Description

Technical field

[0001] The present invention relates to the field of mounting and supporting mobile devices and relates in particular to a flexible fastening device for portable mobile devices on the body.

[0002] The device is suitable for various wearing scenarios, in particular for attachment to the upper arm, thigh or lower leg of a user in order to display movement data or provide visual information while being worn. State of the art

[0003] Existing mounts and fastening devices for mobile devices are predominantly made of hard materials such as plastic or metal and typically include mechanical clamping structures, slots or rigid support plates, which mainly serve to mount mobile devices to bicycle handlebars, steering head parts or other fixed frame components.

[0004] Such devices generally rely on rigid structures for positioning and support, have a complex structural hierarchy, and are relatively heavy overall.

[0005] In certain applications, such as recumbent bicycles, wheelchairs, rehabilitation equipment or sporting activities, it is often difficult or unsuitable for the user to find a suitable mounting surface for the aforementioned rigid brackets, or the use of bulky and heavy brackets is impractical during the activity.

[0006] Therefore, in these scenarios, users often prefer to wear mobile devices directly on their bodies or attach them to body parts in order to conveniently read navigation information, movement data, or instructions.

[0007] To meet these requirements, several solutions have already been proposed that use flexible structures such as straps or elastic elements to fix mobile devices to the body.

[0008] However, these devices often still rely on rigid support plates or connecting elements made of plastic or metal to ensure stability.

[0009] Such rigid components not only lead to a complex structure and higher weight, but also reduce carrying comfort and ease of handling when storing.

[0010] Furthermore, body-worn devices are characterized by their high portability and intermittent use.

[0011] When the user finishes the activity or is not wearing the device, it usually needs to be removed and stored in small spaces such as pockets or bags. Devices with rigid components are difficult to store due to their fixed size and lack of foldability or rollability.

[0012] There is therefore a significant need for a lighter, softer and particularly space-saving fastening device.

[0013] However, if a rigid support structure is completely dispensed with and only flexible elements are used, significant stability problems arise: Due to the lack of a rigid support plate, elastic elements under tension tend to be subjected to uneven stress, which can cause the mobile device to easily tilt (e.g., lateral displacement or rotation) or slip during movement.

[0014] Therefore, the current state of the art lacks a body-worn attachment device that is completely flexible, lightweight and compact, while simultaneously holding the mobile device stably without requiring a rigid support plate. Description of the invention (A) Object of the invention

[0015] The aim of the present invention is to provide a flexible fastening device for portable mobile devices (4) on the body, by which the mobile device (4) can maintain its intended position and orientation even in the absence of a rigid support plate and with a small number of fastening points.

[0016] This achieves a stable, oriented fixation that simultaneously reduces deviation and does not impair the viewing area of ​​the display. (B)Technical solution

[0017] The present invention relates to a flexible attachment device for portable mobile devices (4) on the body, comprising: 1. A flexible band (1) for attachment to the body part (5) of the user; 2. At least one elastic element (2) that enables elastic fixation of the mobile device (4); 3. At least two guide elements (3) arranged on the flexible band (1).

[0018] In the invention, the guide elements (3) are structural units that are arranged on the flexible band (1) and serve to limit and guide the flow path of the elastic element (2).

[0019] Its function is that when tensioning the elastic element (2) to fix the mobile device (4) it is guided along a predetermined path over the mobile device (4), thereby creating a defined force path.

[0020] The structure can guide and separate both a single path of an elastic element (2) and multiple paths simultaneously.

[0021] The core mechanism consists in the fact that the guide elements (3) physically restrict the stress distribution of the elastic element (2) by means of a predetermined arrangement, so that the resulting force exerted by the elastic element (2) on the mobile device (4) in the tensioned state acts essentially along the diagonal of the mobile device (4) in its intended orientation position.

[0022] This force vector guidance generates a corrective moment that effectively prevents deviation in the posture of the mobile device (4) during carrying.

[0023] In a specific embodiment, the connection between the guide elements (3) and the elastic elements (2) can be either rigid (e.g. by sewing, gluing or molded part manufacturing) or detachable (e.g. by hook and loop fasteners, buckles, hinged straps or openable ring structures) to allow separation or rearrangement as required.

[0024] As long as the guide elements (3) ensure position limitation and path guidance of the elastic element (2) in the operating state, they fall within the scope of protection of the invention. (C) Advantages of the invention

[0025] Compared to the prior art, the present invention has at least the following advantages: 1. The guide elements (3) arranged on the flexible band (1) geometrically guide and limit the tension distribution of the elastic element (2). This allows the mobile device (4) to be stably fixed, even without a rigid support plate, and effectively secures its position against deviations. 2. The device is made entirely of flexible materials, has a simple structure and is lightweight, comfortable to wear, and highly adaptable. It can be securely attached to the user's upper arm, thigh, or lower leg and is suitable for various dynamic scenarios, such as cycling, rehabilitation exercises, or fitness activities. 3. The device contains no rigid frames. When not in use, it can be completely rolled up or folded and reduced to a minimal volume, allowing it to be stored directly in pockets or bags, which greatly facilitates portability and storage. 4. By guiding and limiting the stress distribution of the elastic elements (2) using the guide elements (3), deviations in the posture of the mobile device (4) are effectively suppressed, even without a rigid support structure. This ensures stability while simultaneously reducing structural complexity and manufacturing costs. List of drawings Fig. 1: Entire device worn on the body (using the leg as an example).

Implementation example (A) Basic structure of the device

[0026] As in Fig. As shown in Figure 2, the device comprises a flexible band (1), an elastic element (2) and several guide elements (3).

[0027] Flexible band (1): Made of fabric, elastic composite material or other flexible materials and designed to be placed around and fastened around the body part (5) of the user.

[0028] Elastic element (2): Made of silicone, elastic fabric or rubber, as in Fig. 3 and Fig. 5-2 shown, for the diagonal enclosure of the mobile device (4) via D1 or D2.

[0029] In other embodiments, the elastic element can consist of several independent segments.

[0030] Guide elements (3): As in Fig. As shown in Figure 2, two guide elements (3) are arranged in the width direction of the band, near the upper and lower edges of the band, in an obliquely offset arrangement. They serve to guide and limit the tensile path of the elastic element (2). The elastic element (2) can be attached to the guide elements (3) by hook and loop fasteners, sewing, gluing, or other suitable methods. In further embodiments, four or more guide elements can be provided. (B) Function of the skewed arrangement of the guide elements

[0031] As in Fig. 3 and Fig. As shown in Figure 4, the mobile device (4) is in an inclined position and tends to shift laterally during the movement of the user if it is fixed only by a single elastic element (2) and no guide elements (3) are provided.

[0032] The cause of this deviation is that the elastic element (2), without guide elements (3), tends to contract towards the geometric center of the mobile device (4) under tension. The two contact areas between the elastic element and the edges of the flexible band (1) together generate a resultant moment that causes a tilting movement of the mobile device (4) relative to the band (1).

[0033] The diagonally offset arrangement of the guide elements (3) on the flexible band (1) physically restricts the pulling path of the elastic element (2).

[0034] As in Fig. As shown in Figure 4, the arrows F schematically illustrate the directions of the constraint forces at the points where the guide elements act on the elastic element (dashed squares). These forces are absorbed by the guide elements during operation (Figure 3, see Figure 4). Fig. 5) exerted on the elastic element to counteract the posture deviation of the mobile device (4). The arrows F serve only to illustrate the guidance of the force path through the guide elements (3) and do not represent actual, independent force applicators or exact forces.

[0035] Under this constraint, the direction of the resulting force of the elastic element (2) changes, such that its vector essentially runs along the diagonal of the mobile device (4) in its intended orientation position. This reduces or eliminates the initially divergent moments, and the mobile device (4) remains stably perpendicular to the flexible band (1) while being worn.

[0036] The intended orientation position of the mobile device (4) refers to the state in which its longitudinal center is essentially parallel to the width of the flexible band (1), so that the display surface of the mobile device (4) is almost perpendicular to the band (1).

[0037] Furthermore, the guide elements (3) limit the lateral displacement of the elastic element (2) relative to the band during wear, thereby reducing the degrees of freedom of lateral deviation of the mobile device (4).

[0038] In the event of external disturbances, the elastic element (2) under the guidance of the guide elements (3) generates a force component that returns the mobile device (4) to the intended position, thereby effectively suppressing lateral wobble.

[0039] As in Fig. As shown in Figure 7, the present structure significantly reduces the natural deviation of the mobile device (4) during carrying and movement compared to fastening without guide elements. (C) Several specific embodiments

[0040] Design 1: Diagonally guided fixation with a single elastic element

[0041] As in Fig. As shown in Figure 5-1, in a specific embodiment two guide elements (3) are arranged in the upper right and lower left areas of the band (1) so that a single elastic element (2) is fixed diagonally along the first diagonal (D1) of the mobile device (4).

[0042] As in Fig. As shown in Figure 5-2, in a further specific embodiment the two guide elements (3) can optionally be arranged in the upper left and lower right area of ​​the band (1), so that the single elastic element (2) is fixed diagonally along the second diagonal (D2) of the mobile device (4).

[0043] Both arrangements of the guide elements (3) lead to a stable, oriented fixation of the mobile device (4) by guiding the tension profile of the elastic element (2) and represent equivalent embodiments of the invention. Design 2: Reinforced fixing with multiple guide elements

[0044] Building upon embodiment 1, as described in Fig. As shown in Figure 8, the number of guide elements (3) can be increased to four. The two upper points are arranged diagonally offset from the two lower points.

[0045] By increasing the number and staggering the arrangement of the guide elements (3), more stable stress profiles of the elastic elements (2) are created, which further improves the fixation stability of the mobile device (4).

[0046] In this embodiment, the exact arrangements of the guide elements (3) can be made in several variants, e.g. as in Fig. 8-1 and Fig. 8-2 is shown, without this deviating from the technical idea of ​​the invention. Design 3: Guided fixation with multiple independent elastic segments

[0047] Based on embodiment 2, at least two independent elastic segments can be used.

[0048] As in Fig. 9-1 and Fig. As shown in Figure 9-2, a specific embodiment comprises two independent elastic segments (2a, 2b) which are each guided by the corresponding guide elements (3).

[0049] By using several independent elastic segments (2a, 2b) and guiding them separately, different areas of the mobile device (4) can be selectively fixed without a central connecting element. Under the influence of the guiding elements (3), each elastic segment (2a, 2b) collectively forms a stable tension profile, thus ensuring stable, oriented fixation of the mobile device (4). Design 4: Double diagonal X-lock with four guide elements

[0050] Building upon embodiment 3, as in Fig. 10-1 and Fig. As shown in Figure 10-2, a double-diagonal X-fixation is provided. Two independent elastic elements (2a, 2b) fix the two diagonals (D1, D2) of the mobile device (4) and form a crossed arrangement.

[0051] In this embodiment, the two elastic elements (2a, 2b) cross symmetrically, so that balanced moments act on the mobile device (4). The upper and lower guide elements (3) therefore no longer need to be arranged at an angle, but can be aligned essentially along the longitudinal direction of the band (1).

[0052] Although the displacement is not strictly necessary, the guide elements (3) continue to stabilize the paths of the elastic elements (2a, 2b) and prevent slippage. This crossed arrangement, due to the symmetry of forces and the combined path guidance, results in higher fixation stability, especially for highly dynamic or strongly vibrating application scenarios.

[0053] Embodiment 5: Simplified double-diagonal X-fixation with two guide elements. Based on embodiment 4, as in Fig. As shown in Figure 10-3, a simplified structure is provided. The previously multiple guide elements (3) on both sides of the band (1) are each combined into a single point (3).

[0054] The two elastic elements (2a, 2b) are fixed by these two guide elements (3) and cross over each other in an X-shape along the two diagonals (D1, D2) of the mobile device (4), creating a stable and symmetrical cross-fixation.

[0055] As in embodiment 4, the two elastic elements (2a, 2b) act symmetrically, so that balanced moments act on the mobile device (4). The two guide elements (3) do not need to be offset at an angle, but can be aligned along the longitudinal direction of the band (1).

[0056] The exact position of the two points (3) in the width direction of the band can be chosen as needed, e.g., near the upper edge, lower edge, or in the middle of the band. As long as the elastic elements (2a, 2b) are guided and supported along a defined path, a stable cross-fixation of the mobile device (4) is achieved. Uniform parameter specifications

[0057] In the embodiments described above, the size and elasticity coefficient of the elastic elements (2, 2a, 2b), the width of the flexible band (1), and the spacing and guide angle of the guide elements (3) can be adapted according to the size, weight, and respective application scenarios of the mobile device (4). The invention does not restrict these parameters. (D) Way of wearing

[0058] When using the device, the flexible band (1) is first placed around the corresponding body part (5) and secured (see Fig. 1) The mobile device (4) is then placed on the designated position of the band (1), and the elastic elements (2, 2a, 2b) are stretched and arranged diagonally or crossed to fix the mobile device (4) (see right-hand figure in Fig. 7).

[0059] Since the device consists entirely of flexible materials and contains no rigid support plate, the device can be used in its unused state, as in Fig. 11 shown, can be completely rolled up or folded and brought into a particularly compact form, thereby greatly facilitating transport and storage.
