AI Technical Summary

Problems solved by technology

(1) Since the existing steel fork is configured to suppress the prisoner by pressing the prisoner's body, it cannot be effectively used when there are no barriers such as the wall of the building and the fence or fence, (2) due to the The position of the object cannot stop the movement of the prisoner, etc. When the prisoner is being escorted, he is worried that the prisoner will escape. (3) Since the body is pressed by two rods, although the movement of the body can be restricted, the prisoner's hands or feet can move freely.
Therefore, in the follow-up operation, that is to wear handcuffs, and it is troublesome to work during the escort.
(4) For example, when subduing a prisoner holding a knife such as a knife, since the wrist of the prisoner can move freely, when the prisoner is handcuffed and escorted, there is a risk of being stabbed by the prisoner with a knife
Moreover, for example, due to the complicated structure of the locking means, etc., labor is laborious during manufacture, and the production cost is high.

Embodiment approach 1

[0044] Embodiment 1 includes a bearing member 28 pivotally supporting the opening / closing lever 23 and a mounting member 29 fixedly attaching the bearing member 28 to the front end of the branch lever 22 . Such as Figure 5 Shown in detail, the above-mentioned bearing component 28 includes a pair of bearing plates 30, 30 and a restricting plate 31 arranged at right angles to the upper ends of the front ends of the two bearing plates 30. Diameter-corresponding intervals of the rods 22 are arranged parallel to each other. The above-mentioned two bearing plates 30 have shaft holes 32, 32 and the rear parts of the shaft holes 32 are located at the rear part of the shaft holes 32 and have appropriate intervals in the up and down direction and are opposite to each other on the two bearing plates 30. 33 , 33 , the shaft hole 32 is close to the rear upper end of the limiting plate 31 and faces each other on the two bearing plates 30 .

[0045] The mounting part 29 includes a pair of...

Embodiment approach 2

[0058] The steel fork of the second embodiment is configured as described above, and is used in the same manner as the first embodiment. Therefore, the same effect as that of Embodiment 1 is obtained.

[0059] Fig. 9 is a view showing key parts of another embodiment (embodiment 3) of the steel fork of the present invention, Figure 9A is the profile view, Figure 9B is the floor plan. The steel fork of this embodiment is denoted by the same reference numerals as the common components of the structure already introduced in Embodiment 1, and the description thereof is omitted. Embodiment 3 is characterized in that a leaf spring 50 is used as the return means 24 .

Embodiment approach 3

[0060] Embodiment 3 includes a bearing mounting member 51 that also serves as an integrated structure of the above-mentioned bearing member 28 and mounting portion 29 . The mounting part 51 includes a pair of mounting plates 52, 52; a limiting plate 53 connected at right angles to the upper ends of the front ends of the two mounting plates 52 and a connecting plate 54 connected to the rear ends of the two mounting plates 52 at right angles. The plates 52 , 52 are arranged in parallel at intervals corresponding to the diameter of the branch rod 22 described above, and have an appropriate size.

[0061] Under the state that above-mentioned connecting plate 54 faces the outer side of two strands 21, make above-mentioned two mounting plates 52 combine with the front end of bifurcation rod 22, utilize screw 39 and nut 40 to fasten, and connecting member 51 is respectively fixed on two. On the bifurcated lever 22 , in addition, the above-mentioned two opening and closing levers 23 h...

Abstract

The invention provides a steel yoke capable of eliminating dangers of being stabed by a knife tool during overmastering a culprit using the knife tool. A steel yoke body (2) is mounted at a front endof a handle portion (1). The steel yoke body (2) includes two rods (21); movable opening / closing rods (23), (23) provided with base ends supported at front end portions of two branching rods (22) of the two rods (21), and only capable of being freely rotated towards an inner side direction of the two rods while being limited to move towards an outer side direction of the two rods; a resetting device (24) by which the two opening / closing rods (23) are rotated and back to original positions by effect of springs and the like; a restricting cord (26) with an end connected with a front end of an opening / closing rod (23) and the other end connected with a front end of the other opening / closing rod (23), and forming a hoop (44) having a proper size at an inner side portion of the two rods. The front ends of the two rods are opened / closed by rotating the two opening / closing rods.

Description

technical field [0001] The present invention mainly relates to a steel fork used by policemen and the like when suppressing prisoners, thugs or other suppressed persons. Background technique [0002] As existing steel forks such as Figure 12 As shown, the steel fork body 103 composed of two rods 104 bifurcated into a semicircle, U-shape or V-shape (shown as a semicircle) etc. A steel fork composed of a front end is known (for example, refer to patent documents 1 to 4). For such an existing steel fork, the policeman holds the handle 101 and presses the prisoner's body with the two rods 104 to suppress it. , so that the prisoner can be restrained. [0003] But existing steel fork has following problems. (1) Since the existing steel fork is configured to suppress the prisoner by pressing the prisoner's body, it cannot be effectively used when there are no barriers such as the wall of the building and the fence or fence, (2) due to the (3) Since the body is pressed by two ro...
