Description

Background Art

[0002] The applicant noted that in developing footwear, especially Kangoo When it comes to designing a rebound sneaker, some solutions can integrate the damping system into the sole of the product, making it possible to make changes during walking, running and even sports exercises.

[0003] Such damping systems consist of a spring element, such as one or more leaf springs, which compress under the weight of the user, reducing the transmitted impact forces, especially on the spine, and relax to generate a propulsion force, thereby improving the user's movement ability, especially jumping ability, and reducing the force required to carry out normal movements. Therefore, in addition to sports activities, these solutions are also particularly attractive for helping people with limited mobility, especially those undergoing limb rehabilitation training.

[0004] The Applicant has noted that the solutions proposed so far suffer from various limitations.

[0005] In particular, the systems proposed so far are extremely cumbersome and are limited to use with special footwear adapted to the damping system. As a result, the use of such footwear has a significant impact on the user's gait and is not comfortable to wear on a daily basis, so its use is limited to short periods of physical exercise.

[0006] Applicants have also noted that such specialized footwear is made of a hard material, which allows for control of the forces generated when the spring element is compressed and relaxed. This design also significantly reduces the comfort of the user, as the hard shoe cannot adapt to the user's morphology and / or movements. As a result, the ability to walk or run in a shoe that includes such a damping system is reduced, as the user's foot, and in particular the ankle, is constrained by the shoe structure.

[0007] Therefore, the applicant believes that, to date, there is no satisfactory alternative damping system that can be used to improve the user's daily walking comfort or facilitate long-term physical activity. Utility Model Content

[0008] The utility model aims to improve the above-mentioned situation.

[0009] More specifically, the present invention aims to remedy the above-mentioned drawbacks by proposing a damping system for articles which is compact enough to be integrated without difficulty into footwear-type articles and which facilitates walking movements while providing the user with better resilience and propulsion.

[0010] To this end, the purpose of the utility model first relates to an article damping system, the system comprising:

[0011] A rigid support member having at least one surface, called a receiving surface, extending in a plane; and a leaf spring having a first end and a second end, the leaf spring being arcuate between the two ends.

[0012] In other words, the leaf spring exhibits a curvature when at rest, and deforming the leaf spring by increasing or decreasing the curvature generates an opposite restoring force. In contrast, the rigid support resists deformation and is preferably sized to withstand a force equal to the maximum restoring force that the leaf spring can generate.

[0013] For example, the dimensions of the leaf spring allow reversible deformation along an angular interval corresponding to the range of use of the leaf spring, the extreme positions of which are associated with the maximum restoring force, and the rigid support does not deform or deforms very little under a force equal to the maximum restoring force.

[0014] Obviously, the rigidity of the support and / or the elasticity of the leaf spring is relative to the axis of action of the forces. For example, the support should be dimensioned to provide a high resistance to deformation along a certain axis (for example, an axis perpendicular to the plane of the force-bearing surface). At the same time, the leaf spring should be dimensioned to resist longitudinal forces and lateral torsion forces in order to prevent deformation of the leaf spring other than a change in curvature.

[0015] It is also known to those skilled in the art that the materials of the support and the leaf spring should be selected in combination with their sizes. For example, a support having a composite structure can be used, which includes a support made of wood or Layers of honeycomb plastic core covered.

[0016] Advantageously, the system comprises first assembly means between the first end and the support along which the leaf spring extends along a convex trajectory so that the second end is in contact with the receiving surface and can move in a plane when compressing and / or relaxing the leaf spring.

[0017] In other words, the assembly between the first end and the support (called first assembly) allows the leaf spring and the support to be connected at the first end, while the second end is free. This design enables the first end to promote the transmission of restoring forces from the leaf spring to the support, so that, depending on a more or less evenly distributed weight, the first end generates a thrust on the support or even on the middle part of the leaf spring.

[0018] It can be seen here that the first assembly means allow the leaf spring to move relative to the support, preferably by means of a pivot connection. For example, the first assembly means allow the first end to rotate relative to the support along a first axis, for example along a first axis in the plane of the receiving surface, or even along a plane parallel to the plane of the receiving surface, and the second end to move along a second axis perpendicular to the first axis and in the plane of the receiving surface.

[0019] In addition, the combination of leaf spring and support member can determine the maximum compression position of the leaf spring, at which the leaf spring abuts against the support member. When determining the dimensions of the leaf spring and the support member and selecting their materials, the end position determined by the leaf spring abutting against the support member should be taken into account.

[0020] Due to the use of the utility model, the damping system can use a single leaf spring, which is compressed and relaxed along the planar support to generate a restoring force and a thrust along a specified direction. The damping system has a more compact design and is easy to be integrated into articles, especially into the soles of footwear.

[0021] In an advantageous embodiment of the invention, the damping system comprises holding means for the second end to be in contact with the receiving surface.

[0022] It can be seen here that the retaining device can prevent the second end from being disengaged from the receiving surface, or more generally, can limit the mobility of the leaf spring so that it can only perform compression and relaxation movements against the support. This design prevents foreign matter from entering between the second end and the receiving surface, and also prevents any turning of the leaf spring relative to the support, such as rotation around the first assembly device.

[0023] Preferably, the retaining device comprises a first elastic reinforcing member which is assembled with the support member and the intermediate portion of the leaf spring.

[0024] In other words, the first elastic reinforcement can ensure that the second end is kept in contact with the receiving surface with minimum force under any circumstances, for example, preventing the leaf spring from relaxing beyond a certain extent with minimum force, or operating with minimum force when the damping system rises or flips over.

[0025] In one embodiment, the retaining device comprises a housing for receiving the support member and the leaf spring, the housing preferably being made of a permeable and / or flexible and / or semi-rigid material.

[0026] It can be seen here that the housing limits the possible movement of the support and the leaf spring by confining them to a defined volume. In order to allow the leaf spring to deform, the housing itself is semi-rigid and / or flexible, i.e. it can be compressed and relaxed until a maximum volume is reached, which determines the maximum relaxation of the leaf spring and prevents the second end from detaching.

[0027] Furthermore, to avoid various pressure effects, the housing may be chosen to have a permeability that allows air to pass freely but at the same time blocks the infiltration of any water, snow or other non-gaseous matter that might weigh down or clog the system.

[0028] In a particular embodiment, the system includes a friction reducing device between the second end and the receiving surface.

[0029] It can be seen here that the friction-reducing device can limit the wear of the second end and the receiving surface and avoid forces between the two elements, in particular adhesion forces that cause irregular behavior between the second end and the receiving surface.

[0030] Preferably, the friction reducing means comprises at least one roller mounted between the second end and the receiving surface.

[0031] In other words, the at least one roller acts as an intermediary between the second end and the receiving surface, and rotation of the at least one roller cooperates with movement of the second end relative to the receiving surface in at least one direction.

[0032] Of course, various embodiments of at least one roller can be designed, for example, a plurality of bearings are mounted on the second end and are oriented in the direction of the receiving surface, or vice versa, are mounted on the receiving surface at intervals according to the longitudinal displacement of the second end. According to another example, a roller is mounted on the second end, which engages with a groove arranged on the receiving surface and defining a longitudinal gap of the second end.

[0033] In another embodiment, the friction reducing device comprises a non-stick coating disposed between the second end and the receiving surface.

[0034] For example, the non-stick coating is arranged on the second end and / or the receiving surface and is made of a non-stick material, such as polytetrafluoroethylene, i.e. This design makes it possible, inter alia, to reduce the number of components used and the volume of the damping system.

[0035] In a specific embodiment, the damping system comprises a first guide for guiding the second end to translate relative to the receiving surface.

[0036] In other words, the first guide device can limit the translational movement of the second end along an axis (such as the above-mentioned second axis). Of course, the first guide device also allows the second end to move in other directions according to the designed specific gap.

[0037] Preferably, the first guide device comprises two side guides assembled with the support element and arranged on both sides of the receiving surface.

[0038] For example, the side guides and the support member form an integral component or two separate components assembled together. For example, the side guides are arranged only in the longitudinal spacing of the second end, and their spacing corresponds to the width of the second end so as to accurately guide the movement of the second end, or are arranged along the entire support member and in accordance with the width of the support member to ensure that the second end is in contact with the support member.

[0039] In another embodiment, the first guide means comprises a second rod assembled with the second end and at least one hole provided on the support, the at least one hole receiving the second rod and ensuring its movement along the at least one hole. In other words, the at least one hole defines the longitudinal spacing of the second end, and the translation of the second rod in the at least one hole corresponds to the translation of the second end and therefore also to the compression and / or relaxation of the leaf spring. For example, the second rod is fitted in the at least one hole so as to maintain contact between the second end and the receiving portion in the same manner as the above-mentioned retaining means.

[0040] In one design, a hole is provided along the receiving surface, the second rod is oriented along a third axis perpendicular to the plane of the receiving surface, and moves along the second axis. In another design, two symmetrical holes are provided on the side edge of the support, such as the above-mentioned side guide, and the second rod is parallel to the first axis and moves along the second axis.

[0041] Preferably, the second rod is a detachable pin.

[0042] It can be seen here that the removability of the pin facilitates the assembly and disassembly of the damping system, while at the same time, connecting the pin to the object according to different designs while retaining the relevant characteristics of the second rod mentioned above.

[0043] In another embodiment, the leaf spring has an inner side facing the receiving surface and an outer side opposite to the inner side, and the damping system comprises an auxiliary damping device arranged along the receiving surface and / or the outer side, wherein the auxiliary damping device is made of elastic material.

[0044] It is known here that auxiliary damping devices can avoid and / or limit impacts without the need for additional spring elements and in particular can make the damping system run quietly. For example, auxiliary damping devices arranged along the receiving surface can be provided to avoid any direct impact when the support comes into contact with the ground or the like, as well as auxiliary damping devices arranged along the outer side, for example, replicating the sole and allowing the damping system to be attached.

[0045] In one embodiment, the damping system includes a second longitudinal elastic reinforcement member assembled with the first end and the second end.

[0046] It can be seen here that the second elastic reinforcement member generates a longitudinal restoring force that can make the leaf spring more easily relax or limit its compression, such as compression exceeding a predetermined threshold. The second elastic reinforcement member can be added all at once, or the size can be adjusted individually according to the weight of multiple users or the type of items installed by the damping system to adjust the performance of the damping system. In a specific embodiment, the support member has at least a portion of a U-shaped cross-section, forming a groove, and the second end moves in the groove.

[0047] It can be seen here that the U-shaped cross section of the support member can increase its deformation resistance under the action of the restoring force of the leaf spring, thereby reducing the volume and weight of the support member under the same deformation resistance. In addition, the U-shaped cross section of the support member has two side edges, forming the above-mentioned side guides, etc., and guiding the second end during the translation process. For example, the support member has a U-shaped cross section along the receiving surface and / or along the portion of the support member that may deform under the action of the restoring force.

[0048] It is also known to those skilled in the art that the choice of the material of the support can be adapted to the design of the U-shaped cross section. For example, the support has a solid structure made of a rigid and lightweight material such as aluminum, etc. With a U-shaped cross section, a lighter material and / or a simpler structure can be selected for implementation with equal rigidity.

[0049] In one embodiment, the first assembly device includes a first component having a U-shaped cross-section opposite to the groove along a first distal portion, and the first component is assembled to the support along a first proximal portion by at least one first pin passing through the support and the first component, and the first end is arranged between the at least one first pin and the first distal portion.

[0050] It is understood here that the concept of proximal and distal portions will take into account the position of these portions relative to the longitudinal center of the leaf spring and the support. In other words, the orientation of the first component makes the first proximal portion closer to the center of the leaf spring and the support than the first distal portion.

[0051] Furthermore, the first pin is arranged to extend transversely to the groove, thereby forming a first obstacle to the movement of the first end in the groove, and is longitudinally positioned along the first proximal portion, and the first distal portion completes and closes the groove, forming a second obstacle to the movement of the first end in the groove.

[0052] It is known to those skilled in the art that the first end is held in a position between at least one first pin and the first distal end so that it cannot be easily disengaged from the support member. For example, this positioning is complementary to or alternative to other first assembly means described below, thereby allowing the first end to have a certain freedom of movement while keeping it assembled with the support member.

[0053] It is also known to those skilled in the art that the cooperation of the U-shaped cross section of the support member and the U-shaped cross section of the first component can greatly improve the rigidity of the assembly formed by them to resist the torsion that may cause the support member to deform and the leaf spring to move off the axis. This improvement in rigidity will also be explained in the following embodiments.

[0054] In particular, this design can greatly release the rotation of the first end along the first axis while minimizing friction or any other reaction forces and allowing the leaf spring to relax and compress with minimal deformation of the first end.

[0055] Preferably, the first assembly device further comprises a detachable pin which passes through the support and the first component and is arranged between the at least one first stud and the first distal portion, the first end being arranged between the at least one first stud and the pin.

[0056] It can be seen here that the pin replaces the first distal part and becomes the second obstacle for the movement of the first end in the groove, so that the first end can be set between at least one first column pin and the pin, the assembly dimensions of the first end and the support can be independently designed and determined, and the support can be strengthened by limiting the torque between it and the first distal part.

[0057] Additionally, as discussed above, the removability of the pin facilitates assembly and disassembly of the damping system, as the first end may be in place prior to engagement with the pin.

[0058] In another embodiment, the damping system further comprises a second component having a U-shaped cross-section along a second distal portion opposite to the groove, the second portion being assembled to the support member along a second proximal portion by at least one second pin passing through the support member and the second component, and the second end being located between at least one second pin and the second distal portion.

[0059] It can be seen here that according to the symmetrical design of the damping system, the second component and the second pin can be assembled to the first component and the first pin in a complementary manner, or combined with different first assembly devices, or according to the asymmetrical design of the damping system, assembled according to the size that adapts to the different displacement intervals of the second end.

[0060] Furthermore, the concept of the second distal and proximal parts should take into account their position relative to the central longitudinal position of the leaf spring and the support, and the strengthening of the leaf spring and the related advantages of the second end sliding in the groove are similar to those described for the first part and the first end.

[0061] In another embodiment, the first assembly device comprises:

[0062] a hinge assembled with the first end and the support member; or

[0063] a block made of a resilient material and assembled with the first end and the support member; or

[0064] a half-hinge assembled with the first end and the support, and a pivot connection disposed between the half-hinge and the support; or

[0065] a screw-nut assembly assembled with the first end and the support member; or

[0066] a first rod assembled with the first end and at least one hole provided in the support; or a removable pin assembled with the first end and at least one hole provided in the support. It is known here that the first assembly means can be realized in various forms and selected by professionals in the relevant technical field according to various criteria, including light weight, wear resistance and deformation resistance, the allowable rotation clearance of the first end relative to the support compared with the angular deformation interval of the leaf spring, the possible displacement interval given to the first end, the ease of assembly and / or disassembly of the damping system or the economy criteria. Various other first assembly methods can also be considered, such as simple bonding methods.

[0067] In another embodiment, the support member includes a frame and a sliding member, the frame has a U-shaped cross-section, the cross-section of the sliding member is at least partially rectangular, the frame and the sliding member are embedded together to form a translation guide along an axis parallel to the movement axis of the second end, the first device for assembling the first end to the support member is configured to assemble the first end to the frame, and the damping system also includes a second assembly device for assembling the second end to the sliding member, and the U-shaped and rectangular cross-sections extend from the surface opposite to the receiving surface.

[0068] In other words, the second end is assembled with and in contact with a sliding part having a receiving surface, the sliding part itself is guided in translation relative to the frame, and the second end can move in a plane when the leaf spring is compressed and / or relaxed. Therefore, the movement of the second end in the plane is accompanied by the guidance of the sliding part and the frame. For example, the configuration of the translation guide between the frame and the sliding part can make the second end assembled with the sliding part translate along the above-mentioned second axis.

[0069] It is also known to a person skilled in the art that the guide between the slide element and the frame can, by means of its U-shaped and rectangular cross section, counteract the torsion and rotation of the leaf spring in addition to the compression and / or relaxation movement of the leaf spring, thereby reinforcing the movement of the leaf spring from the side. Since the U-shaped cross section and the rectangular cross section extend from a surface opposite to the receiving surface, they do not influence the compression of the leaf spring, so that the leaf spring has the same end position, for example until the leaf spring rests against the support element.

[0070] Furthermore, since the frame has a U-shaped cross section, the means for receiving items can be arranged inside the U-shaped cross section, so that the damping system can maintain its compactness despite the U-shaped cross section and the rectangular cross section extending from the face opposite to the receiving face.

[0071] Furthermore, it will be appreciated that just as the first assembly means allows the first end to move relative to the frame according to a pivot connection, the second assembly means allows the second end to move relative to the slide member according to a pivot connection, for example according to a fourth axis parallel to the first axis.

[0072] Preferably, the frame is mounted on the sliding member, and the support member further comprises a guide member having a vertical or U-shaped cross section, the guide member being assembled with the frame so that the sliding member cooperates with the frame.

[0073] It can be seen here that the arrangement of the guides can partially block the opening formed by the U-shaped cross section of the frame, while the right-angled or U-shaped cross section completes and closes the opening.

[0074] Thus, when the U-shaped frame is mounted on the rectangular slide, this design prevents or limits any rotation of the frame relative to the slide and keeps it moving along the above-mentioned translation guide. Depending on the design, the guide and the frame can be assembled as a single unit to receive the slide or as two separate units, for example, after the slide is mounted on the frame.

[0075] In another embodiment, the sliding member includes a first portion having a rectangular cross section and engaging with the frame, and the sliding member also includes a second portion having a U-shaped cross section.

[0076] It is known here that this design makes it possible to produce a support, i.e. a frame and a sliding element assembly, whose two longitudinal ends are U-shaped in cross section and which, in particular, allows the reception of an object or a part of an object along these two ends, which ensures better stability of the object when it is equipped with a damping system. For example, receiving means are provided for moving the means forwards and backwards respectively along the second part and the frame, which extend vertically beyond the U-shaped and rectangular cross section of the support, thus making it possible to maintain the compactness of the object equipped with the damping system.

[0077] Preferably, the first part and the second part are assembled from two separate elements.

[0078] It is known to those skilled in the art that this design can make it easier to manufacture the first and second parts and assemble the second part to the first part so that the second part extends in the same plane as the frame and has a receiving surface.

[0079] In another embodiment, the damping system comprises a second guide for translation of the sliding member relative to the frame.

[0080] It can be seen here that the second guide device facilitates the translation of the sliding component and the frame, thereby promoting the movement of the second end along the second axis, or limiting the movement of the sliding component and the frame assembled according to a certain gap.

[0081] Preferably, the second guide device comprises a guide member assembled with the sliding component, and the frame is provided with at least one hole, whose axis is parallel to the moving axis of the second end, and the at least one hole receives the guide device and ensures its movement along the at least one hole.

[0082] In other words, similar to the first guide device, the at least one hole defines the longitudinal movement interval of the sliding component, and the translation of the guide member in the at least one hole corresponds to the translation of the sliding component, and further extends to correspond to the translation of the second end, that is, corresponds to the compression and / or relaxation of the leaf spring.

[0083] In one embodiment, the second assembly means comprises second guiding means.

[0084] It can be seen here that the second assembly device and the second guide device have a connection design, which can ensure that the second end is assembled with the sliding component and guide the second end and the sliding component to translate so that they become a whole relative to the frame at least along the second axis.

[0085] Therefore, in the connection design of the aforementioned embodiment, the guide member can be a detachable assembly screw that can connect the sliding component and the second end together, or can be another element in the second assembly device that is connected to the second end as a whole, such as a hinge described below. According to another example, the guide device is a pin extending from the second end or a component that is connected to the second end as a whole and engaging with at least one hole.

[0086] In another embodiment, the second assembly device comprises:

[0087] a hinge assembled with the second end and the slide member; or

[0088] a block made of elastic material and assembled with the second end and the sliding member; or

[0089] a half hinge assembled with the second end, and a pivot connection disposed between the half hinge and the sliding member; or

[0090] A screw-nut assembly is assembled with the second end and the sliding member.

[0091] It can be seen here that, like the first assembly device, the second assembly device can also be implemented in various forms and selected by professionals in the relevant technical field based on various criteria, including lightness, wear resistance and deformation resistance (depending on the force it withstands), the clearance of the second end relative to the sliding part, and the risk or economic criteria of transmitting torque to the leaf spring.

[0092] In a variant embodiment, the sliding member and the frame are nested in the second end longitudinal extension.

[0093] In a variant embodiment, the sliding member is nested with the frame in a portion of the frame that longitudinally coincides with the second end.

[0094] It can be seen here that the positioning of the sliding part is selected in combination with the assembly of the sliding part with the second end and the assembly of the damping system with the object. Therefore, positioning the sliding part in the longitudinal extension of the second end can maximize the length of the frame without causing any interference to the sliding part, so that it can be assembled with the object in a more stable manner. In other words, this positioning method can maximize the use of the space under the frame to fix the object, for example for hanging the object. Conversely, arranging the sliding part in the part of the frame that coincides with the second end longitudinally can minimize the overall length of the damping system, thus providing a more compact solution if the fixing of the object allows.

[0095] A second aspect of the present invention relates to an article, comprising at least one sole accommodating the damping system according to the first aspect of the present invention.

[0096] In this patent specification and any description, sole refers to the part of an article that bears the weight of the article and / or user during movement and / or use.

[0097] In other words, the sole is an intermediary between the article and the ground and / or other products, and the damping system can reduce vibrations at the sole and cooperate with the movement. For example, the damping system is arranged near or inside the sole, and the sole forms a shell as described above.

[0098] Preferably the article is footwear, the mounting means of the damping system being arranged along the heel of the footwear and the leaf spring extending towards the front of the footwear.

[0099] In other words, the damping system is accommodated in the sole of the footwear, for example, is located below the sole and is detachable, and the support has fastening means for the footwear, or is located inside the sole in a compact design.

[0100] It can also be seen that the damping system is oriented to match the movement of the user's ankle when walking, which greatly increases the user's comfort compared to previous solutions, while generating a propulsion force when the leaf spring relaxes, i.e. when the user lifts his foot, thereby reducing the force required when walking, running or jumping.

[0101] In a special design, there are also footwear that uses multiple damping systems, for example, special shoes such as tap dance shoes, which contain two different damping systems at the front and back ends to match the user's specific movements.

[0102] According to another design, the footwear is provided with a displacement device, for example an integral or separate displacement device between the front and rear displacement devices, and the damping system is arranged between the sole of the footwear and the displacement device.

[0103] Obviously, we provide a plurality of articles that can accommodate the damping system according to the first aspect of the utility model in the same way. For example, these articles belong to a group of articles, including:

[0104] Prosthetic or robotic type prostheses, such as those associated with footwear; and

[0105] Seating, such as furniture, wheelchair seats, bicycle or motorcycle seats, car seats or saddles; and

[0106] Single suspension devices, such as bicycle pedals, balance bikes, skateboards, single boards, scooters suspension devices; and

[0107] Land vehicle suspensions, such as car, trailer or trolley suspensions; and

[0108] Suspension devices for watercraft used to slow down changes in the water level, or as "foils" for suspension, such as the suspension devices of watercraft such as catamarans, motorboats, sailboats, hydrofoils or jet skis; and

[0109] Aircraft wing suspension devices capable of attenuating air changes; and

[0110] Suspension device for bedding, baby cradles or bassinets.

[0111] The exact dimensions of the damping system, the choice of material and the curvature of the leaf springs are adapted to the article in which they are housed. In one embodiment, the sole and the support of the article form an integral element.

[0112] It is hereby understood that the sole of the article at least partially forms a support for the damping system accommodated by the article, in particular in the case where the article and the damping system are designed to be connected or the damping system elements are directly mounted on the sole of the article. Such a design simplifies the overall structure of the article accommodating the damping system, by reusing the structure of the article to form the fixed part of the damping system, and the mobile part which may consist of a leaf spring and optionally other elements of the support that move directly relative to the sole.

[0113] Of course, if the support itself is made of several separate elements, the sole of the article forms an integral element with one element of the support.

[0114] In another embodiment, the article has a set of displacement devices, the set of displacement devices comprising a first displacement device and a second displacement device interconnected by a damping system, the damping system extending longitudinally between the first displacement device and the second displacement device.

[0115] The displacement device here can be a float, a wheel, a pulley or any other element suitable for the type of article. For example, the first displacement device is installed along the longitudinal portion of the damping system, corresponding to the first end of the damping system leaf spring, and the second displacement device is installed along the longitudinal portion of the damping system, corresponding to the second end of the damping system leaf spring.

[0116] Preferably, the article has a main body assembled with a central portion of the damping system.

[0117] Here, it can be seen that the main body of the object and the displacement device assembly are respectively assembled with the damping system in a relative manner along an almost vertical axis, the object is located in the center of the damping system, and the displacement devices are arranged on both sides thereof to ensure its stability. In other words, the damping system is located between the main body of the object and the displacement device.

[0118] Preferably, the body and the central portion are assembled together so that the damping system can rotate relative to the body along a substantially vertical axis.

[0119] It is known here that rotation can adjust the direction of the damping system and, by extension, the direction of the displacement device relative to the body. For example, such rotation can be achieved by using methods known to those skilled in the art to achieve directional control.

[0120] In a particular embodiment, the article comprises a plurality of displacement device assemblies and accommodates a plurality of damping systems, each damping system being respectively combined with a displacement device assembly and enabling assembly of a first displacement device and a second displacement device in the displacement device assembly.

[0121] It can be seen here that such a design can increase the stability of bulky objects, and can even be combined with the previous embodiments to achieve more complex movements. For example, an object includes two displacement device components, a total of four components, which are connected in pairs through two independent damping systems, each damping system forming a column of the object, and one damping system is assembled with the main body of the object so that it can rotate, thereby ensuring the movement of the object.

[0122] In another embodiment, the object receives the damping system via at least one hinge and / or at least one double hinge, in particular a double hinge with a spring and adjustable tension.

[0123] Therefore, it can be seen that such a component can enable the main body and / or the displacement device to rotate freely along the axis relative to the damping system, thereby reducing the pitch or left and right swing of the object during use, and in particular can improve the stability of water vehicles in waves or small sleds in changes in the height of terrain and / or snow.

[0124] Thus, through the various functional and structural features described above, the applicant has proposed a simplified, compact damping system, which can be installed in footwear in particular to cooperate with walking movements without restricting the user's mobility.

[0150] The following will be combined with the attached Figures 1 to 24 The utility model is described. In the following description, the same elements are identified by the same numbers.

[0151] As mentioned in the introduction, existing damping system solutions cannot be integrated into footwear without hindering the walking movement.

[0152] One of the purposes of the present invention is to integrate a damping system into footwear in a manner that is ergonomic and adaptable to walking, running and jumping movements.

[0153] This is possible in the example described below which considers an article of footwear housing a damping system.

[0154] It should be noted here that this example is not restrictive and the present invention can also be applied to integrate the damping system into various items, such as saddles or vehicle suspension devices.

[0155] according to Figures 9 to 11 and Fig.14 In the example shown, the damping system 100 developed by the present invention is combined with an article 200 (here, a footwear 200). According to other examples, the damping system 100 is combined with another article 200, in particular Fig. 22 and Fig.23 The combination of the water vehicle and the damping system on display, and Fig.24 The combination of the sled-like article and the damping system is shown. In order to bear the weight of the user of the article 200, the damping system 100 is particularly combined with the sole 210 of the article 200, and the weight of the user is initially borne by the sole 210. The damping system 100 can be specially designed to be combined with the sole 210, for example, to be integrated in the at least partially hollow sole 210 ( Fig.10 ), or it can be designed as a model combined with various footwear, or more generally as a basic model suitable for multiple articles 200. Of course, the damping system 100 can also be specially designed for combination with a specific article 200 or article type, for example, the size of the damping system 100 is determined according to the proportions of the article 200 or the proportions of a standard type of article, such as the proportions of saddles. Fig.11 In the example shown, the damping system 100 is sized to be removably mountable within a closed article 200 (e.g., a soft boot-type footwear having a deformable sole 210), the damping system 100 being superimposed on the sole 210 of the article 200, which itself may be covered with an insole 230.

[0156] according to Fig.14 As another example, damping system 100 is sized to be integrated into an article (e.g., one or more rows of wheels that translate through rotational engagement with an article of footwear, or one or more sets of shoes that enable the article of footwear to slide on ice, such as a set of roller skates) equipped with displacement device assemblies 241, 242. Displacement device assemblies 241, 242 include first displacement devices 241 and second displacement devices 242, with damping system extending longitudinally between first displacement devices 241 and second displacement devices 242, so that they can be assembled together and assembled with body 250 of article 200.

[0157] according to Fig. 22 As another example, multiple damping systems 100, 100' are sized to be integrated into an article 200 equipped with multiple displacement device assemblies 241, 242, 241', 242' (e.g., one or more floats or skis) to enable the article 200 to move in a water or snow environment and adapt to different water levels or snow slopes. Each pair of displacement devices 241, 242 and 241', 242' forms a column of the article 200. For example, one of the damping systems 100, 100' is assembled with the body 250 so that it can rotate along a substantially vertical axis with the body 250 to form an orientation of the article 200.

[0158] In the same example, the article 200 accommodates multiple damping systems 100, 100' through double hinges 261, 262, 263, 261', 262', 263', especially tension-adjustable double-force spring hinges, thereby allowing the main body 250, the damping system 100, 100' and the displacement device 241, 242, 241', 242' to rotate independently along a given horizontal axis, thereby slowing down the pitch or left-right shaking of the article 200. Fig.24 In the example shown, the article 250 accommodates the damping system 100, 100' via similar double hinges 263, 263', regardless of whether the article 200 is combined with a displacement device, for example the damping system 100, 100' can be fixed directly to the floor.

[0159] according to Fig.23 In one variant shown, the article 200 is equipped with a plurality of integrated displacement means 243, 243', each of which is individually connected to the body 250 of the article 200 via a separate damping system 100, 100'. In a particular example, the integrated displacement means are "foils", also called support wings, of a hydrofoil-type article 200, the damping systems 100, 100' enabling them to adjust their movement according to the waves of the water environment. According to another variant, the hydrofoil-type article 200 is equipped with a plurality of damping systems 100, 100' acting directly as "foils", i.e. in direct contact with the water environment, without passing through displacement means.

[0160] according to Figure 1 and Figure 2 In the example shown, the damping system 100 includes a leaf spring 120 having a first end 121 and a second end 122. Advantageously, the leaf spring 120 is arc-shaped between the two ends 121, 122, and can be elastically deformed by moving the two ends 121, 122 closer to or farther from each other, that is, by changing the curvature of the arc of the leaf spring 120.

[0161] In the same example, the first end 121 of the leaf spring 120 is assembled with the rigid support 110 via a first assembly device (e.g., via a hinge 131 assembled with the first end 121 and the support 110), and allows the first end 121 and the support 110 to rotate along a first axis defined by the hinge 131.

[0162] According to the basic concept of the present invention, the leaf spring 120 and the support 110 are assembled together through the hinge 131 and the first end 121, so that the arc leaf spring 120 extends along the support 110 in a convex (or raised) trajectory, and the second end 122 contacts the receiving surface 111 of the support 110, and the receiving surface 111 extends along a plane. For example, the support 110 itself is flat, or its flat receiving surface 111 is in contact with a suspension device 112 (such as a suspension device 112 for an article 200) Figure 8 The surfaces of the suspension device 112) are opposite to each other.

[0163] When the leaf spring 120 is compressed and / or relaxed, for example, Fig. 9 , 10 When the user of the article 200 in FIG. 11 presses the article 200, the article 200 transfers the weight of the user to the damping system 100, so that the first end 121 rotates relative to the support 110 along the first axis determined by the hinge 131, and the second end 122 in contact with the receiving surface 111 moves along the receiving surface 111, for example, along a second axis perpendicular to the first axis and located in the plane of the receiving surface 111. The restoring force of the leaf spring 120 cooperates with the relaxation movement of the leaf spring at the same time and is transferred to the article 200 and then to the user, thereby generating a rebound.

[0164] exist Fig. 9 , Fig.10 and Fig.11 In a specific design suitable for combining the system 100 with footwear 200 for a user to walk on, the first assembly device is arranged along the heel 220 of the footwear, and the leaf spring 120 extends toward the front end of the footwear, so that when the user's foot moves from the heel, the first end 121 rotates with it, and the second end 122 slides toward the toe before forming its posture. When the user's foot is lifted, the restoring force of the leaf spring 120 is mainly transmitted through the first end 121 along the body of the support 110 and the heel 220, while the second end 122 is free. Therefore, most of the rebound is generated with the forward movement of the user's foot.

[0165] In order to further assist the user in walking and approach the normal use state of the footwear, we also prepare an auxiliary damping device, which includes a sole replica 172 arranged along the surface of the system 100 that contacts the ground and adhered to the ground. Figure 8 and Fig. 9In the example shown in FIG. 1 , the sole replica 172 is arranged along the outer side of the leaf spring 120 .

[0166] Obviously, the arrangement of the system 100 can also be adjusted according to the expected gait of the user of the footwear or the expected use of the article 200 associated with the system 100. Thus, the system 100 can be connected to the sole 210 of the article 200 via the support 110 or the leaf spring 120, and the first mounting device is oriented along one end of the article 200 to match the expected movement. For example, a footwear includes two damping systems 100, a first system arranged along the heel and a second system arranged along the toe, so as to facilitate the placement of the foot along the heel and the toe. In addition, according to Fig.10 According to the example in , an article 200 is also prepared, which includes an at least partially hollow sole 210, the sole 210 has an upper wall and a lower wall, the system 100 is integrated between the two walls of the sole 210, and is arranged according to the design so that the support 110 is fixed and / or in contact with the upper wall or the lower wall, and the leaf spring 120 is fixed and / or in contact with the wall opposite to the support 110 along its middle part. In other words, the article 200 has a double-layer sole, including an upper sole forming the upper wall and a lower sole forming the lower wall, and the system 100 is arranged between the upper sole and the lower sole.

[0167] In addition to arranging the first assembly device, various methods of implementing the first assembly device between the support 110 and the first end 121 are prepared, depending on the ease of manufacturing, the compactness of the system 100, the expected wear of the first assembly device, the rotational freedom of the first end 121 relative to the support 110, and even the expected deformation amplitude of the leaf spring 120, such as Figures 4 to 7 , Fig.10 , Fig.11 , Fig. 20 and Fig.21 As shown, the block 132 ( Figure 4 and 5 ), the half hinge 133 (combined with the first rod 134) Figure 6 )、screw nut assembly 135( Figure 7 ), simple bonding means 136 ( Fig.10 and Fig.11 ), or an assembly consisting of a first rod or a movable pin 138, which is assembled with the first end 121 and has at least one hole 139 disposed on the support 110 to allow the first rod or pin 138 to translate ( Fig. 20 , 21 Depending on the design, the first rod or pin 138 may be inserted into the opening of the first end 121 ( Fig.21), or the first rod and the first end 121 form an integral element and correspond to the pin extending from the first end. The present invention also includes any other variants of the first assembly device known to professionals in the relevant technical field that can combine the leaf spring 120 and the support member 110 and ensure the above-mentioned movement.

[0168] While the leaf spring 120 is elastic, the support member 110 is rigid, that is, it can resist deformation, especially deformation along the force axis of the leaf spring 120, so that relative movement between the leaf spring 120 and the support member 110 is possible. For example, the support member 110 is made of a material with a certain rigidity or a specific structure (such as a honeycomb core) to increase its ability to resist deformation along the force axis of the leaf spring 120. Figure 2 In the example in FIG. 1 , a bearing plate 171 is provided between the second end 122 and the support member 110 to improve the deformation resistance and wear resistance of the support member 110 .

[0169] according to Figure 6 , Figure 7 , Fig.10 , Fig.11 and Figures 19 to 21 In a particular example shown, the support 110 has a U-shaped cross section, which greatly improves its resistance to deformation while reducing weight and thickness, making the implementation of the damping system 100 more ergonomic.

[0170] Advantageously, the U-shaped cross section forms a groove with the receiving surface 111, in which the second end 122 moves. Thus, depending on the relative widths of the groove and the second end 122, the movement of the second end 122 along the receiving surface 111 can be guided more or less precisely. Thus, the U-shaped cross section can guide the translation of the second end 122 relative to the receiving surface 111. Fig.19In the particular example shown, the first part 191a has a U-shaped cross section along the first distal portion, and the first part 191a is assembled with the support 110 by means of a first pin 192a, so that the U-shaped cross section is opposite to the groove, that is, the U-shaped cross section closes the groove along the length occupied by the distal portion. This design makes it possible to make the support 110 more rigid by preventing the side separation of the support 110 when subjected to torsion while keeping the weight of the support 110 light. Advantageously, the first pin passes through the support 110 and the first part 191a along the proximal end of the first part 191a, so that the assembly of the first part 191a and the support 110 is open for the insertion of the first end 121. The first end 121 is then located between the first pin 192a and the first distal end, so that the first part 191a and the first pin 192a at least partially form a first assembly device. The position of the first end 121 can be further locked by inserting a removable pin 140 disposed between the first end 121 and the first distal portion so that the damping system 100 can be disassembled by removing the pin 140 and the first end 121 while leaving clearance and allowing the first end 121 to rotate along the first axis.

[0171] In the same example, the second component 191b has a U-shaped cross-section along the second distal portion and is assembled with the support 110 along the second proximal portion by at least one second pin 192b (e.g., multiple pins) to provide additional security and prevent the second component 191b from rotating relative to the support 110. Then, in a similar manner to the first end 121, the second end 122 is inserted between the second pin 192b and the second distal end, for example, to increase the longitudinal gap to facilitate the movement of the second end 122 along the receiving surface 111 of the support 110.

[0172] It can be seen that Fig.19 The example shown has a substantially symmetrical design. Of course, those skilled in the art may also use different methods to utilize the groove formed by the support member 110 to make an asymmetrical design according to the power required between the first end 121 and the second end 122 .

[0173] According to a design variant, further translation guides can also be used instead of or in addition to the U-shaped cross section, referred to as first guides. Figure 2 , Figure 8 and Fig. 9In the example shown, two side guides 161 are assembled with the support member 110 and arranged on both sides of the receiving surface 111. For example, the side guides 161 are arranged only along the portion of the support member 110 corresponding to the longitudinal displacement interval of the second end 122, and can be assembled with the bearing plate 171 arranged along the same longitudinal interval. Advantageously, the side guides 161 extend forward beyond the support member 110 and are made of a rubber-like elastic material to absorb the impact when the support member 110 contacts another rigid component, such as Fig. 9 The midsole 200 is impacted when it comes into contact with the ground while tilting forward.

[0174] according to Figures 4 to 7 and Figure 20 to Figure 22 In another example shown, the support member 110 has a second rod 162a, 162b assembled with the second end 122 and at least one hole 163a, 163b. Then, the at least one hole 163a, 163b receives the second rod 162a, 162b and ensures its translation along the at least one hole 163a, 163b. The movement of the second end 122 is limited by the movement of the second rod 162a, 162b along the at least one hole 163a, 163b. The second rod 162a, 162b may be Fig.21 Removable pin shown in .

[0175] exist Figure 4 and Figure 5 In the specific design shown, a single hole 163a is opened along the receiving surface 111 and passes through the support 110, and the second rod 162a extends along a third axis perpendicular to the plane of the receiving surface. For example, the second end 122 has a hole 122a complementary to the second rod 162a for its assembly.

[0176] according to Figure 6 , Figure 7 and Figure 20 to Figure 23 In another design shown, there are two symmetrical holes 163b on the side edge of the support member 110 (such as the side edge of the groove formed by the U-shaped cross section of the support member or the side guide member 161 assembled with the support member 110). In this way, the second rod 162b extends between the two holes 163b, for example, extending parallel to the first axis, and the second end 122 includes a half hinge for receiving the second rod 162b, or directly has an opening for the second rod 162b to be inserted ( Fig.21 ).

[0177] In this way, the design of the first guide means can be adapted to the dimensions of the support member 110, thereby ensuring that the second end 122 moves along the receiving surface 111. Figures 4 to 7 It can also be seen in FIG. 1 that certain solutions can also be used to keep the second end 122 in contact with the receiving surface 111 while only allowing longitudinal movement between the two elements.

[0178] According to a variant, a retaining device independent of the above-mentioned device is used to prevent the second end 122 from falling off the receiving surface 111. The retaining device thus limits the movement of the second end 122 in the plane of the receiving surface.

[0179] according to Fig.10 In the first example shown, the support 110 and the leaf spring 120 are contained in a housing that defines the maximum relaxed volume of the leaf spring 120, for example, a housing defined by the sole 210 in a compact connection design of the article 200 and the system 100, or a housing that can be adapted to the sole 210, for example, including the connection device 112 ( Figure 8 ) or other housing that enables it to be combined with the article 200. Advantageously, the housing is semi-rigid or flexible, capable of contracting when the leaf spring 120 is compressed and extending when the leaf spring 120 is relaxed, so as not to hinder the operation of the system 100 and to keep the leaf spring 120 from rebounding, while determining the maximum volume that the housing can extend and the leaf spring can relax.

[0180] according to Figures 1 to 3 , Figure 8 and Fig. 9 In another example shown, there is a first elastic reinforcement member 141 assembled with the middle portion of the support member 110 and the leaf spring 120, such as a spring assembled between the support member 110 and the leaf spring 120 or a deformable elastic body surrounding the support member 110 and the leaf spring 120. The first elastic reinforcement member 141 then generates a force that causes the leaf spring 120 to be pressed against the support member 110. For example, the exact position of the first elastic reinforcement member 141 can be adjusted along the support member 110 and the leaf spring 120 to prevent the second end 122 from falling off with minimal force. The first elastic reinforcement member 141 can also be adjusted to provide less resistance to the relaxation of the leaf spring 120 within a specified angle range, or to promote or guide the relaxation of the leaf spring 120 to generate a larger rebound force (for example, in a manner that promotes force transmission between the first end 121 and the support member 110).

[0181] according to Figure 3In the example shown, in addition to the first elastic reinforcement 141, there is also a second elastic reinforcement 181, which can balance the forces generated by the leaf spring 120 and the first elastic reinforcement 141. In the same example, the second elastic reinforcement 181 extends longitudinally and is assembled with the first end 121 and the second end 122. Obviously, according to the respective designs of the leaf spring 120 and the second elastic reinforcement 181, especially the configuration when static, the second elastic reinforcement 181 may prevent the first end 121 and the second end 122 from moving away, thereby preventing the compression of the leaf spring 120 and increasing the rebound force generated by its relaxation, or conversely, the second elastic reinforcement 181 may also prevent the two ends 121, 122 of the leaf spring 120 from approaching, thereby preventing the leaf spring 120 from relaxing, so as to promote the compression of the leaf spring 120 and limit the rebound force, so that the system 100 can adapt to daily use.

[0182] Of course, in order to limit the losses and avoid oversizing of the system 100, and in particular of the leaf spring 120 and any first and second elastic reinforcements 141, 181, a friction-reducing device is also provided between the second end 122 and the receiving surface 111. In this way, the second end 122 is made to move as easily as possible during the compression and / or relaxation of the leaf spring 120, by limiting the influence of any forces generated by non-elastic elements.

[0183] According to a variant embodiment, at least one roller 151 is provided between the second end 122 and the receiving surface 111, so that the at least one roller 151 can ensure contact and cooperate with the translational movement of the second end 122 by rotation. In particular, this design makes it possible to reduce the friction along an axis determined by the direction of the at least one roller 151 (such as along the above-mentioned second axis). Figures 1 to 3 In the example shown, a bearing assembly using at least one roller 151 is used, which is assembled with the second end 122 and contacts the receiving surface 111. Of course, this design can also be adjusted, and at least one roller 151 assembled with the receiving surface 111 can also be prepared, and the second end 122 contacts at least one roller 151 and moves relative to the latter, for example, a group of rollers 151 are arranged at intervals along the longitudinal movement of the second end 122 on the receiving surface 111. According to another design, in order to limit the movement of the second end 122 according to the example of the first translation guide device mentioned above, or in order to bring the second end 122 close to the support 110, the receiving surface 111 has a groove for receiving at least one roller 151.

[0184] According to another variant, the damping system 100 comprises an anti-stick coating 152, which is arranged between the second end 122 and the receiving surface 111, for example, on the receiving surface 111 ( Figure 5), on the second end 122 or on any device as an intermediary. In particular, this design is easily adapted to any embodiment of the system 100 and can reduce the friction on the plane of the receiving surface 111 in all directions without affecting the volume or weight of the system 100.

[0185] according to Figures 12 to 18 In another variant shown, the support 110 comprises a frame 113 having a U-shaped cross section and a sliding member 114 having a cross section that is at least partially rectangular, a first assembly device (such as a hinge 131) is used to assemble the first end 121 with the frame 113, and the leaf spring 120 is also assembled with the sliding member 114 along its second end 122 through a second assembly device (such as hinges 137a, 137b assembled with the second end 122 and the sliding member 114), and allows the second end 122 and the sliding member 114 to rotate along a fourth axis determined by the hinges 137a, 137b. According to this design, the sliding member 114 has a receiving surface 111, the second end 122 is in contact with the receiving surface 111, and the movement of the second end 122 on the plane of the receiving surface 111 is transmitted to the sliding member 114.

[0186] according to Fig.18 In the example of the embodiment of the invention, the frame 113 of the support 110 is combined with the base 210 of the article 200, thereby limiting the total number of components and achieving a joint design of the article 200 and the damping system 100. Of course, in addition to the design of the support implemented with several elements, a variant is also designed in which the support 110 is completely combined with the sole 210 of the article 200. Similar to the first assembly device, there are various means for implementing the second assembly device between the second end 122 and the sliding part 114, which can be selected from the aforementioned list of assembly devices known to professionals in the relevant technical field, which mainly include a freely deformable block made of elastic material, a semi-hinge combined with an element forming a pivot connection, a screw-nut assembly or a simple bonding method. The second assembly device can be selected together with the first assembly device, thereby having similar characteristics, or it can be selected separately according to the assembly constraints of the frame 113 and the first end 121 and the sliding part 114 and the second end 122.

[0187] In the same variant, the frame 113 and the sliding member 114 fit together to form a translation guide, so that the movement of the second end 122 is accompanied by the translation of the sliding member 114 relative to the frame 113. Advantageously, the U-shaped and rectangular cross section extends from the face opposite to the receiving face 111, so that the leaf spring 120 can be compressed to the extreme position against the receiving face 111 without colliding with the rectangular cross section of the frame 113.

[0188] Combining the movement of the second end 122 with the movement of the sliding member 114 along the frame 113 can in particular laterally stiffen the leaf spring 120 by limiting the movement and twisting of the leaf spring 120 within the range of movement of the sliding member 114. This significantly reduces the risk of twisting of the leaf spring 120 outside of the compression and relaxation movement.

[0189] according to Figure 12 to Figure 14 In the first design shown, the translation guide is completely assembled from a frame 113 and a sliding part 114, which have complementary shapes and / or negligible play between the parts. Figures 15 to 17 In the second design shown, the second translation guide device is used to guide the sliding member 114 relative to the frame 113, and further to guide the second end 122 relative to the support member 110. The second guide device can also limit the range of motion of the sliding member 114, especially to keep it engaged with the frame 113. For example, this second guide device includes a guide member 164 assembled with the sliding member 114, and at least one hole 165 on the frame for receiving the guide member 164, so that the guide member 164 is limited when translating along at least one hole 165. Fig.15 As shown, such a design can also combine the second assembly device and the second guide device together to make the design more concise and compact, and the guide member 164 is also assembled with the hinges 137a, 137b so as to lock the second end 122 on the sliding member 114. For example, such a guide member 164 can be a detachable assembly screw that can connect the second end 122, the sliding member 114 and the hole 165, or a pin or top extending from the second end 122 or the hinges 137a, 137b and engaging with the hole 165 to lock the sliding member 114. Of course, there is another design in which the second end 122 is connected to the sliding member 114 through the second assembly device, and the sliding member 114 is guided relative to the frame 113 by a second guide device different from the second assembly device (such as two holes included in the side edge of the frame 113 and a rod extending between the two holes and connected to the sliding member 114). In particular, this design allows the second assembly device and the second guide device to be independently selected to better meet the respective constraints.

[0190] according to Figure 12 to Figure 14 In the variant shown, the sliding member 114 comprises a first portion 116 having a rectangular cross section and a second portion 117 having a U-shaped cross section. Fig.14In the example shown, this design makes it possible to combine the damping system 100 with an article 200 comprising a plurality of independent devices, for example, a body 250 assembled with the central part of the damping system 100 (here the central part of the leaf spring 120) and the front and rear displacement devices 241, 242, arranged on both sides of the support 110 formed by the frame 113 and the sliding member 114, while using the U-shaped cross section to fix the independent devices in a compact manner. By arranging the front displacement device 241 at the first end and the rear displacement device 242 at the second end, the stability of the article 200 is maximized, while concealing the height occupied by the first part 116.

[0191] In order to restrict any rotation of the partially opened first portion 116 in the frame 113, or more generally, to restrict any rotation of the sliding member 114 in the frame 113 when the sliding member 114 is fitted in the frame 113, a guide member 115 having a U-shaped or V-shaped cross section, i.e., a right-angle member, is prepared. The guide member 115 is assembled with the frame 113 so as to prevent the sliding member 114 from moving along an axis perpendicular to the second axis when the leaf spring 120 is compressed and / or relaxed, and further prevent any rotational movement beyond a predetermined gap. In other words, the sliding member 114 is installed between the frame 113 and the guide member 115 and can slide between these two elements.

[0192] like Fig.13 As shown, the first part 116 and the second part 117 are made of two independent components and then assembled into the sliding part 114. For example, the cross-section of the second part 117 is the same as the cross-section of the frame 113, and the receiving surface 111 defined by the second part 117 extends on the same plane as one surface of the frame 113, so that the structure of the support 110 can be balanced to receive the leaf spring 120 and / or the object 200.

[0193] according to Figures 15 to 17 In another variant shown, the sliding member 114 is engaged with the frame 113, thereby avoiding the risk of the sliding member 114 rotating beyond the assembly gap and simplifying the design of the sliding member 114. In addition, a variety of designs are prepared, which can adjust the geometry of the damping system according to the assembly of the damping system and the object 200, and maintain the compactness of the object 200 by installing the damping system 100 along the inner side of the U-shaped cross section of the frame 113. In particular, in the first design, the sliding member 114 is arranged on the longitudinal extension of the second end 122 ( Fig.15 ), thereby maximizing the free length of the frame 113 that is not hindered by the sliding member 114, thus increasing the space for assembling the article 200 and / or the individual parts of the article 200 (in particular the displacement device 240 forming an integral element) Fig.16In another design, the length of the damping system can be reduced to the length of the leaf spring 120 in the maximum compression position, and the sliding member 114 is embedded in the frame 113, and its longitudinal part merges with the second end 122 ( Fig.17 ), that is, the sliding member 114 does not extend beyond the frame 113 when it is required to contact the second end 112. Obviously, the positioning option of the sliding member 114 is combined with the positioning option of the second assembly device, for example, the second assembly device can be a hinge 137a, 137b that alternately presents an acute angle (137a) or an obtuse angle (137b).

[0194] Thus, it can be seen here that the present invention provides a damping system for articles (such as footwear) that can absorb shock and generate rebound propulsion force, while being more compact than existing solutions and allowing more movement variations. The damping system is particularly suitable for combination with footwear products to cooperate with walking, running and even jumping movements, but can naturally also be integrated into various products that utilize compact shock absorption, such as suspension systems, saddles or bedding, and / or products that simulate similar movements, such as bicycle or balance bike pedals or prosthetic or artificial limbs.
