| (54) | Light projector preferably for outdoor environments with a fastening device for a tilting lid in an open position. |
| (57) A light projector preferably for outdoor environments is described consisting of
a lower body (2) supporting a lamp and a transparent lens (4), superiorly closed by
a tilting lid (3). Said projector comprises a device (5) integrated in the lower body
(2) for fastening said tilting lid (3) in an open position.

[0001] The present invention relates to a light projector preferably for outdoor environments with a fastening device for a tilting lid in an open position.
[0002] Light projectors consisting of a lower body supporting a lamp and a transparent lens, superiorly closed by a tilting lid hinged to said lower body are known.
[0003] This type of projector is particularly suitable for outdoor environments, in particular for road lighting.
[0004] Once assembled, the projector is secured to a supporting pole, often at considerable heights, and maintenance operations are consequently not easy.
[0005] In order to access the wiring or the lamp, the upper lid which is rather heavy in virtue of the considerable dimensions of the projector, must be tilted.
[0006] The hinge with which said lid is connected to the lower body usually does not allow excessive rotations, which are slightly higher than 90°.
[0007] The working place itself of the projector often does not allow rotations much higher than 90° (for example in large industrial sheds or along tree lined roads).
[0008] A rotation slightly higher than 90° means an open position of the lid slightly diverging from the vertical. This entails the risk of the lid suddenly closing, a situation which is certainly to be avoided for the maintenance personnel working, for example, on the top of a pole at ten metres from the ground by the edge of the road. As mentioned, said lids are generally very heavy.
[0009] To prevent risks, maintenance personnel often use a hand to prevent the lid from closing. This entails a reduced dexterity and a consequent considerable waste of time.
[0010] It is the object of the present invention to achieve a light projector of the type described above with a device capable of safely fastening the lid in an open position.
[0011] According to the invention, this object is reached by means of a light projector preferably for external environments consisting of a lower body supporting a lamp and a transparent lens, superiorly closed by a tilting lid, characterised in that it comprises a device integrated in the lower body for fastening said tilting lid in an open position.
[0012] Said device allows the maintenance personnel to work in absolute safety, using both hands to repair the projector. The lid can be returned to closed position only by the deliberate action of the maintenance personnel on the device.
[0013] These and other features of the present invention will become further apparent from the following detailed description of a practical embodiment thereof shown by way of non-limitative example in the attached drawings, in which:
figure 1 shows a longitudinal section side view of a projector with closed lid;
figure 2 shows a longitudinal section side view of the projector in figure 1 with open lid;
figure 3 shows a top plan view of the projector in figure 1 without lid;
figure 4 shows a top plan view of the projector in figure 2 without lid;
figure 5 shows a magnified detail of figure 3;
figure 6 shows a magnified detail of figure 4.
[0014] A light projector 1 consists of a lower body 2 superiorly closed by a tilting lid 3 hinged to said lower body 2 which presents a rear part 15 for fastening to external supporting means (not shown).
[0015] The lower body 2 supports a lamp (not shown), a transparent lens 4 and a device 5 for fastening the lid 3 in an open position.
[0017] The fastening member 6 consists of a perforated base 8 rotationally fixed to the lower body 2 by means of a pin 10 and by an elongated portion 9 integral with said perforated base 8.
[0018] The perforated base 8 comprises an eyelet 11 to which an end of the spring 7 is connected, the other end being hinged to the lower body 2.
[0021] When the lid is closed (fig. 1) the fastening member 6 is found in home position in figures 3 and 5 with the spring 7 which partially clasps the pin 10 pulled. The traction force of the spring which induces the rotation of the fastening member 6 is contrasted by the contact between the end of the elongated portion and the lid 3.
[0022] When the lid 3 is opened, the latter contact comes less and the fastening member 6 is forced by the spring 7 to turn until the end of the elongated portion 9 touches the stop pin 12.
1. A light projector preferably for outdoor environments consisting of a lower body (2)
supporting a lamp and a transparent lens (4), superiorly closed by a tilting lid (3),
characterised in that it comprises a device (5) integrated in the lower body (2) for fastening said tilting
lid (3) in an open position.
2. A projector according to claim 1, characterised in that said device (5) comprises a fastening member (6) urged in a locked position by a
spring (7) and normally held in home position by said tilting lid (3) when the latter
is in a closed position.
3. A projector according to claim 2, characterised in that said fastening member (6) consists of a perforated base (8) rotationally fixed to
the lower body (2) and an elongated portion (9), integral with said perforated base
(8), whose end interferes with the lid (3).
4. A projector according to claim 1, characterised in that said tilting lid (3) is hinged to the lower body (3).
5. A projector according to claim 1, characterised in that said lower body (2) comprises a rear part (15) for fastening external supporting
means.
