Description

[Technical Field] This application belongs to the technical field of lawn rakes, specifically relating to a labor-saving horizontal lawn rake. [Background Technology] In lawn maintenance, the lawn rake is a commonly used tool for trimming lawns and leveling soil. Most existing lawn rakes have a straight edge design on the pushing side of the rake frame. When the user pushes the rake on the lawn, the contact method between the straight edge and the ground results in greater resistance, requiring the user to apply considerable force to move the rake forward. This is especially true when dealing with dense lawns or compacted soil, significantly increasing the user's workload and fatigue, reducing work efficiency, and limiting the widespread application of lawn rakes in scenarios where ease of operation is crucial. [Utility Model Content] To address the problems of high pushing resistance and laborious operation of existing lawn horizontal rakes, this application provides a labor-saving lawn horizontal rake.

[0001] This application is achieved through the following technical solution: A labor-saving horizontal lawn rake includes a rake frame, a first rod disposed within the rake frame and connecting the left and right sides of the rake frame, and a second rod and a third rod disposed on the first rod and connecting the front and rear sides of the rake frame and spaced apart from each other. One side of the rake frame includes at least one set of inclined sides, the set of inclined sides including a first inclined side and a second inclined side that intersects with the first inclined side to form an angle.

[0002] As described above, in a labor-saving lawn rake, the first inclined side and the second inclined side intersect on the side of the rake frame in the forward direction to form the included angle; or the first inclined side and the second inclined side intersect on the side of the rake frame in the backward direction to form the included angle.

[0003] As described above, in a labor-saving lawn rake, the first inclined side and the second inclined side meet on one side of the rake frame in the forward direction to form an angle that protrudes outward from the rake frame; or the first inclined side and the second inclined side meet on one side of the rake frame in the forward direction to form an angle that is concave inward from the rake frame.

[0004] As described above, in a labor-saving lawn rake, the first inclined side and the second inclined side meet on the side of the rake frame in the backward direction to form an angle that protrudes outward from the rake frame; or the first inclined side and the second inclined side meet on the side of the rake frame in the backward direction to form an angle that is concave inward from the rake frame.

[0005] As described above, in a labor-saving horizontal lawn rake, the first inclined side and the second inclined side meet on the forward direction side of the rake frame to form an angle that protrudes outward from the rake frame; the first inclined side and the second inclined side meet on the backward direction side of the rake frame to form an angle that protrudes outward from the rake frame or is concave inward from the rake frame.

[0006] The labor-saving lawn rake described above also includes a push rod handle, and an installation space is formed between the second rod and the third rod for connecting the push rod handle.

[0007] In the above-described labor-saving lawn rake, the outer contour of the first rod corresponds to the inclined side assembly.

[0008] As described above, in a labor-saving lawn rake, one end of the push rod handle is connected to a hinge, the hinge has a first connecting hole, the second rod and the third rod have a second connecting hole and a third connecting hole respectively, and a fastener passes through the first connecting hole, the second connecting hole and the third connecting hole to hinge the push rod handle to the rake frame.

[0009] As described above, a labor-saving horizontal lawn rake has an L-shaped cross-section for its frame.

[0010] As described above, a labor-saving horizontal lawn rake has two sets of inclined sides on the forward and backward sides of the rake frame.

[0011] Compared with the prior art, this application has the following advantages: This application discloses a labor-saving lawn rake. It features at least one set of inclined sides on one side of the rake frame, including a first and a second inclined side intersecting at an angle. When the rake is pushed, this inclined side design allows it to cut into the lawn soil or grass roots at an angle, effectively dispersing and reducing frontal resistance, thus significantly reducing the required pushing force and improving labor-saving operation. Simultaneously, the structure of the first rod connecting the left and right sides of the rake frame, and the second and third rods spaced apart and connecting the front and rear sides of the rake frame, enhances the stability and rigidity of the overall frame. This ensures that the inclined side set distributes the load evenly when under stress, preventing deformation or jamming, further improving the efficiency of leveling operations and extending the tool's service life. [Attached Image Description] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

Detailed Implementation Methods

[0013] Please see Figures 1 to 11 A labor-saving lawn rake includes a rake frame 1, a first rod 2 disposed inside the rake frame 1 and connecting the left and right sides of the rake frame 1, and a second rod 3 and a third rod 4 disposed on the first rod 2 and connecting the front and rear sides of the rake frame 1 and spaced apart from each other. One side of the rake frame 1 includes at least one inclined side group 5, the inclined side group 5 including a first inclined side 51 and a second inclined side 53 that intersects with the first inclined side 51 to form an angle 52.

[0014] This application discloses a labor-saving lawn rake. It utilizes at least one set of inclined sides on one side of the rake frame, including a first and a second inclined side intersecting at an angle. When the rake is pushed, this inclined side design allows it to cut into the lawn soil or grass roots at an angle, effectively dispersing and reducing frontal resistance, thereby significantly reducing the required pushing force and improving labor-saving operation. Simultaneously, the structure of the first rod connecting the left and right sides of the rake frame, and the second and third rods spaced apart and connecting the front and rear sides of the rake frame, enhances the stability and rigidity of the overall frame, ensuring that the inclined side group evenly transmits the load when under stress, avoiding deformation or jamming, further improving the efficiency of leveling operations and extending the tool's service life. The first rod can be a solid square tube or a grooved square tube, and the second and third rods can also be solid square tubes or grooved square tubes.

[0015] Furthermore, as a preferred embodiment of this solution and not a limitation, the first inclined side 51 and the second inclined side 53 intersect on the side of the rake frame 1 in the forward direction to form the included angle 52; or the first inclined side 51 and the second inclined side 53 intersect on the side of the rake frame 1 in the backward direction to form the included angle 52.

[0016] In this embodiment, when the first inclined side 51 and the second inclined side 53 are located on the forward direction side, they cut into the soil at an inclined angle, effectively dispersing and reducing frontal resistance. This significantly reduces the pushing force required by the operator when pushing the lawn rake horizontally, thereby improving the labor-saving aspect of the operation. It is particularly suitable for areas with high soil moisture, effectively overcoming the high resistance problem caused by traditional straight-edge designs. If the first inclined side 51 and the second inclined side 53 are located on the backward direction side, they can play the same role during the backward pulling process, further enhancing the flexibility and efficiency of the operation. This bidirectional design is not only suitable for conventional forward pushing operations but also provides convenience for backward tidying, allowing users to choose a more suitable operating direction according to actual operational needs, thereby improving overall operational efficiency.

[0017] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the first inclined side 51 and the second inclined side 53 meet on one side of the rake frame 1 in the forward direction to form the included angle 52 that protrudes outward from the rake frame 1; or the first inclined side 51 and the second inclined side 53 meet on one side of the rake frame 1 in the forward direction to form the included angle 52 that is concave in the rake frame 1.

[0018] In this embodiment, when the first inclined side 51 and the second inclined side 53 are located on one side of the rake frame 1 in the forward direction and form an outwardly convex angle 52, the labor-saving performance of the lawn horizontal rake can be significantly improved. The outwardly convex angle cuts into the soil with a smoother curve during the pushing process, effectively dispersing the frontal resistance and reducing the pushing force required by the operator, especially when dealing with lawn soil with high moisture content. This smooth transition not only reduces the instantaneous resistance peak but also reduces the direct impact on the grass roots. On the other hand, if the angle 52 is designed as a concave structure, it can provide better maneuverability and directional stability during the pushing process. The concave design helps to reduce jamming when turning or adjusting direction, making the operation more flexible and smooth, and improving the overall work efficiency and user experience.

[0019] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the first inclined side 51 and the second inclined side 53 meet on the side of the rake frame 1 in the backward direction to form the included angle 52 that protrudes outward from the rake frame 1; or the first inclined side 51 and the second inclined side 53 meet on the side of the rake frame 1 in the backward direction to form the included angle 52 that is concave in the rake frame 1.

[0020] In this embodiment, when the first inclined side 51 and the second inclined side 53 are located on the backward direction side of the rake frame 1 and form an outwardly convex angle 52, it provides a significant labor-saving advantage for the backward pulling operation of the lawn horizontal rake. The outwardly convex angle structure cuts into the soil with a smooth curve during the backward movement, effectively dispersing the resistance during the backward movement and greatly reducing the pulling force required by the operator when performing backward trimming. This is especially important for scenarios that require frequent backward movements, such as working in narrow areas or complex terrain. The smooth curve design not only reduces the peak pulling force but also reduces potential damage to the lawn, helping to maintain the health of the lawn. If the angle 52 is designed as a concave structure, it can provide better directional control and stability during the backward movement. The concave design helps to reduce jamming and friction when turning or adjusting direction during backward movement, making the operation more flexible and precise. This can significantly improve work efficiency and effectiveness in situations that require fine adjustment of the working direction, such as edge treatment or local trimming.

[0021] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the first inclined side 51 and the second inclined side 53 intersect on the forward direction side of the rake frame 1 to form the included angle 52 that protrudes outward from the rake frame 1; the first inclined side 51 and the second inclined side 53 intersect on the backward direction side of the rake frame 1 to form the included angle 52 that protrudes outward from the rake frame 1 or is concave inward from the rake frame 1.

[0022] In this embodiment, this bidirectional optimization design not only meets the different needs of forward and backward operations, but also significantly improves the overall performance and applicability of the tool, enabling more efficient and flexible lawn maintenance operations.

[0023] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a push rod handle 6, wherein an installation space 7 is formed between the second rod 3 and the third rod 4 for connecting the push rod handle 6.

[0024] In this embodiment, the installation space 7 allows the push rod handle 6 to be securely connected to the middle of the rake frame 1, providing a good torque balance point. This allows the user to apply force more evenly when pushing or pulling the rake, thereby reducing physical exertion and improving operational comfort. This structural design effectively avoids the operational difficulties and instability caused by unreasonable handle placement in traditional designs. By installing the push rod handle 6 in the installation space 7 between the second rod 3 and the third rod 4, the stability and rigidity of the overall frame are enhanced, ensuring the stability of the push rod handle 6 under load. Furthermore, by evenly distributing the load, the risk of deformation of the rake frame 1 is reduced, extending the tool's service life.

[0025] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer contour of the first rod 2 corresponds to the inclined side group 5.

[0026] In this embodiment, the close structural fit and coordination between the first rod 2 and the inclined side assembly 5 are ensured, enhancing the stability and rigidity of the overall frame. Since the inclined side assembly 5 experiences significant stress during pushing and pulling, the corresponding contour of the first rod 2 effectively disperses and transmits this stress, reducing local stress concentration and thus lowering the risk of deformation of the rake frame 1 and extending the tool's service life.

[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, one end of the push rod handle 6 is connected to a hinge member 8, the hinge member 8 is provided with a first connecting hole 81, the second rod member 3 and the third rod member 4 are respectively provided with a second connecting hole 31 and a third connecting hole 41, and a fastener passes through the first connecting hole 81, the second connecting hole 31 and the third connecting hole 41 to hinge the push rod handle 6 to the rake frame 1.

[0028] In this embodiment, the hinged connection allows the push rod handle 6 to rotate flexibly relative to the rake frame 1, thereby adjusting the operating angle and direction. This flexibility not only improves operational comfort but also allows users to select the most suitable handle position according to actual work needs, reducing hand fatigue caused by prolonged work. By adjusting the handle angle, users can more easily cope with different terrains and working environments, improving work efficiency. Fasteners include bolts or screws.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the cross-section of the frame 1 is L-shaped.

[0030] In this embodiment, while minimizing weight, the L-shaped cross-section enhances the rigidity and stability of the rake frame 1. This effectively resists stress and pressure during operation, reducing the risk of deformation and thus extending the tool's service life. This design is particularly suitable for scenarios requiring heavy loads or operation in complex terrain, ensuring the tool's reliability and durability in various environments.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the forward and backward sides of the rake frame 1 include two inclined side groups 5.

[0032] In this embodiment, the four beveled edge groups 5 enhance the overall stability and rigidity of the rake frame 1. Since the beveled edge groups 5 bear significant stress during operation, increasing the number of beveled edge groups allows for a more even distribution of this stress, reducing localized stress concentration and thus lowering the risk of deformation of the rake frame 1, extending the tool's service life. This design is particularly suitable for scenarios requiring frequent bidirectional operations or operation in complex terrain, ensuring the tool's reliability and durability in various environments.

[0033] In this first embodiment, as Figure 4 As shown, the first inclined side 51 and the second inclined side 53 intersect on the forward direction side of the rake frame 1 to form an angle 52 that protrudes outward from the rake frame 1; and the first inclined side 51 and the second inclined side 53 intersect on the backward direction side of the rake frame 1 to form an angle 52 that is concave inward from the rake frame 1, with the angle on the forward direction side being smaller than the angle on the backward direction side.

[0034] In this second embodiment, as Figure 5 As shown, the first inclined side 51 and the second inclined side 53 intersect on one side of the rake frame 1 in the forward direction to form the included angle 52 that protrudes outward from the rake frame 1.

[0035] In this third embodiment, as Figure 6 As shown, the first inclined side 51 and the second inclined side 53 meet on the side of the rake frame 1 in the backward direction to form the included angle 52 that is concave to the rake frame 1.

[0036] In this fourth embodiment, as Figure 7 As shown, the two inclined sides 5 are located on one side of the rake frame 1 in the forward direction and intersect to form two included angles 52 that protrude outward from the rake frame 1.

[0037] In this fifth embodiment, as Figure 8As shown, the two inclined sides 5 meet on the forward direction side of the rake frame 1 to form two included angles 52 that bulge outward from the rake frame 1; and the two inclined sides 5 meet on the backward direction side of the rake frame 1 to form two included angles 52 that are concave inward from the rake frame 1.

[0038] This is Example 6, as follows Figure 9 As shown, the two inclined sides 5 are located on one side of the rake frame 1 in the forward direction and intersect to form two included angles 52 that are concave in the rake frame 1.

[0039] This is Example 7, as follows Figure 10 As shown, the first inclined side 51 and the second inclined side 53 intersect on the side of the rake frame 1 in the forward direction to form an included angle 52 that protrudes outward from the rake frame 1; and the first inclined side 51 and the second inclined side 53 intersect on the side of the rake frame 1 in the backward direction to form an included angle 52 that protrudes outward from the rake frame 1.

[0040] This is Example 8, as follows Figure 11 As shown, the two inclined sides 5 meet on the forward direction side of the rake frame 1 to form two included angles 52 that protrude outward from the rake frame 1; and the two inclined sides 5 meet on the backward direction side of the rake frame 1 to form two included angles 52 that protrude outward from the rake frame 1.

[0041] The working principle of this embodiment is as follows: This application discloses a labor-saving lawn rake. It features at least one set of inclined sides on one side of the rake frame, including a first and a second inclined side intersecting at an angle. When the rake is pushed, this inclined side design allows it to cut into the lawn soil or grass roots at an angle, effectively dispersing and reducing frontal resistance, thus significantly reducing the required pushing force and improving labor-saving operation. Simultaneously, the structure of the first rod connecting the left and right sides of the rake frame, and the second and third rods spaced apart and connecting the front and rear sides of the rake frame, enhances the stability and rigidity of the overall frame. This ensures that the inclined side set distributes the load evenly when under stress, preventing deformation or jamming, further improving the efficiency of leveling operations and extending the tool's service life.
