Description

[Detailed Description of the Invention] Technical Field The present invention relates to a toggle lock mechanism for an opening/closing body that covers an opening of a vehicle.

BACKGROUND ART FIG. 1 shows a vehicle equipped with a conventional toggle lock mechanism. As shown in the figure, the vehicle includes a rear quarter window glass 4 that is swingably attached to a center pillar 2 of a vehicle body 1 at a front end via a pair of hinge mechanisms 3. FIG. 2 shows a cross-sectional view of FIG. 1, and as is clear from the figure, the pin 5 of the hinge mechanism 3 extends in the vertical direction indicated by the arrow g in FIG. Therefore, the rear quarter window glass 4 swings in the horizontal direction.

A toggle lock mechanism 7 is coupled to the rear quarter window glass 4 near its rear end. The toggle lock mechanism 7 is for opening and closing the rear quarter window glass 4, and includes a base 10 fixed to the rear pillar 8 of the vehicle body 1 with a plurality of screws 9, and a support shaft 12 at the front end of the base. A lever 13 is provided so as to be swingable through the lever 13. The support shaft 12 extends parallel to the pin 5 of the hinge mechanism 3, so that the lever 13 swings in the horizontal direction. A handle 14 is attached to the free end of the lever 13 at its intermediate portion, and the support shaft 12
It is rotatably connected by a pin 15 parallel to the . The handle 14 is pivoted at one end to the rear quarter window glass 4 via a connecting piece 17 having a pin 16 serving as a pivot axis. Note that the connecting piece 17 is fixed to the rear quarter window glass 4 by a fixed shaft 18. Further, reference numeral 19 indicates a seal.

In the toggle lock mechanism constructed in this manner, the rear quarter window glass 4 is opened and closed by operating the handle 14 as shown by the two-dot chain line and the solid line in FIG. However, as described above, since the pivot axis of the lever 13 and the pivot axis of the handle 14 are parallel to the pivot axis of the rear quarter window glass 4, it is difficult to open or close the rear quarter window glass 4. A large locking force F (shown in the first diagram) accompanying the operation of the lever 13 and handle 14 is applied to the swing support shaft of the rear quarter window glass 4, that is, the pin 5 of the hinge mechanism 3, at right angles to the central axis of the pin. Therefore, it was necessary to make the structure of the hinge mechanism 3 strong.

FIG. 3 shows a vehicle equipped with a toggle lock mechanism that solves this problem. Note that this vehicle has the same structure as the vehicle shown in FIGS. 1 and 2 except for the parts explained below, and in the following explanation, the vehicle shown in FIGS. The same reference numerals are used for the same parts. Also, Fig. 4 relates to Fig. 3 -
It shows a cross section.

As shown in FIG. 3, the toggle lock mechanism 2
1 is provided corresponding to the rear end of a rear quarter window glass 4 which is swingably attached to the vehicle body 1 via a hinge mechanism 3 at the front end. The toggle lock mechanism 21 includes a base 22 fixed to the rear pillar 8 of the vehicle body 1 with, for example, screws 9. As is clear from FIG. 4, a lever 23 is swingably provided at the front end of the base 22 via a support shaft 24. As shown in FIG. As shown in Figure 3,
The central axis of swing of the rear quarter window glass 4, that is, the central axis 2 of the pin 5 (shown in the second figure) of the hinge mechanism 3
5 and the central axis 26 of the support shaft 24 intersect with each other at an angle θα. A handle 27 is rotatably connected to the free end of the lever 23 at an intermediate portion thereof by a pin 28 extending parallel to the support shaft 24 . The handle 27 is pivoted at one end to the rear quarter window 4 by a coupling piece 30 having a pin 29 as a pivot axis extending parallel to the support shaft 24 and the pin 28.

As shown in FIGS. 4 and 5, the handle 2
By rotating 7, the rear quarter window glass 4 is opened and closed.

In this way, in the toggle lock mechanism, the pivot axis of the lever 23 and the pivot axis of the handle 27 intersect with the pivot axis of the rear quarter window glass 4 at an angle of, for example, θα. ing. Therefore, the lever 2 when opening and closing the rear quarter window glass 4
3 and the large locking force F (shown in FIG. 6) accompanying the operation of the handle 27 is the pivot support shaft of the rear quarter window glass 4, that is, the pin 5 of the hinge mechanism 3.
is applied at an angle of 90°-θα with respect to the central axis 25 of the pin. Therefore, the component force of the locking force F in the direction perpendicular to the central axis 25 of the pin 5 is extremely small, and the influence of the locking force F on the hinge mechanism 3 including the pin 5 is not a problem.

By the way, the toggle lock mechanism 21 is designed to be in a stable state in the state shown in FIG. 5, that is, when the rear quarter window glass 4 is opened. However, in reality, the rear quarter window glass 4 swings vertically around the hinge mechanism 3 due to the vertical vibration of the vehicle body while driving, and especially when the rear quarter window glass 4 swings downward, the glass itself There was a problem in that unreasonable force was applied to the hinge mechanism 3 due to its own weight.

Summary of the invention The present invention was made in view of the above points, and its purpose is to prevent excessive force from being applied to the hinge mechanism that swingably supports the opening and closing body when opening and closing the opening and closing body; To provide a toggle lock mechanism for an opening/closing body of a vehicle, which prevents overload from being applied to the hinge mechanism due to vertical movement of the windshield due to vehicle body vibration, and which has a simplified structure and reduced cost. be.

Structure of the invention The toggle lock mechanism for a vehicle opening/closing body according to the present invention is a toggle locking mechanism for an opening/closing body attached to the vehicle body at one end so as to be swingable in a substantially horizontal direction. and includes a lever swingably provided on the vehicle body, a handle rotatably connected to the free end of the lever, and a connecting piece that pivotally connects one end of the handle to the opening/closing body. The pivot axes of the lever and the handle intersect with the pivot axis of the opening/closing body, and when the opening/closing body reaches the open state, it comes into contact with the handle and moves the handle in the direction of the opening operation. It has an abutment structure that restricts rotation, and the abutment structure is characterized by comprising the surface formed on the coupling piece.

Embodiment Hereinafter, a vehicle equipped with a toggle lock mechanism as an embodiment of the present invention will be described with reference to FIGS. 6 to 10. The vehicle is constructed in the same manner as the vehicle shown in FIGS. 1 and 2 and the vehicle shown in FIGS. 3 and 4, except for the parts described below. The same reference numerals are used for parts that are the same as those of the previously described vehicles. Further, FIGS. 7 and 9 show a - cross section and a - cross section, respectively, with respect to FIG. 6.

As shown in FIGS. 6 and 7, a toggle lock mechanism 31 is provided corresponding to the rear end of a rear quarter windshield 4 that is swingably attached to the vehicle body 1 via a hinge mechanism 3 at the front end. It is being The toggle lock mechanism 31 has a base 32 fixed to the rear pillar 8 of the vehicle body 1 with, for example, screws 9.
It is equipped with As is clear from FIG. 9, a lever 33 is swingably provided at the front end of the base 32 via a support shaft 34. As shown in FIG. As shown in FIG. 6, the central axis of swing of the rear quarter window glass 4, that is, the central axis 35 of the pin 5 of the hinge mechanism 3
and the central axis 36 of the support shaft 34 intersect with each other at an angle θα. That is, the large locking force accompanying the operation of the lever 33 and handle 38 that occurs when opening and closing the rear quarter window glass 4 as described below: F is the swing support shaft of the rear quarter window glass 4, that is, the pin of the hinge mechanism 3. 5 at an angle of 90°-θα with respect to the central axis 35 of the pin.

A handle 38 is rotatably coupled to the free end of the lever 33 at an intermediate portion thereof by a pin 39 extending parallel to the support shaft 34 . One end of the handle 38 is pivotally connected to the rear quarter window glass 4 by a connecting piece 41 having a pin 40 serving as a pivot axis. This pin 40 extends parallel to the support shaft 34 and pin 39.

As is particularly clear from FIG.
is formed so that its cross-sectional shape substantially perpendicular to its longitudinal direction is U-shaped. On the other hand, a round hole 43 is formed in the connecting portion 42 of the connecting piece 41 with the pin 40, and the connecting piece 41 is slidably engaged with the pin 40 in the round hole. That is, handle 3
8 and the connecting piece 41 are movable relative to each other in the direction of their pivot axis, that is, the center axis of the pin 40, and automatically compensate for dimensional variations in mounting the rear quarter window glass 4 to the vehicle body 1. It is made so that it can be absorbed.

In the toggle lock mechanism constructed in this manner, the rear quarter window glass 4 is opened and closed by rotating the handle 38 as shown in FIGS. 9 and 10. As is clear from FIGS. 9 and 10, the first
surface 45 and the pivot axis or pin 40 of the handle 38 relative to the rear quarter window 4.
and the central axis of the pin 39.
6 exists, but when the rear quarter window glass 4 is open, these two surfaces 45 and 46 form a larger angle: θb than when the rear quarter window glass is closed, resulting in a wide angle state. .

The coupling piece 41 has a contact near the pin 40 that comes into contact with an abutment surface 48 formed on the handle 38 when the two surfaces 45 and 46 reach the wide angle state to restrict rotation of the handle 38. A regulating contact surface 49 is formed as a contact structure. Therefore, the rear quarter window glass 4 in the open state is forcibly restricted from swinging in the vertical direction about the hinge mechanism 3 due to vibrations of the vehicle body while the vehicle is running.

Note that an abutment member that abuts the abutment surface 48 formed on the handle 38 to restrict rotation of the handle may be provided separately from the coupling piece 41. However, by using the coupling piece 41 as an abutting member for restricting rotation of the handle 38 in this way, the number of parts is reduced.

In addition, although the toggle lock mechanism is provided in the rear quarter window glass in this embodiment, the invention is not limited to this, and the present invention can be applied to any opening/closing body that swings open and close in a substantially horizontal direction. It goes without saying that there is.

Further, as shown in FIG. 6, in this embodiment, the central axis 35 of the pin 5 (shown in FIG. 7) of the hinge mechanism 3 that supports the rear quarter window glass 4 is
and the central axis 36 of the support shaft 34 of the lever member 33, which is a component of the toggle lock mechanism 31, is approximately 70 degrees. Any angle can be taken as shown.

Effects of the Invention As detailed above, in the toggle locking mechanism for a vehicle opening/closing body according to the present invention, the central pivot axis of the lever, the central pivot axis of the handle, and the pivoting center of the opening/closing body are the constituent members of the toggle lock mechanism. The axis is arranged so that it intersects with the axis. Therefore, if the angle of this intersection is, for example, θα, then the locking force (indicated by F in FIG. 6) accompanying the operation of the lever and handle when opening and closing the opening and closing body is applied to the swinging support axis of the opening and closing body. That is, it is applied to the pin of the hinge mechanism at an angle of 90°-θα with respect to the central axis of the pin. That is, when θα is, for example, about 70°, the component force of the locking force F in the direction perpendicular to the central axis of the pin is Fsin(90°−θα)≈Fsin(90°−70 °)≒0.34F, and the locking force on the hinge mechanism including the pin:
The influence of F is such that it is not necessary to take it into account.

In addition, in the toggle lock mechanism of the vehicle opening/closing body according to the present invention, when the opening/closing body is opened, the first surface including the central axis of swing of the lever and the central axis of rotation of the handle, and the handle relative to the opening/closing body. a second axis including a pivot axis and a rotation axis of the handle;
A contact structure is provided that contacts the handle and restricts rotation of the handle in the opening operation direction when the surface reaches the wide-angle state. Therefore, the opening/closing body in the open state is forcibly restricted from swinging in the vertical direction about the hinge mechanism due to vibrations of the vehicle body while driving, and therefore, no overload is applied to the hinge mechanism. There isn't.

Furthermore, in the toggle lock mechanism according to the present invention, the abutment structure is comprised of an abutment surface formed on a connecting piece that pivotally connects one end of the handle to the opening/closing body.

In this way, because the joint piece that pivots to the handle opening/closing body is also used as an abutment member that restricts the rotation of the handle, the number of parts is reduced, and the structure is simplified and costs are reduced. A reduction in the amount of carbon dioxide has been achieved.
