DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

[0011] As discussed above, embodiments of the present invention relate to an on-demand shock stiffening system. The on-demand shock stiffening system operates to immediately stiffen the shocks in response to a user activating the system.

[0012] As shown in FIG. 1, the on-demand shock stiffening system 10 may be coupled to a hydraulic shock system 32 of a vehicle. The hydraulic shock system 32 may typically include a shock 26, a bridge 28 coupled to the shock 26, and an oil reservoir 30, wherein the oil reservoir 30 is coupled to the bridge 28 in order to supply oil to the shock 20. A main body 12 of the shock stiffening system 10 is coupled between the oil reservoir 30 and the bridge 28. The system 10 may be coupled to any hydraulic shock system and operate to stiffen any shock of the hydraulic shock system in an on-demand manner.

[0013] As shown in FIGS. 2A and 2B, the shock stiffening system 10 may include a main body 12 having an oil flow aperture 20 extending through the main body 12. Additionally, there are bypass apertures 22 that extend through the main body 12. The system 10 may include a flow control system that operates to stop the flow of oil through the oil flow aperture 20. In one embodiment, the flow control system includes a solenoid 14 coupled to a plunger 24. The plunger 24 is slidably coupled within a plunger channel 34 of the main body 12. The solenoid 14 is coupled to a control switch 18, which may be coupled to the vehicle within the driver compartment, by a coupler 16, which may be a wired coupler or a wireless coupler. The solenoid 14 is electric and is operable by operation of the control switch 18 that supplies power to the solenoid 14. The control switch 18 may be, without limitation, a push button. Activation of the solenoid 14 moves the plunger 24, within the plunger channel 34, to an engaged position that blocks flow of the oil between the reservoir 30 and the shock 26 through the bridge 28. The restriction of flow of oil through the oil flow aperture 20 prevents the shock 26 from compressing and keeps the shock 26 stiff or rigid.

[0014] With the restriction of flow of oil through the oil flow aperture by the plunger 24 being in the engaged position, pressure build up in the system can be an issue. The bypass oil apertures 22 are provided to allow oil to flow through the bypass apertures 22 in the event that the pressure of the oil reaches a predetermined level that requires flow through the bypass apertures 22. Deactivating the control switch 18 deactivates the solenoid 14 and the plunger 24 is moved to a disengaged position not blocking the oil flow aperture 20.

[0015] FIG. 3 is a block diagram of steps of a method 40 of using the on-demand shock stiffening system 10, which may include two subroutines of engaging flow restriction and disengaging flow restriction. The method 40 for engaging flow restriction may include engaging a control switch [Step 42]; engaging a flow control system in response to engaging the control switch [Step 44]; restricting oil flow between a vehicle shock and an oil reservoir in response to engaging the flow control system [Step 46]; and stiffening the vehicle shock in response to restricting oil flow between the vehicle shock and the oil reservoir [Step 48] The method 40 for disengaging flow restriction may include disengaging the control switch [Step 50]; disengaging the flow control system in response to engaging the control switch [Step 52]; allowing oil flow between the vehicle shock and the oil reservoir in response to engaging the flow control system [Step 54]; and reducing stiffness of the vehicle shock in response to allowing oil flow between the vehicle shock and the oil reservoir [Step 56]. While the flow control system is depicted as a solenoid 14 with a plunger 24, it will be understood that any type of flow control system may be utilized so long as the system restricts flow of oil between the reservoir 30 and the shock 26 in response to operating the control switch 18.
