Abstract
Description
- This invention relates to a load support arrangement and is particularly, though not exclusively, applicable to shelf storage systems based on a cantilever support.
- In the provision of shelving systems for storage, in order to impart flexibility to the system, -there are provided upright members to which a cantilever unit is secured so as to be adjustable. With a cantilever system, it is necessary for the cantilever arms to be secured at the support end and the arms have been made adjustable by providing either a finite number of different positions at which the cantilever arms can be fixed or, where completely variable adjustment is required, the fixing has relied upon simple clamping arrangement to hold it in place.
- The first system has the disadvantage of only relatively small numbers of adjustment positions while the latter system has the disadvantage of requiring the use of relatively strong clamps to avoid any slipping of the cantilever arm or in requiring set screw- like arrangements, whereby slipping is prevented by the fact that the screw makes a dent into the vertical support.
- Even then, the security of the cantilever arm depends upon the tightness of the clamp or screw and the weight of the load which is placed thereon.
- In our copending Application No. 82303280.0 we have proposed an arrangement in which the weight of the load has been used to increase security of the arm and additionally a clamping arrangement for the arm has been incorporated in the _system.
- While the construction proposed in our prior Application has proved eminently satisfactory for use in the storage of relatively large and heavy loads, the cost of such an arrangement is only justified where loads to be stored are above a minimum size or weight.
- The present invention seeks to provide a load support arrangement which provides an infinitely adjustable support arrangement which is of high security but at the same time is nevertheless adapted to the economic needs of lighter storage.
- According to the invention, a support arrangement comprises an upright having a pair oppositely extending flanges along its longitudinal length, a pair of elongate elements connected together to form a cantilever arm and provided with recesses engageable with the flanges on opposite sides of the upright and means for advancing the recesses towards each other such that the upright is gripped between the two elements, the recesses being shaped to bite into the flanges of the upright when the recesses are advanced towards each other, and means for engagement with the upright so as to cause the cantilever arm to take up an approximately horizontal position when assembled.
- Preferably, the recesses have a substantially "V"-shape, the width of the "V" at the open end being larger than the thickness of the flange of the upright and the thickness of the "V" at its other end being less than the thickness of the flange, whereby a biting action of the recess on the flanges of the upright is achieved when the recesses are advanced towards each other.
- The means for holding the cantilever arm approximately horizontal may comprise a second pair of recesses, one recess on each element, which engage the flanges of the upright at a spacing from the first recesses. The second recesses may, if desired, be also of a shape to bite into the flange, but this is not essential.
- In a preferred embodiment of the invention, the upright comprises an "I" beam, the flanges of which are provided for attachment of the cantilever arm. The cantilever arm suitably comprises a pair of U-section longitudinal elements connected together at one end and being provided at the other end with a pair of U-shaped brackets, the arms of the brackets being cut to form a pair of V-shaped recesses and the brackets being orientated so that the recesses engage the flanges of the "I" beam. The U-shaped elements are suitably connected, adjacent the recess carrying elements, by means of a nut and bolt arrangement whereby the spacing between the elements can be reduced to advance recesses on to the flanges of the upright so that they bite into the upright and provide a high security for the cantilever arm.
- The invention will now be described in greater detail, by way of example, with reference to the drawings, in which:- .
- Figure 1 is a perspective view of one form of support arrangement in accordance with the invention;
- Figure 2 is an enlarged plan view of the arrangement of Figure 1, and
- Figure 3 is an enlarged perspective view of the attachment part of the arm.
- Referring particularly to Figure 1, there is shown a perspective view of a load arrangement in accordance with the invention. This comprises an "I" section upright 1 which is supported on a base member, which may be a similar "I" beam extending horizontally at the bottom of the beam 1 and not shown here.
- A
steel cantilever arm 3 is supported on this "I" section upright 1 (suitably a rolled steel beam) by means of the twoflanges 4 and 5 which are adjacent to each other and provide guide elements for thecantilever arm 3. - The
cantilever arm 3 suitably comprises twoarm elements arm elements bolt arrangement 10. - At the upright end, each
arm element bracket members arm element - As can be seen particularly from Figure 3, these U-shaped
bracket members rectangular base portion 14 and two upstanding substantiallytriangular members shaped recess 18 therein into each of which aflange 4 or 5 is to seat. (Figure 2). The twoarm elements bolt arrangement 20. - As can be seen from Figure 2, the dimensions of the V-
shaped recesses 18 are such that they have wider mouths than the width of theappropriate flange 4 or 5 but they narrow as they proceed inwardly to a dimension in which they are narrower than the width of theflange 4 or 5. Thus, when the opposing pairs ofbrackets flanges 4 and 5 of the I beam, the sides of each V-shaped recesses 18 will bite into aflange 4 or 5 and thus secure thearm 3 in place. Additionally to this gripping feature, due to the fact that there are two V-shaped recesses in each bracket, spaced apart vertically of the upright, the weight of thecantilever arm 3 and any load which is placed thereon will cause a skewing of thebrackets upper V slot 18 and the front slope of the lower V-shaped slots 18 with theflanges 4 and 5 will be increased, thus providing initial location of thecantilever arm 3 as will be described hereafter. The operation of assembling a cantilever arm to an upright will now be described: - With the upright 1 located in the correct position, i the nut and
bolt arrangement 20 is removed from the arm and the nut andbolt 10 is located to allow the necessary parting of thearms flanges 4 and 5 are seated in the V-shaped grooves 18. With the arrangement held in position in this way, the nut andbolt arrangement 20 is threaded through the appropriate apertures in thearms 7 and 8 (and thebrackets 11 and 12) and is finger tightened to initially hold thearms bolt arrangement 10 may also be tightened. With the arrangement in this position, thearm 3 may be moved up and down the upright 1 for final adjustment to the correct position. When it has arrived in its correct position, thearm 3 will be located here by the action of the weight of the arm acting to skew thebrackets bolt 20 thoroughly so as to force theflanges 4 and 5 hard into thegrooves 18, the sides of thegrooves 18 biting into the ends of theflanges 4 and 5 and providing a lock for the cantilever arm of high security. The nut andbolt arrangement 10 can be tightened at this time if it has not been carried out previously. - It will be appreciated that various modifications may be made to the above described embodiment, without departing from the scope of the invention. For example, if desired one or other of the V-shaped slots may be replaced by a rectangular slot or even by an appropriately located edge, one V-shape slot being sufficient for securing the arm to the upright in most cases, the other slot or surface being required purely to maintain the orientation of the arm in a substantially horizontal position and also to provide initial location of the arm on the upright before tightening procedures have been carried out. Furthermore while a V-shaped slot has been proposed, it is not essential that the base of the V be pointed providing that suit- able slanting of the sides is achieved. In certain circumstances, this slanting of the sides could be used even with a curve rather than straight edge to the "V".
- While the brackets have been indicated as being welded to the arm elements, they may of course be fixed by other means such as nuts and bolts or rivets. The sloping slides of the
brackets shape slot 18 are not essential and could be replaced by straight edges parallel to theelements arm elements elements bolt 10, by means of a hinge arrangement so that assembly of the beam on the upright is somewhat simplified. While the material is proposed for the construction, have been described as been steel, any other suitable material could be used, provided that the dimensions and the relative hardnesses of the materials of the upright support and theU-shaped elements members - It will be noted that while it is the intention to provide a substantially horizontal cantilever arm, it is usual to provide an upward inclination of the arm so that it becomes horizontal under load. If the arm then drops below the horizontal, the arm is overloaded.
