Abstract

<P>PROBLEM TO BE SOLVED: To eliminate unevenness in the tension of a net, and obtain favorable finished quality of a window screen. <P>SOLUTION: Special equipment 1 is attached to a screening surface tensioning roller 8, and is used for screening surface tensioning of the window screen as appropriate. Then screening surface tensioning of a first frame side and a second frame side is performed by using the screening surface tensioning roller without the special equipment 1 while paying attention to parallelism between the frame sides and the mesh of the screen. Then screening surface tensioning of third and fourth frame sides is performed by using the screening surface tensioning roller with the special equipment 1. Then the general outline of screening surface tensioning is that when the screening surface tensioning roller 8 presses the screen and a screen-pressing beat into a frame groove simultaneously, the wheel 4 of the special equipment presses the screen, which is in the left-slanting front of the wheel 11 of the screening surface tensioning roller 8, against the frame side which is below the wheel 4. Then pressing the screen produces the same effect as the work of pressing and spreading the screen toward the outside of the window screen frame with one hand does, and the tension of the screen is made more uniform, thus the finished condition of the window screen is considerably improved. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

  The present invention relates to a tool used to screen a screen door.

  A conventional general screen method for screen doors will be described below. First, the screen of the screen door is screened sequentially on the four frame sides constituting the screen door frame, but the frame side and the mesh of the first frame side and the second frame side are approximately parallel to the frame groove. Push the net and the mesh holding beat at the same time, and stretch the net out of the screen door frame with the other hand as many times as necessary on the third and fourth frame sides. Push the net and the net holding beat into the frame groove with the roller at the same time. Next, look around the screen door and correct any blisters or wrinkles, and then align the ends of the screen retainer beat in the frame groove. Finally, the net is beaten to remove excess nets.

Problems to be solved by the invention

  While pushing the net out of the screen door with one hand as many times as necessary on each of the third frame side and the fourth frame side mentioned above, the net and net presser in the frame groove with the netting roller of the other hand In the work of pushing the beats at the same time, non-uniform tension often appears on the net due to the strength of the net that pushes the net out of the screen door frame (this non-uniform tension is caused by touching the net directly by hand). Can be detected reliably). And the uneven tension of the net leads to the blistering and wrinkling of the net, and this has the problem that the finish of the screen door is hindered.

Means for solving the problem

  In order to solve the above problem, the above-described operation of pushing the net out of the screen door frame with one hand is replaced with a special tool attached to the netting roller. This special tool basically consists of a mesh holding part (the part that presses the net against the frame side) and a mesh holding part support part (the part that holds the mesh holding part in a fixed position from the netting roller), The former net retainer is equipped with a car (this car is hereinafter referred to as a special equipment car). The netting roller with this special tool is used for netting the 3rd frame side and the 4th frame side as a basic rule when netting the 4 frame sides of the screen door frame sequentially. Hereinafter, the operation of the special tool will be described by taking as an example the case where the four frame sides of the screen door frame are sequentially meshed clockwise. First, in order to effectively obtain the function of the special tool, the first frame side and the second frame side are arranged in parallel with the frame side and the mesh of the net, and the netting roller without the special tool is attached. Use netting. With this as a premise, the screen shifts to a net of the next third frame side and the fourth frame side. The important point in the netting of each of the third frame side and the fourth frame side is that when the netting roller pushes the net and the net holding beat simultaneously into the frame groove, the special equipment car also It is to press the net on the left side of the tension roller car against the frame side (this left front is clearly shown in FIG. 2. This figure is for the purpose of showing the position on the left front. In the figure, the net and the net holding beat are omitted, and only the main outline of the vehicle in operation is depicted.The reference numerals in the figure are those of the embodiments described later for the sake of convenience. Indicates the frame side, and the arrows in the figure indicate the traveling direction of the car.) This pressing of the net prevents the net from being pulled into the frame groove by the netting roller, resulting in the same effect as the conventional work (work of pushing the net out of the screen door frame with one hand). be able to. In addition, the net tension becomes even more uniform.

Next, each part of the special tool is listed.
First, the special tool is not particularly limited in terms of the component structure or the like as long as its function is ensured, and is preferably composed of, for example, a net presser and a net presser support.

  Subsequently, the special tool may be freely attached to the left side and the right side of the netting roller according to the dominant arm of the operator. FIG. 2 shows the special tool attached to the left side of the netting roller.

  Subsequently, the shape and the like of the mesh pressing portion of the special tool is not particularly limited as long as it has a function of pressing the net against the frame side. For example, an elastic material (spring or the like) that functions to press the special tool car against the frame side. ) May be attached.

  Subsequently, the special purpose vehicle works to press the net directly against the frame side in order to prevent the net from being pulled into the frame groove by the netting roller, but if this function can be secured, The distance A between the centers of the two cars in FIG. 2 and the opening width B of the two cars are not particularly limited. For example, the distance A between the centers is preferably about 25 mm, and the opening width B is preferably about 17 mm.

  In addition, special-purpose vehicles are basically moved with a net-roller roller vehicle in a state of standing almost perpendicularly to the frame side when netting. The tool car does not have to be in a state of standing substantially vertically as described above.

  The special-purpose vehicle is not particularly limited in terms of form and the like as long as it has a function of pressing the net directly against the frame side, and may be, for example, a rubber tire.

  Subsequently, the shape of the screen holding portion supporting portion of the special tool is not particularly limited as long as it has a function of holding the screen pressing portion at a certain position from the screen-rolling roller. It may be attached to a netting roller.

  Subsequently, the special equipment car of the netting roller with special equipment may be in the following two states when the net door is netted. One is the state where the net is pressed against the frame side, and the other is the state where the net is not pressed against the frame side. As a specific example, a portion attached to a netting roller of a special tool may be a movable part such as a hinge. With such a structure, when the four frame sides are sequentially meshed, the special tools can be flipped up to use only the mesh roller in the first and second frame sides. In the netting of the 4th and 4th frame sides, the special tool can be lowered and used as a netting roller with the original special tool.

  Subsequently, the method of attaching the special tool to the netting roller is not particularly limited as long as the function of the special tool can be exhibited. For example, the special tool is located on the right side or the left side of the netting roller. The body of the net holding part support part and the netting roller may be integrally formed.

  Subsequently, when using a netting roller with a special tool, make sure that the car of the special tool presses the net against the frame side. In order to use the special tool, it is important to press the net securely.

  Subsequently, the special tool has a function of uniforming the screen when the screen doors are screened. The special tool is not used in the netting of the frame side and the fourth frame side.

  Subsequently, the special tool is basically used by being attached to a netting roller. The netting roller is not particularly limited as long as it draws out the functions of the special tool. However, netting rollers that cannot be used due to circumstances are excluded.

  The special tool portion and the like have been described above. In the description of the present invention, the meshing of the four frame sides of the screen door frame is clockwise, but in the case of counterclockwise rotation, this clockwise description will be applied mutatis mutandis.

Embodiments of the present invention will be described below with reference to the drawings based on the embodiments.
First, in this embodiment, a netting roller with a special tool shown in FIG. 1 is used. In the present embodiment, a netting roller without the special tool (a netting roller without the special tool is hereinafter referred to as a netting roller S) is also used. The usage of both of these is that when the four frame sides of the screen door frame are sequentially screened, the netting roller S is used to screen the first frame side and the second frame side, and the third frame side and the second frame side are used. Use a netting roller with special tools in the 4th frame. Now, the special tool 1 is composed of two parts, a net presser 2 and a net presser support 3, which will be described next. First, the mesh retainer 2 has a function of pressing the mesh 12 against the side of the frame. The mesh retainer 2 includes a special vehicle 4, a special vehicle mounting portion 5, a special vehicle spring 6, It consists of each part of a special mandrel 7 for vehicles. Next, the mesh presser support part 3 is a part that holds the mesh presser part 2 at a fixed position from the netting roller 8, but two mandrels 7 of the mesh presser part 2 are passed through the mesh presser support part 3. There is a hole. The mesh presser support 3 is attached to the mesh roller 8 with two bolts and nuts (only one bolt and nut appear in the figure). The screen retainer support 3 is attached to the left side of the screen roller 8 and is a screen roller with a special tool for clockwise rotation of the screen.

  An example of screen netting of a screen door using both the netting roller with special tools and the netting roller S described above will be sequentially described. First, as a preparation before netting, the net 12 is covered over the entire screen door frame so that the frame side and the net of the net 12 are parallel. As a definition of the terminology, the netting start portion where the net 12 and the net holding beat 13 are pushed into the frame groove 16 at each frame side of the screen door frame is referred to as a netting start point 14, and the netting end portion of the same frame side is followed. Is called the netting end point 15 (see FIG. 3).

Based on the above preparation, the netting of the first frame side will be described with reference to FIG.
First, using a mesh roller in an L shape from the mesh end point 15 of the frame groove 16 on the fourth frame side to the mesh start point 14 of the frame groove 16 on the first frame side, the mesh 12 Push in the net holding beat 13. Then, the net 12 around the intersection of the net end point 15 of the first frame side and the net start point 14 of the second frame side is netted from the net start point 14 of the first frame side. The straight line is pushed in the direction of the end point 15. At this time, attention should be paid so that the first frame side and the mesh of the mesh 12 are substantially parallel. Then, the net 12 and the net pressing beat 13 are simultaneously pushed into the frame groove 16 on the first frame side using the netting roller S in a state where the net 12 is stretched.

Next, the netting of the second frame side will be described with reference to FIG.
First, the net 12 and the net holding beat 13 are pushed into the net starting point 14 on the second frame side by about 3 cm in length. The subsequent work procedure is the same as the above-described netting procedure for the first frame side.

Next, the netting of the third frame side will be described with reference to FIG.
First, the net 12 and the net holding beat 13 are pushed into the net starting point 14 on the third frame side by about 1 to 1.5 cm in length. Then, the net 12 around the intersection of the third frame side and the fourth frame side is pulled in the direction of the arrow. Then, in this pulled state, the net 12 and the net holding beat 13 are pushed into the net starting point 14 on the fourth frame side by about 3 cm. Then, holding the netting roller with a special tool on the right hand, the net 12 and the net pressing beat 13 are simultaneously pushed into the frame groove 16 on the third frame side. After the netting, the net 12 and the net pressing beat 13 that are pushed into the netting start point 14 on the fourth frame side are removed from the netting start point 14. The points to be noted about the netting of this frame are that the left hand may be attached to the right hand with a netting roller with special equipment when netting, but it should be avoided to touch the net 12 in the netting as much as possible. The tool wheel 4 is to press the net 12 on the left side of the car 11 of the netting roller 8 firmly against the frame side. In addition, if the netting roller with special tools is slightly moved back and forth, the netting can be done reliably and easily.

Next, the netting of the fourth frame side will be described with reference to FIG.
First, the net 12 and the net holding beat 13 are pushed into the netting start point 14 on the fourth frame side by about 3 cm in length. Then, the net 12 and the net presser beat 13 are simultaneously pushed to the net end point 15 on the same frame side using a netting roller with a special tool.

  After the above operation, the net press beat 13 is cut at the place where the net press beats 13 of the netting end point 15 on the fourth frame side meet each other. Then, look around the screen door and take appropriate measures if there is a defect. Then, the end of the mesh press beat 13 is pushed into the frame groove 16 so that the end of the mesh press beat 13 matches the end. Finally, the net 12 that has been pushed into the frame groove 16 on the four frame sides together with the net pressing beat 13 is cut by a cutter along the net pressing beat 13, thereby removing the residue of the derived net 12.

Next, the matters relating to the netting of the screen door using the special tool of the present invention described so far will be listed.
First, when the car 11 of the netting roller 8 is inserted into the frame groove 16, if the thickness of the car 11 of the netting roller 8 is not appropriate for the upper opening width of the frame groove 16, the function of the special tool is obstructed. Leads to. Therefore, the thickness of the car 11 of the netting roller 8 is selected appropriately in consideration of the thickness of the net 12 and the like.

  Subsequently, since the diameter of the mesh holding beat 13 with respect to the frame groove 16 also has a significant effect on the netting of the screen door, the diameter of the mesh holding beat 13 is appropriate for the frame groove 16 in consideration of the thickness of the mesh 12 and the like. Make things.

  Subsequently, nothing is placed in the screen door frame that pushes up the screen 12 until the screen work for the screen door is completed. Also, do not place an object on the net 12 until the netting work of the screen door is completed.

  Subsequently, in the case where the third frame side and the fourth frame side are netted, if the length of the framed side is 1.5 m or 1.8 m, etc. If the net 12 is stretched out of the screen door frame with the left hand around the middle part of the side and stretched out, the uniform net 12 can be more reliably obtained.

The invention's effect

  Since the present invention is configured and used as described above, the following effects can be obtained.

  First, when netting the four frame sides sequentially, the force to push the net out of the screen door frame if a netting roller with this special tool is used on the third frame side and the fourth frame side netting Easy and easy netting without worrying about strength.

  In addition, in the netting of the third frame side and the fourth frame side when performing the netting of the four frame sides in sequence, the work of pushing the net out of the screen door frame with one hand is often uneven. (Unevenness) appears, but in the netting operation using the netting roller with the special tool, the unevenness is extremely reduced and the netting becomes uniform. By using the netting roller with the special tool in this way, uniform netting is obtained, which leads to blistering of the net and drastic reduction of wrinkles. Therefore, the finished state of the screen door is remarkably improved.
