Description:
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 storing keys or similar articles (hereafter commonly called "key") . A key means here a typically metal article, usually elongated, to be gripped manually and inserted in a key hole of the door of a house or car, for locking and unlocking the door by turning the inserted key clockwise or anti clockwise.

Prior art key wallets are e.g.: GB877325A, US1187852A, CH596796A5, DE3702505C1, EP1243198A1, US1494242A, US2849044, W093/22948, US2003/0226772 , US3677044, US2596716.

The words "elastic", "resilient", "yield", "flexible" are mainly used to explain that, elastically thus without permanent deformation, the relevant element, e.g. 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 of 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 of 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 of a rattling key bundle; allows storage of 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 the wallet by a simple movement of the user, e.g. his hand or wrist; allows safe storage of 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 millimetre; 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 met by providing that the attachment system is provided by or comprises an elongated, e.g. straight, element, also called "arm" which, at a first location along its length, e.g. its distal end or free tip, is, or can be, mounted to the key, and, at a second location along its length, e.g. 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, e.g. by virtue of gravity or movement of the wallet, between a retracted position, in which the associated keys, are e.g. stored within the wallet, and an extended position, e.g. 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% of 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 neatly stored in the wallet, remote from the opposite upright side edges 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 centred 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 millimetre and/or not more than 50 or 60 or 100 millimetre from the fixed end; and not more than 10 or 15 or 20 or 25 or 30 millimetre below the top edge of the wallet.

The arm preferably acts, preferably at least in the retracted position, as an outrigger, e.g. wall mounted, or like a cantilever or a cantilevered beam or a self-supporting arm or a boom, e.g. a lifting boom or a davit boom 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 (viz. 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 blade 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 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 millimetre and/or less than 50 or 60 or 100 millimetre; has a diameter of at least 0.5 millimetre and/or less than 3 or 4 or 5 millimetre; 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 elastomer 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 (e.g. within 3 or 5 or 10 millimetre) the pivot or spine of the wallet for opening the wallet and/or at or near (e.g. within 3 or 5 or 10 millimetre) 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 of at least 45 or 60 or 80 degrees; in the retracted position the arm extends substantially horizontal or parallel to the adjacent wallet edge, e.g. top edge, or obliquely, preferably downward, into the wallet e.g. 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, e.g. top edge, wherein "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 centre 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 angularly move 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 held 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 accordingly designed.

The wallet can be of a type having a rigid or stable shape, e.g. opposing panels have a mutual fixed position, or is always open, e.g. as shown in fig. 16, or of a type changing of shape, e.g. if opened or closed, e.g. as shown in fig. 6 or fig. 15. The wallet preferably can be opened and closed repeatedly.

The invention is preferably applied to a wallet type comprising two shell elements, e.g. halves (in here also called panels) which are associated by connection means such that they can move relative to one another such that a part of the one shell element, e.g. boundary edge, can move away from the corresponding part of the other shell element to open and close the wallet, e.g. to provide a V-shape if opened and a II-shape if closed. Preferably this is by pivoting or swivelling or rotating movement of one or both 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, comprise 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 (i.e. measured from the one to the opposite main wall) of the internal space (in unloaded, closed condition) at least 5 or 10 and/or not more than 20 or 25 or

30 millimetre (the keys, are housed in the internal space) ; elongated; length at least 50 or 80 or 90 millimetre and/ or maximum 110 or 120 millimetre, e.g. approximately 100 millimetre; width at least 30 or 40 millimetre and/or maximum 50 or 60 millimetre, e.g. approximately 45 millimetre; 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 wherein 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 of at least 2 or 3 or 4 or 5 millimetre, preferably one or two sides at the most provides such gap, preferably for substantially 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 of lock part; transmission means associated with operating button to actuate lock; button operated by pushing or turning action, e.g. of finger or thumb of 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 bias to 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 at 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 of internal type; in closed, unloaded condition an elongated, flat walled, sleeve like shape; the two panels are merely mutually connected at the spine; the two panels 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 faces are merely 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, wherein 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 strand or a wire.

The wire of the arm can be of steel material, possibly galvanised, 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 by, e.g., Carl Stahl Technocables GmbH (Germany) .

Preferred arm or wire rope diameters (in millimetre) : 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 strands 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 strand has at least 6 wires preferably around a core. Core can be a strand 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 millimetre and/or not more than 5 or 10 millimetre if loaded by 30 gram of keys (a metal house key typically weighs in the order of 15 gram) ; and/or at least 0.2 or 0.5 millimetre and/or not more than 1 or 2 millimetre 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, e.g 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 storing 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 permanent 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: comprising two shell elements, e.g. halves which are associated by connection means such that they can move relative to one another such that a part of the one shell element, e.g. boundary edge, can move away from the corresponding part of the other shell element to open and close the wallet; comprising 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 merely 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 millimeter, a width between 30 and 60 millimeter and a thickness between 5 and 30 millimeter, if unloaded and closed.

Meaning of the reference signs: wallet 1, key 2, aperture 3 in key grip, operating button 4 of lock, panel providing main face or side 5, key attachment system 6, arm (preferably a rod) 7, linking element 8, key retaining element 9 (e.g. loop type), pivot axis 11 of wallet, longitudinal edge 12 of 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 e.g. fig. 1, the free or distal longitudinal edges 12 (viz. e.g. fig. 11) of the superposed panels (i.e. the longitudinal edges distal from the pivot axis 11) are near each other while in the open wallet position, see e.g. 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, e.g. 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 is 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.

6 while retaining six metal keys of 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, wherein the arm 7 extends almost horizontal, if the pivot axis 11 extends vertical, such that the keys are located approximately centrally of 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 proper 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 centre position due to the action of gravity forces if the wallet is oriented such that the pivot axis 11 is vertical and the arm

7 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, wherein the arm 7 is in its retracted position. The arm 7 can pivot from the one panel 5 to the opposite panel 5, thus 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 storing 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 bulge 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 an permanent 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. Of the wallet merely the pivot 11 and the top edge 14 of 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 of 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 of different wire rope designs. Fig. 20 a strand of 7 wires of 0,09-0, 75 mm; Fig. 21 a strand of 19 wires of 0,15-5,00 mm; Fig. 22 and 23 six strands, each of seven wires of 1,50-5,00 mm respectively 0, 12-6, 00 mm, around a fibre core respectively a wire strand core; Fig. 24 and 25 six strands, each of 19 wires of 3,00-8,00 mm respectively 0,45-8,00 mm, around a fibre core respectively a wire strand core.

Many wallet embodiments disclosed in here operate as follows: In the closed position, the wallet is held in a single hand and the operating button is operated by a finger of said hand to release the lock. Then the wallet is moved to its open position (viz. e.g. fig. 6) . Subsequently, by an adequate wrist movement of said single hand, the arm (7) is pivoted from the retracted to the extended position such that the keys are brought outside the wallet (viz. 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 of said single hand. After again opening of the wallet, the arm can be moved back to its retracted position (viz. 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 comprise magnetic means. Also further alternatives are possible.

The drawing, the specification and claims contain many features in combination. The skilled person will consider these also individually and combine them to further embodiments. Also different embodiments belong to the invention. Features of different in here disclosed embodiments can in different manners be combined and different aspects of some features are regarded mutually exchangeable. All described or in the drawing disclosed features provide as such or 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. e.g. fig. 12) to temporarily support the slack chain in the retracted position, following an L shape.
