Description

[Detailed description of the invention] This invention relates to the frame of a handrail that is attached to the outdoor side of a window, and is composed of horizontal bars, vertical bars, caps, and fixed bars that are integrated with or separate from the horizontal bars. When shipped, it can be transported in a thinly folded state, and when installed, it can be easily erected.

Each rail that makes up the handrail framework is now formed from an extruded aluminum profile, which is either fabricated and provided ready for immediate assembly, or It is provided in condition.

In particular, the prefabricated frame can be installed by a so-called do-it-yourself worker without leaving the window to the hands of a specialist.

However, the ones that had already been assembled were large and bulky, making transportation extremely inconvenient.

Focusing on the above points, this device was transformed into the most convenient state for transportation, and when installed on a window, it was constructed so that it could be reliably restored to an upright state with a simple operation. To explain this, in the drawings, 1 is a horizontal bar, 2 is a vertical bar, and 3 is a cap, and the horizontal bar 1 is a convex part in the middle of the strip plate along the longitudinal direction, as shown in Figures 1 and 4. It has strips, and is further provided integrally with a fixed bar 4 having a stepped portion forward from the upper end of the strip plate.

The horizontal bar 1' shown in FIG. 2 is a strip-shaped plate without the fixing bar 4, and the fixing bar 4' is a separate strip-shaped plate.

The vertical bar 2 has a U-shaped cross section, is provided with a screw pocket 5 along its entire length in the longitudinal direction at its internal center, and is bent into an L-shape.

The Kasagi 3 has a substantially rectangular cross section, and has a retaining groove 6 on the back into which the upper end of the vertical bar 2 fits, and nuts 1 and 1 for tightening the mounting arms 9.
0 is fitted into the locking groove 7, and a support piece 8 that hangs down from one side edge of the engagement groove 6 is provided.

Therefore, the lower end surfaces of a plurality of vertical bars 2 are fixed with screws 11 at equal intervals in the longitudinal direction of the horizontal bars 1 or 1'.
A washer 12 is interposed on the end surface in contact with the horizontal crosspiece 1 to fix it.

Each vertical bar 2 is fixed to the horizontal bars 1, 1' with a single screw 11, so if a pressing force is applied to the vertical bar 2 in the longitudinal direction of the horizontal bars 1, 1', the vertical bar 2 can be knocked down. I can do it.

Note that the fixed bars 4 provided at the horizontal bars 1 and Ikkyu are elastically pressed against the upper surface of each vertical bar 2.

Further, the separate fixing bar 4' is screwed to the bent horizontal portion of the vertical bar 2 when the frame of the handrail is attached to the window.

Next, the upper end of each vertical bar 2 is inserted into the engaging groove 6 of the cap 3, and the vertical bar 2 and the support piece 8 are fixed with pop rivets 13.

The pop rivet 13 and the screw 11 are parallel to each other, and each vertical bar 2 can be tilted by moving the cap 3 or the horizontal bar 1 in parallel.

This invention has the above structure, and when the horizontal beams 1, vertical beams 2, and caps 3 are assembled, each vertical beam 2 stands upright as shown in the front view of FIG. As shown in the plan view of FIG. 6 and the front view of FIG. 7, by moving the cap 3 parallel to the horizontal beams 1, each vertical beam 2 can be tilted and folded thinly.

At this time, if the fixed bar 4 is integrally formed with the horizontal bar 1, the fixed bar 4 is floated by the vertical bar 2 as shown in FIG. When it stands upright, the fixed crosspiece 4 presses against each vertical crosspiece 2 by restoring force and maintains the upright state.

In addition, as shown in FIG. 2, when the fixed bars 4 are provided separately, when each vertical bar 2 is installed in an upright window, it is possible to prevent the vertical bars 2 from tipping by fixing them to each vertical bar 2 with rivets or the like. Furthermore, if it is attached to a window via the attachment arm 9 as shown in FIG. 1, the vertical bar 2 will be reliably held upright without being tilted.

Therefore, a handrail frame with a structure based on this invention can be folded thinly during transportation, which is very convenient, and it is also possible to transport a large number of items on a loading platform, which is economical. Of course, when installing it on a window, all the vertical bars can be erected at once by moving the caps or horizontal bars in parallel to return to their original state. is held upright,
When attaching a handrail to a window, it can be installed without bending while correcting the upright state of the vertical bars relative to the window, and when attaching horizontal bars to the window, each vertical bar can be held upright. Otherwise, it will fall to the left and right, putting unbalanced weight on the horizontal bars, and the horizontal bars will tilt while being installed with screws, resulting in the handrail being installed on the window at an angle.However, with this invention, the vertical bars are fixed. Since it is held upright, it can be easily and reliably installed without fear of tipping, and its handling is extremely easy.
