Description

Technical Field

[0001] This application relates to the technical field of public facilities, and in particular to a park bench with adjustable length. Background Technology

[0002] Park benches are an important part of park public facilities, providing space for visitors to rest and chat. They are commonly found along walkways, under trees, and around plazas, and are mainly made of anti-corrosion wood, metal, and composite plastics.

[0003] Park benches are a key facility for enhancing the user experience and comfort of parks, and their design must balance practicality with harmony with the overall park landscape. However, most existing park benches are of fixed sizes, exhibiting significant limitations in adaptability. Due to substantial differences in space across different areas of a park—for example, a narrow path can only accommodate a 1.2-meter-long double bench, while an open plaza or rest platform can accommodate benches longer than 2 meters—park management often needs to customize benches of different lengths for each area to meet the diverse needs. This customization not only increases production and procurement costs (different sizes require separate molds and processing, failing to achieve the cost advantages of mass production), but also results in inconsistent bench specifications, a less aesthetically pleasing appearance, and disruption of the park's overall landscape. Furthermore, subsequent maintenance requires stocking spare parts for different sizes, further increasing management costs. Utility Model Content

[0004] To address the issue of needing to install park benches in different locations, which increases costs and is aesthetically unappealing, this application provides a park bench with an adjustable length.

[0005] This application provides an adjustable-length park bench, which adopts the following technical solution: An adjustable-length park bench includes a first bench body and a second bench body, which are arranged opposite each other in the length direction. The first bench body has a tenon on the side near the second bench body, and the second bench body has a protrusion on the side near the first bench body. The protrusion forms a mortise that matches the tenon. The tenon and the mortise overlap to form a riveting part. The first bench body and the second bench body are slidably connected through the riveting part, and the protrusion supports the tenon.

[0006] By adopting the above technical solution, the mortise and tenon connection between the first and second benches enables the park benches to have an adjustable length, making them suitable for various spaces. In large spaces with high traffic, the first and second benches can be spaced further apart to increase the bench's length and accommodate more people. In confined spaces, the first and second benches can be brought closer together to reduce the bench's length. This solution unifies the style of benches throughout the park, eliminating the need for custom-made benches of different sizes, allowing for mass production, reducing construction costs, and making the park more aesthetically pleasing and harmonious. In this technical solution, when the first and second benches are spaced further apart, some tenons are exposed, allowing people to sit on them. Simultaneously, the protrusions support the tenons, effectively preventing them from breaking under pressure.

[0007] Preferably, the tenon includes a central protrusion disposed at the end of the first stool body, the central protrusion being disposed at the center position in the vertical direction of the first stool body, and two protrusions disposed at the end of the second stool body, the two protrusions being disposed on the upper and lower sides of the second stool body respectively, the central protrusion and the protrusions being disposed along the length direction of the first stool body, and the two protrusions forming a central groove for accommodating the central protrusion, the lower protrusion supporting the central protrusion.

[0008] By adopting the above technical solution, the tenon is just a central protrusion. The central protrusion is stuck in the central groove. The protrusion can only provide vertical constraint to the central protrusion. The central protrusion has no horizontal support. Therefore, the first stool body and the second stool body can be deflected at a certain angle in the horizontal direction, which can adapt to more usage scenarios.

[0009] Preferably, the upper and lower surfaces of the central protrusion are provided with vertical protrusions, the vertical protrusions are arranged along the length direction of the first stool body, and the protrusions are provided with vertical grooves that match the size of the vertical protrusions, the vertical protrusions are engaged in the vertical grooves.

[0010] By adopting the above technical solution, the interaction between the vertical protrusion and the vertical groove can limit the mutual rotation between the first stool and the second stool, making the first stool and the second stool more stable and less prone to shaking.

[0011] Preferably, both the first stool and the second stool are provided with support legs at their bottoms.

[0012] By adopting the above technical solution, the support legs can support the first and second stool bodies and play a role in moisture prevention.

[0013] Preferably, the supporting leg is an isosceles trapezoidal upright support.

[0014] By adopting the above technical solution, the lower base of the trapezoid is supported on the ground, and the upper base is supported on the bottom of the bench, making the support more stable.

[0015] Preferably, the first stool body and the second stool body are cuboids of the same shape, and the tenon is integrally formed with the first stool body, and the protrusion is integrally formed with the second stool body.

[0016] By adopting the above technical solutions, mass production and processing can be facilitated, and production efficiency can be improved.

[0017] Preferably, the contact surfaces of the tenon and the protrusion are provided with anti-slip parts.

[0018] By adopting the above technical solution, sliding between the first stool and the second stool is prevented.

[0019] Preferably, a stop is provided at the end of the tenon away from the first stool body, and when the first stool body and the second stool body approach each other, the stop abuts against the end of the second stool body.

[0020] By adopting the above technical solution, personnel can be protected and prevented from being pinched or injured when the first and second benches are close together.

[0021] Preferably, the upper surface of the tenon is provided with a downward-sloping water-guiding gradient.

[0022] By adopting the above technical solution, rainwater can be drained away through a gradient, preventing water accumulation on the tenon.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The first and second bench bodies, connected by mortise and tenon joints, allow for adjustment of the park bench length, increasing the applicability of the park bench, reducing production costs, enhancing the uniformity of the park landscape, and making it more aesthetically pleasing; 2. A stop is provided between the first and second stools to prevent people from being pinched when the first and second stools come close together. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail.

[0027] This application discloses an adjustable-length park bench.

[0028] Reference Figure 1 and 2 An adjustable-length park bench includes a first bench body 1 and a second bench body 2, both of which are cuboids of the same size. To enhance aesthetics, their surfaces are painted in different colors. The first bench body 1 and the second bench body 2 are positioned opposite each other along their length. A tenon 11 is located on the side of the first bench body 1 closest to the second bench body 2, and a protrusion 22 is located on the side of the second bench body 2 closest to the first bench body 1. The protrusion 22 forms a mortise 21 that matches the size of the tenon 11. The tenon 11 is inserted into the mortise 21, and the tenon 11 and mortise 21 overlap to form a riveting joint. The first bench body 1 and the second bench body 2 are slidably connected through this riveting joint. For a more aesthetically pleasing design, the length of the tenon 11 should be half that of the first bench body 1, and the length of the protrusion 22 should be the same as the length of the tenon 11. Furthermore, the tenon 11 and the first bench body 1 are integrally formed, and the protrusion 22 and the second bench body 2 are integrally formed. The width of tenon 11 is the same as that of the first bench body 1, and the width of protrusion 22 is the same as that of the second bench body 2. When the first bench body 1 and the second bench body 2 are far apart, the overlap between tenon 11 and mortise 21 decreases, increasing the overall length of the bench. A significant portion of tenon 11 is exposed, allowing visitors to sit on it. When space is limited, the first bench body 1 and the second bench body 2 can be brought closer together, increasing the overlap between tenon 11 and mortise 21 and decreasing the overall length of the bench. This design allows for adjustable bench length, eliminating the need for custom-made benches for different spaces, thus saving costs. Furthermore, the consistent style of the benches enhances the overall aesthetics of the park.

[0029] Reference Figure 1 and 2The tenon 11 includes a central protrusion 111 located at the end of the first stool body 1, positioned at the center of the stool body 1 in the vertical direction. The mortise 21 includes a central groove 211 matching the central protrusion 111, with the bottom surface of the central groove 211 supporting the central protrusion 111. The tenon 11 also includes a vertical protrusion 112 on the upper surface of the central protrusion 111, arranged along the length of the first stool body 1. The height of the upper surface of the vertical protrusion 112 is flush with the upper surface of the first stool body 1. The mortise 21 includes a vertical groove 212 matching the size of the vertical protrusion 112, with the vertical protrusion 112 engaged within the vertical groove 212. The lower surface of the central protrusion 111 also has the same vertical protrusion 112. The central protrusion 111 and the two vertical protrusions 112 combine to form a cross-shaped tenon 11, with the shape of the mortise 21 matching the shape of the tenon 11. Visitors to the park can sit on the central protrusion 111 and lean against the vertical protrusion 112, a design that makes sitting more comfortable. The vertical protrusion 112 also prevents the bench from wobbling, improving stability. In some embodiments, the bench needs to be installed on a curved path; therefore, the vertical protrusion 112 is designed as an arc extending from the first bench body 1. The first bench body 1 and the second bench body 2 can form an arc. Because the vertical protrusion 112 is curved, the first bench body 1 and the second bench body 2 can slide relative to each other along an inclined angle, adapting to the curved path.

[0030] Reference Figure 1 and 2 The contact surfaces of the central protrusion 111 and the protrusion 22 are provided with anti-slip parts 4. The anti-slip parts 4 have a frosted surface, which increases the friction between the central protrusion 111 and the protrusion 22, preventing the first stool body 1 and the second stool body 2 from easily sliding against each other. The bottom of the first stool body 1 and the second stool body 2 are each provided with two support legs 3. Taking the first stool body 1 as an example, the support leg 3 is an isosceles trapezoid, where the base of the support leg 3 is rectangular, and the long side of the rectangle is along the width direction of the first stool body 1, and the length of the long side is the same as the width of the first stool body 1. The two support legs 3 are respectively located at one end near the first overlapping part and the other end away from the first overlapping part. The bottom of the second stool body 2 is provided with support legs 3 of the same shape and corresponding position.

[0031] Reference Figure 2 and 3The upper surface of the central protrusion 111 has a downward-sloping water-draining slope 6 from the position of the vertical protrusion 112 towards both sides. The slope angle of the water-draining slope 6 is 2%. When rainwater falls on the tenon 11, it can slide down along the water-draining slope 6. A stop block 5 is provided at the end of the tenon 11. The stop block 5 is located at the center of the end of the tenon 11. When the first stool 1 and the second stool 2 approach each other, the stop block 5 abuts against the end of the mortise 21. The stop block 5 can block between the first stool 1 and the second stool 2, preventing the first stool 1 and the second stool 2 from completely fitting together and preventing hands from being pinched after the first stool 1 and the second stool 2 fit together.

[0032] The implementation principle of this application embodiment is as follows: the bench is composed of a first bench body 1 and a second bench body 2 connected by mortise and tenon joints, which allows the entire bench to be extended and shortened, and can be used in different scenes of the park. It does not require additional customization of benches of different sizes, and can achieve a unified visual effect, making the park more beautiful. The first bench body 1 and the second bench body 2 are connected by mortise and tenon joints, and the friction between the two is large, making it difficult for them to separate from each other, and they have sufficient support.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
