It is a side view which shows a mode that the wall surface of a building is constructed using the work gondola of FIG. It is a rear view which shows a mode that a wall surface of a building is constructed using the work gondola of FIG. It is a rear view showing a working gondola according to another embodiment of the present invention.

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

  The working gondola 1 shown in FIGS. 1 to 3 is configured to be suspended and lifted from the upper part such as a roof or a roof of a building by a wire 2 as a hanging member. In addition, although a building can be used as the middle-high-rise apartment house, for example, it is not limited to this, It is employable as any building which has a wall surface.

  The working gondola 1 includes a floor 3, a support 4, a handrail 5, and a belt 6. The extending direction of the long side of the floor 3 whose plan view viewed from above is rectangular is the width direction (left and right direction) of the working gondola 1, and the extending direction of the short side is the depth direction of the working gondola 1. (Front-back direction). Further, the extending direction of the support 4 orthogonal to the floor 3 a of the floor 3 is taken as the height direction of the working gondola 1.

  The floor 3 is provided with a horizontal floor 3a on which a user (operator) can ride. In the present embodiment, a slide hole 3 b extending in the width direction of the working gondola 1 is formed in the plate member constituting the floor surface 3 a.

  Four wheels 3 c are provided on the lower surface of the floor 3. Thus, the working gondola 1 can be easily moved in the state of being placed on the ground. The four wheels 3 c are provided at four places which are corners of the lower surface of the floor 3.

  Guide rollers 7 are respectively provided on the front side and the rear side on both sides in the width direction of the floor portion 3. The guide roller 7 rotates the guide roller 7 when raising and lowering the working gondola 1 with the front surface of the working gondola 1 in contact with the wall surface S, which is the outer wall surface of a building, for example. Damage can be prevented. Therefore, the guide roller 7 on the front side projects the most to the front in the working gondola 1, and the guide roller 7 on the rear side protrudes the most to the rear in the working gondola 1.

  In this example, by providing the guide rollers 7 on the front and back sides of the working gondola 1, as shown in FIG. 2, not only the wall S to be constructed but also the wall S 'facing the wall S Damage can also be prevented.

  The support | pillar part 4 is a prismatic support | pillar support member each provided upright at the edge part of the width direction both sides of the floor part 3. As shown in FIG. The support 4 extends perpendicularly to the floor 3a. Each support column 4 in this example is configured of one support column member, but is not limited to this. For example, a plurality of support members installed at intervals in the depth direction or width direction of the floor 3 You may comprise by a support member.

  Moreover, in this example, the roller holding part 4a is provided in the upper end part of each support | pillar part 4 of each right and left, and the guide roller 8 is each provided in the front side and back side of the said roller holding part 4a. The guide roller 8 has the same function as the guide roller 7 provided on the floor 3. That is, when the work gondola 1 moves up and down while the guide roller 8 contacts the wall surface S or the wall surface S ′ facing the wall surface S, the wall surface S is prevented from being damaged. In addition, the guide hole 4b for letting the wire 2 pass is formed in the roller holding part 4a of this example.

  The handrail portion 5 is formed of a rod-like member extending in the width direction in parallel (horizontally) with the floor surface 3 a at a predetermined height above the floor portion 3. Both ends of the handrail 5 are connected to the left and right columns 4. More specifically, both ends of the handrail portion 5 are fixed to a handrail support portion 4c projecting forward at an intermediate position in the height direction of each of the column portions 4. In addition, it is preferable that the height from the floor surface 3a of the handrail part 5 is a height comparable as the position of a user's waist.

  A lower wall 4 e is provided at the lower part of the support 4 via a lower wall support 4 d projecting forward. Thereby, even when the user slides the foot, for example, the foot can hit the lower wall 4 e and the foot can be prevented from dropping forward from the floor surface 3 a. The lower wall 4e may be provided on the rear side.

  In the present embodiment, the handrail portion 5 is provided only on the front side of the working gondola 1 and is configured to be gripped by the user during work and when moving on the floor surface 3a. In addition, the handrail portion 5 can prevent the user from falling to the front side. In addition, in the working gondola 1 of this example, it is possible to reliably prevent a drop in any direction by surrounding the trunk of the user with the belt 6 connected to the handrail 5.

  The belt portion 6 is a belt-like member connected to the handrail portion 5 and holding the trunk portion of the user. In this example, the belt portion 6 surrounds the entire circumference of the user's torso portion, and an annular portion configured to be detachable by the front connector portion 6b, and both left and right sides connecting the annular portion to the handrail portion 5. And a connecting portion. The belt unit 6 is configured to be removable from the user and the handrail unit 5. The belt portion 6 in this example is provided with an annular connecting portion 6 a which is detachable and slidable with respect to the handrail portion 5. As a result, the user can safely move on the floor 3 a while keeping the belt 6 wound around the trunk connected to the handrail 5. Further, the belt portion 6 is preferably configured to be wound around the waist, among the trunks of the user.

  In the present example, the handrail portion 5 is provided only on the front side of the working gondola 1, but the handrail portion 5 may be provided only on the rear side. In this case, the belt portion 6 connected to the handrail portion 5 is disposed on the opposite side to the present embodiment. That is, the handrail portion 5 is provided only on the rear side of the working gondola 1, and the belt portion 6 is provided on the front side. Thus, the handrail portion 5 can prevent the user from falling to the rear side, and the belt portion 6 can prevent the falling in directions other than the rear side.

  Thus, by providing the handrail portion 5 on only one of the front side and the rear side and connecting the user and the handrail portion 5 with the belt portion 6, the depth D is designed to be smaller than in the case where handrails are provided on both sides. can do. Thereby, it becomes possible to use also in the narrow space where distance C (refer to Drawing 2) between wall surface S which is construction object, and wall surface S 'of the next building which counters the wall surface S concerned is narrow. The depth D of the working gondola 1 is preferably 50 cm or less. More preferably, the depth D is 27 cm or more and 33 cm or less.

  The working gondola 1 of the present example further includes a chair unit 10 that allows the user to sit in a substantially upright posture. It should be noted that sitting down with the substantially upright posture means that the upper body above the waist (center line of the abdomen to the chest) and the lower body below the waist (center line of the thigh) are approximately 90 when viewed from the side Instead of sitting in a crooked state at a large angle, it is possible to sit close to an upright posture where the hips and knees are not bent so that the upper body and the lower body are substantially straight as viewed from the side It is meant. For example, by sitting like a unicycle or a bicycle saddle, it is possible to easily sit while maintaining a substantially upright posture. Since the knee does not project forward largely like when sitting in a general chair by sitting in this almost upright posture, the user can sit even if the depth of the space in the working gondola 1 is narrow it can. In addition, although the state in which the lower back and knees are slightly bent or the lower body is slightly forward from the upper body is also included, in either case, the front end of the working gondola 1 (in this example, the guide roller It is possible to sit so that the user's knee does not come out more than the front end of 7 and 8).

  The chair portion 10 includes a saddle portion 11 forming a seating surface, and a columnar saddle support portion 12 provided below the saddle portion 11. The saddle portion 11 has a shape that can be straddled like a bicycle saddle, and the width of the front side is narrower than the rear side. The shape of the saddle portion 11 is not particularly limited as long as it can sit while maintaining a substantially upright posture, and, for example, the rear side is narrowed (thinned) in the same manner as the front side of the saddle portion 11 It may be shaped like a unicycle saddle.

  In the present embodiment, the saddle support portion 12 is configured to be able to freely change the height of the saddle portion 11. As a result, the height of the seat can be adjusted to an appropriate height according to the user, so it is possible to work with an appropriate posture with less burden on the body. The height of the seat can be adjusted to include 60 cm to 90 cm from the floor.

  The saddle support 12 is preferably configured to be slidable along the slide hole 3 b of the floor 3, that is, in the width direction of the working gondola 1. With such a configuration, it is possible to perform the work in the working gondola 1 in a wide range while sitting on the chair portion 10. The slide mechanism is not particularly limited, but in the present example, a shaft portion passing through the slide hole 3b of the floor 3 and a flange portion provided at the tip of the shaft portion in the lower portion of the saddle support 12 And 12a are provided. The outer diameter of the flange portion 12a is larger than the width of the slide hole 3b, thereby preventing the shaft portion of the saddle support portion 12 from coming out of the slide hole 3b. With such a configuration, the saddle support 12 is slidable along the slide hole 3b. Thus, the user can change the chair unit 10 to a desired position by sliding the chair unit 10 in a state of straddling the saddle unit 11 or standing up to the side of the saddle unit 11.

  In the present embodiment, a restricting portion 13 for restricting the wobbling of the saddle support portion 12 (swing displacement with the lower end portion of the saddle support portion 12 as a fulcrum) is provided. The restriction portion 13 includes a ring portion 13a surrounding the upper portion of the saddle support portion 12 from the outside, a cylinder portion 13b surrounding the handrail portion 5 from the outside, and a connecting portion 13c connecting the ring portion 13a and the cylinder portion 13b. There is. The restricting portion 13 can prevent the problem that the saddle support portion 12 is inclined with the lower end portion as a fulcrum at the time of operation, for example, and the saddle portion 11 is displaced to the front, rear, left, and right. In this example, the cylindrical portion 13b is configured to be slidable with respect to the handrail portion 5, and the restricting portion 13 can also be slid according to the movement (slide) of the chair portion 10 along the slide hole 3b. .

  The saddle support 12 may be provided with a stopper function so that the chair 10 does not slide during work. Although the configuration of the stopper function is not particularly limited, for example, when the user puts weight on the saddle portion 11 and sits down, the rubber surface of the bottom surface of the saddle support portion 12 abuts on the floor surface 3a to cause friction. The resistance can be increased, and can not slide in the width direction. In this case, when the user does not put weight on the saddle portion 11, the stopper function does not work, and the user can slide in the width direction.

  By providing the chair portion 10, the physical burden on the user can be reduced as compared with the case of working in the upright state. Also, for example, when the user works while straddling the chair portion 10 with the foot attached to the floor surface 3a, the weight is supported by the chair portion 10 even when the foot is slid from the floor surface 3a Can work more safely.

  When the construction work of the wall surface S of the building is performed using the working gondola 1 of this example, as shown in FIGS. 1 and 2, the front side of the working gondola 1 on which the handrail portion 5 is provided is a wall surface It is arranged along the wall S so as to be located on the S side. That is, the width direction of the wall surface S is parallel to the width direction of the working gondola 1, and the depth direction of the working gondola 1 is perpendicular to the wall surface S.

  The working gondola 1 is configured to be able to move up and down. That is, the user can freely raise or lower the working gondola 1 while stopping on the working gondola 1 and stop the work gondola 1 at a desired height. As a method of lifting and lowering, for example, there is a method of operating a winding device (not shown) of the wire 2 by the operation of a remote controller (not shown) connected by wire or wireless, but it is not limited thereto. In this case, the winding device for the wire 2 may be provided inside the working gondola 1 or may be provided outside the working gondola 1 such as a rooftop.

  FIG. 4 shows a working gondola 20 according to another embodiment. In addition, the same code | symbol is attached | subjected in the figure to the part in which the basic function is the same as embodiment mentioned above, and description is abbreviate | omitted.

  The working gondola 20 according to the present embodiment is configured to be suspended and held by a single wire 2 provided on the central axis of the working gondola 20. The left and right support portions 4 are connected by a support connecting portion 4 f provided at the upper end portion thereof. The wire 2 is connected to the support 4f.

  The building which concerns on this invention is not limited to the structure of embodiment mentioned above, It is possible to implement | achieve with various structures in the range which does not deviate from the content described in the claim. For example, a plurality of handrails 5 may be provided at different heights, or an auxiliary post or the like connecting the handrail 5 and the floor 3 may be provided. In addition, handrails may be provided on both the front side and the rear side. In this case, it is preferable to use one of the front and rear handrails as an auxiliary handrail and a thin plate-like member or the like that has little influence on the depth of the gondola. In addition, the working gondola according to the present invention includes a device for a worker to perform work and the like on the floor, and is usually held by a suspension member. However, if it is a range which does not deviate from the meaning of the present invention, even if it is not held by the suspension member, it may be held by other members.
