Description
The present invention relates generally to a restraining apparatus similar to handcuffs; and, more particularly, to an inexpensive, easily carried, easily concealed and easily used restraining apparatus and method of restraint employing the same.
Background of the Invention
Metal handcuffs are expensive to purchase, somewhat cumbersome to use, difficult to carry and they are difficult to conceal. Because of this problem with conventional metal handcuffs, restraining devices similar to that shown in U.S. Pat. No. 4,138,770 to Barrette et al. have been used as a restraining device by placing one of the devices around each wrist of a person to be restrained and another such device is looped through the other two loops extending around the wrists. One of the problems with using the Barrette et al. device is that an officer must have help from another officer or from the person being restrained.
U.S. Pat. No. 4,071,023 to Gregory uses a nylon or plastic restraining device which has two loop forming sections which are formed together in one piece. A problem with this device is that it is not easily stored because it does not fold flat and there is no convenient way to tie one prisoner's restraining device to another's or to a stationary object.
Accordingly, there exists the need for a restraining apparatus which is inexpensive, which is easily carried, concealed and used by one person. There is also a need for a restraining device which is less likely to injure wrists and ankles while at the same time being more universal in providing a greater allowance for varying sizes of wrists and ankles.
Summary of the Invention
The present invention relates to a restraining apparatus, including a body portion having a first flexible arm with one end attached to a lower end of the body portion, the first arm extending outwardly and downwardly from the body portion. A second similar arm is provided laterally-spaced from the first arm and likewise having one end attached to the lower end of the body portion, the second arm extending outwardly and downwardly from the body portion parallel to the first arm. A first adjustable locking member is disposed on the body portion above the first arm, for receiving and locking a free end of the first arm thereto when it is looped around and pushed into such locking mechanism. A second locking mechanism is disposed, laterally-spaced from the first locking mechanism, on the body portion above the second arm, for receiving and locking a free end of the second arm to the body portion when the second arm is looped around and pushed into the second adjustable locking mechanism.
An object of the present invention is to provide an improved restraining apparatus for use by law enforcement officers.
Another object of the present invention is to provide a restraining apparatus which is extremely universal to accommodate varying sizes of wrists and ankles.
Another object of the present invention is to provide a restraining apparatus which is inexpensive to make and easy and dependable to use.
A further object of the present invention is to provide a restraining apparatus which is easily concealed and easily carried by a law enforcement officer.
A still further object of the present invention is to provide a restraining apparatus which has a connector which is easily connected to a rope for interconnecting several persons being restrained by such restraining devices or, alternatively, such attachment structures can be utilized to store on wall hooks or the like for immediate retrieval.
Other objects, advantages and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.

Detailed Description of the Preferred Embodiment
As shown in FIG. 1, a restraining apparatus in the form of handcuffs 10, in accordance with the present invention, has one flexible arm 11 extending around a right wrist 12 and another flexible arm 13 extending around a left wrist 14 of a person to be restrained.
The arms 11, 13 extend longitudinally outwardly and downwardly from laterally-spaced positions along a lower end edge of a body portion 15. A tab 16 having an attachment hole 17 therein is located at an upper end of the body portion 15.
In order to use the restraining device 10, it is merely placed with the arms 11 and 13 extending downwardly between the wrists 12 and 14, and the tab 16 extending upwardly. The flexible arm 11 is then looped around the right wrist 12 and into an attachment opening 21 (FIG. 2) until it is snug. The arm 13 is grasped and looped around the left wrist 14 and into the opening 23. Each arm 11, 13 may take the form of a nylon strap and retention of the strap in the opening 21, 23 can be accomplished by ratchet means.
Referring to FIG. 4, a ratchet member 24 having teeth 25 is biased in the downward direction on body portion 15 to interact with corresponding teeth 26 on the straps 11, 13. The arrangement is similar to that used to lock a free end of a flexible strap in an opening of known cable ties and the like which have a single strap which tightens around a coiled cable. It will be understood that both of the openings 21 and 23 have such structures as shown in FIG. 4 therein, so that when the strap 11, 13 is inserted into the respective opening 21, 23, the ratchet lock 24 will be pushed downwardly but will bounce along against the teeth 26 on the flexible strap 21, 23. However, when it is desired to withdraw the strap 11, 13 by pulling it in the opposite direction out of the opening 21, 23, interaction of the ratchet teeth 25, 26 will prevent its withdrawal unless the ratchet member 24 is forced upwardly against the downward bias, such as by means of a screwdriver or the like inserted between the teeth 25, 26. Other ratchet arrangements, such as that shown in U.S. Pat. No. 4,138,770, can also be used. It is noted that for avoidance of injury, teeth 26 are disposed only on those parts of the arms 11, 12 that will be outside the loops formed when applied as shown in FIG. 1. No teeth are disposed on either side of the parts of the straps 11, 13 that extend between the wrists, and teeth are formed only on the external sides of the nonadjacent parts that are directed back on themselves toward the openings 21, 23 to form the loops. It is also noted that a rear view of the strap 11 and opening 21, will appear identical to the shown front view of the strap 13 and opening 23; and vice versa.
FIG. 5 shows the embodiment 10 of the present invention in a storage position with the straps 11, 13 folded at integral hinged portions 31, 33 constructed by reducing the thickness of the straps 11, 13 at locations midway between the ends. The free end of the strap 11 extends through a loop or securing ring 41 attached to the body 15 and located above the lock entry 21. The free end of the strap 13 extends through a loop 43 connected to the body 15. Folding in this manner forms a very compact structure which can easily be placed in a shirt, jacket or trouser pocket of a standard issue police or military uniform. It will be appreciated that large quantities can be stored in a very small space, and they also can be stored on hooks or nails through the holes 17.
The dual strap restraining device 10 is preferably formed of nylon plastic with a tensile strength of 300 pounds or more. The restraining device 10 is also preferably formed as a one-piece, integral unit.
The attaching opening 17 in tab 16 permits the user to connect several prisoners together by placing a rope or the like through the opening 17 or to even connect the person being restrained to some other object. The device 10 can, for example, be used also as a leg shackle with several prisoners connected together by joining the loops formed by the openings 17. Also, where a person being restrained has missing arms of legs, the remaining extremity can be secured to a belt, other extremity or other items such as to an automobile or the like. Positioning the tab 16 and opening 17 away from the straps 11, 13 and the locking mechanisms 24 permits manually grabbing the tab 16 or connecting the respective tabs 16 of several units 10, without injuring the prisoner.
Using dual straps, so that one strap is applied to each wrist or ankle, shortens the handcuff to approximately one-half the length of traditional one strap flexible handcuffs. All surface edges are preferably rounded to avoid cuts, and strap surfaces that wrap around the wrist or ankle are smooth to avoid locking cuts. Each strap preferably has an internal circumference that exceeds standard steel handcuffs by about two inches, allowing for a broader range of wrist/ankle sizes.
It will be appreciated that the foregoing description is presented by way of example only and that modifications and variations of the presented embodiments are possible, which are within the scope of the appended claims.
