Description

FIELD OF THE INVENTION

The present invention relates to the field of construction material and is particularly concerned with a flexible runner used in the construction of partition walls.

BACKGROUND OF THE INVENTION

The construction of the framing of partition walls has traditionally been carried out according to the following sequence: a first piece of lumber (usually a 2″×4″ lumber) to be used as a floor runner is secured to the floor where the interior wall is to be erected, a second piece of lumber (also a 2″×4″ lumber) to be used as a ceiling runner is secured to the ceiling directly above the first piece of lumber, a plurality of studs are erected between the first and second pieces of lumber, the studs are carefully aligned with the runners and secured thereto via nails while retaining their alignment with the runners.

One major drawback of the above described use of pieces of lumber as floor and ceiling runners is the time consuming step of aligning the studs with the runner and the relative difficulty of keeping that alignment during the securing step.

To avoid the above mentioned drawback, it has been proposed to replace the floor and ceiling lumber runners by U-shaped channels made of galvanised steel. These U-shaped runners are sized to receive conventional wood studs or to receive metallic studs.

Even though the above mentioned use of U-shaped channels as floor and ceiling runners speed up the erection of interior wall frames, a major drawback remains: the U-shaped channel runners are not suited to construct walls presenting a laterally curved portion, walls erected in a space where the distance between a floor and a ceiling varies or half walls having a figured upper end.

DETAILED DESCRIPTION

Referring to FIG. 6 , there is shown a pair of runners 10 both in accordance with an embodiment of the present invention being used for aligning a set of studs 12 . Each stud 12 has a generally elongated configuration defining a pair of longitudinally opposed stud end portions 14 .

It should be understood that the runner 10 could be used for aligning studs 12 having any suitable configuration such as the generally “U”-shaped cross-sectional configuration illustrated in FIG. 6 , a generally rectangular configuration or any other suitable configuration without departing from the scope of the present invention.

Each runner 10 includes at least two stud receiving components 16 .

Typically, each runner 10 includes a plurality of adjacent stud receiving components 16 . Each stud receiving component 16 is configured and sized for receiving a corresponding stud end portion 14 .

Each stud receiving component 16 is provided with a linking means for mechanically linking with an adjacent stud receiving component while allowing the linked stud receiving components to be angled relatively to each other.

Each stud receiving component 16 preferably has a generally concave configuration. In the embodiment illustrated in FIGS. 1 through 7 , each stud receiving component 16 has a generally “U”-shaped cross-sectional configuration defining a base wall 20 having a peripheral edge.

Each stud receiving component 16 also has a pair of retaining flanges 22 extending substantially perpendicularly from opposite sides of the peripheral edge of the base wall 20 .

Typically, the base wall 20 has a generally rectangular and flat configuration defining a pair of opposed longitudinal edges 24 and a pair of perpendicularly oriented transversal edges 26 . The retaining flanges 22 preferably extend integrally from the transversal edges 26 .

Each retaining flange 22 has a proximal edge 28 merging with a transversal edge 26 , an opposed distal edge 30 and a pair of side edges 32 extending between the proximal edge 28 and the distal edge 30 . In a preferred embodiment, each side edge 32 defines a side edge perpendicular segment 34 and an integrally extending side edge angled segment 36 .

Each side edge perpendicular segment 34 extends substantially perpendicularly from the base wall 20 while each side edge angled segment 36 extends at an angle from the adjacent side edge perpendicular segment 34 inwardly towards an opposed side edge angled segment 36 part of the same retaining flange 22 .

In the preferred embodiment, the linking means 18 includes a membrane 38 extending between adjacent stud receiving component 16 . Preferably the membrane 38 is divided into a set of independent strips. Typically, the set of independent strips includes a base strip 40 extending between adjacent base walls 20 and a pair of flange strips 42 extending between the retaining flanges 22 part of adjacent stud receiving components 16 . Preferably, the base strips 40 extend between the longitudinal edges 24 of adjacent base walls 20 while the flange strips 42 extend between the side edge perpendicular segments 34 adjacent the side edge angled segments 36 of adjacent retaining flanges 22 .

The base strip 40 and the flange strips 42 are configured, sized and made out of a suitable material so as to allow bending thereof. Preferably, the suitable material, the size and the configuration given to the strips 40 and 42 is such that a predetermined force is necessary for modifying the configuration of the membrane 38 .

In other words, the configuration and the size of the membrane 38 is customized for a given type of material so that a predetermined force is required for changing the positioning of the stud receiving components 16 relatively to each other.

This feature allows an intended user to give the runner 10 a predetermined configuration by exerting a predetermined force and ensures that the runner 10 will remain substantially in the predetermined configuration. The feature is particularly useful since it allows the runner 10 to be given a predetermined configuration while ensuring that the runner 10 will remain in the predetermined configuration during the following steps leading to the erection of a partition wall such as during the manipulation required for securing the stud end portions 14 in the stud receiving components 16 .

In a preferred embodiment, the base strips 40 and the flange strips 42 are made of a generally rectangular configuration that is inwardly bent about a fold line 44 so as to define a generally “V” shaped cross sectional configuration.

As illustrated in FIG. 6 , at least some of the retaining flanges 22 may be provided with a fixing aperture 54 extending therethrough. The fixing apertures 54 are configured and sized for allowing insertion therein of conventional fastening components such as screws, nails, bolts or the like. Such conventional fastening components may be used for insertion through both the retaining flanges 22 and the studs 12 so as to further secure the studs 12 in the stud receiving components 16 .

Each base strip 40 and each flange strip 42 preferably has a thickness substantially in the range of {fraction (1/16)}″, a width substantially in the range of ¾″, a length substantially in the range of 1″ and is made of galvanized steel, aluminum or the like.

Each runner 10 is preferably integrally formed of a strip of precut and folded material, it would be within the reach of one skilled in the art to design a similar runner wherein the stud receiving components 16 and the linking means are formed independently and assembled together using a conventional method such as spot welding or the like.

A blank 56 used for forming two contiguous stud receiving components 16 part of a runner 10 is illustrated prior to folding in FIG. 5 . The blank 56 includes a flat sheet of material having a generally rectangular configuration and divided into a pair of symmetrical half sections by a central longitudinal fold line 58 corresponding to the fold line 44 .

A lateral longitudinal fold line 60 corresponding to the side edge perpendicular segment 34 extends in a parallel and substantially contiguous relationship to the central longitudinal fold line 58 on each side of the latter. The area delimited by the lateral longitudinal fold lines 60 is provided with a pair of rectangular apertures 62 extending therethrough in a symmetrically spaced relationship relative to each other. The longitudinal edges of the rectangular apertures are in register with the lateral longitudinal fold lines 60 .

A transversal fold line 64 corresponding to the transversal edges 26 extends transversally across the blank intercepting the rectangular apertures 62 . Each transversal peripheral edge of the blank defines a recess 66 delimited by the lateral longitudinal fold lines 60 .

The runner 10 is adapted to be used in either a relatively straight configuration as illustrated in FIGS. 1 and 4 or in one of a multitude of bent configurations some of which are given as examples in FIGS. 2 , 3 , 6 and 7 .

When the runner 10 is in a relatively straight configuration, as illustrated in FIG. 1 , the stud receiving components 16 are aligned so as to form a generally rectilinear runner longitudinal axis 46 .

When a curved wall frame needs to be erected, the runner 10 may be laterally bent so that the stud receiving components 16 define a generally laterally bent runner longitudinal axis 48 as illustrated in FIG. 2 . In order to bend the runner 10 laterally, an intended user merely needs to bring the side edges 32 of adjacent stud receiving components 16 positioned inwardly relatively to the radius of curvature in a relatively proximal relationship relatively to one another while spacing the side edges 32 of adjacent stud receiving components 16 positioned outwardly relatively to the center of the radius of curvature.

The inwardly positioned side edges 32 may be brought in a proximal relationship relatively to one another by squeezing the corresponding flange strips 42 . This operation can be easily performed using a set of conventional pliers 50 as illustrated in FIG. 2 .

When the upper or lower peripheral edge of a wall needs to be given a generally arcuate configuration in a planar direction, the stud receiving components 16 may be positioned so as to define a generally planarly bent runner longitudinal axis 52 as illustrated in FIG. 3 . The planarly bent configuration is particularly suitable in situations wherein the distance between floor and ceiling varies. The planarly bent configuration may also be useful in a variety of other situations such as when the runner 10 is planarly bent about 360 degrees so as to form the framing of an arcuately shaped window opening, columns or the like.

In order to form the configurations illustrated in FIGS. 3 and 7 , an intended user merely needs to bend the runner 10 so that the peripheral edges of adjacent base walls 20 are brought in a proximal relationship relatively to one another. The base strips 40 are thus bent while the specific configuration of the flange strips 40 allow for the bending action of the base strips 40 . In this configuration, the flange strip half sections part of the inwardly positioned flange strips are brought in proximal relationship relatively to one another while the outwardly positioned flange strips 42 are opened up so that the respective flange strip half sections are spaced apart relatively to one another.

It should be understood that the runner 10 could be given any suitable configuration by changing the angular relationship between adjacent stud receiving components 16 . For example, FIG. 6 illustrates the situation wherein the upper and lower runners 10 are both laterally and planarly bent.

The specific configuration of the preferred embodiment of the stud receiving components 16 is adapted to facilitate the alignment of a pair of runners 10 and 101 used jointly to build a given wall structure. It is thus possible to create a floor runner having a configuration substantially identical to a corresponding ceiling runner. In order to ensure that both the runners 10 and 10 ′ have substantially identical configurations, an intended user first configures one of the runners according to a predetermined pattern.

The runner 10 is then used as a guide for configuring the second runner 10 ′. The retaining flanges 22 of the second runner 10 ′ are squeezed inwardly so that the second runner 10 ′ may be partially inserted within the concavities formed by the first runner 10 as illustrated in FIGS. 4 and 7 . The intersections of the retaining flanges with the side edge angled segment 36 forms a guiding and obstructing structure against which abutment will occur. The specific configuration of the preferred embodiment of the side edges 32 thus provides for an abutment means that is used for matingly configuring a pair of jointly working runners 10 and 10 ′.
