HOLDER FOR A MOBILE DEVICE

Description

[0001] The present invention relates to a holder for a mobile device.

[0002] Device holders are widely known and are generally used to attach and securely hold mobile devices such as mobile phones, tablets, portable computers, GPS (Global Positioning System) receivers and PDAs (Personal Digital Accessories).

[0003] Due to the wide variety of device dimensions and button positions, mounting mechanisms must be adjustable and offer a high degree of flexibility if they are to accommodate a wide range of devices. For example, US 7,418,097 describes a clamp for electronic devices that includes two spring-loaded edge clamps (or arms) and a spring-loaded release element. The distance between the clamps is variable, and the mobile device is clamped by inserting the device between the clamps. Moving the clamps together compresses their spring tension. Pressing the release mechanism releases the clamps, which separate due to their spring tension to free the mobile device. Holders with two clamps are known, for example, from US 2012 / 018595 A1 and US 2005 / 072691 A1.

[0004] However, accommodating a large number of devices has led to complicated mounting systems, as shown in US 7 418 097, which are expensive to manufacture and prone to defects due to the large number of components.

[0005] One objective of the present invention is to offer an improved holder for mobile devices that has a simple design and is therefore robust, easy to use, uncomplicated and easy to manufacture.

[0006] According to claim 1, a holder for a mobile device is provided in accordance with the invention.

[0007] Further preferred embodiments can be found in the dependent claims.

[0008] By providing an area with non-linear resistance to the separation of the first edge clamp and the second edge clamp, a lower rate of increase in separation resistance is achieved at larger separation distances compared to the use of a linear element, such as a helical spring.

[0019] Particularly suitable elastomers are advantageously polybutadiene, synthetic rubber, silicone rubber or natural rubber, as well as other vulcanizable thermoplastics.

[0020] Embodiments of a holder include a first edge ejector configured and arranged to move the first edge clamp away from the second edge clamp in order to release the proximal edge of the mobile device when the first predetermined ejection force is applied against the first edge ejector.

[0021] Embodiments of a holder further comprise a first ejection projection which is mechanically connected to the first edge ejector and is designed and arranged to rotate the first edge clamp about the first axis when the first predetermined ejection force is exerted against the first edge ejector, whereby the first ejection projection exerts a second predetermined ejection force against the movable device along a third axis, the third axis intersecting the first and second axes.

[0022] Embodiments of a holder further include a second edge ejector which is mechanically connected to the second edge clamp and is designed and arranged to rotate the second edge clamp about the first axis and / or to move the second edge clamp away from the first edge clamp in order to release the proximal edge of the mobile device when a third predetermined ejection force is applied against the second edge ejector.

Detailed description

[0038] Fig. 1 shows a holder 100 for a mobile device 200. More precisely, shows Fig. 1A A top view of the holder 100 seen from the side on which the mobile device 200 is inserted and / or removed. Fig. 1B shows a cross-section through the edge clamp along the in Fig. 1A line BC-BC shown. Fig. 1Calso shows a cross-section through the edge clamp along the BC-BC line, but one of the edge clamps is shown during the ejection of the device.

[0039] The holder 100 comprises a first edge clamp 110 extending along a first axis 170, and a second edge clamp 115 also extending along a first axis 170.

[0040] The outline of the mobile device 200 is indicated by dashed lines.

[0041] Optionally, the first edge clamp 110 and the second edge clamp 115 can be designed and arranged such that substantially parallel edges of a mobile device 200 are rigidly clamped by being substantially parallel to each other. In embodiments in which the first edge clamp 110 and the second edge clamp 115 extend over a substantial portion of the edges of the mobile device 200, the uniformity of the clamping can be improved by ensuring that the first edge clamp 110 and the second edge clamp 115 are substantially parallel to match the degree of parallelism of the edges of a typical mobile device 200.

[0042] The first edge clamp 110 and the second edge clamp 115 are designed and arranged to interact along a second axis 175 to rigidly clamp opposite edges of the mobile device 200. Typically, a force of up to 15 Newtons (N) can be applied. The applied force may be related to the degree of movement expected during use. For example, lower forces may be used for clamping in a table mount compared to a mount to be attached to a bicycle.

[0043] The second axis 175 intersects the first axis 170. The angle between the first axis 170 and the second axis 175 can be predetermined depending on the expected external shape of the mobile devices 200 to be held. Currently, most mobile devices are essentially rectangular, so it may be advantageous if the first axis 170 and the second axis 175 intersect essentially perpendicularly.

[0044] In the context of this description, the term "predetermined" refers to one or more of the following possibilities for determining values: which were determined during the design of the relevant parts using simulation data and / or measurements; which were determined during use by measurements and / or empirically ("trial and error") (it is therefore predetermined for later use); which are determined during use, allowing for dynamic determination and optional dynamic adjustment of the relevant parameter or training.

[0045] The holder 100 further comprises one or more strain resistances 120, which are designed and arranged to form a region with nonlinear resistance to the separation of the first edge clamp 110 and the second edge clamp 115 along the second axis 175. If the holder 100 is designed for use with substantially planar mobile devices (200), it may be advantageous to provide the strain resistance in a plane encompassing the first axis 170 and the second axis 175.

[0046] At least one strain resistance 120 is required, which has a basic body composed of serpentine or zigzag-shaped elements. Compared to helical springs, serpentine or zigzag-shaped (and hereafter referred to simply as serpentine) strain resistances 120 can be designed to exhibit a suitable strain resistance characteristic by selecting and varying parameters such as the meander shape, meander dimensions, the physical properties of the materials used, the cross-sectional shape and dimensions of the meanders, and the use of one or more joints. In some designs, additional connections between meanders can be used to further modify the strain resistance characteristic. For example, it may resemble a web more than a meander.

[0047] A serpentine or zigzag strain resistance 120 allows a high degree of customization of the strain resistance characteristic.

[0048] For example, at separation distances that are only slightly larger than the expected device size, an initial resistance is present. Once this initial resistance is overcome, a relatively lower resistance can be provided outside this initial range of separation distances. This can make it easier for the user to remove the device.

[0049] For example, a holder 100 that has an essentially constant separation resistance over a wide range of separation distances can thereby hold a variety of different sizes of mobile devices 200 more easily.

[0050] For example, a holder 100 that exhibits a lower rate of increase in separation resistance at larger separation distances compared to using a linear element, such as a helical spring, can therefore more easily hold a wide variety of mobile devices 200 in size. This is a common problem with known holders: when they are intended to hold very large (very wide) mobile devices 200, the force exerted by a linear spring would be too great for practical application.

[0051] Furthermore, the strain resistance characteristic can be further influenced by adding suitably designed elements, such as spring elements, spring wires, metal reinforcements, magnet pairs that are either attractive or repulsive, elastic elements, additional elastic or elastomeric elements.

[0052] Furthermore, the strain resistance characteristic can be further influenced by one or more strain resistances 120 with one or more joints (not in Fig. 1 (as shown), wherein the one or more joints can be arranged along the extension resistance 120 itself or between the extension resistance 120 and the first edge clamp 110 and / or second edge clamp 115. Any suitable joint configuration can be used as such a joint, e.g., one having one or more recesses, one or more notches, one or more grooves, one or more projections, one or more ridges, one or more webs, one or more ribs, or any combination thereof.

[0053] Additionally or alternatively, one or more reductions in the material's cross-sectional area (constrictions) can be used as hinges. These one or more reductions in cross-sectional area can, for example, be essentially constant along their length, taper, be adjacent and opposite each other, form a barrel-shaped profile, an hourglass-shaped profile, an essentially spherical profile, an essentially hemispherical profile, a cylindrical profile, or any combination thereof.

[0054] One or more joints can be designed and arranged to allow additional rotation if required. Additionally or alternatively, they can provide a target pull volume, similar to a rotary joint. Such joints can be used to further adjust the degree of tensile resistance 120 at different distances between the first edge clamp 110 and the second edge clamp 115.

[0055] The one or more strain reliefs 120 are designed and arranged such that they offer a relatively high resistance to the separation of the terminals 110, 115 in the area of ​​the separation distances for which the holder 100 is provided. This can reduce the risk of the mobile device 200 falling out during use.

[0056] Tables of device dimensions are widely available, e.g., accessed online on August 6, 2020, at www.dimensions.com / subcategories / digitaltypes. Typically, mobile phones vary in width from 55 mm to 80 mm. Typically, tablets vary in width from 70 mm to 225 mm.

[0057] It can therefore be advantageous to provide a variety of holders 100, each optimized to offer a relatively higher tensile strength for a range of mobile device widths. For example, small corresponds to a range of 50 mm to 60 mm, medium to a range of 60 mm to 70 mm, and large to a range of 70 mm to 80 mm for mobile phones. Similarly, differently optimized holders 100 can be provided to accommodate tablets 200 of various sizes.

[0058] Additionally or alternatively, the holder 100 can be designed and arranged so that the user can select or modify the range of usable widths. For example, by designing the strain resistances 120 to be user-replaceable.

[0059] Additionally or alternatively, the separation distance between the first edge clamp 110 and the second edge clamp 115 can be adjusted, for example with the help of a thread adjuster.

[0060] Additionally or alternatively, the holder 100 can be designed and arranged to allow a wide range of usable widths above a minimum. For example, a minimum distance between the edge clamps 110, 115 of approximately 35 mm to 40 mm would allow for the holding of simple mobile phones, and a minimum distance of approximately 52 mm would allow for more complex phones, such as smartphones. At this distance, the strain resistance 120 would preferably be designed and arranged to achieve its minimum strain value.

[0061] Serpentine strain gauges 120 have the additional advantage of being relatively flat, allowing for the production of more compact device carriers 100. They can also be conveniently manufactured using techniques such as extrusion, casting, bonding, or 3D printing.

[0062] Fig. 1B shows a cross-section through the edge clamp along the in Fig. 1A The line BC-BC is shown. The outline of the cross-section of the mobile device 200 is shown by dashed lines. Fig. 1B shows the situation after the mobile device 200 has been inserted, and the strain resistance 120 resists the edge clamp 110, 115, which separate along the second axis 175.

[0063] The edge clamps 110, 115 are designed and arranged to clamp the edges of the mobile device 200 by forming two opposing wall surfaces 110, 115 facing each other and extending along a third axis 177. These wall surfaces 110, 115 face the edges of the device 200 when in use. The extension along the third axis 177 can be determined based on the range of thicknesses of the mobile device to be accommodated. Typically, mobile phones can vary in depth (thickness) from 6.5 mm to 10 mm. Typically, tablets can vary in depth (thickness) from 5.5 mm to 15 mm. The third axis 177 intersects the first axis 170 and the second axis 175.

[0064] It can therefore be advantageous to provide several holders 100, each preferably cascaded, preferably in the vertical height, optimized for clamping a range of depths (thicknesses) of mobile devices. For example, small corresponds to a range of 6 mm to 9 mm, medium to a range of 8 mm to 12 mm, and large to a range of 11 mm to 16 mm.

[0065] Additionally or alternatively, the holder 100 can be designed and arranged so that the user can select or modify the range of usable depths. For example, by designing the edge clamps 110, 115 to be user-replaceable. Additionally or alternatively, the extension of the edge clamps 110, 115 along the third axis 177 can be adjusted, for example, by using a setscrew thread.

[0066] Additionally or alternatively, the holder 100 can be designed and arranged to allow a wide range of usable depths up to a maximum. For example, the wall surfaces of the edge clamps 110, 115 can extend approximately 10.6 mm along the third axis 177.

[0067] Optionally, the wall surfaces of the edge clamps 110, 115 can have a profile to improve the gripping of the opposite edges of the mobile device 200.

[0068] Currently, most mobile devices are essentially rectangular in cross-section, so it may be advantageous if the second axis 175 and the third axis 177 intersect essentially perpendicularly.

[0069] The wall surfaces of the edge clamps 110, 115 can therefore be essentially perpendicular to the second axis 175. Optionally, one or more wall surfaces can have a C-shaped or L-shaped cross-section to reduce the risk of the mobile device 200 being ejected during normal use.

[0070] The term "ejection" is used in this description to refer to the removal of the mobile device from the holder 100. This may include steps that occur due to the design and arrangement of the holder 100. For example, if the edge clamp 110 is C-shaped, then a corresponding rotation of the edge clamp 110 will also cause the edge of the mobile device 200 to be "lifted" (moved away from the holder 100). "Ejection" may also include manual and / or manually assisted steps. For example, in some configurations, the edge clamp 110 may detach from the edge of the mobile device 200, allowing the user to manually lift the edge of the mobile device 200 out.

[0071] Optionally, one or both wall surfaces of the edge clamps 110, 115 can be slightly inclined towards each other, so that the separation distance on the side of the mobile device 200 facing away from the holder 100 is somewhat smaller (the top side as in Fig. 1B and Fig. 1C (as shown). In other words, one or both wall surfaces of the two edge clamps 110, 115 can, viewed in cross-section, form an angle less than 90 degrees (less than perpendicular), preferably about 75 degrees, with the second axis 175.

[0072] The holder 100 further comprises a first edge ejector 130, which is mechanically connected to the first edge clamp 110 and is designed and arranged to rotate the first edge clamp 110 about the first axis 170. The edge ejector 130 can be located at any position on the first edge clamp 110 that is easily accessible to the user when attempting to eject the mobile device 200. For example, it can be, as in Fig. 1A shown to be a tab that is rigidly attached to the first edge clamp 110 on the side facing the user and away from the holder 100 (the top side, as shown in Fig. 1B and Fig. 1C(shown). It can be attached at any suitable position along the first axis 170 and is preferably attached at a central position of the first edge clamp 110 to allow rotation over a large section of the first edge clamp 110. More than one edge ejector 130 can be attached at different locations along the edge clamp 110.

[0073] Fig. 1C shows a cross-section through the edge clamps 110, 115 along the line BC-BC (shown in Fig. 1A ), at the moment when a proximal edge of the mobile device 200 is released from the first edge clamp 110.

[0074] As in Fig. 1CAs shown, the first edge ejector 130 is designed and arranged such that it rotates the first edge clamp 110 about the first axis 170 when a first predetermined ejection force 300 is applied to the first edge ejector 130. Since this is used to eject the mobile device 200, the rotation of the edge clamp should be sufficient to release the proximal edge of the device 200.

[0075] In practice, it can happen that the user does not apply the force 300 at the optimal position on the first edge ejector 130 in the optimal direction to achieve optimal rotation. The design and arrangement are therefore such that a wide range of forces 300, applied at several different angles 300, is sufficient to eject the edge of the mobile device 200. Additionally, the effect of the shape of the wall surfaces of the edge clamp 110 and each angle should also be taken into account.

[0076] The holder 100 is similarly designed and arranged so that sufficient force can be applied to the first edge ejector 130.

[0077] The first edge ejector 130 is designed and arranged such that the proximal edge of the mobile device 200 is ejected when a person applies the first predetermined ejection force 300 as follows: preferably manually, with one or two hands; preferably with one hand; even more preferred is the use of only one or two fingers of one hand. A finger may be an index finger or a thumb; best with a finger and thumb of one hand or a combination thereof.

[0078] From an ergonomic point of view, the preferred range for the first predetermined ejection force 300 is between 6 and 10 Newtons (N).

[0079] It will be obvious to the expert that similar considerations apply when the mobile device 200 is inserted into the holder 100 to be rigidly clamped between the first edge clamp 110 and the second edge clamp 115. The main difference is that the user may be able to access more positions of the holder 100, as these are (at least initially) not blocked by the mobile device 200 itself.

[0080] It can be advantageous to use a similar procedure and the same edge ejector 130 when inserting the device 200 as when ejecting it. This makes the use of the holder 100 particularly intuitive.

[0081] It will also be obvious to the expert that only one of the edge clamps 110, 115 needs to be mechanically connected to an edge ejector (130).

[0082] For example, one of the edge clamps 110, 115 can be designed and arranged so that it does not allow any significant rotation and / or significant movement, in which case it would act as a mechanical stop for the mobile device 200, and the insertion / ejection would have to take place at the other edge clamp 110, 115.

[0083] It may also be advantageous to further design and arrange the first edge ejector 130 to move the first edge clamp 110 away from the second edge clamp 115 to release the proximal edge of the mobile device 200 when the first predetermined ejection force 300 is applied against the first edge ejector 130.

[0084] In addition to the rotation around the first axis 170, an additional movement can be provided to eject the proximal edge of the mobile device 200 more easily, reliably, quickly or with less force.

[0085] Additionally or alternatively, the holder 100 may include a second edge ejector 135 which is mechanically connected to the second edge clamp 115 and is designed and arranged to rotate the second edge clamp 115 about the first axis 170 and / or move the second edge clamp 115 away from the first edge clamp 110 to release the proximal edge of the mobile device 200 when a third predetermined ejection force (the second predetermined ejection force is described below) is applied against the second edge ejector 135.

[0086] Optionally, the holder 100 can be designed and arranged to provide two edge ejectors 130, 135. These can be designed and arranged to be used alternatively, with each being capable of ejecting the mobile device 200. Combined use is also permissible, for example, by designing and arranging the first predetermined ejection force 300 and the third predetermined ejection force to be substantially different, similar, or essentially the same.

[0087] The person skilled in the art will recognize that the explanations in this disclosure relating to the design and arrangement of the first predetermined ejection force 300 can be applied to the design and arrangement of the third predetermined ejection force.

[0088] It will also be obvious to the person skilled in the art that the design and arrangement of the two forces must be essentially the same, but that the construction, arrangement and design of the edge ejectors 130, 135 and the corresponding edge clamps 110, 115 need not be essentially the same.

[0089] It can be advantageous to design and arrange the construction, arrangement, and configuration of the edge ejectors 130, 135 and the corresponding edge clamps 110, 115 so that they are essentially identical. In this case, the holder can be used in both directions.

[0090] By appropriately designing two edge ejectors 130, 135 and the corresponding edge clamps 110, 115, it can be more convenient to design the holder 100 so that the first predetermined ejection force (300) and the third predetermined ejection force are suitable for manual application by two fingers on a person's hand.

[0091] The mobile device 200 can then be removed by essentially simultaneous pressure from two fingers, applying pressure on both sides.

[0092] One of the parameters that can influence the use and the formation and arrangement of one or more forces are the materials used and the components used for these materials.

[0093] For example, the first edge clamp 110, the second edge clamp 115, the one or more expansion resistances 120, the one or more joints 125 or any combination thereof can consist of one or more elastomers or a combination of elastomers, and these parts together can preferably be formed as monolithic.

[0094] It is particularly advantageous if one or more elastomers are polyurethane or rubber.

[0095] If one or more elastomers are included in the one or more strain resistances 120, their use is preferably limited to the relevant elastic deformation range. For all materials used in the strain resistances 120, a significant degree of plastic deformation should preferably be avoided.

[0096] The use of one or more elastomers in the edge clamp 110, 115, especially in the wall surfaces, is preferred, as this reduces the risk of damage to the mobile device 200 during rigid clamping.

[0097] Although not in Fig. 1As shown, the holder 100 can optionally include one or more fastening means designed and arranged so that the holder 100 can be rigidly attached to a support surface (not shown). Examples of support surfaces include a desk, a vehicle dashboard, a vehicle sun visor, a vehicle steering wheel, a photographic mount, a lighting device, or a piece of clothing.

[0098] Depending on the type of contact surface, the required fastening strength, and the desired appearance, the fastening element can consist of one or more fasteners, for example, a magnet, an electromagnet, a magnetic coil, a ferromagnetic metal, an adhesive, an adhesive pad, a hook fastener, a loop fastener, a threaded fastener, a threaded hole, a clamp, a spring clamp, a latch, a pin, a recess, a projection, a groove, a bracket, a clamping bracket, a screw bracket, a bayonet bracket, a friction bracket, a smooth surface, a suction cup, an adhesive pad, an elastic cord, or any combination thereof.

[0099] It can be advantageous to use a fastener that does not require an energy source to achieve a certain fastening strength.

[0100] For example, one or more permanent magnets, one or more bistable magnets that the user can move mechanically. This can prevent unwanted detachment during a power outage and / or during startup / shutdown.

[0101] If an energy source is integrated into the mounting surface, this can be advantageous for one or more electromagnets. For example, a bistable detent magnet designed and positioned to maintain a fixed position without the energy source. In this case, an energy source is required to reduce the degree of mounting force, which can also prevent unwanted detachment during a power outage and / or during start-up / shutdown.

[0102] Optionally, the holder can be adjusted to 100 in Fig. 1Additionally, they may have a projection to increase the surface area to which one or more fasteners can be mechanically attached. It may be advantageous to mechanically connect such a projection to the first edge clamp 110 and / or the second edge clamp 115. However, indirectly attaching one or more fasteners to the first edge clamp 110 and / or second edge clamp 115 may increase the force required (the initial ejection force 300) to eject the mobile device 200. In this case, it is preferable to use less rigid materials and / or to provide an additional projection that incorporates one or more fasteners not connected to the first edge clamp 110 and / or the second edge clamp 115.

[0103] Fig. 2A , 2B and 2CFigure 1 shows a top view of a second embodiment of the holder for mobile devices 101 and two cross-sections through the edge clamps 110, 115.

[0104] Holder 101 in Fig. 2 is identical to the first embodiment (holder 100) described above with regard to, except for one exception. Fig. 1The second edge ejector 135 is similarly mechanically connected to the second edge clamp 115, but instead of being located only at one point as a tab, it extends substantially over the entire extension of the second edge clamp 135 along the first axis 170. This is advantageous for the user because the third predetermined ejection force can be applied at any position. The first edge ejector 130 is similarly mechanically connected to the first edge clamp 110, but instead of being located only at one point as a tab, it extends substantially over the entire extension of the first edge clamp 130 along the first axis 170. This is advantageous for the user because the first predetermined ejection force 300 can be applied at any position. See below, however, for the additional training requirements due to an additional ejection projection 140.

[0105] The holder 101 includes a second strain resistance 120, which also includes one or more serpentine or zigzag shaped elements designed and arranged to provide an area of ​​nonlinear resistance to the separation of the first edge clamp 110 and the second edge clamp 115.

[0106] For the holder 101, the first and second strain resistances 120 are designed and arranged to resist separation of the first edge clamp 110 and the second edge clamp 115 along the second axis 175, similar to the functionality described above for the single strain resistance 120 contained in the holder 100. This can be advantageous because higher degrees of strain resistance force and / or smaller strain resistances 120 can be provided to offer a similar degree of strain resistance.

[0107] The use of two 120 strain resistances results in a more symmetrical appearance, resembling a violin-like or cotiate-like shape.

[0108] The holder 101 also includes a first ejection projection 140. This functions similarly to the C-shaped edge clamping surface described above. The first ejection projection is described in more detail below.

[0109] Fig. 2A shows a top view of the holder 101 seen from the side, on which the mobile device 200 is inserted and / or removed.

[0110] Fig. 2B shows a cross-section through the edge clamp along the in Fig. 2A The line BC-BC shown. The outline of the cross-section of the mobile device 200 is shown by the dashed lines. Fig. 2BThe situation after the mobile device 200 is inserted is shown, and the strain resistances 120 resist the edge clamp 110, 115, which separate along the second axis 175.

[0111] The first ejection projection 140 is mechanically connected to the first edge ejector 130 and is designed and arranged such that the edge clamp 110 rotates about the first axis 170 when the first predetermined ejection force 300 is applied against the first edge ejector 130.

[0112] Fig. 2C shows a cross-section through the edge clamp 110, 115 along the line BC-BC (shown in Fig. 2A ), at the moment when a proximal edge of the mobile device 200 is released from the first edge clamp 110. As in Fig. 2CAs shown, the first ejection projection 140 is further developed and arranged to exert a second predetermined ejection force 400 against the mobile device 200 along a third axis 177. This can be particularly advantageous because the degree of manual lifting that may be required to remove the mobile device 200 from the holder 101 is greatly reduced and, in some embodiments, is no longer necessary. The first predetermined ejection force 300 can therefore be reduced.

[0113] The third axis 177 intersects the first axis 170 and the second axis 175. Optionally, the second axis 175 and the third axis 177 can intersect essentially perpendicularly.

[0114] Although in Fig. 2Not shown, the holder 101 may optionally include one or more fastening means designed and arranged such that the holder 101 can be rigidly attached to a support surface (not shown). The considerations are similar to those given above for the holder 100 of Fig. 1 were described.

[0115] Holder 101 of Fig. 2 However, it still includes the first ejection projection 140. Its relatively large surface area makes it a practical component to which one or more fasteners can be mechanically attached. However, attaching one or more fasteners to the first ejection projection 140 can significantly increase the force required, namely the initial ejection force 300, to eject the mobile device 200.

[0116] If, for example, the first edge clamp 110, the first edge ejector 130, and the first ejection projection 140 are made of rigid materials and rigidly connected to one another, then any fastener contained in the first ejection projection 140 will offer high resistance to the rotation of the edge clamp 110 about the first axis 170. As a test, a permanent magnet with a diameter of approximately 19 mm was inserted into the first ejection projection 140, and the contact surface was made of a ferromagnetic metal, which provides a high degree of fixation. In the absence of fasteners, the first ejection force 300 was typically in the range of 6 to 10 Newtons. After including the permanent magnet, the first ejection force 300 was 12 to 15 Newtons.

[0117] If increasing the first ejection force 300 is not acceptable in certain embodiments, it is preferable to use less stiff materials and / or to provide a further projection with one or more fasteners that is not connected to the first edge clamp 110 or second edge clamp 115.

[0118] Fig. 3A and 3B Figure 1 shows a top view of a third embodiment of the holder for mobile devices 102 and a cross-section through the edge clamp.

[0119] Holder 102 of Fig. 3 is identical to the second embodiment (holder 101) with one exception, which is described above in relation to Fig. 2 The holder 102 also includes a second ejection projection 145. This functions similarly to the first ejection projection 140 and is described in more detail below.

[0120] Fig. 3Ashows a top view of the holder 102 seen from the side, on which the mobile device 200 is inserted and / or removed.

[0121] Fig. 3B shows a cross-section through the edge clamp along the in Fig. 3A The outline of the cross-section of the mobile device 200 is shown by dashed lines. Fig. 3B The situation after the mobile device 200 has been inserted is shown, and the strain resistances 120 resist the edge clamps 110, 115, which separate along the second axis 175.

[0122] Similar to holder 101 from Fig. 2 The first ejection projection 140 is mechanically connected to the first edge ejector 130 and is designed and arranged such that it rotates the first edge clamp 110 about the first axis 170 when the first predetermined ejection force 300 is applied against the first edge ejector 130.

[0123] Holder 102 of Fig. 3However, it still includes the second ejection projection 145, which is mechanically connected to the second edge ejector 135 and is designed and arranged such that it rotates the second edge clamp 115 about the first axis 170 when the third predetermined ejection force (not shown, but analogous to the first ejection force 300) is applied against the second edge ejector 135.

[0124] The moment when the proximal edges of the mobile device 200 are released from the first edge clamp 110 and the second edge clamp 115 is not shown. It should be noted that... Fig. 2C referred to, which shows a one-sided ejection. The holder 102, as in Fig. 3 As shown, it is designed in an analogous manner for ejection from both sides.

[0125] Similar to holder 101 from Fig. 2The first ejection projection 140 is further designed and arranged in such a way that it exerts a second predetermined ejection force 400 against the mobile device 200 along a third axis 177.

[0126] Holder 102 of Fig. 3 However, it still includes the second ejection projection 145, which is designed and arranged to exert a fourth predetermined ejection force against the mobile device 200 along a third axis 177.

[0127] This can be particularly advantageous because the degree of manual lifting that may be required to remove the mobile device 200 from the mount 102 is greatly reduced and, in some training scenarios, no longer necessary. The first predetermined ejection force 300 and the third predetermined ejection force can both be reduced.

[0128] Similar problems to those mentioned above can occur if one or more fasteners are included in the first ejection projection 140 and / or the second ejection projection 145. It can be advantageous to incorporate strong fixings in only one ejection projection 140, 145. This allows for both improved ejection (limited to only one side) and strong fixation.

[0129] Figs. 4A and 4B Figure 1 shows a scale top view of a fourth embodiment of the holder for mobile devices 103 and a scale cross-section through the edge clamp.

[0130] The scale drawings should not be interpreted as limiting the invention to specific dimensions and ratios. They merely serve to provide the person skilled in the art with a starting point for further evaluation and routine testing. By following routine steps guided by the general guidance in the remainder of this disclosure, the person skilled in the art will be able to provide a wide variety of holders suitable for holding a multitude of devices.

[0131] Holder 103 of Fig. 4 is identical to the third embodiment (holder 102) with one exception, which is described above in relation to Fig. 3as described. The views are less schematic and not to scale. The wall surfaces of the edge clamps 130, 135 facing the edges of the device 200 are curved, thus concentrating the clamping force at two positions near opposite ends of the edge clamps 130, 135. This curvature provides a convenient recess to reduce the likelihood of a button being pressed. Such buttons are commonly found on the edges of edge clamps 200. The gripping sections of the first edge ejector 130 and the second edge ejector 135 of the edge clamps 110, 115 have ribs to improve gripping. These are shown in cross-section in Fig. 4B to see

[0132] Similar to holder 102 from Fig. 3The holder 103 comprises two expansion resistors 120. However, within the holder 103, each expansion resistor 120 comprises two joints 125, one at each connection point between the expansion resistor 120 and the rest of the holder 103. In other words, the holder 103 has four joints 125. As can be seen from the magnification, each joint 125 has one or more cross-sectional reductions. More precisely, each joint 125 comprises one or more tapers. Even more specifically, each joint 125 comprises two adjacent cones that form an hourglass-shaped longitudinal profile. This can be advantageous because it provides a pivot point at the smallest cross-section, which is used when the edge clamps 110, 115 move apart (a larger separation distance) and / or when they move together (a smaller separation distance).

[0133] The holder 103 is essentially monolithic, as it is formed from a polybutadiene, a silicone rubber, a synthetic rubber, natural rubber and / or a material with properties like natural rubber.

[0134] The ejection projections 140, 145 are not used as such. Each additional projection incorporates a permanent magnet as a fastening means for the holder 103 on a support surface. Due to the elasticity of the polyurethane, the mobile device is ejected solely by applying the first ejection force to the first edge ejector 130 of the first edge clamp 110 and / or by applying the third ejection force to the second edge ejector 135 of the second edge clamp 115.

[0135] Fig. 4A shows a scale top view of the holder 103 seen from the side, on which the mobile device 200 is inserted and / or removed.

[0136] In this example, the maximum vertical extension 170a along the first axis 170 (or the height when viewed from the side on which the device 200 is inserted and / or removed) is approximately 60 mm.

[0137] Fig. 4B shows a scale cross-section through the edge clamp along the in Fig. 4A line BB shown. Fig. 4B This shows the situation in which no mobile device was used.

[0138] In this example, the maximum vertical elongation 175a along the second axis 175 (or the width when viewed from the side on which the device 200 is inserted and / or removed) is approximately 75 mm.

[0139] In this example, the average vertical separation distance can be 175b along the second axis and 175b at the top, as shown in Fig. 4BThe distance shown is considered the minimum separation distance. Here it is approximately 52 mm, so holder 103 would be recommended for devices 200 with an extension of 52 mm and higher.

[0140] The moment when the proximal edges of the mobile device 200 are released from the first edge clamp 110 and the second edge clamp 115 is not shown. It is assumed that Fig. 1C referred to, which shows a one-sided ejection. The holder 103, as in Fig. 4 The embodiment shown is designed analogously for ejection on both sides. As described above, in this embodiment the ejection projections 140, 145 are not used as such.

[0141] In this example, the two wall surfaces of the edge clamps 110, 115 are slightly inclined towards each other, so that the separation distance 175b is somewhat smaller on the side of the mobile device 200 facing away from the holder 100 (the top side as in Fig. 4B(shown). Here, the upper separation distance 175b is approximately 52 mm, the lower separation distance approximately 55 mm.

[0142] In other words, the two wall surfaces of the edge clamps 110, 115 form a cross-section of Fig. 4B As seen with the second axis 175, each angle is less than 90 degrees (less than perpendicular), preferably approximately 75 degrees. Here, the angle on each side is approximately 78 degrees.

[0143] The maximum vertical strain 177a is shown along the third axis 177 of a strain resistance 120 (thickness). Here it is approximately 3.4 mm and the cross-section of the strain resistance 120 is approximately circular. The outer diameter of the cross-section is therefore approximately 3.4 mm.

[0144] The mean vertical extension 177b is shown along the third axis 177 of a midplane of the edge clamp 110, 115. Here it is approximately 8.5 mm. This is also approximately the greatest distance along the third axis 177 by which the second edge ejector 135 can be moved for inserting and / or removing the mobile device 200.

[0145] The average perpendicular elongation 177c is shown along the third axis 177 of an upper plane (as depicted) of the edge clamps 110, 115. Here it is approximately 14 mm. This is also approximately the maximum perpendicular elongation along the third axis 177 of the holder (or the maximum thickness).

[0146] The average expansion of the wall surfaces 110, 115 facing the edges of the mobile device 200 (when in use) is approximately 13 mm in the illustrated case.

[0147] Fig. 4Cis a scale drawing of one of the two serpentine strain resistances 120, as shown in Fig. 4A (Top view) and 4B (cross section) are shown.

[0148] The maximum vertical strain 170b is shown along the first axis 170 of one of the strain resistances 120 (thickness). Here it is approximately 3.4 mm and the cross-section of the strain resistance 120 is approximately circular. The outer diameter of the cross-section is therefore approximately 3.4 mm.

[0149] The maximum perpendicular elongation 175c is shown along the second axis 175 of the serpentine elongation resistance 120 between the connection points with the remainder of the holder 103 (or width). In this case, the connection points consist of joints 125 on each side, so it is approximately the elongation between the joints 125. In this case, it is approximately 50.5 mm.

[0150] The maximum vertical strain 170c is shown along the first axis 170 of the serpentine strain resistance 120 (or height). In this case, it is approximately 19 mm.

[0151] The maximum vertical strain 175d is shown along the second axis 175 of the main meander of the serpentine strain resistance 120 (or width). In this case, it is approximately 36 mm.

[0152] The minimum vertical separation distance 175e is shown along the second axis 175 between the branches of the meander of the snake resistance 120. In this case, it is approximately 3 mm.

[0153] Fig. 5 Figure 500 shows an example of a strain force characteristic curve that includes a region of non-linear resistance due to the use of a serpentine strain resistance curve. It is represented as curve 500 using a solid line.

[0154] The force exerted by a strain resistance in Newtons is plotted along the vertical (or y-) axis from 0.0 N to 25.0 N. The strain of the strain resistance in mm is plotted along the horizontal (or x-) axis from 0.0 mm to 40.0 mm.

[0155] The tensile strength characteristic curve 500 passes through the following points: Elongation [mm] (x) Force [N] (y) 0.0 0.0 5.0 5.0 10.0 8.5 15.0 10.5 20.0 13.0 25.0 16.0 30.0 18.5

[0156] Fig. 5 Figure 510 further shows a linear extension force characteristic curve, represented as a dashed line. It passes through the (x,y) points (0,0); (5,5); (10,10); (15,15); (20,20) and (25,25). This represents a typical extension-resistance characteristic curve of a linear spring, such as a helical spring.

[0157] The nonlinear strain characteristic 500 follows the linear strain force curve 510 from the (x,y) point (0,0) to approximately (6 mm, 6 N). From this point onward, the nonlinear characteristic 500 exhibits a lower increase in strain force (or separation resistance) than the linear characteristic 510 for larger separation distances (here, for separations over approximately 10 mm). In this case, this means that the holder according to the invention facilitates easier insertion, removal, and holding of a wide size range of the mobile device 200, as the force required by the user to separate the edge clamp 110, 115 is reduced. For example, if a nonlinear resistance 500 is used at a distance of approximately 25 mm, a force of 16 N (Newtons) must be resisted instead of 25 N (Newtons). List of reference symbols
