Description

Technical Field

[0001] This utility model relates to the field of shower grab bars, specifically a shower grab bar. Background Technology

[0002] For the elderly, those with physical weakness, or those recovering from surgery, there is a significant risk of falling while showering. Even if they can sit in a chair to shower, it is very difficult for them to sit down and stand up. Therefore, these individuals need shower handrails to maintain their balance and assist them in sitting down and standing up.

[0003] Common shower grab bars are U-shaped fixed rods on the wall, which makes them difficult to adapt to people of different heights and to meet the needs of users who want to stand or sit while showering, greatly limiting the usage scenarios of shower grab bars. Existing products include shower grab bars that can slide up and down, which are usually locked by a combination of latches and teeth. However, the latches are usually located inside the housing, and it is difficult to ensure that the latches are aligned and locked in the slots of the teeth after adjusting the height of the grab bar. If the latches are locked on the protruding part of the teeth, they are easily damaged. When the grab bar is under pressure, there is a risk that the latches may fail and the grab bar may slide down, posing a great safety hazard.

[0004] The research objective of this utility model is to design a shower grab bar that can adapt to different usage scenarios and has high safety, in order to address the problems existing in the above-mentioned prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a shower grab bar that can effectively solve the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A shower grab bar, wherein two shower grab bars are installed symmetrically on both sides during actual use, the shower grab bar comprising:

[0008] The mounting base has a rack portion including several slots on at least one side;

[0009] A sliding seat is provided with a handrail body and is slidably connected to the fixed seat. The sliding seat includes an inner cavity that communicates with the rack portion. A locking member including a contact surface and a locking part is rotatably provided in the mounting cavity. A first elastic member is connected between the inner wall of the mounting cavity and the locking member. The height of the contact surface is higher than the height of the locking member. A driving part extends outward from the outer side of the locking member. When locked, the first elastic member pushes the locking member inward until the locking part locks into the corresponding slot, and the contact surface abuts against the upper wall of the mounting cavity.

[0010] The button slides up and down into the mounting cavity and corresponds to the driving part. The button includes a second elastic element with its upper and lower ends respectively abutting between the bottom side of the driving part and the inner wall of the button. When unlocking, the button is pressed upward to make the second elastic element push the driving part to swing upward, causing the locking element to swing outward to overcome the elastic force of the first elastic element and disengage from the rack part.

[0011] Furthermore, the locking element is larger at the top and smaller at the bottom, with the lower part extending downward and inward at the rear end to form the locking part. The upper part is a connecting part that is rotatably connected to the inner wall of the mounting cavity via an outwardly offset pivot. The inner side of the upper end of the connecting part is set as the abutting surface that abuts against the inner side of the upper wall of the mounting cavity when locked. The lower wall of the mounting cavity is inclined to form a limiting surface with an inclination angle corresponding to the inclination angle of the lower part of the locking element. A limiting groove is recessed on the limiting surface. The first elastic element includes an upper top piece and a lower top piece that are distributed vertically and respectively abut against the lower outer wall of the locking element and the limiting surface, as well as a connecting part that is arc-shaped and transitions between the upper top piece and the lower top piece with an inward opening. The end of the lower top piece is folded downward and limitedly inserted into the limiting groove.

[0012] Furthermore, a reinforcing plate located inside the connecting portion is connected between the upper and lower top plates. The reinforcing plate is designed as an arc with the opening facing inward. The included angle A1 between the upper and lower top plates is 20°-30°. The thickness of the first elastic element is 2mm-4mm, and the force value N1 of the first elastic element is greater than 5N.

[0013] Furthermore, the radius of the reinforcing piece is larger than the radius of the connecting portion.

[0014] Furthermore, the second elastic element is sheet-shaped and includes a pushing part that is limited at one end to the outside of the locking element and laterally located below the driving part, and a squeezing part that is connected to the pushing part at one end. The bottom of the button has a plurality of limiting ribs, and the two sides of the inner wall have limiting protrusions with a spacing adapted to the width of the squeezing part. The other end of the squeezing part is limited between the two limiting protrusions and first folds upward and arches to a height higher than the driving part, then folds downward and extends to a height lower than the driving part, and finally the lower end is tilted outward to form a snap-fit ​​part that is engaged between the plurality of limiting ribs. The included angle A2 between the pushing part and one end of the squeezing part is 75°-85°, and the angle A3 of the lower end of the squeezing part tilting outward is 150°-160°. The thickness of the second elastic element is 4mm-6mm, and the force N2 of the second elastic element is 65N-75N.

[0015] Furthermore, the fixed base has sliding ends on both sides located in front of the rack portion. The sliding base is located in front of the fixed base and is folded backward on both sides and then folded towards each other to form a sliding portion. Anti-slip members are embedded on the opposing sides of the two sliding portions, and the opposing sides of the two anti-slip members are recessed to form a sliding groove that slides up and down on the outside of the two sliding ends. The rear part of the sliding portion is recessed and has an installation groove. A protective shell is covered on the outside of the installation groove. The inner cavity of the protective shell and the installation groove enclose each other to form the installation cavity.

[0016] Furthermore, the upper and lower ends of the two sliding grooves are respectively provided with a plurality of anti-slip protrusions that abut against the outer wall of the two sliding ends.

[0017] Furthermore, the lower outer side of the protective shell is recessed and open to form a mounting port. The inner side of the mounting port is recessed and has a guide groove extending vertically. The upper end of the button is inserted into the mounting port. The inner opening of the button corresponds to the mounting port and extends inward on both the front and rear sides, then folds in opposite directions to form a guide portion hooked into the guide groove. The lower middle part of the mounting port has a resetting portion protruding and a positioning groove recessed on both the front and rear sides. The bottom of the two guide portions corresponds vertically to the two positioning grooves, and the opposing sides have a positioning portion corresponding to the resetting portion protruding. The pushing portion is limited between the two guide portions.

[0018] Furthermore, the upper and lower outer walls of the fixed base are respectively detachably provided with upper limit protrusions and lower limit protrusions corresponding to the upper and lower limits of the sliding base.

[0019] Furthermore, the handrail body includes a handrail bar extending forward and backward on the front side of the sliding seat and rotatably connected to the sliding seat at its rear end, and a support rod with one end connected to the bottom of the handrail bar and the other end extending downward and backward at an angle to abut against the front side of the sliding seat.

[0020] Therefore, the beneficial effects of this utility model are:

[0021] 1. By adding the first and second elastic elements, the height of the handrail can be adjusted after the locking mechanism is unlocked by pressing a button, accommodating users of different heights and different usage methods such as standing or sitting while showering, thus improving the overall adaptability of the shower handrail. Furthermore, during the up-and-down sliding adjustment, when the locking part of the locking mechanism aligns with the teeth of the rack and pinion rather than the slot, the second elastic element causes the button to slide down and reset after the user releases the button. The locking mechanism, supported by the inward movement of the first elastic element, keeps the locking part pressed against the outer wall of the teeth. After the user presses down on the handrail body and causes the sliding seat to slide down, the locking component is pushed inward again by the first elastic element and locks into the slot on the lower side of the tooth, and the contact surface abuts against the upper wall of the mounting cavity to achieve locking. Therefore, through the elastic clearance of the first elastic element, the locking part of the locking component will not be squeezed and damaged when it is not aligned with the slot. Moreover, the locking component can be locked by pressing down on the handrail body again, avoiding the risk of the handrail body sliding down due to the locking component jamming and damage. In addition, this simple adjustment method that can be adjusted at will can meet the simple operation needs of elderly users.

[0022] 2. By setting the locking part and limiting surface with corresponding tilt angles, both sides of the first elastic element can be stably abutted on the outer wall of the locking part and the limiting surface respectively, which improves the stability of the elastic force of the first elastic element on the locking element and ensures that the direction of the elastic force of the first elastic element on the locking element is always inward, thus improving the stability of the direction of the elastic force of the first elastic element on the locking element. At the same time, the limiting groove limits the end of the lower top piece, improving the overall stability of the first elastic element when it deforms and preventing it from excessive displacement.

[0023] 3. By adding limiting protrusions and limiting ribs, the installation of the second elastic element only requires inserting it into the button and setting the outer side of the extrusion part between the two limiting protrusions, and the snap-fit ​​part between several limiting ribs. The limiting setting of the limiting protrusions and limiting ribs can ensure the stability of the second elastic element after installation, which greatly improves the ease of installation of the second elastic element.

[0024] 4. By setting the included angle A2, the push part and the squeeze part are set at an acute angle. When the button is pressed upward to push and squeeze the squeeze part, the push part can stably push the drive part upward, preventing the drive part from completely disengaging from the push part. This improves the stability of the second elastic element's elastic force acting on the drive part. Furthermore, the upper arch of the squeeze part is positioned between the drive part and the button, which can assist the first elastic element in restricting the outward swing of the locking element. This prevents the locking from failing when the slide moves upward, further improving the stability of the locking.

[0025] 5. By adding a sliding end located on the front side of the rack, when the handrail body is subjected to force and the sliding seat has an upward tilting tendency, the force is transmitted sequentially to the sliding seat, sliding part, anti-slip component, and sliding end. The upper rear side of the anti-slip component's groove rubs against the rear side of the sliding end and the lower front side rubs against the front side of the sliding end, thereby reducing the pressure on the locking part, reducing the relative displacement tendency between the rack and the locking component, and extending the service life of the locking component.

[0026] 6. By cooperating with the guide groove and guide part, the stability of the button's up and down sliding is improved. With the addition of the reset part and positioning groove, after the button is released from the pressure, it can automatically slide down and reset to the position where the two positioning parts abut against the top of the reset part and the two guide parts are inserted into the two positioning grooves. This greatly improves the stability and accuracy of pressing the button up and the button's automatic reset when sliding down. Furthermore, by limiting the push part between the two guide parts, one end of the second elastic element can be limited. Combined with the setting of the limiting boss and the limiting ridge, the button can limit the entire second elastic element, thereby avoiding excessive displacement after the second elastic element deforms and improving the working stability of the second elastic element.

[0027] 7. By adding a reinforcing plate, when the top is under pressure, the reinforcing plate can assist in supporting the pressure on the connecting part, reducing the pressure borne by the connecting part. This reduces the probability of the first elastic element fracturing due to metal fatigue under prolonged or repeated pressure, thus improving the structural strength of the first elastic element and extending its service life. Furthermore, by increasing the radius of the reinforcing plate, its force value under pressure is greater than that of the connecting part. When the top is under pressure, the reinforcing plate can act as the main support for bearing the pressure, while the connecting part acts as an auxiliary support, further reducing the pressure borne by the connecting part.

[0036] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0037] Example 1

[0038] refer to Figure 1-7 A shower grab bar, comprising:

[0039] The fixing base 1 has a rack portion 11 including a plurality of slots 111 on at least one side;

[0040] The sliding seat 2 is provided with a handrail body 3 and is slidably connected to the fixed seat 1. The sliding seat 2 includes an installation cavity with its inner side communicating with the rack part 11. A locking member 4, including an abutment surface 41 and a locking part 42, is rotatably provided in the installation cavity. A first elastic member 5 is connected between the inner wall of the installation cavity and the locking member 4. The height of the abutment surface 41 is higher than the height of the locking member 4. A driving part 43 extends outward from the outer side of the locking member 4. When locked, the first elastic member 5 pushes the locking member 4 inward until the locking part 42 locks into the corresponding slot 111. The abutment surface 41 abuts against the upper wall of the installation cavity. When the sliding seat 2 of the handrail body 3 is pressed down, the slot lifts the locking part 42, causing the locking member 4 to swing inward and lock between the slot 111 and the upper wall of the installation cavity, thus restricting the relative displacement between the sliding seat 2 and the fixed seat 1.

[0041] Button 6 slides up and down into the mounting cavity and corresponds to the driving part 43. Button 6 includes a second elastic element 7 with its upper and lower ends respectively abutting between the bottom side of the driving part 43 and the inner wall of the button 6. When unlocking, pressing button 6 upward causes the second elastic element 7 to push the driving part 43 upward, causing the locking element 4 to swing outward, overcoming the elastic force of the first elastic element 5 and disengaging from the rack part 11. Specifically, both the first elastic element 5 and the second elastic element 7 can be made of springs.

[0042] The above-described structure, through the addition of the first elastic element 5 and the second elastic element 7, allows the handrail body 3 to be height-adjusted after the locking element 4 is unlocked by pressing the button 6, accommodating users of different heights and different usage methods such as standing or sitting while showering, thus improving the overall adaptability of the shower handrail. Furthermore, during the up-and-down sliding adjustment, when the locking part 42 of the locking element 4 is aligned with the teeth of the rack part 11 rather than within the slot 111, after the user releases the button 6, the second elastic element 7 causes the button 6 to slide down and reset. The locking element 4, under the inward pushing and swinging of the first elastic element 5, keeps the locking part 42 pressed tightly against the teeth. In the wall state, after the user presses down on the handrail body 3 and causes the sliding seat 2 to slide down, the locking member 4 is pushed inward again by the first elastic member 5 and locked into the slot 111 on the lower side of the tooth, and the contact surface 41 abuts against the upper wall of the mounting cavity to achieve locking. Therefore, through the elastic relief of the first elastic member 5, the locking part 42 of the locking member 4 will not be squeezed and damaged when it is not aligned with the slot 111. Moreover, the locking member 4 can be locked by pressing down on the handrail body 3 again, avoiding the risk of the handrail body 3 sliding down due to the locking member 4 getting stuck and damaged. In addition, this simple adjustment method that can be adjusted at will can meet the simple operation needs of elderly users.

[0043] To improve the stability of the elasticity of the first elastic element 5 in the action of the locking element 4, the locking element 4 is larger at the top and smaller at the bottom, with the lower part extending downward and inward to form the locking part 42. The upper part is a connecting part 44 that is rotatably connected to the inner wall of the mounting cavity via an outwardly offset pivot 441. The inner side of the upper end of the connecting part 44 is set as the abutting surface 41 that abuts against the inner side of the upper wall of the mounting cavity when locked. The lower wall of the mounting cavity is inclined to form a limiting surface 231 with an inclination angle corresponding to the inclination angle of the lower part of the locking element 4. A limiting groove 232 is recessed on the limiting surface 231. The first elastic element 5 includes an upper top piece 51 and a lower top piece 52 that are distributed vertically and respectively abut against the lower outer wall of the locking element 4 and the limiting surface 231, and a connecting part 53 that is arc-shaped and connects the upper top piece 51 and the lower top piece 52 with an inward opening. The end of the lower top piece 52 is folded downward and inserted into the limiting groove 232 for limitation. By setting the locking part 42 and the limiting surface 231 with corresponding tilt angles, both sides of the first elastic member 5 can be stably abutted on the outer wall of the locking part 42 and the limiting surface 231 respectively, which improves the stability of the elastic force of the first elastic member 5 on the locking member 4, and ensures that the elastic force of the first elastic member 5 on the locking member 4 is always inward, thus improving the stability of the direction of the elastic force of the first elastic member 5 on the locking member 4. At the same time, the limiting groove 232 limits the end of the lower top piece 52, improving the overall stability of the first elastic member 5 when it deforms and preventing it from excessive displacement.

[0044] To ensure that the elastic force of the first elastic element 5 is sufficient to drive the locking element 4 to lock inward, specifically, the included angle A1 between the upper top piece 51 and the lower top piece 52 is 20°-30°, the thickness of the first elastic element 5 is 2mm-4mm, the force value N1 of the first elastic element 5 is >5N, preferably, the included angle A1 is 26.3°, and the thickness of the first elastic element 5 is 3mm.

[0045] To improve the ease of installation of the second elastic element 7, the second elastic element 7 is designed as a sheet. The second elastic element 7 includes a pushing part 71 with one end limited and abutting against the outside of the locking element 4 and laterally located below the driving part 43, and a squeezing part 72 with one end connected to the pushing part 71. The bottom of the button 6 has a plurality of limiting ribs 61 protruding, and the two sides of the inner wall have limiting protrusions 62 with a spacing adapted to the width of the squeezing part 72. The other end of the squeezing part 72 is limited between the two limiting protrusions 62 and first folds upward and arches to a height higher than the driving part 43, then folds downward and extends to a height lower than the driving part 43, and finally the lower end tilts and folds outward to form a snap-fit ​​part 73 that is snapped between the plurality of limiting ribs 61. Thus, by adding the limiting protrusions 62 and the limiting ribs 61, the installation of the second elastic element 7 only requires inserting it into the button 6 and limiting the outer side of the pressing part 72 between the two limiting protrusions 62, and the snap-fit ​​part 73 is spaced between several limiting ribs 61. The limiting setting of the limiting protrusions 62 and the limiting ribs 61 can ensure the stability of the second elastic element 7 after installation, which greatly improves the ease of installation of the second elastic element 7.

[0046] To ensure the stability of the elastic force of the second elastic element 7 acting on the driving part 43, specifically, the included angle A2 between the pushing part 71 and one end of the squeezing part 72 is 75°-85°, the angle A3 of the lower end of the squeezing part 72 tilting outward is 150°-160°, the thickness of the second elastic element 7 is 4mm-6mm, and the force value N2 of the second elastic element 7 is 65N-75N. Preferably, the included angle A2 is 80°, the angle A3 of the lower end of the squeezing part 72 tilting outward is 155°, the thickness of the second elastic element 7 is 5mm, and the force value N2 of the second elastic element 7 is 70N. By setting the included angle A2, the pushing part 71 and the squeezing part 72 are set at an acute angle. When the button 6 is pressed upward to squeeze the squeezing part 72, the pushing part 71 can stably push the driving part 43 upward, preventing the driving part 43 from completely disengaging from the pushing part 71. This improves the stability of the second elastic member 7's elastic force acting on the driving part 43. Furthermore, the upper arch of the squeezing part 72 is positioned between the driving part 43 and the button 6, which can assist the first elastic member 5 in restricting the outward swing of the locking member 4. This prevents the locking from failing when the slide moves upward, further improving the stability of the locking.

[0047] To reduce the pressure transmitted to the locking element 4 when the handrail body 3 is subjected to force, the fixed base 1 has sliding ends 12 on both sides located in front of the rack part 11. The sliding base 2 is located in front of the fixed base 1 and is folded backward on both sides and then folded towards each other to form a sliding part 21. Anti-slip parts 22 are embedded on the opposing sides of the two sliding parts 21, and the opposing sides of the two anti-slip parts 22 are recessed to form a sliding groove 221 that slides up and down on the outside of the two sliding ends 12. The rear part of the sliding part 21 is recessed to provide a mounting groove 23. A protective shell 24 is provided on the outside of the mounting groove 23. The inner cavity of the protective shell 24 and the mounting groove 23 enclose each other to form the mounting cavity. By adding a sliding end 12 located in front of the rack portion 11, when the handrail body 3 is subjected to force and the sliding seat 2 has an upward tilting tendency, the force is sequentially transmitted to the sliding seat 2, the sliding portion 21, the anti-slip member 22, and the sliding end 12. The upper rear side of the groove 221 of the anti-slip member 22 rubs against the rear side of the sliding end 12, and the lower front side rubs against the front side of the sliding end 12, thereby reducing the pressure on the locking portion 42, reducing the relative displacement tendency between the rack portion 11 and the locking member 4, and extending the service life of the locking member 4.

[0048] In order to improve the frictional contact between the upper and lower ends of the anti-slip component 22 and the sliding end 12, a number of anti-slip protrusions 222 are provided on the upper and lower ends of the two sliding grooves 221 respectively, which abut against the outer wall of the two sliding ends 12.

[0049] To improve the stability of button 6 after installation, the lower outer part of the protective shell 24 is recessed and opened to form a mounting port 241. The inner side of the mounting port 241 is recessed and has a guide groove 242 extending vertically. The upper end of button 6 is inserted into the mounting port 241. The inner opening of button 6 corresponds to the mounting port 241 and extends inward on both the front and rear sides and then folds in opposite directions to form a guide part 63 that hooks into the guide groove 242. The lower middle part of the mounting port 241 has a protruding reset part 243 and a recessed positioning groove 244 on both the front and rear sides. The bottom of the two guide parts 63 corresponds to the two positioning grooves 244 vertically, and the opposing sides have protruding positioning parts 64 corresponding to the reset part 243. The pushing part 71 is limited between the two guide parts 63. The cooperation between the guide groove 242 and the guide part 63 improves the stability of the button 6 sliding up and down. With the addition of the reset part 243 and the positioning groove 244, after the button 6 is released from the pressure, the button 6 can automatically slide down and reset to the position where the two positioning parts 64 abut against the top of the reset part 243 and the two guide parts 63 are inserted into the two positioning grooves 244. This greatly improves the stability and accuracy of pressing the button 6 up and the automatic reset of the button 6 sliding down. Furthermore, by limiting the push part 71 between the two guide parts 63, one end of the second elastic member 7 can be limited. With the combination of the limiting boss and the limiting ridge 61, the button 6 can limit the second elastic member 7 as a whole, thereby avoiding excessive displacement after the second elastic member 7 is deformed and improving the working stability of the second elastic member 7.

[0050] In order to improve the stability of the sliding seat 2 sliding up and down and prevent it from detaching from the fixed seat 1, the upper outer wall and the lower outer wall of the fixed seat 1 are respectively provided with upper limit protrusion 13 and lower limit protrusion 14 corresponding to the upper and lower sides of the sliding seat 2.

[0051] Specifically, the handrail body 3 includes a handrail rod 31 extending forward and backward on the front side of the sliding seat 2 and rotatably connected to the sliding seat 2 at its rear end, and a support rod 32 with one end connected to the bottom of the handrail rod 31 and the other end extending downward and backward at an angle to abut against the front side of the sliding seat 2.

[0052] Example 2

[0053] refer to Figure 8 The difference between this embodiment and Embodiment 1 is that:

[0054] To improve the structural strength of the first elastic element 5, a reinforcing plate 54 located inside the connecting portion 53 is connected between the upper top plate 51 and the lower top plate 52. The reinforcing plate 54 is designed as an arc with its opening facing inward. Thus, by adding the reinforcing plate 54, when the upper top is under pressure, the reinforcing plate 54 can assist in supporting the pressure on the connecting portion 53, reducing the pressure borne by the connecting portion 53. This reduces the probability of the connecting portion 53 fracturing due to metal fatigue under prolonged or repeated pressure, thereby improving the structural strength of the first elastic element 5 and extending its service life.

[0055] To further enhance the supporting force of the reinforcing plate 54, the reinforcing plate 54 is designed as an arc with its opening facing inward and a radius larger than that of the connecting part 53. By increasing the radius of the reinforcing plate 54, its force value under pressure is greater than that of the connecting part 53. When the top is under pressure, the reinforcing plate 54 can act as the main support bearing the pressure, and the connecting part 53 can act as the auxiliary support bearing the pressure. This further reduces the pressure borne by the connecting part 53, thereby further reducing the probability of the connecting part 53 breaking due to metal fatigue under prolonged or repeated pressure on the first elastic member 5. This improves the structural strength of the first elastic member 5 and extends its service life.

[0056] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.

[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
