Abstract
The vertically and horizontally running bars (10 . . . 12) of a shelf system are formed from U-section rods (20), whereby free-standing shelf columns (11) have a box shape formed from two U-profile rods (20). The same standard profile is thus used for the formation of differing shelf components.
Description
Tegometall (international) AG - PCA-38656 Translation of International Patent Application PCTfEPa~/Oi9G5 Rack system Description Rack systems have to be adaptable to the individual requirements flf the user.
For instance, the height, width and depth and the number of shelves depend on the respective usage of the rack. It is also desirable for racks which have already been constructed to be easily extended or converted.
The profiles of the components used for the rack, in particular of the vertically and horizontally extending bar elements (columns, supports, cross members) determine the load bearing capability of the rack. Racks for relatively heavy loads require correspondingly stable components. On the other hand, use of excessively solid components for lightweight to racks results in an unnecessarily heavy, material-intensive and inelegant structure.
This makes it necessary to provide the required number of different components for the purpose of constructing different stable racks, which affects storage correspondingly.
The object of the invention is to specify a rack system which can be assembled from the smallest possible number of different components.
is This object is achieved by the invention specified in claim 1. The rack bar element provided in accordance with the latter is made up of U-profile bars, which can also be used alone, preferably as rack wall uprights. A basic element is thus provided from which a plu rality of different rack components can be formed. Due to their profile, the components made up of two U-profile bars are distinguished by a high level of inherent rigidity and 2o allow the construction of stable frame structures.
The developments of the invention according to claims 3 to 6 are advantagec~,rs in terms of strength and practical usage. The configuration according to claim 3 gives rise to a profile which has particular load-bearing strength and is easy to install.
claims 7 and 8 relate to advantageous possible configurations for connecting the bar 25 elements according to the invention.
The features specified in claims 9 to 11 are expedient for relatively lightweight racks intended for the private sector.
Advantageous embodiments of the invention are explained in more detail herein-below with reference to the drawings, in which:
3o Fig. 1 is an overall view of a rack assembled accordance to the invention, Fig. 2 shows a component for connecting two U-profile bars to form a box profile, Fig. 3 shows an arrangement for connecting two rack columns to form a rack stand, and Figs. 4 to 9 show connecting elements for use between various horizontal and vertical rack elements.
The rack shown in Fig. 1 has a frame which is constructed from two rear wall uprights 10, two free-standing front columns 11 and horizontal cross members 12. Each s wall upright 10 is connected to an associated column 11 via struts 13 to form a lateral rack stand 14.
The wall uprights 10 are provided with slots 15 into which brackets 16, 17 are fitted for the purpose of receiving shelves 18, 19. Some of the shelves 18 have a depth corre-sponding to the depth of the rack stands 14 and, in this case, may be connected at their front corners to the columns 11. Alternatively, as illustrated for the intermediate shelf 19 in Fig.
1, they may have a smaller depth and supported entirely by the correspondingly shorter brackets 17.
The wall uprights 10 are formed from U-profile bars 20 which are cut to the respec-tively desired length from material supplied by the metre. The U-profile is produced by t5 bending sheet steel of a thickness of, e.g., 1 to 2 mm, the central web (25 in Fig. 2) having a width of, e.g., 20 to 40 mm, preferably 30 mm, and the lateral legs (24 in Fig. 2) having a height of, e.g., 20 to 23 mm, preferably 23.5 mm. The ratio of web width to leg height is between 0.5 and 1.
The slots punched into the central web 25 of the U-profile bar 20 are arranged at a 2o spacing of, e.g., 50 mm. They extend in alignment with the longitudinal centre line of the central web 25 and each have a length of, e.g., 30 mm. Circular bores 21, which are coun-tersunk or recessed from the outside of the profile to receive countersunk head screws, are provided at mutual distances of, e.g., 400 mm, centrally between two adjacent slots 15.
The rear wall uprights 10 serve for fastening the rack, for example, on a building 2s wall. In the embodiment shown in Fig. 1, cross members 12 are formed from the same U-profile bars 20.
Furthermore, the front columns 11 of the rack according to Fig. 1 are also made up of two U-profile bars 20. In the embodiment shown, the columns 11 have a box profile which is produced by interconnecting two U-profile bars 20 with mutually facing profile so legs 24.
According to Fig. 2, two U-profile bars 20 are connected by a spacer arranged in the interior of the box profile and having the form of a sleeve 22, which is cylindrical or pris-matic over most of its length and has a widened end flange 23 at both ends.
The overall length of the sleeve is equal to twice the inner height of the profile legs 24. The diameter of 3s the end flanges 23 is somewhat smaller than the inner width of the central webs 25 of the profile bars. In the embodiment illustrated in Fig. 2, connection takes place by means of two countersunk head screws 26 each passing through a bore 21 in the central web 25 of the relevant U-profile bar 20 and engaging in a central threaded bore 27 of the sleeve 22.
In an alternative embodiment (not shown), the sleeve may have a smooth through bore with a continuous screw passing through it, the screw engaging, by way of its head, in s the bore 21 of one U-profile bar 20 and being fixed at its free end by a nut which clamps the other U-profile bar 20.
In another alternative embodiment (not shown), the sleeve may consist of plastic with a smooth through-passage bore in which self tapping screws engage.
Instead of the box profile assumed in Figs. 1 and 2, it is also possible for two U-profile bars 20 to be assembled into an I-profile, in which case the central webs 2~ of the two U-profile bars are simply positioned against one another and screwed to one another.
According to Fig. 3, the struts 13 connecting the two vertical bar elements (rear wall upright 10 and front column 11) of a rack stand 14 comprise bars which are flat or, in order to increase their rigidity, longitudinally bent and which are provided at each end with a hook 30 which is open at the bottom for engaging in a corresponding slot 15 of the wall upright or column 11.
In order to secure this engagement, use is made of securing elements 31 which each have a hook 32 which is open at the top and by means of which they each engage from beneath in a slot 15 of the wall upright 10 or column 11. Once fitted, the securing elements 31, as is indicated in Fig. 3, are screwed to the end regions of the struts 13.
Figs. 4 to 9 illustrate gusset-plate-like connecting elements as can be used for con-necting various rack elements at the locations indicated in Fig. 1.
The gusset plates 40, which are illustrated in a pair in Fig. 4, each comprise a rect angular piece of sheet metal which has been angled twice along a longitudinal edge. Two 2s hooks 41 are formed in the resulting flange 42, which is parallel to the plane of the piece of sheet metal. These gusset plates 40 serve for the installation, for example, of side walls (not shown) which close off the rack stands 14.
The double angling results in the outer surface of the gusset plates 40 being located in the plane of the outer legs 24 of the wall uprights 10 and of the U-profile bars 20 which 3o form the columns 11. At the same time, the double angling results in the gusset plates 40 being secured in position in relation to the central webs 25 of the U-profile bars 20.
The gusset plates 50 illustrated in Fig. 5 are similar to those of Fig. 4, with the exception that they are essentially triangular rather than rectangular.
The gusset plates 60 of Fig. 6 are, in a manner similar to those of Fig. 4, rectangular ~s and are each angled once along one edge, this resulting in a flange 62 provided with two hooks 61. The hooks 61 again serve for fitting into two slots 15 of a U-profile bar 20, the shape of the gusset plates 60 being intended for fitting connecting or covering elements in a plane which extends parallel to the plane of the central webs 25 of the profiles.
The gusset plates 70 of Fig. 7 are similar to those of Fig. 6, but are essentially trian-gular rather than rectangular.
s The essentially triangular gusset plate 80 shown in Fig. 8 is formed from a planar piece of sheet metal and, according to Fig. 1, serves for connecting, for example, a cross member 12 to the wall uprights 10. .
The likewise essentially triangular gusset plate 90 shown in Fig. 9 is provided with two hooks 91 on one edge, again for fitting into two slots 15 of a U-profile bar 20, and has Io essentially the same purpose as the gusset plate 40 of Fig. 4; however, it does not have any double angling and is suitable for connecting locations at which the alignment of the rack elements to be connected to one another is achieved by other means.
All the gusset plates 40 ... 90 are provided with a plurality of holes, which make it possible to fit two screw connections in the horizontal, vertical or diagonal direction. The is diagonal direction is suitable, in particular, for fastening diagonal stiffening struts as are expedient, in particular, for free-standing racks.
For instance, the height, width and depth and the number of shelves depend on the respective usage of the rack. It is also desirable for racks which have already been constructed to be easily extended or converted.
The profiles of the components used for the rack, in particular of the vertically and horizontally extending bar elements (columns, supports, cross members) determine the load bearing capability of the rack. Racks for relatively heavy loads require correspondingly stable components. On the other hand, use of excessively solid components for lightweight to racks results in an unnecessarily heavy, material-intensive and inelegant structure.
This makes it necessary to provide the required number of different components for the purpose of constructing different stable racks, which affects storage correspondingly.
The object of the invention is to specify a rack system which can be assembled from the smallest possible number of different components.
is This object is achieved by the invention specified in claim 1. The rack bar element provided in accordance with the latter is made up of U-profile bars, which can also be used alone, preferably as rack wall uprights. A basic element is thus provided from which a plu rality of different rack components can be formed. Due to their profile, the components made up of two U-profile bars are distinguished by a high level of inherent rigidity and 2o allow the construction of stable frame structures.
The developments of the invention according to claims 3 to 6 are advantagec~,rs in terms of strength and practical usage. The configuration according to claim 3 gives rise to a profile which has particular load-bearing strength and is easy to install.
claims 7 and 8 relate to advantageous possible configurations for connecting the bar 25 elements according to the invention.
The features specified in claims 9 to 11 are expedient for relatively lightweight racks intended for the private sector.
Advantageous embodiments of the invention are explained in more detail herein-below with reference to the drawings, in which:
3o Fig. 1 is an overall view of a rack assembled accordance to the invention, Fig. 2 shows a component for connecting two U-profile bars to form a box profile, Fig. 3 shows an arrangement for connecting two rack columns to form a rack stand, and Figs. 4 to 9 show connecting elements for use between various horizontal and vertical rack elements.
The rack shown in Fig. 1 has a frame which is constructed from two rear wall uprights 10, two free-standing front columns 11 and horizontal cross members 12. Each s wall upright 10 is connected to an associated column 11 via struts 13 to form a lateral rack stand 14.
The wall uprights 10 are provided with slots 15 into which brackets 16, 17 are fitted for the purpose of receiving shelves 18, 19. Some of the shelves 18 have a depth corre-sponding to the depth of the rack stands 14 and, in this case, may be connected at their front corners to the columns 11. Alternatively, as illustrated for the intermediate shelf 19 in Fig.
1, they may have a smaller depth and supported entirely by the correspondingly shorter brackets 17.
The wall uprights 10 are formed from U-profile bars 20 which are cut to the respec-tively desired length from material supplied by the metre. The U-profile is produced by t5 bending sheet steel of a thickness of, e.g., 1 to 2 mm, the central web (25 in Fig. 2) having a width of, e.g., 20 to 40 mm, preferably 30 mm, and the lateral legs (24 in Fig. 2) having a height of, e.g., 20 to 23 mm, preferably 23.5 mm. The ratio of web width to leg height is between 0.5 and 1.
The slots punched into the central web 25 of the U-profile bar 20 are arranged at a 2o spacing of, e.g., 50 mm. They extend in alignment with the longitudinal centre line of the central web 25 and each have a length of, e.g., 30 mm. Circular bores 21, which are coun-tersunk or recessed from the outside of the profile to receive countersunk head screws, are provided at mutual distances of, e.g., 400 mm, centrally between two adjacent slots 15.
The rear wall uprights 10 serve for fastening the rack, for example, on a building 2s wall. In the embodiment shown in Fig. 1, cross members 12 are formed from the same U-profile bars 20.
Furthermore, the front columns 11 of the rack according to Fig. 1 are also made up of two U-profile bars 20. In the embodiment shown, the columns 11 have a box profile which is produced by interconnecting two U-profile bars 20 with mutually facing profile so legs 24.
According to Fig. 2, two U-profile bars 20 are connected by a spacer arranged in the interior of the box profile and having the form of a sleeve 22, which is cylindrical or pris-matic over most of its length and has a widened end flange 23 at both ends.
The overall length of the sleeve is equal to twice the inner height of the profile legs 24. The diameter of 3s the end flanges 23 is somewhat smaller than the inner width of the central webs 25 of the profile bars. In the embodiment illustrated in Fig. 2, connection takes place by means of two countersunk head screws 26 each passing through a bore 21 in the central web 25 of the relevant U-profile bar 20 and engaging in a central threaded bore 27 of the sleeve 22.
In an alternative embodiment (not shown), the sleeve may have a smooth through bore with a continuous screw passing through it, the screw engaging, by way of its head, in s the bore 21 of one U-profile bar 20 and being fixed at its free end by a nut which clamps the other U-profile bar 20.
In another alternative embodiment (not shown), the sleeve may consist of plastic with a smooth through-passage bore in which self tapping screws engage.
Instead of the box profile assumed in Figs. 1 and 2, it is also possible for two U-profile bars 20 to be assembled into an I-profile, in which case the central webs 2~ of the two U-profile bars are simply positioned against one another and screwed to one another.
According to Fig. 3, the struts 13 connecting the two vertical bar elements (rear wall upright 10 and front column 11) of a rack stand 14 comprise bars which are flat or, in order to increase their rigidity, longitudinally bent and which are provided at each end with a hook 30 which is open at the bottom for engaging in a corresponding slot 15 of the wall upright or column 11.
In order to secure this engagement, use is made of securing elements 31 which each have a hook 32 which is open at the top and by means of which they each engage from beneath in a slot 15 of the wall upright 10 or column 11. Once fitted, the securing elements 31, as is indicated in Fig. 3, are screwed to the end regions of the struts 13.
Figs. 4 to 9 illustrate gusset-plate-like connecting elements as can be used for con-necting various rack elements at the locations indicated in Fig. 1.
The gusset plates 40, which are illustrated in a pair in Fig. 4, each comprise a rect angular piece of sheet metal which has been angled twice along a longitudinal edge. Two 2s hooks 41 are formed in the resulting flange 42, which is parallel to the plane of the piece of sheet metal. These gusset plates 40 serve for the installation, for example, of side walls (not shown) which close off the rack stands 14.
The double angling results in the outer surface of the gusset plates 40 being located in the plane of the outer legs 24 of the wall uprights 10 and of the U-profile bars 20 which 3o form the columns 11. At the same time, the double angling results in the gusset plates 40 being secured in position in relation to the central webs 25 of the U-profile bars 20.
The gusset plates 50 illustrated in Fig. 5 are similar to those of Fig. 4, with the exception that they are essentially triangular rather than rectangular.
The gusset plates 60 of Fig. 6 are, in a manner similar to those of Fig. 4, rectangular ~s and are each angled once along one edge, this resulting in a flange 62 provided with two hooks 61. The hooks 61 again serve for fitting into two slots 15 of a U-profile bar 20, the shape of the gusset plates 60 being intended for fitting connecting or covering elements in a plane which extends parallel to the plane of the central webs 25 of the profiles.
The gusset plates 70 of Fig. 7 are similar to those of Fig. 6, but are essentially trian-gular rather than rectangular.
s The essentially triangular gusset plate 80 shown in Fig. 8 is formed from a planar piece of sheet metal and, according to Fig. 1, serves for connecting, for example, a cross member 12 to the wall uprights 10. .
The likewise essentially triangular gusset plate 90 shown in Fig. 9 is provided with two hooks 91 on one edge, again for fitting into two slots 15 of a U-profile bar 20, and has Io essentially the same purpose as the gusset plate 40 of Fig. 4; however, it does not have any double angling and is suitable for connecting locations at which the alignment of the rack elements to be connected to one another is achieved by other means.
All the gusset plates 40 ... 90 are provided with a plurality of holes, which make it possible to fit two screw connections in the horizontal, vertical or diagonal direction. The is diagonal direction is suitable, in particular, for fastening diagonal stiffening struts as are expedient, in particular, for free-standing racks.
