Definitions

  • This invention refers to a pin joint for an adjustable spotlight, with innovatory assembling features.
  • the scope of this invention is to provide a restricted pin joint which, although it is inside the body of the spotlight, does not necessarily require the latter to be opened in order to fasten it and which moreover can be fastened quickly and reliably without the need for special tools.
  • a pin joint for an adjustable spotlight in which a support comprises aligned lateral pins each of which fits into a housing in the body of the spotlight for restricted rotation, characterized by the fact that a leaf spring is centrally bent to embrace at least more than half the circumference of the pin to form the housing thereof and branches off into divaricated arms received by an aperture in the body whose edges engage with the ends of the arms in order to bring them together and tighten the housing around the pin.
  • a spotlight 10 with swivel joint made according to the invention, comprises a supporting arm 11 having close to one end two half pins 12, 12′ disposed on opposing sides.
  • the opposite end of the support 11 is not shown since it can be made with securing means of any known type, such as for example a plate for securing it to a wall by means of screws, a spring clip, etc..
  • the body 20 of the spotlight has a slot 13 to slidingly receive the joint end of the supporting arm 11.
  • Said slot has two lateral apertures 14 and 15 at right angles to its longitudinal direction.
  • the half pins 12, 12′ are fitted with two spring elements 16, 16′, respectively, (only the elements of the spring 16 will be hereinafter referred to, it being understood that the spring 16′ is identical and that its component parts have the same reference numbers as the corresponding parts of the spring 16, but with the suffix ').
  • the spring elements are generically "V"-shaped with a semi-cylindrical central portion 17 with a diameter substantially similar to that of the half pins and with a semi-circumference larger than half the circumference of the half pins.
  • the free ends of the elements 16 are shaped to form two grooves 18 and 19 extending towards each other with a width substantially equal to the thickness of the edges of the two lateral apertures 14 and 15.
  • the divergence of the two arms of one spring 16 is such that the distance between the two grooves is greater than the distance between the two opposing edges of each aperture 14 and 15.
  • the support is fitted onto the spotlight by positioning the spring elements on the half pins and inserting the end of the support into the slot 13 so that the two spring elements are compressed and slide into the two apertures 14 and 15 until the grooves 18 and 19 snap onto the opposing edges of said apertures, as can be clearly seen in figure 2.
  • the latter can be orientated in a plane perpendicular to the pins with a maximum angle depending upon the length of the slot 13 in which the support 11 slides, as can easily be imagined by the technician.
  • the springs 16 must obviously be of such dimensions as to support the weight of the spotlight, both in terms of the load that the arms can withstand without becoming distorted, and in terms of thrust exerted by the grooves 18 and 19 on the edges of the apertures 14 and 15.
  • any force exerted on the support, in order to remove it from the body of the spotlight in the coupling direction gives rise to components which, due to the propensity of the pins to wedge themselves in the open portion of the semicylinders 17, tend to force the grooves of the springs even harder against the edges of the apertures.
  • FIGS. 4 and 5 schematically show a second possible embodiment of such coupling, in which the ends of the springs 16, instead of being shaped with grooves, are made with two lateral slits which engage with two corresponding ledges 23 and 24 disposed on opposing edges in the apertures at the sides of the slot through which the support slides.
  • the ends of the springs can be made with gripping extensions protruding from the body of the spotlight so as to enable it to be disassembled more easily.
  • the shape of the body of the spotlight with its slots for the supporting arm and the shape of the support itself are given herein for descriptive convenience, it being understood that they may be of any desired shape in order to satisfy particular aesthetic or practical criteria.
  • edges onto which the ends of the springs engage may be recessed in the body of the spotlight so that, once they are engaged, the springs cannot be seen from the outside. It is thus also posssible to hide the ends of the springs completely, by not offering the possibility of easily separating the parts.
  • the grooves at the ends of the springs can be shaped and orientated differently according to the particular design of the slot for sliding the support into the body of the spotlight and the shape of the edges of the lateral apertures, as is easily imaginable by the technician.
  • the ends of the springs can also be simply bent to fit into grooves or recesses made on the edge of the apertures.
  • the springs advantageously engage by means of a sliding movement it is also possible for them to be secured in position by manually pressing the two arms and subsequently fitting them in place.
