Abstract

<P>PROBLEM TO BE SOLVED: To provide a storage bench also used as a guard fence, which enables a speed of a seating part to be easily set approximately constant when the seating part is automatically returned to a raised state as a normal state from a horizontal state in use, and which enables an urging force to be easily adjusted even if the urging force is decreased. <P>SOLUTION: Even if the urging forces of respective urging means for automatically returning the seating part 2 to the normal state from a use state are different from one another, the urging forces of the urging means can be easily set approximately constant only by loosening an adjusting screw 9 for locking one end of the urging means, when the urging force of the urging means is too strong, and performing the tightening adjustment of the adjusting screw when the urging force of the urging means is too weak. Furthermore, even if the urging force of the urging means is decreased because the storage bench 10 also used as the guard fence is repeatedly used, the urging force of the urging means can be adjusted without the disassembly of the storage bench 10. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a collapsible protective fence-use storage bench in which a protective fence used in a sidewalk, a bus stop, a park or the like has a bench function.

  On the shoulders of parks and sidewalks, there are protective fences that are equipped with bench functions that allow the elderly to sit down when they are tired. Conventionally, as a protective fence combined bench, for example, Patent Document 1 discloses a protective fence in which a seat portion constituting a bench is normally stored and held in a frame of the protective fence to protect a person from entering a vehicle and ensure safety. In addition, it is a protective fence combined bench that forms a simple bench by deploying the seat horizontally during use, and is attached to a support shaft mounted between a pair of support columns and rotated with respect to the support columns. The movable seat is automatically returned from the horizontal state during use to the normal retracted state by the biasing force of the torsion spring that is a biasing means fitted on the tip of the spindle, and the seat springs up vigorously. A protective fence combined bench equipped with a hydraulic pump type torque damper mechanism for quietly returning to a retracted state while suppressing the above is disclosed.

JP-A-9-78543

  However, it is difficult to make the urging force of the torsion springs the same in each of the fences that protect the fence, and even if it is equipped with a hydraulic pump type torque damper mechanism, the seat that automatically returns from the horizontal state during use to the normal standing state The speed is difficult to be constant. In addition, even if the urging force of the torsion spring is adjusted so that the speed of the seat that automatically returns to the standing state is constant and the bench for the protection fence is formed, the urging force of the torsion spring is reduced by repeated use. In each case, it was necessary to disassemble the protective fence bench and adjust the urging force of the torsion spring.

  The present invention has been made to solve the above-described problems, and can easily make the speed of the seat portion when returning automatically from the horizontal state during use to the normal standing state, substantially constant, It is intended to provide a protective fence / storage bench that can easily adjust the urging force even when the urging force decreases.

  In order to achieve the above object, the present invention is configured as follows. That is, the protection fence / storage bench according to the present invention includes a fence body in which a support frame is attached between two support columns standing on the ground, and a pivot that is rotatably attached to the support frame. And a damper with which the pivot is engaged, a seat attached to the pivot, and a biasing means which is locked to the pivot and applies a biasing force to rotate the seat upward. Under normal conditions, the urging force of the urging means is stored and held in a standing state in a frame constituted by the support columns and the support frame of the fence body, and in use, the urging force is rotated downward by a force exceeding the urging force of the urging means. When it is moved to the horizontal state and the force applied during use is removed, the speed at which the seat returns to the normal state by the biasing force of the biasing means is kept low by the damper, and one end of the biasing means is locked. The adjusting screw adjusts the biasing force of the biasing means from the outside. And it is characterized in that it made possible.

  According to the protective fence / storage bench according to the present invention, even if the urging force of the urging means for automatically returning the seat portion from the use state to the normal state differs for each urging means, one end of the urging means is engaged. If the biasing force of the biasing means is too strong, loosen the adjustment screw to be stopped, and if it is too weak, the biasing force of the biasing means can be made substantially constant simply by tightening adjustment. Furthermore, even when the protective fence / storage bench is used repeatedly and the urging force of the urging means decreases, the urging force of the urging means should be adjusted without disassembling the protective fence / storage bench. Can do. Therefore, a desired speed can be obtained when the protective fence / storage bench returns to the normal state without precisely designing and manufacturing the biasing force of the biasing means and the damping force of the damper.

BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to FIGS.
FIG. 1 shows an embodiment of a protective fence / storage bench according to the present invention, and is a front perspective view of the protective fence / storage bench. Reference numeral 1 denotes an upper U of a pair of left and right columns 11 erected on the ground, which is integrally coupled with an upper ledge 12 to form an inverted U-shape, and a lower ledge 13 is passed between the ledges 11 and coupled. 12 is a fence body that constitutes a column protection fence / storage bench 10 in which a vertical beam 14 is passed to the center part of 12 and the center part of a lower side ridge 13. A rotating part K is fixed to each of the upper surfaces of the lower ridges 13 divided into two by the vertical beam 14, and a seat part 2 on which a person can sit is rotatable on each rotating part K. It is attached. In addition, the seat portion 2 has an arm 22 that is pivotally attached to the pivot portion K, and a seat plate 21 that is fixed to the arm 22 and has a substantially flat surface standing in a frame formed by the fence body 1. The state is stored and held in the normal state.

Here, the support column 11 and the upper stage reed 12 may be combined separately or may be formed by bending a single tube. Moreover, the material of the support | pillar 11, the upper stage horizontal rail 12, and the lower level horizontal rail 13 will not be specifically limited if the intensity | strength as a protective fence is satisfied, Metals for structures, such as steel, aluminum, stainless steel, titanium, and zinc You may use it suitably from materials. Further, the shape is not limited to a rectangular cross section as shown in FIG.
The seat plate 21 has three rectangular plates attached to the arm 22 at substantially equal intervals. The material of the seat plate 21 can withstand the load when a person is seated or put a load. Although there is no particular limitation, synthetic wood obtained by kneading and molding wood chips and the like with a synthetic resin is excellent in weather resistance and has the same feel and appearance as natural wood, so it is preferably used. It is done.

  FIG. 2 is a front perspective view showing a usage state of the seat portion 2 of the protective fence / storage bench 10 shown in FIG. 1. By applying an external force to the seat plate 21 and pulling it forward, the seat portion 2 is rotated to a horizontal position with respect to the ground, and when a person is seated, the seat portion 2 is held in a horizontal state. When the person stands up and the external force is removed, the seat portion 2 is automatically stored in the frame formed by the fence body 1 by the structure of the rotating portion K described later. Therefore, since there is no portion protruding from the fence body 1, there is no hindrance to traffic, and there is no need for a person to lift the seat 2 and return it to the standing (retracted) state.

  3 is a partial perspective view seen from the back side of FIG. 1 and shows a state in which the rotating part cover K1 which is the exterior of the rotating part K shown in FIG. 1 is removed, and FIGS. 4a) and 4b). These are the rear view and front view of the principal part of FIG. The structure of the rotation part K and the rotation mechanism of the seat part 2 will be described with reference to FIGS. 3 and 4 a) and b).

  The rotating part K is attached to the upper surface of the lower horizontal rail 13 with the support frame 3 having a C-shaped cross section open upward, and both ends of the support frame 3 are provided with bearings (not shown). A support plate 5 that supports the pivot 4 is fixed. Both ends of the support plate 5 are inserted and supported, and a flange 41 is fixed to a central portion of the pivot 4 that is supported in parallel with the pivot 4. A flange 41 is secured to the end of the pivot 4. A damper 6 that suppresses the rotational speed of the pivot 4 is engaged, and the damper 6 is attached to the support plate 5. Further, a torsion spring 7 as an urging means is wound around the pivot 4, and one end of the torsion spring 7 is locked by the locking portion 42 fixed to the flange 41, and the other end is supported. It is slidably sandwiched by a torsion spring holding portion 8 including two flat plates 81 and 81 fixed so as to be orthogonal to the frame 3 and a flat plate 82 that is passed and fixed to the flat plates 81 and 81. The side of the support frame 3 to which the torsion spring holding portion 8 is fixed is provided with a notch, and the screw head of the adjustment screw 9 screwed to the flat plate 82 is viewed from the outside. The tip is in contact with the end of the torsion spring 7. Note that the base portion of the arm 22 constituting the seat portion 2 is fixed to the pivot 4. Further, an arm stopper 51 for stopping the rotation of the arm 22 at the standing position and the substantially horizontal position is fixed to the support plate 5.

In a normal state, the seat portion 2 is held in an upright state, and when an external force exceeding the biasing force of the torsion spring 7 is applied, the seat portion 2 is rotated to a substantially horizontal state, and a person or the like is seated on the seat plate 21. It will be in use. When a person stands up, the normal seat 2 is automatically returned to the upright state by the biasing force of the torsion spring 7. At that time, if the speed at which the seat 2 returns to the normal state is too fast, it may be dangerous because of contact with a person or a finger or the like being pinched. 6 is installed.
Furthermore, since the urging force of the torsion spring 7 gradually weakens as the number of uses of the seat portion 2 increases, it is assumed that the state does not automatically return to the state. At that time, the tightening spring 7 can be adjusted by tightening the adjusting screw 9 that the screw head is looking into from the outside, so that the rotating portion K can be removed from the lower side reed 13. This is preferable because the biasing force of the torsion spring can be adjusted in a short time. Even when the protective fence / storage bench 10 is manufactured, the speed at which the seat 2 is automatically returned from the use (substantially horizontal) state to the normal state (stand-up state) is different for each of the protective fence / storage benches 10. In this case, it goes without saying that these speeds can be adjusted to be substantially the same by loosening or tightening the adjusting screw 9 from the outside.

  In the embodiment of the protective fence / storage bench 10 described so far, the lower ledge 13 and the support frame 3 are separated from each other, and the support frame 3 is fixed to the upper surface of the lower ledge 13. The invention is not particularly limited to this embodiment. For example, the support plate 5 and the torsion spring holding portion 8 can be directly fixed to the upper surface of the lower ledge 13 so that the lower ledge 13 and the support frame 3 are integrated to have the same function as the above-described embodiment. It is.

It is a front perspective view which shows the Example of the protection fence and storage bench concerning this invention. It is a front perspective view which shows the use condition of the protection fence combined storage bench concerning this invention. FIG. 2 is a partially omitted perspective view seen from the back side of FIG. 1. It is the rear view and front view of the principal part of FIG.
