Description

Grip chopstick handles with flexible articulation

technical field

The invention relates to chopsticks, in particular to a handle for fixing common chopsticks.

Background technique

Chopsticks, an indispensable traditional tableware in daily life, are also widely used in other Asian countries. Usually a pair of chopsticks are two small and thin round rods with different materials and a single outline. Skillful use of this kind of chopsticks requires the upper limbs, especially the hands, sensitive coordination and proper force of dozens of joints and muscles. For people who are inconvenient to use, such as children, elderly people, and patients with hand dysfunction such as hand tremors and muscle stiffness, it is more difficult to control. Moreover, usually people will only use chopsticks with a certain hand. When this hand cannot use chopsticks temporarily or for a long time due to injury or other reasons, the other hand often brings trouble to the meal because it cannot use chopsticks skillfully and freely. inconvenient.

For skilled users, traditional chopsticks are mostly two cylinders or quasi-cylindrical bodies with a flat and smooth surface, which can easily lead to slipping during use. If the chopsticks slip off many times, it will not only affect the dining atmosphere and appetite, but also affect the user's mood. In addition, for some children and the elderly, when they use chopsticks, they often drop the food they eat on the table, floor or clothes, which not only causes food waste, but also makes it more troublesome for the watchers to clean up.

In addition, with the in-depth development of global integration, the world is becoming more and more open, the links between regions are closer, and the exchanges of eastern and western catering cultures are more frequent. More and more western foreigners come to countries including China and Japan. In eastern countries, more oriental restaurants go abroad and go to the world. Many foreigners in non-chopstick countries often encounter the above-mentioned similar problems when they taste Chinese food and sushi, because they do not know how to use chopsticks. It is also difficult to master the skills, especially when using it for the first time.

In fact, this is mainly because traditional chopsticks are not easy for these people to use well. This requires the flexibility and strength of its fingers and mutual cooperation, including the thumb, index finger, middle finger, and ring finger. Usually the tiger's mouth, the root of the thumb and the ring finger hold one chopstick still (opposite hand), and the head of the thumb cooperates with the index finger and middle finger to open and close the other chopstick to pick up food. Obviously, this is too high for the old, the weak, the sick, or the hand dysfunction, especially the thumb, index finger, and wrist dysfunction. On the other hand, for many foods in Chinese food, spoons and other tableware cannot completely replace chopsticks, and do not have the functions of chopsticks to hold, pick, mix, dial, poke, fork, grill, etc.; and chopsticks are especially important to the elderly: according to reports, if the elderly Use spoons instead of chopsticks for meals. It is easy to eat too much without knowing it with a large spoonful of food each time. Therefore, it is recommended to use chopsticks. The purpose is to reduce the amount of food eaten in each bite, prolong the meal time, and ensure full chewing, so as to facilitate Stomach digestion and absorption, etc.

The above situations are not inevitable if the chopsticks are designed properly. At present, many fruitful efforts have been made to improve chopsticks, many excellent structural solutions have been designed, and national patents have been approved. Although they are helpful to a certain extent for children, foreigners, those who just use chopsticks, those with hand dysfunction or those with crippled fingers, there are still deficiencies and need to be further improved:

Existing chopsticks are linear and mostly finger-operated. They are not "grasp" in the true sense—holding in the palm of the hand, but "finger pinching"—fingers (thumb, index finger, middle finger, etc.) pinch and use. Generally, when in use, chopsticks are placed on the palm of the hand, except for the thumb, the other four fingers and the palm of the hand are under the chopsticks, and the fingers pinch the chopsticks from below upwards. For example, "chopsticks" (CN201899282U) and "chopsticks for learning" (CN102612329B) users operate the chopsticks with their thumbs and index fingers, "power-assisted chopsticks" (CN101147648A) and "chopsticks" (CN201164314Y) users operate the chopsticks with their thumbs, index fingers, middle fingers, etc. , "Learning chopsticks" (CN101947042A) users operate with thumb, index finger, middle finger, and ring finger. Chopsticks with this structure are inconvenient to hold with the whole palm, for the following reasons: If you use the whole palm to hold the chopsticks from below without fingers, then when you pick them up and send them to your mouth, either the shoulders and elbows will be lifted too much, or the elbows will reach The rotation angle of the forearm is too large, and the user often feels awkward; if the chopsticks are held from the top down, when the food in the tableware with a certain depth, such as a bowl, is picked up, the wrist will be too flexed when the food is picked up, or the shoulder joint will be bent. If the lift is too large, even the human spine will be skewed to the other side of the body. For example, "chopsticks" (CN201164314Y), "chopsticks" (CN201445276U), "chopsticks" (CN201624456), and "a kind of chopsticks" (CN103126471A) all connect two straight chopsticks with elastic mechanism connectors, which can be operated by fingers, but not It is convenient to hold and use with the whole hand, so that when it picks up food or delivers it to the mouth, it exceeds the most suitable range of activity space for the human body, and does not meet the requirements of ergonomics.

Although some design structures add finger cots and rings in order to enhance the reliability of hands and chopsticks, such as "power-assisted chopsticks" (CN101147648A), "chopsticks" (CN201899282U), "easy-to-use chopsticks" (CN201139373Y), "chopsticks for the disabled "(CN201958504U), etc., but at the same time, it will make this structure inconvenient to put on and take off, the finger position is fixed and inflexible, and the operation of picking up and putting down the chopsticks during use is not direct.

There are other design structures that cannot be disassembled, or are inconvenient to dismantle, which brings trouble to cleaning and disinfection work. For example, "crank chopsticks" (CN1759792A) and "a kind of chopsticks" (CN1242971A) two chopsticks are connected by a hinge, and the head has convex teeth, anti-slip grooves, anti-slip teeth, etc. It is relatively troublesome to clean and disassemble; "chopsticks" ( CN201164314Y), "chopsticks" (CN201192246Y), "chopsticks" (CN201414646Y), all have springs, etc., which are inconvenient to disassemble, and the chopsticks are difficult to clean thoroughly; "learning chopsticks" (CN101947042A) contains many smaller parts , "easy-to-use chopsticks" (CN202104681U), etc. are not easy to disassemble.

Contents of the invention

The object of the present invention is to provide a gripping chopsticks handle with flexible joint connection in order to overcome the above-mentioned defects in the prior art.

In order to achieve the above object, the present invention adopts the following technical solutions:

A grasping chopsticks handle connected by flexible joints, including a skeleton, a handle, and a chopstick holder. The skeleton is divided into left and right connected elastic rods, which form a "V" shape. The positions are respectively fixedly connected with handles, and the front ends are respectively fixedly connected with chopstick holders.

The skeleton is made of an elastic body, and is bent in a V shape to form left and right symmetrical elastic rods, and the angle between the left and right symmetrical elastic rods is an acute angle.

The skeleton is composed of a non-elastic body and a rear-end elastic part, and the left and right non-elastic bodies are connected together through the rear-end elastic part to form an elastic rod.

The hand grip of the handle is provided with anti-skid dents.

The center of the chopstick holder is provided with a hole suitable for the insertion of ordinary chopsticks. The shape of the hole is circular or square, and the size of the hole is slightly smaller than the cross-sectional size of the chopsticks; The axis of the chopstick holder is inclined inwardly, forming an acute included angle.

Referring to Figure 1, with reference to Figure 2 and Figure 3, a grip-type chopsticks handle connected by flexible joints, including a skeleton 1, a handle 2, and a chopstick holder 3, the skeleton 1 is divided into two parts on the left and right, and a "V" is formed between the two parts The included angle of the font, the middle parts of the left and right parts are fixed with the handle 2, and the front ends of the left and right parts are fixed with the chopstick holder 3.

The skeleton 1 has certain elasticity, and is divided into two parts connected to the left and right. The two parts form an acute angle, and the left and right parts can also be connected together through elasticity. The middle parts of the left and right parts are fixed with a handle 2 , and the front ends of the left and right parts are fixed with chopstick holders 3 . Skeleton 1 material can be selected elastic materials such as steel bar, steel band, bamboo chip, plastics, also can select inelastic left and right two parts and connect left and right two parts with elastic body, forms whole skeleton and is elastic structure. The skeleton 1 is composed of a non-elastic body and a rear-end elastic part 11, and the left and right non-elastic bodies are connected together through the rear-end elastic part 11 to form an elastic rod (shown in FIG. 7 ).

The handles 2 are left and right, respectively fixed at the middle positions of the left and right parts of the skeleton 1. The front and rear positions are just right, and the front and rear centers are basically equal when the hands are grasped. There are anti-slip dents to increase the contact friction between hands and chopsticks.

Referring to Fig. 4 and Fig. 5, with reference to Fig. 2, the chopstick holder 3 has two left and right parts, which are respectively fixed on the front ends of the left and right parts of the skeleton 1, and the middle of the chopstick holder 3 is dug with an aperture suitable for ordinary chopsticks, and the shape of the hole is According to the shape of the inserted chopsticks 10, it can be cylindrical, rectangular, etc., so that the chopsticks 10 can be inserted from top to bottom or from bottom to top; Circular hole 32, just in time fits the shape of common chopsticks square circle excessive place, but aperture size will be slightly smaller than the size of chopsticks 10 that will be inserted and fixed, so that chopsticks 10 are inserted into chopsticks holder 3 and tightly fixed. The central axis of the dug left and right holes is downward relative to the skeleton 1, so that the inserted chopsticks 10 are approximately perpendicular to the plane where the skeleton 1 of the present invention is located, so as to meet the requirements of ergonomics, so that users feel more comfortable when using , Naturally, all related human joints are in the most suitable range of motion. Simultaneously, the two axes inwardly incline symmetrically to form an acute included angle, so that when the left and right parts of the skeleton 1 are close to each other but not attached together, the heads of the chopsticks inserted in the chopstick holder 3 touch and paste first, so as to pick up food.

Referring to Fig. 6 and Fig. 7, the form of the elastic connection of the left and right parts of the frame 2 can be diversified, for example, it can also be circular, similar to torsion springs and the like.

Referring to Fig. 8, in order to further increase the scope of adapting to common chopsticks of different sizes, the chopstick seat 3 can be replaced by an open seat 4, the open seat 4 is provided with an opening 41, and lugs 42 are respectively provided on both sides of the opening, and lugs 42 are worn with The bolt 43 can fix the inserted chopsticks 10 through a thumb nut 44 .
