DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction machine or an agricultural machine for performing outdoor work, which comprises a sunshade roof provided above a driver's seat of a vehicle and a support column for supporting the roof, and the roof is movable up and down. This is related to the canopy configured as described above.

[0002]

2. Description of the Related Art Conventionally, there is a canopy, such as a construction machine or an agricultural machine which performs outdoor work, provided with a sunshade roof provided above a driver's seat of a vehicle and a support column for supporting the roof.

A flat roof indicated by 51b in FIG. 6 constitutes a sunshade, and the roof 51b is supported by columns 51a (in FIG. 6, key-shaped columns 51a are provided in pairs) and canopy. 51 are constituted.

[0004] The roof 51b is provided so as to protect the work driver from direct sunlight and to prevent rain from being directly applied to the work driver.

In FIG. 6, reference numeral 60 denotes an excavator, 60
a is a shovel car body, 53 is a seat 53a, an operation lever 53b, a lock lever 53c, and an operation panel 53d.
And a key 52, a driver's seat 61, and an arm 61 respectively.

The shovel car 60 is transported by being mounted on a trailer or the like in a compactly folded shape as shown in FIG. 6 so that the arm portion 61 does not hinder the transport.

Here, since the height of the canopy indicated by L2 in FIG. 6 is much higher than the height L3 of the arm portion 61, the protruding L1 of the canopy is used in a city center where the height is limited. However, there is a problem that it is difficult to convey it significantly.

In recent years, therefore, a canopy has been proposed which includes a sunshade roof provided above a driver's seat of a vehicle such as a construction machine or an agricultural machine, and a support column for supporting the roof, and the roof is configured to be movable up and down.

Among them, in Japanese Patent Application Laid-Open No. Hei 8-72743 and Japanese Utility Model Laid-Open Publication No. Sho 59-125568, it is devised that the support 51a is simply folded or removed. I have.

In such a conventional configuration, the roof protects the work driver from sunlight, rain, and the like, and also facilitates transportation by simply folding the support portion 51a.

On the other hand, Japanese Utility Model Laid-Open Publication No. Hei 6-14253 proposes that a roof of a canopy is used to prevent rain from directly hitting a driver's seat at a lower end position.

[0012]

In the above-described conventional fixed canopy configuration, a work canopy whose position is fixed is protected from sunlight and rain, etc., and is extremely effective in that it can be configured at a very low cost. Met.

However, after the work is completed, the work is left at a construction site or the like, and the projecting space indicated by L1 in FIG. 6 is extremely large so that the work can be easily performed. 53a etc.
It has a problem that it is easily damaged by exposure to ultraviolet rays of sunlight, wind and rain, dust at a construction site, and the like.

That is, since the instrument section and the seat are damaged earlier than the main apparatus section, the life of the apparatus cannot be obtained, and it is necessary to extend the life of the apparatus by performing maintenance and replacement, which increases the running cost. There was a problem.

Further, if there is wind and rain before the start of the work, the seat and the operation part are covered with mud, so that the work cannot be started without cleaning.

In the case of Japanese Patent Laid-Open Publication No. Hei 8-72743 and Japanese Utility Model Laid-Open Publication No. Sho 59-125568, which have a structure in which the column 51a is folded or removed, the height of the canopy can be simply reduced. However, the configuration is not always satisfactory in terms of extending the life of the instrument section and the seat.

In other words, a structure that simply bends easily to suppress the height does not prevent rainwater from penetrating, which is a problem in extending the life of the device. In addition, it is not possible to prevent deterioration of the device due to ultraviolet rays or the like. Was.

On the other hand, Japanese Unexamined Utility Model Publication No. 6-14253 discloses a construction in which a roof of a canopy is used to prevent rain from directly hitting a driver's seat at a lower end position.

In this configuration, the ingress of rainwater is prevented,
It is possible to prevent the equipment from being deteriorated by ultraviolet rays or the like.

However, the seat 53 shown in FIG.
The protrusions of the driver's seat 53 such as the control lever 53a and the operation lever 53b obstruct the roof 51b, so that even an outside person can easily insert his / her hand into the cover and operate the operation lever 53b. 53b, 53c and the operation panel 53d can be operated and the key 52 can be inserted, and if left unattended at a construction site at night, equipment may be damaged or lost due to mischief or theft of the instrument, or the machine (vehicle) itself may be stolen. And so on.

Therefore, the driver's seat can be easily protected from the weather and ultraviolet rays, the life of the equipment can be extended, and the equipment can be easily transported at a low cost.
There was a need for a canopy that could handle pranks and theft.

It is an object of the present invention to provide a canopy which is easy to transport, inexpensive and easy to handle, while protecting the driver's seat from wind and rain and ultraviolet rays.

It is another object of the present invention to provide a device for preventing mischief in a driver's seat and theft of equipment.

The bending portion 7 of the column 3 is fixed at the substantially bent end positions P and Q, and the roof 2 covers the driver's seat 4 at least at the lower end position Q of the roof at an upper position near the driver's seat 4. A key lock means 9 for fixing the roof position at the lower end position Q is provided.

Further, the inner roof 20 is formed on the lower surface 2a of the roof and has a smaller surface width than the roof 2 and is stored substantially parallel to the lower surface 2a of the roof. And a connecting means 11 which can move vertically in conjunction with the roof.

Further, the column 3 which is configured to be able to flex freely,
An elastic force accumulating means 10 for accumulating elastic force at the time of refraction (Q direction position) and releasing elastic force accumulated at the time of extension (P direction position) is provided. The storage and release are configured to operate by a slide mechanism 8 provided at a position 6 near the center of the column 3.

A transmission section 11 provided at a roof lower surface position 2a for reversingly transmitting the rotation direction R of the pivot shaft of the upper end connecting section 5a of the column 3 which can be freely extended in the S direction, and a transmission. When the roof is lowered by receiving the rotation transmission power (rotation in the S direction) of the section 11 (operation in the Q direction)
And a side roof 12 that rotates from the lower surface 2a of the roof to the side surface 2b of the roof in conjunction with.

Next, the canopy device 1 with the anti-theft function according to the second embodiment shown in FIGS. 4 and 5 is replaced with the side roof of the first embodiment, and is connected to the upper end of the column 3 which is configured to be extensible. A transmission unit 11 provided at a roof lower surface position 2a for transmitting the rotation direction R of the pivot shaft 5a in the S direction in reverse, and a rotation transmission power (S
And the inner roof 13 is displaced from the lower surface 2a of the roof to the lower side V of the roof in conjunction with the lowering of the roof (operation in the Q direction) in response to the rotation of the driver seat 4 at the lower end position Q of the roof. The operation surface 4d of the driver's seat portion 4 is protected by fitting the projections 4a to 4c.

(Operation) With the above configuration, the present invention can perform the following operation. That is, the pair of struts has a bending portion pivotally connected at a position near the center of the column so as to be swingable in the direction of the opposing column at the both ends connecting portion of the column, and the bending portion is vertically moved. Since the slide mechanism that slides and supports the vertical connecting part in the swinging direction is provided, the roof can be moved up and down in a very easy and simple structure by the bending operation of the bending portion of the column that is slid and supported by the slide mechanism. The roof can cover the driver's seat and the position above the driver's seat where the operation panel is installed.
By performing key lock at the lower end position of the roof covering the driver's seat, the driver's seat can be protected.

Therefore, in the canopy having the above structure, the roof at the lowered position can be easily transported, and the driver's seat can be protected from the wind and rain and ultraviolet rays even when left at the construction site.

Also, the column, which is configured to be freely bendable, has elastic force accumulating means for accumulating elastic force at the time of bending and releasing elastic force accumulated at the time of extension, and the elastic force of the elastic force accumulating means is provided. If the accumulation and release of the work is effected by the slide mechanism provided near the center of the support,
Since the roof's own weight can be canceled by the elastic force of the elastic force accumulating means, the roof can be easily moved up and down.

If the elastic force acts on the slide mechanism provided near the center of the column, the elastic force accumulation / release range is provided at the center without providing the entire roof movable range. It is sufficient to provide an accumulation release area in a half area of the slide mechanism, and the elastic force accumulation means can be reduced in size and simplified.

Further, a transmission portion provided at a lower surface position of the roof for transmitting the direction of rotation of the pivot shaft of the upper end connecting portion of the column which is configured to be freely reversible, and receiving the rotational transmission power of the transmission portion. A side roof that rotates from the lower surface of the roof to the side of the roof when the roof descends, and if the lower side of the roof protects the side of the driver's seat, rotates in conjunction with the bending operation The side roof can be moved from the roof lower surface to the roof side surface by the transmission power of the transmission unit.

In this side roof, since protrusions in the driver's seat such as a seat and an operation lever hinder the lowering of the roof and the lower end position of the roof is restricted, the side of the side of the driver's seat protruding sideways. The roof is used to cover the driver's seat.

As described above, when the roof is lowered, the side roof is opened from the lower surface of the roof in conjunction with the downward movement, and when the roof is raised, the side roof is interlocked and stored in the lower surface of the roof in accordance with the upward movement. The side roof can be opened and closed automatically without having to be individually opened and closed, so it is inexpensive and easy to handle, and the side roof linked to the transmission is secure because it does not fall loose due to vibration or impact and falls. .

On the other hand, a transmission portion provided at a lower surface position of the roof for reversing and transmitting the rotation direction of the pivot shaft of the upper end connecting portion of the column which is configured to be able to be bent, and receiving the rotational transmission power of the transmission portion. An inner roof that is displaced downward from the lower surface of the roof in conjunction with the lowering of the roof and protects the operating surface of the driver's seat by engaging the protrusion on the driver's seat at the lower end of the roof Then, the inner roof can be moved from the lower surface of the roof to the lower side of the roof by the transmission power of the transmission unit that rotates in conjunction with the bending operation.

In the inner roof, projections in the driver's seat such as a seat and an operation lever hinder the lowering of the roof, thereby limiting the lower end position of the roof. Then, for example, the inner roof is lowered to the operation surface to cover and protect the operation surface of the driver's seat.

As described above, when the roof is lowered, the inner roof is lowered from the lower surface of the roof in conjunction with the lowering, and when the roof is raised, the inner roof is stored in the lower surface of the roof in conjunction with the rising. The inner roof can be opened and closed automatically without being manually opened and closed individually, so it is inexpensive and easy to handle.In addition, the inner roof linked to the transmission does not loosen due to vibration or impact, so it is safe from falling down It is.

By providing the above-mentioned internal roof, the present invention can perform the following characteristic actions. That is, a member having a smaller surface width than that of the roof 2 and being stored substantially parallel to the roof lower surface 2a.
0, and a connecting means 11 that receives the movable power to move the roof 2 up and down and moves the inner roof 20 up and down in conjunction with the inner roof 20 below the roof. An internal roof such as a side roof or an inner roof can be automatically set therein via the connecting means 11. This means that it is necessary to take a lot of trouble (multiple operations using tools) on a roof with a configuration that makes it difficult for one person to work, lower the roof, and set the internal roof separately. (Release-Push-Lock) can complete the work, so it is very difficult to extend the life after completion of the work. There is also a feature that can be applied.

That is, when the key is locked at the roof lowering position, the side roof and the inner roof have the above configuration regardless of the key locking position (the roof, the support, the elastic force accumulating means, or the sliding mechanism). Obviously, since the position can be fixed via the transmission, only the inner roof cannot be turned up unless the roof is raised.

Further, when the roof is raised, the roof can be lifted very easily by the elastic force accumulating means acting on the slide mechanism, and the internal roof can be automatically stored in the roof during the lift. it can.

Since the stored inner roof has a connection structure that is automatically fixed in position via a transmission, no mistake is made in setting or loosening a pin fixed by a person. The structure is such that it does not fall directly onto the head of a person.

That is, the above-described canopy device with the anti-theft function of the present invention has the effects of protecting the driver's seat portion from wind and rain and ultraviolet rays, and being easy to carry, cheap and easy to handle.

Also, the inner roof can prevent the tampering into the driver's seat and theft of the equipment at low cost.
