JP6171198B2 - Additional blocks for stairs - Google Patents

Description

  The present invention relates to a staircase in a building and a passage, and more particularly to an additional block for a staircase that is attached to the staircase in order to make the height of the step half and to make it easy to go up and down.

  Many stairs in current buildings and passages have a step (pick up) of about 18 cm and a tread depth of about 26 cm. Some private indoor staircases that have a limited area of use have a tread depth of 15 cm. In addition, some spectators' seats in sports facilities have a step (pick up) of about 22 cm. There may be no problem for healthy people, but elderly people with weak legs feel a heavy burden in daily climbing of indoor stairs. However, lowering the step (kicking up) without changing the depth dimension of the tread is to loosen the slope of the stairs, and the stairs in the buildings and passages become long and are often impossible to implement. On the other hand, it is effective to install an escalator in place of the stairs in the case of a passage with many users, but it is not an effective measure in a passage with few passers-by and a heavy economic burden. .

JP 2005-76432 A As a representative countermeasure technique, as shown in the above-mentioned document, it has been proposed that the step of stepping the staircase structure with the left and right feet is shifted by a half step. In the former, the height position of the step (kick up) is shifted by half a step, and the depth position of the tread is also shifted by a half step so that it can be easily moved up and down. In the latter case, the depth position of the tread is not shifted half a step, but the tread can be folded back to the existing state.

  However, in practice, it is necessary to modify the existing staircase, and the former method requires work such as cutting off a part of the staircase, which considerably increases the economic burden. Moreover, since the latter does not shift the depth position of the tread by a half step, the body shakes back and forth and left and right when ascending and descending, which may cause a fall accident. Therefore, there is a strong demand for a method that can convert an existing staircase to the former method as cheaply as possible.

  The problem to be solved by the present invention is to easily form a staircase that can be easily moved up and down by shifting the steps of the staircase back and forth and up and down half a step using the existing staircase. It is related with the additional block for stairs attached to. In particular, the block itself can be easily manufactured, and the transportation cost can be reduced by enabling compact stacking during transportation, and the installation cost can be reduced by facilitating installation, resulting in a significant increase in the cost of remodeling the stairs. Another object is to provide an additional block for staircases that can be reduced.

  Means for solving the above-mentioned problem of the present invention is based on two types of blocks, the depth dimension of the first block is half of the tread surface 2 of the existing staircase, and the height dimension is that of the existing staircase. It has the same dimensions as the kick-up part. The depth dimension of the second block is the same as the tread surface of the existing staircase, and the height dimension is half that of the raised portion of the existing staircase. The first and second blocks are hollow formed of six planes, each block is divided into two upper and lower members including intersections of three surfaces, and each can be coupled with a positioning pin and a positioning hole, An object of the present invention is to provide an additional block for a staircase in which a lower member is provided with a mounting hole to be fixed to a tread surface of an existing staircase.

  The effect of the present invention is that the two types of blocks are made into a hollow shape formed by six planes, so that when the blocks are made of wood-forming resin and metal casting, the blocks themselves can be easily manufactured at low cost. It can be manufactured and divided into two upper and lower members including the intersection of the three surfaces forming the block, so that it can be compactly overlapped during transportation, reducing transportation costs and facilitating installation. This reduces the construction cost and has the effect of blinding the mounting bolts so that they cannot be seen. As a result, the cost of remodeling the stairs can be greatly reduced.

FIG. 2 is an exploded perspective view showing the structure of the stair additional block according to the present invention. FIG. 3 is a partial perspective view showing the back surface of the staircase additional block of the present invention. FIG. 4 is a perspective view showing a stacked state of additional blocks for stairs according to the present invention.

  An embodiment for simplifying and realizing the staircase additional block of the present invention within a range not impairing the function thereof will be described.

1 is a perspective view showing a use state of an additional block for stair according to the present invention, FIG. 2 is an exploded perspective view showing a structure of the additional block for stair according to the present invention, and FIG. It is a fragmentary perspective view shown.
1, 2, and 3, 1 is an existing staircase, 2 is a tread surface thereof, and 3 is a kick-up portion. The depth dimension of the first block 6 constituted by the first upper member 4 and the first lower member 5 is half of the tread surface 2 of the staircase 1, and the height dimension is the same as that of the kick-up portion 3. The first upper member 4 is provided with a plurality of positioning pins 7, and the first lower member 5 is provided with a plurality of positioning holes 8 and attachment holes 9 at positions corresponding to the positioning pins 7. Yes. The depth dimension of the second block 12 formed by the second upper member 10 and the second lower member 11 is the same as that of the tread surface 2 of the stairs 1, and the height dimension is half that of the kick-up portion 3. A plurality of positioning pins 13 are implanted in the second upper member 10, and a plurality of positioning holes 14 and mounting holes 15 are provided in the second lower member 11 at positions corresponding to the positioning pins 13. . Reference numeral 16 denotes a handrail provided on the existing staircase 1.
[Action]

  The effect | action of the additional block for stairs of this invention shown to the said embodiment is demonstrated. A first block 6 composed of a first upper member 4 and a first lower member 5 is placed on the side of the existing staircase 1 near the handrail 16 so as to be in contact with the kick-up portion 3 on the tread surface 2, and is shown in the mounting hole 9. Can be attached to the existing staircase 1 using bolts that do not. A second block 12 composed of the second upper member 10 and the second lower member 11 is placed on the same tread surface 2 so as to be in contact with the kick-up portion 3, so as to be in contact with the kick-up portion 3, and a bolt (not shown) is used in the mounting hole 15. And attach to the existing staircase 1. In this state, the first upper member 4 is fixed to the first lower member 5 by engaging with the plurality of positioning holes 8 corresponding to the plurality of positioning pins 7, and a mounting bolt (not shown) is concealed from appearance. Never become. The second upper member 10 is fixed to the second lower member 11 by engaging with a plurality of positioning holes 14 corresponding to the plurality of positioning pins 13, and a mounting bolt (not shown) is concealed from appearance. There is nothing. If the first upper member 4 and the first lower member 5 and the second upper member 10 and the second lower member 11 are indoors, it is desirable to mold them with a wood-based resin material. If it is used, it is desirable to manufacture with iron casting. The alignment with the existing staircase can be performed by machining with a minimum area. It can be manufactured at low cost by such a manufacturing method. However, it does not exclude the production of blocks made of stone or concrete for reasons of design.

  FIG. 4 is a perspective view showing a state in which the first upper members 4 of the stair additional block of the present invention are stacked. The state in which the lower member 5 is stacked is substantially the same. As can be seen from FIG. 4, the first block 6 having a hollow structure can be compactly overlapped by being divided into the upper member 4 and the first lower member 5, and the cost during transportation can be greatly reduced. Needless to say, the above description is the same for the second upper member 10 and the second lower member 11 constituting the second block 12.

  The staircase additional block configured as described above is easy to manufacture with wood molding resin or casting, can hide the mounting bolts without ugly, and can be overlapped compactly, reducing the cost of transportation. Therefore, it is possible to change the existing staircase to a staircase that can be easily moved up and down at a minimum cost, and it is possible to advance measures for elderly people that have not advanced so far, and the social welfare effect is Extremely remarkable.
