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 high or low temperature burns or frostbite, 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 high or low temperature burns or frostbite, 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 are made by movably connecting one end of two pressure plates of the same size, attaching claws facing each other near the other end, and attaching a finger-through plate to each of the pressure plates near the connecting parts on the outside, so that three or more fingers of one hand can be passed through the two finger-through plates and the two pressure plates can be opened and closed by moving the fingers 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 and easy to carry 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 physique. By using multiple tongs by one or more people, even very heavy objects can be hung. They can also be used to prevent burns at bonfires, for road maintenance to remove animal carcasses, and for removing heavy objects that have fallen into gutters. [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' clamping plate and finger guide plate of this invention can be made of burnt cedar, but the material is not limited to burnt cedar. The tongs' prongs of this invention can be made of commercially available stainless steel snap fittings, but the material is not limited to stainless steel. [Example]

[0010] Two cedar boards, each 1.5 cm thick, 4.5 cm wide, and 48 cm long, were charred using a gas burner. One end was connected with a hinge, and two 5 cm long stainless steel snap brackets and one other stainless steel snap bracket were attached to the other end, facing in opposite directions. A charred cedar finger plate, 1.5 cm thick, 6 cm wide, and 4.5 cm high with one 3.5 cm diameter hole and another 1.5 cm thick, 9 cm wide, and 4 cm high with two 3 cm diameter holes, was attached outward near the joint of the pressure plate to make the tongs. It was confirmed that these tongs could be used to hang and carry a 12 kg concrete block by placing three fingers through the finger plates on one hand. [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 are made by movably connecting one end of two pressing plates of the same size to each other, attaching claws to the vicinity of the other end so as to face each other, and attaching one finger-through plate to each pressing plate near the connecting part on the outside, so that three or more fingers of one hand can be passed through the two finger-through plates and the two pressing plates can be opened and closed by moving the fingers to grasp an object.
