Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trolley cover device capable of protecting a load placed on a trolley from sudden rain or the like.

[0002]

2. Description of the Related Art A truck is used to carry luggage, such as when it suddenly rains or when traveling short distances between buildings in rainy weather or the like. When it was not advisable for the above-mentioned luggage to get wet with paper, cloth, food, etc., it was advisable to cover the luggage with a vinyl sheet or the like on an ad-hoc basis.

[0003]

Needless to say, it is troublesome to put a vinyl sheet or the like on the luggage one by one, and it is difficult to take a quick response.
Especially for sudden rain, it often happens that the luggage gets wet because there is no suitable vinyl sheet or the like close at hand. In addition, when rain is accompanied by a strong wind, simply putting a vinyl sheet on the luggage may not be useful because the vinyl sheet will be skipped or slip off. there were.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is capable of quickly and surely protecting luggage on a trolley from sudden rain and the like, and is capable of handling the luggage easily. An object of the present invention is to provide a bogie cover device.

[0005]

According to the present invention, the following technical measures have been taken in order to achieve the above object. In other words, the truck cover device according to the present invention has a main body provided to the bogie, and a cover sheet provided so as to be able to unwind and rewind with respect to the main body. The main body is provided with a take-up device for pulling and urging the cover sheet into the main body so as to be able to hold the take-up and storage state when not in use. Is provided with a mooring fastener on its unwinding end side.

[0006] With such a configuration, by attaching the bogie cover device to the bogie usually or as needed, the cover sheet can be unwound from the main body in the event of rain or the like, and the cover can be unwound. The seat can be pulled out from the mounting position of the main body to the opposite side over the luggage placed on the trolley, and the fastener on the unwinding end side can be fixed to an appropriate position on the trolley or the like. Such a handling operation is as simple as unwinding the cover sheet from the main body, and can be performed quickly and easily. Also, since the cover sheet pulled out from the main body is pulled at one end by the winding device of the main body and held at the other end in a fixed state by the fastener, it may be blown or turned up by a little wind. There is no.

[0007] Thus, the luggage can be protected from rain and the like. Then, in the bogie cover device, when not in use, the cover sheet is wound up inside the main body,
Since it is stored, there is no hindrance when loading or unloading luggage on the trolley or running the trolley. In addition, the attachment position of the main body to the trolley, the attachment position of the fastener, and the like are not limited at all. In addition to the hooks, the fasteners may be of a magnet type or a clip type (like a clothespin). Further, the main body can be integrated into the bogie from the beginning. For example, if the diversification is arranged, there is no shortage of time.

Needless to say, the configuration of the bogie itself is not limited at all. For example, whether or not the loading platform or the handle portion can be folded, whether or not the electric traveling device is mounted, and the like do not matter at all, and the number of wheels is one. It can be adopted without any problem for all or four wheels.
It is possible to adopt a structure in which a mounting bracket is provided for the main body so as to be attachable to and detachable from the cart. In this case, it is possible to easily attach and detach the cart cover device to and from the cart.

In this case, the mounting bracket and the main body are
The relative distance between them may be fixed, but the angle can be adjusted so that the unwinding direction of the cover sheet from the main unit can be changed up and down according to the luggage shape on the loading platform. It becomes suitable. In this case, the cover sheet can always be brought into contact with the luggage without being influenced by the luggage shape (that is, the luggage loading method and the luggage amount).
This has the advantage of increasing the probability that the luggage will not get wet and making it difficult for the wind to enter the cover sheet, so that turning over can be prevented more reliably.

[0010] The mounting brackets may be provided separately (that is, a plurality) at a plurality of locations along the winding axis direction of the cover sheet in the main body. In this case, if the distance between the mounting brackets is adjustable, the distance between the mounting brackets can be optimized (in principle, as wide as possible) according to the size of the truck (the plane size of the carrier). Therefore, a stable mounting state can be obtained. It is structurally easiest for the mounting bracket to have a structure for holding the carrier of the bogie in the thickness direction. In addition, there is an advantage that general versatility can be obtained for different types of trucks as long as the thickness of the carrier is slightly different.

In addition, in order to enable mounting between trolleys having greatly different thicknesses of the pallets, the mounting bracket can be exchanged with respect to the main body portion between different types of trolleys having different clamping sizes with respect to the pallets. It is preferable to keep it.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a trolley cover device 1 according to the present invention in a state where the trolley cover device 1 is attached to a trolley 2. FIGS. 2 and 3 show examples of use of the trolley cover device 1. ing. The trolley cover device 1 includes a main body 3 provided on the trolley 2 and a cover sheet 4 provided on the main body 3 so as to be able to be unwound and wound up.

The main body 3 has a round bar shape and an elongated outer shape, and mounting brackets 5 that can be attached to and detached from the carriage 2 are provided at a plurality of locations (two locations in the figure) on the outer surface in the longitudinal direction.
Is provided. In addition, the main unit 3 is provided with a winding device 6 so as to be incorporated therein.
The take-up device 6 pulls the cover sheet 4 into the main body 3 and urges it. Therefore, when not used as the bogie cover device 1, the cover sheet 4 is wound up into the main body 3, and holds the stored state.

The cover sheet 4 is formed of a sheet material having water repellency, such as a sheet or a resin sheet knitted or woven with synthetic fiber or the like. 7 are provided. In the present embodiment, the fastener 7 has a hook shape in which a part of a ring is cut off. In addition, cover sheet 4
On the unwinding end side, a stopper rod 8 for preventing the whole of the cover sheet 4 from being wound into the main body 3 by the winding device 6 is provided so as to cover the entire sheet width. The fastener 7 is connected to the stopper rod 8.

That is, the stopper rod 8 has a function as an attachment reinforcing tool for the fastener 7 in addition to the above-described original function of preventing winding. The stopper rod 8 functions to prevent the cover sheet 4 from being wrinkled, bent, or fluttered by wind or the like when the cover sheet 4 is unwound or wound up with respect to the main body 3. Is also playing. As shown in FIG. 4, the main body 3 includes a case 15 formed by an outer cylinder 12 having both ends opened and end caps 13 and 14 for closing both ends of the outer cylinder 12. In the structure 15, the winding device 6 is assembled around the winding shaft 17 of the cover sheet 4 or the like.

The outer cylinder 12 has a slit-shaped sheet opening 18 formed at one position in the circumferential direction over the entire length in the longitudinal direction. Winding is performed. Also, on the outer peripheral surface of the outer cylinder 12, ridges 19 projecting in a bank shape over the entire length in the longitudinal direction are provided at two places separated by 90 ° to both sides in the circumferential direction around the sheet opening 18. These projections 19 are used when the mounting bracket 5 is mounted, and the operation thereof will be described later.

The take-up device 6 has the function of urging the take-up shaft 17 to rotate in one direction. The take-up shaft 17 is a cylindrical shaft with both ends open. , Spring 21
Is wound, and a spring shaft 22 equipped with is wound around. The above-described cover sheet 4 is wound around the winding shaft 17 with its one end fixed to the outer peripheral surface. The inner circumferential surface of the winding shaft 17 has two circumferentially opposite surfaces.
At a position (a position at 180 °), a key 23 that protrudes in a bank shape over the entire length in the longitudinal direction is provided.

A pair of spring stoppers 25 and 26 are attached to both ends of the spring 21 in the longitudinal direction. Although these spring stoppers 25 and 26 have different outer shapes, they are common in that they are provided with shaft holes 25a and 26a. It can be fitted. And these spring stoppers 2
5 and 26 are not shown, but are screwed or forcibly fitted.
Alternatively, they are connected to the spring 21 so as not to rotate relative to each other by an appropriate structure such as bending engagement of a spring end.

As shown in FIG. 5, one spring stopper 25
, An inner lid 27 is rotatably fitted around the rod end, and a rod end 28 is inserted into an end of the spring shaft 22 on the same side as penetrating the inner lid 27. It has become. This rod end 28
Is provided with a rotation-stop-side shaft end portion 29 that protrudes in a square shaft shape. The spring stopper 25, the spring shaft 22, and the rod end 28 are fixed in a skewered manner (that is, in a state in which they cannot rotate relative to each other) by a set screw 30 that is screwed in the radial direction. (See also FIG. 6).

The inner cover 27 is provided with an inner fitting portion 33 which can be brought into circumferential contact with the inner peripheral surface of the winding shaft 17 without rattling. Is provided with a key receiving portion 34 which can be engaged with the key 23 provided on the inner peripheral surface of the key. Further, the inner lid 27 is provided with an outer flange 35 projecting larger in diameter than the inner fitting portion 33.
The amount of fitting to can be regulated. In the other spring stopper 26 as well, an inner fitting portion 36 is provided on the inner peripheral surface of the winding shaft 17 so as to be able to make a circumferential contact without looseness. A key receiving portion 37 that can be engaged with the key 23 provided on the surface is provided.

However, this spring stopper 26 has an inner fitting portion 36.
Nothing with a larger diameter is provided, so that the spring stopper 26 is axially movable within the winding shaft 17 along its longitudinal direction. Further, the spring shaft 22 is merely inserted into the shaft hole 26a of the spring stopper 26, and the two are held in a relationship in which the two can relatively rotate and move freely. As is apparent from this, both the spring stopper 26 and the inner lid 27 are connected to the winding shaft 1.
7, and is held so as not to be able to rotate relative to (ie, to be integrally rotatable)
On the other hand, in the winding shaft 17, the spring shaft 22
The spring stopper 25 and the rod end 28 are rotatably held with both ends held by the spring stopper 26 and the inner lid 27.

When the amount of rotation of the spring shaft 22 is increased, the spring 21 is twisted between both ends of the rotating spring stopper 25 and the non-rotating spring stopper 26, and gradually this twist is generated. It is designed to increase the return rotational force (torsion effect) against the torsional force. By the way, the length of the winding shaft 17 is determined based on the sheet width of the cover sheet 4 (that is, the size of the truck).
Have the same length to accommodate the winding shaft 17. However, as shown in FIG.
7 (though it is not particularly limited, but from half the length of the winding shaft 17 to the entire length), and the spring shaft 22 is slightly longer than the spring 21 and is wound. It is formed shorter than the take-up shaft 17.

In this manner, the spring 21
The amount is reduced to the minimum necessary amount, and the cost and the weight are reduced. Even if the spring 21 and the spring shaft 22 are shortened in this manner, one end thereof is held at the center position of the winding shaft 17 by the inner lid 27, and the other end is formed by the spring stopper 26. With the winding shaft 1
7 is held at the center position. Therefore, the spring 21 and the spring shaft 22 do not cause eccentricity or fluctuation in the winding shaft 17.

As shown in FIG. 4 and FIG.
In the above, another type of inner lid 40 is fitted to the end opposite to the side where the inner lid 27 is fitted. The inner cover 40 is provided with an inner fitting portion 41 that can be circumferentially contacted with the inner circumferential surface of the winding shaft 17 without rattling. The inner fitting portion 41 has an inner circumferential surface of the winding shaft 17. Key 2 provided on the surface
3 is provided with a key receiving portion 42 that can be engaged with the key receiving portion 3. Also,
The inner lid 40 is provided with an outer flange 43 projecting larger in diameter than the inner fitting portion 41, so that the amount of fitting to the winding shaft 17 can be regulated.

Further, the inner lid 40 is provided with a rotation-side shaft end 44 protruding at the center position. The end caps 13 and 14 for the outer cylinder 12 are provided with the rotation-stop-side shaft end 2 of the rod end 28 that projects through the inner lid 27.
A bearing hole 46 (which is a square hole) and a bearing hole 47 (which is a round hole) which are respectively engaged with the rotating shaft end 9 of the inner lid 40 and the rotating shaft end 44 of the inner lid 40 are separately provided. . The end caps 13 and 14 are engaged with a sheet opening 18 provided in the outer cylinder 12, so that the outer cylinder 1
A detent piece 48 is provided so as to prevent relative rotation with respect to 2.

Therefore, the outer cylinder 12 and the end caps 13,
The spring shaft 22 is held in a state where it does not rotate at all, while the winding shaft 17 is held in a state where it rotates. The relative rotation between the spring shaft 22 and the winding shaft 17 causes the spring 21 to be twisted as described above, and thus the return rotational force (torsion effect) against the torsional force. Will be increased. Therefore, at an initial stage (when the spring shaft 22 and the winding shaft 17 are incorporated in the outer cylinder 12), an appropriate return rotational force (approximately the winding shaft 17) is applied between the spring shaft 22 and the winding shaft 17. 17 (approximately 10 rotations), the cover sheet 4 is wound around the winding shaft 17 based on the return rotational force, and the state of being housed in the main body 3 is maintained. .

Of course, if the cover sheet 4 is unwound from this state, the above-mentioned return rotational force is further increased, so that the cover sheet 4 is continuously subjected to the drawing bias toward the inside of the main body 3. When the unwinding force is released, the cover sheet 4 is always wound up and stored in the main body 3. As shown in FIG.
The mounting bracket 5 has a substantially ring-shaped holder 53 for holding the main body 3, and a clamp 54 provided to extend radially outward from the holder 53.

The clamp portion 54 includes a pair of clamp pieces 5
5, 56, one or both of which are elastically biased toward each other. Therefore,
With this urging force, the carrier 52 of the carriage 2 can be sandwiched in the thickness direction. In the illustrated example, each clamp piece 5
At the roots of 5, 56, a curved portion 57 for enhancing elastic biasing force is formed. Holder part 5
3 is a sheet opening 18 with respect to the main body 3 (outer cylinder 12).
Except for, it has a shape that surrounds it more than half a lap. And, two hook portions 59 which can be engaged with the two ridges 19 provided on the outer cylinder 12,
The backup surface 6 provided at an intermediate position in these circumferential directions
At a total of three locations, namely 0, the outer cylinder 12 can be brought into contact with the outer peripheral surface.

In the holder portion 53, a large-diameter portion 61 is provided between the hook portions 59 and the backup surface 60 in the circumferential direction so as to allow the ridge 19 to move freely in a predetermined angle range. I have. And these large diameter parts 6
1 is symmetrically arranged around the center of the holder 53. Therefore, this mounting bracket 5 (holder 5
In contrast to 3), the main body 3 has a ridge 1 inside the large-diameter portion 61.
9 is rotatable in an angular range θ in which it can move circumferentially.
Therefore, when the main body 3 is mounted on the trolley 2 using the mounting bracket 5, the main body 3 moves the direction in which the sheet opening 18 is oriented, that is, the unwinding direction of the cover sheet 4 up and down. The angle can be adjusted by changing the swing. Thereby, the cover sheet 4 can be unwound at an optimum angle each time according to the luggage shape on the luggage carrier 52.

As described above, this mounting bracket 5
Are provided separately at a plurality of locations in the longitudinal direction of the main body 3, that is, at a plurality of locations along the winding axis direction of the cover sheet 4. Each of the mounting brackets 5 is rotatable around the main body 3 as described above, and is also axially movable in the longitudinal direction with respect to the main body 3. Can also be adjusted arbitrarily. Furthermore, the mounting bracket 5 can be freely fitted and removed along the longitudinal direction of the main body 3 as long as the hook portions 59 and the backup surface 60 do not interfere with the ridges 19 and the sheet opening 18.

Therefore, as shown in FIG.
3 in which the clamp pieces 55 and 56 are different from each other in the clamp portion 54,
If a plurality of types are prepared, the carrier 5
By appropriately selecting the one having the optimum holding size with respect to 2, it becomes possible to cope with various bogies having different thicknesses. As described above, in the bogie cover device 1 according to the present invention, the mounting bracket 5 is connected to the front end of the bogie 52, for example, as shown in FIG. The main body 3 is attached.

Then, when the dolly 2 is used and a rain or the like is encountered, the fastener 7 or the stopper rod 8
To unwind the cover sheet 4. And
As shown in FIG. 2 or FIG. 3, the cover sheet 4 is pulled out from the mounting position of the main body 3 to the opposite side over the luggage placed on the truck 2, and the fastener 7 is moved to, for example, the handle 65 of the truck 2. Or the rear end of the carrier 52 or the back plate 66 or the like. In some cases, the fastener 7 may be hooked directly to the appropriate place of the load.

Therefore, the luggage can be protected from rain and the like. As is clear from the comparison between FIG. 2 and FIG. 3, the main unit 3 swings the direction in which the sheet opening 18 is directed, that is, the unwinding direction of the cover sheet 4 in accordance with the luggage shape. The cover sheet 4
Is in perfect contact with the luggage in each case. Therefore, the probability that the luggage does not get wet increases. Further, since it is difficult for the wind to enter the cover sheet 4, the turning up of the cover sheet 4 can be more reliably prevented. In addition, it also leads to the advantage that the unwinding and winding of the cover sheet 4 with respect to the main body 3 becomes smooth.

The trolley cover device 1 may be attached to the side of the carrier 52 as shown by a two-dot chain line in FIG. Further, as shown by a solid line in FIG. 10, the truck 65 may be attached to the handle 65 at a predetermined height position, or in this case, a structure capable of adjusting the height may be added. In this case, it is necessary to replace the structure of the mounting bracket 5 with a structure applicable to the handle 65, but such a structural change is within a range that can be appropriately selected from conventionally known various structures. .

The present invention is not limited to the above embodiment, and various modifications and changes can be made to the detailed structure. For example, the mounting bracket 5 may be fixed to the main body 3. Further, they may be provided integrally. The mounting bracket 5 may be configured to switch between holding and releasing the carriage 2 with respect to the carrier 52 by operating a screw structure. The outer shape of the main body portion 3 can be a square bar shape or the like in addition to the round bar shape, and can be shortened in length to apply a plurality to a single carrier 52. .

It is also possible to provide a plurality of fasteners 7 on the cover sheet 4.

[0037]

As is apparent from the above description, in the bogie cover device according to the present invention, when sudden rain or the like is encountered, the cover sheet is unwound from the main body while the cover sheet is unwound. It can be pulled out from the mounting position of the main body to the opposite side over the luggage placed on the trolley, and the fastener on the unwinding end side can be fixed to an appropriate position on the trolley or the like. Therefore, the luggage on the trolley can be quickly and reliably protected from rain and the like, and handling thereof is also very easy.

When not in use, since the cover sheet is wound into the main body by the winding device, there is no hindrance when loading / unloading the luggage on the carriage or running the carriage. When a mounting bracket is provided on the main body to simplify attachment and detachment to and from the trolley, adopting a structure that allows the unwinding direction of the cover sheet to be changed up and down increases the probability that the luggage will not get wet, The flip-up can be prevented more reliably.

If a plurality of mounting brackets are provided along the direction of the winding axis of the cover sheet, the mounting state can be stabilized. In this case, if the distance between the mounting brackets can be adjusted, it is possible to cope with various trucks having different carrier widths. In addition, by making the mounting bracket a holding structure for the carrier of the bogie or being replaceable with mounting brackets having different holding sizes, it becomes possible to cope with various bogies having different thicknesses.
