Description

A foldable load-bearing component and load-bearing platform Technical Field

[0001] This invention relates to the field of electrical appliance accessories technology, specifically to a foldable support component and support platform. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Existing front-loading washing machines, with their side-opening doors, make it easy for clothes to fall out when taking them out. Small items, in particular, lack a place to be temporarily stored. Therefore, there is a need for a support platform that can open and close synchronously with the washing machine door to temporarily place some clothes.

[0004] A search revealed a Chinese invention patent with patent application number CN202311277870.9, which discloses a clothes receiving platform for a drum washing machine. The support platform in the aforementioned invention patent does not have a strong load-bearing capacity. In order to improve the load-bearing capacity, a folding frame is added to the invention. However, the folding frame needs to be purchased separately or produced on a separate production line. After production, it needs to be further assembled, which is not conducive to improving production efficiency and reducing production costs. Summary of the Invention

[0005] The main objective of this invention is to provide a foldable load-bearing component and load-bearing platform that can enhance load-bearing capacity and has high production efficiency.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a foldable support component includes a support portion that is continuously folded in a V-shape, one end of the support portion is folded together to form a rotation center, and the support portion can be unfolded and folded around the rotation center;

[0007] The supporting part has multiple fan blades connected together in a V-shape; the supporting part is provided with a reinforcing part, which is located at the connection between two fan blades to enhance the supporting strength of the supporting part.

[0008] Furthermore, the reinforcing part is a reinforcing structure formed by joining two adjacent fan blades together.

[0009] Furthermore, the reinforcing structure is one or more joint points formed between two adjacent fan blades near the crease line.

[0010] Furthermore, the reinforcing structure is one or more joint lines formed between two adjacent fan blades near the crease line.

[0011] Furthermore, the connecting line is a continuous line or multiple line segments spaced apart.

[0012] Furthermore, the joint points do not completely coincide with the crease line, and are used to reconnect adjacent fan blades to form a reinforcing structure; when there are multiple joint points, the multiple joint points are arranged in a straight line and parallel to the crease line, or the multiple joint points are arranged in an oblique line and start from one end near the rotation center of the support part, distributed along the length direction of the fan blade, and gradually approach the crease line.

[0013] Furthermore, the joining line does not completely coincide with the crease line, and is used to reconnect adjacent fan blades to form a reinforcing structure; the joining line is parallel to the crease line, or the joining line is oblique, starting from one end near the rotation center of the support part and gradually approaching the crease line along the length of the fan blade.

[0014] Furthermore, the supporting part is an integral structure, forming folded fan blades through creases; or the supporting part is a split structure, formed by multiple independent fan blades connected in a V-shape.

[0015] Furthermore, the supporting part is composed of a folded structure and an assembled structure connected together. The folded structure forms mutually folded fan blades through creases, and the assembled structure is composed of multiple independent fan blades connected together in a V-shape.

[0016] Furthermore, the end of the support portion furthest from the center of rotation curves upward.

[0017] Furthermore, a clamping component is provided at one end of the supporting part corresponding to its own rotation center, and the clamping component is used to fold and clamp one end of the supporting part together.

[0018] Furthermore, the reinforcing part includes a reinforcing plate disposed at the connection between two adjacent fan blades, one end of which extends into the clamping member and is clamped by the clamping member.

[0019] Furthermore, the fan blades are made of flexible fabric and / or mesh.

[0020] Furthermore, a fence is provided at the end of the support part away from the rotation center. The fence includes a frame and multiple rails. The multiple rails are connected to the connection points and / or reinforcements of two fan-shaped parts at the same height. The frame is installed at the end of the support part through the rails and unfolds together with the support part.

[0021] Furthermore, the support is installed in an inclined position, wherein one end of the support corresponding to its own rotation center faces downward, and the other end of the support away from the rotation center faces upward.

[0022] Furthermore, it also includes a first magnetic attraction component and a second magnetic attraction component located on both sides of the support portion along its length. When the support portion is folded, the first magnetic attraction component and the second magnetic attraction component attract each other.

[0023] A foldable carrying platform, employing the aforementioned foldable carrying component, further includes a fixed end face and a movable end face located on both sides of the support portion along its length and connected to the fan-shaped plates on both sides of the support portion.

[0024] The fixed end face is used to fix the loading platform to the bottom of the opening and closing door of the object to be installed;

[0025] The movable end face is connected to the opening and closing door of the object to be installed. When the opening and closing door is opened, the supporting part of the garment receiving platform is opened by the movable end face; when the opening and closing door is closed, the supporting part of the garment receiving platform is stacked and stored by the movable end face.

[0026] Furthermore, the movable end face is connected to the opening and closing door of the object to be installed via a connection point.

[0027] Furthermore, the first magnetic attraction component and the second magnetic attraction component are respectively disposed on the fixed end face and the movable end face.

[0028] Furthermore, the fixed end face is a box with one side open, and the load-bearing component in the folded state is located inside the box;

[0029] The movable end face is a cover. One side of the cover is connected to the box body and can rotate relative to the box body. When the door is closed, the cover drives the carrying component to be stored in the box body and covers the open side of the box body.

[0030] The beneficial effects of this invention are reflected in:

[0031] In this invention, the reinforcement section enhances the support strength of the support section when it unfolds, thereby increasing its load-bearing capacity and the overall load-bearing capacity of the support platform. Compared with existing technologies, the structure is simpler, production efficiency is higher, and the reinforcement section can be directly installed during the production of the support section without the need for a separate assembly line, making production costs easier to control.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the invention, and not all of them. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0050] See Figures 1 through 15.

[0051] This invention discloses a foldable support component, including a support part 1 that is continuously folded in a V-shape (also known as a continuous W-shape fold or a continuous M-shape fold). One end of the support part 1 is folded together to form a rotation center. The support part 1 can be unfolded and folded around the rotation center. A fixed end face 2 is provided on one side of the support part 1 along its length, and a movable end face 3 is provided on the other side of the support part 1 along its length. The support part 1 can be unfolded to support materials. The fixed end face 2 is used to fix one side of the support part 1 to the body of the object to be installed, and the movable end face 3 is used to fix the other side of the support part 1 to the opening and closing door of the object to be installed, so that the support part 1 can be unfolded synchronously when the opening and closing door of the object to be installed is opened.

[0052] The support part 1 has multiple fan blades 11, with one end of two adjacent fan blades 11 connected together (or multiple fan blades 11 connected together in a V-shape / W-shape / M-shape); the support part 1 is provided with a reinforcing part, which is located at the connection of two fan blades 11 to enhance the support strength of the support part 1.

[0053] In specific implementation, the aforementioned V-shape can be an upward-facing V-shape or a downward-facing V-shape. The reinforcing part can be located on the upper part of the supporting part 1, the lower part of the supporting part 1, or any other position. The reinforcing part can increase the supporting strength of the supporting part 1 when it is unfolded, thereby improving the supporting capacity of the supporting part 1 and the overall supporting capacity of the load-bearing component. Compared with the prior art, the structure is simpler and the production efficiency is higher. The reinforcing part can be directly set on the supporting part 1 during the production process, eliminating the need for a separate assembly line and making production costs easier to control.

[0054] Preferably, the support part 1 can be made of flexible materials such as PP (polypropylene), PET plastic (polyterephthalic acid plastic) or PVC (polyvinyl chloride), with a material thickness of 0.1-0.6 mm.

[0055] Preferably, the fixed end face 2 and the movable end face 3 are fixed to the object to be installed by means of adhesive and / or magnetic attraction.

[0056] The supporting part 1 can be made from a single sheet of material folded together, or it can be made from multiple independent fan-shaped pieces 11 connected in sequence. Alternatively, one part can be made from a single sheet of material folded together, and another part can be made from multiple independent fan-shaped pieces 11 connected in sequence, and then the parts can be arbitrarily combined and connected together.

[0057] In one embodiment, the reinforcing part is a reinforcing structure 12 formed by joining two adjacent fan blades 11 together. This reinforcing structure 12 improves the overall support capacity of the support part 1. This method has a simpler structure, lower production cost, and the overall thickness of the support part 1 remains almost unchanged.

[0058] It should be noted that the two adjacent fan blades 11 can be tightly joined together at the corresponding reinforcing structure 12 positions, or they can have a certain gap. However, this gap will not allow the two joined fan blades 11 to open normally, and the included angle after the two joined fan blades 11 are opened will be smaller than the included angle when they are normally opened.

[0059] It should be noted that there are many ways to combine two adjacent fan blades 11 together, such as sewing, heat sealing, or bonding.

[0060] The reinforcing structure 12 consists of one or more joints formed near the crease line between two adjacent fan blades 11. These joints do not completely coincide with the crease line and are used to reconnect adjacent fan blades to form a reinforcing structure. When there are multiple joints, they are arranged in a straight line parallel to the crease line, or they are arranged diagonally, starting from the end closest to the rotation center of the support 1 and distributed along the length of the fan blade 11, gradually approaching the crease line. Furthermore, while multiple joints are arranged in a straight line, they can also be arranged vertically to form multiple sets of straight-lined joints.

[0061] The reinforcing structure 12 can also be one or more connecting lines formed near the fold line between two adjacent fan blades 11; the connecting lines can be continuous lines or multiple spaced line segments, and the connecting lines do not completely coincide with the fold line, used to reconnect adjacent fan blades to form a reinforcing structure; the connecting lines are parallel to the fold line, or the connecting lines are oblique lines, starting from one end near the rotation center of the support part 1 and gradually approaching the fold line along the length direction of the fan blade 11. In addition, there can be multiple connecting lines distributed vertically.

[0062] Furthermore, multiple reinforcing parts may be provided and distributed at intervals on the support part 1. Of course, multiple reinforcing parts may also be continuously distributed on the support part 1, and when continuously distributed, they may be distributed at the top and / or bottom of the support part 1.

[0063] Preferably, the reinforcing part extends from one end of the supporting part 1 to the other end of the supporting part 1. Of course, the extension of the reinforcing part can be a continuous extension or a discontinuous extension segment by segment or point by point. Of course, there can also be a certain distance between the reinforcing part and the two ends of the supporting part 1.

[0064] It should be noted that "the joint line is oblique, starting from the end near the rotation center of the support part 1 and gradually approaching the fold line along the length of the fan blade 11". This type of joint line distribution can form a triangular plate-shaped reinforcing structure 12 at the top and / or bottom of the support part 1, which can better improve the support effect. On the other hand, since the oblique line starts from the end near the rotation center of the support part 1 and gradually approaches the fold line along the length of the fan blade 11, the vertical distance between the end of the support part 1 at the rotation center and the fold line is the largest, while the vertical distance between the end of the support part 1 away from the rotation center and the fold line is the smallest. This can reduce the influence of the reinforcing part on the unfolded state of the support part 1, and will not make the end of the support part 1 away from the rotation center unable to unfold or unfold too small. Moreover, it will make the end of the support part 1 at the rotation center difficult to unfold, and the setting of the clamping component 14 can be directly eliminated, as it has some of the effects of the clamping component 14 itself.

[0065] In one embodiment, a clamping member 14 is provided at one end of the support portion 1 corresponding to its own rotation center. The end of the support portion 1 corresponding to its own rotation center is folded together and clamped by the clamping member 14. This design allows the clamping member 14 to provide radial tensile force to the support portion 1, enhancing structural stability, preventing edge sagging, and further improving the load-bearing capacity of the support portion 1. The clamping member 14 can be made into a sleeve shape. After folding the end of the support portion 1, it is fitted into the sleeve, and then a stud or other component is used to fix the end of the support portion 1 inside the sleeve. Of course, the clamping member 14 can also directly adopt other clamping methods in the prior art.

[0066] In one embodiment, the reinforcing part includes a reinforcing plate 13 disposed at the connection between two adjacent fan blades 11. This design further enhances the load-bearing capacity of the support part 1 through the reinforcing plate 13. Furthermore, compared to a support part 1 formed by continuous folding, a support part 1 composed of multiple fan blades 11 is easier to install with the reinforcing plate 13 and can be directly integrated into existing assembly lines. Of course, a reinforcing plate 13 can also be provided on a support part 1 folded from a single sheet of material. For example, the reinforcing plate 13 can be fixed to the material to be folded before folding, and then automatically integrated during the folding process. Alternatively, the reinforcing plate 13 can be fixed to the reinforcing structure 12 through additional processes to further enhance the load-bearing capacity of the support part 1.

[0067] In one embodiment, the fan blade 11 is made of flexible fabric and / or mesh, and one end of the reinforcing plate 13 extends into the clamping member 14 and is clamped by the clamping member 14. In specific implementation, since the supporting part 1 has a large rebound force when folded, when the supporting part 1 is installed on the drum washing machine, the side door of the drum washing machine is easily popped open by the rebound force of the supporting part 1. Moreover, after adding the reinforcing plate 13, the thickness of the supporting part 1 will increase significantly. Therefore, in this solution, based on adding the reinforcing plate 13, the fan blade 11 is made of a relatively thin and non-rebounding flexible fabric and / or mesh, and then one end of the reinforcing plate 13 extends into the clamping member 14 and is clamped by the clamping member 14. This ensures the load-bearing capacity of the supporting part 1 and reduces the rebound force of the supporting part 1.

[0068] Preferably, the flexible fabric is a common fabric on the market, such as cotton, linen, silk, wool, man-made fiber, synthetic fiber, blended fabric, etc.

[0069] When one end of the reinforcing plate 13 is inserted into the clamping member 14 and held by the clamping member 14, the material of the reinforcing plate 13 can be made of PP (polypropylene), PET plastic (polyterephthalic acid plastic), PVC (polyvinyl chloride), or even metal sheet. When one end of the reinforcing plate 13 is not inserted into the clamping member 14 (at this time, the fan blade 11 is not made of flexible cloth and / or mesh) or rotates with the clamping member 14, the reinforcing plate 13 can also be made of materials such as rigid plate or steel sheet.

[0070] In one embodiment, the end of the support portion 1 furthest from the center of rotation is curved upwards. Of course, both ends of the support portion 1 can be curved upwards.

[0071] Specifically, the "upward curve" can be an upward arc or a diagonal upward straight curve (it doesn't need to curve too much, just a slight upward curve is enough; the main purpose is to use this upward curve to adjust the stress and prevent the middle of the support part 1 from collapsing). For the support part 1, which is made from a single sheet of material folded together, it can be manufactured using existing injection molding processes. For the support part 1, which is made from multiple independent fan-shaped pieces 11 connected in sequence, the fan-shaped pieces 11 can be directly cut into the shape with corresponding upward curves, and then assembled. After assembly, the end of the support part 1 furthest from the center of rotation will curve upward.

[0072] By raising one end of the support part 1 upwards, the load-bearing capacity of the support part 1 is further improved, and the clothes are less likely to slip off the support part 1. The structure is simpler, the production cost is lower, and the overall thickness of the support part 1 is not increased when folded.

[0073] In one embodiment, a fence 4 is provided at the end of the support part 1 away from the rotation center. The fence 4 includes a frame 41 and a plurality of rails 42. The plurality of rails 42 are connected to the connection and / or reinforcement of two fan blades 11 at the same height. The frame 41 is installed at the end of the support part 1 through the rails 42 and unfolds together with the support part 1.

[0074] In specific implementation, the frame 41 is made of a flexible material, which can be made of fabric or the same material as the support part 1. Crease lines corresponding to the support part 1 can be provided on the frame 41. When the support part 1 is folded, the frame 41 folds along with it under the action of the support rod 42, and unfolds together with the support part 1. The support rod 42 can be a rigid rod or a rigid plate, connected to the end of the support part 1 by bonding, heat sealing, or sewing. Furthermore, in the continuous V-shapes formed by folding, the tips of each V-shape at the same height (i.e., the connection point of two adjacent fan-shaped sections 11 in the V-shape) are all provided with support rods 42. While the frame 41 is connected to the support rod 42, the two ends of the corresponding fixed end face 2 and movable end face 3 of the frame 41 are also connected to the fixed end face 2 and movable end face 3. Of course, the bottom of the frame 41 can also be connected to the tip of the V-shape simultaneously.

[0075] In this application, the fence 4 not only prevents objects from sliding off the support 1, but also enhances the load-bearing capacity of the support 1, making the middle of the support 1 less likely to collapse.

[0076] In one embodiment, the support portion 1 is installed in an inclined position, wherein one end of the support portion 1 corresponding to its own rotation center faces downward, and the other end of the support portion 1 away from the rotation center faces upward.

[0077] In practice, since the height of the unfolded end of the support part 1 will naturally decrease when it is unfolded (this is an inherent characteristic of this type of fan when it is unfolded), when installing the supporting component of this application, the support part 1 can be installed in an inclined position, with the end of the support part 1 away from the center of rotation installed obliquely upward. This can prevent clothing and other materials on the support part 1 from sliding down.

[0078] In one embodiment, the support portion 1 is further provided with a first magnetic attraction component and a second magnetic attraction component located on both sides of its length. When the support portion 1 is folded, the first magnetic attraction component and the second magnetic attraction component attract each other. This design reduces the rebound force of the support portion 1 when folded. When this support component is installed on a drum washing machine, the first magnetic attraction component and the second magnetic attraction component prevent the side door of the drum washing machine from being pushed open by the rebound force of the support portion 11, ensuring that the side door of the drum washing machine can be reliably closed.

[0079] Preferably, the first magnetic attraction component and the second magnetic attraction component can be permanent magnets.

[0080] The present invention also discloses a foldable carrying platform, which adopts the above-mentioned foldable carrying component and further includes a fixed end face 2 and a movable end face 3 located on both sides of the support part 1 along the length direction and connected to the fan blades 11 on both sides of the support part 1.

[0081] The fixed end face 2 is used to fix the loading platform to the bottom of the opening and closing door of the object to be installed;

[0082] The movable end face 3 is connected to the opening and closing door of the object to be installed. When the opening and closing door is opened, the supporting part 1 of the clothing receiving platform is unfolded by the movable end face 3. When the opening and closing door is closed, the supporting part 1 of the clothing receiving platform is stacked and stored by the movable end face 3.

[0083] The movable end face 3 is connected to the opening and closing door of the object to be installed through a connection point, so that the opening and closing door can also drive the support part 1 to unfold even when the rotation axis of the support part 1 is not on the same axis as that of the opening and closing door.

[0084] The first magnetic attraction component and the second magnetic attraction component are respectively disposed on the fixed end face 2 and the movable end face 3. This facilitates the installation and replacement of the magnetic attraction components.

[0085] The fixed end face 2 is a box with one side open, and the load-bearing component in the folded state is located inside the box.

[0086] The movable end face 3 is a cover. One side of the cover is connected to the box body via a flexible connecting piece and can rotate relative to the box body. When the door is closed, the cover drives the storage component to be stored inside the box body and covers the open side of the box body. This design allows the storage component to be stored inside the box body, which not only looks more aesthetically pleasing from the outside but also prevents the storage component from accumulating dust and getting dirty, thus soiling clothing.

[0087] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0088] It should be noted that if the embodiments of the invention involve directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0089] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B. Additionally, if the embodiments of the invention involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more. Moreover, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the invention.
