Japanese Patent No. 3409299 JP 10-33291 A JP 2009-185526 A

  By the way, since the corner cushions shown in Patent Document 1 and Patent Document 3 are both long in the vertical direction and the actual dimensions are approximately 2100 mm, it is difficult to perform the work of attaching the upper side of the corner cushion to the attachment object. In addition, there are a lot of attachment objects as large as 2100 mm, especially at a construction site, and part of the corner cushion tends to be discarded, which is wasteful. Moreover, since it is necessary to inject | pour a foaming agent in the work site, patent document 2 cannot anticipate quick installation work. Both proposals are developed exclusively for corner cushions.

  As a result of various examinations of these conventional proposals, the present invention is not only used as a cushioning material suitable for curing / protection sheets, leisure sheets etc. used in construction sites, etc. We have come to develop a corner cushion that can be used.

  Therefore, the problem to be solved by the present invention is not limited to the cushioning material suitably used for the curing / protection sheet, leisure sheet etc. used in the construction site, the inspection work site, the moving work site, etc. It is to provide a corner cushion that can be installed neatly.

  In order to solve the above technical problems, the cushioning material according to the present invention is formed between the water-resistant back sheet cover and the water-resistant back sheet cover, which are long in the lateral direction. A plurality of strip-shaped cushioning materials having slightly shorter vertical dimensions are arranged side by side along the vertical direction of the seat cover and at predetermined intervals in the horizontal direction, and the top sheet The cover and the back sheet cover are bonded and fixed to each other at the upper, lower, left, and right end portions thereof and at the predetermined space between the cushioning materials, and are configured to be foldable and expandable in a bellows shape at the predetermined space. (Claim 1).

  In the cushioning material, the cushioning material according to claim 1 is provided with one or a plurality of ventilation paths in communication with the storage space of the respective cushioning material in the adhesive fixing portion at the lower end of the front seat cover and the rear seat cover. (Claim 2).

  In the cushion material, the cushioning material of the cushion material according to claim 1 may be a foamed resin material having closed cells (claim 3).

  Moreover, in order to achieve said objective, the corner cushion by this invention is a short width by cut | disconnecting the site | part which vacated the predetermined space | interval of the cushioning material of any one of Claims 1-3 to the vertical direction. Thus, it can be attached to an attachment object via an attachment element (claim 4).

  In the devices according to claims 1 to 4 of the present invention, it goes without saying that the cushioning material is suitably used for a curing / protection sheet used in a construction site, an inspection work site, a moving work site, etc., and also a leisure sheet. A corner cushion that can be installed neatly with the above is obtained.

  That is, the cushion material and the corner cushion of the invention according to claims 1 to 4 can be carried in a compact and compact manner by folding in a bellows shape at a predetermined interval along the vertical direction. Also, it can be applied to form a sheet with a predetermined floor area by spreading, for example, on-site floor curing and leisure sheets, and also as a floor mat. It is also suitably applied to curing. In addition, by cutting the cushion material at a predetermined interval in the vertical direction to make it a short horizontal width so that it can be attached to the object to be attached via an attachment element, work on construction sites, construction, and renovation It can be effectively used as a safety cushion in the field and as a corner cushion for other pillars that need to prevent damage when moving. As the attachment element for attaching the corner cushion to the attachment object, various known elements such as a double-sided adhesive tape, a magnetic sheet cut into a thin strip and pasted on the back surface of the sheet, and an adhesive are used.

  Further, in the invention according to claim 2, one or a plurality of ventilation paths are provided at the adhesive fixing portions at the lower ends of the top sheet cover and the back sheet cover so as to communicate with the storage spaces for the respective cushioning materials. Therefore, the storage space of the substantially sealed buffer material can be communicated with the outside air by this ventilation path, and even if the air in the storage space of the buffer material expands in the summer, it can be exhausted to the outside. As a result, it is possible to successfully eliminate the possibility that the cushion material will expand, and also to prevent rainwater from entering well and maintain a beautiful appearance for many years.

Furthermore, in the invention according to claim 3, since the cushioning material of the cushion material is formed of a foamed resin material having closed cells, even if rainwater or moisture enters, they penetrate into the cushioning material. There is no risk of aging deterioration of the cushioning material, and there is little risk of damaging the appearance in the early stage, and a beautiful appearance can be maintained for many years.

  Furthermore, in the device according to claim 4, the cushion material according to any one of claims 1 to 3 is cut at a predetermined interval in the longitudinal direction to make a short lateral width and attached to the attachment object. Since it was attached via an element, for example, in order to ensure safety by surrounding the corners of obstacles such as pipes and pillars at construction sites and construction sites, etc. Unlike corn-cushion, it is small and easy to handle, easy to install, and saves waste.

  In addition, the cushion material in the present invention includes, for example, the above-mentioned corner cushions, a sheet for temporary storage of tools, a floor curing mat when using a stepladder, a liquid drop receiving sheet when painting paint, a building material and furniture, etc. This includes simple curing materials for covering the floor and covering the floor when carrying in, etc., and mats used in shelters in the event of a disaster. It can contribute to convenience at many sites and environments.

The Example of the cushioning material which concerns on this invention is shown, It is a partially notched whole external view. It is sectional drawing of the principal part cut | disconnected along the vertical direction. It is sectional drawing of the principal part cut | disconnected along the horizontal direction. It is a description external view of a use state. It is an external view which shows a folding storing attitude | position. It is an expanded sectional view of the principal part which shows a 2nd Example and shows the structure of a ventilation path. The action figure which obtains the corner cushion of 3rd Example is shown, (A) is an external view which shows cutting work, (B) is the completion figure of a corner cushion. It is explanatory drawing of an effect | action when mounting | wearing a corner cushion with a corner cushion.

  Hereinafter, the form at the time of applying the cushioning material of this invention to the curing material of a sill in a construction site is demonstrated with reference to an accompanying drawing.

  The cushion material 1 is arranged in a laterally long front seat cover 2 and rear seat cover 3 and a basically closed storage space 4 formed between the two seat covers 2 and 3. It is comprised from the provided shock absorbing material 5

  The front sheet cover 2 and the back sheet cover 3 that are long in the lateral direction are thin-walled sheets made of a flexible synthetic resin having the same dimensions of flexibility and water resistance. Configure each one. Polyvinyl chloride tarpaulin (PVC tarpaulin) or the like is adopted as an example of a flexible synthetic resin material having flexibility, water resistance and strength, but is not particularly limited as long as it has similar properties. These front and back seat covers 2 and 3 completely cover the front and back, top and bottom, left and right of the cushioning material 5. Incidentally, the front surface is 700 mm in the vertical direction (up and down direction on the paper surface of FIG. 1) of the sheet cover 2 and the back sheet cover, and the width direction (left and right direction on the paper surface of FIG. 1) is 1850 mm in the extended state.

  The cushioning material 5 is a member that gives the cushion material 1 a function as a cushion, and is preferably a closed cell synthetic resin material. Specifically, foamed polyethylene (EPE) is adopted, but as long as it has the above properties, an open-cell synthetic resin material, further, a corrugated plastic, etc. may be used. is not.

  The buffer material 5 is formed in a rectangular strip shape with a length of 695 mm in the vertical direction and a width of 190 mm in the horizontal direction, and has a thickness of 5 mm. The cushioning material 5 has a total of eight sheets, each of which has its longitudinal direction along the longitudinal direction of the front and back sheet covers 2 and 3 and a predetermined distance in the lateral direction, specifically 20 mm away from each other. 3 are arranged in parallel, and the portion 10 with the predetermined gap between the upper and lower and left and right end portions 6, 7, 8, 9 of each of the front and back sheet covers 2, 3 and each cushioning material 5 is heat-melted. By integrally bonding and fixing by wearing, eight cushioning materials 5 are sealed and accommodated in the independent storage space 4. The shock-absorbing material 5 is not integrated with the front and back seat covers 2 and 3 by the heat fusion but is independent.

  The cushion material 1 is simply folded into a bellows shape through the predetermined portion 10 because the portion 10 having the predetermined interval is only the thickness of the two front and back seat covers 2 and 3. The sill 11 is used for storage, storage or carrying, and is spread to a predetermined area and covered so as to straddle the sill 11, so that the sill 11 is cured well.

  As shown in FIG. 4, the cushion material 1 configured in this way is covered with a mat having a predetermined width so that the cushion material 1 covers the sill 11 at a construction site. For example, it is possible to successfully prevent the sill 11 from being damaged when carrying materials, standing furniture, and the like, and the sill 11 can be cured well. Further, when storing, storing or transporting, as shown in FIG. 5, the portion 10 having a predetermined interval is thin with a thickness corresponding to two sheets of the front and back seat covers 2 and 3, so this predetermined interval is set. The space 10 can be easily folded, and by repeatedly folding the space 10 with a predetermined interval between the front and back and the front and back, the width can be folded to be as narrow as that of the single rectangular cushioning material 5. In addition to being easy to carry and handle, it can be stored and stored with low bulk.

  In the example shown in the figure, the cushioning material 5 is a strip shape and 8 pieces are independently employed. However, if necessary, a wide material in which 8 pieces are almost integrated is adopted, and the front and back seat covers are used. 2 and 3, and when the front and back sheet covers 2 and 3 are integrally bonded by thermal fusion, the cushioning material 5 is also softened and fused by thermal fusion at intervals equal to the strip shape. Can be integrated. The buffer material 5 at the heat-sealed part is melted and thinned, and has the same thickness as the part 10 having the predetermined interval similar to that shown in FIGS. It is possible to bend or stretch freely at the site 10. Even with such a configuration, the same effects as those using the cushioning material 5 which is a separate body can be exhibited.

Next, the structure shown in FIG. 6 shows a modification, and is provided with a function for releasing the air in the storage space 4 of the cushioning material 5 to the outside air.
That is, in the heat sealing part 12 of the lower end 7 of the top sheet cover 2 and the back sheet cover 3 of the cushioning material 1, a predetermined interval in the lateral direction is provided at a plurality of locations (three locations in the example), One end is connected to the storage space 4 and the other end is connected to the outside air to form unheated fusion portions 13 having substantially the same width. The unheated fusion portion 13 communicates with the storage space 4 of the cushioning material 5 and the outside air. It is formed in the ventilation path 14 to be performed. If the air in the storage space 4 is heated and expands in summer or the like, the expanded gas is discharged to the outside air through the ventilation path 14. Therefore, the possibility that the cushion material 1 expands can be solved well, and intrusion of rainwater can be prevented well, and a beautiful appearance can be maintained for many years.

  Note that the ventilation path 14 may be the upper end 6 when the cushion material 1 is used, for example, when used in a place where it is not exposed to rainwater, such as for indoor use. If it is provided at the lower end portion 7, rain can be prevented from entering, which is convenient for outdoor use. Moreover, the said ventilation path may be one.

Next, the case where this cushion material 1 is used as the corner cushion 15 will be described with reference to FIGS.
Since the cushion material 1 has a structure in which thin portions at predetermined intervals in the width direction, that is, the portions 10 of the buffer material 5 with the predetermined intervals are present, as shown in FIG. A partial cushion material 1A having a narrow width is obtained by cutting the portion 10 having an appropriate width as needed, such as one sheet or two sheets of the material 5 and having an appropriate width. As shown in FIG. 7B, the back cushion cover portion 3B of the obtained partial cushion material 1A was cut into a double-sided adhesive tape or a predetermined width along the vertical direction with a predetermined interval in the horizontal direction. An attachment element 16 represented by a magnet sheet or the like is attached. In the example shown in the figure, a double-sided adhesive tape is used. In the figure, reference numeral 17 denotes a release paper.

  The partial cushioning material 1A thus obtained is provided with the mounting element 16 at a corner 18, such as a pillar, pipe or steel shape, in order to ensure the safety of workers at construction sites, construction sites, and remodeling sites. Therefore, it can be effectively used as a corner cushion 15 as a protective measure for safety, and as a corner cushion 15 for a column or the like that needs to prevent damage when moving. When the height is insufficient, as shown in FIG. 8, the cushion material 1 is further cut from the portion 10 having a predetermined width and the predetermined interval, so that the corner cushion 15 previously attached is attached. By attaching it to the upper part, the height can be extended as desired, and unlike the conventional case, there is an advantage that it is easy to reduce the waste of the material.

  Each embodiment described above is not necessarily limited to the structure shown in the drawings, and the individual structures and shapes shown can be combined with each other or used within a scope not contradicting the gist of the invention. Further, the cushion material 1 according to the present invention includes the corner cushion 15 and the like, for example, a sheet for temporary storage of tools, a floor curing mat when using a stepladder, a droplet drop receiving sheet when painting, and a disaster. Some mats are sometimes used in shelters, etc., which can contribute to convenience in many sites and environments with simple construction that is simply laid on the floor.
