Definitions

  • Trucks transport many different items.
  • Some trucks such as pick-ups, include a bed that is mounted onto the truck's frame to carry items.
  • the items carried by such trucks vary widely. For example, some trucks and semi-trailers transport liquids while some transport solid items.
  • Some trucks transport perishable items and thus require a refrigerated semi-trailer also known as a reefer.
  • the corrugated form of the bed provides the bed substantial strength and stiffness so that the bed can carry large, heavy items.
  • the corrugated form also allows one to more easily remove items from the bed by: 1 ) preventing a vacuum from forming between the bed and the item; 2) making it easier to slide an item across the bed; and/or 3) allowing one to easily access the bottom of the item to lift the item off the bed.
  • Two general methods are typically used to clean the bed of a pick-up truck or semi-trailer.
  • One method includes using water to hose down the bed. This works well for pick-up trucks and semi-trailers but if the bed is covered then one typically has to let the bed sit for a couple of hours to dry out before loading other items onto the bed.
  • Another method includes using a standard broom to sweep out debris. Unfortunately, though, such brooms don't work well on uneven or contoured surfaces like a corrugated bed has. It's very difficult for a broom's bristles to contact both levels of the corrugated surface at the same time.
  • a single semi-trailer typically includes 40 or more valleys in its bed, and a pick-up truck's bed often includes 15 or more valleys.
  • the distance between each valley of the corrugated bed can vary from bed to bed and from region to region within a single bed. This variation in the distance between the valleys can also make cleaning the bed with a broom difficult.
  • a head for a sweeper that may be used to clean a contoured surface, includes: a frame, two or more feet, and a suspension that couples each of the two or more feet to the frame and allows each of the two or more feet to move relative to its adjacent foot.
  • the frame extends in a direction that is substantially perpendicular to the direction that the head moves when the head is moved across the contoured surface to clean the surface.
  • Each of the two or more feet has an end that moves material, such as debris or liquid, located on the surface, as the frame of the head is moved across the surface.
  • one or more feet may include bristles; to squeegee away liquid left in the valleys after hosing a bed down, the one or more feet may include a squeegee.
  • the suspension allows each of the two or more feet to move relative to its adjacent foot in the direction that the frame extends, as the head is moved across the contoured surface to clean the surface.
  • the head includes two or more feet, each of which may be inserted into a respective one of the many valleys of a corrugated bed, one may use the head to simultaneously sweep out debris and/or liquid from multiple valleys of a corrugated bed. And, because the suspension allows each of the two or more feet to move relative to each other in a direction that is substantially perpendicular to the sweeping direction, one may use the head to quickly and easily sweep a bed whose valleys are not consistently spaced apart. Likewise, one may use the head to quickly and easily sweep two different beds whose valleys are not the same distance apart, without having to manually adjust the distance between each foot after sweeping one bed but before sweeping the other bed.

And, because the suspension 44 allows each of the two or more feet 42 to move relative to each other in a direction 48 or 50 that is substantially perpendicular to the sweeping direction 36 or 38, one may use the head 32 to quickly and easily sweep a pick-up's bed or a semi-trailer's bed whose valleys 46 are not consistently spaced apart. Likewise, one may use the head 32 to quickly and easily sweep two different beds whose valleys 46 are not the same distance apart, without having to manually adjust the distance between each foot 42 after sweeping one bed but before sweeping the other bed.
  • the frame 40 may be configured as desired.
  • the frame 40 includes aluminum material that has been extruded in the form of a channel.
  • the frame 40 also includes a first end 52, a second end 54, a length that extends in the channel's extruded direction between the first and second ends 52 and 54, respectively, and a width sized to surround a portion of the two or more feet 42 when the feet 42 are coupled to the frame 40.
  • the channel holds the feet 42 side-by-side, and does not allow the head 32 to substantially deform. If the head 32 substantially deformed while one moved it, one or more of the feet 42 could exert excessive force against a side of a valley 46 and resist the movement of the head 34, in effect binding the head 34.
  • the frame 40 may include any other material, such as plastic and/or wood.
  • the frame 40 may be configured in the shape of a rectangle or closed channel. Such a configuration can increase the stiffness of the frame 40 and may allow for other configurations of the suspension 44 to fix and/or releasably couple two or more feet 42 to the frame 40.
  • each of the two or more feet 42 may be configured as desired to move debris and/or liquid across a contoured surface.
  • each of the two or more feet 42 are configured to squeegee liquid from a contoured surface 34 that has U-shaped regions between ⁇ -shaped regions.
  • each foot 42 includes a body 56 that is sized to nest within a valley 46, and a frame 58 to stiffen the body 56 so that the body 56 stays in contact with the contoured surface of the valley 46 as one moves the head 32 across the surface 34.
  • the body 56 includes a large bore 59 that allows the foot 42 to compress toward the head's frame 40. As shown in FIG.

  • the amount of force that the spring 64 exerts on the feet 42 that it lies between may be any desired force.
  • the amount of force is moderate to allow the feet 42 to easily move toward or away from their adjacent feet 42 as the contoured surface changes.
  • the amount of force may be more to provide more support to the feet 42. This may be desirable if one is sweeping a large amount of debris from a surface or squeegeeing a large amount of liquid from the surface.
  • the amount of force may be less to allow the feet 42 to more easily adjust to a changing contoured surface.
  • the force of each spring 64 in the suspension 44 may be different than the other springs 64.
  • the suspension 44 may fix, not releasably, two or more feet 42 to the frame 40. This may be desirable to provide a head for a sweeper that may be used to clean a contoured surface whose contours are common and remain consistent. In such situations there may not be a need to change one or more of the feet 42 to match a corresponding change in the contoured surface to be cleaned.

Abstract

L'invention concerne une tête pour un balai utilisé pour nettoyer des surfaces profilées, qui comprend : un cadre, au moins deux pieds, et une suspension qui accouple chacun des au moins deux pieds au cadre et permet à chacun des au moins deux pieds de se déplacer par rapport à son pied adjacent. Le cadre s'étend dans une direction qui est sensiblement perpendiculaire à la direction dans laquelle la tête se déplace à travers la surface profilée pour nettoyer la surface. Chacun des au moins deux pieds a une extrémité qui déplace un matériau, tel que des débris ou un liquide, situé sur la surface, à mesure que le cadre de la tête est déplacé à travers la surface. Pour balayer des débris, le ou les pieds peuvent comprendre des crins; pour racler un liquide laissé dans les creux après arrosage d'un lit vers le bas, le ou les pieds peuvent comprendre une raclette. La suspension permet à chacun des au moins deux pieds de se déplacer par rapport à son pied adjacent dans la direction dans laquelle le cadre s'étend, à mesure que la tête est déplacée à travers la surface profilée pour nettoyer la surface.
