Definitions

  • shelf support should be construed in a broad way, to include any device comprising a shelf (or a similar means), e.g. a cupboard.
  • Devices of this type are used to lower shelves and cupboards form a position high up on a wall to a position lower down in order to facilitate access to articles placed high up, which fulfils a big need, especially for disabled persons.
  • a typical area of application is the raising and lowering of shelves in an overhead cupboard in a kitchen.
  • These raising and lowering devices are set to guide the cupboard/shelves along a fixed path, which in the case of the rail-guided devices is a straight line, whereas it is a circular arc in the case of the devices which make use of arms of parallelogram configuration.
  • the path which the cupboard/shelves follow is fixed once and for all when the device is installed.
  • the raising and lowering devices which function with the aid of arms of parallelogram configuration, have arms consisting of several links, which inevitably results in a certain slack and above all the danger of the arms "scissoring" the wrong way when the arms assume a position parallel to or almost parallel to one another.
  • a second problem with the parallelogram mechanism is that when the sides (the arms) of the parallelogram approach one another a great moment of force is exerted on the drive mechanism.
  • the drive mechanism must therefore be dimensioned so as to be very strong or, alternatively, the moment of force must be compensated by means of weights or springs. Since the moment of force varies greatly depending upon the weight of the shelves, the weight or springs will not be able to compensate satisfactorily.
  • WO 97/00631 there is known a shelves support and device, which solves the above problems.
  • this known device does present some disadvantages.
  • a major problem is its expensive design. Despite its supreme functionality in comparison with existing prior art devices, it has been difficult to get it onto the market due to its high cost.
  • a further disadvantage is that the device according to WO 97/00631 uses an endless device, e.g. an endless chain, for transmitting rotational movement. Firstly, this is a rather expensive solution. Secondly it might be difficult to adjust the length of such an endless device. Thirdly it controls rotational movement in both directions, which possibly might cause injures, since there is no releasing mechanism that could disengage the force that is mechanically transmitted by the endless device.
  • Fig. 1 there is shown a first embodiment of a device according to the invention, in a side view.
  • a shelf support 2 which supports a number of shelves 3.
  • a preferred application would be a shelf support 2 forming a part of a kitchen cupboard positioned above the kitchen counter.
  • a bracket device 40 On the back of the shelf support 2 there is fixedly attached a bracket device 40, which can be seen as a rotating device 16.
  • the bracket 40 is preferably attached to the cupboard by means of screws or similar attachment means (not shown).
  • the bracket 40 comprises an arcuate portion 41 at the upper end thereof.
  • the arcuate portion 41 has a surface 42 which is displaced along a radius R 1 .
  • the bracket 40 is connected to an arm 1 by means of a shaft 5.
  • the shaft 5 is preferably a separate part but may also be a stub shaft integrated with the arm 1 or the bracket 40.
  • the arm 1 and the bracket 40 may pivot in relation to each other about the shaft 5.
  • the arm 1 is pivotally attached to a second a shaft 6, which is positioned within a second bracket 50, which may be seen as load transmitting device 13.
  • the second bracket 50 is fixedly attached to a base portion 9, which is attached to a wall (or similar) by means of appropriate attachment means, e.g. screws.
  • the second bracket 50 may be integral with the base portion 9.
  • the second bracket 50 comprises an arcuate portion 51 which is positioned at its upper portion and which has a surface 52 being displaced along a constant radius R 2 .
  • R 1 is the same as R 2 , as will be explained further below.
  • a flexible rotation transmitting device 14 e.g. a steel cable, a chain or the like.
  • the rotation transmitting device 14 e.g. cable
  • the flexible device 14 is adjustably attached to the second bracket 50, preferably by means of a threaded bore 58 and a screw 59 which is attached to the outer end of the flexible device 14, such that the length of the cable 14 extending between the brackets 40, 50 may be adjusted.
  • a first lifting bracket 34 having a shaft/pin, protruding into a hole 33 at one end of a lifting device 30.
  • a second hole 32 At the upper end of the lifting device 30 there is a second hole 32, which is pivotally arranged about a shaft/pin within a second lifting bracket 31, which is fixedly attached to the upper part of the base portion 9.
  • the lifting device 30 preferably is a kind of an electrically powered thread/gear mechanism, by means of which the arm 1 may be moved up and down.
  • the lifting device 30 may also be in the form of a hydraulic or pneumatic device, or anything else known in the art suitable for lifting and lowering an arm.
  • figs. 2A and fig. 2B there are shown two different positions of a device according to the invention.
  • the device In fig. 2A the device is in its innermost position such that the arm 1 and the shelf support 2 are substantially vertically arranged in a position adjacent the base 9 which is attached to e.g. a wall. It can be seen that the device forms are very compact unit in its innermost position.
  • fig. 2B there is shown a position where the device is in an outer position, but where the arm 1 is slightly above being horizontal.
  • a shaft/pin 32 may be arranged in a hole which is formed in a bracket 9A that is integral with the base 9.
  • fig. 3 there is shown the basically same device as in fig. 1 and figs. 2 but in one position where the arm has been lowered to a position where it is below a horizontal level.
  • the force S2 acting in the cable 14 in the lower position is much larger than it is S1 in an upper position (supposing the same load F exerted by the cupboard 2, 3), because the lever arm A 2 is much smaller in the lower position than it A 1 is in the upper position.
  • This is achieved by positioning the lower axis 6 off-centred in relation to the centre C of the radius R2 of the arcuate surface 52 and displaced a distance L outwardly in relation to the base 9.
  • fig. 4 there is shown a perspective front view of the device shown in figs. 1-3.
  • the base portion 9 is made of a plate like base part 9B having a frame of protruding edges 9C.
  • the arm 1 is made of a plate like base part 1C which at its sides is arranged with reinforcing ribs1A, 1B. Thanks to this design lengthy pivoting attachments are formed for the shaft 5, 6 for the arm 1, which provides for strength and stable movement.
  • the adjustability of the cables 14, which can be made independently one from the other, makes it possible to exactly adjust the path of movement of the device.
  • one and the same size of the device may be used for different sizes of cupboards.
  • fig. 5A there is shown a schematic side view of a preferred embodiment, with an integrated security mechanism, in an unreleased position. It is shown that the arm 1 is divided into a base portion 1D and top portion 1E, which are joined to each other by means of a shaft 60.
  • the top portion 1E may pivot about the shaft 60 in an inward direction, from the position shown in fig. 5A.
  • the top portion 1E cannot pivot in the other direction, since an extension 61 of the base portion 1D extends above the position for the shaft 60, which accordingly forms a limit stop for the top portion 1E.
  • the rotating device 16 is pivotally attached to a shaft 5 at the top of the arm 1, i.e. at the top end of the top portion 1E.
  • the top portion 1E will be urged against the stop limit 61.
  • a locking mechanism to securely hold the top portion 1D against the stop limit 61, especially when the arm is in its innermost position (vertical).
  • Such locking mechanism could comprise an excenter bolt that would move with the lifting device, which bolt could push a locking pin into engagement in a hole.
  • the device function as described above.
  • fig. 5B there is shown a front view of a slightly modified device as shown in fig. 5A. It can be seen that the top portion 1E of the arm 1 is modified and made up of two different pieces 64, 65.
  • One of the pieces 64 is made of rod like device being pivotally attached to the intermediate shaft/axis 60 and with its top end to the upper shaft 5.
  • the other piece 65 which is triangular shaped, has its widest part pivotally attached to the intermediate shaft 60 and its top edge pivotally attached to the outer shaft 5.
  • the cupboard now have the possibility to move around 360° at its lower end. Accordingly, the cupboard may tilt about the shaft 5 more than 180° at the same time as it may pivot about 10 extra shaft 60 180°. Hence, the cupboard has many different possibilities to "move away” in order to eliminate possible squeezing actions or similar.
  • fig. 6A there is shown principally the same as already has been described in figures 5A and 5B.
  • a cupboard 3 being fixedly attached to the bracket 40 which is pivotally attached to top portion 1E of the arm 1.
  • the top portion 1E is pivotally arranged above the bracket 40 by means of the shaft 5, and also in relation to the base portion 1D of the arm about the intermediate shaft 60.
  • the base portion 9 is fixedly attached to a wall.
  • fig. 6A shows that the base portion 1D of the arm is arranged with a cable controlling device 1F. This cable controlling device 1F will assist in controlling the position of the cupboard 3 during a pivoting action about the intermediate shaft 60.
  • Fig. 6B there is shown the same device as in Fig. 6A, but in a released position. It can be seen that the top portion 1E of the arm 1 has pivoted inwardly due to an upwardly directed force having been applied to the cupboard 3. The force is produced due to the cupboard hitting an object 100 on its way down. Thanks to the rotation transmitting device 14 being flexible, the pivoting device 16 and the top portion 1E may pivot about the shaft 60, which consequently also produces a pivoting movement of the shelf support 2/cupboard. Accordingly this mechanism may eliminate possible injuries. It should be noted that the cable controlling device 1F would assist in controlling the movement of the cupboard 3 in relation to the object 100.
  • the cupboard will move along different paths during a continued downward movement of the arm 1.
  • a cable controlling device as shown in fig. 6B
  • a continued rotation of the base portion 1D of the arm will cause the cupboard to tilt inwardly, since the edge of the cable controlling device 1F will exert a pulling action in the cable 14 which moves the upper part of the cupboard 3 inwardly at the same time as the top portion 1E of the arm also provides an inwardly acting force when pivoting about the intermediate shaft 60.
  • the positioning of the cable controlling device 1F can be altered into many different positions, to alter the movement of the cupboard 3 to follow different desired paths.
  • the cupboard 3 would be free to tilt forwardly and/or backwardly, since the cable 14 would then allow such a tilting movement.
  • FIG. 7 there is shown an interlocking device (as described in general terms above), which can lock the top portion 1E of the arm to the base portion 1D of the arm.
  • the interlocking mechanism comprises a first rod 92 which is pivotally attached the lowermost bracket 40 at a position spaced from the shaft 6 for the arm 1.
  • the top end of the first rod 92 is in its turn pivotally attached to a second rod 90, which is movably arranged within a sleeve 91.
  • a female interlocking device 93 which may be penetrated by the movable rod 90 (see the innermost position) such that the arm parts 1D, 1E are secured to each other in a non-pivoting manner.
  • a bracket 50 which also can be seen as the load transmitting device 13.
  • the bracket is preferably made by string casting, such that a regular smooth arcuate surface 52 is formed. Preferably it is also form with longitudinal through holes in order to optimise the use of goods. Further more it is shown that there is a hole 53 for attaching the shaft 6 for the arm 1.
  • the bracket 50 can be adjustably attached to the base portion 9, by means of attaching it with a screw 54 which cooperates with a slot 56 and by means of which the brackets 50 can be somewhat tilted about an attachment shaft 55, e.g. to adjust in relation to irregularities of a wall.
  • Fig. 9 there is shown a schematic view of the same kind of bracket 50 as in Fig. 8, but with a different adjusting mechanism.
  • the adjustment is in the form of a threaded screw 56, which passes through the bracket 50 and cooperates with a threaded bolt 57, fixedly attached to the base portion 9.
  • the bracket 50 may be tilted.
  • Fig. 10 there is shown principally the same as in Fig. 8. However, this cross sectional view also shows the existence of a through hole 58, having a specific configuration, which is intended for cooperation with an adjustment mechanism 59 for adjusting the length of the cable 14. To provide for some resiliency a dish spring 14D may be arranged adjacent the end stop 14C of the cable 14.
  • Fig. 11 there is shown a cross sectional view of a bracket 40 intended for attachment at the top of the arm 1. It is shown that this bracket can also be arranged with a mounting device 47 for attachment of the outer end 14B of the cable 14. Possibly also this end may be arranged with an adjusting mechanism. Further more it is shown that there are arranged three through holes, which are intended for different purposes, i.e. the arm shaft 5 and two holes 48, 49 for fixing the bracket to the shelf support 2. In fig. 12 there is shown the same kind of bracket 40 in a perspective view. It shows that a recess 44 provides space for the lifting mechanism 30 when the device is in its innermost position.
  • the invention is not limited to what is described above but may be varied within the scope of the appended claims.
  • many different kind of materials may be used to produce different details of the device, e.g. aluminium, steel, plastics, etc.
  • many different kind of producing techniques may be used for the different details, e.g. form moulding, string casting, forging, etc.
  • the arm 1 may be divided into two or more parallelly arranged arms.
  • any male/female connection described e.g. the pivoting attachment device of the lifting device 30, may be made one or the other way, i.e. the pin/shaft being attached to the lifting device or the bracket and vice versa.
  • many kind of shafts/pins may be used to arrange for any of the axes described above.
  • the device 92 that provides the locking action for the locking rod 90 may be attached in many different positions (e.g. to the base portion 9) but still providing the same kind of function.
