Regarding claim 19, Nishizawa further discloses:
wherein the one or more dynamic stoppers automatically switch from the second position to the first position based on a door opening signal when the elevator car reaches a destination floor (in the automatic mode described on page 2, paragraph 10 through page 3, paragraph 3 and shown in figure 10 each stopper 63, 64 lowers from the raised second position to the lowered first position when a door opening signal is received for the respective door associated with the stopper).
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 9 and 11 are rejected under 35 U.S.C. 103 as being unpatentable over JP H11199162 A (Okada, Applicant’s cited prior art) in view of JP H0867466 A (Nishizawa).
Regarding claim 9, Okada teaches:
The elevator system of claim 3.
Okada does not teach:
wherein the front-end stopper operates in the second position and the rear-end stopper operates in the first position when the at least one trolley enters from the rear door, and wherein the front-end stopper and the rear-end stopper operate in the first position when the at least one trolley exits from the front door.
However, Nishizawa teaches:
An elevator system with front-end and rear-end stoppers (63, 64), and
wherein the front-end stopper (63) operates in the second position and the rear-end stopper (64) operates in the first position when the at least one trolley enters from the rear door (figure 10d), and wherein the front-end stopper and the rear-end stopper operate in the first position when the at least one trolley exits from the front door (with both front and rear doors 52, 53 open the car or trolley can exit the front door and both stoppers are in the first, lowered position).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to operate the elevator system of Okada in the process taught by Nishizawa so that the front end stopper is raised and the rear end stopper is lowered with a trolley enters from the rear door to avoid damage to stop the trolley in the correct position and avoid damage to the front door while allowing the trolley to roll past the rear end stopper, and have both stoppers lowered when exiting to allow trolley movement and prevent damage to the stoppers. Nishizawa notes on page 1 of the attached machine translation, paragraph [0002], lines 1-2, “an electric stopper is provided on the floor of the elevator car to prevent the vehicle from overshooting in order to protect the elevator car door.” Each respective stopper is in the first or second position during trolley movement to allow the movement of the trolley while protecting the elevator car doors.
Regarding claim 11, Okada teaches:
The elevator system of claim 3.
Okada does not teach:
wherein the front-end stopper operates in the first position and the rear-end stopper operates in the second position when the at least one trolley enters from the front door, wherein the front-end stopper and the rear-end stopper operate in the first position when the at least one trolley exits from the rear door.
However, Nishizawa teaches:
An elevator system with front-end and rear-end stoppers (63, 64), and
wherein the front-end stopper (63) operates in the first position and the rear-end stopper (64) operates in the second position when the at least one trolley enters from the front door (figure 10b), wherein the front-end stopper and the rear-end stopper operate in the first position when the at least one trolley exits from the rear door (with both front and rear doors 52, 53 open the car or trolley can exit the rear door and both stoppers are in the first, lowered position).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to operate the elevator system of Okada in the process taught by Nishizawa so that the rear end stopper is raised and the front end stopper is lowered when a trolley enters from the front door to avoid damage to stop the trolley in the correct position and avoid damage to the rear door while allowing the trolley to roll past the front end stopper. Nishizawa notes on page 1 of the attached machine translation, paragraph [0002], lines 1-2, “an electric stopper is provided on the floor of the elevator car to prevent the vehicle from overshooting in order to protect the elevator car door.” Each respective stopper is in the first or second position during trolley movement to allow the movement of the trolley while protecting the elevator car doors.
Claims 4-6, and 13 are rejected under 35 U.S.C. 103 as being unpatentable over JP H11199162 A (Okada, Applicant’s cited prior art) in view of JP 2009202996 A (Yano, Applicant’s cited prior art).
Regarding claim 4, Okada teaches:
The elevator system of claim 3.
Okada is silent to the configuration of the actuators.
However, Yano teaches:
An elevator system with two stoppers (22, 32) with respective actuators (20, 30), and
wherein the one or more actuators comprise a front-end actuator (electromagnetic actuator of 20) coupled to the front-end stopper and a rear-end actuator coupled to the rear-end stopper (electromagnetic actuator of 30), respectively.
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for each stopper of Okada to have a respective actuator as taught by Yano to enable individual control of each stopper. The ability to control each stopper individually allows the front-end stopper to be lowered while the rear-end stopper is raised so a wheeled trolley or wheelchair can move into the space between the stoppers while being prevented from moving beyond the rear-end stopper. Yano notes on page 3, paragraph 5, lines 4-6, “it is possible to prevent the carriage from colliding with the landing door and the car door when the carriage gets on and off, and accompanying the deformation of the landing door and the car door, and the deformation of the guide shoe of each door A door opening/closing failure can be prevented.”
Regarding claim 5, Yano further teaches:
wherein the front-end actuator (electromagnetic actuator of 20) and the rear-end actuator (electromagnetic actuator of 30) operate in an expanded position to articulate the front-end stopper and the rear-end stopper to the second position (coil spring 42 is in an expanded position to articulate 22 or 32 to the second, raised position as can be seen in figure 2, expansion of spring 42 raises 22).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to use the electromagnetic actuators of Yano in the elevator system of Okada with a reasonable expectation of success for the well-known benefits of energy efficiency and fast response times.
Regarding claim 6, Yano further teaches:
wherein the front-end actuator (electromagnetic actuator of 20) and the rear-end actuator (electromagnetic actuator of 30) operate in a retracted position to articulate the front-end stopper and the rear-end stopper to the first position (coil spring 42 is in a retracted position to articulate 22 or 32 to the first, lowered position as can be seen in figure 2, retraction of spring 42 lowers 22).
Regarding claim 13, Yano further teaches:
wherein each of the one or more actuators is coupled to an arm (arm, annotated figure 2) and the arm is installed on a flange (flange, annotated figure 2) connected to the platform (15).

Claims 10 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over JP H11199162 A (Okada, Applicant’s cited prior art) in view of US 20170320705 A1 (Honda).
Regarding claim 10, Okada teaches:
The elevator system of claim 1, wherein the command from each of the one or more control panels (9) is provided by an operator, wherein the operator presses a button (“stopper projection button” abstract, lines 5-6) on the one or more control panels.
Okada does not teach:
inserting a physical key and the button being a key switch button.
However, Honda teaches:
An elevator control panel, and
an operator inserting a physical key on the control panel (paragraph [0022], lines 8-10, “The evacuation guide turns a key to select “ON” with the key inserted in the key switch 9…”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to require a physical key to operate the stoppers of Okada, as taught by Honda, to prevent accidental deployment of the stoppers. Untimely deployment of the stoppers could result in injury of passengers, providing physical keys only to select operators ensures the stopper projection button is not accidentally activated.
Regarding claim 12, Okada and Honda further teach:
wherein the one or more dynamic stoppers (6a, 6b, Okada) switch from the first position to the second position when the key switch button (9, Honda) is operated by the operator.
Claim 16 is rejected under 35 U.S.C. 103 as being unpatentable over JP H11199162 A (Okada, Applicant’s cited prior art) in view of JP 2009202996 A (Yano, Applicant’s cited prior art) as applied to claim 5 above, and further in view of JP H0867466 A (Nishizawa).
Regarding claim 16, Okada and Yano teach:
The elevator system of claim 5.
Okada and Yano are silent to a command from one or more components that enable(s) the stoppers to operate in the second position.
However, Nishizawa teaches:
wherein the front-end actuator and the rear-end actuator operate in the expanded position (extended coil spring position of Yano) on receiving a command from the one or more components enabling the one or more dynamic stoppers to operate in the second position (the elevation motors are connected to control component 12 as shown in the diagram of figure 3, Nishizawa, page 6, paragraph 6, lines 3-5, “When the operation control unit 12 receives the OFF signal from the wheel detection sensor 4a, it outputs a door close command after a predetermined time, for example, the time required to stop the vehicle, closes the front car door 3a, and closes the door. In conjunction with this, the front electric stopper 2a is raised.”).
It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention for the actuators of Okada and Yano to operate in the expanded position upon receiving a command from a control component as taught by Nishizawa in order to prevent damage to the elevator car doors. Nishizawa teaches a control unit 12 that receives a signal from a wheel detection sensor that indicates the wheel is in a proper position and subsequently sends a command to close the associated elevator car door and simultaneously raise the associated stopper. This procedure prevents not only damage to the trolley, but also damage to the door. Nishizawa notes on page 1 of the attached machine translation, paragraph [0002], lines 1-2, “an electric stopper is provided on the floor of the elevator car to prevent the vehicle from overshooting in order to protect the elevator car door.”
