Description

Technical field

The technical solution concerns a boltless shelf, ie a shelf without the use of connecting elements. Background Art

The screwless shelves known so far utilize the combination of shelves and webs without additional elements and have more complicated and technologically demanding shelves. The unit is designed for higher load capacity, uses thicker plates and the required stability is ensured by self-locking shelf and web connection by means of flat wedge tabs on the shelf, which are inserted into crimped grips in the web to create friction in one plane. The main disadvantage of this design is seen in the demands for high precision in manufacturing and is therefore more expensive. The solution does not provide a comparable stability of the whole with the solution that is the subject of this utility model application.

The essence of the technical solution

The above-mentioned drawbacks are largely eliminated by the boltless rack made up of shelf webs and shelf racks, according to this technical solution, which is based on the fact that the shelves of the shelf are provided with thumbs, on which are made semi-creamy embossments bevelled in two planes perpendicular to one another and while the L-shaped shelf webs are provided on the inside with semi-hollow embossments bevelled in two planes perpendicular to each other. Semi-annealed embossments in shelf shelves and in shelf stands ensure self-locking connection of shelf stands with shelf shelves in two levels.

The main advantage of this technical solution is seen in a self-locking joint, in which frictional forces are created in the semi-gelding spatial recesses by means of thumbs. By sliding the thumbs into similarly shaped ridges in the web, pressure is exerted on the web surface and the friction between the shelf edges of the shelf and web is increased, providing greater bond strength and overall system stability.

The method of forming the self-locking pressure of the shelf web and the shelf shelf by means of semi-rigid recesses in the shelf and the shelf web in two planes perpendicular to each other between the shelf edges of the shelf and the shelf web is a major advantage of this technical solution. The self-locking joint thus formed is stronger and provides better rigidity for the entire shelf structure. The shelf construction is simpler, the short side has only one bend and it is not necessary to point the bottom shelves of the shelf together. The press on the rack is stronger and allows the use of a thinner sheet for its production. Semi-magenta seams have a bevel in two planes, creating a combined pressure, the angles ensure self-seaming even without shelf loading. BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows an internal view of the shape of the shelf corner of the shelf, FIG. 2 shows an interior view of the shape of the shelf in the corner of the shelf stand, FIG. 5 is a sectional view of a shelf web, and FIG. Exemplary embodiments

1 to 4 is formed in such a way that the flanges 9 of the shelf 2 are provided with thumbs 6 on which the semi-emerald ridges 7 are bevelled in two planes perpendicular to one another and the abutment surfaces 1 The L-shaped racks 1 are provided on the inner side 8 with semi-alignment grooves 7 bevelled in two planes perpendicular to each other. The semi-irons 7 in the shelf 2 and in the shelf 1 provide a self-locking connection of the racks 1 to the shelves 2 in two planes. The joint is formed by inserting the thumbs 6 cut out on the edges 9 of the shelf 2 in a vertical plane as far as the stop. The distance of the axes of the thumbs 6 from the rim 9 of the opposite side of the shelf 2 is the same as the distance of the axes of the impression 5 on the shelf 1 from the adjacent inner side 8 of the shelf web L The side edges 12 inches 6 are parallel. After inserting the inches 6 into the recesses 5, the sides of the 10 semi-irregular grooves 7 in. 6 slide over each other on the same surfaces Π. a radial and axial clearance between the surfaces of the shelf flange 9 and the inner sides 8 of the shelf web 1 is defined on the shelf 5 of the shelf web 1. Friction between the surfaces 9 and 8 and the perpendicular joint is induced by the shelf 2 being pulled onto the contact surface 13 between the horizontal plane of the shelf 2 and the vertical plane of the shelf 1, thereby creating a resistance to deflection + of the shelf 2 and the shelf 1 from an angle of 90 degrees. This creates a solid self-locking joint that ensures the stability of the whole screwless rack.

Semi-emerald trims 7 have a bevel in two planes, creating a combined pressure and angular size ensuring self-alignment of the shelf even without shelf loading 2. Position 3 represents the bent side of the longer shelf side 2, while position 4 represents the bent edge of the shorter shelf side 2.

The principle of securing the stability of the boltless shelf, as shown in FIG. 5, by screwless connection of the shelf shelves 2 and the racks 1, consisting in defining the connection clearances by means of fingers 6 formed on the edges 9 of shelf shelves 2 provided with semi-gelded recesses 7, on the rack 1, they create friction in two planes perpendicular to each other, acting between the inner position of the rack 1 and the rim 9 of the shelf 2.

Industrial usability.

The boltless shelving is industrially usable in both industrial warehouses and households.
