Description

Technical Field

[0001] The present invention relates to a control and / or signaling component including a fixed device. Background Art

[0002] Electrical control and / or signaling components used in industry, such as buttons, emergency stop buttons, and indicator lights, are designed to be fixed through openings in the wall (e.g., the panel of a distribution panel or the door of an electric control console).

[0003] The control and / or signaling components include a tubular body that can be engaged in an opening in the wall and has a collar that abuts against the outer surface of the wall.

[0004] Fixtures allow components to be secured to an opening by abutting against the interior surface of a wall. Fixtures typically include a base, which can be assembled from the interior surface of the wall to the body using assembly devices.

[0005] The base is adapted to receive at least one electrical block and a fixing device, the fixing device being adapted to abut against the inner surface of the wall to hold the component against the wall.

[0006] Such fixing devices have been disclosed in FR 2735274, WO 91 / 07790, FR 2654266 and EP 0889564. In these prior art devices, the base may include three-point fixing elements. However, these fixing devices are generally complex and therefore expensive to manufacture.

[0007] For simplicity, the base may consist of only two fixing points, and then typically two screws are used to pass through the holes in the base and abut against the inner surface of the wall.

[0008] However, the fixing devices must adhere to certain size limitations. In fact, such as... Figure 1 As shown, in order to maintain compatibility with the control and / or signal components most commonly installed today, the vertical distance D1 between the axis of the first control and / or signal component and the axis of the second adjacent control and / or signal component must be approximately 30 mm, and the horizontal distance D2 between the axis of the first control and / or signal component and the axis of the third adjacent control and / or signal component must be 40 mm.

[0009] These limitations can be easily overcome by using a fixing device with three-point fixing elements.

[0010] These limitations are more difficult to overcome using fasteners with only two points of fixation, because these two points of fixation need to be aligned with the center of the base, which in turn requires a larger base size in the alignment direction.

[0011] However, these limitations can be overcome by a fixing device with only two fixing points, for example, as disclosed in patent application FR1853091, in which the base includes a plate having a curved portion with holes for receiving attachment latches for electrical blocks. Thanks to the curved portion of the base, it is possible to use a two-point fixing device by using screws, while allowing multiple electrical blocks to be received on the same base.

[0012] While such a base may be satisfactory, it requires a complex design, which can be difficult to manufacture and expensive.

[0013] Therefore, there is a need for a fixing device, particularly a fixing device with two fixing points, which ensures reliable fixing of control and / or signal components through a wall, and in particular, which can maintain a minimum distance D1, D2 between two adjacent control and / or signal components on the wall. Summary of the Invention

[0014] The present invention improves this situation.

[0015] This invention provides a control and / or signaling component suitable for insertion into an opening through a wall, the component comprising:

[0016] - Activate the button, which is adapted to convert the user's input into at least one translational and / or rotational motion;

[0017] - A base adapted to secure the component to a wall, the base having an opening in the main direction adapted to receive an activation button;

[0018] - To receive at least two electrical control and / or signal blocks on the base, wherein the at least two electrical control or signal blocks include:

[0019] -A central electrical control and / or signal block facing the activation button in the main direction;

[0020] - At least one lateral electrical control or signal block, which is adapted to be placed next to the central electrical control or signal block.

[0021] The central electrical control or signal block is suitable for actuation via the following:

[0022] - Lateral electrical control or signal block; or

[0023] - Rotational motion from the activation button.

[0024] Thanks to this arrangement, no translational force is applied directly to the central block. Therefore, locking devices are not required in the central portion of the base for secure attachment. Consequently, these locking devices can be relatively small, leaving more available space for the fasteners, thus meeting the overall component size constraints.

[0025] The following features can be implemented selectively, individually, or in combination:

[0026] The central electrical control or signal block and the lateral electrical control or signal block are two different blocks.

[0027] The central block is a single-signal block. The signal block can be advantageously actuated electrically in an indirect manner, rather than mechanically actuated by activating a button.

[0028] The lateral electrical control or signal block includes a first locking device to be received on the base, and the central electrical control or signal block includes a second locking device to be received on the base; the first and second locking devices are different from each other. The lateral electrical control or signal block can be mechanically actuated by an activation button, but it cannot be removed when subjected to force from the activation button due to the action of the first locking device.

[0029] The base includes a first receiving device and a second receiving device (34) to receive the first and second locking devices, respectively.

[0030] The central electrical control or signal block and the lateral electrical control or signal block form a dual block.

[0031] The central block is the control block of the two blocks.

[0032] The central electrical control or signal block and the lateral electrical control or signal block include receiving devices on the rear face to allow at least one additional electrical control or signal block to be added by stacking them on the base.

[0033] The base is made from a single component made of metal or plastic material.

[0034] The base has a parallelepiped shape and includes a first symmetry plane and a second symmetry plane, which are orthogonal at the center point.

[0035] The base has a first fixing hole and a second fixing hole, which are screwed onto the wall by a fixing device, and the second receiving device is aligned with the first and second holes.

[0036] The base includes a metal-made reinforcing region surrounding the first and second orifices.

[0037] The central block includes a lateral surface with an inclined side to allow for an inclined passage for tools used to manipulate the first and second fixing screws located in the first and second fixing orifices, respectively.

[0038] Each of the first and second fixed orifices is inclined relative to the main direction.

[0039] The base is suitable for assembly to the body of the component via a mechanism having elastic springs and contact elements. Attached Figure Description

[0057] The accompanying drawings and the following detailed description essentially contain some specific elements. They can be used to enhance the understanding of this disclosure and, if necessary, to define the invention.

[0058] Control and / or signal components

[0059] Now refer to Figure 2 and Figure 3 It shows control and / or signal component 1 (hereinafter referred to as "component").

[0060] In a non-limiting manner, component 1 can be a button, knob, indicator light, emergency stop button, illuminated button, illuminated knob, etc.

[0061] Component 1 may include control functions by activating one or more electrical signals, or signal functions by turning one or more lights on / off. Other functions are possible.

[0062] Component 1 is adapted to engage with a circular opening 5 via a wall 2, such as the door of an electrical cabinet, the panel of an electrical distribution panel, or a control console.

[0063] Opening 5 can advantageously have a standard diameter, for example, equal to 22 mm or 25.5 mm.

[0064] When engaged in opening 5, component 1 extends in the principal direction X. The principal direction X corresponds to the axis that traverses opening 5. Wall 2 and opening 5 extend in a second direction Y perpendicular to the principal direction X. Wall 2 defines an outer surface 2a and an inner surface 2b on opposite sides of an intermediate plane P, which includes the second direction Y.

[0065] Component 1 includes an activation button 6, which is adapted to convert user input into rotational and / or translational motion.

[0066] Component 1 also includes a tubular body 10.

[0067] The body 10 is adapted to be inserted into the opening 5 through the wall 2. The body 10 includes a collar adapted to surround the activation button 6. The collar forms a shoulder 100 that abuts or adjoins the outer surface 2a of the wall 2 around the opening 5. The body 10 may be made of metal or plastic material.

[0068] The fixing device 12 allows the component to be fixed to the opening 30 by abutting the inner surface 2b of the wall 2.

[0069] base

[0070] The fixing device 12 includes a base 3. For example... Figure 4 As shown in more detail, the base 3 has a parallelepiped shape. The base 3 includes a first symmetry plane S1 and a second symmetry plane S2, which are orthogonal at the center point O.

[0071] The base 3 also includes a front surface 3a and a rear surface 3b that are parallel to each other. The front and rear surfaces 3a and 3b are substantially flat.

[0072] By referring to the "front and rear faces," it should be understood that the front face 3a is relatively closer to the inner face 2b of the wall 2 compared to the rear face 3b, which is located relatively far away when the base 3 is assembled onto the main body 10. Subsequently, the front face 3a and the rear face 3b of the base 3 are perpendicular to the main direction X and parallel to the intermediate plane P.

[0073] Reference Figure 4 The base 3 has a central circular opening 30, which has a diameter suitable for the body 10 of the component 1 to pass through.

[0074] The base 3 is adapted to be assembled to the body 10. The base 3 can be secured to the tubular body 10 by interlocking, capturing, using a bayonet mechanism, or by any other assembly device.

[0075] Component 1 also includes a fixing device suitable for fixing the base 3 to the wall 2.

[0076] More precisely, the base 3 can be screwed onto the wall 2. For this purpose, the base 3 has a first fixing hole 31 and a second fixing hole 32, such as... Figure 4 As shown.

[0077] The first and second fixing holes 31 and 32 are located on opposite sides of the opening 30 of the base 3 and the second symmetry plane S2, while the first and second fixing holes 31 and 32 belong to the first symmetry plane S1.

[0078] like Figure 2 As shown, the fixing device includes a first fixing screw 50 to be screwed into a first hole 31 and a second fixing screw 51 to be screwed into a second hole 32. The ends of the first and second fixing screws 50, 51 are adapted to abut against the inner surface 2b of the wall 2. The tightening range allows it to be adjusted relative to the thickness of the wall 2. When the base 3 is assembled to the main body 10, the front surface 3a and the rear surface 3b of the base 3 are substantially parallel to the intermediate plane P.

[0079] According to the embodiment, each of the first and second fixing holes 31, 32 can be tilted relative to the main direction X. Therefore, during tightening, the first and second fixing screws 50, 51 are tilted towards the main direction X, such that these first and second fixing screws 50, 51 reach the inner surface 2b of the wall 2 directly or almost directly below the shoulder 100 of the body 10. This prevents deformation of the wall 2, especially when the wall 2 is particularly thin.

[0080] Electrical control and / or signal blocks

[0081] Base 3 is designed to receive one or more electrical control and / or signal blocks 4a, 4b, 4c (hereinafter referred to as “blocks”).

[0082] More precisely, the base 3 is adapted to receive a central block, which is received at the center of the base 3. The base 3 is also adapted to receive at least one lateral block, and advantageously, two lateral blocks are received on the lateral portions of the base 3.

[0083] The phrase "in the center of the base" should be understood as referring to the central block facing the activation button 6 in the main direction X. Conversely, the phrase "in the side portion of the base" should be understood as referring to the side blocks not facing the activation button 6, but located on the side of the base 3 or along the edge of the base 3, i.e., off-center from the center point O in the second direction Y.

[0084] Subsequently, the central block and the lateral blocks are placed adjacent to each other perpendicular to the second direction Y and the intermediate plane P. Component 1 can therefore include one, two, or three adjacent blocks 4a, 4b, 4c, as described below. When three adjacent blocks are included, the central block is sandwiched between the two lateral blocks.

[0085] The lateral block can be control block 4a, such as Figure 3 As shown. Control block 4a is adapted to command one or more electrical signals. Control block 4a can be of normally open (NO) or normally closed (NC) type.

[0086] like Figure 5A and Figure 5B As shown, the control block 4a includes a parallelepiped-shaped housing 40 made of insulating material. Additionally, the control block 4a includes a front surface 41 and a rear surface 42 that are opposite each other.

[0087] The front surface 41 is adapted to be adjacent to and abut against the outer surface 3b of the base 3.

[0088] The control block 4a includes an actuator 43 protruding from the front face 41. The actuator 43 may be translationally and / or rotatably movable. The actuator 43 is electrically connected to contacts (not shown) inside the housing 40, which can control electrical signals.

[0089] The activation button 6 of the activation component 1 is activated by moving the actuator 43, for example, by applying force to the actuator 43 along the main direction X or by applying a rotational force to the actuator 43 about the main direction X, thereby moving the movable contact of the block.

[0090] Advantageously, the central block can be signal block 4b, such as Figure 2 As shown. Signal block 4b is suitable for emitting optical signals. (As illustrated...) Figure 6 As shown, similar to control block 4a, signal block 4b includes a parallelepiped-shaped housing 60 made of insulating material. Additionally, signal block 4b includes a front face 61 and a rear face 62 that are opposite each other.

[0091] like Figure 6 As shown, signal block 4b includes a light emitter 63 protruding from the front face 61. The light emitter 63 can be of any type, such as a light-emitting diode. For this purpose, the activation button 6 can be at least partially transparent or translucent, so that light passes through the wall 2 in the direction of the user.

[0092] The activation button 6 of the activation component 1 can turn the light emitter 63 on / off so that the user can see the light. For this purpose, the central block 4b can be electrically actuated independently of the force applied by the user in the main direction X. The central block can also be actuated by means of the side blocks.

[0093] According to an embodiment, signal block 4b may include a lateral surface having inclined sides 65, 66, thereby allowing an inclined passage for tools used to manipulate fixing screws 50, 51 located in the first and second fixing holes 31, 32, respectively.

[0094] The lateral blocks and the central block include different locking devices, thereby allowing them to be received on the base 3. Moreover, the base 3 includes at least two different types of complementary receiving devices to receive different types of lateral or central blocks.

[0095] like Figure 5A and Figure 5B As shown, the lateral blocks, such as control block 4a, include first locking devices 44, such as hooks or latches, advantageously located at both ends of the front face 41. These first locking devices 44 can elastically deform to snap into two first receiving devices 33, such as holes, in the base 3. The holes 33 are advantageously located at each corner of the base 3, facing each other with respect to the planes of symmetry S1 and S2.

[0096] like Figure 6 As shown, the central block, such as signal block 4b, also includes second locking devices 64, such as hooks, advantageously located at both ends of the front face 61. The two second locking devices 64 can elastically deform to snap into the second receiving device 34 of the base 3, such as a ridge. The ridge 34 is advantageously located on the contour of the opening 30 of the base 3. The ridge 34 is aligned with the first and second apertures 31, 32 of the base 3 and the center point O. The ridge 34 is closer to the center point O than the aperture 33.

[0097] Although not described, other types of locking and receiving devices are also possible, such as resilient attachment elements mounted on springs, etc.

[0098] The first locking device 44 and the first receiving device 33 of the lateral block are adapted to securely hold the lateral block to the base 3. The first locking device 44 needs to be robust enough to ensure that the lateral block cannot separate when a translational or rotational force is applied to the pusher 43. This is especially true when the user applies a force to the pusher 43 in the main direction X.

[0099] Furthermore, the first receiving device 33 is adapted to hold the lateral block when a rotational force is applied perpendicular to the main direction X. The base 3 may also include an additional recess 36 to increase structural support. The recess 36 complements the protrusion 37 located on the front surface 41 of the lateral block, such as... Figure 7 As shown.

[0100] Although the second locking device 64 and the second receiving device 34 of the central block are equally adapted to hold the central block fixedly to the base 3, the attachment can be relatively weak because no force is applied directly to the central block along the main direction X when the button 6 is activated. Only an indirect electrical actuation or rotational force from the lateral blocks is applied. However, even with the relatively weak attachment to the second locking device 64, this rotational force or electrical actuation cannot separate the central block from the base 3.

[0101] Furthermore, compared to the first locking device 44, the second locking device 64 needs to be less robust and therefore has a smaller size. This allows for increased compactness, enabling additional space to be used for the fixing device. In this way, the size constraints of component 1 are resolved.

[0102] Double block

[0103] As described above, according to the present invention, a block can be a single block, but according to the present invention, it can also be multiple blocks. Advantageously, a block can be a pair of blocks.

[0104] The use of "single / multiple" indicates that a block can have a single or multiple functions, particularly a single control and signal block 4a, 4b as described above.

[0105] like Figure 7 As shown, the dual block 4c can contain two blocks, such as two control blocks 4a fixedly attached together, so that the dual block 4c forms a single element.

[0106] Although the block has multiple functions, it only includes two first locking devices 44, which are received on the lateral portion of the base 3. This avoids having the second locking device received in the center of the base 3. Therefore, more space is provided for the fixing devices to tighten the base 3 onto the wall 2. Even with only two fixing devices, size limitations can be easily overcome.

[0107] like Figure 8 As shown, when the two blocks 4c are received on the base 3, the two control blocks 4a correspond to the lateral block and the central block, respectively. Although in Figure 8 It is not shown in the figure, but another lateral block can be received on the base 3 at a position adjacent to the double block 4c.

[0108] like Figure 7 As shown, the multi-block also includes a single actuator 43. Actuator 43 can move between several positions to command multiple functions of the multi-block simultaneously or at different times. Actuator 43 advantageously belongs to the lateral blocks of the double block 4c. Thus, the central block can be activated via the lateral blocks.

[0109] For example, when the activation button 6 is rotated, the actuator 43 can move. Clockwise rotation of the activation button 6 moves the actuator 43 to one position along the second direction Y. Subsequently, the actuator 43 can emit an electrical signal. Counterclockwise rotation of the activation button 6 moves the actuator 43, which has moved in the second direction, to another position along the second direction Y. Subsequently, the actuator 43 can emit another electrical signal. Translational movement of the actuation button 6 can also move the actuator 43 to another position along the main direction X.

[0110] Block stacking

[0111] According to an embodiment, each control block 4a may have a receiving device 45 on its rear face 43 to allow for, Figure 8 As shown, another block is added by stacking. These receiving devices 45 are the same as or similar to the first or second receiving devices 33, 34 of the base 3. Subsequently, another block is formed relative to the second row of blocks of the base 3, and is fixed to the base 3 by means of the blocks of the first row. The blocks of the second row are fixed to the blocks of the first row in the same manner as they are fixed to the base 3 as described above.

[0112] like Figure 9 As shown, actuating a block in the first row can also actuate one or more blocks in the second row. For example, in this... Figure 9 In the example, the actuator 43, which moves the first row of blocks along the main direction X, can command the electrical signal of the second row of blocks. Due to this arrangement, it is possible to obtain a very compact and modular component 1, while simultaneously achieving a multitude of functions that can be commanded only by activating button 6.

[0113] like Figure 10 As shown, various arrangements of component 1 can then be obtained by using a single control block CB, a single signal block SB, or a dual block 2CB.

[0114] exist Figure 10 In all these arrangements illustrated in the examples, the central block is either a signal block that will not be subjected to force along the main direction X, or a double block. Due to the first locking device 44 and the first receiving device 33 on the lateral portion of the base 3, the double block can be fixedly attached to the base 3 without the need for any additional second locking device and second receiving device.

[0115] Other embodiments of the base

[0116] The base 3 can be made of one or more materials.

[0117] According to the first embodiment, the base 3 can be made of a single material, such as a zinc alloy (Zamak). By using a single material, the thickness of the base 3 can be reduced, particularly along the main direction X, thereby increasing its compactness and robustness.

[0118] Such a base 3 can be adapted to receive one or two blocks that can be screwed onto the base 3. For this purpose, the base 3 may also include complementary receiving holes 35 to receive screws, such as... Figure 4 As shown.

[0119] Alternatively or complementaryly, the same base 3 may also be adapted to receive a block capable of elastic deformation to snap into the base 3. For this purpose, the base 3 may further include a first receiving device 33 and a second receiving device 24, as already described above. Figure 4 As described.

[0120] Due to these different ways of receiving blocks, the base 3 can be used in a modular manner to receive different types of blocks by means of screws or snap-fits.

[0121] According to the second embodiment, the base 3 can be made of two or more materials.

[0122] More precisely, according to Figure 11A and Figure 11B In the embodiment shown, the base 3 may include a metal reinforcing region 38 surrounding the first aperture 31 and the second aperture 32, more specifically a zinc alloy reinforcing region 38, while the rest of the base 3 is made of plastic.

[0123] Furthermore, due to the mechanism 70 having an elastic spring 71 and a contact element 72, the base 3 can be assembled onto the main body 10.

[0124] The elastic spring 71 is a spring-shaped wire made of metal that extends between a first end 73 and a second end 74. Between the first end 73 and the second end 74, the elastic element 71 is U-shaped and has a middle portion 75 that connects to two parallel lateral portions 76, 77.

[0125] The elastic element 71 is mounted in the groove of the contact element 72. The contact element 72, together with the elastic element 71, is adapted to be inserted into the cavity of the base 3 extending from the opening 30. More precisely, the two cavities face each other on each side of the opening 30.

[0126] like Figure 12 As shown, the contact element 72 includes a hook 78 adapted to abut the base 3 so that the contact element 72 cannot be pulled out of the base 3 by translational movement alone.

[0127] like Figure 11A More specifically, the two ends 73, 74 of the elastic element 71 are supported by pins 79 protruding from the base 3.

[0128] The body 10 can be assembled to the base 3 by moving the body 10 along the main direction X within the opening 30 of the base 3. The body 10 pushes away the contact elements 72 by elastically deforming the elastic element 71. Each contact element 72 can thus engage in a complementary cavity 80 of the body 10 to securely hold it to the base 3, as... Figure 13 and Figure 14 As shown. The contact element 72 is spring-biased onto the cavity 80 of the body 10.

[0129] When the main body 10 needs to be removed from the base 3, the user can use a tool 81, such as a screwdriver, to remove the contact element 72 from the main body 10 by applying a force F perpendicular to the opening 30.
