专利说明:
[0001] The present invention relates to an adjustment device, particularly for adjusting the levelness of a surface or of an electric appliance, such as for example a set of burners of a cooker for watercraft. [0001]
[0002] Currently, in the nautical sector it is known to provide fittings which use surfaces or electric appliances which must be arranged in a horizontal position in order to be used correctly. [0002]
[0003] This aspect clashes with the fact that during certain types of sailing, for example during close-hauling, the boat remains more or less constantly tilted to one side at a certain angle. [0003]
[0004] This is due to the fact that it is not possible to fully compensate for the presence of crosswind, which increases as one sails closer to the wind, i.e., as one sails upwind. [0004]
[0005] The fact that the vessel has this tilt, which in large vessels such as cruise ships remains constant for long periods, causes the problem that it is not possible to perform all those operations that require the availability of a substantially horizontal surface. [0005]
[0006] One of these cases occurs, for example, for cooking food on sets of burners of cookers for watercraft, which nowadays has been partly remedied by means of conventional devices for compensating for lateral tilting. [0006]
[0007] These devices, which also act as limiters and damping elements for the oscillations caused by the rolling of the vessel, substantially consist of a pair of pivots which are rigidly coupled to, and protrude outward from, for example the opposite lateral panels of the cooker unit that supports the set of burners. [0007]
[0008] The pair of pivots is usually arranged proximate to the upper side of the panels, advantageously proximate to the centerline of the lateral panels of the cooker unit. [0008]
[0009] The two pivots are accommodated in appropriate seats provided for example on two vertical wings which are rigidly coupled to a support which is fixed to the vessel. [0009]
[0010] Such pivots, by being able to rotate freely in the respective seats, allow for example the cooker unit to remain vertical, since the rotation of the watercraft does not affect its position because the contacts between the watercraft and the cooker unit are limited only to the pivots. [0010]
[0011] The main drawback of this device is the fact that the center of gravity of the cooker unit is not fixed in a single position but varies according to the weight and arrangement of the items placed on the surface or on the worktop of the electric appliance. [0011]
[0012] A frequent drawback occurs, for example, when one rests a pot or heavy container close to the front or rear edge of a set of burners of a cooker unit for nautical use. [0012]
[0013] Such additional weight, if it is not negligible with respect to the weight of the surface or of an electric appliance and if it lies outside of the axis traced by the line that joins the two pivots, shifts the overall center of gravity and therefore may cause the content of the pot to spill. [0013]
[0014] A similar problem arises when one has to open the oven door: due to its own weight, the door may cause the rotation of the cooker unit and may cause a small pot placed on the burners to move and fall. [0014] SUMMARY OF THE INVENTION
[0015] The aim of the present invention is to solve the above-noted problems, eliminating the drawbacks of the cited prior art, by providing a device which allows to use, in a watercraft, a supporting or cooking surface which can remain level even when the weights arranged on it vary. [0015]
[0016] Within the scope of this aim, an important object of the present invention is to provide a device in which its levelness can be achieved rapidly and easily by the user as the weights arranged thereon vary. [0016]
[0017] Another important object is to provide a device which does not require particular tools for its activation. [0017]
[0018] Another object is to provide a device which is structurally simple and has low manufacturing costs. [0018]
[0019] This aim and these and other objects which will become better apparent hereinafter are achieved by an adjustment device, particularly for adjusting the levelness of a surface or of an electric appliance having two side panels provided with two pivots for pivoting to a fixed support, characterized in that said pair of pivots is slidingly located in a longitudinal seat and interacts with position-varying means which can be activated by the user.

[0031] With reference to the figures, the reference numeral [0031] 1 designates a cooker unit for watercraft, which is constituted by a cooking oven 2 above which a set of burners designated by the reference numeral 3 is provided.
[0032] The cooker unit [0032] 1 is provided with two side panels, designated by the reference numerals 4 a and 4 b, which have a pair of respective pivots 5 a and 5 b for pivoting to a fixed support which is advantageously constituted by two vertical elements which are generally designated by the reference numeral 6.
[0033] The cooker unit [0033] 1, by being in contact with the watercraft only at pivots 5 a and 5 b, is thus rotatably coupled to the fixed vertical elements 6.
[0034] Proximate to upper sides [0034] 7 a and 7 b of the side panels 4 a and 4 b there is a levelness adjustment device which is constituted by a pair of mechanisms, designated by the reference numeral 8 a and 8 b and each conveniently arranged at the respective upper side 7 a and 7 b.
[0035] Of mechanisms [0035] 8 a and 8 b, which are mutually mirror-symmetrical with respect to a vertical plane, only mechanism 8 b is described hereafter, mechanism 8 a being exactly the same with the same element.
[0036] The mechanism [0036] 8 b is advantageously constituted by appropriate means, for example a knob, designated by the reference numeral 9 b, which are adapted to vary the position of the pivots and therefore of the cooker unit 1 with respect to the fixed vertical elements 6.
[0037] The knob [0037] 9 b protrudes rotatably from the front surface, designated by the reference numeral 10 b, of the side panel 4 b, at a first hole 11 b.
[0038] A first end [0038] 12 b of a threaded bar, designated by the reference numeral 13 b, is rigidly coupled to the knob 9 b at its axis directed toward the inside of the cooker unit.
[0039] The threaded bar [0039] 13 b is conveniently arranged at right angles to said front surface 10 b and is screwed at a second end 14 b to a wing of a bracket, designated by the reference numeral 15 b, which has a box-like shape.
[0040] The bracket [0040] 15 b, which is advantageously made of metal, accordingly has a first flat surface 16 b, a second flat surface 17 b, and a third flat surface 18 b which have a rectangular plan shape and are arranged at right angles to each other.
[0041] The first surface [0041] 16 b, arranged at right angles to the threaded bar 13 b, has a second hole 19 b which is threaded complementarily to the threaded bar for rotary connection to the bar.
[0042] The second surface [0042] 17 b is advantageously arranged parallel to the side panel 4 b.
[0043] The pivot [0043] 5 b is rigidly coupled to the second surface 17 b, advantageously by means of a mechanical connection, for example by means of a screw designated by the reference numeral 20 b; the pivot 5 b conveniently protrudes outward through an appropriately provided slot 21 b which is formed in the side panel 4 b and is advantageously arranged in a horizontal position, thus acting as a guide for the sliding of the pivot 5 b.
[0044] The height of the slot [0044] 21 b is advantageously smaller than the diameter of the pivot 5 b, so as to prevent movements thereof along its axis.
[0045] The third surface [0045] 18 b, which is arranged horizontally and is connected, in a downward region, to said first and second surfaces, is adapted to rest against an upper fourth surface which is optionally constituted by the upper edge 22 b of the side panel 4 b.
[0046] FIGS. 12 and 13 illustrate the optional presence of means for selectively locking the position of the knob [0046] 9 b which are advantageously constituted by a knurled ring 23 b which is screwed onto the first end 12 b of the threaded bar 13 b, in an intermediate position between the knob 9 b and the front surface 10 b.
[0047] FIGS. 14, 15 and [0047] 16 illustrate a second type of means for selectively locking the knob 9 b which are constituted by an eccentric pivot, designated by the reference numeral 24 b, which can move axially and has a head 25 b and a stem 26 b.
[0048] The eccentric pivot [0048] 24 b is adapted to temporarily engage, at the stem 26 b, a suitable complementarily shaped seat 27 b which is formed at the front surface 10 b.
[0049] The position-varying means can optionally consist, as an alternative to the knobs, of at least one electric motor whose motor shaft is advantageously but not exclusively coaxial to the respective threaded bar, which is connected thereto by way of first transmission means, for example mechanical gears, which are adapted to transmit the rotary motion. [0049]
[0050] The at least one electric motor, which can be advantageously operated by the user, can in turn be associable, by way of second transmission means, for example transmission belts and mechanical gears, with the threaded bar arranged at the opposite side panel, so as to actuate the simultaneous movement of both of said threaded bars. [0050]
[0051] Operation is therefore as follows. With reference to FIG. 1, the user can, depending on whether the door of the oven [0051] 2 is opened or on the particular arrangement of items on the set of burners 3, simultaneously turn the two knobs 9 b clockwise or counterclockwise, so as to be able to reduce or eliminate the inclination assumed by the cooker unit 1.
[0052] By turning the optionally provided knurled rings until they rest against the respective front surfaces, it is possible to lock the knobs [0052] 9 b, so as to avoid accidental rotations thereof due for example to unintended contacts.
[0053] The rotation thus imparted to the two threaded bars [0053] 13 b associated with the knobs 9 b in fact causes the translatory motion of the respective brackets and of the pivots rigidly coupled thereto in the intended direction, thus returning the center of gravity of the cooker unit 1 to the vicinity of the vertical plane that passes between the two pivots 5 a and 5 b.
[0054] As an alternative to this locking method, it is possible to provide an eccentric pivot, arranged on the knob [0054] 9 b, which by sliding axially can lock in an appropriately provided seat formed in the respective lateral surface.
[0055] The head of the eccentric element, which is optionally knurled in order to facilitate its grip, can also facilitate the rotation of the knob [0055] 9 b if it is a crank.
[0056] It has thus been observed that the invention has achieved the intended aim and objects, a device having been provided which allows to use, in a watercraft, a surface or an electric appliance which remains level even when the weights placed on it vary. [0056]
[0057] The materials employed, as well as the dimensions that constitute the individual components of the invention, may of course be more pertinent according to specific requirements. [0057]
