The present invention relates to cutting apparatus and methods for trimming window coverings such as window blinds that are trimmed at the time of purchase at retail stores.
Different approaches have evolved to prepare window blinds and other window coverings to be of the dimensions needed to cover a particular window (or other architectural opening) for a specific customer. In one approach, an installer or decorator measures the opening to determine the appropriate dimensions, and a window covering is ordered from the manufacturer or fabricator, where the blind is built to the required dimensions. The completed blind is shipped and installed. While custom manufacturing normally provides a blind of the appropriate size, a disadvantage of this procedure is the time required, whereby several days or even weeks may elapse from initial measuring to final installation. Custom manufacturing also can be expensive.
Another approach involves manufacturing and supplying retail stores with blinds in a number of “stock” sizes for each blind variety. The customer then selects a size that most closely approximates the size of the window to be covered. However, if only a small number of stock sizes are provided, the likelihood of a customer finding a stock size that fits appropriately is reduced. Providing more stock sizes can mitigate fitting difficulties; however, to do so necessarily requires retailers to take on greater inventory and provide more shelf space for the blinds being stocked.
A solution to the foregoing problems has led to a now popular approach, a so-called “size-in-store” system, in which a relatively small number of stock sizes of each blind are provided to the retail outlet. The blinds are designed in a manner such that the headrails, slats (or other window covering materials) and bottom rails can be trimmed at either and preferably at both ends. “Size-in-store” programs from manufacturers typically include providing the retail store outlet with a cutdown machine designed to cut the particular blinds or other window coverings. When a store handles different types of window coverings, it has been necessary to have different cutdown machines for the different products, requiring dedicating space to numerous cutdown machines that could be used otherwise for the display of products.
While many different types of cutdown machines exist, certain characteristics are common to many of the machines. Typically, the machines include means for cutting the headrail, the slats (or other window covering material) and the bottom rail of the window covering. In certain situations, different approaches and tools are used to cut the headrail, the slats and/or the bottom rail. In other designs, two or more components are cut by one of the cutting implements. Additionally, known cutdown machines allow for cutting both sides of the window covering, to provide a trimmed window covering having an attractive finished look with the amount that is cut from each component being approximately the same. However, the machines and methods are not always adequate in providing systems for sizing window shades efficiently and accurately. For example, some of the systems are too complex to be operated by a typical retail salesperson having only an average amount of training and experience.
A cutdown program may include multiple product lines requiring several different machines with which to cut them. End stop adjustments and cutting instructions vary from one cutdown machine to another. Untrained, inexperienced or new store associates often have difficulty with correctly setting and operating the machines. When mistakes are made in trimming blinds, it is often necessary to discard a blind and start over, thus impacting the profitability of the program.
Another problem that has been encountered in cutdown programs for vertical blinds is that a vertical blind may have a headrail that is longer than the width of a standard bay opening in the store. Cutdown machines for such blinds have had to be located in areas that are not restricted by the framework of display bays. This can be some distance from the location for displaying and selling other window covering materials.
Therefore, there is a need for a cutting apparatus for window treatments capable of customizing window treatments efficiently, to fit window dimensions specified by customers. Also, there is a need for a cutting apparatus for cutting a window covering to a specified width, whereby the entire window covering, namely the headrail, the bottom rail and the window covering material are all cut in one setting of the machine, thereby saving time and reducing operator errors. Moreover, the cutting apparatus should produce a final product having a high quality and a professionally cut appearance. Further, there is a need to provide a cutdown machine that can be used to cut window coverings of different styles and types. Still further, there is a need for a window covering cutdown machine that is simple to operate and capable of cutting many different types of window coverings on a single machine requiring minimal space. Yet further, there is a need for a window covering cutdown machine that can be installed in a standard display bay opening, yet can be adjusted to cut head rails and other window covering materials of lengths longer than the width of the bay opening.
The present invention provides a window covering cutdown machine that can be used for cutting window coverings of various types and of various materials, including but not limited to wood and other natural materials, faux wood, solar shades, vinyl shades, vinyl blinds, cellular blinds, and both vertical and horizontal coverings. The machine incorporates multiple discrete cutting centers or stations in a compact arrangement that is convenient to use. The machine can be used for cutting window coverings having a length longer than the width of a standard bay in warehouse style home improvement stores having fixed display racks.
The invention in one form is directed to a cut down machine for cutting window blind products of different types, with a window blind support surface; first and second window blind cutting stations on opposite ends of the support surface; and a third window blind cutting station extendable outwardly from the front of the cutdown machine.
The invention in another form is directed to a cut down machine for cutting window blind products of different types, with a window blind support surface. The machine has a miniblind cutting station at one end of the window blind support surface positioned for receiving ends of miniblinds supported by the window blind support surface, a wood and faux wood cutting station having a saw at an opposite end of the window blind support surface from the miniblind cutting station, the wood and faux wood cutting station being positioned for receiving ends of wood and faux wood blinds supported on the window blind support surface; and a vertical blind headrail cutting station including a headrail clamp movable toward and away from the support surface and having a retracted position beneath the window blind support surface, and a headrail die movable toward and away from the miniblind cutting station.
The invention in still another form is directed to a cut down machine for cutting window blind products of different types, including vertical blind headrails and louvers. The cutdown machine has a window blind support surface, a plurality of cutting stations for receiving ends of window blinds supported by the window blind support surface; and a vertical blind headrail cutting station including a headrail clamp movable between a stowed position beneath the window blind support surface and a use position outwardly from an edge of the window blind support surface, and a headrail die near an end of the window blind support surface.
An advantageous feature of at least one form of the present invention is that a single machine is provided for cutting common window covering types sold in cutdown programs, and fewer machines are needed requiring less space.
Another advantageous feature of at least one form of the invention is that while a single machine is provided, the various cutting stations are independent of one another at various locations around work surface 102. Accordingly, if one station is out of service for repair or maintenance, other work stations are not necessarily affected and can be used.
Still another advantageous feature of at least one form of the invention is that headrails longer than the width of a standard bay can be cut on a machine installed in a bay.
The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention will be better understood by reference to the following description of an embodiments of the invention taken in conjunction with the accompanying drawings, wherein:
Corresponding reference characters indicate corresponding parts throughout the several views. The exemplifications set out herein illustrate embodiments of the invention and such exemplifications are not to be construed as limiting the scope of the invention in any manner.
Referring now to the drawings, and more particularly to
Cutdown machine 100 is a compact, multiproduct cutting center providing convenient access for cutting all common window coverings products sold through in-store cutdown programs. Work surface 102 provides a large, central, table-like surface on which various products can be prepared for cutting at different locations toward one end or the other of cutdown machine 100. Four separate product cutting stations are provided in locations at each end of work surface 102, generally above and behind work surface 102 and generally below and in front of work surface 102.
A miniblind cutting station 106 is provided at one end of work surface 102. An upper cutting station 108 is provided generally above and behind work surface 102 and miniblind cutting station 106. Upper cutting station 108 is suitable for cutting cellular blinds and louvers for vertical blinds. Drawer 104 and an extendable die cutter assembly 110 adjacent miniblind cutting station 106 provide a vertical blind headrail cutter 112. A wood/faux wood cutting station 114 is provided at the end of work surface 102 opposite from miniblind cutting station 106. Wood/faux wood cutting station 114 utilizes both die cutting and a band saw, as will be shown and described subsequently herein. An operator input panel in the nature of a touch screen controller 116 is provided above work surface 102. Activation buttons 118 are provided near each end of machine 100. Alternatively, operation of cutdown machine 100 can be an automatic sequence commenced via touch screen controller 116.
It will be readily understood by those skilled in the art that the general arrangements and configurations of cutting stations shown and described herein are merely exemplary in nature. The cutting stations shown at one end of work surface 102 can be provided at the opposite end of work surface 102, essentially reversed right for left from that shown and described. Further, while miniblind cutting station 106, upper cutting station 108 and extendable die cutter 110 are grouped together at one end of work surface 102, it should be understood that other arrangements are possible, grouping one or more of upper cutting station 108 and/or extendable die cutter 110 at the opposite end with wood/faux wood cutting station 114.
With reference now particularly to
In the exemplary embodiment for miniblind cutting station 106 shown in the drawings, a headrail cutting die 130 and a bottom rail cutting die 132 are provided on opposite ends of a slat opening 134 for receiving and cutting a headrail 131, a bottom rail 133 and a group of slats 135, respectively, of a miniblind 136. Die cuts of the headrail and bottom rail are performed in known fashion, and the slats are cut by a knife-like blade as known in the art. An automatic end stop system 138 (
Headrail die 130 and bottom rail die 132 are separately and independently mounted and can be adjusted relative to one another to vary the space therebetween. Accordingly, die holders 140, 142 for headrail die 130 and bottom rail die 132 are slidably mounted on a rail 144 and can be laterally adjusted via an actuator or actuators 146. The capability of providing variable spacing accommodates cutting different sizes and/or types of miniblinds having more slats or more slat volume per slat to be cut in slat opening 134. In the closed and packaged form from which a miniblind is commonly cut, a smaller blind having fewer slats or thinner slats defines a smaller space between the headrail and bottom rail thereof than does a blind of another size or type having more slats or thicker slats. Thus, to position different blinds suitably between headrail cutting die 130 and bottom rail cutting die 132 may require different spacing between headrail die 130 and bottom rail die 132.
As shown in
Cellular blinds are cut at upper cutting station 108, which is provided at the upper edge of machine 100, generally above and behind work surface 102 and miniblind cutting station 106. Upper cutting station 108 includes a throat 160 (
Vertical blind components are cut in two locations. As mentioned previously, drawer 104 at the front of cutdown machine 100 is pulled outwardly to measure and support a vertical blind headrail assembly 180, which is cut in a vertical blind headrail die 182 that is moved from its stored position as shown in
Drawer 104 is suspended and moveable on telescoping drawer slides 184 of sufficient rigidity and strength to hold drawer 104 in an outwardly extended position without unacceptable deflection or bending while supporting a vertical blind headrail. Drawer 104 includes sides 186, 188 and an angular front panel 190. A ruler 192 having increments thereon for inside and outside mounting calibrations for headrail measurement is provided on angular front panel 190. Ruler 192 can be provided as an adhesive overlay on angular front panel 190; as an insertable card held on angular front panel 190; as a graphic image printed, transferred, painted or otherwise applied onto the surface of angular front panel 190 or in any other suitable stable form on angular front panel 190.
A hairline sight 194 is attached to a sliding clamp 196 which holds headrail assembly 180. By sliding clamp 196 along a track 197 (
In the enlarged views of
When vertical blind headrail cutter 112 is not in use, drawer 104 and extendable die cutter assembly 110 are pushed inwardly to stored positions and therefore and do not protrude outwardly from cutdown machine 100. When a vertical headrail is to be cut, drawer 104 and extendable die cutter assembly 110 are pulled outwardly to receive headrail assembly 180. Even in the outward extended positions thereof, drawer 104 and extendable die cutter assembly 110 do not protrude significantly in front of cutdown machine 100. When the headrail cut has been completed, and after the headrail has been removed, drawer 104 and extendable die cutter assembly 110 are pushed back to the stored positions therefor.
Wood and faux wood cutting station 114 is shown in
Headrail cutting die 230 can be of construction and operation similar to the various headrail cutting dies described previously herein. Headrail cutting die 230 defines a headrail channel piece aperture 240 and a headrail shaft aperture 242. While a single headrail channel aperture 240 and headrail shaft aperture 242 are shown in the drawings, it should be understood that multiple die apertures can be provided for cutting head rails of different configurations.
Band saw 232 can be a standard, commercially available band saw unit and includes a continuous band blade 244 of suitable size and saw tooth configuration and count for cutting the materials to be cut thereon. It is expected that universal, multi-material blade types may be used, to provide versatility in the types of materials that can be cut on cutdown machine wood/faux wood cutting station 114, which may include metals including steel and aluminum, wood and faux wood materials, and synthetic materials such as various plastics. As those skilled in the art will understand, band saw 232 can also have a multi-speed operation through use of a multi-speed motor, or a belt drive system having selectable pulley variations for changing the speed of blade 244. Continuously variable and multiple fixed speed drives are known, and may provide advantages in using cutdown machine 100 on different types of coverings for architectural openings. Band saw 232 further includes an upper compartment 246, a lower compartment 248 and a vertical support 250 extending between upper compartment 246 and lower compartment 248. As those skilled in the art will readily understand, blade 244 rotates along a path between upper compartment 246 and lower compartment 248, which includes a segment through vertical support 250. The various drive, speed control and guide mechanisms discussed above, including a suitable motor, are contained in upper compartment 246, lower compartment 248 and vertical support 250, in known manner.
When using machine 100, an operator enters cutting information via touch screen controller 116. The information entered may include the stock length and type of the blind to be cut, the desired final dimension, and whether the installation is for an inside mount or an outside mount. The stock information about the blind also can be entered by way of a bar screen scanner connected to controller 116. An appropriate scanner can be mounted on the present machine for scanning, or a handheld scanner can be used. The various necessary apparatus for cutting the type of blind designated through such entry information are enabled while other components of cutdown machine 100 not required for cutting the particular window covering to be cut will remain disabled. The end stops are positioned automatically in response to the data input. The blind is then inserted through the appropriate openings or dies until it engages the end stop. Thereafter, the machine is actuated by depressing activation buttons 118 near either end of the machine, or by enabling automatic sequencing entered at touch screen controller 116. Cutting by the band saw or by the various dies is automatic and requires no further operation. After one side of the blind has been cut, the cut end is removed from the particular cutting station which was used, the blind is rotated 180° and the yet uncut side is inserted into the appropriate cutting station. Thereafter, the machine is actuated a second time and automatically cuts the necessary amount for the final dimension desired.
Machine 100 has an open design for easy use by store personnel. Access is open and unencumbered, with work surface 102 being easily accessed without obstruction in front thereof. Accordingly, it is convenient to unpackage a window covering, prepare the window covering for cutting, and slide the window covering into the appropriate cutting station to the left of work surface 102, to the right of work surface 102, above work surface 102 at upper cutting station 108 or below and in front of work surface 102 in vertical blind headrail cutter 112.
An advantageous feature of one form of the present invention is that while a combined apparatus is provided for cutting all types of blinds, the various cutting stations are independent of one another at various locations around work surface 102. Accordingly, if one station is out of service for repair or maintenance, other work stations are not necessarily affected and can be used. The wood and faux wood cutting station, the miniblind cutting station, the vertical blind headrail cutting station and the upper cutting station are separately operated.
Another advantageous feature of another form of the invention is that the various dies, including dies 130, 132, 182 and 230, as shown in the drawings, are held in place by screws or bolts 252. Accordingly, each is easily replaceable, and dies for different headrail or bottom rail profiles can be changed quickly and easily. Repair in the event of damage also is facilitated.
While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
