    Key attachment system for butterfly type wallet.
    This invention relates to an attachment system to associate a first object, e.g. a key, with a second object, e.g. a key wallet.
    Here, a wallet means a handheld housing for failure keys or similar articles (hereafter commonly called key). A key means here a typical metal article, usually elongated, to be gripped manually and inserted into a key hole of the door or a house or car, for locking and unlocking the door by turning the inserted key clockwise or anti clockwise.
    Prior art key wallets are .: GB877325A, US1187852A, CH596796A5, DE3702505C1, EP1243198A1, US1494242A, US2849044, WO93 / 22948, US2003 / 0226772, US3677044, US2596716.
    The words elastic, resilient, yield, flexible are mainly used to explain that, elastically thus without permanent deformation, the relevant element, eg elongated element, or material can expand in length and / or width, like a rubber or elastic band, or can flex like the free longitudinal end of a rubber rod or a spring steel blade or a cable or twined steel wires or a wire rope, the opposite longitudinal end of which is fixedly clamped similar to a cantilevered beam.
    In the following, the first object is called key and the second object is called key wallet or wallet. Obviously, the first and second object could be different from a key or a key wallet, e.g. be similar articles.
    The object of the invention is versatile and may be one or more of: comfortable to use; operation by a single hand; intuitive operation; safe operation; reliable operation; long life; suited for mass production; environmental friendly; limited number of parts; compact storage and / or transport in large numbers; compact size; tight fit around both a single or a small number and a large number of keys; trousers pocket size; attractive appearance; easy to repair; easy to recycle; protects keys against damage due to keys slamming against each other while carried around in the trouser pocket; avoids the noise or a rattling key bundle; allows storage or oversized, particularly extremely long, keys; allows easy selection of a single key from a key bundle; provides easy access to the stored keys; the key bundle moves easily in and out of the wallet by a simple movement of the user, e.g. his hand or wrist; allows safe storage or a fragile article, e.g. cigarette, in addition to keys; allows one or more keys attached to the wallet to be outside the wallet while the wallet is closed; a wallet size sufficient small to fit in a single hand, e.g. approximately credit card format or format according to ISO 7810, in particular ID-1 or approximately 85 x 55 millimeters; a fit of the keys within the wallet with minimum play or as tightly as possible; an aspect disclosed elsewhere in this application, e.g. in the drawing.
    The object is with by providing that the attachment system is provided by includes an elongated, eg straight, element also called arm which, at a first location along its length, eg its distal end or free tip, is, or can be, mounted to the key, and, at a second location along its length, eg its opposite proximal end, longitudinally remote from the first location, is mounted to the wallet. In the following, the first location is called free tip, the second location is called fixed end and the attachment system is called arm.
    If in the following reference is made to horizontal or vertical or upright or the top edge or the pivot axis or upright side edge of the wallet, the wallet is oriented upright or vertical such that its contents of keys are oriented upright or vertical by gravity action while suspending or hanging from the arm, and / or the pivot axis for opening the wallet is oriented upright or vertical and / or the longest dimension of the wallet is oriented upright or vertical.
    Preferably the design is such that at least one of the following applies: the arm can move, preferably free, eg by virtue of gravity or movement of the wallet, between a retracted position, in which the associated keys, are eg stored within the wallet , and an extended position, eg in which one or more or all of the associated keys are external from the wallet and possibly one or more other associated keys are stored within the wallet; in the extended position the arm projects outside the wallet, preferably at least 50% of its length, more preferably at least almost completely, e.g. at least 80 or 90% of it; in the retracted position the arm is completely within the wallet or not more than 5 or 10% or it is outside the wallet; the wallet is provided with a single arm designed to carry a key; the arm has a fixed length; in the retracted position the arm, preferably the complete arm, extends within the space delimited between two opposing panels of the wallet and / or is sandwiched between two opposing panels of the wallet.
    Preferably moving between the retracted and extended position relates to movement in vertical direction, if the wallet is oriented upright or vertical.
    The arm preferably provides, at its free tip, a suspension point for the keys. This suspension point is, if the arm is in its retracted position, located within the wallet such that, if the closed wallet is oriented upright, the suspension point is located close to the top edge of the wallet and sufficient remote from the opposite upright side edges of the wallet such that the keys are navy stored in the wallet, remote from the opposite upright side and as close as possible to the top edge of the wallet. In this manner the wallet can be designed as small dimensioned as possible without parts of the stored keys projecting outside the wallet. The arm allows to provide the stored keys a centered position within the wallet and / or a position of the grip part or top part of the key as close as possible to the top edge of the wallet for most effective use of the space available within the wallet. The arm also allows to swing the keys between their stored position within the wallet and their operative position outside the wallet.
    The arm preferably extends, in its retracted position, from its to the wallet fixed end such that the suspension point for the keys at the free tip is located: at least 10 or 20 or 30 millimeters and / or not more than 50 or 60 or 100 millimeters from the fixed end; and not more than 10 or 15 or 20 or 25 or 30 millimeters below the top edge of the wallet.
    The arm preferably acts, preferably at least in the retracted position, as an outrigger, eg wall mounted, or like a cantilever or a cantilevered beam or a self-supporting arm or a tree, eg a lifting tree or a davit tree or a wall mounted flag pole or a non-braced cantilever.
    Preferably, if the arm is in its retracted position and the wallet is in its open position and one or more of the wallet, its pivot axis for opening the wallet and the longest dimension of the wallet is oriented upright or vertical, the keys suspend from the arm such that they hang freely within the space delimited by the wallet, only loaded by gravity action while suspending or hanging from the arm (see fig. 6, 15 or 16).
    Preferably for the arm at least one of the following applies: has a stable and / or rigid shape, is e.g. provided by a rod or wire like object to bear compressive and flexural loads at its distal end; has elastic and / or resilient flexibility; has a flexibility comparable to a leaf or leaf spring or length part of a watch-spring; has a length part provided by a spiral spring, e.g. provided by a helically shaped rod or wire; has or covers a length of at least 20 or 30 or 40% and / or not more than 60 or 80% of the width of the wallet; has or covers a length of or the distance between the fixed and free tip is at least 10 or 20 or 30 millimeters and / or less than 50 or 60 or 100 millimeters; has a diameter of at least 0.5 millimeters and / or less than 3 or 4 or 5 millimeters; has a length part or comprises or is made of metal, e.g. steel or stainless steel, preferably spring steel and / or polymer or plastics or rubber or rubber like or elastomeric material; has a length part or comprises or is made of wires, preferably a bundle of wires, e.g. twisted into a cable; is provided with or associated with or designed as attenuating means; is provided at the fixed end with a pivot means to allow for pivoting movement with respect to the wallet; is hingedly attached to the wallet for the movement between the extended and retracted position; the fixed end is attached to the wallet at or near (eg within 3 or 5 or 10 millimeters) the pivot or spine of the wallet for opening the wallet and / or at or near (eg within 3 or 5 or 10 millimeters) the top edge of the wallet; is associated with limiting or stop means, e.g., provided at the wallet to limit moving or pivoting between the retracted and extended position, e.g., to less than 180 or 150 or 140 degrees, preferably allowing pivoting, or at least 45 or 60 or 80 degrees; in the retracted position the arm extends substantially horizontal or parallel to the adjacent wallet edge, eg top edge, or obliquely, preferably downward, into the wallet eg making an angle of at least five degrees and / or less than 10 or 20 or 25 or 30 or 35 or 40 or 45 degrees with the horizontal or the adjacent wallet edge, eg top edge, where the horizontal is related to the upright position of the wallet; is attached to the wallet in such a manner that moving or pivoting is allowed in two mutually perpendicular planes, e.g. horizontal and vertical and / or allows the arm to roll (this means rotation around its longitudinal axis); extends in the retracted position substantially parallel to a, preferably two opposing panels of the wallet; is attached to the wallet by attachment means in such a manner that horizontally moving or pivoting for at least 20 or 30 degrees is allowed, at least in the retracted position; projects from its pivoting mounting to the wallet; is mounted to the wallet at a location between two opposite panels; in its retracted and / or extended position the arm is loosely supported by the relevant stop or limiting means; has, as seen from its mounting location to the wallet, a flexible length part followed by a rigid length part, e.g. at least 50% less flexible compared to the flexible length part, e.g. a wire bundle followed by a metal tube; in the extended position extends parallel to or makes an angle of not more than 5 or 10 or 15 degrees with the vertical; in the extended position is moved or pivoted beyond a position parallel to the vertical; in the extended position the arm has a stable over center position due to the action of gravity forces if the wallet is oriented vertical and the arm is at the wallet top side; provides a key suspension.
    Preferably for the pivot means of the arm at least one of the following applies: comprises a permanent coupling and / or a break coupling, e.g. having a snap fit, for repeated coupling and uncoupling between the arm and the wallet; comprises a design allowing pivoting and / or turning in all directions for an angle of at least 30 or 60 or 90 degrees, e.g. such that the wallet can move angularly freely within an imaginary semi sphere relative to the arm; comprises a ball joint or a living hinge, at the attachment to the wallet; is located completely inside the wallet and / or below the top edge of the wallet.
    In an embodiment the arm holds all or at least two, three, four, five or six keys contained in the wallet, e.g. at a single key retaining element, e.g. loop type element, e.g. wire or ring. Preferably a key retaining element engages the aperture in the grip of the key (the grip means the part of the key which is hero between thumb and indexing finger if the key is inserted in the key hole), and retains the keys. Preferably the arm holds the keys in a removable manner or temporarily such that keys can be added or removed according to desire, and the means for holding the keys are designed accordingly.
    The wallet can be of a type having a rigid or stable shape, eg opposing panels have a mutual fixed position, or is always open, eg as shown in Fig. 16, or of a type of changing shape, eg if opened or closed, eg as shown in fig. 6 or fig. 15. The wallet may be opened and closed repeatedly.
    The invention is preferably applied to a wallet type comprising two shell elements, eg halves (in here also called panels) which are associated by connection means such that they can move relative to one such such a part of the one shell element, eg boundary edge, can move away from the corresponding part of the other shell element to open and close the wallet, eg to provide a V-shape if opened and a II-shape if closed. Preferably this is by pivoting or swiveling or rotating movement of one or both of the shell elements, e.g. around a pivot axis, however a translating movement or the combination of two or more of these movements is also feasible. By way of example, the panels provide the wallet a V-shaped configuration if in the opened position and / or are mutually parallel or provide a II-shape if the wallet is in the closed position.
    The wallet can, by way of example, include a rigid spine (also called hinge or pivot) providing a pivot axis designed for opening and closing it, two shell elements extending from the spine such that they are hingedly connected at the spine,
    e.g. similar to the front and back face of a book, which shell elements have a fixed length and width.
    One or more of the following applies to the wallet: thin walled; shaftless pivot; pivot axis extends along longer side; two mutually pivoting panels, preferably providing opposite main faces; rectangular shape; length at least twice width; thickness (in unloaded, closed condition) not more than 20 or 25% or 50% or 75% of width; thickness (in unloaded, closed condition) at least 5 or 10 and / or not more than 20 or 25 or 30 millimetre; thickness (ie measured from the one to the opposite main wall) or the internal space (in unloaded, closed condition) at least 5 or 10 and / or not more than 20 or 25 or 30 millimeters (the keys, are housed in the internal space); elongated; length at least 50 or 80 or 90 millimeters and / or maximum 110 or 120 millimeters, e.g. approximately 100 millimeters; width at least 30 or 40 millimeters and / or maximum 50 or 60 millimeters, e.g. approximately 45 millimeters; biased to the open position by biasing means, e.g., spring type and preferably also biased to further open, if in the completely open position, further opening is, e.g., blocked by a stop means of the wallet; stop means is integrated in hinge; in the closed position at least one side provides a gap or at least 2 or 3 or 4 or 5 millimeters, preferably one or two sides at the most provides such gap, preferably for substantial or at least 50 or 75% its complete length; a short side or opposite short sides provides the gap; operating button for unlocking the shell halves near or at a corner or midway an edge length and / or at a long or short edge; operating button located between and / or projecting outward from between panels; operating button externally accessible while wallet closed; operating means, e.g. button actuates lock release, preferably provides translating movement or lock part; transmission means associated with operating button to actuate lock; button operated by pushing or turning action, e.g., finger or thumb or user; translating or turning button; opening angle limited to less than 120 or 110 or 100 or 90 or 80 or 70 degrees, preferably by limiting or stop means, e.g. at the pivot; opening angle at least 45 or 60 degrees; lock provides rigid and / or internal locking; lock is provided internal; lock holds opposite edges fixed or rigidly against the open position of the wallet; lock is releasable by releasing means, preferably operated by operating means, e.g., through transmission means; lock provides mutually engaging snapping and / or hooking parts in the closed position; locking parts are provided on both panels, preferably at an outer edge, preferably long edge, preferably midway; in the closed position the shell halves are one or more of: stacked onto each other, located right above each other, parallel to each other, keep the wallet closed; if closed the wallet comprises two external, opposite main faces spaced by its thickness; a releasable lock to selectively keep the wallet closed, preferably or internal type; in closed, unloaded condition and elongated, flat walled, sleeve like shape; the two panels are only mutually connected at the spine; the two panels are mutually connected along one edge and are mutually free along the other three edges; in closed and / or open condition its inside is accessible through three sides and not through the fourth side; the edges at the short minor are only mutually connected at the pivot.
    The wallet preferably is provided by two opposite main faces, two opposite long minor faces and two opposite short minor faces, providing the minor faces provide the wallet thickness. A long minor face meets a short minor face at an angle of 90 degrees. Preferably, if closed, the long minor faces are tight such that they do not allow a key to pass and / or one or both the short minor faces delimit an opening for a key to pass. The arm could be a flexible pulling element, e.g. chain.
    The arm preferably comprises a wire rope. A wire rope is typically produced by twisting helically high tensile wires or strands. Strands are obtained by twisting helically high tensile wires. Twisting is typically done around a core being either a beach or a wire.
    The wire of the arm can be of steel material, possibly galvanized, or stainless steel. Alternative materials are titanium, tantalum, monel, inconel, hasteloy, brass and tinned steel. The wire or strand or rope can be coated, e.g. with a polymer such as polyamid. Wire ropes can be obtained from, e.g., Carl Stahl Technocables GmbH (Germany).
    Preferred arm or wire rope diameters (in millimeters): at least 0.5 or 1.0 and / or not more than 2.5 or 3 or 5, approximately 0.80 or 0.90 or 1.0 or 1.2 or 1.35 or 1.5 or 1.80 or 2.0. Preferred rope: 6x7 WSC or 6x19 WSC (6 beaches twisted around a core, preferably a single strand, each strand contains 7 or 19, respectively, wires). Preferred rope has at least 6 wires, most preferably at least 30 or 35 wires, or at least 6 strands, preferably around a core. Preferred beach has at least 6 wires preferably around a core. Core can be a beach or a single wire.
    By way of alternative to wire or wire rope to provide the arm flexibility, the length part of material different from wire rope, preferably has an elastic flexural rigidity equal to, possibly not more than 10 or 20% different, the wire rope.
    For sufficient flexibility preferably the arm, at its free longitudinal end, diverges at least 2 millimeters and / or not more than 5 or 10 millimeters if loaded by 30 grams of keys (a metal house key typically weighs in the order or 15 grams); and / or at least 0.2 or 0.5 millimeter and / or not more than 1 or 2 millimeter under its own weight, if the opposite longitudinal end is fixedly clamped similar to a cantilevered beam.
    At least the length part of the arm adjacent the fixed end preferably has elastic flexibility to bear the loads generated at the time the movement between the retracted and extended position is stopped at the end of the stroke, e.g. since the stop is engaged. Such elastic flexibility provides an attenuating means to attenuate the loading of the arm at the time the arm is stopped at the end of its stroke. This is an example how the arm can be provided with an attenuating means, e.g. embodied as a length of wire rope or spiral spring or spring steel or different, e.g. elongated, object, preferably integrated in the arm. The arm or other part of the wallet can alternatively be provided with an alternative attenuating means for the same purpose, or by providing the stop with attenuating capacity. To provide the desired elastic flexibility, at least a length part of the arm could be embodied from medium carbon steel or high carbon steel or other material and / or shape as specified elsewhere in this disclosure.
    Preferably, if in the retracted position, the arm acts as a flexural rigid element in the direction of the gravity force and thus as an outrigger for a key loading the arm in the direction of the gravity force. In the opposite direction the arm can be allowed, in an embodiment, to easily flex, comparable to a slap string or rope or chain.
    An alternative designed wallet provided with the inventive arm could be as follows: The panels of the wallet are mutually attached along their longitudinal edges, such that the wallet is a circumferential closed sleeve with open top and bottom. In the disturbing position the opposing panels are close to each other. The operative position is obtained by pushing the longitudinal edges towards each other, such that the opposite panels bulge outward such that the arm and associated keys can now be swung outward.
    Another different designed wallet provided with the inventive arm could be as follows: The wallet has a rigid, right angled, box like shape having an permanently open top and also one of its two narrow sides is permanently open to allow the arm and associated keys to swing outward.
    By way of alternative, the arm could be made from different, longitudinally successive, length parts, e.g. a length wire rope adjacent its joint with the wallet, longitudinally followed by a length metal tube.
    For the wallet one or more of the following preferably applies: including two shell elements, eg halves which are associated by connection means such that they can move relative to one such such a part of the one shell element, eg boundary edge, can move away from the corresponding part of the other shell element to open and close the wallet; including an open position and a closed position, in the closed position providing an elongated sleeve like shape, in the open position the shell elements make a mutual opening angle, the shell elements are only connected to each other along a single edge, also providing a hinged connection providing a rigid spine, in the closed position the inner space of the wallet is open to the environment via two or three of its four edges, which four edges provide a rectangular shape when viewing towards one of the main faces of the wallet, the wallet moves between the open and closed position by pivoting at the spine; the arm carries a bunch of keys and the assembly of arm and bunch of keys is designed to move between the retracted and extended position merely when the wallet is in an open position; provided with a mechanical stop integrated in the hinge to limit the opening angle; a to the arm connected key is absent; having a length between 80 and 120 millimeters, a width between 30 and 60 millimeters and a thickness between 5 and 30 millimeters, if unloaded and closed.
    The attached drawing illustrates presently preferred without limiting the scope of protection, showing in:

    Meaning of the reference signs: wallet 1, key 2, aperture 3 in key grip, operating button 4 or lock, panel providing main face or side 5, key attachment system 6, arm (preferably a rod) 7, linking element 8, key retaining element 9 (eg loop type), pivot axis 11 or wallet, longitudinal edge 12 or the wallet; free tip 13 of the key; adjacent wallet edge 14, stop 15, orientation of the gravity force by arrow G; force arrow F, movement arrow A.
    FIG. 1-5 show the two hingedly connected panels 5, the operating button 4 associated with the lock to keep the wallet 1 closed, and a key attachment system 6 embodied by a key chain providing a closed loop, and extending through the aperture 3 in the grip of a key 2.
    In the closed wallet position, see eg fig. 1, the free or distal longitudinal edges 12 (see eg fig. 11) or the superposed panels (ie the longitudinal edges distal from the pivot axis 11) are near each other while in the open wallet position, see eg fig. 3, these edges 12 are moved away from each other.
    The wallet is provided by two opposite main faces 5, two opposite long sides (having the edges 12) and two opposite short sides (having the edges 14). A long side meets a short side at an angle of 90 degrees. If closed, the long sides are tight such that they do not allow a key to pass, however the short sides delimit an opening for a key to pass such that it can partly project from the wallet, eg if the key is longer than the wallet .
    In fig. 6-12, showing a wallet functionally similar to the wallet shown in fig. 1-5, the key chain has been replaced by the inventive key attachment system 6.
    The system 6 comprises a straight arm 7 connected by a ball joint to the wallet 1 at the one longitudinal end and a linking element 8 (not shown in detail) at the opposite longitudinal end. The arm 7 has sufficient flexural stiffness to remain almost straight in its orientation according to fig.
    while retaining six metal keys or typical household size, however allows for substantial resilient flexing. The linking element 8 is provided with a loop type key retaining element 9 which extends through the aperture 3 in the key grip.
    In Fig. 6 the system 6 is shown in the fully retracted position, in which the arm 7 extends almost horizontally, if the pivot axis 11 extends vertically, such that the keys are located approximately centrally or the space enclosed by the wallet
    1. This orientation of the system 6 is provided by a stop at the pivoting attachment to the wallet. Also, the arm 7 extends parallel to the adjacent wallet edge 14 (the top edge).
    FIG. 6 also shows that the arm 7 extends near and parallel to the left hand panel 5 of the wallet. The pivot at the wallet allows the arm 7, when retracted, both to pivot up and down and also sideways from adjacent the one panel 5 to the opposite panel 5. This provides clean movement between the retracted and extended position.
    FIG. 7 and 8 show in dotted and continuous lines the orientation of the arm 7 in the retracted and different extended positions, projecting outside the wallet. The maximum extended position of the key attachment system 6, is a stable over center position due to the action of gravity forces if the wallet is oriented such that the pivot axis 11 is vertical and the arm is at the wallet top side.
    FIG. 9 shows the wallet closed while the arm 7 projects outside it such that the keys are outside the wallet.
    FIG. 10 shows the arm 7 in its retracted position, sandwiched between the opposite panels 5.
    FIG. 11 shows possible orientations of the arm 7 within the opened wallet, the arm 7 is in its retracted position. The arm 7 can pivot from the one panel 5 to the opposite panel 5, so in the plane of the sheet that bears the drawing, as arrow A illustrates.
    FIG. 12 illustrates a non-straight arm 7, this time having a curved shape. Many different shapes are feasible, e.g. multi angled.
    FIG. 13-14 show an alternative arm 7, provided as an articulated element provided with limited pivoting capability to be straight if retracted and curved if extended. If retracted, the arm 7 acts as a flexural rigid element in the direction of the gravity force G and thus as an outrigger for a key loading the arm 7 in the direction of arrow G. In the opposite direction the arm 7 easily flexes, comparable to a slap string or rope or chain.
    FIG. 15 shows a different designed wallet provided with the inventive arm 7. The panels 5 of the wallet are mutually attached along their longitudinal edges 12, such that the wallet is a circumferential closed sleeve with open top and bottom. In the disturbing position the opposing panels 5 are close to each other. The operative position, which is shown in FIG. 15, is obtained by pushing the longitudinal edges towards each other according to arrows F, such that the panels 5 show outward as arrows A show. The arm 7 and associated keys can now be swung outward.
    FIG. 16 shows another different designed wallet provided with the inventive arm 7. The wallet has a rigid, right angled, box-like shape having a permanently open top and also one of its two narrow sides is permanently open to allow the arm 7 and associated keys to swing outward as arrows A show.
    FIG. 17 shows the fixed end of the arm 7 provided with a pivot means designed as two mutually engaging closed loops which also allows swinging or pivoting vertically and horizontally. Whether the wallet merely the pivot 11 and the top edge 14 or the panels 5 and the stops 15 to limit the upward movement of the arm 7 are illustrated.
    FIG. 18-19 illustrate the arm 7 made from a cable or steel wires. By way of alternative, the arm 7 could be made from different, longitudinally successive, length parts, e.g. a length cable adjacent its joint with the wallet, longitudinally followed by a length metal tube.
    FIG. 20-25 illustrate cross sections or different wire rope designs.

    Many wallet disclosed in here operate as follows: In the closed position, the wallet is a hero in a single hand and the operating button is operated by a finger or said hand to release the lock. Then the wallet is moved to its open position (e.g., Fig. 6). Subsequently, by an adequate wrist movement or said single hand, the arm (7) is pivoted from the retracted to the extended position such that the keys are brought outside the wallet (e.g. e.g. Fig. 8). Subsequently, while the arm (7) remains in its extended position, the wallet is closed by squeezing the shell halves (5) together by action of the fingers or said single hand. After opening the wallet again, the arm can be moved back to its retracted position (e.g., Fig. 6) by an adequate wrist movement.
    The drawing illustrates both panels providing part of the means for hinged connection. Alternatively a living hinge is feasible, or one of the panels provides substantially the hinge, e.g. as a spine. The lock could include magnetic means. Also further alternatives are possible.
    The drawing, the specification and claims contain many features in combination. The skilled person will also consider these individually and combine them to further vary. Also different do not belong to the invention. Features or different in here disclosed in different manners can be combined and different aspects of some features are considered mutually exchangeable. All described or in the drawing disclosed features provide such as in arbitrary combination the subject matter of the invention, also independent from their arrangement in the claims or their referral.
    If the arm is a chain, a wallet panel has a projection (20) at its top edge vertical above the aperture (21) in the key grip (22) (viz. Eg fig. 12) to temporarily support the slack chain in the retracted position, following an L shape.

    Conclusions
    A key file filled with a bunch of at least three flat steel house keys (2) temporarily attached thereto, each for a mechanical cylinder lock, with each key a thickness of the key head and the key bit between 1.5 and 2.5 millimeters, a length between 40 and 60 millimeters, a width between 20 and 30 millimeters and a weight between 15 and 25 grams, which folder can pivot open and closed (11) and when closed provides a thin-walled elongated sleeve with a flat rectangular shape formed by two mutually parallel, flat and rectangular panels (5) with a spacing of at least 10 and at most 20 millimeters of mutually equal dimensions that form the two main surfaces, of mutually equal dimensions, of the sleeve with a length between 90 and 110 millimeters and a width between 40 and 50 millimeters, which panels (5) are fixed to each other only by a single long edge, and in such a way that that nd provides a hinge edge (11), while the panels along the three remaining edges are free from each other, so that the folder can pivot open and closed, the panels (5) in the hinge edge (11) mutually pivoting and the free long edge (12 move the panels towards each other and away from each other;
    the sleeve internally providing the receiving space for the complete key ring and the main faces of the sleeve being mutually connected by long and possibly short sub-faces along the long or short edges of the main faces, which sub-faces determine the thickness of the sleeve and pivot open and closed of the panels (5), which sub-surfaces in the thickness direction of the sleeve all have the same dimensions; which panels are permanently prestressed by biasing means, both in the closed and open pivoted condition of the folder, for automatically pivoting the folder open, wherein the pivoting means further pivots open further and is blocked by a stop element of the folder which has an opening angle of the panels (5) limited to between 60 and 90 degrees; so that the open folder, viewed in the direction parallel to the hinge edge (11), has an appearance similar to a V, the legs of the V being formed by the panels (5), and the open folder being closed by the legs of the V to move towards each other, opposite to the bias;
    if the folder is closed, the sleeve is kept closed along the long edges (12) of the panels (5) by the long sub-faces and the sleeve has a slotted opening over one or both short edges (14) of the panels (5) at least 75% of its length with a width (the dimension in thickness direction of the sleeve) of at least 5 millimeters, due to the complete or partial absence of the relevant short sub-surface, so that a flat key of the bunch, if separate from the folder, with the flat side parallel to the panels can be at least partially slid in and out of the closed folder through the opening at the short edge, or a long key belonging to the bunch of keys with its point (this is the free end (13) through this slot-shaped the opening can protrude out of the closed folder, none of the keys of the bunch cannot move in and out of the closed folder via a long edge;
    the folder is held shut against the action of the biasing means by a releasable latch of the folder, which is operated from the outside by a thumb button (4) located on the outside of the folder;
    the folder contains a key mounting system (6) which provides a mounting point to which the key ring detachably hangs from the key ring / key handle on the folder, which system comprises a single elongate mounting element whose proximal end inside the folder on the hinge edge (11) is attached and whose distal end provides the attachment point; so that the key ring or an individual key can only be attached to the folder by means of the single fastening element and an alternative to the folder for the regular temporary attachment of a key via its hole (3) is missing from the folder;
    of which fastening element a length piece, to which the distal end belongs, can only move with sufficient open folder in (said: retracted position) and out (said: extended position) the folder so that it takes the key ring with it, so that the key ring on the one hand can move are located inside the folder, between the panels (5) or, on the other hand, completely outside the folder, each time hanging at the fixing point provided by the fastening element, wherein, while moving in and out of the folder, the said length piece and the key bunch situated thereon are short (14) pass through the folder;
    the folder being arranged so that it can be closed and held closed both with the length of the fastening element in the retracted position and in the extended position, characterized in that the single fastening element of the folder is arranged to, if in the upright situation of the folder in which the hinge edge (11) is held parallel to the direction of gravity (G), the short edge (14) forms the top edge of the folder and the fixing element is in its retracted position so that the fixing point is located inside the folder and the key ring on it hangs with the key head above the vertically extending key bit;
    provide the attachment point inside the pocket at a reproducible, predetermined and unambiguous position, at a distance of at least 10 millimeters from the proximal end attached to the hinge edge (11), which distance is measured parallel to the short edge ( 14) of the folder, and at a distance of a maximum of 10 millimeters below the short edge (14), which distance is measured parallel to the hinge edge (11), for which purpose the fastening element is designed as a bend-resistant arm (7) in the form of a single rod, the proximal end of which is attached to the hinge edge (11) by pivoting means allowing pivoting at least in the direction parallel to the hinge edge (11) and the distal end providing the single attachment point of the folder, whereby the attachment point is located on a fixed location along the length of the mounting element;
    which arm (7) for the hanging bunch of keys functions as a bending-rigid jib in the form of a single rod that ends at its distal end, because:
    - of the arm is a length part extending from the distal end to the proximal end, a cantilevered length part that is free of a support along its length by the folder and determines at least 75% of the total length of the arm and at least partially overlaps with said length piece;
    - and this longitudinal part of the arm (7) extends perpendicularly, i.e. horizontally, or a maximum of 10 degrees downwardly therefrom, from its proximal end to its distal end, on the hinge edge (11) and extends from its proximal end to its distal end extends along its entire length between the panels (5) and spaced apart from those panels and towards the free long edge (12) of the panels;
    wherein in this retracted position of the arm this length part is held in the aforementioned position and is prevented from pivoting downwards by the force of gravity (G) because the arm rests in the length region between its proximal end and said length part on a first stop (15) ) of the folder that holds the arm from below;
    while the arm, when in its extended position, is prevented from pivoting further parallel to the direction of the hinge edge (11) in the direction from the retracted to the extended position in that the arm supports in the longitudinal region between its proximal end and said longitudinal part against a second stop (15) of the pouch that holds the arm from the side, the first and second stops (15) limiting the pivoting of the arm in this direction to an angle between 80 and 140 degrees;
    wherein the first and the second stop (15) are separate from the panels (5);
    so that the bunch of keys hanging at the attachment point, in the retracted position of the arm and with the folder in the said upright situation and fully opened, occupies a position within the folder in which the bunch of keys is free from direct contact with the walls of the folder and freely hangs in the space enclosed by the opened folder, in a position determined solely by the direction of gravity (G);
    and so that, in the extended position of the arm and with the folder in said upright situation, the attachment point is positioned at a level at least 5 millimeters above the upper edge of the folder formed by the short edge (14) (see Fig. 6) + 7).
    [2]
    The binder according to claim 1, wherein the arm has a diameter between 0.5 and 3 millimeters and is made from a bundle of at least six steel wires that have been twisted into a wire rod, whereby the arm is suitably flexible to withstand a collision forces with a stop ( 15) sufficient to dampen.
    [3]
    3. Pouch as claimed in claim 1 or 2, wherein the pivoting means with which the proximal end of the arm is attached to the pouch are formed by a ball joint that allows the arm to rotate about its longitudinal axis and, when the arm is in its retracted position, can also be swiveled in the direction perpendicular to the hinge edge (11), from one panel to the other, over an angle of at least 20 degrees (see fig.
    11) ·
    [4]
    Folder according to one of claims 1-3, the arm pivoting is driven by gravity (G).
