Definitions

  • This invention relates to a corner canvas, a take-up shaft therefore, and a corner awning device, which are used for attractively covering corners of various buildings or framework structures.
  • movable awning devices are configured with a combination of: a canvas take-up device, which winds or unwinds a canvas that generally extends forward at an angle from a wall, on or from a canvas take-up shaft that is supported by an outer wall of a building, by means of a manual lever or electric motor, etc., and a canvas tension device, which connects bi-foldable swing arms and the like with a front bar fixed at the front edge of the canvas (for example, see the following patents 1-11, and publications 1 and 2). Many of them are used for sun-shielding or rain-shielding at terraces or along the perimeters of shops, or for ornamental purposes for buildings or shops, and various technical improvements and modifications have been made for such devices.
  • Fig. 15 (A) When the awning device is laid out along the perimeter of a building for an orthogonal corner shape as shown in Fig. 15 (A), a chamfered one as shown in Fig. 15 (B), at an obtuse angle as shown in Fig. 15 (C), and at an acute angle as illustrated in Fig. 15 (D), rectangular canvases (P) of various lengths are used around the perimeter that is orthogonal to either front wall W1, side wall W2, or oblique wall W3.
  • awning devices cannot effectively cover a corner space along the perimeter of the building, for example, a rectangular space Z1 shown in Fig. 15 (A), an acute-angled space Z2 shown Figs. 15 (B) and (C), and an obtuse-angled space shown in Fig. 15 (D).
  • the corner spaces Z1-Z3 shown in Figs. 15(A)-(C) can be covered if a canvas take-up shaft is installed at the corner of the front wall W1, and another canvas take-up shaft is installed by overlapping beneath or above the first take-up shaft, with the end of the take-up shaft projecting forward from the corner of the side wall 2 or oblique wall W3.
  • corners of various buildings are, in many cases, faced with roads in two directions, at an intersection, and are thus located in a place seen by many in general public and may be used favorably (such as effective advertising) in a business such as a shop.
  • the awning devices are set up at such an outstanding place without covering the corner spaces Z1 - Z3, or set up with cheap techniques, they lack technical effectiveness or usability as movable awning devices.
  • this invention provides a corner canvas and a take-up shaft therefore, and a corner awning device, which are able to deal with the above problem and further deal with various problems expected when providing the new products.
  • this invention provides a corner canvas having a substantially right-angled trapezoidal shape when extended, as a basic structure.

  • two of the corner canvases G1-G4 are extended at one side and the other side of the corner of outer walls W1 - W3 in side-to-side orthogonal relation as shown Fig. 16 (A), or they are extended in a layout as shown in Fig. 16 (B).
  • a corner of the building forms an obtuse angle or an acute angle
  • they are extended at an obtuse angle or an acute angle as shown Figs. 16 (C) and (D).
  • corner canvases G1 - G4 are able to effectively and attractively cover corner spaces Z1 - Z3 of the perimeter of the building. Further they are able to be marketed independently as a compatible corner canvas.
  • corner canvases G2 - G4 as described in the following sections (a1) - (a3) according to this invention, are provided as modified embodiments to improve the appearance by reducing a gap between the oblique sides of two canvases G2 - G4 when facing each other at the corner spaces Z1 - Z3.
  • corner spaces Z1 - Z3 of the perimeters of the buildings are covered attractively and effectively by installing two corner awning devices with said corner canvases G2 - G4 at the corner of front wall W1, side wall W2 or oblique wall W3, and extending them, as shown in Figs. 20 (A)-(C) and (AA)-(CC).
  • the conventional take-up shaft and a front bar must be installed with some part of the take-up shaft projected out from the corner of the building.
  • the canvas extension R2, R3 will be wound projecting from the corner of the building toward the corner space, and thus it will not only lose the decorativeness or appearance for the corner, but also lacks technical effectiveness and advantages as an awning device.
  • corner awning devices S1 - S6 comprising: a take-up device M1, M2 of the corner canvas G1 - G4, which is able to extend the corner canvas G1-G4 to the corner space Z1 - Z3 as shown in Figs. 16 (A)-(D), and to wind them without protruding out from the corner of the building; and a canvas tension device K1 - K6, which allows the corner canvas G1 - G4 to be extended and tensionally supported or to be compactly stored into a place by the wall.

  • the inner shaft 12, 12A, 12B is moved forward (sliding) while rotating the outer roller 13 to unwind the corner canvas when the corner canvas G1 - G4 is to be unwound.
  • the canvas take-up shaft J1 - J13 of this invention can be installed at the corner of the building without protruding from the corner, and also it can wind the corner canvas G1 - G4 without protruding from the shaft length of the canvas take-up shaft J1 - J13.

  • the imaginary space is affected by elasticity biasing force and tensioning force, tensile force caused by the canvas winding/unwinding operation, and thus it is expected that the canvas can be wound in unequal strength because it is pushed onto and partially contacted with the external perimeter surface of the inner shaft 12, 12A, 12B, or the canvas can be wound in a tapering form because it is affected by, for example, the obliquely rearward translation movement of the front bar 36, 36A.
  • the canvas extension R2, R3 is indirectly wound on the inner rotation shaft 12 via the slide belt 56 or the expansion and contraction belt 56A of the embodiments described above in sections (h7)-(h11), the forward/rearward movement of the outer roller is not hindered.
