Description

[Technical Field]

[0001] (0001) This invention relates to a self-help device that is attached to the grip of a writing instrument, and more specifically to a writing aid or writing assistant that, when gripping with the thumb and index finger, provides a stable grip for the space between the thumb and index finger and the remaining three fingers, relieves finger fatigue, prevents calluses, and also serves as a welfare tool to promote independent writing as part of everyday activities. [Background technology]

[0002] (0002) Japan's aging rate (the percentage of the total population aged 65 or older) is progressing at an unprecedented rate, reaching 29.3% as of October 1, 2024 (Non-Patent Document 1), to the point where there are fewer than four young people supporting one elderly person. (0003) Meanwhile, advances in medicine have made it possible to improve or slow the progression of stroke, head trauma, and neurological disorders, and rehabilitation techniques have also been used to reduce the severity of these conditions. (0004) Physical characteristics associated with aging include locomotive syndrome, which indicates a decline in motor function; frailty, which indicates a decline in function including that of each bodily organ; disuse syndrome, which indicates a decline in joint range of motion and muscle strength due to reduced opportunities to move the body; and a decline in cognitive function, particularly the rapid increase in patients with mild cognitive impairment (MCI), which has become a problem in recent years.All of these conditions result in declines in motor function, muscle strength, and difficulty performing fine tasks, making it difficult to use an ordinary pencil or pen. (0005) People with physical disabilities due to stroke, head injury, or cranial nerve disease are characterized by paralysis, muscle weakness in the hands, and finger tremors, which cause difficulty in fine movements of the hands and fingers and stable gripping of the fingers. As with the elderly, these often make it difficult to use ordinary pencils or pens. (0006) Furthermore, elderly people and people with disabilities desire a sense of purpose in life and seek a "purpose in life." The word "purpose in life" is unique to Japan, and adult coloring books are often used as hobbies or in rehabilitation settings, suggesting that independence in daily life is essential. (0007) In general, children and women are thought to have less muscle strength than healthy adult men, and there is thought to be room for improvement in phenomena such as the strength of writing pressure and fatigue caused by writing. (0008) Conventional writing pen shafts are round or hexagonal in shape, and in order to prevent slippage at the grip, various devices and techniques have been used to provide finger slip prevention either on the outside or on the shaft itself. (0009) In detail, in addition to the anti-slip effect, in order to prevent finger fatigue and calluses (so-called pen calluses), various measures and designs have been taken to maintain elasticity by using rubber tubes with an uneven shape, silicone processing, or increasing the thickness of the grip part of the shaft itself, as shown in Reference 1. (0011) In addition, there have been many efforts to devise and design writing implements that make writing easier, and some, such as the one in Reference 2, have an external writing implement holder attached to the pen shaft. (0012) Furthermore, from a medical perspective, devices such as those disclosed in Patent Document 3 have been developed to assist with grasping actions (action of grasping with the thumb and index finger).

[0004] [Non-Patent Document 1] (0014) Non-patent document 1: Reiwa 7 White Paper on Aging Society, Cabinet Office Summary of the Invention [Problem to be solved by the invention]

[0005] (0015) The aforementioned grip anti-slip devices, writing implement holders, and gripping motion assist devices each have their own unique functions, and no assistive device has been developed that covers all of them. In particular, writing implement holders and gripping motion assist devices have traditionally emphasized their function as an orthosis, making them difficult to put on by the user and making them difficult to put on easily. The challenge is to overcome these conventional problems and provide writing aids and assistive devices that are comfortable and easy to use by the user and also have anti-slip and callus prevention functions. [Means for solving the problem]

[0006] (0016) In order to solve the above-mentioned problems, this invention provides (1) a thick grip to improve gripping strength and prevent finger fatigue, (2) a fixing system that is compatible with the thickness of the shaft of either a pencil or a pen, (3) a device that is placed between the thumb and index finger without being fixed to improve gripping strength and gripping strength, and (4) a grip part that improves elasticity to prevent calluses and relieve finger fatigue, and by incorporating the features of (1) to (4), it is possible to create a self-use writing aid and a universal design for a writing aid that can be used by oneself. [Effects of the Invention]

[0007] (0017) By using the writing aid / assistant of this invention, there is no need to fix or attach a band, and it becomes possible to easily grasp and hold the writing implement by oneself, and it also has anti-slip and callus prevention functions. (0018) As a result, firstly, it will enable the elderly and physically disabled to have a meaningful writing function that will help them to be independent in their daily lives, and by broadening the range of their hobbies, it will be possible for it to function as a welfare equipment that will connect to the "purpose in life" that is unique to Japan, as well as "confidence" and "self-esteem." It will also be usable as a writing aid that will make writing easier for people of all ages and genders, including children and women. [Brief explanation of the drawings]

[Figure 5] This is a side view of the basic structure when worn. [Figure 6] This is a bottom view of the basic structure when installed. [Figure 7] FIG. 1 is a perspective view of a basic structure of an embodiment; DETAILED DESCRIPTION OF THE INVENTION

[0009] (0019) This article describes various types of self-help devices and assistive devices that can be used to solve the problems mentioned above. <Form 1> (0020) It has a part (Figure 7 - number 12) that can be held between the user's thumb and index finger, and the holding part allows the other three fingers to bend naturally, making it easy to grasp and hold the writing instrument. <Form 2> (0021) In form 1, the part that can be held between the user's thumb and index finger has a "spring" function (Figure 6-number 9), making it possible to accommodate the various sizes of the shafts of pencils and thick pens. <Form 3> (0022) In types 1 and 2, a hard material is used to ensure durability, and a through hole is provided in the center to prevent finger fatigue due to the weight (Figure 1 - number 5). <Form 4> (0023) The grip part of the writing implement is a thick cylindrical rubber (Figure 1 - number 4) attached to the front of the mobile phone 1 to 3, so that the diameter of the cylinder can be changed to accommodate each size of Form 2. <Form 5> (0024) The surface of Form 4 (Figure 1 - number 6) is made of a soft material with anti-slip properties and elasticity / resilience, and its outer surface is made of an uneven adhesive resin material (gel sheet, etc.). [Example]

[0010] (0025) As an example of this invention, as shown in Figure 8, a basic form is formed by inserting a writing implement (number 8) into the hollow portion (number 7) of the T-shaped holder clamping shaft portion (number 2) and the grip shaft portion (number 4) attached to it, and then placing it between the thumb and index finger and lightly gripping the holding body portion of the T-shaped holder to write, which allows for stable writing without exerting force on the fingers. [Industrial Applicability]

[0011] (0026) It can be attached to conventional writing implements at low cost and can be used with a variety of writing implements. (0027) Since it is possible to improve the stability of the fingers when writing and the grip strength of the thumb and index finger, it makes writing easier for people of all ages and genders, including the elderly, physically disabled, children, and women, regardless of whether they have a disability or not. (0028) It is possible to prevent finger fatigue caused by writing, pen calluses, and tendonitis. (0029) Due to the above-mentioned possibilities, it can be used as a writing aid or auxiliary tool as welfare equipment that can lead to "creating a sense of purpose in life" and "preventing and reducing industrial accidents" for the elderly, physically disabled people, and dementia patients. (0027) When commercializing this invention, costs can be reduced by using molds for existing office supplies, such as shapes and materials, and the product structure is not complicated, which is an advantage.
