Description

Field of the invention

[0001] The invention relates to a portable device and a method for scanning documents and arrangements of, in particular, three-dimensional imaging objects with the possibility of their simultaneous adaptation. Background and general description of the invention

[0002] The digitalization of teaching requires practical solutions. Teachers want to develop lessons together with their class and be able to directly incorporate their students' contributions into the lesson plan.

[0003] In previous generations, teaching material from print media or a script was handwritten or sketched onto the blackboard before the start of the lesson, or copied onto overhead transparencies and then shared with the class by projecting them onto the wall.

[0004] The poor legibility of colored chalk on a dark blackboard and the health risks posed by chalk dust in classrooms have led many schools to introduce whiteboards, which can also be used as screens for presenting slides on an overhead projector. However, the surfaces of whiteboards and the aforementioned slides require special fiber-tip pens, which are usually only available in a limited range of colors and, in our experience, only produce satisfactory writing when new. Furthermore, these often contain toxic substances.

[0005] Another method involved duplicating a paper template using a matrix printer or copier and distributing the copies throughout the class. This solution has the disadvantage of high ink and paper consumption. Furthermore, the sheets cannot be easily bound into a school notebook and are easily confused or lost.

[0006] Furthermore, it is a well-known practice to create digital teaching materials that students can access individually or in groups via portable computers.

[0007] Additionally, web pages can be incorporated into the teaching materials, making lessons more realistic and engaging. A disadvantage of this solution is that students are responsible for accessing the right pages at the right time and navigating them independently. Students can become distracted and feel disconnected without the teacher even noticing.

[0008] Alternatively, the teacher can project the image of his computer screen onto the wall or a suitable surface on the wall.

[0009] Each of the above-mentioned methods of sharing lesson-specific material with the class requires a preparatory step in which an intermediate document (a blackboard image, one or more labeled slides, a computer file, a printed sheet of paper) must be created and, if necessary, reproduced.

[0010] This disadvantage is overcome by tripods with an integrated camera, where the camera is aimed at a document, an object or an arrangement of objects and the collected image information is passed on to an external computer, for example via an output socket.

[0011] Instead of prepared interim copies that the class must pass through like milestones, handwritten notes, newspaper articles, and book pages can be spontaneously and flexibly incorporated into the lesson plan. The teacher can discuss student work completed in class with the class during the same lesson.

[0012] Experiments and demonstrations, especially in the natural sciences, which used to be viewed by rows of pupils being led past the desk one after the other with brief explanations, can now be shown to the entire class at the same time thanks to their magnified projection on the wall and can be commented on in detail in the same amount of time.

[0013] For simplicity, we assume one teacher and one class. However, the device is also applicable to other situations.

[0014] One disadvantage of tripods with integrated cameras is their high initial cost. This is due not only to the camera's complex technology, but also to the sturdy construction of the tripod that supports it. Such tripods are usually made of metal and are preferably non-disassemblable. Firstly, detachable connections can weaken the tripod's stability. Secondly, if the camera cannot be detached from the tripod, the integrity of the delicate camera cannot be fully guaranteed when concentrating on setting up and dismantling the tripod. Such a device cannot be considered portable given the sensitivity of its technology and its weight, as well as the bulky dimensions of its tripod. On the other hand, such a high-quality device cannot be left unattended in the classroom after use. Its use in schools therefore requires a minimum of foresight and planning.In addition, there are potential difficulties connecting the camera to the commonly available hardware and software for projecting onto a wall or connecting to a large screen. Considering the high initial cost, the device should be operational for many years.

[0015] In response to these problems and the rapid proliferation of portable computers such as tablets and mobile phones, which come standard with their own cameras, manufacturers have developed tripods that, instead of a camera, simply provide a mounting element for installing a portable computer. This has reduced acquisition costs and shifted the responsibility for protecting the technology outside of immediate use and ensuring its compatibility to the user.

[0016] Such a stand features an articulated arm, the lower end of which is designed to be secured to or on a tabletop. A mounting element for installing a portable computer can be located at the upper end, which can extend above the tabletop. The articulated arm must be of high quality to ensure both stable support for the portable computer and flexibility in the orientation of its mounting element. It is therefore typically made of a heavy metal and may feature multiple joints. These features result in relatively high production costs.

[0017] A simple clamp, a screw clamp or a heavy stand is provided for securing the tripod rod to the table surface, the latter being intended to hold the tripod rod upright on a horizontal flat table top by means of gravitational force.

[0018] The simple clamp has the disadvantage that it can only provide a secure hold on tabletops of a suitable thickness. Attaching a screw clamp requires both hands to hold the tripod rod upright and simultaneously screw the clamp. This requires a monotonous movement, repeatedly interrupted by re-gripping, which also requires increasing strength. The screw clamp is therefore unsuitable for short-term use and frequent assembly and disassembly. Both clamping devices have the disadvantage that not all tables have a cantilevered plate on which such a clamp can be attached. Experience has shown that school desks are often not among the types of tables to which such an articulated arm can be suitably clamped.

[0019] A stand can only stand securely on largely horizontal surfaces, whereby the width and weight of the stand are crucial for stabilizing the tripod rod.

[0020] In practice, it turns out that not all angles of the fastening element on such an articulated arm and not all extension heights of its tripod rod can be used without the articulated arm tipping over. The mobility of the articulated arm is limited depending on the portable computer in a way that may not be obvious to the user and may be discovered through experimentation, which can lead to the device accidentally tipping over and, in particular, damage to the portable computer. These limitations make it difficult for the user to find a configuration among the numerous parameters for the angle and length settings of the articulated arm that can move the portable computer's camera into the desired position and hold it securely in that position.

[0021] After removing the portable computer from the mounting bracket, the tripod can be disassembled. To ensure that the collapsible design does not compromise stability, additional technical, craftsmanship, and material-related solutions are required, which may be reflected in the price of the product. While the tripod can be stored in a space-saving manner if necessary, its wide base and heavy overall weight make it impractical to transport.

[0022] In order to set up the articulated arm or adjust it to different heights, a known method is to design the stand rod as two interlocking metal tubes that can be clamped into a socket or released from it by rotating against each other. Locking the two tubes requires two hands and can accidentally come loose during use, particularly under the weight of the installed portable computer, posing a risk of pinched fingers. Due to material fatigue, the lock can weaken over time and give way more easily, so that the attachment increasingly loses stability and has to be tightened with tools. However, the use and keeping tools on hand reduces the comfort of use. The only known solution is a tool holder installed on the articulated arm, but assembly and disassembly require time and skill.

[0023] The wide stand has the further disadvantage that it appears in the field of view when mounted with the camera axis perpendicular to the table surface and parallel to the tripod rod.

[0024] A known solution to this problem involves extending the upper end of the articulated arm parallel to the table surface to separate the attached portable computer from the stand. This compromises the stability of the articulated arm and therefore may not be an optimal solution for portable computers of varying weights.

[0025] Another solution involves making the mounting element at the upper end of the articulated arm pivotable, so that tilting the camera moves the image field away from the axis of the tripod rod. However, this leads to perspective distortion in the image.

[0026] Furthermore, the pivoting ability of the articulated arm has the disadvantage that technical, craft and material-related solutions must be found for the fastening element at the upper end of the articulated arm in order to hold the portable computer in positions where it would fall due to gravity.

[0027] Articulated arms are known in which the fastening element can clamp the portable computer. For convenient use, it is essential that the clamping device is easy to close and release.

[0028] DE 20 2014 008 454 U1 discloses a device that is spanned by three pairs of struts arranged at right angles to each other, one of which is designed as a foldable stand rod, while the other two together form the setup device. All parts are permanently connected to one another, and assembly can be carried out in a few simple steps without additional tools. The use of light metal such as aluminum makes the device comparatively light and inexpensive to produce, but also susceptible to stress-related damage such as deformation and cracks. The user device must be positioned so that the center of gravity of the device is close to the middle between the support points of the setup device. The device is therefore neither robust nor flexible and therefore not suitable for practical use.

[0029] In order to ensure the stability of the portable computer's attachment using simple means, devices are known on two or more supports on which the portable computer can be placed.

[0030] A bridge made of acrylic glass is known, comprising a pair of parallel, opposing supports and a horizontal support surface connecting them in one piece for placing or standing a portable computer and for scanning a document slid underneath. The frame has no movable or detachable parts, so adjusting the height of the support surface or folding or disassembling the bridge for convenient transport or space-saving storage is not possible. Furthermore, external light sources can cause unwanted light reflections during use.

[0031] The object of the present invention can therefore be seen in providing the user with a device for securely fastening his portable computer so that his camera can scan a teaching material placed in front of or below the device, for example a written sheet of paper or an open textbook, and forward the image information for projection onto the wall, a whiteboard or a screen, without the user having to intervene in the recording process in order to support the device, hold the portable computer or position the object to be imaged in the focus of the camera lens.

[0032] In a partial aspect or a further development of the invention, the object can be seen to be to provide a device which allows convenient engagement under the fastening element during the reproduction of the teaching material, so that the user can, for example, move the material shown or edit it by hand, and which simultaneously depicts this change process in the projection.

[0033] In a partial aspect or a further development of the invention, it can be considered an object that the width and height of the device can be adapted to the individual needs of the user and the circumstances of the object to be imaged.

[0034] In a further aspect or development of the invention, the object can be seen as providing a device which can be repeatedly assembled and disassembled in a few simple steps and which can also be adapted to changing device formats without the secure hold of the portable computer placed on it being impaired.

[0035] In a further aspect or development of the invention, the object can be seen to be to provide a device in which any change in the configuration, in particular its assembly and disassembly, can be carried out as often as desired without the use of tools and without risk of injury.

[0036] In a further aspect or development of the invention, the object can be seen as providing a robust device which can be easily folded for space-saving storage, is lightweight, is convenient to transport and / or can be produced cost-effectively.

[0037] In a further aspect or development of the invention, the object can be considered to provide a method for constructing a device for attaching a portable computer for scanning documents and arrangements of, in particular, three-dimensional imaging objects.

[0038] The object of the invention is solved by the subject matter of the independent patent claims. Dependent claims represent further developments.

[0039] By a portable (optical) communication device or user device we mean a portable computer with an integrated camera and a connection for exporting image information, such as a mobile phone or a tablet.

[0040] The invention provides a device holder for receiving a commercially available portable communications device, comprising a frame, a device receptacle enclosed by the frame for receiving the portable communications device, and at least three adjusting legs. Each of the adjusting legs has a fastening head with locking means for locking with complementary counter-locking means, wherein the counter-locking means are arranged on the frame.

[0041] The user can use the device holder to take scans of objects placed below or near the device holder on a surface, such as a horizontal tabletop, using their portable communications device. Typically, they will use their free hands during the recording process to manipulate an underlying document or move an object placed below or in front of the device holder. For example, the user can annotate an underlying document or turn the page of a book placed underneath. The device holder can be placed on a control panel that controls the light and sound in the room, and the camera can be aimed at a nearby object illuminated by an overhead spotlight. The frame, each pair of adjacent legs on the frame, and the base of the device holder define an access gap for inserting a hand under the device holder.In a configuration with only three adjustable legs, the gap can advantageously be chosen to be wide, for example, one side of the device can be completely unadjusted.

[0042] The locking elements engage with the corresponding counter-locking elements without the need for tools, allowing the configuration to be set up or modified completely autonomously, i.e., without additional measures, at any time and in any location. For example, a configuration with an access gap originally intended for a right-handed user can be adapted for use by a left-handed user if necessary.

[0043] Furthermore, the counter-locking means and the locking means are configured such that the adjustable legs can be arranged in a flexible position on the frame. This feature allows for a particularly wide selection of adjustable leg configurations, from which the user can select the most suitable one. To improve the stability of the structure, the fastening head is designed to encompass the frame.

[0044] In a particularly user-friendly embodiment of the invention, the locking means are designed to engage with the counter-locking means by pressing the adjustable legs against the frame. This connection requires no extensive technical expertise or fine motor skills. With a little practice, it can be locked and released without close inspection or with one hand.

[0045] In an advantageous embodiment of the device, the locking means comprises a locking lug for locking with a locking element on the frame, in particular for engaging in a groove provided for this purpose in the frame. The groove can be designed such that the adjustable legs can be inserted into it without overcoming any snap-in resistance. Alternatively or additionally, the adjustable legs can be moved in the groove with low friction and without snagging, so that adjustable leg configurations can be adjusted particularly easily. This facilitates finding a stable setup configuration, for example, when using three adjustable legs.

[0046] Furthermore, a frame can be provided which has an L-shaped cross-section, at least in sections. On this section, the frame forms a collar which can be used as a support strip. By means of a suitably designed interruption in the L-shaped formation, a cable feed to the portable communications device can be made possible. In another embodiment, a suitable interruption can be used to place a cover for its screen or an attached keyboard over the frame or to fold it over it. However, the image data transmission can also take place wirelessly and the frame can have an L-shaped cross-section all around.

[0047] In a preferred embodiment, the frame forms a shell for the portable communications device, which can be fitted at least partially. Alternatively or additionally, the frame has a stiffening in the form of struts that run through the bottom of the shell and stabilize the device holder. Alternatively or additionally, the struts prevent smaller portable communications devices from falling out of the device holder due to gravity. For this purpose, the struts can additionally have a surface structure that can counteract the slipping of the user device placed on it through friction effects.

[0048] In an advantageous embodiment, the fastening head has projections for gripping the frame, characterized in that the locking means are arranged on at least one of the projections.

[0049] A first projection may be longer than a second projection. Such a design may be advantageous in sections where the frame does not have a rectangular cross-section.

[0050] In an advantageous embodiment, the at least three adjustable legs have different bending angles. Alternatively or cumulatively, the adjustable legs have different lengths. These additional design options allow the access gap to be expanded in width and height. On a desk-like inclined surface, a short adjustable leg length and a large bending angle contribute to improved stability of the device holder.

[0051] One embodiment provides that two of three adjusting legs have a different length and the projections of their fastening heads have a different orientation to one another, so that the long or short adjusting legs placed on a horizontal surface hold the frame with the fastening heads surrounding the frame at an inclination to the surface.

[0052] The frame is preferably made of plastic. Alternatively or additionally, the adjustable legs are made predominantly of plastic. The projections surrounding the frame have an elasticity that facilitates sliding the locking device over the frame and locking it into the locking device. The material properties can also enable cost-effective production.

[0053] The frame and / or legs can be made of metal, either partially or entirely, for example, aluminum with a hollow interior. Alternatively, only the mounting head could be made of plastic, or the outer layer and a core structure could be made of a metal such as aluminum.

[0054] Monolithically produced components are particularly resistant to mechanical stress. A preferred embodiment therefore provides for a monolithic frame structure. Alternatively or additionally, at least one support leg is monolithic. For example, the monolithic components of the device holder can be manufactured using additive manufacturing, particularly 3D printing. A rough surface finish on frame surfaces, such as the support strip, can be achieved particularly easily in this way.

[0055] To allow the device holder to be installed on a slightly inclined surface, one design provides for the legs to have rubberized feet. Alternatively, or cumulatively, the feet are semicircular on the underside.

[0056] Alternatively or additionally, the frame forms at least a retaining collar in part. If the support surface of the device holder is held in an inclined position, such a retaining collar can protect a user device placed on it from falling due to gravity.

[0057] In an advantageous embodiment, the frame or the device holder has at least one recess or opening for accommodating adjustable legs. Alternatively or additionally, retaining lugs are provided for clamping the adjustable legs. Each of these embodiments simplifies the transport of the device holder. Alternatively or additionally, they allow for space-saving storage.

[0058] For universal use of the device holder, an insert adapter can be used for at least partial insertion into the device receptacle of a device holder, which is designed to provide a smaller or larger device receptacle. For example, such an insert adapter can reduce the size of an opening in the device receptacle so that a smaller device is securely held. Conversely, an insert adapter can be attached to the device receptacle to provide a stable device receptacle that extends beyond the frame.

[0059] A device holder is provided which is adapted to accommodate a commercially available portable communications device and comprises a frame, a device receptacle enclosed by the frame, and at least three adjustable legs. The adjustable legs are adapted to be mounted to the frame and detached from it without tools. Furthermore, the frame is adapted to offer a flexible arrangement of the adjustable legs on the frame such that the frame can be placed on the adjustable legs. The device receptacle has at least one passage opening and is adapted to accommodate the portable communications device such that the camera lens faces the device receptacle and is arranged above the passage opening.

[0060] A method for assembling a device holder is presented, comprising the following steps: Firstly, providing a frame, the frame enclosing a device receptacle and having at least two sides, then identifying a top side of the device receptacle, prepared to receive a portable communication device, further providing at least three adjusting legs and successively fastening a first adjusting leg to a first side of the frame, fastening a second adjusting leg to a second side of the frame, finally fastening a third adjusting leg to one side of the frame, such that the legs are all arranged on the side opposite the top side of the device receptacle.

[0061] In the following, the invention is described in more detail using exemplary embodiments and with reference to the figures, wherein identical and similar elements are partly provided with the same reference numerals and the features of the various exemplary embodiments can be combined with one another. Short description of the characters

[0062] It shows: Fig. 1 Detail in cross-sectional view of a frame with an L-shaped cross-section and the fastening head of a leg, which has locking lugs on the upper and lower projections, Fig. 2 Detail section in cross-section of a frame with pressed-on fastening head, Fig. 3 device holders in cross-sectional view, Fig. 4 device holders as in Fig. 1, but with long legs, Fig. 5 Device holder in cross-sectional view, in which the device holder is held in an inclined position by legs of different lengths, Fig. 6 Perspective overall view of a device holder. Detailed description of the invention

[0063] The Fig. 1 shows a detailed illustration of a preferred embodiment of a device holder 1, in which the frame 11 has a support strip 12 on its inside for placing a portable communications device 2 inserted from the top of the device holder 1. The device holder 10 thus forms a shell that is open at the top and bottom. A leg 14 runs into a fastening head 15, which has a projection 16 arranged at the top and a bottom. The frame 11 has an L-shaped cross-section. The fastening head 15 with its two projections has a C-shaped cross-section. In order to slide the fastening head 15 over the frame 11, the resistance of a locking lug 17 on each of the two projections 16 of the fastening head 15 must be overcome. In the present illustration, the locking lug 17 is only partially formed on the upper projection 16.It can be omitted entirely if necessary (advantage: the adjusting leg can then be easily levered out). The hold of the fastening head 15 on the frame 11 can be further improved by the support surface of at least one projection 16 on the frame 11 having a roughened or hatched structure. The cross-section of the frame 11 can be circumferentially different from the described shape or deviate from it in places. For example, a material recess 22 can be provided for guiding a cable with a plug to the outlet socket of the tablet. Likewise, only one of the two projections 16 of the fastening head 15 can optionally have a locking lug 17. The upper projection 16 can, for example, form a larger locking lug 17 that engages in a groove on the upper side of the frame 11.Instead of the C-shaped cross-section, the fastening head 15 can also have an L-shaped cross-section, wherein the upper projection 16 can be formed as a locking lug 17 that engages in a groove on the side surface of the frame 11, while the lower projection 16 supports the frame 11. The lower projection 16 can additionally have a locking lug 17 for engaging behind the frame 11. The locking lugs 17 improve the hold of the adjusting legs 14 on the frame 11 compared to the plug-in connection.

[0064] The Fig. 2 shows in lateral cross-section a frame 11 and a fastening head 15 as in Fig. 1, wherein the fastening head 15 with its two projections 16 encompasses the frame 11. The lower projection 16 projects beyond the upper projection 16 in such a way that when the fastening head 15 is pushed over the frame 11, its two locking lugs 17 engage in the upper and lower openings of the shell, respectively, thus strengthening the connection.

[0065] The Fig. Figure 3 shows a cross-section of a device holder 1. It comprises the frame 11 and the adjustable legs 14 in a standard length. The design of the frame 11 and the two adjustable legs 14 shown corresponds to those of the Fig. 1 and Fig. 2. A tablet is inserted into the opening of the shell formed by the frame 11 with an essentially precise fit. The adjustable legs 14 are monolithic. At their lower end, they have semicircular feet 18 so that they can also stand on a slightly inclined surface. For better grip, the feet 18 could also be provided with a profile. Alternatively or additionally, the slip resistance of the feet 18 can be ensured by choosing a suitable material, such as hard rubber. A support surface beneath the device holder 10 is delimited by the contact positions of the feet 18 on the support surface. The tablet is inserted into the device holder 10 such that its camera faces the support surface, but is not arranged symmetrically between the two adjustable legs 14, so that its field of view 21 does not completely cover the support surface.On the side of the frame 11 closest to the camera, the field of view 21 extends beyond the support surface, so that a leg 14 is captured by the field of view 21. This leg 14 can, if necessary, be moved in a groove in the frame 11 to the edge of the field of view 21 or it can be detached from the frame 11. Alternatively or additionally, it can be digitally removed from the resulting image data using suitable software. However, the leg 14 can also perform an additional function or a function independent of its static function. For example, it can support, fix, or help conceal an object 3 being photographed. For example, a leg 14 can be used to hold down a book page by attaching the respective leg in a suitable position.

[0066] Referring to the Fig. 4 shows a device holder 1 with a tablet inserted into the device holder 10, which comprises the structure Fig. 3, but is equipped with a pair of longer legs 14. The camera of the tablet is in a position similar to that shown in Fig. 3. Due to the longer legs 14, however, its field of view 21 now covers the entire surface. This allows Fig. 3 larger objects 3 can be captured. Alternatively or cumulatively, the longer legs 14 facilitate access to a recording object 3 below and in front of the device holder 10.

[0067] The Fig. Figure 5 shows a device holder 1, the frame 11 of which is held at an angle by a pair of legs 14 of different lengths. Since the tablet is secured against slipping out by the lower edge of the tray at the angle shown, this construction represents a Fig. 4 represents an alternative method of moving the field of view 21 out of the support surface. In this way, objects 3 can be photographed from an oblique top view, which also reveals their vertical extent. This configuration also allows particularly convenient access to the object 3 being photographed. The legs 14 differ from those of the Fig. 1 and Fig. 2 in that the projections 16 of their fastening heads 15 define a different holding angle relative to the respective adjusting leg 14. Provided the feet 18 are sufficiently non-slip, legs 14 of different lengths can also be placed on a desk-like inclined surface and hold the frame 11 in a preferably less inclined position. Depending on the weight of the portable communication device 2, adjusting legs 14 with a larger bending angle should be selected for the frame edges opposite one another in the direction of inclination, which expand the corresponding engagement gap and thus contribute to secure standing.

[0068] The Fig.6 shows a device holder 1 in perspective view with four adjusting legs 14, wherein two adjusting legs 14 each have a first length and two further adjusting legs 14 have a second length. Each adjusting leg 14 runs into a fastening head 15 with a pair of projections 16 of different lengths, of which the lower projection 16 is longer than the upper projection and has a locking lug 17. The frame 11 of the device holder 1 has a substantially L-shaped cross-section, which is encompassed on the outer frame flank by the fastening heads 15 of the four adjusting legs 14, while on the inner side of the frame 11 it forms a circumferential support strip 12 for supporting an electronic device 3. The locking lug 17 of the longer projection 16 engages behind the frame 11 from below. The support bar 12 and two struts 19 stabilizing the frame 11 form a device holder 10 which has the passage opening 13.On the frame side, which is arranged in the foreground of the figure, the frame 11 has a recess 22 for a cable feed to the electronic device 3.

[0069] The legs 14 or the frame 11 can be configured to hold a small lamp for illuminating an object 3. It can be advantageous to use multiple light sources, particularly when photographing an array of objects 3 or during dynamic processes. Alternatively or additionally, a leg 14 can support cable routing, for example, when setting up an experiment.

[0070] In order to modify web pages or digitally available documents as conveniently as a sheet of printed paper, an overlay app can be used to combine the image data created by the user on the device holder 1 with the digital image data during his presentation.

[0071] It will be apparent to those skilled in the art that the embodiments described above are to be understood as examples and that the invention is not limited to them, but can be varied in many ways without departing from the scope of the claims. Furthermore, it is clear that the features, regardless of whether they are disclosed in the description, the claims, the figures or otherwise, also individually define essential components of the invention, even if they are described together with other features. In all figures, the same reference numerals represent the same objects, so that descriptions of objects that may only be mentioned in one or at least not with regard to all figures can also be transferred to these figures and exemplary embodiments with regard to which the object is not explicitly described in the description.
