(A) is a top view of a gate, (b) is a front view of a gate. It is a perspective view which shows the example of the operating method of a handle | steering-wheel. It is a cross-sectional view showing an example of a method for operating the handle. It is AA sectional drawing of FIG.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 3 shows a gate according to an embodiment of the present invention. In this gate, door bodies 1a and 1b are attached to left and right support columns 7a and 7b with hinges 8, and each door body 1a and 1b is rotated and opened to the site side. Each door body 1a, 1b has handles 2a, 2b, 2c, 2d attached to both sides on the door side. The handles 2a, 2b, 2c, 2d are provided at a higher position than before so that they can be operated without bending their waists. The height H of the handle from the ground is that an adult hangs his arm down and the elbow It is approximately the same height as the hand when bent at a right angle, specifically about 1000 mm.

  As shown in FIGS. 1 and 2, the handles 2a, 2b, 2c, and 2d are respectively attached to the bases 9a, 9b, 9c, and 9d, and the latch bolt 10 is attached to the base 9a on the site side of the right door 1a. Built-in, the handles 2a, 2b of the right door body 1a are provided with a spring so as to be swingable in the front-rear direction, and are latched by pulling the site-side handle 2a or pushing the road-side handle 2b. The bolt 10 is retracted. Further, a thumb turn 11 is provided in the handle 2a on the site side of the right door 1a, and a key hole 12 is provided in the handle 2b on the road. By operating these, the latch bolt 10 can be locked and released. A receiving hole 13 for the latch bolt 10 is provided in the base 9c on the site side of the left door body 1b. The handles 2c and 2d of the left door 1b are fixed to the bases 9c and 9d.

The four handles 2a, 2b, 2c, and 2d have the same form, a plate-like attachment portion 14 for attachment to the pedestals 9a, 9b, 9c, and 9d, and a suspension base that curves forward from the attachment portion 14 It has two upper and lower arms 3a and 3b extending sideways, and a rod-like grip 4 that is installed vertically at the tip of the arms 3a and 3b. As shown in FIG. 1, the arms 3 a and 3 b are curved in a substantially S shape in plan view so as to gradually move away from the doors 1 a and 1 b from the root part to the tip part, and the door body 1 a on the tip side. , 1b, and has an arcuate recess 20 facing it. As shown in FIG. 6, the upper arm 3 a is formed by scooping out the lower corner portion of the door body 1 a, 1 b side in an arc shape to form a finger hanging portion 5, and the lower arm 3 b is a door body. The upper corner portion on the 1a, 1b side is cut out in an arc shape to form a finger hook portion 5.
As shown in FIG. 1, the grip portion 4 is provided with a depression 15 on the side surface on the arm 3a, 3b side to make the door body 1a, 1b side narrower than the front side. It has a substantially jade-shaped cross-section that is bent and protrudes toward the door bodies 1a and 1b from the extended line 3b. The front surface of the grip portion 4 has a flat portion 6, and the arms 3 a and 3 b have the grip portion 4 so that the front surface of the front end portion is flush with the grip portion 4. It is connected to the side. A space S is formed between the door bodies 1 a and 1 b and the grip portion 4. The width W of the space S is an area where an elbow can be inserted, specifically 67 mm. Further, as shown in FIG. 2, the grip portion 4 protrudes upward and downward from the upper and lower arms 3a and 3b, respectively. The protruding length L of the grip portion 4 is 30 mm.
Further, in the handles 2a, 2b, 2c, 2d, as shown in FIG. 2A, a square hole 16 is formed between the upper and lower arms 3a, 3b, the grip portion 4, and the attachment portion 14. The size of the hole 16 is 46 mm in the horizontal dimension x and 55 mm in the vertical dimension y in front view.

According to the handles 2a, 2b, 2c, and 2d configured as described above, as shown in FIG. 4 (a), a portion protruding from the arms 3a and 3b of the grip portion 4 even with a load on the hand. The doors 1a and 1b can be easily opened by pulling on the wrist, elbow, forearm 17 and the like. Further, as shown in FIG. 4B, the forearm 17 or the like can be opened by inserting it vertically into the recess 20 on the rear side of the arms 3a and 3b.
