The present invention generally relates to building construction, and more particularly to the securing of decking materials requiring mechanical tabs or clips to secure them in place.
Extruded decking boards, composite boards, milled wood planking, and the like, may utilize fasteners such as hidden clips to fasten them in place. These hidden clips consist of a body that may be of molded plastic or stamped metal, and have a screw, nail, or formed tab inserted in it.
During use, the hidden clip is inserted into the groove on the board's edge and the fastener is driven through the clip into the joist supporting it, fastening the board edge to the joist. This is a labor-intensive process since the user must hand position each individual hidden clip, hold it in place with one hand, and nail or screw the fastener with the other hand. This hand feed technique is slow and requires two hands. When a board is on an incline or requires force to position it, two persons may be required to lend the third hand to hold it in position while the hidden clip and fastener are secured.
Thus, there is a continuing need for improved securing systems for decking.
Disclosed is a deck board mounting system for efficiently fastening and mounting hidden clips for decking planks. The disclosure includes a universal magazine that mounts to a hand-operated power tool that will automatically feed attachment clips to the tool head and position them under the nail/screw driving mechanism. This magazine is adaptable to a standard industrial screw gun or nail gun, and utilizes the tool's ability to drive the fastener. The clip feed magazine can be provided in place of the gun's conventional magazine feed components and includes hidden clips provided with a clip strip. The strip includes multiple hidden clips separated by a frangible section or tab located between adjacent clips. Each hidden clip can be formed of a plastic material and include a locating tab defined on each side of the clip's body and fastener aperture defined in a center of the body.
In various embodiments, one or more “dummy” clips can be included at ends of the clip strip and adapted for manual manipulation by a user. In such case, the user would use a conventional screw gun to drive the screw through the clip. The dummy clip facilitates handling of the strip by hand during installation and use, wherein the clips of the strip are manually placed, engaged, and secured to bind the respective clips to the deck board. After use, the dummy clip can be removed from the adjacent clip via severing one or more connecting tabs.
Other embodiments of the hidden clip can include one or more angled or sloped bottom compression tab features provided to facilitate leveling during fixation. The feature can be generally H-shaped, having a first end portion, a second end portion, and an intermediate sloping crossbar portion. The length of the first portion can be measurably longer than the length of the second portion such that the crossbar portion extends transversely between the end portions to define the sloped or angled construct of the compression tab.

Referring generally to
The magazine system 102 includes a magazine feed assembly 102a and a nose or hammer assembly 102b. A yoke mechanism 105 can selectively and hingedly connect a portion of a handle 101 of the tool 100 with a portion of the magazine feed assembly 102a. The magazine 102 can be constructed all or in part of a plastic and/or metal material that holds a strip 116 of clips 104 in queue. When an operator places the driver head of the tool 100 where they want to place or deploy a fastening clip 104, the operator depresses downward on the tool 100. The moveable magazine 102a then travels vertically upward with respect to the tool body, about the yoke mechanism 105, which forces the forward-most clip 104 of the strip of clips 116 in the magazine into a knife edge, which cuts that particular clip from the rest of the strip. When the magazine 102a has reached full down stroke, a rod in the magazine can depress the tool's trigger safety catch. The trigger is then pulled and the hammer of the tool can drive a fastener through the hidden clip 104 to a desired depth, thereby securing the clip 104 to the frame board 108 and securing the deck board 106 in place. As depicted in
Certain embodiments of the magazine feed assembly 102a can be generally straight (e.g.,
The magazine feed assembly 102a can include a bottom indexing and alignment feature 102c. The feature 102c can include extending elongated tabs or protrusions adapted to fit on and around a portion of the deck joist or frame 108 to prevent lateral movement and to provide proper alignment of the tool 100 during use.
In certain embodiments, the alignment feature 102c is generally U-shaped and can include a gap of approximately 2 inches between the extending tabs to accommodate seating and securement with the positioned frame board 108. A length of the feature 102c can be defined in and extend down from each of the magazine 102 halves detailed herein. In other embodiments, the indexing and alignment feature 102c can be provided with other components or assemblies of the present invention to facilitate the described functionality.
The magazine assembly 102a is configured to serially feed the hidden clips 104 one at a time via a moveable thruster or clip receiver mounted in a groove on a hammer guide plate 140. A self-coiling spring 127a disposed within the magazine forces the strip of clips 116 forward.
Referring to
The left side portion 111 includes a side opening or channel 121 extending along a length of the side 111 and adapted to receive a pusher or thruster device or assembly 127. The pusher device 127 can include a knob 125 or like element for manual manipulation by the operator. The pusher device 127 can include an outer slide plate and an inner slide spring retainer. The pusher device 127 slides along the channel 121 to push or drive the clips 104 of the clip strip 116 toward the nose portion 102b of the magazine assembly 102 such that each time a hidden clip securing action is completed, the next clip in line is automatically advanced and ready for fastening. Coil springs and/or a cam drive can be provided to animate the thruster. A slide groove can attach the magazine to the hammer guide plate.
When loading the magazine with a strip of clips 116, for those embodiments using a tool or similar device during operation, the operator pulls or pushes the pusher 127 rearward to a mechanical release catch. The operator then inserts the strip of clips 116 into the empty magazine, via the end cap 119, and releases the catch. The pusher 127 is thus pulled forward by the spring 127a, thereby forcing the leading clip 104a into the insertion locators in the magazine. A cam mechanism can be utilized to advance the strip of clips in an alternative embodiment. The strip 116 can include a wide variety and number of clips 104, ranging from clip 104a . . . 104n.
A stroke limiter adjusts the fastener depth. The depth can be manually adjustable by turning a thumbscrew, CW or CCW, to increase or decrease depth. A rigidly mounted spring steel knife 150 separates the leading clip as the magazine travels upwards into the hammer guide plate. The assembly is secured to the tool via an attachment plate, which is configured to mount to a variety of commercially available power tools.
As illustrated in
The hammer guide plate 140 provides reinforcement and guidance for the tool 100 hammer mechanism as it extends and retracts during use, and the plate gussets 152, 154 define the side boundaries for the hammer guide plate 140. When the tool is in position to fasten a hidden clip to a surface, the user pushes the tool 100 downwards, sliding the hammer guide plate 140 upwards and pushing tab cutter blade 150, secured to the guide plate, into the magazine. Such action causes the blade 150 to cut or shear the leading clip (e.g., 104a) from the strip 116 and align it for driving. The blade 150 can include one or more cutting edges surfaces to facilitate the described cutting.
When the tool 100 is activated, its hammer forces the fastener 126 to a depth, fastening the clip 104 to the joist (or other surface) below. Each time a hidden clip 104 securing action is completed, the next clip in line is automatically advanced and can be securely located via its tab/recess so that it is ready for fastening.
The lateral protrusion magazine tabs 114 can be made very small (e.g., 20 thousandths of an inch) so that the tabs 114 do not affect the placement of the clip 114 within the groove 107 of the board 106. The magazine tabs 114 in other embodiments can be in the form of a frangible film, either perforated or non-perforated, connecting the adjacent clips. This film in such configuration defines a tear line between adjacent clips.
As depicted in
In use, the tabs 120 bind the clip 104 to the deck board 106 when compressed. A dead stop 122 can be defined adjacent to the compression tabs 120 to define the maximum compression at which the clip is seated. A crush aperture or hole 123 can also be defined in the body 110 to allow for future expansion/contraction of adjacent deck boards/flooring. The compression tabs 120 can also provide a universal component to work with different brands of decking with varying center lines, mounting grooves, and like construct requirements.
The strip 116 of clips can be pre-loaded with the fastener 126 as discussed above. This configuration is useful when utilizing the power tool 100 discussed herein. The pre-loaded fasteners 126 in the strip 116 of clips moves the fastener automatically into alignment with the drive head of the tool. This allows the user to advantageously operate the tool with one hand while holding the deck board with their other hand. This allows the user to install the beck boards far faster than the conventional multi-step method of one-at-a-time hand-placed clips and individually placed fasteners for clip, followed by use of a conventional power tool. The pre-loaded fasteners can also be provided for single clips and strips of clips configured for manual installation.
As shown in
A wide variety of fasteners can be used with the clips described herein. Additional example fasteners include concrete screws for fastening the clips to a concrete substrate instead of to wooden joists 108.
The hidden clip 104 of
The particular clip 105 most remote from the dummy clip 105 is secured to the board with a fastener. After that particular clip 104 is secured, the operator or user can torque the remaining strip of clips 104, or otherwise facilitate breaking, of the secured clip 104 from the strip 116 at the respective frangible tabs 114. This process is repeated until the last clip, which is adjacent to the dummy clip 105, is secured in place. The dummy clip 105 can be removed from the adjacent clip 104 at tabs 114.
Other versions of this embodiment can be adapted for use with a power tool and magazine as well. For example, the dummy clip 105 can be removed prior to insertion of the strip into the magazine of a power tool as discussed herein.
In operation, the extending lip of the top portion 110a is inserted within the side groove 107 of a corresponding decking board 106. As detailed herein, the fastener 126 (e.g., a screw) extends through the clip aperture 112 to engage with, and threadably secure to, the underlying deck frame 108. With this embodiment having the sloped compression tab feature 120, the clip 104 is forced to level out parallel to the base of the groove 107 as the fastener 126 sets to its final engagement depth during fixation. The bottom angled structure of the compression tab 120 combats or counters the tendency the clip 104 may have to tilt upon tightening securement, while still promoting biting engagement.
As can be appreciated, the user can operate the present invention with one hand while holding the deck board in place. The user also need not reload the tool for each hidden clip to be installed. Thus, the installation process requires less installers and installer time. This reduces costs and improves productivity.
Because various clips of the present invention are bilaterally symmetrical along a plane bisecting the clip along its midline to define front and back halves, the clip can be fastened in either forward or rearward orientations about the vertical axis. Thus, the entire strip of such clips can be inserted into the magazine beginning with either end. This means that the user cannot insert the strip backwards since the front end and rear ends of the strip are the same (e.g., interchangeable). The clips can also be bilaterally symmetrical along a plane bisecting the clip along its midline to define right and left halves.
The clips can be formed of a single material or multiple separate materials. For example, the clips can all comprise single type of plastic material. Alternatively, each clip may comprise multiple different materials in order to provide specialized properties such as those discussed herein.
While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it will be apparent to those of ordinary skill in the art that the invention is not to be limited to the disclosed embodiments. It will be readily apparent to those of ordinary skill in the art that many modifications and equivalent arrangements can be made thereof without departing from the spirit and scope of the present disclosure, such scope to be accorded the broadest interpretation of the appended claims so as to encompass all equivalent structures and products. Moreover, features or aspects of various example embodiments may be mixed and matched (even if such combination is not explicitly described herein) without departing from the scope of the invention.
