This application claims priority on basis of previously filed Canadian Patent Application No. 2,680,727 filed Sep. 25, 2009.
BACKGROUND OF INVENTIONThis invention relates to fences, barriers, panels for constructing fences and barriers, kits for constructing a fence panel or barrier, and connecting devices for connecting fence panels to posts.
A variety of fence constructions and barrier constructions are known in the fencing art including picket-type fences that include fence posts, horizontal rails extending between the posts and a series of vertical pickets or bars that are mounted on the rails. Picket-type fences are often used for security or ornamental purposes. A variety of materials have been used to construct picket-type fences including wood, steel, iron and aluminum. The assembly of such fences often requires several tools, some of these tools being used to install various fastening devices that couple the pickets, rails and posts. In the case of a metal fence, particularly a fence made of steel or iron, the components can be welded to one another. However these known methods of fence construction can often lead to premature rusting. Indeed the known fasteners for fences and welds can rust before other fence components. Furthermore welded joints generally provided little, if any flexibility in the fence construction.
Custom fabricated fences made of iron and steel are well known and have been used for many years. However with such welded fences, there are known difficulties including those already mentioned. It can be difficult for the metal components to be fitted together due to the problem of making field measurements and the metal components have no built-in adjustability feature. It can also be difficult to fully grind and polish the welds in order to provide a pleasing, finished appearance. Furthermore, the heavy, relatively large components used to construct many metal fences can be costly to transport because of their bulk and weight.
Aluminum fence constructions are also known in the fencing art, but it can be hard to construct an aluminum fence by welding the components together. Because of these difficulties, aluminum fences often employ components that are mechanically fastened together but the use of such fasteners can result in fences that do not have a pleasing appearance because the fasteners are often visible. Such modern fence systems can also cause problems if the fence line is not straight or the fences need to be installed on a slope or uneven terrain.
U.S. Pat. No. 5,454,548 issued Oct. 3, 1995 to R. S. Moore describes a fence construction wherein tubular members are joined at right angles to form a fence or barrier. A series of poles or bars having a square cross section are inserted through pre-punched holes formed along horizontally extending fence rails. Both the pickets and rails can be hollow tubes made of iron or aluminum. The ends of the horizontal rails can be supported by means of brackets which secure the rails to either posts or walls. Elongate coupling bars can be used to secure the vertical poles or pickets in the rail openings through which they extend.
More recent U.S. Pat. No. 7,025,335 issued Apr. 11, 2006 to A. Q. Zhu describes a modular picket fence wherein horizontal rails are connected to vertical posts by means of U-shaped brackets. The rails are formed with a series of spaced apart apertures through which the vertical pickets extend. A locking member is assembled inside each end portion of each picket and this member has spring biased stoppers that extend through transverse apertures in an end section of the picket and also extend into the adjacent horizontal rail when the end portion of the picket is inserted into the rail.
In view of the known difficulties with existing fence constructions, there is a need for an improved fence or barrier panel, an improved kit for constructing a fence panel or a barrier panel, and improved connecting devices for connecting fence panels to fence posts.
SUMMARY OF THE PRESENT DISCLOSUREAccording to one embodiment of the present disclosure, a kit for constructing a fence panel or barrier panel includes a lower rail and an upper rail with these rails being formed with bar-connecting holes distributed along their lengths. These rails are adapted to extend horizontally in an assembled fence with the lower rail extending parallel to the upper rail. The kit further includes first bar sections for mounting between and connecting the upper and lower rails so as to form a fence panel. Each bar section in use extends between an aligned pair of the holes in the upper and lower rails. There are also provided second bar sections each connectable to a respective one of the first bar sections to form a bar and mountable on the upper rail so as to extend upwardly from a respective one of the bar connecting holes in the upper rail. Also upper connecting devices are provided for joining upper ends of the first bar sections to the upper rail and to the second bar sections. Lower connecting devices are provided to join lower ends of the first bar sections to the lower rail by means of bar connecting holes formed therein. When the fence or barrier panel is constructed, the first and second bar sections extend substantially perpendicular to the upper and lower rails.
In an exemplary version of this kit, each of the upper connecting devices includes a threaded axial passage in an upper end section of its respective first bar section and a threaded end section of the second bar section connectable to its respective first bar section by being threaded into the axial passage.
According to another embodiment of the present disclosure, a kit for constructing and mounting a fence panel for a fence having a plurality of posts includes elongate rails adapted for mounting horizontally between adjacent posts so that upper and lower rails can extend substantially from one post to an adjacent post when the fence is erected. The kit includes a plurality of bars adapted for mounting between and joining the upper and lower rails in order to construct the fence panel. The bars in each panel include two end bars located at opposite ends of the fence panel. A plurality of connectors for attaching the end bars to adjacent posts of the fence are provided. Each connector includes a collar section with a bar-receiving hole whereby when one of the end bars is inserted through the bar-receiving hole of the respective connector, the connector is at least initially free to pivot about and along the one end bar for connecting and adjustment purposes. Each connector further includes an end section spaced from the collar section and adapted for fixedly joining the connector to an adjacent post.
In an exemplary version of this kit, each kit comprises an assembly that includes a collar pin, a separate elongate sleeve member having an axial passageway formed therein, and a threaded adapter providing the end section which can be joined to the post. The collar pin provides an elongate shaft section adapted for insertion in the axial passageway. The collar section is connected to one end of this shaft section.
According to still another embodiment of the present disclosure, a fence panel for constructing a fence includes an elongate upper fence rail and an elongate lower fence rail extending substantially parallel to the upper fence rail. These two rails have a number of bar-connecting holes formed therein and distributed along their lengths. First bar sections extend between and connect the upper and lower fence rails with each first bar section extending from one of the holes in the lower fence rail to one of the holes in the upper fence rail. Separate second bar sections are each connected to a respective one of the first bar sections to form an elongate bar. Each second bar section extends upwardly from a respective one of the holes in the upper fence rail. The second bar sections are mounted on the upper fence rail. The panel also includes means for connecting bottom ends of the first bar sections to the lower fence rail using the bar-connecting holes in this rail.
According to an exemplary form of this panel, each of the first and second bar sections has a threaded end section and each first bar section is threadably connected to its respective second bar section by means of their threaded end sections at the upper rail.
According to a further embodiment of the invention, a connecting device for connecting a fence panel to a post is provided. The panel has a series of picket members and horizontal rails connecting the picket members together. The connecting device comprises a collar pin having an elongate shaft section and a collar section secured to an end of the shaft section. The collar section has an aperture for receiving snuggly one of the picket members. The connecting device further includes an elongate connecting member formed with a central passageway and adapted to receive the shaft section in the passageway. This connecting member has a first thread mechanism for securing the shaft section in the central passageway. There is also an adapter for securing one end of the connecting member to a fence post, this adapter having a second thread mechanism for securing the connecting member to the adapter.
In an exemplary form of this connecting device the first thread mechanism comprises a screw member and a threaded screw hole in a side of the connecting member for receiving the screw member.
These and other aspects of the disclosed fence kits, fence panels and fence connectors will become more readily apparent to those having ordinary skill in the art from the following detailed description taken in conjunction with the accompanying drawings. So that those having ordinary skill in the art to which the present disclosure pertains will more readily understand how to make and use the subject invention, exemplary embodiments thereof will be described in detail herein below with reference to the drawings.
An exemplary material for the construction of the main fence components, including the post, the rails and the bars is aluminum or aluminum alloy but it is also possible to construct these components of steel, stainless steel or iron, if desired.
A fence in accordance with the present disclosure can be constructed from a kit of the various fence components. Although such a kit can include the posts 12, it is also possible for the posts to be purchased or obtained separately. Kits according to the invention can be in various forms and can, for example, comprise the components required to construct one or more of the fence panels 22. In addition to the fence panel components, the kit can also include connecting devices 26 for connecting the fence panel to an adjacent post. A kit for constructing a fence panel can include a plurality of the lower rails 20 and a plurality of the upper rails 18 which may or may not be identical in their construction. By making the upper and lower rails identical one is able to manufacture these rails using the same equipment including, for example, an extrusion die when these rails are made of aluminum or aluminum alloy. The rails can be substantially rectangular in transverse cross section as illustrated in
With respect to the rails shown in
In a first embodiment of the bar or picket 16 for the fence, each bar or picket includes a first bar section 42 and a second bar section 44 each of which is connectable to a respective one of the first bar sections. In the bar 16 illustrated in
When each second bar section 44 is attached to its respective first bar section, they effectively form a bar or picket. In some versions of the fence an additional bar section can also be added to each bar or picket below the lower rail. Each second bar section is mountable on a respective one of the upper rails so as to extend upwardly from a respective one of the bar connecting holes 36 in the upper rail.
A fence panel kit can also include upper connecting devices for connecting upper ends of the first bar sections to their respective upper rails and to the second bar sections as well as lower connecting devices for joining the lower ends of the first bar sections to their respective rails by means of the bar connecting holes formed therein. In the bar or picket of
Each bar or picket 16 can also include a third bar section 60, if desired. Thus the kit for constructing a fence panel can include a plurality of third bar sections for mounting to the lower rail or rails 20 with the third bar sections extending downwardly from the bar connecting holes 36 in their lower rail. When the third bar sections, which can again be solid or hollow, are used, the aforementioned lower connecting devices can comprise threaded integral end sections 62 of the third bar sections together with threaded axial passages 64 formed in lower end sections of the first bar sections. As shown in
As indicated, it is possible to construct a fence panel with a kit according to the present invention without the use of third bar sections. In this alternative version, the lower connecting devices are bolts 70 where each bolt 70 extends through one of the bar connecting holes 36 in the lower rail. Thus, when the fence or barrier panel is assembled, each bolt extends into the threaded axial passage 64 in the lower end section of a respective one of the first bar sections. If desired the head of the bolt 70 can fit wholly or partially into an annular recess 72 formed around the bottom end of its respective hole 36. In this way the bolts are less visible particularly when viewing the fence from normal eye level.
If desired the upper end of the second bar section can be tapered to form a point at 75. This is a well known feature of picket fences and makes it more difficult for a possible intruder to climb over the fence. If desired, a decorative annular disk 76 can be mounted on the second bar section, for example near the centre of its length.
Prior to mounting the second bar section on the upper rail a flexible clip 104 is inserted into the axial passage 98. The clip as illustrated is in the form of an elongate U-shaped member made of a suitably flexible metal or plastic. When the second bar section is upright with the clip therein, two parallel legs 106 of the clip extend downwardly and near each of their bottom ends is an engagement member or bump 108. Although there are two engagement members shown, the clip can have only one engagement member or the clip could be formed with several legs and several engagement members. The engagement members project into respective side apertures 110 formed in the bottom end section 102 and thus hold the clip in its working position. In order to insert the second bar section into its respective first bar section it is first necessary to push inwardly on the engagement members so that they will not interfere with the insertion of the bottom portion of the second bar section into the hole 94 and into the upper end of the first bar section. Additional side apertures 112 are formed in the upper end section of the first bar section and when the second bar section is fully inserted into the hole in the upper rail the two engagement members 108 will extend outwardly into these apertures, thereby holding the two bar sections in locking engagement. It may be necessary to rotate the second bar section about its central axis in order to position the engagement members so that they are aligned with the apertures 112.
It will be appreciated by those skilled in the art that it is equally possible to arrange the clip 104 in the passage 114 formed in the first bar section and then have the legs of a clip extend upwardly to the two engagement members 108 which will then project through the side apertures of the bar sections when the second bar section is fully inserted. To facilitate this bar construction, the external diameter of the first bar section can be less than the diameter of the second bar section or at least the bottom portion of the second bar section.
In a similar manner a third bar section 60′ can be connected to the bottom end of the first bar section using a further flexible clip 115. Thus in this embodiment the clip 115 provides a lower connecting device for joining the lower end of the first bar section 42′ to the lower rail 84 by means of the bar-connecting holes 92, 94 formed in the lower rail. The third bar section 60′ can be hollow so as to form an axial through passage 118 in which the clip can be inserted prior to mounting the third bar section. A main, lower portion of the third bar section can have a diameter equal to the diameter D of the first bar section. However an upper end section 120 has a reduced diameter to permit this upper end section to be inserted into the bottom end of the first bar section. Engagement members 108 formed on the clip 115 will project through side apertures 122 and 124 formed in the third bar section and in the first bar section respectively. Not only does the clip 115 attach the third bar section to the first bar section so that they are in locking engagement but it also acts to secure these two bar sections to the lower rail.
The reduced diameter end sections of the first and third bar sections can be readily formed using a known swaging process. The side apertures such as apertures 110, 112 for the clip engagement members need not necessarily be located within the upper or the lower rail. Although this location is desirable if access to the engagement members after assembly of the fence panel is not desired, for example to prevent theft or vandalism, it is equally possible to locate the side apertures so that they are outside the rail after assembly of each bar or picket and their connection to the rail. Thus for example the side apertures could be located at positions 130 and 132 indicated in
Turning now to the connecting devices 26 that can be used to attach each fence panel to its respective posts, one form of connecting device 26 is illustrated by
Turning now to the construction of the connecting member or connecting sleeve 136, this member has a central axial passageway 146 extending its entire length. By means of this passageway, the connecting member is adapted to receive the shaft section 138 which can extend into a first portion 148 of the connecting member. Only an end portion 150 of the passageway is threaded in one exemplary embodiment with the remaining portion 148 being unthreaded. The diameter of the passageway 148 is slightly greater than the diameter of the shaft section 138. An exemplary embodiment of the connecting member is formed with two threaded screw holes 152, 154, each of these being provided near a respective end of the connecting member. Each of these screw holes is provided to accommodate a socket screw or set screw 155 used to secure in place either the collar pin 134 or an adapter. The screw 155 extending into the unthreaded portion 148 fixedly secures the collar pin in position when the fence panel has been mounted between its post and is in its proper position. An adapter 160 secures one end of the connecting member 136 to a fence post 12. The adapter has external threads, referred to herein as second thread means 162, for securing the connecting member 136 to the adapter. In other words the internal threads of the connecting member 136 engage the external threads 162 of the second thread means. The adapter has an axial passage 164 that extends through the adapter. The adapter has a first portion 166 which is wider than a second portion 168, on which the second thread means 162 are formed. The illustrated adapter has a wider end 170 which has a curved contour matching that of the post 12 to which the adapter is to be attached. If a threaded fastener is to be used to connect the adapter to the post the axial passage 164 is threaded.
The connecting device also has an adapter 194 for securing one end of the connecting member to the post 172. The adapter has thread means 196 for securing the connecting member 184 to the adapter, these threads being sized to engage the threads 188. The adapter 194 also has an axial passage extending the length of the adapter, this passage having a relatively wide section 198, and a relatively narrow section 200 with a tapered shoulder being formed between these two sections. The adapter can be connected to the post by means of a rivet nut 202 which itself is of standard construction and a suitable bolt 204 with its tapered head located in the passageway of the adapter. A hole is formed in the side of the post to receive the rivet nut. An exemplary form of the collar pin 174 is provided with a set screw 206 which can be used to secure the collar pin in its correct position on the fence bar or picket. The illustrated set screw extends through a small axial passage formed in the end of the collar pin. This passage can also be formed in one side of the collar pin so long as it opens into the aperture 183.
