This claims priority to Mexico patent application No. MX/a/2021/005264 filed May 4, 2021. The content of this application is incorporated herein by reference in their entirety.
There are different types of swings, cribs, beds, furniture and other elements that move based on oscillatory movement from one or more pendulums or suspension points; the foregoing with vastly different purposes in different industries, among them, to enjoy an experience either recreational, relaxing, or simply pleasant for the user.
Pendulum movement requires a fixed point to suspend a mass by means of a rope or arm. Devices that provide the user with the experience of a pendulum movement require a structure that is invariably external to the tilting mass or object. On the other hand, any object that floats in a fluid is susceptible to oscillatory movements. Said devices that use this principle to provide the user with the experience of an oscillating movement, require a tank with a size sufficiently larger than the floating object.
These known ways to enjoy the oscillating movement require wide spaces, large structures, in some cases heavy, as well as large amounts of fluids and even additional systems to improve comfort.
Disadvantages of the prior art are solved with the system object of this invention, which allows the user to enjoy the sensation of an oscillating movement anywhere, the main advantage of the present invention being to reduce the size of the structures, achieve a versatile device, not requiring special facilities or to have permanent spaces.
Likewise, the present invention solves the problem of being able to count on greater stability by restricting the pendulums inside the posts, limiting the amplitude of the oscillation of the mass and thus its displacements and trajectories, making the system much more stable and safer.
As mentioned above, observing the need to take advantage of that movement or trajectory and so that in any object or piece of furniture you can enjoy precisely that oscillatory movement without the need for so much space, robust or external elements, and with stability, a system that allows to deliver the oscillatory movement outside the geometry of the structure that contains the pendulum is proposed, in this particular case, above said structure.
The inventive system proposed has been conceived to fully solve this problem based on two structures jointed therein, a static one with a plurality of fastening points (four) to anchor a plurality of ropes (four) to the plurality of pendulums (four); the other that rigidly couples the masses of the plurality of pendulums (four) and transforms them into a single, oscillating mass. Likewise, it also has a plurality of vertical arms (four) that replicate the oscillatory movement of the plurality of pendulums (four) in the upper part of the geometry of the system in a homogeneous and controlled manner. This is possible, since the solution proposes to deliver the oscillatory movement of the pendulum in the upper part of its geometry and recover it with any object that is placed on it.
Among other uses, it offers the user an experience similar to that of floating in a fluid, with the advantage of not having to submerge in it or come into contact with substances to which a user may be sensitive. Similarly, there is no need to temporarily confine a user to a tank that can alter the user's emotional state.
The invention refers to a system of a plurality of pendulums with controlled oscillation and trajectory with two structures of similar design (a quadrangular frame (4) with vertical posts or arms attached to the corners of the frame). A first static structure (1) having a rectangular tube profile (RTP) and a second non static structure (2) having a solid circular section profile (Round Bar) placed inside of the first static structure (1). Both are jointed therein through four ropes (3) each of said ropes with equal length, which connect, one by one, each of the four suspension points (24) with the four fastening points (16). The four suspension points (24) are located in the upper part of each one of the four posts (17) of the first static structure (1), while the four fastening points (16) are located in each one of the four nodes (15) of the second non static structure (2). The first static structure (1) is fixed resting on its frame (4), horizontally, on any flat surface, for example, the floor. The second non static structure (2) is suspended within the first static structure (1), free to move transversally and longitudinally. The four ropes (3) operate as pendulums with independent suspension points (24) and independent fastening points (16) and coupled by the frame (9) of the second non static structure (2), giving said second non static structure (2), a swinging movement which is a product of the action of the forces relating to the gravity and tension of the four ropes (3). The upper end of each one of the four arms (14), of the second non static structure (2), replicates the swinging movement of its end attached to each one of the four nodes (13), in equal magnitude, but in an opposite direction.
The first static structure (1) having a quadrangular frame (4) with a rectangular tube profile (RTP), in which its upper horizontal surface (5) must have, in each one of the four corners of the frame (4), a hole (8) of the same section and dimension as the RTP used for each one of the four posts (17); each hole (8) will allow to connect the inside of the frame (4) with the inside of each one of the four posts (17). On the horizontal lower surface (6) of said first static structure (1), the whole face (7) of the frame (4) must be retired, thus allowing the free transit of the second non static structure (2), at the moment of assembly. The four posts (17) of the first static structure (1) must have perforations (18) on both sides (19) of the RTP with a common edge (20), one perforation per side (19) located as close as possible to the end of each one of the four posts (21) and the common edge (20). The diameter of the perforations (18) is in function of the diameter of the bolts (22) that will be accommodated. The end without perforations (23) of each one of the four posts (17) is attached to the frame (4) above each hole (8) on the frame (4), making sure that each one of the four posts (17) is perpendicular to the frame's surface (10). The bolts (22) must have the mechanical properties required and sufficient to resist, without any deformation, the weight of the second non static structure (2) plus the weight of the object placed above said second non static structure.
The second non static structure (2) having a solid circular section profile (Round Bar) also form a quadrangular frame (9) with four arms (12), with each one of said four arms located in each corner, perpendicular to the frame's surface (10). The length of each one of the four arms (12) shall be longer than that of each one of the four posts (17), long enough to tower over each one of said four posts (17) when the system is assembled, thus avoiding that the object placed above the arms (12) of the second non static structure (2) gets in contact with any of the four posts (17) of the first static structure (1). The material of each one of the four ropes (3) must have all the mechanical properties required and sufficient to resist the friction and tensile, flection, torsion and cutting efforts produced by the tension and movements of the system in operation. Each one of the four ropes (3) shall have a closed ring shape.
In order to assemble the system, the second non static structure (2) is placed in a position that allows the frame (9) to be placed below and with the arms (12) pointing upwards, stringing the four ropes (3), one in each one of the four arms (12) of the second non static structure (2). Then, the second non static structure (2) is introduced in the first static structure (1) and upon completion of this assembly, each one of the four ropes (3) is pulled in a radial direction, embracing the base of each one of the four arms (13) and is also rotated, changing the direction of the starting pull, thereby surrounding the section of the elements (11) of the frame (9), continuing with the pull in a vertical direction and through the inside of each one of the four posts (17) of the first static structure (1), leading each one of the four ropes (3) to each one of the four suspension points (24), aligning the end of each one of the four ropes with the axis of each one of the perforations (18) and placing a bolt (22), with each one of the four ropes (3) mounted on the bolt (22) and the bolt being supported on the sides (19) of each one of the four posts (17). Upon completion of the process above, the assembled system is rested on the surface on which said system will be used.
For illustrative and non-limiting purposes, the RTP (Rectangular Tube Profile) and Round Bar (Solid circular section profile) have been chosen as the preferred embodiment of the system, due to their mechanical characteristics of resistance, however, the system may be embodied using several other materials (wood, MDF, acrylic, aluminum, etc.), as long as the required structural stability is preserved for its functioning. The choice of materials may change the embodiment methods, but not the essence of the system itself, which is the combination of an internal swinging structure and a fixed support and contention structure, which transfers its oscillation to an external object mounted on said structure.
In order to complement the description and with the purpose of providing a better understanding of the characteristics of the invention, the present description is accompanied by drawings, as an integral part of the same, for illustrative and non-limiting purposes, representing the following:
