Description

  The present invention relates to a wire type window regulator.

Some wire type window regulators for opening and closing a window glass of an automobile have a wire stretched between an upper wire guide and a lower drum in the panel space of the door panel. In this wiring, the end portion of the wire that has been wound around the wire guide (closed side wire) and the end portion of the wire that extends from the drum (open side wire) are attached to the carrier, and the carrier is guided by the guide rail. There is known a railless type window regulator that can be moved up and down without any problem. The carrier is a member that supports the lower end of the glass.
The closed side wire is a wire part on the side that pulls up the carrier by being pulled by the drum and moves the window glass in the closing direction when viewed from the center of the carrier, and the open side wire is the opposite, It is a wire portion on the side where the carrier is pulled down by being pulled by the drum and the window glass is moved in the opening direction.

The window regulator of Patent Document 1 is a railless type, and a closing side wire (cable) and an opening side wire are attached to a carrier (carrier plate) that is not guided by a guide rail.
In such a window regulator, the ends of the closing side wire and the opening side wire are arranged in a straight line in the vertical direction on the carrier, so that the vertical dimension of the carrier becomes large and affects the glass ascending / descending range.

Japanese Patent No. 4365585

  The problem to be solved by the present invention is that the vertical dimension of the carrier supporting the window glass is reduced to widen the range of raising and lowering of the window glass. An object of the present invention is to provide a wire type window regulator that has a stable posture and can open and close a window glass smoothly.

The present invention employs the following configuration for a carrier that is moved without being guided by a guide rail in a window regulator.
The carrier is a thick plate-like block having an upper surface and a lower surface, a front side surface and a back side surface.
The block includes a fixing hole for fixing the window glass and has a closed-side wire arrangement portion and an open-side wire arrangement portion.

  The closed-side wire placement portion includes a first wire guide wall, a first inclined wire groove, a first wire locking portion, and a first wire restricting portion. The first wire guide wall is formed by a step on the surface of the block and is a wall from the upper surface toward the center of the fixing hole. The first inclined wire groove is a groove that extends downward from the fixed hole side of the first wire guide wall and is connected to the bottom surface side of the step. The first wire locking portion is provided at the end of the first inclined wire groove. The first wire regulating portion is a position where the fixed hole side end of the first wire guide wall and the first inclined wire groove are connected to each other, and is a portion where the closing side wire is in contact.

Open-side wire placement portion is disposed at a position of the closing side wire placement portion and the fixing hole point symmetric centering on the, in the center of the fixing hole from the bottom surface of the formed by the step surface of the block A second wire guide wall heading, a second inclined wire groove connected to the bottom surface side of the step from the fixed hole side of the second wire guide wall to the other side, and a second wire provided at an end of the second inclined wire groove The locking part and a second wire restricting part provided at the fixed hole side end of the second wire guide wall and in contact with the opening side wire.

  When the wire is tensed after routing, the closed-side wire arrangement portion and the open-side wire arrangement portion are arranged such that the first wire guide wall and the second wire guide wall face the wire as wall surfaces, and the window in the length direction. Along the opening and closing direction of the glass, the first inclined wire groove and the second inclined wire groove are point-symmetric with respect to the center of the fixing hole. The closed-side wire is in contact with the first wire restricting portion and the position is restricted from the rear by the first wire guide wall, and the open-side wire is in contact with the second wire restricting portion and is located at the second wire guide wall from the front Is regulated.

Since the first wire locking portion of the closing side wire and the second wire locking portion of the opening side wire are arranged on both sides of the fixing hole, the vertical dimension of the carrier can be reduced.
On the other hand, when the wire is tensioned, the closing side wire and the opening side wire are in a straight line passing through the center of the fixing hole, so that the movement of the carrier is stable and the window glass can be opened and closed smoothly.

  Since the carrier includes first and second wire guide walls and first and second inclined wire grooves, the carrier rotates toward the wire and the first or second wire guide wall collides with the tensioned wire. In such a case, the rotation is suppressed by the tension of the wire. Further, when the carrier rotates in the direction away from the wire, the rotation of the carrier is returned by the moment due to the wire tension between the first and second wire restricting portions. For this reason, the stable movement of the window glass can be maintained.

  After the wire is loosened, the wire end is engaged with the carrier, and then the wire end is firmly locked to the carrier by tensioning the wire. For this reason, a wire can be easily and reliably attached to a carrier.
