A pressing spring 16 formed in a substantially "-shape is interposed between the supporting frame 14 and the body 4 which is in a condition which is always subjected to an acting force of the spring 16 in the counterclockwise direction in FIG. 1, as a fulcrum the shaft 15. Formed in an upper end of the supporting frame 14 is an engaging recess 17 which supports in fitting an engaging member 18 therein (refer to FIGS. 7 and 8). Mounted on the engaging member 18 is one end of a spring type 19 of leaf spring in the form of a belt and the other end of which is wound about an engaging piece 21 provided on a sliding pusher member 20 mentioned hereinafter. The

engaging piece 21 is rotatably and slidably guided in

elongated holes

30 and 30 formed in

side plates

29 and 29 of a further body 28 described hereinafter (refer to FIG. 7). Shown at reference numeral 22 is a housing, for example, made of synthetic resin or the like, which is oppositely disposed to the housing 1 and is so constructed that a body portion of the device not seen from the outside, is in cooperation with the housing I. The housing 22 is formed in a substantially U-shape in section and a clipping portion 23 is entirely provided on an upper end of the housing 22. A clipping piece 25 providing clipping teeth 24 thereon is provided to protrude on both sides of the clipping portion 23 and is adapted to pinch materials 31 to be clipped, such as papers or the like (refer to FIG. 11) in cooperation with clipping teeth 27 of a movable clipping piece 26 described hereinafter.

The body 28 is U-shape in section is received in the housing 22 and is mounted by a clamping screw 32 from outside of the housing 22. Lower portions of the

opposite side plates

29 and 29 of the body 28 are rotatably mounted on the shaft 15 disposed on the

side plates

7 and 7 of the body 4. Upper ends of the

opposite side plates

29 and 29 of the body 28 are closed by an upper side wall plate 33 and is cut away at an end flange 34 in the body 4 side (refer to FIG. 8). In the same Figure, an engaging recess 35 is formed in the lower end of the cutaway portion 34 and therein, is intended to engage and disengage the engaging portion 18. An opening window 36 is formed in a corner of the body 28 at the opposite side to the cutawaway portion 34 (refer to FIGS. 8 and 10) whereby clips 37 are positively pushed out, one by one, by the pusher member 10 and is sent between the clipping portion 23 and the movable clipping piece 26. Opposing expanding

members

38 and 38 are entirely provided on the body 28 at both sides of the opening window 36 and the tip ends of the expanding

members

38 and 38 are bent toward inside (refer to FIG. 10). The bending

portion

39 and 39 are sharply formed toward the direction of tip ends thereof. In consequence, the device is constructed automatically to expand the clips, when they are sent one by one by the

sharp portions

39 and 39.

The aforesaid movable clipping piece 26 is pivotably mounted on a mounting plate 41 by means of a pivot 40 (refer to FIG. 11). The mounting plate 41 is provided on the upper side wall plate 33 of the body 28.

A stopper 42 is entirely provided on a base end of the movable clipping piece 26. The stopper 42 is adapted to hook the pressing roller 13 mounted on the tip end of the pressing plate 12 explained hereinbefore whereby the movable clipping piece 26 is always subjected to an acting force in a direction separate from the fixed clipping piece 25. On the contrary, formed at free end sides of the

opposite clipping pieces

25 and 26 is a relatively large opening 43 through which the materials 31 to be clipped are interposed. The movable clipping piece 26, as shown in FIGS. 3 and 5, is provided with a center cutting portion 44 leaving its base end portion and is formed in a bifurcation shape of free end thereof. Protruding

pieces

45 and 45 providing the clipping teeth 27 at its tip ends are formed on portions positioning on the fixed clipping piece 25 of respective lower surfaces of the bifurcating portions. The fixed clipping portion 23 is formed to be a channel shape when it is seen from the direction of the opening window portion 43 and the teeth 24 are formed at tip ends of both rising pieces. Accordingly, as explained hereinafter. when the movable clipping piece 26 has pinched the materials 31 to be clipped in conjunction with the fixed clipping piece 25 a space portion 43a is formed between both clipping

pieces

25 and 26 in a manner that the clips 37 is pushed out one by one (refer to FIG. 11).

Secondly, a preferred embodiment of the clip 37 for applying to the automatic clip dispenser of the present invention is explained in accordance with FIG. 12 to FIG. 14. A simple substance of the clip 37 is formed in a shape having a substantially U-shaped portion 46 and a horizontal portion 47 and a U-shaped portion 48 by bending one steel wire. Free ends 4621 and 48a of the

U-shaped portion

46 and 48 are positioned at the horizontal portion 47 and the

U-shaped portions

46 and 48 are adapted to coincide with each other. A large number of such clips 37 are pre-accumulated as shown in FIG. 13. Further, as shown in FIG. 13, the clips 37 which have accumulated are joined without completely fixing in a manner that their separation is made in smooth when a pushing force is applied by the pusher member thereto.

Action of the automatic clip dispenser according to the present invention is now explained below. First, to insert the clips 37 in the automatic clip dispenser, the housings 1 and 22 are held to apply the acting force in a direction in which the housings become more distant each other. Thereupon, when the acting force is continuously applied after the engaging recess 35 (refer to FIG. 8) of the body 28 came off from the engaging member 18, free end sides of the housings l and 22 become more distant each other and at the same time the spring 19 rolled in the engaging piece 21 is wound back. If the housings l and 22, however, are separated to open 90 or more than 90, as mentioned above the housing 1 is brought to theposition of the single point chain line as shown in FIG. 1, the sliding pusher 20 providing the engaging piece 21 is guided in the elongated holes and 30 provided in both

side plates

29 and 29 of the body 28 and is brought to the lower end as shown in FIG. 1. Thus, as the housing 1 side of the body 28 is completely opened the accumulated clips 37 in the form shown in FIG. 13 may be received within in the U-shaped recess of the body 28 through the above opening. In this case, the U-shaped portion of the clips 37, of course, are received to face toward the inner deep direction of the V-shaped recess of the body 28. After finishing each process as mentioned above, if the housings I and 22 are brought in a direction in which the housings approach adversely to the aforesaid, the free end sides .of the housings 1 and 22 approach with the aid of the coiling force of the clockwork spring 19 each other and the engaging member 18 again engage with the engaging recesses of the body 28. In this case, because the spring 19 is wound on the engaging piece 21 the sliding pusher 20 displaces in the U- shaped recess of the body 28 from the bottom to the top in FIG. 1 whereby the accumulatedclips 37 are upwardly pushed and the clip 37 in the highest position is positioned at a sending position opposing the expanding

members

38 and 38 adjacent to the opening window 36. The next clip is positioned slightly below so as not to align with the opening window 36.

Now, in case of clipping the materials 31 to be clipped, such as a plurality of papers piled up, with a clip 37, the materials 31 held by a single hand are positioned between the

teeth

24 and 27 in interposing the portion to be clipped thereof through the opening portion 43 between the fixed clipping portion 23 and the movable clipping piece 26. The automatic clip dispenser, also, is held by the other hand and the acting force is applied in a direction in which the housings 1 and 22 approach each other. Then, the pressing roller 13 provided on the tip end of the pressing plate 12 rotatingly moves on the slant surface 49 of the movable clipping piece 26 from the left to the right in FIG. 1 so that the movable clipping piece 26 is rotated in the counterclockwise direction having as a fulcrum the pivot and the clipping teeth 27 are moved toward the clipping teeth 24 of the fixed clipping piece 25. Therefore, the materials 31 are interposed between the clipping

pieces

25 and 26. At the same time, the pusher member 10 moves into the same direction as the pressing plate 12 and the recess 11 in the tip end of the web engages the horizontal portion 47 of the clip 37 so as to push the clip 37 from the left to the right in FIG. 1. The clip 37 separates from the next subjacent clip 37 accumulated throughthe intermediary of the pushing acting force and is sent into the space portion 43a. Upon pushing out, the tip end portion 39 sharply formed on the expanding member 38 enters between the

U-shaped portions

46 and 48 of the clip 37 and gradually expands then to send out as the clip 37 is disposed (refer to FIG. 11). When this expansion attains the desired width the clip 37 enters into the space portion 43a and the material 31 in the gripped condition pinched by the clipping

teeth

24 and 27 are interposed into the expanded portion of the clip 37. Thus, when the pressure by the holding or biasing together of the housings 1 and 22 is fully carried out, the pusher member 10 is fully sent to release the clip 37 in the space portion 43a and the clip positively clips the clipping portion of the materials 31 (refer to FIG. 11 and 14).

As mentioned, after the clip 37 has been supplied into the space portion 430 between the clipping

pieces

25 and 26 and has clipped the materials 31, when the pressure by the holding or biasing together is released the body 4 rotates in the counterclockwise direction having as a fulcrum the shaft 15 with the aid of the elastically acting force of the pressing spring 16 so as to return to the position shown in the full line in FIG. 1 and at the same time the spring 19 is wound up on the engaging piece 21 by the spring force of it and furthermore, the next clip 37 is moved into the sending position by rising of the sliding pusher 20 in FIG. 11. Accordingly, by carrying out the same operation as the aforesaid, the clips 37 are sent one by one and can automatically act the clipping operation of the materials to be clipped.

Further, an explanation is made about a modification of the tension mechanism of the materials to be clipped according to the present invention in connection with FIG. 15 and 16. In this embodiment the explanation is made only to different parts from the aforesaid embodiment and is abbreviated about other parts only by attaching the same numberals as those of the aforesaid embodiment.

A pressing plate 12 made of leaf spring in the form of angle is disposed on a web 10b of a pusher member 10 while keeping a proper distance and a flange portion 12a of the pressing plate 12 is mounted on a body 4. A tip end of the web 12b on the pressing plate 12 is formed in a circular arc shape 13a which is carried on a base end portion of a movable clipping piece 26.

The movable clipping piece 26 has not a stopper as the aforesaid embodiment and is pivotably mounted on a mounting plate 41 by a pivot 40. The mounting plate 41 is provided on an upper side wall plate 33 of a body 28. Wound around the pivot 40 is a spring 50, one end of which engages on a lower surface of the movable clipping piece 26 and the other end of which engages on the upper side wall plate 33 of the body 28, respectively, whereby the movable clipping piece 26 is always subjected to an acting force in a direction displacing it more distantly from a fixed clipping piece 25. On the contrary, formed at free end sides of opposite clipping pieces and 26 is a relatively large opening 43 (refer to FIG. 16) through which the materials 31 are interposed. The explanation of an action of this embodiment abbreviates because of being similar to that of the above mentioned embodiment.

Next, a modification of the clip expanding mechanism is explained in reference to FIGS. 17 and 18, but the explanation of the same members as the aforesaid embodiment abbreviates in attaching the like numerals.

In FIGS. 17 and 18, upper ends of

opposite side plates

29 and 29 of a body 28 are closed by an upper side wall plate 33 and an opening window is formed in a corner of the body 28 as the aforesaid embodiment. Clips 37 are positively sent one by one by the pusher member 10. Integrally provided on the body 28 are opposing

members

38 and 38, tip ends of which are bent toward the inside. A slant protrusion 51 is integrally formed on the body 28 on a U-shaped upper flange of the body 28 positioned at the opening window 36 and an upper flange 52 of the slant protrusion 51 is positioned so that the one portion 48 of the clip 37 can pass between tip ends of

sharp portions

39 and 39 on the expanding

members

38 and 38. Further, a downwardly slant protruding piece 53 is integrally provided at the tip end of the upper side wall plate 33 of the body and a free end of the downwardly slanting protruding piece 53 is positioned at a distance so that one portion 46 of the clip 37 can pass between the

sharp portion

39 and 39 of the expanding

member

38 and 38.

However, in this embodiment the

sharp end portion

39 and 39 of the expanding

members

38 and 38 enter into

portions

46 and 48 of the clip 37 and at the same time because the tip end of the U-shaped portion 48 disposed on the lower side passes over the upper flange 52 of the slant portion 51 provided on the upper flange of the U-shaped portion of the body 28 and the tip end of the U-shaped portion 46 disposed on the upper side of the clip 37 passes under the tip end of the downwardly slanting protruding piece 53, the slanting protrusion 51 and the downwardly slanting protruding piece 53 are adapted to position at the portion of the clip 37, that is, at the inside of the

U-shaped portions

46 and 48. Then, the clip 37 enters into the space portion 43a explained in the aforesaid embodiment when tne expanding of the clip 37 is at a desired width and fits the materials to be clipped in the space, which are in a tensed condition pinched or held by the clipping pieces. Thus, if the pushing of the pusher member 10 is fully effected, a horizontal portion 47 of the clip 37 engaging with the recess 11 of the tip end of the pusher member 10 is sent through the gap between the expanding

members

38 and 38, the slant protrusion 51 and the downwardly slanting protruding piece 53 for positively clipping the materials because the slant protrusion 51 is cut away in the form of slant.

On the contrary, according to the above embodiment, because the engaging portion to the clip 37 of the pusher member 10 is formed in the form of a V-shape or the like shape in section, the V-shaped recess 11 is positively caught in the horizontal portion 47 of the clip 37 so that without occurring the relative sliding phenomenon between the clip and the pusher the positioning is exactly effected whereby the sending of the clip may be smoothly and positively carried out. When the clip, also, is disposed while expanding each portion of the clip to pass between a pair of expanding members and protrusions upwardly and downwardly disposed without any interference, but since the next clips having the clip portion coinciding each other is adapted completely to prevent the sending by the protrusions upwardly and downwardly disposed, it does not cause double sending of the clips. In consequence, the clipping operation may be smoothly and positively effected.

Further, in an embodiment shown in FIG. 19, an upper side wall plate 33 and a body 28 are separately formed and the plate 33 is mounted on upper ends of both sides of the body 28.

Accordingly, action in this embodiment abbreviates its detailed description only by attaching the same numeral to the same member as that of the aforesaid embodiment because it is similar to the aforementioned embodiment.

A further embodiment of the tension mechanism of the materials to clip is next explained in conjunction with FIG. 20.

In FIG. 20, an upper portion of a housing 1 is integrally provided with an actuating member 55 by which a guide space portion 56 is formed at the upper end of the housing 1. An upper end flange 57 of a housing 22 cooperating with the housing 1 is arranged to permit entrance and exit in the guide space portion 56.

The aforesaid actuating member 55 provided on the housing 1 forms a tapered surface 58 on a lower surface of its tip end. This tapered surface 58 is adapted to slide on a roller 59. The roller 59 is pivotably mounted on a mounting plate 41 provided on an upper side wall plate 33 by a pivot 62. On the pivot 62 is wound a spring 63, one end 64 of which is hooked by a stopper piece 65 of the pivoting lever and other end 66 of which is hooked on a movable clipping piece 260 in the form of channel in section. The movable clipping piece 260 is always subjected to an acting force in a direction opposite to the clipping direction by a leaf spring 67 and also the spring 63 is constructed in a manner that a free end flange of the actuating member 55 and the roller 59 maintain a slight gap at the position in FIG. 20 through the intermediary of an adjusting member 68 whereby it is adjusted to reduce idle upon dashing from behind.

Then, after holding material 31 to be clipped in one hand, a portion to be clipped is interposed between a fixed clipping portion 23 and the movable clipping portion 260, that is, into an opening 430 of the housing 22 so as to position on a clipping piece 25. Further, after holding the automatic clip dispenser with the other hand, an acting force is applied to a direction in which the housings 1 and 22 become near each other. Then, the tapered surface 58 of the actuating member 55 provided on the housing 1 strongly pushes the roller 59 and displaces to the right direction while sliding it. For this reason, the movable clipping piece 260 rotates in the clockwise direction as a fulcrum the pivot 62 by an elastically acting force of the spring and both side protruding pieces 450 of the movable clipping piece 260 forcibly contact to the clipping piece 25 of the fixed clipping portion 23. Accordingly, the materials 31 is pinched between the protruding piece 450 of the movable clipping piece 260 and the clipping piece 25 in the tensed condition. At the same time, the pusher member moves in the same direction as the actuating member 55 and the recess 11 of a tip end of the web engages with a horizontal portion of the clip 37 to push out one of the clips 37 toward the right direction. The same action as the aforesaid embodiment is effected to clip the materials 311. According to the aforesaid embodiment, since when the clip is clipped to the materials the tapered surface of the actuating member moves the pivoting lever whereby an acting force of the spring mem ber is adapted to apply to the movable clipping piece, tension holding of the materials located at its clipping position is rapidly and positively effected and clipping is positively effected in spite of difference of thickness in a certain range of the materials to be clipped.

Furthermore, since a pulling force is applied to the sliding roller pushing the accumulated clips by the clockwork type spring the clip is always sent to the sending position on the basis of a uniform pushing force. In consequence, the clipping operation to the materials to be clipped is exactly and smoothly effected.

Since the clips used in each of the aforesaid embodiments are formed of steel wire or the like in the semioblong form having two U-shaped portions substantially coincided each other and one horizontal portion and a large number of clips are accumulated, a simple substance of the clips is not in danger of dispersing them and causing various interferences in their handling and in particular, because the clips are accumulated it is a preferred clip structure for use in the automatic and continuous clipping operation.

Further, although the aforementioned embodiments have been explained with respect to a semi-oblong shape of the clip 37, the shape of the clip used in the present invention is not limited to such a shape, but it may, for example, be in the form of a circular, oval, triangle or the like shape for use and its material can use not only steel wire, but other materials.

According to the present invention, by a simple single hand operation, clips are positively supplied one by one to be expanded, thereby obviating the very troublesome operation of expanding clip by a manual operation. In consequence, according to the present invention, since supplying the clip can be automatically effected, the efficiency of the clipping work sharply increases and further it improves management of business. Furthermore, with the automatic clip dispenser according to the present invention it is possible to clip without opening holes and scratching the materials to be clipped, in spite of the automatic clipping operation utilized.
