Description

DESCRIPTION Title of the invention: Deformable jewelry item

[0001] The present invention relates generally to the field of jewelry, more particularly to components such as rings, bracelets or pendants.

[0002] Jewelry components, in particular rings, are known which offer the possibility of exhibiting a telescopic extension movement in an axial direction, as for example disclosed by document EP0642750.

[0003] However, the components of the prior art have the disadvantages of risks of pinching the user in the event of movement of the parts, of offering an inelegant stepped structure which can be caught inadvertently, of not being intuitive during telescopic movement and of being complicated to use.

[0004] The present invention aims to propose a new construction of jewelry components, such as rings, earrings or pendants, offering new mechanical and / or aesthetic possibilities, while facilitating manufacturing. Furthermore, the present invention aims to reduce the risk of pinching the user in the event of movement of the parts, to have an elegant structure and limiting the risk of being inadvertently caught, to be intuitive during movement of the parts and to be simple to manufacture and use.

[0005] Thus, the invention relates, in a first aspect, to an article of jewelry comprising: - at least one first piece, - at least one second part mounted on the first part, and - a deformable envelope secured to the first part and the second part. The second part is thus movable relative to the first part, that is to say it is assembled to the first part in a movable manner.

[0006] This makes it possible to offer a piece of jewelry, in particular a ring or pendant, with a new construction, offering new mechanical and / or aesthetic possibilities, while facilitating manufacturing. In addition, this reduces the risk of pinching the user in the event of movement of the parts, presents an elegant structure and limits the risk of being inadvertently caught, is intuitive during movement of the parts and is simple to manufacture and use.

[0007] Advantageously, the deformable envelope is a network of articulated elements.

[0008] This makes it possible to offer an elegant and easy-to-use piece of jewelry, offering a pleasant and deformable sensation to the touch.

[0009] In other words, the articulated elements of the network together form an outer wall of the deformable (exterior) envelope, the articulated elements being movable relative to each other and articulated to each other in such a way as to make said outer wall deformable. By deformable, we mean here that the deformation of the wall is done while maintaining the dimensions of the articulated elements, without deformation of material. It is only the relative displacements of the articulated elements relative to each other that allow the deformation. The degrees of freedom provided for in the design between the articulated elements thus determine the possible deformations. The jewelry item can therefore take an infinite number of forms, depending on the forces it undergoes, whether it is pressure from the wearer or user, or even the action of gravity on the wall which, when free, can deform under its own weight.Articulated means that the articulated elements are connected while retaining the ability to move relative to each other. This makes it possible to offer a piece of jewelry. with a deformable outer wall, which gives new possibilities to designers to design jewelry item shapes, and gives the user the possibility of having a more tactile interaction with their jewelry, with the possibility of deforming it and playing with it. In particular, the articulated elements linked together to form the network, allow the outer wall to resume, at least partially, its original shape and volume after being subjected to compression, bending or even extension.

[0010] Preferably, the hinged members are formed as a single piece. Preferably, adjacent hinged members are hinged together, or at least some adjacent hinged members are hinged together.

[0011] In a preferred embodiment, the wall is elastically deformable.

[0012] This allows the nominal or initial shape to be restored after being deformed by a constraint, for example a support.

[0013] Advantageously, each articulated element comprises an outer panel.

[0014] Advantageously, the articulated elements comprise interlacings, preferably helical, meshing the articulated elements with each other.

[0015] This allows the articulated elements to be held together and meshed together, so as to ensure mechanical strength.

[0016] Advantageously, the network of articulated elements is arranged to limit the amplitude of movement of the deformable envelope.

[0017] Advantageously, the network of articulated elements is arranged to limit an amplitude of movement of the second part relative to the first part.

[0018] This limits the movement of the parts between them, and ensures their return to their initial position in a simple way.

[0019] Advantageously, the network of articulated elements has a plurality of mesh sizes between the articulated elements.

[0020] Advantageously, the mesh size near the first part or the second part is different from the mesh size away from the first part or the second part.

[0021] Advantageously, the deformable envelope is flexible. By flexible, we mean something that can be folded and / or refolded easily, without breaking or damaging it.

[0022] This makes it easier to make the jewelry item while ensuring smoother and more consistent movement.

[0023] Advantageously, the jewelry item further comprises an elastic part arranged at least partially on or under the deformable envelope, so as to allow elastic return of the envelope.

[0024] This ensures the reversible and intuitive operation of the jewelry item.

[0025] Advantageously, the elastic part comprises a plurality of portions each having an elasticity, and in which the elasticity of at least one of the portions is different from the elasticity of the other portions.

[0026] Advantageously, the elastic part comprises a plurality of portions having identical elasticity.

[0027] Advantageously, at least one articulated element is supported by an elastic part (or elastic member), such as an elastic mesh.

[0028] This makes it possible to give an elastic character to the deformation of the external wall, which returns to its initial shape after having been deformed, under the action of the elastic member. Where the outer wall is supported by the elastic member, it is no longer completely free to deform, particularly under its weight, if the elastic force is greater than the weight of the wall.

[0029] Advantageously, the jewelry item further comprises a return spring arranged to return a movement of the casing or the second part.

[0030] This ensures the reversible and intuitive operation of the jewelry item.

[0031] Advantageously, the movement of the second part is telescopic. Telescopic means a movement in which the elements or parts fit together and slide into each other.

[0032] Advantageously, the movement of the second part is radial.

[0033] Advantageously, the jewelry item further comprises at least one connection between the first part and the second part, and wherein the connection is preferably chosen from a slide, a sliding pivot, a pivot, a hinge, a ball joint or a dovetail.

[0034] Advantageously, the first part and / or the second part is a ring, preferably a rigid ring.

[0035] Advantageously, at least one of said articulated elements is set or decorated.

[0036] This allows us to offer an elegant piece of jewelry that is compatible with the movement of the pieces between them and their setting or decoration.

[0037] Advantageously, the deformable envelope is arranged to cover an external portion of the ring.

[0038] This makes it possible to offer a piece of jewelry with a deformable outer shell.

[0039] Advantageously, the articulated elements comprise a coating, for example a non-stick or self-lubricating coating. The coating may, for example, be made of bronze or metal or polymer, so as to improve the sliding of the articulated elements between them, and make the deformable envelope more supple, flexible and more pleasant.

[0040] Advantageously, the deformable envelope is toric in shape, preferably asymmetrical toric in shape.

[0041] This makes it possible to offer an intuitive and simple piece of jewelry to use and construct, while being pleasant and deformable to the touch.

[0042] Another aspect of the invention relates to an article of jewelry comprising: - at least a first part, with a first side and a second side opposite the first side, and - a deformable envelope secured to the first part and connecting the first side to the second side, so as to cover the first part.

[0043] This makes it possible to provide a piece of jewelry with the advantages mentioned for the present invention.

[0044] Advantageously, the jewelry item further comprises at least one crosspiece arranged between the first side and the second side.

[0045] This makes it possible to stiffen the jewelry item and maintain a constant distance between the two sides of the first piece, as well as maintaining a spacing of the deformable envelope, which can be a network of articulated elements.

[0046] Advantageously, the jewelry item further includes: - at least one second part mounted on the first part.

[0047] Advantageously, the jewelry item further includes: - at least one hinge or clasp, arranged between the first part and the second part, and preferably hidden by the deformable envelope.

[0048] Embodiments and aspects of the present invention may be coupled together, or portions thereof may be used for other embodiments, as far as possible and necessary.

[0049] Other characteristics and advantages of the present invention will appear more clearly on reading the detailed description which follows, of embodiments of the invention given by way of non-limiting example and illustrated by the appended drawings, in which: - figure 1 represents an article of jewelry according to a first embodiment of the present invention, in a sectional view, - figure 2 represents the jewelry item according to a variant of the first embodiment, in a sectional and perspective view, - figure 3 represents a perspective view of the jewelry item according to the first embodiment, - figure 4 represents a detailed view of an articulated element of the jewelry item, from above, - figure 5 represents a detailed view of two articulated elements from below in perspective, - figure 6 represents a detailed perspective view of two articulated elements, - figure 7 represents the jewelry item according to a second embodiment of the present invention, in a sectional view, - figure 8 represents the jewelry item according to a third embodiment of the present invention, in exploded perspective, - figure 9 represents a detailed view of the jewelry item according to the third embodiment of the present invention, in a perspective view, - figure 10 represents a detailed view of the jewelry item according to the third embodiment of the present invention, according to a perspective view opposite the view of figure 9, - figure 11 represents a detailed view of the jewelry item according to the third embodiment of the present invention, in a sectional view, - Figure 12 represents an exploded perspective view of the jewelry item according to a fourth embodiment of the present invention.

[0050] Figure 1 shows a jewelry item 100 according to the present invention. The jewelry item 100 may be, for example, a ring 100, an earring 100 or a pendant 100, without being limited to these examples.

[0051] The ring 100 comprises at least a first part 1 and at least a second part 2 mounted to move relative to the first part 1.

[0052] The ring 100 further comprises a deformable envelope 3 connecting the first part 1 and the second part 2. The deformable envelope 3 is thus integral with the first part 1 and the second part 2. Preferably, the connection between the deformable envelope 3 and the first part 1 and second part 2 is non-removable.

[0053] Preferably, the deformable envelope 3 may be a network of articulated elements 20. The articulated elements 20 are movable relative to each other, which allows the deformable envelope to deform under the action, for example, of pressure from a user's finger.

[0054] The second part 2 is movable relative to the first part 1, for example at a connection 2g, such as a sliding connection, between the first part 1 and the second part 2. The connection 2g between the first part 1 and the second part 2 may also be a sliding pivot, a ball joint, a segment or a dovetail, without being limited to these examples.

[0055] Thus, pressure from the user on an articulated element 20 of the network makes it possible to move this articulated element 20, but also the contiguous articulated elements 20, and gradually makes it possible to move the second part 2 which is at least partially secured to an articulated element 20 (for example by means of an external articulated element 20ex of the network of articulated elements 20). Thus, pressure from the user makes it possible to move the second part 2 along the connection 2g between the second part 2 and the first part 1. In other words, the connection 2g between the first part 1 and the second part 2 makes it possible to promote the movement of the articulated elements 20. Thus, the deformation of the deformable envelope 3 is facilitated, its amplitude can be increased.Furthermore, the deformation of the deformable envelope 3 may also be limited by a stop, for example at the connection 2g, so as to limit the deformation of the deformable envelope 3, and for example avoid jamming at the articulated elements 20. In other words, the external articulated elements 20ex are integral with the first part 1 and / or the second part 2 and the rest of the network of articulated elements 20. The articulated elements 20ex may each comprise a portion attached (for example a base 20b) to the first part 1 and / or the second part 2, and one or more interlacings 20e to be attached to the rest of the network of articulated elements 20.

[0056] Furthermore, the network of articulated elements 20 can limit an amplitude of displacement of the deformable envelope 3, and therefore of the second part 2, in particular relative to the first part 1.

[0057] Furthermore, the ring 100 may comprise an elastic part 4 arranged under or on the deformable envelope 3. In the illustration of Figure 1, the elastic part 4 is arranged under the deformable envelope 3, and comes to bear under bases of articulated elements 20b of the articulated elements 20. This makes it possible to elastically recall the deformable envelope 30. It is possible to provide the elastic part 4 under several bases of articulated element 20b. It is further possible to provide a base 4b for the elastic part 4, which may comprise a network of slender elastic parts (or slender portions) in order to support and / or recall the network of articulated elements 20. The slender portions may extend from the base 4b towards the base of articulated element 20b.

[0058] The first part 1 may be a ring, preferably a rigid ring, and the deformable envelope 3 may cover the first part 1. Preferably, each of the first part 1 and / or the second part 2 may be monobloc, monolithic, made from a single piece, and / or free from internal articulation. Furthermore, the second part 2 is preferably mounted directly on the first part 1.

[0059] The first part 1 may have a longitudinal axis X and a recess arranged to receive a finger of the user along the longitudinal axis X. The first part 1, in particular in the case where it is a ring, has a radial axis Z, preferably passing through a center of gravity of the ring.

[0060] The base 4b of the elastic part 4 can preferably be fixed or secured to the external articulated elements 20ex.

[0061] It is further possible to provide connections (for example sliding connections) between the base 4b and the slender portions of the elastic part 4.

[0062] Furthermore, it is possible to provide different elasticities between the slender portions of the elastic part 4, in order to promote the movement of the second part 2.

[0063] The elastic part 4 is preferably underlying, that is to say it is located under the network of articulated elements 20 and is at least partially masked by it. In other words, the elastic part 4 is arranged between the articulated elements 20 and the first part 1 and / or the second part 2.

[0064] Figure 2 represents the jewelry item 100, for example the ring 100, according to a variant of the first embodiment, in a sectional and perspective view.

[0065] The reference numbers in common between the embodiments are repeated as much as possible and necessary.

[0066] In this embodiment, it is possible to provide symmetry for the network of articulated elements 20, for example with respect to an axis Z. In the same way, it is possible to provide symmetry for the elastic part 4, for example symmetrical with respect to an axis Z1. Therefore, an offset is possible between the axis Z and Z1, which makes it possible to offer significant design freedom, in particular for aesthetic and ergonomic reasons, but also facilitates the sliding of the second part 2 with respect to the first part 1. Note that with reference to FIG. 1, the axes Z and Z1 are identical.

[0067] Figure 3 represents the first embodiment of the ring 100, in order to illustrate its final visual. The ring 100 may include decorative elements. For example, it is possible to provide a setting of 20d diamonds at the level of the articulated elements 20. It is possible to provide a stone (for example precious, fine or organic) or another decorative element instead of or in addition to the 20d diamonds.

[0068] Furthermore, the term “network of articulated elements 20” is understood to mean a set of meshes whose more or less dense interlacing forms a grid, a trellis, or a reticle. In other words, it is a mesh fabric, preferably metallic, that is to say a flexible and thin assembly obtained by the regular assembly of wires, preferably metallic, or interlaced fibers, either by meshes with a single thread, or by weaving with several threads, or formed by a single continuous piece, produced by three-dimensional printing (also called 3D printing). In this case, the interlacings and the panels are advantageously formed in a continuous piece. The articulated elements 20 are shown and described in more detail with reference to Figures 4 to 6.

[0069] Figure 4 shows a detail view of an articulated element 20 from above.

[0070] Here, the term "top view" means the view from the outside of the ring 100 when the articulated element 20 is assembled in a network of articulated elements 20 to form the envelope 3, perpendicular to the surface of the envelope.

[0071] Each articulated element 20 comprises, as described above, an outer panel 20p. In the example shown in Figure 4, each articulated element 20 comprises four interlacings 20e, preferably helical.

[0072] The articulated element 20 is shown with a 20d diamond set on the outer panel 20p. For example, the dimension of the 20p panel is approximately 1.60 mm on each side. The mobility of the 20p panels makes it possible to create reflections and light effects in the set stones. It is also possible to provide, in addition to or instead of the setting, a smoothing of the 20p panels or to create textures on the 20p panels, or a surface heat treatment to give, for example, a satin or colored appearance. This results in a new kind of jewelry item, offering an original aesthetic and allowing the user to interact tactilely with their jewelry item 100, to deform it or create light effects on the 20p panels or the set stones.

[0073] 20g claws can be provided to hold 20d diamonds in place.

[0074] Figure 5 shows a detailed view of two articulated elements 20 from below in perspective.

[0075] Here, the term “bottom view” means the view from inside the ring 100 when the articulated element 20 is assembled into a network of articulated elements 20 to form the envelope 3.

[0076] As described above, the articulated elements 20 each comprise an articulated element base 20b.

[0077] The articulated elements 20 are interlaced: a 20e interlacing of an articulated element 20 is interlaced with a 20e interlacing of another neighboring articulated element 20. Thus, the 20e interlacings are in a position of engagement with each other, that is to say are held together, with a clearance. This makes it possible to mesh the articulated elements 20 together, so as to connect them. In other words, the network of articulated elements 20 is also a network of meshes.

[0078] It is possible to provide a clearance between the 20p panels of the articulated elements 20. The clearance between two articulated elements 20 is typically 0.1 to 0.2 mm at the level of the 20p panels. This clearance is not contradictory with the fact that the surfaces of the panels are substantially in continuity with each other to form the outer wall.

[0079] Figure 6 shows a detailed perspective view of two articulated elements 20.

[0080] The articulated elements 20 are interlaced with each other, via the interlacings 20e. The articulated elements 20 typically measure 1.6 mm in height.

[0081] Figure 7 shows a second embodiment of the ring 100.

[0082] It is possible to modify the dimensions of the ring 100 in order to provide, for example, more rounded shapes for the deformable envelope 3. Thus, in a preferred embodiment, the envelope deformable 3 is toric in shape as illustrated in figure 7, and in particular asymmetrical toric.

[0083] The articulated elements 20 are preferably made by 3D printing or by welding (or sintering). The articulated elements 20 can be made of any suitable material, such as gold, silver, steel, or plastics. The same applies to the first part 1 and / or the second part 2. The elastic part can be made of elastomer or silicone, for example.

[0084] The elastic part 4 may be an elastic mesh, also called a “bumper” in English (i.e. bumper). The elastic mesh 4 forms a frame which supports and sustains the network of articulated elements 20. The elastic mesh may be produced by 3D printing. The elastic part 4 may have a lattice structure or be made of a composite material.

[0085] Preferably, the elastic part 4 may be an elastic mesh comprising a network of elastic elements, with for example solid portions separated by perforated portions. The solid portions are preferably arranged opposite the bases of the articulated elements 20b so as to support them elastically.

[0086] Thus, when the user presses on the jewelry item 100, at the level of one or more panels 20p, the articulated elements 20 are elastically supported, that is to say they return to their initial position once the user's pressure has ended.

[0087] This also provides resistance to the user's pressure, which is pleasant to the touch and allows for play with the wall of the ring 100.

[0088] The perforated portions of the elastic mesh also contribute to the good mechanical strength of the mesh, in particular by limiting blistering, plastic sinking or deterioration of the elastic mesh.

[0089] Preferably, the stitches, which are the repeating pattern of the elastic mesh, are diamond-shaped when viewed from above.

[0090] Preferably, the elastic mesh consists of meshes of similar or proportional (or corresponding) size to the meshes of the network of articulated elements. In practice, the meshes of the network of articulated elements and the meshes of the elastic mesh are not identical.

[0091] Alternatively, the elastic mesh may be wider or looser, i.e. the mesh size is larger, and elastic support is provided only, for example, for half of the bases of the articulated elements 20b.

[0092] Figure 8 shows the jewelry item according to the third embodiment of the present invention, in exploded perspective.

[0093] The ring 100 is illustrated with the elastic part 4, as well as the first part 1.

[0094] The elastic part 4 can thus match the internal shape of the network of articulated elements 20, so as in particular to support it at the level of a plurality of supported articulated elements 20. The elastic part 4 thus also forms a network, preferably corresponding to the network of articulated elements 20. Alternatively, it is possible to provide that there is not necessarily a correspondence between the network of articulated elements 20 and the network of the elastic part 4: it is possible to provide a network bar of the elastic part 4 for several articulated elements 20, without all the articulated elements 20 being directly supported by the network of the elastic part 4. Thus, it is possible to adjust the rigidity and flexibility, by adjusting the number of articulated elements 20 supported directly by the network of the elastic part 4, for example from 0 to 30%, 0 to 50%, 0 to 75% or 0 to 100%.

[0095] The external articulated elements 20ex are preferably connected or secured to the first part 1.

[0096] Alternatively, the 20ex elements are not directly connected to part 1.

[0097] The 20ex elements are connected to rigid rings 21 ex, preferably directly made during printing or welded. It is possible to weld these rings 21 ex to bars 30 and 31 and then fix the whole thing on the part 1 by fixing the bars 30 and 31 of the ring 100 (by screwing or pin), which simplifies disassembly, assembly and after-sales service.

[0098] Figure 9 shows a detail view of the jewelry item according to the third embodiment of the present invention, in perspective view.

[0099] The ring 100 may comprise one or more crosspieces or bars 30, 31, as indicated previously in order to maintain the lateral spacing of the network of articulated elements 20, preferably via the rigid rings 21 e.g. In the example of Figures 9 and 10, the ring 100 comprises a first crosspiece 30 and a second crosspiece 31 illustrated in Figure 10.

[0100] The first crosspiece 30 is shown at the top and the second crosspiece 31 is masked by the first part 1 and is fixed by one (or more) screws 41. The first part 1 is thus screwed and secured to the crosspiece 31 by means of the screw 41.

[0101] Figure 10 shows a detail view of the jewelry item according to the third embodiment of the present invention, in a perspective view opposite the view of Figure 9.

[0102] The crosspiece 30 is fixed and secured to the first part 1 by means of one (or more) pins 40, housed in a housing 40h. The crosspieces 30, 31 are welded or 3D printed to be made secure to the first row of external articulated elements 20ex or the rings 21 ex.

[0103] In a particular embodiment, the screw heads 41 and pins 40 are masked by welding or brazing, while allowing disassembly, in particular for repair and maintenance.

[0104] Figure 11 shows a detail view of the jewelry item according to the third embodiment of the present invention, in a sectional view.

[0105] It is possible to see the screws 41 screwed into tapped holes 41 h of the crosspiece 31. Similarly, it is possible to see the pin 40 housed in the calibrated hole 40 h of the crosspiece 30 (and of the first part 1).

[0106] The edges of the articulated network, also called external articulated elements 20ex, can be in one piece with the first part 1 or integral with the rigid rings 21 ex. They are preferably directly produced by 3D printing. In other words, the external articulated elements 20ex are integral, on one side, with the rigid rings 21 ex, and on the other side, with the rest of the network of articulated elements 20.

[0107] In Figures 9 to 11, the remainder of the network of articulated elements 20 is masked for better readability of the figures.

[0108] Figure 12 shows an exploded perspective view of the jewelry item according to a fourth embodiment of the present invention.

[0109] Figure 12 shows a fourth embodiment which is a bracelet 200.

[0110] The bracelet 200 comprises a first part 101 and a second part 102 movably mounted on the first part 101. [01 1 1 ] The first part 101 and / or the second part 102 preferably comprises a network of articulated elements 20. The second part 102 can be made with a rigid mesh (or with a rigid part having a mesh appearance) and the first part 101 made with a flexible mesh.

[0112] The bracelet 200 further comprises a hinge 107 connecting the first part 101 and the second part 102, allowing a rotational movement between them, so as to allow the bracelet 200 to be opened.

[0113] The bracelet 200 further comprises a clasp or pusher 105, 106 connecting the first part 101 and the second part 102, making it possible to fix the parts together, so as to allow the bracelet 200 to be closed. The clasp comprises a first part 106 fixed to the first part 101, and a second part 105 fixed to the second part 102.

[0114] The bracelet 200 further comprises an elastic part (not shown), preferably made of polyurethane, housed in the first part 101 and / or in the second part 102.

[0115] The bracelet 200 further comprises a first internal cover 108, preferably rigid in order to close an internal space of the first part 101, and to mask if necessary the elastic part (not shown).

[0116] The bracelet 200 further comprises a second internal cover 103, 104, preferably rigid in order to close an internal space of the second part 102, and to mask if necessary the elastic part (not shown). The second cover 103, 104, can be made in several parts, with a removable cover 103, in order to facilitate the repair and maintenance of the network of articulated elements 20 and / or of the elastic part (such as for example its replacement). It is also possible to provide such a removable cover for the first part 1. The removable cover can be fixed by one or more screws (for example four) to the edges of the cover 104.

[0117] The external articulated elements 20ex are integral with the hinge 107 and the clasp 105, 106, on one side, and with the rest of the network of articulated elements on the other side. Alternatively, the hinge 107 and the clasp 105, 106 may be integral with the covers 104, 108. The hinge 107 and the clasp 105, 106 may be masked by the network of articulated elements 20. The hinge 107 and / or the pushers 105, 106 could be under the link so that the free ends of the link would be at the level of the clasp or the hinge.

[0118] The external articulated elements 20ex can be integral with the covers 108, 104, and fixed to them, in particular by a base 20b.

[0119] It will be understood that various modifications and / or improvements obvious to those skilled in the art may be made to the various embodiments of the invention described in the present description.

[0120] In particular, reference is made to the possibility of having other dimensions or other materials for the different elements, for example the first part, the second part, the deformable envelope, the interlacings, without being limited to these. It is possible to provide that the elastic part 4 supports a single articulated element 20 or that the elastic part 4 is overmolded with the network of articulated elements 20. Thus, it is possible to provide a gel filling at each articulated element 20 or an underlying torus formed from gel. It is furthermore possible to provide that the elastic part 4 also acts as a bumper.

[0121] More generally, it is also possible to provide a support arranged between the first part 1 and / or the second part 2 and the envelope. This support can be elastic as mentioned above with the elastic part 4, but also rigid, to form a stop against deformations of the outer envelope. The support can also be a combination of elastic portions and rigid portions.

[0122] It is possible to combine the embodiments as much as possible or necessary.
