Definitions

  • the present invention relates to an eyeglass lens cleaning apparatus comprising a housing with two protruding arm sections having rotatable heads, at least one drive unit, an energy source, a shaft arrangement, where said housing is provided with said drive unit and said energy source, where said shaft arrangement comprises a longitudinal shaft provided inside said arm sections, each of said longitudinal shaft provided with gear means adapted to transfer the rotating movement from said drive unit to said rotatable heads, which are movably and exchangeably arranged on an axis approximately perpendicular to said longitudinal shafts and provided with polishing means adapted to be pressed against opposite sides of an eyeglass lens.
  • the present invention relates to polishing means for use with the aforementioned eyeglass lens cleaning apparatus.
  • the eyeglass lens cleaner for cleaning e.g. monocles.
  • the eyeglass lens cleaner is formed as a U-shaped clip provided with exchangeable polishing pads at the end parts positioned opposite each other.
  • US 5,222,268 describes a pocket eyeglass lens cleaning apparatus, which is formed as a U-shaped clip provided with a rotating polishing pad and a stationary polishing pad at the end parts.
  • the polishing pads are positioned opposite each other.
  • the pocket eyeglass lens cleaning apparatus comprises a battery and an electrical motor for operating the rotating polishing pad, which reduces the number of hand movements necessary for polishing the eyeglass lenses.
  • FR-A1 -2,750,223 describes an eyeglass lens cleaning apparatus, which is formed with a housing with two protruding arm sections having rotatable heads, two electrical motors and a battery.
  • This eyeglass lens cleaning apparatus is unmanageable, because the electrical motors are placed in direct connection to the rotatable head and inside the two protruding arm sections. This causes the eyeglass lens cleaning apparatus to be bulky around the rotatable heads, which is a disadvantage when polishing small spectacles.
  • a further disadvantage is that the eyeglass lens cleaning apparatus has fixed arm sections, which do not allow any part of the apparatus to be exchanged, except for the rotatable heads. This means that the flexibility of the apparatus is reduced and it is necessary to buy a new apparatus in case any of the arm sections are damaged.
  • DE-U1-89 03 613 describes an eyeglass lens cleaning apparatus, which is formed with a housing with two protruding arm sections having rotatable heads, one centrally positioned electrical motor and two batteries, where both rotatable heads are driven by said electrical motor via a belt arrangement.
  • this pocket eyeglass lens cleaning apparatus has two springy arms inside the protruding arms for pushing the polishing pads together during the polishing process.

  • DE-A1-197 08 811 describes an eyeglass lens cleaning apparatus, which is shaped with a housing with two protruding arm sections having rotatable polishing heads and one centrally positioned electrical motor. Unfortunately, the description and the claim provide no technical details for the reader to use for understanding the described invention.
  • DE-U1-298 10 702 describes an eyeglass lens cleaning apparatus, which is formed with two arm sections each having a rotatable polishing head, an electrical motor and two batteries.
  • the motor transfers the rotation movement to the polishing head via a spindle arrangement.
  • a further disadvantage is that the eyeglass lens cleaning apparatus uses a spindle arrangement to transfer the rotating movement from the motor to the polishing pads.
  • a spindle arrangement is very sensitive to wear of the spindle and will not work properly if the spindle is worn down.
  • said gear means comprise a crankshaft part of said longitudinal shaft and a groove in said rotatable heads, and where said crankshaft part is fitted into said groove for the reciprocal movement of said polishing means
  • a further object of the present invention is to provide exchangeable polishing means.
  • polishing means as described in the preamble of claim 9, and wherein said polishing means, on a rear side, are provided with a protruding part with a recess, where said recess is adapted to engage with said bow part of said rotatable head.
  • the apparatus has simple gear means adapted to transfer the rotating movement from a drive unit to a rotatable head, said gear means comprise a crankshaft part of said longitudinal shaft and a groove in said rotatable heads, and where said crankshaft part is fitted into said groove for the reciprocal movement of said polishing means.
  • the crankshaft part of said longitudinal shaft rotates in a circle around the longitudinal axis of the longitudinal shaft.
  • the circle movement of the crankshaft part is prevented, and the crankshaft part follows the groove and move from side to side, hence the rotatable head performs the reciprocal rotatable movement, which is essential to efficient cleaning of an eyeglass lens.
  • the rotatable heads/polishing means are positioned opposite each other and that they rotate in opposite directions.
  • the forces resulting from the rotating movement on one side of the eyeglass lens from the first rotatable head is neutralized by an oppositely directed force as a result of the rotating movement on the other side of the eyeglass lens from the other rotatable head.
  • the spectacle frame is therefore not exposed to unnecessary strain.
  • the rotatable heads are adapted to operate in a mutual opposite reciprocal movement, ensuring that the polishing means almost rub stains, spots or grease away without moving the rotatable heads.
  • this method is better, as it is easier to remove a stain by rubbing it away with a reciprocal movement than by wiping it away with a circulating movement.
  • the gear means connecting the electrical motors to the rotatable heads ensures that the rotatable heads are operated in a mutual opposite reciprocal movement. Furthermore, the gear means provides an efficient power transfer from the motors to the rotatable heads, while the motors are placed in the housing and close to the battery.
  • said eyeglass lens cleaning apparatus furthermore, comprises activation means.
  • activation means being an internal switch, which is positioned inside the housing and connected to the arm sections, whereby a compression force, of a certain level, on the protruding arms activates the internal switch, whereby the energy source is brought in connection with the drive units.
  • said activation means are a switch, which is used to connect the energy source to the drive units, thereby starting the reciprocal movement of the rotatable heads.
  • the switch is positioned on one of the protruding arms in a position easy to operate while holding the apparatus in the hand.
  • the energy source is a battery, which provides electrical current to the drive units.
  • the battery can be a rechargeable battery or a disposable battery.
  • the energy source is a mechanical device such as a spring, which has to be wound up on a regular basis for providing the necessary force to rotate the rotatable heads.
  • said eyeglass lens cleaning apparatus furthermore, comprises a socket, which is adapted for connection to an energy charger.
  • the drive unit is an electrical motor, which is arranged for a reciprocal movement of the motor shaft.
  • the drive unit is a movement generating set, such as an electromagnetic appliance arranged for creating a reciprocal movement.
  • the arm sections are exchangeably connected to the housing.
  • the protruding arms are easily exchanged, if there is a problem with the gear means or if the polishing means on the rotatable heads are worn out.
  • the arm sections are flexible parts of the housing, which makes the housing an easy producible product e.g. by moulding.
  • said rotatable heads are provided with a protruding bow part at an end part, which protruding bow part preferably is arranged inside an opening, and said polishing means, on a rear side, are provided with a protruding part with a recess, where said recess is adapted to engage with said bow part of said rotatable head.
  • the recess and bow part connection make it easy to exchange the polishing means in case the polishing materials are worn out or in case another type of polishing means must be used to ensure efficient polishing of the eyeglass lenses.
  • the recess and bow part allows connection between the rotatable head and the polishing means, as the polishing means are able to tilt slightly in every direction in regard to the rotatable head, hence the efficiency of the polishing process increases, because it is possible for the polishing means to follow the curvature of an eyeglass lens.
  • joint connection could be a ball-and-socket joint or any kind of joint, which allows the rotatable heads to tilt in several directions.
  • the aforementioned embodiments of the inventions allow the manufacturer of the eyeglass lens cleaning apparatus to produce and sell a basic and full operational version of the eyeglass lens cleaner. Instead of throwing the entire apparatus away when the polishing means/polishing materials are worn out, the manufacturer provides the costumer with the possibility of buying new parts, e.g. polishing means with different types of polishing materials, rotatable heads of different diameters or sizes, or arm sections with different gear means.
  • the eyeglass lens cleaning apparatus is manufactured in a range of different types, e.g. a cheap and simple eyeglass lens cleaning apparatus adapted to be used and throw away when the polishing means/materials are worn out or an exclusive eyeglass lens cleaning apparatus with an appealing design and the possibility of changing the protruding arm sections, the cover section, the rotatable heads, the polishing means or the polishing materials.
  • the two protruding arm sections are flexible parts of said housing.
  • the flexibility of the protruding arms furthermore, ensures the possibility to fully polish both sides of the eyeglass lens despite the position of the nose pads or the bar connecting the two eyeglass rims of the spectacle frame.
  • the housing furthermore, comprises an elastic member which is adapted to withstand a compression force on the housing.
  • the elastic member is arranged in the housing and connected to the a m sections so it counteracts any force compressing the two protruding arms sections together, which causes the protruding arm section to be in a fixed position when the eyeglass lens cleaning apparatus is not in use.
  • the elastic member is an elastic rubber band connecting the end parts of the two protruding arms inside the housing.
  • the rubber band is arranged so it can be stretched, when a compression force is applied on the two protruding arms and then retracted to its original form, when the compression force on the two protruding arms is reduced.
  • the elastic member is any kind of a spring, connecting the end parts of the two protruding arms inside the housing.
  • the eyeglass lens cleaning apparatus furthermore, comprises a socket adapted for connection to an energy charger.
  • the eyeglass lens cleaning apparatus comprises a socket adapted for connection to an energy charger.
