Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a stretcher with a mat, which is hung with a mat placed on a stretcher for transporting a patient.

Prior Art As a prior art, there is Utility Model Application No. 63-77038. In the technique disclosed in this publication, in order to fix the mat on the stretcher, one fitting protrusion is attached to each of the four corners of the mat, and the stretcher is provided with a female snap that receives the fitting protrusion. The fitting protrusion was fitted, and the hooking part of the female snap was hooked to the hooking groove of the fitting protrusion, and the mat was hung on the stretcher.

Problems to be solved by the invention In the hanging tool described in Utility Model Application Publication No. 63-77038, which is shown as a conventional technique, when removing the mat from the stretcher, the mat is grasped and pulled, and the convex tool is fitted into the mat. He was pulling it out of the female snap. When the mat is attached to and detached from the stretcher in this way, the engagement of the claw-shaped latching part with the latching groove is delicate, and the claw-shaped latching part is in an abnormal state and may not fit into the latching groove. If they engage, the fitting protrusion becomes difficult to remove and it becomes difficult to remove the fitting protrusion from the female snap, and when the mat is pulled to remove the fitting protrusion from the female snap, the female snap Otherwise, the fitting protrusion could not be removed from the mat, causing damage to the mat and making attachment and removal operations difficult.

Means for Solving the Problems The present invention provides a stretcher with a mat that allows the mat to be easily attached to and removed from the stretcher, and which uses a stretcher mat hooking member that prevents the mat from coming off the stretcher when used for bathing. The purpose is to

That is, in the present invention, a cylinder 8 whose upper end is closed is screwed onto the back surface of a mat 7 with a bolt 10 and a nut 11 to constitute a stop 9, and a through hole 6 is bored into which the stop 9 is press-fitted into the stretcher 1. This is a stretcher with a mat, in which a stopper 9 is inserted into a through hole 6 and a mat 7 is removably attached to the stretcher 1.

Embodiments Examples of the present invention will be described in detail with reference to the accompanying drawings.

The flat upper surface of the stretcher 1, which is a component of the bathing device, is divided into three parts: an upper body resting part 2, a waist resting part 3, and a leg resting part 4, and a pillow part 5 is provided protruding from one end.

Through holes 6a, 6b,
6c and 6d are opened, through holes 6 are also opened on both sides of the plane of the waist resting part 3, and through holes 6 are opened on both sides of the lower part of the plane of the leg resting part 4.

The mat 7 consists of two pieces, an upper mat 7a and a lower mat 7b.
is latched, and the lower mat 7b is latched from the waist resting part 3 to the leg resting part 4.

Fasteners 9 are fixed to the four corners of the upper mat 7a and the lower mat 7b, respectively, for hanging these upper and lower mats 7a, 7b to the upper body, waist, and leg resting parts 2, 3, and 4 of the stretcher 1. be done.

The stopper 9 is a member for hooking the upper mat 7a to the upper body rest part 2 of the stretcher 1, and similarly extends the lower mat 7b from the waist rest part 3 to both rest parts of the leg rest part 4. It is a member that is hung by hanging.

FIG. 1 is a sectional view taken along the line A-A in FIG. 3, and the stopper 9 shown in FIG. It is screwed using a bolt 10 and a nut 11 which abut against the lower surface of 7a and have a thin disk-shaped head. The other end of the cylinder 8 is open, and a bulge 12 that bulges outward is formed at approximately the center of the length of the cylinder 8 on the outer periphery, and from the bulge 12 to the open end of the cylinder 8. The wall thickness of the cylinder 8 is reduced so that it becomes tapered towards the end.

A through hole 6 into which a stopper 9 is inserted is formed in each placement portion of the stretcher 1. The through holes 6 are formed at the four corners of the upper body rest 2 in alignment with the positions of the stops 9 of the upper mat 7a.

The structure of the stopper 9 and the through hole 6 for fixing the upper mat 7a to the upper body resting part 2 is the same as the structure for fixing the lower mat 7b in the waist resting part 3 and the leg resting part 4, and will not be explained. omitted.

Function The function of the stopper 9 fixed to the mat 7 which is hung on the flat upper part of the stretcher 1 constituting the bathing apparatus will be explained.

Fasteners 9 made by fixing cylinders 8 to the four corners of the upper mat 7a are press-fitted into the through holes 6 made at the four corners of the upper body resting part 2 of the stretcher 1 to fix the upper mat 7a to the upper body resting part 2. do. During this fastening, the bulging part 12 of the stopper 9 presses against the inner wall of the through hole 6, creating a frictional force between the stopper 9 and the through hole 6, or the bulging part 12 presses against the inner wall of the through hole 6, or the bulging part 12 presses against the inner wall of the through hole 6, or the bulge part 12 The stopper 9 is prevented from slipping out from the through hole 6 by the swollen portion 12 being caught on the rear surface of the stretcher.

When inserting the fasteners 9 into the through-holes 6 of each placement part of the stretcher 1, the upper mat 7a near where the fasteners 9 are fixed is grasped and the fasteners 9 are successively inserted into the through-holes 6.

Once the stopper 9 is inserted into the through hole 6, as described above, the swollen portion 12 catches on the back surface of the upper body resting portion 2 or presses against the inner wall of the through hole 6, causing an appropriate frictional resistance. Therefore, the stopper 9 cannot be easily removed from the through hole 6 during normal use of the stretcher 1.

When removing the stopper 9 from the through-hole 6, the stopper 9 is pulled out from the through-hole 6 by pulling upward on a suitable part of the upper mat 7a near the stopper 9, contrary to the insertion method.

The manner in which the lower mat 7b is engaged with and detached from the waist resting part 3 and the leg resting part 4 is the same as the manner in which the upper mat 7a is engaged and detached from the upper body resting part 2. Description is omitted.

Effects of the invention The present invention involves inserting the fasteners fixed to the upper and lower mats into the through holes drilled in the upper plane of each placement part of the stretcher, and attaching the bulges formed on the fasteners to the back surface of the stretcher. The mat is hooked onto the stretcher by hooking or pressing against the inner wall of the through hole to create frictional resistance. According to this configuration, the mat can be easily latched together with the fasteners to each placement portion of the stretcher by simply inserting the fasteners into the through holes.

In addition, by pulling the end of the pine near where the stopper is fastened upward with a force greater than the above-mentioned catching resistance force or a force greater than the frictional resistance force, the stopper can be easily removed from the through hole. It can be pulled out and the mat can be easily removed from the stretcher.

As mentioned above, the present invention allows the fasteners and the mat to be easily attached to and removed from the stretcher, and is very advantageous in terms of handling since the fasteners do not tear off from the stretcher when the mat is removed from the stretcher. It was.

Conventional latching members are constructed by engaging the claw-shaped latching portion provided on the female snap side with the latching groove of the fitting protrusion, so the degree of latching of the claw-shaped latching portion to the latching groove is This greatly affects the removal force of the fitting protrusion. Therefore, if an abnormality occurs in the claw-shaped latching portion, the fitting protrusion becomes difficult to remove, or on the contrary, it becomes impossible to be latched. Since it does not have a shape retaining part, this drawback is solved.

In addition, with conventional latching members, when the tip of the fitting protrusion is removed from the claw-shaped latching part, there is almost no frictional resistance between the fitting protrusion and the female snap, so the fitting protrusion is used as a stretcher. I will leave from.

However, in the present invention, the bulge also has frictional resistance against the inner wall of the through hole, so even if the bulge does not penetrate the through hole, the stopper can come off during normal use. This was not the case, and the structure made it even more difficult for the mat to come off the stretcher during normal use, making it very convenient to use.

In addition, the hanging member of the present invention, which has the structure of the mat stopper and the through hole of the stretcher, does not require the conventional female snaps that fasten to the stretcher, so the number of parts is reduced.
This made it possible to reduce the number of processing points and reduce manufacturing costs.
