Abstract

A knitted grip-reinforced glove (1) comprises a hand portion (2) having a palmar side (3) and a dorsal side (4), and at least one finger portion (5), wherein the glove is knitted from a stretchable material, at least one artificial tendon (6) is positioned on the outside or inside of the knitted material, and the finger portion is knitted such that at least one fingertip (7) has restricted stretching. The finger portion is knitted to have at least one reinforced area on the dorsal side of the glove in a direction intersecting the longitudinal direction of the finger portion, while the palmar side of the finger portion and the glove have a knitted structure that is flexible in at least two directions, the reinforced area extends downward on each side of the finger portion to form a reinforced side, and at least one artificial tendon is slidably attached to the reinforced side.

Description

This invention relates to a knitted grip-enhancing glove made of a stretchable material. Existing grip-enhancing gloves on the market are made by cutting and sewing together textiles. Often, these gloves are designed to be worn over protective gloves. Cut-and-sew gloves inevitably have seams, which can be uncomfortable for the wearer. Because seams do not stretch, for comfort, the seam allowances must be flared outwards away from the wearer's hand. Another problem with cut-and-sew gloves is the integration of force-transmitting components and electrical components, such as pressure sensors and cables. This is addressed, for example, by using textile layering disclosed in WO2017/207507. However, using multiple layers has the disadvantage of restricting the wearer's freedom of movement and making it warm to work with the gloves on. Other drawbacks include limited tactile feedback from objects interacting with the hand, making it difficult to manipulate small objects like bolts. Current glove manufacturing is labor-intensive. The specialized nature and quality requirements of grip-enhanced gloves demand meticulous one-on-one training for dedicated sewing workers. This training needs to be repeated every time the glove design changes. The outcome depends heavily on manual sewing techniques and the knowledge of individual craftsmen. This means there is variability in the textile of gloves produced within a single batch. The functionality of the gloves tolerates very little error. Efficient force transfer to the fingers depends on tolerances down to the millimeter. In current cut-and-sew production, the tolerance for sewing is 2 millimeters. Even a 1-millimeter error can cause the glove's fingers to twist during the operation of the artificial tendon. This finger twisting not only causes discomfort but can also displace sensors from their proper position, leading to an unbalanced force distribution. In gloves that use multiple layers, problems can arise such as the layers slipping inside, leading to malfunctions and an unstable gripping experience for the wearer. Therefore, there is a need for gloves with a small number of layers, preferably gloves that integrate sensors, communication, wiring, and power transmission functions with as few layers as possible. WO2019010520 and WO2021087557 disclose seamless knitted grip-enhancing gloves with reinforced bands. The reinforced bands wrap around the fingers and hand. These bands add tackiness that allows force from tendons to adhere, thus enhancing grip. This type of glove has the advantage of being quick to produce and therefore having low manufacturing costs. However, gloves manufactured in this way have several drawbacks. One problem with gloves knitted in this way is that because the bands are knitted around the entire circumference of the fingers and parts of the hand, it is difficult to provide a good fit for all variations in hand proportions within a single size. Even when using gloves of the same size, people with wider or narrower fingers may find the fingers of the glove too tight or too loose due to the bands. Fingers of a glove that do not fit tightly enough around the wearer's fingers are at risk of moving relative to the fingers, and proper control of the grip-enhancing glove is not guaranteed. Another problem is the difficulty in properly connecting the fingers and wrist during force transmission. Furthermore, gloves made with woven bands have limited possibilities for adding layers such as pockets or channels for integrating cables, tendons, and sensors. Other examples of gloves using knitting materials include WO2015134336 and US2021301432.
