Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide type opening / closing tent which can expand and contract in a bellows type, and more particularly to a sliding type opening / closing tent which can completely open the upper part of a base frame when a tent unit is contracted. It is related.

[0002]

BACKGROUND OF THE INVENTION This type of sliding opening / closing tent has been used as a structure of a warehouse or the like on the ground or as a cover of a bed of a vehicle such as a truck or a trailer. I have. Of these, for example, when used as a cover of a cargo bed of a vehicle, a configuration is often adopted in which the tent unit expands and contracts so that the cargo on the cargo bed can be freely opened so as to more easily load and unload luggage as a storage object. In addition, Japanese Utility Model Laid-Open No. 62-124033 and Japanese Patent Application Laid-Open No. 8-259
As shown in No. 75, it has been proposed that the upper part of the base frame can be completely opened when the tent unit is contracted.

[0003] However, in actuality, when designing this type of fully open type slide-type opening / closing tent, the tent unit for opening and closing the normal storage room, the retreating operation at the time of full opening and the shift mechanism thereof, etc. Requires various ideas. For example, 62-1
In the case of No. 24033, since the extended auxiliary rail 61 and the tent unit thereon are supported by the hinge 62 and the like as shown in FIG. In another embodiment of Japanese Utility Model Application Laid-Open No. 62-124033, as shown in FIG. 9B, an auxiliary rail 61 itself is inserted into a main body fixing rail 63 in a nested manner so as to be freely retractable. However, in this case, a step occurs at a connecting portion between the auxiliary rail 61 and the main body fixing rail 63. For this reason, smooth running of the tent unit may be hindered and derailment may be caused. In practice, it is difficult to employ the tent unit, and it is expected that the drive mechanism is provided with special measures. In Japanese Patent Application Laid-Open No. Hei 8-25975, FIG.
(A) As shown in (b), since the entire rail R 'is slid, the above-mentioned actual construction is disclosed.
Although there is no problem such as the problem described above, the strength of the device that can sufficiently withstand the movement of the entire rail R 'is required, and a great disadvantage occurs in terms of manufacturing cost and the like. In general, the shift mechanism of the tent unit, its associated controller, auxiliary equipment and the like are fixedly installed as much as possible, and it is desirable to design the equipment so that it does not become movable in order to avoid various failures and the like and to perform maintenance.

[0004]

[Technical Problems Attempted to Be Developed] The present invention has been made in view of such a background, and a control mechanism and a drive mechanism are surely arranged to stabilize the operation, and the manufacturing is possible. This is an attempt to develop a sliding tent that has a completely open structure of a new tent unit that can keep costs relatively low.

[0005]

The main body fixing rail includes a fixed main body rail, and an end slide rail that is detachably connected to the main body fixed rail and is slidable in the extension direction of the rail. The main body is fixed in a state where the end slide rail supports the contracted tent unit. It is separated from the rail and slides so that it protrudes from the end of the base frame on the extension of the body fixing rail, and the end slide rail protrudes. Those comprising as a feature in that the tent unit contracted to place said base frame above by being placed is completely opened. According to the invention,
The tent unit retracts to the outside of the base frame to completely open the storage space, so that the storage space can be used to the maximum. The end slide rail is not an auxiliary one to be used only when fully opened, and also serves as a part of the rail during normal use. Therefore, there is no waste on the rails,
For example, since it is not intended to be overhangable by being nested and inserted, there is no possibility that a step is generated in the connecting portion due to the difference in the size of the rail. Therefore, there is no fear that smooth running of the tent unit is hindered or derailment is caused. In addition, since a configuration for moving the entire rail is not used, it can be implemented at a relatively low cost in terms of manufacturing cost.

After the end slide rail is completely overhanging,
The retractor is further moved rearward again and the drive frame is pulled to the overhanging side to completely open the drive frame. According to the present invention, since the tent unit is driven by using the retractor, it can be implemented relatively inexpensively and does not require a brake mechanism or the like for holding the tent unit at an arbitrary position on the rail.
In addition, since both the primary opening and the full opening can be selected, when the full opening is not required, it can be used in the state of the primary opening. In addition, since the tent unit is driven after the slide of the end slide rail is completed when the tent unit is fully opened, there is no vibration or the like generated when the end slide rail slides, and the running on the end slide rail is smooth. And no failures are induced.

Next, the rail R which is a characteristic part of the present invention
Will be described. The rail R has a cross section I as shown in FIG. 3 (b), and is provided with a main body fixing rail 3 provided in a fixed state with respect to the base frame 2 and a slidable front and rear with respect to the base frame 2 on the rear end side. And an end slide rail 4 which can be freely connected and separated from the main body fixing rail 3.
Specifically, the main body fixed rail 3 is a fixed support frame 3A.
, And the fixed support frame 3 </ b> A is fixed to the base frame 2. The end slide rail 4 is
It is fixed to a slide support frame 4A provided slidably with respect to the base frame 2. Slide support frame 4
A has a movable wheel 4a at the front end as shown in FIGS. 2, 6, and 7, and is fitted into the rear end of the fixed support frame 3A. As shown in FIGS. 3B and 3C, a support roller 46 is rotatably provided at the rear end of the base frame 2, and the slide support frame 4A is slidably supported by this. Slide support frame 4A and fixed support frame 3
The projecting ends of A are connected by rail connection frames 6 as shown in FIG. The length of the end slide rail 4 is a length obtained by adding the slide length of the end slide rail 4 to the shrinkage limit dimension of the tent unit when the tent unit is completely contracted, and the tent is further extended when the end slide rail 4 is extended. This is a length that includes extra dimensions to prevent the unit 10 from falling.

Next, the rail slide device 40 for driving the end slide rail 4 will be described. As shown in FIG. 3, a rack 41 is stretched on the lower surface of the slide support frame 4A. On the other hand, a rail drive motor M2 that can rotate forward and backward is provided at the rear part of the base frame 2, and the rail drive shaft 42 projects over the rear end face of the base frame 2 and is rotatably mounted by a bearing 43.

A drive chain 45 is stretched. With the above configuration, the rail drive shaft 42 is driven by the rotation of the rail drive motor M2, and the rack 41 meshes with the pinion 42a.
Is laterally moved, the slide support frame 4A and the end slide rail 4 fixed thereto slide and move.

As an example, a control panel 5 for controlling the rail slide device 40 and the tent moving device 30 is provided near the rear portion of the base frame 2. The control panel 5 is connected to a rail drive motor M2 and a tent drive motor M1 as output devices. Although not shown, limit switches, which are input devices, are provided at a plurality of locations on the base frame 2 to detect the positions of the tent unit 10 completely closed and fully opened, and to detect the extended positions of the end slide rails 4. A non-extended position is detected. These limit switches are also connected to the control panel 5.

The configuration of the slide-type opening / closing tent 1 according to the present invention is as described above. Next, the usage of the sliding-type opening / closing tent 1 will be described, and the details of the control structure will also be described. (1) Primary opening (shrinkage of the tent unit) When the tent unit 10 is opened from the closed state as shown in FIG.
The tent drive motor M1 is driven by a remote control switch or the like remote from the tent, and the tent unit 10 is contracted and moved backward. The tent unit 10 is shown in FIG.
As shown in (b), everything is transferred to the end slide rail 4, and is settled in the rear half of the slide rail 4 and completely contracted. When it is not necessary to completely open the tent unit 10, the storage object is unloaded in this state.

(2) Rail Slide Next, a description will be given of a case in which the upper part of the base frame 2 is completely opened by unloading and retracting the storage object only by contracting it to the primary opening state is not sufficient and obstructive. Operate the switch again to completely open. As a result, the rail drive motor M2 is driven, and the end slide rail 4 slides rearward as shown in FIG. At this time, since the tow chain 33 is stopped, the drive frame 12 of the tent unit 10 connected to the tow chain 33 is stopped at that position, while the fixed end frame 13 is moved backward by the end slide rail 4. Pulled. That is, in the first release, the drive frame 12 was pulled open.
In this step, as a result of extending the end slide rail 4 rearward, it is equal to pulling the fixed end frame 13 and slightly expanding the tent unit 10. As a result, when the end slide rail 4 projects rearward as shown in FIG. 6C, the tent unit 10 is in a slightly extended state. At this time, a notch portion of the rail R is formed between the main body fixing rail 3 and the end slide rail 4, but by setting the length of the end slide rail 4 as described above, the tent unit 10 It is extended while it is resting on the slide rail 4.

(3) Completely Open When fully opened, the extended tent unit 1
The traction chain 33 is moved to the fully open side of the tent unit 10 and the drive frame 12 is moved in accordance with FIG.
As shown in (d), it is drawn to the fixed end frame 13. As a result, the tent unit 10 contracts again, retreats all the tent units 10 onto the end slide rails 4 protruding rearward of the base frame 2 on the end slide rails 4, and completely opens the upper part of the base frame 2. I do.
In addition, the movement of the towing chain 33 will be described. In the case of the primary opening, the towing element 33a is positioned almost in front of the rear end of the base frame 2 by the shrinkage allowance of the tent unit 10, and stops.
When fully opened, it moves from that position to almost the rear end. Since the retractor 33 a is attached to the drive frame 12 of the tent unit 10, the rear thereof is contracted and supported on the outer end slide rails 4 of the base frame 2.

An example of a control mode for driving the tent unit 10 and the end slide rail 4 at the time of complete opening described above will be described in detail. First, when the tent unit 10 is completely contracted when the tent unit 10 is fully opened, a limit switch for detecting complete contraction provided on the slide support frame is brought into contact with the drive frame 12 to detect the complete contraction state, and the tent drive motor M1 is detected. Stop driving. In addition, when the rail slides and completely opens, when the end slide rail 4 projects rearward of the base frame 2, for example, a limit switch for detecting the complete extension of the end slide rail 4 detects this overhang, and the rail is driven. Motor M2
Is stopped, and the driving of the tent driving motor M1 is started. Then, in a state where the tent unit 10 is completely contracted, this state is detected by the limit switch for detecting the complete contraction, and the driving of the tent drive motor M1 is stopped.

In the above-described embodiment, the end slide rail 4 is completely extended to the rear of the base frame 2 when the tent unit 10 is fully opened because the tent unit 10 is excellent in stability when traveling on the rail R. , The drive of the tent drive motor M1 is started, and the tent unit 10 is completely contracted rearward.
Immediately after the start of the driving of the tent drive motor M1, the expansion slide of the end slide rail 4 in FIG. 6C and the complete contraction movement of the tent unit 10 in FIG. Modifications may be made so that they are performed almost simultaneously. In this case, care should be taken that the sliding speed of the drive frame 12 of the tent unit 10 does not exceed the sliding speed of the end slide rail 4. In this case, if the sliding speed of the end slide rail 4 at the time of the complete contraction causes a disadvantage that the speed at the time of the primary opening becomes slow, a variable speed motor is applied as the tent drive motor M1. Alternatively, the speed of the tent unit 10 at the time of primary opening may be high, and the speed at the time of full opening may be low. The method of substantially simultaneously sliding the end slide rail 4 and the drive frame 12 of the tent unit 10 can be applied to the extension of the tent unit 10 described in the next section.

(4) Closing (Extension of Tent Unit) Next, the case of closing the tent unit 10 which has been completely opened will be described. Basically, an operation reverse to the above-described opening operation is performed. That is, the tent unit 10 which has been completely contracted is extended to the vicinity of the end of the end slide rail 4 as shown in FIG. Next, the end slide rail 4 is slid and connected to the rear end of the main body fixing rail 3 as shown in FIG. Next, by operating the remote control switch or the like again, the tent unit 10 is extended as shown in FIG. 7D, and the drive frame 12 is moved to the front end of the base frame 2 to completely close the upper surface of the base frame 2. In a state where the tent unit 10 does not protrude to the rear of the base frame 2 in this manner, the tent unit 10 is compact as a whole, and a large number of slide-type opening / closing tents 1 can be stored in a narrow range, which is convenient.

[0029]

Other Embodiments Although the basic embodiment of the present invention is as described above, various other modifications can be made. That is, in the above-described embodiment, the shift mechanism and the like are fixed,
Although it is devised so as not to be movable, in the following embodiment, the tent moving device 30 is a movable self-propelled type. That is, FIG. 8A shows an embodiment in which the drive motor M3 is provided directly on the drive frame 12 for driving. In the opening / closing mode in this case, for example, when completely opening from a completely closed state as shown in FIG. 8B, the tent unit 10 is first completely contracted and first opened as shown in FIG. 8C. Next, as shown in FIG. 8D, the end slide rail 4 is slid and protruded rearward. At this time, drive frame 1
Since the tent unit 2 is not fixed to the base frame 2 via the traction chain 33, the tent unit 10 remains completely contracted, thereby completing the complete opening. When closing, the reverse of the opening operation is performed. In the case of this self-propelled type,
There is a problem that the drive frame 12 runs due to the inertial force. To stop the drive frame 12 at a predetermined position, a separate brake or rail holding mechanism is required. Further, in order to prevent the main body fixed rail 3 and the end slide rail 4 from dropping between the gaps of the rail R when the rail slides due to unexpected inertia running, it is necessary to provide a complicated safety mechanism. However, the shift mechanism and the like can be simplified.

In the above-described basic embodiment, the switch operation is performed a plurality of times to completely open and completely close the tent unit 10. However, the fully opened and completely closed is performed by such a plurality of operations. Alternatively, a sequence circuit or the like may be provided so as to selectively perform whether to completely open and completely close by one operation. That is, in the case of such a configuration, for example, the tent unit 1
In order to perform the full opening from the time of closing the 0, an operation of a one-touch switch or the like for the full opening may be performed. Further, when it is sufficient to perform only the primary opening without performing the full opening, an operation of a stage switch for the primary opening may be performed.

As a basic embodiment, the rail slide device 40 has a structure in which it slides using a rack 41 and a pinion 42a. However, the rail slide device 40 may be appropriately changed to various other known slide mechanisms such as a ball screw mechanism and a cylinder. It is also possible to carry out.

Although the tent unit 10 is one-sided in the basic embodiment, for example, the tent unit 10 may be configured to be opened from both sides from the center or the like. In such a case, the end slide rails 4 are provided at both ends of the base frame 2.
It is preferable that the tent unit 10 divided into two is supported on the end slide rails 4 projecting from both ends of the base frame 2 when the base frame 2 is fully opened.

According to the slide type opening / closing tent having a completely open structure of the tent unit, the rail R is separated from the main body fixing rail 3 fixed to the base frame 2 and separated from the main body fixing rail 3. The tent unit 10 is retracted to the outside of the base frame 2 to completely open the storage space because the tent unit 10 is composed of the end slide rail 4 which is freely connected and is slidable in the direction of extension of the rail R, thereby maximizing the use of the storage space. it can. The end slide rail 4 is not an auxiliary member used only when it is completely opened, and is used as a part of the rail R even during normal use. Therefore, rail R
In addition, since there is no waste, and for example, it is not made to be overhangable by being nested, no difference in the size of the rails R causes a step at the connecting portion. Therefore, there is no fear that the smooth running of the tent unit 10 is hindered or derailment is caused. In addition, since the configuration for moving the entire rail R is not taken, it can be implemented at a relatively low cost in terms of manufacturing cost. When it is not completely open, it is compact overall, so it can be easily transported to narrow places,
The mounting space can be relatively small.

According to the slide type opening / closing tent having a completely open structure of the tent unit, the slide support frame for supporting the end slide rails 4 instead of inserting them into the main body fixing rails 3. 4A and the fixed support frame 3A are inserted into either one of the end slide rails 4 or the main body fixed rails 3.
Is not hollow and has high strength, and there is no difference in the size of the connecting portion between the end slide rail 4 and the main body fixing rail 3 so that a step does not occur at the connecting portion. In addition, since the connection is not made by a hinge or the like, the end slide rail 4 at the time of overhanging is rich in strength.

According to the slide type opening / closing tent having the completely open structure of the tent unit according to the third aspect, the retractor 3
Since the tent unit 10 is driven using the 3a, a relatively inexpensive implementation can be performed, and a brake mechanism or the like for holding the tent unit 10 at an arbitrary position on the rail R is not required. In addition, since both the primary opening and the full opening can be selected, when the full opening is not required, it can be used in the state of the primary opening.

According to the slide type opening / closing tent having the completely open structure of the tent unit according to the fourth aspect, the retractor 3 is provided.
Since the tent unit 10 is driven using the 3a, a relatively inexpensive implementation can be performed, and a brake mechanism or the like for holding the tent unit 10 at an arbitrary position on the rail R is not required. In addition, since both the primary opening and the full opening can be selected, when the full opening is not required, it can be used in the state of the primary opening. In addition, since the tent unit 10 is driven after the slide of the end slide rail 4 is completed when the tent unit 10 is completely opened, there is no vibration or the like generated when the end slide rail 4 slides. The vehicle travels smoothly and does not cause a failure or the like.

According to the slide type opening / closing tent having a completely open structure of the tent unit according to the fifth aspect, the tent unit 10 is driven by using the traction band such as the traction chain 33, so that the tent unit can be easily and smoothly opened and closed. It can be done, and a relatively inexpensive implementation can be made. Further, a brake mechanism or the like for retaining the tent unit 10 at an arbitrary position on the rail R is not required. Also, since both primary opening and full opening can be selected, when full opening is not necessary,
Can be used in the primary open state.

Further, in the slide type opening / closing tent having a completely open structure of the tent unit according to claim 6, the traction band is a chain, and the driving wheel and the driven wheel are sprockets. Slip or the like does not occur between the driving wheel and the tent unit 10, and the tent unit 10 can be reliably stopped at an arbitrary position.

According to the slide type opening / closing tent having the completely open structure of the tent unit, the length of the end slide rail 4 is set to the width of the tent unit 10 when the tent unit 10 is completely contracted. Is extended to the length obtained by adding the slide length of the tent unit 10 to the tent unit 10 so that the tent unit 10 does not fall when the end slide rail 4 is extended. The tent unit 10 can be contracted and moved, and there is no waste that the size of the end slide rail 4 is too long. Also, since it has a marginal dimension, it can be used when the end slide rail 4 is overhanging, etc.
The tent unit 10 does not fall into the notch of the rail R.

According to the slide type opening / closing tent having a completely open structure of the tent unit according to the eighth aspect, the tent drive shaft 34 projects laterally from the rear end of the base frame 2 so as to extend rearward. The tent unit 10 can be reliably moved backward.
