Abstract
A hand restraining band clamp strap 1 and a head 2 through which the shank may be passed to form a loop to receive the wrists of a person to be restrained. An end piece 3 forms an abutment for the hand of the person applying the restraint and may be fitted after passing strap 1 through head 2. A pawl 12, held loosely within the head 2, permits the strap to pass freely in the tightening direction and allows some relaxation from the fully tightened position while it is carried by movement of the strap to the position of Fig. 9, where it is detained by stop 15. <IMAGE>
Description
SPECIFICATION
Improved hand restraint
Conventional handcuffs are made from metal and have a latching mechanism to permit them to be locked and reopened. The conventional handcuffs are expensive and cannot be applied quickly when, for example, a large number of persons must be immobilised, as in a riot. Certain police and military forces have employed as a restraint a tie of the type consisting of a flat plastics strap having a slotted head through which the tail end of the strap is passed before the tie is tightened. A pawl may be provided within the head to engage the teeth or serrations on one surface of the shank of the strap to prevent the strap loosening. Such a strap may be of the type described and illustrated in patent specification
No. 1 519 233.However, there is a risk that the use of such a strap as a hand restraint may interfere with the circulation of the blood when pulled tight about the wrists of the person detailed. In addition, such a strap cannot be applied quickly to the wrists.
The restraint proposed herein is designed to allow it to be applied quickly but without interfering with bodily circulation.

Figure 12 is a cross-section through the shank of the restraint, and
Figure 13 is an end elvation of the pawl.
Referring to Figure 1, the proposed hand restraint comprises a strap having a flexible flat shank 1 moulded in one piece with a head 2 through which the tail end of the shank may be passed before an end piece 3 is fitted in place. A large loop is thereby formed in the strap as shown in Figure 1. A finger piece 21 on the head facilitates handling the head. Herein, the expressions "front" and "rear" refer to the left and right hand ends as viewed in Figure 1, "upper" and "lower" to the top and bottom sides as viewed in Figure 1, and "outer surface" to the side of the strap which forms the outer surface of the loop, respectively.
In use, after a loop has been formed and the end piece 3 applied, the restraint is held near its tail end by the user. The end pieces 3 forms an abutment against which rests the little finger of the hand of the user, so allowing the restraint to be easily manipulated and the loop to be slipped over both wrists of a person to be restrained. By pulling on the tail end of the strap against the resistance provided by the wrists, using the end piece as an abutment, the shank of the strap slips through the head and tightens about the wrists. A pawl within the head cooperates with a row of fine teeth or serrations along the outer surface of the strap to prevent the restraint from being released once it has been applied. The inner surface of the shank is smooth. The restraint is removed by cutting through the shank with a cutter kept at the police station or in a police vehicle, for example.
The pawl has a degree of freedom of movement relative to the head and the loop can expand sufficiently to avoid constricting the wrists. The restraint may be moulded from nylon or any suitable plastics material in three separate components, namely the head and strap, the pawl, and the end piece, respectively.
Referring now to Figures 2, 3 and 8 to 1 the head of the restraint comprises a generally rectangular, prismatic body, having front and rear end walls, upper, lower and side walls, all bounding a generally rectangular cavity within the body. Conveniently, the body tapers towards the front end. The front wall of the head has an aperture 5 which opens into the cavity within the head. Corners 20 projecting into the aperture 5 render it generally T-shaped. The rear wall of the head has an aperture 6 rendered C-shaped by a stop portion 15 and which opens into the cavity and is aligned with the aperture 5. The stop 15 is reinforced by a bead 16.The lateral sides of the forward end of the head are relieved by slots 7 which at their forward ends penetrate into the cavity in line with the wider part of the aperture 5 to give the forward end of the head a degree of flexibility. The height of the cavity within the head is reduced at its rearward end by a rib 8 on the underside of the upper wall terminating at its forward end in an oblique surface 9.
The shank of the strap has its root in one piece with the lower wall of the head near its rearward end. As shown in Figure 12 the shank has lateral ribs 11 bounding a trough formed at its bottom with the teeth or serrations 10 which are ratchetlike, in the sense that they have flanks perpendicular to the plane of the strap. The width of the strap, dimension a as viewed in Figure 12 corresponds substantially to the overall width a' of the apertures in the front and rear walls while the thickness b of the strap corresponds substantially to the height b' of the wider part of the aperture 5, see Figure 10. It will be appreciated that the strap will pass through the head in such a way as to block the wider part of the aperture 5 and the lower part of the aperture 6. The stop 1 5 just touches the surfaces of the teeth of the inserted strap.
Referring to Figures 7 and 9, the pawl has a main body portion 13 from which project lateral wings 1 4. Formed on the underside of the body are teeth or serrations complementary to those of the strap. The overall width of the pawl a" in
Figure 13 is substantially equal to the overall width a of the strap in Figure 12, while the width c' of the body of the pawl is substantially equal to the width c of the trough of the strap. The upper,
rearward edge of the pawl as it is arranged within
the head is chamfered. The pawl is dimensioned to
fit into the recess between the front wall of the
head and the rib 8, as shown in Figure 8, and in
this position to ride over the teeth or serrations of
the strap as it is pulled through the head in the
direction A.The wings of the pawl cooperate with
a stop formed by the corner portions 20 of the
front wall to prevent its escape through the
aperture 5. During this movement of the strap, the
loop tightens about the wrists. Once tension is
released, the strap may be retracted in the
direction B. The teeth or serrations on the strap
cooperate with those on the pawl and carry the
pawl rearwardly. The complementary oblique
surfaces 9 and 19 on the rib 8 and the pawl, cam
the pawl downwards so that its teeth tightly
intermesh with the teeth on the strap. The pawl is
thus held tightly against the strap and brought Into
contact with the stop 15 which prevents further
movement of the strap and pawl. During this small
amount of lost motion, amounting to say 5 to
15 mm, the loop expands somewhat, but cannot
be totally released.
The free ends of the strap is bevelled as shown
in Figure 4 at 17. During assembly, the end of the
strap may be held temporarily while this bevelled
portion lies in the aperture 5, so that the strap
does not block the aperture entirely. In this
position, the pawl may be slipped into the cavity
within the head before being broken off from the
sprue on which it was moulded. The strap is now
pushed through the head into the position illus
trated in Figure 1 so that the ribs along the side of
the strap block the side portions of the aperture 5
and the pawl is prevented from escaping from the
head.
Spaced slightly from the free end of the strap is
a hole 18 into which penetrates a lug 19 within
the central opening of the end piece 3 when the
latter is pushed onto the end of the strap.
The restraint described herein may have uses
as a bundling strap in industry and commerce.
Modifications may be made to the construction
illustrated. In particular, the head may be formed
separately from the strap. Further, two limbs of a suitably formed strap may pass through a head and may cooperate with respective pawl portions.
