 extends at least in vertical direction, or in the direction between the bottom end and the top end, of the side wall surface, meaning upwards and/or downwards from the pin part 20 when the upper support surface faces upwards.

As shown in FIGS. 1b and 1c, the pin part 20 extends from the stopping surface 32 in a first pin angle X in relation to a direction A perpendicular to the stopping surface 32. FIG. 1b shows a top view of the shelf support 10 with the first pin angle X. The FIG. 1c is a front view of the shelf support. Accordingly, the pin part 20 extends from the stopping surface 32 parallel to the upper support surface 34 and in the first pin angle X in relation to the direction A perpendicular to the stopping plane 32 when the shelf support 10 is viewed from the support part 30 towards the pin part 20. It may also be defined, that the upper support surface 34 defines an upper support plane, and the pin part 20 extends from the stopping surface 32 in a direction parallel to the upper support plane and in the first pin angle X in relation to the direction A perpendicular to the stopping plane. The latter is the case, when the upper support surface 34 is not smooth or a planar itself.

The first pin angle X is between 7 to 20 degrees, preferably between 7 to 18 degrees, or about 15 degrees in relation to the direction A perpendicular to the stopping surface 32 or plane.

FIG. 2a shows a side view of another shelf support 10 having the support part 30 and the pin part 20. The support part 30 comprises a collar 33 extending transversely or perpendicularly to the support part 30 and/or the pin part 20. The collar 33 forms the stopping surface 32 and the pin part 20 protrudes from the stopping surface 32 of the collar 33. In this embodiment, the pin part 20 and the support part 30 are both similar parts but they extend in the first pin angle X in relation to each other, as shown in FIGS. 2b and 2c. The pin part 20 and the support part 30 both are longitudinal and have circular cross-section. In this embodiment, the upper most line of the support part 30 forms the upper support surface 3, as shown in FIGS. 2a and 2b.

FIG. 3 shows, an alternative embodiment of the shelf support 10. IN this embodiment, the pin part 20 has roughening 21 or projections making the surface of the pin part 20 uneven. The roughening 21 increases friction between the pin part 20 and the inner surface of the side wall aperture keeping the pin part 20 more tightly inside the side wall aperture. The roughening may be utilized in any embodiment of the invention.

The shelf support 10 of FIG. 3 further comprise the stopping surface 32 and the pin part 20 extends from the stopping surface 32 of the support part 30. The support part 30 also comprises the upper support surface 34 which faces upwards and towards the shelf plate during normal use. As seen in FIG. 3, the support part 30 extends between the stopping surface 32 and the support part end 35. The support part 30 is further provided with a protrusion 36 protruding from the upper support surface 34, preferably upwards or perpendicularly from the upper support surface 34. The protrusion 36 is provided to the support part 30 at a distance T from the stopping surface 32. In this case, the shelf plate also has a support hole for receiving the protrusion 36. The support hole may be provided to the bottom surface of the shelf plate and in the first distance T from the lateral side edge of the shelf plate which is placed against the vertical side wall surface. The protrusion 36 comprises a retaining surface 38 extending in transverse direction in relation to the direction A perpendicular to the stopping surface 32 and upwards from the upper support surface. Alternatively, the retaining surface 38 may extend parallel to the stopping surface 32 and upwards from the upper support surface 36. The retaining surface 38 faces towards the pin part 20. The protrusion 36 also comprises an upper protrusion support surface 37 which is arranged to be provided towards the shelf plate, and against which the shelf plate may be supported. The upper protrusion support surface 37 may extend parallel to the upper support surface 34 or transversely or perpendicularly to the stopping surface 32. The upper protrusion support surface 37 may be arranged against bottom surface of the support hole of the shelf plate.

The side wall aperture 60 extends into the side wall 70 in direction D and in angle Q in relation to a direction B perpendicular to the side wall surface. Accordingly, the side wall aperture 60 extends inside the side wall 70 in horizontal direction and towards the first or second side edge 73, 74 of the vertical side wall.

In other words, the vertical sides wall 70 comprises a vertical cross-sectional plane extending perpendicularly to the side wall surface 76 between the bottom end 71 and the top end 72 and parallel to longitudinal direction M of the one or more side walls 70 between the bottom end 71 and top end 72.

Further, the pin part 20 extends into the side wall aperture 60 from the support part 30 in the pin angle X in relation to the support part 30, or in the pin angle X in relation to the direction A perpendicular to the stopping surface 32.

It should be noted, that in this arrangement it may also be used as the shelf support 10 a pin uniform cross section, as shown in FIGS. 10a, 10b and 10c. This shelf support comprises the pin part 20 and the support part 20, and they extend in the first pin angle X in relation to each other.

FIGS. 11a and 11b show an alternative embodiment in which the support part 30 comprises the protrusion 36 at the first distance T from the corner 31. The combination of the oblique side wall aperture, shelf support with the corner 31 and the protrusion form a solution which enables locking or securing the shelf plate efficiently to the side walls. Thus, the shelf plate is secured both in direction of the side edges 53, 54 and in a direction perpendicular to the side edges 53, 54.

The support part 30 may protrude from the side wall surface 76 in the direction B perpendicular to the side wall surface 76. The aperture angle Q corresponds the pin angle X, when the stopping surface 32 is parallel to the side wall surface 76 and against the side wall surface 76. This means the direction of the side wall aperture 60 in relation to the side wall surface 76 corresponds direction of the pin part 20 in relation to the stopping surface 32.

In a case the stopping surface 32 is not parallel to the side wall surface 76, the pin part 20 is inside the side wall aperture, the aperture angle Q may differ from the pin angle X.

The first aperture angle may be between 7 to 20 degrees, preferably between 7 to 18 degrees, or about 15 degrees in relation to the direction B perpendicular to the side wall surface 76.

As mentioned above, the side wall surfaces 76 may comprise at least one pair of adjacent side wall apertures 60, the pair of adjacent side wall apertures 60 comprise the first side wall aperture 61 and the second side wall aperture 62. In one embodiment, the first side wall aperture 61 extends parallel to the horizontal cross-sectional plane and in the first aperture angle X towards the second side edge 74 of the vertical side wall 70, and the second side wall aperture 62 extends parallel to the horizontal cross-sectional plane and in the first aperture angle Q towards the first side edge 73 of the vertical side wall 70. Alternative, the first side wall aperture 61 extend parallel to the horizontal cross-sectional plane and in the first aperture angle towards the first side edge 74 of the vertical side wall 70, and the second side wall aperture 62 may extend parallel to the horizontal cross-sectional plane and in the first aperture angle Q towards the second side edge 73 of the vertical side wall 70. In other word, the first and second side wall aperture 61, 62 extends in different directions towards each other or away from each other. Similarly, the pin parts 20 of the shelf supports 10 extend in the first pin angle X towards each other or away from each other inside the first and second side wall apertures 61, 62.

In the case of using the shelf support 10 of FIG. 12 and using side wall apertures 60 extending in different direction towards the top end 72 and bottom end 72 of the vertical side wall 70, the same may be achieved.
