A device for raising and lowering a door window (for example, a glass window) as (see), a so-called window regulator. The object moving device 1 can be applied not only to the window regulator but also to other devices as long as it is a device for moving the moving object W connected to the moving member 12. The object moving device 1 can be applied to, for example, a device that raises and lowers a seating portion that moves up and down. Further, when walking, the object moving device 1 moves the handle with wheels at the lower end up and down so as to be separated from the wheels by a predetermined length, so that the user holding the handle can walk from the seated state. It can also be applied to a walking support device that supports walking.

The object moving device 1 shown in FIG. 1 is in a state of being viewed from the front, and moves a window glass which is a moving object W connected to a carrier member as a moving member 12.
The object moving device 1 can move the window glass which is the moving object W, and by this movement, the window shielded state and the open state of the window to which the window glass is attached are switched.
The object moving device 1 is attached to the door panel of the vehicle by using the bracket of the guide rail 11 and the fixing portion of the housing.
In the present embodiment, unless otherwise specified, the longitudinal direction of the guide rail 11 of the window regulator is the vertical direction, parallel to the window glass which is the moving object W supported by the window regulator, and perpendicular to the vertical direction. This direction will be described as the left-right direction.

The object moving device 1 is provided with a moving member 12, a driving unit 14, a drum member 15, a cable 16, and a direction changing unit 104, which is a direction changing member, to which a window glass as a moving object W is connected.

<Movement object W>
The moving object W is an object that is connected to the moving member 12 and is moved by the movement of the moving member 12. The moving object W switches between a shielded state and an open state, and moves an object arranged on the moving object. The moving object W comes into contact with the movement inhibitor and is hindered from moving.
In the present embodiment, the window glass which is the moving object W slides with the door sash, and the movement is hindered by the door sash. The door sash corresponds to a movement obstruction.
The moving object W is arranged at a predetermined position when the moving member 12 comes into contact with the regulating member 20 and reaches the first position described later.
In the present embodiment, the moving object W moves following the movement of the moving member 12 which is moved by the winding and unwinding of the cable 16. The moving object W is a window glass, but for example, a window made of metal, resin, or the like may be used in addition to glass. Further, the moving object W may be provided so as to be able to move up and down as a member constituting the seating surface of the seating portion connected to the moving member 12 or as a handle of the walking support device.

<Moving member 12>
The moving member 12 shown in FIGS. 1 and 2 is connected to the moving object W and moves between the first position and the second position.
Here, the first position is an arbitrary position set on one side of the moving member 12 in the moving direction. The first position is a position on one side of the movement limit of the moving member 12, and is defined as an upper limit end of movement on one side of the moving member 12. In the present embodiment, the first position can be said to be the upper end position of the moving member 12 in which the movement of the moving member 12 on one side is restricted. In the present embodiment, this position is a position in which the window is completely shielded by the window glass which is the moving object W and the deadline is closed. The first position is reached by elastic deformation of the elastic member 121 after contacting the regulating member 20.
When the drive unit 14 is at the lower end, the first position is a position far from the drive unit 14. Further, when the guide rail 11 is used as in the present embodiment, the first position is the position on one side of the guide rail 11 and the position on the upper end side of the guide rail 11 extending in the vertical direction.

On the other hand, the second position is an arbitrary position set on the other side of the moving member 12 in the moving direction. The second position is the position on the other side of the movement limit of the moving member 12, and is defined as the lower limit position of the movement on the other side of the moving member 12. In this embodiment, this position is a position in which the window is fully opened by the movement of the window glass, which is the moving object W. In the present embodiment, the second position is a position closer to the drive unit 14 when the drive unit 14 is arranged at the lower end. Further, the second position is located on the other side of the guide rail 11 when the guide rail 11 is used as in the present embodiment, and is the position on the lower end side of the guide rail 11 extending in the vertical direction.

The moving member 12 moves the connected moving object W by moving between the first position and the second position, and in the present embodiment, moves the window glass which is the moving object W. The moving member 12 moves by driving the drive unit 14, and stops moving when the drive unit 14 stops.
The moving member 12 is moved by a cable 16 unwound from the drum member 15 by driving the driving unit 14.
The moving member 12 has an end accommodating portion (not shown) for accommodating the terminal member of the cable 16. In the present embodiment, the moving member 12 includes an end accommodating portion for accommodating the terminal member of the ascending cable 161 for raising the moving member 12, and the terminal member of the lowering cable 162 for lowering the moving member 12. It is provided with an end accommodating portion for accommodating. The ascending cable 161 and the descending cable 162 are led out from each cable accommodating portion of the moving member 12 so that the lead-out portion serves as a fulcrum for ascending or lowering the moving member 12.
In the present embodiment, the moving member 12 is a carrier member that is slidably fitted to the guide rail 11 in the vertical direction while the movement in the left-right direction is restricted by the guide rail 11.
The shape of the carrier member, which is the moving member 12, can be redesigned at any time according to the shapes of the guide rail 11 and the moving object W. In the present embodiment, the carrier member, which is the moving member 12, is a carrier plate formed in a plate shape. In the present embodiment, a window glass as a moving object W is connected to the carrier member which is the moving member 12, fits into the guide rail 11, and moves along the guide rail 11.

The moving member 12 has an elastic member 121 on the first position side.
The elastic member 121 is a member that elastically deforms, is provided on the moving member 12, and comes into contact with the regulating member 20. The moving member 12 reaches the first position when the elastic member 121 comes into contact with the regulating member 20. The elastic member 121 is crushed in contact with the regulating member 20. Even after the elastic member 121 comes into contact with the regulation member 20, the elastic member 121 is deformed by being wound up by the drive source.
Since the elastic member 121 has an elastic force for returning from the elastically deformed state, it has the elasticity to push back the moving member 12 in the state where the moving object is attached from the elastically deformed state. The elastic member 121 can move the moving member 12 to the first position by a predetermined elastic deformation. The elastic member 121 is, for example, rubber or a spring. In the present embodiment, even if the door or the like is curved or the position of the window glass is moved when the upper end of the window glass is restrained when ascending, the moving object W is affected by the restoring force of the elastic member 121. A windowpane can be returned to its original position, the first position.
The elastic member 121 suppresses the movement of the moving object W from the stopped position when the driving unit 14 is stopped after the movement of the moving object W is restrained by the movement obstructor. The elastic member 121 can move the moving member 12 to a predetermined position without applying an excessive load to the moving object W. In the present embodiment, since the moving object W is the window glass, the window can be closed by the window glass without applying an excessive load to the window glass.
When the elastic member 121 has the guide rail 11 like the object moving device 1, the elastic member 121 is provided on the moving member 12 so as to slide opposite to the guide rail 11.

In the object moving device 1 of the present embodiment, the moving member 12 having the elastic member 121 and the guide rail 11 for guiding the movement of the moving member 12 will be described.

In the drum member 15 of the present embodiment, the ascending cable 161 and the descending cable 162 are wound in opposite directions to each other. Depending on the direction of rotation, the drum member 15 winds the ascending cable 161 and pulls the ascending cable 161 or winds the lowering cable 162 and pulls the lowering cable 162.

<Drive unit 14>
The drive unit 14 is connected to the drum member 15 and drives a power source to supply a driving force for rotating the drum member 15 to the drum member 15. The drive unit 14 connects the drum member 15 and the drive source so that the drum member 15 is rotated by the drive of the drive source. The drive unit 14 rotates the drum member 15 by the driving force of the drive source, and winds up the cable 16 and unwinds the cable 16.
The drive unit 14 includes, for example, a motor driven by turning the power on and off, and rotates the connected drum member 15. The drive unit 14 is housed in a motor housing and is fixed to a mounting target such as a substrate or a vehicle body via the motor housing. In the present embodiment, the drive unit 14 is arranged at the lower end of the door panel in the door panel.
The drive unit 14 of the present embodiment is a motor that is electrically driven by a current supplied from a battery. It is desirable that the motor of the drive unit 14 has a so-called clutch function that can lock the output shaft at a predetermined rotation angle.
The drive unit 14 fits the motor shaft into the central portion of the drum member 15, and rotates the drum member 15 by the rotation of the motor shaft. The motor and the drum member 15 transmit the rotational motion of the motor to the drum member 15 via a power transmission unit such as a worm gear. The motor, which is the drive unit 14, is rotationally driven in the forward direction and the reverse direction, whereby the drum member 15 rotates in the forward direction and the reverse direction.
In the present embodiment, the drive unit 14 and the drum member 15 are arranged on the second position side, but the present invention is not limited to this, and the drive unit 14 and the drum member 15 are moved members 12 via the cable 16.

For example, the drum member 15 rotated by the drive unit 14 is provided at a height position between the first position and the second position, and the moving member 12 is provided via a cable 16 that is wound up and unwound from the drum member 15 at this position. May be configured to rise and fall. In this case, the cable 16 wound up and unwound by the drum member 15 is arranged in a cross-shaped manner. This configuration has first and second paths extending in the vertical direction between the first position and the second position, which sandwich the drum member 15 and are vertically separated from each other, and are parallel to each other. The cable 16 wound up and unwound by the drum member 15 passes from the upper end of the first path to the lower end of the second path, passes through the second path, passes from the upper end of the second path to the lower end of the first path, and passes through the first path. It is routed so as to reach the upper end of one route. Then, the moving member 12 is horizontally attached to the cable portion on the first path and the second path, and the cable portion between the upper end of the first path and the lower end of the second path, or the upper end of the second path and the first path. This can be realized by configuring the cable portion between the cable portion and the lower end of the path so as to move in the extending direction of the cable 16 by the drum member 15.

The control unit 18 stops driving the drive unit 14 due to an overcurrent of the drive unit 14 when the moving member 12 reaches the first position. The overcurrent of the drive unit 14 when the moving member 12 reaches the first position is the amount of current supplied to move the moving member 12 generated when the moving member 12 is restrained by the movement obstructor. This is the current that exceeds the current supplied to the drive unit 14. The movement obstructor that restrains the moving member 12 may be a regulating member 20 that restricts the ascent of the moving member 12 via the elastically deformed elastic member 121, or the upper end of the window glass that is the moving object W. It may be a door sash that hits.
The control unit 18 has a sensor that detects an overcurrent to the motor in the drive unit 14 that is the drive control target, and the regulation member 20 and the moving member 12 are in contact with each other by this sensor, and the elastic member 121 of the moving member 12 is in contact with the motor.

Details of the upper joint member 10 will be described later.

<Regulatory member 20>
The regulating member 20 regulates the movement of the moving member 12. The regulating member 20 abuts on the moving member 12, specifically, the elastic member 121 provided on the moving member 12, hits the moved moving member 12, and functions to receive a force from the moving member 12, and the moving member 20 functions. Twelve moving positions are specified. The movement of the moving member 12 to the first position side is a movement of the moving member 12 to the upper side by the operation of closing the window. In the upward movement of the moving member 12 that moves by winding the cable 16, the regulating member 20 comes into contact with the moving member 12 when it reaches the first position and undergoes a predetermined elastic deformation. The window glass, which is the moving object W, is fixed at the regulated position, which is the position where the window glass comes into contact with the upper side of the sash and reaches the first position. The regulating member 20 is fixed to the mounting target so as not to move due to contact with the moving member 12.
In the state where the regulating member 20 is in contact with the moving member 12 and in contact with the elastic member 121 of the moving member 12, the moving member 12 is not positioned at the first position, and after the elastic member 121 in contact with the regulating member 20 is elastically deformed. Positions the moving member 12 at the first position. In the present embodiment, this first position is a position in which the window is closed by the window glass which is the moving object W to move. The deadline position is the state where the window glass is in contact with the door sash in the moving direction, that is, the state where the window glass is in contact with the bottom surface of the door sash having a concave cross section and the state where the window glass is not in contact with the bottom surface of the door sash. It also includes the position where the concave door sash is inserted into the opposite portion across the bottom surface to substantially close the window.

The regulating member 20 regulates the movement of the moving object W by restricting the movement of the moving member 12. The regulating member 20 is fixed at the regulating position so that it can come into contact with the elastic member 121.
The restricting member 20 is fixed at a restricting position where the elastic member 121 comes into contact with the moving member 12 and undergoes a predetermined elastic deformation and then reaches the first position when the moving member 12 is moved to the first position side. The regulated position is a position where the moving member 12 is located at the first position. The moving member 12 may be located at the first position when the window glass provided as the moving object W is closed on the door.
The restricted position may be a position that abuts on the moving member 12 and restricts the movement of the moving member 12. By providing the regulating member 20 at the regulating position, the moving member 12 reaches the first position with the elastic member 121 crushed. The moving member 12 in which the elastic member 121 reaches the first position by elastic deformation while being crushed is in a state of having the elastic member 121 in the crushed state. The moving member 12 that has reached the first position due to the restoring force of the elastic deformation is moved to a position where the moving member 12 exceeds the first position on the upper end side, and then is on the opposite side of the ascending direction due to the returning force of the elastic member 121. In other words, it is returned to the lower end side and reaches the first position in the lowered state.

<Operation of object moving device>
Subsequently, the operation method of the window regulator, which is the object moving device 1 of the embodiment, will be described. In the window regulator, the glass holder 122 attached to the window glass as the moving object W is fastened to the moving member 12 by using a fastening member 101 such as a bolt. The fixed window glass can move between the fully open position and the deadline position by raising and lowering the moving member 12.
Here, in the operation of the window regulator, in particular, the window closing operation by the window glass which is the moving object W connected to the moving member 12 by moving the moving member 12 will be described.

13 to 15 show the operation of the window glass via the moving member 12 of the window regulator, and FIG. 13A is a schematic view showing the window glass when the moving member 12 is positioned at the lower limit position. , FIG. 13B is a schematic view showing a rising window glass. 14 (a) is a schematic view showing immediately before the window glass rises to the maximum, FIG. 14 (b) is an enlarged view of the upper edge portion of the window glass, and FIG. 14 (c) shows the regulating member 20 and the elastic member 121. 14 (d) is a schematic view showing the window glass when it is raised to the maximum, FIG. 14 (e) is an enlarged view of the upper edge portion of the window glass, and FIG. 14 (f) is the regulating member 20. It is an enlarged view of the part of the elastic member 121. 15 (a) is a schematic view showing the window glass after the window glass is raised to the maximum and the drive unit 14 is stopped, and FIG. 15 (b) is an enlarged view of the upper edge portion of the window glass, FIG. 15 (c). ) Is an enlarged view of a portion between the regulating member 20 and the elastic member 121.

In the state of FIG. 13A, the driving unit 14 is driven by the control of the control unit 18 to raise the moving member 12. Then, as shown in FIG. 13B, the moving member 12 rises along the guide rail 11, and the window glass, which is the moving object W, also rises accordingly. The window glass slides in the door sash F and rises.
Then, in the process of further ascending, the elastic member 121 of the moving member 12 comes into contact with the regulating member 20 (see FIG. 14A). At this time, the elastic member 121 of the moving member 12 is in contact with the regulating portion 21 of the regulating member 20, and the elastic member 121 is not yet elastically deformed. Therefore, in this state, the moving member 12 is lower than the movable uppermost position, and the upper edge of the window glass (moving object W) is the door sash F (also referred to as a door roof) as a movement obstructor or the inside of the roof. Not hitting the fastener.

Further, when the moving member 12 is raised by the driving of the driving unit 14, the elastic member 121 of the moving member 12 presses the regulating member 20 upward as shown in FIG. 14D. At this time, since the regulating member 20 is fixed at the regulated position, the regulating member 20 does not move even when pressed by the elastic member 121, and the elastic member 121 is elastically deformed (see FIG. 14 (f)).
While the elastic member 121 is elastically deformed and crushed, the moving member 12 further rises, the window glass which is the moving object W hits the door sash F, and the rising is restricted at the upper end restraint position (FIG. 14 (e)). reference). Alternatively, the moving member 12 is restricted from moving upward by the regulating member 20 via the elastic member 121 that is crushed by the elastic deformation.
As a result, the ascending of the moving member 12 is braked, and an overcurrent flows through the motor of the drive unit 14. The control unit 18 detects this and stops the drive unit 14. Specifically, the energization of the drive unit 14 is stopped. At this time, the window glass tends to move downward from the upper end restraint position due to the reaction force received from the door sash F. If the reaction force is strong, the window glass will move from the upper end restraint position where it stopped. When the window glass moves downward, the moving member 12 connected to the window glass also moves down, and the window glass may not be in the closed state.

The deflection of the ascending cable 161 and the descending cable 162 can be regulated by the clutch function of the motor connected via the ascending cable 161 and the descending cable 162, although the movement of the window glass can be regulated at a desired position. It may not be possible to regulate.
On the other hand, in the present embodiment, the window glass is closed because the downward movement of the window glass, which is the moving object W, is caused by the returning force of the elastic member 121 after the elastic deformation that abuts on the regulating member 20. It is possible to maintain the state of being positioned at the original position which is the state (see FIGS. 15 (b) and 15 (c)).

As described above, according to the present embodiment, the upper end of the window glass is stopped when the drive unit 14 is stopped after the window glass, which is the moving object W, is restrained from moving by the door sash F, which is a movement obstructor. The load on the door sash F at the restrained position can be alleviated.
Therefore, when the window glass receives the reaction force from the door sash F, the door itself having the window glass does not bulge outward with the upper end of the window glass as a fulcrum.

In addition, the details specifically shown in the embodiment can be appropriately changed without departing from the spirit of the invention.

The present invention can be used for a window regulator that raises and lowers the glass window of a vehicle such as an automobile.
