Description

Field of the Invention The present invention relates to a cane-mounted seat plate that can be attached to a cane without modifying a cane in use or a newly manufactured cane (hereinafter referred to as a cane) for the purpose of sitting while standing.

Traditionally, canes have been used as walking aids for the elderly, people recovering from injuries or illnesses, climbers, and pedestrians carrying loads. There has been a demand for a seat plate that can be easily attached to and detached from a cane (hereinafter referred to as a seat plate to be attached) so that the user can take a short rest.

In the improvement of a cane as a chair to sit on, a foldable plate-like body that serves as a handle and seat surface is attached to the upper end of the cane, and a foldable chair leg is attached to the inner cylinder of the cane. Although a seat surface with a lowered height has been proposed, it is not intended for sitting while standing or for diversion to other canes, and is different from the present application in purpose and configuration (for example, Patent Document 1).

A cane that serves as a chair for sitting in an upright position has been proposed that has a seat height adjustment means that can be moved up and down along a support plate that is fixed to the cane trunk and fixed to the cane, and that has a buttock support that supports the buttocks. The chair is also unique and integrated with the cane, which is a modification of the cane.
The purpose of this chair is to sit while standing, but it was improved by fixing a support plate to the stem of the cane. They are very different in purpose and configuration (for example, Patent Document 2).

As a means for locking a foothold at an arbitrary position on a pole in a stilt playground equipment, it has been proposed that the foothold cylindrical portion is pressed and clamped into a cylindrical member with a slit fitted to the pole. It is assumed that it is difficult to secure a foothold to the outer diameter rod, and even if there is some similarity in form with the attached seat plate of the present application, the play equipment is extremely different from the purpose and configuration of the present application (for example, Patent Document 3).

In the first place, the cane is intended to reduce the burden on the legs and lower back and aid in walking, but there are many cases in which a short break is desired even while using the cane. Especially in the case of the elderly, it is common to see people who have pain in their legs and lower back, sit down on a seat made of stone steps or wooden stumps, and after a while stand up and walk painfully. Unable to find a place to sit, we see people standing and resting while holding on to canes with both hands, and hikers with loads on their backs who use their canes to support only the load on their backs.

Here, the object of the present invention is to solve the requirement of sitting while standing and resting the body (especially the lower body) while using a cane, without improving the cane in use as it is. To provide a mounting seat plate for a walking stick, which is lightweight and can be easily and surely mounted.

The configuration of claim 1 of the invention for achieving such an object is a cane mounting seat plate comprising a mounting frame and a seat plate, wherein the mounting frame has an inner space larger than the outer diameter of the cane shaft. It consists of a substantially C-shaped wall with an opening on the side through which a cane can be put in and out. Tightening bolts are attached to the front wall of the wall, and support bolts are attached to the projecting plate provided at the bottom of the rear wall of the wall. is attached, the seat plate has an opening at the tip that is inserted so as to sandwich the wall, the fastening bolt fastens the cane shaft and attaches the mounting frame to the cane, and the support bolt is The gist of this is that the seat plate attached to the mounting frame with its tip end supported by the overhanging portion of the upper portion of the wall is supported from the lower surface side so that the angle in the vertical direction can be adjusted.

The second aspect of the invention is a cane mounting seat plate comprising a mounting frame and a seat plate. Consists of a U-shaped wall, with fastening bolts attached to the door that opens and closes the opening at the front of the wall through which a cane can enter and exit, and support bolts attached to the overhang plate provided at the bottom of the rear wall of the wall. The seat plate has an opening at the tip for insertion so as to sandwich the wall, the fastening bolt fastens the cane shaft to attach the mounting frame to the cane, and the support bolt is the wall The gist of the invention is that the seat plate, which is attached to the attachment frame with its leading end supported by the projecting portion of the upper part of the seat plate, is supported from the lower surface side so that the angle in the vertical direction can be adjusted.

In addition, the mounting frame may be provided with a substantially V-shaped clamping body for clamping the cane shaft inside the rear wall of the wall body and at the tip of the fastening bolt, and the rear wall of the wall body may be attached downward. and the seat plate may be foldable.

Here, the maximum outer diameter of the generally used cane shaft is about 23 mm, and if the opening and inner space of the mounting frame are about 25 mm, it can be attached to most canes. Of course, in the case of a cane with a larger outer diameter than this, the mounting body and seat plate corresponding to it should be used.
The seat plate to be attached to the mounting frame has a substantially rectangular shape and a substantially U-shaped opening at the center of the tip. Matching the shape of the rear wall of the body, this opening is configured to be inserted forward from the rear of the mounting frame.
In addition, if the seat plate is foldable, it will be easier to handle, and at this time, the rear plate will be made to rise upwards to create a sense of stability when sitting. The seat plate is not limited to a substantially rectangular shape, and various forms of materials and plate-top pastes that do not impair the function and design can be selected.

According to this configuration of the invention, when the planar shape of the wall of the mounting frame is approximately C-shaped, it becomes easy to insert and exit the cane through the opening on the side, and when the planar shape is approximately U-shaped, the door can be opened. The cane can be easily put in and taken out from the opening in front of the open. However, in the absence of these openings, a commonly used cane has a grip on the upper end (see FIGS. 4 and 13) and a rubber pad on the lower end (see FIGS. 4 and 12). Therefore, it is extremely inconvenient to remove the accessory one by one and insert it into the mounting frame from the upper end or the lower end of the cane (in the case of a cane with a separate joint, the joint portion).

If the cane shaft to which the mounting frame is attached already has multiple stages of receiving holes, the front wall of the mounting frame and the tip of the fastening bolt attached to the door are convexed and equipped with a receiving plate. If the convex part is aligned with the receiving hole of the cane shaft at a convenient height and the bolt is tightened, the mounting frame is firmly attached to the cane shaft and downwards, together with the pressure on the inside of the rear wall of the wall. There is no deviation. A receiving plate for receiving the cane shaft provided on the projection at the tip of the fastening bolt is curved or substantially V-shaped and rotatably attached to the base of the projection.

In addition, when a substantially V-shaped clamping body is provided on the inside of the rear wall of the wall of the mounting frame and on the tip of the fastening bolt, vertical contact lines on the left and right of the rear clamping body, The contact lines on the cane shaft in four places, including the two vertical contact lines on the left and right of the clamping body in front, create a strong clamping force, and regardless of the presence or absence of a receiving hole in the cane shaft, the mounting frame can be secured. It can be securely attached to the cane shaft body.

The seat plate, which has a substantially U-shaped opening at the tip thereof, is attached to the attachment frame by being pushed so as to sandwich the wall of the attachment frame. In addition, when sitting on the attached seat plate, the seat plate, which has a predetermined thickness (approximately 10 to 20 mm), does not tilt to the left or right, and the two points on the left and right of the tip part overhang the upper end of the wall. In addition to being supported by the support bolts attached to the rear overhang plate, the mounting frame securely supports the seat plate by a total of three parts. In addition, the support bolt has a function of adjusting the angle of the seat plate in the vertical direction and supporting and fixing the seat plate. The distance between the overhanging portion at the upper end of the wall of the mounting frame and the rear overhanging plate should be larger than the sum of the thickness of the tip portion of the seat plate and the angle adjustment margin.

When the rear wall of the wall of the mounting frame is extended downward to create a tailcoat style, when the cane is tilted forward when sitting, the stress applied to the cane due to the body weight is The bolt is mainly received at a portion where the bolt receiving plate or the upper end of the substantially V-shaped clamping body abuts the stick, and a portion where the rear wall of the wall or the substantially V-shaped clamping body lower end abuts against the stick. Therefore, by lengthening the intervals between these parts, the stress applied to the cane shaft is reduced to protect the cane, and the mounting frame is also good in terms of design.

When the seat plate is foldable, it is not conspicuous and not bulky when carried by removing it from the cane or when walking with it attached to the cane. It sometimes has the function of promoting a sense of stability.

The use outline of the present invention with the above configuration is as follows. The seat plate can be attached to the cane by inserting the seat plate into the fastened mounting frame to the full extent of the U-shaped opening, and adjusting the seat plate to the desired angle with the support bolt attached to the rear overhang plate. It is completed (FIG. 4(b)).

When standing and sitting on the seat plate with the cane firmly attached to the cane, the seat plate is facing backward and the cane is facing forward θ° (about 10 to 20°) as shown in the image of standing and sitting in Fig. 4 (c). Sit upright with both legs slightly forward and backward (about 20 cm) and spread to about shoulder width. At this time, the left, right, front, and rear inclinations are balanced by the pressing force of both feet and a cane, but it is possible to sit safely and stably with a few trials. In addition, it is also possible to stand and sit while holding on to a signpost, fence, etc.

In addition, the strength of existing canes varies, and it is possible to adjust the weight on both feet while checking the bending state of the cane when sitting. The burden on the legs and lower back can be reduced by receiving the degree (approximately the weight of the upper body) on the seat board. If a cane with sufficient strength is procured, it is not necessary to check the degree of deflection of the cane.

A mounting seat plate for a cane according to an embodiment of the present invention will be described with reference to the drawings.
