Background technique

People have used mosquito nets and mosquito nets for thousands of years, and the mosquito nets and mosquito nets have been continuously improved. Especially in the past two decades, innovative products have sprung up. Current popular mosquito nets and mosquito nets have many shortcomings that need to be improved: some mosquito nets will be fixed from the wall or on the ceiling, and this mosquito net limits the movement of the bed and destroys the structure and attractive in appearance of the house. When drilling, the room is full of dust and penetrates everywhere, which is annoying. The high-decibel noise emitted by the impact drill is very harsh, which arouses the disgust of neighbors; some mosquito net frames are supported by four columns, which are respectively located at the four corners of the bed. Hanging on the tent hooks on the pillars, people's activities in the room during the day are severely hindered, and people feel very uncomfortable and uncomfortable; the space inside the tent is not large, and the top of the mosquito net hangs down, making the space inside the tent even narrower, and people feel depressed on the bed The curtains overlap at the tent door, not only the air circulation in the tent is blocked, but also it is inconvenient to get on and off the bed, especially when you have to use one hand to open the curtains wrapped around your head when you are holding your baby on and off the bed, it is very troublesome; Mosquito nets cannot be fully contracted. Once mosquitoes enter the net, it is not easy to drive them out. You drive them on the left to fly to the right, and you drive them on the top of the tent to hide them on the curtain; some mosquito nets only have one door. The relative position of the door can only be changed from one side of the bed to the other, or can only be changed from one end of the bed to the other, which is inconvenient to use. As the tent door of the mosquito net on the high and low bed is positioned at the longitudinal center of the bed, and the bed ladder is close to the end of the bed, it is very inconvenient for people who sleep on the bed to get on and off the bed; On the contrary, it increases the overlapping of the tents, and also increases the way for mosquitoes to fly into the tent; children standing on the floor cannot hang the tents on the hooks, and it is very unsafe to operate while standing on the bedside. Parents strictly prohibit it. If things go on like this , which not only limits the development of their self-care ability, but also promotes the formation of dependent thoughts. Though current popular mosquito net frame and mosquito net have improvement, above-mentioned shortcoming does not all eliminate.

The two vertical sides of the tent are provided with joint locking devices, and the second preferred scheme of the structure of the joint locking device is such that the two vertical sides of the tent are joined by a zipper, and the two sides of the zipper can be completely separated .

When the two vertical sides of the tent are fastened to the magnetic pieces, in order not to damage the two vertical sides and to prevent the magnetic pieces from falling off, a strip is sewed on each of the two vertical sides of the tent. Ribbons, sew magnetic sheet pockets on multiple corresponding positions of the two webbing ribbons respectively, place a magnetic sheet in each magnetic sheet pocket, and bag mouth is closed.

When the two vertical sides of the tent are connected by zippers, in order not to damage the two vertical sides, a webbing is sewed on each of the two vertical sides of the tent, and then sewed on the two webbings. zipper.

After adopting such a structure, since the track-type mosquito net frame is installed on the bed, there is no need to drill holes on the wall or the ceiling when the track-type mosquito net frame is installed, thereby eliminating noise and dust pollution caused by drilling, the structure of the house and The beauty is not damaged, and the bed with track-mounted mosquito net frame can be moved.

After adopting such a structure, the roofless bed located on the floor, the bracket supporting the slide rail frame is installed at the head of the bed or close to the head of the bed, and the curtain can be retracted to the head of the bed. The hindrance and limitation of activities in the room where the bed is located are small, the upper limbs can be fully stretched, and the room is well lit.

After adopting such a structure, since the tent top of the mosquito net is tiled on the top of the slide rail frame, the tent top is level and smooth, and the space in the tent is spacious.

After adopting such a structure, since the two vertical sides of the tent are joined together, the tent door is closed, so there is no overlapping of the tent, the air in the tent is circulated, and it is very convenient to get on and off the bed, especially when holding a baby. Turn your head around, close and lock the tent door after getting on and off the bed, so that mosquitoes will not enter the tent.

After adopting such a structure, mosquitoes entered the mosquito net hanging on the floor without a roof. First, the curtain was shrunk to the head of the bed and shaken. The curtain was fully opened, and the hiding place of the mosquito was significantly reduced, so the mosquito had to fly away. When the curtains are closed, there are no mosquitos in the tent. If the mosquito stays on the top of the tent when repelling, it is easy to eliminate or drive away the mosquitoes because the top of the tent is flat and can be seen at a glance.

After adopting such a structure, the relative position of the tent door can be selected arbitrarily, and it is also very simple to change after being selected. Only the relative position of the tent door has just changed by rotating the tent curtain together with the track wheel frame relative to the slide rail frame.

After adopting such a structure, opening and closing the curtain can be realized only by pulling the curtain and moving the track wheel frame. Because the rolling friction force is very small, and because the hands are not raised high, not only the adults feel light and convenient, but also the children feel easy. This is also beneficial to developing children's self-care ability and preventing the generation of dependent thoughts.

After adopting such a structure, the tent door of the upper and lower beds can be opened to the position of the bed ladder, which not only brings convenience to the user to get on and off the bed, but also is safe.

As shown in Figure 3, the top surface of one of the two short straight rails 15 on the slide rail frame 1 is firmly connected with two top loading codes 8, wherein one top loading code 8 is close to the inner side, and the other top loading code 8 Code 8 is positioned at the middle thereof, and the protruding end of one of these two top-loading codes 8 protrudes outwards. The top-loading code 8 on the two straight rails with short length on the slide rail frame 1 is placed on the cross bar 6 of one of the two supports 4 respectively. After the top loading code 8 on the slide rail frame 1 is firmly connected with the cross bar 6 at the corresponding position, the slide rail frame 1 is just firmly suspended directly above the topless bed on the high and low beds.

Description: The topless bed located on the high and low beds focuses on the pursuit of easy installation and simple structure of the supporting device. Though above-mentioned two kinds of structures all will be processed to existing bed, unavoidable.

Its three, the structure of the supporting device on the top bed:

As shown in Figure 4, the support device on the top bed is a top-loading code 8, and at least three top-loading codes 8 are fixedly connected to the top surface of the upper rail 15 of the slide rail frame 1, and these top-loading codes 8 are separated from each other, and they protrude End protrudes inwards. After the upper surfaces of these top loading codes 8 are respectively firmly connected with the lower surfaces of the top boards of the top bed at the corresponding positions, the slide rail frame 1 is hung firmly on the top board of the top bed.

Explanation: The supporting device on the above-mentioned bed with a roof adopts the top-mounted code 8. Since the protruding end of the top-mounted code 8 protrudes inward, the area of the slide rail frame 1 is relatively large. Since the connection between the top loading code 8 and the top plate is relatively easy, this structure should be preferred when the top loading code 8 can be firmly connected on the top plate. If three top loading codes 8 are fixed on the top surface of the track 15 of the slide rail frame 1, then one is fixedly connected to each of the straight rails 15 with a large length on the inner side of the slide rail frame 1 and two small straight rails 15 with a small length. The top loading code 8 on the straight track 15 with a small length is close to the outside; if four top loading codes 8 are fixed on the top surface of the track 15 of the slide rail frame 1, then on the straight track 15 with a large length inside the slide rail frame 1 Two are fixedly connected, and one is respectively fixedly connected on the small straight rails 15 of the two lengths, and the top loading code 8 on the small straight rails 15 of the length is near the outside.

As shown in Figure 5, the support device on the top bed is or side-mounted code 13, and at least three side-mounted codes 13 are firmly connected on the top surface of the track 15 on the slide rail frame 1, and these side-mounted codes 13 are separated from each other. And its external mounting end 13a protrudes outward; After the external mounting ends 13a of these side loading codes 13 are fastened and connected respectively on the inner bed frame above the top bed at the corresponding position, the slide rail frame 1 is just firmly suspended on the On the inner bed frame above the canopy.

Explanation: The support device on the above-mentioned roofed bed adopts the side mounting bracket 13. Since the external mounting end 13a of the side mounting bracket 13 protrudes outward, the area of the slide rail frame 1 is relatively small, which is its shortcoming. This structure is only adopted under the situation that the top loading code 8 cannot be firmly connected on the top plate. If three side mounting codes 13 are fixed on the top surface of the track 15 of the slide rail frame 1, then one is respectively fixedly connected on the straight rail 15 of the inside length of the slide rail frame 1 and on the two small straight rails 15 of the length, The side mounting code 13 on the straight track 15 with a small length is close to the outside; if four side mounting codes 13 are fixed on the top surface of the track 15 of the slide rail frame 1, then the inside of the slide rail frame 1 grows up on the straight rail 15. Two are fixedly connected, and one is respectively fixedly connected on the small straight rails 15 of two lengths, and the side loading code 13 on the small straight rails 15 of the length is near the outside.

Under the situation that the support device on the roofed bed is a top loading code 8, as shown in Figure 4, the fastening connection between the top loading code 8 and the top plate of the top bed is achieved by the attraction of the top loading code 8 by magnets. The top loading code 8 is made of a magnetic material, and the top plate corresponding to the top loading code 8 is firmly connected with a magnet. Slide rail frame 1 is suspended on the top of the bed by the attraction of top loading code 8 and magnet on it.

Under the situation that the support device on the top bed is a side-mounted code 13, as shown in Figure 5, drill in advance on the inner bed frame above the top bed corresponding to the position of the mounting hole on the external installation end 13a of the side-mounted code 13. Insert the latch or pull out the latch to realize the suspension or removal of the slide rail frame 1 in the mounting hole and the drilled hole.

A mosquito net matched with the track-type mosquito net frame is composed of a tent top 20, a curtain 18 and a lace 14.

As shown in Fig. 8 and Fig. 9, the tent top 20 and the tent 18 of the mosquito net are separated from each other. The shape and size of the tent top 20 correspond to the shape and size of the top surface of the slide rail frame 1 that hangs the mosquito net, and the lace 14 is tightly connected around it. The lace 14 has a suitable height, and its texture is soft and wrinkled. The tent roof 20 is flatly covered on the top of the slide rail frame 1 , the top mounting code 8 locks its relative position with the slide rail frame 1 , and the lace 14 hangs down around the slide rail frame 1 . The curtain 18 is unfolded into a rectangle, and the length of its upper end is greater than the perimeter of the slide rail frame 1 . The curtain 18 is suspended on the track wheel frame 2 on the slide rail frame 1 . The two vertical edges of the curtain 18 have engagement locking means.

Explanation: the effect of lace 14 has three, and one is to prevent mosquitoes, and the other is to beautify, and the third is to prevent the top of the tent top 20 from sliding relative to the top of the slide rail frame 1. However, the preventing effect is limited, and it is necessary to install the top loading code 8 to lock the relative position of the tent top 20 and the slide rail frame 1.

The track 15 that surrounds the slide rail frame 1 has a cross section as an I-shaped structure track 15a, and has a cross section as a frame structure track 15b. The connection mode between the curtain 18 and the track wheel frame 2 on the slide rail frame 1 is corresponding to the structure of the track 15 .

One, under the situation that the track 15 of slide rail frame 1 is the I-shaped structure track 15a, as shown in Figure 8, the connection mode of the tent 18 of mosquito net and the track wheel frame 2 on this slide rail frame 1 is like this, The inner side of this tent 18 is sewed with a plurality of horizontal short lines 16 near the upper end, and these short lines 16 are evenly distributed along the tent 18 and are of the same height. The number of 2 is equal. Hang a short line 16 on the axle 2c between the wheel frame 2a and the outer pulley 2b on each track wheel frame 2. When the curtain 18 is pulled along the I-shaped structure track 15a, the pulleys 2b on both sides on the corresponding track wheel frame 2 will roll along the upper surfaces on both sides of the bottom plate of the I-shaped structure track 15a at the corresponding position, thereby realizing the tent curtain 18. 18 The opening and closing of the upper tent door.

Its two, under the situation that the track 15 of slide rail frame 1 is frame structure track 15b, as shown in Figure 9, the connection mode of the curtain 18 of mosquito net and the track wheel frame 2 on this slide rail frame 1 is such, The inner side of this tent 18 is stitched a plurality of hooks 17 near the upper end, and these hooks 17 are evenly distributed and equal in height on this tent 18, and the number of these hooks 17 is the same as that of the track wheel frame on the slide rail frame 1. The number of 2 is equal. Hang a this hook 17 in the aperture 19 of wheel frame 2a middle part on each this track wheel frame 2. When pulling the curtain 18 along the frame structure track 15b, the pulleys 2b on both sides on the corresponding track wheel frame 2 will roll along the upper surface of the bottom plate on both sides of the track groove on the frame structure track 15b of the corresponding position, thereby realizing the The opening and closing of the tent door on the tent curtain 18.

Explanation: Comparing the track 15a with an I-shaped structure in the cross section and the frame structure track 15b in the cross section, the lace 14 is closely matched with the former, and the anti-mosquito effect is better.

In order not to prevent the lace 14 from fully extending downwards, a vertical notch is reserved on the lace 14 at a position corresponding to the top loading code 8 or the side loading code 13 directly installed on the slide rail frame 1 under the tent top.

In order to make the short line 16 on the tent 18 or the connection of the hook 17 and the tent 18 firm, a horizontal soft belt is sewed on the inner side of the tent 18 near the upper end, and then the short line is sewed on the soft belt. 16 or sew the hook 17.

The two vertical edges of the curtain 18 have engaging locking devices, and the structure of the engaging locking devices has two preferred solutions.

The two vertical edges of the curtain 18 are provided with engaging locking devices, and the first preferred solution of the structure of the engaging locking device is such that a plurality of corresponding positions on the two vertical edges of the tent 18 are fastened respectively. The magnetic pieces are connected, and when the two vertical sides are engaged, the magnetic pieces at the corresponding positions attract each other so that the two vertical sides of the curtain 18 will not be separated automatically.

Description: The first preferred solution of the above-mentioned locking device is convenient and quick to use, simple in structure, easy to implement, reliable in locking, and easy to replace. Preschool children can separate the tent door even when they stand on the floor. Can be closed automatically. Can be considered first choice. Only the magnetic strength of the magnetic sheet must be grasped well, if the magnetic force is too strong, the two vertical edges of the tent curtain 18 are not easy to separate, which will easily cause damage;

The two vertical limits of tent curtain 18 have engagement locking device, the second preferred scheme of the structure of this joint locking device is like this, two vertical limits of this tent curtain 18 are joined by slide link, and the two sides of this slide fastener can completely separated.

Explanation: The second preferred solution of the above-mentioned locking device is reliable and beautiful, but it is difficult to replace and inconvenient to use. If a child stands on the edge of the bed to pull the zipper out of curiosity, it may fall to the floor. Even if the two vertical sides of the tent door are close to the zipper after a person gets out of bed, the tent door will not be automatically locked. This program is used for reference.

When the two vertical sides of the curtain 18 are tightly connected to the magnetic sheet, in order not to damage the two vertical sides, and in order to prevent the magnetic sheet from falling off, each slit on the two vertical sides of the curtain 18 Put a piece of webbing on it, sew magnetic pockets on multiple corresponding positions of the two webbings, place a magnetic sheet in each magnetic pocket, and seal the pocket.

Under the situation that two vertical limits of curtain 18 are joined by slide link, in order not to damage these two vertical limits, respectively sew a webbing on the two vertical limits of this tent curtain 18, on these two webbings again Sew on the zipper.

Explanation: Mosquitoes can only fly but not crawl, and it is impossible to climb into the mosquito net from the gap through the double barrier of lace 14 and curtain 18. Using this physiological characteristic of mosquitoes should theoretically prevent mosquitoes. After the sample was made, no mosquito was found to crawl into the mosquito net through use, and practice showed that the anti-mosquito effect was good.

There are mosquitoes in the mosquito net of the bed without top on the floor, and the tent curtain is fully shrunk 18 and then closed, and there is no mosquito in the tent. It shows that it is easy to drive away mosquitoes in the tent. There is a top bed or a topless bed located on a bunk bed. Although the curtain 18 can be retracted to allow the tent door to be fully opened, because the lower parts of the other three directions are pressed under the quilt or mat, the curtain 18 cannot be retracted to the head of the bed, which is easy The advantage of repelling mosquitoes in the tent cannot be brought into play.

After the curtain 18 of the mosquito net on the roofless bed on the floor shrinks, not only does the room appear empty, but the upper limbs can be fully stretched, and the room is brighter. This advantage is very popular with people.

The present invention relates to various beds and two kinds of tracks 15. Track-type mosquito net frames and mosquito nets on standardized beds can be produced in batches, while existing beds or non-standardized beds can only be customized.

The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. The present invention is not limited to the above-mentioned embodiments, and various changes can be made within the scope of knowledge of those skilled in the art without departing from the gist of the present invention. Various changes made without departing from the gist of the present invention still belong to the scope of the present invention.
