Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door device for a vehicle applied to a cold storage container vehicle such as a freezing vehicle or a cold storage vehicle.

[0002]

2. Description of the Related Art Conventionally, as a sliding door device for a vehicle applied to an insulated container vehicle, for example, Japanese Utility Model Laid-Open No. 3-934.
No. 95 is known. In this conventional vehicle slide door device, an opening is provided on a side surface of a container, and linear rails are provided above and below the opening so as to extend to the rear of the opening. The rotating pipes are supported so as to be able to slide back and forth and horizontally in a horizontal direction, and a slide door is supported by these rotating pipes.

According to this conventional device, the slide door can be displaced in the vehicle exterior and vehicle interior directions by rotating the rotation pipe with respect to the rail, and therefore, the slide door is opened from the fully closed state. In some cases, the sliding door is displaced from the side of the container to the outside of the vehicle by rotating the rotating pipe, and is slid along the upper and lower rails while being separated from the side of the container. Also, when closing the slide door from the fully open state,
The sliding door is slid from the fully open position to a position covering the opening while being away from the side of the container, and at this position, the rotating pipe is rotated to displace the sliding door in the vehicle direction and close the opening. As described above, when the slide door is displaced in the vehicle direction when fully closed, the seal member interposed between the opening and the slide door is elastically deformed, and the seal is securely sealed so that the cool air in the container does not escape. You can do it. Incidentally, in such a cold storage container, in order to ensure sufficient sealing performance, the number of sealing members is increased as compared with a sliding door of a vehicle that does not have a cold storage function, so-called double sealing structure. In a structure in which the sliding pipe is rotated to displace the slide door as in the above-described conventional technique, a lever is provided on the rotating pipe, and the lever is used when the rotating pipe is rotated. By making the ratio obtainable, the sealing member can be reliably elastically deformed even with a small operating force.

[0004]

As described above, in the prior art, even if the number of sealing members is large, the sliding door can be completely closed with a light operating force when closing the sliding door. Two rotating pipes and levers are attached to the outside of the door, and the upper and lower rails are also exposed on the side of the container. The appearance is inferior and the flash surface is improved to improve aerodynamics and reduce noise. Can not be achieved. In addition, in vehicles such as insulated containers, advertisements may be displayed on the side of the container and on the sliding door. In such a case, if a rotating pipe or the like is attached to the outside of the sliding door, this may occur. Obstruct display. On the other hand, as a slide door device that does not have the above-described problem of appearance quality and can achieve a flash surface, a device applied to a general one-box car or the like is known. In this device, a bracket is provided inside the front and rear of the slide door, a roller provided on this bracket is configured to roll on a slide rail, and the front end of the slide rail is formed in a shape curved in the vehicle interior direction. Have been. In this structure, the slide rail provided at the front of the slide door on which the roller rolls is covered and concealed by the slide door, and only the slide rail provided at the rear of the slide door on which the roller rolls is located outside the vehicle when fully closed. , The appearance is excellent, and since no rotating pipe is provided outside the sliding door, it is easy to form a flash surface and display an advertisement. However,
In such a structure, the front ends of the upper and lower rails are curved in the vehicle interior direction, and the slide door is displaced in the vehicle interior direction as the rollers roll on the curved portion. Therefore, when the seal member is elastically deformed when fully closed, the seal member can be deformed only by the component force of the operating force applied to the slide door in the sliding direction. In this case, a large sliding operation force is required, and it is difficult to completely close the door. In particular, in the case of a cold storage container, it is necessary to provide a heat insulating material in the slide door in order to secure the heat insulating performance. In this case, the slide door becomes heavy, so that a larger slide operation force is required. In addition, when the weight of the slide door is heavy, a larger operation force is required when closing the door on a slope.

In addition, in the case of a cold storage container, it is preferable to make the opening as wide as possible in consideration of the workability of loading and unloading luggage. However, if the opening is widened, the required sliding amount of the slide door increases, and the length of the rear slide rail extending rearward from the opening also increases. As described above, when the length of the rear slide rail is increased, when the rear slide rail is arranged at a middle height of the opening, the rear slide rail is extended to the side surface of the container. If the rear slide rail is provided below the opening, the rear slide rail will interfere with the rear wheel tire house. Therefore, it is difficult to secure the required length of the rear slide rail, and in this case, the width of the opening is limited.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and aims to obtain a sufficient sealing property, improve sliding operability, and make a sliding surface of a sliding door flush. The main objective is to achieve all of the above, and also to achieve a flush surface on the side of the container while securing the opening area.

[0007]

A sealing member is provided between the slide door and the container to elastically deform when the slide door is fully closed to seal the inside of the container with the outside; A lock mechanism that holds the slide door in a fully closed state is directed to the inside of the vehicle and the vehicle body, and the lock mechanism is vertically extended and rotatably supported inside the slide door, A rod member integrally connected to an opening / closing handle disposed outside the vehicle, hooks provided at upper and lower ends of the rod member, and hooks provided in the container so as to be engageable with the respective hooks. The hook and the striker are engaged with each other immediately before the slide door is fully closed when the slide door is slid from the open state to the fully closed state. It becomes ability and, characterized in that it is configured to displace the sliding door in the fully closed position by the hook and the striker with the hook from the engagement state to rotate relative to each displacement. According to a second aspect of the present invention, in the slide door device for a vehicle according to the first aspect, it is preferable that the rear lower guide rail is disposed at a position higher than a wheel house of a rear wheel. Also, as described in claim 3, claim 1
Or the slide door device for a vehicle according to 2, wherein the slide door is disposed at a position where a lower end surface thereof vertically overlaps a front lower guide rail, and a lower one of the upper and lower strikers is moved in a vertical direction. It is preferable to dispose it between the lower front guide rail and the sealing material provided along the general portion of the lower edge of the opening.

(Operation) When the sliding door in the fully closed state is opened, an opening operation is performed by an opening / closing handle to rotate the rod member and the hook. It becomes slidable, and the slide door slides along each guide rail.
At this time, when sliding the curved portions of the respective guide rails, the guide rails are displaced in the vehicle exterior direction, and then slide at a position away from the side surface of the container. When closing the slide door in the open state, when the slide door is slid to the vicinity of the fully closed position, the hook of the slide door reaches a position where it can be engaged with the striker of the vehicle body. In this state, when the rod member is rotated by operating the opening / closing handle, the hook and the striker are engaged with this, and the hook and the striker are relatively rotated while maintaining this engaged state. By this relative rotation, the slide door is displaced in the forward and in-vehicle directions along the guide rail to bring the sealing material into a fully closed state while compressively deforming the sealing material. In operating the lock mechanism in this manner, the operating force applied to the slide door when fully closed can obtain an arbitrary lever ratio based on the position where the hook engages with the striker and the length of the opening / closing handle. When the reaction force due to the compression of the sealing material is large, the lever ratio is set to be large.

When the slide door is fully closed, the front upper guide rail and the front lower guide rail are covered by the slide door, and the rear lower guide rail extends rearward along the lower edge of the container. Further, in the lock mechanism, the rod member and the hook are provided in the slide door, the striker is provided on the vehicle body side at a position covered by the slide door, and only the opening / closing handle is exposed to the outside of the vehicle. Therefore, there is no member exposed on the side of the container, and only the opening / closing handle is exposed even on the sliding door, so that a flash surface can be achieved. When displaying, there is no member that hinders this.

According to the second aspect of the present invention, when the opening portion is widened to increase the sliding amount of the sliding door required for opening and closing, even if the length of each guide rail becomes long, the rear lower guide rail can be moved backward. There is no interference with the wheel house. According to the third aspect of the invention, in the vehicle body, the striker is provided at a position between the sealing material provided along the general portion of the lower edge of the opening and the front lower guide rail in the vertical direction. The shape of the part is not restricted by the position of the striker.

When the slide door SD is fully closed, the striker 9h is fixed to the vehicle body via a support member 17 at a position where it engages with a hook 9f provided at the lower end of the pipe 9a. Although the support member 17 is described as floating in the air in the figure, the support member 17 is supported by the pillar member 11 on the rear side of the opening 3. By disposing the striker 9h at a position lower than the double seal in this way, the presence of the striker 9h does not restrict the width of the lower end of the opening 3, and as shown in FIG. The width of the lower edge of the opening 3 can be increased. By the way, the upper striker 9h is arranged at a height overlapping with the horizontal extension of the general part of the double sealing materials 10a and 10b.
At the rear end of the upper edge, the height of the double sealing materials 10a and 10b is reduced at the rear end of the upper edge so as not to interfere with the striker 9h and the members supporting the striker 9h. And as a result, the upper edge of the opening 3
The width is smaller than the lower edge. The height at which the rear lower guide rail 6 is arranged is the lower edge of the side surface of the container C as described above, and does not interfere with the wheel house HH of the rear wheel shown in FIG. It is set.

In the sliding door SD for a vehicle according to the first embodiment, when the door is opened from the fully closed state, the opening / closing handle 2 shown in FIGS. 1, 2 and 5 is moved from the state where the opening / closing handle 2 is housed in the body 9b. , Rotate the car outward to pull it toward you. As a result, the pipe 9a and the hooks 9f, 9f provided at the upper and lower ends thereof rotate integrally, and the hook 9f is moved in FIG.
From the state of the solid line to the state of the two-dot chain line, the engagement with the striker 9h is released. Therefore, the sliding door SD
Is disengaged from the vehicle body, and the guide rails 4, 5, 6

Slides are made smoothly.

On the other hand, when closing the slide door SD,
The slide door SD is slid forward along the guide rails 4, 5, and 6. When the guide rails 4, 5, and 6 slide near the fully closed position, the guide rails 4, 5, and 6 are displaced inward by the curved portions at the front ends, and the tips of the hooks 9 f enter the approach space 9 j of the striker 9 h. From this state, the opening / closing handle 2 provided on the surface of the slide door SD is further turned in the vehicle body direction from the state of protruding in the vehicle exterior direction so as to be accommodated in the body 9b. Along with this,
The hook 9f rotates to engage the claw portion 9g and the engaging portion 9k, so that the slide door SD is drawn toward the inside of the vehicle to the fully closed position.
0a, 10b, 10c and 10d are compressed and deformed,
The inside of the container C and the outside air are sealed. When the sealing members 10a, 10b, 10c and 10d are compressed and deformed in this way, the elastic restoring force of these sealing members acts in a direction to push back the slide door SD. Therefore, the sliding door SD can be completely closed with a small operation force against the elasticity of the seal material. The front portion of the slide door SD is pulled inward by the curved portions at the front ends of the front upper and lower guide rails 4 and 5 and the rollers that roll the guide rails 4 and 5, and the sealing material 10a is provided. , 10b, 10c, 10d are compressed and deformed and sealed.

The appearance quality can be improved, the aerodynamic performance can be improved and the noise can be reduced by using the flash surface, and the advertisement can be displayed on the side of the slide door SD and the container C. can get.

(B) As a sealing structure of the container C, a triple sealing structure is formed over the entire periphery of the opening 3 by the sealing materials 10a, 10b, 10c and 10d, and a reaction force received by the sealing materials 10a to 10d when fully closed. Is a large structure, while a structure in which the force for displacing in the vehicle width direction is difficult to obtain as a structure for displacing in the vehicle width direction while sliding by the curved portions of the guide rails 4, 5, 6 as described above, As 9, a hook 9 f and a striker 9 h are used, and the opening / closing handle 2 and the hook 9 are used.
Since the lever ratio can be obtained based on the relationship with the length f, although a large force is required to fully close the slide door SD as described above,
It can be completely closed with a small operating force.

(C) As shown in FIG. 1, the opening 3 is formed in a substantially rectangular shape, and the upper right upper part has a protrusion at the corner to slightly narrow the opening width, but the lower part has a corner. There is no protrusion at the part, and a wide opening width can be obtained, and luggage can be easily taken in and out (shown by a solid line in the figure). The rear lower guide rail 6 is arranged at a height near the lower edge of the slide door SD so as not to interfere with the rear wheel house HH in the horizontal direction. Even if the required sliding amount of the door SD is increased, the required length of the rear lower guide rail 6 can be ensured.

(D) Since the sliding handle 1 is provided on the sliding door SD in addition to the opening / closing handle 2, the sliding operation of the sliding door SD is easy.

(Embodiment 2) Next, a sliding door device for a vehicle according to Embodiment 2 will be described. Embodiment 2

Only differences from the first embodiment will be described. explain. FIG. 8 is a longitudinal sectional view showing a lower end portion of the device according to the second embodiment, and corresponds to FIG. 7 of the first embodiment. The height at which the striker 9h is supported is the same as that of the first embodiment. Is higher than the ones. That is, in the second embodiment, the general portion 8d on the lower end surface of the inner panel 8b of the slide door SD is arranged at a position higher than the lower front guide rail 5, and the hook 9f is provided (the rear end angle). Portion) is cut or bent to form an entry space 91 for the striker 9h, and a corner lower end surface 8e is provided. The hook 9f faces the entry space 91, and the corner lower end surface 8e is Double sealing material 10a, 10
It is arranged at a height overlapping the horizontal extension of the general portion of the sealing material 10b above b. The striker 9h is arranged at a height corresponding to the position of the hook 9f so as to overlap the horizontal extension of the general portion of the lower sealing material 10a. At the rear corner of the lower end of the opening 3 corresponding to the entrance space 91, the sealing members 10a, 10
Both b are provided with inclined portions 101a, 101b (shown also by two-dot chain lines in FIG. 1) which are directed upward (increased) toward the rear. And the striker 9h,
The sealing member 10a is provided below the inclined portion 101a of the sealing member 10a below the sealing members 10a and 10b.

In short, in the first embodiment, the straight portion of the front lower guide rail 5 and the inner panel 8b of the slide door SD
So that the straight portion of the lower front guide rail 5 is disposed on the vehicle inner side of the inner panel 8b of the slide door SD, the general portion 8d on the lower end surface of the inner panel of the slide door SD is lowered, and the hook 9f The position of the striker 9h can be lowered. The straight portion of the lower front guide rail 5 was arranged inside the vehicle. The front end of the front lower guide rail 5 (the front end of the curved portion) is positioned more inward (in the center of the vehicle body) and the bracket 7b is formed longer in the inward direction. By arranging the position of the general portion 8d higher than the straight portion of the lower front guide rail 5, the straight portion of the lower front guide rail 5 does not interfere with the inner panel 8b of the slide door SD. For this reason, the lower front guide rail 5 is arranged outside the vehicle as compared with the first embodiment, and the dimension of the bracket 7b in the vehicle interior direction is made shorter. In both the first and second embodiments, the lower front guide rail 5 is used.

In the second embodiment, the opening 3 is formed in a vertically symmetric shape.

[0029]

As described above, in the sliding door apparatus for a vehicle according to the present invention, each guide rail supporting the sliding door is bent at the front end so that the sliding door moves in the vehicle width direction as the guide rail slides. With a structure that displaces
The front upper and lower guide rails are arranged at the position overlapping the slide door when fully closed, the rear lower guide rail is arranged along the lower edge of the container side, and the lock mechanism for locking the slide door is located inside the slide door. Since the lock mechanism and guide rails are arranged so that the lock mechanism and guide rail do not protrude on the surface of the sliding door and the side of the container except for the handle for opening and closing, the effect that the appearance quality can be improved is obtained, and the flash surface is obtained. It is possible to obtain an effect that the aerodynamic performance can be improved and noise can be reduced by the conversion, and further, an effect that an advertisement can be displayed on the slide door and the side of the container can be obtained. Further, as described above, the guide rail is curved to be displaced in the vehicle width direction in accordance with the displacement in the vehicle front-rear direction due to the slide, but the displacement of the slide door when fully closed is caused by the hook of the lock mechanism and the striker. Since the structure is performed by relative rotation, even if the seal material is provided in multiple layers to ensure the sealing property of the container and a large operating force is required when fully closed, the lever between the opening and closing handle and the hook Based on the ratio, a large operating force can be obtained, the fully closed state can be reliably achieved with a small operating force, and an effect that high operability can be obtained is obtained.

According to the second aspect of the present invention, since the lower rear guide rail is disposed above the wheel house of the rear wheel so as not to overlap in the horizontal direction, the length of the rear lower guide rail is smaller than that of the wheel of the rear wheel. There is no restriction by the house, and even if the opening is widened, the required sliding amount of the sliding door can be secured, and it is easy to secure the opening width of the opening, and high design flexibility is obtained. It works. According to the third aspect of the invention, in the vehicle body, the striker is provided at a position between the sealing material provided along the general portion of the lower edge of the opening and the front lower guide rail in the vertical direction. The shape of the portion is not restricted by the position of the striker, and it is possible to secure a wide opening width of the opening, and it is possible to obtain an effect of obtaining a high degree of design freedom.
