Description

  The present invention is used when an elderly person or a person who needs care takes a standing posture or a sitting posture in order to facilitate a standing posture or a sitting posture in a space such as a toilet, an entrance, or a bathtub. The present invention relates to a handrail device.

  Support columns and handrail devices installed indoors are widely known as auxiliary tools to make it easier for elderly people and those who need care to take a standing posture or sitting posture in a space such as a toilet, entrance, or bathtub. ing. In addition, these handrail devices are a hindrance when elderly people and care recipients access toilets, entrances, bathtubs, etc. or when handrail devices are not used. It is desired to have a function of retreating by rotating in the horizontal direction or the vertical direction.

  For example, in Japanese Patent Application Laid-Open No. 2008-63760 (Patent Document 1) and Utility Model Registration No. 3137494 (Patent Document 2), a column portion is erected from a base portion installed on a floor surface, and the upper end of the column portion is Discloses a handrail device in which a contact portion that is in contact with the ceiling is formed, and a handrail extending in the horizontal direction from the support portion is attached to an intermediate portion of the support portion.

  Moreover, the handrail of the handrail device described in Patent Document 1 is fixed to the support column so as not to rotate, and the handrail of the handrail device described in Patent Document 2 rotates to the support unit. All the handrails are supported in a cantilever manner with respect to the column, although they are attached in a possible manner. For this reason, when elderly people or care recipients grab or hold a handrail and take a standing or sitting posture, if the bending moment acts only to tilt the support to the support that supports the handrail Therefore, a large torsional moment works so as to rotate the column.

  However, the handrail device of the type described in Patent Documents 1 and 2 has a contact portion that contacts the ceiling at the upper end of the support so that the support can be installed indoors without damaging the ceiling or floor surface. , A base portion that comes into contact with the floor surface is provided at the lower end of the column, and the column is fixed by stretching between the ceiling and the floor surface. For this reason, the handrail devices described in Patent Documents 1 and 2 generate a frictional force generated between the contact portion and the ceiling and a base portion and the floor surface with respect to a bending moment acting on the support column. Although it can be resisted to some extent by the frictional force, it cannot sufficiently resist the torsional moment acting on the support column, and there is a problem that the support column and the handrail rotate. Further, when the handrail device is fixed more strongly, there is a problem that the pressed ceiling is deformed.

  In other words, the abutting part and the base part that extend laterally from the column are fixed so as to be orthogonal to the column, so that when they rotate in the vertical direction, a frictional force is exerted and the column is prevented from overturning. Is done.

  However, when a force acts in the direction of twisting the strut (rotating the strut horizontally), the strut does not tilt so as to fall down, and between the abutting part and the ceiling and between the base part and the floor surface. Since the generated frictional force does not change, if the force for twisting the support exceeds the frictional force, the handrail attached to the support and the support is easily rotated. For this reason, the handrail device has a problem that it cannot sufficiently support or assist the movement of elderly people or care recipients who apply a twisting force to the column.

JP 2008-63760 A Utility Model Registration No. 3137494

  In view of this, the present invention makes it easier for an elderly person or a person who needs care to take a standing posture or a sitting posture in a space such as a toilet, an entrance, or a bathtub. Even if a moment is applied to the support via the handrail, the support will not be misaligned or the support will not be released. In particular, the support or the handrail will rotate, or the support will be released due to the rotation of the support. It is an object of the present invention to provide a handrail device that can firmly support a support column without deforming the ceiling and without deforming the ceiling.

  When examining the strength of the ceiling and side walls in spaces such as toilets, entrances, and bathtubs, the corners where the side walls and the ceiling intersect generally have the most concentrated strength members such as columns and braces that support the side walls, and cross beams that support the ceiling. Therefore, it was found that the strength was high. Therefore, as a result of earnest research on the method for fixing the column in a space such as a toilet, a front door, and a bathtub based on the above investigation results, the present inventors connected a horizontal beam near the upper end of the column that is erected on the floor surface. The side beams are provided with side wall abutting portions extending substantially horizontally along the side walls and capable of stretching near the corners of the opposite side walls. It has been found that it is the most effective in improving the strength, and the present invention has been completed.

  That is, according to the present invention, the lateral beam portion having the expansion / contraction means, and one end portion of the lateral beam portion extends laterally from the lateral beam portion, and abuts against one of the opposing two side walls. A first ceiling corner fixing portion having a first upper side wall abutting portion, and the other end portion of the horizontal beam portion extending laterally from the horizontal beam portion, and the other of the opposing side walls. A second ceiling corner fixing part having a second upper side wall abutting part abutting on the side wall, and a column part extending downward from the transverse beam part and standing on the floor surface. A handrail device is provided.

  The column part erected on the floor surface has a rod shape extending from the floor surface to the vicinity of the ceiling, so that the length (height) of the column part can be changed or between the floor surface and the ceiling. It is preferable that the support column is provided with an expansion / contraction means so that it can be stretched. In addition, an urging means such as a spring may be supplementarily attached to the support column or the expansion / contraction means so that the tensioned state by the support column can be maintained even when the support column is tilted. Thus, it is convenient for the user that the column portion has a rod shape since the column portion can be easily grasped from any direction when taking the standing posture or the sitting posture. In addition, when the support column has a bar shape, it is possible to reduce a feeling of pressure by the support column in a space such as a toilet, an entrance, or a bathtub.

  Moreover, the expansion-contraction means of a support | pillar part is not specifically limited, A well-known technique is employable. For example, the column portion is divided into an outer cylinder and an inner cylinder that is slidably inserted into the outer cylinder. The expansion / contraction means can be configured by providing a rotating portion that can be made to have a diameter. In the case of this configuration, by pulling out the inner cylinder from the outer cylinder, the column part is adjusted to a target length, or adjusted to a length suitable for bringing the upper end of the column part or the upper mounting part into contact with the ceiling. Then, the inner cylinder can be fixed with respect to the outer cylinder by rotating the rotating part in the direction of reducing the diameter of the insertion opening of the outer cylinder.

  Further, for example, the support means can be divided into a lower support part and an upper support part, and the upper end part region of the lower support part and the lower end part region of the upper support part are respectively provided with male screw grooves in opposite directions. It can also be configured by covering and forming a cylindrical rotating portion having a female screw groove that is threadedly engaged with the male screw groove in both end regions. In the case of this configuration, by rotating the rotating part screwed with the male thread groove of the lower support part and the upper support part in one direction, by separating or approaching the lower support part and the upper support part. The strut portion can be adjusted to a certain target length, or adjusted to a length suitable for abutting the upper end or upper mounting part of the strut portion to the ceiling, and can be fixed as it is.

  It is preferable that the support | pillar part is provided with the handrail part extended from the support | pillar part to the side and attached to a support | pillar part. The shape of the handrail portion is not particularly limited, but it is preferable that the handrail portion has a rod shape so that the user can easily grasp the handrail portion, or the user can easily hold the handrail portion. A narrow table shape may be formed so that The narrow table may be detachably attached to the bar-shaped handrail. When the handrail portion extends laterally from the column portion in a substantially horizontal direction, the user can easily take a standing posture or a sitting posture by pulling or holding the handrail portion.

  Further, it is preferable that the handrail portion is attached so as to be rotatable and fixed in a substantially horizontal direction with respect to the support column, or to be able to rotate (bounce up) and fix in a substantially vertical direction with respect to the support column. It is more preferable that the height is adjustable with respect to the support column. The turning and fixing means and the height adjusting means of the handrail part are not particularly limited, and a known technique can be adopted. For example, as a means for rotating and fixing the handrail portion, a cylindrical sleeve attached with a handrail portion is rotatably mounted on a support column portion provided with a plurality of locking holes in the circumferential direction of the outer peripheral surface. In the rotation position where the provided pin hole and the locking hole of the support column coincide, the locking pin can be inserted and removed from the outside. If the handrail part is flipped up or pivotally attached to the column part, the handrail is used when the elderly or care recipients access the toilet, entrance, bathtub, etc. or when the handrail device is not used. Since the part can be retracted, it does not get in the way.

  In addition, the handrail height adjusting means is configured such that, for example, a cylindrical sleeve provided with a handrail portion is slidably attached to a support column provided with a plurality of locking holes in the longitudinal direction of the outer peripheral surface. The locking pin can be inserted and removed from the outside at the slide position where the provided pin hole and the locking hole of the support column match. If the handrail part is attached to the column so that the height can be adjusted, the handrail part height can be adjusted according to the user's physique, making it easier to handle the handrail part. The safety of the user who uses the department is further improved.

  It is preferable that the column portion is erected on the floor surface via a base portion installed on the floor surface. As described above, in the present invention, it is preferable that the support column has a bar shape. Therefore, the lower end of the support column that comes into contact with the floor surface has a plate-like base or a support column having a larger area than the cross section of the support column. If the leg-like base portion extending radially from the base of the portion is provided, the column portion can be stably erected without damaging the floor surface. Moreover, it is preferable that the support | pillar part is being fixed to the base in the perpendicular direction, and may be directly fixed to the base by welding etc., or may be indirectly fixed to the base via a joint etc.

  The base portion includes a base plate installed on the floor surface, and a first floor surface having a first lower side wall abutting portion that extends from the floor surface and abuts against one of the two opposing side walls. A first floor surface corner fixing portion, comprising: a corner fixing portion; and a second floor surface corner fixing portion having a second lower side wall abutting portion in contact with the other side wall of the opposing side walls. It is preferable that the second floor surface corner fixing portion is attached to the base plate so that the distance between the first floor surface corner fixing portion and the second floor surface corner fixing portion can be adjusted.

  Since it is important to reduce steps on floors such as toilets, entrances, and bathtubs as much as possible, the first floor corner fixing part and the second floor corner fixing part attached to the base plate and the base plate are plate-shaped. It is preferable that a rigid steel plate, a lightweight panel having a honeycomb structure inside, a panel with ribs provided with streak-like irregularities by a press or the like can be used. In addition, a resin rubber or the like may be provided on the back surface of the base plate and the floor corner fixing portion to increase the frictional force with the floor surface, and the surface of the base plate and floor corner fixing portion. In order to improve the touch and appearance, resinous rubber and carpet fabric may be provided.

  The first floor surface corner fixing portion and / or the second floor surface corner fixing portion is slidably and fixedly attached to the base plate, for example, so that the first floor surface corner fixing portion and the second floor surface corner fixing portion are fixed. The distance between the parts can be adjusted. For example, either one of the base plate or the floor surface corner fixing portion is provided with a slit, the other floor surface corner fixing portion or the base plate is provided with a screw hole, and they are overlapped to attach a screw to one member. By screwing into the screw hole of the other member through the slit, the floor surface corner fixing portion can be slidably and fixedly attached to the base plate.

  Further, the means for adjusting the distance between the first floor surface corner fixing portion and the second floor surface corner fixing portion is not limited to the above-described configuration. The lower side wall abutting portion can be screwed back and forth by fixing the bolt shaft to the portion, and rotating the nut screwed to the bolt shaft and rotatably attached to the base plate. Known techniques can be employed.

  However, the first lower side wall abutting portion of the first floor surface corner fixing portion and the second lower side wall abutting portion of the second floor surface corner fixing portion both laterally run substantially horizontally along the side wall. It preferably has a plate shape or a bar shape extending to. When the first lower side wall abutting part and the second lower side wall abutting part extend in the lateral direction along the side wall, the first lower side wall abutting part is turned into one of the two opposing side walls. The second lower side wall abutting part is brought into abutment with the other side wall of the opposing side walls, and the first floor surface corner fixing part and / or the second floor surface corner fixing part is used as a base. When secured to the plate, the base plate cannot physically rotate with respect to the opposing side walls. For this reason, the support | pillar part standingly installed so that it may adhere to a base plate, and the handrail part attached to this support | pillar part are prevented from rotating and twisting strongly via a base part.

  Next, the transverse beam part attached near the upper end of the support part, the first ceiling corner fixing part and the second ceiling corner fixing part attached to the end part of the transverse beam part will be described in detail.

  Near the upper end of the column part, the horizontal beam part is attached so as not to rotate around the column part. Further, in order to make the length of the horizontal beam portion variable or between the opposing side walls, the horizontal beam portion can be stretched through a first ceiling corner fixing portion and a second ceiling corner fixing portion described later. Has a telescopic means. Furthermore, even when the first ceiling corner fixing portion or the second ceiling corner fixing portion has moved from the abutting side wall, the horizontal beam portion or the expansion / contraction means is provided so that the stretched state by the horizontal beam portion can be maintained. The urging means such as a spring may be supplementarily incorporated. In addition, as long as the support | pillar part is being fixed to the cross beam part so that it may not rotate with respect to a cross beam part, you may join so that the attachment position with respect to a cross beam part can be changed.

  The expansion / contraction means of the cross beam portion is not particularly limited, and a known technique can be adopted. Similar to the expansion / contraction means of the support column, for example, the transverse beam is divided into a rod-shaped outer cylinder and a rod-shaped inner cylinder that is slidably inserted into the outer cylinder, and the outer cylinder is rotated around the outer periphery. Thus, the expansion / contraction means can be configured by providing a rotating part that can reduce or increase the diameter of the insertion opening of the outer cylinder. In the case of this configuration, a length suitable for bringing the first ceiling corner fixing portion and the second ceiling corner fixing portion attached to the end portion of the cross beam portion into contact with the side wall by pulling out the inner cylinder from the outer cylinder. After the adjustment, the inner cylinder can be fixed with respect to the outer cylinder by rotating the rotating part in the direction of reducing the diameter of the insertion opening of the outer cylinder.

  Further, the expansion / contraction means of the horizontal beam part is, for example, dividing the horizontal beam part into a first horizontal beam part and a second horizontal beam part, a second horizontal beam side end region of the first horizontal beam part, and a second horizontal beam part. A cylindrical rotating part having external thread grooves opposite to each other in the first lateral beam side end area and having female thread grooves threaded into the male thread grooves in the both end area regions is provided. It can also be configured by doing. In the case of this configuration, the first transverse beam portion and the second transverse beam portion are separated from each other by rotating the rotating portion screwed with the male thread groove of the first transverse beam portion and the second transverse beam portion in one direction. The first ceiling corner fixing portion and the second ceiling corner fixing portion attached to the end portion of the cross beam portion are adjusted to a length suitable for contacting the side wall, Can be fixed.

  In addition, when the horizontal beam portion is not rotated about the support column portion via a T-shaped cylindrical joint or the like, but is indirectly attached so as to be slidable in the axial direction of the horizontal beam portion, Since the part can pass through the T-shaped cylindrical joint and the entire length can be changed, if the expansion / contraction means is provided at one place on the cross beam part, the cross beam part is between the opposing side walls. The length can be adjusted so as to stretch through the first ceiling corner fixing portion and the second ceiling corner fixing portion.

  On the other hand, when the horizontal beam portion is directly attached so that the horizontal beam portion does not rotate around the column portion and does not slide in the axial direction of the horizontal beam portion by welding or the like, the horizontal beam portion is separated from the column portion. Since the length to the first or second ceiling corner fixing portion can only be adjusted individually, the expansion and contraction means must be provided in the horizontal beam portion with two or more positions on the horizontal beam portion across the connecting portion with the column portion. The length may be adjusted so as to stretch between the opposing side walls via the first ceiling corner fixing portion and the second ceiling corner fixing portion while the column portion is standing at an arbitrary position on the plane. become unable.

  In a plan view, the first ceiling corner fixing portion fixed to the cross beam portion so as not to change the connection angle with respect to the cross beam portion extends laterally from the cross beam portion at one end of the cross beam portion. In addition, it is preferable to have a first upper side wall abutting portion that abuts against one of the two opposing side walls. Similarly to the first ceiling corner fixing portion, the second ceiling corner fixing portion fixed to the horizontal beam portion so that the connection angle cannot be changed with respect to the horizontal beam portion in plan view is also other than the horizontal beam portion. It is preferable to have the 2nd upper side wall contact part which is extended to the side from the cross beam part in the edge part, and contact | abuts to the other side wall among two opposing side walls. If the first and second ceiling corner fixing parts are fixed to the cross beam part so that the connection angle cannot be changed with respect to the cross beam part, they are joined so that the mounting position with respect to the cross beam part can be changed. Also good.

  When the first upper side wall abutting part and the second upper side wall abutting part extend in the lateral direction along the side wall, the first upper side wall abutting part is moved to one of the two opposing side walls. The second upper side wall abutting part is brought into contact with the other side wall of the opposing side walls, and the first ceiling corner fixing part and / or the second ceiling corner fixing part is brought to the cross beam part. When fixed, the cross beam portion cannot physically rotate with respect to the opposite side wall.

  That is, the first and second upper side wall abutting portions extending laterally along the side wall from the cross beam portion are fixed to the horizontal beam portion in an angle invariable in the horizontal direction, so that the rotation in the horizontal direction is performed. Is restricted, and in particular, the horizontal beam portion is prevented from rotating in the horizontal direction.

  As a result, the column portion joined non-rotatably to the cross beam portion and the handrail portion attached to the post portion pass through the cross beam portion and the first and second upper side wall abutting portions joined to the cross beam portion. Therefore, the rotation and twisting are strongly prevented. Further, the first and second upper side wall abutting portions are brought into contact with the corner portion having a relatively high strength by concentrating strength members such as columns and braces supporting the side walls and cross beams supporting the ceiling. The installation strength is higher than that of the conventional handrail device that fixes the column using the vicinity of the center or the vicinity of the center of the ceiling, and the side wall and the ceiling are not deformed. In particular, the longer the extension length of the first upper side wall abutting part and the second upper side wall, the stronger the horizontal beam part and the column part can be prevented from rotating in the horizontal direction. it can.

  The first ceiling corner fixing part preferably has a first ceiling contact part that contacts the ceiling extending from one side wall, and the second ceiling corner fixing part also has It is preferable to have the 2nd ceiling contact part contact | abutted to the ceiling extended from the other side wall. When the first ceiling corner fixing part and / or the second ceiling corner fixing part has the first ceiling abutting part and the second ceiling abutting part, the column part joined to the cross beam part is It becomes possible to stretch strongly between the floor surface and the ceiling via the horizontal beam portion and the first and second ceiling contact portions joined to the horizontal beam portion.

  That is, each of the first and second ceiling abutting portions extends laterally from the lateral beam portion along the ceiling, and is fixed to the lateral beam portion in an angle invariable in the vertical direction, so that it rotates in the vertical direction. Then, a frictional force works and the vertical rotation of the support column is strongly prevented.

  Moreover, said effect can be acquired also by attaching the auxiliary contact part contact | abutted to a ceiling to the upper end of a support | pillar part. In this case, the auxiliary contact portion preferably extends laterally along the ceiling from the joint portion with the cross beam portion, and is used in combination with the first ceiling contact portion and / or the second ceiling contact portion. Or may not be used together.

  Since the auxiliary contact part is fixed to the column part joined to the cross beam part in an angle-invariant manner in the vertical direction, it rotates in the vertical direction in the same manner as when the ceiling contact part is provided in the ceiling corner fixing part. Then, a frictional force works and the vertical rotation of the support column is strongly prevented.

  As a result, the column part joined non-rotatably to the cross beam part and the handrail part attached to the post part are passed through the cross beam part and the first and second ceiling contact parts joined to the cross beam part. The fall is strongly prevented. Further, the first and second ceiling abutting portions are brought into contact with the corner portion having a relatively high strength by concentrating strength members such as columns and braces supporting the side walls and cross beams supporting the ceiling. The installation strength is higher than that of a conventional handrail device that fixes the column using the vicinity and the vicinity of the center of the ceiling, and the side wall and the ceiling are not deformed.

  In particular, the first ceiling contact portion extends laterally from the cross beam portion at one end of the cross beam portion, and the second ceiling contact portion extends laterally from the cross beam portion at the other end of the cross beam portion. In the case where the first ceiling contact portion and the second ceiling contact portion are extended to the vertical direction, the longer the extension length, the more the horizontal beam portion and the column portion are prevented from rotating in the vertical direction. The effect is further enhanced.

  As long as the first and second upper side wall contact portions and the first and second ceiling contact portions extend laterally from the joint portion with the cross beam portion, members such as a plate shape, a prismatic shape, or a cylindrical shape are used. The overall shape of the first ceiling corner fixing portion and / or the second ceiling corner fixing portion is preferably a rod shape. For this reason, it is preferable that the cross-sectional shape of the first ceiling corner fixing portion and / or the cross-sectional shape of the second ceiling corner fixing portion is L-shaped, B-shaped or substantially circular.

  When the ceiling corner fixing part has the shape and the cross-sectional shape as described above, the corner part between the side wall and the ceiling can be pressed reliably and strongly despite the simple and relatively light structure. It becomes possible, and the appearance at the corner is also refreshed. In particular, when the cross-sectional shape of the ceiling corner fixing portion is L-shaped, B-shaped or substantially circular, the contact surface of the first upper side wall contact portion and the first ceiling contact portion are in contact with each other. The surface and / or the contact surface of the second upper side wall contact portion and the contact surface of the second ceiling contact portion include contact surfaces that are substantially orthogonal to each other.

  For this reason, since the ceiling corner fixing portion can be simultaneously brought into contact with the side wall and the ceiling in one member, it is extremely advantageous in terms of strength and weight. In addition, when the cross-sectional shape of the ceiling corner fixing part has a substantially circular shape, or even if the cross-sectional shape is L-shaped or B-shaped, if the surface has a spacer, the side wall and the ceiling Even if the peripheral edge is installed at the corner portion, it can be easily brought into contact with the side wall and the ceiling at the same time.

  Further, when the first ceiling corner fixing portion and / or the second ceiling corner fixing portion is rod-shaped, or the cross-sectional shape of the ceiling corner fixing portion is L-shaped, B-shaped or substantially circular, etc. In some cases, the contact surface of the first upper side wall contact portion and the contact surface of the first ceiling contact portion are formed continuously with each other, and / or the second When the contact surface of the upper side wall contact portion and the contact surface of the second ceiling contact portion are formed continuously with each other, the strength of the member is further improved. It becomes possible to press the corner portion of the head more reliably and more strongly.

  Note that the first and second upper side wall abutting portions and the first and second ceiling abutting portions described above do not have to be in contact with the side walls and the ceiling uniformly, and are joined to the cross beam portions. As long as it can contact the side wall and the ceiling at a position away from the side, the contact form may be approximate to point contact. If the side wall and the portion in contact with the ceiling are laterally separated from the joint portion with the cross beam portion, the first and second upper side wall contact portions and the first and second ceiling contact portions are in contact with the cross beam portion. This is because rotation in the direction extending from the joint can be effectively prevented.

  Further, like the first and second ceiling corner fixing portions, the cross beam portions are preferably rod-shaped. If the cross beam is also in the shape of a rod, not only can it obtain a strong strength despite its simple and relatively light structure, it can easily avoid lighting fixtures and sensors installed on the ceiling. Since it can arrange | position, the freedom degree of attachment of a handrail apparatus increases, and attachment itself becomes easy.

  Moreover, in the handrail device of the present invention, a plurality of handrail portions attached to the strut portions and the strut portions described above may be provided. In this case, the second support column may be attached to a cross beam or base other than the cross beam or base to which the first support is attached, or the first support is attached. It may be attached to the cross beam or base. As in the latter case, when the horizontal beam part and the base part for connecting the column parts are made common, the rigidity and strength of the entire handrail device as a structure are further improved by the integration of the entire handrail device. Further, by providing a plurality of handrails attached to the support post and the support post, the required arm length of the handrail is less than ½ compared to the case of providing one support post. Therefore, the bending moment applied to the support column can be greatly reduced, and the rotation and twisting of the support column and the handrail can be effectively prevented.

  According to the handrail device of the present invention, an elderly person or a person who needs care takes a standing posture or a sitting posture in order to make it easy to take a standing posture or a sitting posture in a space such as a toilet, an entrance, or a bathtub. Even if a moment is applied to the column through the column or handrail, the column is not misaligned or the column is not fixed, especially the column or handrail rotates, or the column rotates. Thus, the support can be firmly erected without being disengaged and without deforming the ceiling.

  In addition, since the handrail device of the present invention has a simple housing structure and can select a space-saving member such as a bar shape, the installation location of the handrail device is limited to a closed space such as a toilet or a bathtub. If it has a floor surface and a ceiling, such as an entrance and a corridor, and two or more side walls extending downward from the ceiling, it can be installed even in an open space.

  Hereinafter, a handrail device according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiments shown below, and various modifications can be made without departing from the technical idea of the present invention.

[First Embodiment]
FIG. 1 shows a perspective view of a handrail device 1 according to the first embodiment of the present invention installed in a space such as a toilet.

  The handrail device 1 according to the present embodiment includes a lateral beam portion 2 having an expansion / contraction means 20, and extends laterally from the lateral beam portion 2 at one end portion of the lateral beam portion 2. The first ceiling corner fixing portion 3L having the first upper side wall contact portion 30L that is in contact with the side wall and the other end portion of the horizontal beam portion 2 that extends laterally from the side beam portion 2 are opposed to each other. A second ceiling corner fixing portion 3R having a second upper side wall abutting portion 30R that abuts against the other side wall of the side walls, and extends downward from the transverse beam portion 2, and is floored via the base portion 5. A support column 4 is provided.

  In the present embodiment, the support column 4 has expansion / contraction means 40, further extends laterally from the support column 4, can be rotated and fixed in the horizontal direction with respect to the support column 4, and is adjusted in height. It includes a handrail portion 41 that is attached in a possible manner.

  In the present embodiment, the base 5 is a base plate 50 installed on the floor, and a first lower side wall abutting portion that extends from the floor and abuts against one of the two opposing side walls. A first floor surface corner fixing portion 52L having 51L, and a second floor surface corner fixing portion 52R having a second lower side wall abutting portion 51R that abuts against the other of the opposing side walls. The first floor surface corner fixing portion 52L and the second floor surface corner fixing portion 52R adjust the distance between the first floor surface corner fixing portion 52L and the second floor surface corner fixing portion 52R. It is attached to the base plate 50 as possible.

  Next, each component of the handrail device 1 of the present embodiment will be described in detail below. The support column 4 erected on the floor surface has a bar shape extending from the floor surface to the vicinity of the ceiling, so that the length (height) of the support column 4 can be made variable or between the floor surface and the ceiling. The strut portion 4 is provided with expansion / contraction means 40 so that it can be stretched between them. Further, even when the support column 4 is tilted, an urging means (not shown) such as a spring is auxiliary to the support column 4 or the expansion / contraction means 40 so that the tensioned state by the support column 4 can be maintained. It may be attached.

For this reason, the support column 4 erected so as to be fixed to the base plate 50 and the handrail portion 41 attached to the support column 4 are strongly prevented from rotating and twisting via the base 5.

  Next, the horizontal beam part 2 attached to the upper end of the column part 4, the first ceiling corner fixing part 3L and the second ceiling corner fixing part 3R attached to the end part of the horizontal beam part 2 will be described in detail.

  In the handrail device 1 of the present embodiment, the lateral beam portion 2 is attached to the upper end of the support column 4 so as not to rotate around the support column 4. Further, in order to make the length of the horizontal beam portion 2 variable or between the opposing side walls, the horizontal beam can be stretched via the first ceiling corner fixing portion 3L and the second ceiling corner fixing portion 3R. The part 2 is provided with expansion / contraction means 20. Further, even when the first ceiling corner fixing portion 3L or the second ceiling corner fixing portion 3R moves from the abutting side wall, the horizontal beam portion 2 can be maintained so that the stretched state by the horizontal beam portion 2 can be maintained. Alternatively, a biasing means (not shown) such as a spring may be supplementarily incorporated in the expansion / contraction means 20. Although not shown in the drawings, the support column 4 may be joined so that the mounting position on the cross beam 2 can be changed as long as it is fixed to the cross beam 2 so as not to rotate in the horizontal direction with respect to the cross beam 2.

Although not shown, if the first and second ceiling corner fixing portions 3L and 3R are fixed to the cross beam portion 2 so that the connection angle cannot be changed with respect to the cross beam portion 2, they are attached to the cross beam portion 2. You may join so that a position can be changed.

  In the handrail device 1 of the present embodiment, the first upper side wall contact portion 30L and the second upper side wall contact portion 30R extend in the lateral direction along the side wall. 30L is abutted against one of the two opposing side walls, the second upper side wall abutting part 30R is abutted against the other of the opposing side walls, and the first ceiling corner fixing part If 3L and the 2nd ceiling corner fixing | fixed part 3R are fixed to the cross beam part 2, the cross beam part 2 will not be able to physically rotate with respect to the opposing side wall.

  That is, the first and second upper side wall abutting portions 30L and 30R extending laterally along the side wall from the lateral beam portion 2 are fixed to the lateral beam portion 2 in an angle invariable in the horizontal direction. The rotation in the horizontal direction is restricted, and in particular, the horizontal beam portion 2 is strongly prevented from rotating in the horizontal direction.

  FIG. 6 schematically shows an example of the mounting arrangement of the ceiling corner fixing portions 3L and 3R in plan view. As understood with reference to FIGS. 6A and 6B, the first and second ceiling corner fixing portions 3L and 3R abut against each of the two opposing side walls.

In particular, when the first and second ceiling corner fixing portions 3L ′ and 3R ′ are arranged using the corner portions of adjacent side walls, a pressing force is given by the expansion / contraction means 20 ′ of the cross beam portion 2. Since the first and second upper side wall abutting portions 30L ′ and 30R ′ abut on and fit into the corner portions of the side walls so as not to rotate in the horizontal direction, the beam portion 2 is further prevented from rotating in the horizontal direction. can do.

  As a result of the above, in the handrail device 1 of the present embodiment, the column portion 4 that is non-rotatably joined to the cross beam portion 2 and the handrail portion 41 attached to the column portion 4 are the cross beam portion 2 and the cross beam portion 2. Rotation and twisting are strongly prevented through the first and second upper side wall contact portions 30L, 30L′30R, 30R ′ joined to each other. The first and second upper side wall abutting portions 30L, 30L′30R, 30R ′ are corner portions having relatively high strength due to concentration of strength members such as columns supporting the side walls, bracing, and horizontal beams supporting the ceiling. Therefore, the installation strength is higher than the conventional handrail device that fixes the column using the vicinity of the center of the side wall or near the center of the ceiling, and the side wall and the ceiling are not deformed.

Next, the first and second floor surface corner fixing portions 52L and 52R are pulled out from the base plate 50 placed on the floor surface until they abut against the respective side walls, and are fixed to the base plate 50 with screws 500.

  Then, the length (height) of the column part 4 is set so that the first and second ceiling corner fixing parts 3L and 3R attached to the upper end of the column part 4 via the cross beam part 2 come into contact with the ceiling. It is adjusted and fixed by the telescopic means 40. After fixing the length (height) of the support column 4 so that the support column 4 is stretched between the floor and the ceiling, the first and second ceiling corner fixing units 3L and 3R are brought into contact with the respective side walls. The length (height) of the cross beam portion 2 is adjusted and fixed by the expansion / contraction means 20 so as to be in contact with each other and stretch between the opposing side walls.

The ceiling corner fixing part 3aR of the handrail device 1 according to the first embodiment, except that the ceiling corner fixing part 3aR also has a second ceiling contact part 31R that comes into contact with the ceiling extending from the other side wall. It has the same configuration. For this reason, the handrail apparatus 1a of this embodiment can have the same effect as the handrail apparatus 1 according to the first embodiment. Further, in the handrail device 1a of the present embodiment, descriptions of configurations, effects, and installation methods that are the same as those of the handrail device 1 according to the first embodiment are omitted.

  In the handrail device 1a of the present embodiment, the first ceiling corner fixing portion 3aL has a first ceiling abutting portion 31L that abuts against a ceiling extending from one side wall, and the second ceiling abutting portion 31L is provided. The ceiling corner fixing portion 3aR also has a second ceiling abutting portion 31R that abuts against the ceiling extending from the other side wall. For this reason, in the handrail device 1a of the present embodiment, the support column portion 4 joined to the cross beam portion 2 includes the cross beam portion 2 and the first and second ceiling contact portions 31L and 31R joined to the cross beam portion 2.
