The invention relates to a storage and retrieval device for paper clasping and binding mechanisms.
Currently there are a number of different clipping and clasping devices of various sizes, shapes and uses available to the public, such as binder clips, magnetic clips, workbench clamps, hemostats, wire clamps, lapel clamps for name tags, clothes pins, and many others. Binder clips and paper clips are normally transported in small boxes or plastic containers, like many other office supplies. Clip holders have included circular vessels made from stamped metal or wire mesh, and these clip holders can be stacked on top of each other to conserve space on an office desk.
Magnetic binder and paper clip holders have also been produced that possess an aperture surrounded by magnetic elements. These types of holders may be shaped in a box, tray or cylinder design, and apertures can be placed in a circular, triangular or rectangular shapes on the holder body. Magnetic elements can surround the opening or an aperture on the container, which assists in keeping the clips organized and more accessible to the office worker.
Many of these containers are composed of multiple parts, including a body structure and a lid or top portion of the container. These multiple part containers are cumbersome, and sometimes these multiple parts of the container come apart when paper and binder clips are accessed in the container. What is needed is a single body modular clip holder than does not possess multiple parts or the need for expensive magnetic elements.
The existing containers often present the paper and binder clips in an unorganized fashion grouped all together in a mass of intertwined clips, which makes it difficult to access a single clip when it is needed by the user. Binder clips generally have a gripping end and handle or lever means for causing the gripping end to grasp or release a work piece. The user actuates gripping of the binder clip by exerting pressure on handles or levers to cause either a clasping or releasing reaction of the gripping end.
When binder and paper clips are massed together in an unorganized fashion, they often get tangled together. Storage of binder clip mechanisms in a neat and convenient manner can be challenging due to the size and shape of said mechanisms, and there is a need to present paper and binder clips to the user in an organized and segregated fashion with the grasping portions of the binder clips being easily accessible.
In the present invention, the storage and retrieval device holds paper and binder clip devices and comprises a cluster of extended plastic posts protruding outwardly from a base surface in such a manner to allow a binder clip to grip one or more of the extended plastic posts quickly and easily, without the necessity of the user selecting any particular post or position on the container. Moreover, the storage and retrieval device has a reservoir or well that holds paper clips, clips, or other assorted items (e.g. coins, tokens, etc.).
The cluster format for the extended plastic posts may include any number of extended posts spaced relatively equidistant from one another. Moreover, the number of extended plastic posts should be sufficient to allow for storage of a sufficient number of the binder clips such that the storage device will prove efficient in the context of use.
The extended plastic posts may include a two stage structure where the lower portion of the post has a predetermined diameter, and the upper portion of the post has a diameter much less than the predetermined diameter. The post is topped with a semi-circular end for ease of use, and the shape of the extended post may be circular, rectangular, square, octagonal, or any other geometric shape so long as the thickness of the post and shape allow it to stand upright under normal conditions, and to withstand the stress of being gripped by the binder clip mechanism without breaking. The extended plastic posts should be long enough to permit easy gripping by the binder clip mechanism.
Generally, the extended plastic posts are made of flexible material, but the need for, or degree of; flexibility will depend upon the type of binder clip mechanism for which the particular storage device is designed. In a preferred embodiment, the base surface from which the extended plastic posts protrude is planar, but the surface could have a nonplanar contour such as hemispherical, pyramidical, or with other geometric shapes or designs that permit the extended plastic posts to protrude upward and/or outward for access by the user. The surface may also be circular, spherical, egg shaped, cylindrical or otherwise designed to employ a 360 degree user field that would turn on an axis so that all 360 degrees could be accessed by the user.
For a more complete understanding of the present invention, and for further details and advantages thereof, reference is now made to the following Detailed Description taken in conjunction with the accompanying drawings, in which:
The present invention is directed to a system and method of making a storage and retrieval device for various binder and paper clip devices, as well as other items. These clip devices range from binder clips, magnetic clips, work bench clamps, hemostats, wire clamps, lapel clamps for name tags, close pin clamps and the like. The present invention is fabricated with a high-density plastic composition. In order to make the present invention, the manufacturer will need high density liquid plastic, a heat source and heating vessel, a thermometer, coloring, a mold configured to imitate the shape and size of the storage and retrieval device.

To provide additional strength, a fillet 132 may be integral with the device at the junction between the post base 126 and the base 120 (as best shown in
With regard to the dimensions of the present invention, in one form of the invention, the base has a dimension of 106 mm by 152 mm. The extended plastic posts are positioned in a matrix of ten extended plastic posts by sixteen extended plastic posts with a spacing between extended plastic posts of 7.5 mm. Post spacing may be adjusted as necessary. Each post is 17 mm in length from the base connection to the hemispherical tip and is filleted at the base for additional strength. The fillet has a radius of 1.4 mm. The diameter of the pin just above the fillet is 7.6 mm and gradually tapers to 6 mm as it transitions into the hemispherical tip. There is a step reduction in the diameter of the base. The thickness of base is 6.5 mm and may be honeycombed to reduce the material required for construction.
Although a preferred embodiment provides for the equal distance spacing of extended plastic posts 124, equal distance positioning of the extended plastic posts is not essential to the proper operation of the present invention. Moreover, the number of extended plastic posts may be increased or decreased to provide for sufficient storage of an appropriate number of binder clip mechanisms such that the storage device proves sufficient for the use intended. No specific number or orientation of extended plastic posts is essential to the operation of the present invention.
Recess portion 107 of the storage and retrieval device is located laterally of post portion 105, and is configured in a unitary single molded construction for both the recess portion 107 and the post portion 105. Recess portion 107 comprises a large recess, reservoir or indentation 130 extending down into base 120 from upper base surface 122. Recess 130 is preferably deep enough to hold paper clips, coins, tokens, while still allowing sufficient thickness of the base 120 under the recess 130.
The surface of the recess 130 may be dimpled or textured to allow for easier pick up of small and/or flat items placed within recess 130. Additionally, a fillet may be integral with the recess 130 edges to also allow for easier pick up of small and/or flat items within recess 130 as the fillets would help push the items up when the items are slid towards and make contact with the fillets. Optionally, the storage and retrieval device may comprise lettering, symbols, or designs imprinted, embossed, debossed, or etched preferably along an outer edge of base 120 or along the lower surface of recess 130.
For illustrative purposes,
In one form of the invention, the material used for the extended plastic posts has a durometer between Shore A 45 and Shore A 60. A durometer of Shore A 60 has been found to be appropriate for the present invention. A high tear resistance is also preferred. Use of materials having a tear resistance over 100 P.l. is preferred. Having such a high tear resistance assists in providing a product wherein the extended plastic posts will not be torn or otherwise separated from the base when binder clip mechanisms, such as binder clips, are removed from the extended plastic posts.
The material used also should have a minimal compression set. A low compression set assures that the binder clip mechanisms do not leave compression indentions or marks on the extended plastic posts when binder clips are removed. Also, use of materials having a minimal compression set will provide extended plastic posts having resilience to retain their original shape even after being crimped or bent for long periods of time.
Although many materials will meet the requirements necessary to implementation of the present invention, plastic such as flexible thermoplastic polyurethane or polyvinyl chloride (PVC) as well as many rubbers will provide an appropriate material.
The steps in the manufacturing process include several steps. As Step 1, the plastic composition used to make the single molded unit should be mixed and combined thoroughly. The plastic composition must be thoroughly blended into a homogeneous mixture without separations of the material by settling or other means. This plastic composition is heated in a vessel over a low heat from 250-350° F. with frequent stirring or agitation. The plastic composition is a thermoplastic composition which changes its solidity characteristics with heat, but thermosetting plastic could also be used to set once upon heating and cooling. The plastic composition will become clear as it heats. Remove the vessel from the heat source with the plastic composition reaches 325-350° F.
The heat source can be a gas burner, electric heating element, or even a microwave oven. If the plastic composition is heated using a stove top or a melting pot, the mixture should be stirred constantly to prevent burning. Some heating pots may have an integrated heating element.
One can also use a microwave, but a safety measuring cup or safety glass/porcelain ware to heat the plastic composition. If you use a microwave, fill your measuring cup with about ½ cup of mixed liquid plastic. Heat for approximately 1 minute, and then stir the heated mixture. Apply another cycle of heat, and then stir again. Repeat until plastic becomes clear and thick (like syrup) Microwaves vary in power, we have found 1-3 minutes is average for this amount of soft plastic.
In step 2, the mixture should have coloring added to the base plastic mix. Coloring can be added into the hot plastic composition until the plastic has reached your desired color and shade. Coloring should be highly concentrated pigment and can color up to ½ gallon of plastic when mixed to a proper concentration. Coloring can be added with a dropper at this stage in the processing.
In Step 3, the colored plastic composition is injected or otherwise placed in the mold body. The plastic mixture can be placed in a glass measuring cup or fill container beforehand, if needed. Molds can be made of metal or clay, which are fabricated separately, and an impression of the storage and retrieval device is placed in the mold material. Storage and retrieval device molds can be one piece injection molds or two piece molds that produce three dimensional fully formed storage and retrieval devices. The molds are virtually unbreakable and feature built-in alignment pins for easy assembly.
An injector of the plastic material is used to force the hot plastic into the mold. Its reservoir is large enough to make several baits from one filling. Place the mold on the injector with the nozzle in the smaller injection gate of the mold. Holding the mold firmly with both hands, apply slow downward pressure until the soft plastic fills the mold and the overflow reservoir at the top of the mold. Two cavity molds need a short cooling period before filling the second cavity. Set the mold aside for a few seconds and fill another mold while you wait for the first cavity to cool.
You should have enough plastic to make approximately 20-30 storage and retrieval devices. The plastic composition will shrink as it cools, so one needs to make sure the overflow and fill reservoirs of the mold are full to the top when you inject the mold. Underfilling the mold can causes hollow devices, which is not desired. The liquid plastic composition is scorch resistant hot-melt plastic thermoplastic compositions that can be reheated, allowing you to reuse plastic scraps. A hardener can be added to make harder, tougher devices.
In the final step, one should remove the devices from the molds and place them in cool water until they have cooled completely. The devices in the molds are allowed to cool, and one can remove the mold from the injector and stand the mold upright. The soft plastic should be allowed to cool to a solid consistency. The amount of cooling time will vary based on the size of the device and number of mold cavities. After removal from the mold, one should allow the storage and retrieval devices to cool for three to five minutes.
