Definitions
- Magnetic key cards such as described in Sedley U.S. Patent No. 4,077,242 "Metal Magnetic Key” require a substantial amount of magnetic energy to encode discrete magnetic areas in specific locations to operate card locks that utilize magnetic pin tumblers to form the code of the lock, for example, the "Magnetic Key Operated Door Lock” as described in Sedley U.S. Patent No. 4,133,194.
- the method that has been utilized for many years is an electronic device such as described in Sedley U.S. Patent No. 4,128,851 "Hand Held Magnetic Encoder.”
- Neodymium which has very strong magnetic properties
- the polarity of the magnetic area created on the key can be either North or South, depending on which end of the magnet was used to create the magnetized area on the key.
- the advantage of using a device that can encode magnetic keys in this manner is that electric power does not have to be utilized for the encoding device, and the parts which often fail in those devices such as the electric switches that turn on the device or change its polarity are no longer a source of faulty encoding.
- the electric encoding device is battery operated there has always been the problem that when the batteries become weak so does the resulting magnetic area on the key, and the person doing the encoding may not be aware that the code is not of sufficient strength, and the person to whom the key is issued is not able to unlock the lock using that key.
- a coding fixture such as described in the Sedley '851 patent is normally used into which the key to be encoded is manually placed behind a plate pierced with holes at the exact location where magnetic areas could be applied to the inserted key.
- the holes are sized to accept the tip of the encoding device which, when energized by the electronic circuit inside the device, creates a strong magnetic field of either North or South polarity which is transferred into the key at the location of the selected hole.
- a code template is first created which is a paper or plastic sheet on which is printed the pattern of the complete array of magnetic areas that could be encoded on a key for a particular type of magnetic lock or locks. Typically specific holes are punched out of this code template with a hole punch or other tool.
- a hole punch or other tool In a preferred embodiment of such a code template, there are two identical array fields printed on the card side-by-side. The hole locations are numbered to identify which pin tumbler in the lock would be affected by a magnetic area of the key when said key is inserted into the card lock.
- one of the arrays of numbers is for encoding all the North magnetic areas and the other is used for encoding all the South areas.
- Using two separate areas reduces the potential error if both polarities were punched into one array and the person doing the encoding had to change the polarity while selecting holes in the card to be coded. Also it is easier to miss one or more holes while encoding in this way.
- Another purpose of the invention is to combine into one device the permanent magnet tools used to encode the key and the code fixture into which the key to be coded is inserted.
- a device or fixture for magnetically coding a card key includes a front plate with an area for North magnetic polarity coding and an area for South magnetic encoding, and each with a relatively large number of holes, a code template having a smaller number of holes corresponding to selected holes in the front plate and attachable to the front plate, and North and South permanent magnet encoding tools sized to be inserted into the holes in the code template and front plate.
- the device further includes a card key holder moveably connected to the fixture for placing the card key proximate the North or South portion of the front plate.
- the fixture further preferably includes a magnetic encoding tool holder connected to the device for storing the permanent magnetic encoding tools when not in use, and the tool holder includes a magnet to attract and retain the encoding tools.
- the card key holder and the encoding tool holder are coupled together and slidably connected to the fixture.
- the North encoding tool protrudes out from the fixture for easy access, and such that when the card key holder is proximate the South portion of the front plate the South encoding tool protrudes out from the fixture for easy access.
- the encoding tools are color coded, e.g., blue for North polarity and red for South polarity.
- the fixture also includes a base plate located behind the front plate that is one color (e.g. blue) behind the holes in the North portion of the front plate and a different color (e.g. red) behind the holes in the South portion of the front plate.
- the fixture also preferably includes a clip connected to the device for attaching the code template to the front plate, and the clip in combination with the base plate functions as a stand to keep the fixture upright.

- code fixture device 10 tool holder or hollow tube 12 holder internal magnets 13 permanent magnet encoding tools 14, 16 color stripes on encoding tools 15, 17 sliding card holder section or slider 18 angle brackets 19, 21 card key 20 code template 22 front plate 24 registration pins 26 spring clip 28 retaining arms 30 base plate 32 code template holes 34 base plate holes 36
- the code fixture device 10 includes a tool holder in the form of a hollow tube 12 for the two permanent magnet encoding tools 14, 16, which has been fitted with a permanent magnet 13 in its center so when the correct tool 14 or 16 is inserted in the tube 12 it is attracted to the internal magnet 13 and is retained in position. If the wrong tool 14 or 16 is inserted it is repelled by the internal magnet 13. In this manner it is only possible to place the tools 14, 16 in their respective tube 12 ends after use and for storage.
- the internal magnet 13 also serves as a "keeper" for the tools 14, 16 and tends to retain their magnetic strength.
- the tube 12 with inserted tools 14, 16 is fixed to the sliding card holder section 18 of the code fixture 10 into which the key 20 is inserted for the purpose of encoding. Pulling or pushing horizontally on the tube 12 moves the slider 18 to either side of the code fixture 10 for the purpose of positioning it properly for encoding either polarity of magnetic areas (e.g., FIGS. 5, 10). There is also a center position between the North and South locations where the slider 18 is placed to load and unload the key 20 and when the fixture 10 is not in use (e.g. FIGS. 3, 14). Note at the center position the tools 14, 16 do not protrude past the sides of the fixture 10.
- Securing the tube 12 to the sliding member 18 has the additional benefit that the proper tool 14 or 16 is extended outside the edge of the fixture 10 and is easy for the person doing the encoding to pull it out of the fixed tube 12 for use to encode the hole array on that side of the of the code template 22 (FIG. 5).
- the sliding member 18 carrying the inserted key 20 can be pushed horizontally across the fixture 10 to the corresponding position on the opposite side of the fixture 10 where the magnet tool 14 or 16 for that polarity of encoding is extended for easy withdrawal from the tube 12 and available for replacement into the tube 12 when the encoding of that side has been completed (FIGS. 9-13).
- the front plate 24 also includes a pair of angle brackets 19, 21 (FIGS.
- encoding is done by simply touching the tip end of the magnetic tool 14 or 16 to the surface of the key 20 through a hole 34 in the code template 22 and the corresponding aligned hole 36 in the plate 24 that covers the key 20 in the fixture 10 (FIGS. 8, 12).
- Other hole 36 pattern front plates 24 can be installed on the code fixture 10 without any other change to the fixture 10, so that keys 20 using other array position of magnet areas can be encoded by the same fixture 10 by simply changing the front plate 24 containing the two arrays of holes.
- registration pins 26 in the fixture 10 are positioned in corresponding holes in the code template 22 prior to encoding each array. It has been necessary in the past to hold the code template on the surface of the code fixture 10 or it could fall off during the encoding process.
- the spring clip 28 that holds the code template 22 in place is situated across the bottom of the front of the code fixture 10 and by pressing the clip 28 with a thumb the retaining arms 30 move away from the surface of the fixture 10 so that the code template can be inserted and positioned over the registration pins.
- the clip 28 is released its arms 30 contact the code template 22 and hold it on the surface 24 of the fixture 10 during the encoding process.
- the clip 28 is again opened and the code template 22 removed (FIGS. 15, 16).
- the clip 28 is pivoted so as to open when the outside plate of the clip 28 is pressed and a spring biases the clip 28 shut when not opened.
- the bottom edge of the clip 28 is positioned forward of the code fixture 10 base plate 32 and provides means to stand the entire code fixture 10 upright on a table when not in use to conserve table top space (FIG. 2).
- the base plate 32 behind the holes 36 is painted blue on the North side and red on the South side, so if no key 20 is inserted the blue or red colors show through the holes 36 and show that there is no key 20 at that location. This helps to prevent the situation where the person doing the coding forgets to slide the card 20 to the opposite side and encodes empty holes 36 in the code fixture 10. If either the blue or red color shows through the holes 34 in the code template 22 there is no key 20 in that position and that side should not be coded.
- the three positions of the slider carrier 18, center, North and South are defined by ball detents (not shown) in the carrier 18. Thus when in any of the three positions, the slider 18 is accurately held in position and will not move from that position until pushed to one of the other positions.
- FIGS. 4-17 show the sequence of steps in mechanically encoding the magnetic card in accordance with the present invention.
- a code template 22 is inserted into the fixture 10 in front of the front plate 24 and located by the two (2) registration pins 26 and held in place by the clip 28 (FIG. 6), and a card key 20 is inserted into the sliding holder 18 (FIG. 4).
- the combination card holder 18 and tool holder 18 is slid to one side such that the blue-coded North tool 15 protrudes past the edge of the base plate 32 for easy access of the correct tool 15 (FIGS. 5, 7).
- the tool 14 is removed from the tool holder 12 and placed through the holes 34 in the code template 22 (and the front plate 24) to contact the card key 20 and magnetically encode it, this step repeated for each of the holes 34 in the template 22 (FIG. 8). Note at this position the key 20 is retained in the sliding holder 18 by the angled bracket 19 (FIG. 9).
- the tool 14 is replaced in the holder 12 and slid across the fixture to the other side (FIGS. 9, 10).
- the key 20 is retained by the other angled bracket 21 (FIGS. 10, 11).
- the red-coded 17 South tool 16 is removed and used to complete coding of the key 20 (FIGS. 11, 12).
- the South tool 16 is replaced and the holder 12 slid back to the center position (FIGS. 13, 14).
- the three retaining arms 30 of the clip 28 may be opened and the template 22 removed (FIGS. 15, 16), and the coded card key 20 removed clear of the angled brackets 19, 21 (FIG. 17).
