Description

  The present invention relates to a wire guide used when, for example, a wire that stretches a perennial plant is stretched.

The pergola 1 (FIG. 1) is basically composed of four columns 2 (2a-2b) and two columns (2a-2b, 2c-2d) arranged at the front and rear and the left and right. 3 (3a, 3b) and a number of rafters 4 installed between the left and right girders 3. From a structural point of view, it can be said to be a gate-shaped structure having a U-shaped cross section composed of a left side surface portion A, a ceiling surface portion B and a right side surface portion C.
When greening such a pergola 1, the ceiling surface portion B is often covered with a wire mesh and tangled plants are entangled with the wire mesh. However, since the mesh of the wire mesh is narrow, a feeling of pressure is felt when entering the pergola 1. Also, the wire mesh requires time and labor for laying and removing.
Therefore, a greening structure has been proposed in which wires 5 are stretched in the vertical direction and the horizontal direction on the pergola 1 so that vine plants grow along the wires 5.

At this time, in the pergola 1 as shown in FIG. 1, the horizontal members 6 are laid in parallel to the girders 3 on the upper and left sides of the rafter 4, and the wires 5 are stretched through the horizontal members 6. For this reason, when the wire 5 is stretched from the left side surface A to the left side surface C via the ceiling surface portion B in the pergola 1, bent portions D of the wire path are generated on both sides of the ceiling surface portion B (in FIG. Only the book is shown).
In addition, such a bent part D does not use the horizontal member 6, and the wire 5 has a side surface (such as the left surface A) and a ceiling surface (such as the ceiling surface B) having a different angle with respect to the side surface. This also occurs when the wire is stretched on an object to be stretched (pergola, facade, parking lot, terrace with roof, balcony, etc.). The side surface portion is not limited to vertical, and the ceiling surface portion is not limited to horizontal.

At this time, if the wire is wound around with one wire, the wire 5 comes into contact with the horizontal member 6 at the bent portion D, and the horizontal member 6 and the wire 5 are damaged. Further, a large force is required to pull the wire 5 due to friction at the contact location.
The above problem can be solved by placing a cushion material or a sliding material at the contact point with the horizontal member 6, but one end of the wire 5 is fixed to the ground or the like and the left side surface A through the ceiling surface portion B. When it is necessary to draw and fix in the tension state at the lower part of the right side surface part C, the wire 5 is loosened as soon as the operator loosens his hand, so the respective parts of the left side surface part A, the ceiling surface part B and the right side surface part C are Difficult to maintain evenly and strongly tensed.
For this reason, when the scale of the pergola 1 is large, an operator is added to the ceiling surface portion B, and the two-person operation is performed while maintaining the tension of the left side surface portion A and the tension of the ceiling surface portion B sequentially.

Furthermore, the fasteners 7 are attached to the left and right ends of the upper surface of the horizontal member 6 (FIG. 2), and the horizontal wires 5 are stretched between the fasteners 7b on both sides, while the eye bolts 8 are attached outward from the fasteners 7. The wire 5 in the vertical direction may be stretched through a wire grip 10 between the eyebolt 9 and the other eyebolt 9 that is fixed by overhanging.
If it does in this way, since neither the wire 5 of a horizontal direction nor the vertical direction will contact the horizontal member 6, these will not be damaged.
However, in this structure, it is necessary to fix a large number of fasteners 7 to the horizontal member 6 by welding or the like, and holes or eye bolts 8 for engaging the hooks on the wire side are also provided on the fasteners 7 themselves. Must be processed. The number of the fasteners 7 is considerable when the horizontal member 6 is long and the pitch of the wire arrangement is small.

Furthermore, a plurality of wires 5 are required, and hooks are provided at both ends of each wire 5, so that the number of parts increases and labor is required in addition to stretching the wires 5.
Above all, in such a structure, the position of the fastener 7 is fixed, and the pitch and direction of the wire 5 cannot be adjusted and tensioned according to the situation at the site.

The above-mentioned problems are not limited to the case where a wire is hung around a pergola, but generally occurs in a wire stretching operation in which a bent portion is present in the route of the hung wire.
In this device, even if there is a bent portion in the wire path, there is no damage to the wire and the object to be stretched (in the above case, the pergola horizontal member), and the wire that is continued through the bent portion The issue is to provide a wire guide that can be tensioned by one person.

Provided is a wire guide having the following configuration used at a bent portion of a wire path.
Basically, it includes a case, a grooved pulley and a stopper.
The case has a groove shape that is long in the front-rear direction and has a bottom wall and left and right side walls.
A pair of grooved pulleys are arranged in the case with an interval in the front-rear direction.
Each pulley is rotatably supported by a respective shaft installed between the side walls.
The stopper has a U-shape consisting of left and right leg pieces and a connecting piece connecting these tips.
The stopper is pivotally supported by the lower part of each leg piece on the side wall of the case so that it can be rotated with difficulty of finger operation.
The leg piece of the stopper has a length that allows the connecting piece to turn around the lower surface side of the case beyond the front end or the rear end of the case.
“Difficult to perform finger operation” means that there is a strong resistance to the operation of turning the finger against the stopper to rotate it with respect to the case, and it is difficult to rotate by the bending restoring force of the wire. .

Corresponding to each of the pulleys, there may be a structure in which a wire holding rod is installed between the side walls with an interval through which the wire can be inserted above the pulley.
The wire guide may be a wire tension member that is combined with a mounting aid for mounting the wire guide on another member.
The mounting aid may be a detachable tool for attaching and detaching the wire guide to and from the rail. Further, the rail may have a guide slit along the longitudinal direction, and the attachment / detachment tool may be structured to be movable and positioned along the guide slit.
In either case, the attachment / detachment tool has an axis perpendicular to the rail surface, and may have a structure in which the wire guide is rotatably attached to the rail.
Further, the mounting aid may be a clamp and a shaft member rotatably attached to the wire guide with respect to the clamp.

The wire does not contact the object to be stretched at the bent portion of the wire path.
The stopper can be used to temporarily maintain the tension of the wire at the bent part of the wire, so that the whole wire can be tensioned while maintaining a continuous tension state for each bent part. Work becomes possible.
The wire stretching interval (pitch) is not limited.
By using the wire extension member in combination with the mounting aid, it can be used in a wide range regardless of the shape of the attachment location. Moreover, the path | route which extends a wire can be set to arbitrary angles.

Since two grooved pulleys are arranged at the front and rear, the direction of the wire passing through the wire guide is determined and the tensioned state is stabilized.
When the direction in which the wire is pulled is set to the front, the front pulley receives a force in the direction of pressing the case downward around the rear pulley, so that the posture of the entire wire guide is stabilized.
Since there is a gap between the front and rear pulleys, the rear pulley can be arranged to protrude rearward from the edge of the object to be stretched, and the contact between the wire and the object to be stretched can be reliably prevented.

A thing provided with a wire holding rod can prevent the situation where a wire comes off from a wire guide at the time of the start of tension work.
In the case where a wire tension member is formed using a rail having a guide slit as a mounting aid, the tension position and pitch of the wire can be easily adjusted.
In the case where the wire guide is provided on the rail surface so as to be rotatable about an axis orthogonal to the rail surface, and the wire tensioning member is used, the wire tensioning direction is determined arbitrarily and automatically along the tensioning direction. be able to.
A wire guide that uses a clamp as a mounting auxiliary member can easily perform positioning, attachment, and removal of the wire guide with respect to a wire tension object.

[Example 1]
FIG. 3 shows a typical structure of the pergola 1. A left-right column 2a, 2b and a rafter 4 connecting these upper ends constitute a gate-shaped structure 11. A plurality of them are arranged in the direction, and these upper portions are connected by left and right girders 3a and 3b which are long in the front-rear direction. The left and right columns 2 a and 2 c are fixed to the foundation 12.
In the figure, the main part is exaggerated and greatly illustrated.
The girder 3 uses an H-shaped steel material in this embodiment, and the end of the rafter 4 is locked and fixed between the upper and lower webs. A horizontal member 6 (in this embodiment, a profile with a slit) is attached to the upper surface of the beam 3 in the front-rear direction.

The pergola 1 is provided with a wire 5 for entwining a vine.
The wire 5 is continuously raised from the left eyebolt 13 fixed to the foundation 12 along the left side surface portion A of the pergola 1, and the ceiling surface portion B is radiated horizontally from the left end of the reached ceiling surface portion B. The right eye bolt 14 is fixed to the right eyebolt 14 which is lowered along the right side surface portion C from the right end thereof and the tip of which is fixed to the foundation 12.
Reference numeral 15 is a turnbuckle for adjusting the wire length.

  And the wire extending | stretching member 17 is arrange | positioned in the bending location of the path | route (wire path | route) of the wire 5 from the said eyebolt 13 to the eyebolt 14, ie, the left end and the right end of the ceiling surface part B. FIG. The wire tension member 17 includes a wire guide 16 according to the present invention, a mounting aid 18 (described later), and the horizontal member 6.

The wire guide 16 (FIGS. 4 to 7) basically includes a case 19, a grooved pulley 20, and a stopper 21, and in this embodiment, also includes a wire pressing rod 22.
The case 19 is obtained by pressing a steel plate having a thickness of 2 mm, and has a long groove shape in the front-rear direction having a bottom wall 23 and left and right side walls 24 (24a, 24b).
The grooved pulley 20 is made of tough hard nylon in this embodiment, and a pair is arranged in the case 19 with a space in the front-rear direction and is rotated by a shaft 25 installed between the side walls 24. Supported as possible. As shown in FIGS. 4B and 4C, the grooved pulley 20 is formed with a groove 27 having a circular arc cross section between the left and right flanges 26.

The stopper 21 is obtained by pressing a steel plate having a thickness of 2 mm, and has a U-shape including left and right leg pieces 28 (28a, 28b) and a connecting piece 29 connecting these tips.
The stopper 21 is pivotally supported by the side wall 24 of the case 19 at the lower portions of the leg pieces 28a and 28b (axially supported portions 30a and 30b).
The leg piece 28 of the stopper 21 has such a length that the connecting piece 29 can go over the front end or the rear end of the case 19 to the lower surface side of the case 19 (FIG. 5).
The stopper 21 is a friction stop mechanism of “difficulty of finger operation” which has strong resistance to the operation when the stopper is rotated by putting a finger on the connecting piece 29.

Specifically, the friction stop means that the bent wire 5 is difficult to turn when it is not rotated by the bending restoring force of the wire when the bent wire 5 tries to return to the original state under a certain tension. In the embodiment, a rivet is used to pivotally support the leg piece 28 of the stopper 21 to the side wall 24 of the case 19, and the nylon piece round washer is interposed between the inner surface of the leg piece 28 and the side wall 24 and firmly fixed. In this way, the “difficulty of finger operation” has been realized. Such “difficulty of finger operation” may be maintained while the stopper 21 is repeatedly rotated at most about 10 times from the application of the wire guide 16.
Engagement recesses 31 for engaging the wire 5 are provided at both sides in the width direction in the center of the connecting piece 29 of the stopper 21.

Corresponding to each of the grooved pulleys 20, the wire holding rods 22 are laid and fixed between the side walls 24 at intervals above which the wires 5 can be inserted.
The mounting aid 18 is used to attach the wire guide 16 to the horizontal member 6. In this embodiment, the rotating shaft 32, the clamping plate 33, the spring washer 34, and the profile 35 having a slit in the longitudinal direction, (FIG. 8). The rotating shaft 32 has a bolt shape, and a tip portion is a male screw, and a corresponding female screw hole is formed in the clamping plate 33. The shape member 35 is a shape member formed by extrusion molding of an aluminum alloy.

The rotating shaft 32 passes through the center portion of the bottom wall 23 of the case 19, and a clamping plate 33 is attached to the rotating shaft 32 below the bottom wall 23. The width of the sandwiching plate 33 is narrower than the width of the slit formed on the upper surface of the horizontal member 6, and the length of the sandwiching plate 33 is larger than the width of the slit and is larger than the internal width of the horizontal member 6. Also has a short elongated shape.
A head portion 36 formed at the upper end of the rotating shaft 32 has a tool hanging portion so that the rotating shaft 32 can be rotated. The spring washer 34 is interposed between the lower surface of the head 36 and the bottom wall 23 of the case 19.

  When the wire 5 is stretched on the pergola 1, the horizontal member 6 is stretched across the rafter 4 in the front-rear direction and fixed, and the wire stretcher member 17 is used on the upper surface of the horizontal member 6. A guide 16 is arranged. In this embodiment, the wire 5 is formed by spirally winding a synthetic resin wire 38 around a steel cable 37 (FIG. 9).

First, a necessary number of wire guides 16 are attached to the shape member 35 of the wire tension member 17. A mounting aid 18 is used for attachment. Specifically, the clamping plate 33 of the mounting aid 18 is placed inside the shape member 35 so as to be aligned with the slit of the shape member 35 and then rotated to be engaged with the ribs on both sides of the shape member 35 from the inside. The wire guide 16 is attached to the shape member 35 by inserting the clamping plate 33 into the shape member 35 from the end cut end of 35.
At this time, the case 19 crosses the upper surface of the shape member 35 in the width direction, and one (rear) grooved pulley 20 is arranged so as to protrude outward from the side wall 24 a outside the shape member 35.
Then, the wire guides 16 are arranged on the shape member 35 at a set interval (pitch), and a tool is put on the head portion 36 of the rotating shaft 32 to rotate the drawing plate 33 toward the shape member 35. Fix the position. This position can be adjusted as appropriate by loosening the drawing of the clamping plate 33.

Next, the shape member 35 is placed on the upper surface of the horizontal member 6 and fixed using screws or attachment hardware. Then, the wire 5 having one end fixed to the foundation 12 is raised along the left side surface portion of the pergola 1, and the tip is inserted into the wire guide 16 at the left end of the ceiling surface portion B (FIG. 8 [B]). At this time, the wire 5 is fitted into the grooves 27 of the front and rear grooved pulleys 20 and passes between the pulleys 20 and the wire pressing rods 22 and through the inside of the portal stopper 21.
The wire 5 rising on the left side surface portion A of the pergola 1 is bent in the horizontal direction toward the ceiling surface portion B by a rear grooved pulley 20 in the wire guide 16.
The wire 5 is supported by the grooved pulleys 20a and 20b, and the wire pressing rod 22 prevents the wire 5 from escaping from the case 19.

When the wire 5 is sufficiently tensioned in the ceiling surface portion B, the stopper 21 of the wire guide 16 is tilted forward, and the wire 5 is engaged with the engagement recess 31 of the connecting piece 29 (broken line in FIG. 9). Then, even if the pulling force of the wire 5 is loosened, the direction of the force that the wire 5 tries to return is almost the direction of the leg piece 28 of the stopper 21, and the bending restoring force of the wire 5 that rotates the stopper 21 upward is the leg. Since it balances with the friction stop of the axial support location 30 of the piece 28, the wire 5 does not loosen backward.
When a spiral wire is used as the wire 5, pulling back is prevented even when the wire 38 wound around the steel cable 37 is caught by the stopper 21.

Next, the wire 5 is moved to the right end of the ceiling surface portion B and the same operation is performed to maintain the wire 5 in a tensioned state on the ceiling surface portion B. Further, the wire 5 is lowered from the right end of the ceiling surface portion B to the right side surface portion C. After sufficiently tensed, the lower end of the wire 5 is fixed to the eyebolt 14 fixed to the foundation 12. At this time, if a turnbuckle is interposed between the lower end of the wire 5 and the eyebolt 14, the expansion and contraction of the wire 5 due to a change in temperature or the like is absorbed, and the tension state of the wire 5 can be maintained well.
In the state in which the wire 5 is stretched, the wire 5 passing through the case 19 of the wire guide 16 in the ceiling surface portion B is guided by the pair of front and rear grooved pulleys 20a and 20b. It does not bend and the wire 5 does not contact the side wall 24 of the case 19.

Since one grooved pulley 20 of the wire guide 16 protrudes to the outside of the shape member 35, the wire 5 is stretched away from the left side surface portion A and the right side surface portion C of the pergola 1, and the shape material 35 and the pergola 1 are stretched. There is no contact with the (wire tension object).
Furthermore, since the front grooved pulley 20 is pressed downward by the wire 5 when the wire 5 is stretched, the wire guide 16 is stably attached to the pergola 1 at both left and right ends of the ceiling surface portion B.
This operation is repeated, and the necessary number of wires 5 are stretched over the entire pergola 1. The wire 5 to be used is one continuous at the left side surface portion A, the ceiling surface portion B, and the right side surface portion C.

In the above description, the wire guide 16 has a direction in which the direction of the wire 5 in the ceiling surface portion B is perpendicular to the longitudinal direction of the profile member 35 (longitudinal direction of the beam 3), but it can also be obliquely crossed as shown in FIG.
Further, by loosening the mounting aid 18 and then tightening it again, it is possible to adjust the spacing or angle of the wire guides 16 that are attached to the arrangement interval or in an orthogonal state at the site.
The wire extending member 17 is the wire guide 16, the mounting aid 18, and the shape member 35. However, it is only necessary that the wire guide 16 can be attached to the pergola 1, and the shape member 35 has a rotating shaft 32 on a square tube without a slit. A female screw hole for screwing may be formed.

Further, the wire tension member 17 may be a combination of the wire guide 16, the mounting aid 18, and the clamp 39 (FIG. 11).
The clamp 39 has a U-shaped main body 40 and a bolt 41 that passes through the lower side of the main body 40 and is screwed from below. The wire guide 16 is fixedly or rotatably attached to the upper side of the main body 40 by the mounting aid 18.
The attachment structure of the wire guide 16 by the clamp 39 can be easily attached when the girder 3 of the pergola 1 has a web projecting horizontally such as an H-shaped steel material, and the adjustment of the interval is also easy.

[Example 2]
FIG. 12 shows the second embodiment, and as in the first embodiment, the wire guide 16 includes a case 19, front and rear grooved pulleys 20, a stopper 21, and a wire pressing rod 22, but there is no mounting aid 18. The wire tension member 17 is not configured.
In other words, the wire guide 16 alone is configured. However, even with such a wire guide 16, for example, when the girder 3 is formed of an H-shaped steel material, the wire guide 16 is simply placed directly on the upper surface thereof. Alternatively, the wire 5 can be stretched by fixing it using an adhesive or the like, and then wrapping the wire 5 in the same manner as described above.
Although the wire guide 16 is easy to move during the tensioning operation, after the wire 5 is tensioned, it is stabilized by the frictional force between the case 19 of the wire guide 16 and the upper surface of the beam 3.
In this embodiment, since the mounting aid 18 is not provided, the cost is low, and the time required for wire stretching is small.

Example 3
FIG. 13 shows a third embodiment, which is different in that the wire holding rod 22 included in the wire guide 16 of the second embodiment is not provided. The wire holding rod 22 needs to be careful not to jump out from the case 19 of the wire guide 16 when the wire 5 is stretched, but it is not essential.
This type of wire guide 16 uses a large number according to the number of wires 5 to be stretched, and is a member that is less likely to be replaced or adjusted once the wires 5 are stretched. Therefore, an inexpensive structure is desired.

The embodiment has been described above.
The wire guide 16 of the present invention can be used not only for the pergola 1 but also for a carport, a covered terrace, a balcony, and the like. The angles of the side surface portion and the ceiling surface portion are not limited to vertical and horizontal, and the angle along the vertical surface where they intersect is not limited to a right angle. Further, the wire 5 may be stretched not only in the lateral direction from the left side surface portion A to the right side surface portion C such as the pergola 1 but also in the vertical direction from the front surface portion to the rear surface portion.
Generally, when the wire 5 is stretched, the wire 5 can be used at a location where the wire 5 is greatly bent.
The wire guide 16 of Example 1-Example 3 may be used in combination.
The directions such as front and rear, right and left used in the specification are for convenience of explanation, and are actually relative.
