Definitions
- the invention relates to a hinge for constraining a door to a support structure.
- the invention concerns a hinge which can be used to constrain the doors of electrical domestic appliances such as ovens, to the support structure of the appliances.
- Hinges of this type are usually constituted by two distinct and stably and kinematically connectable parts. Each part comprises a box structure having a more or less vertical development.
- the two box structures are rigidly fixable to the support structure, which in this case is the oven itself, and to the door near to its lower edge so that the door is tiltingly openable.
- a lever is pivoted to the part of the hinge solid to the door, more specifically to the box structure constituting it.
- the pivot about which the lever is hinged to the box structure coincides with the rotation axis between the door and the oven structure.
- the lever is removably constrainable to the lower end of a longitudinal slot made in the other part of the hinge, that is in the other box structure which is fixed to the oven.
- the end of the lever exiting from the box structure it is pivoted to is destined to be rigidly associated with the other box support structure, fixed to the oven, and it exits from a respective longitudinal slot in the box structure itself.
- the lever is arranged close to an end of the box structure to which it is pivoted, and the extreme transversal edges of the slot act as end-run stops for the lever.
- the longitudinal wall of the box structure comprising the slot acts as an end-run stop for the lever in its closed-door configuration, and the nearby transversal wall, which usually delimits the slot, acts as an end-run stop for the lever in its open-door configuration.
- Elastic means act on the lever, interposed between the lever and the box structure of the part of hinge associated to the door. More precisely, the elastic means operate between the box structure and a rod internal to it. The rod is free to move along the box structure containing it and is pivoted at its free end, that is with its end that does not interact with the elastic means, to the lever. The fulcrum between the rod and the lever is situated in a zone of the lever which is interposed between the fulcrum of the lever and the box structure containing it and its end which is constrained to the other box structure, fixed to the door.
- the elastic means contrast both the first distancing of the door from the oven structure, and the successive rotation of door and its consequent lowering into a totally-open-door configuration.
- this type of hinge continually exerts a force on the door which tends to keep them in their closed-door configuration.
- the hinge conformation and the arrangement and calibration of the elastic means are such as to permit of considerable reaction to the opening of the totally-closed door since they have to guarantee the total closure of the door during use of the oven at all temperatures, when considerable pressures are created inside.
- the spring is connected at one end to the door and at the other end to a lever that is pivotally connected at the chassis of domestic appliance.
- the spring that was initially stretched, moves the door to the ajar position. In this position the spring has the minimum length and therefore the door is in a stable position.
- the aim of the present invention is therefore to provide a hinge of the above-mentioned type able to permit a first door-opening which is practically automatic with a subsequent opening on the application of a force that gradually diminishes up until it reaches a condition of substantial equilibrium with the couple exerted on the door by its own weight, which, in the meantime, is economical and easy to make and mount.
- the invention resolves the problem of constraining a door to a support structure by providing a hinged comprising :
- a hinged unit according to the present invention is characterised respectively by the features of the characterising part of independent claims 1 and 2.
- 1 denotes an oven, comprising a containing structure 2 at which front lower zone a door 3 is connected by means of two hinges 4 permitting the door's rotation in the two directions about a common horizontal hinge axis 5 (figures 2 and 3).
- the containing structure hereinafter known as the support structure 2
- the hinges 4 shall be considered in connection with an oven.
- the hinges 4 are located close to the lower horizontal edge 3' of the door 3 so that the door 3 can be opened by tilting.
- the hinge 4 is of the type made in two separate parts which are easily connectable to each other both kinematically and rigidly, as will emerge from the following description.
- the two parts composing the hinge 4 comprise a first part 6 which is fixed to the support structure 2 and a second part 7 which is fixed to the door 3.
- the first part 6 comprises a first box structure 6' and the second a second box structure 7', a lever 8, a rod 9 and elastic means 10.
- the lever 8 is kinematicallly connected internally to the box structure at one of its ends and is easily and rapidly rigidly constainable to the first box structure 6', with its second end projecting from a vertical slot 11 in the box structure 7'.
- the rod 9 is arranged longitudinally internally to the box structure 7' and is kinematically connected, at one end and by means of a pivot 12 parallel to the lower edge 3' of the door 3, to an intermediate point in the lever 8.
- the elastic means 10 act on the other end of the rod 9 and preferably comprise a helix spring working by compression.
- the spring 10 is keyed on the rod 9 externally to the box structure 7', and is held between a plane 36 forming the top of the box structure 7' and a stop constituted for example by a first crossbar 13 inserted by force through a seat 37 made on the free upper end of the rod 9.
- the hinges 4 are arranged with their respective hinge axes 5 horizontal and coinciding, and are normally applied at the lower portion of the door 3, which door 3 is then mobile between a horizontal position (open) and a vertical position (closed).
- Figure 4 shows the rod 9 is made in two consecutive portions 15 and 16, the first 15 of which is hinged to the lever 8 and exhibits a wide U-shaped transversal section.
- the second 16 is also U-shaped but has a narrow transversal section and will couple inside the U-section of the first portion 15.
- the first portion 15 has, at its end which couples with the other portion 16, a second crossbar 17 which is inserted by force along a seat 18 made in the end of the first portion 15 and which is hooked by a hook 42 equipping the second portion 16 to form a stable coupling.
- the second portion 16 projects from the box structure 7' through a correspondingly shaped hole 19 made on the same plane 36.
- the second portion 16 is inserted into the spring 10, up until the spring 10 strikes against the first crossbar 13, and then the assembly is inserted into the corresponding hole 19 in the plane 36 of the box structure 7'; then, by compressing the spring 10, the second portion 16 is inserted into the wider portion 15 so that the seat 18 engages the second crossbar 17.
- FIGS 2 and 3 show that the lever 8 is pivoted directly at the box structure 7' by means of the pivot 12, and the rod 9 is hinged directly to the lever 8 by a pivot 20 parallel to the other pivot 12.
- the pivot 20 and the pivot 12 do not move during the door 3 rotation and therefore also during the rotation of the second part 7 of the hinge 4 with respect to the lever 8, which is associated to the first box structure 6' by means of a seating 8' which strikes an internal stop 14 of the structure 6' and with its free end a pin 35, both the internal stop 14 and the pin 35 being arranged on the first box structure 6'.
- the second box structure 7' rotates about a first axis 5 of the pivot 12 while the rod 9 rotates about a second axis 24 of the pivot 20.
- the axis 5 is also the rotation axis of the second part 7 of the hinge 4 and thus also of the door 3 with respect to the support structure 2.
- the second axis 24 and therefore the pivot 20 are above the first rotation axis 5 and are relatively fixed.
- the means 21, denotes, in figures 1, 2 and 3, a rapid door blocking-unblocking means in an open and closed configuration.
- the hinge 4 in both the two preferred embodiments, illustrated in figures 2, 3 and 4, comprises the spring 10, which acts dynamically between the two parts 6 and 7 composing the hinge 4.
- the pivot 20 and the fulcrum axis 24 between the rod 9 and the lever 8 is arranged further away from the first part 6 with respect to the pivot 12 and thus the rotation axis 5.
- the axis 24 is arranged on the opposite side of the first box structure 6' to the first axis 5.
- the hinges 4 determine a first rapid rotation of the door 3, about the said common hinge axis 5, and thus a progressive but slower opening, up until total open position is reached.
- the slowed opening occurs under the effect of the combined action of the weight of the door 3, which favours the opening movement, and a braking action exerted by the hinge 4 on the door 3.
- the elastic force which the spring 10 generates between the rod 9 and the box structure 7' acts according to a first resultant R1 passing along a direction indicated in figure 2, with D1 passing through the second axis 24.
- the first rapid opening phase of the door 3 occurs since the pivot 20 and the axis 24 are arranged in the above-mentioned way with respect to the pivot 12, and the resultant R1 of the force exerted by the spring 10 on the pivot 12 through the rod 9 lies, at the extreme closed position of the door 3, externally to the first rotation axis 5 and is therefore such as to determine the application of a clockwise-direction first moment (denoted for clarity in figure 2 by M1) on the second box structure 7', producing the opening of the door 3.
- M1 clockwise-direction first moment
- the elastic means 10 is split and comprises further springs 30.
- a lateral wall 26 of the second box structure 7' internally supports a tab 27, normal to it.
- the tab 27 is crossed by a hole 28 developing parallel to the longitudinal development direction of the box structure 7'.
- a stem 29 is housed axially slidable in the hole 28 and is coaxial to it.
- a helix spring 30 is wound about the stem 29 in a zone comprised between the tab 27 and the lever 8, which spring 30 is precompressed and exerts on the elements axially contrasting it a greater force than that exerted by the said spring 10.
- One end of the stem 29, adjacent to the lever 8, supports an idle roller 31 with a rotation axis parallel to the pivots 12 and 20.
- the idle roller 31 as will be described in more detail hereinbelow, when the door 3 is closed or just open (within a predetermined limit), rests against a cam 32 made on an upper edge 8'' of the lever 8, while when the door 3 is open further than the said predetermined limit the idle roller 31 detaches from the lever 8.
- the idle roller 31 is supported idly by means of a pivot 40 crossing the portion of stem 29 end and with its opposite ends runs along a slot 41 made in the said second box structure 7'.
- the slot 41 limits the excursion of the said roller 31, as will be described hereinbelow.
- the cam 32 is made on the upper edge 8'' of the lever 8 and develops when the box structure 7' is in its closed configuration (see figure 3), incliningly towards the inside of the structure 7', towards the opening direction of the door 3.
- the pivot 20 and therefore the second rotation axis 24 between the rod 9 and the lever 8 are arranged closer to the first part 6 with respect to the pivot 12 and therefore rotation axis 5.
- the axis 24 is arranged between the rotation axis 5 and the first box structure 6'.
- the second resultant R2 always lies, throughout the entire rotation of the door 3 between the two extreme positions, internally to the first rotation axis 5 and is therefore such as to determine the application of a second moment to the second box structure 7', indicated for clarity in figure 3 with M2, acting in an anticlockwise direction to force the door 3 into its position of closure.
- the functioning of the hinge 4 is also in this case similar to the above-described, since after manually activating the blocking-unblocking means 21 so that there is no impediment to the door 3 opening, the hinge determines at first a small but relatively rapid rotation of the door 3 in the opening direction, about the said common hinge axis 5, and then a slower progressive opening action, up until total opening is achieved.
- the initial phase of rapid opening occurs thanks to the prevalence of the force exerted by the spring 30 with repect to that exerted by the spring 10 on the elements that contrast the ends, and finishes when the roller 31 detaches from the cam 32 of the lever 8, that is, when the position indicated by 33 in figure 3 is reached.
- the spring 30 determines a third resultant R3 on the hinge 4 which generates a third moment M3, clockwise in direction, as indicated in figure 3, which when added to the moment generated by the second resultant R2 results in the first moment M1 applied to the second part 7 of the hinge 4.
- This braking action is due to the fact that, thanks to the described positoin of the pivots 12 and 20, the force exerted by the spring 10 on the pivot 12 through the rod 9 is such to determine the application of a moment to the box structure 7' having a direction that obstructs the opening of the door 3.
- the end portion of the lever 8 has, at the upper part of its end portion destined to be inserted into the first box structure 6', a slot 34 engagable by a fixed pivot 35 parallel to the pivots 12 and 20 and located internally to the first structure itself, and a vertical striker edge 48 interposed between the pivots 20 and 35 and turned towards the pivot 35 itself, able to rest, during the course of the connection of the door 3 to the oven 1, against the said internal stop 14 which, as can be seen in the figures, is constituted by a vertical projection connected to a lower edge of an entry slot 47 for the lever 8 into the support structure 2.
- the lever 8 is stable in the position where it is anchored to the support structure 2, in both extreme door 3 configurations.
- the lever 8 is able in this way to react statically to both reactions that are created on it by effect of the two moments M1 and -M1.
