Abstract
Shock absorbing corners for door-opening sections and doors of sport arena dasher board assemblies designed for initial installation or retrofitting are disclosed. The shock absorbing corners are specifically designed for player and penalty box areas. Their main purpose is to lessen player injuries by displacing and absorbing impact energy from body checks or falls into the exposed narrow and hard frame-side as well as the exposed hard and sharp corner of lower-frame door-opening sections and doors when the doors are opened or accidently become open during play, if the door latching mechanism is not fully engaged or becomes dislodged.
Description
TITLE: SHOCK ABSORBING CORNERS FOR DOOR-OPENING SECTIONS AND DOORS OF DASHER
BOARD ASSEMBLIES
FIELD OF THE INVENTION
The present invention relates to the field of dasher boards and accessories for use in bounded sports arenas such as hockey, box lacrosse and soccer. More specifically, the present invention pertains to shock absorbing corners for absorbing player impact against the exposed narrow hard frame-side and exposed hard-sharp corner of player and penalty box door-opening sections and doors of dasher board assemblies when doors are open or become open during play.
BACKGROUND OF THE INVENTION
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 from player impact. In the player and penalty box areas, dasher boards are designed with door openings to permit players to enter and exit the playing field. 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 checked into the boards throughout the course of a game. However, the present design of dasher boards for the player and penalty box areas can possess a significant injury risk situation during play when the player or penalty box door is opened or accidently become open during play, if the door latching mechanism is not fully engaged or becomes dislodged. In this situation, if players are checked or fall into the player or penalty box door-opening section, impact can occur against the exposed narrow and hard frame-side and exposed hard and sharp corner of the dasher board door-opening sections or doors which can result in serious player injury.
A typical hockey rink has two player boxes, one for each team and a penalty box with separate sections for opposing players. A typical dasher board assembly for the player and penalty box areas of a hockey rink includes lower-framed sections on each side of the player and penalty box doors, which swing inward from the playing surface. Each player box area would have two lower-framed dasher board doors, one at each end for entering and exiting the playing field during play or at a stoppage of play. The penalty box area would also have two lower-framed dasher board doors, one for each team that are used for entering during a stoppage of play or exiting either during play or at a stoppage of play. The lower-framed dasher board assemblies on each side of the doors typically have an anchoring system for attaching the lower frame to the rink surface. The dasher boards are typically fabricated in demountable sections of various lengths no greater than eight feet that are assembled together in an end-to-end fashion to form the boundary. The lower-framed dasher board doors are of similar design to that of the lower-framed dasher boards, except instead of being anchored, have a hinge and latching mechanism to permit inward swinging.
The front-outer surfaces of the lower-framed dasher boards and doors are typically made from hard materials such as high-density polyethylene (HDPE) or fiberglass which are not absorptive.
The side and corner of player and penalty box door-opening sections and doors of dasher board assemblies reveal an exposed narrow and hard frame typically being aluminum, steel or wood and the exposed hard and sharp corner edge of the front-outer surface.
There have been recent design improvements focused on imparting greater flexibility and absorption capabilities of dasher boards in order to dampen the significant impacts that can occur during play. These improvements have focused on increasing the flexibility of the main outer arena sections to allow for displacement of the dasher board in response to an impact by .. incorporating loose anchors and bolts, spring-mounted systems and aluminum frames.
These improvements, however, have not specifically provided any greater flexibility and absorption capabilities for the player and penalty box door-opening sections or doors of dasher board assemblies when doors are opened or become open. Due to the more aggressive playing style and faster speeds associated with contact sports such as hockey that have resulted in serious player injury at arena door-opening sections, there is an ongoing need in the art for dasher boards specific to the player and penalty box door-opening sections and doors to having shock absorption features that lessen player impact and injuries.
SUMMARY OF THE INVENTION
The present invention relates generally to SAFE 90 CORNER's for absorbing player impact against the exposed narrow and hard frame-side as well as the exposed hard and sharp corner of dasher board and door assemblies in the player and penalty box areas when the player or penalty box door is opened or accidently become open during play, if the door latching mechanism is not fully engaged or becomes dislodged.
A SAFE 90 CORNER for use with a lower-frame dasher board and door can include a shock absorbing corner vertical core section formed from a solid polymer material adapted to displace and absorb the impact energy when a player strikes the side and corner of the dasher board door-opening section or door in the player or penalty box area. The specifications of the corner vertical core section can be approximately three inches to six inches in width, three inches to five inches in depth and thirty to forty inches in height depending upon the actual lower-framed dasher board and door assembly measurements that vary amongst arenas. The polymer material can have a durometer of about 60-80 on the Shore 00 scale or 10-40 on the Shore A scale for the vertical core section. The core section can be of one solid piece of the same hardness or layered-pieces of different hardness's within the durometer ranges specified above. A harder plastic backing of about 60-70 on the Shore D scale can also be bonded to the vertical core section with screw inserts for attachment to the lower-frame dasher board and door.
The front-impact outer-surface of the shock absorbing corner vertical core section facing the ice-surface can be constructed of a hard-plastic polymer being HDPE, polyurethane or similar material.
The design can be of a singular or individual sectional hard-plastic polymer pieces with a

SUMMARY OF THE INVENTION
The present invention relates generally to SAFE 90 CORNER's for absorbing player impact against the exposed narrow and hard frame-side as well as the exposed hard and sharp corner of dasher board and door assemblies in the player and penalty box areas when the player or penalty box door is opened or accidently become open during play, if the door latching mechanism is not fully engaged or becomes dislodged.
A SAFE 90 CORNER for use with a lower-frame dasher board and door can include a shock absorbing corner vertical core section formed from a solid polymer material adapted to displace and absorb the impact energy when a player strikes the side and corner of the dasher board door-opening section or door in the player or penalty box area. The specifications of the corner vertical core section can be approximately three inches to six inches in width, three inches to five inches in depth and thirty to forty inches in height depending upon the actual lower-framed dasher board and door assembly measurements that vary amongst arenas. The polymer material can have a durometer of about 60-80 on the Shore 00 scale or 10-40 on the Shore A scale for the vertical core section. The core section can be of one solid piece of the same hardness or layered-pieces of different hardness's within the durometer ranges specified above. A harder plastic backing of about 60-70 on the Shore D scale can also be bonded to the vertical core section with screw inserts for attachment to the lower-frame dasher board and door.
The front-impact outer-surface of the shock absorbing corner vertical core section facing the ice-surface can be constructed of a hard-plastic polymer being HDPE, polyurethane or similar material.
The design can be of a singular or individual sectional hard-plastic polymer pieces with a
- 2 -durometer of about 60-70 Shore D that is like the hardness of current dasher boards to withstand body-checking and puck deflection. The hard-plastic polymer can be bonded to the shock absorbing corner vertical core section to deflect inward upon impact, thus eliminating the hard-solid corner.
The top edge of the shock absorbing corner vertical core section can be constructed of the same solid polymer material having a durometer of about 60-80 on the Shore 00 scale or 10-40 on the Shore A scale with a rounded corner profile. It would be designed to displace and absorb the impact energy when a player strikes the top edge section of the dasher board door-opening section or door in the player or penalty box area.
To incorporate the shock absorbing corner assembly into the player and penalty box dasher board sections and doors, the outer-corner section of the board and door can be designed with mechanical structural modifications for initial arena installations or retrofitting. Specifically, the dasher board and door assemblies can be modified to not include a front-corner frame section, thus providing the required spacing to recess the SAFE 90 CORNER in its place.
To reinforce the frame, a corner support brace can be mechanically-fastened and/or welded in place.
Having thus described 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 description hereto.
Numerous benefits of the invention covered by this document have been set forth in the forgoing background and description. It will be understood that this disclosure is, in may 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.
