Abstract

In one embodiment, a crosspiece forming a spider for a laundry appliance, may include a plurality of support arms extending from a center, the support arms configured to be attached to a drum of the laundry appliance, wherein the center is configured to receive a shaft of a drive mechanism of the laundry appliance and translation rotational motion to the drum during use; and where the support arms are formed from a first part and a second part, where the first part is coupled to the second part to form a hollow interior and increase inertia momentum of the spider during use.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A crosspiece forming a spider for a laundry appliance, comprising:
 a plurality of support arms extending from a center, the support arms configured to be attached to a drum of the laundry appliance, wherein the center is configured to receive a shaft of a drive mechanism of the laundry appliance providing rotational motion to the drum during use,   wherein the support arms are formed from a first part and a second part, where the first part is coupled to the second part to form a hollow interior and increase inertia momentum of the spider during use.   
     
     
         2 . The cross-piece of  claim 1 , wherein the support arms form a quadrilateral cross-section. 
     
     
         3 . The cross-piece of  claim 2 , wherein the support arms form a square cross-section. 
     
     
         4 . The cross-piece of  claim 1 , wherein the first part is formed having three sides and wherein the second part has a single side configured to close the three sides of the first part. 
     
     
         5 . The cross-piece of  claim 4 , wherein the three sides of the first part form a trapezoidal shaped cross-section. 
     
     
         6 . The cross-piece of  claim 1 , wherein the first part is coupled to the second part by welds. 
     
     
         7 . The cross-piece of  claim 1 , wherein the first part is made of a first material and the second part is made of a second material. 
     
     
         8 . The cross-piece of  claim 7 , wherein the first material is the same as the second material. 
     
     
         9 . The cross-piece of  claim 7 , wherein the first material is different than the second material. 
     
     
         10 . The cross-piece of  claim 1 , wherein the first part and second part are each formed from a plastic material. 
     
     
         11 . The cross-piece of  claim 1 , further comprising a fill material within the hollow interior to increase wear resistance and inertial momentum. 
     
     
         12 . A crosspiece forming a spider for a laundry appliance, comprising:
 a plurality of support arms extending from a center, the support arms configured to be attached to a drum of the laundry appliance, wherein the center is configured to receive a shaft of a drive mechanism of the laundry appliance providing rotational motion to the drum during use; and   where each support arm includes a first part and a second part, where the first part is coupled to the second part which cooperate to form a quadrilateral cross-section with a hollow interior to increase strength and inertia momentum of the spider during use.   
     
     
         13 . The cross-piece of  claim 12 , wherein the quadrilateral cross-section is a square cross-section. 
     
     
         14 . The cross-piece of  claim 12 , wherein the first part is formed of three sides and wherein the second part is a single side configured to close the three sides of the first part. 
     
     
         15 . The cross-piece of  claim 14 , wherein the three sides of the first part form a U-shaped cross-section. 
     
     
         16 . The cross-piece of  claim 12 , wherein the first part is coupled to the second part by welds. 
     
     
         17 . The cross-piece of  claim 12 , wherein the first part is made of a first material and the second part is made of a second material. 
     
     
         18 . The cross-piece of  claim 17 , wherein the first material is the same as the second material. 
     
     
         19 . The cross-piece of  claim 17 , wherein the first material is different than the second material. 
     
     
         20 . The cross-piece of  claim 12 , wherein the first part and second part are each formed from a plastic material.
