Description

[Detailed description of the invention] This invention relates to a sheet receiving member used as an element for holding vinyl sheets, etc. in vinyl houses, etc., and more specifically, it is capable of multiple sheet tensioning, and is compatible with conventional parts. The present invention relates to a sheet receiving member having a commonly applicable configuration.

(Background technology) Conventional general seat receiving members were
The one described in Publication No. 37715 is representative. As shown in Fig. 1, the left and right side walls 2, 2 following the bottom wall 1 are sloped walls that are symmetrically tilted inward.
It has a structure in which small round curled parts 3, 3 are formed at the upper end. The sheet 4 is elastically pressed and held in the groove of the sheet receiving member 11 by the locking line 5.

By the way, in a vinyl house or the like, simply being able to fasten one sheet 4 is not sufficient. For example, it is often necessary to double or triple the sheet 4 for the purpose of heat insulation and heat retention, or to layer cheesecloth for the purpose of blocking light.

However, the sheet receiving member 11 shown in FIG. 1 can only hold one sheet 4 with one locking line 5, and cannot meet the request for multiple tensions.

In this regard, in the seat receiving member described in Japanese Utility Model Publication No. 54-42350, as shown in FIG. to form a first dovetail groove, and then a second bottom wall portion 8 bent outward in a substantially horizontal direction;
8, and the following part forms a second inclined wall part 9, which is symmetrically tilted inward again to form a second dovetail groove, and the upper end is a small curled part 1.
0,10.

In other words, in the case of this sheet receiving member 12, the two dovetail grooves are formed in two stages in the depth direction, so the two sheets 4, 4' can be secured using the two locking lines 5, 5'. It is suitable for stopping the flow and serves the purpose of multiple tensioning.

However, the sheet receiving member 12 has the following drawbacks and problems.

That is, the frame of a vinyl house or the like is usually constructed of strong frame materials such as pipes, angles, and C-shaped steel, and the above-mentioned sheet receiving member 11 or 12 is placed on top of the frame.
It is attached and fixed using a special connecting tool and used for sheet tensioning.

For example, as shown in FIGS. 3A to 3C showing the relationship between the sheet receiving member 11 and the connector 13, the sheet receiving member 11 is inserted into the socket 14 of the connector 13 at an appropriate angle (FIG. 3A). , and then take a horizontal position within the socket 14 (Fig. 3). However, in reality, the connector 13 is operated to achieve the same result as before. After that, the connecting tool 13 is made to straddle the pipe 16, so that the bottom wall 1 of the sheet holding material 11 is brought into contact with the pipe 16. When this happens, the sheet receiving member 11 floats parallel to the inside of the socket 14, and
The latch claws 15, 15 formed at the entrance part of 4
is caught on the side walls 2,2. Therefore, when the wedge 17 is driven in, the pipe 16 and the sheet receiving member 11 are strongly pressed against each other, and are connected and fixed.

In other words, the connector 13 does not need to be passed from the end of the sheet receiving member 11 in the axial direction each time it is used, but can be attached to the sheet receiving member 11 from the lateral direction at any desired position.

However, in the case of the sheet receiving member 12 shown in FIG. 2, the height is particularly high due to the second dovetail groove, and the width dimension is also large. It is extremely inconvenient to use. The only way to eliminate this inconvenience is to develop and use a dedicated connector, which is extremely wasteful.

By the way, as shown in FIG.
The left and right side walls following 1 are formed into inclined wall portions 22, 22 whose lower portions are inclined inward in a substantially symmetrical manner,
The continuing middle part is a vertical wall part 2 that stands up almost vertically.
3, 23, and the upper portion is formed as a lip 24, 24 bent inward at a substantially right angle.
The outer width dimension of the vertical wall portions 23, 23 is the same as the outer width dimension of the curled portions 3, 3 in the sheet receiving member 11 shown in FIG. It is suppressed to a slightly higher level than 3. In the figure, 25 is a groove for positioning a screw.

Therefore, this sheet receiving member 20 can hold two sheets together using the two locking lines, and the connecting tool 13 used in the sheet receiving member 11 shown in FIG. 1 above can be used as is. can do.

However, when this sheet receiving member 20 was actually used, it was found that it had a drawback that the sheet was easily damaged when the sheet was pushed in and held by the strong spring locking line.

The reason for this is that the lip 24 is bent at a substantially right angle to form a flat surface, so when the sheet is forcibly pushed in with the highly springy locking line, the sheet is placed between the locking line and the lip. It is presumed that this is because the material is pinched and abraded with force.

(Purpose of the invention) Therefore, the purpose of this invention is to create a structure that allows for multiple sheet tensioning, common application of conventional parts, and a structure that does not cause damage to the sheet when it is stopped. An object of the present invention is to provide an improved seat receiving member.

(Means for Solving the Problems) As a means for solving the problems of the prior art described above, the seat receiving member according to the present invention has the following features in the cross section, as shown in the examples shown in FIG. The left and right side walls following the bottom wall 31 are inclined side walls 32 that are slanted inward in a substantially symmetrical manner with a width dimension determined for use of the connector 13, respectively.
32, and this inclined side wall 32 has a latch claw 15 provided at the mouth edge of the socket 14 of the connector 13,
Vertical side walls 33, 33 that rise approximately vertically upward from a position where the width becomes slightly narrower than the inner dimension of 15.
The vertical side walls 33, 33 can accommodate at least one locking line, and are formed at a height that does not hinder the insertion of the connector 13 into the socket 14, and the upper end thereof has an inner wall. A cylindrical curl portion 34 that bulges out.
It is characterized by the formation of

(Function) At least two locking lines 5 can be pushed into the inner pocket from the inclined side wall 32 to the vertical side wall 33, so that the same number of sheets as the locking lines can be stacked and stopped, The purpose of multiple tensioning is achieved. The locking line 5 is caught on the curled portion 34 and is prevented from coming off.

This sheet receiving member fits snugly into the socket 14 of the connector 13 used in the conventional sheet receiving member 11 (FIG. 1), and the same connector 13 can be used as is.

Since the curl portion 34 is formed in a cylindrical shape,
Since the sheet is easily held down by the locking line and there is little resistance, there is no risk of damaging the sheet during pushing.

Next, the embodiment shown in FIG. 5 and subsequent figures will be described.

(First embodiment) The sheet receiving member 30 shown in FIGS. 5A and 5B is
The left and right side walls following the bottom wall 31 are formed as follows.

That is, the lower part has an outer radius from the bottom wall 31.
Curved with a relatively large arc of R3.5, and
They are formed in inclined wall portions 32, 32 that are symmetrically inclined inward.

The intermediate portion following the inclined wall portion 32 is formed as vertical wall portions 33, 33 that stand vertically in parallel to the left and right.

The upper portion of the vertical wall portion 33 is formed as curled portions 34, 34 that have a substantially cylindrical shape with a relatively large radius and bulge roundly inside the vertical wall portion 33.

In the figure, reference numeral 35 denotes a groove provided for the purpose of positioning the tip of a screw when screwing the sheet receiving member 30 to an angle or the like that is a frame member of a vinyl house or the like.

This sheet receiving member 30 is formed by cold roll bending of a galvanized iron plate.

In FIG. 5A, the sheet receiving member 11 shown in FIG. 1 is shown as a double copy with dotted lines, and the shape of the sheet receiving member 30 from the bottom wall to the inclined wall portion 31 is , is the same as the sheet receiving member 11 shown in FIG. And the vertical wall portion 33
is equal to the outer width dimension of the curled portion 3 in the sheet receiving member 11 shown in FIG. 1, and although the height of the curled portion 33 is about 2 mm higher, the inner width dimension is the same.

Therefore, the sheet can be stopped by applying the locking line 5 shown in FIG. 1 as is. That is, one locking line 5 is used in the inner part of the inclined wall part 32, and one locking line 5' is also used in the inner part of the vertical wall part 33 at a position below the curl part 34. then 2
It is possible to hold two sheets 4, 4', and the purpose of multiple tensioning can be easily achieved (FIG. 6B).

Furthermore, when the sheet is pushed in and stopped by the locking line 5 or 5', since the entrance portion is rounded by the curled portion 34, it slides in without much resistance. Therefore, there is no risk of damaging the sheet by rubbing it strongly.

Moreover, since this sheet receiving member 30 has the above-described shape and size, as shown in FIGS. 6A and 6B, the connector 13 applied to the sheet receiving member 11 of FIG. 1 can be used as is, and , Figure 3 A, B
It can be attached and fixed to the pipe 17, which is a frame material of a vinyl house, etc., in exactly the same manner as shown in FIG.

(Other Examples) The sheet receiving member shown in FIG.
3 is tilted outward at a slight angle.

In the sheet receiving member shown in FIG. 8, the inclined wall portion is configured as an arcuate wall portion 40 having a substantially semicircular shape.

In the sheet receiving member shown in FIG. 9, the inclined wall portion is configured as a substantially rectangular corner wall portion 41.

The sheet receiving member shown in FIG. 10 has a step portion 41 that is bent inwardly into a small arc at a portion where the inclined wall portion 32 changes to the vertical wall portion 33.

The sheet receiving member shown in FIG. 11 has a structure in which the curled portion 34 is bent outward.

(Effects of the present invention) As detailed above, the sheet receiving member of the present invention is capable of stacking and fastening two or more sheets using at least two locking lines, and is capable of holding multiple sheets together. The purpose is achieved and contributes to the multifunctionality of vinyl houses.

In addition, the conventional sheet receiving member 11 shown in FIG.
The structure is convenient and economical because the connector 13 and other parts used in the present invention can be used as they are.

Furthermore, since the entrance of the sheet receiving groove is formed round by the cylindrical curled portion 34, the sheet can be easily held down by the locking line, and the sheet can be easily pushed in with little resistance. There is no risk of damage, and it contributes to the construction of high-quality vinyl houses.
