DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a service cart. That is, the present invention relates to a service cart used for in-flight service for passengers in an aircraft, for example.

[0002]

2. Description of the Related Art Such a service cart has a box shape, is provided with a door and a caster, and stores articles therein. In addition, when used for in-flight services, etc., articles are often placed on the top plate, for example, a box-shaped container storing articles is placed on the top plate and circulates inside the aircraft, It is provided for services such as browsing and sales of documents. By the way, the service cart used for in-flight services, etc., has its outer dimensions regulated and the dimensions and area of the top plate fixed. Insufficient, the number and size of articles to be placed and their box-shaped containers were very limited, which was inconvenient and service efficiency was poor. Conventionally, as shown in a schematic perspective view of FIG. 6, a separate table 1 is used in such a case. (1) In the figure, the separate table 1 is mounted on the top plate 2 and attached. Example,
(2) The figure shows an example in which the separate table 1 is mounted so as to be substantially flush with the top plate 2. That is, by installing a separate table 1 separate from such a service cart as needed, the area on the service cart can be increased,
Thus, the number of articles that can be placed and the number of the box-shaped containers H and the like are increased so that a larger one can be placed. In addition, 3 in the figure is a caster.

[0003]

The following problems have been pointed out in such a conventional example. First, the separate table 1 can be attached to the service cart as needed, and when not in use, it is detached from the service cart and stored separately. It was pointed out that it was necessary to secure a storage place for the car. In particular, in the case of a service cart used for in-flight service, since the outer dimensions of the service cart are strictly controlled by the inner dimensions of the in-flight cart storage section, that is, the galley, such attachment and detachment of the separate table 1 is indispensable. In addition, since these operations are performed in a narrow machine, it is very troublesome and troublesome, and it is not easy to secure a storage space dedicated to the separate table 1 in the narrow machine. Second, separate table 1 which is originally a separate body
Is attached to the service cart and used, so the dimensional accuracy is poor and it is apt to be out of order, and the separate table 1 is apt to come off or rattle, so that the articles and their box-shaped containers placed on the separate table 1 are used. There was also a danger of accidents such as H swinging and falling. Especially in the case of a service cart used for in-flight services, the in-flight is unstable,
The danger of the occurrence of these accidents was great and was a problem.

The present invention has been made in view of such circumstances, and has been made in order to solve the above-mentioned problems of the conventional example. In the first aspect, a slide portion and a table portion which take a predetermined storage position and a development position are set. By providing the developing section having the following configuration, and in claim 2, further by providing the auxiliary developing section which takes a predetermined storage position and the developing position, firstly, the mounting of the developing section and the auxiliary developing section is performed. It is not necessary to remove it, it is simple, easy and labor-saving, and it does not need a dedicated storage place. Secondly, it can be prevented from being detached and rattled.
It is another object of the present invention to propose a service cart in which an area for mounting articles, its box-shaped container, and the like is expanded.

[0005]

The technical means of the present invention for achieving this object is as follows. First, claim 1
Is as follows. That is, the service cart has a box shape, is provided with a door and a caster, and stores therein articles for various services. And near the top plate,
A developing section having a flat slide section and a table section is provided. The slide portion is horizontally movably assembled to a storage position built in the cart main body below the top plate and a deployed position where the tip side is pulled out of the cart main body from below the top plate. The table has a base end hinged to the distal end of the slide portion and is horizontally movable with the slide portion. The table portion is located below the slide portion that takes the storage position in the cart body below the top plate. It is rotatable between a storage position built in the side and a development position held above the slide portion taking the development position outside the cart body and substantially flush with the top plate.

Next, claim 2 is as follows. That is, this service cart is further provided with an auxiliary deploying portion in addition to the configuration of the above-described claim 1, the auxiliary deploying portion has a long plate shape, and the deploying portion is not provided on the cart body. Hinged to the edge of the top plate on the side, and can swing between a storage position along the cart body and a deployment position that projects horizontally from the cart body and is substantially flush with the top plate. I have.

[0007]

The present invention comprises the above-mentioned means, and operates as follows. That is, when the service cart is used for services such as browsing and selling by placing articles and their storage containers, etc., the slide portion of the deploying section is moved from the storing position in the cart body to the deploying position outside the cart body. At the same time, the table section of the developing section is rotated from the storage position in the cart body to the developing position on the slide section outside the cart body. In addition, in the service cart according to the second aspect, the auxiliary deploying portion swings from the storage position along the cart body to the deploying position protruding from the cart body. So the first
In addition, the slide portion, the table portion, and the auxiliary deploying portion of the deploying portion are moved, rotated, and swung to the storage position when not in use and to the deployment position when in use. As described above, since the deploying section and the auxiliary deploying section are provided integrally with the cart main body, not separately, the deploying and storing operation is easy and easy, and a dedicated storage place is not required. Secondly, since the deploying portion and the auxiliary deploying portion are integrated with the cart body, the dimensional accuracy is good and the deviation is hard to occur, and the detachment and rattling are prevented. Third, and in addition to the top plate of the cart main body, the area on which articles, their box-shaped containers, and the like are placed is increased by the amount of the table portion and the auxiliary deploying portion of the deploying portion that takes the deploying position.

It functions to prevent slipping and falling from the base edge.

Next, as shown in FIGS. 1, 2, and 4, the auxiliary deploying portion 5 is formed in an elongated plate shape, and the cart body S is provided on the side where the deploying portion 4 and the opening 10 are not provided. The edge of the plate 2 is hinged. In other words, the left and right edges of the top plate 2 that are not on the opening 10 side of the cart body S, and the left and right frame frames 7 that hold the top plate 2 in the illustrated example, are each provided with two double hinge portions 14 by the auxiliary deploying portion 5. The auxiliary deploying portion 5 is formed in an elongated plate shape having a narrow width between the proximal end and the distal end and substantially matching the depth of the top plate 2. ing.

As shown in FIG. 4, the double hinge portion 14 has hinges 15 at both ends, each of which can be turned 90 degrees about a horizontal axis. The base end of the auxiliary deploying portion 5 is attached to the front end of the double hinge portion 14 so as to be rotatable by 90 degrees by the hinge 15, and the base end of the double hinge portion 14 is a frame on the left and right edges of the top plate 2. It is attached to the frame 7 by a hinge 15 so as to be rotatable by 90 degrees.
The auxiliary deploying portion 5 is rotatable by 180 degrees with respect to the frame 7 of the top plate 2 via the double hinge portion 14. Accordingly, the auxiliary developing unit 5 is configured to store the storage position B placed along the edge of the top plate 2 of the cart body S and the top plate 2 of the cart body S.
, And can swing to a deployment position A which is substantially flush with the top plate 2. In addition, a rising portion 13 similar to the above-described table portion 9 of the developing unit 5 is also formed at the tip of the auxiliary developing unit 5.

The present invention is configured as described above. Then, it becomes as follows. In the service cart, articles are stored inside the cart body S and provided for various services, and the articles and the box-shaped container H (FIG. 3, FIG.
4 and 6) and the like, and travel around the cabin or the like to provide services such as browsing and selling the articles.
In such a case, in this service cart, a slide mechanism (not shown) is used to move the slide portion 8 of the deploying portion 4 from the storage position B in the cart body S to the deploying position A outside the cart body S. The table unit 9 of the developing unit 4 is moved from the storage position B below the sliding unit 8 in the cart body S to the developing position A on the sliding unit 8 which takes the developing position A outside the cart body S. Then, it is rotated 360 degrees by the double hinge portion 11 to make it substantially flush with the top plate 2 (see FIGS. 1, 3 and 5). Further, in this service cart, in addition to these, the auxiliary deploying portion 5 is moved by the double hinge portion 14 from the storage position B on the top plate 2 of the cart body S to the deploying position A horizontally protruding from the cart body S. The front and back are swung upside down to be substantially flush with the top plate 2 (see FIGS. 1 and 4). Therefore, in this service cart, the following first, second, and third cases are performed.

First, when the slide portion 8 and the table portion 9 of the developing portion 4 are not used, they are moved and rotated to a storage position B which is built in the cart body S and does not obstruct the slide portion 8 and the table portion 9.
In use, the slide portion 8 is moved horizontally to the unfolded position A.
The table section 9 is moved and rotated to the deployed position A, which is substantially flush with the top plate 2 outside the cart body S, while being pulled out. In addition, the auxiliary deploying portion 5 is also swung to the unobstructed storage position B along the cart body S when used, and is deployed horizontally from the cart body S and substantially flush with the top plate 2 when used. Swinged to position A. As described above, since the slide portion 8, the table portion 9 and the auxiliary deploying portion 5 of the deploying portion 4 are provided not integrally with the cart body S but integrally with the cart main body S, the deploying and storing operation is simple and easy. As in the conventional example of this type shown in FIG. 6, it is not necessary to perform troublesome mounting and dismounting, and it is not necessary to provide a dedicated storage place when not in use.

Second, the slide portion 8, the table portion 9 and the auxiliary deploying portion 5 of the deploying portion 4 are not provided separately from the cart body S but are provided integrally. Therefore,
Since the dimensional accuracy between them and the cart body S is good and the deviation is less likely to occur, it is possible to prevent the disengagement and rattling at the deployed position A in particular.

Third, in this way, in this service cart, in addition to the top plate 2 of the cart main body S, the development position A
The area on which the article, its box-shaped container H and the like are placed is enlarged by the amount of the table section 9 and the auxiliary developing section 5 of the developing section 4 which takes the above.

First, in the service cart of the illustrated embodiment, the developing unit 4 is provided at one end of the top plate 2 of the cart body S, and the auxiliary developing unit 5 is provided at the other opposing left and right edges. However, the present invention is, of course, not limited to such embodiments, and various other embodiments are possible. For example, an example in which only the developing unit 4 is provided and the auxiliary developing unit 5 is not provided is also possible.
In this case, the number of the developing unit 4 may be singular or plural,
Further, even in the example in which the auxiliary developing section 5 is provided together with the expanding section 4, the number of the expanding section 4 and the auxiliary expanding section 5 can be variously combined as a single number or a plurality. In this manner, it is possible to appropriately increase or decrease the area on which the article and the box-shaped container H are placed.

Secondly, in the service cart of the illustrated embodiment, the auxiliary deploying section 5 has a horizontal storage position placed on the top plate 2 of the cart body S as shown in FIGS. Although the position B is taken, the present invention is of course not limited to this. In other words, the auxiliary deploying portion 5 is moved to the storage position B in the vertical posture along the side plate 6 side, not the top plate 2 side of the cart body S.
It is also possible to oscillate. When the storage position B is set along the side plate 6 as described above, a normal single hinge can be used as the hinge for connecting the auxiliary developing portion 5 with the hinge, instead of using the double hinge portion 14 as in the illustrated embodiment. There is an advantage that it is excellent in cost.

[0022]

As described above, according to the first aspect of the present invention, the service cart according to the present invention is provided with a deploying portion provided with a slide portion which takes a predetermined storage position and a deploying position, and a table portion. According to the second aspect of the present invention, the following effects are exhibited by providing the auxiliary deploying portion that takes the predetermined storage position and the deploying position.

First, since the deploying section and the auxiliary deploying section are provided integrally with the cart body instead of being separate from the cart body, troublesome mounting and dismounting are not required, labor is saved, and the deploying and storing operation is easy. It is easy and does not require a dedicated storage space. In particular, in the case of a service cart used for in-flight service, the outer dimensions are strictly regulated by the inner dimensions of the cart storage section, that is, the galley, and the inside of the aircraft is narrow, so that the effect of simplification is remarkable. In addition, there is a great effect that a dedicated storage place is not required.

Second, since the developing section and the auxiliary developing section are provided not integrally with the cart main body but as an integral part, detachment and rattling are prevented. Therefore, accidents in which the loaded articles and their box-shaped containers are rocked or dropped are also avoided. Particularly, in the case of service carts used for in-flight services, these accidents are prevented because the interior of the aircraft is unstable. The effect is great.

Thirdly, in this service cart, the area on which articles and their box-shaped containers and the like are placed is enlarged, so that the number of articles and their box-shaped containers and the like which can be placed is increased.
Larger items can be loaded, which is convenient and service efficiency is improved. As described above, the effects exhibited by the present invention are remarkably large, for example, the problems existing in this type of conventional example are eliminated.
