Abstract

A light weight carrier movable along vertical guide posts of a wood planer includes left and right mounting seats having front and rear support blocks projecting oppositely and inwardly therefrom, front and rear guide holes adapted for extension of the guide posts, and cutter mounting holes each disposed between front and rear support blocks and between the front and rear guide holes, front and rear connecting rods each having left and right end sections respectively connected to the left and right mounting seats at the front and rear support blocks; a motor mounting plate fixed between the front support blocks; and a rear cover plate fixed between the rear support blocks.

Claims

1. A carrier for a wood planer to carry a motor and a cutter and to move upward and downward along vertical guide posts, said carrier comprising:

left and right mounting seats each having front and rear support blocks, front and rear guide holes, and a cutter mounting hole adapted for mounting the cutter and disposed between said front and rear support blocks and between said front and rear guide holes, said front and rear support blocks projecting oppositely and inwardly from said left and right mounting seats, said front and rear guide holes being adapted for extension of the guide posts,

a front connecting rod having left and right end sections respectively connected to said front support blocks of said left and right mounting seats;

a rear connecting rod having left and right end sections respectively connected to said rear support blocks of said left and right mounting seats;

a motor mounting plate disposed above said front connecting rod and having left and right ends respectively fixed to said front support blocks of said left and right mounting seats; and

a top connecting rod having left and right end sections, said left and right mounting seats further having top ends which are provided with second insert holes, respectively, said left and right end sections of said top connecting rod being inserted into said second insert holes, respectively.

2. The carrier of claim 1, wherein each of said left and right mounting seats includes a base portion having a front end and a back end, a top portion having a front end and a back end, a front portion projecting between, and connected to, the front end of each of said base and top portions, and a rear portion projecting between, and connected to, the back end of each of said base and top portions, said front and rear portions each having, respectively, said front and rear support blocks projecting therefrom.

3. The carrier of claim 2, wherein said front and rear portions of said left and right mounting seats are provided with front and rear guide sleeves defining said front and rear guide holes.

4. The carrier of claim 2, wherein each of said left and right mounting seats further has two first insert holes one of which extends through said front support block and said front portion and the other one of which extends through said rear support block and said rear portion, each of said left and right end sections of each of said front and rear connecting rods being stepped and having an end neck, a shoulder adjacent to said end neck, a longitudinal screw hole extending longitudinally and opening at an end of said end neck, and a fastening screw, said end neck being inserted into one of said first insert holes of said left and right mounting seats, said fastening screw extending into said longitudinal screw hole to fasten a respective one of said left and right end sections to one of said front and rear portions.

5. The carrier of claim 4, wherein each of said left and right end sections of each of said front and rear connecting rods further has a transverse screw hole communicated with said longitudinal screw hole, and an abutment screw extending transversely through said transverse screw hole to abut against said fastening screw.

6. The carrier of claim 5, wherein each of said front and rear connecting rods further has an intermediate section with a rounded periphery between said left and right end sections, and two transversely opposite recessed flat faces formed in said rounded periphery.

7. The carrier of claim 1, wherein said motor mounting plate has a top plate portion extending above said front connecting rod, a front plate portion extending downwardly from said top plate portion in front of said front connecting rod, and screw fasteners to fasten said top and front plate portions to said front support blocks of said left and right mounting seats.

8. The carrier of claim 1, wherein said left and right end sections of said top connecting rod are stepped and each have an end neck inserted into one of said second insert holes.

9. A carrier for a wood planer to carry a motor and a cutter and to move upward and downward along vertical guide posts, said carrier comprising:

left and right mounting seats each having front and rear support blocks, front and rear guide holes, and a cutter mounting hole adapted for mounting the cutter and disposed between said front and rear support blocks and between said front and rear guide holes, said front and rear support blocks projecting oppositely and inwardly from said left and right mounting seats, said front and rear guide holes being adapted for extension of the guide posts,

a front connecting rod having left and right end sections respectively connected to said front support blocks of said left and right mounting seats;

a rear connecting rod having left and right end sections respectively connected to said rear support blocks of said left and right mounting seats;

a motor mounting plate disposed above said front connecting rod and having left and right ends respectively fixed to said front support blocks of said left and right mounting seats; and

a rear cover plate extending between said left and right mounting seats and fixed to said rear support blocks of said left and right mounting seats;

wherein said rear cover plate includes a top plate portion disposed above said rear connecting rod, a fence plate portion extending downwardly from said top plate portion in front of said rear connecting rod, and a back plate portion extending downwardly from said top plate portion behind said rear connecting rod.

10. the carrier of claim 9, wherein said read cover plate further includes first tabs projecting respectively and rearwardly from two ends of said fence plate portion, second tabs projecting respectively and downwardly from two ends of said top plate portion, third tabs projecting respectively from two ends of said back plate portion, and screw fasteners to fasten said first, second and third tabs to said rear support blocks.
