Description

[Technical Field]

[0001] The present invention relates to a wall panel structure for an indoor room that is assembled and installed within a building. More specifically, the present invention relates to a wall panel structure that has an entrance without a floor rail and can be used as a nursing room where a stroller can be pushed while entering.

[0002] Specifically, the present invention relates to a wall panel structure in which the opposing contact surfaces of the wall panels to be assembled can be directly connected by sliding them relatively up and down, eliminating the need for corner posts for connection and making it easy to connect wall panels to each other. [Background technology]

[0003] Public facilities and large commercial facilities that are frequented by many people have traditionally provided shared nursing spaces. Due to the spread of COVID-19, many types of simple indoor nursing booths have been developed for installation within buildings. There is a growing need for a single booth that can accommodate not only office work and meetings, but also breastfeeding and diaper changing.

[0004] Small panels used in furniture and other items are joined together using a variety of methods. For example, two panels are joined together by drilling dowel holes on the opposing surfaces and fitting slightly thicker dowel shafts into both holes. Alternatively, a shaft with an enlarged head protrudes from one panel, and a clamping disk with a forked locking portion is embedded in the other panel. The enlarged head is positioned on the arcuate track of the clamping disk, and then the clamping disk is rotated to hook the enlarged head onto the forked locking portion, drawing the enlarged head to the center of the clamping disk and tightening it to join the panels together. Alternatively, the panels are joined together using screws.

[0005] However, when attempting to integrate the large wall panels that make up the indoor installation room using conventional integration methods, there was a risk that the joints would not be strong enough, and increasing the number of joints would increase the effort and cost required to integrate them.

[0006] Patent Document 1 discloses a technology for a connecting structure of wall panels equipped with tubular frames on both sides. According to the technology described in Patent Document 1, tubular frames are provided on the sides of two wall panels to be connected, and vertically elongated holes of the same shape, with a wide upper portion and a narrow lower portion, are drilled at opposing positions on each tubular frame.

[0007] An elongated member with an L-shaped cross section is then inserted into one of the cylindrical frames along the cylindrical frame with its upper portion protruding from the other cylindrical frame. The screw with an enlarged head is then fixed to the elongated member so that its enlarged head passes through the wide portion of the vertically elongated hole and protrudes onto the opposing surface of the cylindrical frame.

[0008] Then, the enlarged head of one of the cylindrical frames is fitted into the wide hole of the other cylindrical frame, and with the two cylindrical frames close together, the long member protruding upward from one of the cylindrical frames is dropped downward. This causes the edges of the narrow holes in the two cylindrical frames to be clamped between the enlarged head of the screw with the enlarged head and the long member, thereby tightening the opposing surfaces of the two cylindrical frames.

[0009] This technique requires cylindrical frames on both side edges of the wall panel, and the top of the cylindrical frames must be open in order to drop the long members into the cylindrical frames, which poses the problem that it cannot be applied to wall panel structures in which the wall panel bodies are assembled by touching them together.

[0010] Patent Document 2 discloses a technology for a connecting device that connects low partitions by moving them vertically. According to the technology described in Patent Document 2, an engaging claw is provided on one of the contact surfaces of the end cover and corner post that make up the low partition, and an engaging hole is provided on the other, and the two components are connected by fitting the engaging claw into the engaging hole and moving it vertically.

[0011] According to this technology, four engagement claws are provided at the upper position and four at the lower position, and after they are fitted together, a lock pin is activated to horizontally engage the two components, preventing the two panels from sliding up and down. According to this technology, both the engagement claws and engagement holes are provided in metal corner posts or end covers. However, because the engagement claws are plate-shaped members and the engagement holes are narrow slits, there was a problem in that it was time-consuming to align and engage the multiple engagement claws with the engagement holes.

[0012] According to the wall panel structure to which the technology described in Patent Document 1 or Patent Document 2 is applied, it is possible to assemble large wall panels that form an indoor installation booth with high strength. However, there is a problem in that it is necessary to attach a cylindrical frame or the like to the contact surface between the two panels, and it cannot be applied to a connecting structure that directly connects the wall panel bodies.

[Means for solving the problem]

[0015] The first invention of the present invention is a wall panel structure for an indoor installation room made up of a plurality of wall panels, the wall panel structure having a plurality of connecting means at upper and lower positions where two wall panels face each other, each of the connecting means comprising a pair of an embedded portion and a receiving portion, the embedded portion having a leg portion, a support plate portion and a fitting portion, the leg portion being embedded in a hole drilled in an end portion of one of the wall panels at the facing position, the support plate portion extending forward from the leg portion and having a narrow shape, the fitting portion having a smoothly narrowed forward corner and protruding forward of the support plate portion, the receiving portion having an open groove portion and and a slit portion that is carved into the end of the other wall panel at the opposing position, the open groove portion having an open groove of a width that allows the fitting portion to be inserted, the slit portion being located below the open groove portion and having a gap width that is wider than the support plate portion and narrower than the fitting portion, the fitting portion being inserted from the front corner portion into the open groove and then dropped along the open groove portion, the support plate portion being sandwiched between the slit portion and the embedded portion being stored in the receiving portion, and the two wall panels being connected at upper and lower positions by the plurality of connecting means.

[0016] According to the first aspect of the present invention, the support plate portion forming the embedded portion extends in a narrow shape from the leg portion embedded in the wall panel toward the front, forming a vertically long support plate portion, and the front corner of the fitting portion protruding toward the front of the support plate portion is smoothly tapered. In addition, the two wall panels are connected at the top and bottom by connecting means.

[0017] According to the first aspect of the present invention, the forward corner of the fitting portion forming the embedded portion is smoothly tapered, so that the embedded portion protruding from one wall panel can be easily inserted into the open groove portion forming the receiving portion of the other panel and dropped into the slit portion. Furthermore, the two wall panels are firmly connected at the top and bottom positions by the vertically elongated connecting means. This allows multiple wall panels to be easily and firmly connected to form an indoor installation room.

[0018] The second invention of the present invention is characterized in that, in the wall panel structure of the first invention, an upper frame member is further included, and the plurality of wall panels are connected in order from the wall panel having the receiving portion among adjacent wall panels, and the upper frame member is fixed to the upper parts of the plurality of wall panels with metal fittings, so that the plurality of wall panels are movably integrated.

[0019] According to the second aspect of the present invention, multiple wall panels are connected in order, and the upper part of the assembled wall panels is fixed with a top frame and metal fittings, so that the multiple wall panels are integrated so that they cannot be easily separated. This makes it easy to lift and move the integrated indoor installation room. [Effects of the Invention]

[0020] According to the first aspect of the present invention, a plurality of wall panels can be easily and firmly connected to form an indoor installation room. According to the second aspect of the present invention, the integrated indoor installation chamber can be easily lifted and moved. [Brief explanation of the drawings]

[Figure 5] An explanatory diagram of the configuration of the folding door hanging position (Example 1). [Figure 6] FIG. 1 is a side view of the entrance side of the nursing room (Example 1). DETAILED DESCRIPTION OF THE INVENTION

[0022] In order to make it easy to assemble the nursing room within the building, it is constructed from wall panels having connecting means, the entrance is a folding door that does not require a lower rail, strollers can enter the room without going over a step, and the nursing room is provided with storage spaces that can store strollers in two intersecting horizontal directions, and a nursing space. [Example]

[0023] In Example 1, a nursing room 1 will be described with reference to Figures 1 to 6. Figure 1 shows a perspective view of the nursing room, and Figure 2 shows a front view of the nursing room 1. Figure 3 shows an explanatory diagram of the nursing room 1 in use, using a cross-sectional view taken along line AA in Figure 2.

[0024] Figure 4 shows a perspective view of the configuration of the wall panel connecting means at position C in Figure 3. Figure 5 is an explanatory diagram showing the configuration of the folding door hanging position as viewed from inside the nursing room. Figure 6 is a side view of the entrance / exit side of the nursing room as viewed from inside the nursing room. In the following examples, the side with the entrance / exit will be referred to as the front, the left side as viewed from outside the nursing room toward the front as the left side, the right side as viewed toward the front as the right side, and the side opposite the front as the back.

[0025] Nursing room 1 is assembled by connecting wall panels consisting of wall board 10 and narrow wall board 11 with connecting means 100. Nursing room 1 is designed to accommodate a stroller 2 (see Figure 3) carrying an infant, and so to prevent the nursing room from moving easily even if stroller 2 hits the wall panel, only height adjustment adjusters 12 are provided below the wall panel, and no casters are provided for movement. To make it easy to move and fold stroller 2, the floor of the building in which it is installed is used as the floor of nursing room 1 (see Figure 2).

[0026] The entrance 20 to the nursing room 1 is sandwiched between a left wall panel 10 and a narrow wall panel 11 that are perpendicular to the entrance direction, and the folding door 30 located on the left side of the front is arranged on the same plane as the narrow wall panel 11 (see Figure 1). The folding door 30 is divided into a 1 / 3 width section 31 and a 2 / 3 width section 32 of the folding door width, and the left end of the 1 / 3 width section is pivoted to a fixed hanging point 33 (see Figure 2) at the left end of the entrance 20.

[0027] The center position of the 2 / 3 width section 32 is the front hanging section 34, which slides along the folding door rail 40 (see Figure 5) as the folding door is folded open or closed. The lower part of the fixed hanging side of the 1 / 3 width section 31 of the folding door 30 is pivotally supported by an L-shaped fixing bracket 35 fixed to the end of the wall panel perpendicular to the direction of the entrance / exit 20. Since the folding door 30 is suspended only by the folding door rail 40, excluding the pivotal support part below the fixed hanging side, a lower rail is not required, and wheels for sliding the folding door are also not required.

[0028] Vertically extending opening / closing handles 36 are provided on the inside and outside of the folding door 30 at the center of the height of the front end of the door. When entering the room, the outside opening / closing handle 36 is grasped and slid to the left, opening the folding door 30 so that the folding part of the folding door 30 faces the room, thereby opening the entrance / exit 20 (see Figure 3). After the caregiver enters the nursing room through the entrance / exit with the stroller 2, they grasp the inside opening / closing handle 36 and slide it to the right to close the folding door 30, thereby closing the entrance / exit.

[0029] Three milky white circular windows 37 are provided above the center of the folding door, hiding the interior from view from the outside while allowing the occupancy status of the nursing room to be seen from the outside. Additionally, an upper lock 38 and a lower lock 39 are provided on the interior side of the folding door 30, one above the other (see Figure 6). Both the upper lock 38 and the lower lock 39 are latches that are locked when a locking hook catches on the locking shaft.

[0030] The lower lock 39 is an indicator lock that allows the lock status to be seen from the outside, and when it is locked from the inside it displays red, and when it is not locked from the inside it displays blue. Also, even if the lower lock is locked from the inside, it is an emergency lock that can be unlocked in an emergency by inserting a key into the keyhole and twisting it, which will rotate the latch and unlock the lock.

[0031] The upper lock 38 is a latch lock that can be operated only from the inside to lock the door open or closed. The upper lock 38 is installed at a height of at least 3 / 4 of the height of the folding door, out of the reach of infants, so that when a guardian is in the nursing room with an infant, the infant cannot unlock the lock and leave by themselves (see Figure 6). Because the infant will not leave alone, the guardian can breastfeed, change diapers, etc. with peace of mind.

[0032] The spatial configuration of the nursing room will now be described with reference to Figure 3. Figure 3 shows a cross-sectional view taken along the line A-A in Figure 2. In nursing room 1, a preparation table 50 is installed in a wall position desired by the installer. This nursing room is made of a combination of wall panels based on wood or other materials and thin wall panels, so the preparation table 50 can be installed in a position desired by the installer by nailing or the like. Of course, a diaper changing bed 51, a nursing sofa 52, lighting equipment, emergency call equipment, emergency detection equipment using a motion sensor, etc. may also be installed in desired positions.

[0033] The nursing room has a space 53 for storing a stroller at the position where you enter after opening the doorway. With stroller 2 coming straight into the room through the doorway, you can use preparation table 50 to prepare for breastfeeding or changing a diaper, then change the baby's diaper on diaper changing bed 51 and breastfeed the baby on nursing sofa 52. If you are bringing an infant, you can first have the infant enter storage space 53, store the stroller sideways on the doorway side of the storage space, and then prepare to breastfeed after the infant is inside the room.

[0034] By folding the stroller 2, the storage space 53 of the stroller 2 can be made larger, and after locking the upper lock 38, the infant can relax, while the parent or guardian can prepare to breastfeed in the spacious storage space 53. In Figure 3, a diaper changing bed 51 and a nursing sofa 52 are installed in the nursing space 54, but the installer may install any furniture and fixtures he or she desires.

[0035] Referring to Figure 4, the connecting means 100 for assembling the wall panels will be described. Figure 4 shows the connecting means 100 provided at the joint surface between the wall panels 10 at the position surrounded by C in Figure 3. The connecting means 100 is not limited to this position, and can be provided in multiple stages in the vertical direction not only at position C where the end face of one wall panel 10 faces the end face of another wall panel 10, but also at position B where the wall panel surface faces the end face of another wall panel. At the back of the nursing room 1, two wall panels 10 are connected to form the back wall panel.

[0036] A plurality of sets of connecting means 100 are provided above and below the two wall panels 10, 10 where they face each other. One of the connecting means is a fitting portion 110, and the other is a receiving portion 120. The fitting portion 110 is an integrated connecting tool consisting of a support plate portion 111, a fitting portion 112, and legs 113.

[0037] The fitting portion 110 is formed by embedding the leg portion 113 of the connecting means into a hole drilled at the end of the wall panel 10, with a narrow support plate portion 111 forming the base at the tip of the leg portion 113, and fitting portions 112 with smoothly narrowed corners at the tip of the base protruding from the end of the wall panel 10.

[0038] The receiving portion 120 is formed by carving an open groove 121 and a slit 122 into the end of the wall panel 10. The open groove 121 is positioned toward the fitting portion 110 with its open end facing the fitting portion 110, and the slit 122 is formed below the open groove 121. The open width of the open groove 121 is wider than the width of the fitting portion 112 of the fitting portion. The gap width of the slit 122 is narrower than the fitting portion 112 and wider than the support plate portion 111, and the gap depth of the slit 122 is formed to be the same as the protruding height of the support plate portion 111.

[0039] The front end of the fitting portion 112, which has a narrowed shape at the front, is inserted into the open groove portion 121, and the fitting portion 112 is slid down along the groove of the open groove portion 121 (see the white arrow in Figure 5), whereby the support plate portion 111 located at the base of the fitting portion 112 is stored while being sandwiched between the slit portion 122, and the two wall panels 10, 10 are connected.

[0040] Adjacent wall panels 10, 10 are assembled with the heights of the tops of the wall panels aligned, with the fitting portion 110 forming the connecting means higher than the receiving portion 120 so that the fitting portion 112 is at the same height as the slit portion 122. Adjacent wall panels 10, 10 are provided with connecting means 100 in at least two locations, one above the other, facing each other.

[0041] First, the joining surfaces of the two wall panels 10, 10 are placed parallel to each other, and the wall panel 10 equipped with the fitting portion 110 is made higher than the wall panel 10 equipped with the receiving portion 120 by the height of the fitting portion 112. The fitting portion 112 is then inserted from the side into the open groove portion 121, and the fitting portion 112 is dropped from the open groove portion 121 into the slit portion 122 to connect the adjacent wall panels.

[0042] When assembling the wall panels of nursing room 1, it is preferable to connect the wall panels starting from one side, in order, starting with the wall panels having receiving section 120, for example, connecting right-side wall panel 10 to narrow wall panel 11, connecting the rear wall panel to the right-side wall panel, etc. Once all wall panels 10 and narrow wall panels 11 are assembled together, it is recommended to adjust the height of height adjustment adjusters 12 provided below each wall panel to adjust the verticality of each wall panel and the verticality of the entire nursing room.

[0043] Then, the louver receiving frame 41 of the ceiling louvers is fixed to the top of the connected wall panels 11, 10, 10, ... with screws or the like so that adjacent wall panels 11, 10, 10, ... do not shift up and down, and the surrounding wall panels are tightly fastened together. Because all of the wall panels are tightly fastened together, it is easy to lift the nursing room 1 and move it to the desired installation location.

[0044] With the front narrow wall panel 11, the right wall panel 10, the back wall panels 10, 10, and the left wall panel 10 tightly fastened together, an upper frame 42 connecting the left and right wall panels 10 is fixed to the inside upper part of the narrow wall panel 11 with screws or the like. Because the upper frame 42 extends along the back of the narrow wall panel 11, even if only the upper frame 42 connects the left and right wall panels 10, 10 above the doorway 20, the wall panels of the nursing room 1 cannot be easily separated.

[0045] The rail frame 43 with the folding door rail 40 stored in it is fixed with screws or the like so that it is in contact with the outside of the upper frame 42, and the outer surface of the rail frame 43 is flush with the outer surface of the narrow wall panel 11. The head of the hanging shaft located at the left end of the 1 / 3 width section 31 of the folding door 30 and the head of the hanging shaft in the center of the 2 / 3 width section are hung on the C-shaped folding door rail 40, which is open at the bottom. Then, the hanging shaft on the hanging side of the 1 / 3 width section 31 is used as the fixed shaft, and the lower end of the 1 / 3 width section 31 is supported by the hanging bracket 35, and the folding door 30 is attached to the wall structure of the nursing room 1.

[0046] Because the folding door 30 does not require a lower rail, there is no need to overcome a step when pushing the stroller 2 through the entrance 20, and sleeping babies will not be woken up by vibrations. Also, parents using wheelchairs can enter the nursing room 1 and breastfeed their babies.

[0047] Locks are attached to the folding door 30 at the positions of the upper lock 38 and the lower lock 39 so that the locking shaft and locking hook correspond to each other. The folding door is slid while the front hanging part 34 (see Figure 3) in the center of the 2 / 3 width part 32 is supported by the folding door rail 40, and when the doorway is open, the front 1 / 3 of the width of the 2 / 3 width part 32 is outside the nursing room, and the 1 / 3 of the width of the folding door from the hanging shaft is inside the nursing room. For example, if the folding door width is 1.2 m, the folding door will only protrude 40 cm into and out of the room, making it unlikely to obstruct the passage and movement of people inside and outside the nursing room 1.

[0048] Furthermore, lattice louvers 60 are placed on the upper frame at the front and on the tops of the right, left, and rear wall panels. Upper frame 42 is a ribbed member with a wide rectangular cross section, with the upper part on the interior side carved out to serve as a lattice louver support, so that the front part of the nursing room where the entrance and exit will be installed will be strong. Louver support frame 41 is fixed to the upper part of the right, rear, and left wall panel with screws or the like, and is a ribbed member with a narrow rectangular cross section, with the upper part on the interior side carved out to serve as a lattice louver support, so that it only needs to secure the wall panels 11, 10, 10, ... and prevent them from shifting up and down and becoming separated.

[0049] The lattice louvers 60 are removably placed on the upper frame 42 at the front and the louver receiving frames 41 on the other three sides. In the nursing room 1, two auxiliary louver receiving frames 44, 44 are provided from the upper frame toward the louver receiving frame 41 at the back (see Figure 1), dividing the ceiling surface into three rows on which the lattice louvers 60, 60, 60 can be placed. Because the lattice louvers 60 are simply placed on the louver receiving frames 41 or the auxiliary louver receiving frames 44, the lattice louvers 60 can be easily removed from the top of the nursing room.

[0050] The upper lock 38 is provided at a height of ¾ or more of the height of the folding door 30, so that in an emergency, to unlock the upper lock 38, a person standing on a stepladder can lift the entrance side of the lattice louvers 60 in the center row and look into the nursing room, thereby unlocking the upper lock 38 from inside the nursing room.

[0051] The lattice louvers 60 are made of approximately 4cm wide resin strips that are assembled vertically and horizontally across the entire ceiling surface to form a grid of approximately 3cm. The light from the ceiling lighting in the room where the nursing room is installed is diffused by the vertically and horizontally arranged strips that make up the lattice louvers, brightening the nursing room and creating a soft, calming lighting environment inside the nursing room, allowing parents to nurse in a relaxed atmosphere.

[0052] In the space shown in Figure 3, the concentration and temperature of nursing milk can be adjusted on a preparation table 50 (see Figure 3), replacement disposable diapers and other items can be prepared, diaper changes can be performed on a diaper changing bed 51, and nursing can be performed on a nursing sofa 52. Of course, a motion sensor can be installed in the nursing room, and if an emergency is anticipated, an emergency notification can be sent when the motion sensor detects no human movement.

[0053] (others) In Example 1, by reversing the assembly procedure, the ceiling louvers 60, the folding door 30, the upper frame 42, the louver receiving frame 41, and the wall panels with the fitting portions 110 are sequentially lifted and removed, and the wall panels are separated in order. This allows the parts to be separated into parts that can be transported within the building, and can be easily moved to another location. The connecting means 100 shown in the first embodiment is not limited to nursing rooms, and can of course be applied to indoor installation booths for assembling wall panels for other purposes. Furthermore, the vertical fixation of the wall panels connected by the connecting means is not limited to the louver receiving frame, and any wall panel fixing device such as a plate, shaft member, or surface member attached across adjacent connected wall panels can be used. The embodiments disclosed herein are illustrative in all respects and should not be considered limiting. The technical scope of the present invention is not limited to the above description, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.
