Description

  The present invention relates to a handrail attached to a wall surface such as a staircase, a corridor, a toilet, a bathroom, and an entrance.

  In recent years, various handrails have been proposed that make it difficult to remove the attachment arm of the grip bar, simplify the attachment work of the attachment arm, and can be easily installed according to the attachment location.

  As a typical example of such a handrail, the one proposed in Patent Document 1 can be cited.

A handrail disclosed in Patent Document 1 includes a base member attached to a wall surface, a cover member attached to and covering the base member, and a base end portion passing through the cover member in the fitting portion of the base member. And an arm member to be fitted.
An annular groove is provided on the outer peripheral surface of the base end portion of the arm member, and the base end portion is rotatably provided in the fitting portion of the base member and penetrates the outer periphery of the fitting portion of the base member. The arm member is fixed by a fixing member that bites into the annular groove, and a receiving seat for attaching a grip rod is provided at the tip of the arm member.

  According to the said structure, while fixing the said arm member with the fixing member which bites into the said annular groove, the said fixing member latches to the step part of the said annular groove, and exhibits the retaining function. In particular, for example, when a handrail is installed at an inclined place such as a staircase, the arm member is inclined in the rotation direction so that the receiving seat is placed along the installation line of the grip bar.

JP 2002-180632 A

  However, in the handrail according to Patent Document 1, since the three members of the base member, the arm member, and the grip bar are separate bodies, as a result, the construction time is increased and the construction cost is also increased. It is a fact.

  The present invention has been made in view of the above technical problem, and an object of the present invention is to provide a handrail capable of shortening the construction time and reducing the construction cost.

  The present invention is a longitudinal base member attached to a wall surface, arranged at a predetermined interval from the wall surface to which the base member is attached, and is gripped by the user's palm when the user tries to slide by hand. And a longitudinal arm that defines a space in which four fingers except the user's thumb can be inserted together with the grip member, the base end portion is fixed to the base member, and the distal end portion supports the grip member In the handrail provided with the member, the grip member and the arm member are integrally formed.

  Moreover, the length dimension of both the said grip member and an arm member is substantially the same dimension mutually, and also is substantially the same dimension as the length dimension of the said base member.

  Further, a recess is formed through the longitudinal direction in the region where the four fingertips of the grip member are hooked, and this recess is a groove part of which is inward of the grip member. It has a shape.

  Furthermore, the joint point between the tip portion of the grip member and the arm members is spaced from the center of the grip member toward the side opposite to the wall surface.

  In addition, at least both of the grip member and the arm member are made of synthetic resin as a raw material, so that the inside of the both is made hollow. A required number of aggregates are provided along a direction that intersects a direction in which a weight of the user is applied when the user tries to move in a desired direction.

  Further, both the grip member and the arm member are transparent, and the aggregate on the grip member side is inserted into a space defined by the aggregate and the region including the upper surface of the grip member. In order to insert the body, the grip member has a substantially horizontal surface with respect to the upper surface and the lower surface.

  (1) Since the grip member and the arm member are integrally formed, the construction time of the handrail is shortened and the construction cost is reduced.

  (2) The handrail is continuously installed along the wall surface. At this time, since the length dimensions of both the grip member and the arm member are substantially the same as each other, and the length dimension of the base member is also substantially the same, one grip member, the arm member, and the other grip member And the arm members are connected to each other. Therefore, when the user slides his / her hand, the hand is not caught in the gap between the adjacent handrails. As a result, a fall accident can be prevented in advance.

  (3) In the region where the four fingertips of the grip member are hooked, a recess is formed along the longitudinal direction, and this recess has a shape of a groove in which a part of the recess enters the inside of the grip member ( For example, the user can hold the grip member firmly while hooking a finger in the recess. In this respect as well, a fall accident can be prevented.

  (4) Since the joint point between the front end portion of the grip member and the arm members is separated from the center of the grip member toward the side opposite to the wall surface, the finger is easily hooked into the recess of the grip member.

  (5) Since at least the grip member and the arm member are made of synthetic resin as a raw material, the inside of the both is made hollow, so that the weight of the handrail as a whole is reduced. As a result, construction work on site is relatively easy. In addition, in the hollows of both the grip member and the arm member, respectively, along a direction intersecting with a direction in which the weight of the user is applied when the user tries to move in a desired direction by sliding his hand. Since the required number of aggregates is provided, there is no problem with strength.

  (6) Since both the grip member and the arm member are transparent, it is possible to eliminate the feeling of pressure caused by the entire handrail. In addition, the aggregate on the grip member side has an upper surface and a lower surface of the grip member so that an insert of an arbitrary color can be inserted into a space defined by the aggregate and a region including the upper surface of the grip member. Therefore, when the insert is inserted into the hollow and placed on the horizontal surface of the aggregate of the grip member, the design of the entire handrail is improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Embodiment 1>
As shown in FIGS. 1 and 2, the handrail according to the first embodiment of the present invention includes a base member 1 attached to a wall surface, a grip member 2 gripped by a user's palm, and an arm that supports the grip member 2. The grip member 2 and the arm member 3 are integrally formed, and the arm member 3 is fixed to the base member 1.

  The base member 1 is formed in an L-shaped cross section, and includes a flat surface portion 10 and a support portion 11 that protrudes perpendicularly to the lower portion of the flat surface portion 10. The base member 1 is formed to a predetermined length in the longitudinal direction by aluminum extrusion. A cut portion 12 is formed in the plane portion 10 along the longitudinal direction on the wall surface side, and a plurality of screw holes for the fixing screw 13 are formed in accordance with the cut portion 12. A groove 14 for fitting the arm member 3 is formed in the support portion 11 in the longitudinal direction. Moreover, the screw hole 15 is formed so that the support part 11 may be penetrated in the up-down direction.

  The arm member 3 and the grip member 2 are integrally formed into a J-shaped cross section by extrusion molding of aluminum, and are formed in a predetermined length in the longitudinal direction. The length is substantially the same as the length of the base member 1. Each member is formed by extrusion, but is not limited thereto, and may be formed by cutting or pressing.

The base end portion 20 of the arm member 3 is formed in the horizontal direction, the tip end portion 21 is formed in the vertical direction, and the base end portion 20 and the tip end portion 21 are connected by a curved intermediate portion 22. And the base end part 20 is made thicker than the front-end | tip part 21, and the wall surface side of the base end part 20 is made into the fitting part 23 formed a little thinly. The fitting portion 23 fitted into the groove 14 of the base member 1 has a thickness slightly smaller than the groove width so that the fitting portion 23 does not rattle when fitted. Moreover, the screw hole 24 is formed so that the fitting part 23 may be penetrated in the up-down direction.

  The grip member 2 is formed in a hollow cylindrical shape, the upper surface 30 is a flat surface, the radius of curvature of the wall-side curved surface 31 is larger than the radius of curvature of the indoor-side curved surface 32, and the wall-side lower surface 33 and the indoor side The lower surface 34 is a flat surface, and the lower surface 33 on the wall surface side is located below the lower surface 34 on the indoor side. Thereby, the wall surface side of the grip member 2 becomes thicker than the indoor side so that it can be easily gripped by the palm of the user. Further, a screw insertion screw groove 35 for screwing a cover member (not shown) is formed in the lower part of the grip member 2 along the longitudinal direction.

  A junction point 36 between the grip member 2 and the distal end portion 21 of the arm member 1 is located closer to the indoor side than the center of the grip member 2. Thereby, since the grip member 2 is located away from the wall surface, a space surrounded by the base member 1, the arm member 3, and the grip member 2 is widened, and a fingertip can be easily inserted.

  When the handrail is attached to a wall surface such as a staircase, a corridor, a toilet, a bathroom, and a front door, the base member 1 is first positioned at a predetermined position on the wall surface and fixed to the wall surface with screws 13. As the screw 13 is screwed in, shavings emerge from the wall, but since it accumulates in the gap between the notch 12 of the base member 1 and the wall surface, the adhesion of the base member 1 to the wall surface is not impaired.

  Next, the arm member 3 is fitted into the base member 1 from the indoor side. When the fitting portion 23 of the arm member 3 is inserted all the way into the groove 14 of the support portion 11 of the base member 1, the screw 13 is screwed into the fitting portion 23 and the screw holes 15, 24 of the support portion 11 to prevent detachment. To do. The arm member 3 is fixed to the base member 1. At this time, the lower surface of the base end portion 20 of the arm member 3 and the lower surface of the support portion 11 of the base member 1 are flush with each other. Then, the cover member is attached to the grip member 2 with screws so as to close the end faces on both sides in the longitudinal direction of the grip member 2.

Here, the length of the handrail in the longitudinal direction is determined according to the wall surface to which the handrail is attached. Therefore, it is only necessary to prepare a set of the base member 1, the arm member 3, and the grip member 2, and the number of parts is reduced, so that the construction can be performed with good setup. It is also possible to connect two or more sets into a long handrail.

Thus, since the handrail is continuously installed in the longitudinal direction, the hand is not caught when the user moves while sliding the hand along the handrail. And since the space | interval of the grip member 2 and a wall surface is fully taken, it is easy to put four fingertips, and when gripping or releasing a handrail, it becomes easy to bend and spread a finger. Therefore, a handrail that is easy to grip can be realized. Moreover, since the grip member 2 and the arm member 3 are integrated, there is no joint between them, and the fingertip is not caught when the handrail is gripped.

A handrail according to a modification of the first embodiment is shown in FIG. A recess 25 is formed on the lower surface of the grip member 2 so that the fingertip can be easily hooked. The recess 25 is formed along the longitudinal direction as a groove in which the top 25a enters the inside of the grip member 2, and is recessed in a substantially V shape. Other configurations are the same as those of the handrail described above. The groove is not only V-shaped but also U-shaped, such as U-shaped.

  When the user grasps the handrail, the fingertip naturally bends along the recess 25 of the grip member 2. Thereby, force is applied to the fingertip, the handrail can be gripped firmly, and the function as a handrail can be fully exhibited.

<Embodiment 2>
A handrail according to Embodiment 2 of the present invention is shown in FIG. In the handrail according to the second embodiment, the fixing structure of the base member 1 and the arm member 3 is different from that of the first embodiment. That is, the upper rail 40 is formed upward along the longitudinal direction on the upper portion of the base member 1 formed in an L shape, the support portion 11 is provided on the lower portion, and the lower rail 41 is provided on the tip of the flat support portion 11. It is formed upward along the longitudinal direction.

The base end portion 20 of the arm member 3 is bent upward so that the base member 1 is completely covered. An upper concave portion 42 that is engaged with the upper rail 40 is formed in the upper portion of the base end portion 20 downward along the longitudinal direction. A lower recess 43 that is engaged with the lower rail 41 of the support portion 11 is formed on the lower surface of the base end portion 20 downward along the longitudinal direction.

Other configurations are the same as the handrails of the first embodiment and the modified example thereof.

  The arm member 3 is attached to the base member 1 fixed to the wall surface while sliding from the side. The upper concave portion 42 of the arm member 3 slides along the upper rail 40 of the base member 1, and the lower concave portion 43 slides along the lower rail 41, and the longitudinal end surfaces of the base member 1 and the arm member 3 coincide with each other. When this is done, the support portion 11 of the base member 1 and the base end portion 20 of the arm member 3 are fixed with the screw 44.

  Since the lower surface of the base end portion 20 of the arm member 3 is placed on the upper surface of the support portion 11 of the base member 1 and the arm member 3 is supported by the base member 1, the contact area between the both increases, and a load is applied to the grip member 2. Even if it is applied, it can be received by the base member 1 and the load bearing performance of the handrail is enhanced. And since the up-and-down recessed parts 42 and 43 engage with the up-and-down rails 40 and 41, even if an impact is applied to the grip member 2 from above, the arm member 3 does not tilt. Further, since the screw 13 for fixing the base member 1 to the wall surface is covered with the base end portion 20 of the arm member 3, it is excellent in aesthetics.

<Embodiment 3>
A handrail according to Embodiment 3 of the present invention is shown in FIGS. In the handrail according to the third embodiment, the base member 1, the arm member 3, and the grip member 2 are integrally formed. Each member is a molded product made of aluminum, and these shapes are basically the same as the handrail of the first embodiment, but the base end portion 20 of the arm member 3 is integrally connected to the upper portion of the base member 1. Is done. Therefore, a wall surface fixing screw hole 15 is formed in the lower portion of the base member 1. In addition, the cover member 4 is attached to both sides with a screw so as to close the end face in the longitudinal direction of the handrail.

  Thus, since the handrail becomes one component, handling at the time of construction becomes easy and construction time can be shortened. Further, since the screw 13 for fixing the base member 1 to the wall surface is located below the arm member 3, when viewed from above, the screw 13 is hidden and cannot be seen, and the appearance is improved.

  Here, as shown in FIG. 7, a covering member 45 for hiding the screw 13 of the base member 1 may be provided. An engaging groove 46 is formed on the indoor side of the base member 1 and the covering member 45 is fitted and fixed. As a result, the screw 13 is completely hidden, so that the appearance is further improved.

<Embodiment 4>
A handrail according to Embodiment 4 of the present invention is shown in FIGS. In the handrail according to the fourth embodiment, the base member 1, the arm member 3, and the grip member 2 are integrally formed. The shape of each member is the same as that of the handrail of the third embodiment, but is formed of a synthetic resin such as so-called plastic. Similarly, the cover member 4 is made of a synthetic resin.

Each member has a hollow structure, and a plurality of aggregates 50 are provided therein for reinforcement. The aggregate 50 of the base member 1 is formed in the horizontal direction. The aggregate 50 of the arm member 3 is formed in the vertical direction at the proximal end portion 20, formed in a substantially horizontal direction at the distal end portion 21, and formed in an oblique direction at the intermediate portion 22. The aggregate 50 of the grip member 2 is formed in the horizontal direction, and ribs 51 are formed between the aggregate 50 and the lower surface 33 on the wall surface side of the grip member 2, and screw grooves 52 are formed in the ribs 51. Each aggregate 50 is formed along the longitudinal direction and has the same dimension as the length of each member in the longitudinal direction.

  The grip member 2 and the arm member 3 are made of translucent synthetic resin (transparent plastic) so that the inside can be seen through. Inside the grip member 2, the upper and lower spaces are partitioned by the aggregate 50, and a color sheet 53 as an insert of an arbitrary color is formed in the space partitioned by the upper surface 30 of the grip member 2 and the aggregate 50. It is arranged. The color sheet 53 has a flat plate shape, is inserted from the longitudinal end surface of the grip member 2, and is placed on the horizontal surface of the aggregate 50.

  In the handrail described above, the base member 1 is fixed to the wall surface with screws 13. Then, after inserting the color sheet 53 into the grip member 2, the cover member 4 is mounted on the end surface of the handrail, and the attachment is completed. Since the handrail made of synthetic resin is lightweight, construction on site is easy.

  In addition, the use of translucent synthetic resin eliminates the feeling of handrail pressure in the room. In addition, the interior of the color sheet 53 improves the handrail design. In the present embodiment, a color sheet is used as an insert, but this is not limited as long as it is inserted into a gripping member such as a pipe or a block having an arbitrary color. Further, if a lamp such as an LED is installed inside the grip member 2, it can be used as a guide light instead of night illumination.

  The present invention is not limited to the above embodiments. For example, in each of the above-described embodiments, the grip member 2 and the arm member 3 are at least integrally formed. However, as shown in FIGS. 10 and 11, the arm member 3 and the base member 1 are integrally formed. Only the grip member 2 may be formed separately. That is, the arm member 3 and the base member 1 are integrally formed in a letter shape. The grip member 2 is the same as that in the above embodiment, but an engaging portion 55 that sandwiches the tip portion 21 of the arm member 3 is formed on the lower surface of the grip member 2. Then, the engaging portion 55 of the grip member 2 is fitted and engaged with the distal end portion 21 of the arm member 3 and is screwed. If it does in this way, since change of the grip member 2 is attained, the grip member 2 from which a shape differs according to a use can be used, and various handrails can be provided. In the first to third embodiments, the arm member and the grip member may be an integrally molded product made of synthetic resin. It goes without saying that various design changes and modifications can be made within the scope of the claims attached to the present specification.

  Since the construction time can be shortened and the construction cost is low, the present invention is useful, for example, as a handrail attached to the walls of stairs, hallways, toilets, bathrooms, entrances, and the like.
