Description

  The present invention relates to a bottom covering that can cover at least a bottom region of an article.

  In recent years, the number of travelers from overseas has been increasing. Travelers often carry their luggage in carry cases. Therefore, many carry cases are equipped with, for example, four wheels (casters) in the bottom area for the convenience of carrying. On the other hand, it is required to take off shoes at historical tourist places such as shrines and Buddhist temples and restaurants equipped with seats for user seating. This can often happen in Japan, where people have a habit of taking off shoes indoors.

  When a traveler goes to such a place, the aforementioned wheel-mounted carry case must be detained in a temporary storage. That is, the carry case must be separated from the hand. In particular, many Western travelers who rarely take off their shoes are not used to this. Such a situation can cause discomfort to travelers.

  In that case, if only the caster portion of the carry case can be covered, it is possible to prevent the dirt of the caster adhering to the outside from being transferred into the room. In addition, since the carry case can be placed close to itself, the possibility of theft can be greatly reduced, which contributes to the improvement of safety.

  On the other hand, even in articles other than carry cases, there is a great demand for covering only at least the bottom region. For example, if the bottom area of the article can be covered easily, the article can be prevented from rolling or provided with a sufficient buffer function. Further, if the above-described function can be achieved by covering only at the bottom region, material costs and covering work can be simplified as compared with the case where the entire article is covered. For example, the following Patent Documents 1 to 3 are disclosed as bottom covering bodies of such articles.

JP 2006-222006 A Utility Model Registration No. 3152207 Utility Model Registration No. 3141648

  The technique disclosed in Patent Document 1 relates to a single caster cover in which at least one area of a box-shaped rectangular parallelepiped is provided with a caster taking-out notch portion that is opened in an arc shape. Each caster is housed in the caster cover and is connected via a connecting member of each caster cover.

  The technology disclosed in Patent Document 2 includes a purse-like cap that is large enough to wrap one caster, and further includes a rubber-like elastic belt at the mouth edge (or in the vicinity of the mouth edge) of the cap. Regarding caster covers.

  The technique disclosed in Patent Document 3 is a cover in which casters can be placed in two places on the left and right sides of a main body, and a caster cover for a suitcase further comprising a rim, an inner side fastener, a tip round portion, and an outer side fastener About.

  However, all of the techniques disclosed in Patent Documents 1 to 3 individually protect individual casters. Therefore, in addition to many overall components, it takes time and effort to attach the cover to the caster.

  In addition, in any of the techniques disclosed in Patent Documents 1 to 3, when a caster-fitted article (carry case (bag), suitcase) is brought into the room, dirt adhered to the caster is attached and dropped. It is only intended to prevent contamination.

  By the way, in a crowded transportation system on the move, there are cases where a carry case is brought in as it is for the reasons described above. In that case, if a bottom covering like Patent Documents 1 to 3 is attached (covered) to the caster portion, the dirt will not move to other passengers or transportation interior members (seats or the like). However, since the transportation system moves at a suitable speed, centrifugal force at the time of curve and inertial force due to sudden start / stop are added.

  In that case, since the techniques according to Patent Documents 1 to 3 focus only on preventing the adhesion of dirt, they do not have other functions. As another function, for example, an anti-slip function can be cited, but the techniques according to Patent Documents 1 to 3 do not include the function. Therefore, when a centrifugal force or an inertial force is applied, it is impossible to prevent the carry case from moving out of control and colliding with another object. In addition, since the technologies according to Patent Documents 1 to 3 do not have a buffer function, the probability that the carry case is damaged after a collision cannot be reduced.

  In view of the above problems, an object of the present invention is to provide a bottom covering that can be easily attached to a bottom region of an article such as a carry case and can prevent transfer of dirt from the article. At the same time, the present invention aims to provide a bottom covering further provided with anti-slip and cushioning functions.

The bottom covering according to the present invention for solving the above problems is
Covering at least the bottom area of a carry case or four-year-old shopping cart with four wheels attached to the bottom area, covering all four wheels;
Provided with a bag-shaped covering main body with an opening edge,
The covering main body includes a plurality of protrusions including a buffer medium therein,
The protrusion is formed at least on the outer surface bottom region of the covering main body , and the carry case or the elderly shopping cart is brought into the transportation system and stands on the transportation seat with the four wheels. In the case where the centrifugal force of the curve or the inertia force due to sudden start / stop is applied, the anti-slip function is provided to resist the centrifugal force or the inertia force.
It is characterized by that.

In the bottom covering according to the present invention,
The protrusion is preferably formed on the entire outer surface and inner surface of the covering main body,
Furthermore, it is preferable to provide a tightening portion that is disposed along the opening edge and tightens a contact portion with the coated article.
Here, the tightening portion is preferably an annular rubber band.

  According to the present invention, since a bag-shaped covering main body portion having an opening edge is used, it is possible to provide a bottom covering body that can easily cover an article bottom region in one operation. In addition, according to the present invention, since it is provided with a tightening portion that is arranged along the opening edge and tightens the contact portion with the coated article, it is easy unless an appropriate force is applied artificially after being attached once. A bottom covering that is not removed can be provided.

  Furthermore, according to the present invention, since a plurality of protrusions filled with a buffering medium are provided in at least the outer surface bottom area and side area of the covering main body, a bottom covering body capable of simultaneously exhibiting an anti-slip function and a buffering function is provided. it can.

The figure which shows the use condition of one Embodiment which concerns on this invention. The perspective view of one Embodiment concerning the present invention. 1 is a partial cross-sectional view of an embodiment according to the present invention. Schematic which shows the other usage example (shopping cart which an elderly person uses) of this embodiment. Schematic which shows the other usage example (cup) of this embodiment.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be implemented in many different modes and should not be construed as being limited to the description of the embodiments described below.

  First, with reference to FIG.1 and FIG.2, the whole structure of the bottom cover 1 which concerns on one Embodiment of this invention is demonstrated. Here, FIG. 1 is a figure which shows the use condition of the bottom part covering body 1 which concerns on this embodiment. FIG. 2 is a perspective view of the bottom covering 1 according to the present embodiment.

  FIG. 1 shows, as an example, a bottom covering 1 that can cover at least a bottom area 110 of a carry case 100 used by a traveler or a business person to carry his / her luggage. The bottom cover 1 covers the bottom region 110 to simultaneously cover the casters (wheels) 130 </ b> A to 130 </ b> D attached to the bottom region 110.

  Further, in the example shown in FIG. 1, the bottom cover 1 covers the lower side (bottom side) of the side region 120 of the carry case 100, but is not limited thereto, and can cover at least the casters 130. If it is an aspect, it may not be possible to cover up to the side region 120. However, as will be described later, the bottom cover 1 is attached to the carry case 100 so as not to be easily detached by the fastening portion 3 such as a rubber band. Therefore, it is preferable that the bottom covering 1 is in a mode capable of covering a part of the side region 120 of the carry case 100 as shown in FIG.

  Next, as shown in FIGS. 1 and 2, the bottom covering 1 according to the present embodiment includes a covering main body 2, a tightening portion 3, and a protrusion 4. Here, the covering main body 2 is a bag-like member having a form similar to a so-called shampoo hat so that at least the bottom region 110 of the carry case 100 can be covered. Further, the covering main body 2 includes a circumferential opening edge 21.

  The covering main body 2 is preferably flexible so that it can be easily attached to any of the bottom regions of the carryback 100 that may have various shapes. Although the raw material of the coating | coated main body part 2 is not specifically limited, For example, a polyethylene resin etc. can be considered.

  However, the material of the covering main body 2 is not limited to this, and may be another resin. Further, the material is not limited to resin, and may be fabric material, fiber material such as woven fabric / nonwoven fabric, paper material, or a mixture thereof.

  By using a highly versatile resin that can be mass-produced such as polyethylene, it is possible to reduce the manufacturing cost, and it is also possible to dispose it once used. As a result, even if the bottom cover 1 is damaged for some reason, it can be easily replaced with a new one. In addition, since the provider of the bottom cover 1 can easily distribute it to the recipient (traveler or the like), it can contribute to increasing the added value of the provided service.

  The covering main body 2 shown in FIG. 1 and FIG. 2 is formed into a bag shape seamlessly using, for example, one sheet-like material, but the form of the covering main body 2 is limited to this. is not. For example, a box-like form provided with a bottom surface and four side surfaces and each surface connected by a predetermined means may be used. At that time, the upper edge of each side surface corresponds to the opening edge 21.

  Next, as shown in FIG. 1 and FIG. 2, the tightening portion 3 is disposed along the opening edge 21 and is used for tightening a contact portion with the article to be coated (for example, the carry case 100). . The tightening portion 3 in the present embodiment is a rubber band, but is not limited thereto. You may use the other member which can be elastically expanded-contracted like a rubber band.

  The attachment method of the fastening part 3 (rubber band) is arbitrary. As an example, a method may be considered in which a hollow tunnel portion is provided in the opening edge 21 or in the vicinity thereof, and a rubber band is attached along the opening edge 21 by inserting a rubber band into the tunnel portion.

  As another example, a method of attaching a rubber band to the opening edge 21 or its vicinity using a pair of snap tools may be used. In this case, the male part of the snap tool is attached to the rubber band, and the female part is attached to the opening edge 21 or its vicinity (of course, the arrangement of the male part and the female part may be reversed). The rubber band is attached by fitting (engaging) the male part and the female part. Of course, other than these may be used as the attachment method.

  Next, as shown in FIG. 2, a plurality of protrusions 4 are formed over the entire outer surface 22 and inner surface 23 of the covering main body 2. Details of the protrusion 4 will be described with reference to FIG. 3. Here, FIG. 3 is a partial cross-sectional view of the bottom covering 1 according to the present embodiment.

  As shown in FIG. 3, each protrusion 4 has a hollow shape and includes a buffer medium therein. The form of the protrusion 4 is not particularly limited as long as the buffer medium can be sealed. In addition, the size and the number are not limited as long as the corresponding buffer function can be achieved.

  The buffer medium in the protrusion 4 includes air, but is not limited to this as long as it has a corresponding buffer function. The protrusion 4 may be integrated with the outer surface 22 and the inner surface 23 of the covering main body 2 or may be separated from the covering main body 2 at the beginning. When separated, the protrusion 4 is connected to the covering main body 2 by any fixing means.

  In the example shown in FIG. 3, the protrusions 4 are formed on both the outer surface 22 and the inner surface 23 of the covering main body 2, but are preferably formed on at least the outer surface 22. Further, the protrusion 4 is preferably formed in the bottom region 221 and the side region 222 of the outer surface 22.

  The protrusion 4 formed in the bottom region 221 of the outer surface 22 is a place that can come into contact with the ground (floor surface). As shown in FIG. 3, the concavo-convex structure is repeatedly formed on the outer surface 22 by the plurality of protrusions 4. That is, by providing the plurality of protrusions 4 on the outer surface 22 as compared with a flat structure in which the protrusions 4 are not formed, the contact area with the ground is significantly increased. As a result, the contact area with the ground increases and the frictional resistance increases. That is, a good anti-slip function is provided by the plurality of protrusions 4.

  With such a configuration, the present invention can simultaneously exhibit an anti-slip function and a buffer function. Moreover, although this embodiment shown by FIGS. 1-3 has employ | adopted the carry case 100 as a covering object article, it is not restricted to this. The article to be covered may be a suitcase. For example, the shopping cart 200 for elderly people, a cup 300, etc. may be sufficient as shown in FIG.4 and FIG.5. Further, the article to be covered may be a stroller carrying an infant. As described above, the bottom covering 1 is preferably used for articles to be coated having various sizes. Therefore, the size (width dimension, depth dimension, etc.) and shape of the bottom cover 1 are not particularly limited. As shown in FIGS. 4 and 5, the bottom cover 1 covers the bottom region 210 of the elderly shopping cart 200 and the bottom region 310 of the cup 300.

  Next, a method for attaching the bottom covering 1 according to the present embodiment (covering the article bottom region) will be described. As described above, the carry case 100 will be described as an example of the article to be covered. When covering the bottom case 1 with the carry case 100, the user first widens the opening edge 21 of the covering main body 2. As described above, the elastic band that can be elastically expanded and contracted (tightening portion 3) is disposed at the opening edge 21. Therefore, the opening edge 21 expands with a restoring force that acts on the side opposite to the expansion direction. The operation of expanding the opening edge 21 may be manual or mechanical means may be used.

  Next, the user inserts the carry case 100 into the bottom cover 1 from the opening edge 21 after facing the opening edge 21 and the bottom area 110 of the carry case 100 facing each other. Further, the user raises the height position of the opening edge 21 and increases the coverage area of the carry case 100 by the bottom cover 1. At this time, the bottom cover 1 covers not only the bottom region 110 of the carry case 100 but also the lower side of the side region 120.

  The entire bottom region 110 of the carry case 100, that is, all of the plurality of casters 130 attached thereto are covered with one bottom covering 1. Further, the rubber band (clamping portion 3) tightens the contact point with the carry case 100 (in the figure, the side region 120 of the carry case 100) by its restoring force. As a result, the bottom cover 1 is not easily removed from the carry case 100 unless a corresponding force is artificially applied.

  As described above, according to the bottom cover 1 according to the present embodiment, after the opening edge 21 is widened, the bottom cover 1 is only covered with at least the bottom region 110 of the carry case 100 (covering target article). The entire bottom region 110 can be covered. As a result, it is possible to cover all of the casters 130 attached thereto by an extremely simple operation.

  When the bottom cover 1 is removed from the carry case 100, the user widens the opening edge 21 and releases the tightening of the carry case 100 by the rubber band. Thereafter, the user moves the bottom cover 1 to the lower side of the carry case 100. Finally, the carry case 100 is discharged from the opening edge 21 to the outside of the bottom cover 1. Thereby, the bottom cover 1 can be removed from the carry case 100.

  Similarly, the removal of the bottom cover 1 can be performed by a very simple operation. That is, the bottom covering 1 according to the present invention functions extremely beneficially when the covering work of the article to be coated must be performed within an impending short time.

  In the above, one embodiment of the present invention has been described. However, the above description is for facilitating the understanding of the present invention, and is not described for the purpose of limiting the present invention. The present invention may include modifications and improvements that can be made without departing from the spirit of the present invention. Further, the present invention includes equivalents thereof.
