Definitions
- This invention relates to automobile convertible tops and, more particularly, to an operating mechanism for a convertible top having a movable rear bow.
- Power tops that utilize a movable rear bow normally provide a pair of cylinders to operate the top, and require manual operation to raise and lower the rear bow or provide an additional pair of cylinders to operate the rear bow.
- this invention comprises a convertible top operating mechanism which includes a bi-directional hydraulic pump which is selectively connected to top-operating hydraulic cylinders and tonneau-operating hydraulic cylinders by a two-way, 5-condition control valve to selectively raise and lower the top and tonneau.
- a mechanical linkage connects the top-operating cylinders with a movable rear bow and is co-operable with a spring during operation of the top-operating cylinders when fully extending and initially retracting to move the rear bow to enable tonneau operation and to seal the top on the tonneau.
- this invention comprises a vehicle having a convertible top movable between a lowered position stored in a storage well and a raised position, said storage well having a cover movable between open and closed positions, said top comprising a pair of spaced linkages each comprising a plurality of pivotally-interconnected side rails including a rear rail, a plurality of spaced transverse bows, including a rear bow pivotally attached to the rear rails for independent raising and lowering movement relative to the rear rail to enable movement of the cover, interconnecting the linkages to support a fabric top, and a power operator connected to each rear rail that is extensible to raise and retractable to lower the top.
- a top operating mechanism includes a drive pin is mounted on each rear rail.
- a slotted clevis having a drive abutment is mounted on the end of each actuator and embracing the drive pin, while a spring provides a lowering bias to the rear rail.
- a drive link pivotally mounted on each clevis is engageable with the drive pin during extension of the power operators to raise the top.
- a drive surface on each rear bow is engageable by the drive abutment to raise the rear bow, and a cam surface on the rear rail is engageable with the drive link when the top is raised to pivot the drive link out of engagement with the drive pin to enable the drive abutment to engage the drive surface to raise the rear bow upon further extension of the power operators.
- the power operators are hydraulic cylinders that are controlled by a 5- way (or condition), 2-position control valve which operate a bi-directional hydraulic pump. This valve is connected to both top-operating hydraulic cylinders and to a pair of tonneau-operating hydraulic cylinders.
- both ends of the top cylinders are connected to both sides of the pump, while one end of the tonneau cylinders are connected to one side of the pump, and the other tonneau cylinder ends are blocked.
- condition 1 When the pump is inoperative (condition 1), this allows the top to float, but secures the tonneau against movement.
- both ends of the tonneau cylinders are connected to both sides of the pump, while one end of the top cylinders are connected to one side of the pump and the other top cylinder ends are blocked. If this position were used when the pump is inoperative, the tonneau would be unpressured and float, while the top would be secured against movement; however this condition is not utilized.
- Figs 11 - 15 are schematic diagrams of a hydraulic system according to this invention, illustrating the sequence of operations for operating the top and tonneau.
- FIG. 1 - 7 show a portion of one side of a convertible top linkage.
- a vehicle body bracket 20 pivotally mounts a rear rail 22 that includes a bracket 24 that pivotally mounts a movable rear or #5 bow 26 that is movable relative to rear rail 22 between raised and lowered positions.
- a coil spring 28 biases rear bow 26 in an illustrated clockwise direction to lowered position.
- Top-operating hydraulic cylinders 30, 30' (shown schematically in Figs. 11 - 15) each has a cylinder rod 32 that mounts a clevis 34, best seen in Figs. 8 - 10.
- Clevis 34 includes a slot 36 that receives a drive pin 38 mounted on rear rail
- Clevis 34 mounts a roller 40 which serves as a drive abutment.
- a drive link 42 is pivotally mounted on clevis 34 for movement into (Figs. 1, 2, 7, 8 and 9) and out of (Figs. 3, 4, 5, 6 and 10) a position engaging drive pin 38.
- drive link 42 engages drive pin 38, it traps pin 38 against the outer end of slot 36 such that extension and retraction of cylinder rod 32 will pivot rear rail 22 to raise and lower the convertible top.
- the mechanical arrangement of cylinder 30 is such that rod 32 need be only partially extended (such as to a midpoint) to fully raise the top.
- drive link engages a cam member 44 (Fig. 2) mounted on rear rail 22 which pivots drive link 42 out of driving engagement with drive pin 38 (Fig. 3).
- cam member 44 Upon further extension of rod 32, cam member 44 merely slides along pin 38, which slides along slot 36.
- This further extension of rod 32 engages roller 40 with a cam drive surface 46 on rear bow 26 which raises rear bow 26 (Fig. 4) against the bias of spring 28.
- mechanical linkage 34 - 46 and spring 28 operate rear bow 26 at the ends of hydraulic cylinder operation to automatically raise and lower rear bow 26.
- rear bow 26 rests atop the vehicle top storage compartment cover, or tonneau (not illustrated), which covers the top storage well (not shown), where it is latched. All of this is well-known and forms no part of this invention.
- the raising of rear bow 26 just described allows the tonneau to be opened by rods 50, 50' of cylinders 52, 52' (Figs. 11 - 15).
- the rods 32, 32' of cylinders 30, 30' are partially retracted to the midpoint (Figs. 5, 6), which allows spring 28 to lower rear bow 26.
- drive link 42 disengages cam member 44.
- cylinders 30, 30' and 52, 52' are supplied with hydraulic pressure fluid by a motor-driven bi-directional hydraulic pump 54 through a control valve 56, which is remotely operated either manually
- Valve 56 is spring biased to the Figs. 14, 15 position, and is moved to the Figs.
- Valve 56 has five ports 60, 62, 64, 66, 68.
- Ports 60 and 66 are connectable to one side 70 of pump 54, while ports 62 and 68 are alternately connectable to the other side 72 of pump 54.
- Port 62 is a blind port.
- valve 56 is deactuated and biased to its leftward position.
- Pump 54 is inoperative and the top floats, as fluid can flow between cylinder ends through pump 54, while the tonneau is locked by blockage of the cylinder rod ends. This is the normal position with the vehicle top either raised or lowered and relieves any hydraulic stress on the system.
- Fig. 12 illustrates Condition 2, with pump side 70 pressurized to extend cylinders 30, 30'. If the top were lowered, the cylinders would start from a fully retracted position and this would raise the top and then raise rear bow 26.
- Fig. 13 illustrates Condition 3, with the pump 54 reversed to pressurize pump side 72 to retract cylinders 30, 30' and lower the top. Initial movement of the cylinders will operate to raise rear bow 26.
- Fig. 14 illustrates Condition 4, with valve 56 actuated and pump side 72 pressurized to extend cylinders 52, 52' to open the tonneau.
- Fig. 15 illustrates Condition 5, with valve 56 actuated and pump 54 reversed to pressurize pump side 70 to retract cylinders 52, 52' to close the tonneau.
- Valve 56 is then moved to the Fig. 14 position to enable pump 54 to operate cylinders 50, 50' and open the tonneau (Condition 4).
- valve 56 is moved to the Fig. 12 position to partially extend cylinders 30, 30' and raise the top (Condition 2).
- Valve 56 is then moved to the Fig. 15 position enable reversed pump 54 to retract cylinders 50, 50' and close the tonneau (Condition 5).
- Valve 56 is then moved back to the Fig. 12 position enable reversed pump 54 to fully extend cylinders 30, 30', which operates mechanical linkage 34 - 46 to enable spring 28 to lower rear bow 26 into engagement with the tonneau, where it may be latched by means not illustrated.
- the vehicle may optionally include an interlock (not illustrated) which prevents top operation when the vehicle is moving).
- Valve 56 then returns to the Fig. 11 position (Condition 1).
- valve 56 When it is desired to lower the top, valve 56 is initially moved to the Fig. 12 position to partially retract cylinders 30, 30' and actuate mechanical linkage 34 - 46 to raise rear bow 26 against the bias of spring 28. Valve 56 is then moved to the Fig. 14 position to extend cylinders 50, 50' and open the tonneau (Condition 4), whereafter it is moved to the Fig. 13 position to fully retract cylinders 30, 30' and lower the top (Condition 3). When the top is lowered, valve 56 is moved to the Fig. 15 position to close the tonneau (Condition 5). Valve 56 then returns to the Fig. 11 position (Condition 1).
- the 2-way 5-position valve 56 of this invention provides an efficient hydraulic operation of the cylinders, and combines with the mechanical linkage to provide a simple, inexpensive, yet efficient and effective convertible top control mechanism.
