Description

The present invention relates to a pseudo-tree fence constructed by combining a post and a fence that are arranged to divide a predetermined area in a park, a ranch, a promenade, or the like, and whose appearance resembles a tree.

Conventionally, a pseudo-tree fence is used to partition a predetermined area in a park, a ranch, a promenade or the like. Pseudo-wood fences are constructed by combining struts and rungs that are molded mainly from recovered plastic and resemble wood, and are often used in recent years because they save wood resources and are more durable than wooden fences. It is like that.
Such a pseudo-tree fence is formed such that a recess is formed in a support column, and a rung is spanned between the recesses of the pair of support columns so that the rung does not fall out of the recess. Although various improvements have been made as means for constructing the artificial wooden fence, Patent Documents 1 and 2 are shown as examples.
In general, as a means for fixing the rung to the support, for example, as shown in Patent Documents 1 and 2, a fastening member such as a bolt member is arranged between the rungs on both sides of the support to fix the rung. Yes. For example, as shown in FIG. 6 and FIG. 9 of Patent Document 2, the fastening member is housed in the state completely surrounded by the post of the pseudo-tree fence and the cross, and thus is not exposed to the outside.

However, when a pseudo-fence is actually installed and the time elapses, there may be a slight gap between the support and the cross. This is because even if it is made of plastic, individual elements become thin as if they were made of real wood over time, and the main cause is the decomposition and leakage of organic components due to high temperatures and ultraviolet rays, especially in summer. (Volatilization) and so on. For this reason, there may be a slight gap between the support and the rung that are in close contact with each other at the beginning. Then, rainwater may infiltrate from this gap, and the steel members that become the fastening members, the columns, and the pipes of the crossbars may rust. In addition to rainwater, in the coastal area, splashes containing seawater blown by strong winds may infiltrate, and in that case the rust will be greater (hereinafter referred to as rainwater including rainwater and seawater splashes) . Therefore, there has been a demand for a technique that prevents the internal metal member from being rusted even if a slight gap is generated between the support column and the rung after a lapse of time.
The present invention has been made paying attention to such problems existing in the prior art. The purpose is to provide a pseudo-wood fence that does not rust the internal metal members even if a gap is generated between the column and the rung after a lapse of time.

In order to solve the above-mentioned problem, in the means 1, in the pseudo-tree fence configured so as to span a cross between a plurality of upright columns, the first and A metal connection in which a second recess is formed, a pressing portion is formed on one side and a first screw means is formed on the other side of the communication hole communicating between the two recesses that open to the bottom surfaces of the both recesses A scissors are inserted, the pressing part is disposed on the second recess side, the first screw means is disposed on the first recess side, and the connecting scissors are respectively disposed in the first and second recesses. Hollow first and second bellows that are foldable and elastic along the axial direction of the connecting rod are disposed at surrounding positions, and the first and second ends of the crosspieces are opposite to each other. Respectively form a first and a second receiving part and the first cross The end portion on the mouth side is fitted into the first recess so that the first bellows body is accommodated in the first accommodating portion, and the rung is relatively approached to the support column. A first holding structure that compresses the first bellows body and holds the first bellows body in a biased state with respect to the bottom surface of the first recess; and The second bellows body is fitted into the second recess so that the second bellows body is housed in the second housing portion, and the crosspiece is moved relatively close to the support column. A second holding structure that compresses the second concave portion and holds the second concave portion in a biased state with respect to the bottom surface, and a second screw formed in the first accommodating portion of the first end face of the first end And a structure for fixing the crosspiece to the support by a screw action by screwing the first screw means into the means. And effect.

In such a configuration, when fixing the end portion of the first lug surface side of the cross to the support, first, the first bellows body arranged at a position surrounding the connecting rod is in the first housing portion. Is fitted in the first recess. Then, the first bellows body is pushed and compressed by the crossbar and is held in a biased state on the bottom surface of the first recess. That is, the first bellows body in which the front and rear ends are in contact with the crosspiece and the support post is held in the biased state in a state of surrounding the connecting rod. Note that the first bellows body disposed between the crosspiece and the support may be in direct contact with the crosspiece or the support or may be interposed with a cushion material or a spacer (that is, indirect contact). Next, the first screw means of the connecting rod and the second screw means formed near the end of the second crosspiece are in a fastening relationship. For example, the first screw means includes a male screw, and the second screw means includes a female screw. In this case, since the force that moves in the axial direction is generated by the pressing force of the inclined surfaces of the threads of the male screw and the female screw generated by tightening the screw, the crosspiece that moves integrally with the second screw means is It will be fixed relatively close to the column. The first bellows body is further compressed if the crossing and the support are relatively closer due to this screw action.
On the other hand, the second bellows body is pushed and compressed by the crosspiece by bringing the end portion of the second wooden mouth surface side of the crosspiece relatively close to the support column and is biased to the bottom surface of the second recess. Will be held. Even on this side, the second bellows body sandwiched between the cross and the support post is held in an energized state in a state of surrounding the connecting rod.
Here, the crossbars may be considered to be arranged between a pair of columns with the front end side of one crossbar being the first crossbar and the rear end side being the second crossbar. Further, the first rung and the second rung may be considered as separate rungs. For example, in the rung arranged at the extreme end of the fence, a hollow portion is formed only on one end face. The fixing work to the support of the crosspiece may be fixed from either the first or the second end surface, or may be performed simultaneously.
The bellows body is not particularly limited as long as it is hollow, can be folded along the axial direction of the connecting rod, has elasticity, and has a biasing force by being compressed.
In this way, the first and second bellows bodies completely surround the connecting rod with the front and rear ends being in contact with the crosspiece and the support column, so that a gap is generated between the crosspiece and the support column over time. In other words, the first and second bellows bodies that are in a compressed state will extend with the clearance corresponding to the gap between the first and second bellows, even if there is a gap between the cross and the column. Since it is covered with a bellows body, rainwater or the like is not directly hit, and rust is prevented.

In the means 2, the tip of the first and second concave portions of the first and second bellows bodies contacting the bottom surface is in contact with the bottom surface at all edges. The gist.
By configuring in this way, rainwater or the like that has entered from the gap between the rung and the prop travels through the inside and enters the bellows body from the tip of the bellows body (that is, the contact surface on the pillar side). Can be prevented. Further, in this case, the entire edge of the bellows body is preferably in contact with the outer side of the communication hole of the support column, so that rainwater or the like does not enter in the direction of the communication hole.

The gist of the means 3 is that at least one of the first and second bellows bodies is forcibly fitted in the first or second accommodating portion of the crosspiece. .
By constructing in this way, the bellows body is forcibly fitted in the hollow portion even if rainwater or the like that has entered from the gap between the crosspiece and the prop is transmitted through the inside, so that the wall surface of the hollow body Since it is blocked by the closely attached bellows body, rainwater or the like is less likely to enter the bellows body. Further, when the hollow portion is expanded outward as in the means 6, the bellows body is firmly and forcibly fitted on the narrow side of the hollow portion, that is, on the side close to the crosspiece side, and in the direction of the crosspiece. Infiltration of rainwater is prevented.

In the means 4, a metal pipe is inserted through the rung so that the end portions are exposed in the first and second accommodating portions, and at least one of the first and second bellows bodies. is the end of the bellows body is brought into contact with the rungs side so as not to protrude outward from the inner circumferential surface the bellows body before Kipa type in the first or in the second housing portion of the crossbar The gist of this is
In other words, when one end of the bellows body is in contact with the crosspiece (the other end is in contact with the column side), the inner circumferential surface of the metal pipe of the crosspiece is always located inside the bellows, so the pipe It becomes difficult for rainwater or the like to enter inside, and rusting of these members is prevented.
In the means 5, a metal pipe is inserted through the rung so that ends thereof are exposed in the first and second accommodating portions, and at least one of the first and second bellows bodies is inserted. the bellows body of a gist thereof being disposed on the outer periphery position before Kipa type in the first or in the second housing part of the crossbar.
As a result, when a metal pipe is inserted near the center of the cross, the bellows body is disposed on the outside thereof, so that it is difficult for rainwater or the like to reach the pipe.
The gist of the means 6 is that the rear end of the bellows body, which is arranged at the outer peripheral position of the pipe of the crosspiece, is arranged at a position retreated from the tip of the pipe of the crosspiece. .
This makes it difficult for rainwater or the like transmitted through the outer surface of the bellows body to flow in the direction of the pipe of the cross, so that rainwater or the like does not reach the pipe in addition to the means 4 or 5, and rust of these members is prevented.
The gist of the means 7 is that at least the lower side wall surface of at least one of the accommodating portions opened in the first or second end face is formed to expand outward.
By adopting such a configuration, the rainwater that has entered from the gap between the rung and the column is not stagnated inside and is discharged to the outside through the expanded slope portion of the hollow portion. In particular, the lower half of the hollow portion is preferably configured in this way, but the upper half is preferably not spread outward because rainwater or the like is not transmitted to the back of the cross. However, since there is a problem in molding, it is preferable that the lower half of the hollow portion is expanded outward and the tube is parallel to the axial direction from the center to the upper side.

In the means 8, a cylindrical body is disposed between the pressing portion and the bottom surface of the second recess, and the second bellows body surrounds the outer periphery of the cylindrical body. It is arranged in the second accommodating portion, and the first screw means is screwed into the second screw means to move the pressing portion to the column side to press the cylindrical body, The gist is that a restricting member for restricting relative rotation between the rung and the cylindrical body is provided.
In such a configuration, when the first screw means of the connecting rod and the second screw means formed near the end of the second crosspiece are in a fastening relationship, the pressing portion moves relatively in the column direction. The cylinder is pressed against the bottom surface of the first recess. As a result, the cylindrical body is made unrotatable by the frictional force with respect to the column. By this fastening, the first rung is pressed toward the bottom surface of the first recess and the second rung is pressed toward the bottom surface of the second recess, so that both rungs do not fall out of the first and second recesses.
Furthermore, prevention of the movement in the axial direction and circumferential direction of the first crosspiece is executed by the regulating member. Specifically, for example, as in the embodiment, the screw member can be screwed into the screw hole and the tip of the screw member can be brought into contact with the side surface of the cylindrical body. In this case, since the cylindrical body is inserted into the second bellows body, the cylindrical body does not interfere with the expansion and contraction of the second bellows body.

  According to the invention of each claim, even if a gap is generated between the support column and the cross bar over time, the connection rod can be always surrounded by the bellows body, the support column and the cross bar arranged at both ends thereof, The rainwater that has entered will not be directly hit, and rusting of the connecting rod will be prevented. Further, when a metal member other than the connecting rod is surrounded, rust is prevented in the same manner.

Hereinafter, specific embodiments of the mounting structure of the crossbar in the pseudo-tree fence of the present invention will be described based on the drawings.
(Embodiment 1)
First, an outline of the pseudo-wood fence will be described based on FIG. The pseudo-tree fence 10 is constructed by combining a support 11, a cross 12 and a sub-cross not shown. The support posts 11 are arranged in series at a predetermined interval, and a crosspiece 12 is stretched between a pair of front and rear support posts 11. A sub rung is attached to the column 11 located at the end of the pseudo-tree fence 15. The sub-rail is formed with a structure that can be connected to the column 11 only on one small facet. The support | pillar 11, the crosspiece 12, and the sub crosspiece are comprised from the cylinder made from a plastic, and each exposed outer peripheral surface and the end face are made into the texture resembling the skin of a tree. The support column 11 is erected on the ground. For example, as shown in FIG. 4, the base of the support column 11 is held by a foundation footing unit 17 disposed on a split stone 16 in the ground.

Next, the configuration of each member and the attachment structure between the members will be described in more detail.
As shown in FIGS. 1 to 5, a hollow portion 18 is formed in the column 11 along the center in the axial direction. The hollow portion 18 is opened on the base end side end face of the support 11 (not shown), and the upper end side end face 11a side is not opened but is sealed. An alloy reinforcing pipe 19 is mounted in the hollow portion 18 so as to be in contact with the inner peripheral surface of the hollow portion 18.
First and second recesses 20 and 21 are formed on the opposing outer peripheral surface near the upper end of the column 11 and sandwiching the hollow portion 18. The first and second bottom surfaces 23 and 24 of the recesses 20 and 21 are flat. Through holes 25 and 26 are formed in both bottom surfaces 23 and 24, respectively. In FIG. 1, the first bottom surface 23 of the first concave portion 20 arranged on the left side is inserted into the small edge surface of the crosspiece 12 arranged at the upper and lower positions sandwiching the through hole 25, and extends in the circumferential direction of the crosspiece 12. A protrusion 27 for preventing rotation is embedded. The protrusion 27 is set when the crosspiece 12 is formed, and is fixed at the current position as the crosspiece 12 is formed and solidified.

As shown in FIG. 4, the pair of front and rear small edges of the crosspiece 12 are a front end portion A and a rear end portion B. As shown in FIGS. 1 to 3 and FIG. The front end A of the crosspiece 12 is fitted, and the rear end B of the crosspiece 12 is fitted to the second recess 21.
A hollow portion 28 having a circular cross section is formed inside the crosspiece 12 along the center in the axial direction. The hollow portion 28 communicates with the first and second accommodating portions 30 and 31 that open to the small facets 12a and 12b near both ends. The first and second accommodating portions 30 and 31 are spaces having a circular cross section that is expanded in a taper shape toward the small-mouthed surfaces 12a and 12b, respectively. An alloy reinforcing pipe 32 is attached to the hollow portion 28 so as to be in contact with the inner peripheral surface thereof. Both end surfaces 32a of the reinforcing pipe 32 are located at the bases of the first and second accommodating portions 30 and 31.
As shown in FIGS. 1 to 5, a cap 33 is fixed to a position in the reinforcing pipe 32 on the front end A side of the crosspiece 12 and facing the end of the reinforcing pipe 32. The cap 33 is arranged at the boundary position between the first accommodating portion 30 and the reinforcing pipe 32. The cap 33 is a dish-shaped member having an outer diameter corresponding to the inner diameter of the reinforcing pipe 32, and a through hole 35 is formed in the center of the bottom surface 34. A female screw 35 a is formed on the inner peripheral surface of the through hole 35.
As shown in FIG. 1 to FIG. 3, the outer periphery of the reinforcing pipe 32 on the rear end B side of the crosspiece 12 and at a position facing directly downward when the crosspiece 12 is attached to the column 11 as shown in FIG. 4. An alloy reinforcing plate 34 is attached. The reinforcing plate 34 is disposed slightly deeper than the end portion of the reinforcing pipe 32 (that is, in a direction away from the facet surface 12b), and a through hole 36 communicating inward and outward in a direction intersecting the reinforcing pipe 32 and the reinforcing plate 34 is formed. Is formed. A female screw 36 a is formed on the inner peripheral surface of the through hole 36. An insertion hole 43 is formed at a position facing the through hole 36. As shown in FIG. 1, the insertion hole 43 faces directly below when the crosspiece 12 is attached to the column 11.

As shown in FIGS. 1 to 5, through holes 25 and 26 formed in the first and second bottom surfaces 23 and 24 are inserted into the first and second recesses 20 and 21 of the support column 11. A connecting bolt 37 is provided. The connecting bolt 37 includes a head section 38 having a regular hexagonal cross section and a rod-shaped main body 39, and a male screw 39 a is formed on the outer periphery of the main body 39 near the tip. A cylinder 40 made of polyethylene foam is disposed between the head 38 and the first bottom surface 23 of the first recess 20 via a washer 46.
First and second bellows 41 and 42 as bellows bodies are disposed in the first and second recesses 20 and 21 and at the outer peripheral positions of the main body 39 and the cylindrical body 40, respectively. The bellows 41 and 42 made of chloroprene rubber are cylindrical bellows bodies having an outer diameter of 75 mm, an inner diameter of 55 mm, and six ridges of 120 mm length and the same thickness. As shown in FIG. 6, both end surfaces of the bellows 41, 42 are configured as flat surfaces, and the inner diameters at the both end surfaces are configured to be slightly larger than the inner diameter of the reinforcing pipe 32.

In the above configuration, a method of fixing the front end A side and the rear end B side of the crosspiece 12 to the support 11 will be described with reference to FIGS. 1 and 2. In the first embodiment, the front end A side of the crosspiece 12 is first fixed, and then the rear end B side is fixed.
First, a fixing method on the front end A side of the crosspiece 12 will be described. With the front side of the connecting bolt 37 projecting toward the first recess 20, the first bellows 41 is disposed so as to cover the connecting bolt 37 exposed in the first recess 20. In this state, the front end portion A side of the crosspiece 12 is fitted into the first recess 20 so that the bellows 41 is accommodated in the first accommodating portion 30 of the crosspiece 12, and the fore end surface 12 a is formed on the bottom surface 23. Make contact. At this time, the protrusion 27 on the side of the support pillar 11 is stuck in the small edge surface 12a of the crosspiece 12 and the rotation of the crosspiece 12 is prevented.
As shown in FIGS. 2, 3, and 5, the connecting bolt 37 that is exposed to the first concave portion 20 side and can be advanced and retracted by the first bellows 41, the reinforcing pipe 32 of the crosspiece 12, and the bottom surface 23. It will always be completely surrounded from the outside. Since the first bellows 41 is disposed between the reinforcing pipe 32 and the bottom surface 23 of the cross board 12 in a state of being compressed and having an urging force, the urging force is released and compressed even if this interval is somewhat widened. The first bellows 41 extends by that amount, and the surrounding state of the connecting bolt 37 is maintained.
Next, the connecting bolt 37 is collated with the through hole 35 of the cap 33, and the male screw 39 a on the connecting bolt 37 side is screwed into the female screw 35 a of the through hole 35. Then, the crosspiece 12 is gradually drawn toward the bottom surface 23 by the screw action of these screws 39a and 35a. The cylinder 40 is pressed between the head 38 of the connecting bolt 37 and the second bottom surface 24 of the second recess 21 with the movement of the crosspiece 12 toward the bottom surface 23, and the first bellows 41 is the first bellows 41. 3 is pressed between the reinforcing pipe 32 and the bottom surface 23 of the crosspiece 12 (the state shown in FIG. 3). In addition, since the cylinder 40 is not so flexible, it does not bend greatly.
Thereby, the fixing of the front end A side of the crosspiece 12 is completed. The front end A of the crosspiece 12 is less likely to turn the connecting bolt 37 in the direction in which the screw is loosened due to the reaction force against the pressing of the cylindrical body 40, and the front end A side of the crosspiece 12 is difficult to drop off from the first recess 20.

Next, a fixing method on the rear end B side of the crosspiece 12 will be described. The front end A side of the crosspiece 12 has already been fixed in advance with respect to the column 11. As shown in FIG. 3, the second bellows 42 is placed over the connection bolt 37 exposed in the second recess 21 with the rear side of the connection bolt 37 protruding toward the second recess 21. To do. Then, in this state, the rear end B side of the crosspiece 12 is fitted into the second recess 21 so that the second bellows 42 is accommodated in the second accommodating portion 31 of the crosspiece 12, and its small facet 12 b. Is brought into contact with the bottom surface 24. At this time, the crosspiece 12 is guided so that the cylindrical body 40 (and the connecting bolt 37 surrounded by the cylinder 40) is inserted into the reinforcing pipe 32 of the crosspiece 12 at the same time. In a state where the small edge surface 12b of the crosspiece 12 is in contact with the bottom surface 24, the cylindrical body 40 advances to a position where the through hole 36 overlaps. As a result, the end side of the cylindrical body 40 exposed to the second recess 21 side that is in contact with the column 11 is always completely surrounded from the outside by the second bellows 42, the reinforcing pipe 32 of the crosspiece 12 and the bottom surface 24. Will be. Since the first bellows 41 is arranged between the reinforcing pipe 32 and the bottom surface 24 of the cross board 12 in a state where it is compressed and has an urging force, the urging force is released and compressed even if this interval is somewhat widened. The second bellows 42 extends by that amount, and the surrounding state of the cylindrical body 40 is maintained.
At this stage, as shown in FIGS. 1 to 3, a fixing bolt 45 as a restricting member temporarily fixed to the female screw 36 a of the through hole 36 in the insertion hole 43 is rotated and advanced, and the tip thereof is cylindrical. Make sure that the 40 bites firmly. As a result, the rear end B of the crosspiece 12 is held in a non-rotatable manner with respect to the cylindrical body 40 via the fixing bolt 45, and the cylindrical body 40 is pressed against the first bottom surface 23 of the column 11. Therefore, it does not rotate itself. Therefore, the rotation of the crosspiece 12 is more reliably prevented.

By configuring in this way, the following effects are exhibited in the first embodiment.
(1) The first and second bellows 41 and 42 (and the reinforcing pipe 32 and the support 11 of the rung 12 are fixed) at the same time that the rung 12 is fixed to the support 11 and the first and second receiving parts 30 and 31. Since the bottom surfaces 23 and 24) of the connecting bolt 37 always surround the front side of the connecting bolt 37 and the end side of the cylindrical body 40 that is in contact with the column 11 in a hermetically sealed manner, the crossbar 12 and the column 11 are used in the pseudo-tree fence 15 over time. Even if this gap is left, it is difficult for rainwater or the like to reach the connecting bolt 37 and the reinforcing pipe 32, so that the rust of these metal members is prevented. Since the bellows 41 and 42 are always in a biased state, the bellows 41 and 42 follow even if the gap between the crosspiece 12 and the column 11 becomes large, so that the sealed state is maintained.
(2) The first and second bellows 41 and 42 are disposed in a slightly forcibly fitted shape in the first and second accommodating portions 30 and 31 having a diameter increased in a tapered shape. The bellows 41 and 42 are in close contact with the housing portions 30 and 31. Therefore, even if rainwater or the like enters, it is difficult to flow in the direction of the reinforcing pipe 32.
(3) The first and second accommodating portions 30 and 31 are penetrated into the first and second accommodating portions 30 and 31 because the diameters of the first and second accommodating portions 30 and 31 are increased in a tapered shape toward the direction of the facets 12a and 12b, respectively. The rainwater or the like is discharged from the taper portion closer to the lower side to the outside.
(4) Since the rear end portion B side of the crosspiece 12 is covered with the second bellows 42 from the outside of the cylindrical body 40, the rainwater and the like are connected from the second accommodating portion 31 side even if rainwater or the like enters. It is difficult to reach the bolt 37 and the reinforcing pipe 32.

(Embodiment 2)
In the second embodiment, only the configuration different from the first embodiment will be mainly described. In the following drawings, the same members as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.
As shown in FIG. 7, a groove 47 is formed in a ring shape at the base position of the first accommodating portion 30 (and / or the second accommodating portion 31) of the crosspiece 12 and outside the end portion of the reinforcing pipe 32. The base portion of the bellows 41 (only the first bellows 41 is shown but the same applies to the second bellows 41) may be fitted into the groove 47. In the fitted state, the base portion of the bellows 41 is disposed on the back side of the column side end surface 32a position of the reinforcing pipe 32.
If comprised in this way, in addition to the effect of the said Embodiment 1, rainwater etc. will become more difficult to penetrate | invade to the reinforcement pipe 32 direction.
(Embodiment 3)
The second embodiment is a variation of the second embodiment. In the following drawings, the same members as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.
As shown in FIG. 8, the wall surface in the first housing portion 30 (and / or the second housing portion 31) above the connecting bolt 37 is not tapered and is a surface parallel to the axial direction. is there.
With such a configuration, the rainwater and the like that have entered can be prevented from flowing in the direction of the reinforcing pipe 32.
Although the connection bolt 37 is used as a reference here, it is only necessary to prevent the infiltrated rainwater or the like from flowing in the direction of the reinforcing pipe 32, and therefore the region where the taper is formed can be changed as appropriate.

It should be noted that the present invention can be modified and embodied as follows.
In the above embodiment, the first and second bellows 41 and 42 in the above embodiments are made of chloroprene rubber. However, the present invention is not limited to this as long as it is a material that can be compressed to have a biasing force. .
