Definitions
- the present inventions relate generally to dispensers for support straps and to holsters for such support strap dispensers.
- Support straps are commonly used to secure mechanical and electrical building components, such as plumbing pipes, conduit, heating and air conditioning ducts, and water heaters, to building support structures or to suspend these components from building support structures.
- a flexible strip of material such as sheet metal (e.g., a 24 or 28 gauge strip of copper-plated steel or galvanized steel) or polypropylene, is attached at one end to a support member such as a beam, post, or wall stud.
- the other end of the strip is wrapped around the pipe or conduit and attached in some manner to the first end, thereby forming a loop which supports the conduit.
- Support straps will often include regularly spaced holes along the length of the strap, and some support straps include fasteners to facilitate the connection of one portion of the strap to another after the formation of the loop.
- Support straps are commonly distributed in roll form.
- the length of the support strap in the roll is such that many individual straps will be cut from the roll. The installer will unroll a portion of the strap and remove it from the remainder with a metal cutting tool. Exemplary roll lengths include, but are not limited to, 10 feet, 25 feet and 50 feet.
- the support strap rolls are commonly held with one hand and cut with a tool held in the other hand during the unrolling and cutting process.
- the support strap rolls are also commonly stored within tool boxes or the like during periods of non-use.
- the present inventor has determined that conventional usage and storage methodologies associated with support strap rolls are susceptible to improvement. For example, the resiliency of the rolled support strap can cause the support strap to move as the user is trying to cut it.
- the thin metal material that forms the support strap may also have sharp side edges that can injure the user.
- the support strap roll may also unwind or be otherwise disfigured, and/or the support strap may be bent, when stored in a tool box.
- the present inventor has also determined that it would desirable for a user to be able to remove support strap from a support strap dispenser without having to hold the support strap dispenser with one of his/her hands.
- a support strap dispenser in accordance with at least one of the present inventions includes a housing with an internal storage region and an outlet, and an apparatus, associated with housing, that is configured to frictionally engage the support strap to prevent unwanted movement of the support strap.
- the present inventions also include an assembly which has such a support strap dispenser and a support strap roll located therein.
- the present inventions also include methods of dispensing a support that include the steps of storing the support strap in rolled and frictionally engaging the support strap to prevent movement of the support strap relative to the outlet absent user-applied force.
- a holster for use with a support strap dispenser, in accordance with at least one of the present inventions includes a plurality of walls that define a storage region for the support strap dispenser and at least one outlet opening, which the dispenser outlet will be aligned with when the dispenser is in the storage region, and a retainer that maintains the dispenser in the storage region.
- a system in accordance with at least one of the present inventions includes a support strap dispenser including a housing with an internal storage region configured to store a support strap roll and a dispenser outlet, and a holster including a plurality of walls that define a storage region for the support strap dispenser and at least one outlet opening, which the dispenser outlet will be aligned with when the support strap dispenser is in the storage region, and a retainer that maintains the support strap dispenser in the storage region.

- the present inventions include, but are not limited to, support strap dispensers, dispenser holsters and systems including support strap dispensers and dispenser holsters. Exemplary dispensers are discussed below with reference to FIGS. 1-16 and 21 , exemplary holsters are discussed below with reference to FIGS. 17-20 , and exemplary systems are discussed below with reference to FIGS. 22-27 .
- the support strap dispenser 100 includes a housing 102 having end walls 104 and 106 and a side wall 108 therebetween.
- the housing 102 defines an interior storage region 110 , in which a support strap roll can be stored and protected from damage, and an outlet 112 through which portions of the support strap may be pulled.
- the housing 102 may be provided with a flat surface 114 that allows the strap dispenser 100 to rest in an upright position on a floor, table or other flat support surface.
- Apertures 116 and 118 which extend through end walls 104 and 106 , perform a number of functions. For example, the apertures 116 and 118 form a handle through which the user can place his fingers, with the thumb in the indentation 120 , during use.
- Holding the strap dispenser 100 reduces the likelihood that an edge of the support strap will injure the user, and also allows the other hand to hold a cutting tool.
- the apertures 116 and 118 also define windows that allow the user to see how much of the support strap roll (not shown here) remains within the support strap dispenser 100 .
- a support member 122 which extends from end wall 104 to end wall 106 , provides structural support to maintain the spacing between the walls and, in some instances, defines an axle for the support strap roll.
- Each wall 104 and 106 may also be provided with reinforcing members 124 that augment the structural integrity of the wall. The reinforcing members 124 may be located on the exterior surface (as shown), the interior surface, or both.
- the housing may also include aperture 125 for a D-ring or other structure that allows the support strap dispenser 100 to be connected to a tool belt or the like.
- the exemplary housing 102 illustrated in FIGS. 1 and 2 is generally disc-shaped. One end of the exemplary housing 102 has the flat surface 114 , and the other end of the housing includes the outlet 112 and a dispenser head 126 .
- the user pulls portions of the support strap stored within the dispenser 100 through the outlet 112 prior to cutting off the desired length of support strap.
- the dispenser head 126 fixes the position of the support strap when the support strap is not being pulled, thereby preventing inward and outward movement of the support strap.
- the exemplary housing 102 is defined by a pair of housing members 102 a and 102 b .
- the housing members 102 a and 102 b may, in some instances, be partially or fully separable from one another in order to facilitate placement of the support strap roll into the storage region 110 .
- the housing members 102 a and 102 b respectively include one of the end walls 104 and 106 , and portions 108 a and 108 b of the side wall 108 . In the illustrated implementation, the housing members 102 a and 102 b pivot relative to one another.
- a hinge about which the housing members 102 a and 102 b pivot is located adjacent to the flat surface 114 , and a latch mechanism that locks the housing members 102 a and 102 b in the closed state illustrated in FIGS. 1 and 2 is located on the dispenser head 126 .
- the respective locations of the hinge and latch which are discussed in greater detail below with reference to FIGS. 3-6 , may vary in other implementations.
- the housing members 102 a and 102 b each include a portion of the hinge.
- the housing member 102 a includes a pair of arms 128 that have a wall 130 which defines an indentation 132 .
- the housing member 102 b has a corresponding pair of pins 134 .
- the respective sizes and locations of the arms 128 and pins 134 are such that, when the housing members 102 a and 102 b are brought together, the arms will deflect slightly and the pins will snap into the semi-circular portion of the indentation 132 .
- the housing member 102 b is also provided with clearance slots 136 that the arms 128 move in to as the housing member 102 a pivots away for the orientation illustrated in FIGS. 1 and 2 to the open position.
- the exemplary support strap dispenser 100 is also configured to automatically lock when the housing members 102 a and 102 b pivot from the open position to the orientation illustrated in FIGS. 1 and 2 .
- the exemplary latch includes latch member 138 that cooperates with a latch surface 140 .
- the latch member 138 which is carried by the housing member 102 b in the illustrated embodiment, has a deflectable beam 142 and a projection 144 with a cam surface 146 .
- the projection 144 may extend laterally over a portion of the width of the beam 142 (as shown) or all the way across the beam.
- the latch surface 140 is formed on the housing member 102 b adjacent to the indentation 120 .
- the housing member 102 b is also provided with a slot 148 .
- the cam surface 146 will engage the edge 150 of the slot, thereby deflecting the beam 142 .
- the projection 144 will then slide along the surface of the slot 148 , as the beam 142 remains deflected, until the projection 144 reaches the edge 152 of the slot 148 .
- the resilience of the beam 142 will then cause the flat surface 154 on the projection 144 to engage the latch surface 140 .
- the stiffness of the beam 140 will maintain the latch in the latched state until the beam is deflected (upwardly in the illustrated orientation) to such an extent the flat surface 154 on the projection 144 is free of the latch surface 140 . This may be accomplished by, for example, placing a thumb in the recess 120 and then pushing the latch member 138 . The housing members 102 a and 102 b can then be separated by pivoting them about the aforementioned hinge.
- the present dispensers are not limited to any particular hinge or latch arrangement.
- the hinge may be omitted and two separable housing members may be provided that can be attached and detached as necessary.
- housing portion 102 a includes a pair of posts 156 with pin receptacles 158 and housing portion 102 b includes a pair of posts 160 with pins 162 .
- the posts 156 and 160 are sized and positioned such that the pins 162 will be located within the pin receptacles 158 when the housing 102 is in the closed state illustrated in FIGS. 1 and 2 .
- the support member 122 is defined by a pair of support member portions 122 a and 122 b that abut one another when the housing 102 is in the closed state. The number and location of such alignment and support features may differ in other implementations.
- the exemplary dispenser head 126 includes an upper guide (or “first guide”) 166 , a lower guide (or “second guide”) 168 and a gap 170 therebetween.
- the housing portions 102 a and 102 b include identical mirror image portions of the upper guide 166 , lower guide 168 and gap 170 , and the discussion below is applicable to both housing portions.
- the support strap passes through the gap 170 on its way to the outlet 112 , and the frictional forces between the support strap and portions of the upper guide 166 and lower guide 168 prevent unwanted movement of the support strap relative to the dispenser head 126 .
- the upper guide 166 , lower guide 168 and gap 170 in the illustrated implementation undulate over their respective lengths.
- the upper guide 166 includes a surface with a convex region 172 , a concave region 174 and an apex 176 between the two.
- the side wall inner surface 164 and the upper guide convex region 172 together define a smooth, continuous surface.
- the apex 176 applies a friction-generating force to the support strap that bends the support strap.
- the lower guide 168 includes an end 178 , which defines the pickup (or entry) point where the support strap enters the dispenser head 126 as well as a convex region 180 and a concave region 182 .
- the lower guide end 178 also applies a friction-generating force to the support strap.
- the lower guide 168 may also have a recess 184 that accommodates protrusions that may be found on some support straps (e.g., the support strap illustrated in U.S. Pat. No. 5,522,571 and sold under the trade name TAB TAPE®).
- the exemplary lower guide 168 has a pair of spaced guide surfaces (or rails) 186 that are separated by the recess 184 .
- the materials and size of the dispenser 100 will depend on the intended usage. Suitable materials include, but are not limited to, thermoplastic polymers such as polypropylene.
- a dispenser 100 that is configured for 26-28 gauge support strap rolls that range from 10 to 25 feet in length (unrolled) may be about 5 to 6 inches in height and width. The thickness will depend on the width of the intended support strap.
- FIGS. 9 and 10 show the exemplary support strap dispenser 100 with a rolled support strap 200 carried therein.
- the exemplary support strap 200 includes a main body 202 and a plurality of apertures 204 .
- the main body 202 has a top surface 206 , a bottom surface 208 and side edges 210 and 212 .
- Suitable support strap materials include, but are not limited to, copper, galvanized steel and polypropylene, that is about 0.75 to 1.5 inch wide and about 0.016 inch to about 0.013 inch thick (i.e. about 26-28 gauge).
- the support strap 200 is wound into a spiral roll, with the radially outermost portion 200 a entering the dispenser head 126 by way of the gap 170 .
- the support strap 200 defines a first curvature.
- the magnitude of the first curvature may vary over the length of the support strap and may even be zero (i.e. support strap 200 may be straight) just prior to entering the gap 170 at the lower guide end 178 .
- the lower guide end 178 and support strap portion 200 b engage one another with enough force, in a direction generally perpendicular to support strap portion 200 b , to bend the support strap 200 at the point of engagement into a second curvature.
- the upper guide apex 176 and support strap portion 200 c engage one another with enough force, in a direction generally perpendicular to strap portion 200 c , to bend the support strap 200 at the point of engagement into a third curvature.
- the second and third curvatures are in different directions in the illustrated embodiment, and may be of the same magnitude or different magnitudes.
- a friction force is created between the upper guide apex 176 and support strap portion 200 c that also resists outward and inward movement of the support strap 200 relative to the dispenser head 126 . It should also be noted that friction force is applied to both the top and bottom surfaces 206 and 208 of the strap main body 202 .
- the combined magnitude of the friction forces between the dispenser head 126 and the support strap 200 is large enough to prevent unwanted movement of the support strap in or out of the dispenser 100 .
- the rolled support strap 200 may, for example, store potential energy that is created when the support strap is rolled, when the support strap is placed into the dispenser 100 , and/or when a portion of the support strap is pulled through the outlet 112 by the user. Absent the friction force, the support strap 200 could move after the user has pulled the desired length support strap through the outlet 112 , released the end of the support strap, and is holding the dispenser 100 with one hand and a cutting tool with the other.
- the overall friction force should not, however, be so high that it precludes the user from pulling the support strap through the outlet 112 .
- the friction force may also be adjusted in a variety of ways.
- the thickness of the gap 170 (or a portion thereof) may be reduced to a thickness substantially equal to the thickness of the support strap 200 , thereby increasing the amount of dispenser head/support strap contact.
- the upper guide 166 and/or the lower guide 168 may also be reconfigured such that the bending of the support strap is more or less severe and/or occurs at additional or fewer points along the support strap.
- the smooth, undulating curvatures of the upper guide 166 and/or the lower guide 168 may be replaced with sharper corners and more abrupt changes in direction. Surface roughening may also be employed.
- friction generating forces may be applied to the side edges 210 and 212 of the support strap 200 to control its position within the dispenser head 126 .
- first and second guides 166 and 168 may be reoriented from their illustrated upper/lower orientation.
- first and second guides would be correspondingly rotated and, therefore, could be referred to as “right” and “left” guides, or simply “side,” guides.
- Support strap dispenser 300 is essentially identical to support strap dispenser 100 in structure, function, materials and operating methodology, and similar elements are represented by similar reference numerals.
- support strap dispenser 300 includes a housing 302 having end walls 304 and 306 and a side wall 308 therebetween.
- the housing 302 defines an interior storage region 310 , in which a support strap roll can be stored and protected from damage, and an outlet 312 through which portions of the support strap may be pulled.
- the housing 302 is also provided with a flat surface 314 that is discussed in greater detail below with reference to FIGS. 14-16 .
- Apertures 316 and 318 which extend through end walls 304 and 306 , form a handle and define windows in the manner described above.

Description
- This application is a continuation of application Ser. No. 14/659,007, filed Mar. 16, 2015, which claims the benefit of U.S. Provisional Application Ser. No. 61/969,116, filed Mar. 22, 2014 and entitled “Support Strap Dispensers And Holsters For Use With Same,” each of which is incorporated herein by reference in its entirety.
- 1. Field
- The present inventions relate generally to dispensers for support straps and to holsters for such support strap dispensers.
- 2. Related Art
- Support straps are commonly used to secure mechanical and electrical building components, such as plumbing pipes, conduit, heating and air conditioning ducts, and water heaters, to building support structures or to suspend these components from building support structures. In the exemplary context of hanger straps (sometimes referred to as “plumber's tape”), a flexible strip of material, such as sheet metal (e.g., a 24 or 28 gauge strip of copper-plated steel or galvanized steel) or polypropylene, is attached at one end to a support member such as a beam, post, or wall stud. The other end of the strip is wrapped around the pipe or conduit and attached in some manner to the first end, thereby forming a loop which supports the conduit. Support straps will often include regularly spaced holes along the length of the strap, and some support straps include fasteners to facilitate the connection of one portion of the strap to another after the formation of the loop.
- Support straps are commonly distributed in roll form. The length of the support strap in the roll is such that many individual straps will be cut from the roll. The installer will unroll a portion of the strap and remove it from the remainder with a metal cutting tool. Exemplary roll lengths include, but are not limited to, 10 feet, 25 feet and 50 feet. The support strap rolls are commonly held with one hand and cut with a tool held in the other hand during the unrolling and cutting process. The support strap rolls are also commonly stored within tool boxes or the like during periods of non-use. The present inventor has determined that conventional usage and storage methodologies associated with support strap rolls are susceptible to improvement. For example, the resiliency of the rolled support strap can cause the support strap to move as the user is trying to cut it. The thin metal material that forms the support strap may also have sharp side edges that can injure the user. The support strap roll may also unwind or be otherwise disfigured, and/or the support strap may be bent, when stored in a tool box.
- The present inventor has also determined that it would desirable for a user to be able to remove support strap from a support strap dispenser without having to hold the support strap dispenser with one of his/her hands.
- A support strap dispenser in accordance with at least one of the present inventions includes a housing with an internal storage region and an outlet, and an apparatus, associated with housing, that is configured to frictionally engage the support strap to prevent unwanted movement of the support strap. The present inventions also include an assembly which has such a support strap dispenser and a support strap roll located therein. The present inventions also include methods of dispensing a support that include the steps of storing the support strap in rolled and frictionally engaging the support strap to prevent movement of the support strap relative to the outlet absent user-applied force.
- A holster, for use with a support strap dispenser, in accordance with at least one of the present inventions includes a plurality of walls that define a storage region for the support strap dispenser and at least one outlet opening, which the dispenser outlet will be aligned with when the dispenser is in the storage region, and a retainer that maintains the dispenser in the storage region.
- A system in accordance with at least one of the present inventions includes a support strap dispenser including a housing with an internal storage region configured to store a support strap roll and a dispenser outlet, and a holster including a plurality of walls that define a storage region for the support strap dispenser and at least one outlet opening, which the dispenser outlet will be aligned with when the support strap dispenser is in the storage region, and a retainer that maintains the support strap dispenser in the storage region.

This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the inventions.
- The present inventions include, but are not limited to, support strap dispensers, dispenser holsters and systems including support strap dispensers and dispenser holsters. Exemplary dispensers are discussed below with reference to
FIGS. 1-16 and 21 , exemplary holsters are discussed below with reference toFIGS. 17-20 , and exemplary systems are discussed below with reference toFIGS. 22-27 . - As illustrated for example in
FIGS. 1 and 2 , thesupport strap dispenser 100 includes ahousing 102 havingend walls side wall 108 therebetween. Thehousing 102 defines aninterior storage region 110, in which a support strap roll can be stored and protected from damage, and anoutlet 112 through which portions of the support strap may be pulled. Thehousing 102 may be provided with aflat surface 114 that allows thestrap dispenser 100 to rest in an upright position on a floor, table or other flat support surface.Apertures end walls apertures indentation 120, during use. Holding the strap dispenser 100 (with the support strap roll carried therein) reduces the likelihood that an edge of the support strap will injure the user, and also allows the other hand to hold a cutting tool. Theapertures support strap dispenser 100. Asupport member 122, which extends fromend wall 104 to endwall 106, provides structural support to maintain the spacing between the walls and, in some instances, defines an axle for the support strap roll. Eachwall members 124 that augment the structural integrity of the wall. The reinforcingmembers 124 may be located on the exterior surface (as shown), the interior surface, or both. The housing may also includeaperture 125 for a D-ring or other structure that allows thesupport strap dispenser 100 to be connected to a tool belt or the like. - Although the present dispensers are not limited to any particular shape, the
exemplary housing 102 illustrated inFIGS. 1 and 2 is generally disc-shaped. One end of theexemplary housing 102 has theflat surface 114, and the other end of the housing includes theoutlet 112 and adispenser head 126. During use, and as is explained in greater detail below with reference toFIGS. 7-10 , the user pulls portions of the support strap stored within thedispenser 100 through theoutlet 112 prior to cutting off the desired length of support strap. Thedispenser head 126 fixes the position of the support strap when the support strap is not being pulled, thereby preventing inward and outward movement of the support strap. - The
exemplary housing 102 is defined by a pair ofhousing members housing members storage region 110. Thehousing members end walls portions side wall 108. In the illustrated implementation, thehousing members housing members flat surface 114, and a latch mechanism that locks thehousing members FIGS. 1 and 2 is located on thedispenser head 126. The respective locations of the hinge and latch, which are discussed in greater detail below with reference toFIGS. 3-6 , may vary in other implementations. - Turning to
FIGS. 3 and 4 , thehousing members housing member 102 a includes a pair ofarms 128 that have awall 130 which defines anindentation 132. Thehousing member 102 b has a corresponding pair ofpins 134. The respective sizes and locations of thearms 128 and pins 134 are such that, when thehousing members indentation 132. Thehousing member 102 b is also provided withclearance slots 136 that thearms 128 move in to as thehousing member 102 a pivots away for the orientation illustrated inFIGS. 1 and 2 to the open position. - The exemplary
support strap dispenser 100 is also configured to automatically lock when thehousing members FIGS. 1 and 2 . To that end, and referring toFIGS. 5 and 6 , the exemplary latch includeslatch member 138 that cooperates with alatch surface 140. Thelatch member 138, which is carried by thehousing member 102 b in the illustrated embodiment, has a deflectable beam 142 and aprojection 144 with acam surface 146. Theprojection 144 may extend laterally over a portion of the width of the beam 142 (as shown) or all the way across the beam. Thelatch surface 140 is formed on thehousing member 102 b adjacent to theindentation 120. Thehousing member 102 b is also provided with aslot 148. As thehousing members cam surface 146 will engage theedge 150 of the slot, thereby deflecting the beam 142. Theprojection 144 will then slide along the surface of theslot 148, as the beam 142 remains deflected, until theprojection 144 reaches theedge 152 of theslot 148. The resilience of the beam 142 will then cause theflat surface 154 on theprojection 144 to engage thelatch surface 140. - The stiffness of the
beam 140 will maintain the latch in the latched state until the beam is deflected (upwardly in the illustrated orientation) to such an extent theflat surface 154 on theprojection 144 is free of thelatch surface 140. This may be accomplished by, for example, placing a thumb in therecess 120 and then pushing thelatch member 138. Thehousing members - It should be noted here that the present dispensers are not limited to any particular hinge or latch arrangement. For example, the hinge may be omitted and two separable housing members may be provided that can be attached and detached as necessary.
- The
housing 102 may also be provided with various alignment and support features. In the illustrated implementation, and referring toFIGS. 3 and 4 ,housing portion 102 a includes a pair ofposts 156 withpin receptacles 158 andhousing portion 102 b includes a pair ofposts 160 withpins 162. Theposts pins 162 will be located within thepin receptacles 158 when thehousing 102 is in the closed state illustrated inFIGS. 1 and 2 . Thesupport member 122 is defined by a pair ofsupport member portions housing 102 is in the closed state. The number and location of such alignment and support features may differ in other implementations. - When a support strap roll is placed into the
storage region 110, the outer portion of the roll will be located radially inward of theposts dispenser head 126. In many instances, the portion of the support strap roll that is approaching the dispenser head will rest against the inner surface 164 (FIG. 3 ) of theside wall 108. - Turning to
FIGS. 7 and 8 , theexemplary dispenser head 126 includes an upper guide (or “first guide”) 166, a lower guide (or “second guide”) 168 and agap 170 therebetween. Thehousing portions upper guide 166,lower guide 168 andgap 170, and the discussion below is applicable to both housing portions. The support strap passes through thegap 170 on its way to theoutlet 112, and the frictional forces between the support strap and portions of theupper guide 166 andlower guide 168 prevent unwanted movement of the support strap relative to thedispenser head 126. Theupper guide 166,lower guide 168 andgap 170 in the illustrated implementation undulate over their respective lengths. In particular, theupper guide 166 includes a surface with aconvex region 172, aconcave region 174 and an apex 176 between the two. In the illustrated embodiment, the side wallinner surface 164 and the upper guideconvex region 172 together define a smooth, continuous surface. As discussed below with reference toFIG. 9 , the apex 176 applies a friction-generating force to the support strap that bends the support strap. Thelower guide 168 includes anend 178, which defines the pickup (or entry) point where the support strap enters thedispenser head 126 as well as aconvex region 180 and aconcave region 182. Thelower guide end 178 also applies a friction-generating force to the support strap. - In some implementations, including the illustrated implementation, the
lower guide 168 may also have arecess 184 that accommodates protrusions that may be found on some support straps (e.g., the support strap illustrated in U.S. Pat. No. 5,522,571 and sold under the trade name TAB TAPE®). As a result, the exemplarylower guide 168 has a pair of spaced guide surfaces (or rails) 186 that are separated by therecess 184. - The materials and size of the
dispenser 100 will depend on the intended usage. Suitable materials include, but are not limited to, thermoplastic polymers such as polypropylene. Adispenser 100 that is configured for 26-28 gauge support strap rolls that range from 10 to 25 feet in length (unrolled) may be about 5 to 6 inches in height and width. The thickness will depend on the width of the intended support strap. -
FIGS. 9 and 10 show the exemplarysupport strap dispenser 100 with a rolledsupport strap 200 carried therein. Although the present inventions are not limited to any particular support straps, theexemplary support strap 200 includes amain body 202 and a plurality ofapertures 204. Themain body 202 has atop surface 206, abottom surface 208 andside edges - The
support strap 200 is wound into a spiral roll, with the radiallyoutermost portion 200 a entering thedispenser head 126 by way of thegap 170. As a result of being wound into a spiral roll, thesupport strap 200 defines a first curvature. The magnitude of the first curvature may vary over the length of the support strap and may even be zero (i.e.support strap 200 may be straight) just prior to entering thegap 170 at thelower guide end 178. Thelower guide end 178 andsupport strap portion 200 b engage one another with enough force, in a direction generally perpendicular to supportstrap portion 200 b, to bend thesupport strap 200 at the point of engagement into a second curvature. As a result, there is a friction force between thelower guide end 178 andsupport strap portion 200 b that resists outward and inward movement (note arrows A and B) of thesupport strap 200 relative to thedispenser head 126. The relative thicknesses of thegap 170 andsupport strap 200, and the undulating shape of theupper guide 166 and thelower guide 168, results in the support strap being spaced apart from (and out of contact with) the upper guide and the lower guide between theupper guide apex 176 and thelower guide end 178. Theupper guide apex 176 andsupport strap portion 200 c engage one another with enough force, in a direction generally perpendicular tostrap portion 200 c, to bend thesupport strap 200 at the point of engagement into a third curvature. The second and third curvatures are in different directions in the illustrated embodiment, and may be of the same magnitude or different magnitudes. A friction force is created between theupper guide apex 176 andsupport strap portion 200 c that also resists outward and inward movement of thesupport strap 200 relative to thedispenser head 126. It should also be noted that friction force is applied to both the top andbottom surfaces main body 202. - The combined magnitude of the friction forces between the
dispenser head 126 and thesupport strap 200 is large enough to prevent unwanted movement of the support strap in or out of thedispenser 100. The rolledsupport strap 200 may, for example, store potential energy that is created when the support strap is rolled, when the support strap is placed into thedispenser 100, and/or when a portion of the support strap is pulled through theoutlet 112 by the user. Absent the friction force, thesupport strap 200 could move after the user has pulled the desired length support strap through theoutlet 112, released the end of the support strap, and is holding thedispenser 100 with one hand and a cutting tool with the other. The overall friction force should not, however, be so high that it precludes the user from pulling the support strap through theoutlet 112. - The friction force may also be adjusted in a variety of ways. For example, the thickness of the gap 170 (or a portion thereof) may be reduced to a thickness substantially equal to the thickness of the
support strap 200, thereby increasing the amount of dispenser head/support strap contact. Theupper guide 166 and/or thelower guide 168 may also be reconfigured such that the bending of the support strap is more or less severe and/or occurs at additional or fewer points along the support strap. The smooth, undulating curvatures of theupper guide 166 and/or thelower guide 168 may be replaced with sharper corners and more abrupt changes in direction. Surface roughening may also be employed. Additionally, or alternatively, friction generating forces may be applied to the side edges 210 and 212 of thesupport strap 200 to control its position within thedispenser head 126. - It should also be noted that the first and
second guides support strap 200 within thedispenser head 126 is rotated to some extent from its illustrated orientation (e.g., ninety degrees) about its longitudinal axis. Here, the first and second guides would be correspondingly rotated and, therefore, could be referred to as “right” and “left” guides, or simply “side,” guides. - Another exemplary support strap dispenser is generally represented by
reference numeral 300 inFIG. 11 .Support strap dispenser 300 is essentially identical to supportstrap dispenser 100 in structure, function, materials and operating methodology, and similar elements are represented by similar reference numerals. For example,support strap dispenser 300 includes ahousing 302 havingend walls side wall 308 therebetween. Thehousing 302 defines aninterior storage region 310, in which a support strap roll can be stored and protected from damage, and anoutlet 312 through which portions of the support strap may be pulled. Thehousing 302 is also provided with aflat surface 314 that is discussed in greater detail below with reference toFIGS. 14-16 .Apertures end walls support member 322 is also provided, as are reinforcingmembers 324 on eachwall - The
exemplary housing 302 is defined by a pair ofhousing members FIGS. 14-16 ). A latch mechanism, includingexemplary latch member 338, that locks thehousing members FIGS. 11 and 12 may be located on thedispenser head 326. The location of thelatch member 338 is offset from the location oflatch member 128 indispenser 100. - Turning to
FIGS. 12 and 13 , the exemplarysupport strap dispenser 300 also includes adispenser head 326 that fixes the position of the support strap when the support strap is not being pulled by the user, thereby preventing inward and outward movement of the support strap. Like thedispenser head 126, thedispenser head 326 includes an upper guide (or “first guide”) 366, a lower guide (or “second guide”) 368 and agap 370 therebetween, each of which undulate over their respective lengths. The support strap passes through thegap 370 on its way to theoutlet 312, and the frictional forces between the support strap and portions of theupper guide 366 andlower guide 368 prevent unwanted movement of the support strap relative to thedispenser head 326 in the manner described above. Thelower guide 368 in the illustrated implementation also has arecess 384 that accommodates protrusions that may be found on some support straps and a pair of spaced guide surfaces (or rails) 386 that are separated by therecess 384. Here, however, a plurality oftriangular structures 385 are located within therecess 384 and are longitudinally spaced along the gap 380. Thetriangular structures 385 facilitate loading the support strap (e.g.,support strap 200 inFIGS. 9 and 10 ) into thedispenser 300. In particular, thetriangular structures 385 guide one of the support strap side edges (e.g.,side edge 210 or 212) onto one of the guide surfaces 386 as the support strap placed into one of thehousing members dispenser 300 is in an open, and guide the other support strap side edge onto the other guide surface as the housing members are brought together to close the dispenser. - As illustrated for example in
FIGS. 14-16 , the housingflat surface 314 is formed fromflat portions housing members flat portion protrusions 315 that support thedispenser 300 when it is placed in an upright position on a floor, table or other flat support surface. Theflat portions housing members housing members flat portions - One example of a holster for a support strap dispenser is generally represented by
reference numeral 400 inFIGS. 17-20 . Theexemplary holster 400 includes front andrear walls side walls bottom wall 408. The walls 402-408 together define adispenser storage region 410, a dispenser insertion/removal opening 412, and a pair ofoutlet openings outlet openings storage region 410. Theoutlet openings front wall 402 also has anedge 424 that aligns with the dispenser aperture when the dispenser in thestorage region 410, as is discussed below with reference toFIG. 22 , while therear wall 404 has curvedupper edges - The
exemplary holster 400 illustrated inFIGS. 17-20 may also include one or more retainer mechanisms that hold the dispenser in thestorage region 410. In the illustrated implementation,movable tabs side walls FIGS. 17-20 . Thetabs side walls slots exemplary tabs side walls storage region 410, and through the insertion/removal opening 412, by the user in the manner described below with reference toFIG. 22 . - The
exemplary holster 400 illustrated inFIGS. 17-20 may also include one or more retainer mechanisms that mount the dispenser on the user. In the illustrated implementation, theholster 400 includes aresilient clip 432 that may be used to mount the holster on, for example, a belt, tool belt, or a pant waist. Theresilient clip 432 may be formed as an integral part of theholster 400, or formed separately and attached to the holster. - The materials and size of the
holster 400 will depend on the intended usage and the size of the associated dispenser. Suitable materials include, but are not limited to, thermoplastic polymers such as polypropylene. - One example of a support strap dispenser that may be used in conjunction with the
holster 400 is generally represented byreference numeral 300′ inFIG. 21 .Support strap dispenser 300′ is essentially identical to supportstrap dispenser 300 in structure, function, materials and operating methodology, and similar elements are represented by similar reference numerals. For example,support strap dispenser 300′ includes ahousing 302′ that defines aninterior storage region 310, in which a support strap roll can be stored and protected from damage, and anoutlet 312′ through which portions of the support strap may be pulled. Theinterior storage region 310 is visible by way ofapertures outlet 312′ has arecess 384′ that is slightly deeper than recess 384 (FIG. 12 ), and thelatch 338′ is slightly thicker than latch 338 (FIG. 12 ). - Turning to
FIGS. 22 and 23 , asystem 20 in accordance with the present invention includes a dispenser (e.g.,dispenser 300′), with or without a rolled support strap carried therein, and a holster (e.g., holster 400). The exemplarysupport strap dispenser 300′ andholster 400 are respectively sized and shaped such that the dispenser will fit snugly into thestorage region 410 and themovable tabs exemplary system 20, the width WD of thedispenser housing 302′ at its widest point is slightly greater (e.g., about 3-5 mm greater) than the distance DT between the free ends of thetabs dispenser 300′ is pushed into theholster 400 through the insertion/removal opening 412 in the direction of the arrow (or the holster is pushed over the dispenser), the outer surface of the dispenser will push thetabs tabs FIG. 22 as the widest point WP passes the free ends and thedispenser 300′ reaches the fully inserted position illustrated inFIGS. 23-25 . Here, portions of theholster 400 will abut portions of thedispenser 300′ above and below (in the illustrated orientation) the widest point WP, thereby trapping the dispenser in thestorage region 410. The resilience of thetabs dispenser 300′ will not pop out of the holster during normal use, yet will allow the user to easily place the dispenser into theholster 400 and also remove the dispenser therefrom. It should also be noted that the distance between the front andrear walls holster 400 is essentially equal to the thickness of thedispenser 300′ in the illustrated implementation (noteFIGS. 24 and 25 ). - As alluded to above, the respective configurations of the
support strap dispenser 300′ andholster 400 are such that the windows defined by thedispenser apertures front wall edge 424 in the manner illustrated inFIGS. 23-25 when the dispenser is fully inserted into theholster storage region 410. Thedispenser storage region 310 will, therefore, be visible by way of theapertures dispenser 300′ is located within theholster 400. As best seen inFIGS. 24 and 25 , thedispenser outlet 312′ will be aligned with one of theoutlet openings dispenser 300′ is fully inserted into theholster 400. In addition, the positions of the edges 416 a-422 a that define opening 414 a and the positions of theedges 416 b-422 b that define opening 414 b (noteFIGS. 18 and 20 ) in the illustrated implementation are located such that thedispenser outlet 312′ protrudes though the outlet opening that the outlet is aligned with when thedispenser 300′ is fully inserted into theholster 400. - The
holster 400, and/or the associateddispenser 300′, may also be mechanically keyed or otherwise configured to prevent rotation of the dispenser relative to the holster as lengths ofsupport strap 200 are pulled from the dispenser. - In the illustrated implementation, the
holster 400 includes a peg or other projection 434 (FIG. 20 ) on thebottom wall 408 and thedispenser 300′ includes an aperture 388 (FIG. 21 ). Theprojection 434 will enter theaperture 388 when thedispenser 300′ is in the fully inserted position illustrated inFIGS. 23-25 , thereby preventing rotation of the dispenser. Theprojection 434 is also centered on thebottom wall 408 such that it will be aligned with theaperture 388 regardless of the orientation (i.e., theFIG. 26 orientation or theFIG. 27 orientation) of thedispenser 300′. In other implementations, the locations of the projection and the aperture may be reversed, and other anti-rotation keying arrangements may be employed. - Turning to
FIGS. 26 and 27 , the respective configurations of thesupport strap dispenser 300′ and theholster 400 are such that the orientation of the dispenser may be reversed. Theholster 400 is symmetric about its vertical axis VA. Regardless of orientation, thedispenser outlet 312′ will be aligned with one of theoutlet openings dispenser apertures front wall edge 424, and theholster projection 434 will be located in thedispenser aperture 388. Orientation of thedispenser 300′ and theholster 400 relative to one another in the manner illustrated inFIG. 26 facilitates placement of thesystem 20 on, for example, the user's left hip. So positioned, theoutlet 312′ will face forwardly so that the user can conveniently pull strap through the outlet with his/her left hand and cut the strap with a cutting instrument in his/her right hand. Alternatively, when thedispenser 300′ and theholster 400 are oriented relative to one another in the manner illustrated inFIG. 27 , thesystem 20 may be placed on, for example, the user's right hip. So positioned, theoutlet 312′ will face forwardly so that the user can conveniently pull strap through the outlet with his/her right hand and cut the strap with a cutting instrument in his/her left hand. In both of these instances, the mounting of thedispenser 300′ in theholster 400 onto the user (by way of a belt, tool belt, etc.) eliminates need for the user to hold the dispenser with one hand while pulling support strap with the other. - Turning to
FIGS. 28 and 29 , theholster 400′, which is essentially identical to holster 400 in structure, function, materials and operating methodology, may include alatch 436 in place of theprojection 434 inholster 400. Theexemplary latch 436 includes one ormore latch members 438, and there are fourlatch members 438 in the illustrated embodiment. Eachlatch member 438 includes a deflectable (or “pivotable”)post 440 and ahead 442 with first and second cam surfaces 444 a and 444 b. There is also agap 446 between each adjacent pair oflatch members 438, anaperture 448 adjacent to eachlatch member 438 that extends though thebottom wall 408, and acentral aperture 450. - The
holster 400′ may be used in conjunction with asupport strap dispenser 300″ that is essentially identical to supportstrap dispenser 300′ in structure, function, materials and operating methodology. Here, however, the aperture 388 (FIG. 21 ) is replaced by theaperture 388′ illustrated inFIGS. 30 and 31 . Theaperture 388′ includes atapered surface 389 which is configured to interact with the latch member cam surfaces 444 a. - The
holster latch 436 may be secured to thedispenser 300″ as follows. Thedispenser 300″ andholster 400′ will approach one another (FIG. 30 ) until the cam surfaces 444 a engage the taperedsurface 389. Continued movement will cause the latch member posts 440 to deflect inwardly, and out of their rest state, so that the latch member heads 442 can pass through theaperture 388′. The latch member posts 440 will remain in the inwardly deflected state until theheads 442 pass completely through theaperture 388′. At this point, the latch member posts 440 will pivot back to their rest state and the cam surfaces 444 b will rest against aninner surface 303 of thehousing 302′, thereby latching thedispenser 300″ to theholster 400′. This results in a more secure dispenser/holster connection than that associated with theprojection 434. The cam surfaces 444 b will cause the latch member posts 440 to deflect inwardly, thereby releasing thelatch 436, when thedispenser 300′ pulled out of theholster 400′ by the user. - Although the present inventions have been described in terms of the preferred embodiments above, numerous modifications and/or additions to the above-described preferred embodiments would be readily apparent to one skilled in the art. By way of example, but not limitation, the present inventions include assemblies that comprise a support strap dispenser as described above in combination with a support strap roll located in the internal storage region of the support strap dispenser. The dispensers described above may also be used in conjunction with wire, adhesive painter's tape and other dispensable objects that are stored in roll form and, in at least some instances, cut to length as they are consumed. The present inventions also include assemblies that comprise a holster as described above or claimed below in combination with a dispenser that dispenses wire, adhesive painter's tape and other dispensable objects that are stored in roll form and, in at least some instances, cut to length as they are consumed. It is intended that the scope of the present inventions extends to all such modifications and/or additions.
