Description

Technical Field

[0001] The utility model belongs to the technical field of building facilities, in particular to a telescopic safety grab bar. Background Art

[0002] As my country's aging population becomes increasingly prominent, the need for elderly-friendly renovations in existing buildings is increasing. Due to declining physical function, elderly individuals often rely on assistive devices like grab bars in their daily lives. In the design of elderly-friendly renovations for existing buildings, bathroom toilets should be barrier-free, with grab bars installed on both sides. Their location and dimensions must comply with barrier-free design standards.

[0003] Bathrooms in existing buildings are often very small. During the design process for aging-friendly bathroom renovations, it's common to encounter situations where the limited space makes it impossible to install grab bars on either side of the toilet. However, grab bars are crucial for assisting the elderly with self-discipline. Therefore, a retractable grab bar could be widely used in aging-friendly bathroom renovations in existing buildings, effectively improving the quality of life for the elderly, providing convenience for their daily lives, and boosting their confidence and mental well-being. Utility Model Content

[0004] The purpose of the utility model is to provide a retractable safety grab bar to solve the problem raised in the above background art that a safety grab bar of a suitable size cannot be provided in the bathroom during the renovation design of an existing building.

[0005] The technical solution adopted is:

[0006] A retractable safety grab bar comprises two fixed grab bars, a locking device and a sliding grab bar.

[0007] The two fixed grab bars are arranged in parallel, and the sliding grab bar is U-shaped.

[0008] One side of the sliding grab bar is plugged into one side of the fixed grab bar.

[0009] The other side of the sliding grab bar is plugged into one side of another fixed grab bar.

[0010] A locking device is provided between the sliding grab bar and the fixed grab bar.

[0011] The sliding grab bar can be inserted into the fixed grab bar.

[0012] The locking device may include a locking housing, a spring, a pressure rod, an upper clamping plate, a lower clamping plate and a pressure cap.

[0013] The bottom of the locking housing is fixed to the inner surface of the sliding grab bar.

[0014] The two ends of the spring respectively abut against the lower clamping plate fixed at the bottom of the pressure rod and the inner bottom surface of the locking shell.

[0015] An upper clamping plate is fixed on the middle upper part of the pressure rod, and the upper clamping plate is located in the locking shell.

[0016] A pressure cap is fixed on the top of the pressure rod and passes through the top of the locking shell, and the position corresponds to the multiple limiting holes.

[0017] A plurality of limiting holes are provided on the fixed grab bar.

[0018] The two fixed grab bars are arranged up and down, and the locking device is arranged between the fixed grab bar and the sliding grab bar located at the lower part.

[0019] Its advantages are:

[0020] Retractable safety grab bars can be installed inside smaller bathrooms to meet the needs of elderly-friendly renovations of bathroom toilets.

[0021] The horizontal movement distance of the sliding grab bar can be adjusted by changing the position of the limit hole of the fixed grab bar to adapt to the different needs of various spaces. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] A telescopic safety grab bar comprises two fixed grab bars 1, a locking device 4 and a sliding grab bar 2.

[0031] The two fixed grab bars 2 are both arranged horizontally and in parallel, and are mainly used for installing the sliding grab bar 2 and providing a stable sliding space for the sliding grab bar 2.

[0032] The sliding grab bar 2 is U-shaped and is mainly used to adjust the horizontal width of the safety grab bar.

[0033] One side of the sliding grab bar 2 is plugged into one side of the fixed grab bar 1 located at the top.

[0034] The other side of the sliding grab bar 2 is plugged into one side of the fixed grab bar 1 located at the bottom.

[0035] A locking device 4 is provided between the sliding grab bar 2 and the fixed grab bar 1 .

[0036] Furthermore, the sliding grab bar 2 is inserted into the fixed grab bar 1 .

[0037] The fixed grab bar 1 has a first concave groove 11, and the sliding grab bar 2 has a second concave groove 12 on both sides, corresponding to the guide limit. The two grooves have the same size and shape, and the shape of the groove is non-circular, which can prevent the sliding grab bar 2 from shaking irregularly. The overall external shape of the fixed grab bar 1 is circular.

[0038] Furthermore, the locking device 4 includes a locking housing 3 , a spring 9 , a pressure rod 10 , an upper clamping plate 8 , a lower clamping plate 7 and a pressure cap 6 .

[0039] The bottom of the cylindrical locking housing 3 is fixed to the inner surface of the sliding grab bar 2 .

[0040] The two ends of the spring 9 respectively abut against the lower clamping plate 7 fixed at the bottom of the pressure rod 10 and the inner bottom surface of the locking shell 3.

[0041] An upper clamping plate 8 is fixed to the upper middle portion of the pressure rod 10 , and the upper clamping plate 8 is located inside the locking housing 3 .

[0042] The top of the pressure rod 10 passes through the central hole above the locking shell 3, and the pressure cap 6 is fixed on the top of the pressure rod 10.

[0043] The top of the pressure rod 10 and the pressure cap 6 pass through the sliding grab bar 2 , and the positions correspond to the multiple limiting holes 5 .

[0044] A plurality of limiting holes 5 are provided on the fixed grab bar 1. In this embodiment, there are three of them.

[0045] The bottom of the locking housing 3 is fixed on the second groove 10 .

[0046] Furthermore, the locking device 4 described in this embodiment is provided between the fixed grab bar 1 and the sliding grab bar 2 located at the lower portion.

[0047] The locking device 4 is mainly used to lock or unlock the position of the sliding grab bar 2; the limiting hole 5 is provided on the fixed grab bar 1, and is mainly used to cooperate with the locking device 4 to adjust the position of the sliding grab bar 2.

[0048] The size of the limiting hole 5 is the same as the size of the protruding pressing cap 6 of the locking device 4 .

[0049] Three limiting holes 5 are provided on the fixed grab bar 2 for adjusting the horizontal position of the sliding grab bar 2 to meet the requirements of different usage scenarios.

[0050] Its working principle is:

[0051] A fixed grab bar 1 has multiple mounting edges and can be fixed to the upper wall by bolts.

[0052] Another fixed grab bar 1 has multiple mounting edges and can be fixed to the lower part of the wall by bolts.

[0053] Press the pressure cap 6 of the locking device 4, the pressure cap 6, the pressure rod 10, the upper clamping plate 8 and the lower clamping plate 7 extend into the locking shell 3, the pressure cap 6 disengages from the limit hole 5 (the locking device 4 is in a compressed state), and the sliding grab bar 2 can move relative to the fixed grab bar 1. When it moves to the required length, the spring 9 pushes the lower clamping plate 7, the pressure rod 10, the upper clamping plate 8 and the pressure cap 6 outward. Without external pressure, it rebounds and resets. The pressure cap 6 extends to the limit hole 5 at the set position and is stuck, completing the adjustment of the horizontal position of the sliding grab bar 2.

[0054] When the sliding grab bar 2 is in the retracted state, the entire safety grab bar occupies the smallest space, which may not meet the size and position requirements of the safety grab bar.

[0055] When the locking device 4 is compressed and the sliding grab bar 2 is in an adjustable state, the horizontal position of the sliding grab bar 2 can be quickly adjusted; when the sliding grab bar 2 is in a stretched state, the entire safety grab bar occupies the largest space, meeting the size and position requirements of the safety grab bar.

[0056] The locking device 4 is mounted on the inside of the sliding grab bar 2. Normally, the pressure cap 6 protrudes from the sliding grab bar 2 and locks with the stop hole 5. Pressing the locking device retracts the pressure cap 6 into the sliding grab bar 2, allowing the sliding grab bar 2 to be adjusted in position. When no external pressure is applied, the locking device 4 springs back to its original position. The adjustable length of this grab bar reduces the space occupied by barrier-free grab bars, solving the problem of space constraints in existing building renovation projects that prevent the installation of safety grab bars.
