Specifically, in addition to the frame hinge-type joint and the tool-less base mounting technology already disclosed in the above device, the height adjustment function of the awning body and the front / rear length, left / right width, It is an object of the present invention to provide a wheelchair sunshade that has a function of adjusting a horizontal position and is convenient for a user.

  In order to solve the above-mentioned problem, a sunshade according to claim 1 is an sunshade used by being attached to an armrest strut and / or a backrest strut of a wheelchair, and can be attached to and detached from each other. The main body includes a plurality of frames bridged in a lateral arch shape above the seating portion, a light shielding sheet stretched on the frames, and each end of the plurality of frames is rotatable. A pair of receiving struts, and the plurality of frames can be bent in the front-rear direction of the wheelchair by a hinged joint disposed in the center in the longitudinal direction, and each of the pair of struts has a plurality of different inner diameters. The pipes are coaxially connected, and the support pillars expand and contract as the plurality of pipes enter and leave the adjacent pipes.

  The sunshade according to claim 2 is characterized in that, in addition to the features of claim 1, the base portion includes a plurality of pipes connected to each other, and a mounting plate that detachably receives a lower end mounting portion of the support column. The base portion is detachably attached to the wheelchair by winding the plurality of pipes around the armrest strut and / or backrest strut of the wheelchair with one or more bands.

  According to a third aspect of the present invention, in addition to the features of the first and second aspects, the sunshade includes a plurality of pipes that are coaxially connected to a part of the plurality of pipes of the base portion. When one of the pipes is inserted into and removed from the other pipe, the position of the mounting plate attached to the one pipe is changed in the axial direction of the one pipe.

  Hereinafter, embodiments of a sunshade for a wheelchair according to the present invention will be described with reference to the drawings. The sunshade of this embodiment (hereinafter referred to as “today sunshade”) is the sunshade according to claim 4, and has all the technical features according to claims 1 to 4.

As shown in FIG. 1, the sunshade includes a main body 1 and a base 2. The main body 1 has a configuration in which a light shielding sheet 12 is stretched on three arch-shaped frames 11, and the light shielding sheet 12 is expanded or closed in a bellows manner.
Hereinafter, the configuration and function of the present embodiment will be described along the four features of the sunshade.

  The first feature is a height adjustment mechanism of the main body 1. As shown in FIG. 6A, each end of the frame 11 is pivotally attached to a pair of struts 13, and the pivotally attached portions of the frame 11 and the struts 13 are rotated back and forth in the traveling direction of the wheelchair. Although the light shielding sheet 12 is configured to open and close in a bellows manner, the support column 13 has a structure in which three pipes A131, B132, and C133 having different inner diameters are connected coaxially. Here, when the pipe C133 enters and exits the pipe B132 and the pipe B132 enters and exits the pipe A131, the support column 13 expands and contracts. Each pipe is temporarily fixed by tightening two clips 134 at appropriate positions (FIG. 7). FIG. 1 shows a state when the column 13 is used with a short length, and FIG. 2 shows a state when the column 13 is used with the longest length. FIG. 3 shows a state where the light shielding sheet 12 is closed above the user's head when the sunshade is no longer needed.

  The above-described height adjustment mechanism is characterized by the convenience that the wheelchair user can operate in a sitting state. However, even when the sunshade is not used, the height adjustment mechanism can be used in combination with the frame folding mechanism described later to make the main body 1 compact. Storage is possible (FIG. 6B).

  The second feature of the sunshade is a frame folding mechanism. As shown in FIG. 4A, a hinge-type joint 111 is disposed at the center of the frame 11 in the longitudinal direction, and the three frames can be bent in the front-rear direction of the wheelchair at the zenith portion. 5A is a plan view showing the bending operation of the joint 111, and FIG. 5B is a front view showing the structure of the joint 111. FIG. As described above, by adopting the main folding mechanism and the height adjusting mechanism described above, the main body 1 can be stored in a compact manner. FIG. 4B is a front view of the main body 1 when the frame is closed and folded, and the support 13 is further shortened.

  The third feature of the sunshade is a simple attachment / detachment mechanism of the base portion 2. As shown in FIGS. 1 and 8, the base part is composed of an L-shaped pipe 21, an inner pipe 22, and a body mounting plate 23, and the L-shaped pipe 21 is attached to an armrest support column 31 of a wheelchair by bands 24 and 25. The inner pipe 22 is wound around the backrest support column 32 by a band 26. By this mechanism, the base part 2 can be attached and detached without using a tool, and there is no fear of damaging the wheelchair at the time of attachment or detachment.

  The connection method between the main body 1 and the base 2 is as shown in FIG. That is, the lower end mounting portion 135 disposed at the tip of the main body column 13 is fitted into the mounting portion 231 of the base unit mounting plate 23, the R pin 235 is inserted into the locking hole 234, and the column 13 is inserted into the main body mounting plate. Temporarily fix to 23.

  A fourth feature of the sunshade is an attachment position adjusting mechanism. With the structure and function of the base portion 2 described below, the sunshade can be adjusted in the mounting position in the three directions of front and rear length, left and right width, and horizontal.

  First, the adjustment of the longitudinal length will be described. As shown in FIG. 8 and FIG. 10, the base portion 2 has the lower pipe portion of the L-shaped pipe 21 and the inner pipe 22 connected coaxially, and the inner pipe 22 enters the lower pipe portion of the L-shaped pipe 21. Adjust the length of the front and rear by removing. Further, since the main body mounting plate 23 is temporarily fixed to the inner pipe 22 by the U-shaped bolt 234 and the wing nut 235 through the long groove 233 formed in the handle 232, the wing nut 235 is loosened and the main body mounting plate 23 is removed. The front / rear mounting position can be adjusted in the longitudinal direction of the inner pipe 22.

  Next is the position adjustment of the horizontal width. In the attachment of the main body attachment plate 23 to the inner pipe 22 using the U-shaped bolt 234 and the wing nut 235, the attachment position on the groove 233 is adjusted by moving the groove 233 in the length direction of the groove. It is possible to adjust the position of the left and right width.

  Further, when the wing nut 235 is tightened during the attachment, the horizontal position of the attachment portion 231 can be adjusted by rotating the plate 23 along the outer periphery of the inner pipe 22.

  As mentioned above, although the features and excellent points of the present invention have been described in the above embodiment, the present invention widely uses the words used in the claims of the utility model registration within the scope of the principle of the present invention. It can be extended to a practical meaning. For example, the specific shape and number of the frame 11 can be appropriately changed, and the mounting of the base portion 2 to the wheelchair is not performed by attaching the band to the backrest support column 32, but to the armrest support column 31. Only the attachment can be made, and the number of bands can be increased or decreased. Moreover, about the method of entering / extracting and temporarily fixing the inner side pipe 22 of the base part 2, it can replace with the fixing screw system of this embodiment, and can employ | adopt a clip system as shown in FIG. When this method is adopted, since the inner pipe 22 can be rotated when the clip 238 is tightened, there is an advantage that the adjustment of the mounting position in the horizontal direction is easier than in the present embodiment.
