Description

The proposal relates to furniture fittings, in particular to parts (spacers) that provide a gap between the tabletop and the vertical panel sides (supports) of tables intended for use mainly in office or office furniture.

There is a known variety of office tables, which have a gap between the tabletop and horizontal elements (sidewalls, traverses or drawers) with a decorative purpose. The gap is usually close to the thickness of the countertop. To fix the size of the gap, parts called spacers are placed in it. Since the spacers are located openly, they must possess not only functional, but also decorative qualities.

Known spacers for office desks made of two latch elements of a shaped profile, one of which is attached to the table top and the other to the table traverse (international application No. WO 2004/052148 according to class A 47 B 13/02 of 11/7/2003) . The disadvantage of a spacer is the low strength of the connection between the tabletop and the traverse, whereas office furniture, often moved along the floor, requires increased structural strength. The supply is so bad aesthetically that in the famous table it is covered with an additional decorative element.

Closest to the proposed one is a spacer for the unit for connecting the tabletop with the sidewalls, made in the form of a bar with through holes installed between the sidewalls and the tabletop fastened with threaded or eccentric couplers passing through the holes of the spacers (Kraft office furniture catalog, Germany, 2005 office catalog furniture manufactured by Point-ex, Italy, 2005-2006). A disadvantage of the known spacers is the insufficient strength of the connection of the countertop with the sidewalls. The sidewall shields are usually thinner than the countertops and when exposed to a transverse load, the screeds usually break out or destroy the top of the sidewall.

The technical task of the proposal is to increase the strength of the fastening unit of the countertop with the sidewall while ensuring decorativeness and manufacturability of the spacer.

The specified technical result is achieved by the fact that the proposed spacer of the connection unit of the tabletop with the sidewall, having through holes for screeds, is made in the form of an unequal corner, the length of which is (2-3) t, where t is the gap between the tabletop and sidewall, holes for screeds made passing across the short shelf of the corner, the thickness of the short shelf is t, and the length on the inside of the corner is the thickness of the sidewall, the length of the long shelf is (3-4) t, and the thickness of the long shelf is 0.4-0.5 of the thickness of the shield shield.

In addition, the inner side of the long shelf has a recess not reaching the edges of the shelf and the inner corner of the corner.

In addition, on the outside, a long shelf has chamfers along the free edge of the shelf and at the ends of the corner.

In addition, the width of the chamfer on the free edge of a long shelf is 1.7-2.2 times greater than the width of the chamfers at the ends of the corner.

In addition, the angle between the planes of the long shelf and the chamfer at its free end is 0.8-0.9 the angle between the planes of the long shelf and the chamfers at its ends.

In addition, the angle between the planes of the long shelf and the chamfer at its free end is 27-33 degrees.

In addition, the spacer has two decorative grooves parallel to the chamfers at the ends of the corner, located from the edges of the chamfers at a distance equal to 0.9-1.2 of the width of the chamfer, having a width of 0.3-0.6 of the width of the chamfers and a depth equal to 0.3-0.6 of their width.

The implementation of the proposed spacers in the form of an unequal angle allows you to provide high strength and good appearance of the connection with high manufacturability of the product and minimal material consumption.

The choice of the corner length within (2-3) t, where t is the size of the gap between the tabletop and sidewall, increases the reliability and rigidity of the connection, as it gives a sufficiently long connection base and allows you to pass through the spacer not one, but two or more coupling elements, what are the transverse holes in the short shelf of the corner.

The choice of the thickness of the short flange of the corner equal to t allows you to use it as an element that determines the gap between the countertop and sidewall.

The choice of the length of the short shelf on the inside of the corner equal to the thickness of the sidewall provides sufficient joint strength with minimal material consumption and eliminates the protrusion of the spacer corners into the space of the table.

The implementation of a long flange of the corner with a length of (3-4) t provides high strength joints with its good appearance.

The implementation of a long shelf corner with a thickness of 0.4-0.5 thickness of the shield supports provides high strength joints with its good appearance.

The recess on the inside of the long shelf reduces the material consumption of the product, and the recess, not reaching the edges of the shelf and the inner corner angle, ensures the strength of the spacer.

The execution of decorative elements on the outer (front) side of a long shelf in the form of chamfers and grooves simplifies the manufacture and decoration of the spacer, without noticeably affecting its strength.

All other features related to chamfers and grooves on the front side of a long shelf provide a good appearance of the product, that is, serve aesthetic purposes, without affecting the strength of the spacer. The specified limits for changing the size of chamfers and grooves are established by the expert method and are recognized as providing the best aesthetic perception of the spacer.

The essence of the proposal is illustrated by drawings.

Figure 1 shows a cross section of the proposed spacers mounted in the table, a plane perpendicular to the plane of the table and the plane of the sidewall.

Figure 2 shows a view of the proposed spacer mounted in the table from the side of the end surface of the countertop.

Figure 3 shows a view of the proposed spacer from the bottom.

The proposed spacer is a piece of unequal angular metal profile (corner) with different thicknesses of shelves. The short shelf 1 has a thickness equal to the gap t between the countertop 2 and

sidewall 3. In the shelf 1, there are at least two (three are shown in the drawing) holes 4, which serve to pass screw or eccentric couplers fastening the countertop 2 and sidewall 3. The couplers are not shown in the drawings. The free edge of the short shelf 1 faces the underframe and is not visible under the operating conditions of the table.

To ensure the strength of the spacer, the thickness of the long shelf is 0.4-0.5 sidewall thickness. To reduce material consumption from the inside, the long shelf 5 may have a recess from the inside 6. The recess 6 does not reach the edges of the shelf 5, is not visible from the outside and does not affect the appearance of the product when it is installed on the table. The recess 6 does not reach the shelf 1, so as not to weaken the junction of the shelves, which is the most loaded during lateral impacts on the sidewall. The transition from the inner side of the shelf 1 to the shelf 5 can be made with rounding, which further increases the strength of the spacer, but complicates the installation, as it requires chamfering on the sidewall 3 in the place of installation of the spacer.

The long shelf 5 faces the outer edge of the table, is visible during operation and therefore has decorative elements - chamfers 7 at the ends of the corner and 8 along the free edge of the shelf. There is no chamfer on the side adjacent to the countertop. The width of the chamfer 8 on the free edge of a long shelf is 1.7-2.2 times greater than the width of the chamfers 7 at the ends of the corner. The angle between the planes of the shelf 5 and the chamfer 8 is 0.8-0.9 the angle between the planes of the shelf 5 and the chamfer 7. The angle between the planes of the shelf 5 and the chamfer 8 is 27-33 degrees.

In addition, the shelf 5 has as decorative elements two grooves 9 parallel to the chamfers at the ends of the corner, located from the edges of the chamfers at a distance equal to 0.9-1.2 of the width of the chamfer, having a width of 0.3-0.6 width chamfer and depth equal to 0.3-0.6 of their width.

The advantage of chamfers and grooves as a decorative element of the spacer is that they do not complicate the manufacture of the product by casting, simplify polishing of open surfaces, are consistent with the rectangular elements of the table and the general rectangular shape of the spacer. It is this design that goes well with the general appearance of tables of various designs, that is, universally. All the above ratios of the sizes of grooves and chamfers are established empirically and by the method of expert evaluation are recognized as the best from an aesthetic point of view. In particular, the use of a wider and smaller angle component with the plane of the flange 5 of the chamfer on

the free edge of the shelf significantly improves the appearance of the spacer compared to the option when all the chamfers are the same. Chamfers conceals the relatively large thickness of the shelf 5, necessary to ensure rigidity and strength of the spacer and the connection node of the tabletop with the sidewall. At the same time, neither the grooves, due to their shallow depth and width, nor the chamfer, significantly reduce the strength of the spacer. The presence of chamfers reduces the material consumption of the product. The presence of grooves not only enlivens the appearance of the front part of the spacer, but also reduces the complexity of its manufacture, as it conceals possible polishing defects, which are much more noticeable on a wide smooth surface.

It is most advisable to make spacers by casting from an aluminum alloy. In this case, the surfaces of the shelves may have small - 1-2 ° casting slopes that do not affect the functional and aesthetic qualities of the product. The transverse holes 4 in the short flange 1 are drilled after casting, which is not difficult when using an aluminum alloy.
