Description

The present invention relates to a holder that can be detachably attached to a support such as a pipe or bar, and temporarily holds an object such as a broom handle or mop handle.

One example of a device that can clamp a mop handle or the like, regardless of the size of the handle's outer diameter, is described in JP 2001-065516 A (Patent Document 1). The clamp described in Patent Document 1 has lever-shaped claws pivotally attached to two pins erected on a base, and clamps the mop handle or the like between the pair of claws. Mounting holes are drilled into each of the four corners of the base. The base is fixed to the wall surface by passing screws or bolts through each mounting hole.

JP 2001-065516 A

However, the inventors have found that there are areas that need to be improved in the conventional clamps described above. Specifically, cleaning workers go to the cleaning site on a dolly, cart, or the like loaded with a set of cleaning tools, and move on each time they finish cleaning. This means that the mop or broom needs to be temporarily stored on a mobile object such as a dolly or cart, but because typical dollies and carts are made up of pipes and bars and do not have walls, there is a problem in that the substrate described in Patent Document 1 cannot be attached to the dolly or cart.

In addition, to improve work efficiency, there is a demand for cleaning workers to be able to store mops and brooms in a location of their choice. On the other hand, the handles, pipes, or bars of dollies and carts can extend horizontally, diagonally, or vertically. Despite this, from the standpoint of convenience, it is preferable to store mops and brooms in a position that extends vertically. Long objects are prone to falling over, and it is not preferable for the bristles of mops and brooms to touch the ground. For this reason, there is a demand for mops and brooms to be stored in an appropriate position, with the bristles pointing downward so that they do not touch the ground, in preparation for starting work.

In addition, since the dolly or cart vibrates when moving, it is necessary to hold the mop or broom steadily against the vibrations caused by the movement.

In view of the above-mentioned circumstances, the present invention aims to provide a tool that can be detachably attached to a movable body having a pipe or a bar, etc., and that can temporarily hold a mop or the like in a specified position.

For this purpose, the holder according to the present invention comprises a first base having a recess that is applied to and supported by a support material and a fixing means that is removably fixed to the support material, a second base that is rotatably connected to the first base, a pair of arms that are erected on the second base and face each other to hold an object by sandwiching it between them, and an angle holder that is provided between the first and second bases and holds the angle between these bases at one predetermined angle selected from a plurality of predetermined angles.

According to the present invention, the holder 10 can be detachably attached to various supports by the fixing means, so that it can be fixed at a desired location. In addition, the second base 21 can be rotated to adjust the position of the pair of gripping parts, so that a broom, mop, etc. can be placed on the holder in an up-down direction, for example, and the cleaning tool can be temporarily held in a suitable position. The recess of the present invention is applied to the rod-shaped handle of a dolly or cart, a pipe or bar support, or a support with corners, so that it can easily engage with the support, and is stably fixed to the support in combination with the fixing means.

The shape and dimensions of the recess are not particularly limited, but in one aspect of the invention, the recess is a groove that extends straight. In this aspect, the groove-shaped recess can be applied to a pipe or bar to secure the holder. In another aspect, the recess is a round or other shaped depression.

In a preferred aspect of the present invention, the angle holding portion is a combination of an engaging portion provided on either the first base portion or the second base portion, and an engaged portion provided on the remaining base portion that selectively engages with the engaging portion. According to this aspect, the rotation angle of the second base portion can be held at a predetermined value. Note that the greater the number of engaging portions and/or engaged members, the greater the opportunities for selective engagement, allowing for finer angle adjustment. The angle holding portion is, for example, a combination of one engaging protrusion and multiple engaging recesses, or a combination of multiple engaging protrusions and one or multiple engaging recesses.

The fastening means may be, but is not limited to, a band, belt, string, fabric, rubber, block, buckle, or a combination of these. In a more preferred aspect of the present invention, the fastening means is a belt having a hook-and-loop fastener on the outer surface and a non-slip surface on the inner surface, which is passed through a hole formed in the first base and wound around the support, with the non-slip surface coming into surface contact with the support. In this aspect, the non-slip surface prevents the holder from rotating. Therefore, the object can be held stably.

In one aspect of the present invention, the fixing means includes a belt body forming the above-mentioned belt, a square ring attached to one end of the belt body, and a branch belt that branches off and extends from one end of the belt body, and both sides of the branch belt are provided with anti-slip surfaces. According to this aspect, the branch belt can be brought into surface contact with the support material, making it possible to fix the holder to a large-diameter support material. In another aspect, the branch belt may be omitted.

The retainer fixing belt of the present invention has a hook-and-loop fastener on the side and a non-slip surface on the inside surface, and is equipped with a belt body that is passed through a long hole formed in the retainer and wrapped around a support that supports the retainer, with the non-slip surface making surface contact with the support, and a square ring attached to one end of the belt body. According to this aspect, the non-slip surface makes it possible to wrap around a support material with a circular cross section such as a pipe without being able to rotate, preventing the retainer from rotating around the support material, and stabilizing the position of the retainer.

In this way, according to the present invention, the holder can be removably fixed to any desired mounting location, so the holder can be securely attached and fixed to any desired position on a dolly or cart made of pipes and bars. In addition, the object can be held in any position. The person using the object can temporarily place the object in the holder in the desired position, improving convenience.

FIG.

The embodiment of the present invention will be described in detail below with reference to the drawings. Figs. 1 to 3 are perspective views showing a holder according to one embodiment of the present invention. The holder 10 is a holder that has a first base 11, a second base 21, a pair of arms 31, and a fixed belt 41, and is used to hold an object with the pair of arms 31. The second base 21 is pivotally attached to the front surface of the first base 11 and can rotate relatively around a center line O. A groove-shaped recess 12 is formed on the back surface of the first base 11, and the fixed belt 41 is attached to it. As can be understood by comparing Figs. 1 to 3, the first base 11 and the second base 21 are connected so as to be able to rotate relatively. Note that the belt is not shown in Fig. 2.

Figure 4 is a plan view showing this embodiment, corresponding to Figure 1. Figure 5 is a plan view showing this embodiment, corresponding to Figure 2. The pair of arms 31 are, for example, both ends of a C-shaped leaf spring, the center of which is fixed to the second base 21, and both ends of the leaf spring extend forward from the second base 21 in an arm-like manner to form the left and right arms 31. When a long object to be held, such as a broom handle or mop handle, which is oriented to extend perpendicularly to the left and right direction, is pressed between the arms 31 facing each other in the left and right direction from the front of the holder 10, the leaf spring elastically deforms, temporarily increasing the distance between the pair of arms 31, and the object is fitted between the pair of arms 31 and gripped.

Conversely, by pulling the grasped object forward, the long object will be released from the pair of arms.

A roller 32 is attached to the tip of the arm 31. The roller 32 is supported by the arm 31 via a shaft 33 that extends perpendicular to the left-right direction and is freely rotatable. The rollers 32 form a pair spaced apart in the left-right direction, making it easy to push in and pull out the long object mentioned above. The outer diameter surface of the roller 32 is provided with irregularities.

A seat 22 is provided in the center of the front surface of the second base 21. The seat 22 is disposed between the pair of arms 31 and abuts against the long object to stabilize the grasped object. The surface of the seat 22 is provided with unevenness (not shown). Such unevenness exerts an anti-slip effect, preventing the grasped long object from slipping off the holder 10.

A pivot shaft 23, shown in FIG. 6, described later, is erected in the center of the back surface of the second base 21. The pivot shaft 23 protrudes rearward, forming a center line O that extends in the front-rear direction, and is inseparably inserted through a center hole 15 formed in the center of the first base 11, realizing relative rotation between the first base 11 and the second base 21.

The relative angle between the first base 11 and the second base 21 can be freely changed, but as shown in Figures 1 to 3, it is maintained at 45 degree intervals, for example, 0 degrees, 45 degrees, and 90 degrees. Such maintenance is due to an angle maintenance part 51 provided between the first base 11 and the second base 21 (Figure 7). Referring to Figure 7, the angle maintenance part 51 is, for example, a combination of a convex engaging part 52 provided on one of the first base 11 and the second base 21 and an engaged part 53 including a hole 55, notch, or recess provided on the remaining other, and the engagement of these convex and concave parts realizes angle change at equal intervals and maintenance of that angle.

In this embodiment, the first base 11 is provided with an engaging portion 52 and a small chamber 54 that houses the engaging portion 52. The engaging portion 52 is biased toward the second base 21 by an elastic member (not shown) and protrudes from the small chamber 54. In contrast, an engaged portion 53 is fixed to the second base 21. The engaged portion 53 is an annular plate, and multiple holes 55 are drilled at equal intervals in the circumferential direction with respect to the center line O. In this embodiment, the holes 55 are arranged at 45 degree intervals with respect to the center line O. The engaging portion 52 is selectively inserted into one of the holes 55 to engage with it. This restricts the rotation of the second base 21.

An inclined surface 56 is formed at the tip of the engaging portion 52. When torque acts between the first base portion 11 and the second base portion 21 in the rotational direction and the torque reaches or exceeds a predetermined value, the engaged portion 53 attempts to overcome the inclined surface 56, pushing the engaging portion 52 into the small chamber 54. This allows the second base portion 21 to rotate.

In other words, from the perspective of the first base 11, the second base 21 is restricted from rotating inadvertently, but is allowed to rotate when a certain amount of rotational torque acts on the second base 21.

Figure 6 is a rear view showing the holder of this embodiment. The recess 12 extends straight like a groove from one edge to the other edge of the back surface of the first base 11. A handle, pipe, or bar (hereinafter referred to as support material 101) that constitutes a dolly, cart, etc. is placed in this recess 12 (Figures 1 to 3). The support material 101 fits into the recess 12, and the first base 11 is prevented from slipping relative to the support material 101.

Each of the ridges 13, 13 that divide both sides of the recess 12 has a long hole 14 formed therein. Each of the ridges 13 and the long hole 14 also extends parallel to the groove-shaped recess 12. The pair of long holes 14 are aligned in a direction transverse to the center line O, and the fixing belt 41 is passed through them. The fixing belt 41 is wound around the support material 101. As a result, the first base 11 is removably fixed to the support material 101. The inner surface of the fixing belt 41 is treated with an anti-slip treatment. This prevents the fixing belt 41 and the first base 11 from rotating around the support material 101. Note that the ridges 13 are a type of protrusion, and as a modified example (not shown), instead of the ridges 13, multiple protrusions may be arranged.

8 is a diagram showing the untied fixing belt 41, showing the outer surface (outer peripheral surface) of the fixing belt 41. FIG. 9 is a diagram showing the untied fixing belt 41, showing the inner surface (inner peripheral surface) of the fixing belt 41. The fixing belt 41 of this embodiment is a type of fixing means for removably fixing the holder 10 to the support material 101, and includes a flexible cloth belt, one end of which is sewn with a square ring 42, and the other end 47 is passed through the long holes 14, 14 of the first base 11 and the long holes of the square ring 42. Referring to FIG. 8, a loop surface 43 of a hook and loop fastener is provided on the outer peripheral surface from the square ring 42 at one end of the fixing belt 41 to the central portion. Also, a hook surface 45 of a hook and loop fastener is provided on the outer peripheral surface from the central portion to the other end 47. This loop surface 43 is smooth, whereas the hook surface 45 is rough.

Referring to FIG. 9, the loop surface 43 described above extends beyond the square ring 42 to one end of the inner peripheral surface of the fixing belt 41. In addition, in the one end region of the fixing belt 41, a non-slip surface 44 is provided on the inner peripheral surface from the end away from the square ring 42 to the center. The non-slip surface 44 is, for example, synthetic leather impregnated with rubber or the like, and has a higher coefficient of friction than the other surfaces. Furthermore, the non-slip surface 44 is provided with fine irregularities, which further increases the coefficient of friction. The outer peripheral surface of the fixing belt 41 from the center to the other end 47 is a smooth surface 46 with a lower coefficient of friction than the other surfaces.

Referring to FIG. 9, in addition to the belt body described above, a single cloth belt branches off and extends from the square ring 42, and both sides of this branch belt 50 are provided with anti-slip surfaces 48, 49.

Figures 10 to 12 are schematic diagrams showing a case where the holder 10 is fixed to a small-diameter support material 101. When the diameter of the support material 101 is less than twice the groove width of the recess 12, as shown in Figure 10, the fixing belt 41 alone removed from the first base 11 is placed on the support material 101, and the other end 47 is passed through the square ring 42 as shown in Figure 11, and the other end 47 is fully pulled out from the square ring 42, so that the fixing belt 41 is first wrapped around the support material 101. At this time, the non-slip surface 48 of the branch belt 50 is in close contact with the non-slip surface 44 of the belt body, and the non-slip surfaces 49 and 44 are in surface contact with the surface of the support material 101. Alternatively, as a modified example not shown, the branch belt 50 may be separated from the belt body, and the non-slip surface 48 may be in surface contact with the surface of the support material 101.

Referring to FIG. 12 following FIG. 11, the other end 47 area of the fixing belt 41 that has passed through the square ring 42 is folded back at the square ring 42, and then the other end 47 of the fixing belt 41 is passed through the long holes 14, 14 of the first base 11, and then the hook surface 45 is attached to the loop surface 43. This ensures that the holder 10 is securely fixed to the support material 101. The non-slip surfaces 44, 49 grip the surface of the support material 101 firmly, so that the holder 10 does not rotate around the support material 101.

Figure 13 is a schematic diagram showing the case where the holder 10 is fixed to a large-diameter support material 101. For ease of understanding, in Figures 10 and onwards, the other end 47 of the fixing belt 41 is loosely pulled out and tightened, but in actual fixing, the other end 47 of the fixing belt 41 is pulled out strongly and tightly tightened. If the diameter of the support material 101 is more than twice the groove width of the recess 12, the other end 47 of the fixing belt 41 is first passed through the long holes 14, 14 of the first base 11, and the fixing belt 41 with the first base 11 is applied to the support material 101. At this time, the slip-resistant surface 44 of the belt body is in surface contact with the surface of the support material 101, while the branch belt 50 is separated from the belt body, and the slip-resistant surface 48 is in surface contact with the surface of the support material 101. This allows the entire circumference of the large-diameter support material 101 to be gripped.

Then, the fixing belt 41 is wrapped around the support material 101, the other end 47 is passed through the square ring 42 and folded back, and the hook surface 45 is attached to the loop surface 43. This ensures that the holder 10 is securely fixed to the support material 101. The non-slip surfaces 44 and 48 grip the surface of the support material 101 firmly, so that the holder 10 does not rotate around the support material 101.

The holder 10 of this embodiment includes a first base 11 having a recess 12 that is supported by the support material 101 and a fixing belt 41 as a fixing means that is removably fixed to the support material 101, a second base 21 that is rotatably connected to the first base 11, a pair of arms 31 that are erected on the second base 21 and face each other to hold an object such as a broom handle, and an angle holder 51 that is provided between the first base 11 and the second base 21 and holds the angle between these bases at one predetermined angle selected from a plurality of predetermined angles, so that it can be removably fixed to any support material 101. In addition, by rotating the second base 21 to any angle, the object can be held in any position. Therefore, for example, by arranging the pair of arms 31 in the left-right direction, the broom handle can be placed on the holder 10 in a position extending in the up-down direction, improving convenience. In addition, the holder 10 can be fixed at any location, improving convenience. In particular, even if the extension direction of the support material 101 is not preferable, the broom handle can be adjusted to a position that extends in the vertical direction, improving convenience.

Although the embodiment of the present invention has been described above with reference to the drawings, the present invention is not limited to the illustrated embodiment. Various modifications and variations can be made to the illustrated embodiment within the same scope as the present invention or within an equivalent scope.
