Description

  The present invention relates to a protective film that is attached to the surface of a vehicle such as an automobile, a motorcycle, or a bicycle to protect the surface of the vehicle or the inside of the surface.

  In general, in a cold region where the temperature falls below freezing point, if a vehicle such as an automobile, a motorcycle, or a bicycle is left outdoors, frost or ice may adhere to the surface of the vehicle. For this reason, when using the vehicle, the vehicle user needs to remove frost and ice attached to the window glass, the transparent part of the cowl, the part directly used for driving the vehicle, such as a handle or a seat. . In this case, an operator who removes a frozen portion such as frost or ice removes the frozen portion by placing boiling water on the frozen portion or thawing the frozen portion by heat from the vehicle warm-up operation. Yes.

  However, in the work of melting the frozen part using hot water, it is necessary to prepare an amount of hot water corresponding to the frozen part of the window glass and to wipe off the hot water. There is a problem that post-treatment of hot water takes time and effort. In particular, when it is necessary to melt and remove a plurality of vehicles, it takes much time and labor. Also, in a vehicle in which the bonnet is not formed in the front part of the vehicle, for example, a light truck, a large amount of hot water applied to the windshield is likely to be applied to the operator's feet, so the work of applying hot water There is also a problem that the property is extremely bad. On the other hand, there is a problem that it takes time to thaw the frozen portion even in the operation of melting the frozen portion with heat generated by the warm-up operation of the vehicle. Such a melting operation of the frozen portion is often necessary mainly in the morning in winter, and therefore there is a problem that the work burden is large in the morning time zone with a small time margin.

  In view of this, for example, Patent Documents 1 and 2 below propose protective films mainly for preventing adhesion of frost, ice, and the like to the windshield of an automobile. This protective film prevents frost, ice, and the like from directly adhering to the vehicle by attaching a film body in advance to a portion such as a windshield of an automobile where it is desired to avoid adhesion of frost, ice, or the like. Therefore, an operator who removes a frozen portion such as frost or ice can remove the frozen portion such as frost or ice easily and in a short time by simply peeling off the previously attached film body from the vehicle surface.

  However, in such a protective film, since the adhesive portion is formed on the inner surface of the roll body in the long film body wound in a roll shape, the work of attaching the film body to the adherend portion in the vehicle There is a problem that it is difficult to do. In general, in order for an operator to attach a film body to an adherend portion in a vehicle, one end of the film body drawn from the roll body is attached to one end side of the adherend portion, and then the roll body is held with one hand. Then, while the film body is being sent out, the other body is rubbed against the film body that has been fed onto the adherend portion, and the pasting operation is performed toward the other end side of the adherend portion. That is, the film body pasting operation must be performed with both hands, and the work load is large. In addition, when the adherend is a long surface such as a windshield of an automobile, the roll body must be held for a long time while reaching out, further increasing the work burden on the operator. Become.

  In addition, when affixing the film body along the longitudinal direction of the windshield, the operator changes the standing position on the right side (driver's seat side) and the left side (passenger seat side) of the windshield, respectively. It is necessary to attach. In this case, the worker often changes the standing position in a state where the roll body connected to the film body attached to the windshield is temporarily placed near the center of the windshield. However, since the windshield is composed of a curved surface with an inclined surface, the roll body placed on the windshield is in an extremely unstable state. For this reason, when an operator changes a standing position, the position and attitude | position of the roll body mounted on the windshield may shift | deviate unexpectedly, and a wrinkle and wrinkle may arise in a part of film body pulled out from the roll body. At the same time, there is a problem that the workability and the finished state of pasting of the film body are significantly impaired due to the film bodies sticking to each other.

  The present invention has been made to cope with the above-mentioned problems, and its purpose is to be able to easily and quickly apply a good finished state even if the adherend portion of the vehicle is long like a windshield. It is to provide a protective film that can be used.

  In order to achieve the above object, a feature of the present invention according to claim 1 is that the protective film is attached to the surface of a vehicle and protects the same surface or the inside of the surface, and has a long film body having flexibility. An adhesive material for attaching the film body to the surface of the vehicle has an adhesive part applied to one surface of the film body, and the film body has the one surface in the film body on which the adhesive part is formed. A roll body is formed by being wound in a roll shape so as to be exposed to the outside.

  According to the feature of the present invention according to claim 1 configured as described above, the roll body in which the long film body is wound in a roll shape is affixed to the surface on the side exposed to the outside of the roll body. An adhesive portion is formed. For this reason, the roll body can be adhered to the adherend portion by the roll body itself. Therefore, an operator who attaches the film body to the surface of the vehicle can attach the roll body while pulling out the film body by rolling in the direction in which the film body is attached in a state where the roll body is attached to the adherend. In this case, since the roll body is adhered to the adherend portion by the adhesive portion formed on the surface of the film body, the roll body is adhered to the adherend portion even if the operator releases the hand from the roll body. The position and posture of the camera will not shift unexpectedly. As a result, even if the adherend in the vehicle is long like a windshield, it can be attached in a good finished state easily in a short time.

  Another feature of the present invention according to claim 2 is that, in the protective film, the protective film is, for example, for preventing freezing of the surface of the vehicle.

  According to the other feature of the present invention according to claim 2 configured as described above, the work of attaching the film body to the portion where frost and ice adhesion in the vehicle is desired to be avoided can be performed easily and in a short time. The finished state can be improved.

  Another feature of the present invention according to claim 3 is that, in the protective film, the surface of the vehicle is, for example, a window portion in the vehicle.

  According to another feature of the present invention according to claim 3 configured as described above, the work of attaching the film body to the window portion in the vehicle can be performed easily and in a short time, and the finished state is improved. Can do. In this case, in particular, even if the adherend in the vehicle is long like a windshield, the film body can be attached in a good finished state easily and in a short time.

  Moreover, the other feature of the present invention according to claim 4 is that, in the protective film, the adhesive portion is partially formed along the whole or the longitudinal direction of the one surface of the film body. .

  According to the other characteristic of this invention which concerns on Claim 4 comprised in this way, the adhesion part is partially formed along the whole one surface of a film body, or the elongate direction. In this case, when the adhesive portion is formed on the entire surface of one surface of the film body, the film body can be firmly attached to the adherend portion, and the adherend portion and the film body after the film body is attached Foreign matter can be prevented from entering between the two. Moreover, since the adhesiveness to the adherend of the film body is high, for example, the field of view can be secured even when the film body is stuck on the windshield of the vehicle, and the vehicle can be used without peeling off the film body. In addition, since the entire surface of the film body is adhered to the adherend part, when the film body is peeled off from the adherend part, deposits such as sand and dust attached to the adherend part to which the film body is adhered are removed. It can be removed at the same time, and the effect of cleaning the adherend can also be expected.

  On the other hand, when the adhesive part is partially formed on one surface of the film body, the adhesive strength of the film body is weaker than in the above case, so the film body can be easily attached and peeled off. Become. Moreover, since the usage-amount of the adhesive material which comprises an adhesion part decreases, a protective film can be produced economically. In addition, by forming the adhesive portion on both end sides in the width direction of the film body, the operator can avoid touching the adhesive portion by gripping the central portion in the axial direction of the roll body. Workability of pasting work is improved.

  Further, another feature of the present invention according to claim 5 is that in the protective film, the film body is transparent.

  According to the other characteristic of this invention which concerns on Claim 5 comprised in this way, since the film body was comprised transparently, even if it was in the state which affixed the form body, the film body was affixed The adherent part and the inside of the adherent part can be visually recognized. Therefore, for example, the field of view can be ensured even when attached to the windshield of the vehicle, the vehicle can be used without peeling off the film body, and the inside of the vehicle can be confirmed from outside the vehicle.

  Further, another feature of the present invention according to claim 6 is that in the protective film, the film body is translucent or opaque.

  According to the other characteristic of this invention which concerns on Claim 6 comprised in this way, the film body is comprised translucent or opaque. For this reason, in the state which stuck the form body, the adhesion part to which the film body was affixed, and the inner side of the adhesion part cannot be visually recognized directly. Thereby, when a film body is affixed to the window part in the vehicle, the privacy inside the vehicle can be ensured. In this case, by configuring the color of the film body with a black color that easily absorbs heat, it is possible to mitigate deterioration of components due to temperature rise in the vehicle and sunlight, and frost and ice adhere to the film body When it is done, it can be naturally melted early by sunshine. Moreover, since it can recognize easily that the film body has affixed, it can also prevent forgetting to peel off a film body.

  Another feature of the present invention according to claim 7 is that in the protective film, the film body has at least one of a perforation, a cut line and a crease for cutting the film body. .

  According to the other characteristic of this invention which concerns on Claim 7 comprised in this way, at least 1 of the perforation, cut | interruption, and crease | fold for cut | disconnecting a film body to predetermined | prescribed length and shape is included in a film body One is formed. Thereby, the operator can cut | disconnect a film body easily to suitable length and shape, without using cutting tools, such as a scissors and a cutter. As a result, workability and safety for attaching the film body can be improved.

  Hereinafter, an embodiment of a protective film according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view schematically showing an overall configuration of a protective film 10 according to the present invention. In addition, each figure referred in this specification is expressed typically, such as exaggerating some components, in order to facilitate understanding of the present invention. For this reason, the dimension, ratio, etc. between each component may differ. This protective film 10 is for affixing to window glass in vehicles, such as a motor vehicle (not shown), and preventing that frost and ice adhere to a window glass.

(Configuration of protective film 10)
The protective film 10 includes a roll body 13 in which a film body 12 is wound around a core body 11. The core body 11 is a component that constitutes the core portion of the roll body 13, and is composed of a long and narrow cylindrical body made of paper. In this embodiment, the outer diameter is about 20 mm, the inner diameter is about 10 mm, and the length is about 400 mm. The film body 12 is a strip-shaped thin film body that is affixed to a window glass of a vehicle, and is made of a transparent polyethylene material. In this embodiment, the thickness is about 60 μm, the width is about 400 mm, and the length is about 15 m. In addition, the size (about 400 mm) in the width direction of the film body 12 in the present embodiment was set based on a size capable of ensuring a minimum necessary field of view in a general private automobile windshield.

  An adhesive portion 14 is formed on one surface 12 a of the film body 12. The adhesive portion 14 is a thin film layer in which an adhesive material is applied to the entire surface of one surface 12 a of the film body 12. In this case, the adhesive material can easily attach the film body 12 to an adherend portion such as a window glass in a vehicle, and the film body 12 is removed in a state where the adhesive material does not remain on the adherend portion. It is comprised by the component of the resin type | system | group (In this embodiment, an acrylic adhesive material) which has the adhesive force of the grade which can do. In addition, in each figure referred in this specification including FIG. 1, in order to clarify the formation part of the adhesion part 14, while showing the surface where the adhesion part 14 appears on the front side by hatching by a point group, the film body 12 is rolled. It is shown in a state where it is pulled out from the body 13. Moreover, the edge part which the adhesion part 14 appears on the front side is shown with the broken line, and the edge part which appears on the back side is shown with the dashed-two dotted line (imaginary line).

  The film body 12 on which the adhesive portion 14 is formed is wound around the outer peripheral surface of the core body 11 in a roll shape so that the one surface 12a on which the adhesive portion 14 is formed is exposed to the outside. In this case, the film body 12 wound around the core body 11 is wound in a roll shape in a state in which the other surface 12b of the film body 12 is stuck on the adhesive portion 14 formed on the one surface 12a of the film body 12. It is burned. For this reason, the film body 12 wound around the core body 11 is not naturally unwound and maintains the state wound in a roll shape.

(Operation of the protective film 10)
Next, the operation of the protective film 10 configured as described above will be described. First, the operator prepares the protective film 10. Next, as shown in FIG. 2A, the operator holds the roll body 13 in the hand H and stands on one side (the left side (driver's seat side) in the figure) of the side of the windshield 20 in the vehicle. The roll body 13 of the protective film 10 is placed on one end (the left end in the figure) of the windshield 20 in the longitudinal direction. In this case, the operator places the film body 12 on the windshield 20 in a direction (the vertical direction in the drawing) in which the axial direction of the roll body 13 is orthogonal to the longitudinal direction of the windshield 20. Further, the worker places the end of the film body 12 wound by the roll body 13 with the end facing the windshield 20 side. Thereby, the edge part of the film body 12 sticks to the edge part of the windshield 20. FIG.

  Next, an operator rolls the roll body 13 affixed on the windshield 20 toward the other end part side (arrow direction shown in the drawing) of the windshield 20. Thereby, the roll body 13 is displaced toward the other end of the windshield 20 while the film body 12 is peeled off from the roll body 13. Further, the film body 12 peeled off from the roll body 13 is sequentially attached to the surface of the windshield 20 according to the displacement of the roll body 13.

  It should be noted that the operation of attaching the film body 12 by rolling the roll body 13 can be basically performed only by an operator's one-hand operation. However, if necessary, the film body 12 attached to the surface of the windshield 20 can be rubbed by hand, so that the film body 12 can be more closely attached to the surface of the windshield 20.

  Then, as shown in FIG. 2 (B), the operator rolls the roll body 13 to the vicinity of the central portion of the windshield 20, and on the other side of the windshield 20 (right side (passenger seat side in the figure)). )) To change the standing position. In this case, the roll body 13 located in the vicinity of the center portion of the windshield 20 is in a state in which the hand is separated from the operator. However, since the roll body 13 on the windshield 20 is adhered to the surface of the windshield 20 by the adhesive portion 14, the position and posture of the roll body 13 are not unexpectedly shifted. Thereby, a twist and a wrinkle do not arise in a part of film body 12 pulled out from roll body 13, and film bodies 12 do not stick together.

  Next, as shown in FIG. 2 (C), the worker who has changed the standing position to the other side of the windshield 20 moves the roll body 13 attached near the center of the windshield 20 to the windshield. 20 is drawn while rolling toward the other end side (front side of the operator) (in the direction of the arrow in the figure). Also in this case, the roll body 13 is displaced toward the other end portion of the windshield 20 while the film body 12 is peeled off as described above. Further, the film body 12 peeled off from the roll body 13 is sequentially attached to the surface of the windshield 20.

  When the roll body 13 is pulled toward the other end side of the windshield 20, the operator cuts and cuts the film body 12 connected to the roll body 13 using a cutting tool such as a cutter. The end portion of the film body 12 is attached to the windshield 20. Thereby, as shown in FIG. 3, the operation of attaching the film body 12 to the windshield 20 is completed.

  In the present embodiment, the length of the film body 12 constituting the roll body 13 is 15 m. In this case, when the film body 12 is affixed to the windshield 20 in a general automobile, the length corresponding to the usage amount for 10 times when the usage amount for one time is about 1.5 m is used. Therefore, what is necessary is just to determine the length of the film body 12 suitably according to the usage-amount, usage frequency, etc. of 1 time.

  Thus, in a vehicle in which the film body 12 is attached to the surface of the windshield 20, frost or ice adheres to the surface of the film body 12 by being placed in an environment below freezing. Therefore, the operator can remove frozen parts such as frost and ice attached on the windshield 20 easily and in a short time by peeling off the film body 12 stuck on the windshield 20. In this case, if deposits such as dust exist on the surface of the windshield 20, the deposits are removed from the windshield 20 together with the film body 12 by peeling the film body 12 from the windshield 20. . As a result, the visibility through the windshield 20 is improved, and the driving safety of the vehicle can be improved. That is, when the operator attaches the film body 12 to the windshield 20, the operator attaches the film body 12 onto these deposits without removing the deposits attached to the surface of the windshield 20. Can do. On the other hand, the film 12 peeled off from the windshield 20 may be discarded according to a disposal method corresponding to the type of material.

  In addition, since the film body 12 is comprised transparently, when frost, ice, etc. do not adhere to the surface of the film body 12, the vehicle is attached with the film body 12 attached to the surface of the windshield 20. It can also be used (operated). That is, the film body 12 attached to the windshield 20 may be peeled off when the visibility of the windshield 20 cannot be ensured.

  As can be understood from the above description of the operation, according to the above embodiment, the roll body 13 in which the long film body 12 is wound in a roll shape is one surface that is exposed to the outside of the roll body 13. An adhesive portion 14 for attaching the film body 12 to the surface 12a is formed. For this reason, the roll body 13 can be adhered to the surface of the windshield 20 by the roll body 13 itself. Therefore, an operator who attaches the film body 12 to the surface of the windshield 20 rolls the roll body 13 in the state where the roll body 13 is attached to the surface of the windshield 20 in the direction of attaching the film body 12 with one hand. 12 can be pasted. In this case, since the roll body 13 is adhered to the surface of the windshield 20 by the adhesive portion 14 formed on the surface of the film body 12, the roll body 13 even if the operator removes the hand from the roll body 13. The position and posture of the camera will not shift unexpectedly. As a result, the film body 13 can be attached to the long windshield 13 in a good finished state easily and in a short time.

  Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention. In the following description of the modified example, the same reference numerals are given to the same components as those in the above-described embodiment in each of the referenced drawings, and the description thereof will be omitted.

  For example, in the above embodiment, the film body 12 is attached to the windshield 20 in order to prevent frost and ice from adhering to the windshield 20. However, the location where the film body 12 is pasted is appropriately determined according to the purpose of pasting the film body 12, and is naturally not limited to the above embodiment. Therefore, the film body 12 may be attached to a location other than the windshield 20 in the vehicle, for example, a side window, a rear glass, a roof glass, a side mirror, or a cargo bed, in order to prevent frost and ice from adhering. It can also be affixed to each part of the vehicle for purposes other than prevention of frost and ice adhesion, for example, masking for car body painting, prevention of damage such as scratches on the vehicle, and ensuring privacy in the vehicle.

  Moreover, in the said embodiment, the private vehicle was assumed as a sticking object of the film body 12. FIG. However, the film body 12 is attached to a vehicle other than a private automobile such as a vehicle other than a private automobile such as a buggy or a golf cart, a special vehicle such as a motorcycle, a bicycle, a tricycle, a power shovel, or a train. Can be pasted on the surface. In this case, by attaching the film body 12 to the surface of a motorcycle or bicycle seat or saddle, it is possible to easily remove a frozen portion such as frost or ice in the seating portion in a short time.

  Moreover, in the said embodiment, the adhesion part 14 was formed in the whole surface in the one surface 12a of the film body 12. FIG. However, the adhesive part 14 does not necessarily have to be formed on the entire surface of the film body 12 as long as the film body 12 can be attached to an adherend such as the windshield 20. That is, the adhesive portion 14 may be partially formed along the longitudinal direction of the film body 12 on the one surface 12 a of the film body 12.

  For example, as shown in FIG. 4, the adhesive portion 14 may be formed by applying an adhesive material in a lattice shape to one surface 12 a of the film body 12. Further, as shown in FIG. 5A, the adhesive portion 14 may be formed by applying an adhesive material in a plurality of lines along the longitudinal direction of the film body 12. In this case, as shown in FIG. 5 (B), the adhesive portions 14a and 14b may be provided on both end sides in the width direction of the film body 12, respectively. According to this, since an operator can avoid touching the adhesion part 14 by holding | griping the axial direction center part of the roll body 13, it becomes easy to perform the sticking operation | work of the film body 12. FIG. And according to these, compared with the case where the adhesion part 14 is formed in the whole surface of the film body 12, since the adhesive force of the film body 12 becomes small, it becomes easy to perform the sticking operation | work of the film body 12, and a peeling operation | work. Moreover, since the usage-amount of the adhesive material which comprises the adhesion part 14 decreases, the protective film 10 can be produced economically.

  The type of the adhesive material constituting the adhesive part 14 can also be applied to and removed from the adherent part, and the adhesive material is attached when the film body 12 is peeled off from the adherent part. If it does not remain in the part, it is not limited to the above embodiment. For example, you may comprise the adhesion part 14 using resin materials (for example, vinyl type, poly type) other than an acrylic type, or a rubber-type adhesive material. Moreover, if it exhibits the same function as an adhesive material, it can employ | adopt regardless of difference in names, such as an adhesive agent. For example, an adhesive tape can be formed by attaching an adhesive tape to the film body 12. Also by these, the same effect as the above embodiment can be expected.

  Moreover, in the said embodiment, the film body 12 was comprised transparently using the polyethylene material. However, the film body 12 is not limited to the above embodiment as long as the film body 12 has flexibility. That is, the film body 12 can be configured using a material other than the polyethylene material, for example, a vinyl chloride material, a polyester material, a cellophane material, a nylon material, a paper material, a cloth material, or the like.

  In these cases, the film body 12 may be formed to be translucent or opaque. According to this, in the state where the form body 12 is pasted, it is not possible to directly visually recognize the adhered portion to which the film body 12 is pasted or the inside of the deposited portion. For this reason, in the case where the film body 12 is attached to a window such as the windshield 20, privacy in the vehicle can be ensured. In this case, by constituting the color of the film body 12 with a black color that easily absorbs heat, it is possible to alleviate deterioration of components due to temperature rise in the vehicle and sunshine, and to the film body 12 with frost or ice. When it adheres, it can be naturally melted early by sunshine. Moreover, since it can recognize easily that the film body 12 has affixed, it can also prevent the film body 12 from forgetting to peel off.

  Moreover, in the said embodiment, the magnitude | size of the film body 12 was formed in thickness about 60 micrometers, width about 400 mm, and length about 15 m. However, the size and shape of the film body 12 are determined according to the size and shape of the adherend to which the film body 12 is attached, and are naturally not limited to the above-described embodiment.

  Moreover, in the said embodiment, it was made to cut | disconnect the film body 12 from the roll body 13 using cutting tools, such as a cutter. However, perforations, cuts, or creases may be formed in the film body 12 at predetermined intervals. For example, as shown in FIG. 6, a plurality of perforations 15 can be formed on the film body 12 at predetermined intervals along the axial direction of the roll body 13. According to these, the film body 12 can be cut | disconnected without using cutting tools, such as a cutter, and the workability | operativity and safety | security of the affixing operation | work of the film body 12 can be improved.

  Further, as shown in FIG. 7, perforations 15 are formed in the film body 12 at intervals corresponding to the size of the windshield 20, and along the edges of the film body 15 between the adjacent perforations 15. A frame-shaped adhesive part 14 can also be formed. According to this, since the film body 12 cut | disconnected for every perforation 15 respond | corresponds to the windshield 20 in the magnitude | size of the film body 12 and the formation position of the adhesion part 14, the film body 12 is efficient and effective. Can be pasted on.
