:'. , BACKGROUND OF THE INVENTION
. ,:
1. Field of the Invention __________________________ :
Palletised goods which are to be stored in a throughrun shelf store installation are usually placed onto rolling supports.
In this way the stored pallets can roll from the input side of a shelf compartment towards the removal side, be it from its own force as a result of a gradient of the shelf itself, or be it under the action of transportation members. When a loaded pallet, together with its rolling support, has been removed from the shelf compartment and has been set down some-where, the necessity can arise of shifting this pallet, re-placing it or moving it in some other way. If it is a que-stion only of a short movement path, the use of mechanical aids is often inexpedient. On the other hand, loaded pallets often have a great weight, up to 1000 kp, so that an operator can, with great exertion, possibly shift a loaded rolling support in a straight line. Since the rolling supports, how-ever, have no steerable rollers, displacement along a curved path only with muscle power is not possible without further aids.

2. Description of the Prior Art ___________ _____________________ , For this purpose, i.e. for the manual manoeuvering of heavily-laden rolling supports, it has already been proposed to use so-called lever rollers. These consist substantially of a long ' ~ .

.
. .

' . -lever arm and a short lever arm which extend at an angle to one another. A pair of rollers is situated at the junction of the two lever arms. The short lever arm is engaged under -the rolling support and can be raised somewhat, so that the support can be moved relatively easily along a curve.
'7 -~
However, these known lever rollers fail completely in the `
cases where the free space under the rolling support is very -slight, since then either engagement there under of the rolling ,. . . .
support is not at all possible, or the lever arm ratio is un-favourable, so that a heavy pallet can no longer be lifted.
A further disadvantage of the known lever rollers is to be seen in the fact that often the raised rolling support can un- ~-intentionally slide down from the lever roller, which can pos- ;
sibly lead to slippage or even to collapse of the load. More-over, these known forms of apparatus involve a not inconsider-able risk of accident, since they are unstable, i.e. when the lever arm is let go they whip upwards and, moreover, when not required for use they are inconvenient to stow away.

OBJECT OF THE INVENTION

The object of the present invention is to preclude all these dis-advantages and to provide transportation apparatus for palletised goods which is particularly suitable for use in connection with rolling supports having only slight underneath free space, which . .
.

~0671~8 supports are nowadays increasingly wide-spread.
SUMMARY OF THE INVENTION -The storage and transport unit in accordance with the lnvention for palletised goods comprises a rolling support which has substantially a rectangular frame provided wlth four rollers, as well as a drawbar ~ `
which is provided with rollers and which can be coupled up -to the ~r, t;~l~.? rolling support. This transportatlon apparatus is characterised in that two opposlte frame 10 sides of the rolling support are formed by an inverted `
U-section having limbs of unequal length, and in that the ~
drawbar has a coupling member which is substantially cubic in shape and which is provided with a groove for receptlon of the shorter limb~f the U-section and which ;~
is mounted so as to be swingable about an axis extending perpendicular to the axis of rotation of the drawbar rollers.
Stated in other words, the invention relates to a mobile-~s~orage and, transport unit for use in a shelf storage system comprising a first part comprising a four sided frame supported with two pairs of rotatable supports disposed at opposite sides respectively of the frame, a second part comprising a drawbar provided with a pair of rollers and adapted to be coupled to said four sided frame of said first part, the frame of said first part comprising two pairs of longitudinal struts and two cross members rigidly connected to form a four sided right-angled frame, the respectlve rotatable supports being disposed between the respective pairs of said longitudinal struts, said two cross members being formed by an inverted U-section having limbs of unequal length~ said second part compri-sing a coupling member which is substantially cubic in -4 ~

lV67118 : ~
shape ~nd which is provided with a groove for reception j~
of said shorter limb of said U-section, said coupling mem-~ -ber belng pivotably mounted on said drawbar about an axis extending perpendicular to the axis Of rotation of said pair of rollers.
BRIEF DESCRIPTION OF THE DRAWINGS

.
Initially reference is made to Figs. 1 and 2. The unit com-prises a rolling support which has two transverse traverses -1 and 2 connected together by two pairs of longitudinal struts 3a, 3b and 4a, 4b. It can be appreciated from Fig. 2 that the longitudinal struts are set in somewhat relative to the ends of the transverse traverses 1 and 2. The longitudinal struts respectively of each pair are arranged side-by-side at a small spacing apart and serve for the mounting of respective rollers 5, which are rotatably mounted by respective axles 6. The longi-tudinal struts 3a, 3b, 4a, 4b can be simple square hollow sec-tions which are welded at their ends to the transverse traverses 1 and 2.

~ 67118 - 6 - ~

The shape of the two transverse traverses 1 and 2 can be seen ~ -from Fig. 3. They are substantially invertedly-arranged U- ~
sections each having a shorter limb 8 and a longer limb 7. `
The longer limb 7 is connected to the longitudinal struts 3 and 4, while the short limb 8 lies at the other end of base ~
9 of the section. Situated at the free end of the longer limb -7 is an extension 10 which protrudes perpendicularly towards `
the interior of the U-section. The shorter limb 8 forms, with ~ `
the base 9 of the U-section, an angle which is less then 90, preferably about 70 to 80.

The construction of the drawbar can be seen from Figs. 4 and 5.
Fastened to a supporting tube 11 is a manoeuvring lever 12 which has a length of about 100 to 120 cm. The supporting tube 11 re-ceives a shaft 13 at each end of which is a rotatable roller ~
14. Moreover, a shaft journal 15 is fastened in such a way to ~ `
the supporting tube 11 that is forms a right angle with the rotational axis of the rollers 14, and that it forms an angle of about 60 with the manoeuvering lever 12. This shaft jour-nal 15 can, for example, be welded securely to the supporting tube 11 and serves for the reception of a coupling piece 16.
The latter has a substantially cubic shape and is mounted so as to be rotary on the shaft journal 15. The external dimensions of the coupling piece 16 correspond approximately to the clear inside cross-section of the cross traverses 1 and 2.

- ,.

- ~Q67~18 ~ ~

The upper edge of the coupling piece 16, which is turned to the manoeuvering lever 12, is bevelled and provided with a groove 17. The swivel axis of the coupling piece 16 on the shaft journal 15 also extends through this groove 17. The ;~
groove 17 is intended for the reception of the shorter limb 8 of one or the other of the cross traverses 1 and 2, as will be described in yet more detail later on.

The edge of the coupling piece 16 which lies diametrically opposite the aforesaid edge, i.e. that lower edge of the coupling piece which is averted from the manoeuvering handle, is bevelled to form a bearing surface 18. This surface 18 lies in plane T which is tangential to the rollers 14 of the draw-bar. The direction of this bevelling 18 is immediately clear ~rom Fig. 6 from which it will be seen that in the set-down state of the drawbar, said drawbar is supported by the bevel 18 and thus assumes a stable disposition.

Fig. 7 shows the rolling support resting with its rollers 5 on the floor 19, this support being required to be moved in-to a different position. For this purpose, the drawbar descri-bed in the foregoing is brought into the position, evident in Fig. 7, in which it is disposed under one of the cross tra-verses, in the present example under the cross traverse 1. The disposition of the drawbar, ready for coupling to the rolling support corresponds approximately to the set down position, shown in Fig. 6S of the drawbar. It should be pointed out that .
: .

- . -:

during attachment of the drawbar the manoeuvering lever 12 assumes a substantially vertical position and thus its manipu- ~-lation is not hindered by any load built up on the rolling support. The short titled limb 8 of the U-section 1 is posi-tioned directly over the groove 17 in the coupling piece 16. ` `
Thereupon, the manoeuvering lever 12 is swung in the direction of the arrow P, until the position shown in Fig. 8 is reached.
It can clearly be seen how, as a result, the coupling piece 16 engages into the interior of the U-section 1, and the shorter limb 8 enters into the groove 17 and is located therein in -~
self-locking manner as a result of its obliquity.
'',`' ' ' As soon as the position of Fig. 8 is reached, the rolling sup-port can be manoeuvred virtually effortlessly. Because of the wingable mounting of the coupling piece 16, travel around very tight curves is possible, providing for simple manoeuvrability of the loaded rolling support even in the narrowest spaces.
Slipping-down of the rolling support from the drawbar is not possible, since the design of the groove 17, with its bevelled side wall, is such as to hold the correspondingly bevelled limb 8 of the U-section 1 all the more securely the greater the tractive force on the drawbar. By appropriate selection of the lever arm ratio, the result can be achieved that the pressure which is exerted in the vertical direction on the coupling piece, and which is reflected in a torque at the axis 13 of the rollers 14, is compensated for by the torque which is exerted .

vantageously there can be mounted at the free end of the ma- ;
noeuvring lever 12, a handle (not shown) which extends perpen-dicularly thereto and which can possible be provided with a weight for the additional compensation of the torque which :
is exerted by the laden rolling support. ~ -, . ~ ... ..
