Raise-type handrail structure and system

Technical field

[0001] The present invention relates to a flip-up handrail structure and system, and more particularly, a handrail structure and system that can be installed on an inclined land, and a flip-up handrail structure in which a part of the handrail can be raised. And the system.

Background art

[0002] Conventionally, handrails have been installed on walls such as stairs and corridors to assist walking when elderly people or rehabilitated people walk in the house.

However, if there is a window or doorway in the middle, handrails cannot be permanently installed at that part, so the handrails will break off at that location. There is no problem for healthy people, and even for distances, elderly people and those who are rehabilitating are not such handrails. It may lead to a fall accident.

Therefore, even if there is a window or doorway in the middle, a part of the handrail can be rotated around its one end to form a continuous handrail when elderly or rehabilitated people walk. On the other hand, a flip-up type handrail has been proposed that allows a part of the handrail to stand upright when using a window or an entrance / exit.

As such a flip-up type handrail, there are, for example, Japanese Patent Laid-Open No. 2000-93227 (Patent Document 1) and Japanese Patent Laid-Open No. 11-236755 (Patent Document 2).

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the flip-up type handrail structure and system according to the present invention will be described in more detail based on a preferred embodiment shown in the drawings. FIG. 1 is a side view showing an embodiment of a flip-up handrail structure and system according to the present invention, and FIG. 2 is a side view showing a state in which a handrail member is flipped up and held in a vertical direction.

[0021] First, the illustrated flip-up system 1 is installed on a staircase that is a typical slope. A support column 3 is erected on the installation surface G1 located on the lower side in the inclination direction, and a support column 5 is erected on the installation surface G2 located on the upper side in the inclination direction. A support member 10 is attached to the column 3, and a connecting member 20 is attached to the column 5. The handrail member 30 is attached to the support member 10 in a state where the base end portion 31 thereof is rotatable, and the tip end portion 33 side opposite to the base end portion 31 of the handrail member 3 can be attached to and detached from the connecting member 20. It is designed to be connected and fixed. With the above-described configuration schematically shown, the handrail member 30 rotates about the base end 31 as a fulcrum, and can jump up to a vertical state as shown in FIG.

[0022] The support column 3 described above is erected via an anchor member 3a fixed to the installation surface G1 by a fastening fixture such as an anchor bolt (not shown). Similarly, the column 5 is erected via an anchor member 5 fixed to the installation surface G2 by a fastening fixture such as an anchor bolt (not shown). In addition, the installation method of the support | pillars 3 and 5 is not specifically limited, What is necessary is just to install by a normal means. Each of the support columns 3 and 5 is formed of a cylindrical metal pipe material, and the upper end of the support columns 3 and 5 is connected to a handrail that is movable in the vertical direction so that the inclination angle of the handrail members 3c and 5c can be adjusted. Members 3b and 5b are provided. Thus, the handrail members 3c and 5c can be attached in a state where the handrail connecting members 3b and 5b are adjusted so as to have an angle corresponding to the inclination of the stairs which is the installation location. In addition, the material of the support | pillars 3 and 5 is not restricted to a metal thing, A suitable material can be selected.

[0023] The support member 10 attached to the support post 3 includes a support bar 11 for attaching the base end portion 31 of the handrail member 30 in a rotatable state, and two upper and lower parts for attaching the support bar 11 to the support post 3. Joint metal fittings 13 and 13 are provided.

As shown in FIG. 3, the support bar 11 has an elongated plate shape as a whole, and the upper side thereof does not prevent the rotational movement on the base end portion 31 side of the handrail member 30 described later. In order to make it, it has a semi-circular shape. The upper portion of the support bar 11 is formed with a hollow portion 1 la hollowed out in a substantially circular shape, and an insertion portion l ib is formed so as to communicate with the hollow portion 1 la. As shown, a keyhole-shaped space is formed. This insertion portion 1 lb is installed so as to extend in a substantially vertical direction when attached to the column 3.

[0024] In addition, on the front and back surfaces of the support bar 11, vertically long groove portions l lc and 1 lc are formed along the longitudinal direction, respectively. The groove portions l lc and 11c are formed so that convex portions 13e provided on a clamping piece 13a (to be described later) of the joint fitting 13 come into close contact when the support bar 11 is attached to the support column 3 by the two joint fittings 13 and 13. As a result, the support bar 11 is firmly supported. The groove 11c is formed in a vertically long shape so that the mounting position of the joint fittings 13 and 13 can be adjusted, thereby adjusting the height position where the handrail member 30 should be arranged. The handrail member 30 and the handrails 3c and 5c can be installed in a straight line.

Further, on the lower side of the support bar 11, retaining protrusions 1 ld and l id are provided so that the force on both side surfaces protrudes. The retaining protrusions l ld and l id serve to prevent the lower joint fitting 13 from being easily displaced or dropped.

[0025] As shown in FIGS. 4 (a) and 4 (b), the joint fitting 13 sandwiches the support column 3 and the support bar 11. It has two pairs of sandwiching pieces 13a, 13a, and a bolt 13b and a nut 13c for fixing the supporting column 3 and the support bar 11 in a state where the pair of sandwiching pieces 13a, 13a are sandwiched. It is made. Recesses 13d for accommodating bolts 13b or nuts 13c are formed on the side surfaces of the sandwiching pieces 13a and 13a, respectively.

[0026] The inner side surface of the holding piece 13a on the side holding the support column 3 is formed with a curved surface corresponding to the curvature of the support column 3. On the other hand, a convex portion 13e is formed on the inner surface of the sandwiching piece 13a on the side of sandwiching the support bar 11 so as to be fitted in the groove 1lc provided in the support bar 11, and thus the sandwiching piece 13a is formed. 13a and 13a are fixed to the support bar 11 so as to bite with force. The groove portion 11c is formed along the longitudinal direction of the support bar 11, and the support member 10 can be attached to the support column 3 at a desired height position within the range. It is as follows. In the flip-up system 1 shown in FIG. 1, two joint fittings 13 each including two pairs of sandwiching pieces 13a and 13a are used in the vertical direction. The support bar 11 is fixed by the two joint brackets 13 and 13 in order to securely fix the support bar 3 to the support column 3, and one or two or more can be used. Here, FIG. 5 (a) shows an embodiment of the joint fitting used when the support bar 11 is fixed with one joint fitting. For ease of understanding, the same reference numerals are used for similar components. The joint fitting 13 shown in FIG. 5 (a) includes a holding piece 13a shaped like a vertically long holding piece 13a shown in FIG. 4 (b), and a bolt 13b or Two recesses 13d for accommodating the nut 13c are provided on the top and the bottom. The other parts are almost the same as those of the joint fitting 13 shown in FIGS. 4 (a) and 4 (b), and a description thereof will be omitted. FIG. 5 (b) shows a flip-up system 1 according to an embodiment using the joint fitting 13 shown in FIG. 5 (a).

On the other hand, as shown in FIGS. 6 (a)-(c), the proximal end 31 side of the handrail member 30 is closer to the diameter of the substantially circular gap 11a provided on the upper side of the support bar 11. An insertion piece 35 is provided that is slightly small and is sized to be inserted into the insertion portion l ib. The handrail member 30 is held in this state when the handrail member 30 is erected in a substantially vertical direction by the insertion piece 35 and the keyhole-shaped space portion formed by the gap portion 11a and the insertion portion rib. A holding means is formed. That is, when the insertion piece 35 of the handrail member 30 is positioned in the substantially circular gap 11a, the length of the insertion piece 35 is slightly smaller than the diameter of the gap 11a. It is possible to freely rotate within the portion 11a, and thereby the handrail member 30 can be rotated around the base end portion 31 to perform a flip-up operation.

Then, when the handrail member 30 is set in a vertical state, the insertion piece 35 is easily inserted by its own weight into the insertion portion ib provided in communication with the gap portion 11a. In this state, since the free rotation of the handrail member 30 is prevented, the handrail member 30 is held in a vertically standing state. Furthermore, if the handrail member 30 is lifted and the insertion piece 35 is moved to the position of the gap 11a, it can be freely rotated again and returned to the original inclined state.

[0028] According to the configuration as described above, the insertion piece 35 is inserted into the insertion portion l ib only when the handrail member 30 is in a vertically upright state. The member 30 can always be held in a vertical position, which is a special advantage! That is, as shown in FIG. 1, the base end portion 31 of the handrail member 30 serving as a pivot point for the flip-up operation is, of course, provided on the column 3 disposed below the inclination. As shown in Fig. 7, the base end 31 of the handrail member 30 serving as a pivot point of rotation can be provided on the support column 3 arranged on the upper side with respect to the inclination, and even in this case, the handrail member 30 stands upright. Can be held in a state. This reduces installation restrictions and enables flexible installation on a variety of inclined surfaces. Not only the inclined surface but also the installation surface G1 and the installation surface G2 are on the same horizontal plane, and the handrail member 30 can be installed in a horizontal state, as shown in FIG. .

Next, the connecting member 20 attached to the support 5 will be described. The connecting member 20 has substantially the same configuration as that of the supporting member 10, and is roughly a chucking bar 2 1 to which a lock mechanism 40, which will be described later, provided on the distal end portion 33 side of the handrail member 30 is detachably connected and fixed. And joint brackets 13 and 13 for attaching the chucking bar 21 to the column 5.

[0030] As shown in FIGS. 9 (a)-(c), the chucking bar 21 has an elongated plate shape as a whole, and its upper side is formed in a mountain shape, and further from its upper part. The protruding bar 21b is thinner than the chucking bar 21 and has a protruding piece 21b. . A cylindrical protrusion 21a is formed on the protruding piece 21b. The columnar protrusion 21a is detachably connected and fixed to a lock mechanism 40 described later provided on the distal end 33 side of the handrail member 30. In other words, the protruding portion 21 a is disposed in the vicinity of the distal end portion of the connecting member 20. The protrusion 21b having a thickness thinner than the chucking bar 21 is provided because the opening width of the opening 49 (see FIG. 10) for guiding the protrusion 21b to the lock mechanism 40 built in the front end 33 of the handrail member 30 is set. This is to make it as narrow as possible.

[0031] The inclination angles of the left and right slopes 21e, 21e on the upper side of the chucking bar 21 that is cut into a mountain shape do not contact the handrail member 30 when it is connected to the chucking bar 21, so that the connection is not hindered. Is set corresponding to the maximum inclination at which the handrail member 30 is installed.

[0032] Like the support bar 11, the front and back surfaces of the chucking bar 21 are respectively formed with longitudinal grooves 21c and 21c along the longitudinal direction, and the lower side of the chucking bar 21 has both sides thereof. The retaining protrusions 21d and 21d are provided so that the surface force also protrudes. Since the functions of the grooves 21c and 21c and the retaining protrusions 21d and 21d are the same as those of the support bar 11, the description thereof is omitted here.

On the other hand, as shown in FIG. 10, a lock mechanism 40 is detachably connected to and fixed to a cylindrical protrusion 21a provided on the upper side of the chucking bar 21 on the tip 33 side of the handrail member 30. Is provided.

The lock mechanism 40 generally includes a lock piece 41 locked to the substantially cylindrical protrusion 21a of the chucking bar 21, a panel member 47 for urging the lock piece 41, and the lock piece 41 and the protrusion 21a. The release button 43 is a release mechanism for releasing the locked state, and these are housed inside the front end portion 33 of the handrail member 30. An opening 49 for guiding the protrusion 21 a provided on the chucking bar 21 to the lock mechanism 40 is formed on the tip 33 side of the handrail member 30. The opening 49 is formed in a slit shape having an opening width that can receive the protrusion 21a.

[0034] As shown in FIG. 11, the lock piece 41 is provided with a sliding surface 41a which is an inclined surface having an acute angle so as to contact and slide on the protrusion 21a. An engaging portion 41b that engages with the protruding portion 2la is formed at the end. In addition, on the upper side of the lock piece 41, a pin 45 ( Holes 41e and 41e are provided through which the holes are inserted (see FIG. 10). The lock piece 41 is formed with a panel member accommodating portion 41 d for accommodating a panel member 47 for urging the lock piece 41. Furthermore, the panel member 47 is provided with a release surface 41c, which is an acutely inclined surface on which a release bar 43a is brought into contact and slides, which is provided with a release button 43 that releases the locked state of the lock piece 41 and the protrusion 21a. A thin rod-shaped material made of metal is bent, and a hollow space portion is formed in the bent portion so as to be inserted through the pin 45. The pin 45 is passed through the space portion and placed in the panel member housing portion 41d. ing. As a result, the lock piece 41 is urged in the X direction shown in FIG.

Here, the movement until the lock piece 41 is locked to the protrusion 21a will be described with reference to FIGS. 12 (a) to 12 (c). FIGS. 12 (a) to 12 (c) are explanatory views showing the relationship between the locking piece 41 and the protrusion 21a and the side force.

First, the handrail member 30 is rotated by using the base end portion 31 of the handrail member 30 as a fulcrum, and the lock mechanism 40 provided at the distal end portion 33 is brought close to the connecting member 20 (FIG. 12 (a)). Then, when the handrail member 30 is further lowered and the tip of the chucking bar 21 is inserted into the opening 49, the sliding surface 41a of the lock piece 41 contacts the protrusion 21a and slides on the surface thereof. At this time, as shown in FIG. 12 (b), due to the protruding height of the cylindrical protruding piece 21b, the lock piece 41 opposes the biasing force of the spring member 47 and is in the opposite direction (the opposite direction to the X direction). ) And rocks with pin 45 as a fulcrum. When the handrail member 30 is further lowered, the protruding portion 21a passes through the edge of the sliding surface 41a, the lock piece 41 is pushed back in the X direction again by the biasing force of the panel member 47, and the protruding piece 21b is locked. It is locked to 41b (FIG. 12 (c)). By such an operation, the handrail member 30 is connected and fixed to the connecting member 20.

[0036] Further, since the projection 21a for locking the lock piece 41 has a cylindrical shape, it can be reliably locked even if the installation angle of the handrail member 30 is slightly changed. That is, as shown in FIG. 14, when the base end portion 31 of the handrail member 30 serving as a pivot point for the flip-up operation is arranged on the lower side with respect to the inclination, the connecting operation from the A direction is performed. When the base end 31 of the handrail member 30 that serves as the pivot point of the pivot is arranged on the upper side with respect to the inclination, the connecting operation is performed from the B direction, and the lock is activated by any directional force. It is possible. [0037] The release button 43 that releases the locked state of the lock piece 41 and the protrusion 21a includes the release bar 43a described above and a panel member 43b that urges the release button 43 downward. The In a normal state, the release button 43 is urged downward by the panel member 43b, so that the release bar 43a does not hinder the urging of the lock piece 41 by the panel member 47. On the other hand, when the release button 43 is pushed in, the release bar 43a contacts and presses the release surface 41c, and the lock piece 41 is shown in FIG. 10 against the biasing force of the panel member 47 that biases the lock piece 41. Swing in the direction opposite to the direction. As a result, the locked state with the locking portion 41b locked to the protruding portion 21a is released, and the handrail member 30 can be flipped up with its base end portion 31 as a fulcrum. FIGS. 13 (a) and 13 (b) show how the handrail member 30 and the connecting member 20 are attached and detached.

[0038] The installation angle of the handrail member 30 is as described above that it is possible to continuously respond to an acute angle force and an obtuse angle according to the inclination of the installation location. The mounting angle can also be continuously adapted as appropriate according to the situation of the installation location. That is, by appropriately selecting the mounting angle of the joint brackets 13 and 13 of the support member 10 to the column 3 and appropriately selecting the mounting angle of the joint brackets 13 and 13 of the connecting member 20 to the column 5 (FIG. a) — Various installation conditions as shown in (c) can be created. Therefore, since the inclination angle and horizontal angle of the handrail member 30 can be freely selected, it is possible to install the handrail regardless of the installation location. For example, it can be easily installed on slopes where the slope of the slope changes irregularly and the force and the angle of the curve are not constant.
