Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of joining and easily laying a seam portion via a fastener or the like, and a laying device used in the method.

In recent years, with the development of various sports, field structures made of artificial turf that can maintain a certain level of conditions have become increasingly popular. Although it is possible to manufacture long mats such as artificial lawns and carpets on their own with a wide area, they are generally made into multiple pieces due to handling issues such as transportation and installation. Divided rugs are often joined together at all sites. Various methods are used to join the rugs together. Also, methods are used to join the joints of the rug from the back side with narrow tape or to sew them together. However, with these methods, the joints are fixed, resulting in a large area of integrated rugs,
The rug itself becomes a ground or floor surface with a fixed surface layer, and the surface layer material is required to have multipurpose functions.
In order to meet this requirement, there is a problem in that an expensive surface material must be used, and there is also the drawback that re-covering, restoring, etc. require a lot of time and effort.The present invention solves all of the above-mentioned drawbacks. It was carefully devised,
The purpose is to provide a method for laying rugs, etc. that can easily repeat the joining, splicing, and dividing work of rugs at the construction site and has excellent work efficiency, as well as a laying device that can be used directly for the method. be. That is, either the female part or the male part of a zipper, etc. is attached to the backing material of each side edge of a large number of rugs in advance, and one end of the contacting side edge of the rug is machined and then the other end is reciprocated. Contact 4 (!I) While opening the edges one by one, move the laying device that has a guide cover at the tip to raise it above the entire floor surface of the part, and place it on the backing material of the side edge attached to the laying device.・Feed out the fastener tape that was made to engage with the girder fastener while unraveling it, and feed it out in the opposite direction to the moving direction of the laying device so that the contact edges of the mutual side edges of the rugs are Place the tape on the floor so that it is approximately at the center of the tape, and after passing through the guide cover installed at the tip of the laying device, the backing material is lifted up and the zippered edges on both sides are in contact with the floor. This is a method of laying rugs, etc. in which the fasteners are bonded to the top tape and moved over the bonded rug while pressing a pressure roller to further secure the bonded fasteners. The embodiment shown in the drawings will be described.

Reference numeral 8' denotes a bracket fixed near the substantially middle portion of the pair of vehicle body frames 1, 1', and the pressure roller 1 is attached to the bracket.

One end of the spread-leg roller support rod that supports the is pivotally connected to the
The pressure roller 10 is rotatably mounted on the other end of the spread roller support rods 9, 9'. In the embodiment shown in FIGS. 1 and 2, the support rods 9, 9' for the leg rollers 4 are pivotally connected to the pair of body frames 1, 1' via brackets 8.8'. The leg roller support rod can also be mounted directly on the body frame 1.1'. In this embodiment, each of the leg roller support rods 9 and 9' is hook-shaped (!-shaped), but they are formed considerably wider than the pressure roller ioFi fastener tape 7 and the vehicle body A. Therefore, one end of the regulating member 11 and 11' for restricting the rotation of the leg roller support rods 9 and 9' is connected to the pair of LIL body frames, as long as the structure is necessary to support this. The support rod 9 is pivotally attached to the lower part of the middle part of the rods 1 and 1', and the other end is the support rod 9.

It is removable at 9'. A portion of the regulating member 11° 11' may be a spring or the like having strong elasticity to impart elasticity to the pressure roller 10.

Further, the rug is configured with a streamlined curve extending rearward and upward from the tip, and widens toward the rear on both sides from the tip, so that the contact side edge of the rug is opened by the tip, and the contact side edge of the rug is opened by the tip, and A guide cover B' is arranged to straddle the tip of the vehicle body A and is configured to raise the contact side edge of the rug above the floor surface by spreading to the guide cover B'. 12 is a guide roller pivoted inside the tip of the guide cover B, and 13 and 13' are stays disposed facing outward near the tips of the vehicle body frames 1 and 1', and the stay allows the guide cover to be B' engages and straddles the main body A.

Reference numeral 14 denotes a handle that fully rotates the original fabric support shaft 5 when rewinding the tape, which will be described later.Normally, it is connected to a spacing retainer 15 installed near the rear end of the vehicle body frames 1, 1'. It's a dress.

FIG. 3 is a perspective view of another embodiment of the rug laying device of the present invention, in which the same parts as in the first embodiment are designated by the same reference numerals, and detailed explanations are omitted. However, in this embodiment, the spread-leg roller support rod 9
．． 9' is widened towards the end when viewed from above, and has a streamlined curve extending backward and upward from the tip of the guide cover B, which straddles the tip of the vehicle body A. In particular, the center part has a ripple shape so that the contact side edge of the rug is It has a structure that makes it easy to open.

The shape of the guide cover B is selected depending on the amount of M of the rug itself and the slipperiness of the back surface.

The rug laying device of the present invention is as described above, and its use will be explained with reference to the drawings along with the rug laying method.The joining member used in the present invention may be a pressure bonding tape. For example, the tape may be a tape that pressure-bonds a pair of a male member made of thread with an enlarged head and a cut loop at the end, and a female member that fits into the male member. The structure and type may be of any type, including a backing material 17Vc for the side edge 16' of the rug 16 to be joined; Adhesive is applied to the fastener tape 7' (male part and/or female part) continuously or intermittently along the front and rear side edges 16' in advance.
Attach by sewing or other appropriate method. In this way, a large number of rugs 16 are prepared with the backing material 17Vc fastener 7' attached to the side edge 16', and the required laying area is set so that there is no gap between the joint parts of the rugs 16, that is, the contact side edges 16'. After placing the mat on the area, the contacting side edges 16' of the rugs are successively opened from one end of the mutual contacting side edges 16' to the other end using the tip of the guide cover B provided at the tip of the main body A of the laying device. While doing so, the laying device is advanced so that the part is raised above the floor surface. The guide cover B, which is installed over the tip of the main body A of the laying device, has a streamlined tip pointing upward and backward, and the width becomes wider from the tip of the hook toward the rear on both sides. It is possible to smoothly open all the mutually contacting side edges of the rug 16 at the tip of the guide cover B and to lift the part off the floor on both sides of the guide cover B, and moreover, it can be done sequentially. It is also something that can be done easily.

In this way, the laying device is moved with the contact side edge 16' of the rug 16 separated from the floor surface. The fastener 7, which is designed to engage with the fastener 7' attached to the backing material 11 of
It is reversed and fed out via the unraveling roller 6 that is loosely fitted into the
The contact edges of the mutual side edges of the rug are connected to the feed-out tape 7.
The tape 7 is placed on the floor surface on the opposite side to the direction of movement of the laying device so that it is approximately at the center of the tape 7. Then, when the guide cover B installed over the tip of the main body A of the laying device passes, the contact side edge of the rug 16 is released from the floating state and returns to the original contact state, so that the main body of the laying device When placed on the tape 7 placed on the floor surface by A, the fastener 7' attached to the backing 17 of the side edge 16' of the rug 16 and the tape 7 placed on the floor surface are joined. , the tape 7 is joined across the side edges 16' and 16'' that are in contact with each other (see Fig. 6), and the contact state of the rug can be reliably maintained. Accordingly, the pressure roller 1o of the laying device does not pass over the top of the Afc mat in the bonded state.
The fastener in the bonded state is more firmly attached by a pressing force of 0.

Regarding the dividing operation, after removing part of the zipper from each rug, the remaining zipper tape can be easily removed by fitting the handle 14 onto the original fabric support shaft 5 and unwinding it. It is something that can be recovered. Further, the laying device of the present invention can be automated using a small power source.

As described above, the laying device used in the present invention consists of the main body A, the guide cover B, and the pressure roller, and has a simple structure with a small number of parts, so it is easy to handle, which was previously considered difficult. The use of pressure bonding members such as fasteners makes it easy to lay rugs and to join and disassemble mutually contacting edges, making it possible to temporarily install rugs both indoors and outdoors, regardless of the size of the laying area. It can be used and its effects are great.
