Abstract

A shelf support structure with upright posts of sheet metal sections and horizontal braces of sheet metal sections, connecting these with each other, provides with a simple structure an inherently stable connection between the posts and the horizontal braces. The sheet metal sections of the posts have an aperture at one longitudinal side and are symmetrical in cross-section with respect to a plane crossing this aperture. The aperture is terminated on both sides by flanges protruding outwardly at right angles from the walls adjoining it and a longitudinal ledge protruding into the post is located opposite the aperture, symmetrically to the plane crossing the aperture. The horizontal braces engage with their ends into the sheet metal sections forming the posts up to the wall lying opposite the aperture and are there equipped with an indentation in whose area they embrace the longitudinal ledge in the posts in a fork-like manner.

Description

Regal

Invention relates to a kind of shelf, and this shelf have the column made from the metal plate section bar, the stull that links together with it in addition, and this stull is also made with the metal plate section bar.The metal plate section bar of column has a slit on a vertical side, the cross section of metal plate section bar is symmetrical in a plane of passing this slit.Its both sides, slit are the boundary with the flange in addition, and the wall that flange then is adjacent meets at right angles, and pulls out outward; In the wall relative with the slit, make a longitudinal fluting or convex shoulder, its protrude in the metal plate section bar and also with the plane symmetry of passing the slit, the metal plate section bar of stull then has a U-shaped or C shape cross section at least, also available its slotted hole is upwards adjusted downwards, be plugged into by its termination in the slit of column, be connected simultaneously or make attachable with flange in abutting connection with this slit.

These class shelf all are known, for example can learn from European patent document EP-A-0077885 and Deutsches Reichs-Patent document DE-A-3323503.

Be encased in the scope between the flange that two columns limit slits with its termination according to its stull of the described shelf of EP-A-0077885, it roughly reached with the wallboard back side that has flange flush and be connected securely with column by the weld seam that forms along the flange open longitudinal edge at least.

For an advantages of higher stability can be arranged between column and stull, always bearing diagonal is being set between two columns again and near its two ends, is welding along flanged lip and column according to EP-A-0077885.

By being connected between its column of the described shelf of DE-A-3323503 and the stull be make decomposable, this connection be by the wedge-type shaft coupling mode of auto-tensioning come work and by protrude or the ligulate member interact, this connections one side can then can be unclamped in stull unclamping on the column on the other hand.

Shortcoming according to these two kinds of known type shelf structure patterns is, in fact the power that works in stull can only be born by the flange of the column both sides that limit the slit, and all the other cross section scopes of this class column then can not be directly stressed.The also existing actually proof of this respect, the various construction systems of being made up of two columns and at least two stulls not only are being parallel on the direction on its plane, and all are being affected on the direction perpendicular to its plane the shape stability of above-mentioned shelf.

Task of the present invention is to eliminate above-mentioned shortcoming, formulates the shelf that a kind of front has been described in detail.Just can guarantee column and stull between have a best power transmission be connected with simple methods this moment, thereby various its shape stabilities of construction system of being made up of two columns and at least two stulls are improved.

Can implement this fixed purpose promptly by stull is encased in the metal plate section bar that constitutes column with the opposed wall in slit so that its termination is approaching according to invention, and being shaped on an otch at this place, stull just surrounds longitudinal fluting or convex shoulder on the column with forked in this otch scope.

The advantage of this structure is the termination of stull, extends through the degree of depth of the whole section bar of metal plate section bar that constitutes column, and this moment, opposed wallboard cross section always formed lateral support to having big spacing.

According to the inventive features of further formation stipulated stull to each column flange be each with a kind of rivet or be threaded fixing or fixable, the 3rd connection part then can constitute between each stull termination and column with a rivet or a screw, the side that this rivet or screw connected is a wallboard of a bending forming in the stull otch scope.This 3 are connected and have promoted the joint that almost plays the joggle effect between column and the stull to be connected to a great extent.Because the riveted joint between column and the stull and/or be threaded and can make easily and reliably with simple methods, then column and stull make together with all the other all shelf must with member just can pack with taking up space, deposit with shipping less and can assemble easily and reliably with installing.Be to make between stull and the column flange two riveted joints or be threaded to be in mutually on the same axis, and constitute a hinge together but feature of the present invention is particularly advantageous.And the 3rd riveted joint between stull tongue piece and column longitudinal fluting or the convex shoulder or be threaded can be used as hinge and effectively locks connection.Two columns and at least two stulls can make these members connection ground can be arranged mutually, turn to the parallelogram mode to be offset according to certain owing to linked together in manufactory in this case.So can make and thisly turn to parallelogram under stacked state, to pack, deposit and only need very little stacking space with shipping.So only need to make in the mounting points of shelf and thisly turn to parallelogram to become the mutual relative position of rectangular-shaped framework and column and stull can to guarantee by the 3rd riveted joint being installed or being threaded.

The structural type of addressing at last for other stable problems of shelf proves important according to invention, and the stull that is used to be connected two columns with below that is provided with above can connect a tilting depression bar and supports as reinforcing.

Simultaneously recommendable especially is that depression bar has forked termination.Depression bar can surround stull whereby, and can be connected with stull by a decomposable screw thread grafting.Play the reinforcing of depression bar effect this moment and support, can form with the metal plate section bar identical with stull.After this only making the outwardly-bent segment distance in sidewall cross section (material thickness) of its forked termination, make this support can surround the sidewall of stull.

Can prove that recommendable also had the reinforcing of depression bar effect to support, its termination otch should be made like this: take its diagonal angle working position between last lower brace if reinforce to support, then should make the abuts with wall support of the limit of its cross wall facing to stull.

Need not or add the reinforcing of bar effect and supported,, still might be fixed on sidewall between two opposed columns by on the step of longitudinal slot flange limit as girth member according to the present invention.

Fa Ming purpose also is in addition, its stress that forms when reality is used is born by the connector element that is arranged between the column in the best way, and can be delivered on the column, guarantee that meanwhile shelf have a high shape stability and stability in use.

This purpose can be by inventive features of the present invention, promptly reach by following approach, the longitudinal fluting of column or convex shoulder are equipped with suspension and/or the stopper element of using as connected member, these members are on the free side that cross section is roughly U-shaped or L shaped horizontal cross bar connecting sleeve, the part that this moment, connecting sleeve just in time surrounded column cross-section promptly be in its longitudinal fluting or convex shoulder longitudinal side wall and and the sidewall of its adjacency between that part.

Yet important under this relation also have some measures, any one vertical wall in two longitudinal side walls of column all has two wall sections that are boundary with a ladder each other, wall section and join with the wall that comprises longitudinal fluting or convex shoulder, vertical rod the width of wall section less than column last have hang and/or the width of the wall section of stopper element, the degree of depth of the ladder between the two wall sections is similar to the thickness of the side on the connecting sleeve at least.

This moment, connecting sleeve always had several projections spaced a certain distance on its side, the position of these projections and turn between angle, the garden transition position of connecting plate a segment distance is arranged, and give prominence in the side inboard, the size of projection is equivalent to the degree of depth of cross section indentation part on the column.

The inclination of the wall section of column trend with respect to the wall section or the plane be acute angle, and carry out the transition to the stud wall that is provided with longitudinal fluting or convex shoulder with the obtuse angle, plane, the sidewall of longitudinal fluting or convex shoulder then has the oblique position opposite with the wall section, no matter the trend of this sidewall is the end with respect to longitudinal fluting or convex shoulder, and still the wall Duan Jun with respect to stud wall is the obtuse angle, plane.

But important also has more like this, and the connecting sleeve side has an inclination position that is suitable for column longitudinal fluting or convex shoulder sidewall on the one hand, and projection also should adapt with the inclination position of cross section indentation part on the column in the degree of depth on the side on the other hand.

At last, to what the goods lattice had that high shape stability and stability in use play an important role be, the otch of stull termination on its contour shape be with column on the sidewall slope position of longitudinal fluting or convex shoulder mutually suitable, and also there is a segment distance termination of stull this moment between the column cross section that is adjacent on its working position.Stable supporting effect this moment is exactly to reach between the inclined wall of terminal otch in the sloped sidewall of longitudinal fluting or convex shoulder and the stull.

Also can one carry original known or by the known a kind of shelf of DE-A-99091, this shelf have column, the stull that connects with it in addition, and by be the packing purpose at the hinge of being adorned between column and the stull and when depositing, can accomplish to take up space less with shipping carry out stacked.This shelf can locking as reinforce supporting then by tilting depression bar on its working position, in addition, this known shelf with do not have important common ground according to inventing between the described shelf.

Figure 12 represents to be equivalent to the part of the shelf of Fig. 5 with stereogram, but performance is different, as

Figure 13 is by pressing a horizontal section of the local figure of Figure 12 shelf left side.

Expression has a kind of shelf 1 in Fig. 1-3, this shelf can be at least with four columns 2 that structure is identical, at least two stulls 3 and several shelf base plates 4 are formed, and can also use additional member, promptly or more accurate cut can use to reinforce support 5 and/or reinforce wall 6.

Each column in 4 columns 2 can be formed this metal plate section bar by a kind of metal plate section bar of making by crimping has a slit 7 a longitudinal side, and the cross section of metal plate section bar is symmetrical in a plane 8-8 who passes this slit 7.

7 both sides, slit of column 2 with flange 10 ' and 10 " walls 9 that are adjacent ' and 9 " meet at right angles, and pull out outward; In the wall relative 11 with the slit, make a longitudinal fluting or convex shoulder 12, its protrude in the metal plate section bar and also with the plane 8-8 symmetry of passing slit 7.Column 2 two sidewalls 13 ' and 13 " upper edge its vertically be provided with the suspension opening of uniform configuration or tongue piece 14 ' and 14 ", this respect such as Fig. 1 to 3 are clear to be illustrated.

The also available metal plate section bar of stull 3 is made, and this section bar has a U-shaped C type cross section at least, and can adjust with its vertical gap 3 ' up or down, and this respect can be seen clearly especially from Fig. 5.

Stull 3 is plugged in the section bar that constitutes column 2 by slit 7, and can make its termination 15 enter with slit 7 opposed walls 11 on, this respect is conspicuous especially from Fig. 4 and 6.The termination 15 of stull 3 simultaneously is equipped with an otch 16, makes stull can be in these otch 16 scopes surround longitudinal fluting or convex shoulder 12 on the column with forked like this, and this respect can be referring to Fig. 4.Stull 3 was carried out on 5 positions with always being connected of column 2, promptly on the one hand be two flanges 10 ' and 10 " by rivet 16 ' and 16 ", also can be undertaken by screw, a common axis line 17-17 is arranged on its position location.The fixedly connected also available rivet 18 at the 3rd position or form with a screw, its connection part is arranged between longitudinal fluting or convex shoulder 12 and the tongue piece 19, and tongue piece is (Fig. 4 to 6) that is formed by the wall of bending stull 3 in otch 16 scopes.

By riveted joint or be threaded 16 ', 16 " be connected stull 3 and column 2 with 18 and always on the points of three big spacings of being separated by, carry out, remain on position in this stable lateral support in addition and be on the one hand at two flanges 10 ' with 10 " between be to engage with longitudinal fluting or the forked of convex shoulder 12 in addition on the other hand by the termination 15 that stull has an otch 16.Guaranteed that thus this construction system that always constitutes with two columns 2 and at least two stulls 3 has a high shape stability.

A kind of effective reinforcing of this construction system can use tilting depression bar to reach by additional, and this depression bar is connected on left end and lower brace 3 right-hand members in the stull 3 as reinforcing to support, and this respect can be learnt from Fig. 2.

Diagonal brace 5 in fact can be with making with stull 3 identical metal plate section bars.This diagonal brace need only be provided with an otch 20 on each termination, just can make sidewall 21 ' and 21 " rest on the there motionless, the support 5 also with regard to available these sidewalls (in case of necessity according to corresponding bending) go to surround stull, this respect can be seen Fig. 4 and 6.

22 be connected diagonal brace 5 in the stull 3 and this construction system of being made up of two columns 2 and at least two stulls 3 is stabilized on its right angle working position, as shown in Figure 2 so can peg graft by a kind of spiral.

Except with diagonal brace or without the diagonal brace, for fixing two columns 2 of every kind of usefulness and at least two construction systems that stull 3 is formed, can also adopt the sidewall 23 that forms by sheet material, this sidewall with its arris 24 rabbet the wallboard 9 of column 2 ', 9 " with flange 10 '; 10 " between in the step, this respect is by Fig. 4 obviously as seen.Simultaneously can by arm such as Parker Kollon screw 25 the fixed-site of sidewall 23 wallboard (9 ', 9 ") and flange 10 ', 10 " between stepped portions.Parker Kollon screw is seeing through sidewall 23 near arris 24 places, shoot the flange 10 of column (2) ', 10 " in.

Fig. 7 to 10 of accompanying drawing is shown with a kind of structural type of shelf 1, this structural type just can be made according to tiny change or subsidy measure the various construction systems that are made of two columns 2 and two stulls 3 can be installed in factory in advance, takes up space less for packing and depositing with the then available parallelogram of shipping is stacked.

Just be necessary to make fully in order to achieve the above object stull 3 as two columns 2 by rivet or screw 16 ', 16 " link together on axis 17-17 position location, this connection can be movable, but also very firm.The termination 15 of two stulls 3 its with the opposed bight of diagonal respectively be arranged to have a chamfering radius 24 around hinge axis 17 ' or 24 "; this radius then can respectively extend to half cross-sectional height of stull 3 at the most; this respect can be from Fig. 7, and 9 and 10 learn.So the construction system that is made of two columns 2 and two stulls 3 according to this structure just can change parallelogram between stowed position shown in Figure 7 and working position shown in Figure 9, make the straightforward face of stull 3 terminations 15 when being in working position become support device by Fig. 9, as the support limit stop of the wall 11 of column 2, meanwhile its otch 16 is then with forked longitudinal fluting or the convex shoulder 12 of surrounding.By in field riveting between the tongue piece 19 of stull 3 and column longitudinal fluting or the convex shoulder 12 or be threaded 18, so just can fix working position by the construction system of Fig. 9, also can be and then by pack into diagonal brace 5 and/or must the time reinstall sidewall 23 and do additional the assurance.

Fig. 8 represents can make two construction systems pack, deposit and shipping by shelf 1 and affiliated diagonal brace 5 if make the sort of methods that take up space less.

From Figure 11 to 13 of accompanying drawing obviously is the further structural measure of shelf 1, can make its shape stability and stability that further raising is arranged whereby.

Figure number that while Figure 11 to 13 uses and the figure number of Fig. 1 to 10 are compared and are respectively increased by 3 10 figure places.Therefore always indicate figure number 32 at these figure upper pillar stands, stull is then represented or the like with figure number 33.

Each column 32 is made up of a kind of profile material of making by bending forming, also has a slit 37 on one vertical side, and its cross section is symmetrical in a plane 38-38 who passes this slit 37.

37 both sides, slit of column 32 with flange 40 ' and 40 " be the boundary, flange 40 ' and 40 " walls 39 that are adjacent ' with 39 " meet at right angles, and pull out outward; In the wall 41 relative, make a longitudinal fluting or convex shoulder 42, also with the plane 38-38 symmetry of passing slit 37 with slit 37.Column 32 two sidewalls 43 ', 43 " be provided with along the suspension of its vertical uniform configuration and/or stopper element 44 ' and 44 ".

Stull 33 extend in the profile material that constitutes column 32 by slit 37, and its termination 45 can also arrive on the wall 41 that is opposite to slit 37 as shown in Figure 11.The termination 45 of stull 33 is equipped with otch 46, so just can make stull surround longitudinal fluting or convex shoulder (Figure 11) on the column 32 with forked in these otch 46 scopes.Adopt being connected between stull 33 and the column 32 rivet 47 ' and 47 ", a common axis line 47 is arranged on its position location.But can also use screw at this position, to be arranged forming on the axis 47-47 between stull 33 and the column 32 being connected of can swinging.So just between column 32 and stull 33, form a kind of stable side and support, and on the one hand can be that " and the termination 45 that has an otch 46 by stull 33 on the other hand is connected with the forked joint of groove or convex shoulder 42 by two flanges 40 ' with 40.So also guaranteed this construction system that always constitutes a high shape stability is arranged by two columns 32 and at least two stulls 33.

Another kind is reinforced special effective measures to shelf 1, can realize that horizontal cross bar 36 can be on Figure 11 thus by means of horizontal cross bar 35 and 36, and horizontal cross bar 35 is then clearly seen on Figure 12.

The same with column 32 and stull 33, horizontal cross bar 35 and 36 is also made with profile material.If horizontal cross bar 35 has a Z-shaped cross section (Figure 12) in addition, then horizontal cross bar 36 just has a cross section section bar that opens wide towards the side or a C shape cross section is arranged.

Column 32 remove existing hang and/or stopper element 44 ', 44 " in addition, also have in its longitudinal fluting or convex shoulder 42 scopes and hang and/or stopper element 48, these members are made up of simple opening or otch.Simultaneously these otch always are on the bottom 49 of longitudinal fluting or convex shoulder 42, and they be at least with direct connection be configured in its sidewall 50 ' and 50 " on.

Hang and/or stopper element 48 with respect to hang and/or stopper element 44 ' and 44 " be interconnected on its height, this respect is by seeing on Figure 12.

" (seeing Figure 12 and 13), a similar connecting sleeve 52 then is the termination (Figure 11) that is in horizontal cross bar 36 to be fixed with a connecting sleeve 51 on each termination of horizontal cross bar 35.

" or 52 have one and be roughly U-shaped or L shaped cross section and make plate connecting sleeve 51.

Connecting sleeve 51 by Figure 12 and 13 " has two sides 53 and 54 to link into an integrated entity together by a connecting plate 55.The side 53 that has less width this moment is made the engagement member 56 of integrated, its shape is as the crooked hook that forms on the side plane, and this hook can engage in the bottom 49 of longitudinal fluting 42 with opening or the otch as fixed component 48 usefulness.Connecting sleeve 51 " the side 54 of broad can support several engagement members; and this side make have several for example three the interval is stacked and position 71 is reinforced in direction compacting outwardly; an opening 72 is respectively arranged in the scope of top, above-mentioned position, and on side 54 planes, still has a downward hook spare 73 on the other hand.

With connecting sleeve 51 " when being hanging on the column 32, its hook 73 just enter from above the suspension of column 32 and/or stopper element 44 ' or 44 " the back, hang and/or stopper element 44 ' or 44 " then give prominence to by opening 72." make this layout shape stability is increased, this reinforces position 71 and reaches by being provided with compacting connecting sleeve 51, makes in addition to be connected with the joint of column 32 to improve.

Because these compacting reinforcing position 71 sizes are bigger, so also can form good face of weld to horizontal cross bar 35.

" and the acting in conjunction of a column 32 also is obviously visible by Figure 13 by each connecting sleeve 51 of Figure 12.But this moment, Figure 13 clearly show that column 32 can also have the moulding of a kind of Figure 11 of being different from.

Press the profile shapes of Figure 11, the wall section of column (32) (62 ' or the inclination of 62 ") trend be acute angle with respect to the plane of wall section (63 ' or 63 "), and carry out the transition to the stud wall (41) that is provided with longitudinal fluting or convex shoulder (42) with the obtuse angle, plane, the sidewall of longitudinal fluting or convex shoulder (42) (50 ' or 50 ") then have and the opposite oblique position of wall section (62 ' or 62 "), this sidewall (50 ' or the trend of 50 ") no matter be the end (49) with respect to longitudinal fluting or convex shoulder (42), still with respect to the wall section of stud wall (41) (41 ' or 41 ") all be the obtuse angle, plane.

By at connecting sleeve 51 " go up suitably configuration side 53 and projection 70, just can guarantee with column have one good especially, promptly play the joint connection of wedge-like effect.

Because press Figure 13 not only the sidewall 50 of longitudinal fluting or convex shoulder 42 ' or 50 "; and there is a matched oblique position additional thereon otch 46 sides in the termination 45 of stull 33; this position can be in the working position of stull 36 with the tight mutually support of wedge-like; and the mutual power transmission that forms thus is good; although the termination of stull 33 45 and column 32 wall cross sections 41 '; 41 " internal surface keep certain intervals, this respect such as Figure 13 can clearly see.

A kind of similar in appearance to connecting sleeve 51 ' structure also have the connecting sleeve 52 of horizontal cross bar 36, that is to say that this connecting sleeve has a U-shaped or L shaped cross section, this cross section has two parallel sides 58 and 59 and one and interconnects the connecting plate 60 that is integral.The width of side 58 is little than side 59, and only side 59 is being born the connected member 61 of shape as hook in this case, and this hook is bending forming on edge surface then.

Connecting sleeve 52 is inserted in the longitudinal fluting or convex shoulder 42 of column 32 with its side 59 that has engagement member 61, and shape can allow the suspension and/or the fixed component 48 that are formed by opening or otch extend through in the bottom 49 of longitudinal fluting or convex shoulder 42 as the engagement member 61 of hook, and hooks stretching there.This moment side 59 abut against outside a sidewall 50 of longitudinal fluting or convex shoulder 42 ' and 50 " on; and meanwhile 58 of sides abut against outside a longitudinal side wall 43 ' or 43 " on, and cross section indentation position 62 ' or 62 " size; will than longitudinal side wall 43 '; 43 " on bear that supporting is hung and/or stopper element 44 ' or 44 " position 63 ' or 63 " size little, the difference of two sizes is suitable with the material thickness of the side 58 of connecting sleeve 52 at least.Simultaneously this cross section indentation position 62 ' or 62 " width can be according to the width adjustment (Figure 11) of connecting sleeve 58.
