Definitions

• the present invention relates to a doormat and an apparatus for producing the same.
• a doormat which has good cushiony effect by space due to corrugation of synthetic resin sheet when people coming and going step on it laid on a door or a gate, eliminates well muck from the outsole of shoes because of its good restoring force and elasticity, is also convenient to use and may prevent slip because of various convexities formed on the surface of corrugated band, and to an apparatus which comprises simple structure and is used in preparing easily the above doormat.
• the object of the present invention is to provide the doormat having excellent cushiony effect due to space formed by corrugation of synthetic resin sheet so as to solve the above problems of the doormats.
• Figure 1 is a perspective view of the doormat according to the present invention.
• Figure 2 is a side view of the above doormat.
• Figure 3 is a plane view of the above doormat.
• Figure 4 is a front view of the above doormat.
• Figure 5 is an alternative embodiment of the doormat according to the present invention.
• Figure 6 is a side view of the doormat represented in figure 5.
• Figure 7 is a plane view of the doormat represented in figure 5.
• Figure 8 is a front view of the doormat represented in figure 5.
• Each (A), (B), (C) and (D) of figure 9 is a plane view of the doormat prepared by band having various convexities on the surface thereof.
• Figure 10 is a schematic view of the apparatus for preparing the doormat according to the present invention.
• Figure 11 is a plane view of the roller of the above apparatus.
• Figure 12 is a plane view of the alternative roller of the above apparatus. Detailed Description
• the synthetic resin composition formed into the doormat according to the present invention must be composed of the materials which have excellent waterproofing, wear resistance, soluble property, elasticity and the likes.
• the example of organic polymers having such characteristics are polyvinyl chlorides, polyesters, polyuretha-ss, polypropylenes, polyethylenes, polystyrenes and various synthetic rubber.
• the illustrations in figure 1 to figure 12 more clearly show the preferred embodiment of the present invention.
• figure 1 which is a perspective view of the doormat according to the present invention
• the plural and continuous bands (bi) having 1 to 5M of thickness and 2 to 20-n of width are combined alternately with the straight bands (b 2 ) having 0.2 to 5n of thickness and 2 to 20M of width, or only the corrugated bands (b are combined in different phases to give the doormat of the figure 1.
• FIG. 2 is a side view of the above doormat, a corrugated band has different phase against next corrugated band and such corrugated bands having different phases with each other are combined alternately. As a result, holes are formed in space between the corrugated band (b and the straight band (b E ).
• the space due to phase difference of the above corrugated bands (bi) gives us good cushiony effect so that feeling is good at stepping on the above doormat. Also, since it has good restoring force and elasticity, muck adhered to the outsole of shoes is easily removed.
• Figure 3 is a plane view of the above doormat and figure 4 is a front view of the above doormat.
• Figure 5 is an alternative embodiment of the doormat according to the present invention. Since a width (hi) of the corrugated band (bi) may be differ from other width (hz) thereof, bending and stretching force is distributed. Accordingly, the doormat has better good feeling in use and it is fashionalble because of graceful external appearance.
• figure 6 is a side view, a plane view and a front view of the doormat represented in figure 5,
• figure 9 is an alternative embodiment of the doormat according to the present invention. Since A of figure 9 represents that convexities (d are horizontally formed on the surface of corrugated band (b and B represents that another convexities (4) are longitudinally formed on the surface of corrugated band (b . Also, C represents that convexities (da) are formed in all directions on the surface of corrugated band (b and D represents that dotted convexites such as the surface of orange are irregularly formed. Therefore, slip is prevented at trampling the corrugated band (bi) in using the doormat.
• the above doormats have good cushiony effect by space due to corrugation of synthetic resin sheet. Also, it eliminates well muck from the outsole of shoes because of its good restorinng force and elasticity. Furthermore, it is convenient and may prevent slip because of various convexities formed on the surface of the corrugated bands.
• Figure 10 is a schematic view of an apparatus for preparing the doormat according to the present invention.
• the synthetic resin sheet (8) formed from extrusion diced) passes between rollers(2, 3) having the plural protuberances(4, 4') in the lower part of extrusion dice(l), and then it is molded into corrugated shape. Next, it passes by guide roller(6) to take up by take-up roller(7).
• figure 11 is a plane view of the roller of the above apparatus. As illustrated in figure 11 which is a plane view of the roller, the drive roller(2) having plural corrugated protuberances (4) is meshed with the idle roller(3) having plural corrugated protuberandes (4') in the lower part of extrusion dice(l).
• the idle roller(3) is also rotated in attendance on rotation of the drive roller(2). alls(5, 5') are optionally established between protuberances and a corrugated protuberance(4) formed on the drive roller (2) crosses with the corrugated protuberance(4') formed on the idle drive(3). Since the guide roller(6) is placed near rollers(2, 3), the synthetic resin sheet passed by the guide roller (6) is taken up by take-up rolled7).
• FIG 12 is a plane view of the alternative roller of the above apparatus.
• the drive roller(2') having plural corrugated protuberances(4") is meshed with the idle roll ⁇ r(3') having plural corrugated protuberances(4"') in the lower part of extrusion dice(l).
• the idle roller(3') is also rotated in attendance on rotation of the drive roller (2').
• a corrugated protuberance(4") formed on the drive roller(2') crosses with the corrugated protuberance (4"') formed on the drive roller(3'). Since the guide roller(6) is placed near rollers(2', 3'), the synthetic resin sheet passed by the guide roller.6) is taken up by take-up roller(7).
• the doormat prepared by the above process may be cut in optional size according to use.
• the structure of apparatus for preparing the above doormat is very simple and the process for preparing the doormat is also easy in the case of use the above apparatus. Accordingly, efficiency of work can be accelerated and the doormat having good qualities can be prepared.
