Opening / closing tongue

Abstract

To provide an opening / closing tongue capable of enlarging a width between two arms when objects different in size, weight, and shape are grasped by sandwiching by the tongue and also eliminating worry about dropping the tongue.SOLUTION: A tongue includes: two arms having a distal end and a terminal end; and a leaf spring for connecting the terminal ends of the two arms. Finger rings to allow a finger to be inserted in a nearly right-angle direction with respect to a longitudinal direction of the two arms are arranged between the distal end and the terminal end in the two arms. The two arms are opened / closed by using opening and grip of fingers.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to an opening and closing tongs having finger rings attached to both arms of the tongs. [Background technology]

[0002] Conventionally, tongs have a spring-loaded tip that opens, and when used, the arm is held between the thumb and index finger, with the remaining fingers simply supported on the arm to prevent them from dropping. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP2018-050713A [Patent Document 2] JP2018-143696A [Patent Document 3] Patent Publication No. 2021-094197 [Patent Document 4] Patent Publication No. 2023-000026 Summary of the Invention [Problem to be solved by the invention]

[0004] The conventional techniques have the following drawbacks: This is fine when clamping the same items one after the other slowly, but when trying to clamp irregularly shaped items of different sizes and weights one after the other, the arms open just by the repulsive force of the leaf spring, so there is a limit to how far the tongs can be clamped, and if you want to open them further, you have to use your other hand to hold them open, and because the tongs are only being held down by your fingers, they may fall. The present invention has been made in order to eliminate the above-mentioned drawbacks.

[0005] A finger ring (3) for the thumb is provided between the end (5) and tip (6) of the arm (1) of the tongs, and finger rings (4) for the remaining four fingers are provided between the end (5) and tip (7) of one arm (2). The present invention provides an opening and closing tongs having the above-mentioned configuration.

[0006] The tips (6) and (7) of conventional tongs have a limit to how wide they can be opened using only the repulsive force of the leaf spring (8), and opening them any wider can lead to the tongs dropping from the hand. However, in the present invention, by providing finger rings (3) and (4), the opening and closing of the fingers can be maximized, and it is possible to hold objects that are wider than the limit of the opening width of the leaf spring (8). This eliminates the need to use different tongs according to their shape and size, as in the past. Since all the fingers of one hand fit within the finger rings (3) and (4), the opening and closing of the fingers and grip strength can be maximized, and there is no need to worry about dropping the tongs. With the opening and closing tongs of the present invention, the tongs can be opened and closed freely and can be used comfortably as part of one hand. [Brief description of the drawings]

[0007] [Figure 1] FIG. 2 is a plan view of the present invention. [Diagram 2] FIG. 2 is a side view of the present invention. [Diagram 3] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described. As shown in Fig. 1, the tips (6) and (7) are the point of application (C) for pinching an object, and the force point (B) is located between the fulcrum (A) and the force point (C) of the tongs. Finger rings (3) and (4) are provided at the position of the force point (B). By inserting all the fingers of one hand into the rings, the finger spread and the total grip strength of one hand can be maximized, and the tongs can be opened and closed freely without worrying about dropping them. The present invention provides an opening and closing tongs having the above-mentioned configuration. [Explanation of symbols]
