Abstract

The invention relates to a lamp fitting intended for attachment to a tube, rod or other elongate member, for example the bar of a sunshade, the lamp fitting comprising a ring which bears at least one lamp and which is to be arranged round the elongate member and attached thereto by means of attachment means, the ring having an inner surface extending over some axial distance and co-operating with the elongate member, which inner surface has a shape adpated to the cross-sectional form of this elongate member. The invention has for its object to give a lamp fitting a form such that it can be attached from the side in any required position to a tube, bar or rod, without it being necessary to slide it on from a free end part. This purpose is realized according to the invention by a lamp fitting of the type referred to in the preamble which displays the feature that the attachment ring is formed so as to be divisible along its circumference and so that the constituent ring parts can be connected by coupling means such that a first ring part with its inner face can be set to co-operate in radial direction with the elongate member, following which the or each complementary ring part with its inner face can be set to co-operate with the elongate member and the constituent ring parts can be assembled into the ring by means of the coupling means.

Claims

1. A lamp fitting assembly comprising the combination of collar means having an axial opening therethrough for receiving a support pole in surrounding relation thereto, a plurality of tubes extending radially from the collar means, a lamp fixed to each tube in radially outwardly spaced relation to the collar means, the collar means including separate parts which are movable relative to each other between a first position defining a radial gap permitting the collar means to be moved radially to accept the pole at any position along its length and a second position enclosing the entire circumference of the pole in circumferentially embracing relation thereto, coupling means for holding the parts in the second position enclosing and circumferentially embracing the pole, one of the parts being C-shaped to define, by itself, the gap which accepts the pole, and a second part being of truncated pie-shape to fit snugly within the gap, the C-shaped one part comprising upper and lower C-shaped end walls and concentric inner and outer part-tubular upright walls, the lower end wall being removable to gain access to the interior of the one part, and electrical wire lead-in means in the lower end wall.

2. A lamp fitting assembly comprising the combination of collar means having an axial opening therethrough for receiving a support pole in surrounding relation thereto, a plurality of tubes extending radially from the collar means, a lamp fixed to each tube in radially outwardly spaced relation to the collar means, the collar means including separate parts which are movable relative to each other between a first position defining a radial gap permitting the collar means to be moved radially to accept the pole at any position along its length and a second position enclosing the entire circumference of the pole in circumferentially embracing relation thereto, and coupling means for holding the parts in the second position enclosing and circumferentially embracing the pole, one of the separate parts being C-shaped comprising upper and lower C-shaped end walls and concentric inner and outer part-tubular upright walls defining a hollow interior communicating with the interiors of the tubes to route electrical wire to the lamps, the lower end wall being removable to gain access to the interior of the one part, and electrical wire lead-in means for routing electrical wire to the interior of the one part.

3. A lamp fitting assembly comprising the combination of collar means having an axial opening therethrough for receiving a support pole in surrounding relation thereto, at least one tube extending radially from the collar means, a lamp fixed to the tube in radially outwardly spaced relation to the collar means, the collar means including separate parts which are movable relative to each other between a first position defining a radial gap permitting the collar means to be moved radially to accept the pole at any position along its length and a second position enclosing the entire circumference of the pole in circumferentially embracing relation thereto, and coupling means for holding the parts in the second position enclosing and circumferentially embracing the pole, one of the parts being of pie-shaped configuration having converging opposite sides and the other part having converging sides defining a pie-shaped recess for receiving the one part, the coupling means comprising keying elements between the opposite sides of one part and the opposite sides of the other part, the keying elements extending at an angle longitudinally with respect to the axis of the support pole to force the parts radially inwardly in response to relative longitudinal movement therebetween.

4. A lamp assembly as defined in claim 3 wherein the parts are provided with cooperative flange and notch structure which limits the longitudinal movement therebetween.

5. A lamp assembly as defined in claim 4 including elastic members cooperating with the parts to grip the pole when the parts are forced radially inwardly.

6. A lamp assembly as defined in claim 3 wherein each part is formed with inner and outer concentric tubular portions defining chambers therebetween and end walls at the ends of the tubular portions, one of the outer tubular portions having an opening therein for receiving electrical conductors and one of the wall members being removable to gain access to the electrical conductors within the chambers internally of the parts.
