The present invention relates generally to the field of dasher boards and accessories for use in bounded sports arenas such as hockey and soccer arenas. More specifically, the present invention pertains to soft caps for absorbing player impact against dasher boards.
BACKGROUNDDasher boards are used in bounded sports arenas to demarcate a general boundary line dividing a playing field from on-looking spectators and to absorb impact from players as they maneuver the outer periphery of the playing field. The dasher boards are typically designed to be secure and stable in order to withstand vibration or shock while also providing the spectators with a clear and unobstructed view of the game. In the design of ice hockey rinks, for example, such dasher boards are designed to withstand significant impacts caused by hockey players skating or being pushed into the boards throughout the course of a game while also allowing spectators to view the game without obstructions.
A typical dasher board for a hockey rink includes a lower frame, an anchoring system for attaching the lower frame to the rink surface, an upper shielding pane, and a support mechanism for connecting the upper shielding pane to the lower frame. The dasher boards can be fabricated as either a fixed, continuous frame forming the boundary, or in demountable sections typically eight feet in length that are assembled together in an end-to-end fashion to form the boundary. In some designs, an ice retainer or ice dam is sometimes used on the bottom of the lower frame to prevent ice from creeping away from the playing surface.
More recent trends have focused on imparting greater flexibility and absorption capabilities to dasher boards in order to dampen the significant impacts that can occur during play. The “flexibility” of the dasher board is generally understood as the displacement of the dasher board in response to an impact, which can vary from as little as 1/16″ for systems that utilize boards mounted to a concrete block wall to as much as 2″ to 3″ for demountable systems which employ loose anchors and bolts and are constructed from aluminum frames. An illustrative dasher board system employing several features for absorbing player impact is described in greater detail in U.S. Pat. No. 6,004,217 to Johnston et al., which is incorporated herein by reference in its entirety.
Although many existing dasher board systems employ features to absorb the energy from an impact, the surfaces of the dasher boards are typically made from hard materials such as high-density polyethylene (HDPE) or fiberglass which are not absorptive. Due to the more aggressive playing style and faster speeds associated with contact sports such as hockey, there is an ongoing need in the art for dasher boards having shock absorption features that lessen player impact while also providing spectators with a clear and unobstructed view of the playing field.
SUMMARYThe present invention relates generally to soft caps for absorbing player impact against dasher boards. An illustrative soft cap for use with a dasher board can include an elongated body defining a number of absorption ribs which act to absorb impact forces exerted against the cap. The absorption ribs may be spaced apart from each other via a number of channels, and can extend lengthwise in a direction either parallel or transverse to the length of elongated body. A curved section formed on one or both sides of the elongated body can be configured to fit adjacent to the hard edges of the lower frame. In some embodiments, the elongated body can be formed from a soft material such as low-density polyethylene, which in contrast to the harder materials typically used in forming dasher boards, can be configured to displace or yield when compressed to absorb impact energy.
The soft cap can be provided as part of a dasher board assembly including a lower frame assembly and a number of upper shielding panes. The frame assembly can include an impact panel attached to a number of vertical posts and stringers. An upper section of the frame assembly may define an upper periphery that can be configured to support the soft cap. In some dasher board systems, the soft cap can be coupled to the upper periphery of the frame assembly adjacent the impact-side of the upper shielding panes. In other dasher board systems, the soft cap can be coupled to the lower frame, either above or adjacent to an existing sill. In use, the soft cap may form a bumper along all or a portion of the upper periphery of the frame assembly in order to absorb impact forces caused when a player strikes the dasher board.

Referring now to
Each dasher board assembly 12 can include a lower frame assembly 14 adapted to vertically support a number of upper shielding panes 16,18. The lower frame assembly 14 can include a first end section 20, a second end section 22, a lower section 24, and an upper section 26. The lower section 24 of the frame assembly 14 can be anchored to the underlying playing surface 28 of the arena or rink via an anchoring mechanism in order to secure the dasher board assembly 12 in place.
The impact side of the frame assembly 14 can be covered with a high-density polyethylene or fiberglass impact panel 30, which can be supported to the frame assembly 14 using several vertical posts and stringers as described in greater detail with respect to
The shielding panes 16,18 can be made from a variety of materials including tempered glass, acrylic, Plexiglass, or other suitable material. In dasher board systems 10 employing tempered glass, the shielding panes 16,18 will typically be about ½″ thick on the sides of the arena and about ⅝″ thick on the ends and radius sections of the arena. Acrylic shielding panes 16,18, on the other hand, are typically about ½″ thick at all locations. The shielding panes 16,18 may have a horizontal length of about 4 feet, with two such panels 16,18 typically forming an 8 foot length of dasher board. The number and length of the shielding panes may vary, however, depending on the dimensions of each dasher board assembly 12.
The shielding panes 16,18 can be vertically supported at least in part using a sill 36 located on the upper periphery 38 of the frame assembly 14 adjacent to the non-impact or spectator side of the dasher board assembly 12. The sill 36 may extend along all or a portion of the length of the frame assembly 14, and can be configured to abut the non-impact side of the shielding panes 16,18 for support. The sill 36 may be formed from a relatively hard material such as high-density polyethylene (HDPE), which acts to support the shielding panes 16,18 in place within the frame assembly 14 when deflected in the direction indicated generally by the arrows 40.
As can be further seen in
The soft cap 42 can be configured to cover the upper periphery 38 of the frame assembly 14 adjacent to the impact side of the shielding panes 16,18. A first edge 54 of the soft cap 42 can be configured to overhang a portion of the impact panel 30, as shown, forming a bumper to cover the hard edges of the panel 30 during an impact. A second edge 56 of the soft cap 42, in turn, can be configured to engage the impact side of the shielding panes 16,18, thereby supporting the impact side of the shielding panes 16,18 opposite the second edge 50 of the sill 36. In some embodiments, the slot or U-shaped support channel 46 can be spring loaded against the second edge 56 of the soft cap 42 to provide additional shock absorption during impact.
The first edge 54 of the elongated body 74 can be oriented orthogonal to the second edge 56 thereof via a curved section 84 of the elongated body 74. During use, the curved section 84 of the elongated body 74 can be configured to lie adjacent to the upper edge of the panel 30 via a semi-circular channel 86 oriented along the length of the elongated body 74. As can be seen by reference back to
In contrast to the sill 36, which may be formed from a relatively hard material such as high-density polyethylene (HDPE), the soft cap 42 can be fabricated from a soft material having a lower indentation hardness to provide better absorption during impact. The term “soft” as used herein generally indicates a material having a shore durometer lower than 90-100 Shore A. In certain embodiments, for example, the material used to form the soft cap 42 can include a low-density polyethylene material having a durometer of about 60-30 Shore A whereas the material forming the sill 36 and other components of the dasher board assembly can have a durometer of about 90-100 Shore A or greater. The material used in forming the soft cap 42 will typically have a hardness sufficient to withstand cuts from the players' skates and to withstand repeated strikes without permanently deforming.
The first side 100 of the elongated body 94 can include a first curved section 104 forming a first edge 106 that extends along the length of the body 94. The second side 102, in turn, can include a second curved section 108 forming a second edge 110 that extends along the length of the body 94. A number of semi-circular channels 112,114 oriented along the length of the elongated body 94 can be provided to allow the curved sections 104,108 to bend or flex about the upper edges of the frame assembly.
In those dasher board systems where supported shielding panes are employed, or in portions of the dasher board where shielding panes are not present, the soft cap 92 can be configured to overly the entire upper periphery 38 of the frame assembly 14, forming a soft surface which acts to displace and absorb player impact. In the illustrative dasher board assembly 120 of
Although the soft cap 92 in
In some embodiments, one or more layers of harder material can be formed over all or a portion of the soft cap 92 to prevent scuffing and/or cutting of the soft cap 92 material during use. As shown in
Fabrication of the soft caps described herein can be accomplished using any number of suitable manufacturing methods such as injection molding, compression molding, transfer molding, or extrusion molding. While thermoplastic materials such as low-density polyethylene can be used to fabricate the soft caps, it should be understood that other types of moldable and/or extrudable materials can also be used to fabricate the caps, if desired.
In certain embodiments, the structure of the soft caps, including the orientation of the absorption ribs and channels, can be formed as a continuous piece of extruded material that can be later cut to a particular length, as needed, In one such embodiment depicted in
