Definitions
- 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.

- 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.
- 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.
- 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.
- 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.

Abstract
Soft caps for absorbing player impact against dasher boards are disclosed. The soft cap can include an elongated body defining a number of absorption ribs and channels for absorbing impact forces against the dasher board. The elongated body can be formed from a material having a relatively low durometer adapted to displace and absorb the impact energy when a player strikes the dasher board. One or more curved sections of the elongated body can be configured to fit adjacent to the hard edges of the dasher board. 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.
Description
- 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.
- Dasher 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.
- The 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.

soft cap 42 can be configured to cover theupper periphery 38 of theframe assembly 14 adjacent to the impact side of the shieldingpanes first edge 54 of thesoft cap 42 can be configured to overhang a portion of theimpact panel 30, as shown, forming a bumper to cover the hard edges of thepanel 30 during an impact. Asecond edge 56 of thesoft cap 42, in turn, can be configured to engage the impact side of the shieldingpanes panes second edge 50 of thesill 36. In some embodiments, the slot orU-shaped support channel 46 can be spring loaded against thesecond edge 56 of thesoft cap 42 to provide additional shock absorption during impact. -
FIG. 3 is a side cross-sectional view of thedasher board assembly 12 along line 3-3 inFIG. 1 . As shown further inFIG. 3 , theframe assembly 14 can further include a number ofvertical posts 58 each connected or welded at a lower end thereof to a lower base plate orbottom channel 60 anchored into the playingsurface 28 viabolts 62. The upper ends of theposts 58, in turn, are connected to severalupper stringers welding plate 68. A number ofadditional stringers vertical posts 58 adjacent to thepanel 30 to provide additional structural support to theframe assembly 14, if desired. Several holes oropenings 74 can be provided in thevertical posts 58 to permit an adjacent dasher board assembly to be fastened together in an end-to-end manner so as to define a bounded enclosure such as a hockey rink or soccer arena. -
FIGS. 4-5 are perspective views showing thesoft cap 42 ofFIG. 1 in greater detail. In the illustrative embodiment depicted, thesoft cap 42 comprises anelongated body 74 having afirst end 76, asecond end 78, afirst side 80, and asecond side 82. Thesides elongated body 74 may be oriented in a direction along a general longitudinal axis L of theelongated body 74 which, when assembled to the dasher board, are adapted to lie substantially parallel to theupper periphery 38 of theframe assembly 14. - The
first edge 54 of theelongated body 74 can be oriented orthogonal to thesecond edge 56 thereof via acurved section 84 of theelongated body 74. During use, thecurved section 84 of theelongated body 74 can be configured to lie adjacent to the upper edge of thepanel 30 via asemi-circular channel 86 oriented along the length of theelongated body 74. As can be seen by reference back toFIG. 3 , for example, thesemi-circular channel 86 permits thecurved section 84 of theelongated body 74 to bend or flex about the upper edge of thepanel 30, which, during impact, helps to distribute the impact forces over a wider area. -
FIG. 6 is a bottom plan view showing the bottom of thesoft cap 42 in greater detail. As can be further seen inFIG. 6 , theelongated body 74 may further define a number ofabsorption ribs 88 which act to further absorb forces exerted on the dasher board when struck by a player. Theribs 88 can be spaced apart from each other via a number ofchannels 90 that can be oriented lengthwise in a direction transverse to the general longitudinal axis L of theelongated body 74. The width W1 of theribs 88 as well as the width W2 of thechannels 90 can be selected so as to impart a desired amount of flexibility to theelongated body 74. In certain embodiments, for example, theribs 88 may have a width W1 of about ¾″ whereas thechannels 90 may have a width W2 of about 1″. It should be understood, however, that the dimensions of theribs 88 andchannels 90 can be varied to impart a different flexibility characteristic to thesoft cap 42. - In contrast to the
sill 36, which may be formed from a relatively hard material such as high-density polyethylene (HDPE), thesoft 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 thesoft cap 42 can include a low-density polyethylene material having a durometer of about 60-30 Shore A whereas the material forming thesill 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 thesoft cap 42 will typically have a hardness sufficient to withstand cuts from the players' skates and to withstand repeated strikes without permanently deforming. -
FIGS. 7-8 are perspective views showing another illustrativesoft cap 92 for use with acrylic dasher board systems or for portions of the dasher board without shielding panes. In the illustrative embodiment depicted inFIGS. 7-8 , thesoft cap 92 can comprise anelongated body 94 having afirst end 96, asecond end 98, afirst side 100, and asecond side 102. Thesides elongated body 94 which, when assembled to the dasher board, lies substantially parallel with the upper periphery of the lower frame assembly. - The
first side 100 of theelongated body 94 can include a firstcurved section 104 forming afirst edge 106 that extends along the length of thebody 94. Thesecond side 102, in turn, can include a secondcurved section 108 forming asecond edge 110 that extends along the length of thebody 94. A number ofsemi-circular channels elongated body 94 can be provided to allow thecurved sections -
FIG. 9 is a bottom plan view showing the bottom of thesoft cap 92 in greater detail. As can be further seen inFIG. 9 , theelongated body 94 may further define a number ofabsorption ribs 116 which act to further absorb forces exerted on the dasher board when struck by a player. Theribs 116 can be spaced apart from each other via a number ofchannels 118, which may be oriented lengthwise in a direction transverse to the general longitudinal axis L of theelongated body 94. As with other embodiments herein, the width W1 of theribs 116 as well as the width W2 of thechannels 118 can be selected so as to impart a desired amount of flexibility to theelongated body 94. In certain embodiments, for example, theribs 116 may have a width W1 of about ¾″ whereas thechannels 118 may have a width W2 of about 1″. Other dimensions are possible, however. -
FIG. 10 is a side cross-sectional view showing the illustrativesoft cap 92 ofFIGS. 7-9 attached to adasher board assembly 120 without shielding panes. Thedasher board assembly 120 may be similar to that described above with respect toFIGS. 1-3 , with like elements labeled in like fashion in the views. For example, thedasher board assembly 120 can include alower frame assembly 14 having a lower section attached to the playingsurface 28 via a number ofbolts 62, and a number ofvertical posts 58 connected to severalupper stringers welding plate 68. Other features such asadditional stringers openings 74 can be further provided, if desired. - 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 entireupper periphery 38 of theframe assembly 14, forming a soft surface which acts to displace and absorb player impact. In the illustrativedasher board assembly 120 ofFIG. 10 , thesoft cap 92 is shown overlying an existingsill 122 connected to theframe assembly 14. In contrast to the existingsill 122, which may be made from a relatively hard material such as high-density polyethylene (HDPE), thesoft cap 92 can be fabricated from a relatively soft material such as low-density polyethylene which acts to absorb more energy during an impact. In certain embodiments, for example, thesoft cap 92 can be formed from low-density polyethylene material having a durometer of about 60-30 Shore A whereas the existingsill 122 may be formed from a high-density polyethylene material having a durometer of about 90-100 Shore A or greater. The materials used to form thesoft cap 92 may vary, however, depending on the level of absorption desired, manufacturing considerations, as well as other factors. - Although the
soft cap 92 inFIG. 10 is shown overlying an existingsill 122, other embodiments in which thesoft cap 92 is adapted to fit underneath an existing sill, or alternatively is configured to fit onto a dasher board without an existing sill are also contemplated. When installed underneath an existing sill, for example, thesoft cap 92 can be configured to provide additional impact absorption while also reducing damage to the material resulting from the skaters' blades being pushed against the top surface of thecap 92. - 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 thesoft cap 92 material during use. As shown inFIG. 10 , for example, alayer 123 of material can be formed over the outer portion of thesoft cap 92 that is generally harder than the material forming thesoft cap 92. In certain embodiments, for example, thelayer 123 can include a layer of high-density polyethylene (HDPE) having a hardness that is greater than the material forming thesoft cap 92, which can comprise a low-density polyethylene. - 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
FIG. 11 , for example, asoft cap 124 for use in some supportless dasher board systems can include a number of longitudinally orientedabsorption ribs 126 to facilitate extrusion of thecap 124 as a single, continuous piece via an extruder. Thesoft cap 124 can comprise, for example, anelongated body 128 having afirst end 130, asecond end 132, afirst side 134, and asecond side 136. Theribs 126, which are spaced apart viachannels 138, may be oriented lengthwise in a direction along a general longitudinal axis L of theelongated body 128. In contrast to transversely oriented ribs, the longitudinally orientedribs 126 provide a degree of symmetry along the length of theelongated body 128, allowing thesoft cap 124 to be extruded as a continuous piece of material. -
FIG. 12 is a perspective view showing another illustrativesoft cap 140 having longitudinally oriented absorption ribs. Thesoft cap 140, which is configured for dasher board systems employing supported shielding panes or no shielding panes, can include a number of longitudinally orientedabsorption ribs 142 to facilitate extrusion of thecap 140 as a single, continuous member via an extruder. Thesoft cap 140 can comprise, for example, anelongated body 144 having afirst end 146, asecond end 148, afirst side 150, and asecond side 152. Theribs 142, which are spaced apart viachannels 154, may be oriented lengthwise in the direction of a general longitudinal axis L of theelongated body 144. Similar to the embodiment ofFIG. 1 , the symmetry of theelongated body 144 along its length allows thesoft cap 140 to be extruded as a continuous piece of material. - Having thus described the several embodiments of the present invention, those of skill in the art will readily appreciate that other embodiments may be made and used which fall within the scope of the claims attached hereto. Numerous benefits of the invention covered by this document have been set forth in the foregoing description. It will be understood that this disclosure is, in many respects, only illustrative. Changes may be made in details, particularly in matters of shape, size and arrangement of parts without exceeding the scope of the invention.
