Description

Multifunctional wearable device for sliding on smooth surfaces

[0001] The present invention relates to a multifunctional wearable device for sliding on smooth surfaces, for recreational, rehabilitative, and assisted mobility use.

[0002] The invention is a device designed to bring entertainment and the experience of a wearable device into domestic environments, offering children a safe and enjoyable play option.

[0003] In general, the present invention relates to transport and play devices designed to improve the recreational and sporting experience, in particular within domestic environments, encompassing a range of devices such as elastic shoes with rebound systems, pogo sticks, training apparatuses for specific sports such as surfing and skateboarding, and devices with platforms that allow oscillating or balancing movements. Such devices may incorporate features such as helical springs, leaf springs, and rebound mechanisms, designed to enhance resilience and movement dynamics. Furthermore, special materials that promote adhesion are considered, such as hook-and-loop fastening systems, and solutions to reduce size and facilitate transport.

[0004] In particular, the present invention relates to a safe and versatile indoor wearable device, specifically intended for children. This device is conceived to provide a safe play experience, combining elements such as shock absorption mechanisms and support surfaces that allow balancing movements. The design of the wearable device may include handles and platforms for operation with both the feet and the hands, integrated with safety systems to prevent injuries during use. The invention may also provide elements to facilitate manual propulsion, similar to seatless vehicles such as non-motorized scooters. The device may incorporate innovative solutions such as lighting mechanisms or assisted propulsion devices, thereby improving the recreational experience and overall safety.

[0005] The prior art is represented by patent US20140298679A1, relating to a device that integrates springs or spacers applied to shoes or to the feet, designed to assist locomotion through a dual-orientation mechanism. This detailed description illustrates an invention relating to a spring or spacer apparatus applied to the foot or to a shoe. The apparatus allows two distinct orientations: a “downward” orientation to contact the ground during spring-assisted locomotion and an “upward” orientation for normal use of the foot or shoe. The invention includes three functionalities: a spacing or spring system, a hinge, actuator and locking sub-system, and an attachment system to the user’s foot or shoe or to the body. The hinge represents a pivot or rotation means that allows the spring or spacer to be oriented in one of two possible orientations: “downward” or “upward”. The particular orientation at any time is selected at the discretion of the user by means of an actuation means. Finally, the locking function refers to the manner in which the spring or spacer, when in the “downward” position, is held firmly in place during thrust. This apparatus provides assisted mobility and is suitable for both sporting and rehabilitative contexts, improving physical performance with a versatile and safe design.

[0006] Furthermore, the prior art is represented by patent US5002294A, relating to an invention that provides for the replacement of the traditional trucks of a skateboard with front and rear trampoline assemblies. During operation, the traditional trucks are removed from their respective positions on the mounting blocks of a conventional skateboard and are replaced by trampoline assemblies that are mounted in the same positions on the same blocks. These assemblies use telescopic elements and helical springs to allow the user to perform repeated jumps. A user standing on the upper surface of the deck of the converted board, with one foot inserted into a front strap and the other into a rear strap, lifts the board upward and moves it forward along a path by jumping into the air. When the board lands, the downward force of the user standing on the platform is applied to actuate the telescopic sleeve, compressing the spring to store energy which is then released as a restoring force to assist the next upward jump. In this manner, the user performs a series of jumps with assistance for each jump provided by recovering part of the energy stored by loading the springs at each landing. This solution offers a new approach to skateboard movement, improving jumping capability and play dynamics through the innovative use of springs for energy storage and release.

[0007] The prior art is also represented by utility model CN214436419U, relating to a wearable device designed for domestic use with advanced safety features. The wearable device comprises a flat base composed of multiple layers, which provide stability and strength. The core of the structure is a support member, consisting of a tube with an upper end and a lower end. This support member is connected to a handlebar, also having an upper end and a lower end, wherein the lower end is securely fixed to the support member to ensure safe and stable use.

[0008] The base of the wearable device is made of an elastic and flexible material, such as polyethylene foam. This choice is intended to ensure safety for both the user and the surrounding environment, since the elastic material absorbs impacts and reduces the risk of damage during use. The flexibility of the material allows the wearable device to adapt to different surfaces without compromising stability.

[0009] The handlebar is connected by connecting pins positioned at the upper end and the lower end of the handlebar. These pins, which may be made of silicone, ensure that the handlebar is securely fixed to the support member, providing additional safety and stability. A bearing device connects the upper end of the support member to the base, allowing smooth rotation. This device comprises a plate, a through hole in the upper end of the support member, a pin, and a removable cover. The bearing structure prevents the support member from sliding away from the base, ensuring safe and stable use of the wearable device.

[0010] The handlebar is fixed to the support member by means of a connector, a cap, and a quick fastening, allowing easy assembly and disassembly. This design makes the wearable device extremely practical for domestic use, where space may be limited. The support member is designed to be hollow, with an internal diameter greater than the external diameter of the handlebar. This allows the handlebar to be inserted into the support member during packaging, making the wearable device easy to transport and store. The connecting pins are designed to fit perfectly inside the support member, allowing compact and efficient packaging.

[0011] The design of the wearable device provides for the use of non-metallic and lightweight materials. The base, for example, is made of polyethylene foam, while the support member and the handlebar are made of polypropylene. This choice of materials makes the wearable device light and easy to handle, ideal for domestic use. The base of the wearable device has a flat lower surface without protruding wheels, allowing the user to perform acrobatics in indoor environments or on delicate surfaces without risk of damaging them. This feature makes it particularly suitable for domestic use, where safety and surface protection are essential.

[0012] Alternatives may be adopted in the configuration, for example with an arcuate portion of the plate protruding above the base. The structure allows rotations of the support member and the handlebar, facilitating the execution of acrobatics. The innovative concept may be implemented in various ways as technology advances. The invention is not limited to the examples described above, but may vary within the scope of the claims.

[0013] The prior art described above presents several problems that the invention in question aims to overcome. Although the existing patents offer innovative solutions for movement and play, they do not fully meet the requirements of safety, practicality, and versatility required for domestic use, especially for children. In particular, patent US 2004 / 0068832 A1, not cited in the prior art described above, describes a recreational device applied to the feet of a user in order to allow sliding indoors on carpeted surfaces. Said document discloses a wearable slide comprising a flexible sheet-like sole having a low-friction bottom surface, optionally shaped to minimise the contact area with the carpet, and secured to the user’s foot by adjustable strap members. While such a solution is suitable for recreational sliding on carpeted floors, it is specifically conceived for use on carpeted surfaces and does not address the technical requirements of controlled sliding on smooth indoor floors, nor does it provide solutions for modular friction control, impact absorption, or enhanced stability in domestic and rehabilitative environments. Similarly, patent US20140298679A1 uses springs and spacers for locomotion assistance, which may be complex and potentially dangerous in narrow domestic environments, while patent US5002294A describes jumping mechanisms with trampolines that may be dangerous if used in limited spaces and do not offer adequate protection against impacts. Although the utility model CN214436419U proposes a design suitable for indoor use, it does not fully address safety requirements with play elements that involve children in a safe and interactive manner.

[0014] The purpose of the present invention is to solve the above-mentioned problems of the prior art by providing a safe and versatile indoor wearable device for children, which offers the possibility of customizing the contact surfaces according to different types of domestic flooring, extending the adaptability of the device.

[0015] A further purpose is to actively engage children in play through visual or interactive feedback such as, for example, a braking system with LEDs, lights, arrows, and a mirror.

[0016] A further purpose is to ensure a lightweight and compact structure, facilitating transport both within individual dwellings and from one dwelling to another, as well as storage of the device within dwellings.

[0017] A further purpose is to use non-metallic and safe materials, reducing the risk of injury and minimizing the impact on the domestic environment.

[0018] A further purpose is to integrate elements that promote balance and coordination in children, improving their motor skills through play.

[0019] A further purpose is to provide a safe and versatile indoor wearable device for children, capable of providing a multifunctional mode that allows the device to be used both as a wearable device and as double skates.

[0020] The above-mentioned and other purposes and advantages of the invention, as will result from the following description, are achieved by a multifunctional wearable device for sliding on smooth surfaces, for recreational, rehabilitative, and assisted mobility use, as described in claim 1. Preferred embodiments and non-trivial variants of the present invention form the subject of the dependent claims. It is understood that all the appended claims form an integral part of the present description. It will be immediately apparent that numerous variants and modifications may be made to what is described (for example relating to shape, dimensions, arrangements, and parts with equivalent functionality) without departing from the scope of protection of the invention as set forth in the appended claims.Advantageous effects of the invention

[0021] This invention presents several advantages over existing solutions.
