  "Structure de montage   liberté     auto-ajustable",-   

 <Desc/Clms Page number 2> 

 
La présente invention est relative au montage des appareils à rebord périphérique, tels que les éviers, les unités de rangement et analogues, dans des dessus de comptoirs, des cloisons ou des armoires et/ou au montage de   panneau:ou   sections amovibles d'appareils, de parois ou d'armoires. 



   Plus   particulièrement,   elle concerne une structure ou un dispositif de montage à auto-réglage et auto-verrouillage. pour la fixation serrée de l'appareil ou du panneau dans sa position fixée. dispositif est rapidement libérable pour le retrait de l'unité quand cela est nécessaire, sans l'aide de tournevis ou des autres outils   habituellement   requis pour les installations de ce type. 



   Les constructeurs d'appareils tels que .les éviers et les unités de rangement, et ceux qui installent ces unités, ont depuis longtemps ressenti le besoin d'un dispositif simple réduisant le temps nécessaire pour l'installation et éliminant les assemblages longs à réaliser du type à vis. Les dispositifs de serrage du type à vis exigent généralement le retrait du dessus de comptoir, de l'armoire ou de l'installation fixé de façon presque définitive dans les armoires pour la mise en place de l'appareil, ou bien le travail de l'installateur dans des conditions considérables d'inconfort à l'intérieur de l'armoire. 



   Même dans ce dernier cas, l'appareil n'est pas cor- rectement posé en raison de la difficulté de placer et de serrer; de façon appropriée de tels dispositifs vissés quand   l'instal-   lateur est dans une telle position.      

 <Desc/Clms Page number 3> 

 



   Les buts dé l'invention sont en conséquence les sui- vanta: fournir une structure de montage appliquant de   fa- !        çon appropriée le bord de l'appareil contre la surface de montage de façon' à former un joint serré ;   fournir   un dispositif d'assemblage diminuant le temps et le travail nécessaires' pour l'installation d'un appareil; -fournir un dispositif pouvant être placé en position fixée en usine ou dans un lieu éloigné de l'orifice de réception de l'appareil et qui demeure à l'emplacement approprié sur l'unité à la Suite d'assemblages et/ou de retraits répétés de   l'unité ;    - fournir une structure que l'on peut installer dans un comptoir ou une base d'appareil sans qu'il soit besoin d'accé- der à des espacée mal commodes sous les comptoirs ou derrière des orifices ;

   - fournir une structure de montage permettant une li- bération rapide de l'effort de pincement pour le retrait de l'ap- pareil quand cela est nécessaire ; .fournir une structure éliminant les régi âges   néces-   saires avec les ensembles vissés, et réduisant ainsi les ris- ques d'endommagement des vernis;ou de déformation des reborda, etc., souvent provoqués par des réglages maladroits des vis des autres dispositifs de montage ; - Un moyen pour replacer de façon rapide et précise le dispositif de pincement   après   retrait de l'appareil, ce qui 
 EMI3.1 
 permet sa réinstallation rapide ;

   - -fournir une structure suffisamment souple pour s'a- juster automatiquement aux variations normales des tolérances di- mentionnelles des orifices des appareils tout en conservant l'ac- 

 <Desc/Clms Page number 4> 

 tion de pincement et le joint serré de la structure ; - fournir une structure de montage   satisfai-   sant tous les besoins d'un temps d'installation   minimum,   d'une action de joint serré, d'une souplesse suffisante pour s'ajuster automatiquement à la dimension de l'orifice, qui   élimine'   lesrégalages des systèmes vissés, qui est facilement libérable pour le retrait de l'appareil, qui demeure à l'em0pla- cernent correct après libération et retrait de l'appareil,

   et que l'on peut facilement et rapidement   replacer   en vue du ré- assemblage dans l'orifice prévu pour   l'appareil.

La   figure   15 est une coupe partielle d'un autre mode de réalisation pour les fours montés dans des cloisons et ana- logues. 



   En se référant plus en détail la figure 1, on y a représenté une paillasse de type classique 10 dans laquelle un orifice est destiné à recevoir un évier classique 12. Le bord externe du rebord de l'évier est plus large que l'orifice de la paillasse et rencontre le dessus de la surface de la paillasse. 



  Un certain nombre de pinces 14 représentées en pointillés sont réparties le long du rebord de l'appareil. 



   La figure 2 montre un élément de retenue de ressort en forme de canal 16 fixé au rebord 18 de l'évier. Le bord exter- ne 20 du rebord 18 de l'évier prend appui contre la surface      22 de la paillasse 24. Une bande de   douane   26 est   représen-   tée contre le bord interne 30 de l'orifice de la apillasse 24. 



  Il est possible d'éviter cette bande dans certains typus   d'ins-   tallations. D'autres modèles dans lesquels cette bande ne fi- 

 <Desc/Clms Page number 6> 

 gure pas sont représentés aux figures 7,10 et 13. La fonction est principale de la bande de clouage représentée ici/de per- mettre de plus grandes variations de la dimension de l'orifce en assurant une distance uniforme de la face supérieure 22 de la paillasse   24   à la zone de pincement sous-pression 34 du ressort   32.   



   Le ressort 32 est représenté à la figure 2 en posi- tion verrouillée. Dans cette position, la portion 34   du ressorte   
32 est   coincée   contre la semelle 28 de la bande de clouage 26. 



   La portion intermédiaire 36 du ressort 32 est logée dans une rainure   38   formée dans l'élément de retenue de ressort 16. 



   Les deux extrémités en vochets 40 du ressort 32 sont insérées dans des fentes ou rainures 42 de l'élément 16. Dans cette po- sition les extrémités en crochets sont verrouillées dans l'élé- sent de retenue, en maintenant le ressort fermement en   position.   



   La figure 3 est une vue montrant le même ensemble que la figuré 2, mais avec le ressort en position libérée. Dans ce cas, les deux bras 44 du ressort ont été légèrement repoussés . ensemble ce qui libère les extrêmités en crochets   40.   Il est bien entendu qu'à ce moment la force de pincement de la portion 
34 du ressort, coincée contre la bande 26, provoque le pivote- ment du ressort sur sa portion intermédiaire 36 et le glisse- ment vers le haut des bras 44 dans l'encoche 42 de l'élément de retenue   16.     Quand/Le   ressort pivote de cette manière, la portion 34 du ressort est écartée du bord 26 de la bande 26, ce qui libère l'action de pincement et permet le retrait de l'appareil sans difficulté.

   Des   camhures   46 sont prévues dans les bras du   ressort;   pour que ce dernier demeure en position re- lâchée pendant le retrait de l'appareil. 



     On   notera que la libération du pincement du ressort résulte rapidement d'une pression des bras 44 entre le pouce 

 <Desc/Clms Page number 7> 

 et l'index et qu'aucun tournevis ou autre instrument n'est nécessaire pour libérer ou ajuster la pression du dispositif. 



   La figure 4 montre Clairement l'encoche 42 vue du dessous de l'élément de retenue 16 et comment les extrémités cro- chues des bras 44 du ressort 32,sont en prise avec l'encoche 42. 



  Il est bien entendu que l'élément de retenue en forme de canal 16 peut être réalisé sous forme d'un long canal coopérant avec plusieurs ressorts sur toute sa longueur ou bien qu'il peut .être désirable dans certains cas de disposer d'un élément de retenue séparé pour chaque ressort. 



   La figure 5 montre le ressort séparé, ce qui permet de voir clairement la portion intermédiaire 36 qui   glisse   et pi- vote dans la rainure 38 de l'élément de retenue 16. 
 EMI7.1 
 



  La figure 16,.,illustre l'action du ressort quancl'ap- pareil est introduit à force dans   l'orifice.   Le bord 20 du   re-   bord 18 de l'appareil ne touche pas encore le dessus 22 de la paillasse 24, Quand la bosse 48 du ressort passe sur le bord 28 de la bande 26, la portion intermédiaire 36 du ressort est repoussée dans la rainure 38 de l'élément de retenue 16. Quand la bosse 48 a dépassé le bord 28, la tension du ressort repousse la portion inclinée 34 de la pince 32 vers l'extérieur en la coinçant étroitement contre le bord de la bande de clouage 28 comme il est représenté sur la figure 2. Son action assure donc l'ajustement automatique aux tolérances dimensionnelles   norma-   les avec beaucoup de souplesse et une pression de pincement maximum. 



   La figure 7 illustre une variante du même   principe   général. Un élément de retenue de ressort 52 est fixé à un pan- neau 50 et maintenu étroitement eontre un élément de cornière 56 d'un appareil au moyen d'un ressort 58. Ici encore, la por- 

 <Desc/Clms Page number 8> 

 tion   64   du ressort se place dans une rainure 54 de l'élément 52. 



  Les extrémités crochues 62 des bras 66 du ressort 58 sont an- crées dans des fentes de portions 68 de l'élément 52. 



   La figure 8 illustre les extrémités crochues 62 à l'état libéré, le ressort 58, ayant pivoté autour de sa portion intermédiaire 64, ayant libéré la pression de pincement de la zone 60 sur le bord 70 de la cornière 56. Le panneau est prêt à être retiré. 



   Les figures 9, 10 et 11 sont des vues d'une variante de la pince réalisée en matière élastique plate au lieu de fil métallique. L'élément de retenue monté sous le rebord 18 est également différent. La pince et l'élément de retenue modifiés sont désignés respectivement par 74 et 76. Pour plus de clarté, , la pince 74 est représentée séparément sur la figure 12 et   lfi-   gure 14 montre l'élément de retenue modifié 76 vue depuis   14-14 :   de la figure 13 . ' 
Dans la pince   74   une encoche 78   esprévue   pour as- surer la flexion désirée de la pince dans cette zone coudée. La pince présente une surface 84 à l'angle désiré pour guider de fa- çon appropriée l'appareil dans l'orifice. 



   La figure 12 montre la pince 74 qui possède un bras extérieur 89 entaillé suivant 88 et un bras 90 avec une fente 86. 



   Il est bien entendu qui les bords 98 de l'orifice 102 de l'élé- ment de retenue 76 (voir figure 14) sont tels qu'ils glissent dans les encoches 88 de la pince 74. La saillie 100 dans l'ori- fice 102 de l'élément 76 s'insère dans la fente 86 du bras in- térieur 90 de la pince 74 au cours de la mise en place e t quand la pince 74 est dans la position normalement verrouillée des fi'- ?;ures 9 et 10. 



   En se référant aux figures 9, 10 et 11, on   vo.'c.   que la paillasse modifiée   24A     comporte/un   bourrelet 80. La surface 

 <Desc/Clms Page number 9> 

 inclinée 72 de la pince 74 assure un coincement contre le bord interne du bourrelet 80, Le bourrelet   80  donc le   même   but que la bande de clouage   26   des figures 2,3 et 6, et il permet des variations notables de la dimension de l'orifice de récep- !   ?;Ion   de l'appareil en assurant un espacement uniforme entre la surface supérieure 22 et le bord interne du bourrelet 80 contre lequel vient se coincer l'angle 72 du ressort 74 à la   manière   d'un coin. 



   IL est bien entendu que dans cette variante, quand la bras intérieur 90 du ressort 74 est légèrement repoussé vers le bras extérieur 89, la fente 86 de la pince 74 est libérée de sa position normalement verr-ouillée sur la portion 100 de l'encoche 102 de l'élément de retenue 76. Quand le bras intérieur est ain- si libéré, la force de pincement de la pente 72 de la pince 74 contre- le bord intérieur de l'orifice provoque le déplacement du bras intérieur 90 vers la position déverrouillée représentée à la figure 11. L'encoche 82 de la pince 74 aide à ce retrait   et   au maintien du ressort en position libérée pendant le prélèvement de l'appareil. 



   La figure 13 illustre   l'action   de la pince 72 quand le bras extérieur 89 se rétracte vers l'intérieur dans la direc- tion du bras intérieur 90 au cours de l'assemblage de l'appareil dans   l'orifice;   Cette figure illustre également un autre type d'orifice de réception de l'appareil. Dans ce cas, l'orifice dans le dessus de paillasse   24B   possède un bord rectiligne 96. 



  Aucune bande de clouage et aucun bourrelet n'est prévu. La force de pincement est appliquée directement .contre le coin intérieur 
92 de l'orifice. L'espace déterminé 94 entre le bord 96 de l'o- rifice et l'élément de retenue 76 a été réduit au minimum de façon à assurer la puissance de pincement désirée. 



   La figure 15 montre comment cette variante de pince 
74 peut être avantageusement utilisée pour le montage de parois de fours. Dans ce cas, le rebord 166 du bord du four   107   vient au contact de la surface 105 autour de l'ouverture 109 de la d 

 <Desc/Clms Page number 10> 

 paroi 114. La paroi interne 120 du four 107 possède de petits trous 118 placés de façon appropriée vis-à-vis de la cambure 82 de la pince 74. De cette façon le four ou appareil   sembla-   ble peut être aisément extrait pour son nettoyage ou sa répa- ration simplement en ouvrant la porte 108 et en libérant la pince 74 en repoussant un clou 116 dans le petit trou 118 de facon à presser sur le ressort 74 dans la zone de la cambrure 82.

   Cela libère le bras intérieur 90 du ressort 74 et la force de coincement contre la surface 72 de la pince provoque le   re-        trait de celle-ci en position déverrouillée. La figure 15 illus- tre également un autre type 110 de bande dirigée vers l'inté- rieur, représentée. place par des vis 112. Un autre type d'élément de retenue104 est également représenté, convenant mieux pour des fours ou installations semblables. 



   Dans les divers modes de réalisation représentés, la pression de pincement du ressort est relâchée par décrochage du bras interne des pinces depuis leur position normalement ver- rouillée dans l'élément de retenue de ressort.   On peut   rapide- ment replacer les pinces, prêtes pour une réinstallation en les poussant simplement à leur position verrouillée initiale dans l'élément de retenue. 



   La description qui précède permet donc de constater que la présente invention atteint les buts énumérés précédemment. 



   Les divers modes de réalisation décrits et représen- tés à titre illustratif n'en constituent cependant pas des limi- tations, et de nombreuses autres variantes pourront en être con- çues et elles rentreront dans le cadre de cette invention.

  "Self-adjusting freedom mounting structure", -

 <Desc / Clms Page number 2>

 
The present invention relates to the mounting of peripheral-rimmed appliances, such as sinks, storage units and the like, in countertops, partitions or cabinets and / or to panel mounting: or removable sections of appliances. , walls or cabinets.



   More particularly, it relates to a self-adjusting and self-locking mounting structure or device. for tight fixing of the device or panel in its fixed position. device is quickly releasable for removal of the unit when necessary, without the aid of screwdrivers or other tools usually required for installations of this type.



   Manufacturers of appliances such as sinks and storage units, and those who install such units, have long felt the need for a simple device that reduces the time required for installation and eliminates time-consuming assembly work. screw type. Screw-type clamps generally require the removal of the countertop, cabinet or fixture that is almost permanently attached to the cabinets for the placement of the appliance, or else the work of the operator. installer under considerable discomfort inside the cabinet.



   Even in the latter case, the device is not correctly placed due to the difficulty of placing and clamping; suitably such screwed devices when the installer is in such a position.

 <Desc / Clms Page number 3>

 



   The objects of the invention are therefore as follows: to provide a mounting structure which applies in a favorable manner. fit the edge of the apparatus against the mounting surface so as to form a tight seal; providing an assembly device reducing the time and labor required for the installation of an apparatus; -provide a device that can be placed in a factory-fixed position or in a location far from the reception opening of the device and which remains in the appropriate location on the unit following assembly and / or removal repeated unit; - provide a structure that can be installed in a counter or appliance base without the need to access inconvenient spaces under counters or behind openings;

   - provide a mounting structure allowing rapid release of the pinching force for removal of the device when necessary; .provide a structure eliminating the necessary controls with the screwed assemblies, and thus reducing the risk of damage to the varnishes; or deformation of the edges, etc., often caused by awkward adjustments of the screws of other assembly; - A means of quickly and accurately replacing the pinching device after removal from the device, which
 EMI3.1
 allows rapid reinstallation;

   - -provide a structure flexible enough to automatically adjust to the normal variations of the diametric tolerances of the orifices of the apparatuses while maintaining the ac-

 <Desc / Clms Page number 4>

 nip and tight joint of the structure; - provide a mounting structure meeting all the needs of minimum installation time, tight seal action, sufficient flexibility to automatically adjust to the size of the orifice, which eliminates the adjustments of the screwed systems, which is easily released for the removal of the device, which remains in the correct location after release and removal of the device,

   and which can be easily and quickly replaced with a view to reassembly in the orifice provided for the apparatus.

   Referring in more detail to Figure 1, there is shown a conventional type bench 10 in which an opening is intended to receive a conventional sink 12. The outer edge of the rim of the sink is wider than the orifice. bench and meets the top of the bench surface.



  A number of clips 14 shown in dotted lines are distributed along the edge of the device.



   Figure 2 shows a channel-shaped spring retainer 16 attached to the ledge 18 of the sink. The outer edge 20 of the rim 18 of the sink bears against the surface 22 of the bench 24. A customs strip 26 is shown against the inner edge 30 of the orifice of the apillasse 24.



  It is possible to avoid this band in certain types of installations. Other models in which this band does not fit

 <Desc / Clms Page number 6>

 gure not are shown in Figures 7,10 and 13. The main function of the nailing strip shown here / to allow greater variations in the size of the orifce by ensuring a uniform distance from the top face 22 of the bench 24 to the pressurized pinch area 34 of the spring 32.



   Spring 32 is shown in FIG. 2 in the locked position. In this position, the portion 34 of the spring
32 is wedged against the sole 28 of the nailing strip 26.



   The intermediate portion 36 of the spring 32 is received in a groove 38 formed in the spring retainer 16.



   The two hooked ends 40 of the spring 32 are inserted into slots or grooves 42 of the element 16. In this position the hooked ends are locked in the retaining element, keeping the spring firmly in position. .



   Figure 3 is a view showing the same assembly as Figure 2, but with the spring in the released position. In this case, the two arms 44 of the spring have been pushed back slightly. together which frees the hooked ends 40. It is understood that at this moment the gripping force of the portion
34 of the spring, wedged against the band 26, causes the spring to pivot on its intermediate portion 36 and the upward sliding of the arms 44 in the notch 42 of the retainer 16. When / The spring rotates in this way, the portion 34 of the spring is spaced from the edge 26 of the strip 26, which releases the pinching action and allows removal of the device without difficulty.

   Camholes 46 are provided in the arms of the spring; so that the latter remains in the released position while removing the device.



     It will be noted that the release of the clamping of the spring results quickly from a pressure of the arms 44 between the thumb

 <Desc / Clms Page number 7>

 and index finger and that no screwdriver or other instrument is needed to release or adjust the pressure of the device.



   Figure 4 clearly shows notch 42 viewed from below of retainer 16 and how the hooked ends of arms 44 of spring 32 engage with notch 42.



  It is understood that the channel-shaped retaining element 16 may be made in the form of a long channel cooperating with several springs over its entire length or else that it may be desirable in certain cases to have a separate retainer for each spring.



   Figure 5 shows the separate spring, allowing a clear view of the intermediate portion 36 which slides and pivots in the groove 38 of the retainer 16.
 EMI7.1
 



  Figure 16 illustrates the action of the spring when the apparatus is forced into the orifice. The edge 20 of the rim 18 of the apparatus does not yet touch the top 22 of the bench 24, When the bump 48 of the spring passes over the edge 28 of the strip 26, the intermediate portion 36 of the spring is pushed into the groove 38 of the retainer 16. When the boss 48 has passed the edge 28, the spring tension pushes the inclined portion 34 of the clamp 32 outward, wedging it tightly against the edge of the nailing strip 28 as shown in Figure 2. Its action therefore ensures automatic adjustment to normal dimensional tolerances with great flexibility and maximum pinch pressure.



   FIG. 7 illustrates a variant of the same general principle. A spring retainer 52 is attached to a panel 50 and held tightly against an angle member 56 of an apparatus by means of a spring 58. Here again, the door.

 <Desc / Clms Page number 8>

 tion 64 of the spring is placed in a groove 54 of the element 52.



  The hooked ends 62 of arms 66 of spring 58 are anchored in slots in portions 68 of element 52.



   Figure 8 illustrates the hooked ends 62 in the released state, the spring 58, having pivoted around its intermediate portion 64, having released the pinching pressure of the zone 60 on the edge 70 of the angle bar 56. The panel is ready. to be removed.



   Figures 9, 10 and 11 are views of a variant of the clamp made of flat elastic material instead of metal wire. The retainer mounted under the rim 18 is also different. The modified clip and retainer are designated 74 and 76, respectively. For clarity, clip 74 is shown separately in Figure 12 and Figure 14 shows the modified retainer 76 viewed from 14- 14: of figure 13. '
In the clamp 74 a notch 78 provided to ensure the desired flexion of the clamp in this bent zone. The clamp has a surface 84 at the desired angle to properly guide the apparatus into the orifice.



   Figure 12 shows the clamp 74 which has an outer arm 89 notched along 88 and an arm 90 with a slot 86.



   It is of course that the edges 98 of the opening 102 of the retaining element 76 (see FIG. 14) are such that they slide into the notches 88 of the clamp 74. The projection 100 in the opening. Spindle 102 of element 76 fits into slot 86 of inner arm 90 of gripper 74 during placement and when gripper 74 is in the normally locked position of threads 9 and 10.



   Referring to Figures 9, 10 and 11, we see. that the modified bench 24A has / a bead 80. The surface

 <Desc / Clms Page number 9>

 inclined 72 of the clamp 74 ensures a wedging against the internal edge of the bead 80, The bead 80 therefore the same purpose as the nailing strip 26 of Figures 2, 3 and 6, and it allows notable variations in the dimension of the receiving hole! Ion of the apparatus by ensuring a uniform spacing between the upper surface 22 and the inner edge of the bead 80 against which the angle 72 of the spring 74 wedges in the manner of a wedge.



   It is understood that in this variant, when the inner arm 90 of the spring 74 is slightly pushed back towards the outer arm 89, the slot 86 of the clamp 74 is released from its normally locked position on the portion 100 of the notch. 102 of the retainer 76. When the inner arm is thus released, the pinching force of the slope 72 of the clamp 74 against the inner edge of the hole causes the inner arm 90 to move to the position. unlocked shown in Figure 11. The notch 82 of the clamp 74 helps this withdrawal and maintaining the spring in the released position during removal of the device.



   Figure 13 illustrates the action of clip 72 as outer arm 89 retracts inwardly in the direction of inner arm 90 during assembly of the apparatus in the port; This figure also illustrates another type of orifice for receiving the apparatus. In this case, the hole in the bench top 24B has a straight edge 96.



  No nailing tape and no bead is provided. The pinching force is applied directly against the inside corner
92 of the orifice. The determined space 94 between the edge 96 of the port and the retainer 76 has been minimized to provide the desired clamping power.



   Figure 15 shows how this variant of gripper
74 can advantageously be used for mounting oven walls. In this case, the rim 166 of the edge of the furnace 107 comes into contact with the surface 105 around the opening 109 of the d
