Description

Technical Field

[0001] This invention relates to the field of shelf technology, and particularly to prefabricated tension shelves.

Background Art

[0002] In daily life, various storage and hanging tools such as storage baskets, hanging shelves, hooks, and hanging rods are widely used to store and hang daily necessities such as clothes, shoes, and hats. When installing these hanging shelves and hanging rods indoors, conventional fixing methods using screws or adhesives are generally used, but these methods damage the wall surface. Not only do permanent damage marks remain on the wall, but the storage appliances cannot be moved and rearranged at any time during use, lacking flexibility. Furthermore, due to factors such as insufficient wall strength and stress concentration at the connection points, the fixing comes loose and the shelf falls, so there are also problems in terms of reliability.

Summary of the Invention

Means for Solving the Problems

[0003] In response to the problems of insufficient flexibility and insufficient attachment strength in the fixing method of the conventional storage appliances described in the above background art, in this case, a prefabricated tension shelf is proposed. This invention is easy to install, has reliable connection and fixing, is excellent in flexibility during installation and use, and facilitates the installation and movement operations of storage appliances.

[0004] To achieve the above object, the technical means adopted by this invention are as follows. A prefabricated tension shelf, The system comprises a modular tension support column, grounding legs, and a movable hanging frame. The ends of the modular tension support columns have internal cavities that communicate with the end faces, and detachable connecting parts are fixedly installed. Different modular tension support columns can be detachably connected to each other. The tension shelf is constructed by connecting any number of modular tension support columns. Grounding legs are provided at the outer ends of the modular tension support columns located at the outermost ends of the tension shelf, and one end of the grounding leg is a modular... The grounding leg penetrates the connection at the outer end of the support column and is housed in the internal cavity of the assembled support column. The penetrating portion of the grounding leg can form a releaseable locking fit with the connection at the end of the penetration at any position, thereby allowing the length of the grounding leg to be freely adjusted. The end of the movable hanging frame for increasing the space for placing objects is provided with a non-closed friction locking portion, and the movable hanging frame can be detachably assembled to any position on the outer surface of the assembled support column via the friction locking portion.

[0006] As a further improvement to this utility model, the protruding connection part and the through connection hole are formed with screw threads that fit together. When a pair of male and female assembly brackets are installed on adjacent ends of different assembled tension support columns, the protruding connection part and the through connection hole are fastened with screws, thereby indirectly and detachably connecting the ends of the different assembled tension support columns.

[0007] As a further improvement to this utility model, threads are formed in the through-connection holes and connecting columns that fit together. When female assembly brackets are installed at adjacent ends of different assembled tension support columns, both ends of the connecting column are screw-fastened to the female assembly brackets of the different assembled tension support columns, thereby allowing the ends of the different assembled tension support columns to be indirectly and detachably connected.

[0009] As a further improvement to this utility model, the through-connection hole and the connecting column are screw-fastened, and an additional female assembly bracket, which is independently rotatable, is screw-fastened to the connecting column. When the independently rotatable female assembly bracket is in contact with the fixed female assembly bracket, the axial distance between the support plate and the end of the assembled bracing column is kept constant.

[0010] As a further improvement to this utility model, the through-connection hole and the connecting column are fastened with screws, an independently rotatable locking plate is additionally fastened with screws to the connecting column, and an elastic member is sandwiched between the locking plate and the adjacent female assembly bracket. The expansion and contraction state of the elastic member changes according to the distance between the locking plate and the female assembly bracket, and when the elastic member is in a compressed state, the axial distance between the support plate and the end of the assembled bracing column is kept constant.

[0014] Compared to conventional technology, this utility model has the following superior effects. 1. The assembly-type tension shelf of this invention has a structure with adjustable and extendable grounding legs that abut against the installation surface. Whether installed horizontally or vertically, it secures the assembly-type tension shelf without damaging the installation surface and generates frictional force to support the stored items. It protects the installation surface, such as a wall or ceiling, and maintains its aesthetic appearance. 2. By adjusting the contact legs and increasing or decreasing the number of connecting tension shelves as needed, the assembly and disassembly of the modular tension shelf can be carried out quickly, making it possible to accommodate installation spaces with different doorways. Users can freely change the installation position according to their needs, providing high convenience. 3. Whether the tension shelf is installed vertically or horizontally, the movable hanging frame, with its spiral-shaped coiled tail, provides stable suspension or friction locking that can be quickly attached and detached.

Modes for Carrying Out the Invention

[0016] (Example 1) This will be described with reference to FIGS. 1 to 9.

[0017] This assembled protruding shelf includes an assembled protruding support column 1, a male assembled bracket 11, a female assembled bracket 12, a connecting column 13, and a grounding leg 2.

[0018] The assembled protruding support column 1 is a cylindrical member, and a storage chamber 10 is provided inside the member along the central axis from both end faces of the assembled protruding support column 1.

[0019] As shown in FIG. 5, the male assembled bracket 11 is a cylindrical part having the same diameter as the assembled protruding support column 1. On one end face of the male assembled bracket 11, a protruding connecting portion 111 extending along the central axis is formed. Four through holes are formed in the male assembled bracket 11 at equal intervals around the central axis, and the four through holes are arranged so as to surround the outside of the protruding connecting portion 111. The female assembled bracket 12 is also a cylindrical part having the same diameter as the assembled protruding support column 1, and a through connection hole 121 is formed along the central axis. Four through holes are provided annularly outside the through connection hole 121 at equal intervals. The protruding connecting portion 111 and the through connection hole 121 have the same diameter, and screw threads that fit with each other are formed on the outer peripheral surface of the protruding connecting portion 111 and the inner peripheral surface of the through connection hole 121. As shown in FIG. 4, the male assembled bracket 11 and the female assembled bracket 12 are respectively attached to the adjacent ends of two independent assembled protruding support columns 1. The male assembled bracket 11 and the female assembled bracket 12 are fixed to the ends of the assembled protruding support column 1 by inserting screws through the four through holes respectively. By screwing the protruding connecting portion 111 and the through connection hole 121, the ends of the two assembled protruding support columns 1 can be detachably connected.

[0020] The connecting column 13 is a threaded column with screw threads formed on its outer surface, and the screw threads of the connecting column 13 engage with the screw threads of the through-connection hole 121. Both ends of the connecting column 13 are column bodies with a smaller diameter than the outer diameter of the threaded portion, and their surfaces are formed to be smooth. As shown in Figure 9, annular grooves are provided on the outer circumference of both ends of the connecting column 13, and an annular retaining locking device 21 is fitted and locked into these grooves. As shown in Figure 6, female assembly brackets 12 are attached to adjacent ends of two independent assembled tension support columns 1, and each female assembly bracket 12 is fixed to the end of the assembled tension support column 1 by inserting screws through four through-holes. The ends of the two assembled tension support columns 1 are detachably connected by fastening both ends of the connecting column 13 to the female assembly brackets 12 on both sides with screws, and by screwing the ends of the connecting column 13 into the storage chamber 10. The outer diameter of the retaining locking device 21 is larger than the diameter of the through-connection hole 121, preventing loosening or detachment due to rotation of the connecting column 13.

[0021] The grounding leg 2 consists of a connecting column 13 and a support plate 20, the support plate 20 including a grounding plate 201 and an engagement plate 202. As shown in Figure 7, both the grounding plate 201 and the engagement plate 202 are disc-shaped components and are arranged with their end faces facing each other. Three screws are placed at equal intervals with respect to the central axis of the support plate 20 to fix the grounding plate 201 and the engagement plate 202 together. A non-penetrating cavity is formed in the center of the mating surface of the grounding plate 201 and the engagement plate 202, extending to both sides, forming a position-regulating cavity 203 inside the support plate 20. A through hole is drilled in the center of the engagement plate 202 to match the outer diameter of the end of the connecting column 13, and communicates with the position-regulating cavity 203. As shown in Figure 8, the smaller diameter end of the connecting column 13 is inserted into the position-regulating cavity 203 through the through hole in the center of the engagement plate 202. A retaining locking device 21 is fitted to the small-diameter end of the connecting column 13. Since the outer diameter of the retaining locking device 21 is larger than the diameter of the through hole in the center of the engagement plate 202, the end of the connecting column 13 is locked and fixed within the position-regulating cavity 203. As shown in Figure 3, one or two independent female assembly brackets 12 can be selectively screwed onto the opposite end of the connecting column 13, and a retaining locking device 21 is fitted to the end to prevent the female assembly bracket 12 from being screwed out or falling off. The female assembly bracket 12 is fixed to the end of the assembled tension support column 1 by inserting screws through four through holes (if two female assembly brackets 12 are provided, the female assembly bracket 12 closer to the end is screw-fixed to the assembled tension support column 1). In this way, the ground leg 2, consisting of the connecting column 13 and the support plate 20, and the assembled tension support column 1 are integrated. By adjusting the length to which the left end of the connecting column 13 is screwed into the storage chamber 10, the grounding leg 2 can be moved forward and backward in the axial direction.

[0022] As for the installation and usage principles, Two independent, modular tension support columns 1 are connected by a male assembly bracket 11 and a female assembly bracket 12 at their opposing ends, and grounding legs 2 are attached to the unconnected ends of each tension shelf. In the horizontal installation state shown in Figure 2, the two independent female assembly brackets 12 are screwed into the connecting column 13 of the right grounding leg 2. In the vertical installation state, the two independent female assembly brackets 12 are screwed into the connecting column 13 of the lower grounding leg 2. The horizontal installation will be explained as an example. The device is installed in a space with two support surfaces parallel to the vertical direction (e.g., between two walls). The left grounding leg 2 is abutted against the left support surface, the connecting column 13 of the right grounding leg 2 is rotated and extended to the right, and the right grounding leg 2 is abutted against the support surface on the opposite side. Next, the independent female assembly bracket 12 on the right connecting column 13 is rotated and abutted against the female assembly bracket 12 screw-fixed to the modular tension support column 1, forming a double-nut anti-loosening structure. This allows you to install a modular tension shelf between two walls and use it to hang clothes and other items.

[0023] As for the assembly and disassembly principles, To extend the overall length of a prefabricated tension shelf consisting of two prefabricated tension posts 1, as shown in Figure 1 or Figure 2, the support plate 20 of one of the grounding legs 2 is removed, and the end of the exposed connecting column 13 is connected to another prefabricated tension post 1 to which a female assembly bracket 12 is attached. This extends the overall length of the device, making it possible to install it in locations with wider openings.

[0024] As shown in Figure 1 or Figure 2, when shortening the overall length of the assembled support rod frame, which consists of two independent assembled tension posts 1, it can be disassembled and separated from the connection point between the male assembly bracket 11 and the female assembly bracket 12 located in the middle. After disassembly, by attaching the grounding legs 2 to the end of any one of the assembled tension posts 1, it becomes possible to accommodate installation in smaller openings.

[0025] (Example 2) This will be explained with reference to Figures 10 and 11.

[0026] This embodiment is based on Embodiment 1, with the addition of a movable hanging frame 3. The movable hanging frame 3 is formed by bending a rod, and one end is bent spirally to form a spiral winding tail portion 31. The pitch and outer diameter of the spiral winding tail portion 31 are larger than the outer diameter of the assembled tension support column 1, allowing it to be hooked onto the assembled tension support column 1 through the gap in the spiral. The other end of the movable hanging frame 3 is bent and formed into an annular storage frame.

[0027] As shown in Figure 10, when the modular tension shelf is installed vertically, the spiral winding tail 31 of the movable hanging frame 3 embraces the outer circumference of the modular tension support column 1. Storage trays, storage baskets, etc., can be placed on the storage frame at the other end. The weight of the stored items creates a rotational moment on the spiral winding tail 31, pressing the inner surface of the spiral diagonally against the outer surface of the modular tension support column 1, generating a vertical frictional force that fixes the movable hanging frame 3 in place.

[0028] As shown in Figure 11, when the modular tension shelf is installed horizontally, the spiral winding tail 31 stably wraps around the outer circumference of the modular tension support column 1, and the storage frame at the other end provides a variety of hanging and storage locations.

[0029] (Example 3) Please refer to Figures 12 and 13 for further explanation.

[0030] This embodiment is based on Embodiment 1, with the addition of a locking plate 14. The locking plate 14 is used as a replacement for the female assembly bracket 12 that restricts the axial movement of the grounding leg 2 relative to the assembled bracing support column 1.

[0031] As shown in Figure 13, the locking plate 14 is a cylindrical component, and a radially protruding anti-slip portion 141 is formed on its outer surface. A threaded through hole that fits the connecting column 13 is drilled in the center, and a cylindrical recess 142 is provided on one end face.

[0032] As for the installation and usage principles, As shown in Figure 12, the locking plate 14 is screw-fastened to the connecting column 13 of the grounding leg 2, and positioned at a distance from the female assembly bracket 12 which is screw-fixed to the end of the assembled bracing column 1. The end face of the locking plate 14 having the recess 142 is oriented toward the adjacent female assembly bracket 12. A spring is fitted onto the outer circumference of the connecting column 13 between the locking plate 14 and the female assembly bracket 12, with one end of the spring abutting against the end face of the female assembly bracket 12 and the other end abutting against the bottom surface of the recess 142.

[0033] During use, the locking plate 14 is rotated to bring it closer to the female assembly bracket 12, compressing the spring between them. The spring applies axial pressure in both directions, applying axial preload to the female assembly bracket 12 and the locking plate 14, which are screw-fastened to the connecting column 13, thus providing an anti-loosening effect on the screw portion. Compared to the double-nut type anti-loosening structure using two female assembly brackets 12 in Example 1, this configuration requires less effort for tightening, suppresses the problem of difficulty in loosening after fastening, and allows for easy application and release of the anti-loosening effect by preloading the screw connection portion.

[0034] The above are merely preferred embodiments of this utility model and are intended to illustrate the principle and effect of the invention, and do not limit this utility model. Various modifications, alterations, and substitutions within the scope of the technical concept and principle of this invention are all included within the scope of protection of this utility model.
