Description

Technical Field

[0001] This invention relates to the field of cat tree technology, specifically a composite cat tree. Background Technology

[0002] With the increasing number of pet-owning households and growing awareness of pet welfare, providing cats with appropriate furnishings that suit their natural instincts has become an important aspect of modern pet ownership. Cat beds and cat trees, as two core types of pet furniture, play a crucial role in meeting the physiological and behavioral needs of cats.

[0003] Cat beds primarily provide cats with a quiet, warm, and enclosed independent resting space to meet their needs for sleep and a sense of security and privacy. Cat trees, on the other hand, are designed based on a deep understanding of felines' natural instincts to climb, jump, scratch, and explore from elevated positions, aiming to address the limitations imposed on cats' activity areas by modern home spaces. They have evolved from early simple scratching posts or single climbing structures into comprehensive product systems that integrate animal behavior, engineering mechanics, and home aesthetics.

[0004] However, cat beds and cat trees currently on the market have obvious functional limitations and structural defects: First, these two types of furniture are typically designed and sold as functionally independent and separate pieces. Cat beds only provide a resting function, while cat trees focus on activity and scratching. Their functions are limited, failing to achieve a natural connection and efficient space utilization in a cat's integrated "rest-activity" scenario.

[0005] Secondly, existing products are mostly fixed-size, monolithic structures, lacking modular design. This makes them unable to flexibly adapt to the size and layout of users' actual living spaces, and also difficult to cope with changes in the number of cats in the household (such as adding a new cat). Users often need to purchase multiple independent and incompatible products, which not only takes up too much living space and causes a cluttered layout, but also limits the possibility of functional expansion.

[0006] Therefore, how to overcome the above-mentioned defects has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0007] To address the technical problems in the background art, this invention discloses a composite cat climbing frame.

[0008] This invention provides a composite cat tree climbing frame, comprising at least one basic unit module; The basic unit module is a rectangular box structure, consisting of six plates, including: Two symmetrically arranged and vertically extending first side panels; Two symmetrically arranged and vertically extending second side panels; A top plate and a bottom plate, both extending horizontally and parallel to each other; The first side plate and the second side plate are joined together in the circumferential direction to form a rectangular cylindrical main frame. The adjacent edges are connected by tenons and slots to achieve a tenon-slot connection. The top and bottom plates are fixed to the top and bottom of the main frame respectively by metal connectors to form the box, and its interior space forms a place for the cat to rest and move around. The first side panel has multiple scratch holes running through its thickness for cats to scratch. The second side panel has a doorway that extends through its thickness for entry and exit; The top and bottom plates have climbing holes that run through their thickness, allowing cats to pass vertically. The first and second side plates are provided with tenons and slots at the top and bottom edges in the vertical direction, so that adjacent basic unit modules can be connected in the vertical direction through tenon and slot slots to achieve vertical stacking expansion; The basic unit modules expand horizontally by connecting horizontally.

[0009] Furthermore, the first side plate has an integrally formed first protrusion plate on each of its left and right edges in the horizontal direction; The second side plate has an integrally formed second protrusion on each of its left and right edges in the horizontal direction; Both the tenon and the slot are located at the upper and lower edges of the first and second protruding plates.

[0010] Furthermore, the slot is located in the root transition region between the first protruding plate and the first side plate to which it is connected, and in the root transition region between the second protruding plate and the second side plate to which it is connected.

[0011] Furthermore, when the basic unit modules are spliced ​​together, the lower end of the upper first side plate is attached to the upper end of the lower first side plate; The lower end of the upper second side panel is attached to the upper end of the lower second side panel.

[0012] Furthermore, the upper end of the first convex plate is flush with the upper end of the first side plate, and the lower end is spaced apart from the lower end of the first side plate. The lower end of the second convex plate is flush with the lower end of the second side plate, and the upper end of the second convex plate is spaced apart from the upper end of the second side plate.

[0013] Furthermore, the gripping holes are in both upright and inverted Y-shapes.

[0014] Furthermore, the metal connector consists of three mutually perpendicular connecting plates: a first connecting plate, a second connecting plate, and a third connecting plate, wherein: The first connecting plate is fixedly connected to the inner side of the first side plate; The second connecting plate is fixedly connected to the inner side of the second side plate; The third connecting plate is fixedly connected to the top plate or bottom plate; Metal connectors are evenly distributed along the four corners of the top or bottom plate.

[0015] Furthermore, the first side panel, the second side panel, and the top and bottom panels are made of wood.

[0016] Furthermore, the doorway is located in a slightly higher position.

[0017] Furthermore, the climbing hole is hexagonal with rounded corners; The climbing holes that are adjacent to each other are staggered.

[0018] The beneficial effects of this invention are: 1. The cat bed, cat tree, and scratching post are integrated into the same basic unit module. By setting scratch holes, doorways, and climbing holes, the complex needs of cats for rest, activity, scratching, and vertical passage are met at the same time. This achieves a natural connection between the "rest-activity" scenarios and improves the efficiency of space utilization.

[0019] 2. The basic unit module adopts a standardized cuboid box structure, which can be stacked and expanded vertically through tenon and mortise joints, or expanded horizontally through horizontal abutment. Users can freely choose to combine one or more units according to the actual space size, apartment layout, or number of cats to form diverse shapes and size adaptations, breaking through the space limitations of traditional fixed structures.

[0020] 3. The modules can be quickly assembled by using tenons and slots without the need for additional tools or complex fixing; the overall structure is reinforced by metal connectors between the top and bottom plates to ensure overall stability after stacking or placing side by side. It can be placed directly on a flat surface without the need for wall or ground fixing, making it easy to move and rearrange.

[0021] 4. The modular design allows users to flexibly adjust the size and form of the product according to their living environment. It can be used in small spaces as a single unit, or expanded with multiple units to meet the needs of large spaces or multi-cat families. This effectively avoids the problems of repeated purchases and space clutter caused by functional separation and fixed size.

[0022] 5. All basic unit modules have a unified structure, and the panels can be produced through standardized processes. The tenon and mortise connection method simplifies the manufacturing and assembly process, which is conducive to large-scale production and cost control. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0026] Example 1: like Figure 1 and Figure 2 As shown, this invention discloses a composite cat climbing frame, which is a basic unit module 1. The basic unit module 1 is a cuboid box structure composed of six plates, including: two symmetrically arranged and vertically extending first side plates 2; two symmetrically arranged and vertically extending second side plates 3; a top plate 4a and a bottom plate 4b, both of which extend horizontally and are parallel to each other.

[0027] The first side panel 2, the second side panel 3, the top panel 4a, and the bottom panel 4b are made of wood, but can be made of wood-based panels, or even solid wood. This configuration allows for mass production, mechanized mass production, high processing efficiency, low cost, and high cost-effectiveness.

[0028] The first side plate 2 has an integrally formed first protruding plate 22 on its left and right edges in the horizontal direction; the second side plate 3 has an integrally formed second protruding plate 32 on its left and right edges in the horizontal direction; both the upper and lower edges of the first protruding plate 22 and the second protruding plate 32 are provided with tenons 5 and slots 6. The adjacent edges of the first side plate 2 and the second side plate 3 are connected by the tenons 5 and the slots 6 to form a tenon-and-groove joint, so that the first side plate 2 and the second side plate 3 are circumferentially enclosed to form a rectangular cylindrical main frame.

[0029] The slot 6 is located in the root transition area between the first protruding plate 22 and the first side plate 2 it connects to, and in the root transition area between the second protruding plate 32 and the second side plate 3 it connects to. This fully utilizes the relatively concentrated material and high structural strength of this area. When adjacent modules are connected by mortise and tenon joints, the root of the slot 6 can more effectively bear and transfer the load from the tenon 5, reducing stress concentration at the connection point, thereby improving the overall stability and deformation resistance of the module splicing.

[0030] The top plate 4a and the bottom plate 4b are fixed to the top and bottom of the main frame respectively by metal connectors 7, forming a box, the interior of which serves as a place for the cat to rest and move around. Figure 3 As shown, the metal connector 7 consists of three mutually perpendicular connecting plates: a first connecting plate 71, a second connecting plate 72, and a third connecting plate 73. The first connecting plate 71 is connected to the inner side of the first side plate 2 and secured with screws; the second connecting plate 72 is connected to the inner side of the second side plate 3 and secured with screws; and the third connecting plate 73 is connected to the top plate 4a or the bottom plate 4b and secured with screws. The metal connector 7 is evenly distributed along the four corners of the top plate 4a or the bottom plate 4b.

[0031] The first side panel 2 has multiple scratch holes 21 extending through its thickness for the cat to scratch. In this embodiment, the scratch holes 21 are arranged in four rows horizontally. From top to bottom, the first and third rows of scratch holes 21 form an inverted Y-shape, while the second and fourth rows form an upright Y-shape. The Y-shaped structure provides multi-directional scratching paths (such as vertical and diagonal branches), which better matches the natural movement trajectory and force direction of the cat's paws when scratching, and can more effectively meet its scratching and extension needs, improving user comfort and scratching efficiency. The alternating arrangement of upright and inverted Y-shapes can create rich visual and tactile variations, stimulating the cat's interest in exploring and scratching, and helping to guide its scratching behavior to focus on a preset area, reducing damage to other parts of the home.

[0032] The second side panel 3 has a doorway 31 extending through its thickness for entry and exit. In this embodiment, the doorway 31 is rectangular.

[0033] The top plate 4a and bottom plate 4b are provided with climbing holes 41 extending through their thickness, allowing cats to pass vertically. In this embodiment, the climbing holes 41 are regular hexagons with rounded corners. Furthermore, adjacent climbing holes 41 are staggered. The symmetrical shape of the regular hexagon better matches the natural gripping form of a cat's paws, providing multiple points of leverage, facilitating stable and smooth vertical climbing and passage for the cat in different postures, enhancing comfort and convenience. The staggered arrangement of adjacent climbing holes 41 forms non-aligned vertical channels, creating a three-dimensional, interwoven network of passageways. This layout provides natural visual guidance and rhythmic variation for the cat's climbing path, better aligning with its exploratory nature and increasing the enjoyment of use.

[0034] When in use, a pad or soft mat can be placed on the upper surface of the top plate 4a or the bottom plate 4b to block the climbing hole 41 for the cat to rest.

[0035] Compared with the existing technology, the advantage of this embodiment is that it integrates the functions of cat bed, cat tree and scratching post into the same basic unit module 1. Through the setting of scratch hole 21, doorway 31 and climbing hole 41, it simultaneously meets the complex needs of cats such as rest, activity, scratching and vertical passage, realizes the natural connection of "rest-activity" scene and improves space utilization efficiency.

[0036] Example 2: like Figure 4 As shown, the present invention discloses a composite cat climbing frame, which is composed of three basic unit modules 1 stacked vertically. Its specific installation structure is as follows: the first side plate 2 and the second side plate 3 are provided with tenons 5 and slots 6 at the upper and lower ends of the vertical direction. Adjacent basic unit modules 1 can be connected in the vertical direction through tenon and slot slots to realize vertical stacking expansion.

[0037] The upper end of the first protruding plate 22 is flush with the upper end of the first side plate 2, and its lower end is spaced from the lower end of the second side plate 3; the lower end of the second protruding plate 32 is flush with the lower end of the second side plate 3, and its upper end is spaced from the upper end of the third side plate. With sufficient depth of the slot 6, the lower end of the upper first side plate 2 is fitted with the upper end of the lower first side plate 2; the lower end of the upper second side plate 3 is fitted with the upper end of the lower second side plate 3. During vertical splicing, the first side plate 2 and the second side plate 3 are directly fitted in the vertical direction, forming continuous panel contact. This design ensures tight contact between the edges of the side plates of adjacent modules, avoiding misalignment or gaps at the splicing points, thus guaranteeing the verticality and stability of the overall structure and preventing swaying or tilting due to uneven stress. The direct fitting of the side plates increases the contact area between modules, allowing vertical loads to be evenly transferred to the lower module through the panel surface, improving the overall load-bearing capacity and torsional strength, and extending service life.

[0038] The advantages of this design are: 1. The basic unit module 1 adopts a standardized cuboid box structure, which can be stacked and expanded vertically through mortise and tenon joints, or horizontally through horizontal abutment. Users can freely choose to combine one or more units according to the actual space size, apartment layout, or number of cats, forming diverse shapes and size adaptations, breaking through the space limitations of traditional fixed structures. 2. The modules are quickly assembled through the cooperation of tenons 5 and slots 6, without the need for additional tools or complex fixings; the overall structure is reinforced by the metal connectors 7 of the top plate 4a and the bottom plate 4b, ensuring the overall stability after stacking or juxtaposition, and can be placed directly on a flat surface without the need for wall or floor fixing, facilitating movement and rearrangement. 3. The modular design allows users to flexibly adjust the product size and form according to the living environment, adapting to single-unit use in small spaces, or expanding through multiple units to meet the needs of large spaces or multi-cat families, effectively avoiding the problems of duplicate purchases and space clutter caused by functional separation and fixed size. 4. All basic unit modules 1 have a unified structure, and the panels can be produced through standardized processes. The tenon and mortise connection method simplifies the manufacturing and assembly process, which is conducive to large-scale production and cost control.

[0039] Example 3: like Figure 5 As shown, the present invention discloses a composite cat climbing frame, which is formed by three rows of basic unit modules 1 radially abutting each other; the first row is provided with two vertically stacked basic unit modules 1; the second row is provided with three vertically stacked basic unit modules 1; and the third row is provided with one basic unit module 1.

[0040] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
