Definitions

• Removable clip for paper clips, paperclip type, and dispenser Removable clip for paper clips, paperclip type, and dispenser.
• the invention relates to stationery articles for separably binding overlapping sheets of paper; these items are commonly known as paper clips.
• the paper clips have, in known manner, a threadlike structure whose planar profile comprises an external element and an internal element. These two elements are connected by one side to form a kind of hinge which allows them to flex relative to each other outside the plane in which they are at rest.
• the paper clip is placed by forced deformation thereof, so that these two elements are placed on either side of the superimposed sheets of paper.
• the retention of these is ensured by the elastic return action of these two elements towards their rest position, an action which generally slightly deforms the sheets and which creates a high holding friction.
• these paper clips have the disadvantage of being inconvenient to handle and set up.
• the main object of the invention is to provide a removable fastener of the kind in question which does not have this drawback.
• the fastener according to the invention is characterized in that it comprises a first elongated element forming a frame, a second elongated element, located inside the outline of the frame and attached to the latter on a small side of its outline, the fastener being in the form of a rosary, ribbon or strip of fasteners aligned in the same plane and connected together by their short sides, along lines of weakness.
• the fastener according to the invention is made of injected plastic
• the frame is of rectangular external shape
• the inner element is constituted by an elongated solid blade or tongue connected to the frame by a short side.

• the use of the bar 4 according to fig. 1 to 3 or 7 and 8 is as follows.
• the user grasps the entire bar, or what remains of it, to present the first fastener to the stack of sheets of paper; the bar is oriented so that this first fastener has its tongue 2 at the rear; in the drawings, the first attachment is the one on the left.
• the other fasteners of the bar held in the palm of the user, provide a good grip and facilitate maneuvering.
• the bending of the bar, in conjunction with a support on the tongue 2 of the first fastener allows this tongue to move apart for the introduction of the sheets of paper.
• the clip is in place, simply hold the first clip separately, holding the sheets, and the rest of the strip, then give a bending movement so that the zone or zones break in the zone of line 6.
• the maneuver and the presentation of the bars 4 can be facilitated if, according to another characteristic of the invention, use is made of a distributor or magazine 7 which is intended to receive several bars and from which the fasteners can be individually subject to the stack of sheets of paper.
• the dispenser is of the drawer type. It has an outer casing 22 in the form of a flat rectangular parallelepiped and an inner drawer 23.
• the envelope 22 is for example made of stainless steel, facilitating screen printing. It has a top 24, two side walls 25, a rear wall 26 and a bottom wall 27 formed by the two folded lower edges of the side walls 25, these edges serving as slides for the drawer 23.
• the casing 22 has a notch 28 which extends over the entire width of the dispenser.
• the front face of the envelope 22 is completely open to allow the slide 23 to slide.
• the drawer 23 is made for example by thermoforming from a plastic sheet. It has over its entire width adjacent longitudinal channels 29 which extend over practically the entire length of the dispenser and which are separated by ribs 30. At the front, the drawer has a transverse wall 31 perpendicular to the channels 29 to define a extreme front cavity 32 for handling the fasteners.
• the channels have two ascending lateral ramps 33 intended to support the long sides of frame 1 of the first fastener. These ramps slightly raise the first fastener and press it against the upper face 24 of the casing 22 to ensure the retention of this fastener by friction.
• Each channel 29 receives a bar 4 by threading it to the bottom of the channel. To separate a fastener for its use, it suffices to slide the bar of one of the channels outwards over a length equal to that of a fastener and to break the tabs 5 according to the movement indicated above. The first fastener separates and the second, which then becomes the first, remains held in place by friction.
• the bars are arranged in the channels so that, for each fastener, the short side 21 is behind, which facilitates the positioning of the fastener on the sheets of paper after its separation.
• This dispenser is in the form of an elongated parallelepipedic box.
• the housing has two open ends 8, 9 .
• the wall 13 is located in the center and extends over a third of the length of the housing while the two wall parts 14 are located at the ends and each also occupy a third of the length of the housing.
• the open end 9 is used for the introduction of the bars 4.
• the rear rear edges of the walls 11, 12 have a ratchet tooth profile 15 oriented in the direction of penetration of the bars.
• the distance between the teeth 15 is slightly less than the width of the bars.
• the rear end of the walls 11, 12 must therefore flex for the penetration of the bars.
• the corresponding part 14 is not not linked over its entire length to the walls 11, 12, but there remains a free zone 16 allowing this bending.
• the open end 8 is used to exit the fasteners. Its edges have a profile 17 in the form of a ratchet tooth oriented in the direction of exit. The distance between the teeth 17 is less than the width of the fasteners, so that the teeth 17 can penetrate the area of the bar left free, between two successive fasteners, by the connecting part 5.
• the wall part 14 is not linked over its entire length to the walls 11, 12, but there remains a free area 18 allowing the ends of the walls 11, 12 to flex for the passage of a fastener by its total width.
• the inner faces of the walls 11, 12 carry bosses 19, separated transversely from the width of the fasteners, to guide the bars.
• the distributor is loaded through the end 9 by threading the bars 4 individually or together.
• the first bar is advan ⁇ ERC hand so that only emerges the first fastener on the back retained by the teeth 17.
• the distributor 7 is held in the palm of the hand and a good grip for the user.
• the distributor facilitates the storage of the fasteners; it advantageously constitutes a means of counting the fasteners and can serve as a desk rule.
• the distributor 7 can be produced by injection, without requiring a mold with moving parts.
• the fastener 10 and the bar 4 are advantageously made of plastic and also produced by injection. They can also be produced by stamping from a sheet metal, for example based on aluminum.
• the bar, strip or chain 4 can, in particular according to its manufacturing method, for example stamping or injection, be made of elements of uniform length or on the contrary continuously. In the latter case, the resulting product is either cut later to give bars of the same length, to be used in the above dispenser, or kept in great length to be presented in the form of a reel to be used with a dispenser by unwinding.
