Description

Technical Field

[0001] The invention relates to a hinge for opening and closing a furniture component with a 45° bevel, in particular a door with a 45° bevel - the door has a 45° bevel like the corresponding part of the furniture body (which can be the side, bottom or top).

[0002] For the sake of convenience, in the following description, the hinge discussed will also be referred to as a 45° door hinge, or simply a 45° hinge. Background Art

[0003] As is known to all, the standards for circulating furniture stipulate that the doors are cut at an angle of 90° and there are a variety of hinges on the market, both exposed and recessed, which allow these doors to move when opening and closing.

[0004] For certain applications, or simply for aesthetic reasons, users prefer doors that are cut at 45° so that the door edge is not exposed when closed.

[0005] However, the movement of these types of doors requires specific hinges which do not always meet the requirements of the user, since they are either complicated to install, they do not have springs to assist closing, or in the closed state they protrude excessively into the compartment of the furniture item, among other things.

[0006] Furthermore, these known hinges usually do not have a damper which acts to cushion the impact of the door on the body of the furniture item when the door is closed, as is currently the case with most hinges for standard doors with a 90° cut.

[0007] US 4817241 A filed in the 1980s describes a 45° door hinge of the type referred to in the present invention. This hinge has a particularly complex structure, with fixed and movable parts having a substantially circular profile and requiring a seat with the same circular profile to be machined in the movable part to be connected. This document is mainly based on providing a gear arrangement to allow adjustment of the fixed and movable parts in mutually perpendicular directions. Neither elastic means for assisting closing nor speed reduction means for slowing down the closing speed are provided. Such means are also not provided in the hinge structure described.

[0008] CN 203640462 U describes a wide-opening hinge for doors cut at right angles, which comprises a series of hinged rods that determine a specific opening movement. Both a helical spring and a damper are provided, which are common in such hinges. However, these elements cannot be transferred to a 45° door hinge.

[0009] DE 20 2019 104311 U1 describes a hinge for a door with an opening of 180°. The two hinge bodies are slightly beveled at the same angle and face each other exactly when the door is closed. The hinge has neither a spring device nor a damping device. Summary of the invention

[0010] The object of the present invention is to eliminate the disadvantages of the known 45° door hinges.

[0011] More specifically, an object of the present invention is to provide a hinge for a 45° door which allows automatic and simultaneously damped closing of the door.

[0012] Another object of the present invention is to provide such a 45° door hinge which can be supplied assembled or separated from the mechanism to facilitate its assembly to furniture.

[0013] Yet another object of the present invention is to provide such a hinge which is small in size and which takes up reduced space inside the furniture in the closed state.

[0014] Still another object of the present invention is to provide such a hinge which is simple to manufacture, low in cost and highly reliable.

[0015] These and other objects are achieved by a 45° door hinge according to the invention having the features listed in the attached independent claim 1 .

[0016] Advantageous embodiments of the invention are apparent from the dependent claims.

[0017] In essence, the invention relates to a hinge for opening and closing a door having a 45° bevel relative to a wall of an article of furniture, the wall of which also has a 45° bevel, the hinge being formed by a first hinge part and a second hinge part adapted to be accommodated in respective seats provided in the wall and the door, each hinge part comprising a first shaped plate or arm and a second shaped plate or holder, respectively, which are interconnected by means of four connecting rods and seven hinge pins or pivot pins, thereby forming the actual hinge assembly, wherein the arm and the holder are received in corresponding separate bases to which they are fixed by means of respective screws, and wherein at least one spring is provided, which is arranged between a pair of the connecting rods so as to exert a force in the closing direction of the hinge.

[0031] With reference to the accompanying drawings, a hinge according to the present invention will now be described in more detail, which is designed for opening and closing a door having a 45° slope, such as Figures 6 to 13 Shown schematically.

[0032] In these figures, the door is shown on the left and is indicated by the reference numeral 2, whereas the wall of the item of furniture to which the door is hinged is shown on the right and is indicated by the reference numeral 1.

[0033] However, the door 2 and the wall 1 (which can be the side, the bottom, the top or also an intermediate shelf of the furniture item) can have a position reversed relative to the position shown, also because the seats S formed therein for accommodating the corresponding hinge parts are exactly the same.

[0034] Similarly, the hinge may be mounted as shown in these figures, or with the positions of its two components reversed.

[0035] Now refer to Figure 1 and 2 , the hinge according to the present invention is described according to its basic components, which is generally represented by the letter C, including a fixed hinge part C1 (in the example shown, the fixed hinge part C1 is installed on the wall 1 of the furniture) and a movable hinge part C2 installed on the door 2.

[0036] The two hinge parts C1, C2 have a generally rectangular elongated shape in plan view and comprise respective bases G1, G2 which, apart from some internal details to be described below, are structurally identical in size to one another so that they can be equally accommodated in any seat S formed in doors and furniture.

[0037] The two bases G1 and G2 house the actual hinge assembly, comprising a first shaped plate 10, having a substantially rectangular profile, which we will call the arm, intended to be housed in the base G1, and a second shaped plate 20, also having a substantially rectangular profile, which we will call the cage, intended to be housed in the base G2, between which is arranged the door movement mechanism, which consists of a seven-axis or seven-pin joint system, which will now be described with reference to the cross-sectional view.

[0038] The door moving mechanism comprises four connecting rods or link bars B1 , B2 , B3 , B4 which are connected to each other and to the respective forming panels 10 , 20 .

[0039] In the drawings, seven connector pins are indicated by reference numerals P1, P2, P3, P4, P5, P6, and P7, and for ease of explanation, Figure 1 In the enlarged view of FIG. 1 , the holes in the connecting rods and forming plates 10, 20 for receiving these joint pins are indicated by the same reference numerals followed by a superscript.

[0040] More specifically, one ends of the outermost connecting rods B1 , B2 are connected at points P1 and P2 located further inside the arm 10 and the retainer 20 , respectively.

[0041] The other end of the connecting rod B1 is connected to one end of one of the two central connecting rods B3 at a point P3, and the other end of the central connecting rod B3 is connected to the retaining frame 20 at a point P6 which is the outermost point relative to the connecting point P2.

[0042] The other end of the connecting rod B2 is connected to one end of another central connecting rod B4 at a point P4, and the other end of the connecting rod B4 is connected to the arm 10 at a point P5 which is the outermost point with respect to the connecting point P1.

[0043] The two central connecting rods B3, B4 are connected to each other at a midpoint P7.

[0044] In the hinged open state, the door 2 is practically aligned with the wall 1 of the furniture item, the connecting rod pairs B1, B4 and B2, B3 being slightly inclined in opposite directions relative to these elements, but without causing an external volume occupation, such as Figure 3 , 3a shown.

[0045] During the hinge closing phase, these connecting rod pairs rotate 90° in opposite directions to position themselves into Figure 5 The configuration shown, in which they protrude in a limited manner beyond the contours of the arm 10 and the cage 20 .

[0046] The connecting rods B1 - B4 are of planar configuration and have a width slightly smaller than the width of the arms 10 and the cage 20 , the joint pins P1 - P7 extending transversely and parallel to the plane of the connecting rods.

[0047] In order to assist the closing of the hinge, elastic means are provided, in this case a strip or leaf spring M, which acts between the connecting rods B1 and B3.

[0048] exist Figure 3-5 In the embodiment, the spring M is arranged inside, that is, below the connecting rods B1 and B3, and Figure 3a In an alternative embodiment, the spring M is placed outside, i.e. above the connecting rod. For the rest, Figure 3a Examples and Figure 3 The same as the embodiment.

[0049] In order to allow the assembly of the two types of springs M described above, one of the connecting rods, namely the connecting rod B3 in the example shown, has at one end thereof an outwardly protruding beak 26, near which a transverse slot 27 is provided on the connecting rod B3. The distal end 28 of the flat surface of the adjacent connecting rod B1 is slightly spaced from the corresponding joint pin P1, thereby defining a gap 29 together with it. The ends M1, M2 of the spring M are curved in an arch shape on the same side, so that one of these arched ends M1 engages with the beak 26 of the connecting rod B3, optionally passing through the slot 27, while the other end M2 engages with the above-mentioned end 28 of the adjacent connecting rod B1, itself arranged in said passing gap 29.

[0050] Of course, the spring M may also be arranged between other pairs of connecting rods, or between the connecting rod and the arm 10 or the retaining frame 20, and a plurality of springs M may also be provided.

[0051] Next, we will refer to Figure 14-1 7Describe the different types of springs.

[0052] The hinge also includes a speed reducer D designed to prevent the hinge from closing suddenly.

[0053] In the embodiment shown in the figures, the reducer D is a shock absorber or damper, which is composed in particular of a cylinder 30 and an associated piston 31 .

[0054] The damper D is accommodated in the seat 21 of the holder 20 , and the rod 32 of the piston abuts against the bottom 22 of the seat 21 .

[0055] In the example shown, the damper D is actuated by a connecting rod B2 which, on the side facing the damper, has a groove 33 which enables it to be in the closed state ( Figure 5 ) partially accommodates cylinder 30.

[0056] In the example shown, the speed reducer D and the spring M are mounted on opposite sides of the cage 20 and the arm 10, respectively, and this arrangement is optimal due to the limited space available.

[0057] However, these components may both be mounted in the holder 20 or the arm 10 .

[0058] The arm 10 and the retaining frame 20 as well as the corresponding bases G1 and G2 are all formed with a 45° slope forward to adapt to the 45° slope of the wall 1 and the door 2 of the furniture article.

[0059] The retaining frame 20 has a roughly hollow parallelepiped shape, which is used to accommodate the damper D and partially accommodate the connecting rods B2 and B3. The retaining frame 20 has a pair of external longitudinal ribs 23 on both sides thereof starting from the front edge, and the length of which extends is about half of the length of the retaining frame 20, which is used for sliding engagement in corresponding opposite grooves 41, and the grooves 41 are arranged in the side walls 40 of the base G2. The retaining frame 20 is arranged between the side walls and has a protruding upper fin 24 at the rear. The upper fin 24 has a transverse slotted hole 25, and the slot 25 overlaps with the screw hole 43 arranged in the thickened part 44 of the rear wall 42 of the base G2.

[0060] By inserting the screw 50 into the slot 25 and screwing it into the screw hole 43 , the retaining frame 20 can be firmly fixed in the base G2 and can be adjusted laterally according to the length of the slot 25 .

[0061] The arm 10 also has a parallelepiped shape, with a hollow front portion 11 which partially houses the connecting rods B1 and B4, and a solid rear portion 12 which is slightly raised in the central portion relative to the bottom of the hollow front portion 11, defining two lateral fins 13 which protrude downwards from said solid portion 12.

[0062] As mentioned above, the corresponding base G1 is externally identical to the base G2, and the same reference numerals are therefore used to distinguish identical or corresponding parts, and it has at the rear a central thickened wall 60 for housing the solid portion 12 of the arm 10, and the wings 13 can slide on the sides of the thickened wall 60, as shown in Figure 2a The axonometric section view can be seen in more detail.

[0063] The aforementioned solid portion 12 of the arm 10 is provided with a longitudinal slotted hole / hole forming a slot 15 which overlaps with a screw hole 61 provided in the aforementioned thickened portion 60 of the rear wall 42 of the base G1 .

[0064] By inserting the screw 51 into the slot 15 and screwing it into the screw hole 61 , the arm 10 can be firmly fixed in the base G1 and can be longitudinally adjusted according to the length of the slot 15 .

[0065] In order to adjust along a third axis (perpendicular to the aforementioned transverse and longitudinal directions), a grub screw 52 is provided, which is screwed into the screw hole 14 of the arm 10 and engages with one of its widened ends 53 below a longitudinal groove 62 arranged in front of the thickened portion 60 of the base 10, and the narrow part 54 of the shaft of the grub screw 52 is inserted into the longitudinal groove 62.

[0066] By providing a longitudinal slot 63 in the rear wall 42 of the base G1 , the widened end 53 of the grub screw 52 can be engaged beneath the slot 62 , which longitudinal slot 63 extends beyond said slot 62 at the front.

[0067] Thus, before screwing in the screw 51 , the arm 10 with the grub screw 52 pre-installed is placed on the base G1 so that the grub screw is located in front of the slot 63 and is slid longitudinally along the base so that the grub screw 52 engages with the slot 62 .

[0068] With the fixing screw 51 loosened, the rotation of the grub screw 52 in one direction or the other determines whether the inclination of the arm 10 relative to the base G1 increases or decreases, thus determining the adjustment along the aforementioned third axis.

[0069] In order to allow the hinge to be easily mounted and securely fixed in the seat S formed in the wall 1 and in the door 2 of the furniture item, a pair of longitudinal ribs 45 are provided on the outside of the side walls of the bases G1, G2, extending from the front bevel for approximately half the length of these bases.

[0070] A protruding rear fin 46 is provided at the rear of the base G1 , G2 , and a hole 47 is provided in the rear fin 46 .

[0071] Accordingly, the seat S formed in the wall 1 and door 2 of the furniture item has a generally inverted T-shaped cross-sectional shape extending in the longitudinal direction, wherein the central stem 70 of the T accommodates the body of the base G1 , G2 and the widened head 71 accommodates the aforementioned side ribs 45 .

[0072] Adjacent to the inner end of the seat S, on the surface of the wall 1 and the door 2, there is a groove 72 capable of receiving the fin 46 protruding at the rear of the base G1 , G2 so that it is flush with the above-mentioned surface.

[0073] The fixing of the bases G1 and G2 in the wall 1 and door 2 of the furniture item, respectively, is carried out by means of screws 55 which pass through holes 47 provided in the fins 46 and are screwed into holes 73 located below in the recesses 72 .

[0074] Now refer to Figure 14-1 7 describes a second embodiment of the invention which differs from the previous embodiment only in that a different spring is used to apply the closing force to the hinge. The structure of the hinge remains essentially the same, with only slight adjustments to accommodate the different types of springs, which will be briefly highlighted and the same reference numerals used to distinguish them from the elements described in the previous embodiment.

[0075] According to a variant of this embodiment, a torsion spring, preferably a double torsion spring, is used, denoted by reference numeral M'. Fig.17a , 17b , 17c, which is selected and implemented to exert a sufficient closing force on the hinge, which is particularly necessary in the embodiment shown, in which the reducer D is located on the opposite side, at a considerable distance therefrom.

[0076] The spring M' is preferably made of harmonic steel and comprises two helical coils 90 which are joined to form a central U-shaped portion and terminate in respective legs 91 in the same direction. The central U-shaped portion is quite pronounced, with its ends 93 bent downwards, in the opposite direction to said legs 91.

[0077] like Fig.14 and 16 As shown, the spring M′ is mounted with its helical coil 90 on a pin P8 attached to the arm 10 of the fixed part C1 of the hinge and extending parallel to the pins P1 - P7 , with its foot 91 facing the movable part C2 of the hinge, resting on an upper abutment wall 95 .

[0078] The downwardly bent end 93 of the central U-shaped portion 92 of the spring M' rests on the connecting rod B1, exerting a force thereon tending to close the hinge.

[0079] In this case, a window 96 is provided in the connecting rod B1, and the bent end 93 of the central portion 92 of the spring M' is located at the junction of the connecting rod and the connecting rod. Fig.14 , 15 The open hinge position transitions to Fig.16 The hinge is inserted into the window 96 when the hinge is in the closed hinge position.

[0080] exist Fig.16 In the closed hinge position, the connecting rod B1 is inclined in a direction opposite to the central portion 92 of the spring M', which passes through the connecting rod B1, thereby applying a force on the connecting rod tending to keep the hinge closed.

[0081] In this second embodiment, the structure of the hinge remains substantially the same, except for the displacement of the adjustment grub screw 52 (whose mounting and operation remain unchanged) under the connecting rod B1 in order to position the spring M'. The grub screw 52 is accessible through the aforementioned window 96 provided in the connecting rod B1.

[0082] Of course, the spring M' may be positioned in such a way as to act between parts of the hinge other than those shown.

[0083] Having described the structure and assembly of the hinge according to the invention, which may be provided with preassembled or separate bases G1 , G2 , two modes of mounting the hinge on an item of furniture will now be described.

[0084] Figures 6 to 12 A first mode is shown, in which the hinge is provided with pre-assembled bases G1 , G2 .

[0085] from Figure 6 First, insert the hinge component C1 into the seat S provided in the wall 1 of the furniture item, as shown by the arrow in the figure, and tighten it by Figure 7 The screw 55 shown is used to fix the Figure 8 status.

[0086] Then insert the hinge part C2 into the seat S of the door 2 and screw it in. Fig. 9 After the corresponding attachment screws 55 are attached, Fig.10 The hinge is shown in an assembled state, wherein a protective cover 80 covering the screws is also shown, which is applied by slotting and / or sliding ( Fig.11 ).

[0087] Fig.12 The hinges of the door are shown in the closed position.

[0088] In the foregoing, for example only, the hinge component C1 is inserted first.

[0089] Of course, starting with inserting hinge component C2 first would not make a difference.

[0090] Fig.13 A different assembly method is shown, in which the bases G1, G2 are first inserted into the corresponding seats S and attached by means of screws 55, followed by the installation of the actual hinge assembly, as previously described, by adjusting the inclination of the arm 10 by means of screwing in the grub screws 52, and attaching the arm 10 and the holder 20 by means of the corresponding screws 51 and 50, with longitudinal and lateral adjustments respectively.

[0091] The hinge according to the invention has small dimensions: a width of about 20 mm, a length of about 67 mm, and in such a small space, adjustment along three Cartesian axes has been inserted the spring M and the damper D. Moreover, its thickness is such that it can be accommodated in a wall 1 and a door 2 with a thickness of 16 mm.

[0092] From the above, it can be seen that the advantages of the seven-pin 45° door hinge according to the present invention are obvious. In addition to its small size, elastic closure and deceleration device, it can also be fully preassembled or provided with a separate supporting base, and the user can decide how to install it.

[0093] Furthermore, thanks to the perfect symmetry of the two hinge parts C1 , C2 , the hinge can be mounted in one direction or the other in two furniture item parts to be connected, the two hinge parts C1 , C2 being accommodated in the same housing S formed in the furniture item parts.

[0094] Of course, the invention is not limited to the particular embodiments described above and shown in the drawings, but many details may be modified thereto within the capabilities of a person skilled in the art without departing from the scope of the invention as defined in the appended claims.
