Description

A kind of detachable chopsticks with limit function

technical field

The invention relates to a kind of tableware, in particular to a kind of chopsticks which have a position-limiting function when bounced off and are convenient to be disassembled and cleaned.

Background technique

Chopsticks used for dining are more commonly used in East Asian countries. Chopsticks are usually 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, the sensitive coordination and proper exertion of dozens of joints and muscles. For people who are inconvenient to use, such as elderly people or patients with hand dysfunction, it is more difficult to control; and usually people use chopsticks with one hand (usually the right hand), and the other hand cannot use it. If the hand that can use chopsticks is injured, etc. Temporary inability to use chopsticks often brings inconvenience to meals. 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 are going abroad to the world. Many foreigners in non-chopstick countries often encounter the above-mentioned similar problems when tasting Chinese food and sushi. Because they don't know how to use chopsticks, and it is difficult to master the skills in a short time, especially for the first time.

Even if some people know how to use chopsticks, they often cause the chopsticks to slip during use, which not only affects the dining atmosphere and appetite, but also affects the mood of the user; and although some people know how to use chopsticks, they often lose the food they eat during use. Drop on the table, floor or clothes, especially when some children and old people are picking up smooth and round food, such as vermicelli, long beans, peanuts, beans, shrimp, quail eggs, dumplings and other foods.

In fact, this is mainly because traditional chopsticks require the flexibility and cooperation of fingers: including the thumb, index finger, middle finger, and ring finger. When using traditional chopsticks, it is often necessary to press the tiger's mouth of the hand, the root of the thumb and the ring finger to press one chopstick (relative hand), and the thumb head cooperates with the index finger and middle finger to operate the opening and closing of 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 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 still operated by fingers. They are not "grasp" in the true sense—holding in the palm of the hand, but "pinching"—fingers (thumb, forefinger, middle finger, etc.) pinch and use. Generally, when using chopsticks, put the chopsticks on the palm of your hand—except the thumb, the other four fingers and the palm of your 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 forefingers, "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. Such as "chopsticks" (CN201164314Y), "chopsticks" (CN201445276U), "chopsticks" (CN201624456), and "a kind of chopsticks" (CN103126471A) all connect two straight chopsticks with a connecting piece with an elastic mechanism, 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 have added 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 simultaneously this structure can cause inconvenient to put on and take off, and finger position is fixed, inflexible, and the operation of picking up and putting down chopsticks in 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, the two chopsticks of "crank chopsticks" (CN1759792A) and "a kind of chopsticks" (CN1242971A) are connected by hinges. 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.

In addition to the above, the hygiene of chopsticks during use cannot be ignored. It mainly depends on the placement of the chopsticks. If the chopsticks are placed flat on the table, it is easy to be polluted due to contact with the surface of the table, which is unhygienic; if the chopsticks are placed on the edge of the bowl, it is unsightly and the chopsticks are easy to slip on the table. , also making its surface dirty. In order to solve the hygienic problem in the use of chopsticks, a separate chopstick holder can be used, and the chopsticks can be placed on the chopstick holder when not in use, so that the chopstick heads that are in contact with the food are empty and no longer in contact with the dining table, thereby maintaining cleanliness and sanitation. But this also has many disadvantages, because chopstick rests are mostly made of ceramics, metal, wood, bamboo, etc., and are small in size, cleaning, disinfection, and placement all mean extra work, time and expenses. I find it troublesome.

Contents of the invention

The object of the present invention is to provide a quick-detachable chopsticks with a position-limiting function in order to overcome the above-mentioned defects of the prior art. In order to achieve the above object, the present invention adopts the following technical solutions:

A kind of detachable chopsticks with a limit function, including: left half chopsticks, right half chopsticks, torsion spring or elastic ring for the shaft;

The left and right half chopsticks are connected by the shaft installed in the half shaft hole with a torsion spring to form a rotatable mechanism. The poles of the torsion spring are respectively It is stuck in the rear groove of the left and right chopsticks, so that the left and right chopsticks are automatically opened. When the opening reaches a predetermined angle, the inclined planes of the left and right chopsticks collide, limiting the further opening of the left and right chopsticks.

Preferably, the torsion spring for the shaft can be in the form of a handle torsion spring, one or two of which contain a handle, and the size of the handle is suitable for the thumb and forefinger to pinch and pull the shaft to separate the left and right half of the chopsticks from the torsion spring, or suitable for a Insert a finger into it and pull out the torsion spring.

Preferably, the form of connection between the left and right half chopsticks can directly form a rotatable connection mechanism through the elastic ring installed at the rear end of the chopsticks, wherein the inner side of the rear end of the left half chopsticks includes a half shaft hole and upper and lower limit discs, A half shaft protrudes from the inner side of the rear end of the right half chopsticks, and the two cooperate with each other to form a detachable rotating structure. Through the elastic rings sleeved on the rear ends of the left and right chopsticks, a rotatable connection structure with self-bounce function is further formed.

Preferably, a triangle structure is connected to the outside of the rear ends of the left and right half chopsticks, and the slopes of the two hypotenuses of the triangle are different:

The forward slope from the rear end of the chopsticks is small, so that the elastic ring can cross the triangle when it is set forward from the rear end of the chopsticks;

The backward slope from the front end of the chopsticks is relatively large to prevent the elastic ring from slipping off from the back end of the chopsticks in reverse when the chopsticks are working.

Preferably, when the left and right half chopsticks are removed, the rear shafts are torsion springs or elastic rings, then the left and right chopsticks are automatically separated, and when they are installed, the two are connected together to form dining chopsticks with self-bounce function.

The present invention adopts the elastic connection of the left and right half chopsticks, which can be quickly separated, which is convenient to remove the left and right half chopsticks for cleaning in time; the left and right parts of the chopsticks are automatically separated by using the elastic recovery force of the torsion spring and the rear limit function, eliminating the need for chopsticks to be stretched when eating The action of opening and closing the chopsticks with the hands in the process of opening and closing; the use of thick handles and ergonomic bending design reduces the operating requirements on the distal and middle joints of the user's fingers, making it unnecessary to learn to pick up the chopsticks It can be used regardless of left and right hands, making hand operation more comfortable and natural, and taking food more convenient. The present invention has broad market prospects and can be used in kindergartens, foreign-related Chinese restaurants, Japanese restaurants, welfare homes, home care for the elderly, inpatient departments of individual hospitals, and the like.
