Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a portable footrest to be carried on a trip such as an airplane or a train.

[0002]

[Problems to be solved by the prior art and the invention]

 When traveling in an airplane or train, sitting in a chair for an extended period of time causes swelling of the legs. As a countermeasure, various types of portable footrests have been proposed since the feet become easier if the feet are raised slightly.

[0003] For example, Japanese Utility Model Laid-Open No. 3-104440 discloses a footrest composed of an inclined footrest and a leg plate supporting the footrest, which is disclosed in Japanese Utility Model Registration No. 3049282. Discloses a simple folding chair type footrest. Japanese Utility Model Laid-Open No. 61-147050 discloses an assembly box type footrest.

[0004] A footrest of the footrest board type needs to maintain a predetermined height and strength by the plate itself, and if the predetermined strength is to be maintained, the footrest becomes an appropriate weight and is not necessarily suitable for carrying. . The folding chair type also has a problem in weight reduction. Further, the box-shaped footrest has difficulty in assembling work, and the whole is plate-shaped like the above-mentioned types, so that there is a problem in carrying weight.

Accordingly, the present invention proposes a novel footrest that is formed by rods except for the footrest part, thereby reducing the weight of the portable body and being easy to carry.

[0006]

[Means to solve the problem]

 The portable footrest according to the present invention is a double frame including a rectangular frame and a U-shaped frame, and an end of the U-shaped frame is positioned in an axial direction parallel to one side of the non-double portion of the rectangular frame. It is pivotally connected and has a foot frame and an upright frame with both frames openable and closable about one side of the non-duplex portion as a central axis, and extends with the foot frame and the upright frame opened at approximately right angles. Sometimes, the inside of the upright portion of the rectangular frame is connected to the leading portion of the U-shaped frame, and the hypotenuse is separated from the leading portion at the time of folding and folded along the inside of the upright portion of the rectangular frame. And a footrest plate installed between the hypotenuse bodies.

[0007]

[Action]

 When the rectangular frame and the U-shaped frame (foot frame and upright frame) are opened at approximately right angles and connected by oblique bodies to form a triangular structure as a whole, a solid framework is formed. The foot is used on a footrest board that is erected on the hypotenuse. Also, when carrying, when the oblique body is folded and the foot frame and upright frame are closed, the whole is in a single plate state, and it can be easily carried as baggage by grasping any rod part of the frame. .

[0008]

【Example】

 Next, the most preferred embodiment of the present invention will be described. The footrest shown in the embodiment is formed by a vertical frame 1, a foot frame 2, an oblique body 3 formed by combining or processing a rod having a rectangular cross section formed of a lightweight aluminum extruded material, and a thin plate member. And a pin body 5 formed from a rod member.

The upright frame 1 is a rectangular frame and includes left and right upright bars 11, an upper side bar 12 connecting the upright bars 11, and a lower single bar 13, and is provided with a pin through hole 14 described later. . The foot frame 2 is provided with a side rod 21 and a front rod 22 connecting the side rods 21 in parallel with each other in a U-shaped frame. The side rod 21 and the front rod 22 are connected to the vertical rod of the vertical frame 1. The end of the side rod 21 is pivoted about the center of the longitudinal axis of the lower side rod 13 so as to be along the outer circumference of the upper side rod 11 and the upper side rod 12. It is possible to take the form of Further, a through hole 23 for a pin, which will be described later in particular, is formed, and a connecting recess 24 is formed in the front rod 22.

The footrest plate 4 is provided with a fitting connection shaft 42 and an urging connection shaft 43 at the centers of both ends of a footrest plate body 41 having appropriate strength. The fitting connection shaft 42 is a rectangular shaft or a star shaft, and the urging connection shaft 43 has an appropriate length (which can be installed and removed between the hypotenuse rods 3 described later, and The length of the flange 44 does not protrude outward from the main body 41.

The hypotenuse body 3 includes an upper rod 31 and a lower rod 32, a part of which overlaps with each other, and is pivotally connected at a point of overlap so that the upper rod 31 can be folded. The lower rod 32 pivotally connected to the inside of the portion and disposed inside the upper rod 31 has a length such that the tip of the lower rod 32 can be fitted into the coupling recess 24 of the front rod 22 when the entire hypotenuse body 3 is extended. It is assumed that. Further, through holes 33 and 34 for pins which penetrate both at the time of extension polymerization are formed. In addition, an installation structure of the footrest plate 4 is provided inside the lower rod 32, and the fitting connection shaft 42 is in parallel with the hypotenuse body 3 inside one of the lower rods 32. A plurality of fitting recesses 35 having a shape capable of selectively fitting into a parallel state with the foot frame 2. A connecting shaft 43 is provided inside the lower rod 32 facing the fitting recess 35. And an insertion through-hole 36 having an inner diameter corresponding to.

The pin body 5 is attached to an upper end portion of the lower rod 32 with an appropriate cord body 51. A description will now be given of the assembling of the footrest in use. First, the standing frame 1 is erected, the foot frame 2 is opened to be horizontal, the oblique body 3 is extended, the lower end of the lower rod 32 is fitted into the connecting recess 24, and the pin 5 is inserted into the through hole 33. , 34, the upright frame 1, the foot frame 2, and the oblique body 3 are integrated. Then, the urging connection shaft 43 of the footrest plate 4 is inserted deeply into the insertion through hole 36 against the urging force of the compression ridge 45, and the footrest plate body 41 is When the fitting connection shaft 42 is inserted at the parallel position, the footrest plate 4 does not come off due to the urging force of the compression ridge 45 and is attached to the hypotenuse body 3. Therefore, when the foot frame 2 is positioned on the floor in front of the chair, the foot frame 2 can be used as a footrest.

In order to shift to the portable state, the footrest 4 is temporarily detached from its fitting connection shaft 42 from the fitting recess 35, and the footrest plate main body 41 is again placed at a position parallel to the lower rod 32. Then, the pin body 5 is pulled out from the through holes 33 and 34, and the oblique body 3 is folded and attached to the inside of the vertical rod 11 of the vertical frame 1. When the foot frame 2 is attached to the outer periphery of the upright frame 1 and the pin body 5 is inserted through the through holes 14, 23, and 34, the whole is integrated into a plate frame shape.

[0014]
