Japanese Patent Laid-Open No. 2003-119988

However, since the structure shown in Patent Document 1 includes a support column that supports the tip of the terminal handrail member, there is a problem that the support column may be an obstacle to the stair user, or that the appearance is impaired. . For this reason, although the structure which does not provide this support | pillar can also be proposed, if this support | pillar is not provided, this terminal handrail member will be supported by the cantilever shape, and intensity | strength will fall remarkably.
The same problem applies to handrails attached to other than stairs.

  Therefore, the present invention does not require a support column that supports the tip of the handrail member, and an object thereof is to provide a handrail that is excellent in strength and does not increase the cost during construction.

  The present invention relates to a handrail comprising a main handrail member, a terminal handrail member connected to one end of the main handrail member via a handrail member connector, and a support column supporting the handrail member connector. Is connected to a supporting column connected to the column, an arm projecting from the column connecting unit in the direction in which the terminal handrail member is inserted, and a tip of the arm. The terminal handrail member is formed of a bending member formed by bending and / or bending a long member, and one end of the terminal handrail member is connected to the handrail member. The handrail is connected to a tool, and the other end of the terminal handrail member is connected to the terminal handrail member connecting portion of the coupling auxiliary member.

  Since the terminal handrail member of the present invention is not provided with a column at the tip of the terminal handrail member, the terminal handrail member does not obstruct the passage and is also preferable in terms of aesthetics. Further, the terminal handrail member is formed of a bending member, and one end and the other end of the bending member are both connected and fixed to the support column, so that the user applies a force to the terminal handrail member from above. However, the user can be supported stably and firmly. Here, since the other end of the terminal handrail member is fixed to the support via a connection auxiliary member as a separate member, it is not necessary to fix the other end directly to the support by welding or the like. Therefore, the time and labor required for assembly can be saved, and the construction cost can be reduced. In addition, since the terminal of the handrail of this invention is comprised by the bending and / or curved part of a terminal handrail member, it is hard to catch a user's sleeve.

  Further, the support column connection portion of the connection auxiliary member includes a through hole that opens in a standing direction of the support column, and is connected to the support column by inserting the support column into the through hole, and the terminal handrail member connection The structure includes an insertion hole that is open along the direction in which the terminal handrail member is inserted, and the other end of the terminal handrail member is inserted into the insertion hole so as to be connected to the terminal handrail member. The

  In such a configuration, even if force is applied from above to the terminal handrail member that has been pushed out, the inner peripheral surface of the insertion hole of the terminal handrail member connecting portion supports the other end of the terminal handrail member. Sufficient strength is secured against the force from above.

  The present invention is advantageous in that it does not easily disturb the user because a post is not provided at the tip of the terminal handrail member that has been pushed out. There is also an advantage that it is preferable in terms of beauty. Moreover, since the terminal handrail member is being fixed with respect to the support | pillar by the one end and the other end, there also exists an advantage with high intensity | strength.

The handrail 1 which concerns on this invention is demonstrated according to an accompanying drawing.
As shown in FIG. 1, the handrail 1 is provided on the side of the staircase S. FIG. 1 shows the appearance of the terminal on the lower end side of the handrail 1 arranged at the lowest position of the staircase S.

Further, the base end 3a of the terminal handrail member 3 is inserted into the lower socket 5b and fixed by a fixing means such as a screw (not shown). With this configuration, the handrail member connector 5 has a function of connecting the inclined handrail member 2 and the terminal handrail member 3 and can change the inclination angle of the inclined handrail member 2 with respect to the terminal handrail member 3. It also has a function to do.

  The terminal handrail member 3 is composed of a bending member 3A in which a round cylindrical long member is curved in a U shape, and the horizontal portion located at the lowest position of the staircase S with the curved portion 3c as the tip 11 side. It is extended along the floor surface F and constitutes the terminal of the handrail 1. As described above, the upper base end 3 a is connected to the lower end 2 a of the inclined handrail member 2 via the handrail member connector 5, and the lower end 3 b is fixed to the column 4. The manner of fixing the lower end 3b will be described in detail later.

  Further, the handrail member connector 5 is supported by the support column 4 via a rotating member 7 provided in the lower part thereof. The rotating member 7 has a function of tilting the handrail member connector 5 with respect to the column 4.

  Further, the support column 4 is erected vertically on the floor surface F, and the upper portion of the support column 4 includes an expansion / contraction portion 4a (see FIG. 2) that can expand and contract along the vertical direction. A well-known technique can be suitably employed for the expansion / contraction mechanism of the expansion / contraction part 4a. Further, a connection assisting member 10 is attached to the stretchable portion 4a. Since the connection assisting member 10 relates to the main part of the present invention, it will be described in detail later.

  In addition, a well-known technique is suitably employ | adopted for the rotation mechanism of the handrail member coupling tool 5 and the rotation member 7 mentioned above, and the expansion-contraction mechanism of the expansion-contraction part 4a, and detailed description is abbreviate | omitted.

Next, the connection auxiliary member 10 according to the main part of the present invention will be described.
As shown in FIGS. 3 to 5, the connection assisting member 10 includes a support column connecting portion 10A, a terminal handrail member connecting portion 10B, and an arm portion 10C that connects the support column connecting portion 10A and the terminal handrail member connecting portion 10B. And is a single member having a substantially L shape in side view.

  As shown in FIGS. 3 and 5, the support column connecting portion 10 </ b> A includes a through hole 12 that opens in a penetrating manner along the vertical direction, and has a cylindrical shape. The through-hole 12 has a substantially elliptical shape when viewed from the front, and its dimensional shape is set corresponding to the dimensional shape of the extendable portion 4 a of the support column 4.

  Further, an arm portion 10C protrudes downward from the side portion of the support column connecting portion 10A, and a terminal handrail member connecting portion 10B is formed at the tip of the arm portion 10C.

  As shown in FIGS. 3 and 4, the terminal handrail member connecting portion 10 </ b> B includes an insertion hole 13 having a circular shape when viewed from the front. The insertion hole 13 is horizontally oriented in the depth direction of the hole, and is divided into a central empty part 15 and an outer peripheral empty part 16 by an annular peripheral wall 14 provided on the inner bottom surface of the insertion hole 13. The dimensions of the insertion hole 13, the dimensions of the central empty portion 15 and the outer peripheral empty portion 16, and the wall height of the peripheral wall 14 are set in accordance with the outer diameter and shape of the end 3 b of the terminal handrail member 3. ing.

In such a configuration, as shown in FIGS. 2 and 3, the connection assisting member 10 has the through hole 12 inserted through the extendable portion 4 a and fixed by a screw k. Furthermore, the end 3b of the terminal handrail member 3 is inserted into the insertion hole 13 and fixed with screws k. The terminal handrail member connecting portion 10 </ b> B is configured such that the terminal handrail 3 b of the terminal handrail member 3 is inserted along the peripheral wall 14 and the end edge thereof is accommodated in the outer peripheral empty portion 16.
Thereby, the terminal handrail member 3 is fixed with the upper base end 3a (one end) and the lower end end 3b (the other end) both connected to the support column 4 while the upper edge is horizontal. Therefore, even if the stair user applies a shearing direction force to the terminal handrail member 3 from above, the stair user can be supported stably and firmly.

Next, the assembly procedure of the handrail 1 will be described.
First, the column 4 alone is erected on the floor surface F, the column connection part 10A of the coupling auxiliary member 10 is inserted into the expansion / contraction part 4a of the column 4, and the rotating member is inserted into the upper end opening of the expansion / contraction part 4a. 7 base end is inserted. At this time, the connecting auxiliary member 10 is oriented so that the arm portion 10C protrudes in the direction in which the terminal handrail member 3 is inserted. Then, the connection assisting member 10, the expansion / contraction part 4a, and the rotating member 7 are fixed with screws k. Further, the handrail member connector 5 is disposed at the upper end of the rotating member 7.

  Next, the lower end 2 a of the inclined handrail member 2 is connected to the upper socket 5 a of the handrail member connector 5. Further, the upper base end 3a of the terminal handrail member 3 is fixed to the lower socket 5b, and the lower end 3b is inserted into the terminal handrail member connecting portion 10B of the auxiliary connecting member 10 to be screwed. ,Connecting. In addition, in the procedure described so far, the height of the support | pillar 4, the inclination angle of the inclination handrail member 2, and the inclination angle of the terminal handrail member 3 can be finely adjusted suitably.

  The handrail 1 assembled by the above assembling procedure is not obstructed when the staircase S is used because a post is not provided at the tip 11 of the handrail 1 and is also preferable in terms of aesthetics. Moreover, since the terminal 3b of the terminal handrail member 3 is fixed to the support column 4 via the connection auxiliary member 10 as a separate member, it is not necessary to fix the terminal 3b directly to the support column 4 by welding or the like. Therefore, the time and labor required for assembly can be saved, and the construction cost can be reduced. Further, even if a force is applied from above to the terminal handrail member 3 that is inserted almost horizontally, the inner peripheral surface of the insertion hole 13 of the terminal handrail member connecting portion 10B supports the end 3b of the terminal handrail member 3. Therefore, sufficient strength is secured against the force from above. Further, since the tip 11 is curved, the sleeve of the stairs user is not easily caught.

By the way, another form is proposed.
As shown in FIG. 8a, it is good also as the terminal handrail member 23 provided with the bending part bent by substantially right angle. Further, as shown in FIG. 8b, a terminal handrail member 33 in which a curved portion and a bent portion bent at an acute angle are combined may be used.

  In addition, it is desirable that the handrail insertion length L from the central axis α of the support column 4 to the tip 11 in the terminal handrail members 3, 23, 33 is 150 mm to 300 mm. Within such a range, the handrail 1 with stable strength can be obtained.

  In addition, although the Example described so far has shown the terminal of the lower end side of the handrail 1 in the lowest position of the stairs S, of course, it is applicable also to the terminal of the upper end side in the uppermost position of the stairs S. Moreover, the said support | pillar 4 stood up vertically upward from the wall surface in side parts, such as stairs. Moreover, the handrail 1 of the present invention is not limited to a staircase but can be applied to a horizontal floor and a slope.
