FIG. 1 is a partially sectional plan view showing a first embodiment of an openable / closable body restraint device (hereinafter simply referred to as a body restraint device) according to the present invention, and FIG. FIG. 3 is a sectional view of the restraining portion.

  The illustrated body restraint 1 includes a restraint portion 2, a lock portion 3 that locks when the restraint arm of the restraint portion 2 is closed, and a spring pressure retaining portion 4 that holds the restraint arm of the restraint portion 2 in an open state. It is composed of The restraining portion 2 is provided at one end of a tubular operating rod 10, and the lock portion 3 and the spring pressure holding portion 4 are formed on the operating rod 10.

  More specifically, the restraining portion 2 includes a pair of independent restraining arms 11 and 11 that can be freely opened and closed, a rack bar 12 disposed between the restraining arms 11 and 11, and the restraining arms 11 and 11. It is configured by a support member 13 that is pivotably attached to the rack bar 12 and through which the rack bar 12 is inserted. The restraint arms 11 and 11 are formed in a substantially hook shape in a planar shape, and curved surfaces 11a and 11a are formed on the inner surface so as to restrain the body of a thief, particularly hands or feet. Yes. Furthermore, the outer surfaces of the folded portions 11b and 11b folded back inside the restraining arms 11 and 11 are curved, and the teeth 11c and 11c are formed in a fan shape.

  A lower end portion of the rack bar 12 is slidably inserted into the operation rod 10 via a support member 13. On both side surfaces of the upper portion of the rack bar 12, teeth 12a, 12a meshing with the teeth 1c, 11c of the restraining arm are provided in parallel, a pressing portion 12b is provided at the tip, and the sliding rod is slidably inserted into the operation rod 10. A slide member 17 is connected to the lower end portion. As will be described later, a compression spring 18 that biases the slide bar 12 toward the slide member 17 is attached to the lower end of the slide bar 12.

  The restraining arms 11 and 11 are symmetrically arranged so as to face both sides of the rack bar 12, and the teeth 1 c and 11 c mesh with the teeth 12 a and 12 a, so that the rack bar 12 slides in the support member 13. Then, as will be described later, the restraining arms 11 and 11 rotate around the rotation shaft 21 with the support member 13 as described later.

  Further, the restraining arms 11 and 11 will be described in detail. The restraining arms 11 and 11 have bent portions 11d and 11d at intermediate portions so that the tip portions can intersect when closed. By forming the bent portions 11d and 11d, as shown in FIG. 2, the tip portions do not abut against the bent portions 11d and 11d and intersect each other vertically. Since the restraining arms 11 and 11 have the curved surfaces 11a and 11a and are formed so as to be able to intersect by forming the bent portions 11d and 11d, the gap formed by the curved surface is gradually increased when closed. It can be made small and can correspond to the thickness of the limbs.

  Guide rollers 19 and 19 are attached to the distal ends of the restraining arms 11 and 11 as guide members for facilitating insertion of limbs. It is preferable that the guide rollers 19 and 19 are non-returning rollers that rotate only inward and do not rotate outward. Further, since the guide rollers 19 and 19 guide the limbs to be sandwiched inside the restraining arms 11 and 11, the guide rollers 19 and 19 are attached in opposite directions to the distal ends of the restraining arms 11 and 11.

  The guide rollers 19, 19 can be omitted, and can be guide members having other configurations. For example, a guide plate that opens outward may be attached to the distal end portions of the restraining arms 11, 11, or the distal end portion may simply be a tapered surface.

The clamping plates 13a and 13a are integrally fixed by fixing pins 13c and 13c on both sides of the insertion hole 13b.

  A protruding piece 12 a is formed at the end of the rack bar 12, and a compression coil spring 18 is mounted between the protruding piece 12 a and the support member 13. The compression coil spring 18 described above is mounted so as to urge the rack bar 12 toward the lock portion 3 and the spring pressure holding portion 4.

  Therefore, when the restraining arms 11 and 11 of the restraining portion 2 are open, the pressing portion 12b of the rack bar 12 is pulled out and the compression coil spring 18 is compressed. On the contrary, when the compression coil spring 18 is released, the rack bar 12 is retracted by the urging force of the compression coil spring 18, and the teeth 12a and the teeth 11c are engaged with each other. By rotating about the center, the restraining arms 11, 11 are closed rapidly and smoothly.

  In the above embodiment, the bending portions 11d and 11d are formed on the restraining arms 11 and 11 so as to be able to cross each other. However, in order to cross the restraining arms 11 and 11, a bending portion is formed. When attaching the restraining arms 11 and 11 to the support member 13 without using them, the upper and lower axes may be attached in advance. When the restraining arms 11 and 11 are attached so as to intersect, the inner gap formed when the restraining arms 11 and 11 are closed can be gradually reduced.

  Further, the restraining arms 11 and 11 may be simply brought into contact with each other without intersecting each other, or may be configured to approach each other. Further, the shape of the restraining arms 11 and 11 may be a shape having a gap on the inner side when sandwiched, and is formed in a substantially L shape as shown in FIG. It may have a shape and is not particularly limited.
