Definitions

  • the present invention relates to a lamp comprising a receiving element for a rotationally symmetrical glass body with a receiving opening, a rotationally symmetrical glass body arranged in this receiving opening and an annular, permanently elastic element arranged between the receiving element and the glass body.
  • Luminaires comprising a rotationally symmetrical glass body and a receiving element with a receiving opening into which the glass body is inserted are widely known.
  • the fixation of the vitreous body in the area of the receiving element is of particular interest.
  • the CH 706 139 A2 a luminaire and in particular a luminaire that is completely watertight with respect to water and water vapor.
  • a light transmission opening is enclosed by an inwardly directed annular end flange which has a circumferential shoulder.
  • the light transmission opening is covered by a disk-shaped glass element which also has a circumferential shoulder on the edge. In the inserted position, the glass element rests with its shoulder on the corresponding shoulder of the connecting flange.
  • a first ring seal in the form of an O-ring is provided in the area of the shoulder.
  • an annular groove is made in the end flange following the step towards the interior of the lamp, in which an additional sealing ring is arranged and seals the joint between the glass element and the end flange.
  • connection of a glass element with an element surrounding it is also known from other areas, for example photography. So describes the WO 2009/000591 a camera lens with a lens frame and a lens accommodated in the lens frame. It is provided here that a positive connection is formed between the outer surface of the lens and the inner surface of the lens mount, for example a projection or a lug is provided on the inner surface of the lens mount, which engages in a groove formed in the lens.
  • a positive locking device such as an O-ring can also be used here.
  • the flashlight comprises an outer housing, in which an illumination section and a lens arrangement are accommodated.
  • the housing itself is from closed with a transparent cover.
  • the lenses are pressed against the top of the housing by means of a spring system, an additional seal being inserted between the uppermost lenses and the outer housing.
  • connection between the frame or end element and the glass body is associated with considerable effort in order to achieve a good fixation of the same.
  • tightness and rattle-free assembly of the elements are expected.
  • the object of the present invention is to provide a particularly simple assembly of a glass body in a receiving element, which can be used for a wide variety of lights.
  • a lamp comprising a receiving element for a rotationally symmetrical glass body with a receiving opening, a rotationally symmetrical glass body arranged in this receiving opening and an annular, permanently elastic element arranged between the receiving element and the glass body, in that the receiving element is designed with a support surface which is inclined towards the glass body, and the glass body is formed with a receiving surface diametrically opposite the supporting surface, the permanently elastic element being positioned between the supporting surface and the receiving surface in the installed state in order to fix the receiving element and the glass body in a form-fitting and concentric manner to one another and that an annular gap is provided between the glass body and the receiving element for introducing the annular, permanently elastic element between the supporting and receiving surfaces.
  • the present invention provides a particularly simple assembly of two components, with particular reference being made to the special properties of the glass body, which often has manufacturing-related tolerances, whereas the receiving elements are usually cast parts that can be manufactured precisely. So far, therefore, complex joining processes have generally been used, for example gluing or precisely manufactured grooves, in order to connect the two elements to one another.
  • connection is achieved via a permanently elastic, ring-shaped element, which fixes the two elements in a form-fitting and concentric manner.
  • the permanently elastic annular element is inserted into the glass body under tension and at the same time presses on the receiving element due to the special design of the annular gap, so that rattle-free assembly can be achieved here. Since the actual connection takes place via the ring-shaped element, tolerances of both elements are essentially irrelevant.
  • the glass body has a light entry surface and a light exit surface, the annular gap being arranged on the side of the light entry surface. Consequently, the connection between the glass body and the receiving element is arranged in the interior of the lamp, so that there is no external access to the connection.
  • the receiving element is designed with a radial inner surface and the glass body with an outer lateral surface, the radial inner surface and the lateral surface being opposite one another in the installed state and the supporting surface in the region of the radial inner surface and the receiving surface is arranged in the area of the lateral surface.
  • the annular gap can be provided by a simple constructive design of the outer dimensions of both elements, without additional manufacturing steps being necessary here. Equally, the provision of the support surface and the receiving surface is also possible without great manufacturing-related effort.
  • the outer surface of the glass body can extend substantially parallel to an outer outer surface of the receiving element and the radial inner surface of the receiving element can be designed to taper conically in the direction of the light entry surface of the glass body. Due to the conical design of the inner surface of the receiving element, it is possible to initially design the annular gap with a wide insertion opening, through which the positioning and insertion of the permanently elastic element is facilitated, and at the same time the conical configuration of the annular gap prevents the permanently elastic element from being removed during the insertion the annular gap, because the decreasing width of the gap already allows a preliminary fixation.
  • the outer lateral surface of the glass body is designed in a stepped manner, the two steps being connected to one another via a contact surface formed perpendicular to the outer lateral surfaces. It can be provided here that the receiving element is in contact with the supporting surface of the glass body in the installed state.
  • the formation of a stepped lateral surface provides a support surface by means of a simple structural measure, which serves on the one hand for the targeted positioning of the glass body in the receiving element and at the same time provides an axial limitation of the receiving element on the side opposite the annular gap.
  • the receiving surface of the glass body can be designed as an annular groove, in particular with a partially circular cross section.
  • An annular groove has proven particularly useful in use, since it provides a particularly good fit for the annular element.
  • the support surface is arranged on an end of the annular gap facing the glass body and has a predetermined curvature on the Vitreous to extend.
  • This embodiment contributes to the fixation of the receiving element by means of the annular element. In this position, the annular element which engages with the annular groove presses on the support surface and thus ensures fixation.
  • the rounded surface increases the contact area with the annular element and thus increases the force exerted on the receiving element.
  • the partially circular receiving surface and the rounded supporting surface can preferably form partial sections of a circle and, in the installed state, have a common center of the circle. If the receiving surface and the support surface form partial sections of a common circle, a particularly secure fixation of the two elements to one another is ensured, since the annular element is held in the circular section formed by the two surfaces.
  • a still further preferred embodiment can provide that the receiving element is formed with a transition section which, when installed, is arranged opposite an edge formed between the contact surface and the outer lateral surface of the glass body. Since the manufacture of the vitreous body, in particular, has considerable tolerances, the provision of the transition section facilitates the introduction of the vitreous body into the receiving opening and the abutment of the accommodating element on the vitreous body, since this ensures that the accommodating element actually sits on the bearing surface of the vitreous body.
  • a diameter measured on the inner surface forming the annular gap and / or the support surface of the receiving element can be larger than a diameter measured in the region of the receiving surface of the glass body.
  • the diameter of the annular permanently elastic element corresponds at most to the diameter of the annular groove forming the receiving surface, but is preferably smaller. If the diameter of the annular, permanently elastic element is somewhat smaller than the diameter of the annular groove, this is kept under tension even in the installed state in the annular groove and thus improves the fixation of the two elements to one another.
  • the present invention further provides a method for connecting a receiving element of a lamp, the receiving element having a receiving opening for a rotationally symmetrical glass body, and a rotationally symmetrical glass body to be arranged in this receiving opening, an annular gap being formed between the receiving element and the glass body Region of the receiving element ends in a support surface inclined towards the glass body and in the region of the glass body in a receiving surface, which are arranged diametrically opposite, comprising the following steps: inserting the glass body into the receiving opening of the receiving element, stretching a permanently elastic annular element to a diameter of at least corresponds to the surface of the glass body forming a surface of the annular gap, inserting the permanently elastic ring-shaped element into the annular gap, the permanently elastic annular element is placed on the glass body, and inserting the permanently elastic annular element into the annular gap until it penetrates into the receiving surface.
  • the method according to the invention is characterized by a few effective steps that can be carried out quickly and easily. This ensures a secure fixation of the two elements to one another and also enables rattle-free assembly.
  • the permanently elastic element used can compensate for the tolerances that occur during the manufacture of the glass body, so that no additional measures are necessary here.
  • the glass body and the receiving element are preferably designed as described above.
  • the glass body is inserted into the receiving opening until the receiving element rests on a contact surface formed in the area of the lateral surface.
  • the receiving element is consequently held on the glass body on the one hand in the area of the support surface and on the other hand by the permanently elastic element arranged opposite. This ensures that the receiving element is fixed on both sides.
  • Figure 1 shows an embodiment of a lamp according to the invention, of which lamp only one receiving element 1, a rotationally symmetrical glass body 2 inserted into this receiving element, and an annular permanently elastic element 3 arranged between receiving element 1 and glass body 2 are shown. Lights and other elements of the lamp are not shown.
  • the present invention is particularly concerned with connecting these two elements to one another in a manner which represents a secure, permanent connection and at the same time leads to a connection which ensures rattle-free assembly.
  • Corresponding elements can be found in most of the known luminaires, so that this addresses a known problem.
  • the receiving element 1 is a rotationally symmetrical element which is formed with a receiving opening 4.
  • the receiving element 1 is essentially ring-shaped, comprising an outer circumferential surface 5 and a radial inner surface 6, which are connected to one another via two circular ring surfaces 10, 11 arranged parallel to one another.
  • the radial inner surface 6 surrounds the receiving opening 4.
  • the radial inner surface 6 has three differently shaped sections 7, 8 and 9.
  • the section 7, which is the longest section in relation to the height of the annular receiving element 1, is conical, the thickness of the section 7 gradually increasing in the direction of the sections 8 and 9. Consequently, the circular ring surface 10 adjoining the section 7 and extending between the section 7 and the outer circumferential surface 5 is made smaller than the circular ring surface 11 arranged parallel thereto.
  • section 7 then merges into section 8, which is formed with a curve that extends away from section 7 and the outer lateral surface 5.
  • Section 7 is followed by a straight section 9, which is arranged parallel to the outer lateral surface 5.
  • Section 8 provides a support surface are available on which the ring-shaped, permanently elastic element is supported in the installed state, or acts upon it.
  • a transition section 12 is provided between the section 9 and the annular surface 11, which is designed as a recess and extends into the receiving element 1.
  • This recess 12 is in Figure 1 Shown as a curve, but can also be angular, depending on the preferred manufacturing process.
  • section 7 is longest
  • section 8 is shortest
  • section 9 has an average length
  • Glass body 2 shown is also designed as a rotationally symmetrical body with a stepped outer surface 13 'and 13 ", and an inner surface 14. Between the two outer surfaces 13' and 13" a support surface 15 is formed, which is perpendicular to the two Sheathed surfaces 13 'and 13 "extends. Furthermore, a circumferential surface 16 extending perpendicularly to the outer circumferential surface 13" and the inner circumferential surface 14 is formed. Starting from the circumferential surface 16, the inner circumferential surface 14 extends downward and opens into a light entry surface 17, which can be formed at least in sections parallel to the circumferential surface 16.
  • the surface of the glass body 2 opposite the light entry surface 17 is the light exit surface 18, which connects the two outer lateral surfaces 13 'and can be formed at least in sections with an inward curvature.
  • the inner light entry surface 17 can also be designed with a curvature.
  • the glass body 2 has a circumferential groove 19 in the region of the outer circumferential surface 13 ′′, ie the outer circumferential surface arranged closer to the inner circumferential surface 14, which is at least partially formed with a circular cross section.
  • this circumferential groove 19 is closer to the contact surface 15 than arranged on the circumferential surface 16.
  • the circumferential groove 19 is preferably designed as a circular section, the center of the circle being arranged outside the glass body 2.
  • the circumferential groove here forms the receiving surface and serves for partially receiving and positioning the annular element 3 in the installed state.
  • the glass body 2 is inserted into the receiving opening 4 of the receiving element 1, the glass body with the peripheral surface 16 being inserted into the receiving opening 4.
  • the radial inner surface 6 of the receiving element lies opposite the outer lateral surface 13 ′′ of the glass body 2.
  • the glass body 2 is completely inserted when the circular ring surface 11 of the receiving element 1 rests on the contact surface 15 of the glass body.
  • the straight inner surface section 9 of the receiving element 1 is in contact the outer lateral surface 13 ′′ of the glass body 2, or is arranged in the vicinity thereof taking into account manufacturing-related tolerances, so that a secure positioning of the receiving element 1 in relation to the glass body 2 is ensured here.
  • the dimensions of the receiving element 1 and the glass body 2 are selected such that the rounded section 8 in the area of the radial inner surface 6 is opposite the circumferential groove 19 of the glass body 2 such that the two curves represent partial sections of the same circle and have a common center of the circle or that the common axis of symmetry of their circles coincides.
  • the areas are rounded, but it is equally possible to make these areas essentially flat, the area 8 of the receiving element 1 providing a support surface and the circumferential groove 19 of the glass body 2 providing a receiving area. It is necessary that the two surfaces are diametrically opposed and that the surface 19 provides a receiving and positioning of the ring-shaped element 3, which fixes the ring-shaped element 3 in the assumed position.
  • the diameter of the glass body 2 in the circumferential groove 19, and here in particular in the groove base, is smaller than the circumferential diameter of the entire radial inner surface 6 of the receiving element.
  • annular gap 20 is formed between the receiving element 1 and the glass body 2, which finally ends in the circle formed by the circumferential groove 19 and the area 8.
  • This annular gap 20 is tapered due to the conical design of the section 7 and serves as an insertion area for the permanently elastic annular element 3.
  • this permanently elastic annular element 3 is located in the circumferential groove 19 and at the same time also in the region 8 of the receiving element 1.
  • the circumferential groove 19 consequently forms a receiving surface, whereas the region 19 serves as a supporting surface for the permanently elastic annular element 3.
  • the glass body 2 is first inserted into the receiving opening 4 of the receiving element 1 until the circumferential groove 19 and the arcuate section 7 are positioned such that they face each other and the common axis of symmetry of their circles coincide.
  • the receiving element 1 with the circular ring surface 11 simultaneously abuts the contact surface 15 of the glass body.
  • the transition section 12 in the area of the receiving element 1 serves to compensate for any inaccuracies in the area of the glass body, which may be caused by the manufacture. This can ensure that the annular surface 11 of the receiving element 1 actually rests on the bearing surface 15 and the support surface 8 and the receiving surface 19 assume the correct positions relative to one another.
  • the permanently elastic annular element 3 is inserted through the annular gap 20.
  • the annular element is first stretched to the diameter of the outer surface 13 "of the glass body 2 and put on this outer surface 13".
  • the annular element is then axially displaced along this lateral surface until the circular circumferential groove 19 is reached.
  • the ring retracts into the circumferential groove 19 and lies both in the circumferential groove 19 and in the region 9 in the form of a circular arc. In this state, both parts are now firmly connected.
  • the permanently elastic ring-shaped element fixes both parts positively and concentrically to each other. It is in radial contact with both the receiving element 2 and with the glass body 3.
  • the parts are thus fixed in the axial direction on the one hand by their stop in an axial direction, i.e. the circular ring surface 11 bears on the bearing surface 15, on the other hand the ring-shaped element in the circumferential groove 19 and on the circular region 8 blocks movement in the other axial direction.
  • the assembly is preferably carried out by a tool specially developed for insertion into the annular gap, which ensures quick and secure positioning of the annular element.
  • This tool is preferably also annular, so that a uniform force is applied to the annular element in order to insert it can be exercised.
  • the tool can be conical with a shape that is approximately adapted to the annular gap.
  • the use of the permanently elastic annular element is advantageous.
  • the installation position and the ring diameter can be coordinated so that a slight axial pull "against" the stop of the parts remains. In this way, a preload can be generated in the system, which enables “rattle-free” assembly.
  • the system can only be disassembled by destroying the permanently elastic ring-shaped element. This can be done by an enormous axial force, for example shearing off the permanently elastic ring-shaped element in the gap between the arc-shaped region 9 and the assembled part or by cutting and removing the ring-shaped element from above.
  • the pull-off force required to destroy the annular element is significantly higher than the force required to hold the assembled part.
  • a soft, elastic O-ring for example a ring made of an elastomer, such as silicone or EPDM, can be used here, for example, as the permanently elastic ring-shaped element.
  • the method according to the invention enables a very simple assembly of two components, as a result of which more complex methods, for example gluing, can be avoided.
  • this method has proven itself for components in which tolerances caused by the production can occur.
