The bulb and the connection circuit (16) are fitted on a lens (14) inserted in a circular accommodation (62) at the rear of the housing (11) and rotatable between a first rest position allowing access to the first compartment (30) for removal or insertion of the batteries and a second, in-use, position for supplying the bulb with voltage and blocking access to the compartment.

Description

L'invention est relative à une lampe d'éclairage électrique à boítier renfermant:

  • une source de courant continu comprenant une pluralité de piles logées dans un premier compartiment du boítier,
  • un circuit de raccordement électrique de l'ampoule, comprenant des contacts d'alimentation connectés électriquement avec la source de courant au moyen d'un interrupteur,
  • et un capot de visualisation comprenant un réflecteur associé à un écran transparent pour l'émission d'un faisceau lumineux issu de l'ampoule lors de la phase d'excitation.
The invention relates to an electric lighting lamp with a housing containing:
  • a direct current source comprising a plurality of batteries housed in a first compartment of the case,
  • a circuit for the electrical connection of the bulb, comprising power contacts electrically connected with the current source by means of a switch,
  • and a display cover comprising a reflector associated with a transparent screen for the emission of a light beam coming from the bulb during the excitation phase.

Les lampes d'éclairage en forme de torches comportent généralement des enveloppes tubulaires en matériau isolant ou métallique, ayant au niveau du fond, un orifice obturable par un embout de fermeture. La mise en service d'une telle lampe nécessite l'enlèvement de l'embout terminal, suivi de l'insertion des piles par le fond de l'enveloppe. L'allumage et l'extinction de l'ampoule s'effectuent ensuite au moyen d'un interrupteur intégré, lequel est actionné par la rotation de la bague lorsque cette dernière arrive dans une position de fin de course. L'interrupteur est constitué soit par un contact semi-fixe coopérant directement avec l'une des bornes de l'ampoule, soit par une pièce de support déplaçable en translation limitée à l'intérieur de l'enveloppe. Le contact semi-fixe du premier dispositif peut être soumis à des problèmes d'oxydation susceptibles d'occasionner des mauvais contacts et des pannes d'allumage. Le deuxième dispositif connu est compliqué, et est généralement utilisé pour des lampes torches à enveloppes métalliques. Torch-shaped lighting lamps generally have tubular envelopes of insulating or metallic material, having at the level of bottom, an orifice closable by a closing end piece. Commissioning of such a lamp requires the removal of the end fitting, followed by inserting the batteries through the bottom of the envelope. Switching on and off the bulb is then carried out by means of an integrated switch, which is actuated by the rotation of the ring when the latter arrives in a end position. The switch consists either of a semi-fixed contact cooperating directly with one of the terminals of the bulb, either by a support part displaceable in limited translation inside the envelope. The semi-fixed contact of the first device may be subject to problems oxidation likely to cause bad contacts and breakdowns ignition. The second known device is complicated, and is generally used for torches with metal envelopes.

Sur les figures 1 à 10, une lampe 10 d'éclairage électrique comporte un boítier 11 allongé en matériau isolant pour le logement des piles 12A, 12B; 12C, 12D, un barillet 14 équipé d'un circuit de raccordement 16 électrique de l'ampoule 18, et un capot de visualisation 20 comprenant un réflecteur 22 et un écran 24 transparent pour la transmission du faisceau lumineux émis par l'ampoule 18 lors de son excitation.In FIGS. 1 to 10, an electric lighting lamp 10 includes a case 11 elongated in insulating material for housing batteries 12A, 12B; 12C, 12D, a barrel 14 equipped with an electrical connection circuit 16 of the bulb 18, and a display cover 20 comprising a reflector 22 and a transparent screen 24 for the transmission of the light beam emitted by the bulb 18 during its excitation.

Le barillet 14 est formé par un corps 26 cylindrique en matériau isolant moulé, comprenant une paroi de séparation 28 ajourée, destinée à subdiviser l'intérieur du boítier 11 en un premier compartiment 30 renfermant les piles 12A, 12B, 12C, 12D et le dispositif de raccordement 16, et un deuxième compartiment 32 de logement de l'ampoule 18, et du réflecteur 22.The barrel 14 is formed by a cylindrical body 26 of molded insulating material, comprising a perforated partition wall 28, intended to subdivide the interior of the housing 11 in a first compartment 30 containing the batteries 12A, 12B, 12C, 12D and the connection device 16, and a second compartment 32 for housing the bulb 18 and the reflector 22.

En référence aux figures 4 à 6, le culot de l'ampoule 18 est vissé dans une douille 34 tubulaire isolante solidarisée à l'une des faces 36 de la paroi 28. L'autre face 38 opposée de la paroi 28 porte le circuit de raccordement 16, comportant un premier contact 40 d'alimentation en liaison électrique permanente avec le culot métallique de l'ampoule 18, et un deuxième contact 42 d'alimentation en liaison électrique permanente avec la borne 44 isolée de l'ampoule 18.With reference to FIGS. 4 to 6, the base of the bulb 18 is screwed into a insulating tubular sleeve 34 secured to one of the faces 36 of the wall 28. The other face 38 opposite the wall 28 carries the connection circuit 16, comprising a first electrical connection supply contact 40 permanent with the metal base of the bulb 18, and a second contact 42 supply in permanent electrical connection with terminal 44 isolated from bulb 18.

Sur les figures 6 et 8, le premier contact 40 et formé par une lame de cuivre de faible épaisseur s'étendant radialement le long de la face 38 de la paroi 28, en traversant la surface latérale de la douille 34 de manière à venir en engagement avec le culot de l'ampoule 18. Le matériau de la lame métallique peut être en cuivre, en laiton, en bronze, ou en acier. Le premier contact 40 comporte dans la zone médiane une protubérance 46 destinée à venir en contact avec la borne positive 48 d'une première série de deux piles 12A, 12B cylindriques empilées axialement sur une même colonne dans le compartiment 30.In FIGS. 6 and 8, the first contact 40 and formed by a copper strip of small thickness extending radially along the face 38 of the wall 28, by crossing the lateral surface of the sleeve 34 so as to come into engagement with the base of the bulb 18. The material of the metal blade can be copper, brass, bronze, or steel. The first contact 40 comprises in the middle zone a protuberance 46 intended to come into contact with the positive terminal 48 of a first series of two batteries 12A, 12B cylindrical stacked axially on the same column in the compartment 30.

Le deuxième contact 42 s'étend également selon une direction radiale le long de la face 38 en étant décalé du premier contact fixe 40 par une angle prédéterminé d'environ 90°. Le deuxième contact 42 est plus large que le premier, et comporte un orifice 50 dans lequel est agencé un poussoir de commande 52 monté à pivotement sur la paroi 28 du corps 26. Le deuxième contact 42 est doté d'un bossage 54 destiné à venir en engagement avec la borne négative 56 d'une deuxième série de deux piles 12C, 12D cylindriques s'étendant parallèlement avec la première série de piles 12A, 12B dans le compartiment 30 (figures 7 et 9).The second contact 42 also extends in a radial direction along of the face 38 while being offset from the first fixed contact 40 by an angle predetermined about 90 °. The second contact 42 is wider than the first, and has an orifice 50 in which is arranged a pusher control 52 pivotally mounted on the wall 28 of the body 26. The second contact 42 has a boss 54 intended to come into engagement with the negative terminal 56 of a second series of two cylindrical 12C, 12D batteries extending in parallel with the first series of batteries 12A, 12B in the compartment 30 (Figures 7 and 9).

Le fond 57 fermé du boítier 11 renferme deux ressorts de compression 58, 60 reliés électriquement entre eux, et sur lesquels reposent les deux piles inférieures 12B et 12D des deux colonnes. Les deux ressorts 58, 60 sont réalisée au moyen d'un fil conducteur permettant la mise en série des quatre piles 12A, 12B, 12C, 12D. A l'opposé du fond 57, le boítier 11 comprend un logement 62 circulaire dans lequel est introduit le barillet 14, ledit logement étant délimité par un embout 64 à filetage externe sur lequel est vissée la bague 66 rotative du capot de visualisation 20 (figure 1).The closed bottom 57 of the housing 11 contains two compression springs 58, 60 electrically interconnected, and on which the two batteries rest lower 12B and 12D of the two columns. The two springs 58, 60 are produced by means of a conductive wire allowing the series of the four 12A, 12B, 12C, 12D batteries. Opposite the bottom 57, the housing 11 includes a circular housing 62 into which the barrel 14 is introduced, said housing being delimited by an end piece 64 with external thread on which is screwed the rotating ring 66 of the display cover 20 (Figure 1).

A l'intérieur du logement 62, le barillet 14 est monté à rotation limitée, et est susceptible d'occuper une première position de repos autorisant la mise en place ou le retrait des piles 12A, 12B, 12C, 12D, et une deuxième position de travail pour la commande d'éclairage de la lampe 10. L'ampoule 18 s'étend dans l'alignement axial du barillet 14.Inside the housing 62, the barrel 14 is mounted with limited rotation, and is likely to occupy a first rest position authorizing the setting place or remove batteries 12A, 12B, 12C, 12D, and a second position of work for the lighting control of the lamp 10. The bulb 18 extends in the axial alignment of the barrel 14.

La première position de repos est représentée sur la figure 2, dans laquelle l'ouverture 68 de la paroi 28 ajourée permet l'accès au compartiment 30 pour l'introduction ou l'enlèvement des piles. Le passage de la première position de repos vers la deuxième position de travail s'opère par un mouvement de rotation d'un demi-tour du barillet 14 exercé manuellement dans le sens des aiguilles d'une montre (figure 3). Ce mouvement de rotation du barillet 14 est facilité grâce à la présence d'une rampe 70 oblique (figures 5 et 6) sur la face 38 de la paroi de séparation 28. La réaction de la rampe 70 sur les piles 12A, 12C provoque un mouvement de compression des ressorts 58, 60 pour assurer la pression de contact lorsque la protubérance 46 du premier contact 40, et le bossage 54 du deuxième contact 42 arrivent respectivement en appui sur la borne positive 48, et la borne négative 56 des piles 12A, 12C. Le mouvement de rotation du barillet 14 vers la deuxième position permet un nettoyage automatique par frottement des contacts 40 et 42 sur les piles 12A et 12C.The first rest position is shown in Figure 2, in which the aperture 68 of the perforated wall 28 allows access to the compartment 30 for inserting or removing batteries. Going from the first position rest to the second working position is effected by a movement of rotation of a half-turn of the barrel 14 exerted manually in the direction of clockwise (Figure 3). This rotational movement of the barrel 14 is facilitated by the presence of an oblique ramp 70 (Figures 5 and 6) on the face 38 of the partition wall 28. The reaction of the ramp 70 on the batteries 12A, 12C causes a compression movement of the springs 58, 60 to ensure the contact pressure when the projection 46 of the first contact 40, and the boss 54 of the second contact 42 respectively come into contact on the positive terminal 48, and the negative terminal 56 of the batteries 12A, 12C. The rotational movement of the barrel 14 towards the second position allows a automatic cleaning by friction of contacts 40 and 42 on 12A batteries and 12C.

Le poussoir de commande 52 est formé par un levier élastique susceptible de se trouver dans une position inactive ou dans une position active en fonction de la course en translation du réflecteur 22 lors de la rotation de la bague 66.The control button 52 is formed by an elastic lever capable of be in an inactive position or in an active position depending of the translational travel of the reflector 22 during the rotation of the ring 66.

Dans la position inactive (figure 7), le poussoir 52 ne traverse pas l'orifice 50 du deuxième contact 42, et le circuit électrique d'alimentation de l'ampoule 18 est fermé pour assurer l'éclairage. La rotation de la bague 66 permet un réglage du foyer pour ajuster le champ du faisceau lumineux émis à travers l'écran 24 translucide. Un tel réglage du faisceau lumineux est décrit en détail dans le document FR-A- 2 513 740. In the inactive position (Figure 7), the pusher 52 does not pass through the orifice 50 of the second contact 42, and the electric circuit supplying the bulb 18 is closed for lighting. The rotation of the ring 66 allows a focus adjustment to adjust the field of light beam emitted through the translucent screen 24. Such adjustment of the light beam is described in detail in document FR-A- 2,513,740.

La position active du poussoir 52 est obtenue en fin de course de vissage de la bague 66 rotative lorsqu' une butée du réflecteur 22 déplace le poussoir 52 à travers l'orifice 50 du deuxième contact 42 (figure 10). L'extrémité du poussoir 52 provoque un léger mouvement de recul selon la direction axiale des piles 12C, 12D en comprimant le ressort 60. Il en résulte une interruption du courant dans le circuit électrique d'alimentation de l'ampoule 18, suite à la séparation de la borne négative 56 de la pile 12C avec le deuxième contact 42 du barillet 14.The active position of the pusher 52 is obtained at the end of the screwing stroke of the ring 66 rotates when a stop of the reflector 22 moves the pusher 52 through the orifice 50 of the second contact 42 (Figure 10). The end of the pusher 52 causes a slight backward movement in the axial direction batteries 12C, 12D by compressing the spring 60. This results in an interruption of current in the electric circuit supplying the bulb 18, following the separation of the negative terminal 56 of the battery 12C with the second contact 42 of barrel 14.

Les deux contacts 40, 42 restent fixes et en liaison électrique permanente avec le culot métallique et la borne isolée 44 de l'ampoule 18 lorsque le poussoir 52 est déplacé vers la position active. La fonction interrupteur est ainsi reportée vers une zone décalée dans le compartiment 30, suite à la séparation de la pile 12C et du bossage 54 du deuxième contact 42.The two contacts 40, 42 remain fixed and in permanent electrical connection with the metal base and the insulated terminal 44 of the bulb 18 when the pusher 52 is moved to the active position. The switch function is thus transferred to an offset zone in compartment 30, following the separation of the battery 12C and the boss 54 of the second contact 42.

La mise en service et le fonctionnement de la lampe d'éclairage 10 selon l'invention sont les suivants:The commissioning and operation of the lighting lamp 10 according to the invention are as follows:

La lampe 10 est montée en usine avec le barillet 14 inséré dans le logement 62 prévu à la partie supérieure du boítier 11 isolant. L'ampoule 18 est vissée dans la douille 34 isolante de la paroi 28, et se trouve en liaison électrique avec les deux contacts 40, 42 fixes du circuit de raccordement 16 solidaire du barillet 14. Le capot de visualisation 20 est vissé partiellement sur l'embout 64 du boítier 11.The lamp 10 is factory fitted with the barrel 14 inserted in the housing 62 provided at the upper part of the insulating housing 11. The bulb 18 is screwed in the insulating sleeve 34 of the wall 28, and is in electrical connection with the two fixed contacts 40, 42 of the connection circuit 16 secured to the barrel 14. The display cover 20 is partially screwed onto the end piece 64 of the housing 11.

Pour la mise en service de la lampe 10 ou le remplacement des piles usagées, l'utilisateur dévisse préalablement le capot 20, et actionne le barillet 14 rotatif vers la position de repos permettant l'accès au compartiment 30 du boítier 11 à travers l'ouverture 68 de la paroi de séparation 28. ll suffit ensuite d'insérer les piles 12A, 12B, 12C, 12D (figure 2) par l'ouverture 68, en respectant les polarités et la mise en série électrique des piles 12A, 12B, 12C, 12D. On remarque que l'introduction des piles s'effectue par la face avant du boítier 11, le fond 57 étant complètement fermé et dépourvu d'orifice obturable.For putting the lamp into operation 10 or replacing the batteries used, the user unscrews the cover 20 beforehand, and actuates the barrel 14 rotatable to the rest position allowing access to compartment 30 of the housing 11 through the opening 68 of the partition wall 28. Then it suffices insert the batteries 12A, 12B, 12C, 12D (figure 2) through the opening 68, respecting the polarities and the electrical series connection of the batteries 12A, 12B, 12C, 12D. Note that the batteries are inserted via the front of the housing 11, the bottom 57 being completely closed and devoid of orifice closable.

Dans la première position de repos du barillet 14, les deux contacts 40, 42 du circuit de raccordement 16 ne sont pas en engagement avec les bornes respectives des piles 12A, 12C, et l'ampoule 18 est éteinte en permanence indépendamment de la position du réflecteur 22, et de l'état ouvert ou fermé de l'interrupteur.In the first rest position of the barrel 14, the two contacts 40, 42 of the connection circuit 16 are not in engagement with the terminals respective batteries 12A, 12C, and the bulb 18 is permanently off independently of the position of the reflector 22, and of the open or closed state of the switch.

L'allumage de l'ampoule 18 n'est possible qu'après déplacement du barillet 14 vers la deuxième position de travail (figure 3). Les deux contacts 40, 42 viennent en appui sur les bornes des piles supérieures 12A, 12C, ce qui provoque le nettoyage des contacts, et la mise sous tension de l'ampoule 18. L'accès au compartiment 30 du boítier 11 est alors interdit, étant donné que l'ouverture 68 de la paroi 28 est obturée par une protubérance 72 interne du boítier 11. Le poussoir 52 de commande de l'interrupteur est en permanence dans la position inactive lorsque la bague 66 de capot 20 n'est pas accouplée à l'embout 64 du boítier 11.The lighting of the bulb 18 is only possible after displacement of the barrel 14 to the second working position (Figure 3). The two contacts 40, 42 come to bear on the terminals of the upper batteries 12A, 12C, which causes the contacts to be cleaned and the bulb 18 to be energized. Access to compartment 30 of the housing 11 is then prohibited, given that the opening 68 of the wall 28 is closed by an internal protuberance 72 of the case 11. The push button 52 for controlling the switch is permanently in the inactive position when the cover ring 66 is not coupled at the tip 64 of the housing 11.

La mise en place du capot 20 s'effectue par vissage de la bague 66 sur l'embout 64, et le déplacement en translation du réflecteur 22 dans une position intermédiaire prédéterminée permet de focaliser le champ du faisceau lumineux. La butée du réflecteur 22 n'entre pas en engagement avec le poussoir 52, et l'interrupteur reste fermé grâce au maintien de la pile 12C sollicitée contre le deuxième contact 42 par l'action de rappel du ressort 60 (figure 7).The cover 20 is put in place by screwing the ring 66 onto the end piece 64, and the translational movement of the reflector 22 in a predetermined intermediate position allows to focus the field of light bleam. The stopper of the reflector 22 does not engage with the pusher 52, and the switch remains closed by maintaining the battery 12C biased against the second contact 42 by the spring return action 60 (figure 7).

LA figure 8 montre une vue identique à celle de la figure 7, mais avec une coupe le long du premier contact 40, lequel reste en permanence en engagement avec la pile 12A.FIG. 8 shows a view identical to that of FIG. 7, but with a cuts along the first contact 40, which remains permanently in engagement with 12A battery.

La figure 9 est une vue de la lampe 10 avec une coupe axiale à travers toutes les piles 12A, 12B, 12C, 12D des deux colonnes. L'interrupteur se trouve dans l'état fermé, et les deux contacts 40, 42 se trouvent en appui sur les deux piles 12A, 12C supérieures.Figure 9 is a view of the lamp 10 with an axial section through all the batteries 12A, 12B, 12C, 12D of the two columns. The switch is located in the closed state, and the two contacts 40, 42 are supported on the two 12A, 12C upper batteries.

En référence à la figure 10, l'interrupteur est commuté vers l'état ouvert en fin de course de vissage de la bague 66. La butée du réflecteur 22 pousse le poussoir 52 à travers l'orifice 50 du deuxième contact 42, et déplace les piles 12C, 12D vers le bas à l'encontre de la force de rappel du ressort 60. Il en résulte un intervalle d'isolement entre le deuxième contact 42, et la borne négative de la pile 12C, avec l'interruption du circuit d'alimentation de l'ampoule 18. Dans cette position de fin de course, l'ampoule est éteinte.Referring to Figure 10, the switch is switched to the open state at the end of the screwing race of the ring 66. The stop of the reflector 22 pushes the pusher 52 through the orifice 50 of the second contact 42, and moves the batteries 12C, 12D downwards against the restoring force of the spring 60. It an insulation gap results between the second contact 42, and the terminal 12C battery negative, with interruption of the power supply circuit the bulb 18. In this end of travel position, the bulb is off.

L'ouverture de l'interrupteur par l'actionnement du poussoir 52 s'exerce sensiblement dans l'axe de la pile 12C grâce au passage du poussoir 52 à travers l'orifice 50 du deuxième contact 42.The opening of the switch by actuation of the pusher 52 is exercised substantially in the axis of the stack 12C thanks to the passage of the pusher 52 to through the orifice 50 of the second contact 42.

Le boítier 11 pourrait bien entendu être réalisé en un matériau métallique, notamment à base d'aluminium. La polarité des piles 12A et 12C au niveau des contacts 40, 42 peut bien entendu être inversée, à condition de conserver la mise en série électrique de toutes les piles.The housing 11 could of course be made of a metallic material, especially based on aluminum. The polarity of the 12A and 12C batteries at the level contacts 40, 42 can of course be reversed, provided that the electrical serialization of all the batteries.

Sur les figures 11 à 14 ,la surface inférieure 127 du boítier 11 est doté d'un orifice 130 borgne délimité par une protubérance 132 interne venant de moulage avec le boítier 11. L'orifice 130 renferme avantageusement une ampoule de réserve 134, et des moyens de verrouillage 136 permettant le montage de la lampe sur une platine de fixation 138.In Figures 11 to 14, the lower surface 127 of the housing 11 is with a blind orifice 130 delimited by a protuberance 132 internal from molding with the housing 11. The orifice 130 advantageously contains a reserve bulb 134, and locking means 136 for mounting the lamp on a fixing plate 138.

Les moyens de verrouillage 136 comportent deux boutons 140,142 de maintien agencés sur les deux côtés opposés de l'orifice 130, et coopérant à l'intérieur de l'orifice 130 avec une épingle 144 métallique en forme de U.The locking means 136 comprise two buttons 140,142 holding arranged on the two opposite sides of the orifice 130, and cooperating inside the orifice 130 with a pin 144 metallic U-shaped.

La platine 138 de fixation comprend une plaque en matériau isolant moulé, équipée d'une patte de positionnement 146, et d'une paire d'ergots 148,150 d'accrochage permettant le clipsage de la lampe 10 sur les boutons de maintien 140,142 de la platine 138.The fixing plate 138 comprises a plate of insulating material molded, equipped with a positioning tab 146, and a pair 148.150 lugs for hanging the lamp 10 on the holding buttons 140, 142 of the plate 138.

Dans la position accrochée (figure 13) de la platine 138, les deux ergots 148,150 se trouvent prisonniers des boutons de maintien 140,142, lesquels sont sollicités vers une position active par l'action élastique de rappel de l'épingle 144. Il en résulte un verrouillage positif de la lampe 10 sur la platine 138.In the hooked position (FIG. 13) of the plate 138, the two pins 148,150 are trapped in the holding buttons 140,142, which are biased towards an active position by the elastic return action of the pin 144. This results in a positive locking of lamp 10 on plate 138.

La platine 138 comprend sur les côtés latéraux deux saignées 154,156 destinées à recevoir une sangle si l'utilisateur souhaite un usage en lampe frontale. La sangle est fixée dans ce cas autour de la tête de l'utilisateur , et la lampe se trouve légèrement en saillie dans la zone médiane au-dessus de la tête.Plate 138 includes two grooves on the lateral sides 154,156 intended to receive a strap if the user wishes a use as a headlamp. The strap is fixed in this case around the head of the user, and the lamp is slightly protruding in the middle area above the head.

Il est également possible d'adapter la platine directement sur un casque, ou tout autre élément mobile, par exemple une bicyclette.It is also possible to adapt the plate directly on a helmet, or any other mobile element, for example a bicycle.

Pour désaccoupler la lampe 10 de sa platine de fixation 138 (figure 12), il est nécessaire de pousser depuis l'extérieur les boutons 140,142 l'un vers l'autre pour obtenir le déverrouillage des ergots 148,150 dans la position inactive. La commande manuelle de déverrouillage s'effectue à l'encontre de la force de rappel de l'épingle 144 élastique, et nécessite une poussée simultanée sur les deux boutons 140,142.To disconnect the lamp 10 from its mounting plate 138 (figure 12), it is necessary to push the buttons from outside 140,142 towards each other to obtain the unlocking of the pins 148,150 in the inactive position. The manual control of unlocking is carried out against the restoring force of the elastic pin 144, and requires a simultaneous push on the two buttons 140,142.

Il est ainsi possible de transformer rapidement une lampe frontale en lampe torche après le déverrouillage de la platine de fixation 138.It is thus possible to quickly transform a headlamp as a flashlight after unlocking the mounting plate 138.

Le fond du boítier 11 est pourvu d'autre part d'un anneau 158 fermé pour le passage d'une sangle. Sur la figure 15, la sangle 160 attachée à la platine 138, traverse avantageusement l'anneau 158 pour constituer une dragonne .The bottom of the housing 11 is provided on the other hand with a closed ring 158 for the passage of a strap. In Figure 15, the strap 160 attached to the plate 138, advantageously crosses the ring 158 to make a wrist strap.
