Definitions

  • This invention is directed to a racquetball and squash court and more particularly to an improved racquetball and squash court wall panel construction which will withstand wide fluctuations in humidity and temperature.
  • a typical racquetball court has four vertical walls.
  • the court dimensions are 40' long by 20' wide by 20' high.
  • the sidewalls require 800 square feet of paneling or a combination of twenty-eight 4' x 8' and 4' x 4' panels.
  • These panels are butted together with the edges either erfed for tongue and groove, lap joints, or aluminum spline. These processed edges allow the panels to be installed on studs or furring by use of screws with the screws embedded into the core of the panels so that when the next panel is slotted against the adjoining panel, the screws are covered up inside the panel.
  • a bead of adhesive is applied on each furring strip or stud. The screws basically align the panels and hold the individual panels onto the studs or furring until the structural adhesive dries.
  • wet wall or plaster courts are the constant cracking and peeling of the plaster type surfaces. These require continual patching and painting in order to keep the courts in reasonable condition. After several years, the wet wall systems always look old and worn which is undesirable, especially in clubs and college situations. Wet wall or plaster type courts are also extremely noisy which has contributed to their decline over the years.
  • a standard 4' x 8' and 4' x 4' particle board panel heretofore accepted for constructing racquetball and squash courts, has been constructed with an ability to withstand wide fluctuations in humidity and temperature.
  • a standard particle board panel has been used onto which a specially selected wood style has been glued around its edges. This is accomplished in part by applying a wood style around industrial particle board in conjunction with the application of a special moisture resistant seal. Applying phenolic plastic laminate to both faces of the core overlapping the wood piece thus encapsulating the particle core so moisture can not penetrate to the particle board.
  • the wood edges are conventionally routed and squared for tongue and groove installation.
  • the moisture resistant seal consists of phenolic plastic laminate glued to the edge of the wood style which is next to the particle board edge.
  • the wood style consists of a type of wood that resists expansion when moisture is absorbed.
  • the key feature of this invention is that when moisture is absorbed in the panel, only the wood edges 1- 1/2" deep around the panel can expand because of the moisture resistant seal.
  • the style without the moisture resistant seal will perform adequately.
  • the moisture resistant seal is recommended. Moisture can penetrate the wood style, especially when humidity exceeds 80%. This diffusion process will allow moisture to travel into the particle board core if the phenolic moisture resistant seal were not in place.
  • the moisture would be contained by the wood style and would not reach the particle board core with or without the phenolic moisture resistant seal.
  • the moisture resistant seal also ensures integrity in the case of high moisture other than humidity - such as water leaks.
  • Another object is to provide a method and panel system whereby standard 4' x 8' and 4' x 4' accepted racquetball and squash panels are constructed such that they have an ability to withstand wide fluctuations in humidity and temperatur .
  • Still another object is to provide a racquetball and squash court which has a neat appearance and one which will retain its neat appearance over a long period.
  • While another object is to provide a wall panel construction for a racquetball and squash court which can be installed without the requirement for a prior construction of a HVAC system.
  • Another object is to provide a panel system for a racquetball and squash court wherein less expensive material may be used for the panels.
  • Another object is to provide a panel construction system such that the panels need not be shipped to the job site before actual construction starts.
  • Fig. 1 illustrates a particle board made in accordance with this invention with portions removed to expose other portions
  • Fig. 2 is an enlarged cross sectional view along 2-2 of Fig. 1 cut through the core material to shorten the drawing;
  • Fig. 3 illustrates a side wall elevation of a racquetball or squash court made with panels according to this invention.
  • Fig. 4 illustrates a partial view of a side wall and front wall with a structure to which the panels are secured.
  • Fig. 5 is a partial cross sectional view through Fig. 4 along lines 5-5 illustrating the panels secured to the supports.
  • FIG. 1 a particle board panel, with portions removed made in accordance with this invention.
  • finished panels are both 4' x 8' and 4' x 4'.
  • a particle board core 12 which may be made of Southern pine having the dimension of about 46 1/2" by 94 1/2".
  • the thickness of the core may vary between 1", 3/4" or 1/2" to provide a finished thickness of 1 1/8" for a front wall, 7/8" for a side and back wall and 5/8" for the ceiling.
  • the core material 12 consists of a standard 45 lb. or 60 lb. industrial grade particle board. Before construction of the panel, the moisture content of the core material should be 5% ⁇ 1%. Wood strips 14 are made of catalpa wood or northern white cedar installed around the edges of the particle board core. These wood strips are selected for this purpose because of their resistance to expansion, once moisture has been introduced, as will be explained in greater detail in later paragraphs. The wood strips should be cut to approximately 1 1/2" wide and by the proper length depending on whether the finished size is 4' x 4' or 4' x 8' long and depending on which edge of the core the strips are to be applied.
  • a phenolic laminate or moisture resistant seal 16 needs to be applied to the edge of the wood strip that is to be installed against the particle board core or to the edge of the particle board core.
  • the thickness of the laminate is typically 0.050 phenolic plastic laminate supplied by companies like Formica Corporation.
  • the phenolic moisture resistant seal can be edge-banded to the wood strip using a typical hot melt process. This process laminates the phenolic strip to the edge of the wood strip and trims it flush to both sides of the wood strip at the same time. Once the phenolic strips are installed on the edges of the wood strips, these now edge-laminated styles can be glued and clamped on all four surrounding edges of the particle board core. The phenolic edge must be in contact with the particle board core.
  • the panels After sanding, the panels are run through a Black Brothers Glue Spreader applying urea formaldehyde glue approximately five to seven mils thick on both sides of the core and wood strips. After applying glue to both faces of the panels, a sheet of plastic laminate 18 is then applied to both faces of the panel .
  • the panels are stacked and moved into a hydraulic press. The panels will stay pressed under 60 lbs. per square inch pressure for approximately one hour. After removal from the press, all four edges will be machined through the double end tennenor. This machine trims the edges, adding the tongue 20 and groove 22 and squaring the panel to ⁇ 1/32".
  • the finished panel After the edges are routed, the finished panel has approximately 1" of wood strip around all edges so that moisture must travel through the wood strip before reaching the phenolic moisture resistant seal. Because of the special moisture resistant seal, moisture would not be able to penetrate to the porous particle board core. This is one key in the development of this new panel.
  • FIG. 3 illustrates the steel wall support structure. It is obvious that in order to have straight end walls, some of the panels must be made in 4' x 4' dimensions in order to set the panels alternating in adjacent rows and to have a smooth edge on opposite ends of the wall.
  • the thickness swell under the same conditions would be 0.1875 inches.
  • the particle board expanded over thirty times greater than the catalpa wood during the same test. Even though this is true, it is even more significant that the moisture, if it does penetrate the wood strip, can only effect the first 1 1/2 " because of the phenolic moisture resistant seal.
  • moisture once moisture is introduced into a standard particle board panel, it can travel throughout the entire eight foot panel very rapidly. It has been determined that completed panels using standard, prior art procedures, subjected to extreme humidity will continue to expand or move until permanent damage occurs on the racquetball court walls. However, the panel of this invention withstands this high humidity with little or no damaging effect.
  • This new panel has many features, one of which is that each panel will be able to resist expansion due to humidity fluctuations within the environment. No longer will this moisture absorption occur, thereby eliminating very costly damage to the racquetball and squash court walls.
  • each panel has the ability to resist moisture absorption, the entire wall will not move as one unit. This is currently not the case with standard panels. All of the prior art panels expand together as a unit applying pressure upon each other which causes cupping and warping at the seams. In the new panel, only the outer 11/2" could be effected by moisture. The expansion of the wood style is not enough to cause damage to the panel. Even if moisture travels through the wood style, the phenolic moisture resistant seal will stop moisture from entering the particle board core.
  • the new wall system can be installed in a non- controlled environment.
  • the typical wall panels must be installed in a controlled environment of 40% to 60% humidity and 65 to 78 degrees. These new panels can be installed within a 10% to 90% humidity level with 40 to 95 degree temperatures. This means that the courts can be installed prior to the operation of an HVAC system and therefore does not delay the project.
  • the air conditioning units cannot be turned on until the building is finished, and the wall system cannot be installed until the air conditioning is turned on. This new panel solves this major problem. Many times the buildings do not have the proper amount of insulation or have the wrong HVAC systems, which usually shows up during the high humidity season and results in damaged panels.
  • the core is a Western Ponderosa Pine.
  • a less expensive Southern Pine is not used in the core because of its tendency to absorb moisture quicker than its Western counterpart.
  • One important feature of this invention is that it incorporates standard, accepted racquetball and squash court panel materials that are currently being marketed today. Over 90% of all courts built world wide today use a plastic laminated particle board panel. It is important that any new panel use materials in accordance with the present invention.
  • An important part of this invention is the dual aspects in which the panel can be constructed. If, prior to the installation of the new panel in a building, the humidity is known not to exceed the parameters of 30% to 80%, then the phenolic moisture resistant seal could be used but is not required. If however, the humidity could exceed these parameters to a maximum limit of 10% to 90% humidity level, then it would require the phenolic moisture resistant seal. Not incorporating the phenolic moisture resistant seal within the panel would save money in manufacturing; however, incorporating the phenolic moisture resistant seal would insure a panel that would not expand in high humidity situations.

Abstract

Procédé et panneau améliorés permettant de construire des murs de court de squashs et de tennis, ledit panneau (10) étant construit de manière à posséder des caractéristiques lui permettant de supporter de fortes variations de température et d'humidité. On obtient ce résultat en appliquant un joint l'étanchéité au phénoplaste stratifié ou résistant à l'humidité autour des côtés extérieures de la partie centrale (12) d'un panneau de particules utilisé dans la construction, puis en appliquant une bordure en bois (14) autour des bords extérieurs des côtés recouverts de phénophaste stratifié de la partie centrale (12) du panneau de particules. Il est ensuite nécessaire d'appliquer une feuille de plastique stratifié (18) sur les deux faces de la partie centrale (12) du panneau de particules, qui recouvre les bordures en bois (14) et qui encapsule aussi la partie centrale du panneau de particules de sorte que l'humidité ne peut y pénétrer. Les bords des bordures sont détournés et découpés à angles droits de manière classique pour permettre une installation du type à fausse languette comprenant une languette (20) et une rainure (22).
