Electric damper for hinged doors by a dynamo mounted on the door leaf and a small rubber mounted on its ratchet ring and an arched rail mounted on the frame.

Abstract

This device is used for the soft closing of all types of hinged doors. Currently, hydraulic jacks have been responsible for this task, but they have had disadvantages that I intended to overcome by designing my device. Some of these disadvantages include the resistance force of the device when the door leaf is opened, the inability to use it in high-traffic areas, high depreciation, and the complexity of installation and repairs. I completed my device by using a dynamo connected to the rubber by a ratchet ring and installing it on the door leaf, as well as using an arched rail on the upper part of the door frame, in cases where the opening and closing range of the door leaf has a longitudinal and transverse slope, and by using an electronic eye and microswitch. In cases where the opening and closing area of ​​the door leaf does not have a longitudinal or transverse slope, the arch rail can be removed and the ground surface can be used instead, and the dynamo is transferred from the upper part of the door leaf to the lower part of the door leaf. The ratchet ring is loose in one direction and locked in the other direction, transferring the dynamo force to the ground or arch rail and closing the door leaf (like the sun on the rear wheel of a bicycle). In this device, the dynamo provides the necessary force for closing, and this action is performed by the dynamo's rubber contacting the ground or the arched rail. Since the dynamo's rotational speed is always constant, we no longer need a hydraulic assistance system.

Description

Description of the invention Title of the invention (as stated in the declaration) Electric damper for hinged doors using a dynamo mounted on the door leaf, a small rubber mounted on its ratchet ring, and an arched rail mounted on the frame. Technical background of the relevant invention This invention relates to types of hinged doors that can automatically close doors opened by people after a certain period of time and at a desired speed. Technical problem and stating the objectives of the invention One of the major technical problems of current devices is the spring used in it. This spring resists when the door is opened, and on the other hand, after releasing the door, the door immediately starts moving to close. This creates a problem when several people intend to pass through the door one after the other. Either one person must hold the door until all people pass through, or each person must individually prevent the door from closing and pass through. A description of the state of the prior art and the history of developments related to the claimed invention. By searching for Electric restraint on the introduced sites, I did not see any device. By searching for Hydraulic restraint, I saw the same current restraints that work with a spring and an oil shock absorber, which works completely differently from my device. The spring of this device takes the energy of closing the door from the pedestrians when it opens and stores it in itself. The hydraulic system also adjusts the speed of closing the door. This hydraulic system, like a car shock absorber, only works when the door is closed and has no resistance when it is opened. Providing a solution to an existing technical problem along with an accurate, sufficient, and integrated description of the invention At the beginning, I will name the various components of my inventive device and briefly explain it. 1) Dynamo and gearbox assembly: This dynamo gearbox (5) is small in size. The installation location of this dynamo and gearbox is on the door leaf (3) from the inside and at the bottom or top, depending on whether the opening and closing range of the door leaf has a transverse or longitudinal slope (if it is not sloped, we remove the arched rail (4) and install the dynamo (5) at the bottom of the door leaf (3), and if it is sloped, the dynamo is installed at the top of the door and under the arched rail). It is installed in such a way that the small rubber (7) connected to the output of the dynamo gearbox (5) is in contact with the ground or arched rail (4) and this contact creates friction to the extent that it allows the transfer of power from the dynamo to the ground or arched rail. 2) Arched rail: At the beginning, it is important to mention that this part is used when the ground surface of the inner part of the door, where the door opens and closes, has a transverse and longitudinal slope. In this case, we use this arched rail (4) in the upper part and transfer the rubberized gearbox dynamo from the lower part to the upper part of the door, and the arched rail plays the role of a flat ground for us. In other words, the general case is for cases where the ground of the opening and closing area of ​​the door leaf has a slope, that we prepare the arched rail (4) and install it in the upper part of the door frame (1) and install the gearbox dynamo (5) in the upper part of the door leaf (3). In cases where the door leaf area has a flat surface and no slope, we consider a special and special case and remove the arched rail (4) and transfer the rubberized gearbox dynamo to the lower part of the door leaf.We install the arched rail on the upper part of the frame in such a way that the center of the arch of this rail coincides with the axis of the hinge of the door leaf (2), which is how the dynamo rubber and the arched rail are always in contact with each other because the path of both circles is to the center of the hinge (2) of the door and the radius is equal. 3) Tire with a ratchet ring: This tire (7) is connected to the dynamo output shaft from the ring (6). This ring has a ratchet feature in that it is released in one direction and locked in the other. Like the rear sun of a bicycle that is released in one direction and locked in the opposite direction. This ratchet ring (6) is installed in such a way that its release direction is in the direction of opening the door, that is, when the door is opened, the tire rotates freely without the dynamo shaft moving. On the other hand, when the door is closed and the dynamo is turned on, the ratchet is locked and both the dynamo shaft and the tire rotate and the dynamo power is transferred to the ground or the arched rail. Now that I have described the components of my device, I will explain how to resolve the technical problem. 1) Door resistance when opening: By eliminating the spring and using a dynamo to provide energy for closing the door leaf, and by using a ratchet ring that rotates freely and separately from the dynamo when the door leaf is opened, we eliminate any physical resistance when the door is opened and solve this problem. 2) Immediate closing of the door immediately after the door leaf opens and momentarily preventing pedestrians from passing in crowded places: This defect is easily overcome by using an electronic eye and an adjustable electric timer. As long as a pedestrian is within the door area, the electronic eye does not give the closing command to the dynamo. As soon as the person leaves the open area and the door leaf closes, the electronic eye sends the closing command to the timer. After the programmed time has passed, the timer turns on the dynamo power and the door starts closing. As soon as the door is completely closed and the relevant microswitch is activated, the dynamo power is cut off. On the other hand, if someone approaches the door while it is closing, the electronic eye cuts off the dynamo power and the door remains half-open. After the person passes through the door and the door is fully opened, the closing action is reactivated. Explanation of shapes, maps and diagrams Figure 1 is a general view of the door from the front with the arched rail and dynamo at the top of the door. Figure 2 is the bottom view of the door leaf and alternator with the arch rail removed. Figure 3 is a view of the gearbox alternator and the ratchet and rubber ring installed on the lower part of the door leaf. Figure 4 is a general view of the door from above without the arch rail. Figure 5 is a general view of the door from the outside without the arch rail. A clear and precise statement of the advantages of the claimed invention over prior inventions. 1. As explained, by using a dynamo, a ratchet ring, a rubber, an electronic eye, a timer, and a microswitch, I have made it possible to reduce the force required to open the door to the minimum possible (to the extent of the friction in the door leaf hinges) and also to make the device suitable for high-traffic areas. The price of the device has been significantly reduced and the installation of this device is very simple and easy so that most people can install it. Description of at least one implementation method for implementing the invention The only use of this device is to gently close all types of hinged doors. Explicit mention of the industrial application of the invention By installing this device on single-leaf doors inside the building, whether wooden, metal, aluminum, etc., in various dimensions, as well as double-leaf doors inside and outside the building, pedestrians no longer need to stand and gently close the door after passing through it, because this device does this job. Brief description of the invention This device is used for the soft closing of all types of hinged doors. Currently, hydraulic jacks have been responsible for this task, but they have disadvantages that I intended to overcome by designing my device. Some of these disadvantages include the resistance force of the device when the door leaf is opened, the inability to use it in high-traffic areas, high depreciation, and the complexity of installation and repairs. I completed my device by using a dynamo connected to the rubber by a ratchet ring and installing it on the door leaf, as well as using an arched rail in the upper part of the door frame, in cases where the opening and closing area of ​​the door leaf has a longitudinal and transverse slope, and an electronic eye and microswitch. In cases where the opening and closing area of ​​the door leaf does not have a longitudinal and transverse slope, the arched rail can be removed and the ground surface can be used instead, and therefore we transfer the dynamo from the upper part of the door leaf to the lower part of the door leaf.The ratchet ring is loose in one direction and locked in the other direction, transferring the dynamo force to the ground or arched rail and closing the door leaf (like the sun on the rear wheel of a bicycle). In this device, the dynamo provides the force required for closing, and this action is done by the dynamo's rubber contacting the ground or arched rail, and since the rotational speed of the dynamo is always constant, there is no need for a hydraulic assist system.
