[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a suitcase with four-wheel casters.

[0002]

Conventionally, in a general four-wheel casters suitcase, with fixed castors in the rear two-wheel, also the structure freely on the front casters are attached two wheels
Was known, but in this structure,
In this holder behind the wheel holder of the universal caster
Corresponding to this when a bending force from the front acts
There was no protective function to support this power .

[0003]

[Problems to be Solved by the Invention] When two wheels of a conventional suitcase with casters as described above are to be run, normally, the suitcase is tilted rearward to float the front part, and only the two fixed caster wheels on the rear part are used. Then, it was moved by pushing it forward. However, an easier is better to pull than push in places such as slope and stairs, the front in such a case
Fixed caster at the rear by grounding only the free caster
When floating and moving it forward,
The wheel holder can not withstand bending force from the front and bends
There is a risk that problems such as
In this case, the front and back of the suitcase must be inverted.
There was a problem that it was troublesome .

In order to eliminate such troubles, the present invention has an object to allow the suitcase to be pulled forward and moved without changing the front and back of the suitcase in a place such as a slope or stairs. To do.

[0005]

In order to solve the above problems, the present invention attaches fixed casters 2 to both sides of the rear end of the bottom of the suitcase body 1, and
In a suitcase with four-wheel casters having swivel casters 3 attached on both sides of the front end of the bottom surface, the swivel casters 3 in front of the suitcase 4 are fixed to the bottom surface of the suitcase body 1, and the protector 4 is rotated horizontally. Wheel holder 5 movably attached, and wheel 6 attached to the wheel holder 5 rotatably in the front-rear direction.
The protector 4 has a structure in which a notch space 7 having an open front surface and a bottom surface is formed in the front half, and the wheel holder 5 is housed in the notch space 7 of the protector 4 and the upper surface 10 of the top 8 thereof is notched space. The top surface 11 of the slit 7 is slidably abutted, and the rear surface 12 is slidably abutted on the rear wall 13 of the cutout space 7.

EXAMPLES The examples shown in the figures will be described below.
First, in FIG. 7, reference numeral 1 denotes a suitcase body, fixed casters 2 are attached to both sides of the rear end of the bottom surface, and universal casters 3 are attached to both sides of the front end of the bottom surface. As shown in FIG. 1, the swivel caster 3 attached to the front end includes a protector 4 fixed to the bottom surface of the suitcase body 1, a wheel holder 5 rotatably attached to the protector 4, The wheel 6 is rotatably attached to the wheel holder 5. The protector 4 has a notch space 7 with its front and bottom opened in the front half, and the wheel holder 5 is housed in this notch space 7 and connected to the protector 4 by a mounting shaft 9 provided on its top 8. There is. Then, the upper surface 10 of the top portion 8 of the wheel holder 5 slidably contacts the top surface 11 of the cutout space 7, and the rear surface 12 of the wheel holder 5 also slidably contacts the rear wall 13 of the cutout space 7. It has a simple structure. The wheel 6 is attached to the wheel holder 5 by a central shaft 15 whose both ends are supported by both side walls 14 of the wheel holder 5. The center shaft 15 of the wheel 6 is slightly deviated from the mounting shaft 9 of the wheel holder 5 described above.

The present invention is a front free caster like the above.
-The protector 4 of the wheel holder 5 bearing 3 is the first half
The structure has a notch space 7 in which the front surface and the bottom surface are opened,
The wheel holder 5 is stored in the notch space 7 of the protector 4.
And slide the upper surface 10 of the top portion 8 onto the top surface 11 of the cutout space 7.
The rear surface 12 is also movably abutted and also has a notch space
7 those suitcase body 1 since the slidably abutting structure on the wall 13 even in the bending force wheel holder 5 is inclined forwardly and operation of the present invention after, then surface load acting on the wheel holder 5 It is received by the protector 4 which contacts the upper surface 12 of the top 12 and the top 12, and the wheel holder 5 itself does not receive a bending load. That is, the strength of the front free caster is increased as a whole to withstand two-wheel traveling.

[0008]

[Effect of the Invention] The present invention is as described above, and since two wheels can be driven forward by the free casters on the front, when the suitcase is to be pulled and moved from the front in a place such as a slope or stairs. In addition, unlike the conventional fixed caster that can run on two wheels only, there is no need to reverse the front and rear of the suitcase, and the suitcase body can be tilted forward and pulled in that position. This has the effect of eliminating the trouble of the past.
