RO134575A2 - Double articulated closing system - Google Patents

Abstract

The invention relates to a double articulated closing system the activation of which is performed, irrespective of its total mass, by applying a minimum force in a direction which changes its operating state, e.g. from "closed" to "open" or vice versa, by moving the load centre of the whole device. According to the invention, the closing device comprises one or several closing elements, such as gates, caps, arms, doors, wings, blades, rods, which open or close by partially pivoting about a rotary shaft which is, in its turn, movable about a point of attachment to the reference system, where the device change from an operating state to the other, such as from "closed" to "open", is achieved by pushing the whole device from a stable equilibrium point to another stable equilibrium point, on a trajectory on which there is an unstable equilibrium point, where, just after overcoming the unstable equilibrium point, the system falls by its own into the aimed stable equilibrium position, with no energy consumption.

DOUBLE ARTICULATED LOCKING SYSTEM

DESCRIPTION

The invention relates to a locking device used in objects with functionality dependent on the approach, removal or pivoting between them of some component parts.

STATE OF THE ART

Objects such as folding hanger, shutter, vertical blind, dam, sluice gate, valve or other types of hydrotechnical constructions, access doors and so on, which are composed of mechanical elements that close or fold, such as gates, lids, arms, doors, wings, slats, rods, etc.

These mechanical elements are connected to the systems to which they belong by hinged joints or other types of pivoting devices which do not use the mass, center of gravity or variation of the contextual forces characteristic of the mechanical elements, in order to facilitate their closing and opening. .

Moreover, the non-use of these forces and variations of forces present in the system leads to the need to counteract their effects, which not only does not make energy consumption more efficient during operation, but complicates the systems by introducing levers, joints, fuses, locking systems and other additional mechanisms that ultimately lead to increased production costs and decreased life of components and even the system itself.

Moreover, it is generally known the need to develop products as simple as possible, with a minimum number of moving components, which as much as possible to use the presence of forces already existing in the system during operation.

This continuing need stems from needs such as increased efficiency in the production and operation of systems, safe operability and maximum predictability, device reliability, minimization of production, operation and maintenance costs, and the lowest possible energy consumption during production and operation. .

The prior art comprises patents such as EP3095358A1, US5687888A, WO2018230944A1, US5690257A, in the field of folding hangers, GB792587 (U), US20130022402 (A1), MX2016010362 (A), US2699652 (A), SG, ), TWM468563 (U) in the field of vertical blinds. These patents disclose objects that have mechanical elements that close or fold, such as gates, lids, arms, wings, doors, slats, rods, etc.

In the field of folding hangers, patents such as EP3095358A1 or US5687888A are known, which refer to folding hangers around a vertical axis, provided with various locking systems in the "open" position, located in the vicinity of the central vertical hinge.

The disadvantage of these solutions is that a hanger according to one of the above patents is operable through a relatively difficult or awkward sequence of several actions, some simultaneous, disregarding the forces in the system that through better design would could have replaced a significant part of these actions. »

Also in the field of folding hangers, patents such as WO2018230944A1 or US5690257A are known, which refer to folding hangers around a horizontal axis, provided with various locking systems in the "open" position, located in the vicinity of the central horizontal hinge.

The disadvantages of such solutions are on the one hand in the sphere of production efficiency and product reliability, on the other hand in the sphere of utility and ease of use.

The fact that a hanger according to US5690257Ase opposes the gravitational force through a locking device exposes the hanger to the major risk of deteriorating rapidly due to the fragility of the locking device, instead of using for locking a force present in the system, such as the hanger's own weight or of the clothes stored on it.

The hanger according to WO2018230944A1 uses two springs for the relative locking in the "open" position, which in addition to the risk of accidental closure due to storing too heavy a garment, has the disadvantage of a very complicated construction, so implicitly a high production cost and a short product life, given the 15 moving components of the assembly.

In the field of hydrotechnical constructions, patents are known such as GB792587 (U), US20130022402 (A1), US2699652 (A), MX2016010362 (A), SG65874 (A1), representing dam or water flow control systems, used for protection against floods.

Gate systems of varying degrees of complexity, such as US20130022402 (A1) or GB792587 (U), use complex devices such as hydraulic pumps, electric or spark-ignition motors for activation and require human or computer control.

The disadvantage of these systems is that they cannot operate independently. They, by their design, ignore the fact that the variation of the contextually existing forces in the system, such as the increase of the water level or flow, could command and implement the activation of the dam system naturally, which would make that system deployable and in areas without infrastructure and at the same time be operational in emergency conditions such as a power failure or a faulty central control system.

Patents such as MX2016010362 (A), US2699652 (A) or SG65874 (A1) are also known, representing dam or water flow control systems that can operate autonomously, in direct accordance with the change of the water level in a certain area. They have the disadvantage that after their location on a watercourse, that course is no longer navigable, the protection of a populated area against floods by using these systems can lead to commercial or transport disadvantages.

In the field of vertical blinds, patents such as GB2509209 (A) or TWM468563 (U) are known as mechanisms for folding, transporting on a rail or twisting the slats of a vertical blind. The disadvantage of these solutions is the very complicated construction, so implicitly the high production cost and the low lifespan of the components, given the degree of miniaturization, as well as the large number of moving components of the systems.

The hanger is in unstable equilibrium when its center of gravity and the point of attachment to the reference system are superimposed, as illustrated in Figs. 6.b.

pushing or twisting the hanger vertically forward A removes the center of gravity of the device horizontally from its point of attachment to the reference system forward A, so that the hanger according to the invention tends to fall into the open position shown in Fig. . 6.a, as this represents the stable equilibrium point close to the direction in which the center of gravity is directed in relation to the point of attachment to the reference system.

pushing or twisting the hanger vertically backwards B horizontally removes the center of gravity of the point or gripping device from the reference system backwards B, so that the hanger according to the invention tends to fall into the folded position illustrated in Fig. . 6.e, rapidly passing through intermediate instantaneous positions illustrated in Figs. 6.c and FIG. 6.d, as this is the stable equilibrium point close to the direction of the center of gravity relative to the point of attachment to the reference system.

The arms 103 and 104 of the hanger incorporate the elements 105 and 106 respectively of a rotating joint such as a hinge, through which the clamping hook 101 continues with the portion 102 which acts as a rotary axis, which after passing through the hinge bushes is fixed below with a fuse 107 which may be, for example, in the shape of a rivet, a grover-type washer around a groove dug all around in the shaft, or a nut around a threaded end of the shaft.

The inner faces of the arms 103 and 104, which come into contact when the hanger is in the open position, form with the front and rear faces of the arms of which they are part, respectively, an angle which allows them to be in the open position of the hanger. supports each other so that both the weight of the hanger and the weight of the clothes placed on the hanger prevent the fall of 2019 00289

15/05/2019 accidental hanger in the folded position that would facilitate the unwanted fall of the coat on the hanger.

when the hanger in the "open" position as illustrated in Figs. 6.a anatomically stores a garment, for example fastened on a horizontal bar inside a wardrobe, it is sufficient to fasten the garment to the shoulder more accessible to the user and to make a twisting movement towards the back of the hanger B, so that the hanger falls into position " folded ”illustrated in Figs. 6.e, instantly releasing the coat and remaining hanging in the "folded" position on the horizontal bar of the closet.

The problem solved by the invention is a simple and inexpensive product hanger, which makes it possible to put and take the clothes in and out of the anatomical position of storage with one hand, with a significantly lower effort and significantly higher speed than any solution from prior art, without the need to remove the hanger from the closet to remove the stored clothing from the hanger.

The foldability of the hanger according to the invention also brings the advantage of a much smaller volume occupied when it does not perform the function of holding a garment.

Thus, in the embodiment of the present document, it has been preferred to lock the central shaft 102 of the hanger with a grover washer, nut or other removable device 107 so that the hanger is easy to disassemble and reassemble.

Figures 13.a, 13.b and 13.c represent successive transient stages on the trajectory of the stroke on which the folding shutter according to the invention with blades coupled two at each vertical axis of rotation, traverses it between the “closed” position - Fig. 13.a and “open” - Fig. 13.c, from a semi-lateral front perspective.

Figure 13.d is an overview from a semi-lateral front perspective of the folding shutter according to the invention with slats coupled two at each vertical axis of rotation, when the slats 301 and 311 were close together and slid sideways on the rail 307 which contains the upper clamping systems 303 of each pair of slats and at the same time on the common rod 305 from which all the pairs of slats are clamped at their lower extremities. 1

The notation of the elements in the figures was done with Arabic numerals and letters from the Latin alphabet, as follows: A - the area considered to be in front of the shutter, B - the area considered to be behind the shutter, 201 - rotating lamella, 202 - longitudinal axis of rotation of the rotating lamella 201,203 - point of attachment of the axis of rotation 202 in the upper rail for tightening the lamellae 207, 204 - point of attachment of the axis of rotation 202 in the lower common rod for orienting the lamellae, 205 - dowel rod 2019 00289

The gravitally adjustable shutter is an embodiment of the invention, in the sense that the slats represent the closing elements of the system, which open or close by partial pivoting around their own longitudinal axis of rotation, which in turn, by means of the clamp 204 in the movable rod 205 of the lamella, it is movable around a point of attachment to the reference system 203, so that the operating stages "closed", "open" or various degrees of intermediate opening of the shutter are obtained by orienting the lamellae in various directions under its own weight, varying the direction and distance between the two points of attachment of each blade to the system to which they belong.

The shutter is in unstable equilibrium when the center of gravity of the blades 201 and their points of attachment to the reference system 203 are superimposed, as illustrated in Figs. 12.b.

pushing the lower common rod 205 towards the rear B of the shutter horizontally removes the center of gravity of each blade 201 from its point of attachment in the reference system 203 towards the rear B, so that the shutter according to the invention tends to fall without energy consumption in the open position illustrated in FIG. 11 and FIG. 12.c, as this represents the stable equilibrium point close to the direction of the center of gravity of each slide 201 relative to the point of attachment of the reference system 203.

Pulling the lower common rod 205 towards the front of the shutter horizontally removes the center of gravity of each blade 201 from its point of attachment in the reference system 203 towards the front A, so that the shutter according to the invention tends to fall in the closed position illustrated in FIG. 10 and FIG. 12.a, as this is the stable equilibrium point close to the direction in which the center of gravity of each slide 201 is directed in relation to the point of attachment to the reference system 203.

in FIG. 13.a, 13.b, 13.c and 13.d illustrate a variation of the shutter according to the invention, in which instead of a rotating blade, a pair of blades was chosen, the operating principle remaining identical.

The pairs of blades 301 and 311 are constructed symmetrically, incorporating on the common vertical edge 302 the elements of a rotating joint such as a hinge, through which the hook 303 in the upper rail 307 continues with a rotating shaft, which after passing through the hinge bushes it is connected below it to the lower common rod 305 by means of the clamp 304.

Following the implementation of the disclosed inventive concept, each of the two blades 301 and 311 can be rotated horizontally around its own common vertical axis 302 so as to stick to each other perpendicular to the window or to open in a plane approximately parallel to the window, depending on the movement of the center of gravity. The center of gravity is moved by the vertical rotation of the common axis of rotation 302 about the point of attachment 303 of the reference system.

For the operation of the shutter according to the inventive concept disclosed in this document, it would be sufficient for the upper fasteners 203 or 303 of the slats 201 or the pairs of slats 301 and 311 to be made at equal distances, directly in the upper window sill or in the ceiling of the room where it is installed the shutter. However, for functional reasons, respectively so that the area of the window or opening covered by the shutter according to the invention can be completely cleared as illustrated in Figs. 12.d and Fig. Respectively. 13.d, the upper clamping rails 207 and 307 were chosen, provided with semi-locking steps predefined at a distance equal to the widths of the slats 201 or the pairs of slats 301 and 311. / / / ¹⁵ C / lu

The shutter according to the invention also makes it possible to close and open it almost instantly, regardless of the area of the window or opening it covers, using the weight of the slats itself.

Depending on the materials of which the slats and all other components are made on the one hand and its location relative to the window or the opening it covers on the other hand, the shutter according to the invention can function both inside and the vertical blind control of light rays, as well as outside as a blind or curtain-type installation, protection against various meteorological phenomena such as storms, rain, blizzards, as well as anti-burglary systems.

if the slats are made of relatively light materials and the forces that can occur in the environment, such as strong winds, could cause uncontrolled movement of the shutter, you can opt for additional mechanical elements on a case-by-case basis. in the vicinity of the slats, for guiding or locking them in the desired position, such as stops, guide spurs, latches, etc.

The shape of the wings 403 and 404 is designed so that in the case of a normal water level, the gate is in the "closed" position as illustrated in Fig. 14 and maintain a relatively hydrodynamic shape, with the wings 403 and 404 approximately glued together, not preventing the normal flow of water.

To increase water resistance, the wings 403 and 404 have a circular cross-section. The upper area of each wing has a longer length than the lower area, which together with the shape of a circular arc, generates a flared shape in the upper extremities, which gradually decreases the hydrodynamic coefficient of the entire portion increasing sensitivity to water forces as the level water rises.

When a significant volume of water comes forcefully from downstream B and there is a risk of flooding areas outside the normal watercourse upstream A, this volume of water pushes upstream the flared area of wings 403 and 404 hitherto above the water, forcing the central shaft 402 to rotate in its clamping system 401 upstream A, moving the center of gravity of the gate upstream A from the clamping point in the reference system 401.

This leads to the natural tendency of both wings to fall in the closed position ”, with the ends of the wings 403 and 404 supported on the banks and the axis of rotation 402 inclined upstream A.

The higher the force of the water from downstream B to upstream A, the stronger the gate will be pushed into the "closed" position. ₇

For situations where the aquatic currents are not stable in terms of direction, the central axis 402 of the gate may be provided with a longitudinal stop 406, which in addition to the hydrodynamic role, has the function of not allowing any of the wings 403 and 404 to closes over the other wing, in the presence of lateral forces in the system that would prevent the gate from closing in the appropriate direction.

For a high degree of responsiveness of the gate according to the invention, lever systems with counterweights can be attached to adjust the balance sensitivity, or simple hydraulic systems such as propellers, hydraulic ramps, etc. can be built. at greater distances downstream B from the gate, which can be activated and the dam gate can act against remote flooding through cable systems, pulleys, etc. before a massive excess water flow endangers the areas to be protected.

Depending on the geographical context and needs, various variations of the gate according to the invention may be located at the mouth of rivers or other watercourses in rivers, lakes, seas or oceans, characterized by the ability to flood meadows, deltas, estuaries or other forms of relief near the mouths. Also, for regulating the flow or force of aquatic currents, gates according to the invention can be installed along rivers as dams or mobile valves, or even in coastal areas.

The problem solved by the invention is the realization of a gate for flood protection or liquid flow control that acts independently, quickly, completely mechanically and self-powered, without the need for a human or computerized control center, bearing capable of protecting an area against floods in extreme situations such as power outages, destroyed control systems or non-existent infrastructure, diminishing the impact of water flow from downstream B to upstream A, by redirecting aquatic forces to the bottom of the water and to the banks.

At the same time, the utility of the gate according to the invention is all the greater as it works completely ecologically and offers the possibility to be designed in a form that does not impede the navigability of the watercourse where it is built.

IV - ACCESS GATE ACCORDING TO THE INVENTION

The fourth embodiment relates to an access gate composed of a mounting bracket 503 rotating vertically relative to the gate, a mounting bracket connected to one or more wings or access doors 501 through one or more several joints with a vertical axis of rotation 502 relative to the gate, making it possible to open and close the gate quickly and with minimal energy consumption by moving its center of gravity, which determines the tendency of the gate to fall into one of the open or closed positions , positions that coincide approximately with the strokes of the stroke of the rotating support holder 503 in the vertical plane of the gate.

The access gate is an embodiment of the invention, in the sense that a wing 501 represents the closing element of the system, a wing that opens or closes by partial pivoting around the axis of rotation 502 of the joint in the area of the column of the gate 505, axis of rotation which in turn, by means of the rotating device 503, is movable around a point of attachment to the reference system.

15/05/2019 zo rotation 502 around the clamping point 503 to the trajectory necessary and sufficient for the proper operation of the system, 505 - the gate pillar, which supports in operation the double articulated system underlying the operation of the access gate according to the invention. J

The wings of the access gates in the prior art are generally very heavy, closing and opening them requires a relatively large human effort or motors>

strong in terms of developed strength.

Space limitations in the case of automated access gates often lead to the decision to install motor gates of relatively small size and power, which leads to a very slow transition of the gate from one operating stage to another, such as from "closed" to "open" or vice versa.

By constructing according to the disclosed inventive concept a pillar 505 which moves or contains a system 504 which allows the vertical rotation of the axis of rotation 502 supporting the wing of the gate 501, around a joint 503 by means of which it is gripped by the reference system, the movement of the wing between the “closed” and “open” positions can be done mainly under the own weight of the wing, the energy consumed necessary to activate the gate being equivalent only to the effort to remove the gate from a stable equilibrium state and its passage over the unstable equilibrium point. in which the axis of rotation 502 of the wing is in a vertical position, the gate having the constructive capacity to continue autonomously the movement of the axis 502 of support and rotation of the wing towards the expected stable equilibrium point, equivalent to the new desired operating stage. 1

In order to minimize the energy consumed for activation, the access gate according to the invention may comprise lever and / or counterweight systems for balancing or adjusting the sensitivity by adjusting the forces that maintain the steady state of the device.

and 2019 00289

15/05/2019 if for the minimization of the consumed energy a point has been reached where the access gate has become activable by forces that appear unforeseen in the system, such as wind breeze, as well as for security reasons, you can choose to place locking systems such as latches or automated yales in the vicinity of the wings.

According to the inventive concept disclosed, the manual or motorized movement of the upper end of the axis of rotation 502 on an arc-shaped trajectory with the center at the rotating point 503 and the radius equal to the height of the axis 502 from the front of the gate A to the area behind the gate B, after exceeding the unstable equilibrium point at which the axis of rotation 502 is in a vertical position, is equivalent to the horizontal removal of the center of gravity of the device from its point of attachment to the rear reference system B, so that the wing of the gate according to the invention tends to fall into the open position illustrated in Figs. 19 and FIG. 22, since it represents the stable equilibrium point close to the direction in which the center of gravity is directed in relation to the point of attachment to the reference system 503.

Similarly, the manual or motorized movement of the upper end of the axis of rotation 502 on an arc-shaped trajectory with the center at the rotating point 503 and the radius equal to the height of the axis 502 from behind the gate B to the area in front of the gate A, after passing the point of unstable equilibrium in which the axis of rotation 502 is in a vertical position, is equivalent to the horizontal removal of the center of gravity of the point device or clamping of the reference system to the front A, so that the wing of the gate according to the invention tends to to fall into the closed position illustrated in Figs. 21 and FIG. 24, since this is the stable equilibrium point close to the direction in which the center of gravity is directed in relation to the point of attachment to the reference system 503.

For the situation in which the gate wings according to the invention are so heavy that their fall in one of the stable equilibrium points can produce shocks that damage in any way the wing itself, the locking system or any other element of the environment, the access gate according of the invention may be

and 2019 00289

fitted with shock absorbers at the ends of the strokes of the joints or locking elements.

The problem solved by the invention is the construction of an access gate which can be operated with a minimum of energy consumed and which passes very quickly from one operating stage to another, such as from "closed" to "open" or vice versa.

At the same time, given the trapezoidal shape of the wing 501, the transition from one stage of operation to another produces a slight rise from the ground of its lower edge, allowing the opening and closing of the gate regardless of the presence of small obstacles on the ground surface, such as be it snow, small stones, spontaneously grown plants or other objects that, in the case of state-of-the-art gates, obstruct the rotary movement of the wings. and f
