Description

Technical Field

[0001] The utility model relates to the field of bathroom products, in particular to a safety handrail structure. Background Art

[0002] Safety handrails are crossbars or handles installed in toilets or bathrooms to maintain body balance or support the body, which can effectively prevent the elderly and children from falling or slipping on slippery floors. For example, a Chinese patent document discloses a technical solution with a patent application number of 201910323471.9 and the name of "A Foldable Health Bathroom Handrail", which mainly includes an upper fixed rod, a lower fixed rod, a handrail rod, a slider, a sliding shaft and an oblique support, wherein sliding grooves are provided on both sides of the middle of the handrail rod, the upper fixed rod and the lower fixed rod are respectively fixed on the wall, one end of the handrail rod is hinged on the upper fixed rod, one end of the oblique support is hinged on the lower fixed rod, the slider is hinged on the other end of the oblique support, the sliding shaft is arranged on the slider, and the slider is slidably arranged on the sliding groove through the sliding shaft. When in use, the swinging and folding of the handrail rod and the oblique support is realized through the cooperation of the sliding groove and the sliding shaft, so that the entire safety handrail is folded and placed against the wall to reduce space occupancy. However, in actual use, it still has the following shortcomings:

[0003] First, after the safety handrail of this scheme is folded, the slider and the diagonal support protrude outward, and the protrusion is very obvious, making the overall safety handrail shaped like the letter H. Such a protruding structure constitutes a sharp corner that is extremely easy to cause bumps and injuries, posing a major safety hazard, especially when the elderly accidentally slip, which will increase the accidental bumps and injuries to the elderly.

[0004] Second, since the sliding grooves are arranged on both sides of the middle part of the handrail rod, the sliding grooves are completely exposed. When the handrail rod is swung, the user's hands are particularly likely to come into contact with the sliding grooves and the sliding shafts, causing the hands to be pinched and injured. This makes the safety handrail have a large safety problem in use.

[0005] Third, since the sliding grooves are arranged on both sides of the middle part of the handrail rod, dust and dirt are easily accumulated on the sliding grooves, and they need to be cleaned frequently. When cleaning, the handrail rod needs to be swung continuously to prevent the sliding shaft from obstructing the cleaning and wiping, which makes it very inconvenient to clean the safety handrail.

[0006] Therefore, in view of the aforementioned deficiencies of this type of safety handrail, it is very necessary to improve it so as to better meet people's application needs. Utility Model Content

[0025] like Figure 1 , Figure 2As shown, the utility model describes an upward folding safety handrail structure, comprising a base 1, an handrail cross bar 2, a supporting diagonal bar 3, and a sliding bar 4. The lower side wall of the handrail cross bar 2 is provided with a lower avoidance position 21 for accommodating the supporting diagonal bar 3 and the sliding bar 4. The lower side wall of the handrail cross bar 2 is also provided with a slide groove 22 connected to the lower avoidance position 21, and the notch of the slide groove 22 faces the lower avoidance position 21. The rear end of the handrail cross bar 2 and the rear end of the supporting diagonal bar 3 are respectively hinged on the base 1, and the supporting diagonal bar 3 is located below the handrail cross bar 2. The sliding bar 4 is hinged at the front end of the supporting diagonal bar 3, and the sliding bar 4 slides into the slide groove 22 after passing through the lower avoidance position 21. The utility model sets a lower avoidance space 21 and a slide groove 22 on the lower side wall of the handrail crossbar 2. After the whole is folded together, it can not only accommodate the supporting inclined rod 3 and the sliding rod 4, but also can make the safety handrail folded as a whole into a straight rod with fewer protruding parts, greatly reducing the sharp corners after folding, so as to reduce safety hazards. When the elderly accidentally slip, it is not easy to cause bumps, reducing accidental bumps and injuries to the elderly. In addition, the two sides of the handrail crossbar 2 remain smooth and flat, and it is not easy to be pinched when using it, so as to greatly reduce the safety problem of use, and it is not easy to accumulate dust and dirt, and it is also very convenient to clean.

[0026] In order to further improve the comfort of use, such as Figure 1 As shown, the upper side wall of the handrail crossbar 2 is also provided with an anti-icing hand touch portion 5. In this way, when using the handrail crossbar 2 in cold weather, the hand will not be so cold when touching it, so as to improve the comfort of use. In actual application, the anti-icing hand touch portion 5 can be made of plastic material, or made of metal with leather coating, and the metal can be made of stainless steel or iron. The handrail crossbar 2 can be made of stainless steel or iron. Through such a structural design of different materials, not only can the hand be prevented from getting cold, but also a contrasting effect in the color of the material can be formed, so as to play a certain decorative role.

[0027] In order to make the ends of the safety handrails more rounded, more comfortable to hold and reduce the damage caused by bumps, Figure 2 As shown, the front end of the anti-icing hand touching portion 5 is further provided with a round head portion 51 , and the round head portion 51 covers the front end of the handrail cross bar 2 .

[0028] In order to make the overall structure of the safety handrail more compact, such as Figure 2 and Figure 3 As shown, the upper side wall of the handrail crossbar 2 is also provided with an upper avoidance space 23, and the anti-icing hand touch portion 5 is embedded in the upper avoidance space 23. In this way, the protruding portion of the safety handrail as a whole can be reduced, so that the safety handrail as a whole can be folded together to remain folded into a straight rod, thereby reducing the damage caused by bumps.

[0029] In order to make the installation of the anti-icing hand touch part 5 and the upper avoidance position 23 easier, as shown in FIG. Figure 2 and Figure 3 As shown, an insertion protrusion 52 and an insertion groove 231 that are assembled and matched together are also provided between the anti-icing hand touch portion 5 and the upper avoidance position 23. In this way, they can be quickly assembled and connected together, which improves the convenience of assembly. Specifically, the insertion protrusion 52 is set on the anti-icing hand touch portion 5, and the insertion groove 231 is set on the upper avoidance position 23. Of course, the positions of the insertion protrusion 52 and the insertion groove 231 can also be interchanged. In actual application, in order to make the installation of the anti-icing hand touch portion 5 more secure and not easy to loosen, as shown in FIG. Figure 2 and Figure 3 As shown, the utility model also includes a locking screw 6, the slide groove 22 is a groove structure that penetrates to the front end of the handrail cross bar 2, and the round head part 51 is provided with an embedded part 53 embedded in the slide groove 22, and one end of the locking screw 6 passes through the handrail cross bar 2 and is locked on the embedded part 53.

[0030] like Figure 3 As shown, the upper avoidance position 23 is located at the front end of the handrail crossbar 2, and the lower avoidance position 21 is located at the rear end of the handrail crossbar 2, so that the handrail crossbar 2 is formed into a Z-shaped handrail rod structure. In this way, while ensuring that the handrail crossbar 2 has a very good structural strength, the spatial position of the handrail crossbar 2 can be reasonably utilized to accommodate the supporting inclined rod 3, the sliding rod 4 and the anti-icing hand touch part 5, so that after the safety handrail is folded together as a whole, it can still remain folded into a straight rod, which can not only reduce the space occupied after folding, but also reduce the protruding parts and reduce the damage caused by bumps.

[0031] In order to further reduce the protruding part of the safety handrail after it is folded, such as Figure 5 As shown, the rear end of the supporting diagonal rod 3 is also provided with an anti-collision avoidance inclined surface 31. By setting the anti-collision avoidance inclined surface 31, after the safety handrail is folded together as a whole, the lower end surface of the safety handrail can be bent backward to form an avoidance position, and combined with the structural design of the round head 51, the two ends of the safety handrail after the whole is folded together are not too sharp, even if a bump accident occurs, the damage caused by the bump can be greatly reduced, and the use is safer, more secure and reliable.

[0032] like Figure 5 and Figure 6 As shown, the rear end of the supporting diagonal rod 3 is also provided with a bent portion 32 bent toward the base 1, the anti-collision avoidance inclined surface 31 is provided on the bent portion 32, and the lower end of the base 1 is also provided with a clearance area 10 for accommodating the bent portion 32. Through such a structural design, even if the anti-collision avoidance inclined surface 31 is provided, the influence on the structural strength of the supporting diagonal rod 3 is greatly reduced, so as to ensure the support reliability of the supporting diagonal rod 3.

[0033] In order to further improve the structure of the base 1 and make it simple, scientific and reasonable, as Figure 4 As shown, the base 1 includes a base body 11 and a shielding surface cover 12. The base body 11 is provided with an installation through hole 111 that runs from the front to the back. The shielding surface cover 12 is placed on the front of the base body 11, and the shielding surface cover 12 shields the installation through hole 111. The rear end of the handrail cross bar 2 and the rear end of the supporting diagonal bar 3 are respectively hinged on the base body 11. By setting the shielding surface cover 12, the installation through hole 111 on the base body 11 can be shielded and hidden, so that no installation through hole 111 is exposed on the base 1, so that the outer surface of the base 1 is more concise, and the installation through hole 111 is not easy to hide dirt and dirt, and it is more convenient to clean. It can also make the screws in the installation through hole 111 not easily corroded by water vapor, so as to ensure the firmness of the safety handrail installed on the wall. In actual application, the base body 11 can be made of stainless steel or iron. The shielding surface cover 12 can be made of plastic material. Through such structural design of different materials, a contrasting effect in material color can be formed, which plays a certain decorative role.

[0034] In order to make the overall structure of the base 1 more compact, Figure 4 As shown, the front of the base body 11 is provided with a yielding groove 112, and the shielding surface cover 12 is embedded in the yielding groove 112, and the front of the shielding surface cover 12 is flush with the front of the base body 11; the installation through-hole 111 is arranged at the bottom of the yielding groove 112. In this way, while ensuring that the base body 11 has a very good structural strength, the overall structure of the base 1 can be made more compact, so that after the safety handrail is folded together as a whole, it can still be folded into a straight rod, thereby reducing the space occupied after folding. In actual application, the number of the installation through-holes 111 is several, and preferably, the number of the installation through-holes 111 is four. In this way, it can be ensured that the base body 11 can be firmly installed on the wall.

[0035] In actual application, the sliding rod 4 can be positioned by the following methods, so that a stable triangular support structure is formed after the safety handrail is unfolded: First, the slide groove 22 is a non-through groove structure, and the sliding rod 4 presses on the groove bottom of the slide groove 22. Second, the sliding rod 4 is provided with a top-locking convex portion, and the top-locking convex portion presses on the notch of the slide groove 22. Third, the slide groove 22 is a groove structure that penetrates to the front end of the handrail crossbar 2, and the sliding rod 4 presses on the round head 51 or the embedded portion 53 of the anti-icing hand touch portion 5.
