Luminaire device with dual function of table lamp and light container.

The present invention relates to a dual function lighting device respectively table lamp on the one hand and luminous container that can serve as carafe or vase on the other.

Various types of nomadic lamps of different shapes are known, as well as different carafes or vases that function as a fixture, such as in FR 30039293. Although some models of table lamps can be arranged in one direction or the other, no model can turns into a liquid or solid container when spilled. Likewise for the known luminous carafes, none are designed to be stable and offer the possibility of becoming a table lamp by reversing.

The principle of the present invention aims to provide a dual function lighting device respectively table lamp on the one hand and a light container that can serve as carafe or vase on the other hand depending on the position of a first part and a second part of the device, by reversing one relative to the other. The principle of the invention lies in the fact that it is possible with a single object to obtain either a luminaire or a light container by manually changing the positioning of the product to change the destination or main function.

The first part 1 forms the foot of the lamp A (Figure 1A or 2A) or the neck of the carafe B (Figure 1B or 2B).

Example 1

In FIGS. 1A-1B, in its central running portion 1 ', the first lateral wall 1a has a cylindrical shape with a circular cross section of diameter D1 which is prolonged with: a first part lal flared curved in vertical section which forms the pouring pan of the carafe, gradually increasing in diameter towards its open end lb of diameter D3 of approximately 2 to 2.5 times Dl, and

a second flared portion 2 flared in vertical section gradually increasing in diameter from D1 to D4 until reaching a first end 1-2 of the second side wall 2a of diameter D4 less than or equal to D3.

The first side wall has a first open end Ib with a circular contour delimiting an orifice closed by a first cover 1c with an outer surface of planar shape thus defining a said first base 1d being able to stably support the device when it serves A lamp placed on a horizontal plane.

The contour in vertical section of the second side wall 2a when one of the first base or second base of the device rests in position on a horizontal plane, is concavely curved towards the internal cavity that it defines. The second revolution side wall 2a extends from its first open end 1-2 communicating with the first side wall la to a second end 2b in the direction ZZ '. The second side wall 2a in an intermediate portion between its ends 1-2 and 2b of larger diameter having a widest diameter D2 equal to about 2 times D3 for example D2 being about 20 to 25cm.

The first part 1 extends over a height H1 substantially equal to the height H2 of the second part 2, for example H1 and H2 being about 10 to 15 cm.

The second end 2b is closed by a wall of revolution 3a according to ZZ ', forming a hollow wall internal to the internal cavity of the second lateral wall 2 forming a watertight compartment 3a with respect to the liquid contained in the internal cavity of the second side wall. The wall of revolution 3a has an ellipsoidal contour in axial section (XZ or YZ) with a concavity turned towards the second end 2b. The second end 2b of the second side wall 2a delimits a circular orifice of diameter substantially equal to D3 adapted to cooperate with a removable cover 2c closing the sealed compartment 3a containing a removable lighting module 3. The second end 2b borders an inner circular groove 3a 1 of the wall 3a which receives the cover 2c so that the cover 2c has a flat outer face at the level of said second end forming a second base 2d able to support stably the device when it serves carafe B placed on a horizontal plane.

The diameter D3 of the first end 1b and the second end 2b is thus wide enough to delimit a first base capable of stably supporting the device when it serves as a lamp placed on a horizontal plane and a second base capable of stably supporting the device when serving as a carafe placed on a horizontal plane.

The covers 1c and 2c are screwed onto annular parts Here and 2c1 with screw threads integral with the orifices formed at the first end 1b and respectively the second end 2b.

The second cover 2c provides access to the lighting module 3 to replace and / or recharge.

Preferably, the first lid is sufficiently sealed to allow the luminaire to be used in a table lamp position filled with liquid.

Example 2

In FIGS. 2A-2B, the first lateral wall 1a and its end have a vertical plane of symmetry XZ and YZ with a rectangular section, and the base 1d as well as said second lateral wall 2a and its second base 2d have a vertical plane of symmetry XZ and YZ with square section.

In FIGS. 2A-2B, the first end 1b and the first side wall 1a are of rectangular section of less area than the circular surface of the device of FIGS. 1A and 1B. But, the first end lb cooperates with a base ld including a lid. The base ld square is of dimension D3 side large enough to form a first base capable of stably supporting the device when it serves as a lamp placed on a horizontal plane.

According to this embodiment, the current portion of the second side wall 2a has a truncated pyramid shape. The junction 2a2 between the first side wall la and the second side wall 2a has a discontinuous dimensional variation of the dimension in a direction parallel to the XY plane of said first and second bases. This junction 2a2 is flat and square D2 side corresponding to the large base of the pyramid, so the larger area of the second side wall, and forms the second base. This junction 2a2 extends between the first side wall la and the first rectangular end 1-2 of the second side wall 2a. Similarly, the second end 2b of the second side wall 2a delimits a second base 2d that is approximately 1.5xD3 wider than the circular central orifice 2b 'cooperating with the second cover 2k.
