Clampable Lid Opening Multi-Handle Mechanism for Double-Lid Cooling Devices

Abstract

The invention presents a lockable lid opening handle mechanism (3) for double-lid chest freezers. The mechanism comprises a right lid handle (1), a left lid handle (2), a locking mechanism (3), release buttons (4, 5), and a locking pin / spring element (6). The handles (1, 2) are normally connected to the locking mechanism (3) and work together to open both lids (7, 8) simultaneously. When one of the release buttons (4 or 5) is pressed, the corresponding handle (1 or 2) detaches from the locking mechanism and opens only the lid to which it is attached (7 or 8) independently. This ensures flexibility of use, ergonomics, and energy efficiency.

Description

1 Specifications Multiple Lockable Lid Openings for Double Lid Cooling Devices Handle Mechanism Technical Area The invention is in the technical field of refrigeration equipment, particularly chest freezers. It relates to mechanical handle mechanisms for lid systems. The invention applies particularly to chest freezers with double doors, in which both sides... enabling the lid to be opened selectively together or independently, It relates to the interlocking double / multiple handle mechanism. State of the Art 15 Today, chest freezers with double doors have door opening mechanisms. It is generally implemented using two basic approaches: (a) independent separate cover for each lid (b) handle systems or (b) a single central handle attached to both covers systems. In the first approach, when the user wants to open both lids at the same time, both The lids must be lifted by grasping the handles individually; this is a commercial requirement. 20 in use, especially in situations where the user wants to perform the operation with one hand. This causes difficulties in use. In the second approach, the central handle is each It is mechanically connected to the two lids, and when lifted, both lids open simultaneously. They open in this way; however, in these systems, the lids open independently. This is not possible, which leads to unnecessary loss of cold air and a 25% reduction in energy efficiency. This leads to a decrease in temperature and disrupts the temperature balance inside the device. In the current technology, the specification numbered EP0903095B1, “Freezer chest for frozen products, This patent is titled "especially for ice creams and deep-frozen food". In this patent, located at the top of a chest freezer body and with a hinge axis of 30 an access opening that can be closed with at least one cover element that can rotate around it 2 It is defined as follows: The lid can rotate around a hinge pin. a mechanism that attaches to the body and creates a force in the closing direction Thanks to this, it has an automatic shut-off feature. However, the aforementioned In this solution, the lid mechanism is primarily designed for single-lid structures. In multi-lid systems, the lids can be opened by the user with a single movement. to be controlled or to provide independent / joint opening options No solution is offered. Therefore, for commercial use, especially large volumes... Chest freezers present limitations in terms of user ergonomics. It is possible to get out. Another solution is found in patent number US10386110B2, titled "Chest freezer". This document describes the covering that covers the top of a chest freezer. The cover structure consists of multiple sliding panels that move on parallel rail profiles. A structure is defined in which a cover element is used. The system has two sides. Multiple cover elements, including a cover and a central cover, rails 15 It can be opened and closed by sliding on it. User manuals are available on the covers. It includes handle elements so that it can be held. However, Since this structure is primarily based on sliding door architecture, it features hinged double doors. lift-to-lid systems used in chest freezers with lids It does not offer a handle or lid opening mechanism solution. 20 Additionally, the lids can be opened ergonomically, either together or independently. No mechanical linkage mechanism providing this is described either. Another solution mentioned in the literature is DE4403336A1, titled "Chest freezer". This is explained in the patent document. This document states that the chest freezer has 25 to make it easier to open the lid, the gap formed between the lid and the body A temperature-dependent valve system that balances the pressure difference is proposed. This reduces the force required to open the lid, and the lid is then closed by the user. This makes it easier to remove. However, the aforementioned The solution is to reduce the force required to open the lid, and the multi-lid chest type 30 in freezers, the lids can be opened with a single handle or 3 for use cases such as being able to open independently when needed It does not contain a mechanical mechanism. Therefore, the covers are operated by the user. the problem of controlling it in a more ergonomic and flexible way is not solved It remains. Common disadvantages of the previous technique are: (i) the lids are both together and (ii) the absence of a practical mechanism that allows it to be opened independently (iii) lack of flexibility in use, and (iv) low operational efficiency. Unnecessary energy waste in some use cases. As a result, in current technical solutions, chest freezers have lids. The systems are either single-door structures or multi-doors that move independently. It focuses on mechanisms that can be opened and closed simultaneously, offering the user both ergonomic handle and mechanical system that provides independently operating lid control A solution offering a linkage mechanism has not been adequately presented. 15 Purpose of the Invention The main purpose of the invention is to improve existing systems in double-door chest freezers. To address the lack of flexibility in use and to provide the user with both covers together 20 the ability to open and the ability to open the lids independently when desired It offers a practical and ergonomic lid opening mechanism that enables easy access. The advantages offered by the invention are as follows: - Flexibility of Use: The user can open both lids together by lifting a single handle. 25 He can open or release only the desired lid by pressing the button. It can be opened independently. - Ergonomic Design: Enables one-handed operation, especially for commercial use. It increases operational efficiency. - Energy Efficiency: Only the lid that needs to be opened, avoiding unnecessary cold. 30 It prevents air loss and reduces energy consumption. 4 - Mechanical Reliability: Thanks to the spring-loaded locking pin and clamping mechanism. The system provides a secure connection during normal use, release It can be easily deactivated by pressing the button. - Automatic Return: The locking mechanism automatically returns when the lid is closed. It locks into place, making it ready for use. 5 Explanation of the Figures The invention is exemplified by the following figures: Figure 1: Isometric view of the handle mechanism that is the subject of the invention, 10 Figure 2: Top view of the handle mechanism, which is the subject of the invention.

It is based on the mechanism. The system consists of a right cover handle (1), a left cover handle 5 the handle (2), the locking mechanism located between these two handles (3), with release buttons (4, 5), locking pin or spring element (6) as required. In these cases, it consists of elements such as the spring element (6). Figure 1 isometric of the invention. its appearance; right lid handle (1), left lid handle (2) and their The combination with the interlocking mechanism (3) is shown. 10 Figure 4 shows the variations in lid opening; (a) both lids (7, 8) opening together, (b) opening only the right cover (7), (c) opening only the left cover (8) Opening scenarios are shown. Right lid handle (1) and left lid The handle (2) is mounted to the respective covers (7, 8) via mechanical fasteners. 15 These handles (1, 2) enable the user to lift the covers (7, 8). They are ergonomic handles. Both handles (1, 2) are ergonomic when in normal use. They are connected to each other through a mechanical interlocking mechanism (3) and It acts as a single unit. The clamping mechanism shown in Figure 1 (3) consists of the right (1) and left (2) handles. It is the mechanism that normally allows them to be mechanically connected to each other. This mechanism (3) activates the two handles (1, when one of the handles (1 or 2) is lifted. 2) to move together and therefore the right flap (7) and the left flap (8) are in sync This makes it possible to open in a timely manner. The locking mechanism (3), 25 spring locking elements, locking pin, latch system or similar mechanical connection It consists of its elements. Figure 5 shows a detailed view of the locking mechanism (3, 6); the locking principle and The interaction of the release buttons (4, 5) is shown. Locking pin / Spring 30 element (6), mechanical lock that provides clamping between handles (1, 2). 6 It is a component. The handles (1, 2) are connected to each other by a spring or ratchet mechanism. It enables connection. The spring element shown in Figure 5 (6) is the locking pin or clamping mechanism (3) is the elastic element that allows it to return to its normal position. Thanks to this, 5 The locking mechanism (3) remains in the locked position under normal conditions, the user When there is no intervention, the handles (1, 2) remain connected to each other. The right release button (4), shown again in Figure 5, and the right handle (1) located on it and when pressed, the locking mechanism (3) is disabled. 10 It is the button that allows the right handle (1) to move independently by releasing it. Similarly, the left release button (5) is located on the left handle (2). located and when pressed, disables the clamping mechanism (3) on the left It is the button that allows the handle (2) to move independently. Figure 4 shows the variations in lid opening; (a) both lids (7, 8) opening together, (b) opening only the right cover (7), (c) opening only the left cover (8) Opening scenarios are shown. The right door (7) is on the right side of the freezer. It is the cover on the side and is opened via the right handle (1). The left cover (8) It is the door on the left side of the freezer and 20 via the left handle (2) It is opening. The system works on the following principle: In the normal use situation shown in Figure 1, the right handle (1) and the left handle (2), mechanically connected to each other via the interlocking mechanism (3) 25 This is the case. This locking is achieved with the help of a locking pin or spring element (6). is provided and the locked position is maintained by the spring element (6). In this case The locking occurs when the user removes either of the handles (1 or 2). Thanks to its mechanism (3), the two handles (1, 2) move together and are connected to it The right cover (7) and the left cover (8) are opened simultaneously. 30 7 When the user wants to open only one of the covers (7 or 8) shown in Figure 4, the relevant release button (4 or 5) located on handle (1 or 2) Pressing this button (4 or 5) temporarily releases the locking mechanism (3). by disabling the relevant handle (1 or 2) from the other handle (2 or 1) This allows it to detach. Thus, when the button (4 or 5) is pressed, the handle (1 or 2) 5 It only moves the cover (7 or 8) to which it is attached, and the relevant cover (7 or 8) While one lid opens independently, the other lid (8 or 7) remains closed. When the cover (7 or 8) shown in Figure 4 is closed, the locking mechanism (3) Thanks to the spring element (6), the handles (1, 2) can be locked again. This enables them to work together again. Thanks to this working principle... The system allows the covers (7, 8) to be operated together or independently with a single mechanism. It provides flexibility and ergonomics in use by allowing it to be opened. In terms of production method, the following process steps are required to create the invention: 15 It is performed: - The right cover handle (1) and the left cover handle (2) are mechanically attached to the respective covers (7, 8). It is assembled using fasteners. - Handles so that the right (1) and left (2) handles can move together A locking mechanism (3) and a locking pin / spring element (6) are placed between them. 20 - Spring element to keep the locking mechanism (3) locked in the normal state (6) is assembled. - The right release button (4) is placed on the right handle (1); this button (4), function of temporarily disabling the latching mechanism (3). It has. 25 - The left release button (5) is placed on the left handle (2); this button (5) also has the function of temporarily disabling the locking mechanism (3). It has. - If one of the handles (1, 2) is lifted without pressing the button (4, 5) Thanks to the locking mechanism (3), the two handles (1, 2) move together and 30 The two lids (7, 8) are opened simultaneously. 8 - The locking mechanism (3) is deactivated by pressing the button (4 or 5). When released, only the relevant handle (1 or 2) moves and to which it is attached. The lid (7 or 8) opens independently.
