Abstract
A pushpin which is readily adaptable for use as a pushpin or a magnet is disclosed. The pushpin includes a first body having opposing surfaces, a pin member extending from the body, and a magnetically susceptible component positioned opposite the pin member on the body. The pushpin also includes a second body having opposing surfaces, an opening, a cavity beginning at the opening and extending into the second body, and a magnetically susceptible component positioned on the second body. The particular pushpin cavity is configured to conceal the pin and at least one of either the magnetically susceptible component on the first body and the magnetically susceptible component on the second body is magnetic. Retention means for retaining the pin when it is inserted into the cavity are also provided within the cavity and include friction applied to the pin by a cavity wall. Lining at least a portion of the cavity with a thermoplastic rubber (TPR) material, or providing a plug of such or similar material within the cavity for piercing by the pin, provides such friction.
Description
- In accordance with 35 U.S.C. 120, this application claims the earlier filing benefit of U.S. Provisional Application Ser. No. 60/818,937, filed on Jul. 6, 2006, the disclosure of which is hereby incorporated by reference.
- The present device relates to pushpins used to secure material such as photos, papers, and the like to a vertical surface. Particularly, the present device relates to magnetic pushpins having multiple uses.
- Pushpins, or thumbtacks as they are more commonly known, are used to secure articles such as drawings, photos, cards, notes and other such documents on a support surface such as a wall, ceiling or a bulletin board. Conventional pushpins have a head and a pin projecting outwardly from the head. The pin has a tip for insertion through the article and into the support surface.
- A drawback of these conventional pushpins is the damage that can be caused when the pin pierces the article, especially photographs, causing a permanent hole. Another problem with the typical pushpin relates to safety. When not in use, the exposed tip of the pushpin can cause painful injury to the hands, feet or other areas of an unwary person. Still another problem with some pushpins is the difficulty in removing such devices from a support surface after they have been firmly inserted.
- One solution provided to address some of these problems is the use of magnetic bulletin boards. The board is configured to resemble a typical bulletin board, but rather than the soft, penetrable surface suitable for pushpins, a metal or magnetic metal surface is provided. A series of small magnets can then be used for posting on the board. Articles may be posted without damage. Pointed ends are unnecessary, which prevents any accidental puncture injuries. And, the magnets are easily slid or lifted off the article when removal is desired.
- However, these magnetic boards are typically several times the weight of the usual bulletin board and far more costly. Further, the small magnets used on magnetic boards provide no benefit where only standard boards are available.
- The present device solves these and other problems associated with prior art devices by providing a pushpin which is readily adaptable to either convention, pushpin and magnetic board, as well as by providing safety and ease of operation features not found in prior art devices.
- There is disclosed herein an improved magnetic pushpin which avoids the disadvantages of prior devices while affording additional structural and operating advantages.
- In a preferred embodiment, a pushpin comprising a first body having first and second opposing surfaces, a pin member extending from the first surface, and a magnetically susceptible component positioned at the second surface, and a second body having first and second opposing surfaces, an opening defined on the first surface, a cavity beginning at the opening and extending into the second body, and a magnetically susceptible component positioned at the second surface, is disclosed. The particular pushpin cavity is configured to conceal the pin and at least one of either the magnetically susceptible component at the second surface of the first body and the magnetically susceptible component at the second surface of the second body is magnetic. It is an aspect of the invention to provide a retention means for retaining the pin when it is inserted into the cavity. In a preferred embodiment, the retention means is within the cavity and comprises friction applied to the pin by a cavity wall. Lining at least a portion of the cavity with a thermoplastic rubber (TPR) material provides such friction.
- These and other aspects of the invention may be understood more readily from the following description and the appended drawings.
- For the purpose of facilitating an understanding of the subject matter sought to be protected, there are illustrated in the accompanying drawings embodiments thereof, from an inspection of which, when considered in connection with the following description, the subject matter sought to be protected, its construction and operation, and many of its advantages should be readily understood and appreciated.
-
FIG. 1 is a side view of an embodiment of the present pushpin invention in a first configuration; -
FIG. 2 is a top view of the embodiment ofFIG. 1 ; -
FIG. 3 is a side view of an embodiment of the present pushpin invention in a second configuration; -
FIG. 4 is a cross-section of an embodiment of the present pushpin invention; -
FIG. 5 is a cross-section of an alternate embodiment of the present pushpin invention showing the two halves separated; and -
FIG. 6 is another cross-section of the embodiment shown inFIG. 5 showing the pin member piercing the membrane in the cavity of the second body. - While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail a preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to embodiments illustrated.
- For purposes of the present application, the following are definitions should be applied for each of the listed terms and phrases, or variations thereof:
- “Magnetically susceptible” refers to a material, for example iron or steel, which has the ability to be attracted by a magnet.
- “Magnetic” refers to a component which is capable of attracting iron, steel, or a magnetically susceptible material.
- “Magnetically connected” or “magnetically connectable” refers to a component which is held or is capable of being held in a position by the attractive forces of a magnet.
- Referring to
FIGS. 1-6 , there is illustrated embodiments of a pushpin, generally designated by thenumeral 10. Thepushpin 10 is comprised of afirst body 12 and asecond body 14, which are attachable to, but independent of one another. In fact, the first andsecond bodies - In the illustrated embodiments of
FIGS. 1-5 , thefirst body 12 includes opposing surfaces, i.e.,first surface 20 andsecond surface 21, and apin member 16 extending from thefirst surface 21. Thepin member 16 is preferably made of metal, but may be constructed from a rigid plastic or other such suitable hard and sturdy material. Thesecond body 14 also includes first and secondopposing surfaces opening 18 defined on thefirst surface 22. Acavity 19 begins at the opening 18 of thefirst surface 22 on thesecond body 14 and extends into thecore 25 of thesecond body 14. - One manner of attaching the two
bodies pin member 16 into thecavity 19. As illustrated in the embodiment ofFIG. 4 , thecavity 19 of thesecond body 14 comprises retention means 26 for retaining thepin member 16 of thefirst body 12 when it is inserted into thecavity 19. The retention means 26 is preferably provided by the use of a thermoplastic rubber (TPR) material lining at least a portion of, and preferably theentire cavity 19 of thesecond body 14. The TPR material is used to such that it contacts the insertedmetal pin member 16 and frictionally retains it within thecavity 19. - Alternatively, a small plug 27 of TPR may be positioned within the cavity, as shown in
FIGS. 5 and 6 . Much like the lining of TPR, the purpose is to engage thepin member 16 and retain it within thecavity 19. However, the plug 27 is intended to be pierced by thepin member 16, as shown inFIG. 6 , with every insertion. The plug 27 is preferably about 1.4 mm thick, though thickness variations are contemplated to suit different needs. - A small detent connection (not shown), such as an annular bump and corresponding recess, may be used in addition to or instead of the TPR material. The concealment of the
pin member 16 in this fashion provides a key safety feature minimizing the risk of accidental injury from an exposed point. This configuration also provides a useful way of keeping the twobodies - A second manner of attaching the two
bodies first body 12 comprises a magneticallysusceptible material 30, such as a steel plate, mounted in thesecond surface 21. Alternatively, a magnet may be mounted within thesecond surface 21 of thefirst body 12. Likewise, thesecond body 14 preferably comprises amagnet 32 mounted within, such that themagnet 32 has a surface substantially flush with thesecond surface 23. Where a magnet is used in thefirst body 12, a magnetically susceptible material may be used in thesecond body 14. Using such configurations enables thesecond surface 21 of thefirst body 12 to be magnetically connected to thesecond surface 23 of thesecond body 14 when the two are brought together. - In use, when the two
bodies FIG. 1 , thepushpin 10 is capable of functioning with a magnetic bulletin board (not shown) or most any other magnetically susceptible surface (not shown) to retain or post an article (not shown). For example, where a magnetic board (i.e., the board is actually implanted with magnets) is used, an article may be sandwiched between the board and either second surface (21 or 23) of the two bodies—these surfaces may comprise a magnet or a magnetically susceptible material. Where posting is to be on a magnetically susceptible surface, such as steel or iron, then the item may be sandwiched between the surface and the magnetic surface of thepushpin 10. - As shown in
FIG. 3 , the second attachment configuration allows thepin member 16 to be used in a known manner. Additionally, by sandwiching an article between the two magneticallyconnectable bodies pin member 16 may also be used to pierce the article, if desired. In the latter use, thesecond body 14 may be used separately on a magnet board as described above. - Naturally, when separated, the two
bodies first body 12 as a traditional pushpin and thesecond body 14 as a magnetic pushpin (or with a magnetic bulletin board). - Another feature of the present invention includes the ease with which the
pin member 10 may be removed from a board. Thefirst body 12 is preferably designed having a substantially frusto-conical shape—i.e., having a circular cross-section with an outwardly tapered sidewall—as shown inFIG. 3 . By gripping thesidewall 34 of thefirst body 12, the inward pressure exerted on thesidewall 34 will be transferred into a force which moves thepin 10 in a direction opposite the pin—i.e., out of the board. This will assist removal of thepushpin 10. Likewise, the hourglass-shape of thesecond body 14 makes gripping and removal of thesecond body 14 equally trouble-free. By coordinating the width of thefirst surfaces bodies FIG. 1 . The same ease of removal is provided when the twobodies - The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of applicants' contribution. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
