Description

  The present invention relates to a folding frame for tents and an assembled tent for medical use.

Conventionally, various folding frames of a rectangular tent having a bellows-like stretchable part in plan view have been proposed (Patent Documents 1 to 4).
Specifically, Patent Documents 1 to 4 disclose tent-type folding frames having the following configuration. In this conventional folding frame, a bellows-like stretchable part having at least one x-shaped part in which two pipe-like members are connected to each other in an X-shape so as to be pivotable at a central intersection, and four And a support post. The four struts are arranged in four corners of a quadrangle in plan view, and bellows-like stretchable parts are arranged on the four sides of the front, rear, left and right of the quadrangle. Each of the upper end portion located above the two pipe-shaped members constituting the end portion of the bellows-like stretchable portion and the lower end portion located below is rotatably attached to the support via the attachment portion, The upper end mounting portion is non-slidable with respect to the column, and the lower end mounting portion is slidably mounted along the longitudinal direction of the column. And each of the support | pillar arrange | positioned at said quadrilateral square has two attachment parts, an upper attachment part and a lower attachment part, regarding the attachment part. The upper mounting portion is not slidable and pivotable at the two upper end portions of the two bellows-like stretchable portions, either front or rear and either left or right, on the pillars arranged in the four corners of the quadrangle. It attaches as possible. The lower mounting portion is slidable and pivotable at the two lower end portions of the two bellows-like stretchable portions, either the front or rear and the left or right, on the pillars arranged in the four corners of the quadrangle. It attaches as possible.

  In the folding frames according to these Patent Documents 1 to 4, as described above, only one attachment portion, that is, an upper attachment portion and a lower attachment portion, is provided on one support column. The two lower end portions of the two bellows-like stretchable parts, either the front or the rear and the left or right, can be slid and rotated on the pillars arranged in the four corners of the quadrangle. When attached to the stretched state from the collapsed state in which each of the bellows-like stretchable parts is contracted, all the bellows-like stretchable parts in the front, rear, left and right are stretched simultaneously. As a result, the quadrangular frame is completed with a single touch, but if there is no open space corresponding to the size of the quadrangular frame after completion, it cannot be stretched smoothly, and conversely, it cannot be contracted. It has a drawback.

  In the frames described in Patent Documents 1 to 4, when the strut spreads, the four bellows-like stretchable parts of the front and rear and the left and right spread simultaneously. As a result, considering the right front strut, the right rear strut is The left front strut moves leftward, and the left rear strut moves diagonally to the left rear. That is, unless the left rear column on the diagonal of the completed quadrangular frame moves, the tent frame cannot be expanded or contracted.

  As a result, for example, in a state where one medical bed in a hospital is placed in the storage, a tent having a sealing property is stretched around the tent so that the inside of the tent storing the bed and the outside Even if you try to divide the space, the tent frame cannot be expanded or contracted unless the left rear column on the diagonal line of the quadrangular frame moves, so the bed (the bed where the observer is sleeping) In addition, the struts collide with each other, so that the tent frame cannot be contracted.

  Therefore, an open space corresponding to the size of the completed quadrangular frame is secured on the side of the bed, and after the tent frame is extended in this open space, the bed is moved or the tent frame is moved. The bed will be accommodated in the tent. However, a large space is not necessarily secured in a hospital room or a medical office, and a situation in which a tent cannot be practically caused occurs.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of a tent according to an embodiment of the present application.
2A is a plan view and a side view of the tent frame in a folded state, and FIG. 2B is a plan view of a process of extending the left bellows-like stretchable part and the right bellows-like stretchable part from the folded state of the tent frame. (C) is a plan view and a side view in a state where the left bellows-like stretchable part and the right bellows-like stretchable part of the tent frame are extended.
FIG. 3A is a plan view of the tent frame, and FIG. 3B is a front view.

  As shown in FIG. 1, the tent according to this embodiment includes a seat and a frame. The sheet includes a top sheet s1 having a substantially rectangular shape in plan view and a side sheet s2 suspended from its four sides, and the lower end of the side sheet s2 is in a grounded state while being supported by a stretched frame. Thus, an internal space partitioned from the outside is formed.

  The frame includes four struts and a bellows-like stretchable part supported between the four struts. The struts are composed of a left front strut 1a, a left rear strut 1b, a right front strut 1c, and a right rear strut 1d arranged in four corners of a square in plan view. The bellows-like stretchable part is supported between these columns, and includes a left bellows-like stretchable part 21, a right bellows-like stretchable part 22, a front bellows-like stretchable part 23, and a rear bellows-like stretchable part 24. In this example, the struts that expand and contract in two steps are used, but non-expandable types may be used, and a plurality of columns may be connected.

  Each bellows-like expansion-contraction part is provided with the x-shaped part 13 which connected the two linear pipes 11 in X shape, as shown in FIG. The two pipes 11 are connected to each other at a central intersection 12 so as to be rotatable. The left bellows-like stretchable part 21 and the right bellows-like stretchable part 22 are formed by connecting two x-shaped parts 13. The connection method is such that the ends of the two pipes 11 forming one x-shaped portion 13 and the ends of the two pipes 11 forming another one x-shaped portion 13 are connected to each other by the connecting portion 14. It is connected so that it can rotate. As shown in FIG. 3, the front bellows-like stretchable part 23 and the rear bellows-like stretchable part 24 are each constituted by only one x-shaped part 13.

  Here, the pipe 11 can be a hollow pipe made of a metal such as aluminum or steel or a synthetic resin, but a solid long member can also be used. The cross-sectional shape may be circular or polygonal, and these are referred to as a pipe-like member. The number of x-shaped parts 13 constituting each bellows-like stretchable part can be appropriately changed to one or more.

  Of the two pipes 11 constituting the end portion of each bellows-like stretchable portion, the end portion of the pipe 11 positioned above (hereinafter referred to as the upper end portion 15) and the end portion positioned below (hereinafter referred to as the lower end portion) Each of 16) is attached to four support columns so as to be rotatable via an attachment portion.

  The above-mentioned mounting parts are provided with three upper mounting parts 31, a middle mounting part 32, and a lower mounting part 33 for each column. The upper mounting portion 31 provided on the left front column 1a is configured to mount the left bellows-like stretchable portion 21 and the upper end 15 of the front bellows-like stretchable portion 23 so that they cannot slide and can be turned up and down. The upper attachment portion 31 provided on the left rear column 1b attaches the left bellows-like stretchable portion 21 and the upper end 15 of the rear bellows-like stretchable portion 24 so as not to be slidable and rotatable up and down. The upper mounting portion 31 provided on the right front support column 1c is for mounting the right bellows-like stretchable portion 22 and the upper end portion 15 of the front bellows-like stretchable portion 23 so as not to be slidable and rotatable up and down. The upper attachment portion 31 provided on the right rear column 1d is for attaching the upper end 15 of the right bellows-like stretchable portion 22 and the rear bellows-like stretchable portion 24 so as not to be slidable and rotatable up and down.

  The middle mounting portion 32 provided on the left front column 1a is configured to mount the lower end portion 16 of the left bellows-like stretchable unit 21 so as to be slidable along the longitudinal direction of the column and rotatable in the vertical direction. The middle mounting portion 32 provided on the left rear column 1b is for mounting the lower end portion 16 of the left bellows-like stretchable portion 21 so as to be slidable along the longitudinal direction of the column and rotatable in the vertical direction. The middle mounting portion 32 provided on the right front column 1c is for mounting the lower end portion 16 of the right bellows-like stretchable portion 22 so as to be slidable along the longitudinal direction of the column and rotatable in the vertical direction. The middle mounting portion 32 provided on the right rear column 1d is for mounting the lower end portion 16 of the right bellows-like stretchable portion 22 so as to be slidable along the longitudinal direction of the column and rotatable in the vertical direction.

  The lower mounting portion 33 provided on the left front column 1a is configured to mount the lower end portion 16 of the front bellows-like stretchable unit 23 so as to be slidable along the longitudinal direction of the column and rotatable in the vertical direction. The lower mounting portion 33 provided on the left rear column 1b is for mounting the lower end portion 16 of the rear bellows-like stretchable portion 24 so as to be slidable along the longitudinal direction of the column and rotatable in the vertical direction. The lower mounting portion 33 provided on the right front column 1c is for mounting the lower end portion 16 of the front bellows-like stretchable portion 23 so as to be slidable along the longitudinal direction of the column and rotatable in the vertical direction. The lower mounting portion 33 provided on the right rear column 1d is configured to mount the lower end portion 16 of the rear bellows-like stretchable portion 24 so as to be slidable along the longitudinal direction of the column and rotatable in the vertical direction.

  These mounting portions 31, 32, and 33 are provided in a member such as a block separate from the support column by vertically penetrating a hole through which the support column is slidable, and the upper or lower end 15 , 16 is provided with a shaft portion that rotatably supports the shaft 16 and can be manufactured as a common part. Then, the upper mounting portion 31 is fixed to the support by fixing means such as screws or welding, and the middle mounting portion 32 and the lower mounting portion 33 are slidable with respect to the support. The bellows-like stretchable portion is temporarily fixed at the position of the middle attachment portion 32 and the lower attachment portion 33 in a state where the bellows-like stretchable portion is extended to an appropriate length. As a temporary fixing method, for example, a positioning hole (not shown) for allowing the pin to pass from the mounting portion to the support may be provided, or a pin may be fixed with a rotatable screw, which may be changed as appropriate. . Of course, these attachment portions 31, 32, and 33 are not necessarily required to be common parts, and in particular, the upper attachment portion 31 may be implemented by providing a bearing for rotation on the support by direct welding or the like. .

  At the time of assembly, as shown in FIG. 2, the left bellows-like stretchable part 21 and the right bellows-like stretchable part 22 are first stretched from the folded state in which each of the bellows-like stretchable parts is contracted. Specifically, the left rear column 1b and the right rear column 1d are pulled rearward to move away from the left front column 1a and the right front column 1c. Thereby, while the left bellows-like expansion-contraction part 21 and the right bellows-like expansion-contraction part 22 extend, the middle attaching part 32 of each support | pillar raises. The raised middle mounting portion 32 is fixed by an appropriate fixing means to maintain the stretched state of the bellows-like stretchable portion. As the fixing means, fixing means generally used for tents such as bolts, nuts, pivots and pins can be appropriately selected and used. In this example, the pin p is used, and as shown in FIG. 4, it is fixed by passing the pin p through a positioning hole provided in the support column. In this positioning hole, an upper positioning hole p1 and a lower positioning hole p2 are provided in each support column, and the middle mounting portion 32 is fixed to p1 through p (FIG. 4B).

  Next, the front bellows-like stretchable part 23 and the rear bellows-like stretchable part 24 are extended. Specifically, the left front column 1a or the right front column 1c is moved in the lateral direction so as to move away from each other, and the left rear column 1b or the right rear column 1d is moved in the horizontal direction so as to move away from each other. As a result, the front bellows-like stretchable part 23 and the rear bellows-like stretchable part 24 extend, and the lower mounting part 33 rises. In this state, p is passed through p2 and fixed (FIG. 4C). . Then, if necessary, if it is a telescopic support, the extension support 10 is extended to complete the frame (FIG. 1).

  Thus, the left bellows-like stretchable part 21 and the right bellows-like stretchable part 22 are attached to the middle attachment part 32, and the front bellows-like stretchable part 23 and the rear bellows-like stretchable part 24 are attached to the lower attachment part 33. Left and right and front and rear can be expanded and contracted separately. Accordingly, even when the tent is stretched by placing an object that hinders the expansion of the frame, the frame can be expanded without moving the bed b diagonally.

Specifically, in order to spread the frame with the medical bed b placed inside in a folded state, the folded frame is placed in the vicinity of the bed b (for example, right front of the bed).
From this state, the left bellows-like stretchable part 21 and the right bellows-like stretchable part 22 are extended. At this time, the left rear strut 1b and the right rear strut 1d move rearward along the right side of the bed b (FIG. 3). (A) arrow a).
Next, the front bellows-like stretchable part 23 and the rear bellows-like stretchable part 24 are extended. At this time, the left front strut 1a and the left rear strut 1b move along the front side and the rear side of the bed b. (Arrow B in FIG. 3A), four struts can be arranged in the square of the bed b without moving the struts on a substantially diagonal line of the bed b.

  On the other hand, the reverse procedure makes it easy to fold only the frame while the interfering object such as the bed is installed.

  The tent is completed by expanding it as described above and supporting the seat on the frame. A sheet | seat can be suitably changed according to a use. If it is a tent for festivals, it can also be implemented only with the top sheet s1. Moreover, if it is for awning, you may use a highly breathable mesh. On the contrary, when used as a clean room for medical purposes, food factories, precision work, etc., it is desirable that the lower end of the side sheet s2 is grounded so as not to create a gap with the ground. However, it is desirable to have a highly airtight structure, and it is also desirable to design the material and connection method of the sheet in consideration of gas barrier properties. The seat support method may be installed so as to cover the frame, or may be suspended in the frame.

  As for the columns, it is essential to provide one for each of the four corners of the quadrangle, but an intermediate column can also be provided between these four columns. Moreover, you may make it reinforce a top part by passing an auxiliary pipe between bellows-like expansion-contraction parts.

It is a perspective view of the tent which concerns on embodiment of this application. (A) is a plan view and a side view of the tent frame in a folded state, and (B) is a plan view and a side view of a process of extending the left bellows-like stretchable part and the right bellows-like stretchable part from the folded state of the tent frame.
