Abstract

To provide tongs that can be used when it is not appropriate to grasp something with hands due to burns or frostbite caused by high or low temperatures, or for hygiene reasons, and when it is necessary to grasp an object that is out of reach. [Solution] The tongs are made by movably connecting one end of two pressure plates of different lengths sandwiched between a polygon with two parallel sides and finger holes, and a plate with two claws attached to the other end of the shorter pressure plate, and one claw attached directly to the other end of the longer plate. By passing three or more fingers of one hand through the finger holes and moving the fingers, the two pressure plates can be opened and closed to grasp an object.

Description

[Technical Field]

[0001] This refers to tools that can be used when it is not appropriate to grab something with your hands due to burns or frostbite caused by high or low temperatures, or for hygiene reasons, or when it is necessary to grab something that is out of reach. [Background technology]

[0002] Whatever the object being grasped, gripping tools come in two types: with and without a shaft. Shafted tools usually have a gripping part on one side of the shaft and a part for the fingers on the other. Shaftless tongs are usually V-shaped and made of elastic material. There are many different types of tongs available on the market. Some tongs with a shaft have been designed with the gripping part and the part for the fingers on the same side of the shaft, but these were intended for use in cooking. This increases the selection of tongs suitable for hanging objects of a certain weight. [Prior art documents] [Patent documents]

[0004] [Non-Patent Document 1] MonotaRO Co., Ltd. (JP Tower Osaka 22nd Floor, 2-2-2 Umeda 3-chome, Kita-ku, Osaka 530-0001) Product Catalog Summary of the Invention [Problem to be solved by the invention]

[0005] We propose tools that can be used when it is not appropriate to grab something with your hands due to burns or frostbite caused by high or low temperatures, or for hygiene reasons, or when it is necessary to grab something that is out of reach. [Means for solving the problem]

[0006] The tongs have two pressure plates of different lengths sandwiched between a polygon having two parallel sides with finger holes bored therein, one end of which is movably connected to the other end of the shorter pressure plate, a plate with two claws attached to it is attached to the other end of the longer plate, and one claw is directly attached to the other end of the longer plate, and by passing three or more fingers of one hand through the finger holes and moving the fingers, the two pressure plates can be opened and closed to grasp an object. [Effects of the Invention]

[0007] The tongs of this invention have claws to prevent heavy objects from falling, making them extremely easy to hang. They can also be carried with one hand, close to the ground, reducing strain on the lower back. The tongs can be made to the appropriate length depending on the user's build. By using multiple tongs by one or more people, even very heavy objects can be hung. They can also be used to load and unload firewood for campfires, remove animal carcasses for road maintenance, and remove heavy objects that have fallen into gutters. Hard objects can be picked up even if they are not close to the center of gravity. [Brief explanation of the drawings]

[0008] [Figure 1] 1 is a perspective view of one embodiment of the tongs of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0009] The tongs' pressure plate and finger plate can be made of burnt cedar, but the material is not limited to burnt cedar. The hinges and claws of the tongs can be made of commercially available stainless steel hardware, but the material is not limited to stainless steel. [Example]

[0010] One 3.5cm diameter hole was drilled into each of the five-sided cedar boards measuring 3.5cm, 4.5cm, 49.5cm, 6cm, and 46.5cm, and two 3cm diameter holes were drilled into each of the five-sided cedar boards measuring 2.1cm, 4.5cm, 48cm, 6cm, and 46.5cm, and the surfaces of the boards were burned to turn them into charred cedar. The 1.5cm and 6cm rectangular faces were connected with hinges, and a 1.5cm, 4.5cm, 18cm rectangular claw mounting plate was attached to the 1.5cm, 4.5cm rectangular face of the shorter board. Two 1.8cm wide, 7.5cm long stainless steel stays were attached to the claw mounting plate, and one identical stainless steel stay was attached to the 1.5cm, 4.5cm rectangular face of the longer board, to form the tongs of this invention. The tongs were tested to confirm that a 5 kg concrete block could be suspended and carried by passing three fingers of one hand through the fingertip. [Industrial Applicability]

[0011] The tongs of this invention are expected to be in demand as gutter maintenance tools, road maintenance tools, research equipment, outdoor equipment, etc.

Claims

[Claim 1] The tongs have two presser plates of different lengths sandwiched between a polygon having two parallel sides with finger holes bored therein, one end of which is movably connected to the other end of which a plate with two claws is attached to the other end of the shorter presser plate, and one claw is directly attached to the other end of the longer plate, and three or more fingers of one hand are passed through the finger holes and moved to open and close the two presser plates and grasp an object.
