Description

Technical Field

[0001] The present invention relates to the technical field of partition devices provided for partitioning the interior of buildings such as buildings.

Background Art

[0002] Generally, partition devices using panel bodies are provided for partitioning the interior of buildings such as buildings. Among such partition devices, there are those in which the panel body is made into a hinged door type that can open and close in the front-back direction and those in which the panel body is made into a sliding type (sliding door type) that can slide in the left-right direction, and they may be used in combination (see, for example, Patent Document 1). In such a partition device that combines a hinged door type and a sliding door type panel body, when the panel body is of the sliding type, a traveling roller (door wheel) provided at the lower edge of the sliding type panel body is made to travel on a traveling rail provided on the floor surface side so that it can slide in the left-right direction. In this case, there is a problem that the concave fitting of the traveling roller to the traveling rail may be shallow, and when a large load acts in the front-back direction due to an object or a person hitting the sliding type panel body, there is a risk that the traveling roller may come off the traveling rail. Therefore, in order to prevent the traveling roller from coming off the traveling rail, there is a known one in which a retaining member is provided on the traveling roller (see, for example, Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the conventional method of providing a retaining material to a running roller, the retaining material is detachably attached to the frame material on which the running roller's wheels are mounted. This results in a complex structure for the running roller, including the frame material, making it impossible to use a general-purpose running roller that can be used in general. These are the problems that the present invention aims to solve. [Means for solving the problem]

[0005] The present invention was created in view of the above circumstances and with the aim of solving these problems, and the invention of claim 1 is a partition device in which, among a plurality of panel bodies that divide an interior space front to back, at least one panel body is a hinged door type panel body that can be opened and closed in the front to back direction, and the panel body adjacent to the door side of the hinged door type panel body is configured as a sliding panel body in which a running roller provided on the lower edge of the panel body moves in the left to right direction on a running rail provided on the floor surface, wherein the sliding panel body is provided with a retaining material that has a retaining groove that fits onto the running rail to prevent the running roller from coming off the running rail, and the retaining material is attached to the lower ends of the left and right vertical frame members arranged on both the left and right edges of the panel body. The invention of claim 2 is a partition device according to claim 1, characterized in that the vertical frame material is a vertical frame material provided on the left and right edges of a sliding panel body, or a meeting material provided on the vertical frame material. The invention of claim 3 is a partition device according to claim 1 or 2, characterized in that the traveling roller comprises a support frame member that pivotally supports the roller body, a frame member that is attached to a sliding panel body in a state in which the support frame member is fitted inside, and a height adjustment means for adjusting the height of the roller body relative to the frame member by moving the support frame member relative to the frame member in the left-right direction, the height adjustment means is provided with an adjustment tool for adjusting the height of the roller body by a tool that is passed through a through hole provided in the leading piece of the vertical frame member, and the retaining member is attached via screws below the through hole portion of the leading piece of the vertical frame member. The invention of claim 4 is a partition device according to claim 3, characterized in that the retaining member is attached to the vertical frame member so as to be vertically adjustable in position. The invention of claim 5 is a partition device according to claim 1, characterized in that the retaining member is provided on the vertical frame member and is arranged with a gap remaining on the left and right outward relative to the running roller. The invention of claim 6 is a partition device according to claim 1, characterized in that the sliding panel body has a guide body provided on its upper edge that fits into a U-shaped guide rail provided on the ceiling rail to guide the movement of the upper edge, and the upper edge of the sliding panel body is provided with an upward movement restricting member that is positioned in close proximity to and opposite to either the front or rear rail piece of the guide rail to restrict the upward movement of the sliding panel body. [Effects of the Invention]

[0006] By adopting the invention of claim 1, when the partition device is configured such that the panel body adjacent to the door-side of the hinged door type panel body is a sliding panel body in which a running roller provided on the lower edge of the panel body moves left and right along a running rail provided on the floor surface, the retaining material for preventing the running roller from coming off the running rail is attached to the lower ends of the left and right vertical frame members provided on both the left and right edges of the panel body. As a result, the retaining material can be attached without using a special running roller to which it is attached, and the vertical frame members provided on the sliding panel body can be effectively utilized, thereby simplifying the structure. By adopting the invention of claim 2, the vertical frame member to which the retaining material is attached becomes a vertical frame member provided at the left and right edges of the sliding panel body, or a meeting member provided on said vertical frame member, thereby simplifying the structure. By adopting the invention of claim 3, the running roller is provided with a height adjustment means that allows the height of the roller body to be adjusted, and the height adjustment operation of the roller body can be performed by a tool that is inserted through a through hole provided in the leading piece of the vertical frame material. As a result of attaching the retaining member to the leading piece of the vertical frame material in which the through hole for the tool is formed via a screw, the leading piece in which the through hole is formed also serves as a member for attaching the retaining member, thereby further simplifying the structure. As a result of the invention of claim 4, the retaining material is attached to the vertical frame material so as to be vertically adjustable, the retaining of the running roller by the retaining material can be adjusted according to the installation state of each sliding panel body, thereby improving convenience. By adopting the invention of claim 5, the anti-detachment member is provided on the vertical frame member that is detached from the running roller portion, and is positioned with a gap to the left and right outward relative to the running roller. As a result, when a load is applied that causes the running roller to detach from the running rail, the anti-detachment member positioned with a gap from the running roller portion will receive this load, thereby achieving a higher anti-detachment effect. By implementing the invention of claim 6, the guide body provided on the upper edge of the sliding panel body is fitted into the guide rail on the ceiling side to guide the movement of the upper edge. The upward movement restricting member provided on the sliding panel body is positioned in close proximity to one rail piece of the guide rail to restrict the upward movement of the sliding panel body, thereby assisting in preventing the running roller from coming off the running rail. As a result, a better anti-detachment function for the running roller is achieved. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0008] The embodiments of the present invention will now be described based on the drawings. In the drawings, 1 is a partition device (partition) installed to divide the interior of a building such as an office building from front to back, and the partition device 1 is composed of a plurality of panel bodies 2 and 3 that are arranged continuously in the left-right direction to divide the space between the left and right walls W from front to back. In this embodiment, the partition device 1 is used to conveniently divide a workspace (office) X where people work (work) and a storage room Y where various equipment and furnishings such as air conditioning units are housed, and the partition device 1 will be described as using three panel bodies 2 and 3. In describing this embodiment, the work chamber X side is defined as the front and the storage chamber Y side as the rear, and the front-to-back direction is described accordingly. However, this definition of the front-to-back direction is for convenience only, and it goes without saying that the present invention is not to be interpreted in a way that is strictly bound by this definition.

[0009] Among these panel bodies 2 and 3, the panel body 2 on one end side in the left - right direction constitutes an opening door - type panel body 2 which is hinged so that the edge part on the door - bottom side can be opened and closed forward by a hinge 2a. The remaining two panel bodies 3 constitute slide - type panel bodies 3 which can slide in the left - right direction in a state where the opening door - type panel body 2 is opened. Needless to say, as the panel body, a fixed - type one that is not opened and closed when necessary may also be used.

[0010] The slide - type panel body 3 is configured with a four - sided frame, with vertical frame members 4 provided at both left and right edge parts and horizontal frame members 5 and 6 facing in the horizontal direction provided at both upper and lower edge parts. Among the left and right vertical frame members 4, a mating member 7 is attached to the vertical frame member 4 on the side of the opening door - type panel body 2 (left side in the drawing), while the vertical frame member 4 on the side opposite to the opening door - type panel body 2 is a single one without the attachment of the mating member 7. By configuring like this, on the side of the opening door - type panel body 2, the mating member 7 constitutes the "vertical frame member" of the present invention, and on the side opposite to the opening door - type panel body, the vertical frame member 4 constitutes the "vertical frame member" of the present invention. Incidentally, the mating member 7 is configured to mate in a state of overlapping (coinciding) in the front - rear direction with the vertical frame members 4 provided at the edge parts of the adjacent panel bodies 2 and 3 when the partitioning device 1 is closed.

[0011] On the lower frame member 6, left and right running rollers (door wheels) 8 are provided with a gap in the inner side in the left - right direction with respect to the vertical frame member 4. The roller bodies (wheels) 8a provided on the running rollers 8 run on a running rail (guide rail) 9 provided on the floor surface F side, so that the slide - type panel body 3 is configured to be able to slide in the left - right direction. In this case, the running rail 9 is provided on the upper part 10a of a crosspiece 10 having a U - shaped cross - section. The crosspiece 10 is externally fitted to a floor rail 11 whose bottom plate part 11a is fixed to the floor surface F via screws 11b, and the height from the floor surface F is adjusted by a height adjuster 12 provided between the upper part 10a of the crosspiece 10 and the bottom plate part 11a of the floor rail 11.

[0012] On one side, on the finding surface 5a on the accommodation chamber Y side of the upper frame member 5, a guide body 13 is attached via a bracket 13a corresponding to the portion where the traveling roller 8 is provided, and the guide body 13 is fitted in a U-shaped guide rail 16 provided on a base frame 15 attached to the ceiling surface H via a ceiling rail 14 so as to be movable in the left - right direction. And in the slide - type panel body 3 configured in this way, with the guide body 13 on the upper edge portion side being guided left - right by the guide rail 16 and the traveling roller 8 on the lower edge portion side being guided for traveling by the traveling rail 9, it is configured to be able to slide - move in the left - right direction. In the slide - type panel body 3 configured in this way, an upward movement restricting member 17 that can be adjusted in the up - down direction by screwing into the bracket 13a is provided. The upward movement restricting member 17 is adjusted to be close - opposed from below to the rail piece 16a on the outer side in the front - rear direction of the guide rail 16. As a result, the upward movement of the slide - type panel body 3 is restricted, and it is configured to prevent the traveling roller 8 from coming off the traveling rail 9.

[0013] The traveling roller 8 includes a support frame member 8b that pivotally supports a roller body 8a rotatably, and a frame frame member 8c that is externally fitted and incorporated with the support frame member 8b. The frame frame member 8c is attached and fixed to a lower frame member 6 provided on the slide - type panel body 3 via screws 8d. And the roller shaft 8e that pivotally supports the roller body 8a of the traveling roller 8 attached in this way is movably supported by a frame - side guide hole 8ba facing the up - down direction provided in the support frame member 8b, and is also movably supported by a guide hole 8ca for the roller body provided in the frame frame member 8c and inclined so that the outer side in the left - right direction is higher.

[0014] On the other hand, the support frame member 8b has a movable shaft 8bb provided at an inner portion in the left - right direction pivotally supported movably in the left - right direction with respect to a guide hole 8cb for the frame member facing the left - right direction provided in the frame frame member 8c. Furthermore, a rod-shaped adjustment tool 8g for height adjustment is supported on the left-right outer projection piece 8f of the frame material 8c so as to be rotatable around its axis, with its movement restricted in the left-right direction. This adjustment tool 8g is screwed into the left-right outer projection piece 8bc of the support frame material 8b. Then, by inserting the tool Z into the operating head 8ga which is exposed (protrudes) outward in the left-right direction from the visible piece 8f of the frame material 8c of the adjustment tool 8g and rotating the adjustment tool 8g around its axis, the support frame material 8b moves relative to the frame material 8c in the left-right direction. As the support frame material 8b moves relative to the support frame material 8b, the roller shaft 8e is guided by the frame material side guide hole 8ba and moves relative to the support frame material 8b in the vertical direction, while being guided by the roller body guide hole 8ca relative to the frame material 8c and moves relative to the vertical inclination direction. This allows the height of the roller shaft 8e to be adjusted, thus constituting the height adjustment means of the present invention. Furthermore, the running roller 8 can also be implemented in which the movable shaft 8bb is provided on the frame member 8c side instead of the support frame member 8b side, and the guide hole 8cb for the frame member is provided on the support frame member 8b side instead of the frame member 8c side.

[0015] The vertical frame member 4 is integrally provided with the sliding panel body 3 during its manufacture. It comprises inner and outer projection pieces 4a and 4b in the left-right direction, and front and rear projection pieces 4c and 4d. The front and rear projection pieces 4c and 4d are formed by bending from the front and rear edges of the inner projection piece 4a, and the outer projection piece 4b is formed by bending from the front edge of the rear projection piece 4d. The front projection piece 4c is longer than the rear projection piece 4d, and the outer projection piece 4b is shorter, reaching only to the middle of the front projection piece 4c. The vertical frame member 4, configured in this manner, has a notched lower edge 4ba of the outer projection piece 4b. The lower edge 4aa of the inner projection piece 4a, visible through the notched lower edge 4ba of the outer projection piece 4b, has a through hole 4e formed therein for inserting a tool Z through the operating head 8ga provided on the height adjustment means. A screw hole 4f is also formed below the through hole 4e for attaching a retaining member 18, which will be described later.

[0016] In contrast, the meeting stile 7 is composed of inner and outer projection pieces 7a and 7b in the left-right direction, and front and rear facing pieces 7c and 7d on both sides. The inner projection piece 7a is attached to the outer projection piece 4b of the door-side vertical frame member 4 via screws 7e. The front facing piece 7c, which bends from the front edge of the inner projection piece 7a, is set to overlap the front facing piece 4c of the door-side vertical frame member 4 provided on the adjacent panel body 2 or 3 in the front and rear directions. The outer projection piece 7b, which bends from the tip edge of the front facing piece 7c, is in close proximity to the outer projection piece 4b of the vertical frame member 4 provided on the adjacent panel body 2 or 3. The rear facing piece 7d, which bends from the tip edge of the outer projection piece 7b, is short and does not reach the inner projection piece 7a. As described above, the meeting stile 7 is configured such that the inner projection piece 7a is attached to the outer projection piece 4b of the door-side vertical frame member 4. In this attached state, the front projection piece 7c is long enough to reach the lower edge of the sliding panel body 3, and is configured to close the gap between the opposing front projection pieces 4c of the vertical frame members 4 provided on adjacent panel bodies 2, 3 or 3, 3.

[0017] On the other hand, the outer facing portion 7b and the rear facing portion 7d are shorter than the operating head 8ga, and the inner facing portion 7a is the length between the outer facing portion 7b and the front facing portion 7c. The lower end edge 7aa of the inner facing portion 7a, which is visible below the lower end edge 7ba of the outer facing portion 7b, has a through hole 7f formed therein for inserting the tool Z into the operating head 8ga, and a screw hole 7g is formed below the through hole 7f for attaching the retaining material 18, which will be described later. Incidentally, the through-hole 7f is positioned at the same location as the through-hole 4e provided in the outer projection piece 4b of the vertical frame member 4 to which the meeting piece 7 is attached. This configuration allows the tool Z to be inserted through the through-holes 7f and 4e on the side to which the meeting piece 7 is attached, enabling the rotational operation of the operating head 8ga.

[0018] In the partition device 1 configured in this manner, the sliding panel body 3 can be slid left and right while the hinged door-type panel body 2 is open. However, the roller body 8a, which is provided on the running roller 8 that guides the running of the sliding panel body 3, has a shallow engagement depth with the running rail 9, and there is a risk of it coming off. To avoid this, the aforementioned anti-detachment member 18 is provided. The anti-detachment member 18 is in the shape of a rectangular plate, with a U-shaped (inverted U-shaped) anti-detachment groove 18a formed on its lower edge, and a vertically elongated screw hole 18b is formed above the anti-detachment groove 18a. The retaining material 18 is then attached to the sliding panel body 3. If the meeting stile 7 is not attached to the vertical frame member 4, the retaining material 18 is attached to the vertical frame member 4. If the meeting stile 7 is attached, the retaining material 18 is attached to the meeting stile 7.

[0019] First, to attach the retaining member 18 to the vertical frame member 4, the retaining member 18 is positioned so that the retaining groove 18a is fitted onto the running rail 9, and the screw holes 4f and 18b are facing each other, and the screw 18c is screwed into the screw holes 4f and 18b from the left and right outer side. In this case, the depth to which the retaining groove 18a is fitted onto the running rail 9 is adjusted by shifting the position of the elongated screw hole 18b up and down.

[0020] Similarly, when attaching the retaining material 18 to the meeting piece 7, with the retaining groove 18a fitted onto the running rail 9, the retaining material 7 is attached by bringing the screw holes 7g and 18b facing each other against the lower edge 7aa of the inner projection piece 7a of the meeting piece 7 from the left-right outward side, and then screwing the screw 18c into the screw holes 7g and 18b. In this case as well, the depth to which the retaining groove 18a is fitted onto the running rail 9 is adjusted by shifting the position of the elongated screw hole 18b up and down.

[0021] In this embodiment configured as described above, the partition device 1 is configured such that the panel body adjacent to the door end of the hinged door type panel body 2 is a sliding panel body 3. When the sliding panel body 3 is configured such that a running roller 8 provided at its lower edge travels along a running rail 9 provided on the floor side, and a retaining member 18 is provided to prevent the running roller 8 from coming off the running rail 9, the retaining member 18 is attached to the vertical frame members 4 and meeting members 7, which are vertical frame members at both the left and right edges of the sliding panel body 3. As a result, the structure can be simplified by effectively utilizing the vertical frame members 4 and meeting members 7 provided as members at both ends of the sliding panel body 3, without using a special running roller to which the retaining member is attached, as in the conventional method.

[0022] In this case, the running roller 8 provided on the sliding panel body 3 is equipped with a height adjustment means for adjusting the height of the roller body 8a, and the adjustment operation of the operating head 8ga of the adjustment tool 8g for adjusting the height of the height adjustment means can be performed by a tool Z that penetrates through through holes 4e and 7f provided in the inner visible pieces 4a and 7a of the vertical frame member 4 and meeting member 7. As a result of attaching the retaining material 18 to the inner visible pieces 4a and 7a of the vertical frame member 4 and meeting member 7, the inner visible pieces 4a and 7a are also used as members for attaching the retaining material 18, thereby simplifying the structure, and a general-purpose running roller 8 can be used instead of a special one for attaching the retaining material 18.

[0023] Furthermore, since the attached retaining material 18 is mounted to the vertical frame material 4 and meeting material 7 in a position that can be adjusted vertically, the retaining function of the retaining material 18 on the running roller 8 can be adjusted according to the installation state of each sliding panel body 3, thereby improving convenience. Furthermore, the anti-detachment members 18 are provided on the vertical frame members 4 and meeting members 7 that are spaced outward in the left-right direction from the running rollers 8. As a result, when a load is applied to the sliding panel body 3 that causes the running rollers 8 to detach from the running rails 9, the anti-detachment members 18, which are positioned outward in the left-right direction with a gap from the running rollers 8, will receive this load, thereby providing a higher anti-detachment effect.

[0024] Furthermore, in the implementation of the present invention, the sliding panel body 3 has a guide body 13 provided on its upper edge that fits into the guide rail 16, providing guidance for its upper edge. The upward movement restricting member 17 provided on the sliding panel body 3 is positioned close to and opposite one of the rail pieces 16a of the guide rail 16, thereby restricting the upward movement of the sliding panel body 3. As a result, this enhances the effect of preventing the running roller 8 from coming off the running rail 9, allowing the running roller 8 to exhibit a superior anti-detachment function. [Industrial applicability]

[0025] This invention can be used as a partitioning device installed to divide the interior of a building, such as an office building. [Explanation of symbols]
