And the sliding section 20. The sliding portion 20 is composed of inclined portions 21 and 21 provided on both front and rear sides and a horizontal portion 22 in the middle thereof, and is provided on both sides of the lower surface of the luggage carrier 10. The inclined portion 21 may be formed by an outwardly convex curved portion formed by curving the inclined straight portion. Each of the sliding parts 20 has the same shape as that of the sliding part frame body 20a.
It has a structure in which the sheets are overlapped with each other with a spacer member 24 interposed so as to hold a predetermined narrow interval, and continuous groove portions 25 are formed on the outer peripheral surface of the sliding portion 20 (see FIG. 5). ). The groove portion 25 engages with a protrusion that is arranged on the inner peripheral surface of the belt as a rotating member, which will be described later, so that the rotation of the belt can be guided.

A belt 42 made of an endless cloth is stretched around the respective sliding portions 20 on both sides thereof. The belt 42 serves as a rotating member. Further, as a matter of course, the sliding member 23 is provided on the lower surface of the sliding portion 20 as in the above-described embodiments. A non-slip member 45 is added to the entire outer peripheral surface of the belt 42. As the anti-slip member 45, rubber or the like is added so as to be scattered on the outer peripheral surface of the belt 42. Further, a large number of protrusions 43 are formed on the inner peripheral surface of the belt 42.
Are arranged in a line in the central portion of the belt 42 in the rotating direction and in a line at a constant interval over the entire inner peripheral surface thereof. This protrusion 4

They may be arranged in rows. In this case, it can be carried out without providing the groove portion 25 on the outer peripheral surface of the sliding portion 20.

From the above, when carrying luggage on the floor or climbing stairs using this carrying device,
The load to be transported is placed on the loading platform 10, and the transport tool is pushed manually. At that time, between the lower surface (outer peripheral surface) of the sliding part 20 of the transport tool and the inner peripheral surface of the belt 42. Since the frictional resistance of the two is small, they slip and the other belt 42
Since the non-slip member 45 is added to the outer peripheral surface of the
The frictional resistance between the outer peripheral surface of the belt 42 and the surface of the floor, for example, and the corners of the steps of the stairs increases, and no slippage occurs between them, which causes the belt 42 to rotate around the sliding portion 20. As a result, the sliding part 20 of the transporting tool moves in the pushed direction.

That is, in FIG. 4, when the outer peripheral surface of the sliding portion 20 and the inner peripheral surface of the belt 42 slide, the outer peripheral surface of the belt 42 slides by being pushed in the direction of arrow P by human power or the like. Since there is not, the sliding section 2 inside the belt 42
0 shifts in the forward direction F, and at the same time, the belt 42 rotates in the direction of arrow R. In this way, the gliding carrier according to the present invention can move the floor surface or the like in the forward direction or gliding up and down the stairs. The lateral widths of the sliding portion 20 and the belt 42 can be freely set, and the number of them may be three or more on the lower surface of the luggage carrier 10 as well as on both sides of the luggage carrier 10 as described above. This is the same as that described in the embodiment of FIG. 3, and the loading platform 10 may be located between the sliding parts 20 on both sides. Although the inclined portions 21 of the sliding portion 20 are provided on both the front and rear sides, the inclined portions 21 may be provided on only one side.

FIG. 6 is a side view showing another embodiment of the present invention. Only the sliding portion 20 is shown, and the cargo bed portion and the supporting portion are the same as those in the above-mentioned embodiment. , Omitted. The sliding portion 20 includes metal rings 35, 36 provided at both ends and the rings 35, 36.
It is composed of an inclined part 21 and a horizontal part 22 that connect 36, and the inclined part 21 and the horizontal part 22 are also made of metal and welded to each other. Therefore, the sliding portion 20 is formed of the inclined portion 21 and the curved portions (rings 35, 36) continuous on both sides of the horizontal portion 22.

Similar to the embodiment shown in FIG. 4, continuous grooves are also formed on the outer peripheral surface of the sliding portion 20. The structure of the belt 42 made of cloth is also the same as that of the embodiment shown in FIG. 4, and an anti-slip member is added to the entire outer peripheral surface thereof, and a large number of protrusions 43 are formed on the inner peripheral surface thereof.
The belt 42 is arranged in a line at the center of the rotation direction of the belt 42, and is arranged at regular intervals over the entire inner peripheral surface thereof. In this embodiment, the inclination angle of the inclined portion 21 with respect to the horizontal plane is small. Therefore, in order to climb onto the stairs from a horizontal floor surface or the like, one end of the sliding portion 20 is lifted to raise the first portion of the stairs. It is necessary to mount the inclined portion 21 or the horizontal portion 22 of the sliding portion 20 on the corner portion of the step.

FIG. 7 is a side view showing still another embodiment of the present invention, in which only the sliding portion 20 is shown, and the luggage carrier portion and the supporting portion are shown in the same manner as the above embodiment. Since it is similar, it is omitted. FIG. 8 is a sectional view taken along line TT of FIG. In this embodiment, the sliding portion 20 and the rotating member are all made of metal, and the sliding portion 20 includes two upper and lower horizontal portions 22 and 22 and substantially semicircular curved portions 2 at both ends.
It is composed of a frame body formed by 7 and 27. The rotating member that is bridged over the outer circumference of the sliding portion 20 is a channel member 46 of a constant length, which is made of metal and has a U-shaped cross section as a dividing member.
Are connected endlessly in an annular shape, and are assembled so that the sliding portion 20 fits inside the channel member 46. The respective channel members 46 are axially attached to each other by pins 47 at both ends thereof, and a rotary body 48 is attached to the shaft portion of the pins 47.

Therefore, the rotating body 48 smoothly rolls on the outer peripheral surface of the sliding section 20, so that the rotating member, which is the connecting body of the channel members 46, rotates around the sliding section 20. The gliding unit 20 can gliding. In this gliding run, it is possible to easily glide up and down the stairs as well as the horizontal floor surface. However, since there is no slope on the sliding section 20, when climbing up the stairs from a horizontal floor surface, etc., it is necessary to climb the first corner of the stairs even if it is pushed. Therefore, the horizontal portion 22 is lifted so as to be placed on the corner portion of the first stage, so that the subsequent gliding climbing can be easily performed.

The sliding portion 20 and the rotating member may be made of other materials such as hard synthetic resin instead of metal. In this embodiment, since the rotating body 48 is attached to the shaft portion of the pin 47, the sliding portion 20
There is no need to attach a sliding member to the outer peripheral surface of the. Further, the protruding portion 43 required in the above-described embodiment is not required on the inner peripheral surface of the rotating member. In addition, the rotating body 48 is the pin 4
Although it is attached to No. 7, it is also possible to provide an appropriate shaft at a site other than the place of the pin 47 for axially attaching the channel material 46 to each other, and to attach the rotating body to this shaft. Pin 4
It is also possible to carry out without attaching the rotating body 48 by attaching 7 itself so as to rotate.

Further, even when the pins 47 themselves do not rotate, it is possible to carry out without attaching the rotating body 48. In that case, the sliding portion 20 is directly mounted on the shaft portion of each pin 47. It is possible to slide and run by sliding the outer peripheral surface of the. A material other than the channel material 46 may be used as the dividing member. For example, two strip-shaped members are arranged in parallel, a split member is prepared by connecting pins at both ends thereof, and the rotating members are formed by interconnecting these at each pin portion. You can also do it. That is, the channel member 46 may not have a bottom surface. The other dividing member may be in the form of a chain. In the case of this dividing member, it is necessary that both side surface portions of the dividing member are located outside both side surfaces of the sliding portion 20, so that the rotating member does not come off from the sliding portion 20.

Although the embodiment of the sliding carrier according to the present invention has been described above, the embodiment can be changed as follows. First, the sliding portion 20 has an inclined portion 21 or a curved portion and a horizontal portion 22 continuous to the inclined portion 21 or the curved portion, and the lower surface (outer peripheral surface) of the inclined portion 21 or the curved portion and the horizontal portion 22 is a sliding surface having low frictional resistance. Be formed, or
In addition to this, it suffices that a rotating member such as the belt 42 is spanned, and the structure, shape, and the like can be designed completely freely. The inclined portion 21 or the curved portion may also be provided on one side of the horizontal portion or on both sides thereof. The width thereof is also free, and the number of the sliding parts 20 may be determined as needed. A combination of both the inclined portion and the curved portion may be connected to one end or both ends of the horizontal portion 22.

The angle and length of the inclined portion 21 and the length of the horizontal portion 22 can be appropriately set as necessary.
In addition, it is preferable that the horizontal portion 22 has a length such that the horizontal portion 22 can be bridged over the corners of three steps of a general staircase. The material of the sliding member 23 added to the outer peripheral surface of the sliding portion 20 can be freely selected, and any material can be used as long as it has a low frictional resistance. The sliding member 23 may be formed separately from the sliding section 20 and bonded later, or may be manufactured integrally with the sliding section 20.

The belt 42 is not necessarily made of cloth, and belts made of other materials can be used. In that case, the frictional resistance of the inner surface is low, and the outer surface of the frictional resistance may be anti-slip. The anti-slip member may be applied, or a large number of non-slip projections may be provided to provide friction resistance. It may be formed as a large surface. The groove portion 25 provided on the outer peripheral surface of the sliding portion 20 that engages with the protruding portion 43 provided on the inner peripheral surface of the belt 42 is also formed by overlapping the sliding portion frame body 20a in the above-described embodiment. Not only in the above, but also in the groove portion 25 over the entire outer peripheral surface of the sliding portion 20.
As long as it is formed, any other manufacturing method may be adopted.

Further, the groove portion 25 provided on the outer peripheral surface of the sliding portion 20 is not always indispensable, and the groove portion 25 can be implemented without providing it. For example, the projecting portions may be arranged in two rows in the rotating direction over the entire inner peripheral surface of the belt 42 so as to sandwich the outer peripheral surface of the sliding portion 20 in the middle. In this case, it is necessary to provide a horizontal frame also above the sliding portion 20 so that the belt 42 is stretched over the entire outer peripheral portion of the sliding portion 20. By doing so, the protrusion is always located inside and outside the outer periphery of the sliding part, and it is possible to prevent the protrusion from being caught by the sliding part. The protruding portions 43 arranged in a row do not have to be arranged in a dot shape, and may be a linear piece having a certain length. Lastly, the position of the luggage carrier 10 can be freely arranged. However, in consideration of the size of the transported object, the luggage carrier 10 is located above the gliding unit 20, that is, the gliding unit 20 is the luggage carrier 10. Most preferably, it is located on the underside of.

EFFECTS OF THE INVENTION The present invention having the above-mentioned various forms has the following effects. In the first aspect of the present invention, not only flat floors and roads, but also stairs can be pushed and slid up in the same state. Therefore, it is possible to easily carry the luggage upstairs by using the stairs even if the elevator or the like is not installed in the building. Especially, it is very convenient to carry furniture upstairs in the house of a general household such as a two-story building or a three-story building. It can be easily carried up.

According to the second aspect of the present invention, the rotation of the rotating member hung on the sliding portion makes the carrier more slippery, so that even a heavier baggage can have a good staircase. It is possible to make a gliding climb and carry it up. In the third aspect of the present invention, the presence of the protruding portion provided on the inner peripheral surface of the belt, which is the rotating member, serves as a guide for the belt and prevents the belt from coming off the sliding portion. Can be done. Further, since the belt is made of cloth, the manufacturing cost can be reduced.

According to the fourth aspect of the present invention, the sliding member slides smoothly on the shaft portion of the shaft attachment portion that connects the rotating members to each other, so that the rotating member moves around the sliding portion extremely smoothly. This makes it possible to perform a very smooth gliding run even on stairs as well as on a flat floor where the carrier is flat. Further, since both side surface portions of the rotating member are located outside the both side surface portions of the sliding portion, the rotating member will not come off from the sliding portion. As described above, the invention of the present application exerts a great effect.
