Description

  The present invention relates to an auxiliary handrail, and more particularly, to an auxiliary handrail suitable for supporting one's own body, especially when elderly people and physically disabled people stand up and sit down.

  The elderly and physically disabled people (hereinafter referred to as elderly people) are much more likely to fall than healthy people, and even homes that are accustomed to living will not be cautious. Once the elderly fall, most of them are injured, such as bruises and scuffs, leading to serious injuries such as injuries and fractures that would require surgery in the worst case. This has also been reported in the Cabinet Office's "Consciousness Survey on Housing and Living Environment for the Elderly (2010)." In addition, the current situation is that falling accidents do not stop at places with steps such as stairs and entrances and occur frequently even in the same plane, which is nothing for healthy people.

  Various devices have been proposed so far to prevent such a fall accident.

  For example, Patent Document 1 discloses a tension-type handrail that is held by hand when an elderly person or the like stands up to support the body. The handrail comprises a lower pipe whose lower end abuts on the floor, an upper pipe inserted in the lower pipe and an upper end whose upper end abuts on the ceiling, an upper holder and a lower holder, and a rotating lever. It can be tensioned and fixed between the ceiling and the floor just by turning. In addition, in this handrail, it is possible to provide a front U-shaped grip on the lower pipe, and it is possible to support the body by holding this grip as well as the upper and lower pipes. It is.

  Further, Patent Document 2 is installed in toilets and bathrooms such as medical and welfare facilities and general houses, and the handrail is rotated between a vertical state and a horizontal state to be used as an aid for elderly people etc. A movable handrail is disclosed. In this handrail, the tip end of the handrail member is bent in a U-shape, and it is intended not to be injured even if it strikes the tip.

JP 2008-75383 A JP 2011-106250 A

  By the way, since the elderly people generally have a weaker grip than a healthy person, they grasp their bodies by grasping a handrail attached vertically to a wall surface or a pillar-like handrail as disclosed in Patent Document 1 above. I can not support it enough. Therefore, for elderly people with weak grip, a handrail that protrudes from a column as seen in Patent Document 1 or a handrail that protrudes from a wall surface as seen in Patent Document 2 does not have to be held firmly, in a sense of putting a palm on. Because it can be used, it is more convenient to support your body than vertical columns.

  However, looking at the shape of such a handrail, as represented by Patent Document 1 and Patent Document 2, the tip of the handrail is rounded from the viewpoint of securing safety at the time of a collision. That is, in the grip portion as described in Patent Document 1, the entire shape is formed in a front U-shape, but the connection portion between the lateral weir and the longitudinal weir that make up this is curvilinear . Moreover, in the handrail as described in Patent Document 2, the tip end portion is U-shaped. Therefore, for example, when an elderly person holds a weight close to the tip of the handrail of the above-mentioned shape as a stand-up, for example, the weight does not firmly hold the handrail, and the weight moves toward the tip of the handrail in the stand-up operation. There is concern that the hand may slip off the tip of the handrail. If the hand slides down from the tip of the handrail during the stand-up operation, the shock of falling is larger because the handrail supports the body, which may result in a serious injury accident. In addition, for example, when holding the above-mentioned curved portion in an operation to lower the waist, the stepping action of the hand does not work, and for this reason, there is also concern that the operation can not be performed properly or a fall accident is caused. Furthermore, in any of the above-described handrails, the curved portion is a shape that can grip any portion from the distal end to the proximal end, so that it is a curved portion that is undesirable in the actual usage method. There is also a problem that it is easy to cause misuse such as holding a certain tip, and hence it is difficult to use it or such misuse causes an accident.

  The present invention was made to ameliorate such problems, and provide an auxiliary handrail that can be used safely even by elderly people with weak grip, etc., by preventing the hand from sliding off the tip. It is a thing.

  In order to achieve the above-mentioned object, the auxiliary handrail of the present invention has a base end side as an attachment portion attached to a wall surface or a post member, and a distal end side as a free end and a state where it protrudes from the wall surface or the post member An auxiliary handrail provided at the end of the handrail body, and a sliding prevention portion provided at the tip of the handrail body for preventing the user's hand placed on the handrail body from sliding off the tip of the handrail body , Adopted, and adopt the configuration.

  According to the present invention, the elderly person etc. put his hand on the tip of the handrail main body of the auxiliary handrail to support his / her body when standing up or down, for example, when trying to stand up, the handrail main body Even if the gripping force is weak and the hand slips toward the tip of the handrail body, the hand stops at the point where it collides with the anti-slip portion provided at the tip, preventing the hand from sliding off the tip of the handrail body Ru. Therefore, it is possible to prevent a fall accident caused by the hand sliding from the handrail, and to protect elderly people and the like from a serious injury accident such as a fracture. In addition, even if you suddenly grip the sliding prevention part instead of the handrail body, the hand received from it is different from that received from the handrail body, so the user is informed that he is trying to grasp the wrong part, and the handrail correctly. It can be urged to hold the body, and misuse can be prevented.

  In the above-mentioned auxiliary handrail, it is preferable that the slip prevention portion has a spherical surface.

  In this case, even if an elderly person or the like collides with the tip of the handrail, there is no risk of injury. In addition, even if you grasp the slide prevention part suddenly instead of the handrail main body, the surface is spherical, and the shape is clearly different from the handrail main body, and try to grasp the wrong part for the user at the moment of touching the hand It can be informed that it is in place and prompt you to hold the handrail properly.

  In the above-mentioned auxiliary handrail, it is preferable to have a support rod which is connected at one end to the lower surface side of the handrail main body and whose other end is an attachment portion of the same shape as the attachment portion of the handrail main body.

  In this case, the auxiliary handrail can be supported by the wall surface or the support member at the upper and lower two points, so that the mounting strength of the entire auxiliary handrail can be secured.

  Further, in the auxiliary handrail having the support rod, one end of the support rod is preferably connected to the handrail main body at the tip of the handrail main body.

  In this case, since one end of the support rod is connected to the tip of the handrail body, there is no possibility that the clothes are hooked on the tip of the handrail body, for example, to prevent the breakage of the clothes and the fall accident resulting from that. Can.

  Moreover, in the said auxiliary handrail, one part or the whole of a sliding-off prevention part may be made into the luminous part.

  In this case, since the user can be notified of the position of the auxiliary handrail even at night, the position of the auxiliary handrail can be recognized and grasped without lighting the room. In particular, it is effective at the bedside.

  According to the present invention configured as described above, it is possible to provide an auxiliary handrail that can be used safely even with an elderly person with weak grip by preventing sliding of the hand from the tip. .

Hereinafter, the respective units will be described in detail.

<Handrail main body>
The handrail main body 4 is a rod-like member whose cross-sectional shape is circular. Specifically, for example, a resin-coated steel pipe for lightweight structure in which the outer peripheral surface of a thin steel pipe is covered with a synthetic resin layer, a resin-coated aluminum pipe in which the outer peripheral surface of an aluminum pipe is coated with a synthetic resin layer, or a synthetic resin According to the present invention, it is possible to adopt a lightweight structural pipe material, or a solid lightweight structural bar material made of synthetic resin or wood. The thickness is arbitrary as long as it is easy to grip, and for example, one having an outer diameter of 30 mm to 40 mm is suitable. The cross-sectional shape is not limited to the above-mentioned circular shape as long as it is easy to grip, and is arbitrary. For example, the upper surface and both side surfaces may be arc surfaces, and the lower surface may be an uneven surface formed by a curve along the fingers of the user M. Alternatively, the cross section may be a cross section in which the apex of the triangular rice ball is directed downward.

  The handrail main body 4 thus formed is formed in a linear shape, and the base end side thereof is used as the attachment portion 2. In the present embodiment, as shown in FIGS. 3 to 7, the attachment portion 2 is separate from the handrail main body 4, and can be attached to the support member A.

  Specifically, as shown in FIG. 1 to FIG. 3, a socket 21 to which the base end of the handrail main body 4 is inserted and fixed, and a fixing screw for fixing the socket 21 and the base end of the handrail main 4 22 and 22, a grip portion 23 for gripping and supporting the column member A, a fastening screw 24 for fastening the grip portion 23 to the column, and a slip for increasing frictional resistance between the grip portion 23 and the column member A It is comprised from the stop member 25. As shown in FIG.

  The socket portion 21 is formed in a cylindrical shape having an inner diameter substantially the same as the outer diameter of the handrail main body 4, and screw holes 21a and 21a are provided at two places in the middle in the axial direction. . And the socket part 21 is fixed to the base end part of the handrail main body 4 by the fixing screws 22 and 22 through these screw holes 21a and 21a.

  The grip part 23 is comprised from the half members 23a and 23b and the hinge part 23c which connects these half members 23a and 23b so that opening and closing is possible.

  One side 23a of the half members 23a, 23b is provided integrally with the socket portion 21 on the opposite side of the hinge portion 23c. Moreover, the lock part 23d is provided in the other side of the hinge part 23c in the other 23b of the half members 23a and 23b. The lock portion 23d can be fitted in the fitting recess 21b provided at the proximal end of the socket portion 21, and when the lock portion 23d is fitted in the fitting recess 21b, the socket portion 21 and the outer surface It is formed in the shape which continues in a row. Further, a convex portion 21d is formed on the bottom surface 21c of the fitting concave portion 21b, and a screw hole 21f screwed with the fastening screw 24 is provided in the convex portion 21d. In addition, the surface 23e of the other half member 23b facing the fitting recess 21b is provided with a notch 23f to be fitted with the protrusion 21d, and a fastening screw 24 is provided so as to penetrate the notch 23f. An insertion hole 23g for the purpose is provided.

  The non-slip member 25 is preferably made of a material such as a polyamide resin, an elastomer, or urethane rubber that generates a large frictional force with respect to the surface of the support member A, and is attached to the inner surfaces of the half members 23a and 23b. It is worn.

<Slip prevention part>
The sliding prevention unit 5 includes a first socket 51 into which the tip of the handrail main body 4 is inserted, a substantially spherical enlarged portion 53 whose outer diameter is larger than the outer diameter of the handrail main 4, and a tip of the support rod 6. Is integrally formed with the second socket portion 52 to which the. The slip prevention portion 5 is preferably made of a synthetic resin because it gives a cold feeling to the hand H of the user M when held by metal. For example, polypropylene resin and acrylonitrile butadiene styrene resin (ABS resin) are preferable. In addition, synthetic resins other than this may be used.

  The first socket portion 51 is formed in a cylindrical shape having an inner diameter that is substantially the same as the outer diameter of the handrail main body 4 and, as shown in FIG. Screw holes 51a, 51a are provided over the entire area. The first socket portion 51 is fixed to the tip of the handrail main body 4 by the fixing screws 54 via the screw holes 51a. The screw holes 51a and 51a are preferably provided on the lower surface side of the first socket portion 51 which is hard to contact with the user's hand.

  As described above, the enlarged portion 53 is formed in a substantially spherical shape whose outer diameter is larger than the outer diameter of the handrail main body 4. When the hand H of the user M slides on the handrail main body 4 toward the tip end side, the hand H is sufficiently caught and the size (outside diameter) of the enlarged portion 53 The size is not particularly limited as long as the hand H can be prevented from slipping from the tip. Moreover, as long as it can prevent the sliding of the user's hand, it may have a shape other than a substantially spherical shape. For example, although not shown, the surface facing the base end side of the handrail main body 4 is concave such that it rises from the upper surface of the handrail main body 4 while the outer surface bulges outward. And the shape in which the tops of these two surfaces are connected by a gentle curved surface is given as an example.

  The second socket portion 52 is provided in a direction in which the axial centers of the second socket portion 51 and the first socket portion 51 are substantially orthogonal to each other, and is formed in a cylindrical shape having an inner diameter substantially the same as the outer diameter of the support rod 6. Further, as shown in FIG. 2B, screw holes 52a and 52a are provided at two places in the middle of the axial direction. Then, the second socket portion 52 is fixed to the tip end portion of the support rod 6 by the fixing screws 55, 55 through the screw holes 52a, 52a. The screw holes 52a and 52a are preferably provided on the inner surface side (surface side facing the attachment portion 2) of the second socket 52 which is hard to contact with the user's hand.

<Supporter>
The support rod 6 has the same outer diameter as the handrail main body 4 and is formed of the same material, and draws a curve from the horizontal portion 61 parallel to the handrail main body 4 and the tip of the horizontal portion 61 It consists of a curved portion 62 which is raised. In addition, since this support rod 6 is not something which a user can hold positively, it is not necessary to employ the modification of the form of the handrail main body 4 as mentioned above in particular, and what is necessary is just to make it a cross section circular simply. The distance D between the horizontal portion 61 and the handrail main body 4 is 120 mm in a state where one end of the support rod 6 thus made, that is, the tip end of the curved portion 62 is inserted into the second socket portion 52 of the slip prevention portion 5 It is desirable to take a form that is less than or greater than 235 mm. This conforms to JIS T 9281 and JIS T 9254 established for the purpose of preventing an accident in which the user M's neck or body is pinched, and the user is considered to have the above-mentioned interval D in the range of 120 mm to 235 mm. There is a risk that M may cause an accident in which the neck or the like can not be slipped between the supporting rod 6 and the handrail main body 4. A desirable distance D is 265 mm or more, but if the distance D is too wide, the user M may erroneously hold the support rod 6 instead of the handrail main body 4. In particular, when the user M has an executive dysfunction that causes him or her to panic if taken by an extrinsic behavior other than the regular behavior pattern, the grip error of the handrail main body 4 and the support rod 6 is a serious accident There is a risk of inviting Therefore, it is necessary to set the optimum interval D from such a viewpoint.

  The other end of the support rod 6 thus configured, that is, the base end side of the horizontal portion 61 is the attachment portion 2. Since this attachment part 2 is the same structure as the attachment part 2 in the handrail main body 4 mentioned above, description is abbreviate | omitted.

  As length L of the auxiliary handrail 1 demonstrated above, 100 mm-300 mm are preferable.

  Moreover, in the said auxiliary handrail 1, one part or the whole of the sliding-off prevention part 5 may be made into the luminous part. In this case, since the user can be notified of the position of the auxiliary handrail 1 even at night, the position of the auxiliary handrail 1 can be recognized and grasped without lighting the room. In particular, it is effective at the bedside.

<Example of using auxiliary handrail>
The auxiliary handrail 1 described above is, as shown in FIG. 3 and FIG. 4, a support member A of a support post P installed in a state of tension between a ceiling and a floor in a room or as shown in FIG. , The support member A of the standup aid S installed on the bedside, or as shown in FIG. 6, the support pillar A of the strut P having the standup aid S installed between the sofas, etc. , Attached via attachment part 2. For example, when the height position is attached to a strut P installed near the rising edge K of the entrance E as shown in FIG. It can be in a position where it can be held or a position where it can be firmly held. In addition, when attached to the bedside rising aid T as shown in FIG. 5, the user can lower the foot from the bed B and sit on the bed B so that the handrail main body 4 can be securely gripped. Ru. Moreover, also when attaching to the standup assistance tool S installed between sofas F as shown in FIG. 6, the position where the handrail main body 4 can be reliably grasped in the state of being seated on the sofas F and the above-mentioned example Be done.

  FIG. 7 shows a state in which the user M is about to stand up in an example in which the auxiliary handrail 1 is attached to the support member A of the upright support post S with the upright support S installed between the sofas F. The user M first grips the handrail main body 4 of the auxiliary handrail 1 while sitting down, and then, as shown in FIG. 7, extends the elbow while supporting the body with the hand H held by the handrail main body 4 stand up. At that time, since the auxiliary handrail 1 is in front of the position of the upper body in the sitting state, the rising operation can be performed smoothly. In addition, since the upper body is bent forward during the rising, the hand H may slide to the tip side of the handrail body 4 if the handrail body 4 is not firmly held. However, since the anti-slip portion 5 is provided at the tip of the handrail main body 4, even if the hand H slips, the anti-slip portion 5 receives the slip. As a result, there is no accident that the hand H slides down from the tip of the auxiliary handrail 1 and falls during the rising operation. In addition, in the operation at the time of sitting on the sofa F, as in the case of the rising operation, an accident that the hand H slips off from the tip of the auxiliary handrail 1 and falls does not occur.
