TECHNICAL FIELD
The present disclosure relates generally to enclosures for snow throwers and other vehicles.
BACKGROUND
A conventional snow thrower (also referred to as a “snow blower”) is a powered machine for removing snow from an area where it is not wanted, such as a driveway, sidewalk, roadway or runway. Conventional snow throwers can use either electric power, or a gasoline or diesel engine to throw snow to another location or into a container to be hauled away.
Although some of the smaller snow throwers are pushed by the operator, it is common for snow throwers to be self-propelled, using either large wheels that can be equipped with tire chains or, in some cases, tracks. An operator usually walks behind a conventional self-propelled snow thrower. From this position, the operator can control the snow thrower. Controls for conventional snow throwers can include a clutch for engaging/disengaging the drive system that propels the snow thrower, a clutch for engaging/disengaging the snow handling system, a deflector for setting the distance that snow is thrown from the discharge chute, and/or a chute crank for setting the direction that snow is thrown from the discharge chute. Additional controls can include a speed regulator, e.g., an engine throttle, or a key for authorizing use of the snow thrower.
A snow thrower is typically used in cold, wet, damp, rainy, snowy, and/or windy conditions. Accordingly, an operator often must wear bulky winter clothes to stay warm and dry while using the snow thrower. The combination of inclement weather and winter clothes may adversely affect the ability of the operator to clear the snow in a timely and effective manner. To minimize discomfort and productivity losses, it is desirable to provide a shelter for the operator of a snow thrower.

The embodiment shown in FIGS. 2A-2E includes a bar assembly 210, a back hoop assembly 240, a front pole assembly 250, and a mounting assembly 300.
Referring to FIGS. 2A-2E, the bar assembly 210 can include a center bar 212, a pair of end bars 214a and 214b, and a pair of corner bars 228a and 228b. The corner bars 228a and 228b couple the center bar 212 to the end bars 214a and 214b, respectively. In the embodiment shown in FIGS. 2A-2E, a left side of the bar assembly 210, which includes the end bar 214a and the corner bar 228a, is a mirror image of the right side of the bar assembly 210, which includes the end bar 214b and the corner bar 228b. As they are used in this disclosure for the purposes of description only, the terms “left” and “right” are defined with respect to a person standing between the end bars 214a and 214b and facing toward the center bar 212. The terms “front” or “forward” and “back” or “rearward” are also defined with respect to the same frame of reference for the purposes of description only.
The components of the bar assembly 210 can be releasably coupled to one another. For example, swaged portions can be telescopically received in tubular portions. As it is used in this disclosure, the term “swaged” refers to a constricted cross-section, e.g., a reduced diameter.
Continuing to refer to FIGS. 2A-2E, the back hoop assembly 240 can include a back hoop top 242, a pair of back hoop sides 244a and 244b, and a pair of back hoop corners 248a and 248b. The back hoop corners 248a and 248b couple the back hoop top 242 to the back hoop sides 244a and 244b, respectively. In the embodiment shown in FIGS. 2A-2E, a left side of the back hoop assembly 240, which includes the back hoop side 244a and the back hoop corner 248a, is a mirror image of the right side of the back hoop assembly 240, which includes the back hoop side 244b and the back hoop corner 248b. The back hoop side 244a can include a lower segment 245a that couples with the end bar 214a, an upper segment 246a that couples with the back hoop corner 248a, and a sleeve 247a that couples the lower and upper segments 245a and 246a. Similarly, the back hoop side 244b can include a lower segment 245b that couples with the end bar 214b, an upper segment 246b that couples with the back hoop corner 248b, and a sleeve 247b that couples the lower and upper segments 245b and 246b.
Continuing to refer to FIGS. 2A-2E, the front pole assembly 250 can include a front pole central section 252 and a pair of front pole end sections 258a and 258b. The front pole central section 252 can include a single rod or a plurality of rods coupled in series, e.g., with sleeves. In the embodiment shown in FIGS. 2A-2E, the front pole central section 252 includes five rods 254a-254e coupled together with four sleeves 256a-256d. The sleeves 256 can include polyvinyl chloride (PVC) tubes that are pressed onto adjoining ends of the rods 254. According to other embodiments, the sleeves 256 can include metal ferrules that can be crimped onto an end of a first adjoining rod 254 and slid over an end of a second adjoining rod 254. Optionally, an elastic cord (not shown) can be disposed in a longitudinal hole extending throughout the assembled front pole central section 252. The front pole end section 258a couples the corner bar 228a with the front pole central section 252, and the front pole end section 258b couples the corner bar 228b with the front pole central section 252.
A sequence for assembling the frame 200 according to an embodiment of the present disclosure is illustrated in FIGS. 2F-2H. As shown in FIG. 2I, some embodiments of the present disclosure can include an arrangement of the bar assembly 210 to accommodate the presence and operation of a control C for the powered machine. For example, the height h of the center bar 212 and corner bars 228 relative to the end bars 214 can accommodate rotation of a crank for adjusting the discharge chute of a snow thrower.
FIGS. 3A and 3B are perspective views showing a spring clip 290 according to an embodiment of the present disclosure. The spring clip 290 can be used, for example, to releasably secure together the bars of the bar assembly 210. The spring clip 290 includes a peg 290a disposed on a resilient portion 294. In the embodiment shown in FIG. 3, the resilient portion 294 includes a first arm 294a coupled to the projection 290a, a second arm 294b, and a bight 294c coupling the first arm 294a to the second arm 294b. The spring clip 290 biases the projection 290a away from the second arm 294b. In the embodiment shown in FIGS. 2A-2E, the resilient portion 294 is disposed inside a tubular portion of an inner bar of the bar assembly 210, and the peg 290a is biased into aligned holes extending through the telescopically nested inner and outer bars of the bar assembly 210. Depressing the peg 290a so as to disengage from a least the hole through the outer bar allows the telescopically nested bars to be separated or angularly reoriented with respect to one another.
FIG. 4A is a perspective view showing the mounting assembly 300 according to an embodiment of the present disclosure. FIG. 4B is an exploded view showing components of the mounting assembly 300. In the embodiment shown in FIGS. 4A and 4B, the mounting assembly 300 includes a lower mounting post 310, an upper mounting post 330, an elbow 350, an optional extender tube 360, a plate 370, and a pair of U-bolts 380.
Referring to FIGS. 4A and 4B, the lower mounting post 310 can include a base 312 and a spindle 324. The base 312 includes a concave portion 314 and mounting holes 318. In the embodiment shown in FIGS. 4A and 4B, the concave portion 314 can be defined by three bends 314a-314c that define four regions 312a-312d of the base 312. The two interior regions 312b and 312c are obliquely oriented with respect to one another, and the exterior regions 312a and 312d are shown lying in a common plane, but could lie in parallel planes. The holes 318, four are included in the embodiment shown in FIGS. 4A and 4B, are disposed in the exterior regions 312a and 312d. The spindle 324 extends along a first axis A1 between a fixed end 324a and a free end 324b. The fixed end 324a is coupled, e.g., welded, to the base 312. In the embodiment shown in FIGS. 4A and 4B, the spindle 324 projects (e.g., orthogonally with respect to the common plane defined by the exterior regions 312a and 312d) from the backside of the concave portion 314.
Continuing to refer to FIGS. 4A and 4B, the upper mounting post 330 extends along a second axis A2 between a clamp end 330a and a free end 330b. A clamp 334 is coupled at the clamp end 330a. The clamp 334, which is configured to receive the bar assembly 210, can include a longitudinally split tube 336 having first and second flanges 338a and 338b disposed respectively on opposite sides of the split. In an expanded configuration of the clamp 334, the first flange 338a is spaced from the second flange 338b a first distance, and in a contracted configuration of the clamp 334, the first flange 338a is spaced from the second flange 338b a second distance that is less than the first distance. A fastener 340, e.g., a bolt and washer, penetrates through the first flange 338a and threadably engages the second flange 338b. Alternatively, the fastener 340 can include a bolt that penetrates through the first and second flanges 338a and 338b and threadably engages a nut. In the expanded configuration of the clamp 334, the fastener 356 is loosened to adjust the spacing between the first and second flanges 338a and 338b to the first distance such that the bar assembly 210 is released by the clamp 334 with respect to the upper mounting post 330. Accordingly, the upper mounting post 330 can be angularly oriented about a tilt axis T with respect to the bar assembly 210, thereby facilitating fore and aft tilting of the enclosure 100 with respect to a powered machine upon which the enclosure is mounted. In the contracted configuration of the clamp 334, the fastener 340 is tightened to adjust the spacing between the first and second flanges 338a and 338b to the second distance such that the bar assembly 210 is secured by the clamp 334 with respect to the upper mounting post 330. The free end 330b of the upper mounting post 330 can be swaged and/or may be tubular.
Continuing to refer to FIGS. 4A and 4B, the elbow 350 extends between a first end 350a and a second end 350b. In the embodiment shown in FIGS. 4A and 4B, the elbow 350 includes a 90° bend in a central section 350c between the first and second ends 350a and 350b. The central section 350c can alternatively be bent at angles other than 90°. The first end 350a, the second end 350b, and the central section 350c can be manufactured as a single, homogenous unit or can be manufactured as an assembly of individual pieces coupled together. The first end 350a, which is configured to receive the spindle 324, can include a longitudinally split tube 352 having first and second flanges 352a and 352b disposed respectively on opposite sides of the split. In an expanded configuration of the tube 352, there is a first gap between the first flange 352a and the second flange 352b. In a contracted configuration of the tube 352, there is a second gap between the first flange 352a and the second flange 352b, and the second gap is less than the first gap. A fastener 356, e.g., a bolt and washer, penetrates through the first flange 352a and threadably engages the second flange 352b. Alternatively, the fastener 356 can include a bolt that penetrates through the first and second flanges 352a and 352b and threadably engages a nut. In the expanded configuration of the tube 352, the fastener 356 is loosened to adjust the gap between the first and second flanges 352a and 352b to the first gap such that the tube 352 releases the angular and/or longitudinal positional relationship of the spindle 324 with respect to the elbow 350. In the contracted configuration of the tube 352, the fastener 356 is tightened to adjust the gap between the first and second flanges 352a and 352b to the second gap such that the tube 352 secures the angular and/or positional relationship of the spindle 324 with respect to the elbow 350. The second end 350b is configured to receive the extender tube 360 that in-turn receives the free end 330b of the upper mounting post 330. A fixing arrangement 358 can releasably secure the relative angular and/or longitudinal position of the elbow 350 and the extender tube 360, and a fixing arrangement 368 can releasably secure the relative angular and/or longitudinal position of the extender tube 360 and the upper mounting post 330. In the embodiment shown in FIGS. 4A and 4B, the fixing arrangement 358 can include a set screw 358a in threaded engagement with a socket 358b on the second end 350b of the elbow 350, and the fixing arrangement 368 can include a set screw 368a in threaded engagement with a socket 368b on the extender tube 360. In set configurations of the fixing arrangements 358 and 368, the set screw 358a is rotated into contiguous frictional engagement with the extender tube 360 such that the fixing arrangement 358 secures the angular and/or positional relationship of the extender tube 360 with respect to the elbow 350, and the set screw 368a is rotated into contiguous frictional engagement with the upper mounting post 330 such that the fixing arrangement 368 secures the angular and/or longitudinal positional relationship of the upper mounting post 330 with respect to the extender tube 360. In released configurations of the fixing arrangements 358 and 368, the set screw 358a is rotated out of contiguous frictional engagement with the extender tube 360 such that the fixing arrangement 358 releases the angular and/or longitudinal positional relationship of the extender tube 360 with respect to the elbow 350, and the set screw 368a is rotated out of contiguous frictional engagement with the upper mounting post 330 such that the fixing arrangement 368 releases the angular and/or longitudinal positional relationship of the upper mounting post 330 with respect to the extender tube 360.
In other embodiments according to the present disclosure, the extender tube 360 can be eliminated such that the second end 350b directly receives the free end 330b of the upper mounting post 330. Accordingly, in a set configuration of the fixing arrangement 358, the set screw 358a is rotated into contiguous frictional engagement with the upper mounting post 330 such that the fixing arrangement 358 secures the angular and/or longitudinal positional relationship of the upper mounting post 330 with respect to the elbow 350. In a released configuration of the fixing arrangement 358, the set screw 358a is rotated out of contiguous frictional engagement with the upper mounting post 330 such that the fixing arrangement 358 releases the angular and/or longitudinal positional relationship of the upper mounting post 330 with respect to the elbow 350.
Continuing to refer to FIGS. 4A and 4B, the plate 370 and the pair of U-bolts 380 cooperate with the base 312 of the lower mounting post 310 to releaseably secure the frame 200 with respect to a portion of a power machine (not shown in FIGS. 4A and 4B) to which the enclosure 100 is coupled. According to at least one embodiment of the present disclosure, the U-bolts 380 partially surround the portion of the power machine (not shown in FIGS. 4A and 4B) and are pulled into contiguous frictional engagement with the portion of a power machine (not shown in FIGS. 4A and 4B) by cooperating nuts 382. FIGS. 4C-4G illustrate a sequence for assembling the mounting assembly 300 according to an embodiment of the present disclosure is illustrated in FIGS. 4A and 4B.
In the embodiments shown in FIGS. 2A-2E, 3A and 3B, 4A and 4B, components of the bar assembly 210, the back hoop assembly 240, the front pole end sections 258, and the mounting assembly 300 can be made of metal, e.g., 1005 steel, which may be finished, e.g., painted or powder coated. In other embodiments, the components can be made of other suitably strong and durable materials. In the illustrated embodiments, individual components of the bar assembly 210, e.g., end bars 214, can be made of sections of metal tubing that are welded, brazed, soldered, adhered or otherwise physically coupled. Sleeves made of polyvinylchloride (PVC) may be use to couple the components of the back hoop assembly 240. With regard to the front pole assembly 250, the rods 254a-254e can be manufactured from reinforced fiberglass. The sleeves 256 can include PVC tubes that are pressed onto ends of adjoining rods 254. According to other embodiments, the sleeves 256 can include metal ferrules, e.g., aluminum, that can be crimped onto an end of a first adjoining rod 254 and slid over an end of a second adjoining rod 254.
FIG. 5A is a perspective view showing the skin 400 according to an embodiment of the present disclosure. The skin 400 according to the embodiment shown in FIG. 5A includes a front skin panel 420 (FIG. 5B), a top skin panel 440 (FIG. 5C), and a pair of side skin panels 460a and 460b (only one side skin panel 460 is shown in FIG. 5D).
Referring to the embodiment shown in FIGS. 5A and 5B, the front skin panel 420 includes a primary viewing panel 422, e.g., manufactured from a substantially transparent material such as clear PVC, and at least one supplemental viewing panel 424 (three supplemental viewing panels 424a-424c are included in the embodiment shown in FIG. 5A). The viewing panels 422 and 424 provide visibility for the powered machinery operator inside the enclosure 100. The primary viewing panel 422 and the supplemental viewing panel 424 are coupled, e.g., by sewing, to a fabric frame 428 that can be manufactured from PVC, polyester, nylon or another suitable fabric, roll good, or sheet. The fabric frame 428 can form a border at least partially around the peripheries of the primary viewing panel 422 and the supplemental viewing panel 424. In the embodiment shown in FIGS. 5A and 5B, the front skin panel 420 includes wings 420a and 420b that, in combination with the supplemental viewing panel 424, provide a flared skirt arrangement to the lower front portion of the skin 400. The flared skirt can accommodate portions of the power machinery. Referring additionally to FIG. 5G, the skin 400 may include one or more closure adjusters 430 (e.g., two zippers 430a and 430b are included in the embodiment shown in FIGS. 5A and 5B) for adjusting the skin 400 to accommodate the structure of a particular powered machine and/or to allow the operator within the enclosure 100 to access the powered machinery. For example, in the case of a snow thrower, the closure adjusters 430 can facilitate operator access to one or more controls such as the chute crank for setting the direction that snow is thrown from the discharge chute of a snow thrower. In the embodiment shown in FIGS. 5A and 5B, the closure adjusters 430 divide the supplemental viewing panel 424 into the three supplemental viewing panels 424a-424c.
With reference to FIGS. 5A and 5C, the top skin panel 440 can form another partial portion of the border around the periphery of the primary viewing panel 422. The top skin panel 440 can include pockets 442 and 444 which can receive the back hoop top 242 and the front pole central section 252, respectively. Thus, the pockets 442 and 444 maintain the top skin panel 440 in a desired configuration corresponding to the shape and arrangement of the back hoop top 242 and the front pole central section 252.
With reference to FIGS. 5A and 5D, the side skin panel 460 includes a secondary viewing panel 462 that can also be manufactured from a substantially transparent material such as clear PVC. The secondary viewing panel 462 provides lateral visibility for the powered machinery operator inside the enclosure 100. The secondary viewing panel 462 is coupled, e.g., by sewing, to a fabric frame 464 that can be manufactured from PVC, polyester, nylon or another suitable fabric, roll good, or sheet. The fabric frame 464 can form a border around the periphery of the secondary viewing panel 462. In the embodiment shown in FIG. 5A, each side skin panel 460 is coupled, e.g., sewn, to the front skin panel 420 and the top skin panel 440. A pocket 466 which can receive the back hoop sides 244 can be formed at the rear edge of the side skin panels 460. A lower front portion 468a of the side skin panels 460 can be configured to be coupled with a wing 420 and/or a corner bar 228, and a lower rear portion 468b can be configured to be coupled with an end bar 214. Optional pouches 470 can be coupled to the inside of the side skin panels 460. For example, FIG. 5E shows an embodiment of a sand pouch 470a and FIG. 5F shows an embodiment of a convenience pouch 470b. Either or both of the pouches 470a and 470b can be coupled to the inside of the side skin panel 460. The sand pouch 470a can provide a supply of sand or a de-icing agent to provide improved traction for the operator and/or the powered machinery. The convenience pouch 470b can provide storage for a garage door opener, gloves, a cell phone, or another accessory that the powered machinery operator may wish to have in the enclosure 100. The pouches 470 can be coupled to the side skin panels 460 by sewing, by a hook and loop fastener, or any other suitable coupling. FIGS. 5H-5K illustrate a sequence for positioning the skin 400 on the frame 200 according to an embodiment of the present disclosure.
Referring to FIG. 6A, the skin 400 is fitted over and coupled to the frame 200 such that the enclosure 100 is defined. The front skin panel 420 is coupled, e.g., with hook and loop straps, to the front pole end sections 258 of the front pole assembly 250, the top skin panel 440 is formed with pockets that receives the front pole central section 252 of the front pole assembly 250 and/or the back hoop top 242 of the back hoop assembly 240, and the side skin panels 460a and 460b are coupled, e.g., with hook and loop straps, to the corner bars 228a and 228b and/or end bars 214 of the bar assembly 210. At least one mounting assembly 300 couples the enclosure 100 to a piece of powered machinery, e.g. a snow thrower. As shown in the embodiment illustrated in FIG. 6A, lower mounting post 310 can be coupled with the pair of U-bolts 380 to the handle bars or another bar on the powered machinery. The upper mounting post 330 can be coupled to the bar assembly 210. Adjustability with respect to the axes A1, A2 and T facilitates mounting the enclosure 100 in any number of arrangements with respect to the powered machinery, as well as permits the enclosure 100 to be dismounted from a first piece of powered machinery and then remounted on a second piece of powered machinery. As shown in FIG. 6B, the enclosure 100 can be tilted about the axis T to accommodate operators of various heights. For example, tilting the enclosure forward can provide additional headroom at the back of the enclosure 100. Moreover, the connection(s) between the upper mounting post 330, the optional extender tube 360, and the elbow 350 provide suitable locations for dismounting and/or remounting the enclosure 100 with respect to one or more pieces of powered machinery.
FIG. 7A is a perspective view showing another embodiment according to the present disclosure of an enclosure 1000. The enclosure 1000 includes a frame 1200 (see FIG. 7B) supporting a skin 1400 (see FIG. 7C).
FIG. 8A is a perspective view showing the frame 1200 according to an embodiment of the present disclosure. FIGS. 8B-8D are front, side and top views, respectively, showing the frame 1200.
