Abstract

A laser indicator includes a weight mechanism having a bracket with a weight secured to the bracket in a manner where the weight is suspended by gravity. A plurality of laser generators are arranged about the weight, including a horizontal beam generator, a center laser generator arranged at the axial center of the bottom of the weight for emitting a laser point coaxial to the axial line of the weight, and a plurality of vertical beam generators positioned in spaced-apart manner around the axial center of the weight at the top of the weight. The laser indicator can include a stand that includes a seat having a plurality of legs, and a rotary table having a plurality of legs, with the weight mechanism coupled to the rotary table, and the rotary table removably coupled to the seat so that altitude of the weight mechanism can be adjusted. In addition, the laser indicator can include a securing mechanism is for coupling the weight to the upper bracket of the bracket.

Claims

1. A multidirectional laser indicator, comprising:

a weight mechanism having a bracket with a weight secured to the bracket in a manner where the weight is suspended by gravity, the weight having a bottom with an axial line;

a plurality of laser generators arranged about the weight, including;

a. a horizontal beam generator;

b. a center laser generator arranged at the axial center of the bottom of the weight for emitting a laser point coaxial to the axial line of the weight; and

c. a plurality of vertical beam generators positioned in spaced-apart manner around the axial center of the weight at the top of the weight;

wherein each of the horizontal beam generator and vertical beam generators has a supporting seat and a laser module positioned inside the supporting seat to project a laser beam parallel to the axial line of the weight, each laser module having a front portion, a lens, a pivot axis whose axial center extends toward the center of the lens of the respective laser module, and a plurality of adjusting bolts that extend through the respective supporting seat to contact against the respective laser module.

2. The laser indicator of claim 1, wherein the front portion of each laser module is positioned using the pivot axis such that, when the adjusting bolts of the particular laser module are rotated, the laser module will rotate about the pivot axis so as to adjust a projecting angle of the laser beam being emitted.

3. The laser indicator of claim 1, wherein the pivot axis is a pivot bolt that extends through the supporting seat, the pivot bolt having an end that contacts the laser module so that when the adjusting bolts of the laser module are rotated, the laser module will rotate using the contact point of the pivot bolt and the laser module as an axis.

4. The laser indicator of claim 1, wherein:

the pivot axis of each vertical beam generator is provided at the bottom of the respective laser module, and an adjusting bolt is arranged at two sides of the laser module; and

the pivot axis of the horizontal beam generator is provided at one side of the laser module, and an adjusting bolt is provided at a side that is opposite the one side of the respective laser module away from the pivot axis.

5. The laser indicator of claim 1, further including a stand that includes:

a seat having a plurality of legs; and

a rotary table having a plurality of legs, with the weight mechanism coupled to the rotary table, and the rotary table removably coupled to the seat so that the altitude of the weight mechanism can be adjusted.

6. The laser indicator of claim 1, wherein the bracket has an upper bracket, the laser indicator further including a securing mechanism for coupling the weight to the upper bracket, the securing mechanism including:

a bearing set provided in the upper bracket and having an inner ring, an outer ring and a bearing retained between the inner ring and the outer ring;

a movable axial center extending through the weight and the upper bracket, and having one end that abuts against the inner ring;

a fixing bolt that fixes the movable axial center securely in the weight; and

a fixing ring that is abutted against the exterior of the outer ring.

7. The laser indicator of claim 1, wherein the laser beams emitted by the vertical beam generators intersect each other at the axial line at the top of the weight mechanism.

8. A multidirectional laser indicator, comprising:

a weight mechanism having a bracket with a weight secured to the bracket in a manner where the weight is suspended by gravity, the weight having a bottom with an axial line;

a plurality of laser generators arranged about the weight; and

a stand that includes;

a. a seat having a plurality of legs; and

b. a rotary table having a plurality of legs, with the weight mechanism coupled to the rotary table, and the rotary table removably coupled to the seat so that the altitude of the weight mechanism can be adjusted.

9. The laser indicator of claim 8, wherein the plurality of laser generators includes:

a horizontal beam generator;

a center laser generator arranged at the axial center of the bottom of the weight for emitting a laser point coaxial to the axial line of the weight; and

a plurality of vertical beam generators positioned in spaced-apart manner around the axial center of the weight at the top of the weight.

10. The laser indicator of claim 8, wherein the legs of the rotary table are provided at the bottom of the rotary table, and are shorter than the legs of the seat.

11. The laser indicator of claim 8, wherein the rotary table further includes:

a rotary plate positioned inside the rotary table;

a transmission gear engaging the rotary plate; and

a knob engaging the transmission gear;

wherein the weight mechanism is coupled to the rotary plate such that when the knob is rotated, the transmission gear will drive the rotary plate to adjust the projecting direction of the plurality of laser generators.

12. A multidirectional laser indicator, comprising:

(i) a weight mechanism having a bottom with an axial line, and including;

a. a bracket having an upper bracket;

b. a weight; and

c. a securing mechanism for coupling the weight to the upper bracket, the securing mechanism including;

c1. a bearing set provided in the upper bracket and having an inner ring, an outer ring and a bearing retained between the inner ring and the outer ring;

c2. a movable axial center extending through the weight and the upper bracket, and having one end that abuts against the inner ring;

c3. a fixing bolt that fixes the movable axial center securely in the weight; and

c4. a fixing ring that is abutted against the exterior of the outer ring; and

(ii) a plurality of laser generators arranged about the weight.

13. The laser indicator of claim 12, wherein the plurality of laser generators includes:
