Abstract

An umbrella includes a hollow shank that is open at an upper end. A hollow lamp holder unit is provided on the upper end of the shank and has a closed upper end to which a plurality of ribs are connected, an open lower end formed with a central hole to permit the shank to extend into the lamp holder unit, and a positioning rod which extends from the upper end and into the shank. The positioning rod has a longitudinal groove formed on a periphery thereof. A slidable ring is sleeved on the shank. A plurality of spreaders are connected pivotally to a periphery of the ring member at one end and are connected pivotally and respectively to the ribs at the other end. A lighting element is mounted securely on the lower end of the lamp holder unit adjacent to the central hole. An electric cable unit is disposed inside the shank and extends through the groove in the positioning rod and into the lamp holder unit, thereby interconnecting the lighting element electrically with a power source. A support member is secured on the shank between the lamp holder unit and the ring member and is spaced apart from the lamp holder unit. A transparent tubular cover is retained removably between the lamp holder unit and the support member to permit removal of the lighting element when the cover is removed.

Claims

1. An umbrella with a lighting device, said umbrella including a shank with an upper end, a plurality of ribs connected pivotably to said upper end of said shank at one end thereof, a slidable ring sleeved on said shank, and a plurality of spreaders which are connected pivotally to a periphery of said ring member at one end and which are connected pivotally and respectively to said ribs at the other end, wherein the improvement comprises:

said shank being hollow and being open at said upper end;

a hollow lamp holder unit which is provided on said upper end of said shank and which has a closed upper end, an open lower end which is formed with a central hole to permit said shank to extend into said lamp holder unit, and a positioning rod which extends from said upper end and into said shank, said positioning rod having a longitudinal groove formed on a periphery thereof, said upper end of said lamp holder unit interconnecting pivotally said shank and said one end of each of said ribs;

a lighting element mounted securely on said lower end of said lamp holder unit adjacent to said central hole;

an electric cable unit disposed inside said shank, said cable unit having a lower end to be connected to a power source and an upper end which extends into said groove of said positioning rod and into said lamp holder unit and which is connected electrically to said lighting element;

a support member which is secured on said shank between said lamp holder unit and said ring member and which is spaced apart from said lamp holder unit; and

a transparent tubular cover retained removably between said lamp holder unit and said support member to permit removal of said lighting element when said tubular cover is removed.

2. An umbrella with a lighting device as claimed in claim 1, wherein each of said lamp holder unit and said support member has a plurality of claw elements provided on a periphery thereof to retain said transparent tubular cover therebetween, at least one of said claw elements on said lamp holder unit and said support member being removable therefrom so that said tubular cover can be removed when said at least one of said claw elements is removed.

3. An umbrella with a lighting device as claimed in claim 2, wherein said transparent tubular cover includes two longitudinal halves and two coupling elements which interconnect removably said longitudinal halves so that one of said longitudinal halves can be removed when said at least one of said claw units is removed.

4. An umbrella with a lighting device as claimed in claim 1, wherein said lower end of said lamp holder unit has a reflective bottom surface.

5. A garden umbrella to be installed on a garden table and provided with a lighting device, said garden umbrella including a shank with an upper end, a plurality of ribs connected pivotably to said upper end of said shank at one end thereof, a slidable ring sleeved on said shank, and a plurality of spreaders which are connected pivotally to a periphery of said ring member at one end and which are connected pivotally and respectively to said ribs at the other end, wherein the improvement comprises:

said shank being hollow and being open at said upper end, said shank being adapted to be positioned on said garden table, said shank further having a lower end;

a hollow lamp holder unit which is provided on said upper end of said shank and which has a closed upper end, an open lower end which is formed with a central hole to permit said shank to extend into said lamp holder unit, and a positioning rod which extends from said upper end and into said shank, said positioning rod having a longitudinal groove formed on a periphery thereof, said upper end of said lamp holder unit interconnecting pivotally said shank and said one end of each of said ribs;

a lighting element mounted securely on said lower end of said lamp holder unit adjacent to said central hole;

an electric cable unit disposed inside said shank, said cable unit having a lower end which extends out of said lower end of said shank and which is provided with a plug so as to connect with an electric outlet, and an upper end which extends into said groove of said positioning rod and into said lamp holder unit and which is connected electrically to said lighting element;

a support member which is secured on said shank between said lamp holder unit and said ring member and which is spaced apart from said lamp holder unit; and

a transparent tubular cover retained removably between said lamp holder unit and said support member to permit removal of said lighting element when said tubular cover is removed.

6. A garden umbrella as claimed in claim 5, wherein each of said lamp holder unit and said support member has a plurality of claw elements provided on a periphery thereof to retain said transparent tubular cover therebetween, at least one of said claw elements on said lamp holder unit and said support member being removable therefrom so that said tubular cover can be removed when said at least one of said claw elements is removed.

7. A garden umbrella as claimed in claim 6, wherein said transparent tubular cover includes two longitudinal halves and two coupling elements which interconnect removably said longitudinal halves so that one of said longitudinal halves can be removed when said at least one of said claw units is removed.

8. A garden umbrella as claimed in claim 5, wherein said lower end of said lamp holder unit has a reflective bottom surface.
