Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims benefit from currently pending U.S. Provisional Application No. 63/574,409 titled “Tine Replacement Device for a Muck Rake” and having a filing date of Apr. 4, 2024, all of which is incorporated by reference herein.

FIELD OF THE INVENTION

The present invention pertains generally to the field of agriculture tools, and more specifically to a device designed for the repair of muck rakes with broken tines.

BACKGROUND OF THE INVENTION

The term “muck rake” refers to a tool used for raking or gathering up debris, manure, or other undesirable substances, often found in agricultural or stable settings. Rakes have been used for centuries across different cultures for agricultural purposes. Muck rakes typically have sturdy tines and a broad head that are effective at gathering and moving muck, manure and other debris. Muck rakes have been a stable tool on the farm and in stable for cleaning animal enclosures, such as barns, stables, and coops, as well as managing compost piles and spreading manure as fertilizer on fields.

Early iterations of the muck rake were rudimentary, typically consisting of wooden handles affixed to metal prongs or tines. These implements were primarily used for gathering and removing animal waste, agricultural debris, and other undesirable materials from barns, stables, and fields. The design and functionality of these early muck rakes were rudimentary but effective, reflecting the agricultural practices and technological capabilities of their time. As agricultural practices progressed and industrialization took hold, muck rakes underwent refinements and improvements to meet the evolving needs of farmers, stable owners, and agricultural workers. Advancements in materials, such as the introduction of durable metals and synthetic polymers, led to the development of more robust and long-lasting muck rake designs.

However, muck rakes are still prone to wear and tear due to their frequent interaction with rough materials and surfaces. Over time, the tines of these rakes can break or become damaged, rendering the tool less effective or even unusable. Traditional methods of repairing these tools often involve replacing the entire rake, which can be costly and wasteful.

Therefore, there is a need for a device that allows the user to add tines onto a muck rake making it usable again without the costly replacement of the entire rake.

SUMMARY OF THE INVENTION

The present invention provides a tine replacement device for a muck rake with one or more broken tines. The device comprises at least one tine extending from a body, wherein the body includes at least one slot and at least one support prong. The device also includes at least one rake connection coupled to the support prong, and a first and second tine hole coupled to the body. The first tine hole is coupled to a first tine of the muck rake and the second tine hole is coupled to a second tine of the muck rake.

The tine has a substantially elongated body portion having a proximal end and a distal end. The tine can be integral to the body. The support prong extends from the body and engages a rake head. The support prong can comprise a rake connection hole wherein the rake connection can be removably coupled to the rake connection hole and the rake. The body, the tine, and the support prong can be formed from a durable and resilient material, such as metal, plastic, or composite material. The rake connection can be coupled to the rake head. The rake connection can be a zip tie, clamp, cable tie or hook and look ties.

The first tine hole and second tine hole can be positioned at an angle relative to each other to accommodate varying tine spacings on different muck rake models. The body further can further comprise a reinforcement rib extending between the first tine hole and the second tine hole to distribute force during use. The material can be specifically formulated to resist corrosion from animal waste and cleaning chemicals. The at least one tine can comprise a textured surface to enhance debris collection and retention. The body can comprise an adjustment mechanism allowing for variable positioning of the at least one tine relative to the muck rake head. The at least one tine can have a cross-sectional profile that transitions from a first shape at the proximal end to a second shape at the distal end to optimize both strength and debris collection. The body can further comprise at least one visual alignment guide to facilitate proper installation orientation relative to the muck rake head.

Furthermore, it is an objective and advantage of the present invention to provide a method of replacing damaged or worn tines on a muck rake. This method involves removing the damaged tines, sliding the tine replacement device over the remaining tines, and securing the device in place. This process is designed to be simple and straightforward, allowing even those with limited technical skills to perform the replacement. Finally, it is an objective and advantage of the present invention to provide a tine replacement device that can be periodically inspected and maintained to ensure optimal performance and longevity of the muck rake assembly. This promotes the sustainable use of the tool, further contributing to cost savings and environmental conservation. The tine replacement device for a muck rake provides a simple and effective solution for replacing broken tines on a muck rake, enhancing its durability and functionality.

It is an object of the invention to replace the broken tines of a muck rake without replacing the whole rake.

Referring to FIGS. 1-6 a tine replacement device for a muck rake with one or more broken tines is shown generally at 10. The tine replacement device for a muck rake 10 can comprise at least one tine 12 extending from a body 20. The at least one tine 12 can have a substantially elongated body having a proximal end 14 and a distal end 16 wherein the distal end can come to a such as, for example, blunt end, pointed end, rounded end, chiseled end, tapered end, or the like. The at least one tine 12 can be such as for example, one tine, two tines, three tines, four tines, five tines, or the like each evenly or unevenly spaced between each other. The at least one tine 12 can have a thickness substantially the same or similar as the muck rake tines. The at least one tine 12 can substantially narrow in thickness from the proximal end 14 to the distal end 16. The tine replacement device 10 can fit or change size and shape to fit various manufacturer's muck rake designs.

In certain embodiments, the body 20 can include a variable-pitch mounting system 22 capable of adjusting the tine angulation relative to the rake handle within a range of 10 to 45 degrees to optimize collection efficiency across different substrate densities. Each tine 12 can have a composite construction featuring a flexible elastomeric core 24 encased within a rigid outer shell 26, allowing for enhanced debris release through controlled flexion while maintaining structural integrity during operation. The proximal end 14 of each tine 12 can include an integrated wear indicator 28 comprising a visually distinct material that becomes exposed when the tine reaches a predetermined wear threshold, thereby signaling replacement necessity without requiring manual measurement. The body 20 can comprise a modular connection interface 30 compatible with multiple rake handle configurations, eliminating the need for specialized adapters when transferring the replacement device between different rake models.

In embodiments, the body 20 can be integral to the at least one tine 12 or the at least one tine can be coupled to the body by such as, for example, fastener, rivet, adhesive, screw, or the like allowing the user to replace the tines if broken. The body 20 can have at least one support prong 24 extending from the opposite of the body as the at least one tine 12. The at least one support prong 24 can have the substantially the same thickness, a larger or a smaller thickness as the body 20. The at least one support prong 24 can be integral to the body and can have a thickness and a support end 25 wherein the support end can engage a muck rake head which can support the tine replacement device 10 against the muck rake head. In other embodiments, the support prong 24 and at least one tine 12 can be any suitable shape and size as shown in FIG. 9 and FIG. 10. The support prong 12 can have angle portion at the top portion or bottom portion depending on the muck rake it is being attached to. The at least one tine 12 can match the tines of the muck rake it is being attached to as shown in FIG. 9 and FIG. 10.

In certain embodiments, the at least one support prong 24 can incorporate a self-aligning orientation mechanism 26 comprising magnetic elements calibrated to automatically position the tine replacement device 10 in optimal alignment with the muck rake head upon installation. The body 20 can feature a progressive load distribution network 28 comprising a series of variably-sized internal chambers 30 that redistribute impact forces encountered during operation, substantially reducing stress concentration at connection points between the body 20 and the muck rake head. Additionally, the body 20 can include an integrated debris-shedding surface treatment consisting of microscopic hydrophobic patterns that actively repel adherent organic matter during use, thereby maintaining consistent weight and performance characteristics throughout operation. The support prong 24 can further include an adjustable engagement depth limiter 34 that allows the user to customize the insertion profile according to specific muck rake head geometries, ensuring maximum stability across various manufacturer designs without requiring specialized tools or modifications.

In embodiments, the support end 25 can have a rake connection hole 26 wherein a rake connection can be removably coupled to the rake connection hole. The rake connection can be such as for example, zip ties, cable ties, clamps, nylon straps, hook and look fastener, cables, or the like.

In embodiments, the body 20 can further comprise at least one tine hole wherein in FIG. 1 shows a first tine hole 22 and second tine hole 32 coupled to or integrated with the body. The first tine hole 22 can be coupled to a first tine of the muck rake and the second tine hole 32 can be coupled to a second tine of the muck rake. In other embodiments, the at least one tine hole can be such as, for example, one, two, three, four, five, six or the like. The tine holes 22, 32 can be the substantially the same shape as the rake tine allowing for a loose fit, press fit, or interference fit of the tine holes and the muck rake tines.

In certain embodiments, the tine holes 22, 32 can comprise a multi-phase engagement system featuring graduated inner diameters that progressively constrict upon installation, transitioning from an initially generous clearance to a precision-fit final position without requiring additional fastening components. The inner surface of each tine hole 22, 32 can include a series of micro-channeled retention ridges arranged in a helical pattern, creating directional resistance that facilitates easy installation while significantly increasing removal force, thereby preventing unintended detachment during operation. The body 20 can further comprise an integrated tine position indexing system wherein each tine hole 22, 32 incorporates position-specific material density variations that correspond to optimal placement locations on the muck rake head, providing tactile feedback during installation when proper alignment is achieved.

In embodiments, the body 20, the tines 12, and the support prong 24 can be formed from a durable and resilient material, such as, for example, metal, plastic, ceramic, composite material, or the like. The material can be optimized for specific operational environments, with high-density polyethylene (HDPE) providing superior performance in wet conditions, aircraft-grade aluminum alloys offering enhanced strength-to-weight ratios for extended use, and glass-reinforced nylon compounds delivering exceptional impact resistance during heavy-duty applications. The material composition can further incorporate UV-stabilizing additives to prevent degradation during prolonged outdoor exposure, while strategic reinforcement zones at high-stress junction points can significantly extend operational lifespan. The tine replacement device 10 can provide a simple and effective solution for replacing broken tines on a muck rake, enhancing its durability and longevity while eliminating the need for complete rake replacement. This modular approach supports sustainable maintenance practices by reducing material waste and extending the functional lifespan of existing equipment, thereby offering both economic and environmental advantages over conventional rake replacement methods.
