Apparatus for sizing window coverings

Abstract

An apparatus for sizing at a single workstation pleated shades and mini blinds in a particular dimension uses a sizing device that includes hydraulic actuated horizontal and vertical blades and a cutting rail assembly. The hydraulic actuated horizontal and vertical blades are used to respectively cut the components of a pleated shade or a mini blind, such as head rails, bottom rails and a pleated blind or aluminum slats. The horizontal and the vertical blades are sequentially operated to prevent the blades from colliding with each other. The cutting rail assembly has multiple stacked guiding blocks so that the pleated shade and the mini blind can be held in different tiers and be simultaneously cut at the single workstation.

1 . An apparatus for sizing window coverings, and the apparatus comprising: 
 a frame having a top and a control panel;    a control box mounted in the frame and electrically connected to the control panel;    an actuator mounted in the frame and electrically connected to the control box;    a sizing device assembled on the top of the frame and comprising 
 a cutting block fastened vertically on the top of the frame and comprising a working block fastened vertically on the top of the frame and having a front, a rear, a row of upper slots and a row of lower slots, the row of upper slots and the row of lower slots defined through the front to the rear and respectively comprising a head rail slot, a center window and a bottom rail slot that are horizontally arranged relative to the top of the frame;  
 a cutting rail assembly mounted on the top of the frame at the rear of the working block and comprising 
 a supporting rail mounted at the rear of the working block and having a horizontal top; and  
 multiple stacks demountably mounted on the top of the supporting rail, each of the stacks comprising an upper guiding block and a lower guiding block, each of the guiding blocks having multiple transverse passages, and the transverse passages of the lower guiding blocks respectively aligned with the head rail slot, the center window and the bottom rail slot of the row of lower slots in the working block and the transverse passages of the upper guiding blocks respectively aligned with the head rail slot, the center window and the bottom rail slot of the row of upper slots in the working block;  
 
 a horizontal cutter assembly mounted on the top of the frame and comprising two horizontal cutting blades actuated by the actuator and aligned respectively with the center windows; and  
 a vertical cutter assembly vertically mounted in the top of the frame and comprising two vertical cutting blades actuated by the actuator and respectively aligned with the head rail slots and the bottom rail slots;  
   wherein the cutting rail assembly further comprises a ruler horizontally attached on the top of the supporting rail relative to the top of the frame, and the stacks are arranged alongside the ruler.    
   
   
       2 . The apparatus as claimed in  claim 1 , wherein each of the center windows has a first side and a second side opposite to the first side; and 
 the cutting block further comprises an upper cutter anvil and a lower cutter anvil that are fastened vertically on the top of the frame at the first sides of the center windows and aligned respectively with the horizontal cutting blades;    wherein the horizontal cutting blades are sited at the second sides of the center windows.    
   
   
       3 . An apparatus for sizing window coverings, and the apparatus comprising: 
 a frame having a top and a control panel;    a control box mounted in the frame and electrically connected to the control panel;    an actuator mounted in the frame and electrically connected to the control box;    a sizing device assembled on the top of the frame and comprising 
 a cutting block fastened vertically on the top of the frame and comprising a working block fastened vertically on the top of the frame and having a front, a rear, at least one row of slots, the at least one row of the slots defined through the front to the rear and comprising a head rail slot, a center window and a bottom rail slot that are horizontally arranged relative to the top of the frame;  
 a cutting rail assembly mounted on the top of the frame at the rear of the working block and comprising a supporting rail mounted at the rear of the working block and having a horizontal top;  
 a horizontal cutter assembly mounted on the top of the frame and comprising at least one horizontal cutting blade actuated by the actuator and aligned with the center window; and  
 a vertical cutter assembly vertically mounted in the top of the frame and comprising two vertical cutting blades actuated by the actuator and respectively aligned with the head rail slot and the bottom rail slot;  
   wherein the cutting rail assembly further comprises a ruler horizontally attached on the top of the supporting rail relative to the top of the frame.    
   
   
       4 . The apparatus as claimed in  claim 3 , wherein the cutting assembly further has at least one guiding block demountably mounted on the top of the supporting rail, arranger alongside the ruler and having multiple transverse passages, and the transverse passages of the at least one guiding block aligned respectively with the head rail slot, the center window and the bottom rail slot of the at least one row of slots in the working block;  
   
   
       5 . The apparatus as claimed in  claim 4 , wherein: 
 each of the center windows has a first side and a second side opposite to the first side;    the cutting block further comprises at least one cutter anvil fastened vertically on the top of the frame at the first sides of the center window and aligned with the at least one horizontal cutting blade; and    the horizontal cutting blades are sited at the second sides of the center windows.
