Description

FIELD OF THE INVENTION The present invention relates to legs for fixtures.

As a fixture, for example, a simple bed is known in which poles are inserted into both sides of bed cloth, and the poles are removably connected to a support frame via clips. The support frame is connected to the connection frame. Hereinafter, the bed cloth supported by the poles may be referred to as the top plate. According to this fixture, the load of the user lying on the bed cloth is supported by bringing the connecting frame into contact with the ground. Fixtures can be easily disassembled, assembled, folded and unfolded. Therefore, for example, it is possible to use the fixture outdoors, such as camping (for example, see Patent Document 1).

Japanese Patent Application Publication No. 2014-91046

However, when the fixture of Patent Document 1 is used outdoors, it is conceivable that the fixture may fall over due to the influence of wind, for example. Further, when the fixture is used outdoors, it is conceivable to use the top plate at two height positions, a high position and a low position, depending on the environment, for example. However, in the fixture of Patent Document 1, the height of the top plate cannot be changed to two height positions, a high position and a low position, depending on the environment.

The present invention provides fixture legs that can improve the stability of fixtures when a top plate that can be changed to two height positions, a high position and a low position, is placed at each height position. The purpose is to provide.

In order to solve the above problems, the present invention proposes the following means.
(1) The fixture leg according to the present invention is a fixture leg that allows the top plate of the fixture to be placed in a high position and a low position, and includes a base provided on a support part that supports the top plate; a fixing part that is provided on the base and is disposed upwardly away from the ground when the top plate is in the high position, and in contact with the ground when the top plate is in the low position; a fixing string that is provided on the fixing part and pulls the fixing part downward by being held on the ground by the driven stake when the top plate is at the high position; It has a hole into which a stake can be inserted from above, and when the top plate is at the low position, it is fixed to the ground by the driven stake inserted into the hole from above, and the hole has an opening direction. is directed toward the outside of the top plate.

According to this configuration, when the top plate is in a high position, the fixing part is arranged upwardly from the ground. Furthermore, by holding the fixing string on the ground with a driven stake, the fixing part can be pulled downward by the fixing string. Therefore, when the top plate is in a high position, the fixing part can be stabilized with the fixing string. Thereby, the stability of the fixture with the top plate placed at a high position can be improved.

Also, when the top plate is in a low position, the fixing part is placed in contact with the ground. In addition, the fixing part has a hole so that a driven stake can be inserted into the hole from above. Furthermore, when the top plate is in a low position, the fixed part is fixed to the ground by the driven stake by inserting the driven stake into the hole from above. In addition, the opening direction of the hole was made to face the outside of the top plate. Therefore, the driving stake inserted into the hole can be driven into the ground using a driving tool such as a hammer from the outside of the top plate without interfering with the top plate or the like. This makes it possible to improve the stability of a fixture whose top plate is placed at a low position.
In this way, the stability of the fixture can be improved in a state where the top plate, which can be changed to two height positions, high position and low position, is arranged at each height position.

(2) In the above aspect, the opening direction of the hole may be inclined toward the outside of the top plate.

According to this configuration, the opening direction of the hole is inclined toward the outside of the top plate. Therefore, for example, in a state where the hole is arranged inside the top plate, the opening direction of the hole can be directed to the outside of the top plate. Thereby, the length of the fixing part can be kept short. Therefore, for example, when the fixture is disassembled or folded and transported, the fixture can be kept compact by preventing the fixing portion from protruding greatly.

(3) In the above aspect, the fixing portion may extend from the base toward the outside of the top plate with a length of 8 cm to 9 cm.

Here, if the length of the fixing part is less than 8 cm, the fixing part will be too short and it will be difficult to ensure the stability of a fixture in which the top plate is placed at a low or high position. On the other hand, if the length of the fixed part exceeds 9 cm, the fixed part is too long and it is difficult to compact the fixture when disassembling or folding it for transportation.
Therefore, in this configuration, the fixing portion is made to extend from the base toward the outside of the top plate by a length of 8 cm to 9 cm. This makes it possible to ensure the stability of fixtures with top plates placed at low or high positions, and to make the fixtures compact when disassembled or folded.

(4) The above aspect includes a leg frame that is attached to the base when the top plate is placed at the high position, and the fixing string is formed shorter than the length of the leg frame and is expandable. Good too.

According to this configuration, the fixing string is formed shorter than the leg frame, making it expandable and retractable. Therefore, the fixed string can be stretched while the fixed string is held on the ground by the driven stake. Thereby, the fixing portion can be reliably pulled downward by the contractile force (reaction force) generated in the fixing string. Therefore, the stability of the fixture with the top plate placed at a high position can be ensured.

(5) In the above aspect, the fixing part may have a groove formed on the lower surface so as to be able to receive the fixing string.

According to this configuration, a groove is formed on the lower surface of the fixing part, and the fixing string can be received in the groove. Therefore, when a fixture with a top plate placed at a low position is stabilized by the fixed part, the entire lower surface of the fixed part can be brought into contact with the ground by receiving (accommodating) the fixing string in the groove part. Thereby, the stability of the fixture whose top plate is disposed at a low position can be better ensured by the fixing portion.

According to the present invention, the fixture leg can improve the stability of the fixture when a top plate that can be changed to two height positions, a high position and a low position, is placed at each height position. can provide the following.

Hereinafter, the longitudinal direction of the cot 1 will be referred to as a "longitudinal direction", and the lateral direction perpendicular to the longitudinal direction will be referred to as a "horizontal direction". Further, the bed cloth 8 side will be described as "upper", and the leg unit 10 side will be described as "lower". In the drawings, the vertical direction is indicated by arrow A, the horizontal direction is indicated by arrow B, and the vertical direction is indicated by arrow C.

<Frame structure>
The frame structure 2 includes a plurality of connection frames 15 and a pair of support frames 16. In the embodiment, three frame structures 2 arranged at intervals in the vertical direction will be described as an example, but the number of frame structures 2 can be arbitrarily selected. The plurality of connection frames 15 are removably connected to a pair of connection blocks 26 (described later) in the leg unit 10 by having both ends inserted into the pair of connection blocks 26 (described later). In this state, the plurality of connection frames 15 are arranged laterally.

The pair of support frames 16 are removably connected to the pair of connection blocks 26 by inserting their lower ends into the pair of connection blocks 26, respectively. In this state, the pair of support frames 16 are respectively raised from the pair of connecting blocks 26 . In this state, the frame structure 2 and the pair of connecting blocks 26 are formed into a U-shape.
A lock lever 4 is provided at the upper end of one of the pair of support frames 16 . Further, a clamp 18 is provided at the upper end of the other support frame 16 of the pair of support frames 16 .

<Lock lever>
The lock lever 4 is swingably (rotatably) connected to the upper end of one of the support frames 16 via a support shaft (not shown). The lock lever 4 is provided with a clamp 18 at its upper end. The lock lever 4 is locked along one support frame 16 by swinging in the direction of arrow Y around a support shaft (not shown) up to one support frame 16.

<Pole, bed cloth>
One of the pair of poles 6 is removably connected to a clamp 18 provided at the upper end of the lock lever 4. The other of the pair of poles 6 is detachably connected to a clamp 18 provided at the upper end of the other support frame 16. A bed cloth 8 is attached to the pair of poles 6. The bed cloth 8 is formed into a rectangular shape that is elongated in the vertical direction, and a plurality of fitting portions 8a are formed on both long sides. One of the poles 6 is inserted into the insertion part 8a on one side of both sides, and the other pole 6 is inserted into the insertion part 8a on the other side of both sides.
As a result, when the poles 6 are connected to the pair of clamps 18, by locking the lock lever 4 along one of the support frames 16, the pair of poles 6 can be used to spread the bed cloth 8 laterally. It can be supported by the structure 2.

<Leg unit>
The leg unit 10 includes a plurality of first legs (fixture legs) 20 and a plurality of second legs 22. The leg unit 10 is used when the bed cloth 8 of the cot 1 is placed at the high position H1 (the position shown in FIG. 1), and when it is used with the bed cloth 8 placed at the low position H2 (the position shown in FIG. 2). It is configured so that it can be switched between.

<First leg>
The first leg portions 20 are provided at lower portions of both horizontal ends of the frame structure 2 disposed at one end of the plurality of frame structures 2 in the vertical direction. Furthermore, the first leg portions 20 are provided at lower portions of both horizontal ends of the frame structure 2 disposed at the other end in the vertical direction. That is, in the embodiment, four first leg parts 20 are provided as the plurality of first leg parts 20.

Here, at the bottom of both ends of the frame structure 2, the first leg portion 20 provided at one end in the lateral direction and the first leg portion 20 provided at the other end in the lateral direction are connected to the center line of the cot 1. It is formed symmetrically with respect to CL. The center line CL is a straight line passing through the center in the horizontal direction and extending in the vertical direction. Therefore, each constituent member of the first leg 20 provided at one end and the first leg 20 provided at the other end is given the same reference numeral, and the first leg 20 provided at one end is simply referred to as " It will be abbreviated as "first leg section 20" and will be described in detail, and explanation of the first leg section 20 provided at the other end will be omitted.

As shown in FIGS. 3 and 4, the first leg section 20 includes a connecting block (base) 26, a pair of leg frames 28, and a fixing mechanism 30. The pair of leg frames 28 are used only when the bed cloth 8 is placed at the high position H1 in the leg unit 10. That is, the first leg portion 20 can be assembled in a state in which the bed cloth 8 is disposed at the high position H1 and in a state in which the bed cloth 8 is disposed in the low position H2. First, with reference to FIGS. 3 and 4, an example will be described in which the first leg portion 20 is assembled so that the bed cloth 8 is placed at the high position H1 (see FIG. 1).

<Connected block>
The connecting block 26 is removably provided at one end lower part of the frame structure 2 . The connecting block 26 has a pair of leg frame receivers 32 . The pair of leg frame receivers 32 are open at the bottom. The upper end portions of the pair of leg frames 28 are respectively inserted from below into the pair of leg frame receivers 32 and removably connected thereto.

<Leg frame>
The lower ends 28a of the pair of leg frames 28 contact the ground Gr in a state where the upper ends are removably connected to the pair of leg frame receivers 32. By bringing the lower ends 28a of the pair of leg frames 28 into contact with the ground Gr, the bed cloth 8 of the cot 1 can be placed (held) at a high position H1 (see FIG. 1). That is, the first leg portion 20 is assembled in such a state that the bed cloth 8 is placed at the high position H1.
The pair of leg frames 28 has an uneven anti-slip surface formed on the lower surface of the lower end portion 28a. This makes it difficult for the lower surfaces of the pair of leg frames 28 to move relative to the ground Gr. That is, the pair of leg frames 28 can be placed in a stable state with respect to the ground Gr.

Next, referring to FIGS. 5 and 6, an example will be described in which the first leg portion 20 is assembled so that the bed cloth 8 is placed at the low position H2 (see FIG. 2).
As shown in FIGS. 5 and 6, when the bed cloth 8 of the cot 1 is placed at the low position H2, the pair of leg frames 28 (see FIGS. 3 and 4) are inserted from the pair of leg frame receivers 32. Remove. Thereby, the fixing mechanism 30 is brought into contact with the ground Gr, and the bed cloth 8 of the simple bed 1 can be placed (held) at the low position H2.

<Fixing mechanism>
As shown in FIGS. 3 to 6, the fixing mechanism 30 is provided at the bottom of the connecting block 26. As shown in FIGS. The fixing mechanism 30 is a mechanism that stabilizes the cot 1 when the bed cloth 8 is placed at a high position H1 (see FIG. 1) or when the bed cloth 8 is placed at a low position H2 (see FIG. 2). Specifically, the fixing mechanism 30 includes a grounding part 35, a fixing part 36, and a fixing string 37.
<Grounding part>
The grounding portion 35 is formed in a rectangular shape in plan view, and is integrally provided at the lower part of the connecting block 26. The lower surface 35a of the grounding portion 35 contacts the ground Gr when the bed cloth 8 of the cot 1 is placed at the low position H2. The grounding portion 35 has an uneven anti-slip surface formed on the lower surface 35a. This makes it difficult for the lower surface 35a of the grounding portion 35 to move relative to the ground Gr. That is, the grounding portion 35 can be placed in a stable state with respect to the ground Gr.

<Fixed part>
The fixing part 36 is integrally formed with the grounding part 35 and extends laterally from the outer side 35b of the grounding part 35 toward the outside of the bed cloth 8. That is, the fixing part 36 is integrally provided with the connecting block 26 via the grounding part 35. The fixing part 36 is, for example, formed in a plate shape with a constant width and a constant thickness, and a lower surface 36a is formed slightly above the lower surface 35a of the grounding part 35. For example, the fixing portion 36 has a distal end portion 36b formed in a convex curve when viewed from above.
The fixing part 36 and the grounding part 35 are arranged apart upward from the ground Gr when the bed cloth 8 is arranged at the high position H1 (see FIG. 3). Further, the fixing part 36 and the grounding part 35 are arranged in contact with the ground Gr when the bed cloth 8 is arranged at the low position H2 (see FIG. 5).

The fixed portion 36 has a length L1 of 8 cm to 9 cm from the leg frame receiving portion 32 (ie, the connecting position of the leg frame 28) to the tip end 36b. Hereinafter, the length L1 from the leg frame receiving portion 32 to the tip end portion 36b may be referred to as the fixed portion length L1. The reason why the fixed portion length L1 is set to 8 cm to 9 cm will be explained in detail later.

As shown in FIGS. 7 and 8, the fixing part 36 has a fixing hole (hole part) 41, a mounting hole 42, and a groove part 43. The fixing hole 41 is formed near the tip portion 36b. The fixing hole 41 is penetrated so that a driven stake 45 such as a peg can be inserted from above. Specifically, the fixing hole 41 is formed into an ellipse along the longitudinal direction (that is, the lateral direction) of the fixing portion 36 . The fixing hole 41 is formed so that the ellipse of the lower surface 36a is larger than the ellipse of the upper surface 36c of the fixing portion 36.

In the embodiment, the fixing hole 41 is formed in the upper surface 36c into an ellipse having a length in the major axis direction Lh1 = 16 mm and a width in the minor axis direction Wh1 = 11 mm. Further, the fixing hole 41 is formed in an ellipse shape on the lower surface 36a with a length Lh2=18 mm in the major axis direction and a width Wh2=13 mm in the minor axis direction. Note that the lengths Lh1 and Lh2 in the major axis direction and the widths Wh1 and Wh2 in the minor axis direction can be changed arbitrarily.

Therefore, the fixing hole 41 is formed such that the peripheral wall 41a gradually widens from the upper surface 36c of the fixing portion 36 toward the lower surface 36a. As a result, the inner part 41b of the peripheral wall 41a of the fixing hole 41 (that is, the part on the opposite side of the tip 36b of the fixing part 36) has an extension line 48 in the lateral direction relative to the outer side 8b of the bed cloth 8. sloped outwards. That is, the opening direction of the fixing hole 41 is inclined toward the outside of the outer side 8b along the inner portion 41b of the peripheral wall 41a.
Therefore, with the bed cloth 8 of the simple bed 1 disposed at the low position H2, the driving stake 45 inserted into the fixing hole 41 can be driven into the ground Gr with a driving tool (not shown) such as a hammer. Thereby, the fixing portion 36 can be fixed to the ground Gr by the driven stake 45 inserted into the fixing hole 41.

Note that the fixing hole 41 may be formed so that the upper surface 36c and the lower surface 36a of the fixing portion 36 have the same oval shape so that the opening direction of the fixing hole 41 faces vertically. In this case, the position of the fixing hole 41 is moved to the outside of the outer side 8b of the bed cloth 8 so that the opening direction of the fixing hole 41 faces outward with respect to the outer side 8b of the bed cloth 8.

A mounting hole 42 is formed inside the fixing hole 41 in the lateral direction of the fixing portion 36 . The mounting hole 42 has a fixed oval shape and extends vertically from the upper surface 36c of the fixing portion 36 toward the lower surface 36a. The attachment hole 42 is formed with its long axis facing in the horizontal direction. A fixing string 37 (described later) is attached to the attachment hole 42.

Furthermore, a groove portion 43 is formed in the lower surface 36a of the fixing portion 36. The groove portion 43 is formed in a direction perpendicular to the longitudinal direction of the fixing portion 36 from the attachment hole 42 to one side 36d of the fixing portion 36 with a width that is approximately the same as the length of the attachment hole 42 in the longitudinal direction. The groove portion 43 is formed to be able to receive (storage) the fixed string 37 attached to the attachment hole 42. Therefore, the fixing string 37 extending downward from the attachment hole 42 can be received in the groove 43. Thereby, the fixing string 37 can be prevented from protruding downward from the lower surface 36a of the fixing part 36.

In the embodiment, an example will be described in which the groove 43 is formed from the mounting hole 42 to one side 36d of the fixing part 36, but the groove 43 is formed from one side 36d of the fixing part 36 to the other side 36e. may be formed. However, considering the strength of the fixing part 36, it is preferable to form the groove part 43 from the mounting hole 42 to one side 36d of the fixing part 36.

<Fixed string>
As shown in FIGS. 3 and 7, the fixed string 37 is made of a stretchable member such as rubber, and is formed into an endless shape or a string shape, and is overlapped in a double loop shape. In this state, the fixing string 37 is passed through the attachment hole 42 of the fixing part 36, and both ends of the fixing string 37 are tied. Therefore, the fixing string 37 is provided in the fixing part 36 in a double loop shape. The fixing string 37 hangs downward from the fixing part 36 in a state where it is attached in a double loop shape.
The length L2 of the fixed string 37 from the fixed part 36 to the lower end 37a is shorter than the length L3 of the leg frame 28. The fixing string 37 is held on the ground Gr by a driven stake 45 (see FIG. 8) such as a peg in a state where the bed cloth 8 is placed at a high position H1 (see FIG. 1). In this state, the fixing string 37 can pull the fixing part 36 downward by being kept in a stretched state.

<Second leg>
As shown in FIG. 1, the second leg portions 22 are provided at lower portions of both ends in the horizontal direction of the frame structure 2 arranged at the center in the vertical direction among the plurality of frame structures 2. That is, in the embodiment, two second leg parts 22 are provided as the plurality of second leg parts 22.
Here, at the bottom of both ends of the frame structure 2, the second leg portion 22 provided at one end in the lateral direction and the second leg portion 22 provided at the other end in the lateral direction are connected to the center line of the cot 1. It is formed symmetrically with respect to CL. Therefore, the constituent members of the second leg portion 22 provided at one end and the second leg portion 22 provided at the other end are given the same reference numerals, and the second leg portion 22 provided at one end is simply referred to as “ It will be abbreviated as "second leg section 22" and will be described in detail, and explanation of the second leg section 22 provided at the other end will be omitted.

The second leg portion 22 is the same as the first leg portion 20 except that the fixing portion 36 and the fixing string 37 are removed from the members constituting the first leg portion 20 . Therefore, similarly to the first leg portion 20, by removably connecting the pair of leg frames 28 to the pair of leg frame receiving portions 32, the bed cloth 8 of the simple bed 1 can be placed at the high position H1. That is, the second leg portion 22 is assembled in such a state that the bed cloth 8 is placed at the high position H1.

Further, as shown in FIG. 2, when the bed cloth 8 of the cot 1 is placed at the low position H2, the pair of leg frames 28 (see FIG. 1) are removed from the pair of leg frame receivers 32. Thereby, the ground contact portion 35 can be brought into contact with the ground Gr, and the bed cloth 8 of the simple bed 1 can be placed at the low position H2.

As explained above, according to the first leg part 20 of the embodiment, as shown in FIGS. 1 and 9, the fixing part 36 is separated upward from the ground Gr when the bed cloth 8 is placed at the high position H1. It is now placed as follows. Furthermore, by holding the fixing string 37 on the ground Gr by the driven stake 45, the fixing part 36 can be pulled downward by the fixing string 37. Therefore, the fixing part 36 can be stabilized by the fixing string 37 in a state where the bed cloth 8 is placed at the high position H1. Thereby, the stability of the cot 1 with the bed cloth 8 disposed at the high position H1 can be improved, and for example, it is possible to prevent the cot 1 from falling over.

Further, as shown in FIGS. 8 and 10, when the bed cloth 8 is at the low position H2, the fixing portion 36 is arranged in contact with the ground Gr. Further, the fixing portion 36 has a fixing hole 41, and a driven stake 45 can be inserted into the fixing hole 41 from above. Furthermore, in a state where the fixing hole 41 is arranged at the low position H2, the driving stake 45 is inserted into the fixing hole 41 from above and driven into the ground Gr, so that the fixing part 36 is fixed to the ground Gr by the driving stake 45. I made it.
In addition, the opening direction of the fixing hole 41 is directed toward the outside of the bed cloth 8 when viewed from above. Therefore, the driving stake 45 inserted into the fixing hole 41 can be driven into the ground Gr from outside the bed cloth 8 with a driving tool (not shown) such as a hammer without interfering with the bed cloth 8 or the like. Thereby, the stability of the cot 1 with the bed cloth 8 disposed at the low position H2 can be improved, and for example, it is possible to prevent the cot 1 from falling over.
In this way, the stability of the cot 1 can be improved when the bed cloth 8, which can be changed to two height positions, the high position H1 and the low position H2, is arranged at each height position. .

Furthermore, the opening direction of the fixing hole 41 is inclined toward the outside of the bed cloth 8. Therefore, for example, in a state where the fixing hole 41 is arranged inside the bed cloth 8, the opening direction of the fixing hole 41 can be directed to the outside of the bed cloth 8. Thereby, the length of the fixing portion 36 can be kept short. Therefore, for example, when the cot 1 is disassembled or folded and transported, the fixing portion 36 is prevented from protruding greatly, and the cot 1 can be made compact.

In addition, as shown in FIGS. 6 and 10, the fixed portion length L was set to 8 cm to 9 cm. The reason why the length L of the fixed part was set to 8 cm to 9 cm is as follows.
In other words, if the length of the fixing part 36 is less than 8 cm, the fixing part 36 will be too short, and the stability of the cot 1 with the bed cloth 8 placed at the high position H1 (see FIG. 1) or the low position H2 (see FIG. 2) will be reduced. Difficult to maintain sexuality. On the other hand, if the length of the fixed part 36 exceeds 9 cm, the fixed part 36 will be too long, and it will be difficult to compact the cot 1 when it is disassembled or folded and transported.
Therefore, the fixing part 36 was made to extend from the connecting block 26 toward the outside of the bed cloth 8 by a length of 8 cm to 9 cm. Thereby, the stability of the cot 1 with the bed cloth 8 disposed at the high position H1 or the low position H2 can be ensured, and furthermore, the cot 1 can be disassembled or folded to be compact.

Further, as shown in FIG. 9, the fixing string 37 is formed shorter than the leg frame 28, so that it can be expanded and contracted. Therefore, the fixed string 37 can be stretched while the fixed string 37 is held on the ground Gr by the driven stake 45. Thereby, the fixing portion 36 can be reliably pulled downward by the contractile force (reaction force) generated in the fixing string 37. Therefore, the stability of the cot 1 with the bed cloth 8 disposed at the high position H1 can be ensured.

Furthermore, as shown in FIGS. 2 and 7, a groove 43 is formed in the lower surface 36a of the fixing part 36, so that the fixing string 37 can be received in the groove 43. Therefore, when stabilizing the cot 1 with the bed cloth 8 placed at the low position H2 using the fixing part 36, by receiving (storing) the fixing string 37 in the groove part 43, the entire lower surface 36a of the fixing part 36 is placed on the ground Gr. can be brought into contact with. Thereby, the stability of the cot 1 with the bed cloth 8 disposed at the low position H2 can be further ensured by the fixing portion 36.
