Description

  In the present invention, for example, a wire is stretched between support bodies (tensioned and fixed at both ends) like a fence that regulates the entrance and exit of a person by stretching a wire between standing columns (between support bodies). It is related with the wire attracting metal for doing.

  A structure in which a wire is stretched between supports (supports) is often used for fences, wire guards, and the like. Also, there are horizontal, inclined, and vertical directions in which the wire is stretched. In both cases, one end of the wire is fixed to one support body and the other end is fixed to the other support body in the tensioning.

  A threaded terminal is often used to secure the end of the wire to the support. The thread terminal has a screw part at one end and a wire fixing part at the other end, and fixes one end of the wire to the wire fixing part by caulking or the like, and directly attaches the screw part at one end to the support body to attach the end of the wire. It is connected to the support. Usually, a cover is attached to the thread terminal to adjust the appearance of the connecting portion with the support, but this cover is easily removed from the position of the thread terminal by mischief.

  Patent Document 1 is an improvement on this point. The opening of the case 9 (cover) is screwed into the wire pulling screw ring 14, and the wire pulling screw ring 14 is fixed to the support column 2 (support). The cap bolt 12 is rotatably fitted at a fixed position. The case 9 has a structure in which a stopper 11 fixed by crimping one end of the wire 6 is engaged inside, and the wire 6 is tensioned via the case 9 by rotating the wire drawing screw ring 14. Yes. A special tool is required to rotate the wire screw ring 14.

  In this structure, each member for fixing the end portion of the wire is housed in the case 9 so that the appearance is good. Further, when the case 9 is sufficiently pulled, the wire drawing screw ring 14 is located inside the case 9. It is hard to be tampered with because it gets in and requires a special tool for rotation.

JP 2001-65645 A

However, the above-mentioned wire mounting hardware has a special structure in which the wire end is fixed to the stopper 11 and is housed inside the case 9, which increases the cost of the product.
It is an object of the present invention to provide a wire attachment hardware that can reduce the cost of a product using a popular thread terminal and that a cover attached to a connecting portion with a support is not removed by tampering.

  A threaded terminal with a wire fixed at one end is connected to a rod screw attached to the support using a tether. A washer is interposed between the support and the connecting material, and a stopper ring is provided on the washer. Determine the position of the thread terminal with respect to the connecting material and fix it with the nut. The cover is sized to accommodate the washer, connecting material, deciding nut and thread terminal. The cover is simply cut and both ends are open. A stopper ring is fitted on the inner peripheral surface of one of the openings. An engaging groove is provided.

The thread terminal is decorated with a cover, and the appearance of the connecting portion between the support and the wire is good.
The cover is rotatable, but is engaged with the stopper ring, so that the cover is idle, and the tether and the determining nut are not loosened by mischief.
Since a washer is interposed between the support and the connecting material, and a stopper ring that engages the cover is provided on this washer, the rotation and vibration from the cover are buffered by the washer, and the rotation and vibration to the connecting material are prevented. There is little to be transmitted. For this reason, it is unlikely that the connecting material and the decision nut will loosen.
The cover is a simple pipe having both ends open and can be obtained at low cost.

[Example 1]
FIG. 1 shows a horizontal handrail 1, and a handrail bar 6 is installed on the upper ends of supports 2 to 5 erected on the floor surface. In the space between the handrail bar 6 and the floor surface, a fence-type wire device 8 using wires 7 (7a, 7b) is provided in order to prevent penetration or falling. The supports 2 to 5 are also supports in the wire device 8, and in this embodiment, a simple form is obtained by cutting a thick plate metal into a rectangle. Hereinafter, the starting point support 2, the intermediate support 3, the relay support 4, and the end point support 5 are referred to from the left in the figure.

  The starting point support 2 is located at the starting point of the wire device 8 and attaches the starting point of the wire 7, and the end point supporting member 5 is located at the end point and attaches the end point of the wire. The relay support 4 is for connecting and joining the end of the start point side wire (referred to as the first wire 7a) and the end point of the end point side wire (referred to as the second wire 7b). Further, the intermediate support 3 is for supporting the intermediate portion when one wire 7 is long, and merely has a through-hole through which the wire 7 is passed. These supports 2, 3, and 4 are arranged in parallel so that the thickness dimension appears in a front view, and their bases are firmly fixed in the foundation concrete. Each of the supports 2, 3, 4 is not inclined or bent by the tension of the wire 7. When the tension of the wire 7 is increased, the starting point support 2 and the end point support 5 positioned at both ends of the handrail 1 are reinforced. The wire 7 is cut into a predetermined dimension according to the support interval.

  The wire device 8 has one end of the first wire 7a attached to the starting point support 2 using the starting point wire mounting hardware 9, and the other end fixed to the relay supporting body 4 using the relay wire mounting hardware 10, Then, one end of the second wire 7b is attached to the relay support body 4 using the relay wire mounting hardware 10, and the other end of the second wire 7b is attached to the relay support body 4 positioned next. It becomes the state attached using. The wire device 8 having a length designed by repeating this state is configured. The other end of the last second wire 7 b is fixed to the end point support 5 using the end point wire attachment hardware 11. When the wire device 8 is constructed in a closed shape like a circle, the start point support 2 and the end point support 5 are not provided, and the relay support 4, the relay wire mounting hardware 10, and the intermediate support 3 are used. Sometimes it is done.

The start point wire attachment hardware 9 and the end point wire attachment hardware 11 are the same, but the right and left screws are reversed. Moreover, the same wire attachment hardware 10 can be used for any relay support 4.
In addition, although the attachment from the starting point support body 2 to the end point support body 5 was shown sequentially, it does not need to be stretched sequentially and can be stretched from any support as a unit between the supports.

FIG. 2 shows a wire attachment metal 9 for the starting point, which is attached to the starting point support 2. The hardware 9 includes a screw rod 12, an end nut 13, a washer 14, a connecting material 15, a fixing nut 16, a thread terminal 17, and a cover 18.
As shown in FIG. 3, the washer 14 is an annular member that can be fitted into the screw rod 12, and a stopper ring 20 is loosely attached to the groove 19 on the outer peripheral surface.
The stopper ring 20 is a ring-shaped spring steel ring with a part cut away. The stopper ring 20 is slightly larger in diameter than the bottom diameter of the groove 19 of the washer 14, and has elasticity in the direction of expanding and reducing the diameter.

The thread terminal 17 has a threaded portion 21 protruding from the starting point side, a wire fixing portion 22 on the relay side, and a tool hook portion 23 in the middle portion thereof. The tool hanging portion 23 is a portion that is flattened or hexagonal by notching a part of the circumference for hanging the tool. The first wire 7a is fixed to the wire fixing portion 22 by means such as caulking.
The connecting member 15 has a long nut shape with female screws on both sides. The rod screw 12 is screwed to the female screw on the start end side, and the screw portion 21 of the thread terminal 17 is screwed to the relay side. In this embodiment, the female threads on both sides of the connecting material 15 are different in the screw direction between right and left threads.

  As shown in FIG. 4, the cover 18 has an inner diameter capable of accommodating the washer 14, the connecting material 15, the fixing nut 16, and the thread terminal 17 in a form in which the end portion is simply crossed across the stainless steel pipe. The size and the length are set so as to slightly exceed the tool hanging portion 23. In this embodiment, the washer 14 and the tool hook 23 have an outer diameter that is slightly smaller than the inner diameter of the cover 18, and also serve as a guide and a receiving member that prevents rattling when the cover 18 is mounted. Yes.

  The cover 18 further has an engagement groove 24 that engages with the stopper ring 20 on the inner peripheral surface of the opening on the start end side. 4B, the inner surface on the opening side is formed in a terrace shape in cross section with the first tapered surface 25 and the second tapered surface 26, and the first tapered surface 25 is in the axial direction. The second tapered surface 26 is inclined at an angle of about 45 degrees. The second tapered surface 26 is an opening side groove wall of the engagement groove 24.

Accordingly, the operation of fitting the cover 18 to the washer 14 is easy, and the operation of pulling out from the washer 14 (moving in the axial direction of the cover) is difficult unless a tool is used.
In this embodiment, the axial dimension from the engagement groove 24 of the cover 14 to the opening end surface is made slightly shorter than the dimension from the stopper ring 20 of the washer 14 to the relay side surface of the starting point support 2. is there. Thereby, the cover 14 is attached to the start point support 2 so that the opening end thereof is close to, for example, the width of the engagement groove 24.

The relay wire mounting hardware 10 is arranged on both sides of the relay support 4 with the bar screw 12 in common, but is basically the same as the starting wire mounting hardware 9. That is, the screw rod 12 is a single screw rod 12 in which the start point side and the relay side are integrated, and on the start point side of the relay support body 4, a washer 14 and a connecting material are provided on the portion of the screw rod 12 protruding to the start point side. 15. A structure provided with a deciding nut 16 (a structure symmetrical to the wire fitting 9 for the starting point, and therefore the screw is a left-hand thread), and a screw protruding toward the end point side on the end point side of the relay support 4 The same configuration as that of the starting wire attaching hardware 9 is arranged in the portion of the bar 12.
The end-point wire mounting hardware 11 has a symmetrical configuration (the screw is a left-hand thread) with respect to the start-point wire mounting hardware.

The wire 7 is stretched as follows.
The thread terminal 17 is caulked and fixed to both ends of the wire 7a (or 7b), and the determined nut 16 is screwed into each screw portion 21 as appropriate. Also, the covers 18 are fitted from both ends of the wire 7a. These mounting directions are symmetrical. When the intermediate support 3 is present, the end of the wire 7 is fixed to the thread terminal 17 after passing the wire 7 through the intermediate support 3.

  The screw rod 12 is passed through the starting support 2, the end nut 13 is screwed on the opposite side to the relay side, the washer 14 is fitted into the screw rod 12 protruding to the relay side from the support 2, and the connection The material 15 is screwed into a temporarily fixed state. A stopper ring 20 is mounted in the groove 19 of the washer 14. At this time, care is taken so that the washer 14 and the support 2 are not rattled in the axial direction, but are not pinched tightly.

  The threaded rod 12 is also passed through the relay support 4 so that the respective washers 14 (with the stopper ring 20 attached) are fitted on both the start point side and the end point side, and the connecting material 15 is screwed and temporarily fixed. Keep it as Although the arrangement is symmetrical with respect to the end point support body 5, the bar screw 12, the washer 14 (same as above), and the connecting material 15 are screwed in the same manner as in the case of the start point support body 2 so as to be temporarily fixed.

  The two workers hold the thread terminals 17 at both ends of the wire 7a one by one, rotate the thread terminals 17 together with the wires 7a in accordance with breathing, and connect the starting point side connecting material 15 (right screw) and the relay side connecting. The threaded portion 21 of the thread terminal 17 is screwed into the female thread (left thread) of the material 15. A tool hook 23 is used for screwing the screw portion 21 and a tool is used.

  At this time, the deciding nut 16 is disposed at a position having a sufficient margin for the screwing amount of the thread terminal 17, and when the thread terminal 17 is sufficiently screwed and a necessary tension is applied to the wire 7a, It turns to the connecting material 15 side, presses strongly against the end of the connecting material 15, and fixes the position of the thread terminal 17 with respect to the connecting material 15. Thereafter, similarly, the wire 7 is stretched between the relay support bodies 4, and finally, the wire 7 b is stretched between the relay support body 4 and the end point support body 5. As described above, when the wire 4 is routed in a closed figure such as a circle, all the support bodies become the relay support bodies 4. However, there is no special case in the attachment procedure.

Next, the cover 18 is moved toward the support bodies 2, 4, 5, and the engagement groove 24 of the opening is engaged with the stopper ring 20 of the washer 14. This operation can be performed only by pushing the cover 18 strongly toward the support body 2 because the first tapered surface 25 of the opening is gently inclined.
Thus, the wire 7 is attached to each of the supports 2 to 5, and the thread terminal 17, that is, the connection portion with the support is beautifully covered with the cover.

  FIG. 6 shows another example [embodiment 2] of the wire attachment fitting 9 for the starting point, and the wire attachment fitting for the end point can have the same structure (the screw direction is reversed). In this starting point wire mounting bracket 9, the structure composed of the bar screw 12 and the end nut 13 is changed to a headed bolt 28, thereby simplifying the structure.

As described above, after the supports 2 to 5 are erected and the handrail bar 6 is fixed, the wire device 8 is completed in the lower space.
The dimension from the groove 19 (the stopper ring 20 engages) in the opening of the cover 18 to the opening end is the axis from the stopper ring 20 in the washer 14 to the support (starting end support, relay support, end support). Since it is only slightly smaller than the directional dimension, there is almost no gap between the cover 18 and the support body, and the appearance of the connecting portion becomes clean and smart.

  The operation of returning the cover 18 to the side opposite to the direction in which the cover 18 is engaged (the axial operation) is because the second tapered surface 26 in the opening of the cover 18 is engaged with the stopper ring 20. Due to the large angle, the cover 18 cannot be removed unless a large force is applied using a tool. For this reason, the cover 18 is removed, and there is no possibility of being tampered with by the connecting material 15 inside.

Although the embodiment has been described above, a spring washer 28 may be further interposed between the washer 14 and the connecting material 15 as shown in FIG. 7 [Example 3]. The rotation and vibration transmission from the washer 14 to the connecting material 15 are further buffered, and the anti-loosening effect is high.
In the start point support body 2 and the end point support body 5, the end nut 13 (FIG. 2) exposed to the outside, the head of the headed bolt 27, and the like are made of synthetic resin to prevent the risk of injury and to improve the appearance. The end cover 29 may be attached.

The threaded portion 21 of the thread terminal 17 is a male screw in the first embodiment, but may be a female screw in relation to the connecting material 15.
As shown in FIG. 8, the wire device 8 can be stretched in an inclined state by using the inclined connection fitting 30 [Embodiment 4]. The inclined connection fitting 30 includes an attachment member 31 and a rotation member 32. The rotation member 32 has a hinge structure that is rotatable about the shaft 33 on the attachment member 31, and a screw corresponding to the rod screw 12 at the tip. The unit 34 is provided. The attachment member 31 is attached by being screwed to an attachment screw 35 penetrating a support (for example, the starting point support 2).
