Description

APPARATUSES, SYSTEMS, AND METHODS OF INSULATION INSTALLATION

CROSS-REFERENCE

[0001] The present disclosure claims the benefit and priority to U.S. Application No. 63/269,176 filed March 11, 2022, which is hereby incorporated by reference.

TECHNICAL FIELD

[0002] The present disclosure relates to insulation installation tools and apparatuses, systems, and methods of insulation installation.

BACKGROUND

[0003] A number of apparatuses, systems, and methods have been proposed for installing insulation. Some proposals involve blowing or flowing loose or particulate insulation into an open wall or ceiling cavity. Such proposals have traditionally used a plastic sheet that is attached to wall framing members to enclose a wall cavity before insulation is installed and which remains in place once insulation installation is complete. Other proposals have sought to use various other barriers in lieu of plastic sheets. Existing proposals suffer from a number of drawbacks, limitations, and shortcomings including those respecting ease of operation, and effective coverage and distribution of insulation, among others. There remains a significant need for the unique apparatuses systems and methods disclosed herein.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

[0031] With reference to Figs. 1-5, there are illustrated several views of an example tool 100 for installing insulation. As shown in Fig. 1, tool 100 may be deployed in an example work environment which includes a wall framing 10 including a ceiling joist 13, an upper horizontal stud 12, a first vertical stud 14, a second vertical stud 16, and a lower horizontal stud 18, among other joists, studs, and framing members (not depicted). The wall framing 10 is disposed on and supported by an underlying floor surface 19. Upper horizontal stud 12, first vertical stud 14, second vertical stud 16, and lower horizontal stud 18 bound a wall frame chamber 21 which is substantially covered by tool 100 in the view of Fig. 1, but is visible in Fig. 6 which illustrates the environment including wall framing 10 in the absence of tool 100. In the view of Fig. 1, tool

100 and framing 10 are illustrated relative to a Cartesian coordinate system with a vertical axis direction indicated by arrow Z-Z and a horizontal axis direction indicated by arrow X-X.

[0032] Tool 100 includes a frame 101 including a first vertical beam 110a and a second vertical beam 110b which extend vertically along a height of the frame 101. Frame 101 further includes a first horizontal beam 120 and a second horizontal beam 122 which extends horizontally along a width of the frame 101. The first and second vertical beams 110a, 110b and the first and second horizontal beams 120, 122 bound an interior frame region 116.

[0033] Frame 101 is further provided with feet 117a, 117b, wheels 119a, 119b, and jack 121. In the state illustrated in Fig. 1, jack 121 has been actuated to a raised position in which frame

101 is raised relative to floor surface 19 and urged into contact with ceiling joist 13. Jack 121 may also be actuated to a lowered position in which frame 101 is lowered and spaced apart from ceiling joist 13 and wheels 119a, 119b are lowered into contact with floor surface 19 to facilitate horizontal movement and repositioning of tool 100 via lateral rolling on wheels 119a, 119b. In the lowered position, feet 117a, 117b are raised slightly above floor surface 19 relative to wheels 119a, 119b to limit the tilting or tipping of tool 100. Jack 121 may be a foot-actuated j ack and may include a hydraulic jack mechanism or various other types of jack or actuator mechanisms as will occur to one of skill in the art with the benefit and insight of the present disclosure.

[0034] In the illustrated example, jack 121 is configured to provide a centrally positioned point of contact between tool 100 and floor surface 19. In some embodiments, may be configured to provide additional or alternative points of contact between tool 100 and floor surface 19. For example, jack 121 may be configured to provide multiple points of contact. In some such forms, jack 121 may include multiple foot-actuated j acks. In some such forms, jack 121 may a single foot-actuated jack with multiple points of contact between tool 100 and floor surface 19.

[0035] In the illustrated example, wheels 119a, 119b are provided as fixed position linear casters which are rotatable to accommodate horizontal motion of the tool 100 in the X-axis direction. In some embodiments, wheels 119a, 119b may be provided as swivel casters, which are rotatable about two axes to accommodate horizontal motion of the tool 100 in the X-axis direction and motion of the tool in the Y-axis direction. When provided as swivel casters, wheels 119a, 119b may be selectably lockable and unlockable to various positions, for example, to accommodate only horizontal motion of the tool 100 in the X-axis direction, accommodate only motion of the tool in the Y-axis direction, and accommodate a combination of horizontal motion of the tool 100 in the X-axis direction and motion of the tool in the Y-axis direction.

[0036] The first vertical beam 110a includes a first lower beam member 114a and a first upper beam member 112a which is extensible and retractable relative to the first lower beam member 114a to vary the height of the first vertical beam 110a. The second vertical beam 110b includes a second lower beam member 114b and a second upper beam member 112b extensible and retractable relative to the second lower beam member 114b to vary the height of the second vertical beam 110b.

[0037] Handles 139a, 139b are coupled with first vertical beam 1 10a and second vertical beam 110b, respectively, and may be grasped by a user of tool 100 to manipulate and reposition tool 100. In the illustrated example, handles 139a, 139b are coupled with and extend from first lower beam member 114a and second lower beam member 114b, respectively. In some embodiments, handles 139a, 139b may be coupled with other structures of frame 101 and may be provided at different positions relative to frame 101. In some embodiments, handles 139a, 139b may be provided in other forms, such as recesses, grips, knobs, or other handle forms as will occur to one of skill in the art with the benefit and insight of the present disclosure.

[0038] In the embodiment of Figs. 1-5, first upper beam member 112a is arranged in a telescoping relationship with first lower beam member 114a such that the overall vertical height of first vertical beam 110a is variable by moving first upper beam member 112a in and out of first lower beam member 114a. A handle 115a may be adjusted by an operator to selectively fix the position of first upper beam member 112a relative to first lower beam member 114a or permit movement of first upper beam member 112a relative to first lower beam member 114a.

[0039] Second upper beam member 112b is arranged in a telescoping relationship with second lower beam member 114b such that the overall vertical height of second vertical beam 110b is variable by moving second upper beam member 112b in and out of second lower beam member 114b. A handle 115b may be adjusted by an operator to selectively fix the position of second upper beam member 112b relative to second lower beam member 114b or permit movement of second upper beam member 112b relative to second lower beam member 114b.

[0040] Other embodiments may include different arrangements of upper beam members relative to lower beam members, for example, sliding ladder-type arrangements (e g., side-by- side, top-to-bottom, or a combination side-by-side and top-to-bottom sliding ladder-type arrangements), partially overlapping arrangements, other types of nested arrangements, or other arrangements as will occur to one of skill in the art with the benefit and insight of the present disclosure. Other embodiments may include fixed-length beam members which may be singlepiece fixed-length beam members or multi-piece fixed-length beam members.

[0041] With continuing reference to Figs. 1-5, a carriage 140 extends horizontally intermediate the first and second vertical beams 110a, 110b and is vertically moveable along at least a portion of the vertical height of the first and second vertical beams 110a, 110b. Carriage 140 includes a receptacle 160 which is configured to receive a nozzle of an insulation blower (not depicted) and defines an aperture providing access to the wall frame chamber 21 underlying the tool 100.

[0042] Carriage 140 includes an upper horizontal carriage beam 143a, a lower horizontal carriage beam 143b, and first and second vertical carriage beams 142a, 142b. Carriage 140 further includes a shuttle 150 in which receptacle 160 is provided. Shuttle 150 is horizontally moveable along at least a portion of a horizontal width of carriage 140.

[0043] A first sheeting 132a extends horizontally in interior frame region 116 intermediate first and second vertical beams 110a, 110b and extends vertically in interior frame region 116 intermediate carriage 140 and first horizontal beam 120. First sheeting 132a is extensible and retractable in response to vertical movement of carriage 140. First sheeting 132a is also extensible and retractable in response to extension and retraction of first upper beam member 112a relative to first lower beam member 114a and second upper beam member 112b relative to second lower beam member 114b.

[0044] A second sheetingl32b extends horizontally in interior frame region 116 intermediate first and second vertical beams 110a, 110b and extends vertically in interior frame region 116 intermediate carriage 140 and second horizontal beam 122. Second sheeting 132b is extensible and retractable in response to vertical movement of carriage 140. Second sheeting 132b is also extensible and retractable in response to extension and retraction of first upper beam member 112a relative to first lower beam member 114a and second upper beam member 112b relative to second lower beam member 114b.

[0045] First sheeting 132a is operatively coupled with a first spool 134a and is extensible and retractable by unwinding and winding about the first spool 134a. In the embodiment of Figs. 1- 5, first spool 134a is disposed within first horizontal beam 120. In other embodiments, first spool 134a may be coupled with first horizontal beam 120 and/or with other structures of frame 101 in other manners. For example, in some embodiments, first spool 134a may be external to and coupled with first horizontal beam 120. In some embodiments, first spool 134a may be disposed within another housing, container, or other structure which is coupled with first horizontal beam 120, coupled with first and second vertical beams 110a, 110b, and/or coupled with other structures of frame 101.

[0046] In some embodiments, first spool 134a may be disposed, in whole or in part, within carriage 140, for example, within upper horizontal carriage beam 143a. In some embodiments, first spool 134a may be external to and coupled with and moveable with carriage 140. In some embodiments, first spool 134a may be disposed within another housing, container, or other structure which is coupled with and moveable with carriage 140. In some embodiments, another type of sheeting uptake mechanism may be utilized in lieu of first spool 134a. Examples of such alternative sheeting uptake mechanisms may include accordion-type tensioners or folding mechanisms, winding or spooling mechanisms, as well as other mechanisms as will occur to one of skill in the art with the benefit and insight of the present disclosure.

[0047] Second sheeting 132b is operatively coupled with a second spool 134b and is extensible and retractable by unwinding and winding about the second spool 134b. In the embodiment of Figs. 1-5, second spool 134b is disposed within second horizontal beam 122. In other embodiments, second spool 134b may be coupled with second horizontal beam 122 and/or with other structures of frame 101 in other manners such as those described elsewhere herein. For example, in some embodiments, second spool 134b may be external to and coupled with second horizontal beam 122. In some embodiments, second spool 134b may be disposed within another housing, container, or other structure which is coupled with second horizontal beam 122, coupled with first and second vertical beams 110a, 110b, and/or coupled with other structures of frame 101.

[0048] In some embodiments, second spool 134b may be disposed, in whole or in part, within carriage 140, for example, within lower horizontal carriage beam 143b. In some embodiments, second spool 134b may be external to and coupled with and moveable with carriage 140. In some embodiments, second spool 134b may be disposed within another housing, container, or other structure which is coupled with and moveable with carriage 140. It is further contemplated that another type of sheeting uptake mechanism, such as the alternatives mechanisms described above, may be utilized in lieu of second spool 134b.

[0049] As shown in the views of Figs. 1 and 5, tool 100 may be positioned so that first sheeting 132a and second sheeting 132b contact wall framing 10 to enclose a wall chamber such as wall chamber 21. In the illustrated example, first sheeting 132a contacts at least a portion of upper horizontal stud 12, first vertical stud 14, and second vertical stud 16, and second sheeting 132b contacts at least a portion of lower horizontal stud 18, first vertical stud 14, and second vertical stud 16. Such overlapping positioning substantially closes an open face of wall chamber 21 with an insulation retaining barrier or shield that is permeable to airflow. This arrangement allows insulation to be blown into and retained within wall chamber 21. Jack 121 is configured to provide a range of actuation that facilitates overlapping contact between first sheeting 132a and second sheeting 132b on the one hand, and wall framing 10 on the other hand. Thus, when actuated, jack 121 may position tool 100 in the position illustrated in Fig. 1 to substantially enclose an open face of wall chamber 21 with an insulation retaining barrier or shield that is permeable to airflow.

[0050] A gasket feature to facilitate seal formation with wall framing 10 may be provided on one or both of first sheeting 132a and second sheeting 132b. A gasket feature to facilitate seal formation with framing 10 may additionally or alternatively be provided on one or more of first vertical beam 110a, second vertical beam 110b, first horizontal beam 120, and second horizontal beam 122 so that seal formation between tool 100 and wall framing 10 may be provided even where a wall framing component extends outside the area of first sheeting 132a or second sheeting 132b. In some forms, the horizontal (X-axis direction) width of tool 100 may be selected to enclose a chamber based on standardized stud spacing, for example, 24 inches center- to-center spacing.

[0051] A third sheeting 145a extends horizontally intermediate a first vertical carriage beam 142a and shuttle 150 and extends vertically intermediate upper horizontal carriage beam 143a and a lower horizontal carriage beam 143b. The third sheeting 145a is extensible and retractable in response to horizontal movement of the shuttle 150.

[0052] A fourth sheeting 145b extends horizontally intermediate a second vertical carriage beam 142b and shuttle 150 and extends vertically intermediate upper horizontal carriage beam 143a and a lower horizontal carriage beam 143b. The fourth sheeting 145b is extensible and retractable in response to horizontal movement of the shuttle 150.

[0053] Third sheeting 145a is operatively coupled with a third spool 144a and is extensible and retractable by unwinding and winding about third spool 144a. In the embodiment of Figs. 1- 5, third spool 144a is disposed within first vertical carriage beam 142a. In other embodiments, third spool 144a may be coupled with first vertical carriage beam 142a and/or with other structures of carriage 140 in other manners. For example, in some embodiments, third spool 144a may be external to and coupled with first vertical carriage beam 142a. In some embodiments, third spool 144a may be disposed within another housing, container, or other structure which is coupled with first vertical carriage beam 142a, coupled with upper and lower horizontal carriage beams 143a, 143b, and/or coupled with other structures of carriage 140.

[0054] In some embodiments, third spool 144a may be disposed, in whole or in part, within shuttle 150. In some embodiments, third spool 144a may be external to and coupled with and moveable with shuttle 150. In some embodiments, third spool 144a may be disposed within another housing, container, or other structure which is coupled with and moveable with shuttle 150. It is further contemplated that another type of sheeting uptake mechanism, such as the alternatives mechanisms described above, may be utilized in lieu of third spool 144a. [0055] Fourth sheeting 145b is operatively coupled with a fourth spool 144b and is extensible and retractable by unwinding and winding about fourth spool 144b. In the embodiment of Figs. 1-5, fourth spool 144b is disposed within second vertical carriage beam 142b.

[0073] First upper beam member 112a’ and second upper beam member 112b’ are moveable relative to first lower beam member 114a’ and second lower beam member 114b’ to vary the vertical height of tool 100’. As illustrated in Fig. 7, the height of the tool 100’ is in an intermediate state between a minimum height and a maximum height.

[0074] From the position illustrated in Fig. 7, first upper beam member 112a’ and second upper beam member 112b’ may be lowered relative to first lower beam member 114a’ and second lower beam member 114b’ to decrease the overall height of tool 100 and third sheeting 232a’ will retract and wind about spool 234a’ in response to such motion.

In some embodiments, handles 239a, 239b may be provided in other forms, such as recesses, grips, knobs, or other handle forms as will occur to one of skill in the art with the benefit and insight of the present disclosure.

[0085] As illustrated in Fig. 9 and 10, for example, frame 201 includes a first vertical beam 210a and a second vertical beam 210b which extend vertically along a height of the frame 201. In the illustrated example, first vertical beam 210a and second vertical bean 210b are configured and provided as compound beams including multiple constituent components. It shall be appreciated that other embodiments may include different arrangements and types of vertical beams, for example, sliding ladder-type arrangements (e.g., side-by-side, top-to-bottom, or a combination side-by-side and top-to-bottom sliding ladder-type arrangements), partially overlapping arrangements, other types of nested arrangements, or other arrangements as will occur to one of skill in the art with the benefit and insight of the present disclosure. Other embodiments may include fixed-length beam members which may be single-piece fixed-length beam members or multi-piece fixed-length beam members.

[0086] As illustrated in Fig. 9, first vertical beam 210a includes beam member 271a and beam member 272a of upper frame assembly 201a as well as beam member 273a, beam member 274a, beam member 275a, and beam member 276a of lower frame assembly 201b. Beam member 271a and beam member 272a may be operatively coupled with one another to provide a unitary, fixed-length portion of first vertical beam 210a. Beam member 273a, beam member 274a, beam member 275a, and beam member 276a may be operatively coupled with one another to provide a unitary, fixed-length portion of first vertical beam 210a.

[0087] First vertical beam 210a and its constituent beam members 271a, 272a, 273a, 274a, 275a, 276a may be provided in a number of forms. In some embodiments, constituent beam members 271a, 272a, 273a, 274a, 275a, 276a may be provided as the same type or a substantially similar type as one another. In some embodiments, constituent beam members 271a, 272a, 273a, 274a, 275a, 276a may be provided as various or varied types. Fig. 11 illustrates one example type of beam members 271a, 272a, 273a which are provided in the form of T-slot aluminum extrusions each including a plurality of T-slots 373 which are configured to receive connectors such as connector 374 and connector 375. Connector 374 is an example of a fixed connector which is configured and operable to rigidly couple bracket 281a of adjustment assembly 280a with beam member 272a of upper frame assembly 201a. Connector 375 is an example of a slidable connector which is configured and operable to slidably couple bracket 281a of adjustment assembly 280a with beam member 271a of lower frame assembly 201b.

[0088] The respective connections established by connector 374 and connector 375 accommodate and participate in vertical movement of upper frame assembly 201a relative to lower frame assembly 201b, for example, when raising or lowering force is applied to adjustment assembly 280a by a user of tool 200 to either raise or lower of upper frame assembly 201a relative to lower frame assembly 201b effective to extend or retract the overall vertical height of tool 200. Such adjustment may be performed, for example, to provide a macro-adjustment of the overall vertical height of tool 200 relative to a wall framing. For example, a user may adjust the overall vertical height of tool 200 to be greater than the distance between underlying floor surface 19 and a ceiling joist or an upper horizontal stud of a wall framing (e.g., structures substantially the same as or similar to ceiling joist 13 or upper horizontal stud 12 illustrated and described in connection with Fig. 1).

[0089] After performing macro-adjustment such as the above-described adjustment, a user may apply downward force to frame 201, for example, by stepping on second horizontal beam 222 of lower frame assembly 201b or on a shelf-type protrusion operatively coupled therewith, such as shelf 223 which is illustrated in phantom for clarity. Such application of force may be effective to compress support assembly 219a effective to reduce the overall vertical height of tool 200 to be greater than the distance between underlying floor surface 19 and the ceiling joist or the upper horizontal stud of the wall framing. A user may thereafter adjust the positioning of tool 200 to locate tool 200 beneath the ceiling joist or the upper horizontal stud of the wall framing. Once so positioned, a user may release or reduce the downward force applied to frame 201 and tool 200 may expand due to the relaxation of support assembly 219a and tool 200 may apply force effective to wedge or retain tool 200 in a position suitable for installation of insulation.

[0090] As illustrated in Fig. 10, second vertical beam 210b includes beam member 271b and beam member 272b of upper frame assembly 201a as well as beam member 273b, beam member 274b, beam member 275b, and beam member 276b of lower frame assembly 201b. Beam member 271b and beam member 272b may be operatively coupled with one another to provide a unitary, fixed-length portion of second vertical beam 210b. Beam member 273b, beam member 274b, beam member 275b, and beam member 276a may be operatively coupled with one another to provide a unitary, fixed-length portion of second vertical beam 210b.

[0091] Second vertical beam 210b and its constituent beam members 271b, 272b, 273b, 274b, 275b, 276b may be provided in a number of forms. In some embodiments, constituent beam members 271b, 272b, 273b, 274b, 275b, 276b may be provided as the same type or a substantially similar type as one another. In some embodiments, constituent beam members 271b, 272b, 273b, 274b, 275b, 276b may be provided as various or varied types. In some embodiments, one or more of beam members 271b, 272b, 273b, 274b, 275b, 276b may be provided in the form of T-slot aluminum extrusions such as the form of a beam members 271a, 272a, 273a illustrated and described in connection with Fig. 11.

[0092] Connectors substantially the same as or similar to connector 374 and connector 375 illustrated and described in connection with Fig. 11 may be utilized to similarly rigidly couple bracket 281b of adjustment assembly 280b with beam member 272b of upper frame assembly 201a and slidably couple bracket 281b of adjustment assembly 280b with beam member 271b of lower frame assembly 201b. The respective connections established by connector 374 and connector 375 accommodate and participate in vertical movement of upper frame assembly 201a relative to lower frame assembly 201b, for example, via the macro-adjustment, compression, and release operations described above.

[0093] Lock mechanisms 282a, 282b of adjustment assemblies 280a, 280b may be manipulated by a user in connection with the adjustment operations described above. For example, a locking end of lock mechanisms 282a, 282b may be configured to selectably engage and disengage with beam members 273a, 273b, respective, for example by extending into and retracting from receiving holes or apertures provided in 273a, 273b. A plurality of such receiving holes or apertures may be provided in 273a, 273b at different vertical positions to accommodate and facilitate locking of the upper frame assembly 201a relative to lower frame assembly 201b.

[0094] In the illustrated example, lock mechanisms 282a, 282b are configured and provided as a thumb button-type locking mechanisms configured to selectably lock and unlock in response to application of force to user-accessible ends of lock mechanisms 282a, 282b, for example, by application of force by a user’s thumbs when gripping handles 239a, 239b. A number of thumb button-type locking mechanisms are contemplated including, for example, mechanisms in which locking ends of lock mechanisms 282a, 282b are biased into engagement with beam members 273a, 273b and the application or relaxation of force to user accessible ends is effective to disengage lock mechanisms 282a, 282b from beam members 273a, 273b permitting the aforementioned adjustment. Such mechanisms may include various linkages, levers, cams, or other force-bearing or transfer components configured to transfer or translate application of force in a direction toward tool 200 into retraction of locking ends of lock mechanisms 282a, 282b. In some embodiments, the biasing force directions of lock mechanisms 282a, 282b may be reversed such that lock mechanisms 282a, 282b are biased out of engagement with beam members 273a, 273b. In some embodiments, regardless of the biasing direction, the application of force to user accessible ends of lock mechanisms 282a, 282b may be effective to toggle lock mechanisms 282a, 282b from engaged and disengaged states from beam members 273a, 273b, for example, in a push-to-engage, next-push-to-release set of operations. In some embodiments, lock mechanisms 282a, 282b may be provided in the form of trigger-type mechanisms (e.g., finger trigger-type mechanisms) or pull-type mechanisms (e.g., finger pull-type mechanisms).

[0095] An upper carriage 240a extends horizontally intermediate vertical beams 210a, 210b and is vertically moveable along at least a portion of the vertical height of vertical beams 210a, 210b.
