Description

The present invention relates to a movable protective fence that is convenient to move, and is composed of an upper folding device and a lower folding device, a pulling rope, a second lower folding device, and a frame. The present invention relates to an apparatus that can be reduced in volume and that has a wheel installed at the bottom end of a frame and that can pull a movable protective fence to an arbitrary place and can be safely used without being pinched when folded.

In the conventional infant play bed, the folding frame of the infant play bed is expanded and folded by the folding structure of the infant play bed, and the infant play bed has a first base set on the base and A second base seat set at the lower end on one side of the folding frame is pivotally attached, and a folding set at the lower end on the other side of the folding frame is connected to the first base set and the second base on the other side. There is a knuckle set pivotally attached to the seat set, and the knuckle set is composed of a pair of fittings, a positioning component and an elastic element, and the positioning component is arranged when the folding set is deployed. Held by the elastic element between the pair of fittings, the folding set is restricted to be folded, and there is a driving part, which is movably pivoted to the folding set, Move the part so that the stereotactic part is positioned between a single fitting Thus, after the folding set is folded, the first base set and the second base set are interlocked with the folding frame being folded, and the parts are folded. The volume is large and the user is often pinched in the folding process, which is not practical in use.

An object of the present invention is composed of an upper folding device and a lower folding device, a pulling rope, a second lower folding device, and a frame, and when used, the movable protective fence is quickly folded by the pulling rope and folded. It has a smaller volume and can be moved freely by a wheel installed at the bottom end of the frame, and when folded, above the lower folding device and the second lower folding device, respectively, Since the second spring is installed, it can be prevented from being damaged by being accidentally folded as the second safety device, so that a movable protective fence that is practical and convenient to move can be provided.

A movable protective fence according to the present invention, which is convenient for movement, is composed of an upper folding device, a lower folding device, a pulling rope, a second lower folding device, and a frame, characterized by an upper folding device, a main body and a folding block, It is composed of a sliding block, elastic body, fixed stopper and folding spring, and is provided with a bowl-shaped concave tank that is assembled by fitting the folding block below the main body, and a sliding tank is installed in the middle part. A folding tub is provided in which the sliding block is fitted and fixed at a place where the sliding blocks are fitted to each other, the folding block is folded and fixed by the lower end of the sliding block, and a fixing tub for fixing the tow rope to the upper end is provided. The lower folding device is installed and the sliding block is automatically recovered by the elastic body, and the lower folding device located on the bottom edge of the frame A second lower folding device comprising a pulling line for connecting the device, a folding structure and a second spring, the folding structure is installed on both sides of the lower end of the frame, and the second spring is installed in the folding structure; A frame composed of a plurality of pipes is contained.

As shown in FIG. 1, the movable protective fence according to the present invention is composed of an upper folding device 1, a lower folding device 2, a pulling rope 3, a second lower folding device 4, and a frame 5. The folding device 1 is assembled around the upper end of the frame 5, whereby the upper end of the frame 5 is folded, and the lower folding device 2 includes a main body 21, a folding block 22, a sliding block as shown in FIGS. 2 and 3. 23, an elastic body 24, a fixed stopper 25, and a folding spring 26. The main body 21 is a block body having an arc shape at one end, and a concave tank 211 having a square shape is provided below the main body 21, thereby The folding block 22 is fitted, and a sliding tub 212 is installed in the middle part of the main body 21, whereby the sliding block 23 is slidably installed, and the folding block 22 is installed. These are block bodies that can be fitted to each other in contrast to the left and right sides, and the outer ends of both the left and right folded blocks 22 are both installed in the frame 5, and the sliding block 23 is fitted at a position where they are fitted to each other. When the folding tank 221 for fixing together is installed and the lower end of the sliding block 23 is folded, it is for fitting the folding block 22, and for fixing the pulling rope 3 to the upper end. The fixed tank 231 is installed, and the elastic body 24 is a part for automatically recovering the sliding block 23, and the fixed stopper 25 is installed on one side of the sliding tank 212 of the main body 21. The moving block 23 can be prevented from falling off, and a folding spring 26 is installed above the lower folding device 2 to increase the pressure so that the lower folding device 2 is erroneously operated. The plastic cover 261 is provided outside the folding spring 26 so that the cloth body 52 of the frame 5 can be sandwiched when folded. 3 is a connecting part for connecting the lower folding device 2 on both sides at the bottom end of the frame 5, both ends are installed in the lower folding device 2 on both sides of the frame 5, and the second lower folding device 4 is shown in FIG. The folding structure 41 and the second spring 42 are configured as described above, and the folding structure 41 is installed on both sides of the lower end of the frame 5 to prevent accidental folding by increasing the pressure above the folding structure 41. The second spring 42 is installed, and the spring cover 421 is installed on the second spring 42, so that the cloth body 52 of the frame 5 is not pinched when folded, and operates smoothly. The frame 5 is composed of a plurality of pipes as shown in FIG. 6, and wheels 51 are installed at the lower ends of two corresponding upright frame bodies of the frame 5, whereby the frame can be arbitrarily moved, The cloth body 52 is covered on the outside of the frame 5, and the engaging tool 521 is installed around the cloth body 52, so that when the frame 5 is folded and stored, the frame 5 can be engaged and fixed, When the protective fence moves, it will not fall off.

As shown in FIG. 1, the movable guard fence that is convenient to move is provided with the upper folding device 1 on the horizontal bar above the frame 5, and the lower folding device 2 and the second folding on the horizontal bar below the frame 5. A device 4 is installed, and a pulling rope 3 is installed between the lower folding devices 2.

When using the movable protective fence that is convenient to move, as shown in FIGS. 4 and 5, when the movable protective fence is first folded, the lower folding device 2 is interlocked by pulling the pulling rope 3, and the lower folding device 2 The sliding block 23 is pulled in conjunction with the pulling rope 3, whereby the sliding block 23 urges the elastic body 24, and the two folding blocks 22 cause the both sides of the bottom of the frame 5 to rise upward. Further, both sides of the upper side of the frame 5 are folded in the middle, and both sides of the frame 5 approach each other and are engaged with each other by the male and female engaging members 521 of the cloth body 52 as shown in FIG. Moreover, since the wheels 51 are installed below the frame 5, as shown in FIG. 7, at this time, the movable protective fence can be moved and stored in another position, and the movable protective fence is completely folded and stored. Figure 8 As described above, in bamboo pulling the folded structure 41 of the second folding device 4 onto both sides of the frame 5 is further folded as shown in FIG.

By making the folding into both stages, the first stage can be moved conveniently by folding and approaching both sides of the frame 5, and when folded, the second spring 42 of the second lower folding device 4 can be moved. It is possible to resist pulling by the pulling rope 3 by urging, and the bottom portion of the frame 5 is folded at the same time, so that the folding can be performed smoothly, and the second lower folding device 4 can be stored for a long time by the second stage. By pulling up, both sides of the frame 5 can approach closely without gaps.
