The bed guardrail 10 includes end frames 12 and 14, and upper and lower pole members 16 and 18 engaged between the end frames 12 and 14. The bed fence 10 includes a height direction defined by the direction of extension of the end frame 12 or the end frame 14, a length direction defined by the direction between the end frame 12 and the end frame 14, and a width direction. The height, length and width directions are perpendicular to each other.

The end frame 12 generally includes an upper member 20, a tubular member 22, and a lower member 24. The upper member 20 may be made of, for example, plastic. With further reference to fig. 2 and 3, the upper member 20 has a socket 28 that receives the tubular member 22, the socket 28 fitting over the outside of the tubular member 22 so that the upper member 20 can slide in the height direction along the tubular member 22. The sleeve 28 has a locking slot (not shown) on the inside that can receive a latch 34 at the upper end portion 32 of the tubular member 22 so that the upper member 20 can be locked at the upper end portion 32 of the tubular member 22, the latch 34 can be, for example, a ball tab, and the upper member 20 further includes a push switch 35, the push switch 35 being configured to disengage the latch 34 from the locking slot. Upper member 20 extends longitudinally inward from tubular member 22, and its inner end portion 36 includes a slot 38 and a through-hole 40, slot 38 receiving a left latch 42 of upper rod member 16, and through-hole 40 receiving a lock knob 44 of left latch 42. Preferably, the opening of the slot 38 is upwardly disposed.

The lower member 24 may be made of, for example, plastic. With further reference to FIG. 4, the lower member 24 has a sleeve 46 that receives the tubular member 22. The lower member 24 extends longitudinally inwardly from the lower end portion 48 of the tubular member 22, with an inner end portion 50 thereof being pivotally connected to a left latch 52 of the lower pole member 18 and having a through hole 54, the through hole 54 being adapted to receive a lock knob 56 of the left latch 52.

When the upper member 20 is locked at the upper end portion 32 of the tubular member 22, the tubular member 22 extends substantially heightwise between the upper member 20 and the lower member 24, or its lower end portion 48 may extend further through the sleeve 46 of the lower member 24 by a suitable dimension, typically not exceeding the thickness of most mattresses on the market.

When the left latch 42 is received in the slot 38, the lock knob 44 is received in the through hole 40 to prevent the left latch 42 from being disengaged from the slot 38 from the opening of the slot 38, in such a way that the left latch 42 is locked with the upper member 20. A spring (not shown in the drawings) abuts on the lock knob 44 inside the lock knob 44, the spring being configured to constantly resiliently urge the lock knob 44 toward the position of extending into the through hole 40, in such a way that the lock knob 44 needs to overcome the spring force of the spring to be able to disengage from the through hole 40, when no external force is applied to the lock knob 44, when the left latch 42 is received in the insertion slot 38, the lock knob 44 is aligned with the through hole 40 and the lock knob 44 will extend into the through hole 40 by itself under the internal force of the spring. The knob 44 and through-hole 40 are circular and are disposed along a centerline 78 of the annular flange 70 and annular recess 72, the centerline 78 being disposed generally perpendicular to a plane collectively defined by the end frames 12, 14 in such a manner that the left latch 42 can rotate about the centerline 78 when the left latch 42 is received in the slot 38, in such a manner as to provide a rotatable connection between the upper pole member 16 and the upper member 20. The right latch 66 is substantially identical to the left latch 42, except that it is provided as a mirror image, and the upper rod member 16 is engaged between the end frame 12 and the end frame 14 by the left and right latches 42, 66.

The lever member 68 includes a left lever member 80, a right lever member 82, a left hinge 84, and a right hinge 86.

The outer end portion 92 of the right lever member 82 is joined to the right latch 66 and the inner end portion 94 is joined to the right hinge 86. With further reference to fig. 6, the shaft 96 is engaged between the left and right hinges 84, 86, the shaft 96 having an axis 98 disposed perpendicular to the plane collectively defined by the end frames 12, 14, the left and right hinges 84, 86 being rotatable about the axis 98, in such a manner that the left and right lever members 80, 82 are rotatable about the axis 98. Left stop 100 is provided on left hinge 84, right stop 102 is provided on right hinge 86, left stop 100 and right stop 102 being arranged such that when left hinge 84 and right hinge 86 are rotated about axis 98 to bring left stop 100 and right stop 102 into abutment, left hinge 84 and right hinge 86 are prevented from further rotation while left rod 80 and right rod 82 are prevented from further rotation. With further reference to fig. 7, it is preferred that the left and right stops 100, 102 are arranged such that when abutted against one another, an included angle 104 of less than 180 degrees and greater than 160 degrees centered on the center of rotation of the left and right rod members 80, 82 on the axis 98 can be formed between the left and right rod members 80, 82, and that the opening of the included angle 104 faces downward when the guardrail 10 is installed in normal use with the upper rod member 16 engaged between the end frames 12, 14. Preferably, the included angle 104 is less than 180 degrees and greater than 170 degrees. It is further preferred that the included angle 104 is between 176 and 178 degrees. It should be understood that the left and right rod members 80, 82 form an included angle 106 on the other side of the included angle 104, and that the rotation range of the left and right rod members 80, 82 can be either the range of the included angle 104 or the range of the included angle 106, provided that the opening of the included angle 104 faces downward. Preferably, the left and right rod members 80, 82 are substantially equal in length, so that the length dimension of the two after rotation is minimized. Preferably, as shown in FIG. 6, the left hinge 84 is configured with an insertion slot 107, and the right hinge 86 is at least partially received in the insertion slot 107.

Referring to fig. 1 and 4, the lower rod member 18 includes a left latch 52, a right latch 108, a rod member 110, the rod member 110 being engaged between the left latch 52 and the right latch 108. The left latch 52 is connected to the inner end portion 50 of the lower member 24 by a shaft 112, the shaft 112 having an axis 114 disposed perpendicular to the plane collectively defined by the end frames 12, 14, the left latch 52 and the lower member 24 being rotatable about the axis 114. Lock knob 56 is disposed at a position spaced from shaft 112 and rotatable about axis 114, lock knob 56 being arranged to prevent rotation of left latch 52 and lower member 24 about axis 114 when lock knob 56 is received in through hole 54, while shaft 112 and lock knob 56 are aligned lengthwise. A spring (not shown) abuts on the lock knob 56 inside the lock knob 56, the spring being configured to constantly urge the lock knob 56 elastically toward a position of extending into the through hole 54, in such a way that the lock knob 56 needs to overcome the elastic force of the spring to be able to disengage from the through hole 54, and when no external force is applied to the lock knob 56, the lock knob 56 will extend into the through hole 54 by itself under the internal force of the spring when the lock knob 56 is rotated to be aligned with the through hole 54. The right latch 108 is substantially identical to the left latch 52 except that it is arranged as a mirror image of the other, and the lower rod member 18 is engaged between the end frame 12 and the end frame 14 via the left latch 52 and the right latch 108.

The lever member 110 includes a left lever member 118, a right lever member 120, a left hinge 122, and a right hinge 124. The outer end portion 126 of the left lever member 118 is joined to the left latch 52 and the inner end portion 128 is joined to the left hinge 122. The outer end portion 130 of the right lever member 120 is engaged to the right latch 108 and the inner end portion 132 is engaged to the right hinge 124. The shaft 134 is engaged between the left and right hinges 122, 124, the shaft 134 having an axis 136 disposed perpendicular to a plane collectively defined by the end frames 12, 14, the left and right hinges 122, 124 being rotatable about the axis 136, in such a manner that the left and right lever members 118, 120 are rotatable about the axis 136. The left stopper 138 is provided on the left hinge 122, the right stopper 140 is provided on the right hinge 124, and the left stopper 138 and the right stopper 140 are arranged such that when the left hinge 122 and the right hinge 124 are rotated about the axis 136 to abut the left stopper 138 and the right stopper 140, the left hinge 122 and the right hinge 124 are prevented from further rotation, and the left lever member 118 and the right lever member 120 are also prevented from further rotation. Preferably, the left and right stops 138, 140 are arranged such that when abutted against one another, the rod member 110 is substantially horizontal, i.e., an angle 142 (shown in fig. 9) formed between the left and right rod members 118, 120 centered on the center of rotation of the left and right rod members 118, 120 on the axis 136 may be equal to 180 degrees or close to 180 degrees. Preferably, when guardrail 10 is installed in normal use, the range of rotation of left post 118 and right post 120 is the range of angle 142 and the opening of angle 142 is upward, thus preventing the middle of post 110 from bulging due to the rotation of left post 118 and right post 120 during use. It will be appreciated that when the lock knob 56 is rotated to extend into the through hole 54, the left latch 52 is locked with the left rod member 118 substantially perpendicular to the end frame 12, and similarly, when the right latch 108 is locked with the right rod member 120 substantially perpendicular to the end frame 14. Preferably, the left and right rod members 118, 120 are of equal length so that the length dimension of the two is minimized after rotation.

Flexible guards (not shown) such as protective cloth covers, protective mesh, sleeves, into which the tubular members 22, rod members 68, rod members 110 may be threaded to connect with the guards, are attached to the tubular members 22 of the end frames 12, 22 of the end frames 14, rod members 68, 110, respectively, in such a way that the guards may be removed for cleaning.

Some functions, application scenarios, methods of use or configurations that are advantageous over the prior art of the bed fence 10 are described below. The bed guardrail 10 can have two states, a first state in which it can be normally used, and a second state in which it can be conveniently packaged, stored or transported. When the bed guardrail 10 is assembled and installed on a bed in the first state, the foot member 26 is normally pressed under the mattress, the end frames 12, 14 are supported vertically and spaced apart on the sides of the mattress in the height direction, the lower rod member 18 is horizontally engaged between the lower end portions 48 of the end frames 12, 14 in the length direction, and the lock knob 56 is extended into the through hole 54 to prevent the rotation of both ends of the lower rod member 18, thereby maintaining the stable "right-angled U" shape of the end frames 12, 14 and the lower rod member 18. By adjusting the height of the lower member 24 by pressing the switch 64, the lower rod member 18 can be positioned above and adjacent the mattress, while the extension of the lower member 24 toward the side of the mattress allows the lower rod member 18 to be pressed against the mattress, thus eliminating the gap between the mattress and the barrier 10, and the mattress can provide support below the lower rod member 18 to prevent the left and right rod members 118, 120 of the lower rod member 18 from sinking at the hinge. Upper rod member 16 is engaged lengthwise between upper end portions 48 of end frames 12, 14, and left and right rod members 80, 82 of upper rod member 16 are slightly raised upwardly at the hinge joint in the absence of force due to the angle 104, but because the guard is typically connected in tension between upper and lower rod members 16, 18, upper rod member 16 is subjected to a guard downward force that causes upper rod member 16 engaged between end frames 12, 14 to assume a substantially horizontal lengthwise condition that prevents left and right rod members 80, 82 from sinking at the hinge joint. When the user needs to get in or out of the bed, the upper rod member 16 is connected with the upper member 20 in a rotating mode, so that the upper member 20 can slide down along the tubular member 22 by unlocking the upper member 20 and the tubular member 22 of one of the end frames 12 or 14 through the push switch 35, and the user can get in or out of the bed from the high side and the low side at the moment. When it is desired to fully open the bed guardrail 10, the upper member 20 is slid down the tubular member 22 as the upper rod member 16 is slid down as a whole by simultaneously unlocking the end frames 12, 14 and the corresponding upper member 20. Since the bed guardrail 10 is typically mounted against a mattress, the upper pole member 16 is typically slid down to a position proximate to the mattress, i.e., cannot be slid down, when the upper pole member 16 is positioned above the mattress, which may interfere with a person sitting at the side of the mattress, when the left latch 42 is unlocked from the upper member 20, thereby releasing the engagement of the upper pole member 16 with the end frames 12, 14 so that the upper pole member 16 can be placed in a position under the mattress.

When the bed fence 10 needs to be conveniently packaged, stored or transported, the engagement of the upper rod member 16 with the end frames 12, 14 is unlocked by unlocking the left latch 42 from the upper member 20, and the left rod member 80 and the right rod member 82 of the upper rod member 16 are in a state of being rotatably folded; at the same time, the left latch 52 of the lower lever member 18 is unlocked from the lower member 24, and the end frame 12 and the left lever member 118 are in a state of being folded by rotation, the end frame 14 and the right lever member 120 are in a state of being folded by rotation, and the left lever member 118 and the right lever member 120 are in a state of being folded by rotation. In this manner, the bed fence 10 can be folded to a smaller size for convenient packaging, storage or transport in a second state (as shown in fig. 10).

When the bed fence 10 is in the second state, the lower rod member 18 maintains the connection with the end frames 12, 14, while the upper rod member 16, although disengaged from the end frames 12, 14, maintains the connection of the upper rod member 16 with the lower rod member 18 with the fence arrangement, so that the bed fence 10 remains integral in the second state, which facilitates subsequent installation of the bed fence 10. When the bed guardrail is required to be installed, the end frames 12 and 14 can be automatically locked only by rotating to the position of the vertical lower rod member 18, then the bed guardrail 10 can be installed on the bed by unfolding the upper rod member 16 and the lower rod member 18, the installation process does not need a manual unlocking switch, only the bed guardrail 10 needs to be unfolded, and the problem that most of the bed guardrails in the prior art are complicated to install is solved.

The above description is only a preferred embodiment of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
