Description

Baby room with folding structure {Folding baby room}

The present invention relates to a baby room having a folding structure, and more particularly, to minimize storage volume by folding and folding in a one-touch manner without separating walls constituting the baby room.

In general, because infants who are crawling or who have just learned to walk have a weak thinking ability, various safety accidents can occur while their guardians are not paying attention and are vigilant.

Therefore, the baby room is used to provide a safe play space for these infants and toddlers, and the baby room secures a play space while forming a fence by combining several walls and assembling them in the form of a fence. It is a structure that becomes

That is, since the fence itself is too bulky to be transported, it is provided so that the user can directly assemble and use it at the site where the user wants to install it using several separately configured parts.

However, in the conventional baby room, it is difficult for users to install and dismantle because the installation structure of the wall is complicated. It's a lot of difficulties.

Therefore, recently, products with a simplified installation structure have been proposed so that anyone can easily and simply assemble the assembly structure by inserting the assembly structure into a shaft, and products with such a simple fitting structure are mainly used.

However, despite this, there is a disadvantage that it takes quite a long time to install alone at home, and disassembly takes as long as installation time. The installed state will remain as is.

However, the baby room needs to secure as much space as possible in order to freely engage in the activities of infants and young children, and because of this, the proportion of the space occupied by the baby room in the indoor space is excessively large, so there is a problem in that the utilization of the indoor space is very poor.

In addition, there are cases in which a baby room must be removed to secure space when a guest visits or works in the house. In this case, it is very cumbersome and takes a long time to separate the baby room. It is very cumbersome to store and inconvenient to use.

The present invention is intended to solve the above problems, so that the fence can be easily folded and stored without separating the fence in the state where the baby room is installed, as well as the folding structure is made simple with one touch.

The present invention as a technical idea for achieving the above object is provided in a baby room in which a plurality of wall plates are provided, and wall plates adjacent to each other are assembled at the side of the wall plates as connecting means to be connected and installed in the form of a fence, the connecting means It includes brackets provided on both sides of the wall plate and a connection guard that allows the wall to be extended by assembling the two brackets in a state where the wall plate is adjacent to each other, and the connection guard is spaced apart from each other. The parts are formed, but the brackets are shaft-coupled to each shaft coupling part by the locking shaft so that the wall plates adjacent to each other can be unfolded in a horizontal state or folded over each other while securing a rotatable variable angle of the wall plate, and the locking The shaft forms first and second locking parts, and the bracket and the connection guard form a locking part so that the first and second locking parts are respectively engaged, and the locking shaft receives elastic restoring force by the elastic element to reciprocate while operating the first and second locking parts. It is designed so that it can be fixed by hanging on the hook or released.

According to the baby room of the present invention, the assembly structure of the fence is simple, and it is very convenient to use because it can be easily expanded or folded using a one-touch button method without separating the fence when unfolding or folding the baby room.

In addition, since it can be folded and stored, space can be efficiently utilized and, of course, it can be stored conveniently without the need for a separate storage bag or box.

In addition, since there is no need to separate the wall, assembly parts can be prevented from being lost in the process of disassembly, assembly, and storage. It is possible to reduce logistics costs by simplifying and minimizing the volume in the distribution process, and consumers can easily unfold and use the baby room without having to assemble it separately.

In addition, it is possible to set the angle of inclination of the wall in various ways, it is very easy to adjust the angle, and it is possible to maintain the angle adjustment state firmly. It can be used by transforming the fence of the room into a unique shape or changing it into various shapes according to the structure of the indoor space.

The baby room of the present invention is to divide a play space of a certain size by assembling several wall plates 100 and connecting them in the form of a fence. It is possible to connect a plurality of wall plates (100) adjacent to each other to connect and install a plurality of wall plates as one fence, and easily foldable without separating the wall plates (100) constituting the fence in the state where the baby room is installed. It is unique in that it can be folded and stored.

The shape of the wall plate 100 may be made of a square or rectangular plate-like structure, and may be configured in various other shapes and designs, such as changing the shape of the wall plate 100 or implementing a pattern.

In addition, by configuring the size (width) of the wall plate to be different, it is possible to assemble it with various options when assembling the wall plate. It can be.

Hereinafter, specific embodiments of the present invention will be described in detail in conjunction with the accompanying drawings.

1 is an external perspective view of the baby room of the present invention installed, FIGS. 2 to 5 are views showing the assembly structure of the baby room, FIG. 6 is the operating structure of the connecting means 200, FIG. 7 is the present invention A drawing showing the folding structure of the baby room, referring to the drawings, the baby room of the present invention is provided with connecting means 200 on both sides of the wall plate 100 so that several wall plates 100 can be connected and assembled together , By using the connecting means 200, several wall plates 100 are connected in parallel with each other adjacent wall plates 100 to form a fence shape.

The connecting means 200 is to be able to adjust or select the connection angle by assembling the wall plate 100 in an axial structure, and look at these connecting means in detail.

The connection means 200 may include brackets 220 formed on both sides of the wall plate 100, and a connection guard 240 for connecting the brackets 220.

The connection guard 240 connects the two brackets 220 disposed to face each other in a state where the wall plates 100 are disposed adjacent to each other in parallel using the connection guard 240, and the adjacent wall plate 100 ) are connected to each other.

To this end, a shaft coupling portion 222 penetrating up and down is formed in the bracket 220, and the connection guard 240 is spaced apart from each other at a position corresponding to the shaft coupling portion 222 of the bracket 220. Two shaft coupling parts 242 are formed, and the shaft coupling portion 222 of the bracket 220 is shaft-coupled to the two spaced apart shaft coupling parts 242 by the locking shaft 260 to form the wall plate 100. It is configured so that the wall plates 100 adjacent to each other can be unfolded in a horizontal state or folded over each other while securing a variable rotational angle.

At this time, the bracket 220 and the connection guard 240 are assembled together to enable idle rotation so that the rotation operation between the bracket 220 and the connection guard 240 is enabled as the locking shaft 260 moves up and down, or It is possible to control the rotation operation, and as a structure for assembling the bracket 220 and the connection guard 240 in idle rotation, the fastening part 226 is formed to protrude in a cylindrical shape on the top of the bracket 220, and corresponds to this. A fitting part 246 engaged with the fastening part 226 is also provided at the lower part of the connection guard 240 to have a groove and protrusion structure on the outer periphery of the fastening part 226 and the inner periphery of the fitting part 246, respectively. By being assembled by interlocking by force fitting, it is simply assembled by the interlocking part, so that the bracket 220 and the connection guard 240 can be configured to idle without the need for separate fastening parts.

At this time, in configuring the fastening part 226 as a groove and forming the fitting part 246 as a protrusion, as shown in FIG. 3, the protrusion constituting the fitting part 246 is not formed on the entire inner circumferential surface, but a part thereof. If formed only on the bracket 240, it can be easily assembled when the bracket 220 is inserted into the connection guard 240 in a pressurized manner. By enabling it, it is possible to separate and wash the assembly parts.

In addition, in forming only a portion of the inner circumferential surface of the protrusion constituting the fitting portion 246, by forming a length exceeding half of the inner diameter, that is, a semicircle, it is possible to prevent it from falling arbitrarily during idling and to facilitate assembly and separation.

In addition, the locking shaft 260 is formed with first and second locking parts 262 and 264, and the bracket 220 and the connection guard 240 are formed with hooking parts 224 and 244 so that the first and second locking parts are respectively engaged. The locking shaft 260 receives elastic restoring force by the elastic element 280 and operates reciprocally, fixing the first and second locking parts 262 and 264 to the locking parts 224 and 244 or releasing the locking state to open the baby room. Even if the wall plate is not separated in the installed state, the installation state can be released easily by folding, so that the indoor space can be efficiently used.

At this time, the hooking part 224 formed in the bracket 220 is composed of a slot hole 225 cut up and down, and the first locking part 262 is a protrusion that is inserted into the slot hole 225 and slides up and down. (264a), the slot hole 225 and the protruding part 264a are formed radially along the outer periphery of the locking shaft 260, and a plurality of slot holes 225 and the protruding part 262a are engaged in a locked state. It is possible to make the slide work stably while making it solid.

In addition, the locking part 244 formed on the connection guard 240 has a concave-convex surface 245 formed in a plurality of toothed structures on the inner diameter of the shaft coupling part 242, and the second locking part 264 has the concave-convex surface. By forming the concave-convex surface 264a with a plurality of tooth teeth structure to engage with the face 245, the tooth teeth are engaged to block rotation.

That is, when the concave-convex surface 264a of the locking shaft 260 is engaged with the concave-convex surface 245 of the connection guard 240, the bracket 220, the connection guard 240, and the locking shaft 260 are engaged with each other and rotated arbitrarily. To prevent this, the fence is firmly fixed, and on the contrary, when the state in which the concave-convex surface 264a of the locking shaft 260 is engaged with the concave-convex surface 245 of the connection guard 240 is released, the bracket 220 and the locking shaft ( Since only 260 maintains an engaged state and the connection guard 240 rotates freely, it is possible to rotate the wall plate 100.

Therefore, since it is configured to unfold horizontally at 180 °, configure the wall edge at a right angle of 90 °, or overlap and fold each other at 360 °, even if the wall plates 100 are not separated from each other while the baby room is installed, the connection guard By (240), the wall plate 100 can be stacked and folded in multiple stages.

And when the wall plate 100 is unfolded and used, the angle at which the wall plate 100 is folded is the meshing structure of the second locking part 262 of the locking shaft 260 and the shaft coupling part 242 of the connection guard 240. As can be implemented by, since it can be installed at 180 ° or folded up to 360 °, the expansion of the variable width of the installation angle of the wall plate 100 is made at very various angles within that range. 2. When the pitches of the concave-convex surfaces 264a and 245 of the locking part 264 and the coupling part 242 are radially arranged, various angles can be set by adjusting the quantity so that the adjustment can be made at the set angle.

For example, if the concavo-convex surface is formed with 36 teeth meshing structures radially, it is possible to set it by 10 degrees, and by adjusting the number of teeth, several angles such as 90 degrees, 135 degrees, 180 degrees, 225 degrees, 270 degrees, etc. set a specific installation angle, or the installation angle is equivalent to 30°, 60°, 90°... If it is arranged to be divided into equal angles, etc., the angle set state can be firmly fixed while the locking shaft 260 is engaged and fixed in a state where the angle is adjusted corresponding to the angle, and the coupling angle of the wall plate 100 Even if an external force acts in the set state, it can prevent the shape of the fence of the baby room from being deformed.

At this time, the length of the upper and lower unlocking section of the second locking part 264 is relatively shorter than the length of the upper and lower unlocking section of the first locking part 262, so that the locking shaft 260 It is possible to adjust the angle of the wall plate 100 while rotating between the bracket 220 and the connection guard 240 while maintaining the fixed state of the bracket 220 .

That is, if the length of the upper and lower unlocking section of the second locking part 264 is relatively shorter than the length of the upper and lower unlocking section of the first locking part 262, the assembly and operation structure of the locking part The second locking unit ( Even if the locking state of 264) is released, the locking state of the first locking part 262 is maintained as it is, and since the angle of the wall plate 100 can be adjusted in that state, after folding or unfolding the wall plate, the locking shaft 260 ) is returned to the original position, and the first and second locking parts are simultaneously engaged again, limiting the folding movement of the wall plate.

Therefore, in the process of unfolding or folding the wall plate, the locking state of the first locking part 262 is not lost, and since the lifting operation is performed only within the slot hole 225, it can be used stably and prevent malfunction of the operating part. .

In addition, the bracket 220 may be formed integrally with the wall plate 100, but in order to produce a baby room with a lightweight structure, shock absorption and low cost, the wall plate 100 is manufactured by blower molding This is preferable, since durability may be reduced when the bracket 220 is integrally molded with the wall plate 100, the bracket 220 is made of a structure separated from the wall plate 100 so that only the bracket 220 is separately It is preferable to manufacture by injection molding.

That is, in order to configure the bracket 220 as a separate type, a mounting portion 120 may be formed in the wall plate 100, and the mounting portion 120 is formed to be inserted from both sides of the upper end of the wall plate 100 so that the bracket The locking shaft 260 mounted on the 220 can be mounted so that it can be rotated by the connection guard 240 by positioning it at the front end so as to be close to the outermost sides of both sides of the wall plate 100. At this time, the bracket 220 ) By inserting the locking shaft 260 and the elastic element 280 sequentially into the lower side of the wall plate 100, the bracket 220 is fixed to the mounting portion 120 of the wall plate 100, and the assembly is simply performed, and the connection guard 240 The bracket 220 may be rotated from both sides toward the center.

In order to ensure that the bracket 220 is firmly mounted on the mounting portion 120 and is not deformed even when an external force is applied, a fitting portion 121 is provided in the mounting portion 120 so as to protrude outward from the mounting portion formed inside the mounting portion 120, and the bracket 220 In this case, a holder 221 is formed so as to be engaged with the cross section of the fitting part 121 to support the edge by fitting it in the lateral direction, and even when the bracket 220, which is an injection molding product, is mounted on the wall plate 100, which is a blow molding product, it is more firmly fixed. be able to do

At this time, the connecting means 200 may be provided on one or more of the upper or lower side of the wall plate 100, and preferably, the locking shaft 260 and the elastic element 280 are sequentially attached to the bracket 220. After fitting, it is assembled to the mounting part 120, and the wall plates 100 are placed in an upright state in parallel by inserting the connection guard 240 in a state where the two wall plates 100 are placed adjacent to each other so that assembly can be easily performed. can be made

In addition, when the connecting means 200 is formed on the upper side, a rotation guide 300 can be provided at the lower end of both sides of the wall plate 100 so that the wall plate 100 can rotate around an axis, The rotation guide 300 forms a hinge axis 320 to be positioned on the same axis as the locking axis 260, and adjusts the angle while the wall plate 100 is installed in an upright state or twists when folded into a folding structure To prevent this, it can be supported by shafts at the top and bottom to make rotation.

At this time, a support guard 340 may be provided to enable rotation of the wall plate in a state in which the hinge shafts 320 of the two adjacent wall plates 100 are seated apart from each other as described above.

That is, shaft fitting parts 342 formed in the form of holes or grooves are formed in the support guard 340 at spaced intervals, so that the rotation of the wall plate 100 is possible while the shaft rotation is made by inserting the hinge shaft 320 do.

At this time, if the shaft fitting portion 342 formed on the supporting guard 340 is made in the form of a groove with a supporting surface formed on the lower side, the wall plate 100 is seated on the supporting guard 340 to the lower side Since the load is generated, the support guard 340 is closely seated on the floor.

The support guard 340 may be further provided with a non-slip element 360 to fix the state in which the wall plate 100 is installed.

The non-slip element 360 may be configured by attaching a pad such as rubber or silicone to the lower end of the support guard 340, and more preferably, a suction-type rubber pad is mounted and pressed to the lower side by the load of the wall plate 100 When the suction type rubber pad is adsorbed on the bottom surface, it can be prevented from flowing.

In addition, this adsorbent rubber pad can prevent the flow of the wall plate 100 as well as adjust the angle-adjusted state of the wall plate 100, and the wall plate 100 connected next to each other according to the angle of engagement. By allowing the connection angle to be adjusted and selected, the baby room can be configured in various forms by connecting them at an angle desired by the user.

Meanwhile, FIGS. 8 to 10 are diagrams showing an assembly structure according to another embodiment of the connecting means 200 of the present invention, further comprising a positioning guide 270 for inducing the movement of the locking shaft 260. can be configured.

To this end, the first slot hole 225a and the second slot hole 225b of the hooking part 224 formed on the bracket 220 have different heights, and repeat along the circumference of the shaft coupling part 222. Arranged, and the locking shaft 260 is equipped with a position guide 270 that rotates the locking shaft every time the locking shaft is pressed to switch the upper and lower height positions, and the position guide 270 is a protruding part 272 ) is formed and the protrusion is selectively inserted into the first slot hole 225a or the second slot hole 225b to limit the depth at which the locking shaft 260 is inserted upward, thereby forming the second locking shaft formed on the locking shaft 260. It is possible to control the angle adjustment state of the bracket 220 mounted on the wall plate 100 with one touch by allowing the part 264 to be caught or released from the hooking part 244 of the connection guard 240.

And, while the position guide 270 rotates, the locking shaft 260 and the position guide 270 move up and down so that the protrusions 272 are alternately inserted into the first and second slot holes 225a and 225b. Rotation guide parts 266 and 276 having inclined surfaces engaged therein may be formed.

Therefore, as shown in FIG. 11, the rotation of the wall plate 100 may be possible by pressing the locking shaft 260, or the rotation may be restricted so as not to be possible.

That is, as shown in FIG. 13, when the locking shaft 160 is pressed, the locking shaft 260 and the positioning tool 270 descend while being supported by the elastic element 280, and the protrusion of the positioning tool 270 ( 272) escapes from the first slotted hole 225a, and at this time, the rotation guide parts 266 and 276 act by the elastic restoring force of the elastic element 280, and the protruding part 272 of the positioning guide 270 is finely rotated. is guided to the second slot hole 225b.

At this time, since the elastic restoring force of the elastic element 280 no longer reaches the locking shaft 260 when the protrusion 272 is seated in the second slot hole 225b, the second locking portion 264 of the locking shaft 260 It is not bound to the hooking part 244 of the connection guard 240, and the wall plate 100 can be freely rotated so that the wall plate 100 can be folded or unfolded at a required angle.

And in the state in which the angle adjustment of the wall plate 100 is completed, as shown in FIG. 14, pressing the locking shaft 160 once again causes the position guide 270 to escape from the second slot hole 225b, At this time, the rotation inducing parts 266 and 276 act by the elastic restoring force of the elastic element 280 to guide the protruding part 272 of the positioning guide 270 to the second slot hole 225a while being rotated minutely.

At this time, when the protrusion 272 is inserted into the first slotted hole 225a, the elastic restoring force of the elastic element 280 enables the locking shaft 260 to be deeply inserted into the upper side, and the second As the locking part 264 is bound to the hooking part 244 of the connection guard 240, the rotational operation of the wall plate 100 is limited, and the angle-adjusted state can be firmly maintained.

Therefore, when the user unfolds or folds the wall plate 100, after pressing the locking shaft 260 once, the wall plate is rotated to adjust the angle between the adjacent wall plates, and when pressed again, the rotation of the wall plate is limited Since the angle of the rotated state can be fixed, the baby room can be easily unfolded and folded by a one-touch operation.

On the other hand, the wall plate 100 may be configured to include a small number of special wall plates 100a having a relatively wider width than other wall plates among a plurality of wall plates.

For example, a special wall plate (100a) is placed in the baby room, and a door (D) is mounted on the special wall plate (100a) to enable entry and exit.

At this time, a plurality of special wall plates 100a may be configured, and in this case, one or more of the special wall plates may be equipped with a door D to enable entry and exit.

In addition, when the baby room is to be installed in a left and right symmetrical shape, such as a rectangular or circular fence, when a special wall plate 100a is placed on the front and rear walls of the baby room, the left and right wall plates (100) Since the configuration is formed to be the same, the left and right wall plates 100 are folded and accommodated between the front and rear walls, so the folding volume of the baby room can be minimized.

In particular, the wall plate constituting the side wall is formed relatively smaller than half of the left and right widths of the special wall plate, so that when the baby room is folded in a left and right symmetrical state, the wall constituting the side wall as shown in FIG. The plate can be folded so that it overlaps between the front and rear walls.
