UNIT ARRANGEMENT WITH A 19-INCH FRAME

Abstract

Electrical and electronic devices are often installed in so-called racks. Racks of this type are shelf-like frames into which the devices are inserted and can be fastened, for example by means of screws. The racks commonly provide a pair of support rails for each device, upon which rails the device can be placed and can be inserted into the rack. The device can be subsequently fixed to the rack, for example screwed in. Within the scope of the invention, a device arrangement (1) is disclosed comprising at least one stacking device (4), wherein the stacking device (4) has adjustable feet (15) on the bottom surface (11) for supporting on a placement surface, comprising a base device (3), wherein the at least one stacking device (4) is arranged on the base device (3) so that these form a device tower (13), wherein the adjustment feet (15) of the stacking device (4) stand on the base device (3), wherein the device arrangement (1) comprises a 19-inch frame (2) and the stacking device (4) and the base device (3) are designed as insert devices with front plates (6) for the 19-inch frame (2), wherein the base device (3) and the at least one stacking device (4) are arranged as a device tower (13) in the 19-inch frame (2), and wherein the front plates (6) are connected to the 19-inch frame (2).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Further features, advantages and effects of the invention can be gathered from the following description of a preferred exemplary embodiment of the invention and from the accompanying FIGURE, in which:

[0024] FIG. 1 shows a schematic view from the rear side of a unit arrangement forming an exemplary embodiment of the invention.

DETAILED DESCRIPTION

[0025] FIG. 1 shows a schematic plan view as seen from a rear side of a unit arrangement 1 forming an exemplary embodiment of the invention. FIG. 1 also shows a detail D of the unit arrangement 1.

[0026] The unit arrangement 1 has a 19-inch frame 2, in which a base unit 3 and two stacking units 4 are arranged. The unit arrangement may be designed, for example, in the form of a server cabinet, a laboratory cabinet, a control cabinet, etc.

[0027] The base unit 3 and the stacking unit 4 are each designed in the form of 19-inch rack-mounting units and have a cuboidal unit body 14 and a front panel 6. The front panel 6 is arranged in an upright manner and covers a front side of the cuboidal unit body 14. At the sides, the front panel 6 projects beyond both sides of the unit body 14.

[0028] The 19-inch frame 2 exhibits a shelf or rack construction and comprises four corner profiles 5, of which only two are evident from the plan view. The corner profiles 5 are arranged vertically and define a rectangular or square surface area. A width B of the 19-inch frame 2 is dimensioned such that the front panel 6 with a width b of 19 inches can be placed in position in a precisely fitting manner. In this example, the width B, measured as the outer width of the 19-inch frame 2, is likewise precisely 19 inches.

[0029] First mechanical interfaces 7 are distributed vertically, in the corner posts 5 of the 19-inch frame 2 in the form of through-openings in a unit spacing appropriate for 19-inch frames. For example, three first mechanical interfaces 7 each spaced apart by 0.625 inches are distributed over a region of 1.75 inches such that the vertical spacing between the centers of the three first mechanical interfaces 7 is 1.25 inches.

[0030] The front panels 6 carry second mechanical interfaces 8, for example through-openings, which are adapted to the unit spacing of the first mechanical interfaces 7 such that the second mechanical interfaces 8 coincide with the first mechanical interfaces 7. The first mechanical interfaces 7 have a center-to-center spacing in horizontal direction 18 of 5/16 inches (465.14 millimeters).

[0031] The base unit 3 stands on two carrying rails 9, which in the plan view shown have an L-shaped cross section, the base unit 3 resting on a horizontal limb of the carrying rails 9.

[0032] The base unit 3 and the stacking units 4 each have a top side 10 and a bottom side 11. The top side 10 is arranged in each case at the same height as, and/or in alignment with, the upper edge of the front panel 6. In particular, the top side 10 terminates flush with the upper edge of the front panel 6. It would also be possible for the top side 10 to be somewhat lower than the front panel 6, in which case the front panel 6 projects to a slight extent, e.g. by less than 1 mm. The bottom side 11 is set back heightwise in relation to the lower edge of the front panel 6, and therefore, in relation to the bottom side 11, the front panel 6 projects beyond the entire width of the unit, or forms a skirt, in a peripheral region 12.

[0033] The base unit 3 has its bottom side 11 resting, in a peripheral region 12, on the upper side of the carrying profiles 9. In the plan view shown, the carrying profiles 9 and the peripheral region 12 are arranged in an overlapping manner.

[0034] The stacking units 4 are arranged on the base unit 3 in a unit tower 13, a first stacking unit 4 therefore being arranged on the base unit 3 and a further stacking unit 4 being arranged on the first stacking unit 4.

[0035] The stacking units 4 have positioning feet 15, which are arranged on the bottom side 11, in particular underside. The positioning feet 15 can be screwed to the stacking unit 4 or connected integrally thereto. The positioning feet 15 are of frustoconical design, wherein the large diameter is arranged on the stacking unit 4 and the small diameter stands on the base unit 3 or, in the case of the upper stacking unit 4, stands on the central stacking unit 4. As an alternative to this, it is also possible for the positioning feet 15 to be of cylindrical design or to be cylindrical with rounding at the positioning surface. The positioning feet 15 are arranged in recessed regions 16, which are designed in the form of stamped regions in a metal baseplate, which forms the bottom side 11. As far as a height of the positioning feet 15 is concerned, at least 25 percent, preferably at least 40 percent, of the height of the positioning feet 15 is recessed in the recessed regions 16, and therefore it is only the remaining part of the positioning feet 15 which projects out. For example, the height of the positioning feet 15 is 5.5 mm, with the recessed depth being 2 mm, in which case the spacing between the bottom side of the stacking unit 4 and the upper side of the unit arranged below it is 2 mm.

[0036] The overall length of the positioning feet 15 is dimensioned such that, in the loaded state shown, said positioning feet bridge the spacing between the bottom side 11 and the top side 10 of the unit located beneath, in particular the stacking unit 4 or base unit 3.

[0037] The recessed regions 16 ensure a sufficient axial length or height for the positioning feet 15, and it is therefore the case that, on the one hand, these keep an intermediate gap 17 between the bottom side 11 and the top side 10 small and, at the same time, can provide for a sufficient amount of resilient deflection for the mechanical decoupling of the units 3, 4. In particular, the positioning feet 15 and the recessed regions 16 are coordinated with one another such that the front panel 6 can be screwed to the corner profiles 5 in a tilt-free manner. As an option, provision may be made for a spacing measurement 18 to be established between the front panels 6, which, in accordance with different requirements, should be equal to, or greater than, 0 mm and smaller than 1 mm.
