Accordingly, a stable engagement state can be always ensured over a wide rotation range of the lock lever, and a smooth operation can be performed.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to moving a slideable and tiltable panel such as a sunroof panel backward from a closed position to a tilted-up position. The present invention relates to a slide and tiltable panel forward / backward movement restricting device provided for the purpose of preventing backlash and rattling. 2. Description of the Related Art As a sunroof panel front-rear movement restricting device in an inner slide type sunroof device having a tilt-up mechanism, a front slider is rotatable except when the rear end of the sunroof panel is lowered. Japanese Patent Publication No. 5-23 is configured such that one end of a lock lever pivotally supported by the shaft is engaged with an engaged portion formed on a guide rail.
No. 208 is disclosed. According to this conventional structure, when the rear end of the sunroof panel is lowered (tilted down) from the upper surface of the roof, the other end of the lock lever is pushed down on the lower surface of the sunroof panel, and the lock lever is moved from the engaged portion of the guide rail to the lock lever. Of the sunroof panel is unlocked and the rear end of the sunroof panel is lifted (tilted up) and the other end of the lock lever is separated from the lower surface of the sunroof panel. Are engaged so that the sunroof panel is locked. [0004] However, in this prior art, the engaged portion to which one end of the lock lever engages at times other than tilt-up has a mere hole opened in the guide rail. The engaging portion provided at one end of the lock lever is also a mere projection protruding downward, and particularly in a section in the middle of tilting down from the closed position of the sunroof panel, the downwardly extending engaging projection with respect to the inner edge of the hole. Since the angle tends to be inclined backward, there is a possibility that the engaging portion of the lock lever may be disengaged if a large load is applied to the rear portion of the sunroof panel during tilt-up. The present invention has been devised in order to solve such problems of the prior art, and the main object of the present invention is to increase the holding strength when an external force is applied to the sunroof panel in a tilted state. It is an object of the present invention to provide a slide and tiltable panel longitudinal movement restricting device which can be further enhanced. In order to achieve the above object, according to the present invention, a front slider (12) slidably supported on a guide rail (17) is rotatably supported by a shaft, and An engaging portion (engaging projection 20) is provided at one end of the engaging portion (engaging protrusion 20) extended downward so as to engage with an engaged portion (engaged hole 22) provided on the guide rail from the closed position to the tilt-up position. The other end is pushed down by the panel which is always resiliently biased in a direction in which the engaging portion is engaged with the engaged portion, and is lowered at the time of tilt down, so that the engaging portion engages with the engaged portion. The slide and tiltable panel having the lock lever (18) to be released has a front-rear movement restricting device in which the abutting surfaces of the engaged portion and the engaging portion are centered on the rotation axis of the lock lever. Characterized by being substantially along an arc of radius (R) It was assumed. With this configuration, the angle between the engaging portion of the lock lever and the engaged portion of the guide rail in the locked state with respect to the sliding direction of the panel becomes acute, so that the lock lever extends over a wide range of rotation of the lock lever. Thus, a stable engagement state can always be ensured. In addition, since the contours of the contact surfaces of the engaged portion and the engaging portion coincide with the rotation trajectory of the lock lever, smooth operation becomes possible, and generation of abnormal noise and the like can be suppressed. The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a perspective view of a main part of a vehicle showing an outline of a sunroof device to which the present invention is applied. The fixed roof 1 of the vehicle is formed with an opening 2 having a substantially rectangular shape having a long side in the vehicle width direction. The opening 2 can be opened and closed by a movable panel 3 formed in a shape corresponding to the inner peripheral contour of the opening 2. As shown in FIG. 2, the movable panel 3 is composed of a glass panel 4 and a metal plate-made glass holder 5 fixed below the outer periphery of the glass panel 4 with an adhesive. A pair of side plates 11 are connected to lower surfaces of both sides of the glass holder 5 via stays (not shown). A front slider 12 is connected to each front end of the both side plates 11 with a pin shaft 13. A rear slider 15 is connected to each intermediate portion of both side plates 11 with a pin shaft 16 in a cam groove 14 formed to perform a tilting operation and a sliding operation. The front and rear sliders 12 and 15 are slidably movable back and forth with respect to a guide rail 17 fixed inside the fixed roof 1. The front slider 12 is connected with a lock lever 18 for restricting the movable panel 3 from moving forward and backward at the limit of the forward movement of the movable panel 3. The lock lever 18 is supported by the front slider 12 with a shaft 19 so as to be tiltable in a seesaw manner at an intermediate portion in the front-rear direction. The lock lever 18 has a downward engaging projection 20 projecting from its front end, and an upward pressing projection 21 projecting from its rear end. The guide rail 17 has a lock lever 18.
Is provided with an engaged hole 22 into which the engagement projection 20 can enter. The lock lever 18 is constantly resiliently biased by a torsion coil spring (not shown) wound around the support shaft 19 in a direction in which the engagement projection 20 at the front end thereof enters the engagement hole 22. When the movable panel 3 is closed, as shown in FIG. 2, the engagement projection 20 protrudes into the engaged hole 22, and the locked state that regulates the forward and backward movement of the movable panel 3 is maintained. ing. In this state, the lower edges of the side plates 11 do not apply a pressing force to the pressing protrusion 21 of the lock lever 18. At the time of tilt-up operation, for example,
When the rear slider 15 is pushed forward by a pull cable or the like, as shown in FIG. Separated from 21. Therefore, the lock lever 18 maintains the state in which the engagement protrusion 20 protrudes into the engaged hole 22, so that the movable panel 3
Raises the rear end in a locked state in which the longitudinal movement is restricted. When the rear slider 15 is pulled backward to open the movable panel 3, the movable panel 3 is first tilted down by the engagement between the pin shaft 16 of the rear slider 15 and the cam groove 14 of the side plate 11. . By this tilt-down operation, the pressing protrusion 21 at the rear end of the lock lever 18 is provided.
Is pushed down by the lower edge of the side plate 11 and the engaging projection 20 at the front end thereof comes out of the engaged hole 22, so that the movable panel 3 is in the unlocked state in which the movable panel 3 can be moved back and forth. If the rear slider 15 is pulled and driven as it is, the movable panel 3 is accommodated in the accommodating portion defined between the lower surface of the fixed roof 1 and the upper surface of the inner frame supporting the guide rail 17. FIG. 5 shows a cross-sectional profile of the inner periphery of the engaged hole 22.
As shown in FIG. 7, the lock lever 18 is inclined along an arc having a radius R with the support shaft 19 as a center when viewed from the side. The engagement protrusion 20 of the lock lever 18 is inclined along a tangent of the arc. Due to this angle of inclination,
When the engagement projection 20 bites into the engagement hole 22 at the time of locking, the engagement projection 2 is pressed when a force for moving the movable panel 3 backward is applied to the movable panel 3 in the tilt-up state.
The holding force between 0 and the engaged hole 22 further increases. As described above, according to the present invention, the contact surfaces of the engagement holes of the guide rails and the engagement protrusions of the lock lever are formed in an arc centered on the support shaft of the lock lever. The angle between the engagement protrusion of the lock lever and the engaged hole of the guide rail in the locked state with respect to the sliding direction of the movable panel becomes acute, so that the rotation range of the lock lever is wide. In this case, a great effect can be achieved in further increasing the holding strength when an external force is applied to the sunroof panel in the tilted-up state. In addition, since the contour of the contact surface between the engaged hole and the engaging projection coincides with the rotation trajectory of the lock lever, the lock lever can be operated smoothly, and the occurrence of abnormal noise is suppressed. Is also effective.
