    (54) Movable reading lamp


    (57) The lamp has an opaline translucent body (1) with a circular cross-section tapering from its base upwards by following a curved profile to a determined height where it then becomes cylindrical in shape so as to create the visual perception of a candle, from the viewpoint of both the body shape and the opalescent effect of the material used. Inside the body (1), a light bulb (2) is placed immediately under the mouth (3). The opaline body (1) is engaged onto a base (4) made of opaque material, the latter creating the visual perception of the support plate of a traditional candlestick.




    Description


    [0001] The invention refers to a movable reading lamp to be easily transported inside the house from a room to another one which is principally characterized by the fact to permit visual perception referring to a low candlestick with candle and also to can be used as substantial alternative to said candlestick. The candlestick, meant like metal stem to support one or more candles, in spite of its inborn inconveniences coming from the burning wax creating smoke and from a flame which disturbs the sight and which can lie dangerous for the fittings is current used both for the high decorative effect which permits than for the emotional sensations which suggests. These characteristics made of this object irreplaceable fittings in the sector of the knick-knacks and also to be used for example to lay tables. Between the candlesticks, the low stem candlestick with support plate is currently the sole knick-knack to be used to light up during the moving from a room to another one. The requirements satisfied by the above cited low stem candlestick with support plate can in no case to be satisfied by the current lamps since the reading lamps are suited to be put in standing and moreover they take electric energy from the electric grid by means of wires and the movable lamps can be used only to light up and not like knick-knack. Starting from these considerations the invented lamp realizes a new lamp for interior decoration creating a visual perception of a candlestick with support plate and with a candle and suited to be standing onto a plane and to be moved. For these characteristics the invented lamp can be proposed like alternative to the use of the traditional candlestick with support plate. In comparison with the traditional candlestick with support plate the invented lamp permits a lot of advantages since, realizing a one-piece lamp to be grasped, it makes more safe its use both during standing on plane than during its moving. This characteristic becomes the new lamp particularly to be used into public places since it avoids the presence of combustion parts, the pollution and the fire risks. Moreover excluding the presence of direct light source it avoids to offend the sight, distinctiveness of big importance in the case of use of the invented lamp to lay the tables. In the end the invented lamp, realizing a raising body with visual perception of candle, acts like light diffuser with differentiated effect so to create a new kind of lighting with gradual intensity from the bottom upwards starting from a part in shade so to create a particular suggestiveness. The ornamental invented lamp foresees a opaline translucent body 1 with circular section in tapering from its base upwards with curved profile to a determined height to then become a cilindric shape so to determine a new lamp-shade with visual perception of a candle, perception given both from the body shape than to the opalescent effect of the material used. Inside this body 1 is foreseen a light source with bulb 2 placed immediately under the ventilation mouth 3. The opaline body 1 is engaged into a base 4 in opaque material so to create visual perception of the support plate of the traditional candlestick. To light up the invented lamp is foreseen a light point with a bulb 2 to be mounted on a bulb-holder 5 supported onto a stem 6 with electric feed given by piles 7 housing into the seat 8. The lighting is driven by current switches. In a preferred embodiment is foreseen a coaxial joint in which the plastic body 1 is inserted into the plastic base 4 with bounded rotation. This particular joint permits to use one of the parts (the body 1 or the base 4) like switch moving the same while the other part is held in position. This joint, which is based on the elasticity of the plastic material, foresees the pressure introduction of the anularpart 9 of the base 4 into the fitting up part 10 of the body 1 with stop onto the crown 11. The permanent contraint is permitted by the initial opening out of the appendix 12 of the body 1 which gets into the rotation circular seat 13 of the base 4 and places itself into the same seat 13. In this way the body 1 and the base 4 are bound in rotation on the base of prearranged run-limits 14 foreseen on the base 4. This permits to each of the parts of the lamp (body 1 or base 4) to be used like switch. Inside the body lamp are used current means for the electric current with electric wires to connect the piles 7 and the bulb 2 through the stem 6. For using the base 4 like switch is foreseen on its bottom a taking part 15. As example of the present invention is illustrated in sheets 1 and 2 a lamp with plastic body 1 and with plastic base 4 with a light point given by a bulb 2 to be fed with piles 7. In sheet 1 fig. 1 is longitudinal section view of the invented lamp suited to be used. Fig. 2 is side view of the lamp. Fig. 3 is bottom view. Fig. 4 is top view. In sheet 2 fig. 5 is longitudinal section view of a detail of fig. 1 with the body 1 and the base 4 disengaged. Fig. 6 is perspective view of the lamp. Fig. 7 is view of the same lamp of fig. 6 but with the lamp grasping for its moving.The materials, the shapes and the colours of the body 1 and of the base 4 can be foreseen on the base of the different necessities. The light source can use the different types of lighting like gas illumination, oil illumination or other ones. In particular is foreseen on the bottom of the lamp a light source to light up an optical fibre placed into the duct 16 and ending with the ventilation mouth 3.


    Claims

    1. Movable reading lamp foreseen a opaline translucent body (1) engaged into a base (4) in opaque material with a light source foreseen a bulb (2) placed immediately under the ventilation mouth (4), characterized in that the opaline body (1) with circular section in tampering from its base upwards with curved profile to a determined height to then become a cilindric shape determines a new lamp-shade with visual perception of a candle, perception give both from the body shape than to the opalescent effect of the material used; and the base (4) creates a visual perception of the support plate of the traditional candlestick.
     
    2. Movable reading lamp, as for claim 1), in that for the lighting is foreseen a light point with a bulb (2) to be mounted on a bulb-holder (5) supported onto a stem (6) with electric feed given by piles (7) housing into the seat (8); the lighting is then driven by current switches.
     
    3. Movable reading lamp, as for claim 1), in that an embodiment foresees a coaxial joint in which the plastic body (1) is inserted into the plastic base (4) with bounded rotation; this particular joint permits to use one of the parts: the body (1) or the base (4) like switch moving the same while the other part is held in position; this joint, which is based on the elasticity of the plastic material, foresees the pressure introduction of the anular part (9) of the base (4) into the fitting up part (10) of the body (1) with stop onto the crown (11); the permanent constraint is permitted by the initial opening out of the appendix (12) of the body (1) which gets into the rotation circular seat (13) of the base (4) and places itself into the same seat (13); in this way the body (1) and the base (4) are bound in rotation on the base of pre-arranged run-limits (14) foreseen on the base (4); this permits to each of the parts of the lamp to be used like switch; inside the body lamp are used current means for the electric current with electric wires to connect the piles (7) and the bulb (2) through the stem (6).
