Description

Ergonomic labor-saving gardening tool grip

This creation relates to a hand tool, and more particularly to a hand tool device for gardening. The present tooling device includes a rotating handle that can be rotated over a 360 degree range to help reduce the risk of injury and to increase the force applied during gardening by creating a favorable angle between the entry of the hand tool into the ground point.

Gardening requires the use of a variety of tools, including hand tools or power tools. Hand tools are any of a number of tools for gardening and gardening and overlap with various tools for agriculture and gardening. Hand tools are often an ideal choice when power tools can be impractical or cumbersome to use. Hand tools are also generally preferred over other larger gardening tools because hand tools require only one hand, take up minimal space, and are easy to store.

The hand tools used by today's gardeners come from the earliest tools used by humans, such as hoes, pitchforks, forks, scorpions, manual tillers, shovel and hand trowels. The earliest tools were made of wood, flint, metal, tin and bone. However, the development of metal processing, first of all copper and later steel, allows the industry to manufacture more durable tools.

Unfortunately, the use of hand tools in gardening can result in strain damage (RSI) due to repeated work, strong action, vibration, mechanical compression, or repeated work movements. RSI It is damage to the musculoskeletal and nervous system that can affect any part of the body and sometimes in multiple locations such as, but not limited to, the neck, shoulders, elbows, hands, wrists and fingers. Repetitive stress injuries can develop over time and can lead to long-term disability.

According to the National Institute for Occupational Safety and Health (NIOSH), excessive force exerted on muscles may increase the likelihood of musculoskeletal injuries and disorders. In addition, NIOSH cites some research, pointing out that even if it is not excessive power, it may make a person vulnerable to musculoskeletal injuries and diseases, especially in repetitive activities or static activities in awkward postures.

Fortunately, several methods for reducing repetitive strain damage in horticulture have been developed today. Some of the most common methods include keeping the elbows partially curved, especially when performing resistance activities that require elbow strength; avoiding repeated twisting of the forearms; keeping the wrists in a neutral position; easily holding the object in a short period of time; Struggling on the ground. While these actions can help reduce the occurrence of repetitive stress injuries, in order to prevent repetitive strain damage, a suitable hand tool with a comfortable functional design is also required. In fact, ergonomic design is necessary to prevent repetitive strain injuries and other musculoskeletal disorders that develop over time and can lead to long-term disability.

Ergonomics is designed to design the best products, systems, or processes to achieve interaction with the people who use them. Ergonomics focuses on the "fitness" between users, equipment and their environment. The goal of ergonomics is to design a tool that reduces stress on the body. The ergonomic design of the equipment, systems and working methods enhances user comfort, health, safety and productivity.

Conventional hand tools are generally suitable for all sizes. For most occasional use For manual tool people, this approach may be sufficient. However, the inaccurate fit of hand tools to the shape and flexibility of the human hand can cause limited problems.

Some people in the population use hand tools daily as part of their hobbies or work, and for these people, the lack of manual tools to fully adapt to the human hand can cause serious physical harm. As a result, manufacturers have adopted ergonomically designed garden tools for those users who have physical limitations but still need to engage in gardening activities outdoors. Ergonomic hand tools are designed to keep your body in a neutral position while working, reducing stress on your joints and muscles. The ergonomic design incorporates hand tools for gardening, enabling landscapers to enjoy all the fun and productivity of gardening while reducing work energy.

In horticulture, ergonomic design not only reduces the risk of injury, but also helps with force applications. The ergonomic design of the hand tool allows the user to take the angle that best suits the job. For example, the handle of a hand tool must be held at an angle that is as small as possible relative to the ground in order to propel motion such as digging or lifting as efficiently as possible. If the angle between the handle and the ground becomes too large, the base of the hand tool will have less contact with the ground and adversely affect the desired operation. Essentially, effectively adjusting the angle between the handle and the ground allows the hand tool to apply pressure over a wider area, making operation more efficient and easier to perform.

Many hand tools are currently designed with cushion handles. Initially, the difference between buffered and unbuffered handles is subtle, but over time, the reduction in tension between the arms and arm muscles becomes more pronounced. However, the bumper handle itself is not sufficient to protect the user and meet all of the user's ergonomic requirements. In addition, simple buffering does not help or improve the power application of hand tools.

Therefore, a manual tool is needed to allow the user to increase the power as much as possible. Acting while providing the risk of minimal injury. Therefore, there is still a need for a hand tool that provides a more ergonomic design to improve user comfort, health, safety and productivity.

The purpose of this creation is to provide a novel tool grip that is compatible with a variety of gardening and hand tools, including but not limited to hoes, tweezers, shovel, forks, drills, weeding tools, and knives.

This creation is an ergonomic and labor-saving gardening tool. The designed rotary handle can be adjusted with a retractable locking mechanism within a 360 degree range to match the user's preferences and perform operations while reducing the risk of injury. And improve comfort and productivity. In one embodiment, the rotating hand held handle can be rotated 360 degrees. In another embodiment, the releasable locking mechanism allows the rotary handle to be rotated 45 degrees each time. In particular, the hand tool device provides a rotary handle that can be adjusted to the different needs of the user, which will result in less strain on the hand, wrist and arm. This is because the function of the hand is important for work efficiency, and the hand requires a certain degree of strength and precision, depending on the type of task performed. The correct combination of power and precision in processing tasks involves the delicate management of the opponent's sensory system. Thus, the present invention takes into account the anatomical and physiological characteristics of the hand by providing a rotating handle that can adjust the physical and physiological needs of the user based on the tasks the user is seeking to accomplish.

In particular, in the design of the segment-restricted rotation section, the surface of the male member has a spring-loaded tip and a plurality of recesses on the inner bottom surface of the female member. This combination of spring and recessed pins provides a more practical hand tool based on the user's grip.

However, for the non-segment limit rotation section, in order to prevent too much or too little rotation It is important to design a locking mechanism. The locking mechanism is generally pivotally coupled to the coupling of the rotary handle and the connector and is based on a spring to engage the locking recess to pivot the rotary handle to various suitable operating positions. The locking mechanism not only stabilizes the rotating handle, but also provides safety, which is very important for safe tool operation.

The convenience of using such a hand tool enhances the power application by creating a favorable angle between the ground and the hand tool entering the ground to allow the user to perform the operation with less force. The hand tools of this creation are designed for people with different degrees of opening between the palm and the arm, as the difference can vary from 75 to 180 degrees. In particular, the angle of the handle may be necessary to maintain the wrist to prevent injury and improve strength applications. The handle should reflect the axis of the handle, which is typically 78 degrees horizontal and should be oriented so that the final tool axis matches the index finger.

The optimum tool angle depends on the user's posture, and the torque and strength that can be applied also depends on the working posture. For example, a repeated screw drive should be made on a horizontal surface above the elbow and pushed or pulled in the direction of the forearm, which is directly in front of the forearm. Therefore, the ability to change the angle of the hand tool is very important to provide more torque or strength and to minimize or eliminate injury and discomfort.

It is worth noting that this creation is a practical hand tool for people who use their left hand and right hand. For about 90% of the population, the preferred hand is also known as the "dominant hand", and this percentage is constant both culturally and genderily. Non-preferred hands tend to have a grip strength of about 94% of the preferred hand. Thus, for hand tools that can be used in either hand, the ability to rotate the angle of the hand tool allows the hand tool to adapt to the user's hand as the hand rotates, rather than adapting the user's hand to the tool.

For example, when holding a bow saw, many users have found that when their hands and grips are at an angle of 90 degrees instead of being held at the same level as a normal hacksaw, the hacksaw has a better push-pull effect. The user can turn the handle to a 90 degree angle. At the best angles and better grip, the user is able to generate more force while exerting less pressure on the user's arms and hands. This angle may be different for each person, but since the handles can be adjusted, each user can adjust the handle to an optimal angle to prevent injury while also increasing its productivity.

Figure 10 is an exploded view of the rotary handle of another preferred embodiment of the present invention. The rotary handle 1600 includes a D-shaped handle 1605 for manipulating the handle, one or more springs 1610, one or more tip pins 1615, at least one connector and rotating device 1620, and at least one connector housing 1625, the connector housing 1625 has a first end opening 1624 and a second end opening 1626, similar to that disclosed in the previous embodiments. The connector and rotating device 1620 includes a first end 1619 and a second end 1622. The second end 1622 is open to accommodate one end of the shovel. A ring 1621 is disposed on the edge of the second end 1622. The ring 1621 has a larger outer perimeter than the second end 1622. The larger outer perimeter of the ring is also greater than the inner perimeter of the second end opening 1626 of the connector housing 1625. In this embodiment, the first end 1619 is a seal. When fully assembled, the ends of the shovel are disposed through the second end opening 1626 of the connector housing 1625 and the opening of the second end of the connector and the rotating device 1620 and fit snugly within the connector and the interior of the rotating device 1620. The first end 1619 of the connector and rotating device 1620, the tip pin 1615, the spring 1610, and the interior of the hollow portion 1609 of the handle are sequentially pressed together. The first end 1619 and the interior of the hollow portion 1609 sandwich a spike and a spring. In order for the entire component to not separate, the D-shaped handle portion of the handle is threaded into the first end opening 1624 of the connector housing 1625. This is achieved by mating the threads, the male threads 1608 on the outer wall of the hollow portion 1609 and the internal threads on the inner circumference of the first end opening 1624 of the connector housing 1625. It should be understood that there are other attachment mechanisms to achieve the same effect, such as protrusions and L-shaped gap mechanisms in push-pull and turn.
