Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a covering device for roadside parking lots, singing platforms, etc., and more specifically, to a covering device in which a roof is attached to a support in a cantilevered manner.

[Conventional technology]

Generally speaking, as a covering device for roadside parking lots and song platforms, a support is erected at the back of the parking lot or song platform, and a roof that extends to the roadside is attached to the support in a cantilevered manner. A device is known that allows cars to enter and leave the parking lot, and to perform tasks such as watering and maintaining the singing platform from the road. However, with such a covering device where the road side of a parking lot or singing platform is open, there is a possibility that mud, stones, water, etc. thrown up by cars driving on the road may come into the parked cars or singing platform. There was an inconvenience.

Therefore, in the past, a covering body that surrounded the entire space such as a parking space was provided so as to be able to swing up and down using the pillars and walls at the back as swinging fulcrums to block flying objects (for example, in practice (Refer to Publication No. 147869, 1983).

[The problem that the idea aims to solve]

The conventional covering device configured as described above is useful in blocking flying objects from the road side, but if the height of the roof of the covering body is made sufficiently high, the position of the swinging fulcrum also becomes high, and the roof The rocking locus of the lower end of the vertical wall part hanging from one side edge may protrude significantly toward the road and come into contact with other objects, so there are severe restrictions on the installation location.

The purpose of this invention is to minimize the protrusion of the lower end of the vertical wall during rocking while increasing the height of the roof of the cover to a sufficient extent, to reduce restrictions on installation locations, and to make it easy to lift the cover manually. To provide a covering device that facilitates good performance of the lifting aid 7 when the lifting aid 7 is provided so that the lifting aid 7 can be lifted.

[Means to solve the problem]

The technical means of the present invention for achieving the above object is to construct a cover by vertically disposing a vertical wall on one edge of the roof, and on the opposite side of the roof from the side where the vertical wall is provided. A covering device whose edge portion is cantilevered to a support is provided with the configurations described in [A] to [C] below.

[B] The roof of the covering body is provided with an attachment part that is located below the ceiling forming surface of the roof when the lower end of the vertical wall is lowered to the lowest position in the intended covering position, and the lower end side of the attachment part is provided. is pivotally connected to the pillar at a swing axis position along the side edge of the roof.

[B] The cover body is provided with a lifting aid between the support column and the roof that applies a force acting on the cover body in a lifting direction, and is capable of vertically swinging around the swing axis. It is composed of

[C] The swing axis is positioned below a connection point of the lifting aid to the roof.

[Effect]

a. Since the wall is suspended and supported on the free end of the roof, when used as a covering device for a roadside parking lot or a music platform, by positioning the wall at the border with the road, it is possible to It is possible to prevent mud, stones, and water thrown up by cars traveling on the parking lot or the altar from inadvertently splashing into the parking lot or the podium.

b Since the pivot axis of the cover is set lower than the ceiling surface of the roof, the pivot axis should be set at the same level as the ceiling surface of the roof or higher than that. Compared to a structure in which the vertical wall is tilted, the protrusion of the lower end of the vertical wall toward the road side during swinging can be minimized.

c The pivot axis of the cover is set at a low position, and the difference in height between the connection point of the lifting aid to the column and the roof is reduced, so that the locus of the connection point of the lifting aid to the roof is aligned with the pivot axis. , since there is no significant difference when centering on any of the connection points to the pillars, the extension and contraction stroke of the lifting aid per swing angle of the roof is reduced, and therefore it is possible to cover a wide range of the lifting range. The biasing force is less attenuated as it crosses, making it easier to effectively exert the lifting assisting action.

[Effect of idea]

Therefore, the present invention can be used as a covering device for roadside parking lots and singing podiums, which can prevent flying objects from flying into the designated space, and can also reduce the protrusion of the lower end of vertical walls when lifted. This makes it possible to reduce restrictions on the installation location, and furthermore, it is easy to carry out lifting operations, making it possible to provide a very useful product.

〔Example〕

Next, an example of the present invention will be shown.

As shown in FIGS. 1 and 2, a plurality of pillars 2 are erected in the inner part of the parking lot A, and the cover body 1 is pivotally connected to the upper ends of these pillars 2. It constitutes a covering device installed in the

The cover 1 is constructed by vertical walls 4 hanging from one side edge of a roof 3 attached to the pillars 2 in a cantilevered manner, and the side of the roof 3 on which the vertical walls 4 are provided. is an attachment part 3 located on the opposite side edge and located below the ceiling forming surface 3A of the roof 3 in the intended covering position with the lower end of the vertical wall 4 lowered to the lowest position.
B, and the lower end side of the attachment portion 3B is pivotally connected to the support column 2 at a swing axis X position along the side edge of the roof 3.

The roof 3 and vertical walls 4 are constructed by attaching a series of wall-forming plate materials 6 that follow the external shapes of the roof 3 and vertical walls 4 to a frame 5 made of iron or light alloy (aluminum alloy, etc.). ing. Although the plate material 6 is made of self-extinguishing polycarbonate, it may also be made of acrylic.

The swing axis X of the cover 1 is set so that when the vertical wall 4 is displaced upward, an entrance a to the parking lot A from the road side is formed below the vertical wall 4. 3 along the longitudinal direction.

Further, between the roof 3 and the pillar 2, a cylinder serving as a lifting aid 7 that assists in lifting the roof 3 upward by the elastic force of a spring or air pressure is installed around the pivot connection points P and Q. It is interposed so that it can rotate freely.

The operating state of the cover device constructed in this way will be explained based on FIG. 3.

In other words, assuming that the cover 1 swings around the virtual swing axis X' shown in FIG.
The hypothetical swing locus R' of the lower end 4a of the vertical wall 4 is relatively large and tends to protrude outside of the parking lot A as shown in the figure, but in the present invention, it swings around the swing axis X. Therefore, the lower end 4a of the vertical wall 4
As shown by the swing locus R shown in the figure, the amount of outward protrusion is small.

The amount of elongation of the lifting aid 7 due to the rocking of the cover 1 is determined by the change in the distance between the connection points P and Q between the lifting aid 7, the cover 1, and the support column 2, that is, the roof side connection. Point P and column side connection point Q
It is determined by the amount of change in position. In other words, the swing locus r1 of the roof-side connection point P is a circular arc trajectory constrained by the swing axis X, and the support-side connection point Q
The difference between the locus r2 and the rotation center is the amount of elongation of the lifting aid 7. Therefore, the amount of elongation of the lifting aid 7 is determined from the roof side connection point P at the position indicated by the imaginary line in FIG.
A virtual connection point on the arc locus r′ with X′ as the center of oscillation
The amount of elongation is much smaller than the amount of elongation when swinging to P'. For this reason, if the lifting aid 7 is biased in the lifting direction by the elastic force of a spring or the elastic force accompanying the compression of air, the lifting aid 7 will vary depending on the amount of rocking of the cover 1.
Since the proportion of the amount of elongation is also small, the degree of decay of the biasing force of the lifting aid 7 is also small over a wide range of swinging range of the cover 1.

[Another example]

Another embodiment of the present invention will be shown below.

The covering body 1 shown in the above embodiment is provided as a covering device for a singing platform on the side of the road. In this case, the plate material 6 is
It is desirable to construct it from polycarbonate, which has excellent translucency.
