Referring to the drawings, the clip A includes first and

second plate members

1, 2 pivotally connected to each other, each of said plate members having at one end thereof a

jaw

3, 4 each provided with

soft pads

5, 6 between which an article to be clipped is resiliently pressed when the jaws are in the closed position as shown in FIG. 2.

The first plate member 1 is provided with an integral pivotal element 7 bridging over the inner surface thereof and the second plate member 2 has a receiving element 8 integrally provided on the outer surface thereof.

The pivotal element 7 comprises a pair of

legs

7a, 7a extending perpendicularly to the inner surface of the plate member 1 at opposite sides thereof and an integral pivot pin 7b spanned between the legs. The pivot pin 7b preferably includes a rounded surface at least in its lower portion thereby facilitating the pivotal movement of the second plate member 2, as illustrated. The receiving element 8 comprises a traversely extending groove 8 provided with a rounded inner surface, which engages the pivot pin 7b of the pivotal element 7 thereby providing the pivotal connection of the plate members.

In FIG. 5 found is a variaton of the groove 8 as shown in FIG. 4, which comprises a pair of longitudinally spaced and traversely extending

ridges

8a, 8a and a channel 8b defined therebetween.

FIGS. 7-12 illustrate modified embodiments of the pivotal element and the receiving element according to the invention.

Referring first to FIG. 7, a pivotal element 27 comprises a pair of

legs

27a, 27a which have the same structure as those shown in FIG. 3 and pins 27b 2711 traversely extending from the legs opposedly to each other to form a cut-off portion 270 therebetween. The receiving element 28 is provided with two grooves 28a 28a formed in the outer surface of the second plate member 2 at opposite sides, these grooves being adapted to engage with said pin 27b 27b respectively. In this case, the two grooves 28a 28a may be replaced by the same single groove as that shown in FIG. 6.

A pivotal element 37 as shown in FIG. 8 is similar to the element shown in FIG. 3 with the exception that a pin 27b is provided at its central position with a generally semi-spherical pivot 37d which projects toward the outer surface of the second plate member 2 the semispherical pivot 37d serves as a receiving element by engaging with a recess 38 having an inner surface shaped in correspondence with the shape of the pivot, thereby providing the pivotal connection of the plate members.

FIG. 10 illustrates variations of the pivot and the recess in FIG. 9 in which a pivot 47d is in the shape of a half-disk and a recess has a inner surface shaped substantially in correspondence with the shape of the pivot 47d.

A pivotal element 57 as shown in FIG. 11 and FIG. 12 is similar to that shown in FIG. 8 with the exception that a pivot 57d of the element is in the shape of an egg or a ball. A receiving element 58 illustrated comprises a pair of traversely spaced-apart egg or ball-

shaped elements

18a, 18a which are integrally formed on the outer surface of the second plate member 2, wherein the pivot 57d should be positioned in the rearward of the pair of

elements

18a, 18a. The egg or ball shap'ed pivot 57d engages with the pair of

elements

18a, 18a to provide the pivotal connection of the plate members.

The pivotal element and the receiving element of the invention ar Breferably moulded of Plastic materials, respectively, 't@gther with the fif'si plate member and the second plate friember. I-IowEVf; hch pivotal element formed integrall with the plastic plate member may be in the form of a metallic gate arm 67 as shown in FIG. 12. Such a metallic arm will be integrated with the plate member in the stage of the moulding.

Disposed between the first and second plate members l, 2, is a spring 8 for biasing the

jaws

3, 4 to the opened position. The spring 8 is a generally V shaped compression spring of a steel strip, as shown in FIG. 14. One end of the spring is fitted in a groove 9 formed in the inner surface of the first plate member 1, and the other end is fitted in a groove 10 formed in the inner face of the second plate member 2.

Movably mounted adjacent to the rear end of the second plate member 2 is a closing member 11 which is movable between a first position (see FIG. 2) in which it holds the rear ends of the

plate members

1, 2 apart from each other and fore ends or

jaws

3, 4 together against the force of the spring 8 and a second position (see FIG. 1) in which the closing member permits the rear ends of the plate members to move toward each other to separate the jaws.

The closing member 11 which is formed of moulded plastic materials, is generally L-shaped and includes a tail portion 11A and a clip-engaging portion 118 extending generally perpendicularly to the tail portion. Further, the closing member is provided with a central openings 12 (see FIG. through which the rear end of the second plate member 2 extends when the closing member is in the second position as shown in FIG. 1.

The tail portion 11A of the closing member 11 is provided with a slit 13 for securing the clip A to a belt or strap generally designated by the reference B. The slit 13 is spaced from the central opening 12 as illustrated in FIG. 7. Moreover, the tail portion may be provided with a cut-off portion 13a communicated to the slit for facilitating fitting of the belt into the slit.

The first plate member 1 includes a stop element 14 extending from the rear end thereof toward the rear end of the second plate member 2. The stop element 14 is engageable with the tail portion 11A when the closing member is in the first position.

The clip-engaging portion 11B includes a pair of

projections

15, 16 extending generally perpendicularly to the tail portion 11A. When the closing member 11 is in the first position, one projection 15 fits in a recess 17 formed in the first plate member 1 while the other pro jection 16 fits in a recess 18 formed in the second plate member 2, thereby holding the rear ends of the plate members apart from each other. The

projections

15, 16 are extended between the plate members generally parallel therewith when the closing member is in the second position. Thus, in use, the clip is perfectly locked in the closed position for gripping, whereby an article fitted between the jaws is prevented from slipping off from the jaws even if the tention of the belt or strap is considerably high.

As illustrated in FIG. 17, a pair of

lugs

19, 20 may be provided on the second plate member 2 so as not to readily disengage from the first plate member 1.

Such lugs

19, 20 are adapted to be disposed inside the pivot element of the first plate member. In other words, the

lugs

19, 20 act as means for preventing the first plate member from disengaging and rolling, and consequently differ essentially from the conventional lugs for a pivot.

AS stated above, the pivotal element 7 and receiving element 8 for providing the pivotal connection are very simple in configuration, and therefore the manufacture and assembly of the clip are extremely easy and thus the cost of manufacture is low. Moreover, the function of the pivotal element 7 and the receiving element 8 compares quite well with that of the conventional pivotal connecting members.
