Description

  In this invention, a sheet fixing wire is inserted into a groove of a sheet fixing groove shape material fixed to a frame material such as a greenhouse, a door frame, a window frame or the like, a vinyl chloride sheet or a polyolefin sheet, which is a covering material of a greenhouse, etc. (Hereinafter simply referred to as a sheet) and belongs to the technical field of a sheet fastening tool used for the work of pushing the sheet into a groove and fastening the sheet.

  Conventionally, a sheet, which is a so-called greenhouse covering material for forcing cultivation of various vegetables and fruits, is fastened by a sheet fastening groove shape attached to a frame material. As illustrated in FIG. 8A, the sheet retaining wire to be used is an elastic trapezoidal wave that continues in the direction in which the same trapezoidal wave is alternately inverted with an amplitude slightly larger than the opening of the sheet securing groove member 4. This is a sheet retaining wire 2 'having a shape. To fix the sheet, the sheet is spread over the opening of the sheet fixing groove of the sheet fixing groove shape, and one end of the sheet fixing wire is first pushed into the sheet fixing groove together with the sheet from the top. Thereafter, the free portion remaining outside the groove of the sheet fixing wire is sequentially pushed into the sheet fixing groove in units of each waveform. A sheet fastening tool has been proposed in order to mechanize the seat fastening work and to proceed efficiently and easily.

For example, the sheet fastening tool disclosed in Patent Document 1 below includes a sliding portion that slides in the longitudinal direction on the opening edge of the sheet fastening groove member, and a manual operation portion that is raised upward from the sliding portion; The sliding guide portion is provided so as to project from the lower surface of the sliding portion, and the wire rod guide member is provided with a planar shape in a substantially C shape at the front end of the sliding portion. The sheet fixing tool is used by pushing the edge of the sheet fixing wire together with the sheet into the sheet fixing groove of the sheet fixing groove shape, and then moving the sliding part to both edges of the sheet fixing groove shape. The manual operation unit is pushed onto the sheet and the sheet fixing tool is advanced forward in the longitudinal direction of the sheet fixing groove material. Then, one mountain and one mountain of the sheet fastening wire collide with the left and right wire guide members one after another, and the sheet fastening wire is guided into the sheet fastening groove and fixed in the sheet fastening groove.
However, the sheet fixing tool has a strong resistance (rigidity) of the trapezoidal wave-shaped sheet fixing wire, and the trapezoidal wave-shaped sheet fixing wire has a sheet fixing groove shape as shown in FIG. When guided into the groove of the material, it may swing greatly to the left and right, and the sheet fastening wire may be disturbed by the left and right swing, and the fastening operation may not be performed smoothly and efficiently.

  Therefore, in Patent Document 2 below, the sheet fixing groove shape is attached to the front end portion of a mounting rod having a considerable length arranged in parallel with the sheet fixing groove shape mounted rotatably on the main body. There is disclosed a sheet fastening tool having a configuration in which a fastening line guide combined with an appropriate interval for passing a sheet fastening wire through two guide plates parallel to the opening edge of the sheet fastening groove is attached. This sheet fastening tool pushes an elastic trapezoidal wave shaped sheet fastening wire into a sheet fastening groove and fastens the same sheet in the direction that the same trapezoidal waves are alternately reversed. Thus, the two guide plates suppress the lateral swing width of the sheet retaining wire as much as possible and guide it smoothly and regularly, and are not disturbed by the lateral motion of the sheet retaining wire.

  In addition, the sheet fastening tool disclosed in the following Patent Document 3 is a trapezoidal shape between the plate materials by laminating the plate materials with an interval attached to the arm attached to the front end surface of the sheet fastening tool main body and inclining both sides broadly. It is the structure which provided the stop line guide so that a corrugated sheet | seat stop wire may pass.

The sheet fastening tools disclosed in Patent Documents 2 and 3 have a linearity of 2.0 mm and a high spring property, and the same trapezoidal wave on one plane has a pitch of about 120 mm and an amplitude of about 35 mm alternately. Since the trapezoidal wave-shaped sheet retaining wire connected in the direction of reversing the direction is pushed into the sheet fastening groove shape, the resistance (rigidity) to pushing into the groove of the sheet fastening groove shape is large, As shown in FIG. 8 (B), it swings greatly from side to side, so that the stop line guide suppresses left and right side swings and overcomes the resistance action due to the strong rigidity and springiness of the sheet stop wire, and is pushed into the groove. It has the structure, function and mechanism for achieving the purpose of fastening. Therefore, the number of necessary members is large, and each component is assembled into a complicated shape, and a complex structure is formed by combining them.
Further, since the stop line guide is not positioned on the sheet fixing groove shape, there is a problem that the sheet fixing tool floats when the sheet fixing tool body is run. Therefore, the seat fixing tool main body becomes unstable, and the fixing operation may be performed smoothly and efficiently.
