[Background]
[0002]
  2. Description of the Related Art Conventionally, handrails have been installed on walls such as stairs and corridors in order to assist walking when elderly people or rehabilitated people walk in a house.
  However, if there is a window, doorway, or the like in the middle, a handrail cannot be permanently installed at that portion, and the handrail will be interrupted at that location. Even if there is no problem for healthy people, a little distance without such a handrail is very uneasy for elderly people and those who are rehabilitating, and it takes time to pass, and it actually leads to a fall accident There is.
  Therefore, even if there is a window or doorway in the middle, a part of the handrail can be rotated with its one end as a fulcrum to form a continuous handrail when elderly or rehabilitated people walk On the other hand, a flip-up type handrail capable of vertically standing a part of the handrail when using a window, a doorway or the like has been proposed.
  Examples of such flip-up type handrails include Japanese Patent Application Laid-Open No. 2000-93227 (Patent Document 1) and Japanese Patent Application Laid-Open No. 11-236755 (Patent Document 2).

DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[0004]
  However, since the conventional flip-up type handrail is a type in which a bracket for supporting the handrail is attached to the wall surface and installed, it is necessary to have a wall surface at the installation location in order to install it outdoors. However, there is a problem that the installation location is greatly restricted. On the other hand, the fourth embodiment disclosed in Patent Document 2 is a type in which a bracket is attached to a support column erected on the floor surface and does not require a wall surface, but an upper portion for holding a raised handrail. Since the support portion is provided on the ceiling surface, this also has a problem that it cannot be installed outdoors.
[0005]
  In addition, since the conventional flip-up type handrail was supposed to be installed horizontally in the house, the flip-up angle of the movable part serving as the fulcrum of the flip-up is relative to the horizontal direction, which is the installation direction of the handrail It was comprised so that it might become substantially 90 degrees. For this reason, when this is installed on an inclined ground as it is, if the movable part is provided on a support column arranged on the upper side with respect to the inclination, even if the handrail is flipped up and bent by 90 °, it does not reach the vertical direction and is in a state of being lifted up. I can't hold it. Therefore, there has been a restriction that the movable portion serving as a fulcrum for flipping up must always be provided on the support column disposed below the inclination.
[0006]
  Furthermore, in the first embodiment disclosed in Patent Document 2, a bracket that supports the front end side of the handrail that can be flipped up in a horizontal state is fastened by a single bolt, and the bolt is The axis of rotation is the direction. That is, the bracket can adjust the arrangement angle of the handrail in the horizontal direction. However, in such a configuration, there is a possibility that the bolt loosens due to the attachment / detachment operation of the tip end portion to / from the bracket repeatedly, and the tip end portion of the handrail cannot be reliably accommodated. Further, as described above, when the handrail is installed with an inclination, the tip end side of the handrail that can be flipped up cannot be reliably accommodated in the bracket.
[0007]
  Therefore, the present invention solves such conventional problems and raises the handrail structure that can be installed outdoors.MakeThe purpose is to provide.
  Further, according to the present invention, when installing on a slope such as a staircase or a hill, a movable part serving as a fulcrum for raising is provided on either side of the support column disposed on the upper side or the support column disposed on the lower side with respect to the inclination. Can be raisedMakeThe purpose is to provide.
  Furthermore, the present invention provides a flip-up type handrail structure that can reliably hold and fix the tip side of the handrail that can be flipped up regardless of the installation angle of the handrail.MakeThe purpose is to provide.

BEST MODE FOR CARRYING OUT THE INVENTION
[0016]
  Hereinafter, the flip-up handrail structure according to the present invention.To makeFurther details will be described based on the illustrated preferred embodiment. FIG. 1 is a side view showing an embodiment of a flip-up handrail structure 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.
[0017]
  First, the flip-up type shownhandrail1 is installed on a staircase which is a typical slope. A column 3 is erected on the installation surface G1 located on the lower side in the tilt direction, and a column 5 is erected on the installation surface G2 located on the upper side in the tilt direction. A support member 10 is attached to the column 3, and a connecting member 20 is attached to the column 5. A handrail member 30 is attached to the support member 10 in a state where the base end portion 31 thereof is rotatable, and a distal end portion 33 side opposite to the base end portion 31 of the handrail member 3 is detachably connected to the connecting member 20. It is supposed to be fixed. With the above-described configuration schematically shown, the handrail member 30 is rotated about the base end portion 31 as a fulcrum and can be flipped up to a vertical state as shown in FIG.
[0018]
  The above-described support column 3 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 are vertically movable handrail couplings that can adjust the inclination angle with respect to the installation surface of the handrail members 3c and 5c. Members 3b and 5b are provided. Thereby, the handrail members 3c and 5c can be attached in a state in which the handrail connecting members 3b and 5b are adjusted so as to have an angle corresponding to the inclination of the staircase that 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.
[0019]
  The support member 10 attached to the column 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 joint fittings 13 for attaching the support bar 11 to the column 3; 13.
  As shown in FIG. 3, the support bar 11 has an elongated plate shape as a whole, and the upper side of the support bar 11 does not prevent the rotational movement on the base end portion 31 side of the handrail member 30 described later. Therefore, it has a substantially semicircular shape. A space 11a hollowed out in a substantially circular shape is formed on the upper side of the support bar 11, and an insertion portion 11b is formed so as to communicate with the space 11a. A space is formed. The insertion portion 11b is installed so as to extend in a substantially vertical direction when attached to the column 3.
[0020]
  In addition, longitudinal grooves 11c and 11c are formed on the front and back surfaces of the support bar 11 along the longitudinal direction. The groove portions 11c and 11c are formed so that a convex portion 13e provided on a sandwiching piece 13a (to be described later) of the joint metal fitting 13 is in close contact when the support bar 11 is attached to the support column 3 by the two joint metal fittings 13 and 13. As a result, the support bar 11 is firmly supported. Further, the groove 11c is formed in a vertically long shape so that the attachment position of the joint fittings 13 and 13 can be adjusted, and thereby the height position where the handrail member 30 should be arranged can be adjusted. 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 11 d and 11 d are provided so as to protrude from both side surfaces. The retaining protrusions 11d and 11d serve to prevent the lower joint fitting 13 from being easily displaced or dropped.
[0021]
  As shown in FIGS. 4 (a) and 4 (b), the joint fitting 13 includes two pairs of sandwiching pieces 13a and 13a that sandwich the support column 3 and the support bar 11, and the pair of sandwiching pieces 13a and 13a. It has a bolt 13b and a nut 13c for firmly fixing the support bar 11 in a sandwiched state. Recesses 13d for accommodating bolts 13b or nuts 13c are formed on the side surfaces of the sandwiching pieces 13a and 13a, respectively.
[0022]
  An inner side surface of the sandwiching piece 13 a on the side that sandwiches 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 into the groove portion 11c provided in the support bar 11, whereby the sandwiching pieces 13a and 13a are The support bar 11 is fixed so as to bite firmly. 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 composed of two pairs of sandwiching pieces 13 a and 13 a are used in the vertical direction. The support bar 11 is fixed by the two joint fittings 13 and 13 in order to securely fix the support bar 11 to the support column 3, and one or two or more can be used. Here, FIG. 5A shows an embodiment of a joint fitting used when the support bar 11 is fixed by one joint fitting. In addition, the same code | symbol was used about the same component for easy understanding. 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 generally the same as those of the joint fitting 13 shown in FIGS. 4 (a) and 4 (b), and the description thereof is omitted. FIG. 5B shows a flip-up type of the embodiment using the joint fitting 13 shown in FIG.handrail1 is shown.
[0023]
  On the other hand, as shown in FIGS. 6A to 6C, the proximal end portion 31 side of the handrail member 30 is slightly smaller than the diameter of the substantially circular gap portion 11 a provided on the upper side of the support bar 11. In addition, an insertion piece 35 formed in a size that can be inserted into the insertion portion 11b is provided. And the holding means which hold | maintains the handrail member 30 in the state when the handrail member 30 stands up in the substantially vertical direction by this insertion piece 35 and the keyhole-shaped space part formed of the space | gap part 11a and the insertion part 11b. Is formed.
  That is, when the insertion piece 35 of the handrail member 30 is located in the substantially circular gap portion 11a, the length of the insertion piece 35 is slightly smaller than the diameter of the gap portion 11a. It is possible to rotate freely within 11a, and thereby the handrail member 30 rotates about the base end portion 31 and can perform a flip-up operation.
When the handrail member 30 is set in the vertical state, the insertion piece 35 is easily inserted by its own weight into the insertion portion 11b 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.
[0024]
  According to the above configuration, since the insertion piece 35 is inserted into the insertion portion 11b only when the handrail member 30 is in a vertically upright state, the handrail member 30 must be installed regardless of the inclination angle to be installed. It can be held vertically, which is a notable 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 provided on the column 3 disposed on the lower side with respect to the inclination. As shown in FIG. 4, the base end portion 31 of the handrail member 30 serving as a fulcrum of rotation can be provided on the support column 3 arranged on the upper side with respect to the inclination. Can be held. Thereby, the restrictions in installation reduce and it becomes possible to install flexibly corresponding to various inclined surfaces. Needless to say, the installation surface G1 and the installation surface G2 are on the same horizontal plane and the handrail member 30 can be installed horizontally as shown in FIG.
[0025]
  Next, the connection member 20 attached to the support | pillar 5 is demonstrated. The connecting member 20 has substantially the same configuration as the support member 10, and as a general rule, a chucking bar 21 to which a lock mechanism 40, which will be described later, provided on the front end 33 side of the handrail member 30 is detachably connected and fixed. And joint metal fittings 13 and 13 for attaching the chucking bar 21 to the support column 5.
[0026]
  As shown in FIGS. 9 (a) to 9 (c), the chucking bar 21 has an elongated plate-like shape as a whole, and its upper side is formed in a mountain shape and further protrudes from the upper part. In this manner, the protruding piece 21b having a thickness smaller than that of the chucking bar 21 is formed. A columnar protrusion 21a is formed on the protruding piece 21b. The columnar protrusion 21a is detachably connected to and fixed by a lock mechanism 40 described later provided on the tip 33 side of the handrail member 30. That is, the protruding portion 21 a is disposed in the vicinity of the distal end portion of the connecting member 20. Protruding piece 21b thinner than chucking bar 21 is provided so that the opening width of opening 49 (see FIG. 10) for guiding protruding piece 21b to lock mechanism 40 built in tip 33 of handrail member 30 is increased. This is to make it as narrow as possible.
[0027]
  The inclination angles of the left and right slopes 21e and 21e on the upper side of the chucking bar 21 that are 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.
[0028]
  Similarly to the support bar 11, longitudinal grooves 21 c and 21 c are formed on the front and rear surfaces of the chucking bar 21 along the longitudinal direction, respectively. The protrusions 21d and 21d are provided so as to protrude from the protrusions 21d. 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.
[0029]
  On the other hand, as shown in FIG. 10, a lock mechanism 40 that is detachably connected and fixed to a columnar protrusion 21 a provided on the upper side of the chucking bar 21 is provided on the front end 33 side of the handrail member 30. ing.
  The lock mechanism 40 generally includes a lock piece 41 that is engaged with the substantially cylindrical protrusion 21a of the chucking bar 21, a spring member 47 that biases the lock piece 41, a lock piece 41, and a protrusion. A release button 43 that is a release mechanism for releasing the locked state of 21 a is configured, and these are housed inside the distal 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 has an opening width that can receive the protrusion 21a and is formed in a slit shape.
[0030]
  As shown in FIG. 11, the lock piece 41 is provided with a sliding surface 41a that is an inclined surface having an acute angle so as to slide in contact with the protrusion 21a, and is provided at the edge of the sliding surface 41a. A locking portion 41b that locks to the protruding portion 21a is formed. In addition, holes 41e and 41e through which pins 45 (see FIG. 10) attached to the interior of the front end portion 33 of the handrail member 30 are inserted are provided on the upper side of the lock piece 41. It has been. Further, the lock piece 41 is formed with a spring member accommodating portion 41d for accommodating a spring member 47 for biasing the lock piece 41. Further, a release surface 41c, which is an acute inclined surface on which a release bar 43a provided in the release button 43 for releasing the locked state of the lock piece 41 and the protruding portion 21a contacts and slides, is provided.
  The spring member 47 is formed by bending a thin metal rod-like material and forming a hollow space portion that is inserted through the pin 45 at the bent portion. The spring member 47 is accommodated in a state where the pin 45 is passed through the space portion. It arrange | positions in the part 41d. Thus, the lock piece 41 is urged in the X direction shown in FIG.
[0031]
  Here, with reference to FIGS. 12A to 12C, the movement until the lock piece 41 is locked to the protrusion 21a will be described. 12A to 12C are explanatory views showing the relationship between the lock piece 41 and the protrusion 21a from the side.
  First, the handrail member 30 is rotated by using the proximal 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. 12A). When the handrail member 30 is further lowered and the tip of the chucking bar 21 is guided into the opening 49, the sliding surface 41a of the lock piece 41 comes into contact with the protrusion 21a and slides on the surface thereof. At this time, as shown in FIG. 12 (b), the lock piece 41 opposes the urging force of the spring member 47 due to the protruding height of the columnar protruding piece 21b (the direction opposite to the X direction). Is swung about the 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 spring member 47, and the protruding piece 21b is moved to the locking portion 41b. It is locked (FIG. 12 (c)). By such an operation, the handrail member 30 is connected and fixed to the connecting member 20.
[0032]
  In addition, since the protrusion 21a that locks the lock piece 41 has a columnar shape, it can be reliably locked even if the installation angle of the handrail member 30 changes slightly. 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 is performed from the A direction. When the base end portion 31 of the handrail member 30 that is a pivot point of rotation is arranged on the upper side with respect to the inclination, the connecting operation is performed from the B direction, and the locking is possible from any direction. ing.
[0033]
  The release button 43 that releases the locked state of the lock piece 41 and the protruding portion 21a includes the release bar 43a described above and a spring member 43b that urges the release button 43 downward. In a normal state, the release button 43 is urged downward by the spring member 43 b, so that the release bar 43 a does not hinder the urging of the lock piece 41 by the spring member 47. On the other hand, when the release button 43 is pushed, the release bar 43a comes into contact with and presses the release surface 41c, and the lock piece 41 is pressed against the urging force of the spring member 47 that urges the lock piece 41 as shown in FIG. Swing in the direction opposite to the direction. Thereby, the latching state with the latching | locking part 41b latched by the projection part 21a is cancelled | released, and the handrail member 30 can be flipped up by using the base end part 31 as a fulcrum. FIGS. 13A and 13B show the attachment / detachment state of the handrail member 30 and the connecting member 20.
[0034]
  As described above, the installation angle of the handrail member 30 can be continuously dealt with from an acute angle to an obtuse angle according to the inclination of the installation location. Further, the mounting angle in the horizontal direction of the support member 10 and the connecting member 20 is also set. Depending on the situation of the installation location, it can be made to respond appropriately and continuously. That is, by appropriately selecting the attachment angle of the joint fittings 13 and 13 of the support member 10 to the support column 3 and appropriately selecting the attachment angle of the joint fittings 13 and 13 of the connecting member 20 to the support column 5 as shown in FIG. ) To (c), various installation states can be created. Therefore, since the inclination angle and the horizontal angle of the handrail member 30 can be freely selected, it is possible to install the handrail regardless of the installation location of the handrail. For example, it can be easily installed on slopes where the slope of the slope changes irregularly and the angle of the curve is not constant.
