Definitions

• the present invention relates to the technical field of home and office electric systems, and more particularly, relates to a fixing clip for wall mounting of an electric apparatus .
• electric apparatus means, in general, any means or electric device generally part of electric equipment in civil building and the like and usually destined for mounting, for instance embedded, onto such building walls.
• circuit breakers electric network piugs, data network plugs, TV plugs, phone plugs, buttons, circuit breaker, switches, general electric, control devices, connectors, thermostats, timers, fuse boxes, alarms/buzzers, emergency lamps for instance removable ones, signaling lamps for instance step signaling ones, displays, for instance LCD's and the like.
• cover plate removably fixable to the frame and provided with an opening that allows a user to access, visually or manually to the electric apparatuses installed on the support frame.
• Some specific electric apparatus types are also known, named single-blocks, wherein a plate and the electric apparatus itself are substantially integrated in a single piece and are fixed directly to the wall embedded box without requesting a suitable support frame .
• the present invention aim is to make available a fixing clip that allows overcoming above described shortcoming of the known art .
• FIG. 1 is a perspective view and with detached parts of a set of parts for an electric apparatus wall mounting
• figure 2 depicts a side view of a support frame comprised in figure 1 parts set;
• FIG. 3 depicts a fixing clip according to a particularly preferred embodiment of the present invention.
• FIG. 1 a frame-box part set perspective view is depicted, generally indicated as 1.
• the frame-box part set 1 comprises a support frame 2 and a wall embeddable box 3.
• Box 3 that only by way of example has been depicted in a cylindrical shape, is in practice a container provided with an inner receiving space and comprising an inner container wall 30 bounding such inner space. Said container is commonly realized in anti-impact resin and has standard dimensions .
• Support frame 2 comprises a frame shaped body 4, having approximately a shape of a substantially plate-shaped frame, for instance, non limiting, of a quadrangular layout with rounded corners. Only by way of example, the support frame 2 frame body 4 was depicted of a substantially square shape.
• the support frame 2 frame body 4 develops itself around a mounting window 5, defining a mounting seat adapted to receiving or holding one or more electric apparatuses, not shown in figures.
• Such latching members 7 are such to cooperate with corresponding latching members provided of opposite sides of electric apparatuses to be latched to support frame 2.
• latching members 7 allow to connect electric apparatus to support frame 2 with a notching and snap joint.
• Support frame 2 comprises, further, fixing means 10, 11 for removably fixing the support frame 2 to the wall embeddable box 3.
• fixing means comprise, advantageously, fixing clips 11, or straddling members 11, and comprise adjustment screws 10 cooperating with such fixing clips 11 to vary . progressively a slope angle ⁇ (visible in figure 2) defined between such clips 11 and support frame 2.
• adjustment screws 10 are such to go through respective holes 13 provided in support frame 1 to insert in a suitable threaded cavity 22 provided in a respective fixing clip 11.
• support frame 2 includes a pair of fixing clips 11 associated with respective adjustment screws 10 and located on respective opposite sides of support frame 3 frame body 4.
• fixing clips 11 have a structural arrangement such that tightening adjustment screws 10 one may vary an slope angle ⁇ defined between fixing clips 11 and support frame 2 frame body 4, until reaching a latching configuration wherein fixing clips 11 engage the box inner walls to secure support frame 2 to wall embeddable box 3.
• a fixing clip 11 particularly preferred embodiment according to the present invention is shown in greater detail in figure 3.
• such fixing clip 11 is realized in a dye cast metal.
• such fixing clip 11 is realized by a dye forming technique wherein dye filling is achieved exerting a high pressure on molten metal.
• dye forming techniques by dye casting are known to the man skilled in the art and therefore will not be described in more detail .
• clip 11 is realized in zama, that is in practice a metal alloy with a high zinc content comprising small amounts of copper, aluminum and magnesium.
• fixing clip 11 shows a minimum thickness approximately greater than 1,5 mm, preferably equal to approximately 2 mm.
• Such clip includes a base portion 20 having a seat surface 21 adapted to interfere with a corresponding surface portion defined onto support frame 2 body 4.
• the base portion 20, that is preferably conformed as a small bar, further includes a substantially cylindrical and inner threaded channel 22 having an opening defined on seat surface 21.
• Such channel 22 crosses base portion 20 as well as the channel opening defined on seat surface 21 allows channel 22 to be able to receive within itself adjustment screw 10 cooperating with fixing clip 11.
• seat surface 21 is a substantially planar surface laying on a plane substantially perpendicular to channel 22 extension direction z, that in practice is adjustment screw 10 screwing direction z.
• seat surface 22 slopes progressively with respect to support frame 2 frame body 4 moving to reach a position wherein such seat surface 21 is facing and parallel to a corresponding surface defined upon support frame e frame body 2.
• Mounting clip 11 further includes at least a claw 24, or a jawed portion, formed by a small bar 25 having a first end radiused to base portion 20 and a second opposite end provided with a projecting tooth 26 adapted to penetrate at least partially inside inner wall 30 of the embedded box 3.
• a projecting tooth 26 is substantially conformed as a square base pyramid, or a rectangular base, or a tapered base one .
• mounting clip 11 includes, in particular, two clawed portions 24 that depart from base portion 20 and are spaced between themselves.
• a reinforcement cross bar 27, different from base portion 20, is provided in fixing clip 11, between two clawed portions 24.
• such reinforcement bar 27 is near the clawed end portions 24 distal from base portion 20.
• a fixing clip 11 according to present invention is able to guarantee a considerable hold in fixing wall box 3 support frame 2, overcoming in this manner known art fixing systems shortcomings.
• a fixing clip 11 according to the present invention guarantees a 20% higher hold as compared to known art clips made of punched iron sheet .
• fixing clips 11 are used to fix a support frame 2 to the wall box 3 such clips 11 may also be used advantageously to fix an electric apparatus, for instance a single-block type, directly to wall embedded box 3, that is, without using support frame 2.
