[0003] Pendulum device

[0004] The invention relates to a pendulum device according to the features of the preamble of claim 1.

[0005] Such a pendulum device is known, for example, from DE 202021 003 470 U1. This patent describes a pendulum device for coupling to a piece of furniture. The pendulum device comprises a shelf mounted on a horizontal axis and a pendulum with a counterweight. The position of the shelf can be adjusted via the pendulum.

[0006] Furthermore, a combination piece of furniture with a pendulum device is known from DE 102014 015 514 A1. The pendulum device can be attached to a combination piece of furniture and in turn supports an adjustable shelf to enable comfortable working in a sitting, lying, or reclining / sitting position.

[0007] In practice, such pendulum devices are used, for example, to enable ergonomically favorable, i.e., back-friendly work, by making the work surface of the tray optimally adaptable to the sitting position, a reclining-sitting position, or a lying position.

[0008] The invention is based on the objective of creating a pendulum device for furniture that enables an ergonomic working position and is structurally simple and mechanically stable. In particular, the pendulum device should be cost-effective to manufacture. Preferably, the mechanical stability and operational reliability of a pendulum device should be improved while maintaining a space-saving design or slim dimensions.

[0009] This problem is solved according to the invention by a pendulum device with the features of claim 1.

[0010] The invention relates to a pendulum device comprising a pendulum with a horizontal pendulum axis and with a horizontal axis of a shelf arranged in the upper end region of the pendulum and with a counterweight arranged in the lower end region of the pendulum, further comprising a receiving device and / or coupling device connectable to a piece of furniture for connecting the pendulum device, in particular the pendulum axis, to the furniture, wherein the pendulum comprises a first pendulum rod extending from the horizontal pendulum axis to the upper end region, which is connected to the pendulum axis by means of a first fastening device and to the horizontal axis of the shelf by means of an upper fastening device, and wherein the pendulum comprises a counterweight extending from the horizontal pendulum axis to the lower end region, which is connected to the counterweight in the lower end region.The essential feature is that the pendulum has a second pendulum rod extending from the horizontal pendulum axis to the upper end region, which, together with the first pendulum rod, supports the horizontal axis against the pendulum axis, that the first pendulum rod and the second pendulum rod are connected to each other in such a way that they form a force parallelogram in order to enable a torsion-free support of the horizontal axis of the shelf, with the second pendulum rod being arranged parallel and spaced apart from the first pendulum rod.

[0011] The advantage of the second pendulum rod is that it provides improved support for the shelf. In particular, it stiffens the pendulum, thus reducing twisting. This results in the shelf's horizontal axis being supported with less twisting. This is achieved by placing a second pendulum rod parallel to and spaced apart from the first, and by connecting both rods to form a parallelogram of forces. This parallelogram distributes the forces in such a way as to minimize twisting of the horizontal axis, leading to more stable and reliable support for the shelf.

[0012] In particular, the inventive concept realizes a pendulum in which a second pendulum rod extends from the horizontal pendulum axis to the upper end region, parallel to and spaced apart from a first pendulum rod. Both rods support the horizontal axis of the shelf against the pendulum axis and are connected to form a force parallelogram to enable torsional rigidity. An advantage of this is that it achieves a very stable and torsionally rigid support of the horizontal axis without increasing the wall thickness or dimensions of the pendulum arm. Specifically, the arrangement of the two pendulum rods as a force parallelogram allows for improved force absorption and increased rigidity while maintaining a slender design. Furthermore, relatively small cross-sections and / or wall thicknesses can be used for the pendulum rods, yet high rigidity can still be achieved.This allows for a space-saving and structurally simple design of the pendulum.

[0013] Preferably, the counterweight is slidably mounted on the pendulum. The counterweight can be moved along the pendulum by means of a lower mounting device and locked in an adjustable position, preferably by clamps or screws. This allows the lever arm of the counterweight to be varied, and the resulting restoring force to be individually adjusted. Thus, it is possible to set different restoring forces with one and the same counterweight and to expand the application range of the pendulum device without having to replace the counterweight. Of course, the counterweight can also be replaced with a lighter or heavier one to obtain a smaller or larger restoring force.

[0014] The mounting device can be attached to a piece of furniture. It can also be designed to be attached to a stand, a frame (preferably a tripod), a column, or a wall. This allows the pendulum device to be used not only in homes or offices, but also, for example, in production halls.

[0015] The inventive concept also encompasses a combination piece of furniture comprising a pendulum device according to one of the embodiments described herein, as well as a piece of furniture. The pendulum device is attached to the furniture via its receiving device, in particular by screwing or clamping. The pendulum device is connected to the receiving device by means of the coupling device, for example, by means of a detachable connection.

[0016] This allows for the creation of a pendulum device or piece of furniture that offers a user an ergonomically versatile and adjustable workspace. The user can, for example, use a laptop, a book, or a writing surface on the shelf of the pendulum device. By pivoting the pendulum device and rotating the shelf around its horizontal axis, the work surface can be adjusted to suit the user's needs.

[0017] It is advantageous if the furniture has a padded surface beneath the shelf.

[0018] has a leg rest, so that a user can use the inventive

[0019] The pendulum mechanism can be used while sitting, lying down, or in a sit-lying position. In principle, a user can adjust the pendulum mechanism to use it in any position between standing and lying down. This ergonomic adjustment of the work surface allows for relaxed working and minimizes strain on the cardiovascular system, spine, and back.

[0020] Preferably, the pendulum axis of the pendulum is understood to be a horizontally running axis about which the pendulum is pivotably mounted.

[0021] Preferably, the horizontal axis of the shelf is understood to be a horizontally arranged axis about which the shelf can be pivoted.

[0022] Preferably, a tray is understood to be a work surface or a surface on which, for example, a tablet computer, a book, or a writing or drawing portfolio can be placed for writing or drawing.

[0023] Preferably, the term "furniture" is understood to mean a rolling container, or a bed, or an armchair, or a deck chair, or a frame, or a tripod, or a column, or a wall, or similar.

[0024] The pendulum is designed with two pendulum rods in its upper section, which together support the horizontal axis of the shelf against the pendulum axis. The two pendulum rods are connected to each other in such a way that they form a kind of parallelogram of forces. This allows for torsion-resistant support and mounting of the shelf's horizontal axis. This creates a stable work surface on the shelf and also allows the shelf's load-bearing capacity to be increased. In particular, torsion of the shelf's suspension under heavy loads can be avoided or at least reduced. As a further advantage, smaller or simpler profiles can be used for the pendulum rods, thus reducing the design complexity. The second pendulum rod is arranged parallel to and spaced apart from the first.The size of the resulting parallelogram of forces can be adjusted by changing the distance between the pendulum rods, achieving a good compromise between the required installation space and mechanically improved support of the shelf.

[0025] In one embodiment, the first pendulum rod and the second pendulum rod can be arranged on the same side of the pendulum axis. This further increases the stiffness of the pendulum and allows for a particularly slender design.

[0026] In an alternative embodiment, the first and second pendulum rods can be arranged on opposite sides of the pendulum axis, or the pendulum axis can be positioned between the two pendulum rods. This can further increase stiffness and improve the pendulum's absorption of inclined forces.

[0027] Depending on the arrangement of the pendulum rods relative to the horizontal axis, improved lateral support can also be achieved, so that lateral torques around the vertical axis of the pendulum can also be absorbed via the two pendulum rods.

[0028] In an advantageous embodiment, the pendulum may include a third pendulum rod extending from the horizontal pendulum axis to the upper end region, which, together with the first and second pendulum rods, supports the horizontal axis against the pendulum axis. This allows for a further improvement in the support of the shelf or an improved stiffening of the pendulum. For example, the first and third pendulum rods may be arranged along the same side of the pendulum axis, and the second pendulum rod along the opposite side, or the pendulum axis may be arranged between the three pendulum rods.The first fastening device can connect the first pendulum rod and the second pendulum rod to the horizontal pendulum axis, or the first fastening device can connect the first pendulum rod, the second pendulum rod and the third pendulum rod to the horizontal pendulum axis, in particular by frictional connection.

[0029] Preferably, the upper fastening device can be provided to connect the first pendulum rod and the second pendulum rod to the horizontal axis of the shelf, or to connect the first pendulum rod, the second pendulum rod and the third pendulum rod to the horizontal axis of the shelf, in particular by frictional connection.

[0030] In an advantageous embodiment, the compensating rod can be arranged at a distance from the first pendulum rod. Preferably, the pendulum has a compensating rod that connects the first pendulum rod to the compensating rod, and in particular, the compensating rod runs coaxially to the pendulum axis.

[0031] In particular, the counterweight and the first pendulum rod can be arranged at a distance from each other, allowing furniture to be positioned between them. This offers the advantage that the pendulum device can be positioned, for example, on a bed, a rolling container, or an armchair, in such a way that as little space as possible is required for the device on one side, and the counterweight is routed across or through the furniture to be attached on the other side. Such a solution is particularly advantageous in confined spaces.

[0032] To extend the application range of the pendulum device, it can be provided, for example, that a tablet can be arranged on the pendulum axis, in particular on the compensating rod, such that the shelf is arranged on the side of the pendulum facing a piece of furniture and the tablet is arranged on the side of the pendulum facing away from the furniture.

[0033] In a structurally simple design, the first pendulum rod and the counterweight rod can be formed as a single piece. This means that the pendulum rod runs linearly from the horizontal axis of the shelf, along the pendulum axis, to the counterweight and is formed as a single, continuous rod. This allows for a particularly simple design of the pendulum device.

[0034] In an advantageous embodiment, the first and second pendulum rods may be formed from the same cuttable tubular profile, or the first, second, and third pendulum rods and / or the compensating rod may be formed from the same cuttable tubular profile. The pendulum rods may be formed from profiles with a round or square cross-section. In particular, the profiles may have the same diameter or the same side dimension.

[0035] In particular, the pipe profiles or pipe sections are made of aluminum, especially with an anodized surface. Alternatively, the profiles can also be made of stainless steel, galvanized steel, or fiber-reinforced plastic.

[0036] Preferably, the tube profile can have a round, oval, rectangular, or polygonal cross-section. To simplify the design, one embodiment may provide that the first fastening device and the upper fastening device each have the same clamping connectors for connecting the first pendulum rod, the second pendulum rod, and / or the third pendulum rod to the pendulum axis or the horizontal axis of the shelf. The clamping connectors may preferably be made of steel, stainless steel, or a galvanized metal. Alternatively, the clamping connectors may be made of a plastic, preferably a fiber-reinforced plastic. Advantageously, the clamping connectors have two clamping jaws that grip a section of the tube and are clamped by means of a clamping device, e.g., a clamping clamp.They can be clamped against the inserted pipe section using a screw or an eccentric clamp. Advantageously, depending on the strength of the applied clamping force, the held pipe section can be continuously adjusted from slightly sliding to securely fixed.

[0037] For example, cross clamps, angle clamps, or flange clamps can be used as clamping connectors for the pendulum rods and / or the profiles for the horizontal axis of the shelf and / or the pendulum axis. Such clamping connectors are available on the market in various designs. The use of identical profile or tube sections and identical clamping connectors offers the advantage of keeping the manufacturing costs of the pendulum device according to the invention relatively low. Furthermore, it allows for simple assembly and intuitive handling. Another advantage is that the pendulum device according to the invention can be easily expanded, for example, by attaching a separate monitor mount and / or a keyboard mount and / or a leg rest and / or an additional shelf as a further work area, or an armrest.Furthermore, the same profile bars can be used for the cross-connections of the force parallelogram as for the first and second profile bars, or for the first, second, and third profile bars. Using identical profile bars allows for a particularly cost-effective implementation.

[0038] A particular advantage is the almost unlimited ergonomic adjustability of the pendulum mechanism. The pendulum mechanism can be continuously adjusted for a user in the operating position, thus enabling a very comfortable and ergonomic, especially relaxed, posture.

[0039] A particular advantage is the possibility of combining the pendulum device according to the invention with any piece of furniture. It is preferably provided that the pendulum device according to the invention is attached to the furniture via a receiving device and is detachably held on the receiving device by means of the coupling device.

[0040] Preferably, the receiving device may have a horizontally or vertically extending rail that is connected to the furniture, and the rail may have a clamping device, in particular an undercut groove with a T-nut, for receiving the coupling device.

[0041] In order to enable mobile use of the pendulum device or combination furniture according to the invention, it can preferably be provided that the furniture has rollers on its underside, in particular lockable swivel casters, so that the combination furniture can be moved.

[0042] A relaxed, and in particular health- and performance-promoting, sitting / lying posture when using the pendulum device can be achieved, for example, if the furniture has a tabletop or a leg rest, especially a padded leg rest, beneath the shelf. This allows for a relaxed sitting / lying posture when using the pendulum device.

[0043] A particularly advantageous, space-saving design is achieved by running the counterweight rod below the leg rest. This means the counterweight rod, which connects the counterweight to the pendulum, is routed beneath the leg rest or tabletop, making it invisible and unobtrusive to the user.

[0044] One application of the device according to the invention is, for example, the sale of the pendulum device according to the invention as a unit or as a kit. It is also possible to offer and sell the pendulum device according to the invention together with a piece of furniture as a combination piece of furniture. Advantageously, the pendulum device according to the invention can also be combined with existing furniture as a unit. A user can therefore attach the pendulum device according to the invention to existing furniture in their home and upgrade it to an ergonomic workstation.

[0053] Front view. The figures show different embodiments of the solution according to the invention. These are not to be understood as limiting. In the figures, components that function identically are provided with the same reference symbols. It is clear to those skilled in the art that they can modify and combine the embodiments shown in the figures within the scope of protection defined by the claims without departing from the inventive concept.

[0054] Figure 1 shows a schematic 3D view of the pendulum device 1 according to the invention. The pendulum device 1 comprises a pendulum 2, by means of which a shelf 3 can be pivoted about a pendulum axis 24 in order to enable a desired, ergonomically advantageous working position.

[0055] The pendulum axle 24 is detachably connected to a receiving device 11 by means of a coupling device 12. The receiving device 11 can be connected to a piece of furniture to firmly anchor the pendulum device 1 to the furniture. Examples of furniture that can serve as furniture include a rolling container 5, an armchair, a chair, a table, a cabinet, a column, a wall, a rack, or similar items.

[0056] Shelf 3 is designed as a flat work surface and can be used, for example, as a writing surface or a reading surface. It is also possible to place a tablet computer or a book on Shelf 3. Shelf 3 has a horizontal axis 31 around which it can be swiveled to adjust the inclination of the shelf or the shelf surface.

[0057] To prevent objects placed on the shelf 3 from unintentionally sliding off, the shelf 3 can have a fall protection device. This fall protection device can include a raised edge, a raised rim, and / or a non-slip surface, for example, in the form of a non-slip mat. The pendulum 2 has a first pendulum rod 21 and a second pendulum rod 22. The pendulum rods 21 and 22 are connected to each other via the pendulum axis 24 and the horizontal axis 31 by means of a first fastening device 13 and an upper fastening device 14 to form a force parallelogram. The force parallelogram provides torsion-resistant support for the shelf 3, or rather its horizontal axis 31, relative to the pendulum axis 24. At its lower end, the pendulum 2 has a compensating rod 4, at the end of which a counterweight 42 is slidably arranged by means of a lower fastening device 15.To adjust the restoring force of the pendulum 2, the counterweight 42 can be moved along the pendulum rod 4. To do this, the lower fastening device 15 is loosened, the counterweight 42 is moved to the desired position, and then secured using the lower fastening device 15. Moving the counterweight 42 upwards, i.e., towards the pendulum axis 24, shortens the effective lever arm and thus reduces the restoring force, and vice versa. By moving the counterweight 42 along the pendulum rod 4, the pendulum 2 can be easily adapted to different requirements and users.

[0058] Alternatively, the restoring force of the pendulum 2 can be adjusted by replacing the counterweight. The counterweight 42 can be removed and replaced with smaller or larger weights, depending on the length of the balancing rod 4 or on the weight to be placed on the shelf 3. In this embodiment, the first pendulum rod 21 is formed integrally with the balancing rod 4, i.e., the pendulum rod 21 is made of the same profile as the balancing rod 4, i.e., as a continuous rod.

[0059] For universal applicability, the pendulum device 1 can be extended to include a tablet 32, which can be attached to the pendulum axis 24 and provides an additional storage surface. The tablet 32 ​​is connected to the pendulum axis 24 via the mounting device 16. Alternatively, the tablet 32 ​​can also be adjusted and attached directly to the mounting device 11.

[0060] Figure 2 shows a combination piece of furniture 6 according to the invention. The combination piece of furniture 6 comprises a rolling container 5 as the furniture component and a pendulum device 1 according to the invention. The pendulum device 1 is connected to the furniture 5 by means of the receiving device. The pendulum device 1 can be subsequently attached to an existing piece of furniture, for example a rolling container 5, or it can be delivered together with the rolling container 5 as a combination piece of furniture 6.

[0061] Advantageously, the rolling container 5 has steerable casters on its underside to allow the combination furniture 6 to be moved to any location.

[0062] Preferably, the swivel casters are also designed to be lockable, so that after positioning the combination furniture 6 in the desired location, a fixable workstation can be formed by locking the casters.

[0063] Figure 3 shows another embodiment of the combination furniture 6. In this embodiment, the pendulum device 1 has a pendulum 2 with three pendulum rods 21, 22, and 23. As can be seen in Figure 4, the three pendulum rods 21, 22, and 23 are arranged at a distance from each other in the form of a triangle. This results in a particularly rigid support for the shelf 3. Advantageously, this type of support can also effectively compensate for laterally acting moments.

[0064] In the embodiment shown in Figures 3 and 4, the top of the rolling container 5 is designed as a leg rest 51. The leg rest 51 can be designed as a padded leg rest 51 and allows a user to comfortably rest their legs on it. This allows an individually adjustable reclining / sitting position to be set via the pendulum device 1 according to the invention. Figure 5 shows another embodiment of the combination furniture 6 with the pendulum device 1 according to the invention. Here, too, the combination furniture 6 has a rolling container 5 to which the pendulum device 1 according to the invention is attached. The pendulum 2 in this embodiment has two pendulum rods 21 and 22. In contrast to the previously shown embodiments, the compensating rod is now not formed integrally with the pendulum rod 21, but is offset laterally.The pendulum rod 21 and the pendulum rod 22 are connected to the compensating rod 4 via a compensating axis 41, which runs coaxially to the pendulum axis 24. The roll container 5 is arranged between the compensating rod 4 and the first pendulum rod 21. The compensating rod 41 is advantageously guided inside the roll container 5 and is therefore not visible from the outside.

[0065] The embodiment shown in Figure 5 makes it possible to provide an ergonomic workstation via the shelf 3 even in confined spaces. For example, the mobile pedestal 5 can be used as an auxiliary piece of furniture for hospital beds or armchairs and positioned next to a hospital bed or armchair so that the workstation on the shelf 3 can be positioned ergonomically advantageously above the armchair or hospital bed.

[0066] By means of the lateral offset of the compensating rod 4 with the compensating weight 42, it is possible to bring the combination furniture 6 according to the invention as close as possible to a hospital bed or to an armchair without the compensating weight 42 colliding with the hospital bed or the armchair.

[0067] The pendulum device 1 or combination furniture 6 according to the invention is universally adaptable and therefore suitable for a wide variety of applications. The simple design of the pendulum device 1 according to the invention, in particular the use of prefabricated, cuttable profile rods for the pendulum rods 21, 22, and 23 and / or the pendulum axis 24 or the horizontal axis 31, as well as the compensating rod 4 and the compensating rod 41, enables a structurally advantageous design. Conventional clamping connectors can be used to connect the profile rods to each other or to the shelf 3 or the tray 32. Cross connectors, angle connectors, or flange clamping connectors can be used for this purpose. This makes it possible to achieve a cost-effective implementation of the pendulum device 1 or the combination furniture 6 according to the invention.
