Description

[0001] Sustainable Sliding Door for Cold Storage

[0002] The present invention belongs to the technical field of mechanics, particularly to the field of profiles for door frames, specifically, it belongs to the field of profiles for door frames of refrigeration chambers, and more particularly to profiles for sliding door frames for refrigeration chambers.

[0003] BACKGROUND OF THE INVENTION

[0004] Currently, there are a large number of products that require a controlled cooling temperature for preservation. Due to this demand for consumer products, primarily refrigerated foods and beverages, and the desire to be available to consumers in stores or supermarkets, commercial refrigerators have been designed with different sizes and specific dimensions. Commercial cooling units can be found, for example, in convenience stores or supermarkets. They come in different sizes and have different numbers of glass doors, which allow a view inside when closed, to display the products.

[0005] This type of cooling unit consists of three main elements: a main frame, dividing posts, and doors. Each of these elements has essential characteristics and different assembly methods, always ensuring a thermal insulation system to prevent temperature leaks and save energy. This also ensures precise temperature control to prevent the door glass from fogging up.Furthermore, for the purpose of displaying products, commercial refrigerators have lighting in some of these 3 product elements to illuminate the products displayed in front of the cooling unit, which is why it is also necessary to have a specific lighting system; and finally, the assembly method of these 3 elements may differ according to the type of construction of the frame, posts and door, hence there is a great need to generate highly profitable solutions that save time in the assembly process. In this particular invention, the proposed solution relates to the frame of the doors of commercial cooling units, its elements and the assembly method.The types of doors used for refrigerated chambers can be classified according to their construction and operation: pivot doors are the most common, opening by rotating on a central axis; swing doors open by folding onto themselves and are ideal for small chambers; and sliding doors slide on a rail and are ideal for small chambers or chambers located in narrow spaces. The proposed invention relates to the latter, such that the system of profiles and elements comprising it allows for sliding doors with essential characteristics and functions for use in refrigerated chambers. It is known that profiles for refrigerated chambers are essential elements for the assembly of these structures. They are responsible for joining the chamber panels, providing rigidity and tightness.Cold room profiles are manufactured in a variety of materials, including PVC, aluminum, and steel. The material chosen will depend on the conditions of use of the cold room. For example, PVC profiles are suitable for domestic or commercial cold rooms, while steel profiles are more durable and are used in industrial cold rooms.

[0006] It is also known that the essential parts of a sliding cold storage door are the following: The frame is the structure that supports the door. The frame can be made of stainless steel, aluminum, or wood; The leaf is the moving part of the door. The leaf can be made of insulating materials, such as polyurethane, polystyrene, or polyurethane foam; The rail is the structure on which the door slides. The rail can be made of stainless steel, aluminum, or plastic. The bearings are the elements that allow the door to slide smoothly on the rail. The bearings can be made of stainless steel, aluminum, or plastic. The closing system is the element that keeps the door closed. The closing system can be mechanical or electromechanical.

[0007] Many products have been designed that improve some of these elements. In the prior art, we can find various documents that disclose sliding door systems. For example, document CN212987756, entitled "Sliding door structure of a refrigerated cabinet capable of automatic return," refers to a utility model that provides a sliding door structure for a refrigerated cabinet capable of automatic return. The sliding door structure of the refrigerated cabinet comprises a cabinet body and a sliding door. The sliding rails are arranged symmetrically on the cabinet body, and the sliding door is in sliding connection with the cabinet body via the sliding rails.A return assembly is mounted on the sliding rail to retract and close the sliding door; one side of the cabinet body, which is closed with the sliding door, is provided with a distance measuring sensor; when the distance measuring sensor detects that the sliding door has not been closed for a period of time, the control system controls the operation of the drive motor, such that the sliding block moves, pushing the sliding door to automatically return. However, this system does not feature a sliding door frame comprising two side frame segments with heat seals, an upper segment with a self-closing mechanism, and a lower segment with a heat seal between the door leaves and hexagonal helices for strength and durability.

[0008] Likewise, document CN211903478, named “SLIDING DOOR OF REFRIGERATED CABINET” refers to a door frame and a sliding door leaf frame of the refrigerated cabinet are both designed to be of a broken bridge thermal insulation structure, the frame profiles of the door frame and the door leaf frame are connected in an assembled mode through corner connectors, and the mounting and connection structures of the corner connectors have a firm connection and good sealing performance. Meanwhile, the upper frame of the leaf and the lower frame of the door leaf are in sealed contact with the door frame through sealing rubber strips, the installation structure of the upper pulley and the lower pulley has a reasonable design and is firm and convenient to install, and the door leaf has the advantages of having a good heat insulation effect and cold insulation, good sealing performance,Free from cold air leakage, capable of significantly reducing water mist on the outer glass surface of the door leaf, and smoothing the opening and closing of the door leaves; meanwhile, magnetic strips are arranged on the side frames of the door frame, corresponding magnetic strips are also arranged on the side frames of the door leaf, and when the door leaf is locked, the door leaf can be locked and sealed through the mutual attraction of the magnetic force between the magnetic strips, and is not prone to rebound or open. However, this system does not feature a sliding door frame comprising two side frame segments with heat seals, an upper segment with a self-closing mechanism, and a lower segment with a heat seal between the door leaves and hexagonal heles for strength and durability.

[0009] Also, document CN218716072, named “AUTOMATIC RETURN DEVICE FOR SLIDING DOOR AND REFRIGERATED CABINET# refers to an automatic return device for sliding door and a refrigerated cabinet comprising an automatic return structure and a pull-out plate, and the pull-out plate is connected to the automatic return structure in a sliding mode.When the sliding door body of the refrigerated cabinet is closed, the sliding door body drives the pull-out plate to move toward the door body closing position; when the pull-out plate is in contact with the self-returning structure, the reciprocating notch of the pull-out plate is lined with the stop pin and drives the stop pin to separate it from the bent portion of the sliding groove; at this time, the sliding plate is pulled to move under the pulling force of the telescopic spring without external action force. However, this system does not disclose a sliding door frame comprising two side frame segments with heat seals, an upper segment with a self-closing mechanism, and a lower segment with a heat seal between the door leaves and hexagonal rails for strength and durability.

[0010] TECHNICAL PROBLEM TO BE SOLVED

[0011] The aim is to provide a solution that provides a sliding door frame comprising two side frame segments with thermal seals, an upper segment with a self-closing mechanism, and a lower segment with thermal seals between the door leaves and hexagonal helices for greater strength and durability. The present invention falls within the technical field of refrigeration systems, specifically focusing on the improvement of sliding doors designed for cold storage rooms. This innovation seeks to optimize the functionality of sliding doors while integrating recycled materials, emphasizing sustainability in the design and manufacture of such doors. Sliding doors for cold storage rooms have historically used materials such as steel, aluminum, and thermoplastic polymers.These materials offer strength and durability, but growing environmental awareness has generated a growing demand for solutions that incorporate recycled materials, with the aim of reducing the ecological footprint of refrigeration facilities.

[0012] Although conventional sliding doors meet functional requirements, sustainability challenges persist. The need to address waste generation and promote eco-efficient practices in the refrigeration industry is driving the search for solutions that effectively integrate recycled materials into sliding doors. The present invention provides a significant improvement in sliding doors for cold storage rooms through the introduction of recycled composite materials. These materials not only improve the doors' strength and thermal efficiency but also address environmental challenges through the responsible use of recycled resources, thereby contributing to sustainability in the refrigeration sector. The central innovation of the invention is based on the application of recycled composite materials to the manufacture of sliding doors.These materials comprise a recycled matrix, possibly derived from post-consumer plastics or industrial waste, reinforced with recycled fibers, such as reclaimed fiberglass. This combination not only offers high strength and durability but also directly contributes to waste reduction and the circular economy. The integration of recycled composite materials presents significant advantages. In addition to improved structural strength and thermal efficiency, these benefits include reduced dependence on non-renewable natural resources, a reduced carbon footprint, and the promotion of sustainable practices. Furthermore, the use of recycled materials fosters environmental awareness and meets growing sustainability expectations in the design of cooling solutions.

[0069] DETAILED DESCRIPTION OF THE INVENTION This chapter describes a Sliding Door for a Refrigeration Chamber (10), represented in Figures 1 to 58. This description is solely by way of example and is not intended to limit the scope of the invention, since other embodiments and variations of the invention are also considered within the claims. The Sliding Door for a Refrigeration Chamber (10) comprises a frame system consisting of a refrigerated chamber frame and two door frames, where the refrigerated frame has 2 rails so that each of the door frames can move to open and close the refrigeration chamber.The frame of the refrigerated chamber has two side sections (200), one side section (200) on the right side and another side section (200) on the left side, it also has an upper section (300) that joins the side sections (220), and a lower section (400) that joins the side sections and that has rail profiles (410) so that the two door frames can slide and move to open and close the refrigerated compartment.

[0070] The side sections (200), the upper section (300) and the lower section (400) have an assembly of 2 profiles that form the structure of the door frame, in addition, each section has additional elements to hold the door frames so that it slides on the rails, has an automatic closure and at the same time meets thermal insulation requirements. The assembly of 2 profiles is made up of an aluminum profile (500), preferably made of metal and a plastic profile (600), preferably made of plastic materials.

[0071] The aluminum profile (500) has a first wall (501) where one of its front sides will be the front of the refrigerated frame and on its inner face it has a second wall (502) and a third wall (503) projected substantially perpendicularly from the first wall (501); likewise, it has a fifth wall (505) parallel to the first wall (501), projected from one end of the second wall (502) to the end of the third wall (503); it also has a fourth wall (504) parallel to the first (501) and fifth (505) walls, which projects from the second wall (502) to the third wall (503); the fourth wall (504) is located between the first wall (501) and the fifth wall (505).

[0072] The aluminum profile (500) also has fastening elements to be assembled with the plastic profile (600); it has a first fastener (506) located on the first wall (501), projected next to the third wall (503); it has a second fastener (507) located on the rear face of the fifth wall (505), taking as a reference that the face of the fifth wall (505) oriented towards the first wall (501) is its front face. The first fastener (506) consists of a male type element that will be inserted into a female type element of the plastic profile (600). The second fastener (507) comprises a pair of fasteners that are anchored in the second fastener (612) of the plastic profile (600).

[0073] The aluminum profile (500) also has a support (508) projected from the first wall (501), located next to the first fastener, on the opposite side to where the third wall (503) is located. The support (508) has the function of supporting one side of the rail profile (410).

[0074] For its part, the plastic profile (600) has a first wall (601) that, in the assembly with the aluminum profile (500), is parallel to the first wall (501) of the aluminum profile (500). The first wall (601) is the wall that remains towards the interior of the refrigerated frame; it has a second wall (602) and a third wall (603) projected substantially parallel from the first wall (601), with a separation between them such that their ends form the first fastener (611); likewise, the plastic profile (600) has a fourth wall (604) projected perpendicularly from the first wall (601) to one side of the third wall (603), on the opposite side to where the second wall (602) is located. Also, the plastic profile (600) has a support (616) projected perpendicularly from the first wall (601) to one side of the second wall (602), on the opposite side to where the third wall (603) is located.

[0075] In the section of the fifth wall (605) projecting from the fourth wall (604) to the third wall (603) there is the second fastener (612), which is located on the front face of the fifth wall (605). The second fastener (612) comprises a pair of fasteners that are anchored in the fasteners of the second fastener (507) of the aluminum profile (500).

[0076] The plastic profile (600) has a fifth wall (605) projected perpendicularly from the end of the fourth wall (604), of a length such that it crosses the third wall (603) and second wall (602). Likewise, the plastic profile (600) has a sixth wall (606) projected perpendicularly from the third wall (603), of a length such that it crosses the third wall (603) and its end, together with the end of the fifth wall (605) form the third female type fastener (613). The plastic profile (600) has a seventh wall (607) and an eighth wall (608) projected perpendicularly from the second wall (602), located next to the sixth wall (606), on the opposite side to where the fifth wall (605) is located. The separation between the seventh wall (607) and the eighth wall (608) and the length of its projection is such that the ends of both walls form a fourth female-type fastener (614).The plastic profile (600) has a ninth wall (609) and a tenth wall (610) projected perpendicularly from the second wall (602), located next to the eighth wall (608), on the opposite side to where the seventh wall (607) is located. The separation between the ninth wall (609) and the tenth wall (610) and the length of its projection is such that the ends of both walls form a fifth female-type fastener (615).

[0077] Figures 17 and 18 show a segment of the assembly of the aluminum profile (500) with the plastic profile (600), where the first fastener (506) is inserted into the first fastener (611); while the fasteners of the second fastener (507) are anchored in the fasteners of the second fastener (612).

[0078] The lower segment (400) of the assembly of the aluminum profile (500) with the plastic profile (600), that is, the segment that is positioned at the base of the frame of the refrigerated compartment also comprises a thermal seal (110) to isolate temperature, a pair of rail profiles (410) to form the slides where the sliding doors move, and a pair of hexagonal bars (420) as guides where the sliding doors will run. The rail profile (410) is an element that has a rail wall (411), in its lower part it has fasteners (412) that have the function of being inserted into the fifth fastener (615) or in the third fastener (613) of the plastic profile (600); in its upper part it has a channel (413) for the placement of the hexagonal bar (420). The lower segment (400) has a rail profile (410) inserted into the third fastener (613) and another rail profile (410) inserted into the fifth fastener (615).Similarly, each channel (413) has a hexagonal bar (420) placed so that the bearing (760) of each door rolls on the bar to open and close the door of the refrigerated compartment.

[0079] The side segment (200) of the assembly of the aluminum profile (500) with the plastic profile (600) has elements that allow it to couple with the sides of the doors. The Sliding Door for Refrigeration Chamber (10) has 2 doors that run parallel and independently and on rails and on independent hexagonal bars; when the refrigerated compartment is open, each door covers one side of the width of the frame, that is, each door is positioned and coupled in a side segment (200) of the aluminum profile assembly (500). When the refrigerated compartment is closed, one door is coupled on the right side of the side segment (200) of the aluminum profile assembly (500) with the plastic profile (600) and another door is coupled on the left side of the side segment (200) of the aluminum profile assembly (500) with the plastic profile (600).Therefore, the side segment (200) has two elements to adapt it to any of the modalities, left or right, of the side segment (200). The side segment (200) of the assembly of the aluminum profile (500) with the plastic profile (600) has a seal holder profile (210) and a cover profile (220) that has the function of being inserted into the fifth fastener (615) or into the third fastener (613) of the plastic profile (600) according to the desired modality, left or right, of the side segment (200).

[0080] The seal holder profile (210) comprises a channel of such a width that allows its insertion into the fifth fastener (615) or in the third fastener (613) of the plastic profile (600), it also has a pair of sides (212) perpendicular to the walls of the channel and a pair of fasteners (210) on the outer wall of the channel, and together they have the function of anchoring the seal holder profile (210) in the fifth fastener (615) or in the third fastener (613) of the plastic profile (600). In each seal holder (210) there is a seal (110) that allows blocking the passage of air when the door is in place and maintaining better temperature control. The cover profile (220) has a cover wall (221) of a width greater than the width of the fifth fastener (615) or in the third fastener (613) of the plastic profile (600), in such a way that it covers the width of the fasteners.Likewise, in its lower part it has a pair of fasteners (222) that have the function of anchoring in the fifth fastener (615) or in the third fastener (613) of the plastic profile (600). The cover profile (220) has the function of being the stop when a door is slid to open it and it travels to the end of its track. The upper segment (300) of the assembly of the aluminum profile (500) with the plastic profile (600) has two closing springs (310), one inserted in the fifth fastener (615) and another inserted in the third fastener (613) of the plastic profile (600). Each closing spring (310) is attached to the upper part of each door profile (700) and has the function of moving back and along the door profile (700) when the door is opened.The closing spring (310) has the function of keeping the door closed unless the user moves it to open it, therefore, each closing spring (310) keeps the doors coupled in the lateral segment, left or right, that corresponds to it and where there is a seal (110) to generate a hermetic closure.

[0081] In all the assembly modalities of the aluminum profile (500) with the plastic profile (600): left side section (220), right side section (220), upper section (300) and lower section (400), there are seals (110), placed in the fourth fastener (614) of each segment to isolate and separate the air between each of the doors, in such a way that an isolated temperature is maintained. On the other hand, as an essential element of the Sliding Door for Refrigeration Chamber (10), there are the two sliding doors that run in the assembly of the aluminum profile (500) with the plastic profile (600); the doors comprise a frame with segments of Door Profile (700) and a glass package (730). The frame of each door has an upper door profile segment (700), a lower door profile segment (700), a side door profile segment (700) and a door profile segment (700) with a handle.The door profile (700) has a first wall (701) that has an outer face that will be oriented towards the front of the door; it also has a second wall (702) and a third wall (703) projected perpendicularly from the inner face of the first wall (701), both with a length such that at its ends there is a fourth wall (704) substantially parallel to the first wall (701). The fourth wall (704) is of such a length that one is attached to the second wall (702) and the other end is projected to the same length as the end of the first wall (701).Likewise, the door profile (700) has a bead fastener (705) in the outer corner of the junction of the second wall (702) and the fourth wall (704); it also has pairs of fasteners placed in parallel on the inner faces of the first wall and the fourth wall (704); the face fasteners (707) are located parallel at the ends of the first wall (701) and the fourth wall (704); while the bearing fasteners (706) comprise a pair of notches, one located in the first wall (701) and another located in the fourth wall (704), both parallel and located between the face fasteners (707) and the second wall (702).

[0082] The frame of each door has segments of Door Profile (700) that have a reinforcement (710) located in the concavity formed by the first wall (701), the second wall (702), the third wall (703) and the fourth wall (704), where said reinforcement is of a rigid material and provides strength to the assembly of the door profile segments (700). The frame of each door has segments of Door Profile (700) that have fastening elements for the placement of the glass package (730) and its adequate fixation to immobilize it within the frame.
