The present invention relates to the field of railings that are installed as safety facilities on stairs or porches of buildings, and more particularly, when the handle pipes are to be inclined at an angle to the prop pipe, the angle of change of the inclination angle of the handle pipes is changed. It relates to a handrail handle pipe connection for smooth handling.

In general, a railing is a safety facility installed in a staircase or a veranda of various buildings, and includes a prop pipe fixed to a bottom surface and a handle pipe connected to an upper end of the prop pipe. While the prop pipe is kept vertical, the handle pipe is inclined, and in the handrail installed on the porch of the building, the prop pipe is kept vertical and the handle pipe is horizontal.

As described above, when connecting the handle pipe to the prop pipe, a connection device is required regardless of whether the connection is inclined or horizontal.

First, let's look at the conventional pipe holding device of the handrail.

Specifically, a curved portion 2 having the same circular curvature as the ornament is formed in the spherical ornament 1 fixed to the upper end of the support pipe, and the through hole 3 is formed at the center of the side where the curved portion is formed. ) Is a structure in which the handle pipe is fitted into the fixed tube 4 is fixed to the decorative tube 4 is fixed to the decorative tool (1), the bent portion (2) is formed in the fixed tube 4 is the fixed tube (4) Is fixed to the outer circumferential surface of the ornament (1) so that the contact occurs at the same time at the front circumference irrespective of the fixed position so that the fixed state is very stable, and through the through-hole (4) 3) is formed to allow welding through the through hole (3) when fixing the fixing tube (4) to the ornament (1).

The handle pipe connection device of the handrail according to the conventional embodiment of such a structure is a fixed pipe 4 for fitting the handle pipe is a structure that is welded fixed to the ornament 1, the fixed tube fixed to the first ornament (1) Since the position of 4) is not changed after being fixed once, when the handle pipe is connected to the holding pipe, the inclination angle of the handle pipe shows a certain difference for each building. In the fixed state of (1), it cannot be used as a railing component of other buildings. Therefore, the generalization of parts was not possible. Therefore, it was very difficult for a company constructing a small building to purchase exactly the right parts. In the construction company to handle the construction of the stair railings of the building Since the angle of inclination of the pipe must be set in advance to inform the manufacturer of the railing, there is a problem that is very inconvenient in the work. There is a problem unsightly in the aesthetic view because the welding site remains dark browned.

On the other hand, it is to provide a holding pipe connecting device according to another embodiment as shown in Figures 3 to 4 attached to solve the problems of the conventional embodiment, domestic utility model registration No. 104954.

Specifically, the bolt hole 12 is formed in the spherical ornament 11 fixed to the upper end of the prop pipe, and the same central axis as the bolt hole 12 is formed in the ornament 11. The nut 13 is welded and fixed, and the curved contact portion 14 having the same circular curvature as the circular curvature of the ornament 11 in the bolt hole 12 forming portion of the outer peripheral surface of the ornament 11. ) And a fixed tube 16 having a long bolt insertion hole 15 is fixed to the curved contact part by tightening the bolt 17 to the nut 13, and the fixed tube 16 has a diameter greater than that of the fixed tube. The socket tube 19 is coupled to the freely rotated relative to the fixed tube 16 in the state having the coupling hole 18 of a smaller diameter, the handle pipe is fitted into the socket tube, the curved surface on the fixed tube 16 The contact portion 14 is formed in the outer peripheral surface of the decorative tube (16) When the bolt 17 is fixed, the contact is made at the front circumference at the same time irrespective of the fixing position, so that the fixed state is very stable, and the bolt insertion hole 15 of the long hole in the fixing tube 16 is provided. This is formed so that when the fixing tube 16 is fixed to the ornament 11 as a bolt 17, the position movement is possible within the long hole length range of the bolt insertion hole 15.

Handrail pipe connecting device according to another embodiment of the structure of the conventional structure such as fixing the fixing pipe 16 for fitting the handle pipe to the ornament 11 as a bolt 17, the fixing pipe 11 can be freely rotated Since the socket tube 19 is coupled to the structure, the problem of the conventional exemplary embodiment is sufficiently solved, but the structure is very complicated, so that the expense of the connection of the handle pipe is increased, as well as the connection of the handle pipe. In order to work, it is necessary to weld and fix the nut 13 to have the same center axis as the bolt hole 12 in the ornament 11, there is a problem that the productivity is reduced due to the deterioration of workability.

In addition, one embodiment of the prior art is the same, but other embodiments must go through a welding process, so it is necessary to secure related equipment, and thus requires a skilled technician, and it is difficult to work alone. There was a problem of excessive cost.

The present invention has been devised to solve the above-mentioned problems, and when the handle pipe is connected to the holding pipe, the handle pipe is connected to the handle pipe by simplifying the structure while sufficiently accommodating the change in the inclination angle of the handle pipe according to the building. The purpose of this is to reduce the expenditure due to the cost and to contribute to the increase in productivity due to improved workability.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 5 to 7.

5 is an exploded perspective view showing the handle pipe connecting device of the present invention handrail, Figure 6 is a longitudinal cross-sectional view showing a state in which the handle pipe is connected by the handle pipe connection device of the present handrail, Figures 7a and 7c As a front view and a side view for explaining the use state of the device of the present invention, the present invention is a screw fastener 102 in the largest circumferential surface of the spherical ornament 101 fixed to the upper end of the prop pipe And a curved portion 103 having a circular curvature equal to the circular curvature of the ornament 101 and a center of the side where the curved portion is formed. 105 is in contact with the inner diameter portion of the fixed tube is inserted into the plate 107 is formed with a screw insertion hole 106 eccentrically to one side from the central axis (X) of the fixed tube 105, the decorative tool 101 formation Fastening screw 108 is screwed through the screw insertion hole 106 formed in the mill plate 107 and the through-hole 104 formed in the fixed tube 105 in the screw fastening hole 102 is a handle pipe to the fixed tube 105 It is fitted structure.

The process of connecting the handle pipe to the holding pipe by the handle pipe connection device of the present invention configured as described above is as follows.

The fixing tube 105 is brought into contact with the outer circumferential surface of the ornament 101 fixed to the upper end of the support pipe while wrapping the screw fastener 102 formed in the ornament.

Subsequently, insert the contact plate 107 in which the screw insertion hole 106 is formed eccentrically to one side from the axial center line of the fixing tube to the inner diameter of the fixing tube 105, and then move the fixing tube 105 to position the screw insertion hole. And the through hole 104 formed in the screw insertion hole 106 and the fixed tube 105 formed from the outside of the fixed tube 105 in this state so that the 106 is aligned with the screw tightening hole 102. ) Through the tightening screw 108 through the screw tightening hole 102 formed in the ornament 101, the screw tightening the screw 108, but until this time the screw tightening of the screw is not in a complete state It is enough to be loose enough not to be separated from the ornament 101.

In this state, when the fixing tube 105 is rotated according to the horizontal state or the inclined state of the handle pipe to be connected later, the fixing tube contacts the ornament 101 of the fixing tube 105 as the fixing tube is eccentrically rotated about the axis. Since the position is changed, the central axis X of the fixing tube 105 is changed to a horizontal state or an inclined state according to the changed position of the contacting device 101 of the fixing tube 105, and then the changed central axis of the fixing tube 105 is changed. When the worker's intention is in accordance with the tightening screw 108 is completely tightened so that the fixing tube 105 is tightly fixed to the ornament 101, while the tightening screw 108 is completely tightened in the state that the plate 107 is tightened Since the contact portion 101 of the fixing tube 105 is strongly pushed toward the decorative unit, it is understood that the fixing tube 105 is fixed while being closely adhered to the decorative unit 101.

The plate 107 is inserted into the inner diameter of the fixing tube 105 to strongly push the fixing tube 105 toward the ornament 101 by the complete tightening of the tightening screw 108 is the shape of the curvature 101 of the fixture 101 It is preferable that the curved plate has the same curvature direction as that when the plate 107 is pushed strongly by the fixing tube 105 toward the ornament 101 by the complete tightening of the fastening screw 108. In order not to interfere with the outer circumferential surface of the sphere 101 to prevent interference, as well as a tight plate 107 in the state that the tightening screw 108 is completely tightened the fixing tube 105 toward the ornament 101 When pushing, it also has its own cushioning force to contribute to the improvement of fixing force.

Then, when connecting the handle pipe according to the present invention will be described with an embodiment when the handle pipe is in a horizontal state and the inclined state.

The center of the fixing tube 105 is on the largest circumferential surface of the decoration 101 as shown in FIG. 7A with the fixing tube 105 fixed to the ornament 101 by complete tightening of the tightening screw 108. In the case that is located in the spherical shape and the central screw tightening screw 108 is always present on the largest circumferential surface of the decorative tool 101, considering that the central axis of the fixed tube 105 (X) 7) becomes horizontal, and as shown in FIG. 7B, when the center of the fixing tube 105 is located as far as possible above the largest circumferential surface of the ornament 101, the ornament is spherical and the center of the ornament. Given that the tightening screw 108, which is an axis, is always present on the largest circumferential surface of the ornament 101, the center axis X of the fixation tube 105 is ultimately inclined upwardly as shown in FIG. 7C. As shown, the center of the fixing tube 105 is the In the case of being positioned as far below the large circumferential surface as possible, the fastener 105 is always spherical and the fastening screw 108, which is the central axis, is always present on the largest circumferential surface of the ornament 101. The central axis X of X) is inclined downward as much as possible.

Of course, depending on how much the eccentric rotation of the fixing tube 105, the inclination angle of the central axis (X) when the fixing tube is fixed to the decorative tool 101 will vary.

In this way, after fixing the fixing tube 105 to the ornament 101 in a state in which the central axis (X) is in a horizontal state or inclined by an arbitrary angle, when the handle pipe is fitted to the fixing tube 105, The handle pipe is also the same as the center axis (X) of the fixed tube 105, or is connected to the holding pipe in a state inclined by an arbitrary angle is to serve as a railing.

The curved portion 103 formed in the fixed tube 105 in the present invention component has the same circular curvature as the circular curvature of the ornament 101, which is independent of the position of the fixing tube 105 In the state in which the fixing is completed at 101), the curved portion 103 causes the contact to occur at the same time around the entire portion, so that the state in which the fixing is completed is very stable, which is the same as already described in the conventional and other embodiments. Do.

On the other hand, the connection work of the handle pipe of the present invention may be performed while fixing the fixing pipe 105 to the decoration in the state of fixing the ornament 101 to the top of the holding pipe first, as described in the above-described embodiment While fixing the decorative tube 105 to the ornament in the state that does not fix the ornament 101 on the top of the pipe first, and then fixing the ornament to the holding pipe while changing the position of the ornament 101 Can be understood.

Therefore, the present invention is that the fixing pipe 105 for fitting the handle pipe is tightened by the tightening screw 108 in a state capable of eccentric rotation to the ornament 101, all the problems caused by welding and fixing the conventional fixation tube to the ornament. Naturally, the first structurally very simple solution reduces cost expenditures due to the connection of the handle pipe, as well as increases the productivity by reducing the connection time, and secondly, when connecting the handle pipe in an inclined state. The inclination angle can be finely adjusted in various forms according to the eccentric rotation angle of the fixed tube 105, so that it can be applied in various forms to the handrails of various buildings. Even beginners can work without difficulty because they do not need There is also the effect that the entire operation costs, including rain.
