Description

Technical Field

[0001] Embodiments of the present invention relate to an operation panel cover.

Background Art

[0002] Panels (operation panels) such as on-site operation panels installed on the floor surface at a construction site are often placed in an environment where construction equipment and tools that are moved along with the surrounding work come into contact with or collide with them, or are exposed to rain and wind.

[0003] If the operation panel is damaged or rusted due to contact with the operation panel or rain and wind, it will not only damage the aesthetics of the operation panel itself, but may also have an adverse effect on the function of the operation panel.

[0004] Therefore, at some construction sites, the operation panel in operation may be covered with a buffer material or a protective cover to prevent damage and rust of the operation panel. However, the protective cover needs to be removed from or placed on the operation panel each time the operation panel is operated, which makes handling complicated.

[0005] In addition, for example, if the protective cover is blown by strong wind, a part of the blown protective cover may interfere with the operation elements (such as switches) of the operation panel, causing a risk of malfunction.

[0006] Conventionally, a roofing frame is attached to the outside of the panel above the panel, a transparent airtight sheet covering the panel is placed from above the roofing frame, a fastener part serving as an entrance and exit for workers is provided in a part of this sheet, the sheet is fixed to the floor surface with a weight, and a curing device for the panel provided with a waterproof weir on the floor surface around the panel in the sheet has been considered (see, for example, Patent Document 1).

SUMMARY OF THE INVENTION

PROBLEMS TO BE SOLVED BY THE INVENTION

[0008] Conventional curing devices for boards are effective from the viewpoint of curing the boards. However, on the other hand, they require a space for workers to enter and a roof frame and weights for maintaining the outer shape of the transparent airtight sheet covering the boards, occupying an installation space much larger than the boards and involving large-scale installation and removal work.

[0009] The problem to be solved by the present invention is to provide an operation panel cover that allows the operator to be operable with the cover attached without a part of the cover interfering with the operator, and that can be easily attached and removed without occupying an installation space much larger than the operation panel.

MEANS FOR SOLVING THE PROBLEMS

[0010] The operation panel cover of the embodiment is an operation panel cover for an operation panel having an operation panel on the front surface, a plurality of buffer members attached along each edge extending from the upper corner to the lower part of the operation panel, a spacer portion that is integrally provided with the buffer members for the panel attached to the left and right edges of the operation panel among the plurality of buffer members and protrudes forward from the front surface of the operation panel by a predetermined length, a transparent protective cover having a size corresponding to the size of the operation panel to which the plurality of buffer members are attached, with the lower surface as an opening surface, and being mounted so as to cover the upper part of the operation panel, and an operation window provided so as to be openable and closable in a range corresponding to the operator of the operation panel of the protective cover.

[0019] The operation panel cover 10 includes a protective cover 11 having rectangular surfaces corresponding to the front, back, left and right side surfaces, and the upper surface of the rectangular parallelepiped operation panel 1 respectively, and the lower surface being an opening surface. The protective cover 11 is formed using a transparent material with high heat resistance and weather resistance such as soft transparent vinyl chloride (PVC). For example, after aligning its opening surface with the upper part of the operation panel 1, it is mounted so as to cover the lower part of the operation panel 1.

[0020] The protective cover 11 includes a panel cover portion 11P covering the front, upper, left and right side surfaces of the operation panel 1P, and a main body cover portion 11H covering the upper, left and right side surfaces, and the back surface of the panel main body 1H.

[0021] In the protective cover 11, at the L-shaped boundary between the panel cover portion 11P and the main body cover portion 11H in the range from the upper left end to the lower right end of the front surface of the panel main body 1H where the operation panel 1P opens and separates from the panel main body 1H in a fan shape, a waterproof fastener 12 made of plastic, for example, is provided. The operation panel 1P can be opened and closed according to the operation of the opening / closing lever LK with respect to the panel main body 1H by opening the waterproof fastener 12.

[0022] In addition, the operation panel cover 10 is provided with a panel left safety cushion (buffer member for the panel left) 13L having an L-shaped cross-section, which is attached to the inner surface of the left side on the front side of the panel cover portion 11P along the left side edge extending from the upper left corner to the lower part of the front of the operation panel 1P, and a panel right safety cushion (buffer member for the panel right) 13R having an L-shaped cross-section, which is attached to the inner surface of the right side on the front side of the panel cover portion 11P along the right side edge extending from the upper right corner to the lower part of the front of the operation panel 1P.

[0023] In addition, the operation panel cover 10 is provided with a main body left safety cushion (buffer member for the main body left) 15L having an L-shaped cross-section, which is attached to the inner surface of the left side of the main body cover portion 11H along the bent edge extending from the left side of the upper surface of the panel main body 1H to the upper left corner (upper right corner in FIG. 4) of the back surface and reaching its lower part, and a main body right safety cushion (buffer member for the main body right) 15R having an L-shaped cross-section, which is attached to the inner surface of the right side of the main body cover portion 11H along the bent edge extending from the right side of the upper surface of the panel main body 1H to the upper right corner (upper left corner in FIG. 4) of the back surface and reaching its lower part.

[0024] The panel left safety cushion 13L, the panel right safety cushion 13R, the main body left safety cushion 15L, and the main body right safety cushion 15R are made of a lightweight elastic material such as foamed rubber (NBR), protect the corners and edges of the operation panel 1, and buffer the contact with the operator.

[0025] Both the panel left safety cushion 13L and the panel right safety cushion 13R integrally have a left safety cushion spacer portion 14L and a right safety cushion spacer portion 14R that protrude in a predetermined length (depth) in the forward direction (the direction away from the front of the operation panel 1P) from the upper end to the lower end of the operation panel 1P.

[0026] The left safety cushion spacer part 14L and the right safety cushion spacer part 14R function to maintain a space with a predetermined depth (for example, 250 mm) between the operation panel 1P and the inside of the front surface of the panel cover part 11P, and prevent interference between the panel cover part 11P and the operation panel 1P (operating element) when the panel cover part 11P is deflected by, for example, strong wind.

[0027] That is, the height of the operation panel cover 10 (protective cover 11) is configured to include the thickness of the parts where the panel left safety cushion 13L, the panel right safety cushion 13R, the main body left safety cushion 15L, and the main body right safety cushion 15R respectively wrap around the upper surface of the operation panel 1, and the width of the operation panel cover 10 (protective cover 11) is configured to include the thickness of the parts where the respective safety cushions 13L, 13R, 15L, and 15R wrap around the left and right side surfaces of the operation panel 1.

[0029] Note that the height of the operation panel cover 10 (protective cover 11) is made shorter than the height of the operation panel 1 plus the thickness of the parts where the respective safety cushions 13L, 13R, 15L, and 15R wrap around the upper surface of the operation panel 1 by a predetermined length (for example, 50 mm), and in a state where the operation panel cover 10 is attached to the operation panel 1, a gap for heat dissipation is maintained between the peripheral edge of the opening surface at the lower end of the protective cover 11 and the installation surface (floor surface) of the operation panel 1.

[0030] The left panel safety cushion 13L and the right panel safety cushion 13R are respectively attached to the inner surfaces of the left side and the right side on the front side of the panel cover portion 11P at, for example, three locations each in the upper, middle, and lower portions by panel safety cushion attachment members PL1, PL2, PL3 and PR1, PR2, PR3 as shown in FIGS. 1 to 3.

[0031] FIG. 5 is a perspective view showing a partially extracted state in which the left panel safety cushion 13L is attached to the inner surface of the left side on the front side of the panel cover portion 11P by the panel safety cushion attachment members PLn (n = 1 to 3).

[0032] Note that the right panel safety cushion 13R is also attached to the inner surface of the right side on the front side of the panel cover portion 11P by the panel safety cushion attachment members PRn (n = 1 to 3) in the same manner as the left panel safety cushion 13L.

[0033] For the panel safety cushion attachment members PLn (PRn), for example, hook-and-loop fasteners are used to attach the left (right) panel safety cushion 13L (13R) to the inner surface of the left (right) side on the front side of the panel cover portion 11P so as to surround it with the hook-and-loop fasteners PLn (PRn). Instead of the method of attaching so as to surround with the hook-and-loop fasteners PLn (PRn), a magnetic tape may be used to attach the left (right) panel safety cushion 13L (13R) so as to be adsorbed to the inner surface of the left (right) side on the front side of the panel cover portion 11P.

[0034] Also, the left main body safety cushion 15L and the right main body safety cushion 15R are respectively attached to the inner surfaces of the left and right sides and the rear side (corresponding to the upper rear side) on the upper surface side of the main body cover portion 11H corresponding to the positions where the left main body safety cushion 15L and the right main body safety cushion 15R are provided and the inner surfaces of the left and right sides on the rear side of the main body cover portion 11H by main body safety cushion attachment members HL1 to HL6 and HR1 to HR6 provided, for example, at six locations each as shown in FIGS. 1, 3, and 4.

[0035] FIG. 6 is a perspective view showing a partially extracted state in which the main body right safety cushion 15R is attached to the inner surface of the right side (left side in FIG. 4) on the back side of the main body cover portion 11H by the main body safety cushion attachment members HRn (n = 1 to 6).

[0036] Note that the main body left safety cushion 15L is also attached to the inner surface of each corresponding side of the main body cover portion 11H by the main body safety cushion attachment members HLn (n = 1 to 6) in the same manner as the main body right safety cushion 15R.

[0037] For the main body safety cushion attachment members HRn (HLn), similar to the panel safety cushion attachment members PRn (PLn), for example, hook-and-loop fasteners are used, and the main body right (left) safety cushion 15R (15L) is attached to the inner surface of the right side (left side) on the back side of the main body cover portion 11H so as to be surrounded by the hook-and-loop fasteners HRn (HLn). Note that instead of the attachment method of surrounding by the hook-and-loop fasteners HRn (HLn), a magnetic tape may be used to attach the main body right (left) safety cushion 15R (15L) so as to be adsorbed to the inner surface of the right side (left side) on the back side of the main body cover portion 11H.

[0038] Also, on the front surface of the panel cover portion 11P, for example, as shown in FIGS. 1 to 3, a panel operation window 16 for operating the various operators is provided in a size corresponding to the range where at least various operators (opening / closing lever LK, switch lever LS, switch button BS, etc.) of the operation panel 1P are provided.

[0039] FIG. 7 is a front view showing an enlarged view of the panel operation window 16 (open state) in the panel cover portion 11P.

[0040] The panel operation window 16 of the panel cover part 11P is provided corresponding to, for example, a rectangular range where various operators of the operation panel 1P are provided. The panel operation window 16 is provided so as to be openable and closable in a U shape with its left side cantilevered for the rectangular range, and the upper side part, right side part, and lower side part of the U-shaped panel operation window 16 are all detachably provided at an arbitrary length via a window opening / closing surface fastener 17 with respect to the panel cover part 11P.

[0041] With the operation panel cover 10 (protective cover 11) attached to (covering) the operation panel 1, while protecting the operation panel 1, the panel operation window 16 of the panel cover part 11P can be opened and closed to operate various operators of the operation panel 1P.

[0042] FIG. 8 is a plan view showing the movement when opening and closing the operation panel 1P with respect to the panel body 1H with the operation panel cover 10 attached to the operation panel 1.

[0043] By opening the waterproof fastener 12 provided at the L-shaped boundary between the panel cover part 11P and the main body cover part 11H in the range from the left end of the upper side to the lower end of the right side on the front surface of the panel body 1H as needed, as shown by the arrow X, the operation panel 1P can be opened and closed while covering the panel cover part 11P, and for example, operations can be performed on various devices built in the panel body 1H and various devices provided on the back surface of the operation panel 1P.

[0044] As shown in FIGS. 1, 3, 4, and 8, near the center inside each of, for example, the left and right side surfaces and the back surface of the main body cover part 11H in the operation panel cover 10, a desiccant pocket 18 for removably containing a desiccant such as silica gel is provided. By putting a desiccant in the desiccant pocket 18, moisture prevention inside the operation panel cover 10 can be achieved.

[0045] (Attachment and removal of the operation panel cover 10 to / from the operation panel 1) The operation panel cover 10 attaches the panel left safety cushion 13L and the panel right safety cushion 13R to the inner surfaces of the left and right sides of the front of the panel cover portion 11P in the protection cover 11 by the panel safety cushion attachment members PL1 to PL3 and PR1 to PR3, and also attaches the main body left safety cushion 15L and the main body right safety cushion 15R to the inner surfaces of the left and right sides of the back of the main body cover portion 11H by the main body safety cushion attachment members HL1 to HL6 and HR1 to HR6.

[0046] Then, while aligning the opening surface of the lower surface of the operation panel cover 10 with the upper part of the operation panel 1 to which the respective safety cushions 13L, 13R, 15L, 15R are attached, and aligning the respective safety cushions 13L, 13R, 15L, 15R with the four corners of the upper part of the operation panel 1, the operation panel cover 10 can be simply placed over the operation panel 1 for easy installation.

[0047] The operation panel cover 10 attached to the operation panel 1 can be easily removed by simply pulling it out from the upper part of the operation panel 1. Further, the operation panel cover 10 removed from the operation panel 1 can have the respective safety cushions 13L, 13R, 15L, 15R removed from the protection cover 11 and can be easily disposed of by appropriately folding or cutting them.
