Description

FIELD OF THE INVENTION

The present invention relates to a base member for supporting a shelf and forming a joint in the shelf comprising at least one bottom plate and at last two 5 side walls, and more particularly to a base member according to preamble of claim 1. The present invention further relates to a shelf system comprising two or more vertical side walls and at least one horizontal bottom plate, and more particularly to a shelf system according to preamble of claim 9.

BACKGROUND OF THE INVENTION

Conventional shelfs, such as book shelfs, are composed of a horizontal bottom plate, two or more side walls extending in vertical direction and a horizontal top plate. The side walls are attached on the top surface of the bottom plate with screws, flanges, angle irons or special fasteners such that the bottom end 15 face of the side wall is on the top surface of the bottom plate. The top plate is attached similarly such that the bottom surface of the top plate is against the top end face side walls. Further one or more shelf plates are arranged between two side wall and between the top and bottom plates. The shelf plates are supported to the side walls with two or more detachable shelf supports such that the position of 20 the shelf plates may be changed.

One of the disadvantages associated with the prior art shelfs is assembly of the shelfs comprising several separate pars is complex. The assembly of the prior art shelfs comprises several assembly steps and requires use of different kinds of tools and a number small fasteners. Assembling of prior art shelf 25 cannot be done by one person but needs at least two persons which is a substantial disadvantage. Furthermore, the prior art shelfs very difficult or close to impossible to disassemble and to assemble again.

The base member comprises a base plate having 5 top surface and a bottom surface. The base member also comprises at least one connection part arranged to form a bottom joint between the base plate and a bottom plate of the shelf, the at least one connection part being provided on the top surface of the base plate. The base member further comprises at least one standing support provided to the top surface 32 and arranged to form a side wall joint 10 between the base plate 31 and the side wall 60. The at least one standing support may be base protrusion arranged to protrude from the top surface of the base plate and to form the side wall joint between the base plate and a side wall, or a support aperture provided to the top surface of the base plate and arranged to extend into the base plate for forming the side wall joint between the base plate and a side wall. 15 Accordingly, the at least one connection part is arranged to connect the horizontal bottom plate to the base member and the standing support is arranged to support the vertical side wall in an upright position to the base member. Therefore, the horizontal bottom plate and the vertical side wall are connected and joined together via the base member. Further, the at least one connection part and the at 20 least one standing support may place and hold the horizontal bottom plate and the vertical side wall in place during the assembly.

The top surface of the base plate has length direction and a width direction. In one embodiment of the present invention the at least one connection part and the standing support are spaced apart from each other on the top surface 25 in the width direction of the top surface. This means thatthe at leastone connection part and the standing support are not in same line in the length direction of the top surface. In one embodiment, the at least one connection part and the standing support are spaced apart from each other on the top surface in the length direction of the top surface. This means thatthe at least one connection part and the standing 30 support are not in same line in the width direction of the top surface. In a still another embodiment, the at least one connection part and the standing support are spaced apart from each other on the top surface in the width and length direction of the top surface.

As shown in figure 16, bottom end face 62' of the vertical side wall 60 is supported directly on the top surface 32 of the base plate 31 and between the two horizontal bottom plates 50. 35 This is advantageous for the support of the vertical side wall 60, especially during assembling. When the horizontal bottom plates 50 are installed on the base

20175837 prh 21 -09- 2017 member 30 they provide lateral support for the vertical side wall 60. Thus one person can easily assemble the shelf, as the vertical side wall may stand without holding.

Figure 17 shows one shelf or shelf system 100 in assembled condition.

The horizontal bottom plates 50 and the vertical side walls 60 are all supported on the base members 30 and connected to each other with the base members 30. Shelfs plates 72 and the top plates 70 are arranged between the adjacent two vertical side walls 60 and supported to the them with shelf supports 74.

The plate ends 53 and 57, or end faces, are further provided with joint grooves 58 forming recesses for receiving the alignment parts 36, 37 or tenons in horizontal direction. This enables the adjacent horizontal bottom plates 50 to be 15 placed in butt joint such that the end faces are against each other on the top surface 32 of the base plate 31, as shown in figure 19. The support grooves 57 allow the standing support 34 to protrude from the top surface 32 of the base plate 31 above the upper surface 51 of the horizontal bottom plates 51. Similarly, the joint grooves 58 allow the alignment parts 36, 37 to protrude from the top surface 32 of the base 20 plate 31 above the upper surface 51 of the horizontal bottom plates 51.

Figure 20 shows schematically an end side view of the embodiment of figure 19.
