Description

slide lock

technical field

The present invention relates to a slide lock device provided between a fixed side member and a movable side member for locking the rotation of the movable side member. the

Background technique

In order to keep the door open, the car needs to prevent the door from being automatically closed due to the inclination of the slope or its own weight, and the door from being closed due to wind pressure. In addition, the center console (center console) installed in the cabin makes it easy to take out the contents inside by keeping the sliding door open. The slide lock device is used to lock the rotation of such a vehicle door or a movable side member such as a slide door. the

Patent Document 1 describes a conventional slide lock device for maintaining an opened state of an automobile door. This device has a lever rotatably supported on the vehicle body side and a holding member held on the vehicle door side. A plurality of raised portions are formed on the upper and lower surfaces of the lever along the length direction. The raised portion of the lever penetrates through the holding member. The holding member has a sliding element that displaces while sliding the protruding portion of the lever that passes through, and an elastic body that presses the sliding element against the protruding portion by biasing. the

In this structure, when the door is opened, the holding member moves along the lengthwise direction of the lever as the door is opened. When the holding part is moved, the elastic body is compressed due to the sliding element moving onto the bead of the lever. Due to this compression reaction, a high sliding resistance occurs between the sliding element and the lever. Therefore, the open state of the vehicle door can be maintained. the

(first embodiment)

1 is a plan view showing a slide lock device according to a first embodiment of the present invention, FIG. 2 is a longitudinal sectional view of the slide lock device, and FIG. 3 is a right side view. Fig. 4 shows the sliding part, Fig. 5 shows the leaf spring, Fig. 6 shows the release part, and Figs. 7 to 10 show the action. the

As shown in FIG. 1 , the sliding locking device includes a lever plate 1 , a sliding part 3 , a locking block 4 and a releasing part 5 . The sliding locking device of this embodiment is used to keep the opened state of the vehicle door. The vehicle body is a fixed side component, and the door is a movable side component mounted on the vehicle body in a forward and reverse direction. Hereinafter, the fixed-side member will be described as a vehicle body, and the movable-side member will be described as a door. the

As shown in FIGS. 1 and 2 , the lever plate 1 is formed in a horizontally long shape, one end side (left end side) is attached to the vehicle body, and the other end side (right end side) is a free end. In order to mount the lever plate 1 on a vehicle body, a circular connecting hole 1 a for connecting to a vehicle body is formed on one end side of the lever plate 1 . By attaching the mounting hole 1a to a mounting shaft (not shown) on the vehicle body side, the entire lever plate 1 can be rotatably supported on the vehicle body side. the

On the lever plate 1, a long hole 1b for guiding the movement of the slide member 3 and the lock block 4 is formed at an approximately middle portion in the width direction. The elongated hole 1b is formed in a horizontally long shape extending in the longitudinal direction of the lever rod 1, and both ends thereof are formed in a closed state. The sliding member 3 and the locking block 4 reciprocate within the length region of the long hole 1b. The long hole 1b is formed to have the same hole width over the entire length, and can guide the movement of the sliding member 3 and the lock block 4 without shaking. In the lever plate 1, both side pieces outside the elongated hole 1b constitute a friction portion 1d. The plate spring 2 of the lock block 4 is in elastic contact with the friction portion 1d. the

As shown in FIG. 4 , the slide member 3 includes a connection surface 3e extending in the vertical direction, and a box-shaped support portion 3c extending from one side of the connection surface 3e. A circular mounting hole 3a for connecting to a door as a movable side member is formed in the upper and lower portions of the connecting surface portion 3e. A lever plate hole 3b through which the lever plate 1 penetrates is formed in a substantially middle portion in the height direction of the connection surface portion 3e and a portion opposite to the support portion 3c. the

The hole 3 b for the lever plate is a rectangular hole slightly larger than the thickness and width of the lever plate 1 . Since the lever plate 1 passes through the lever plate hole 3b connecting the face portion 3e and the lever plate hole 3b of the support portion 3c, the slide member 3 is in a state where the rotation is not restricted, and the slide member 3 can move to the lever plate 1 in this state. Move in the length direction. the

The support portion 3c of the slide member 3 is formed in a box shape extending laterally from one side of the connecting surface 3e, and a storage chamber 3f for accommodating the locking block 4 is formed inside the box shape. The accommodation chamber 3f accommodates the lock block 4, and the release member 5 is attached to the outer surface. And the attached release member 5 is inserted into 3 f of accommodation chambers (refer FIG. 2). the

The locking block 4 includes a leaf spring 2 and a shaft body 6 . The plate spring 2 is a member that contacts the lever plate 1 to generate frictional force. As shown in FIG. 5 , the leaf spring 2 is formed by bending a rectangular plate material into a U-shape, the convex surface of which is in contact with the lever plate 1 . A non-circular shaft hole 2a is formed on the leaf spring 2. Although the axial hole 2a is a non-circular shape obtained by cutting a circle in parallel, it may be polygonal, elliptical, or other shapes. The shaft body 6 passes through the shaft hole 2a. Both side pieces of the leaf spring 2 sandwiching the shaft hole 2a constitute a friction portion 2d that elastically contacts the lever plate 1 to generate a friction force between it and the friction portion 1d. the

As shown in FIG. 2, the shaft body 6 has a shape in which a shaft portion 6b stands up from a large-diameter head portion 6a. The shaft portion 6b passes through the shaft hole 2a of the leaf spring 2, and forms a non-circular outer shape corresponding to the shaft hole 2a. And the non-circular shaft part 6b penetrates the long hole 1b of the lever plate 1 (refer FIG. 1). In this way, since the non-circular shaft portion 6b passes through the long hole 1b of the lever plate 1 , the shaft body 6 cannot rotate relative to the lever plate 1 . Therefore, in the assembled state where the shaft portion 6b of the shaft body 6 passes through the shaft hole 2a of the leaf spring 2 , the leaf spring 2 cannot rotate relative to the lever plate 1 . By restricting the rotation of the leaf spring 2, the contact portion between the friction portion 2d of the leaf spring 2 and the friction portion 1d of the lever plate 1 does not vary. Therefore, a stable frictional force can be generated. the

The shaft body 6 passes through the long hole 1 b of the lever plate 1 , so that the locking block 4 can move in the length direction of the lever plate 1 . A pair of leaf springs 2 are provided to clamp the lever plate 1 from both sides. Furthermore, a pair of pressure plates 7 are provided to face the pair of leaf springs 2 . The pressing plate 7 is located on the outer side (upper and lower sides) of each leaf spring 2 and functions to press the leaf spring 2 from the outside. In this way, the leaf spring 2 can be bent, and at the same time, the bent leaf spring 2 can be reliably brought into contact with the lever plate 1 . the

The aforementioned lock block 4 is housed in the housing chamber 3 f of the slide member 3 . The accommodating chamber 3f of the slide member 3 is formed with a dimension larger than that of the lock block 4, so that the lock block 4 and the slide member 3 can move mutually by an amount corresponding to the dimension. This movement is performed on the lever plate 1 , and the release member 5 described later operates through the relative movement of the lock block 4 and the slide member 3 . the

The release part 5 is a part to enter between the leaf spring 2 and the lever plate 1, and as shown in FIG. 6, forms a wedge piece 5a for entering between the leaf spring 2 and the lever plate 1. The wedge piece 5a extends laterally from one side of the substrate 5b, and the thickness gradually becomes thinner toward the front end side, and the width gradually becomes narrower. In this way, access between the leaf spring 2 and the lever plate 1 is easy. the

As shown in FIG. 6 , the front end portion of the wedge piece 5 a of the release member 5 is divided into two forks, and each forked portion 5 d enters between the friction portion 2 d of the leaf spring 2 and the friction portion 1 d of the lever plate 1 . An empty sipe recess (a recessed portion) 5c is formed between the bifurcated portion 5d. The shaft portion 6b of the shaft body 6 enters the rear recessed portion 5c. Thus, the bifurcated portion 5d can easily enter between the leaf spring 2 and the lever plate 1 . As shown in FIGS. 2 and 3 , the release member 5 is mounted on the outer surface of the housing chamber 3 f and fixed to the slide member 3 by screwing in a screw 8 . When this attachment is performed, since the wedge piece 5a enters into the long hole 1b of the lever plate 1, the wedge piece 5a moves in the long hole 1b of the lever plate 1. As shown in FIG. the

As shown in FIGS. 1 and 2 , in the sliding locking device of this embodiment, the lever plate 1 penetrates the sliding member 3, the shaft body 6 is inserted into the housing chamber 3f of the sliding member 3, and the shaft portion 6b of the shaft body 6 penetrates the lever plate 1. The plate spring and the pressure plate 7 on the lower side are inserted into the long hole 1b of the lever plate 1 with the shaft portion 6b. Then, the shaft portion 6b is assembled by passing through the plate spring 2 and the pressure plate 7 on the upper side of the lever plate 1, and caulking the pierced ends. The plate spring 2 is bent by riveting the through end, and the plate spring 2 is pressed against the lever plate 1 by the pressing plate 7 . In this way, the friction portion 2d of the leaf spring 2 having a convex surface is in a state of pressing the friction portion 1d of the lever plate 1 . the

When performing the above assembly, it is possible to carry out lubrication treatment such as filling a lubricant such as grease between the leaf spring 2 and the lever plate 1, or to apply fluorine-based resin to either or both of the leaf spring 2 and the lever plate 1. handling, thereby ensuring smooth motion. In addition, instead of caulking the shaft portion 6b of the shaft body 6, a threaded portion is formed at the tip of the shaft portion 6b, and a fastening member such as a nut is screwed to the threaded portion and fastened. After the above assembly is completed, the mounting hole 1a of the lever plate 1 is connected to the vehicle body, and the mounting hole 3a of the sliding part 3 is connected to the vehicle door. This is how the slide lock is installed on the car. the

The operation will be described below. In this embodiment, the spring force of the leaf spring 2 pressing the lever plate 1 is set to be greater than the force of closing the door. And, the spring force of the plate spring 2 pressing the lever plate 1 is set to be greater than the frictional force of the wedge piece 5a of the releasing part 5 entering between the plate spring 2 and the lever plate 1. In this way, the wedge piece 5 a is pushed out between the leaf spring 2 and the lever plate 1 , and the release member 5 is disengaged from the space between the leaf spring 2 and the lever plate 1 . the

1 to 3 show operations when opening a door as a movable side member. At this time, the release member 5 does not enter between the leaf spring 2 and the lever plate 1 . In this state, by opening and rotating the door, a moving force indicated by an arrow M in FIG. 2 along the lever plate 1 acts on the slide member 3 . As the slide member 3 moves, the inner surface of the connection surface 3 e abuts on the lock block 4 , and the lock block 4 moves along the lever plate 1 together with the slide member 3 . At this time, since the plate spring 2 is in contact with the lever plate 1, predetermined sliding friction (frictional force) is generated. The sliding friction at this time is shown in Fig. 11(a). This friction creates a fixed and highly loaded friction. Thus, once the rotation of the door has stopped, the door can remain open in this position. the

7 and 8 show the state of moving to the operation of closing the door after opening the door. That is, when the door is rotated in the opposite direction. At this time, the locking block 4 is stopped on the lever plate 1 due to the frictional force of the leaf spring 2, but if the door is to be closed, the sliding part 3 installed on the door will move on the lever plate 1 along the arrow N direction of Fig. 8 , The wedge piece 5a of the release member 5 is close to between the leaf spring 2 and the lever plate 1. the

Fig. 9 and Fig. 10 show the closing action of the car door following Fig. 7 and Fig. 8, and the sliding part 3 further moves on the lever plate 1 in the direction of the arrow N (the direction of the locking block 4). During this movement, the wedge piece 5 a of the release member 5 provided on the slide member 3 enters between the leaf spring 2 and the lever plate 1 . The sliding friction acting on the lever plate 1 via the leaf spring 2 is thus reduced. Fig. 11(b) is a graph at this time, and peak N1 is a high load having the same value as Fig. 11(a). In FIG. 11( b ), after this high load is shown, it becomes a low load. Therefore, when the door is initially closed, the door can be prevented from being closed due to wind pressure or the like by the high load of the peak value N1. Then, since the frictional force of the leaf spring is reduced, the action of closing the door can be performed with a lighter force. the

If the closing of the door is stopped in the middle of the door closing operation, the torque of the door is not transmitted to the slide member 3 . Thus, the locking block 4 is pushed out from the wedge 5 a by the wedge effect between the wedge 5 a of the release member 5 and the spring force of the leaf spring 2 . In this way, since the high load of the plate spring 2 acts on the lever plate 1 again, it is possible to prevent the door from being closed due to the gloomy wind pressure, etc., and to ensure safe operation. the

In the above embodiments, when the plate spring is in contact with the lever plate 1 so that its frictional force acts, the open state of the door can be maintained. And, when the vehicle door is closed, the release member 5 enters between the leaf spring and the lever plate 1 , thereby reducing the frictional force of the leaf spring 2 . Therefore, the frictional force of the plate spring 2 against the lever plate 1 can be adjusted, and operability is improved. the

(second embodiment)

FIG. 12 shows the operation of the second embodiment of the present invention. In this embodiment, the plate thickness of the lever plate 1 is changed in the longitudinal direction, and the friction portion 1d of the lever plate 1 corresponding to the first opening of the door is made thinner than other portions. The region L in FIG. 12( a ) is the sliding friction (frictional force) generated between the plate spring 2 and the lever plate 1 in this part, and a low load is formed. Therefore, the door can be opened with a small operating force when the door is first opened, and there is an advantage of improved operability. the

(third embodiment)

As in the first embodiment, bifurcated wedge pieces 5a, 5a are formed at the front end portions of the respective release members 5, 5. As shown in FIG. The wedge pieces 5a, 5a are more gradually thinned toward the front end side thickness and narrower gradually in width, and are easy to enter between the leaf spring 2 and the lever plate 1. the

In the structure in which the release members 5, 5 are arranged on both sides of the lock block 4, when the slide member 3 moves by the action of opening the door and the action of closing the door, due to the two release members on both sides of the lock block 4 Any one enters between the leaf spring 2 and the lever plate 1, therefore, the frictional force of the leaf spring 2 decreases. Therefore, the door can be operated with very little force. the

In this embodiment, the nut 12 is screwed to the through-end part of the shaft part 6b of the shaft body 6 penetrating through the lock block 4 of the upper and lower leaf springs 2 and 2 . In order to be screwed with the nut 12 , an external thread portion (not shown) is formed on the outer surface of the shaft portion 6 b of the shaft body 6 . The nut 12 is screwed to the shaft portion 6 b so as to come into contact with the upper surface of the pressure plate 7 . In such a structure, by adjusting the tightening amount of the nut 12, the pressing force of the leaf springs 2, 2 acting on the lever plate 1 through the upper and lower pressing plates 7, 7 can be adjusted, and the connection between the leaf springs 2, 2 and the lever plate 1 can be adjusted. the friction force between them. Therefore, adjustments can be easily made according to the weight (load) of movable side members such as doors. the

The elastic member 15 of this embodiment is used to press the pressure plate 7 (lock block 4 ) against the inner surface of the connecting surface portion 3 e of the slide member 3 . the

In this way, in the structure in which the elastic member 15 for urging the locking block 4 (press plate 7) in the sliding direction of the slide member 3 is provided between the storage chamber 3f and the press plate 7, since there is no gap between the press plate 7 and the slide member 3, Therefore, the movement of the sliding member 3 can be immediately transmitted to the lock block 4, and the responsiveness of the movement can be improved. And, when releasing member 5 to enter between leaf spring 2 and lever plate 1 when closing the door operation, if release the operating force to car door, then releasing member 5 leaves leaf spring 2 at once due to the active force of elastic member 15, therefore, plate The high load of the spring 2 acts on the lever plate 1 . Therefore, even if there is no operating force applied to the door, the door can be prevented from being closed due to wind pressure or the like. Furthermore, by applying an initial load to the elastic member 15 to disengage the release member 5 from between the plate spring 2 and the lever plate 1, it is possible to reduce play when opening the door. the

In this embodiment, a bolt is used as the shaft body 6 of the lock block 4 . Then, the nut 12 is screwed to the shaft portion 6 b of the bolt 6 . In such a structure, by adjusting the tightening amount of the bolt 6 with the nut 12, the frictional force generated between the leaf springs 2, 2 and the lever plate 1 can be adjusted similarly to the third embodiment. the
