Detailed Description
The present invention will be further explained with reference to fig. 5 to 14.
Example 1
Referring to fig. 5, the anti-pinch device of the accompanying chair comprises a first chair back 1 and a second chair back 2, wherein the first chair back 1 is rotatably connected with the second chair back 2 through a rotating connecting piece, the accompanying chair further comprises an arc-shaped anti-pinch piece 6, and two sides of the anti-pinch piece 6 are respectively connected with the first chair back 1 and the second chair back 2 in a sliding manner.
The rotation connecting piece in this embodiment is axis of rotation 4, and the downside of the first back of the chair 1 and the second back of the chair 2 is fixed with the fixed frame of the back of the chair 3 respectively, has seted up the erection joint respectively in two adjacent one sides of the fixed frame of the back of the chair 3, prevents that the both sides limit of pressing from both sides piece 6 is equipped with between the fixed frame of the back of the chair 3 and prevents the 6 stop gear of clamping piece by the erection joint in stretching into the fixed frame of the back of the chair 3.
Referring to 6~7, the anti-pinch piece 6 limiting mechanism is a limiting blocking piece 7 arranged at two ends of the side portion of the anti-pinch piece 6, and the distance between the end portions of the two limiting blocking pieces 7 at the side portion of the anti-pinch piece 6 is larger than the length of the installation gap. When will prevent that piece 6 installs to the erection joint in need utilize the deformation of preventing piece 6 to make and prevent that piece 6 cards are gone into in the erection joint, because the distance between two spacing separation blade 7 is greater than the length of erection joint this moment, so prevent that piece 6 can not follow the erection joint and drop under the condition that does not have external force.
Referring to fig. 8~9, in the process of the first chair back 1 and the second chair back 2 falling to the horizontal state, the anti-pinch sheet 6 stretches into the installation seam along with the swing of the chair back fixing frame 3, when the first chair back 1 and the second chair back 2 swing to the bed state, the anti-pinch sheet 6 is stored to the inner side of the first chair back 1 and the second chair back 2, the anti-pinch sheet 6 is a stainless steel sheet, certain deformation can occur in the telescopic process, and the operation is very convenient.
Example 2
Referring to fig. 10 to 12, in this embodiment, the seat back fixing frames 3 are also fixed to the lower sides of the first seat back 1 and the second seat back 2, the first connecting piece 8 is fixed to the seat back fixing frame 3 on the lower side of the first seat back 1, the second connecting piece 9 is fixed to the seat back fixing frame 3 on the lower side of the second seat back 2, the first connecting piece 8 is rotatably connected to the second connecting piece 9, and the anti-pinch piece 6 is connected between the first connecting piece 8 and the second connecting piece 9.
The clamping piece 6 is prevented in the installation of this embodiment utilizing first connection piece 8 and second connection piece 9, can solve the problem of the fixed frame of the back of the chair 3 corner tong, this is because the fixed frame of the back of the chair 3 is because processing technology's reason usually, the corner is the fillet usually, just so lead to the fixed frame of the back of the chair 6 unable corner of being connected to of preventing in embodiment 1, prevent in the fixed frame of the back of the chair 3 that clamping piece 6 can't contract in the corner, so the middle part of the fixed frame of the back of the chair 3 can prevent that the hand from stretching into in gap 5, but still there is the hand to stretch into the corner and cause the hidden danger of pressing from both sides the wound. The first connecting piece 8 and the second connecting piece 9 are utilized in the embodiment, so that the problem that the anti-clamping piece 6 cannot be installed at the corner can be solved, and the potential safety hazard that clamping injury may be caused at the corner is eliminated.
Referring to fig. 13 to 14, two first mounting columns 10 are arranged on the first connecting sheet 8, two second mounting columns 11 are arranged on the second connecting sheet 9, one side of the anti-pinch sheet 6 is arranged between the two first mounting columns 10, and the other side of the anti-pinch sheet 6 is arranged between the two second mounting columns 11. The chair back fixing frame 3 is formed by connecting two cross beams and two longitudinal beams to form a rectangular frame, a first connecting sheet 8 and a second connecting sheet 9 are fixed at two ends of one cross beam, two ends of a first mounting column 10 are respectively connected with the first connecting sheets 8 at two ends of the cross beam, and two ends of a second mounting column 11 are respectively connected with the second connecting sheets 9 at two ends of the cross beam.
In order to reduce the gap between the first chair back 1 and the second chair back 2 and ensure that the accompanying person is comfortable when lying on the accompanying chair, the cross beam fixed with the first connecting piece 8 and the second connecting piece 9 in the embodiment is positioned at the inner side of the edges of the first chair back 1 and the second chair back 2. And the junction of crossbeam and longeron is the right angle, directly cancels the fillet of the fixed frame 3 corner of back of the chair, adopts the right angle structure, and it is more convenient to install first connection piece 8 and second connection piece 9, and fundamentally has eliminated the potential safety hazard that the corner probably caused the clamp to hinder.
Still be equipped with a support column 12 on first connecting piece 8 in this embodiment, support column 12 sets up between first erection column 10 and second erection column 11, prevents that clamp piece 6 sets up the outside at support column 12. The diameter of first connection piece 8 is greater than second connection piece 9, installs support column 12 on the first connection piece 8 in the second connection piece 9 outside, and it is ejecting to prevent pressing from both sides piece 6 outside when can first back of the chair 1, the mutual folding of second back of the chair 2 through support column 12, and work is more reliable. Of course, the support column 12 can also be mounted on the second web 9.
In order to prevent the anti-slip sheet 6 from falling off from the first mounting column 10 and the second mounting column 11, anti-slip limiting mechanisms are arranged on two sides of the anti-slip sheet 6. The anti-falling limiting mechanism in the embodiment is a limiting folding edge (not shown in the figure), and two sides of the anti-clamping piece 6 are folded inwards or outwards to form the limiting folding edge.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention still belong to the protection scope of the technical solution of the present invention.
