Description

Technical Field

[0001] The invention relates to a film projection device having (a) at least one film display device, (b) a plurality of seats for spectators, and (c) a movement device comprising at least five linear drives, by means of which the seats can be moved together in at least five degrees of freedom, at least one of which is fixed to a swivel arm and at least two of which are fixed in an immovable manner at corresponding base points, and (d) a base element, to which the seats are fixed so that they can be rotated and which, by activating the movement device, can be brought from a first docking position into a projection position, wherein in the first docking position the base element can be docked at an entry point, and in the projection position the base element is rotated through a rotation angle of at least 15° relative to its first position. Background Art

[0002] Such a film projection device is known from DE 10 2011 122 229 A1 and provides a simple way to move spectators to a position where they can watch the film particularly comfortably. The function of this system has proven to be effective, but it still has the disadvantage that its construction, installation and / or maintenance may be relatively complex. Summary of the invention

[0003] The object of the present invention is to alleviate the disadvantages of the prior art.

[0004] The invention solves this problem by means of a film projection device according to the preamble, the base element of which can be brought from a docking position into a projection position by swiveling the arm upwards.

[0005] The present invention also solves this problem by means of an audience module for such a movie projection device, which has (a) a plurality of seats for the audience and (b) a moving device, (i) the moving device includes at least five linear drives, by means of which the seats can be moved together in at least five degrees of freedom, (ii) at least one of the linear drives is fixed to a rotating arm, and (iii) at least two of the linear drives are fixed in an immovable manner at corresponding base points, and (c) a base element, (i) the seats are fixed to the base element so that they can be rotated, and (ii) the base element can be brought from a first docking position into a projection position by activating the moving device, wherein in the first docking position the base element can be docked at an entry point, and in the projection position the base element is rotated relative to its first position through a rotation angle of at least 15°, wherein the docking position of the base element can be brought into the projection position by rotating the arm upwards.

[0006] According to another aspect, the present invention solves this problem by a method for projecting a film with the aid of a film projection device, the film projection device comprising (a) at least one film display device and (b) an audience module according to the present invention, the method comprising the following steps: activating the movement device by rotating the arm upwards so that the base element is (i) brought out of a first docking position, wherein in this first docking position the base element is docked at an entry point, and (ii) brought into a projection position, wherein in this projection position the base element is rotated through a rotation angle of at least 15° relative to its first position.

[0007] An advantage of the invention is that each spectator can be moved such that: it creates a realistic illusion that each spectator himself is experiencing what is happening in the movie; this is particularly true if the linear drive forms a hexapod drive, which is the case according to a preferred embodiment of the invention.

[0008] It is also advantageous that the moving device can be constructed more simply than in previous solutions. In this way, simply by moving the swivel arm, the swivel arm causes the movement of the spectator's seat to a large extent, thereby moving the spectator from the docking position where the spectator can sit to the projection position where the spectator can watch the movie. Unlike the prior art solutions that provide for the six-legged drive to be completely fixed to the rocker arm, the arm does not need to withstand all forces and torques; instead, this solution only needs to withstand those forces and torques applied by the linear drive fixed to the swivel arm. Other forces can be directly guided to the structure to which the moving device is fixed via the base point of the corresponding linear drive. In addition, the requirements for this structure are lower, because the forces to be applied locally are generally smaller than those in known systems. Advantageously, the linear drive is arranged in such a way that the force transmitted via the swivel arm is smaller than the force not transmitted via the swivel arm. Preferably, the force transmitted via the swivel arm is as small as possible.

[0009] According to a preferred embodiment, the movie display device is characterized by (a) at least one projection screen and (b) at least one projector, the projector being configured to project the movie onto the projection screen.Such a system is generally easy to expand and is generally relatively easy to produce.

[0010] Alternatively or additionally, the movie display device may have an LED screen or another type of self-luminous screen. The LED screen may be curved, in particular spherical; however, this is not essential.

[0011] Within the scope of the present description, a projection surface is to be understood in particular as meaning a light-colored (eg white) flat surface or a curved surface, allowing a film to be projected onto a projection screen.

[0012] A projector is to be understood as meaning in particular a device by means of which a rapid sequence of at least 15 different images (movies) per second can be projected onto a projection surface. The projector may consist of several individual projectors which illuminate different parts of the projection surface. Projectors of this type, which consist of several individual projectors, are used as standard equipment in 3D cinemas.

[0013] It is possible and feasible to design the film projection device so that it can accommodate at least 4, in particular at least 12, preferably at least 20 spectators. In other words, it is advantageous that there are at least 4 but in particular at least 20 seats available for the spectators. The film projection device is preferably designed to accommodate a maximum of 120 spectators.

[0014] A movie should be understood to mean a predefined sequence of images, as is the case with conventional cinema movies. Alternatively, the movie can be determined interactively. In this way, the movie projection device can be a flight simulator. The movie projection device preferably has a processing unit connected to the control device. If the control device is activated, the processing unit calculates the reaction that the aircraft will show in the case of a corresponding activation of the control device, and calculates the image projected by the projector onto the projection surface and the control signals for the mobile device. The audience in the seat has a feeling that they are sitting in an aircraft controlled by the control device. In addition to simulating an aircraft, any other type of aircraft can also be simulated, such as a flying object (such as a helicopter, a rotorcraft, a rocket) or a car (such as a virtual car on a virtual road) or a ship.

[0015] For example, in the docking position, the base element can dock directly at the outlet. The outlet is preferably an immovable part of the construction. This results in the system requiring less installation space. Such a construction with a film projection device according to the invention is another subject of the invention.

[0016] Alternatively, when in the docked position, the base element may dock at a docking station, which docking station forms part of a cinema projection apparatus according to a preferred embodiment of the invention. Preferably, the docking station can be moved away from the base element. This has the advantage that the envelope of movement is free and that the movement can preferably be performed in all degrees of freedom from the docked position.

[0017] The movie projection device is preferably designed to show the movie in a feedback-free manner. In other words, the movie and the movement of the audience seats are performed using a predetermined sequence of images and movements. In other words, the movie projection device is preferably not a simulator. With a simulator, the images shown depend on input from a person who is usually trained with the aid of a simulator. Such simulators are very complex to produce and are therefore expensive. Therefore, they are generally not well suited for entertaining large numbers of people.

[0018] The feature that the seats can be moved together in at least five degrees of freedom is to be understood as meaning in particular that the seats are coupled relative to one another in at least five degrees of freedom. For example, the seats are coupled to one another in three translational degrees of freedom. This applies in particular to the case where all seats are attached to a base element. If this base element is moved translationally in a spatial direction, all seats are moved in the same direction by the same amount.

[0019] Advantageously, the seats are mounted such that they can rotate about at least one seat rotation axis. The swivel arm is mounted such that it can rotate about the arm rotation axis. It is particularly advantageous if at least one seat rotation axis extends at least predominantly parallel to at least one arm rotation axis.

[0020] The feature that the axes of rotation extend predominantly parallel to one another is understood to mean that although the axes of rotation may extend parallel to one another, the two axes of rotation may also together form an angle of less than, for example, 10°. This has the advantage that the rocker arm can be activated and the seat can be moved in the opposite direction without any rotational acceleration of the seat.

[0021] According to the invention, the film projection device has an access point by means of which the spectators can reach the seats, wherein the movement device comprises a base element to which the seats are attached so that they can be rotated. This results in a particularly simple construction.

[0022] Advantageously, by activating the swivel arm, the movement device can be brought into a docking position, in which the base element is docked at the entry point, and into a projection position, in which the base element is inclined by a rotation angle of at least 15° relative to its first position. In the second position, the base element is usually located further away from the entry point than in the first position. From this position, a variety of movements can then be performed with the movement device, which preferably forms a hexapod drive.

[0023] The docking position can be described as an intermediate position that allows the audience to change. The projection position can be described as a working position where the audience can watch the movie and be moved.

[0024] The seats are preferably arranged on the base element such that when the mobile device is in the docking position, at least one third of the persons sitting on the seats have at least one seat in their field of vision; when the mobile device is in the projection position, the number of persons having at least one seat in their field of vision changes to at most one tenth of the persons sitting on the seats. Field of vision is to be understood in particular as meaning the human binocular field of vision with a horizontal range of ±10°, a positive upward vertical range of +25° and a negative downward vertical range of -35°.

[0025] The field of vision, which can be defined as the field of focus, defines the area in line with all observed objects in the external space, over which the eye can be directed with a continuous central focus. When in projection position, if up to one in ten people sitting in a seat (especially people of short stature) have another seat in their field of vision, this person has the impression that they are completely alone in the room, which creates a particularly intense experience.

[0026] Advantageously, the base element can be rotated by at least 20°, in particular at least 30°, solely by means of the swivel arm.

[0027] Preferably, the base element can be rotated by at least 25°, in particular at least 30°, relative to the rotational movement about the arm's rotation axis by means of the hexapod drive. It is also advantageous if the base element can be rotated by at least 60°, in particular at least 70°, by means of both the arm and the hexapod drive. 90°±25° has proven to be particularly advantageous. The base element can preferably be rotated by at most 180° by means of the arm and the hexapod drive together.

[0028] According to a preferred embodiment, the hexapod drive comprises at least six linear drives, each of which has a minimum length position, a maximum length position and a hub, wherein when the movement device is in the first position, at least one linear drive has moved its hub at most 75% out of the minimum length position. In the docking position, at least five (but in particular six) linear drives are preferably retracted by at least 75%. The swivel arm and its swivel drive are then preferably in their end positions.

[0029] A linear drive is to be understood in particular as meaning a drive which can generate compression and tension forces. A linear drive can also be a telescopic drive and be constructed with one, two or more stages. In particular, a linear drive comprises a hydraulic cylinder or a ball screw drive.

[0030] In order to achieve the largest possible angle between the docking position and the projection position, it is advantageous for the mobile device to assume an extreme position or to be in the vicinity of an extreme position when the mobile device is in the first position. This means that at least one linear drive is almost in its maximum length position. The maximum length position describes the position of the linear drive at its maximum length. Correspondingly, the minimum length position describes the position of the linear drive at its minimum length. The hub is the length difference between the length when in the maximum length position and the length when in the minimum length position.

[0031] It is also advantageous that all actuators do not have to consume energy in the first position, so that they only have to be switched off when necessary for safety reasons, rather than having to use external energy to bring the base element into a stable position or having to stop or brake it.

[0032] It is possible that the base element is in a stable position when in the docking position. This means that it will not leave the docking position unless it is supplied with energy. In this case, braking is not necessary.

[0033] Most seats preferably have a retaining device by means of which a person can be fixed relative to the seat. This may be a retaining bracket; alternatively or additionally, the retaining device may include a seat belt. The retaining device may be necessary to prevent a person from falling out of the seat and injuring themselves.

[0034] According to a preferred embodiment, the projection screen is curved and most of the seats are arranged in an imaginary fitting sphere passing through the projection surface. The fitting sphere should especially be understood to mean a mathematically defined fitting sphere, i.e. for which the integral of the deviations between the imaginary sphere and the projection sphere is minimal.

[0035] Advantageously, the seat can be automatically rotated relative to the floor element. In other words, in particular a rotary drive can be provided, by means of which the seat can be automatically rotated. This has the advantage that, if necessary, the rotary movement of the base element can be counter-balanced. It is possible, but not necessary, for each seat to have its own rotary drive. Instead, two or more seats can also be driven by the same rotary drive.

[0036] According to a preferred embodiment, the film projection device has a control unit which is designed to automatically execute a method characterized by the following steps: (i) identifying whether a release signal for moving a mobile device is present for all seats occupied by persons, wherein the signal is used to provide a code for the situation in which the person occupying the seat is fixed relative to the seat, (ii) if a release signal is present, rotating the rotating arm so that the mobile device moves to the projection position, (iii) projecting the film and synchronously moving the spectators' seats, in particular by moving the spectators' seats by means of the mobile device moving the base elements to which the seats are attached.

[0037] The control unit is preferably configured to automatically perform a method, the method being characterized by the additional steps of: rotating the swivel arm so that the moving device is moved into the docking position; and releasing the holding device.

[0038] According to a preferred embodiment, the linear drive fixed to the swivel arm forms a kinematic chain together with the swivel arm. As a result, the linear drive always moves when the arm moves. In contrast, at least two linear drives immovably fixed to respective base points are independent of the arm. This means that a first movement of the arm does not necessarily lead to a movement of the linear drive, and a movement of the linear drive does not necessarily lead to a movement of the arm.

[0039] Alternatively, the rocker arm can also be designed such that: the base points of one, two or three linear drives are fixed to the rocker arm, wherein the base points of the remaining linear drives cannot be moved by means of the rocker arm; instead, the base points of the remaining linear drives are fixed, for example, to the structure. In other words, the components of the hexapod drive can be moved by means of the rocker arm.

[0040] The movie projection device preferably has an entry point, which enables the audience to reach the base element so that they can reach the seats. In the docking position, the base element docks at the entry point.

[0041] Preferably, one of the linear drives, designated as the first linear drive, is fixed to the swivel arm at a first arm-base point and to the base element at a first base element-base point, wherein the first base element-base point is higher than the base points of the at least four other linear drives when the base element is in the projection position. This means that the linear drive has to absorb relatively small forces and can be designed to be as light and simple as possible.

[0042] It is also advantageous if the movement device has a second linear drive which is fixed to the swivel arm at a second arm base point and to the base element at a second base element base point, wherein the second base element base point is higher than the base points of the at least four other linear drives.

[0043] It is particularly possible that, in the projection position, the first linear drive extends at a first angle of at most 30°, in particular at most 20° and / or at least 4° relative to the horizontal plane. Alternatively or additionally, in the projection position, the second linear drive extends at a second angle of at most 30°, in particular at most 20° and / or at least 4° relative to the horizontal plane.

[0044] The third linear drive and the fourth linear drive preferably extend at a third angle or a fourth angle in the projection position, which third angle or the fourth angle preferably extends between 10° downwards and 20° upwards relative to the horizontal plane.

[0045] The fifth linear drive and the sixth linear drive preferably extend at a fifth angle or a sixth angle in the projection position, which fifth angle or sixth angle preferably extends between 40° and 60° relative to the horizontal plane.

[0046] It is possible that, when in the projection position, the designated fifth linear drive of the movement device extends at a fifth angle of at least 40°, in particular at least 45°, relative to the horizontal plane.

[0047] When in the projection position, the linear drives preferably extend between 50% ± 15% of the respective hubs with the arms rotated upward.

[0048] Alternatively or additionally, it is possible that the movement device has a so-called sixth linear drive which, when in the projection position, extends at a sixth angle of at least 40°, in particular at least 45°, relative to the horizontal. This angle is in the range between minus 90° and plus 90°. If the fifth angle is indeed of a given size, this results in the fifth linear drive absorbing a large part of the weight of the base element and of the seats and the audience. In general, the greater the fifth angle, the smaller the forces acting on the fifth linear drive. The same applies to the sixth angle and the sixth linear drive.

[0049] It is particularly advantageous if the fifth linear drive and the sixth linear drive are arranged mirror-symmetrically to one another. Within the scope of the invention, a mirror-symmetrical arrangement should be understood to mean a mirror-symmetrical arrangement in the technical sense. This means that it is possible, but not necessary, for the drives to be arranged mirror-symmetrically to one another in a strict mathematical sense. Rather, it is sufficient if the linear drives are arranged functionally mirror-symmetrically to one another.

[0050] The swivel arm preferably comprises a swivel drive. This may refer to a rotary drive, in particular an electric motor connected to the arm via a gearbox. Alternatively, it may refer to a linear drive acting on the swivel arm.

[0051] Advantageously, the swivel arm can be locked in the projection position. In particular, in this case, a locking device has been provided. A locking device should be understood to mean a device which prevents the swivel arm from moving independently of the drive. If a locking device has been provided, the forces introduced into the drive are generally smaller, so that the drive can be constructed to be weaker, which is feasible.

[0052] All elements that move when the base element is moved from the locking position to the projection position have a common center of mass. There is a center of mass function that relates the height of the center of mass to a predetermined rotation angle of the rotating arm. The height is understood to mean the physical height, i.e. an increase in height results in an increase in potential energy.

[0053] Advantageously, the center of gravity function has a local minimum. It is particularly advantageous if there is only one local minimum. In this case, the base element is mounted bistable, wherein a global minimum of the potential energy of the element moved during the movement of the base element is achieved when the base element is in the docking position, and another energy minimum is achieved when the base element is in the projection position. This has the advantage that a relatively small amount of potential energy is released during the movement from the docking position to the projection position. This in turn makes it relatively easy to move the mobile device out of the projection position and back into the docking position in the event of a drive failure, for example during a power outage.

[0054] The rotation angle at which the center of gravity function has a local minimum is known as the maximum height rotation angle. The rotation angle at which the base element is in the docking position is known as the docking rotation angle. The rotation angle at which the base element is in the projection position is known as the projection rotation angle. It is feasible that the maximum height rotation angle is within a tercile between the docking rotation angle and the projection rotation angle (including the projection rotation angle).

[0055] When the base element is in the projection position, the center of mass is at the projection height. When the base element is in the docking position, the center of mass is at the docking height. Advantageously, the difference in subsidence height between the height of the local maximum and the projection height is at most twice the difference in mid-height between the height of the local maximum and the docking height. As a result, in the event of a power outage, it is easier to move the base element out of the projection position and back into the docking position.

[0056] Preferably, the movie projection device is characterized in that it comprises a manually activated emergency drive. The emergency drive can preferably be used to move the base element into the docking position; in particular, to move it out of the projection position into the docking position. The emergency drive can be, for example, a crank device. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Hereinafter, the present invention will be explained in more detail by means of the accompanying drawings.

[0058] Figure 1 By part Figure 1 a, 1b and 1c show a film projection device with its base element brought from a docking position into a projection position,

[0059] Figure 2a a perspective view showing the mobile device and the base element in a docked position, and

[0060] Figure 2b The mobile device and the display position are shown Figure 2a base element.

[0061] FIG3 shows the centroid function. DETAILED DESCRIPTION

[0062] Figure 1 a depicts a film projection device 10 having a projection surface 12, a projector 14, a plurality of seats 16.1, 16.2, ... for spectators 18.1, 18.2, ..., a base element 20 and a moving device 22. The projector 14 is arranged to project a film onto the projection surface 12. The seats 16.i (i = 1, 2, ...) are arranged around respective rotation axes D 20 The seats are rotatably mounted on a base element 20. It is possible that a group of at least three and preferably at most 20 seats can be rotated about the same respective axis of rotation D.

[0063] The movement device 22 comprises six linear drives 24.j, which together form a hexapod drive. In other words, by activating the linear drives 24.j, the base element 20 can be moved in three translational degrees of freedom and three rotational degrees of freedom.

[0064] The moving device 22 is characterized by a rotating arm 26, linear drives 24.1, 24.2 (see Figure 2b ) is fixed to the swivel arm. The arm 26 is fixed in a pivot bearing 28 on a foundation 30. It should be noted that the term "foundation" does not necessarily mean that there must be direct contact with the ground. For example, the foundation can also be formed by a part of the construction. The only decisive factor is that the foundation is stable enough to be able to withstand the forces that occur during operation of the mobile device 22.

[0065] Figure 1 As shown in a, the movie projection device 10 may include an entry point 32, by means of which the audience 18.i can reach the seat 16.1. Figure 1 In FIG. 1 , the base element 20 is shown in a docking position in which it docks at the access point 32. It is possible, but not necessary, for the base element 20 to be designed such that it forms a positive locking connection with the access point 32. It is particularly feasible that the movement device 22 is designed such that the base element 20 is pressed against the access point 32 even if the energy supply has failed.

[0066] This can be achieved, for example, by ensuring that the center of mass S moves upwards when the base element 20 leaves its docking position. Figure 1 All elements in the projection device depicted in c are moving, and the movement of the elements contributes to the change of potential energy.

[0067] Figure 1c depicts the base element 20 in its projection position, in which the audience 18.i can watch the projected film. It will be appreciated that the arm 26 has been pivoted about the arm axis D by means of the pivot bearing 28. 26 Rotated by a rotation angle α. When the base element 20 is in Figure 1 In its docked position shown in a, the rotation angle α is considered to be zero. The rotation angle α is always measured as a positive value.

[0068] Figure 1 b shows the base element 20 in an intermediate position between the docking position and the projection position.

[0069] Figure 2a The mobile device 22 and the base element 20 are depicted in a docked position. It will be appreciated that the first linear drive 24.1 is fixed to the arm 26 at a first arm base point 34.1 and to the base element 20 at a base element base point 36.1. Accordingly, each linear drive 24.j has an arm base point 34.j and a base element base point 36.j.

[0070] Figure 2b It is shown that when the base element 20 is in the projection position, the first base element base point 36.1 and the second base element base point 36.2 are located above all other base element base points.

[0071] Each linear drive has a longitudinal axis Lj along which it extends or shortens during operation. j The angle between the horizontal plane H and the j It should be noted that, for example, when the base element 20 is in its projection position, the second angle β2 is less than 20°. The same applies to the angles β1, β3 and β4. In contrast, the sixth angle β6 and the fifth angle β5 (not depicted here) are greater than 45°; in the present case, β6=55°.

[0072] In the present case, the arm 26 is driven by a rotary drive 38, which is schematically depicted in the form of a hydraulic cylinder. Alternatively, the rotary drive 38 can also comprise a threaded electric motor.

[0073] Figure 3a The center of gravity function F is plotted, which assigns the height H to the rotation angle α, where the center of mass S (see Figure 1 a) is located at the corresponding rotation angle α. It should be noted that the center of gravity function F passes through the local maximum M(α M / H M ). The maximum rotation angle α of the centroid function F passing through the local maximum M Located in the lateral third of the docking position T1.

[0074] It should be appreciated that the center of gravity function F is constant at the rotation angle α0 = 0° (docked position) and the maximum rotation angle α max There are two global minima at (screening position). In the current case, α max =100°; however, this value may be larger or smaller.

[0075] Butt height difference Δ1 = H M -H A is the maximum height H M Height H to docking position A =H(α0) The difference between the projection height Δ2 = H M -H V is the maximum height H M The projection height H of the projection position V =H(α max ). In the current case, the docking height H A Greater than projection height H V , which represents a preferred embodiment and is independent of other properties of this embodiment.

[0076] Figure 3b The center of gravity function of another embodiment of the present invention is shown; here, the local maximum is located in the third of the projection position side T3. In this case, the docking height H A Less than projection height H V , which represents a preferred embodiment, regardless of the other properties of this embodiment. This embodiment has the advantage that it is particularly easy to move the base element 20 to the docking position if the moving means fail. This is particularly true when the docking height difference Δ1 (as shown in the present case) is greater than the projection height difference Δ2; however, this is optional.

[0077] Figure 3c The centroid function of another embodiment of the invention is shown; here, the local maximum is located in the central third T2. The projection height difference Δ2 differs from the insertion height difference Δ1 by less than 15%, which represents an alternative preferred embodiment, regardless of the other properties of this embodiment.

[0078] Figure 1 a depicts an emergency drive 40 in the form of a crank device, characterized by a cable fixed to the free end of the arm 26. The cable is wound on a drum, which is pretensioned by a spring in the winding device so that the cable is permanently tensioned. In the event of failure of the moving device 22, if the rotation angle α is greater than α M (See Figure 3) The base element 20 can then be moved back to its docking position by rotating the drum using the hand crank.
