Description

  [Technical Field] The present invention relates to a handrail bar for preventing getting over in a balcony of an apartment, an open corridor, or the like, in which measures are taken to prevent an accident in which a child climbs over a handrail and falls outside.

  In recent years, the number of apartment houses has risen, and the number of three-story detached houses has increased, resulting in an increasing number of accidents involving children and children. The main reason for this is that they fall accidentally from open corridors of condominiums and handrails on balconies.

  However, since the balcony and open corridor of a house usually require sufficient openness in terms of lighting, ventilation, and disaster prevention, both legally and comfortably, the height of the handrail is the minimum required by law. In general, handrails with a length slightly exceeding 1.1 m are provided.

  In this way, openness and prevention of children's fall accidents are physically contradictory matters, so there has been no definitive solution so far, and in order to prevent fall accidents, in addition to encouraging attention by enlightenment There was no way.

  Like the following patent document, although there are some ideas as a fall prevention measure, it is a handrail devised so that the lattice set part of a normal lattice-shaped handrail does not become a child's foothold, It only satisfies the general basic conditions for the safety performance of handrails and does not provide any further countermeasures.

  Alternatively, the upper space of the handrail is blocked by a fall prevention plate so that it does not fall, but this can only be installed in parts that do not require openness due to legal lighting, ventilation, and disaster prevention requirements. There is a problem that it can only be used in a general apartment.

  In addition, on the balcony of condominiums, various items such as air conditioner outdoor units have come to be placed with the residence, and even small infants can climb up the handrails as a foothold, resulting in a fall accident. Will lead to. This is a problem that cannot be addressed at present in terms of architectural planning.

  Furthermore, in open corridors such as condominiums, it is obliged to provide a handrail with a height of about 75 centimeters inside the handrail wall according to welfare laws. The handrail provided for this welfare consideration is an ironic footstep, and is one of the causes of a fall accident for elementary school children.

  The problem to be solved is to maintain the openness necessary for the law and functions in the balcony and open corridor of condominiums, etc., and to prevent accidents in which the child accidentally falls over the handrail It is a point to perform in the architectural aspect.

  The present invention relates to a handrail stick supporting member 2 supported by a building frame or the like in a balcony of an apartment or the like, a handrail stick provided on the upper stage of the handrail main body 17 in the open corridor, and a handrail stick provided for welfare on the surface of the open corridor handrail main body 17. The handrail bar 1 is fixed to the handrail bar receiving member 3 so that the handrail bar 1 can be rotated around the handrail bar core 6 so that the end of the handrail bar 1 is inserted.

  Further, the stopper 4 and the stopper receiving portion 5 are provided at the sliding contact portion between the handrail rod receiving member 3 and the end portion of the handrail rod 1 so that the rotation direction can be rotated only in the inner direction of the handrail.

  Further, in order to make the handrail rod 1 rotate more smoothly, a ball bearing 7 is provided around the sliding contact portion between the handrail rod 1 and the handrail rod receiving member 3. This is a handrail bar whose main feature is the above configuration.

  The handrail bar according to the present invention can rotate only in the direction of rotation 10 around the handrail bar core 6, and an infant 15 or the like 15 rides on some kind of footrest 20 on the balcony of an apartment or the like. When a force is applied to the hand or elbow to get out of the handrail with the hand as a cue, the handrail rod 1 rotates in the direction of rotation 10 by the action of the force. Accordingly, there is an effect of preventing the hand from slipping down in the direction of the arrow 11, losing the clue, not getting out of the half body, and falling down accidentally.

  In addition, the welfare handrail sticks provided in the open corridors of condominiums, etc. are installed at a height that can be used only by elementary school children 16 and so on. When trying to climb to the handrail body 17 as a footrest, as described above, if the foot is stepped on, the handrail rod 1 rotates in the direction of the rotation direction 10 and the foot slides in the direction of the arrow 14 so that it does not become a footrest. Even when it is a cue, it slides down in the direction of arrow 13 and does not become a cue. Further, the handrail rod 1 provided on the upper stage of the handrail body 17 also slides in the direction of the arrow 12 as in the case of the balcony, so that the handrail rod 1 does not become a cue and cannot climb to the handrail body 17. There is.

  In addition, the effect of rotation on the original use of welfare handrail sticks is because it is used to support the body weight by grasping the handrail sticks, and the direction of the force is directed to the outside or the vertical direction. It is not something that brings

  Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings. In a balcony of a condominium or the like, a handrail stick provided on the upper stage of the fall prevention handrail main body 17 provided in the open corridor, or a welfare handrail stick provided on the waist of the fall prevention handrail main body 17 provided in the open corridor, supported by a building frame or the like. A handrail rod cylindrical end having a shape that can be inserted into an appropriate length while having an appropriate structure with the handrail rod 1 with respect to the handrail rod receiving member 3 fixed to the handrail rod support member 2. The portion 8 is inserted so as to be rotatable around the handrail rod core 6.

  In addition, the rotating sliding contact portion of the handrail rod cylindrical end portion 8 inserted into the handrail rod receiving member 3 has a leaf spring shape inclined to one side so as to be able to contact the sliding contact portion of the handrail rod receiving member 3 during rotation. The stopper 4 is fixed. Further, a notched stopper receiving portion 5 that can be engaged with the stopper 4 is formed on the surface of the handrail rod receiving member 3 facing the stopper 4 so that only one rotation is possible around the handrail rod core 6. To do.

  In this case, the stopper receiving part 5 may be convex. In addition, the effect can be obtained if the number of the stoppers 4 is one or more, but it is desirable to have several parts from the viewpoint of strength and safety. The number of the stopper receiving parts 5 is larger regardless of the number of the stoppers 4. By providing, the play of reverse rotation decreases.

  Furthermore, by rotating the ball bearing 7 at an appropriate position between the handrail rod cylindrical end portion 8 and the rotation slide contact portion of the handrail rod receiving member 3, the rotational sliding becomes smoother and a more reliable effect can be obtained. I can expect.

  The handrail bar of the present invention is configured as described above, and when the handrail bar 1 is rotated, only one rotation is possible by the action of the stopper 4 and the stopper receiving part 5, so that the handrail bar is installed in a balcony, an open corridor, or the like. In this case, the effect of the present invention can be obtained by arranging and mounting the rotary shaft so as to rotate in the inner direction.

  Furthermore, when the handrail rod 1 of the present invention is rotated, a sound is generated that the leaf spring of the stopper 4 is repelled, so that there is a considerable effect as a warning sound that warns the child that the handrail is in danger. I can expect.

  Further, the same effect can be obtained when the handrail bar of the present invention is provided on the uppermost stage of a lattice-shaped handrail or a glass handrail. Alternatively, a fall-preventing handrail provided on the waist window is also a measure for preventing the fall.

  Installation places where the effects of the present invention can be expected are not only apartments, but all places where children are active, such as schools, parks, amusement parks, zoos, bridges, etc., and fall prevention handrails installed in such places Attaching the handrail bar of the present invention to the present invention is very useful as a measure for preventing children from falling.

  FIG. 6 is a sectional view in the direction of the rotation axis showing another method for carrying out the handrail rod structure of the present invention. The difference from the above embodiment is that the handrail rod 1 is different from the handrail rod receiving member 3. The end portion insertion portion is a handrail rod end rotating shaft portion 9 formed in a convex shape, and the basic components are the same. The feature of this embodiment is that strength is particularly required when the distance between the handrail support members 2 is large or when a metal having a high specific gravity is used for the handrail rod 1 by increasing the strength by increasing the thickness of each member. This is a point that can be dealt with.

  FIG. 9 is a perspective view showing an embodiment in which the present invention is implemented in a bag or the like for the purpose of preventing intrusion, and when the handrail bar of the present invention is installed on the upper stage of the bag 21 or the gate for the purpose of preventing intrusion, the handrail bar 1 is rotated. This is a case where the handrail bar of the present invention is used as an application for preventing intruders who are trying to get over the bag by using.

  In this case, by removing the stopper 4 and the stopper receiving portion 5 described in the above-described embodiment from the constituent elements, it becomes free to rotate as in the rotational direction 22, and when trying to get over, the degree of instability as a clue or foothold increases. The intrusion prevention effect is further increased. Because of such an effect, if the handrail bar of the present invention is installed in a cage other than a house, such as a school, a dangerous facility, an important public facility, etc., it is very useful as an intrusion prevention measure.

  If the connection part of the handrail support member is devised, it can be installed on the upper stage of the existing handrail bar. In this case, it is not necessary to remove the existing handrail, so there is a possibility that it can be installed without taking out waste.
