Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wheel member premised on use in a storage case and a storage case using the same.
[0002]
[Prior art]
A plastic storage case for storing clothing and daily necessities is known. This type of storage case is generally placed using storage spaces such as closets and closets, gaps between furniture, and dead spaces such as verandas, and is used by being stacked in multiple stages. There were also many.
[0003]
For this reason, unlike interior furniture that is always installed, there are many opportunities to move and displace items once placed as necessary, and wheels have been conventionally installed at the bottom to facilitate movement. It was broken. In this case, in addition to those using casters as wheels, those in which wheels are incorporated in the storage case itself (for example, JP-A-8-64657) have been known.
[0004]
[Problems to be solved by the invention]
The former of the above prior arts has a problem that the manufacturing cost increases due to the structure of the caster in which the wheel is rotatably held on the caster main body having a rotation shaft for the storage case. Furthermore, as a result of the height of the rotating shaft being increased, the height of the storage case itself is increased accordingly, and this problem cannot be ignored when considering placing in a limited space. In the latter case, there is a problem that the operation of removing the wheel is troublesome for a consumer who does not want to move by the wheel, and this is a problem common to the former. Furthermore, the above prior art has only an alternative idea of whether or not to add a rolling function by wheels to the storage case, and the wheel and its mounting mechanism are used for other purposes. There was no idea.
[0005]
[Means for Solving the Problems]
The present invention was created in view of the above-mentioned problems of the prior art, and provides a wheel member that not only solves the problems of the prior art but also allows new functions to be added thereto. The purpose is to do.
[0006]
[Means for Solving the Problems]
That is, the wheel member of the present invention is provided with an insertion recess for inserting the wheel member having the following configuration (a) in the bottom or the bottom and the ceiling, and the shape of the insertion recess can be inserted in two different directions. It is characterized by its shape.
(B) a hollow wheel case having at least one of upper and lower ends as an opening and a wheel rotatably provided in the wheel case so that the rolling surface is exposed to the outside from the opening. A wheel member characterized in that a locking projection protruding outward is provided on the middle circumferential side in the vertical direction, and the circumferential shape of the upper and lower wheel cases of the engagement projection is the same .
[0007]
DETAILED DESCRIPTION OF THE INVENTION
1 to 5 are views showing an embodiment of the wheel member of the present invention. The wheel member of the present invention includes a wheel 6 and a wheel case 2 in which the wheel 6 is accommodated. The wheel case 2 is formed in a hollow shape with one opening 3 made of plastic, and here, the peripheral side shape is formed in a rectangular parallelepiped. And the latching protrusion 4 which protrudes outward is provided in the middle peripheral side of the up-down direction of the wheel case 2, and the latching protrusion is comprised as a flange-shaped protrusion which continues over the outer periphery of a wheel case here. In this case, it is essential that the peripheral side portions 2A and 2B of the upper and lower wheel cases of the engaging projections have the same shape, which is a characteristic portion of the present invention.
[0008]
Next, the wheel 6 is configured such that a rotating shaft 7 integrally formed of plastic protrudes on both sides, and has a circular shape with lower ends provided on both side walls of the opening 3 of the wheel case 2 as open sides. When the rotary shaft 7 is fitted into the notched grooves 5 and 5, the rolling surface is provided rotatably in the wheel case with the rolling surface exposed to the outside through the opening. In this case, the diameter of the circle of the notch grooves 5 and 5 of the wheel case 2 is configured to be larger than the diameter of the rotating shaft 7 of the wheel 6, and the width of the notch groove on the open side is smaller than the diameter of the rotating shaft. Composed. As a result, if the rotary shaft 7 of the wheel 6 is press-fitted into the cutout groove 5 of the wheel case 2 from the open side, the rotary shaft passes through the open side and is loosely fitted and held in the cutout groove due to deformation of both. It will be.
[0009]
In the above embodiment, the wheel case 2 may be provided with openings at the top and bottom, and the peripheral shape is not limited to a rectangle, but may be a square.
[0010]
6 to 1 1 is a diagram showing a reference example of the housing case using the wheel member of the present invention. Here, it is assumed that the storage case is a plastic storage case that can be stacked in a multistage manner (for convenience, the lower storage case is denoted by 11A and the upper storage case is denoted by 11B). Insertion recesses 11 </ b> A (11 </ b> B) for inserting the wheel member 1 are provided at four locations on the bottoms of these storage cases (see FIG. 11). Further, four insertion recesses 13A for inserting the wheel member 1 are provided in the ceiling portion of the lower storage case. In these cases, the insertion recess 11A (13A, 11B) is configured in a shape that matches the circumferential shape of the wheel case 2 of the wheel member, but in the embodiment described above, the insertion recess 11A (13A, 11B) is formed in the circular notch groove of the wheel case. Since the end of the rotary shaft 7 of the loosely fitted and held wheel protrudes from the wheel case, convex relief portions 12A and 12A for escaping this portion are provided on both sides of the insertion concave portion (see FIG. 10). In this embodiment, the insertion recess 11A (11B) provided at the bottom of the housing case is configured to be slightly smaller than the outer shape of the wheel case 2 of the wheel member in order to prevent the wheel member 1 from falling off. The wheel case is configured to be fitted and held. On the other hand, the insertion recess 13A provided in the ceiling portion of the storage case does not need to be as described above, and conversely, the outer shape of the wheel case 2 of the wheel member can be easily lifted so that the upper storage case stacked can be easily lifted. It is configured to be slightly larger and loosely fitted.
[0011]
When the wheel member 1 is used, it is inserted into the insertion recess 11A (13A, 11B) of the storage case. As shown in FIG. 7, in this case, the circumferential locking projection 4 abuts the circumferential side of the insertion recess. Therefore, it becomes a stopper for restricting further insertion.
[0012]
The wheel member can be used as follows for the storage case having the above-described configuration.
(1) By inserting the 2A side of the wheel case 1 of the wheel member 1 into the insertion recess 11A at the bottom of the storage case 10A located at the lower stage, the rolling surface of the wheel 6 is positioned below the storage case, It becomes a wheel for movement (refer to Drawing 6 and Drawing 7).
(2) The wheel member 1 is turned upside down, and the non-wheel side of the wheel member is positioned below the housing case by inserting the 2B side of the wheel case into the insertion recess 11A at the bottom of the housing case 10A located at the lower stage. It becomes an adjuster for placing the storage case (see FIG. 8).
(3) Insert the wheel case 1B side of the wheel member 1 into the insertion recess 11B at the bottom of the housing case 10B located at the upper stage, and insert the recess at the ceiling of the housing case 10A located at the lower side of the wheel case 2A. By inserting it into 13A, it becomes a joint for connecting the upper and lower housing cases (see FIGS. 6 and 9). In this case, the wheel member may be upside down.
[0013]
12 to 14 are views showing an embodiment of the storage case of the present invention. In this embodiment, the wheel member 1 can be inserted in two different directions by forming the insertion recess 20A provided at the bottom into a cross shape. That is, if the wheel case 2 is inserted so that the rotation direction of the wheel of the wheel member matches the front-rear direction of the storage case 10A as shown in FIG. 13, the storage case can move in the front-rear direction, as shown in FIG. If the wheel case 2 is inserted so that the rotational direction of the wheel of the wheel member matches the left-right direction of the housing case 10A, the housing case can be moved in the left-right direction.
[0014]
【The invention's effect】
The present invention configured as described above has the following specific effects.
(1) Since the wheel can be attached to the storage case simply by inserting the wheel member incorporating the wheel into the insertion recess of the storage case, the customer can attach and detach the wheel to the storage case with a single touch if necessary.
(2) Since a locking projection protruding outward is provided on the middle circumferential side of the wheel case in the vertical direction, and the circumferential shape of the upper and lower wheel cases of this engagement projection is the same, the wheel member is reversed. When inserted into the insertion recess of the storage case, the non-wheel surface of the wheel member is positioned below the storage case, and the wheel member can be used as an adjuster for placing the storage case.
(3) Similarly, if the wheel member is inserted between the insertion recesses of the upper and lower storage cases, it can be used as a joint for coupling the upper and lower storage cases.
(4) As described above, since the wheel member can be used for multiple purposes, a plurality of members conventionally prepared according to each application are unified, and the manufacturing efficiency is rationalized, contributing to cost reduction. On the other hand, the consumer can freely recombine the combination and function of the storage case with one kind of member.
