[Detailed description of the invention] The present invention relates to a slide roof opening/closing device for a transport box, and in particular, a movable slide roof is provided on the roof of the transport box, and the movement of the slide roof allows the roof to open and close. This relates to a structure that has a large opening for convenient loading and unloading of baggage.

This type of sliding roof opening/closing device is provided with guide rails on the upper sides of opposing side walls of a van-type vehicle such as a van-type truck or a van-type trailer, or a transportation box such as a container, and the sliding roof opening/closing device is installed along the guide rails. By moving a slide roof that constitutes at least a part of the roof portion of the box,
The roof part on which the sliding roof is installed is made to open and close, and various structures have been proposed in the past.
Publication No. 41302, Publication No. 51-26405, Publication No. 53 of Utility Model Publication
-123714 publication, Utility Model Application Publication No. 55-31722, etc.
An example of this has been revealed.

However, with these conventional sliding roof opening/closing structures, in order to prevent rainwater from entering the box and cold air escaping from the box,
When closing a roof opening with a sliding roof, the structure must be such that a sealed structure is formed, while when opening such a roof opening, it is necessary to move the sliding roof in the longitudinal direction. As a result, their structures are generally complicated and their operation is troublesome. For example, when moving a sliding roof, in the case of a conventional device that moves the sliding roof while slidingly contacting a sealing member for forming an airtight structure, due to the frictional resistance caused by this sliding contact, A great deal of effort is required to open the sliding roof. Furthermore, with conventional devices that lift the sliding roof upward and then move it, the problem of operability due to frictional sliding as described above does not occur; Since independent mechanisms are used for each movement, the structure of the upper part of the side wall becomes extremely complicated, and a special complicated structure is required to move the sliding roof in the front and back direction in the raised state. The adoption of a new structure is also required.

The present invention was developed against this background, and its purpose is to provide a slide with a simple structure that allows the sliding roof to be moved extremely lightly and easily. An object of the present invention is to provide a roof opening/closing device.

In order to achieve this object, in the present invention, guide rails are provided at the upper portions of the opposite side walls of the transport box, and at least one part of the roof portion of the box is run along the guide rails. In a device for opening and closing a roof portion on which a sliding roof is provided by moving a sliding roof that constitutes a part of the roof, rollers that engage with and slide on the guide rails are provided on both sides of the sliding roof. A plurality of attached links are pivotally connected to each other, and the links located on at least each side of the slide roof are connected via a predetermined connecting rod so that the links can be simultaneously rotated about the rollers as a rotation center. At the same time, by providing at least one of the links located on each side of the sliding roof with an auxiliary roller that can engage and slide on the guide rail by rotating around the roller, the link The slide roof raised by the rotation around the rollers can be moved while being supported by the rollers engaged with the guide rail and the auxiliary rollers, and when the roof portion is closed by the slide roof. An auxiliary roller guide rail is provided on the guide rail portion of the link at the auxiliary roller position, and extends integrally upwardly or downwardly from the guide rail, so that the auxiliary roller is moved away from the guide rail when the sliding roof is closed. The sliding roof is guided by the auxiliary roller guiding rail and allowed to rotate around the rollers of each link, thereby allowing the sliding roof to be lowered.

Therefore, according to the present invention, the slide roof is raised or lowered by the rotation of a plurality of links provided on both sides of the slide roof, and the rollers that are the rotation centers of the links are aligned with the guide rail. By being guided and moved by the slide roof, the slide roof can be easily moved, and by the rotation of the link,
The auxiliary roller to which the link is attached is made to be able to engage and slide on the guide rail, so that the auxiliary roller that is engaged with the guide rail and the roller that is the center of rotation of the link can cause the slide to slide. Since the roof can be moved while being supported, it becomes possible to effectively hold the raised sliding roof in that state and easily move it, and the structure is also extremely simple.

In addition, when the roof section is closed by the sliding roof, an auxiliary roller guide rail is provided that extends integrally from the guide rail to correspond to the auxiliary roller position at that time. The lowering position of the slide roof is determined from the point where the slide roof is guided smoothly by the roller guide rail, allowing each link to rotate around the rollers, and the lowering position of the slide roof is determined. This allows for easy and reliable closure.

Hereinafter, in order to clarify the present invention more specifically, embodiments according to the present invention will be described in detail based on the drawings.

First, FIGS. 1 and 2 show an entire van-type truck equipped with an example of a sliding roof opening/closing device according to the present invention, in which a luggage compartment 2 is disposed at the rear of the van-type truck. The roof portion thereof is composed of a fixed roof 4 and a sliding roof 6. By moving the slide roof 6 in the longitudinal direction of the vehicle (horizontal direction in the figure), the roof portion where the slide roof 6 is provided is opened wide, making it easy to load and unload luggage into the luggage compartment 2. It is designed to be.

As is clear from FIGS. 3 and 4, on both sides of the sliding roof 6, there are a plurality of approximately right-angled triangles (in this case, two
2) links 8 are pivotally connected at their non-perpendicular corners, and main rollers 10 are attached to the perpendicular corners of the links 8; The front and rear links 8, 8 located on the same side of the slide roof side are connected by a connecting rod 12, and the front and rear links 8 are connected by moving the connecting rod 12 in the axial direction. , 8 are rotated around their respective main rollers 10, and the fourth
As shown in the figure, the sliding roof 6 can be raised. Note that a tension spring 14 is stretched between the slide roof 6 and the front link 8, and its biasing force applies to the link 8 and other links connected by the connecting rod 12. The links 8 are given the ability to rotate around their respective main rollers 10, so that the slide roof 6 can be easily raised. Also, links 8 located at the rear on each side of the sliding roof 6
are provided with auxiliary rollers 16 similar to the main rollers 10, located between the main rollers 10 and the pivot points of the connecting rods 12, respectively.

On the other hand, as is clear from Figures 5 to 7,
At the upper end of each side wall 18 of the luggage compartment 2, an inverted C-shaped (in the figure) guide rail 20 extending in the front-rear direction of the luggage compartment 2 is disposed. The attached main roller 10 and auxiliary roller 16 can be engaged and slid. Further, at the rear end of the guide rail 20, as shown in FIGS. 3 and 4, the guide rail 20 is
An arc-shaped auxiliary roller guide rail 22 is provided which is integrally formed with and extends in a downwardly curved manner. More specifically, the radius of curvature of the auxiliary roller guide rail 22 is approximately equal to that of the main roller 10 and the auxiliary roller 16.
is made equal to the distance between By moving the slide roof 6, the slide roof 6 is lowered.

Further, as shown in FIGS. 5 and 6, a deep groove 24 is provided inside the upper part of the side wall 18 of the luggage compartment 2 located at the roof portion that is opened by the movement of the slide roof 6. When the sliding roof 6 is lowered, it is possible to accommodate the links 8, the connecting rods 12 and also the tension springs 14, which are also lowered. Further, as shown in FIG. 7, a shallow groove 26 for accommodating the guide rail 20 is provided in the upper part of the side wall 18 located in the fixed roof 4 portion. Drain holes 28 and 30 are provided in the respective grooves 24 and 26.
are provided for each. Furthermore, as shown in FIG. A double sealing mechanism is formed by pressing the second seal 36 attached at the bottom against the upper end surface of the inner side wall portion forming the groove 24.

Therefore, in the luggage compartment 2 having such a structure, when the roof opening is closed by the sliding roof 6 as shown in FIG. rotates downward around the main roller 10, and the auxiliary roller 16 is positioned within the auxiliary roller guide rail 22, whereby the front and rear links 8,
The connecting rod 12 connecting the links 8 is located at the lowest position, and the tension spring 14 applies the largest tensile force to the link 8 by stretching it.

In this state, the seal between the roof opening and the sliding roof 6 is a double seal formed by the first and second seals 34 and 36 in the width direction, as shown in FIG. At the front end portion of the sliding roof 6, a seal 38 provided there is attached to the fixed roof 4.
This is achieved by being pressed against the rear end of the slide roof 6, and furthermore, since the rear part of the slide roof 6 is the door header part 40, it is pressed against the door header part 40. By attaching a door provided on the rear wall of the luggage compartment, for example, a double door door 42, a seal similar to the conventional one is formed there, thereby completing the seal around the roof opening. .

In order to open the roof opening closed by the sliding roof 6, the locking rod 44 that locks the door 42 is removed from the cam 46 provided on the header portion 40, and a suitable means is used. Pull the connecting rod 12 rearward, or pull the connecting rod 12 backward, or
By lifting the entire body obliquely upward, the auxiliary roller 16 slides within the auxiliary roller guide rail 22 and is guided to the guide rail 20, and each link 8 is moved counterclockwise in FIG. 10, resulting in the state shown by the solid line in FIG. At this time, the tensile force of the tension spring 14 assists the rotation of the link 8 around the roller 10, and allows the slide roof 6 to easily move upward to the state shown in FIG. 4.

The slide roof 6, which has been raised as shown by the solid line in FIG.
The roof opening is moved to the position shown by the two-dot chain line, and the roof opening is opened. Note that when the slide roof 6 moves forward, the link 8 that supports the slide roof 6 has a main roller 10 and an auxiliary roller 16 located at the rear thereof, and the link 8 that supports the slide roof 6 has a main roller 10 and an auxiliary roller 16. Therefore, the rear link 8 cannot rotate around the roller 10, and at the same time, the front link 8 connected to it by the connecting rod 12 cannot be rotated, so it cannot slide. The roof 6 can then be effectively held in the raised position.

In addition, when closing the roof opening with the slide roof 6, the procedure is reversed to the above, but when the slide roof 6 reaches the closing position of the roof opening (the fourth Since the auxiliary roller guide rail 22 is present at the position of the auxiliary roller 16, the auxiliary roller 16 is easily guided into the auxiliary roller guide rail 22, and therefore the rotation around the roller 10 is The link 8 can be easily caused to rotate, the slide roof 6 can be lowered, and the roof opening can be effectively closed by the slide roof 6. Moreover, like this, the guide rail 20
The auxiliary rollers 16 that have slid while engaging with the roof opening are effectively guided into the auxiliary roller guide rail 22 only in the closed position of the roof opening. For example, the closing position of the roof opening can be uniquely determined, thereby providing the advantage that the closing operation of the roof opening can be performed reliably and accurately.

In this way, the sliding roof 6 of such an embodiment
According to the opening/closing mechanism shown in FIG. 10 and auxiliary rollers 16 while rolling these rollers 10 and 16 within the guide rail 20, the roof opening can be opened and closed smoothly and easily, and the structure is In the above example, by simply adopting a structure such as providing the auxiliary roller 16 on the link 8 or forming the auxiliary roller guide rail 22 integrally with the guide rail 20, the sliding roof 6 can be raised as described above.
It can be effectively moved down and further forward and backward, and has a significantly simple structure.

In addition, according to the structure of the above example, the slide roof 6 moves upward in parallel (raises) and slides (moves) after the seal is separated, so the movement is light, and on the other hand, when closed, it moves downward. Because it closes by moving parallel to the air, the seal tightly adheres to the door, increasing its airtightness, effectively preventing the leakage of cold air inside, and the intrusion of rainwater and moisture. The biasing action of the tension spring 14 also provides the advantage that the slide roof 6 can be easily moved up and down. In addition, since the amount of lift of the sliding roof 6 can be increased, it is possible to form a heat insulating layer on the roof, and this can be effectively carried out even when the thickness of the roof becomes thick. If the header part 40 of the door 42 on the rear wall of the rear end of the roof 6 is integrally formed, the header part 40 can also be integrally moved and removed when the slide roof 6 moves. Therefore, there is an advantage that loading luggage into the luggage compartment 2 from the rear becomes extremely easy.

Note that the door 40 provided on the rear wall of the luggage compartment 2
Unlike the above example, as shown in FIG.
8, and the header portion 48 can be rotated around one end thereof so as to be moved out of the way when loading and unloading cargo.

Furthermore, in the structure of the above example, the guide rail 20 is formed into an inclined part with the left and right sides of the lower part thereof rising, and the main roller 10 is engaged with and slid thereon.
Although the structure is such that the lateral displacement of the auxiliary roller 16 is effectively prevented and stable sliding is possible, the structure shown in FIGS. 9, 10 and 11 also
Guide rails 50, 52, 5 as shown in the figure.
4 and the structure of the rollers 56 and 58, similar effects can be achieved.

Further, FIGS. 12 to 15 show a transportation box 60 provided with another example of the sliding roof opening/closing device according to the present invention. In the structure of this embodiment, parts similar to those in the above example are given the same numbers and detailed explanations are omitted, and only the different parts will be mainly pointed out. In short, the major difference between this embodiment and the previous embodiment is that the guide rails 62 extending in the front-rear direction of the box body 60 are arranged on both sides of the roof portion, in other words, in the box body. 60 is attached to the upper end of the side wall. Therefore, all the mechanisms for raising, lowering, and even moving the slide roof 6 in the front and back directions are connected to the box body 60.
It is exposed to the outside. An upwardly curved auxiliary roller guide rail 64 is integrally provided at the rear end of the guide rail 62.
The main roller 1 is engaged with and slid on the guide rail 62 and the auxiliary roller guide rail 64.
0, L-shaped rear links 66 with auxiliary rollers 16 attached are arranged on both sides of the slide roof 6, and they are fixed to both ends of the shaft 68,
This shaft 68 is attached to the upper surface of the slide roof 6 by a mounting member 70 that pivotally supports it. Further, a straight front link 72 is located at the front side of the slide roof 6, and a roller 10 (not shown) similar to the previous example attached to one end thereof is engaged with the guide rail 62. , and a shaft 74 is attached to the other end thereof, and this shaft 74 is attached to the upper surface of the slide roof 6 by a mounting member 76 that pivots the shaft 74.

A connecting rod 78 connecting these two front and rear shafts 68, 74 is connected to a lever 8, respectively.
Furthermore, a tension spring 14 is stretched between the connecting rod 78 and the upper surface of the slide roof 6, and is positioned at the center of rotation of the link 66 and furthermore the link 72. Rotating motion around the main roller 10 is provided.

Therefore, in a device having such a structure, by moving the connecting rod 78 forward in the axial direction, the respective links 66, 72
A rotational force is generated around the rollers 10, and as a result, the slide roof 6 is lifted upward as shown in FIG.
Then, it is forced to move forward. As the slide roof 6 rises in this manner, the auxiliary roller 16 attached to one end of the L-shaped rear link 66 is guided from the auxiliary roller guide rail 64 to the guide rail 62, and is moved forward. By being pushed away, the slide roof 6 can be effectively held in the raised state under the support of the main rollers 10 and the auxiliary rollers 16.

The present invention is not to be construed as being limited to the specific examples illustrated above, and various changes, modifications, improvements, etc. can be made based on the knowledge of those skilled in the art without departing from the spirit of the present invention. However, the present invention includes all such aspects within its scope. For example, as is clear from the specific example described above, the links (8, 66, 72), which are important for raising, lowering, and even moving the sliding roof, can take various shapes and The placement position is also sliding roof 6
Appropriate positions on both sides are selected.
