The present invention relates to a bed rail, in particular to a bed rail used to make it easier for users to get out of bed.

In addition to providing rest for patients, ordinary medical beds also have different functions in response to various needs, such as bedside lifting devices that can make patients more comfortable, bed rails that protect patients from falling off the bed, and so on. The current conventional hospital bed usually includes two bed rails respectively arranged on both sides of the hospital bed. The bed rails can be rotated and controlled in a specific direction, and then located in an upright enclosure state or a lowered non-enclosure state , So that the patient can lie on the bed more safely.

At present, there is an improvement of the bed rail of a hospital bed. A pivoting device is added to the bed rail on one side, so that the bed rail can pivot outward along a pivot center, thereby creating a gap. The user does not need to use the bed rail. From the enclosed state to the non-enclosed state, the feet can be extended out of the hospital bed to sit up or leave the hospital bed. For example, Taiwan Patent No. D119807.

However, when the user wants to sit up, the user’s hand will hold the pivoting device and exert a supporting force on the pivoting device, but because the pivoting device is only connected to the bed rail by a single support point , And it is erected in a suspended manner, and the action of the user pressing down on the pivoting device will easily damage the pivoting device and the bed rail. This design method has room for improvement.

Therefore, the purpose of the present invention is to provide a bed rail that can overcome the disadvantages of the prior art.

The telescopic rod 221 in this embodiment is a multi-section telescopic design. The quick-release members 222 can be pulled to movably tighten the telescopic rod 221 to control whether the telescopic rod 221 can be telescoped or not, and fix the telescopic rod 221 to its length after telescopic.

Referring to FIGS. 1, 2, and 3, the recesses 3 are movably connected to the bed body 6 and are respectively provided for the bottoms of the telescopic rods 221 to abut. Each recess 3 defines an accommodating space that opens upward and is used for extending the bottom of the corresponding telescopic rod 221 (FIG. 2 ). Each screw ring 4 is axially movable and screw-locked to the cross bar 231 of the respective first joint group 23 and is used to limit the position of the quick release sleeve 232. Each non-slip member 5 is sleeved on the grip section 242 of the respective second joint group 24, and is a rubber sleeve made of rubber material.

Referring to Figures 1, 2, and 6, when the present invention is used, the bed rail can be erected relative to the bed body 6 in an enclosed state (Figures 1, 2) and a non-enclosed state in which the height is reduced (Figure 6) Convert between. When the bed rail is in the enclosed state, each support unit 2 can switch between a closed position (FIG. 1) and an open position (FIG. 2) relative to the respective guardrail unit 1.

When the support units 2 are respectively located in the closed position, the extension direction of the link mechanisms 21 is parallel to the length direction of the bed 6, and the bottoms of the telescopic rods 221 of the telescopic mechanisms 22 abut against the recesses. Seat 3.

To switch the support units 2 to the open position, first pull the quick-release members 222 of the telescopic mechanism 22 to release the tight relationship between the quick-release members 222 and the telescopic rods 221 , So that the telescopic rods 221 can perform telescopic functions, and the telescopic rods 221 are slightly retracted upward to a length that can be separated from the recesses 3, and then the linkage mechanisms 21 and together with the telescopic mechanisms are pushed 22 respectively pivot around the vertical axes L and M toward the outside of the bed body 6.

At this time, each support unit 2 is in the open position, the length of the telescopic rod 221 of the telescopic mechanism 22 is extended and the bottom is supported on the ground, and finally the quick-release parts 223 are pulled back to their original positions to tighten the telescoping The rod 221 fixes the telescopic rod 221 to the extended length. The user can sit on the periphery of the bed body 6, and can support the supporting units 2 to sit or stand up. At this time, the user will exert downward pressure on the supporting units 2, but the floor assists in providing The supporting force can reduce the force that each supporting unit 2 bears, so the element of the present invention is less prone to damage and has a longer service life.

Referring to Figures 2, 3, and 4, it is worth mentioning that when each support unit 2 is in the open position, the second joint set 24 of the linkage mechanism 21 and the connected telescopic mechanism 22 can be separated from the The first joint group 23 is used as a crutch.

Specifically, when the second joint set 24 of each supporting unit 2 is connected to the first joint set 23 (as shown in FIG. 3), the insertion section 241 of the second joint set 24 is inserted into the first joint In the insertion valve 235 of the group 23, and the engaging members 233 of the first joint group 23 penetrate the hole 230 of the cross bar 231 and are engaged with the positioning ring groove 244 of the insertion section 241. In addition, the threaded ring 4 abuts against the quick-release sleeve 234, which can prevent the quick-release sleeve 234 from being pushed in the direction of the threaded ring 4 accidentally. The quick release sleeve 232 of the first joint set 23 is located outside the engaging parts 233, so that the engaging parts 233 can be more firmly fixed to the positioning ring groove 244, so that the first joint set 23 and The second joint group 24 is in a combined state.

When the user wants to separate each first joint set 23 and each second joint set 24, the screw ring 4 needs to be screwed in a direction away from the second joint set 24 to the position shown by the imaginary line in FIG. 3 Then, force is applied to push the quick release sleeve 232 of the first joint group 23 toward the screw ring 4, and the return spring 236 of the first joint group 23 provides the insertion valve 235 toward the second The elastic restoring force in the direction of the second joint group 24 causes the insertion valve 235 to move in the direction of the second joint group 24, and at the same time it also applies a force to pull the second joint group 24 away from the first joint group 23, Finally, the outer peripheral surface of the plug valve 235 stops inside the hole 230 of the cross bar 231, so the engaging members 233 of the first joint set 23 move outward in the radial direction from the position of FIG. 3 and protrude In the hole 230, the engaging members 233 are separated from the positioning ring groove 244 of the insertion section 241, and the insertion section 241 of the second joint set 24 can be separated from the insertion valve of the first joint set 23 235.

At this time, the first joint set 23 and the second joint set 24 are in a separated state (as shown in FIG. 4), that is, the second joint set 24 and the telescopic mechanism 22 have been removed from the first joint set 23, And it can be used as a crutch, and the user can move with the crutch formed by the second joint set 24 and the telescopic mechanism 22. It is added that after the first joint set 23 and the second joint set 24 are separated, the user releases the external force applied to the quick release sleeve 232, and the quick release sleeve 232 will be provided by the quick release spring 234. The elastic restoring force pushes and moves toward the second joint group 24 and clamps against the engaging members 233.

To combine the second joint set 24 of each supporting unit 2 with the first joint set 23, the insertion section 241 of the second joint set 24 must be inserted into the first joint set 23 Insert the valve 235. Since the second joint group 24 pushes the insertion valve 235 to move in the direction of the guardrail unit 1, the outer peripheral surface of the insertion valve 235 is no longer blocked by the inside of the hole 230 of the cross bar 231, so that the engagement The member 233 moves inward in the radial direction from the position in FIG. 4 to be engaged with the positioning ring groove 244 again. The first joint group 23 and the second joint group 24 are again in a combined state as shown in FIGS. 2 and 3.

Refer to Figures 1, 2, and 3, and then pull the quick-release parts 222 of the telescopic mechanism 22 to release the tight relationship between the quick-release parts 222 and the telescopic rod 221, and make the telescopic rod 221 retract upward Up to the length that can fit into the recess 3. Then push the link mechanisms 21 to pivot around the vertical axes L and M toward the inner side of the bed body 6 to be parallel to the length of the bed body 6 (Figure 1), and set the telescopic rods 221 slightly Extend downward until the bottom of the telescopic rods 221 can abut against the lengths of the recesses 3, the quick-release parts 223 return to their original positions to tighten the telescopic rods 221, so that the The length is fixed. At this time, the supporting units 2 return to the closed position in FIG. 1.

Finally, each threaded ring 4 is screwed from the position of the imaginary line in FIG. 3 toward the respective second joint group 24 and abuts the respective quick release sleeves 234 to prevent the user from accidentally touching the quick releases. The sleeve 232 causes each quick release sleeve 232 to move in the direction of the respective screw ring 4, thereby accidentally releasing the fixed relationship between the first joint group 23 and the second joint group 24. Therefore, the screw connections The design of ring 4 can achieve safety protection.

Referring to FIGS. 1, 5, 6, and 7, it should be noted that when the bed rail is in the enclosed state, each sleeve 223 is screw-locked to the connecting section 243 of the corresponding second joint set 24 and the telescopic Around the rod 221 and restrict the telescopic rod 221 from pivoting relative to the connecting section 243; when the second joint set 24 and the telescopic mechanism 22 are used as a crutch, the sleeve 223 is also screw-locked to the connecting section 243 and the telescopic section 243 There is a safety protection mechanism around the rod 221. When the bed rail needs to be lowered from the enclosed state to the non-enclosed state, the sleeve 223 of the telescopic mechanism 22 needs to be screwed down to the periphery of the telescopic rod 221 without being screwed around the connecting section 243 The telescopic rod 221 can pivot downward relative to the connecting section 243 to the non-enclosed state, and the recess 3 is driven by the telescopic rod 221 to pivot from the position in FIG. 1 to the position in FIG. 6.

In addition, Figure 1 shows that the bed rail of the present invention is installed on one of the left and right sides of the bed 6, but in actual implementation, it can also be installed on the left and right sides of the bed 6. A bed rail according to the invention. In addition, the bed rail of the present invention can also only be equipped with a guardrail unit 1, a supporting unit 2, a recess 3, a screw ring 4, and a non-slip member 5, which is not limited to the number of this embodiment.

In summary, by the extension of the length of the telescopic mechanism 22 of the support unit 2 and the bottom support on the ground, the support unit 2 as a whole is stably supported, except that the ground can be used to support the support In addition to the weight of the unit 2, when the support unit 2 is pressed down by the user, the ground can also assist in providing support through the ground and reduce the force that the support unit 2 bears. Therefore, the element of the present invention is less prone to damage and has a longer service life. long. In addition, when the support unit 2 is in the open position, the second joint set 24 of the linkage mechanism 21 and the telescopic mechanism 22 can be separated from the first joint set 23 together and used as crutches, providing users with mobility problems Support.
