ADJUSTABLE AND PORTABLE HOLDING DEVICE FOR A END DEVICE

Description

AREA OF INVENTION

[0001] The invention relates to a holding device 5 for an end device. TECHNICAL BACKGROUND

[0002] For communication, end devices, especially mobile devices such as cell phones, tablets, or similar devices, are frequently used today. The end device is generally positioned within a specific area of ​​a person's environment (usually the area around the head) to enable the meaningful display and / or reception of information. If the user wishes to perceive this information visually, the end device must be positioned within the user's accessible field of vision. Conversely, the reception of information, such as taking a photograph, may require that the position of the end device relative to the user be adjustable from a typical "display position."

[0003] US Patent 2015 / 354753 A1 discloses an adjustable media holding device that can be used hands-free and is designed to hold media of various sizes and configurations in front of the user.

[0004] US 6,764,231 B1 discloses camera mounts that help a photographer keep a camera steady during use without unduly restricting the freedom of movement of the photographer or the camera.

[0005] According to some state-of-the-art solutions, the user must hold the device in position with at least one limb (arms, legs) to position and orient it. This restricts the user's freedom of movement.

[0006] Furthermore, current technological solutions can only inadequately guarantee positional accuracy of the terminal device, especially if the user is also moving, e.g., during sports activities. In this case, the terminal device must be manually repositioned by the user. This further restricts the user's freedom of movement. SUMMARY

[0007] It is an object of the invention to eliminate or at least reduce the disadvantages of known holding devices. In particular, it is an object of the invention to be able to position and orient a terminal device in such a way that the freedom of movement of a person (user, wearer of the holding device) is increased and / or the position and orientation of a terminal device relative to the person remains essentially constant despite movement of the person.

[0008] The problem is solved according to the invention by the subject matter of the independent patent claim.

[0009] Among other things, a mounting device for an end device is provided. The end device can be a mobile device, a mobile phone, a tablet computer, a personal digital assistant, a pocket computer, a mobile data collection device, or a navigation device.

[0010] The holding device is designed to be worn by a person. The holding device comprises a first component. The first component can be a bar or a frame. The first component is shaped such that it can be supported by the shoulders and / or neck and the anterior thorax (upper body). The first component may have a curved shape. The holding device further comprises a second component connected to the first component. The second component is designed to receive (hold) a terminal device. The holding device also includes an alignment function. The alignment function is designed such that the terminal device held by the second component can be oriented and positioned essentially freely relative to the first component within a predetermined volume.The mounting device, as designed, allows the orientation and positioning of the device relative to the user within the spatial volume to be adapted to suit any application. Furthermore, the mounting device enables essentially free orientation and positioning of the device without requiring any input from the user via their limbs (arms, legs).

[0011] The first component comprises a thoracic section. The alignment mechanism also includes a first ball joint. The second component is coupled to the thoracic section of the first component via this first ball joint. The first ball joint can be locked in place. This retaining device allows for improved positioning and orientation of the end device relative to the thoracic section of the first component through the first ball joint.

[0012] The first component can be deformable, allowing its shape to be adapted to the individual human form. The first component can also be essentially rigid. In particular, the first component can be so rigid that it is essentially non-deformable (at least not within the range of normal human exertion of force).

[0013] The alignment functionality includes a second ball joint. This second ball joint is designed such that the orientation of the terminal device held by the second component is variable relative to the second component. The holding device may include a clamping element by which the terminal device is held. The orientation of the clamping element relative to the second component can be variable by means of the second ball joint. The second ball joint may be lockable. The holding device thus designed features a combination of two ball joints, so that the positioning and orientation of the terminal device can be advantageously further improved. The interacting ball joints make it advantageously possible to determine the positioning and orientation of the terminal device essentially independently of each other.

[0014] The first and / or the second ball joint can be remotely controlled.

[0015] The alignment functionality includes a telescopic rod. The telescopic rod is designed to change the position of the terminal held by the second component relative to the first component. The telescopic rod may include length adjustment, which may be lockable. For this purpose, the telescopic rod may include a locking mechanism. This holding device allows for further advantageous improvement of the terminal's positioning and orientation. The telescopic rod provides at least one translational movement by means of which the distance between the terminal held by the second component and the first component can be changed.

[0016] According to a further advantageous aspect, the telescopic rod can have only one translational degree of freedom. The telescopic rod can be configured to be adjustable only along this single translational degree of freedom. Accordingly, the telescopic rod advantageously does not provide any additional rotational degrees of freedom (besides those resulting from any ball joints that may be present). As a result, the holding device advantageously has an improved kinematic chain, so that the positioning and orientation of the terminal device are advantageously more precise.

[0017] The telescopic pole can also include an electric and / or pneumatic and / or hydraulic drive.

[0018] According to a further advantageous aspect, the first ball joint can be at least partially enclosed by a rotatable housing part. The housing part can have a cutout. The cutout in the housing part can be configured to lock the position of the telescopic rod. The position of the rotatable housing part can be locked. This means that the angle of rotation of the rotatable housing part can be locked. If the telescopic rod is oriented such that it is aligned with the cutout in the housing part, then locking the housing part also locks the orientation of the telescopic rod. The first ball joint and / or the position (angle of rotation) of the rotatable housing part and / or the orientation of the telescopic rod can be locked by means of a single locking device. The locking device can, for example, be a wing nut.The wing nut can be arranged on the housing part of the first ball joint. The holding device thus designed advantageously has an improved kinematic chain, so that the positioning and orientation of the terminal device are advantageously more precise.

[0019] The first component comprises the thoracic section and a neck section. The support device also includes a thoracic support point where the thoracic section rests on the anterior thorax (front of the chest) of the user. The support device may then include a length adjustment mechanism. This mechanism allows for a variable distance between the neck section and the thoracic support point. The support device designed in this way advantageously offers improved adaptability to the individual physique of the user. Consequently, this type of support device provides enhanced wearing comfort.

[0020] The neck section can be a neck brace.

[0021] According to a further advantageous aspect, the length adaptation mechanism can comprise at least a first and a second sub-element of the first component. The combined length of the first and second sub-elements of the first component can be variable. The combined length can be locked in place by a detent mechanism. The first and second sub-elements of the first component can be connected to each other by at least a positive locking mechanism. The holding device thus designed provides a mechanically simple but robust adaptation mechanism for advantageously adjusting the length of the first component (i.e., the distance between the thoracic support point and the neck section) to the human anatomy.

[0022] The first component comprises the thoracic section, the neck section, and a shoulder section. The length adjustment mechanism can be integrated into one of the shoulder and thoracic sections of the first component. The support device can include an additional length adjustment mechanism, which can be integrated into the other of the shoulder and thoracic sections of the first component. Advantageously, the support device thus configured can include two length adjustment mechanisms, thereby further improving its adaptability to the user's body shape.

[0023] Each or all length adjustment mechanisms may also include an electric and / or pneumatic and / or hydraulic drive.

[0024] The first component comprises the thoracic and cervical sections. The support device includes at least one chest strap. The chest strap may be detachable. One end of the chest strap can be connected to the cervical section of the first component. A second end of the chest strap can be connected to the thoracic section of the first component. The connection of the first and second ends of the chest strap to the first component may each be achieved by means of a locking mechanism. The chest strap may be designed to ensure a substantially stable position of the support device relative to the user's thorax. The support device designed in this way advantageously allows the relative position of the device to remain substantially constant to the thoracic section, even though the user may move, e.g., engage in sports activities. The support device therefore advantageously exhibits improved positional stability of the device.

[0025] The chest strap can run from the neck area, under the shoulder joint, to the thorax and / or the support element. There can also be a pair of chest straps, with one running under each shoulder joint (under each armpit). The multiple chest straps can also cross over each other in the anterior and / or posterior thorax and / or neck area. This can further improve positional stability.

[0026] The chest strap can include a textile element and / or a plastic element (rubber band, elastic band). The chest strap can include at least a portion that is elastic, allowing it to adapt to the user's body contours. This elasticity advantageously improves the positional and / or orientation stability of the support device.

[0027] According to a further advantageous aspect, the holding device can include means for sound reproduction (speakers, earphones, earbuds) and / or image reproduction (display) and / or sound recording (microphone) and / or image recording (camera, video camera). Such means can be coupled and / or connected to the terminal device. The holding device designed in this way advantageously provides enhanced functionality. For example, the holding device can include integrated headphones, thus providing the user with improved acoustics and potentially suppressed ambient noise.

[0028] According to a further advantageous aspect, the holding device can include an energy storage device. The energy storage device can be attached to the holding device. The holding device can be designed such that the energy storage device can be coupled and / or connected to the terminal device. The energy storage device can be integrated into the first component and / or arranged on it. The holding device designed in this way makes it possible to advantageously increase the charge level of the terminal device by means of the energy storage device.

[0029] According to a further advantageous aspect, the first and / or second component can have at least a partially elastic and / or anti-allergenic coating. The resulting retention device makes it possible to advantageously increase wearing comfort and / or advantageously reduce the risk of triggering an allergy. The first and / or second component can also include padding, at least in sections. The padding can be made of foam and / or cold foam and / or Temperfoam and / or leather and / or fabric and / or Alcantara. The padding can include internal magnets. The magnets can be designed to attach the padding to a portion of the first and / or second component.

[0030] According to a further advantageous aspect, at least one part (section, sub-component) of the first component and / or the second component can be made of a metallic material and / or aluminum and / or carbon and / or a bioplastic and / or a plastic. The holding device thus designed advantageously makes it possible to increase the stability of the holding device and / or to reduce its weight.

[0031] According to a further advantageous aspect, the holding device can include a tripod function. This tripod functionality can be provided by a suitable shape of the first component. The shape of the first component can be such that the tripod functionality is ensured for a holding device placed on a substantially horizontal surface. The holding device designed in this way provides enhanced functionality. For example, placing it on a table can advantageously ensure a secure positioning of the terminal device. Furthermore, it then advantageously allows more than one user to interact with the terminal device.

[0032] According to further advantageous aspects, the second component can include a gooseneck.

[0033] The thoracic section of the first component may also include a support element. This support element essentially provides a bearing surface by means of which the first component rests on the anterior thoracic region (front of the chest) of the user. The bearing surface of the support element may encompass the thoracic support point.

[0034] The second component can essentially comprise the first ball joint, the telescopic rod, the second ball joint, and the clamping part.

[0035] The alignment functionality can include the first ball joint, the telescopic rod, the second ball joint, the rotating housing part of the first ball joint, and the chest strap. Using the aforementioned components, the device can, of course, also be oriented and positioned so that it is not in the user's field of vision, but, for example, rests on a shoulder.

[0036] The support device can also be worn on the back. It can therefore also be applied and worn upside down. In this case, the support device rests on the upper part of the wearer's back (essentially on the shoulder blades and the area between them).

[0037] In the context of this application, "lockable" or "fixable" means that the relevant components exhibit such high resistance and / or friction that they can essentially maintain their orientation in the locked or fixed state and / or can only change it if a considerable force is applied. Locking or fixing the components therefore advantageously allows the terminal device to be aligned more precisely with the user's primary posture and / or line of sight and / or within the user's field of vision, and ensures positional and / or orientational stability of the set position and / or orientation.

[0038] In the context of this application, the anterior thoracic region (anterior upper body region) can refer to the forward-facing area of ​​a person's thorax, in particular including the chest, sternum, rib cage, and abdominal wall. The shoulders can refer to the area above the collarbones, adjacent to the neck. The neck can refer to the posterior region of the thorax, particularly in the area of ​​the base of the neck.

DETAILED DESCRIPTION OF THE EXECUTION EXAMPLES

[0040] Figure 1 Figure 1 shows a simplified schematic representation of the holding device 10 according to one embodiment in a side view. The holding device 10 is supported by a person 12, who is represented here by part of their torso.

[0041] The holding device 10 comprises a first component 20. The first component 20 comprises a bracket or frame 21. The first component 20 comprises a thoracic section 22, a shoulder section 23, and a neck section 24. The first component 20 includes an angle α at the junction between the thoracic section 22 and the shoulder section 23. The angle α enclosed by the thoracic section 22 and the shoulder section 23 is preferably more than 70 degrees and less than 170 degrees, more preferably more than 110 degrees and less than 150 degrees. More preferably, the enclosed angle α is substantially (135 ± 10) degrees. The first component 20 comprises a support element 25. Insofar as the holding device 10 is worn by a person 12, the first component 20 encloses the lower neck region of the person 12. The support element 25 can be integral with the thoracic section 22.The thoracic section 22 can also be separate from the support element 25 and merely attached to it in a suitable manner. Extending from the support element 25, the thoracic section 22 comprises two segments that initially run essentially parallel. With increasing distance from the support element 25, the distance between the segments increases towards the transition between the thoracic section 22 and the shoulder section 23. The thoracic section 22 can rest essentially on an anterior torso region (anterior thorax) or run essentially parallel to it at a short distance. The anterior torso region can include the chest and / or the décolletage and / or the sternum and / or the abdominal wall. The shoulder section 23 is inclined relative to the thoracic section 22 at an angle α.The shoulder section 23 comprises, starting from the transition to the thoracic section 22, two essentially parallel segments that rest on the shoulders of the person 12. Adjoining these two segments of the shoulder section 23, the first component 20 comprises a neck section 24. The neck section 24 attaches to the two segments of the shoulder section 23 and joins them in the neck region of the person 12. The neck section 24 may include a curve and / or a bend to conform to the contour of the (protruding) spine in the neck region of the person 12. The first component 20 encloses the neck of the person 12. The first component 20 may be formed essentially by one or more wires and / or one or more rods and / or one or more tubes.The material thickness (diameter) of the first component 20 is preferably more than 1 mm and less than 30 mm, further advantageously more than 4 mm and less than 8 mm.

[0042] The thoracic section 22 and / or the shoulder section 23 and / or the neck section 24 can be integral or separate from each other in pairs or as a whole.

[0043] The first component 20 further comprises a first length adaptation mechanism 40 and a second length adaptation mechanism 44. The first length adaptation mechanism 40 is located in the shoulder section 23 of the first component 20. The second length adaptation mechanism 44 is located in the thoracic section 22 of the first component 20. The first length adaptation mechanism 40 and the second length adaptation mechanism 44 are essentially identical in design. A length adaptation mechanism 40, 44 comprises a first sub-element and a second sub-element. The sub-elements can be positively connected. For example, the sub-elements can be formed by two interlocking hollow tubes. The sub-elements are slidably relative to one another in increments, so that the overall length of the respective length adaptation mechanism 40, 44, determined by the first and second sub-elements, is variable.

[0044] The first component 20 comprises a thoracic support point 25a, which is part of the support element 25. At the thoracic support point 25a, the thoracic section 22 and / or the support element 25 rests on the anterior upper body region of the person 12. The first component 20 includes a distance a between the thoracic support point 25a and the neck section 24. The distance a is variable by means of the first length adaptation mechanism 40 and the second length adaptation mechanism 44. Thus, the first component 20 can be adapted to the body shape (body contour) of the person 12 by means of the first length adaptation mechanism 40 and the second length adaptation mechanism 44.

[0045] The restraint device 10 comprises at least one chest strap 46. The chest strap 46 includes a section 46a. The section 46a comprises an elastic material (e.g., a rubber band). A first end 47 of the chest strap 46 is attached to the thorax section 22 and / or the support element 25. A second end 48 of the chest strap 46 is attached to the neck opening 24. The first and second ends 47, 48 of the chest strap 46 are each attached to the first component 20 by means of a snap-fit ​​connection. Therefore, the chest strap 46 can be removed. The chest strap 46 is passed under the upper arm of the person 12. The elasticity of the material of section 46a ensures a high degree of positional stability of the first component 20, in particular the support element 25 and / or the thorax section 22, relative to the torso of the person 12. The positional stability is even guaranteed by the chest strap 46 when the person 12 moves, e.g., when engaging in sports.

[0046] A housing 50 is attached to the support element 25. The housing 50 at least partially encloses a first ball joint 30. A telescopic rod 26 is attached to the first ball joint 30. The first ball joint 30 is configured to change the orientation and / or position of the telescopic rod 26 relative to the support element 25. The housing 50 includes a locking device 52, e.g., a wing nut. The housing 50 includes a housing part 50b (see Fig. 3 ), which is rotatable along its longitudinal axis. This means that the axis of rotation of the possible rotation of the housing part 50b is oriented perpendicular to the main surface of the support element 25. In Figure 1 The axis of rotation of the housing part 50b is indicated by a dashed-dotted line 52a. The first ball joint 30 is rotatable within the housing 50 by three rotational degrees of freedom, insofar as the housing 50 allows (see also Figure 3and the description there). Both the position of the first ball joint 30 and the orientation of the housing part 50b can be fixed or secured by means of the locking device 50.

[0047] The telescopic rod 26 has a variable length. This variable length is provided by extension elements 27. The telescopic rod 26 has a single translational degree of freedom corresponding to its longitudinal axis. The overall length of the telescopic rod 26 is variable along its longitudinal axis by means of the extension elements 27. The telescopic rod 26 includes a locking mechanism to secure (fix) the overall length. The telescopic rod 26 also includes a first section 26a at the end facing the first ball joint 30 and a second section 26b at the opposite end. The first section 26a has a kink or curve enclosing an angle β. The enclosed angle β is preferably more than 70 degrees and less than 170 degrees, more preferably more than 110 degrees and less than 150 degrees. More preferably, the enclosed angle β is substantially (135 ± 10) degrees.The second section 26b has a bend or curve that encloses an angle γ. The enclosed angle γ is preferably more than 10 degrees and less than 90 degrees, more preferably more than 30 degrees and less than 60 degrees. Further preferably, the enclosed angle γ is substantially (45 ± 10) degrees. Sections 26a and 26b and their bends are each optional. The telescopic rod 26 can also be designed without sections 26a and 26b.

[0048] The telescopic rod 26 further comprises a retaining 31 at the end opposite the support element 25. A second ball joint 32 is at least partially enclosed by the retaining 31. A clamping element 34, which holds the terminal device 36, is mounted on the second ball joint 32. The orientation and / or position of the clamping element 34 is variable relative to the telescopic rod 26 by means of the second ball joint 32. Furthermore, the orientation and position of the clamping element 34 relative to the support element 25 and / or thoracic section 22, and thus to the person 12, are variable relative to the first ball joint 30, the telescopic rod 26, and the second ball joint 32. The position of the second ball joint 32 can be locked or fixed by means of the retaining 31. The retaining 31 may, for example, provide a pinch protection device for this purpose.

[0049] The clamping element 34 is designed to clamp the terminal device 36 securely, so that the terminal device 36 cannot be removed from the clamping element 34 without considerable force. The clamping can be achieved by a spring mechanism and / or retaining lugs 38, 39 projecting from the terminal device 36 (see Figure 3). Fig. 2 ) so that a positive locking connection is provided by the clamping part 34 and the terminal 36.

[0050] The first ball joint 30, the telescopic rod 26, and the second ball joint 32 enable the clamping element 34 to be positioned and / or oriented such that the terminal device 36 can be positioned and oriented according to the field of vision of the person 12. Thus, the holding device 10 ensures that the person 12 can interact advantageously with the terminal device 36, for example, by perceiving information displayed on the screen or by taking a digital photograph that includes at least a part of a self-portrait.

[0051] The first ball joint 30, the telescopic rod 26, and the second ball joint 32 thus form an intermediate piece that enables the connection of the clamping part 34 to the support element 25. The intermediate piece can be folded towards and away from the body. The intermediate piece can also be rotated 360 degrees, with the axis of rotation being oriented essentially perpendicular to the support element.

[0052] Figure 2 Figure 1 shows a simplified schematic representation of the holding device 10 according to one embodiment in a front view.

[0053] This view illustrates the construction of the first component 20. The thoracic section 22 has two essentially parallel segments extending from the support element 25. The distance between the segments then widens and remains essentially constant until the two segments are joined or connected by the neck section 24 in the area of ​​the posterior shoulder section 23 in the neck region of the person 12 (shown by the dashed line). However, it is also conceivable that the first component 20 may deviate from the design shown here in terms of its basic shape in order to adapt even more closely to the body shape of the person 12. In this respect, the first component 20 may have additional bends, or the distances between the segments may vary.

[0054] This view also shows that the clamping element 34 has retaining lugs 38, 39 that project beyond the terminal device 36. The retaining lugs 38, 39 can be connected by a spring mechanism, so that the terminal device is clamped by the retaining lugs 38, 39. The terminal device 36 can only be removed from the clamping element 34 if the retaining lugs 38, 39 are separated by force. Alternatively, the clamping element 34 can receive the terminal device 36 in another suitable manner. For example, the clamping element 34 can provide a suction cup connection with the terminal device 36.

[0055] Figure 3Figure 1 shows a simplified schematic perspective view of the first ball joint 30 in the housing 50. The support element 25 has its main surface 25b oriented away from the person 12. The housing 50 is arranged on the main surface 25b. The housing 50 comprises a first housing part 50a and a second housing part 50b. The housing 50 at least partially encompasses (encloses) the first ball joint 30. The first housing part 50a is fixed to the main surface 25 in a rotationally and positionally fixed manner. The second housing part 50b is rotatable relative to the first housing part 50a. The axis of rotation is indicated by the dashed-dotted line 52a. The second housing part 50b includes a slot-shaped cutout 51, the upper end of which is indicated by a dashed line. The width of the cutout 51 corresponds to the diameter of the first section 26a of the telescopic rod 26.The first ball joint 30 can be oriented such that the first section 26a is aligned with the cutout 51. The first ball joint 30 and the second housing part 50b can be locked or fixed by means of the locking device 52, in this case a wing nut. On the one hand, the cutout 51 increases the number of different orientations achievable by the first ball joint 30 or the first section 26a of the telescopic rod. On the other hand, the cutout 51 provides additional stability to the first section 26a when the locking device 52 is engaged.

[0056] The interaction of the first ball joint 30, the second ball joint 32, the telescopic rod 26, and the rotatable housing part 50b defines a spatial volume accessible to the terminal device 36 within which the terminal device 36 can be positioned and oriented essentially freely. This spatial volume corresponds essentially to part of a spherical shell, the thickness of which is determined by the available effective length of the telescopic rod.
