The present disclosure relates to fasteners, and, more particularly, to a screw magazine and collating screws.
A wide variety of fastener configurations for securing structural members to other members are known. In one example, a screw may be used for securing decking members to associated joists in the construction of an exterior deck, or the like. The screw may be driven into decking members using, e.g., a hand-held or a power fastening tool such as a power drill/driver. When driving screws into decking members, it can be cumbersome to handle each screw individually, orient the screw with respect to the decking member and the drive bit of the fastening tool, and then hold the screw in the desired orientation while driving the screw.
To achieve improved efficiency in driving the screws, there is a need for a magazine for holding a plurality of screws and feeding successive screws into a position relative to a drive bit for driving the screws using a power fastening tool. There is also a need for collating a plurality of screws.
For a better understanding of the present invention, together with other objects, features and advantages, reference should be made to the following detailed description which should be read in conjunction with the accompanying figures, wherein:
The present disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The examples described herein may be capable of other embodiments and of being practiced or being carried out in various ways. Also, it may be appreciated that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting as such may be understood by one of skill in the art. Throughout the present description, like reference characters may indicate like structure throughout the several views, and such structure need not be separately discussed. Furthermore, any particular feature(s) of a particular exemplary embodiment may be equally applied to any other exemplary embodiment(s) of this specification as suitable. In other words, features between the various exemplary embodiments described herein are interchangeable, and not exclusive.
For ease of explanation, systems consistent with the present disclosure may be shown and described herein in connection with various example embodiments and screw configurations. It will be recognized, however, a system and method consistent with the present disclosure will be useful in connection with a wide variety of screw configurations including screws having a head configured to receive a drive bit, lag screws, etc. In addition, exemplary embodiments may be described herein in connection with fastening decking members to associated joists. The decking members may be constructed from any type of material including wood, composite materials, concrete, metal, plastic, textiles, and other materials. Also, it is to be understood that a system and method consistent with the present disclosure may be useful in connection with fastening other type of member constructed from any type of material. The exemplary embodiments described herein are thus provided only by way of illustration and are not intended to be limiting.
In some embodiments, a collated screw magazine consistent with the present disclosure may include a magazine body configured to receive a strip of collated screws at a loading end of the magazine body. A pusher coupled to the magazine body is configured to engage at least one screw of the strip of collated screws to urge the at least one screw toward a discharge end of the magazine body opposite from the loading end of the magazine body. A bit opening at the top of the magazine body configured to receive a drive bit for driving the at least one screw through a discharge opening at a bottom of the magazine body. A magazine consistent with the present disclosure may facilitate driving multiple screws into a material while avoiding the cumbersome process of handling one screw at a time. This can improve the speed and efficiency of driving multiple screws, e.g., in constructing a deck or floor.
Systems and methods consistent with the present disclosure may be implemented in a variety of configurations.
Once the forward most screw 126a is driven into the decking board or other material, the magazine body 100 may advance the next screw 126 in the collated strip 110 of screws 126 into the forwardmost position and into alignment with the bit opening 131. This process may continue with respect to all the screws 126 in the collated strip 110 of screws 126. Once all the screws 126 in the collated strip 110 of screws 126 are driven, another collated strip 110 of screws 126 may be loaded into the magazine body 100 for driving into the decking board or other material.
In the illustrated example embodiment, the screws 126 are advanced by a pusher 113 coupled to a carriage assembly 109 slidably mounted on side rail 127 of the magazine body 100. The carriage assembly 109 includes a carrier 115, a compartment 116, a carrier spring 118 spring, and the pusher 113. The carrier 115 is slidably coupled to the side rail 127 for movement between the discharge end 107 and the loading end 106. The compartment 116, the carrier spring 118 and the pusher 113 are coupled to the carrier 115 for slidable movement therewith.
As illustrated in
The pusher 113 includes a pusher head 129 and a pusher tip 111. The pusher 113 is coupled to the carrier 115 by a pivot pin 112 positioned between the pusher head 129 and the pusher tip 111. The pusher head 129 is biased away from the carrier 115 by a pusher head spring 114, e.g., a coil spring, disposed between the pusher head 129 and the carrier 115. The coil spring 114 biases the pusher 113 to pivot around the pivot pin 112 and forces the pusher tip 111 toward the strip 110 of collated screws 126. The pusher tip 111 may extend between any adjacent screws 126 of the strip 110 of collated screws 126. Under the bias force of the carrier spring 118, the pusher tip 111 urges the screws 126 of the strip 110 of collated screws 126 toward the discharge end 107 to position the forwardmost screw 126a into alignment with the bit and screw guide 101.
When a new collated strip 110 of screws 126 is loaded into the magazine body 100, the strip 110 may be inserted into the loading end 106 and forced all the way forward to the discharge end 107. A user may depress the pusher head 129 to force the pusher head 129 toward the carrier 115 and rotate the pusher tip 111 away from the strip 110. The user may then force the carriage assembly 109 rearward to the loading end 106 and release the pusher head 129 so that coil spring 114 rotates the pusher 113 about the pin 112 and the pusher tip 111 extends between any adjacent screws 126 of the strip 110, as shown in
With particular reference again to
Another endplate 102 may be installed at the discharge end 107 of the magazine body. The endplate 102 can include a screw stop locator 119, that locates the screw that is to be driven relative to a drive bit and the screw and bit guide 101. As shown also in
A wear plate 104 may be provided to define at least a portion of the bottom 133 of the magazine body 100 protect the material in contact with the magazine body 100 contact from damage. The wear plate 104 may be held in place with flat head screws 105. The thickness of the wear plate 104 may be selected based on the materials with which the magazine 10 will be used.
In some embodiments, a spacer 136 may be coupled to the magazine body 100 to extend outwardly from a side thereof, e.g., from the side of the substrate stop 135. The distance by which the spacer 136 extends from the side of the magazine body 100 may be selected to establish a desired space between adjacent deck boards. In use, the magazine 10 may be placed on the deck board 137 to be fastened to the joist 138 with the spacer 136 in contact with the adjacent deck board to achieve the desired spacing between adjacent deck boards.
In the illustrated example, the front plate 302 includes a spacer pin channel 304 defined therein and first 306 and second 308 locking channels defined therein and intersecting the spacer pin channel 304. The first locking channel 306 is substantially horizontal and intersects the spacer pin channel 304 near the top of the plate 300. The second locking channel 308 is substantially horizontal and intersects the spacer pin channel 304 below the first locking channel 306 and closer to the bottom of the plate 300. The spacer pin channel 304 extends substantially vertically from the second locking channel 308 and through the top of the plate 300. The top of the spacer pin channel 304 may be closed by a removable cap 310 to prevent the spacer pin 302 from sliding out of the spacer pin channel 304. A spacer pin bore 312 is formed in the plate 300 in alignment with the spacer pin channel 304 and extends through the bottom of the second locking channel 308, through the bottom of the plate 300 and through any wear plate 104.
The spacer pin 302 is removably attachable to the plate 300 and positionable in a use position and a stored position. In the illustrated example, the spacer pin 302 is generally L-shaped having a long first leg 314 and a shorter second leg 316. The first 314 and/or second 316 legs of the spacer pin 302 may have a round or non-round cross-section. The spacer pin channel 304 is sized to receive the first leg 314 of the spacer pin 302 and the first 306 and second 308 locking channel are sized to receive the second leg 316 of the spacer pin 302.
To install the spacer pin 302 in the plate 300, the first leg 314 of the spacer pin 302 may be positioned in the spacer pin channel 304 with the second leg 316 extending in a forward direction relative to the front plate 300. The first leg 314 of the spacer pin 302 may be moved downward in the spacer pin channel 304 until the second leg 316 is substantially vertically aligned with the first 306 or second 308 locking channel. The spacer pin 302 may then be rotated with the first leg 314 in the spacer pin channel 304 until the second leg 316 is received by the first 306 or second 308 locking channel. In this position, the spacer pin 302 is vertically and removably held in the first 306 or second 308 locking channel.
The first locking channel 306 may be positioned to removably hold the spacer pin 302 in a position where the spacer pin 302 does not extend through the spacer pin bore 312 and out of the bottom 133 of the magazine body, as shown in
When a user desires to use the spacer pin 302, the second leg 316 of the spacer pin 302 may be rotated with the first leg 314 in the spacer pin channel 304 and into the second locking channel 308. When the second leg 316 is in the second locking channel 308 the first leg 314 of the spacer pin 302 extends downwardly from the magazine 10a, e.g., as shown in
The width of the first leg 314 of the spacer pin 302 may be selected for establishing a desired spacing between decking boards and may be between about 1/16″ and 1″. In some embodiments, the first leg 314 of the spacer pin 302 may have a width of ⅛″, 3/16″, or ¼″. To facilitate storage of multiple common sizes of spacer pins 302, the plate may include one or more storage bores 318 extending into and through the front surface of the plate 300. The first leg 314 of a spacer pin 302a may be inserted into a storage bore 318 and into a storage space in the magazine body 100. The second leg 316 of the spacer pin 302a may be rotated to rest adjacent the front surface of the plate 300, e.g., as shown in
With particular reference to
The support pin 402 may be generally L-shaped with a first leg 404 and a second leg 406. The first 404 and/or second 406 legs of the support pin 402 may have a round or non-round cross-section. In some embodiments the support pin housing 400 may be coupled to a side of the magazine body 100 and may include a support pin bore 408 therethrough that extends through and the magazine body 100 and any wear plate 104.
To place the support pin 402 in a use position, e.g., shown in
To place the support pin 402 in a storage position, e.g., as shown in
The spring 124 extends outwardly from the housing 123 toward the drill and bit guide 101 and an opposite end 150 of the spring 124 is fixed to a top portion of the housing 123. As the forwardmost screw 126a is driven through the magazine body 100a, the chuck 125 of a power fastening tool, e.g., a drill or impact driver, will come in contact with the spring 124. This contact will push the end 139 of the spring 124 feeder back toward the loading end 106 and behind the next screw 126 in the strip 110 and advance the screw 126 forward when the driver 108 is removed from the magazine body 100a.
As described above, screws 126 may be provided in a strip 110 and may be fed into the magazine body 100 for driving. Strips 110 of collated screws may also be used without the magazine 10, 10a, 10b described above. To facilitate use without a magazine, the screws, e.g., screws with a head driven by a bit or lag screws, may be collated and coupled to a rigid support. The rigid support may be configured to be grasped by a single hand of a user without touching a screw the user intends to drive into a material. In this way the rigid support allows the user to position the screw to be driven by grasping the rigid support and moving the rigid strip until the screw is in a desired position and orientation. Thereafter, the other hand of the user can grasp a driver, e.g., a hand-held screwdriver or power fastening device, place a bit or socket of the driver into engagement with the head of the screw, and drive the screw into material while holding the rigid support in one hand and the driver in the other hand.
Collating the screws 126 and coupling them to a rigid support provides several advantages compared to handling loose screws that may need to be individually selected from a container and positioned for driving. For example, collating screws 126 and coupling them to a rigid support for hand-held use with a power driver may prevent injury to a user in case the driver bit slips off the screw head, as fingers are kept away from the driver path. Collating multiple screws 126 in a strip and coupling them to a rigid support also obviates the need to hold a handful of loose screws and may prevent injury to the user from the points of screws when reaching in a bag or box for more loose screws.
Consistent with the present disclosure, a collated strip coupled to a rigid support may use any size screw, e.g., from ½″ long to 8″ long in some embodiments. In some embodiments, the screws can be 1/16″ diameter to 1″. Any number of screws may be collated and coupled to the rigid support, depending for example on screw size. The term “rigid” as used herein with reference to a rigid support, means the support is sufficiently rigid to retain the collated screws and allow a user to position a selected screw in a desired position and orientation. The rigid support may be plastic, or non-plastic and round or non-round. The rigid support may be made of all one type of material, or of multiple materials. For example, the rigidity may be provided by one material, while the adhesion and collating can be provided by another material. Collating can be done in one pass, or multiple.
